[0001] The present invention refers to a fastening device according to the preamble of independent
claim 1 as well as to the preamble of independent claim 5. Furthermore, the present
invention is directed to a waste container, and to a method of mounting a first component
to a second component by making use of a fastening device according to the invention.
Finally, the present invention is directed to different preferred methods of manufacturing
such fastening devices.
[0002] Fastening devices in different configurations are well known for decades.
DE 1 097 117 A for example describes a fastening device which is configured as a cylindrical expansion
dowel. The dowel, which is made of a plastic material, is slotted over a part of its
length. The rear end of the dowel has an opening for inserting a fastening screw.
The front end of the dowel is provided with sawtooth-shaped incisions on the dowel
circumference.
[0003] EP 2 182 223 A2 describes a nail dowel comprising an expansion sleeve and an expansion pin being
a nail, a screw nail, a screw or the like. The expansion pin is arranged in a ready-to-use
state as an insert in the expansion sleeve and is encapsulated with the material that
forms the expansion sleeve. However, the expansion pin is not completely, but only
partially encapsulated. The expansion pin can thus be driven into a receiving space
of the expansion sleeve after the nail dowel has been introduced into a borehole.
The expansion sleeve expands outwardly and the nail dowel can get fastened in the
ground. In order to get this nail dowel manufactured, the expansion pin made of steel
is inserted as an insert into an injection moulding tool. Next, the expansion sleeve,
which is made of plastic, partially encapsulates the expansion pin during an injection
moulding step. However, this method is complex and it needs several manufacturing
steps.
[0004] Fastening devices which are configured as so-called hinge pins and which form part
of a hinge device, are widely used to pivotably secure a first component, a lid device
for example, to a second component, a container body of a container for example. Such
a container can be provided as a waste container for example. In the latter case,
such hinge pins are generally used to pivotably link a lid device to a waste container
body.
[0005] Known hinge pins of that kind, which are generally provided as solid body components,
are made of an elastomeric material. Their diameter is slightly larger than the diameter
of a receiving sleeve of the hinge device. The hinge pins are hammered into the receiving
sleeve under the exertion of an impact force. As a result, the hinge pins are squeezed
together and thus generate a form-fitting connection.
[0006] In recent years it has become more and more known to provide such waste containers
with a modular configuration. That means that the different components, such as the
lid device, the container body and the like are manufactured as individual components
which can get freely combined and which can get individually exchanged, if necessary.
This usually happens on-site. However, in order to remove a hinge pin as described
before it is at least necessary to use a special tool. This is time-consuming and
carries the risk of injuries. Other hinge pins cannot get removed anymore or they
are destroyed during the removal procedure.
[0007] A different problem with such hinge pins is that the hinge pin diameter must be synchronized
to the inner diameter of the receiving sleeve of the hinge device. If the hinge pin
diameter is too large, it is not possible to push the hinge pin into the receiving
sleeve of the hinge device. On the other hand, if the hinge pin diameter is too small,
no adequate connection can get realized. In situations, where an exchange of a hinge
pin due to the exchange of a respective component of the waste container takes place
on-site, it is therefore necessary to have different sized hinge pins at hand. This
leads to an increased effort. This effect is increased by a number of elements added
in the modular system in time or with modifications of existing elements. With each
new element or change, the tolerance field increases. In time hinge pins therefore
need to adapt to growing tolerances.
[0008] The general principles as described in
EP 2 218 223 A2 are therefore not suitable to get transferred to such hinge pins as described above,
since they are not universally useable with hinge devices, in particular receiving
sleeves of hinge devices, of different sizes.
[0009] In the field of manufacturing, handling and maintaining of waste containers, manufacturing
costs and time are significant factors. Furthermore, in view of a circular economy,
it is more and more important to provide components that can get re-used.
[0010] Therefore, it is the object of the present invention to provide a fastening device,
in particular a hinge pin, said fastening device consisting of an expansion sleeve
and an expansion pin being provided as a drive-in pin, wherein the fastening device
is universally useable for different sized applications, in particular receiving sleeves,
wherein the fastening device can get re-used, and wherein, at the same time, the fastening
device can get manufactured easily and cost-effectively.
[0011] In accordance with the present invention, this object is solved according to a first
aspect of the invention by the fastening device with the features according to independent
claim 1, according to a second aspect of the present invention by the fastening device
with the features according to independent claim 5, according to a third aspect of
the present invention by the waste container with the features according to independent
claim 12, according to a fourth aspect of the present invention by the method of mounting
a first component to a second component by means of such a fastening device according
to the present invention according to independent claim 14, and according to a fifth
aspect of the present invention by the method of manufacturing such a fastening device
according to the present invention according to independent claim 15.
[0012] Additional features and details of the present invention become apparent from the
dependent claims, from the description and from the drawings. Therein, features and
details which are described in connection with one of the aspects according to the
invention apply with respect to their disclosure in their entirety also to the other
aspects according to the invention, so that statements made with respect to one aspect
of the invention also apply to their full extent to the other aspects of the invention,
and vice versa.
[0013] According to the first aspect, which comprises the features of independent claim
1 the elongated expansion pin is configured in a special way. According to the second
aspect, which comprises the features of independent claim 5, the fastening device
consisting of the expansion sleeve and the expansion pin is configured in a special
way. However, both aspects underlie the same common basic idea, that a fastening device
is provided that can get easily and cost-efficiently manufactured, whereby the fastening
device is universally useable on site in connection with different sized applications,
and wherein the fastening device can get re-used. Preferred embodiments for both aspects
are described in more detail further below. The fastening device according to the
first aspect of the invention as well as the fastening device according to the second
aspect of the invention have the following features in common.
[0014] According to both aspects, a fastening device is provided. In particular, a fastening
device is used to securely connect two different components with one another, whereby
a first component is fastened to a second component, or vice versa. According to a
preferred embodiment, the fastening device is provided for pivotably connecting the
two components with one another. In such a case the fastening device is preferably
provided as a hinge pin, said hinge pin being part of a hinge device. Some preferred
embodiments of applications using such a fastening device are described in more detail
further below.
[0015] As a first component, the fastening device comprises an expansion sleeve, said expansion
sleeve having an elongated hollow sleeve body. In particular, the sleeve body is an
elongated body that is hollow on the inside and open on both end faces, and that has
a length which is greater than its maximum internal diameter.
