Description

The present invention relates to a collapsible container which is a collapsible vase.
WO 2004/000528 discloses a plastic vase having a collapsible moulded container, a moulded rim, and a moulded base. The container has four walls with a membrane hinge running between adjacent walls. A pair of opposing walls of the container also has a membrane hinge running along the length of each wall dividing it into two halves. Each wall of the container also has a hinged flap at its base which folds inwards to form the base of the container. The moulded vase base has a raised rim inside of which the container is clipped. The moulded vase rim is clipped to the top of the container to hold it open.
A problem with this plastic vase is that when the vase has been erected by having the container has been clipped into its base and the rim clipped to the top of the container, the erected vase is not that stable as it can be easily knocked over. The vase is complex and not that cheap to make and it also has the problem of not being easily disposable.
JP 2006 326280 , on which the preamble of claim 1 is based, discloses a collapsible vase comprising a flower insertion part having an open state in which flowers can be placed in the insertion part and a flattened state for storage during non-use of the vase. The flower insertion part has four sides and a joint between each side enabling the flower insertion part to be collapsed to the flattened state. The flower insertion part has a pair of elongated outwardly extending parts with each part extending from one end of an alternate side of the flower insertion part. The vase has a base with a pair of slots for receiving the elongate outwardly extending parts when the flower insertion part is in its open state. Each outwardly extending part is inserted through a respective said slot and folded underneath the base. It is then folded upwards at the edge of the base and back towards the flower insertion part so that the distal end of the outwardly extending part can be held by a curved slot near the top of a side of the flower insertion part.
FR 2413273 discloses a packing container comprising a blank of sheet material that is then formed into a tubular body having a rectangular cross-section. Alternate sides of the tubular body have a flap at their base. The container has a base unit with a projecting flange on its perimeter. There is a pair of notches in the projecting flange for receiving respective flaps of the tubular body when the body is mounted on the base unit and a pair of recesses for receiving the respective flaps within the base unit when the flaps are received in the notches and folded underneath an upper portion of the base unit. The flaps are then fixed in the recesses by glue and a lid is placed on top of the tubular body. The flaps are therefore folded inwardly and the recesses for receiving the flaps are positioned directly beneath the tubular body.
It is an object of the present invention to provide a collapsible container to alleviate the above-mentioned problems.
According to the present invention there is provided a collapsible vase, comprising: a sleeve having a plurality of flaps extending from one end of the sleeve, the sleeve having an open state in which at least one item can be placed in the sleeve and a flattened state for storage during non-use of the vase; and a base having a plurality of slots for securely receiving said flaps when the sleeve is in its open state, there being the same number of slots as flaps with each flap being arranged to be inserted through a respective one of said slots and folded outwardly away from the sleeve, whereby the sleeve is retained by said base in its open state in a substantially upright position, characterized in that the underside of the base is formed with a respective recess aligned with each of said slots, each said recess being sized to receive the outwardly folded flap inserted through said slot.
A sleeve stabilising insert may be provided for insertion into the sleeve when the sleeve is in its open state.
The collapsible container may include a waterproof liner for the sleeve.
An embodiment of the present invention will now be described, by way of example, with reference to the accompanying schematic drawings, in which:

Figure 1 is an exploded view of a collapsible container in an open state according to an example which is outside the scope of the claimed invention;
Figure 2 is a sectional view of the collapsible container of Figure 1 in an open state;
Figure 3 is a perspective view of a waterproof liner for the container of Figure 1;
Figure 4 is a view of the bottom of the waterproof liner of Figure 3;
Figures 5 and 6 are views of the sleeve and sleeve holder, respectively, in a flattened state;
Figure 7 is an exploded perspective view of a collapsible container in an open state according to another embodiment of the invention; and
Figure 8 is an underside view of a base of the collapsible container of Figure 7.

