COLLAPSIBLE CONTAINER

Field of the invention

The present invention relates to collapsible containers; In particular, but not exclusively, the invention relates to a collapsible container including features which enhance rigidity of the container when expanded and yet do not hinder the container bemg collapsed into a relatively small volume. Moreover, the mvcnton also relates to a method of increasing the rigidity of collapsible containers without substantially impairing their ability to be folded to a relatively compact volume.

Background to the invention

Collapsible containers are known. For example, in a United Kingdom patent apphcation no. GB 2, 367, 283, there is described a collapsible container, for example suitable for holding refuse sacks, comprising a front panel, a rear panel, a first side panel, a second side panel, a base panel and a kid. The rear panel and the front panel are mutual attached by way of the side panels and the base panel so as to be capable of provdmg a substantially rectangular-form enclosure when In spaced-apart expanded configuration. I he hd Is coupled by way of a pvotable hinge to the rear panel. In an expanded configuration, each of the side panels assumes a form of a generally planar element. The side panels and the base panel are designed to be collapsible, for example by way of Inclusion of lmear hmges therein, so that the container can be rendered substantially flat where the front and rear panels are moved mutually spatially close; moreover, when the container Is m a collapsed state, the lid folds over the front panel at an exterior face thereof to cover it. In use, the rear panel Is preferably fixed to a secure structure, for example a wall or fence, to prevent unwanted movement of the container and to maintain m an upright position when not in use when m its collapsed condition.

The Inventors have appreciated that the collapsible container described in the foregoing patent apphcahon Is insufficiently rigid for many practical apphcations such that the use of thicker materials for constructing the container Is not In Itself sufficient to Impart adequate rigidity.

Thus, the Inventors have devised a modified form of collapsible container which is capable of addressing rigidity problems associated with the inventor's present known collapsible container described in the aforesaid patent apphcaton.

Beneficially, the locking means Is also arranged to secure the container in its collapsed configuration; such an arrangement enables the lockmg means to perform a dual function in expanded and collapsed configurations of the container.

The Inventors have appreciated that the container Is susceptible to being manufactured from a wide range of materials. For example, to satisfy certain market tastes where only organic and/or recyclable materials are acceptable, the container can be fabricated from materials such as wood, ; leather, natural-fibre and cloth. Alternatively, especially where inexpensive manufacture and/or maximum durability are Important, synthetic man-made materials can be alternatively or additionally employed to fabricate the container. Thus, preferably, the container Is fabricated from at least one of: plastics materials, wood, leather, imitation leather, metal, woven fabric, I expanded flexible plastics material foam, wood board composite, mineral glass composite, carbon fibre composite and wire mesh.

Description of embodiments of the invention

Referring to Figure 1, there is shown a collapsible container according to the invention, the container indicated generally by 10. The container 10 comprises a lid 20 with associated peripheral hp 40 as Illustrated coupled via a flexible pivotal hinge 30 to a rear panel 50 of the container 10. The container 10 further comprises a front panel 60, the rear and front panels 50, respectively being coupled together by way of first and second left-hand side panels 70a, 70b, first and second right- hand side panels 80a, 80b and first and second bottom panels 90a, 90b also as Illustrated. The front and rear panels 60, 50 are preferably relatively rigid planar components; optionally, they are fabricated from a plurality of material layers affixed together by one or more of sewing, gluing, riveting and welding. Triangular regions 85a, 85b of flexible material are Included to assist the contained fold to its compact folded configurtibon.

The first left-hand side panel 70a Is connected between a peripheral side edge of the rear panel 50 and a pivotal hinge 150a. Similarly, the second left-hand side panel 70b is connected between the hinge 150a and the peripheral side edge of the front panel 60; the hinge 150a is disposed substantially parallel to the peripheral side edges whereat the side panels 70a, 70b are attached to the rear and front panels 50, 60 respectively. Upper edges of the left-hand side panels 70a, 70b are reinforced to enhance their rigidity, for example by including plastics material such a t extruded glass fibre rods or metal rods therein, relative to other regions of the side panels 70a, I 70b. However, such rigidity reinforcement features 100 are not arranged to traverse the hinge 150a, namely each left-had side panel 70a, 70b includes the reinforcement feature substantially along an extent of its upper edge. A shdablyengaged elongate collar 120 retained over the c - 8 . . 8 8 À 8 8 reinforcement features 100 is also included so that the left- hand side panels 70a, 70b are maintained in substantially mutual planar configuration when the collar 120 is slid over the hinge 150a at the upper edges of the left-hand side panels 70a, 70b. Similar considerations pertain also the right-hand side panels 80a, 80b with respect to their associated hmge 150b.

