COMPLETE SPECIFICATION STANDARD PATENT Application Number: Lodged: 9 Invention Title: COLLAPSIBLE STACKABLE CONTAINER The following statement is a full description of this invention, including the best method of performing it known to us COLLAPSIBLE STACKABLE CONTAINER This invention relates to a container for transporting articles such as produce or components for use in manufacture or the like.

Generally it is preferred that produce and components are transported in suitably sized containers which are collapsible so that after the produce or components have been transported to a desired location the containers can be collapsed and returned to a manufacturer or producer for re-use. The collapsibility of the containers ensures that when the containers are returned minimum space is occupied therefore ensuring that the pay load to be carried by a truck or other vehicle is as large as possible. Furthermore, the collapsibility of the container also facilitates storage thereof when not in use.

The problem of creating a workable collapsible container has been addressed in prior art patent references. Some of these earlier patents have attempted to address the problems of maintaining stackability of the container in 15 both the collapsed form and the erected form.

In one reference, United States Patent No. 4186841, there is described a stackable, collapsible container having four corner posts with an upper portion of each post including a protrusion and a lower portion of each post including an aperture. The containers may be stacked on top of each other in the erected configuration such that the protrusions on the upper portion of the posts of one container co-operate with the corresponding apertures of the container *o immediately thereabove.

This reference also describes the provision of additional protrusions at a ooo°median section of each post such that, when the container is collapsed, the protrusions in the median section are exposed to enable co-operation of the additional protrusions with corresponding apertures in another container in the collapsed configuration stacked immediately thereabove.

The device described in this reference has the difficulty that, as a result of the manner of collapsing of the container, the height of the side walls of the container is limited to being less than the length of the end walls thereof, and the height of the end walls is limited to being less than the length of the side walls thereof. If the end and/or side walls are of greater length than this, folding would not be possible as the walls would impact against each other in the folding process. This device also requires that the protrusion at the median section of the post is the same as that at the upper portion thereof. The containers also, whether in the erect or collapsed configuration, require quite accurate placement of the containers in relation to each other to ensure that the protrusion is properly positioned within the aperture.

United States Patent No. 3981410 describes a similar device in which protrusions are positioned at the lower portion of the corner posts, with apertures provided in the median and upper portions of the corner posts. A further disadvantage of this type of construction is highlighted in this patent, in that this type of construction requires two of the walls to be of a different strength to the other two walls, as two of the walls are supported by the main support posts, whereas the other two are not. This causes an inherent degree of weakness in S* 15 the unsupported wall.

Another reference, International Patent Publication No. WO95/09110 discloses a container which is collapsible, however, it does not specifically address the issue of the ability to stack the container in the collapsed and erected configurations. Once again, the device described in this reference has the same limitation described above regarding the height of the container walls in the erected configuration being limited by the lengthwise dimensions of the container.

It is also an ongoing problem with stackable containers that difficulties can be encountered when stacking the containers in that in many prior art devices the containers must be positioned accurately in relation to each other to ensure that the mating components connect correctly. This is particularly the case where the container is in the erected condition as significant height can be attained on stacking of a small number of containers, and a greater height often results in more difficulty in positioning the containers with respect to one another.

It is an object of the present invention to provide a collapsible stackable container which overcomes or ameliorates at least one or more of the problems existing with prior art devices of this type, or provides a new and useful alternative to existing devices.

According to a first aspect, the present invention provides a container for transporting articles when in an erect condition and being collapsible to a collapsed state when not required for transporting articles, said container including a base including a floor structure; a plurality of wall components hingedly coupled to said base for defining a rectangular storage compartment when in said erect condition with two of said wall components forming side walls of the storage compartment and two of said wall components forming end walls of the storage compartment, said wall components being collapsible from said erect condition to said collapsed state wherein said wall components do not extend substantially beyond a perimeter of said base; S* 15 each of said wall components having substantially rigid edge members being arranged adjacent one another at or adjacent corners of the floor structure of said base in the erect condition of the container, and first and second coupling means being provided so that the coupling means can be connected together to secure the wall components together; and at least one of said wall components being formed in two portions which are hingedly coupled to one another such that the portions can be folded at hinge S. means between the portions and simultaneously collapsed to reduce the container to said collapsed state.