Referring to Figure 1 of the accompanying drawings, a container in the form of a collapsible vase 1 is shown in its open state. The vase 1 has a sleeve 2 in which at least one item can be placed, a sleeve holder 3 or skirt, and a square base 4.
The sleeve 2 is a tube formed of four identical sides 5 with a joint 6 between each side 5 and the tube has a square cross-sectional area.
The sleeve holder 3 also has four identical sides 8 with a joint 9 between each side 8. Each side 8 has the configuration of a trapezium with the lower edges 10 of the trapeziums 8 bounding a square cross-sectional area at a base end 11 (see Fig. 2) of the sleeve holder 3 and the upper edges 12 of the trapeziums 8, which are shorter than the lower edges 10, bounding a square cross-sectional area forming an upper opening 13. Thus, the cross-sectional area of the sleeve holder 3 tapers between the base end 11 and the upper opening 13. The upper opening 13 is dimensioned to receive the sleeve 2 and the sleeve 2 is fitted within the sleeve holder 3 so that the sleeve 2 is held in an upright position and the sleeve 2 and sleeve holder 3 are coaxial about a central axis 14.
A trapezoidal flap 15 extends from each upper edge 12 and another trapezoidal flap 16 extends from each lower edge 10. The upper edge trapezoidal flaps 15 are all identical and the lower edge trapezoidal flaps 16 are also all identical. The upper edge trapezoidal flaps 15 are arranged to be against the sides 5 of the sleeve 2 and lower edge trapezoidal flaps 16 are arranged to be against an upper surface 17 of the base 4 with the distal edges 18 of the lower edge trapezoidal flaps 16 being coincident with the perimeter 19 of the base 4.
The upper edge trapezoidal flaps 15 is releasably fastened to the sleeve sides 5 by finger-lift adhesive 20 placed on portions of the sleeve sides 5 and split pin paper fasteners 21 are used to releasably fasten the lower edge trapezoidal flaps 16 to the base 4. Holes 22 are provided in the lower edge trapezoidal flaps 16 and the base 4 for the split pin paper fasteners 21. Split pin paper fasteners 21 may be used instead of the adhesive 20 to releasably fasten the upper edge trapezoidal flaps 15 to the sleeve sides 5. Any suitable arrangement of releasable fasteners may be used to fasten the upper edge trapezoidal flaps 15 to the sleeve sides 5 and the lower edge trapezoidal flaps 16 to the base 4 and these may include magnets, poppers or Velcro^RTM.
Referring to Figure 2, the vase 1 in its open state has the sleeve 2 inserted into the sleeve holder 3 so that the sleeve 2 rests on the base 4 and the sleeve 2 is held in an upright position by the sleeve holder 3. The sleeve holder 3 is fastened to the sleeve 2 by the finger-lift adhesive 20 and the sleeve holder 3 is fastened to the base 4 by the split pin paper fasteners 21 being passed through the holes 22 in the lower edge trapezoidal flaps 16 and the base 4. The end portions 23 of the fasteners 21 are then bent through 90 degrees to hold the flaps 16 and base 4 together.
Referring to Figure 3, a waterproof liner 24 for the vase 1 has a bag 25 and a supporting tube 26. The tube 26 is formed of four identical sides 27 with a joint 28 between each side 27 and the tube 26 has a square cross-sectional area which is slightly less than the square cross-sectional area bounded by the upper edges 12 of the trapeziums 8 of the sleeve holder 3. The bottom of each side 27 has a rectangular flap 29 (see Figure 4). The bag 25 is made from, say, a plastic, such as polythene, and the portion 30 of the bag around its entrance is folded over the top portion 31 of the tube 26 and is fixed to it by, say, staples 32. The remainder of the bag 25 hangs down inside the tube 26. The tube 26 can be in placed in a flattened state by having each tube side 27 pushed towards an adjacent tube side 27 so that they are coincident.
When the vase 1 is in its open state, the waterproof liner 24 is placed in an open state and one pair of flaps 29 of the tube 26 are folded towards each other and the other pair of flaps 29' are folded towards each other and overlap the flaps 29 in their corner regions. The flaps 29' are then held to the tube 26 by adhesive tape. The liner 24 is then placed into the sleeve 2.
When the vase 1 is not in use, both the sleeve 2 and the sleeve holder 3 can be collapsed to a flattened state for storage by means of their joints 6, 9. When the sleeve 2 is in its flattened state (see Figure 5), each sleeve side 5 is pushed towards an adjacent sleeve side so that they are coincident. When the sleeve holder 3 is in its flattened state (see Figure 6), each sleeve holder side 8 and its upper and lower trapezoidal edge flaps 15,16 are pushed towards an adjacent sleeve side and its upper and lower trapezoidal edge flaps so that they are coincident.
In a specific example of the example and modifications described above, the sleeve 2, sleeve holder 3 and base 4 comprise cardboard.
Figures 7 and 8 illustrate an embodiment of a collapsible vase 40 according to the invention. A flap 41 extends from the middle of the lower end of each side 42 of the sleeve 43. The base 44 has an upper square portion 45 placed centrally on a lower square portion 46 which extends beyond the upper square portion 45. The upper square portion 45 of the base 44 has slots 47 arranged to receive respective flaps 41 of the sleeve 43 when the sleeve 43 is in its opened state. The lower square portion 46 has a rectangular opening 48 corresponding to each slot 47 wherein each slot 47 is aligned with one side of the opening 48 and the opening 48 extends away from the slot towards the edge of the lower square portion 46. Each opening 48 is sized to receive a respective flap 41.
When the sleeve 43 is in its open state its flaps 41 are inserted into the slots 47 in the base 44. Each flap 41 is then folded underneath the upper square portion 45 of the base 44 and the flaps 41 fit within their respective openings 48 in the lower square portion 46 of the base 44.
A sleeve insert 49 is placed at the bottom of the sleeve 43 and is shaped so that it fits snugly within the sleeve 43.
A waterproof liner may then be inserted into the sleeve 43.
The sleeve 43, base 44 and sleeve insert 49 may comprise cardboard. The vase 40 described in the embodiment does not have a tapered sleeve holder 3 although such a sleeve holder could be included and the sleeve holder may provide aesthetic appeal. The base 44 extends sufficiently beyond the sleeve 43 when it is attached to the base to prevent the vase 40 being readily knocked over.
Whilst a particular embodiment has been described, it will be understood that various modifications may be made without departing from the scope of the claimed invention.