In inset mdcated by 200, the collar 120 is Illustrated engaging over the hinge 150a to overlap both left-hand side panels 70a, 70b at reinforcement features 100 thereof to maintain the panels 70a, 70b in rigid spatial configuration when the container 10 Is in a deployed expanded configuration. Conversely, in mset Indicated by 210, the collar 120 Is Illustrated slid onto the; upper edge of the second left-hand side panel 70b over its reinforcement feature 100 so that it no longer traverses the hinge l50a and first left-hand side panel 70a so that the side panels 70a, 70b can readily pivot together as Illustrated to enable the container 10 to retam its folded configuration. Similar considerations pertam to the right-hand side panels 80a, 80b and their associated reinforcement features 100, their collar 120 and their hinge 150b. The collar 120 is preferably fabricated from a flexible extruded plastics material, for example polypropylene, nylon or polyethylene.

The container 10 Is susceptible to being configured from its expanded configuration to its folded configuration by applying mechamcal force to cause the hinges 140, 150a, 150b to move spatially towards one another. Conversely, the container 10 Is susceptible to bemg configured from its folded configuration to its expanded configuration by applying mechamcal force to cause the hinges 140, l50a, 150b to move spatially apart from one another.

Enhancing rigidity at an upper peripheral region of the container 10, namely along upper peripheral edges of the front and rear panels 60, 50 and side panels 70a, 70b, 80a, 80b is found by the Inventors to be especially beneficial in rendering the container 10 practical in use when housing Items of sgmficant weight.

Preferably, the container 10 is fabricated as a unitary component. Alternatively, it Is susceptible to bemg fabricated from a plurality of individual components which are one or more of sewn, t riveted, thermally welded and adhesively bonded together. At least one of the panels 50, 60, 70a, 70b, 80a, 80b, 90a, 90b Is preferably optionally fabricated from a plurality of layers. More preferably, the panels 50, 60, 70a, 70b, 80a, 80b, 90a, 90b include plastics material sheet, for example substantially I mm thick PVC sheet, which are not only easily stamped out to provide e. :: #:e... À:e panel components for constructing the container 10 but also easily sewn together. Alternatively, the panels 50, 60, 70a, 70b, 80a, 80b, 90a, 90b can include thin metal sheet, for example 1 mm thick aluminium sheet, to provide enhanced panel rigidity. Outwardly-facing surfaces of the container 10 are beneficially implemented in one or more of woven cloth, imitation plastics material leather, real leather, plastics matenal film and such hke.

The container 10 optionally includes locking features 280, 290, for example repositionable Velcro strip, for enabling the lid 20 to be securely fastened to the front panel 60 when the lid 20 Is positioned to close the container 10 when m an expanded configuration. Alternatively, or additionally, the container 10 Is susceptible to being provided with a zip fastener along a peripheral edge of the lip 40 of the lid 20 so that the lid 20 can be secured along its length to one or more of the front and rear panels 60, 50 respectively and the side panels 70a. 70b, 80a, 80b; advantageously, the zip is also operable to secure the lid 20 when the container 10 Is in one or more of collapsed and expanded configuration.

Preferably, especially where the container 10 is used in outdoor environments, when the Ed 20 is in a closed position to engage the loclang features together, an upper outer surface of the lid 10 Is sloping, namely non-orthogonal to the front and rear faces 60, 50 so that rain water does not have a tendency to collect on the lid 20.

The rear panel 50 Is also beneficially provided with hanging features, for example a hook, to enable the container 10 to be attached to walls, posts and similar substantially vertically-dsposed surfaces.

The container 10 of Figure 1 potentially suffers a drawback m that the bottom panels 90a, 90b can bow somewhat when heavy items are placed m the container 10. In this respect, the inventors have devised an Improved version of the container 10 wherein the bottom panels 90a, 90b are fashioned as illustrated m Figure 2.