[0016] The present invention is not limited to specific cross-sections for the hollow sleeve
body. For example, the hollow sleeve body can have a rectangular or square or triangular
cross-section. According to a preferred embodiment the hollow sleeve body has a circular
cross-section. In this case, the hollow sleeve body has a circular inner diameter,
and the hollow sleeve body is provided as a cylindrical sleeve body.
[0017] The sleeve body, in particular the wall or walling of the sleeve body, comprises
one or more, preferably four, longitudinal slots, which are provided spatially spaced
from one another in the sleeve body, in particular in the wall or walling of the sleeve
body. That means that the slots run in a lengthwise dimension or direction. If the
hollow sleeve body is provided as a cylindrical sleeve body, it is preferably provided
that the slots are evenly distributed over the perimeter of the sleeve body. In particular,
the slots extend over a part of the lengths of the sleeve body. In particular, the
material areas between two adjacent slots are configured as tongues or straps. Due
to a force that is exerted from the inside of the sleeve body against the material
areas between two adjacent slots, these material areas can get pushed outwards. Due
to said force the material areas between two adjacent slots get expanded in an expansion
direction, which is preferably perpendicular or almost perpendicular to the moving
direction of an expansion pin, which will be explained in more detail further below.
The slot or slots provide the flexibility for an easy assembly of the fastening device,
as will be explained in more detail further below.
[0018] The present invention is not limited to a specific number of slots. At minimum it
is necessary that the hollow sleeve body comprises one such slot. However, it is preferred
that the hollow sleeve body comprises two or more such slots, three or four slots
for example. According to a preferred embodiment, the hollow sleeve body comprises
four slots. Four slots give the hollow sleeve body sufficient flexibility to get it
easily assembled in a receiving sleeve. This will be described in more detail further
below. Furthermore, the hollow sleeve body gets evenly in contact with the receiving
sleeve, when the fastening device is activated.
[0019] As a second component, the fastening device comprises an elongated expansion pin
being provided as a drive-in pin. In particular, a drive-in pin is a pin that gets
pushed into the hollow sleeve body, when an impact force is exerted onto the pin.
The expansion pin comprises a first end portion and a second end portion being opposite
to the first end. The first end portion ends up in a first end, and the second end
portion ends up in a second end. The first end portion comprises a head element which
is provided for receiving the impact force, which can get exerted by means of a hammer
or another suitable tool for example. The second end portion, in particular the second
end, may comprise a chamfer for better guiding and positioning
[0020] The hollow sleeve body comprises a receiving space, whereby the wall or walling of
the hollow sleeve body borders the receiving space. The receiving space is provided
for receiving and particularly guiding the expansion pin being inserted into and pushed
through the sleeve body, by means of an impact force being exerted on the expansion
pin, in particular on the head element thereof. The sleeve body comprises a first
end portion providing an insertion opening for the expansion pin and a second end
portion opposite to the first end. The first end portion ends up in a first end, and
the second end portion ends-up in a second end. The first and/or second end portion,
in particular the first and/or second end, may comprise a chamfer for better guiding
and positioning.
[0021] When the expansion pin is pushed through the receiving space of the hollow sleeve
body, at least parts of the outer surface of the expansion pin get in contact with
the inner surface of the hollow sleeve body, in particular with the wall or walling
thereof. The expansion pin exerts a pressure force on the inner surface of the hollow
sleeve body, in particular on the material areas being provided between adjacent slots
in the sleeve body, such that the material areas between the slots get expanded outwards.
For that reason, the overall expansion of the expansion pin perpendicular to the lengthwise
expansion of the expansion pin is preferably a bit longer than the inner diameter
of the hollow sleeve body. Thus, the moving expansion pin will expand the sleeve body
of the expansion sleeve, in particular the material areas between adjacent slots,
by means of which any tolerance in a receiving sleeve of a component can get bridged,
for which the fastening device is used, and which will be described in more detail
further below.
[0022] According to the first aspect of the invention as claimed in independent claim 1,
the elongated expansion pin is provided in a specific way. According to this first
aspect, the elongated expansion pin comprises a longitudinal profile element, or the
elongated expansion pin is provided as a longitudinal profile element. That means
that the profile element runs in a lengthwise dimension or direction. Furthermore,
it is preferably provided that the profile element has a length which is greater than
its maximum diameter. The profile element can be configured in different ways. Therefore,
the present invention is not limited to any specific configurations. Nevertheless,
a number of advantageous embodiments thereof are described in more detail further
below.
[0023] The elongated expansion pin comprises at least one, in particular longitudinal, rib
element, which protrudes outwardly from an outer surface of the longitudinal profile
element. In particular a rib element is a narrow strip element that is placed or shaped
or provided or formed on the outer surface of the longitudinal profile element.
[0024] According to the invention it is sufficient that the elongated expansion pin comprises
only one such rib element. However, for sufficient stability and a secure connection
it is preferably provided that the elongated expansion pin comprises two or more such
rib elements, which are provided spatially spaced from one another on the outer surface
of the longitudinal profile element. It is preferably provided that the rib elements
are evenly distributed over the perimeter of the elongated expansion pin. If the expansion
pin comprises two or four rib elements, two rib elements are preferably provided at
opposite sides of the expansion pin respectively.
[0025] According to the first aspect of the invention, the or each rib element is provided
for exerting a pressure force on an inner surface of the sleeve body when the expansion
pin gets inserted into the receiving space of the sleeve body and pushed therethrough.
When the expansion pin is pushed through the hollow sleeve body, the at least one
rib element gets in contact with the inner surface of the hollow sleeve body as explained
further above. Thus, a form fit and/or a frictional fit is generated between the outer
surface of the hollow sleeve body and a component surrounding the sleeve body, a receiving
sleeve for the fastening device for example.
[0026] Preferably, the overall diameter of the profile element including the at least one
rib element is slightly greater than the inner diameter of the receiving space pf
the hollow sleeve body.
[0027] According to a preferred embodiment, the at least one rib element has a triangular
shape. In general, a triangle is a polygon with three edges. With one of these edges
the triangular rib element is connected to the longitudinal profile element of the
elongated expansion pin. Opposite to this "connecting edge" the triangular shaped
rib element comprises a triangle-tip, said triangle-tip being provided to get in contact
with the inner surface of the hollow sleeve body. According to a preferred embodiment,
the rib element is configured as an elongated member, an elongated profile element
for example, said member or profile element particularly havening a constant and unchanging
triangular cross-section.
