[0001] The present invention relates to a polygonal tightly surrounded object constructed
from flat, plate-like wall segments, which wall segments each possess two contact
sides opposite to each other, each contact side of a wall segment being positioned
with its side along substantially the entire length of the adjacent wall segment,
the contact sides forming straight edges of the polygonal surrounded object, and the
edges being positioned parallel to each other, defining a polygonal space, bordered
by the wall segments, with the body of wall segments being held together by a band
stretched around the wall segment's outer perimeter, and means being present to prevent
the wall segments from becoming displaced in relation to each other.
[0002] Such a surrounded object, in particular a container, is known from the American patent
specification US-A-1,775,224. This relates to a wooden container having very many
corners, which container is manufactured from a strip of interconnected rigid, plate-like
segments. The strip is provided with a groove to receive a bottom plate. The segments
are held together by means of hoops for which no groove is provided. To reinforce
the container, a flexible metal band is provided in a groove extending around the
perimeter of the container. Said patent publication mentions that said flexible band
is not expected to be able to protect the container against forces in longitudinal
direction.
[0003] The known container has various greater and lesser disadvantages. For instance, the
strength of the container depends to a relatively large degree on temperature and
atmospherical humidity. A change in these conditions may cause the wood to expand
at first and cause the metal band and/or the hoop to compress the wood in a manner
which may prove to be at any rate not quite reversible, with the result that after
the conditions change, the container is weaker than it was before under the same conditions.
Also, changing temperatures prevent the use of a metal band in combination with plastic
wall segments. When using metal bands, the place where the ends of the bands are mechanically
joined, is twice the thickness of the band used. A metal band is only flexible if
it is sufficiently thin, making it at the same time sharp, which may cause injuries,
for instance if the joint catches on a person. In addition, having colours other than
the colour of metal makes the bands, and consequently the container, relatively expensive.
[0004] The objective of the present invention is to provide a surrounded object of the kind
mentioned in the preamble from which said disadvantages have been eliminated.
[0005] To this end the surrounded object according to the invention is characterized in
that the means for the prevention of displacement of the wall segments in relation
to each other have been selected from:
i) a groove extending around the object's inside perimeter, which groove engages a
bottom plate; and/or
ii) a groove extending around the object's outside perimeter, into which groove the
stretched band is introduced, and the width of the groove substantially equals the
width of the stretched band; and the band is a flexible plastic band.
[0006] A flexible plastic band is by nature more elastic than a metal band. This makes the
container more resistant to ambient fluctuations. Also, the container may now be an
object such as a container with fewer edges. The thickness of a plastic band may help
to prevent displacement in the longitudinal direction as well as reduce the chance
of a user cutting himself on the flexible band. Finally, the objects can be placed
closer together because the band can be flushed completely. During transport, the
assembled and optionally filled objects take up less space than the assembled containers
disclosed in the American patent specification. Plastic bands are available in virtually
any colour, so that the appearance of the polygonal object may be further embellished.
[0007] The German patent publication DE-U-84 04 834 discloses a wooden container comprising
plate-like segments held together by means of a metal band. The segments comprise
around the inside perimeter a groove engaging a bottom plate. This publication does
not disclose the use of a flexible plastic band.
[0008] According to a favourable embodiment the flexible band is a thermoplastic plastic
band whose ends are fusion-joined.
[0009] Such a joint is not thicker than twice the thickness of the flexible band. In contrast
with the thermical joining of metal bands, the temperatures are so low that there
is no risk of the wall segments discolouring. Even when using plastic wall segments,
which in accordance with the present invention is also possible, there is no risk
of them melting.
[0010] The use of plastic band is generally known in the packaging industry, in particular
for sealing carton boxes, and makes it possible to manufacture objects such as containers
very inexpensively, while nevertheless being strong. Surprisingly, the strength suffices
also for light furniture such as chairs and small tables.
[0011] According to a favourable embodiment, the wall segments are provided at their outside
with a groove, whose depth is at least almost equal to the thickness of the flexible
band.
[0012] This prevents the plastic band from catching on something, as can happen with the
band according to the prior art. An additional advantage to be achieved is the saving
of space.
[0013] The present invention further relates to a method of manufacturing an object surrounded
by a band, which object comprises a bottom plate and wall segments.