In figure 2, in a vicinity of the bottom hinge 140, the bottom panels 90a' 90b are provided with alternating overlapping inwardly-facing tongue- like extensions 350a, 350b as illustrated. The extensions 350a derive from the second bottom panel 90b, whereas the extensions 350b derive from the first bottom panel 90a. When the bottom panels 90a, 90b are configured m their deployed expanded configuration whereat they are substantially parallel and their extensions - 10 À À . À À À . . À . . 350b, 350a respectively abut onto inwardly facmg surfaces of the bottom panels 90a, 90b, the bottom region of the container 10 is rendered highly nod when in an expanded deployed configuration; such an arrangement is indicated generally by 300. When the container 10 Is in a folded state, planes of the extensions 350a, 350b approach being mutually parallel as indicated generally by 400. The extensions 350a, 350 preferably protrude a distance "d" which is In a range of 25% to 75 % of a basic width "e" of each bottom panel 90a, 90b.

In Figure 3, there is shown an additional or alternative manner in which the bottom region of the collapsible container 10 can be rendered more rigid when the container 10 Is m an expanded configuration. There Is additionally Included a nudity panel 510 pivotally attached by way of a hinge to a lower peripheral edge of the rear panel 50. Alternatively, the rigidity panel 510 can be pivotally attached to the front panel 60. The rigidity panel 510 preferably has a width "b" which Is beneficially in a range 70% to 95% of a combined bottom panel width of "2e". When the container 10 Is m its folded configuration, the rigidly panel 510 Is pivoted so as to lie substantially parallel to the front and rear panels 60, 50, thereby enabhng the hinge 140 to move Inwardly to enable the bottom panels 90a, 90b also to lie substantially parallel to the front and rear panels 60, 50 as shown Indicated generally by 520.

It will be appreciated that the arrangement of extensions 350a, 350b Illustrated m Figure 2 can be optionally combined with inclusion of the rigidity panel 510 to achieve an especially rigidity enhanced bottom region of the container 10 when deployed in an expanded configuration, and yet not dmmsh the capability of the container 10 to be folded to its compact collapsed configuration.

The inventors have also appreciated that the rigidity flap 510 can also be incorporated as a rigidity enhancing feature to the side panels 70a, 70b, 80a, 80b as illustrated in Figure 4. In Figure 4, a rigidity panel 620 pivotally attached by way of a hinge 620 to the rear panel 50 Is included as illustrated wthm the container 10 to abut onto, In mutually substantially parallel configuration, the left-hand side panels 70a, 70b. Similar provisions pertam to a rigidity panel for the nght-hand side panels 80a, 80b. The ngdty panel 620 is pivoted to he substantially parallel to the front and rear panels 60, 50 as indicated generally by 650 when the container 10 Is in its folded collapsed configuration. - 11

: À. t: :: t' À : : : : À . . . It will be appreciated that the rigidity panel 620 can be included as an alternative or an addition to the collar 120 for enhancing rigidity. For enhanced rigidity, the collar 120 and the rigidity panel 620 are both included In the container 10.

In a similar manner to Figure 2 wherein alternate nwardly-facmg alternate extensions 350a, 350b to the bottom panels 90b, 90a are included to enhance rigidity of the bottom region of the container 10, the side panels 70a, 70b, 80a, 80b can also be provided with such extension features to enhance their ngdty when in an expanded configuration.

In order to yet further increase rigidity of the container 10 and yet not significantly enhance its weight and manufacturing cost whilst still enabling the container 10 to be folded to a collapsed I configuration, lateral edges of the front and rear panels 60, 50,whereat they are coupled to their associated side panels 70b, 80b, 70a, 80b respectively, can be provided with elongate strengthening struts, for example fabricated from metal rod and/or extruded glass-fibre rod, so as to render the container 10 less susceptible to collapse when a downward force is applied to an upper peripheral edge of the container when in an expanded configuration. The Inclusion of such strengthening struts does not impair the ability of the container 10 to be folded to its collapsed configuration.

It will be appreciated that increasing rigidity of the container 10 in its expanded configuration enables it to be employed m applications whichwould be Impracticable for the collapsible I container described In the aforementioned patent application above. Such enhanced rigidity enables stacking of a plurahty of the containers 10 as well as apphcatons where the container 10 is required to bear significant weight andlor its contents are relatively heavy.