[0028] Therefore, the area of the rib element which comes in contact with the hollow sleeve
element is very small, such that the impact force which is necessary to push the expansion
pin through the hollow sleeve body is not too great. On the other hand, the triangular
configuration of the rib element allows a firm fit of the expansion pin inside the
sleeve body.
[0029] When the expansion pin gets pushed inside the hollow sleeve body and into a "locking
position", the triangular rib elements press the hollow sleeve body, in particular
the material areas between two adjacent slots in the sleeve body, against a component
surrounding the fastening device, a receiving sleeve for example. The impact force
that is exerted on the expansion pin, is transferred to the hollow sleeve body via
the triangular rib elements whereby the tips of the triangular rib elements are in
contact with the inner surface of the hollow sleeve body, whereby the triangular rib
elements press and/or cut and/or shear the hollow sleeve body, in particular the wall
or walling thereof. If the component surrounding the fastening device, the elongated
hollow sleeve body thereof for example, is bigger, than the triangular rib elements
will not cut so deep into the material of the hollow sleeve body, but will result
in a larger expansion of the sleeve body due to the pressure force exerted on the
inner surface of the sleeve body by the rib elements. Therefore, the arrangement and
configuration of the rib elements allow to create more flexibility and/or to cover
deviations.
[0030] According to a preferred embodiment, the length of the at least one rib element is
shorter than the length of the longitudinal profile element. That means that the rib
element extends over a part of the length of the longitudinal profile element. At
least one end of the rib element(s) in particular the end facing the sleeve body,
preferably comprises a chamfer for better guiding and positioning.
[0031] In general, the present invention is not limited to specific geometrical values for
the different components of the fastening device. According to an exemplary embodiment,
the hight of the rib elements may be in a range between 0.3mm and 0.7mm, preferably
0.5mm. The inner diameter of the hollow sleeve body, if the sleeve body has a cylindrical
configuration, may vary between 15mm and 20mm, preferably between 19.2mm and 19.7mm.
The expansion sleeve may have a length between 40mm and 60mm, preferably a length
of 50mm.
[0032] According to the second aspect of the present invention, or alternatively as a preferred
embodiment in accordance with the first aspect of the present invention, the fastening
device comprises the features according to independent claim 5.
[0033] According to the second aspect of the present invention, the elongated expansion
pin and the sleeve body are connected to one another via at least one material bridge.
[0034] In its initial state, and before the expansion pin gets pushed inside the hollow
sleeve body for its operational mode, the fastening device is provided as one single
member, said fastening device comprising the expansion sleeve and the expansion pin
being integral parts thereof. In general, a material bridge is a, in particular integral
or bonded, connection between two components, between the hollow sleeve body and the
expansion pin in the present case. The material bridge has a thickness that is sufficient
to hold the expansion pin and the hollow sleeve body together during transportation
and storage of the fastening device. At the same time, the material bridge must be
as thin as possible such that the expansion pin and the hollow sleeve body can get
separated from each other without any complications, when the impact force is exerted
on the expansion pin. The present invention is not limited to specific thickness values
for the material bridge. According to a preferred embodiment, which however does not
delimit the scope of protection, the material bridge has a thickness of less than
1mm, a thickness between 0.3mm and 0.6mm for example. Using such a material bridge
between the expansion pin and the hollow sleeve body allows to manufacture the entire
fastening device in one piece and in one single manufacturing process. Embodiments
for suitable manufacturing processes are described in more detail further below. According
to a preferred embodiment, the material bridge is provided as a film hinge or a film
gate.
[0035] For the purpose of the present invention, it is generally sufficient to provide only
one such material bridge. However, according to a preferred embodiment, two or more
material bridges are provided for stability reasons and for more robustness of the
fastening device.
[0036] According to a preferred embodiment, the material bridge connects the second end
portion, in particular the second end thereof, of the expansion pin with the first
end portion, in particular the first end thereof, of the hollow sleeve body. Dependent
on the configuration of the fastening device, the material bridge can be realized
at a different location.
[0037] In the following, a number of different embodiments are described for the longitudinal
profile element of the elongated expansion pin. For example, the longitudinal profile
element can be configured as a solid material element or as a hollow profile element,
each preferably having a cross-section or contour which corresponds to the cross-section
or contour of the hollow sleeve body, in particular the receiving space thereof. For
example, if the hollow sleeve body has a cylindrical shape having a receiving space
with a circular cross-section, the longitudinal profile element of the elongated expansion
pin may have a circular cross-section as well. If the receiving space of the hollow
sleeve body comprises a rectangular or square cross-section, the longitudinal profile
element of the elongated expansion pin can be configured accordingly.
[0038] According to a preferred embodiment, the longitudinal profile element of the elongated
expansion pin is provided as a cross-profile element. The cross-profile element comprises
four legs or arms, that intersect vertically and centrally. In particular, all legs
or arms have the same length and/or width. Each leg or arm has a first end that is
directed to respective first ends of the other legs or arms, whereby the four legs
or arms are connected or joined to each other via their first ends respectively. Furthermore,
each leg or arm has a second end opposite to its first end, said second end being
a free end. At least one rib element is provided at a secon end of at least one of
the legs or arms. In general, it is sufficient for the present invention, that only
one rib element is provided at one leg or arm. However, for stability reasons and
for providing a secure connection between the expansion pin and the hollow sleeve
body, two or more, preferably four, rib elements are provided at the legs or arms.
If two rib elements are used, the rib elements are provided at free ends of such legs
or arms, which are opposite to each other. If four rib elements are used, each free
end of each leg or arm is provided with a rib element respectively.
[0039] According to a preferred embodiment, the head element of the expansion pin has a
shape and/or size that corresponds to the shape and/or size of the receiving space
of the sleeve body and/or of the insertion opening of the sleeve body. This allows
a better guiding and positioning of the expansion pin inside the hollow sleeve body.
[0040] The present invention is not limited to specific embodiments for the head element
of the expansion pin. It is onepurpose of this head element to receive an impact force,
by means of which the expansion pin gets pushed and moved through the receiving space
of the hollow sleeve body of the expansion pin. According to a preferred embodiment
the head element has a circular shape. According to a different preferred embodiment,
the head element has the shape of the longitudinal profile element of the expansion
pin. In this case the head element can be provided by an end of the longitudinal profile
element.