[0014] The method according to the invention is characterized in that the wall segments
are placed in mutual contact against the bottom plate, the mutually contacting wall
segments being provided with means for prevention of displacement of the wall segments
in relation to each other, the means being a groove extending around the object's
inside perimeter, said groove engaging a bottom plate and/or a groove extending around
the object's outside perimeter, into which groove the band 3 is introduced,
around the wall segments at least one plastic band is applied, as plastic band a band
having two ends is used, and that the two ends are joined under a tensile stress.
[0015] It is relatively simple to automate this method. By using coloured plastic band,
one operation suffices to produce an object with a colourful band, which band is inexpensive
and whose colour does not flake off.
[0016] A second method, optionally to be combined with the method of manufacturing an object
surrounded by a band as described above, is characterized in that mutually contacting
wall segments are placed around and against a body serving as mould, which body conforms
to the shape and dimensions of the space of an object to be formed, that at least
one plastic band having two ends is applied around the wall segments, and that the
two ends are joined under a tensile stress, after which the body serving as mould
is removed from the thus formed space.
[0017] This manner makes it possible to quickly manufacture objects surrounded by a band
according to the invention which can be very light.
[0018] To each of the above-described methods of manufacturing a surrounded container applies
that preferably a thermoplastic plastic band is used and that joining occurs by supplying
heat.
[0019] An alternative to thermically joining is the use of a cable binder. This is a plastic
band having one jagged side. At a first end an opening is provided through which the
other end of the band can be drawn. Once drawn through, the end cannot be pulled back.
[0020] According to an alternative method for manufacturing an object surrounded by a band,
the wall segments are placed against an element defining the perimeter of the object
to be formed and, with the aid of an auxiliary device, an endless plastic band of
a length that in a state of rest is smaller than the circumference of the object to
be formed is placed around the wall segments at the intended place, after which the
element may be removed.
[0021] The element may be a bottom plate or a mould, the latter will naturally be removed
after manufacture of the object. The advantage of this method is that the object may
be supplied as a kit, taking up little space, and can be manufactured on site without
requiring any costly equipment. Conveniently, the auxiliary means is a tool comprising
a handle and a blade, which blade in the longitudinal direction is provided with a
V-shaped groove. The handle is attached to the end of the blade. The angle of the
V is larger than or identical with the angle of the polygonal object, so that it can
be used to stretch the plastic band without difficulty in order to guide it over the
wall segments and in particular over the edge formed by said wall segments.
[0022] Finally, the invention relates to a packing comprised of a lower element having standing
walls and an upper element having rims that are directed downward, so that when the
packing is closed, the rims of the upper element at least partially cover the walls
of the lower element.
[0023] The packing according to the invention is characterized in that the lower element
and the upper element have identical shapes, each comprising a surrounded container
according to the invention.
[0024] The invention will now be explained with reference to the drawing, in which
Fig. 1 shows a top view of a first embodiment of an object, in particular a container,
according to the invention;
Fig. 2 shows a side view of the container seen in Fig. 1;
Fig. 3 is a top view of a second embodiment of the container according to the invention;
and
Fig. 4 shows a cross section of the container shown in Fig. 3 according to line IV-IV.
[0025] The embodiment of a surrounded object according to the invention shown in Fig. 1,
is a surrounded container comprising a polygonal bottom plate 1 around which flat
plate-like wall segments 2a, b, c, d, e, f, g, h are placed. In the present application
the term flat means not curved. Each wall segment 2 possesses two contact sides opposite
to each other, which are in contact with an adjacent wall segment 2. The assembly
of bottom plate 1 and wall segments 2 is held together by means of a flexible plastic
band 3 stretched around the wall segment's 2 outer perimeter (Fig. 2).
[0026] Practically any flexible plastic may be used as plastic. The expert will, for instance,
use the plastic band commonly used for sealing carton boxes. The plastic band 3 is
chiefly made from polyester (which can be stretched 4-7% before breaking), polypropylene
(which can be stretched 10-12% before breaking), and advantageously foamed polypropylene
(which can be stretched 10-20% before breaking). Such a plastic band is generally
available and can be obtained, for example, from Compac GmbH, Elztal Dall, Germany.
[0027] The number of wall segments 2 of a container according to the invention may range
for instance, from three to twenty. The wall segments may be made from plastic or
wood, such as blockboard.
