[0001] The present invention relates to a cartridge and a connector, wherein the connector
can be sealingly inserted into and removed from an aperture of a head part of the
cartridge.
[0002] Cartridges filled with a material, such as for example a mastic material, are commonly
used in the industrial sector, such as for example in the construction industry or
in the transportation industry. Cartridges filled with components of a mastic medium
are frequently used to store the mastic materials and to dispense them for the respective
application as required. Examples for such a mastic medium are joint sealing compounds
or adhesives common for example in the construction sector. These cartridges are usually
produced from plastic and are manufactured in an injection molding process.
[0003] A distinction is made between single-component systems in which the material to be
dispensed is only made of one component and two-component or multicomponent systems
in which at least two different components are stored in separate chambers of the
same cartridge or in separate cartridges, wherein the multi-components are intimately
mixed on dispensing by means of a dynamic or static mixing apparatus.
[0004] Examples are two-component adhesives which only harden after the mixing of the two
components. Two-component systems are in particular also used in the industrial sector
for paints which are often used to generate functional protective layers such as for
corrosion protection. Other applications are found for oil and petroleum products
or for mastic asphalt concrete.
[0005] Cartridges filled with a medium are usually designed for a one-way use. Due to its
adhesive nature, the mastic medium for example will usually never be entirely dispensed
from the cartridge and residues will be left over within the cartridge. At present
it is therefore common practice to not refill cartridges. This causes considerable
waste.
[0006] For this reason, it is an object of the invention to create a cartridge for dispensing
a medium providing means to reduce a required storage space for storing the cartridges
as well to lower a carbon footprint.
[0007] This object is satisfied by a cartridge comprising a head part, said head part comprising
an aperture leading from an outer side of the head part to a cartridge chamber of
the cartridge. The cartridge chamber can be optionally filled with a material, as
for example a mastic medium. The cartridge further comprises a connector, with said
connector being sealingly insertable into and removable from the aperture. The connector
further optionally comprises a film extending over a surface of the connector with
said surface facing the cartridge chamber.
[0008] The connector can be a terminal connector. In other words, the terminal connector
only seals off the aperture of the head part when it is inserted into the aperture.
The connector can be removed for filling, i.e. single use applications, or refilling,
i.e. multi-use applications, the cartridge chamber with the medium through the aperture
of the head part. For this, the aperture of the head part can be configured as a filling
port of the cartridge.
[0009] Alternatively, the connector can be used for filling or refilling. In this case,
the connector can comprise an outlet having a passage arranged therein for connecting
the cartridge chamber to a further component, such as for example a filling mandrel
of a storage container or of a filling station for filling the cartridge chamber.
The connector can therefore provide a support for a filling process. The outlet of
the connector allows a precise positioning of the cartridge at the storage container
and/or filling station. Furthermore, the outlet can be designed to fit a specific
filling mandrel designed to refill the cartridge with a specific component or medium.
In this way, a risk for refilling the respective cartridge chamber of the cartridge
with another component as the component stored by the respective cartridge chamber
can be reduced.
[0010] The film can be a multi-layer film. This allows the use of different layers, with
each layer designed to particularly well bond with either the material of the connector
or the material of the head part of the cartridge. The film can extend over the complete
surface facing the cartridge chamber. In other words, the film can entirely cover
the aperture of the head part. The film can be configured to burst in the region of
the outlet of the connector on applying a dispensing pressure on the cartridge. The
film can therefore seal the outlet when arranging the connector for the first time
upon the aperture of the head part. Once the connector has been used as an outlet
for dispensing the medium or material of the cartridge chamber, the film bursts in
order to provide an aperture through which the medium can flow. Upon refilling, the
connector can be exchanged with another connector that comprises an intact film extending
over the complete surface facing the cartridge chamber.
[0011] Alternatively, the film can comprise an aperture in the region of an outlet from
said cartridge chamber. The outlet can be provided by the aperture of the head part
and/or the connector. The medium can freely flow through the aperture of the film.
[0012] The cartridge can be one of a film bag cartridge and a solid cartridge. If a film
bag cartridge is used this can be either pre-collapsed for filling or inflated for
filling. Regardless of whether a film bag cartridge or a solid cartridge is used,
said cartridge can be a single component cartridge or a multi-component cartridge.
Said cartridge can be one of a side by side cartridge, a click together cartridge
or a coaxial cartridge.