[0041] According to yet another preferred embodiment the head element has the shape of a
cross. In such a case the insertion opening of the sleeve body may have a corresponding
cross shape as well. By use of such a head element the expansion pin can get easily
re-used. The cross-shaped head element preferably comprises a base area being square
or almost square in shape. The four legs or arms of the cross are provided in each
corner of the base area, and they protrude from these corners to the outside beyond
the base area.
[0042] In order to increase the static friction, at least one clamping tooth, or at least
one clamping hook, or at least one sawtooth-shaped arrangement consisting of two or
more clamping teeth or hooks is provided which protrudes from an outer surface of
the sleeve body, in particular from a material area between two slots in the sleeve
body.
[0043] Preferably the height of the tooth/teeth or hook/hooks of the sleeve element is selected
or determined in a defined relationship and/or dependent to the height of the rib
element or rib elements of the elongated expansion pin. In particular, the height
of the tooth/teeth or hook/hooks of the sleeve element is selected or determined proportionally
to the height of the rib element or rib elements of the elongated expansion pin. If
the hight of the rib element(s) is reduced, for less friction during the push-in movement
of the expansion pin into the hollow sleeve body for example, this reduction in height
is compensated by enlarging the height of the tooth/teeth or hook/hooks at the outside
of the sleeve body.
[0044] According to a preferred embodiment, the second end portion of the sleeve body, in
particular the second end thereof, provides an exit opening for the expansion pin.
When the fastening device gets activated, the expansion pin is pushed through the
insertion opening into the receiving space of the hollow sleeve body. If the fastening
device gets deactivated, the expansion pin must get pushed out of the hollow sleeve
body again. However, in contrast to the known solutions described further above, it
is no longer necessary to use a special tool. By exerting an impact force on the head
area of the expansion pin again, by means of a simple hammer for example, the expansion
pin gets further pushed through the hollow sleeve body and finally through the exit
opening, whereby the expansion pin can leave the hollow sleeve body via the exit opening.
According to a preferred embodiment, the insertion opening provided by the first end
portion of the sleeve body and the exit opening each have the same diameter and/or
the same cross-section. According to a different embodiment, the insertion opening
provided by the first end portion of the sleeve body and the exit opening each have
a different diameter and/or a different cross-section.
[0045] According to yet another preferred embodiment, the expansion sleeve comprises a sleeve
head which is provided at the first end portion of the sleeve body, in particular
at the first end thereof, said sleeve head having a larger diameter and/or a larger
cross-sectional area than the hollow sleeve body. In such a case the sleeve head surrounds
the insertion opening of the hollow sleeve body as well. In particular, the sleeve
head functions as some kind of a stop element, which prevents the hollow sleeve element
from completely entering and disappearing inside the receiving sleeve, and which prevents
the components being fastened by the fastening device from sliding-off from the fastening
device. According to a preferred embodiment, the expansion sleeve additionally comprises
a fixation ring being provided between the sleeve body and the sleeve head. The fixation
ring, which also has the function of a guiding section, may have a diameter lying
between the diameter of the sleeve head and the sleeve body. Either the sleeve head,
as well as the fixation ring may comprise at least one chamfer for better guiding
and positioning.
[0046] According to a preferred embodiment, the second end portion of the expansion pin
has an inclined, in particular a conically tapered, course, which ends-up in the second
end of the expansion pin. By this, positioning and guiding of the expansion pin is
increased, in particular if the expansion pin is re-used. If a material bridge as
mentioned above is used, the material bridge can be realized, where the inclination
of the second end portion of the expansion pin starts. According to another preferred
embodiment, the material bridge can be realized at the second end of the expansion
pin or somewhere in the inclined course of the second end portion of the expansion
pin.
[0047] According to a preferred embodiment, the expansion sleeve and the expansion pin are
made of a plastic material, preferably of the same plastic material. The present invention
is not limited so specific plastic materials. For example, the expansion pin and the
hollow sleeve body can be made of High-Density-Polyethylene (HDPE), of a plastic material
on a Polyolefins basis, of a recyclate plastic material, of a regrinded plastic material
or the like. In particular, the plastic material used for the fastening device is
an injection mouldable plastic material or a plastic material that can be used in
an additive manufacturing process such as 3D-printing.
[0048] Since it is possible to re-use the fastening device, at least the hollow sleeve body
and/or the expansion pin thereof, the fastening device is a suitable contribution
to the circular economy.
[0049] How the fastening device according to the invention is used to fasten two components
with one another will be explained in more detail with regard to the method according
to the fourth aspect of the invention further below. Therefore, the disclosure of
the fourth aspect of the invention applies with respect to its disclosure in entirety
also to the fastening device according to the invention, so that all of the statements
made with respect to fourth aspect of the invention also apply to their full extent
to the fastening device according to the first and second aspects of the invention,
and vice versa.
[0050] In general, the fastening device according to the present invention is capable of
connecting a first component to a second component. The present invention is thereby
not limited to specific fields of application. According to a preferred embodiment,
the fastening device is provided as a hinge pin. A hinge pin, which is part of a hinge
device, serves to pivotably connect a first component with a second component. Therefore,
the fastening device is capable of pivotably connecting two different components with
each other. According to a preferred embodiment, the hinge device comprises a hinge
pin, which is the fastening device, as well as a receiving sleeve, into which the
hinge pin gets inserted.
[0051] According to a preferred embodiment, the fastening device, in particular the hinge
pin, is used in the field of containers, such containers having a container body and
a lid device. By means of a hinge device, which incorporates the fastening device
in form of a hinge pin, the lid device gets pivotably connected to the container body.
The present invention is not limited to specific types of containers. Such containers
can be realized as any small, medium or large sized containers, which are used for
storing and/or transporting any kind of goods.
[0052] According to a preferred embodiment, which however does not delimit the scope of
protection, the fastening device is used in connection with a waste container for
at least temporarily storing waste and/or any kinds of valuable substances, such as
glass, metal, plastic, organic waste, paper, residual waste and the like.
[0053] Therefore, according to the third aspect of the invention, a waste container is provided,
which comprises the features of independent claim 12.
[0054] This waste container comprises a container body. Furthermore, the waste container
comprises a lid device for covering a receiving opening being provided in the container
body. The lid device is pivotally mounted to the container body. Preferably, the lid
device is pivotally mounted to the container body via a hinge device, said hinge device
comprising a fastening device, in particular a hinge pin, according to the first and
second aspect of the invention. Therefore, the disclosure of the first aspect and
of the second aspect of the invention apply with respect to the disclosure in entirety
also to the waste container according to the third aspect of the invention, so that
all of the statements made with respect to first and second aspect of the invention
and with respect to the general description of the invention also apply to their full
extent to the third aspect of the invention, and vice versa.