Figures 6 to 12 provide orthogonal views of the container 10. Preferably, as observed In Figure 10, the hinge 140 Is provided with flexible hand-grppable handles 900 coupled to the hinge 140 m regions near extremities of the hinge 140 whereat it meets the side panels 70a, 70b, 80a, 80b.

In smaller versions of the container 10, a single central hand-gnppable handle is provided. More than two such grippable handles can be provided if required.

An upper edge of the front and rear panels 60, 50 can be provided with reinforcement, for example plastics material rods Incorporated therein, in order to strengthen the container 10 further to Improve its nudity when m an expanded configuration. - 12

À 4 4 À . . À e ÀÀ À À 4 À . ... À Moreover, it will be further appreciated that modifications can be made to embodiments of the Invention described in the foregoing without departing from the scope of the invention.

As will be elucidated in the following, the container 10 of the invention described m the foregoing is susceptible to being adapted for use In a wide range of applications.

In a first application of use, the container Is deployed as a rubbish bag, for example to provide a spatial equivalent of a conventional dustbin or wheelybin; in such use, the container 10 Is preferably of generally elongate form with an access Ed at a first end of the elongate fonn and a plurality of wheels at a second end of the elongate form remote from the first end. When the I container 10 Is employed as a rubbish bag, it Is preferably provided with one or more drainage features, for example holes, m lower regions thereof. Moreover, where such a rubbish bag is to be deployed in out-door conditions, it is preferably fabricated from materials which are not rapidly degraded by being exposed to rain, damp and cold; In this respects, plastics materials such as nylon, polypropylene, polyvinyl chloride (PVC), acetate, natural and/or synthetic rubberized materials, as well as corrosion-resstant wire mesh, aluminium sheet are especially preferred for the container 10. Beneficially, the container 10 when adapted to function as a dustbin or wheelybn Is of benefit in that it occupies less space, is easier to transport and deploy, is potentially easier to manufacture, and Is of lower weight m comparison to conventional dustbins and wheelybms.

In a second application of use, the container 10 described in the foregoing is deployed as a general storage box, namely for indoor and/or outdoor situations. For example, m this apphcaton, the container 10 is susceptible to being manufactured as a high-quality up-market product for indoor use wherein its panels are stiffened by including, for example, plywood or medium density fibreboard (MDF) therein, the panels including foam padding, for example elastic polyurethane foam padding, and an outer covering of cloth or desirably natural leather or Imitation leather; the foam padding assists to prevent panels from being dented and/or fractured.

Alternatively, woven nylon cloth, for example black woven nylon cloth, can be used to cover the panels of the container 10 to provide a durable hard-wearing presentable finish thereto.

In a third application of use, the container 10 Is deployed as a chld's toy box, for example in a nursery andlor a chld's bedroom, the container 10 provdmg an advantage in that it can be neatly - 13 À À . . À . . . . . collapsed and tidied away m a domestic environment when its contents have been disgorged onto a floor area and/or table area. Similarly, the container 10 can be employed in a domestic environment and/or accommodation environment as a linen box for storing cloth items such as one or more of bed hnen, towels, curtains, clothes, coats, shoes, tablecloths and such like. In this respect, the container 10 is preferably fabricated from a material which allows moisture to diffuse into andlor from an interior volume of the container 10 so that the container 10 Is able to "breathe" to try to reduce a tendency for its contents to become musty and/or moldy after prolonged storage within the container 10.

In a further application of use, the container 10 is adapted for garden and/or horticultural use wherem it Is susceptible to storing garden leaves, choppings and any other sort of garden waste. I More preferably, the container 10 Is constructed from materials which render it susceptible to: being used as a collapsible compost heap such that, after composting, contents of the container 10 can be spread onto flower, lawns and vegetable beds, and then the container 10 then stored compactly In a garage or shed rendering land area where the container 10 stood when deployed as a compost heap available for garden use.

In a further apphcaton of use, the container 10 is susceptible to being deployed as a file box suitable for use in clerical and/or office environments where paper files need to be stored for a period of time before being destroyed if no longer relevant.