[0013] The cartridge may be designed to be re-used respectively the cartridge chamber may
be designed to be refilled with a respective medium or component at least for a second
time. Such a refillable cartridge provides a plethora of new storage options. For
example, a reduced number of cartridges will be brought to remote locations while
storing most of the material component in one or more large containers or tanks at
said remote location. With this, a total weight and the space taken up by the rigidly
formed cartridge chambers can be lowered. As a result, a storage space can be optimized
to comprise as much material component as possible and/or to weigh as little as possible,
which is particularly favorable in confined locations such as on construction sites,
on oil platforms, on ships and/or on airplanes.
[0014] When transporting a certain amount of the material component, a weight required to
be transported including the weight of the cartridges is equally reduced as fewer
cartridges are needed. Therefore, the invention provides the further advantage of
providing a possibility to reduce a carbon footprint for transporting material components
and their respective cartridges.
[0015] This is particularly beneficial when using for example mastic materials in remote
locations, such as construction sites or offshore platforms, where a particularly
high number of mastic cartridges have to be stored on site using up a lot of a limited
and much needed storage space. Furthermore, in the context of environmental protection,
the avoidance of a one-way usage of a high number of plastic cartridges is particularly
beneficial.
[0016] In this connection it should be noted that a mastic material is generally regarded
as a material that either on its own or through the addition of a hardener solidifies
on use of the respective material to form a bond at or between components. The cartridge
chamber may be filled with a material, for example, with a material selected from
the group of members consisting of topical medications, medical fluids, wound care
fluids, cosmetic and/or skin care preparations, dental fluids, veterinary fluids,
adhesive fluids, disinfectant fluids, protective fluids, paints and combinations of
the foregoing. For example, the material comprises silicon, 2K adhesives or a mold
material.
[0017] Preferably, the aperture is separate from an outlet of the cartridge. In other words,
the cartridge further comprises an outlet for dispensing a medium respectively a material
component, with the outlet being different from the aperture.
[0018] For example, the head part of the cartridge can further comprise such a dispensing
outlet. A cartridge chamber of the cartridge is therefore designed to be filled respectively
refilled with the medium via the aperture, wherein the medium is dispensed via the
separate outlet. This is in particular advantageous for a two-component cartridge
with two chambers filled with different components, wherein each component of the
cartridge is dispensed via the same dispensing outlet. In order to reduce a risk of
a premature combining or mixing of the two components upon refilling, each cartridge
chamber is filled via its own aperture that is different from the common dispensing
outlet.
[0019] Alternatively, the connector comprises an outlet from the cartridge, the outlet having
a passage arranged therein for connecting the cartridge chamber to a further component.
For example, for a two-component cartridge, the connector can comprise a common outlet
for both components of the cartridge. Alternatively, each cartridge chamber can comprise
a connector, wherein the two connectors of the two-component cartridge form a common
outlet for the cartridge.
[0020] Preferably, at least one of the connector and the aperture comprises a valve. The
valve can be arranged within the passage of the outlet. The valve can be removable
from said aperture. The valve can be designed for regulating and/or directing a flow
of the material component or medium when filling the cartridge chamber via the connector
respectively via the aperture.
[0021] Preferably, the connector is sealingly inserted within the cartridge head by means
of at least one of a screwed connection, a bayonet type of connection, a plug and
rotate type of connection, an adhesive bond, a thermal welding bond, an ultrasonically
welded bond, a press and/or interference fit, and a snap in connection.
[0022] Preferably, the aperture of the head part comprises an inner thread and the connector
comprises an outer thread mating with said inner thread of said aperture. The connector
can be designed to be screwed into the aperture of the cartridge head part via the
corresponding outer and inner threads. This allows a stable connection between the
head part of the cartridge and the connector, such that the aperture can be safely
closed by the connector.
[0023] Preferably, a seal is arranged between the head part and the connector. In particular,
said seal can be arranged between the aperture and the connector and/or at said connector.
The seal allows to avoid an uncontrolled and/or undesired leaking of the medium or
component comprised within the cartridge chamber.
[0024] Preferably, the connector comprises a second thread at a side of the connector disposed
opposite to the outer thread. Preferably, a diameter of the second thread differs
from a diameter of said outer thread. Preferably, said second thread is one of an
inner thread and an outer thread. The second thread can be designed to be mated with
a further thread, such as for example a thread of a filling mandrel of a filling station.
Upon filling the cartridge chamber, a tight and secure connection can be realized
between the filling mandrel and the cartridge chamber via the connector.