[0055] According to a preferred embodiment, the hinge device comprises at least one lid
eyelet being provided at the lid device, as well as a hinge sleeve being provided
at the container body. In this case, the hinge sleeve corresponds to the term "receiving
sleeve" which is often used in connection with the fastening device as described further
above. According to a preferred embodiment, the hinge sleeve is provided by a handle
tube of the container body. According to this embodiment, the fastening device, in
particular the hinge pin, is guided or capable of getting guided through the lid eyelet
of the lid device, and is inserted or is capable of getting inserted into the hinge
sleeve of the container body.
[0056] In the following, preferred embodiments of such a waste container, which is equipped
with a fastening device according to the invention, are described in detail.
[0057] Such a waste container may have a holding capacity between 200 litres and 700 litres.
Nevertheless, the present invention is also applicable in connection with larger waste
containers having a holding capacity of up to 1700 litres. In any case the present
invention is not limited to waste containers having a specific holding capacity.
[0058] In particular the waste container is a movable waste container, which means that
the waste container is equipped with a number of wheels, two, three or four wheels
for example. In particular the wheels are attached to the waste container at its lower
end, in the area of the container bottom for example.
[0059] In its basic configuration the waste container comprises at least a container body.
The container body comprises a side wall which sideways borders a receiving space
inside the container body. The present invention is not limited to specific shapes
and configurations of the side wall and therefore, of the container body. For example,
the side wall can have a round shape, an elliptical shape, an oval shape or the like.
According to a different embodiment, the side wall can have a polygonal shape. According
to a preferred embodiment the side wall comprises a rectangular shape or a shape approaching
at least a rectangle, such that the container body shows a respective shape as well.
[0060] Downwardly closed is the container body by means of a base element, which is the
bottom of the container body and from which the side wall protrudes upwardly. Preferably,
the height of the sidewall is greater than, in particular a multiple of, the width
and/or of the depths of the bottom of the container body. At the upper end of the
side wall, which is, in comparison to the container bottom, the opposite end of the
side wall, and which represents and defines the upper edge of the container body as
well, the container body comprises a receiving opening for the waste and/or for the
valuable substances. According to a preferred embodiment, the receiving opening is
bordered by the sidewall of the container body, such that the receiving opening spans
the entire cross section of the container body at its upper end or edge.
[0061] The sidewall and the bottom element of the container body limit an inner space of
the container body, said inner space defining and being the receiving space for storing
the waste and/or the valuable substances.
[0062] For the purpose of storing different fractions of waste and/or of valuable substances
at the same time, it is preferably provided that the inner space of the container
body is divided into a number of different compartments, for example by use of one
or more separation plates, by use of additional insertion containers or by uses of
a combination thereof.
[0063] For covering the receiving opening, the waste container is provided with a lid device,
said lid device being mounted to the waste container, to the container body for example.
The lid device comprises a lid body and at least one handle device being provided
at the lid body. By means of the handle device, the user can open and close the lid
device. It is sufficient that the lid body comprises only one handle device. Nevertheless,
according to a preferred embodiment, the lid device comprises two such handle devices
which are arranged on the lid body.
[0064] According to a preferred embodiment the lid device is pivotally mounted to the container
body at the upper edge of the container body. This can be achieved by means of at
least one hinge device. According to a preferred embodiment, the lid device is configured
as a hinged lid device. The hinge device comprises at least one hinge sleeve, which
acts as a receiving sleeve for the fastening device, a hinge pin in this case. The
hinge device can be provided by a handle tube of the waste container, which is associated
to the waste container body.
[0065] Next, and according to the fourth aspect of the invention, a method is provided,
how a first component, in particular a lid device, can get mounted to a second component,
in particular a container body, by means of a fastening device according the first
and second aspects of the invention, whereby the method comprises the steps of independent
claim 14. In this respect, the disclosure of the first, second and third aspect of
the invention apply with respect to the disclosure in entirety also to the method
according to the fourth aspect according to the invention, so that all of the statements
made with respect to first, second and third aspect of the invention and with respect
to the general description of the invention also apply to their full extent to the
fourth aspect of the invention, and vice versa.
[0066] In a first step, the elongated hollow sleeve body of the expansion sleeve is inserted
into at least one receiving sleeve of a second component. In case of a waste container,
this second component is a waste container body. In this context, the receiving sleeve
preferably is a handle tube, the waste container body being equipped with. In such
a case the fastening device and the receiving sleeve preferably are part of a hinge
device. This hinge device preferably comprises at least one lid eyelet being provided
at the lid device, as well as a hinge sleeve being provided at the container body,
said hinge sleeve being provided by the handle tube for example. Once the lid device
has been placed on the container body, the elongated hollow sleeve body of the expansion
sleeve is guided through the lid eyelet of the lid device, and is inserted and pushed
into the hinge sleeve of the container body, into the handle tube for example. The
sleeve head of the expansion sleeve prevents the sleeve body from entirely sliding
into the hinge sleeve.
[0067] In a next step, by exerting an impact force onto the head element of the expansion
pin being defined by the first end portion, in particular by the first end, of the
expansion pin, by means of a hammer for example, the elongated expansion pin is pushed
into the receiving space of the hollow sleeve body via the insertion opening that
is provided by the first end portion, in particular at the first end, of the sleeve
body. If the elongated expansion pin and the hollow sleeve body are connected to one
another via at least one material bridge, as described in accordance with the second
aspect of the invention, the material bridge gets destroyed due to the impact force
and both components get separated from each other such that the expansion pin can
now freely move through the hollow sleeve body.
[0068] When the expansion pin is pushed through the receiving space of the sleeve body into
its "locking position", by means of a push with a hammer or the like for example,
the expansion pin expands the expansion sleeve, in particular the sleeve body, outwards,
under aid of the one or more, preferably four, longitudinal slots, which are provided
spatially spaced from one another in the sleeve body. In particular, the material
areas between two adjacent slots get pushed outwards and therefore, get outwardly
expanded, due to the rib elements for example, which protrude outwardly from the outer
surface of the longitudinal profile element of the expansion pin. In particular, the
rib elements, which can have a triangular shape, press the hollow sleeve body, in
particular the material areas between two adjacent slots in the sleeve body, against
the inner wall of the receiving sleeve, the handle tube for example. The impact force
that is exerted on the expansion pin, is transferred to the hollow sleeve body via
the rib elements whereby the tips of the rib elements get in contact with the inner
surface of the hollow sleeve body, whereby the triangular rib elements press and/or
cut and/or shear the hollow sleeve body, in particular the wall or walling thereof.