[0028] At their outside the wall segments are conveniently provided with a groove 4, whose
depth is adapted for the reception of the plastic band 3. If the container does not
have a groove extending around the inside of the perimeter, engaging a bottom plate
1, then the groove 4 extending around the outside of the perimeter is obligatory.
It is preferred that the thickness of the band 3 is equal to the depth of the groove
4. It is also preferred that the width of the band 3 is equal to the width of the
groove 4. This has a favourable influence on the strength of the surrounded container.
[0029] A suitable thickness for the wall segments is 3 to 25 mm, and preferably between
5 and 16 mm, this provides light and strong surrounded containers.
[0030] According to a preferred embodiment the grain of the wood runs in the circumferential
direction. Having the grain of the wooden wall segments run in the circumferential
direction, ensures that despite shrinkage and expansion of the wood due to changes
in temperature and humidity, the wall segments will remain under sufficient tension
to guarantee a strong container.
[0031] A surrounded container according to the invention may be symmetrical and may, for
instance, be formed from four to twelve wall segments. However, containers according
to the present invention may also be irregular polygons. According to a preferred
embodiment the wall segments 2 have substantially identical dimensions. Characteristically,
wall segments 2 have bevelled contact sides, with the bevel angle of two adjacent
wall segments being substantially identical. For a container having a symmetrically
octagonal bottom plate 1, said angle is 180°/8 =22.5°.
[0032] The surfaces where the wall segments meet, as shown in Fig. 3, are provided with
an axially extending groove 5 or an axially extending projection 6, which serve to
further strengthen the container for demanding purposes.
[0033] Fig 4 shows how a groove 7 extending around the inside of a surrounded container
engages the bottom plate 1. The thickness of the bottom plate 1 and the width of the
groove 7 are adapted to each other, that is to say they are almost identical, preventing
movement of the wall segments 2 in axial direction, thus guaranteeing a sturdy surrounded
container.
[0034] To manufacture a container surrounded by a band 3 according to the invention, the
mutually contacting wall segments 2 are placed against the bottom plate 1, and around
the outside of the wall segments 2 at least one band 3 is applied. The band 3 is preferably
a strip of plastic band having two ends, and the two ends are joined under a tensile
stress.
[0035] The required tensile strength depends on how strong the holder is required to be,
what kind of wood and plastic band 3 are used as well as its dimensions, and it lies
within the capabilities of the expert to determine said tensile strength by experimentation
without too much effort.
[0036] The plastic band is preferably a thermoplastic plastic band and is joined by supplying
heat. This technique is generally known, for instance from UK 1,531,082 relating to
the sealing of carton boxes and the holding together of products, and is surprisingly
very suitable for the manufacture of the surrounded container according to the invention.
According to another embodiment the ends may be joined with the aid of glue.
[0037] A preferred embodiment of the method according to the invention is characterized
in that wall segments are placed against a body serving as mould, which body conforms
to the shape and dimensions of the space of a container to be formed and a bottom
plate. The plastic band is applied and the body serving as mould is removed from the
space thus formed. The use of the mould facilitates the positioning of the wall segments
2 prior to their being surrounded by the band 3. They may also be held together temporarily
by a rubber (elastic) band.
[0038] Two containers according to the invention together may form a packing if the size
and shape of the first container are adapted to be inserted into the space of the
second surrounded container. Making the thickness, and preferably also the width of
the plastic band substantially identical to the depth (respectively the width) of
the groove will prevent the container catching on anything, as may happen with containers
according to the prior art.
[0039] The surrounded container and the packing according to the invention are suitable
as receptacle for a variety of products for which an elegant surrounded container
is required which is simple to manufacture. Said products may, for instance, include
chocolates and building blocks.
[0040] A surrounded container according to the invention can also be used as tray, coaster,
drawer, flower box, and as container for photographs, mirrors and jewellery. The surrounded
container according to the invention may also be provided with handles. In addition,
the surrounded object may further serve as base for other objects such as light furniture.
[0041] Finally, the invention also comprises container assemblies, that is to say products
comprising at least two surrounded containers according to the invention. Such container
assemblies can be used as furniture. Vertically placed containers do not require a
bottom plate. One or more wall segments will serve as base for the product to be received.
In this respect displays standing or hanging on a wall come to mind, for shops, wine
racks and book cases.