[0025] Preferably, when the cartridge is designed as a multi-component cartridge, said multi-component
cartridge comprises one of a combined outlet comprising two outlets formed by a common
connector installed in two separate apertures and two separate outlets with each outlet
being formed by a separate connector installed in a separate aperture and with the
separate outlets being combinable to form a common outlet. The different components
of the cartridge can be therefore mixed and/or be combined when they are dispensed
simultaneously via the common outlet. However, the separate apertures allow each chamber
of the multi-component cartridge to be filled or refilled separately from the other
chamber, such that an undesired mixing or bonding of the different components can
be avoided upon re-filling.
[0026] Preferably, the cartridge comprises a further aperture configured as a filling port
in said cartridge chamber and said filling port being able to be closed off in a releasable
and sealing manner via a and/or said terminal connector. Said terminal connector can
comprise a film extending over a surface facing said cartridge chamber.
[0027] Preferably, on installing said two separate connectors in the two separate outlets
the two connectors are axially moved in the direction of the respective outlet and/or
are rotated into the position in which they form the common outlet.
[0028] Preferably, the separate connectors are connectable to one another via at least one
of a snap fit, interference fit, press fit, a mixer connectable to the common outlet,
a bayonet type connection, and a ring attachable to the common outlet. The connection
between the two connectors allows a stable formation of a common outlet and hinders
the two connectors to disengage from each other, for example due to applying a dispensing
pressure on the cartridge.
[0029] According to another aspect the present invention relates to a connector for a cartridge,
with said connector being sealingly insertable into and removable from an aperture
of a head part of the cartridge. The connector optionally further comprises a film
extending over a surface of the connector with said surface facing a cartridge chamber
of the cartridge when connected to the cartridge.
[0030] The advantages associated with the cartridge likewise hold true for the corresponding
features of the connector.

[0032] In the in the following the same reference numerals will be used for parts having
the same or equivalent function. Any statements made having regard to the direction
of a component are made relative to the position shown in the drawing and can naturally
vary in the actual position of the application.
[0033] Fig. 1 shows an example for a two-component cartridge 1. The cartridge 1 comprises
two generally cylindrical cartridge chambers 2, 3. The cartridge chambers 2, 3 are
each bound by a cartridge wall 4, 5 as well as by a head part 6, 7, with each head
part 6, 7 being arranged at a respective front end 8, 9 of the cartridge wall 4, 5.
Each cartridge wall 4, 5 extends in a longitudinal direction A of the cartridge 1
from a respective rear end 10, 11 to the respective front end 8, 9.
[0034] Each head part 6, 7 is a stable shaped part of generally plate-like shape, which
comprises a common dispensing outlet 12 via which a medium (not shown) can be dispensed
from the cartridge chambers 2, 3. For this, the two components of the medium stored
within the chambers 2, 3 mix or combine at the dispensing outlet 12 before being released
outwardly as a combined medium from a common outlet part 14 of the dispensing outlet
12. The dispensing outlet 12 extends from the head parts 6, 7 as an outlet passage
through the common outlet part 14. A mixing tip (not shown) or closure part 13 can
be connected to the outlet part 14.
[0035] Each head part 6, 7 has a collar 17, 18. A radial direction B is indicated relative
to the arrow A used to identify the longitudinal direction A. Each collar 17, 18 has
a length extending in the longitudinal direction A. The front end 8, 9 of each cartridge
wall 4, 5 is sealingly and non-releasably connected to the collar 17, 18 of the head
part 6, 7.
[0036] It should be noted that the cartridge 1 can also be configured as a one-component
cartridge (not shown), comprising only one generally cylindrical cartridge chamber
with a single head part and a film forming the cartridge wall. In the following, corresponding
features of the one-component cartridge and corresponding features of the two-component
cartridge 1 mutually hold true.
[0037] The cartridge chambers 2, 3 are configured to be refillable with their respective
component of the medium. For this, the cartridge 1 comprises a connector 40 or respectively
two connectors 40 as shown in fig. 2. In particular, the cartridge chambers 2, 3 can
be refilled five or more times. When refilling the chambers 2, 3 of the two-component
cartridge 1, care has to be taken in order to not accidentally refill a chamber 2,
3 with another medium component than the one that has been previously been contained
by the respective chamber 2, 3. For example, a mastic medium is particularly adhesive,
a chamber 2, 3 will most likely never be entirely emptied out of the mastic medium
component. A mixing of different components within the chambers 2, 3 is therefore
to be avoided.