Preferably, the sleeve body, in particular the material areas between adjacent slots
get expanded in an expansion direction, which is perpendicular or almost perpendicular
to the direction of the movement of the expansion pin through the hollow sleeve body.
By means of this, any tolerances in the receiving sleeve, the container handle for
example, can get bridged.
[0069] Finally, upon the expansion of the expansion sleeve, in particular the sleeve body,
the expansion sleeve gets pressed against an inner wall of the receiving sleeve, thus
generating a form fit and/or a force fit connection.
[0070] Disassembly works in a similar way. Then, the expansion pin must get pushed out of
the hollow sleeve body again. By exerting an impact force on the head area of the
expansion pin again, by means of a simple hammer for example, the expansion pin gets
further pushed through the hollow sleeve body and finally through the exit opening
of the hollow sleeve body, whereby the expansion pin can leave the hollow sleeve body
via the exit opening. The expansion pin can be received by and inside the handle tube.
[0071] In the following, different methods are explained, how the fastening device according
to the present invention can get manufactured. It is assumed that the fastening device
is made of a plastic material, and that the fastening device can get manufactured
in one single manufacturing step.
[0072] According to the methods according to the fifth aspect of the present invention according
to independent claim 15, the fastening device is manufactured by means of an injection
moulding process, in particular by means of a One-Component (1K)-Injection-Moulding-Process.
Therefore, it is preferably provided that the fastening device according to the first
and second aspect of the invention is made by an injection moulding process. Injection
moulding per se is well known in the art. In general, it is a manufacturing process
for manufacturing parts by injecting molten material into a mould. In a first step,
the material to be used, plastic material in the present case, is melted. Then the
molten material is injected into the mould cavity, where it cools down and hardens
to the configuration defined by the mould cavity. In case that the expansion pin and
the hollow sleeve body of the fastening device are connected to one another via a
material bridge, an injection moulding process is very suitable to manufacture the
fastening device as one single part in one single manufacturing processing step. For
manufacturing the fastening device, a conventional injection moulding process can
be used, full-automatic with an injection moulding tool with jaw design and a slide
tool, as well as with a hotrunner.
[0073] According to a different method according to independent claim 15, the fastening
device is manufactured by means of an additive manufacturing process, in particular
by means of a 3D-printing process. Therefore, it is preferably provided that the fastening
device according to the first and second aspect of the invention is made by an additive
manufacturing process. Additive manufacturing is a computer-controlled process that
creates three dimensional objects by depositing materials, usually in layers. The
objects to be manufactured are built layer by layer, which is in contrast to traditional
manufacturing processes, which often require machining or other techniques to remove
surplus materials. In case that the expansion pin and the hollow sleeve body of the
fastening device are connected to one another via a material bridge, an additive manufacturing
process is very suitable to manufacture the fastening device as one single part in
one single manufacturing processing step
[0074] However, the present invention is not limited to the aforementioned manufacturing
processes.
[0075] As a basic member, that have all different aspects of the invention in common, the
present invention relates to a fastening device, said fastening device comprising
an expansion sleeve having an, in particular cylindrical, elongated hollow sleeve
body, wherein the sleeve body comprises one or more, preferably four, longitudinal
slots, which are provided spatially spaced from one another in the sleeve body, an
elongated expansion pin being provided as a drive-in pin, wherein the sleeve body
defines a receiving space, which is provided for receiving and guiding the expansion
pin being inserted into the sleeve body. In order to provide a the fastening device
that is universally useable for different sized applications, and wherein, at the
same time the fastening device can get manufactured easily and cost-effectively, it
is provided according to the present invention, that the elongated expansion pin comprises
a longitudinal profile element, that the elongated expansion pin comprises at least
one, in particular longitudinal, rib element protruding outwardly from an outer surface
of the longitudinal profile element, and that the rib element is provided for exerting
a pressure force on an inner surface of the sleeve body, when the expansion pin gets
inserted into the receiving space of the sleeve body. Alternatively, or in combination,
the elongated expansion pin and the sleeve body are connected to one another via a
material bridge, said material bridge connecting the expansion pin with the sleeve
body.
[0076] For a better understanding of the present invention, a preferred embodiment of the
present invention will now be described by way of an example with reference to the
accompanying drawings, in which
- Figures 1 to 4
- depict several views of a first embodiment of a fastening device according to the
present invention;
- Figure 5
- depicts a situation, where the different components of the fastening device according
to the first embodiment are connected to each other by way of a material bridge;
- Figure 6
- schematically depicts the basic functionality of the fastening device according to
the present invention;
- Figures 7 to 10
- depict several views of a second embodiment of a fastening device according to the
present invention; and
- Figures 11 to 15
- depict several views, how the fastening device according to the invention is used
with a waste container.
[0077] All of the Figures show a fastening device 10, which is used in connection with a
waste container 50.
[0078] Figures 1 to 4 show the general construction of the fastening device 10 according
to a first embodiment, which is used as a hinge pin. The fastening device 10 comprises
two major components, an elongated expansion sleeve 11 and an elongated expansion
pin 12. The expansion sleeve 11 comprise an elongated hollow sleeve body 13. The sleeve
body 13 is an elongated body that is hollow on the inside and open on both end faces.
The hollow sleeve body 13 has a circular inner diameter, and thus, the hollow sleeve
body 13 is provided as a cylindrical sleeve body 13. The wall 14 of the sleeve body
13 comprises one or more, preferably four, longitudinal slots 15, which are provided
spatially spaced from one another in the sleeve body 13. The slots 15 extend over
a part of the lengths of the sleeve body 13. Material areas 16 between two adjacent
slots 15 are configured as tongues or straps. The sleeve body 13 comprises a first
end portion 17, which ends-up in a first end 17a, and which defines the head area
of the hollow sleeve body 13. An insertion opening 18 for receiving an expansion pin
is provided at the first end 17a. Furthermore, the hollow sleeve body 13 comprises
a sleeve head 19, which is provided at the first end 17a of the sleeve body 13, said
sleeve head 19 having a larger diameter and/or a larger cross-sectional area than
the hollow sleeve body 13. A fixation ring 41 is provided between sleeve body 13 and
sleeve head 19. The fixation ring 41, which has a guiding function as well, has an
outer diameter that is greater than the outer diameter of sleeve body 13, but which
is smaller than the outer diameter of sleeve head 19.
[0079] A second end portion 20 of the sleeve body 13, which ends-up in a second end 20a,
provides an exit opening 21 for the expansion pin 12, whereby the insertion opening
18 provided by the first end 17a of the sleeve body 13 and the exit opening 21 each
have the same diameter and/or the same cross-section. In order to increase the static
friction, at least one sawtooth-shaped arrangement 22 consisting of two or more clamping
teeth is provided which protrudes from an outer surface 23 of the sleeve body 13.
The hollow sleeve body 13 comprises a receiving space 24, which is bordered by the
wall 14 of the sleeve body 13. The receiving space 24 is provided for receiving the
elongated expansion pin 12. The expansion pin 12 is provided as a drive-in pin, that
gets pushed into the hollow sleeve body 13, when an impact force is exerted onto the
expansion pin 12. The expansion pin 12 comprises a first end portion 25, that ends-up
in a first end 25a, and a second end portion 26, which ends-up in a second end 26a,
said second end portion 26 being opposite to the first end portion 25. The first end
portion 25 comprises a head element 27 which is provided for receiving the impact
force, that can get exerted by means of a hammer or another suitable tool for example.
The head element 27 of the fastening device according to Figures 1 to 4 is configured
as a circular shaped head element 27.
[0080] The elongated expansion pin 12 comprises a longitudinal profile element 28, which
is provided as a cross-profile element. The cross-profile element comprises four legs
29, that intersect vertically and centrally. All legs 29 have the same length and/or
width. Each leg 29 has a first end 30 that is directed to respective first ends 30
of the other legs 29, whereby the four legs 29 are connected to each other via their
first ends 30 respectively. Furthermore, each leg 29 has a second end 31 opposite
to its first end, said second end 31 being a free end. A rib element 32 is provided
at each second end 31 of each leg 29. Therefore, the rib elements 32 protrude outwardly
from an outer surface of the longitudinal profile element 28. According to the embodiment
shown in Figures 1 to 4, the rib elements 32 are evenly distributed over the outer
perimeter of the elongated expansion pin 12. All rib elements 32, which is best shown
in Figures 2 and 3, have a triangular shape. In general, a triangle is a polygon with
three edges. With one of these edges the triangular rib element 32 is connected to
the longitudinal profile element 28 of the elongated expansion pin 12. Opposite to
this "connecting edge" the triangular shaped rib element 32 comprises a triangle-tip
33, said triangle-tip 33 being provided to get in contact with the inner surface of
the hollow sleeve body 13. Therefore, the area of the rib element 32 which comes in
contact with the hollow sleeve body 13 is very small. The length of the rib elements32
is shorter than the length of the longitudinal profile element 28. That means that
the rib elements 32 extend over a part of the length of the longitudinal profile element
28 only.
[0081] Figures 1 to 3 show the fastening device 10 in its initial state, when the expansion
pin 12 is still located outside the hollow sleeve body 13, whilst Figure 4 shows a
schematic representation, where the expansion pin 12 is inserted in the hollow sleeve
body 13.
[0082] In its initial state, and before the expansion pin 12 gets pushed inside the hollow
sleeve body 13 for its operational mode, the fastening device 10 is provided as one
single member, said fastening device 10 comprising the expansion sleeve 11 and the
expansion pin 12 being integral parts thereof. The elongated expansion pin 12 and
the sleeve body 13 are connected to one another via at least one material bridge 34.
This is shown in Figure 5. The material bridge 34 is provided as a film hinge or a
film gate. The material bridge 34 connects the second end 26a of the expansion pin
12 with the first end 17a of the hollow sleeve body 13. When the fastening device
10 is in its operational mode, the expansion pin 12 gets pushed into and then through
the receiving space 24 of the hollow sleeve body 13, whereby an impact force is exerted
onto the head area 27 of the expansion pin 12. By means of this impact force, the
material bridge 34 gets disrupted, such that the expansion pin 12 can move through
the hollow sleeve body 13.
[0083] A second embodiment of the fastening device 10 is depicted in Figures 7 to 10. The
basic configuration of the fastening device 10 is identical to the basic configuration
of the fastening device according to Figures 1 to 5. In particular, the configuration
of the expansion sleeve 11 is identical to the expansion sleeve 11 according to the
embodiment shown in Figures 1 to 5. Same applies to the basic configuration of expansion
pin 12 having a longitudinal profile element 28 including four legs 29, each leg having
a rib element 32 at its second free end. In order to avoid any repetitions, full reference
is therefore made to the description in connection with Figures 1 to 5. Furthermore,
identical components are denoted with identical reference numerals.
[0084] However, the head element 38 of expansion pin 11 and the sleeve head 19 show differences
in comparison to the embodiment shown in Figures 1 to 5. As can be seen from Figures
8a and 8b, the head element 30 of expansion pin 12 has the shape of a cross. The cross-shaped
head element 38 comprises a base area 39 being square or almost square in shape. The
four arms 40 of the cross are provided in each corner of the base area 39, and they
protrude from these corners to the outside beyond the base area 39. In this case the
insertion opening 18 of the sleeve body inside sleeve head 19 has a corresponding
cross shape. By use of such a head element 38 the expansion pin 12 can get easily
re-used. Furthermore, a better guiding and positioning of the expansion pin 12 inside
the hollow sleeve body can get realized. For that purpose, the insertion opening 18
has the same configuration as head element 38. Figures 7, 8a and 8b show the fastening
device 10 in its initial state, when the expansion pin 12 is still located outside
the hollow sleeve body 13, whilst Figure 8c shows a schematic representation, where
the expansion pin 12 is inserted in the hollow sleeve body 13.
[0085] Figures 9a and 9b depict a situation, where the different components of the fastening
device 10 according to the second embodiment are connected to each other by way of
a material bridge 34. As can be seen in Figures 9a and 9b, the second end portion
26 of the expansion pin 12 has an inclined, in particular a conically tapered, course,
which ends-up in the second end 26a of the expansion pin 12. The at least one material
bridge 34 is provided in the inclined course of the second end portion 26. By this,
positioning and guiding of the expansion pin 12 is increased, in particular if the
expansion pin is re-used.