[0038] The connector 40 shown in fig. 2 is designed for a cartridge, as for example for
the cartridge 1. The connector 40 is designed to be connected to an aperture 43 of
a head part 6 of the cartridge 1 that is for example not formed by the dispensing
outlet 12 of the cartridge 1 shown by fig. 1.
[0039] The connector 40 comprises an outlet 42 having a passage arranged therein for connecting
a cartridge chamber 2, 3 to a further component. When the connector 40 is connected
to the cartridge head part 6, 7, the outlet 42 can correspond to an outlet of the
respective cartridge chamber 2, 3 through which the medium component stored within
the respective cartridge chamber 2, 3 is to be dispensed. The connector further comprises
at least one inlet 44 through which the medium component that is to be dispensed from
the cartridge chamber 2, 3 passes through.
[0040] The connector 40 further comprises an outer thread or a male thread 46 which is designed
to be sealingly inserted within the aperture 43 of the cartridge 1 or one of the cartridge
head parts 6, 7. The aperture 43 of the head part 6, 7 of the cartridge 1 comprises
an inner thread or female thread 48 which is mating with the outer thread or male
thread 46 of the connector 40. In other words, the connector 40 is designed to be
screwed into the aperture 43 of the cartridge head part 6, 7 via corresponding male
and female threads 46, 48. For this, an outer diameter of a cylindrically shaped male
thread 46 can be chosen to correspond to an inner diameter of a cylindrically shaped
aperture 43 with the female thread 48. The connector 40 further comprises a second
thread 49 designed to be mated with a further thread, such as for example a thread
of a filling mandrel of a storage container and/or of a filling station.
[0041] Alternatively to the connection formed by the male thread 46 and the female thread
48, the connector can form with the aperture 43 of the cartridge head part 6, 7 a
screwed connection, a bayonet type of connection, a plug and rotate type of connection,
an adhesive bond, a thermal welding bond, an ultrasonically welded bond, a press and/or
interference fit, and/or a snap in connection.
[0042] The connector can be used for or alternatively be removed when refilling the respective
cartridge chamber 4, 5. A filling can then occur via the outlet 42 or directly via
the aperture 43. The use of such a connector 40 on filling can aid in avoiding a cross
contamination between the one or more outlets from the cartridge 1 further ensuring
the lifetime of the cartridge 1.
[0043] Fig. 3 schematically shows the head parts 6, 7 with the common dispensing outlet
12 of the cartridge 1 as described for fig. 1. Each head part 6, 7 comprises a filling
connector port 50, 52 designed to provide a connection interface to connect the connector
40 to a respective cartridge chamber 2, 3 of the cartridge 1 via the filling connector
ports 50, 52. For example, each filling connector port 50, 52 is designed as an aperture,
as for example the aperture 43 shown by fig. 2.
[0044] The cartridge 1 can comprise in total two connectors 40 as shown in fig. 2. Each
cartridge chamber 2, 3 is filled with a medium respectively component via the connectors
40. The connectors 40 therefore provide a support for a filling process. For example,
the outlet 42 connects to a storage container filled with the medium component to
be filled into the cartridge chamber 6.
[0045] When it is determined that a connector 40 respectively its outlet 42 has spanned
its lifetime, for example because too much residue of the medium component has accumulated
within a valve of the connector 40 or the outlet 42, the connector 40 can be simply
replaced without having to replace the entire cartridge head part 6, 7 respectively
cartridge 1.
[0046] Alternatively the connector can be a terminal connector that is insertable into the
connector ports 50, 52 once the connectors 40 have been removed after their purpose
of filling or re-filling the cartridge. The terminal connectors then typically comprise
a film at a surface facing into the cartridge chamber 2, 3 in order to ensure a sufficient
storage life of materials stored in the cartridge chambers 2, 3.
[0047] Figs. 4a, 5a and 6a schematically show further embodiments of the connector 40, wherein
figs. 4b, 5b and 6b show an exploded-view of the respective connector 40 shown by
figs. 4a, 5a and 6a. An outlet 42 of the connector 40 can be closed (shown in fig.
4a) or opened (shown in figs. 5a and 6a). In order for the medium respectively component
stored with the cartridge chamber 2, 3 to not leak or flow outwards, the outlet 42
of the connector 40, a film 54 is arranged between the connector 40 and the aperture
43 of the head part 6, 7 of the cartridge 1.