[0086] As can be derived from Figure 10, the insertion opening 18 and the exit opening 21
of the sleeve body 13 are different in size and shape. The insertion opening 18 improves
guiding and positioning of the expansion pin 12. The exit opening 21 has the function
to release the expansion pin 12, if the fastening device 10 gets disassembled. Then
the expansion pin 12 gets pushed out of the sleeve body 13 via exit opening 21. Therefore,
it is advantageous if the exit opening 21 is as large as possible and if the cross-section
of the exit opening 21 is as simple as possible. In the embodiment shown in Figures
7 to 10, the exit opening 21 has a simple circular shape.
[0087] In its initial state, and before the expansion pin 12 gets pushed inside the hollow
sleeve body 13 for its operational mode, the fastening device 10 is provided as one
single member, said fastening device 10 comprising the expansion sleeve 11 and the
expansion pin 12 being integral parts thereof. The elongated expansion pin 12 and
the sleeve body 13 are connected to one another via at least one material bridge 34,
which is, in particular shown in Figures 9a, 9b and 10 as well.
[0088] Each rib element 32 in both embodiments shown in Figures 1 to 5 as well in Figures
7 to 10, is provided for exerting a pressure force on an inner surface 35 of the sleeve
body 13, when the expansion pin 12 gets inserted into the receiving space 24 of the
sleeve body 13 and pushed therethrough. This situation is shown in Figure 6. When
the expansion pin 12 is pushed through the hollow sleeve body 13, the rib elements
32 get in contact with the inner surface 35 of the hollow sleeve body 13. The rib
elements 32 press the hollow sleeve body 13, in particular the material areas 16 between
two adjacent slots 15 in the sleeve body 13, against a component surrounding the fastening
device 10, a receiving sleeve for example, which can be a handle tube 55 of a container
body as explained in connection with Figures 11 to 15 further below. The impact force
that is exerted on the expansion pin 12, is transferred to the hollow sleeve body
13 via the triangular rib elements 32 whereby the triangle tips 33 of the triangular
rib elements 32 are in contact with the inner surface 35 of the hollow sleeve body
32, whereby the triangular rib elements 32 press and/or cut and/or shear the hollow
sleeve body 13, in particular the wall 14 thereof. If the component surrounding the
elongated hollow sleeve body 13, is bigger, than the triangular rib elements 32 will
not cut so deep into the material of the hollow sleeve body 13, but will result in
a larger expansion of the sleeve body 13 due to the pressure force exerted on the
inner surface 35 of the sleeve body 13 by the rib elements 32.
[0089] Next, and in combination with Figures 11 to 15, the general function of the fastening
device 10 will be explained in detail at hand of a waste container 50. Figure 11 shows
the waste container 50 for temporarily storing waste and/or valuable substances. The
waste container 50 comprises a container body 51, which receives the waste and/or
the valuable substances. At its upper edge, the container body 51 comprises a receiving
opening (not shown), which is closed by a lid device 52. The lid device 52 is pivotably
attached to the container body 51 by means of at least one hinge device 53, preferably
by means of two hinge devices 53. The lid device 52 comprises two lid eyelets 54.
The hinge device 53 comprises a receiving sleeve for the fastening device 10, which
is provided as a handle tube 55 being associated to the container body 51.
[0090] Once the lid device 52 has been placed on the container body 51, in a first step,
as shown in Figure 12, the elongated hollow sleeve body 13 of the expansion sleeve
11 is guided through the lid eyelet 54 of the lid device 52, and is inserted and pushed
into the hinge sleeve of the container body 51, into the handle tube 55 in the present
case. The sleeve head 19 of the expansion sleeve body 13 prevents the sleeve body
13 from entirely sliding into the handle tube 55.
[0091] In a next step, which is shown in Figure 13, by exerting an impact force 36 onto
the head area 27, 38 of the expansion pin 12, by means of a hammer for example, the
elongated expansion pin 12 is pushed into the receiving space 24 of the hollow sleeve
body 13 via the insertion opening 18 that is provided by the first end 17 of the sleeve
body 13 (see Figures 1 to 5 or 7 to 10 for example). If the elongated expansion pin
12 and the hollow sleeve body 13 are connected to one another via a material bridge
34, the material bridge 34 gets destroyed due to the impact force 36 and both components
get separated from each other such that the expansion pin 12 can now freely move through
the hollow sleeve body 13. When the expansion pin 12 is pushed through the receiving
space of the sleeve body 13 into its "locking position", as shown in Figure 13, by
means of a push with a hammer or the like for example, the expansion pin 12 expands
the expansion sleeve 13 outwards in an expansion direction 37, under aid of the one
or more, preferably four, longitudinal slots 15, which are provided spatially spaced
from one another in the sleeve body 13. In particular, the material areas 16 between
two adjacent slots 15 get outwardly expanded, due to the rib elements 32, which protrude
outwardly from the outer surface of the longitudinal profile element 28 of the expansion
pin 12 (see Figures 1 to 10 as well). In particular, the triangular shaped rib elements
32 press the hollow sleeve body 13, in particular the material areas 16 between two
adjacent slots 15 in the sleeve body 13, against the inner wall of the handle tube
55, which is shown in Figure 14. The impact force that is exerted on the expansion
pin 12, is transferred to the hollow sleeve body 13 via the rib elements 32 whereby
the triangle tips 33 of the triangular rib elements 32 get in contact with the inner
surface 35 of the hollow sleeve body 13, whereby the triangular rib elements 32 press
and/or cut and/or shear the hollow sleeve body 13, in particular the wall 14 thereof
(see Figure 6 as well).
[0092] Finally, upon the expansion of the expansion sleeve 11, the expansion sleeve 11 gets
pressed against an inner wall of the handle tube 55, thus generating a form fit and/or
a force fit connection.
[0093] Disassembly, which is shown in Figure 15, works in a similar way. Then, the expansion
pin 11 must get pushed out of the hollow sleeve body 13 again. By exerting an impact
force on the head area 27,38 of the expansion pin 12, by means of a simple hammer
for example, the expansion pin 12 gets further pushed through the hollow sleeve body
13 and finally through the exit opening 21 of the hollow sleeve body 13, whereby the
expansion pin 12 can leave the receiving space 24 of hollow sleeve body 13 via the
exit opening 21. The expansion pin 12 can be received by and inside the handle tube
55, from where it can get easily removed, once the lid device 52 has been separated
from the container body 51.