[0048] In the example shown by figs. 4a and 4b, the film 54 comprises an aperture 56, since
the outlet 42 is closed. When refilling the cartridge 40 via the closed outlet 42
shown in figs. 4a and 4b, the outlet 42 can be designed to burst upon positioning
the filling mandrel on the outlet 42, for example.
[0049] The outlet 42 of the connector 40 shown by figs. 5a and 5b is opened, i. e. the medium
can freely flow through. In order to prevent this, the film 54 is entirely closed,
i.e. a surface of the film 54 completely covers the aperture 43 of the head part 6,
7 of the cartridge 1.
[0050] When refilling the cartridge 1 via the outlet 42, the film 54 is designed to burst
when positioning the filling mandrel on the outlet 42, for example. In addition or
alternatively, if the outlet 42 is designed as a dispensing outlet, the film 54 is
designed to burst upon applying a dispensing pressure, such that the medium or component
can freely flow through, alternatively the film 45 can be designed to be pierced by
a component or to be opened in a different way, such as by a film removable by hand.
[0051] The outlet 42 of the connector 40 shown by figs. 6a and 6b is opened and the film
54 comprises an aperture 56. In order to avoid a leaking of the medium or component,
the connector 40 further comprises a cap 58 designed to be arranged on the outlet
42. In contrast, the two embodiments of the connector 40 shown by figs. 4a, 4b, 5a,
5b do not require a cap 58 in order to avoid a leaking.
[0052] Figs. 7, 8 and 9 show from a perspective, top and cross-sectional view respectively
a two-component cartridge 1' that, unlike the cartridge 1 shown by figs. 1 and 3,
does not comprise a separate outlet 14. Instead, the head parts 6, 7 of the cartridge
1' each comprise an aperture 43 on which a respective connector 40 is to be arranged.
For example, each connector 40 can be screwed separately onto the aperture 43 of the
head part as shown by fig. 2.
[0053] When arranged at the apertures 43, the two connectors 40 form a snap fit connection
with each other. Alternatively, the two connectors 40 can form for example an interference
fit or a press fit or a bayonet type connection. In other words, the two connectors
40 are designed to snap into each other. For this, the two connectors 40 can comprise
complementary shapes, as shown for example by fig. 8. The complementary shapes can
intertwine respectively interlock together to form a combined connector. The combined
connector can form a common dispensing outlet 60 for the two cartridge chambers 2,
3 that is provided by the two outlets 42 of the connectors 40.
[0054] As shown by fig. 9, each connector 40 comprises a film 54 that extends over the entire
radial surface of the aperture 43 of a respective cartridge chamber 2, 3. The outlets
42 of the two connectors 40 are therefore sealed against the medium contained by the
cartridge chamber 2, 3. When dispensing the medium for the first time, the film 54
is configured to burst in the region covering the outlet 42 on applying a dispensing
pressure on the cartridge 1'. Alternatively, the connector 40 can comprise a film
54 with an aperture 56 in the region of the outlet 42 as shown by figs. 4b and 6b.
Furthermore, a valve (not shown) can be arranged within the outlet 42 in order to
regulate or direct a flow of the component or medium comprised by the cartridge chamber
2, 3.
[0055] Figs. 10, 11 and 12 show further possible variants of the two connectors 40 forming
a snap fit as the two connectors 40 shown in figs. 8 and 9. As shown by fig. 10, the
shapes of the two connectors 40, as shown here for example from a top view, can be
any given as long as the two shapes are complimentary. The two shapes can therefore
resemble two puzzle pieces. In addition, as shown by fig. 11, the two connectors 40
can comprise the same shape, with the two shapes engaging with each other. Moreover,
the shapes engaging with each other can at least partially be formed along a radial
surface of the connectors 40. As shown by fig. 12 in a cross-sectional view, the radial
surface of each connector 40 comprises a protrusion 62 respectively a snap-in nose,
wherein the two protrusions 62 of the two connectors 40 are arranged such that the
two protrusions 62 face each other when the two connectors 40 are arranged on the
apertures 43 of the cartridge 1'. Further, the two protrusions 62 are positioned on
different heights along a longitudinal direction A of the connectors 40. In this way,
the two protrusions 62 can engage with each other and hinder the two connectors 40
from disengaging when the two connectors 40 are installed on the apertures 43 of the
head part 6, 7 of the cartridge 1'. Alternatively, one of the two connectors 40 can
comprise a groove and the other connector 40 can comprise a protrusion designed to
be received by the groove.