In accordance with a second aspect of the present invention, there is provided a container for transporting articles including a base having a rectangular floor structure and a post member at each corner of the rectangular floor structure; a plurality of wall components coupled to the base for defining a rectangular storage compartment when in an erect condition, with said wall components being disposed generally upright relative to said floor structure, said wall components being collapsible from said erect condition to a collapsed state without decoupling said wall components from said base where said wall components are supported on said floor structure being disposed generally parallel to said floor structure; at least one of said wall components being formed in two panel sections hingedly coupled by hinge means to one another such that the panel sections can be folded at said hinge means when being disposed in said collapsed state; and each of said post members being configured whereby in a stack of said containers disposed in the collapsed state, a lower end of each said post member of a first said container engages with and is supported by an upper end of a said post member of the container located immediately below the first said container.

In accordance with a still further aspect of the present invention, there is provided a container for transporting articles including a base having a rectangular floor structure and a post member fixed to said S 15 floor structure located at each corner of the rectangular floor structure; a side wall component coupled to the base extending along each side of the rectangular floor structure, each said side wall component being formed in two panel sections hingedly coupled by first hinge means to one another with a lowermost one of said panel sections being hingedly coupled to said base by second hinge means whereby the panel sections can be folded at said first hinge means when being disposed into a collapsed state with said panel sections being disposed generally parallel with said floor structure; an end wall component coupled to the base extending along each end of the rectangular floor structure, the end wall components being hingedly connected via third hinge means to said base whereby in the collapsed state, said end wall components are disposed generally parallel to said floor structure; first and second coupling means being provided operable between adjacent edge zones of the side wall components and the end wall components when disposed in an erect condition upright relative to said floor structure, said first and second coupling means being activatable to retain said adjacent edge zones of the side wall and the end wall components together, but be releasable therefrom when the container is to be returned to said collapsed state; and each of said post members being configured whereby in a stack of said containers disposed in the collapsed state, a lower end of each said post member of a first said container engages with and is supported by an upper end of a said post member of the container located immediately below the first said container.

Preferred features of this invention may be as defined in claims 4 to 24 inclusive as annexed hereto which are hereby made part of this disclosure by this reference thereto.

A preferred embodiment of the invention will now be described, by way of example, with reference to the accompanying drawings in which: Figure 1 is a perspective view of a container in accordance with an embodiment of the invention in the erected configuration; o: Figure 2 is an end view of the container of Figure 1; S 15 Figure 3 is an enlarged end elevational view of the foot portion of the embodiment of Figure 1; Figure 4 is a perspective view of the foot of Figure 3; Figure 5 is an enlarged view of the portion of the container indicated in °ooo• Figure 2 relating to the connection between respective wall components of that embodiment; Figure 6 is an enlarged view of the portion of the container indicated in Figure 2 relating to the connection between the wall components and the base posts of the container of that embodiment; Figure 7 is an end elevational view of a container in accordance with the embodiment of Figure 1 in the collapsed configuration; Figure 8 is a side elevational view of two containers of the type shown in Figure 1 in the collapsed configuration and stacked one above the other; and Figure 9 is a side elevational view of two containers of the type shown in Figure 1 in the erected configuration and stacked one above the other.

With reference to Figure 1 a container 10 is shown which has side wall components 12 and 14 and end wall components 16 and 18. The end wall component 18 forms a door which can be opened and closed in the direction of double headed arrow A to gain access to the container The wall components 12 to 18 are coupled to a base 20 so that the wall components can be folded down into a collapsed condition as will be described in more detail hereinafter. Each of the wall components 12, 14, 16 and 18 is a bifold wall component formed from two portions, for example for the side wall 12, this wall is comprised of portions 12a and 12b shown in Figure 1 which are hinged together so that the portions 12a and 12b can fold in relation to each other as will also be described in more detail hereinafter. The side wall component 14 is similar to the wall component 12 and also formed in two parts.

End wall components 16 and 18 are also formed in two parts although in other embodiments, may be formed as one part. See, for example, parts 18a and 18b as shown in Figure 1.

The container 10 has a foot 30 at each corner for enabling stacking of the S 15 containers in both the erected article transport condition shown in Figure 1 and in a collapsed condition as described in more detail hereinafter. The base includes a rectangular frame formed by opposed side bars 20a and opposed end bars 20d. Connected between the opposed side bars 20a are channels 32 for .oo.•i receiving the tynes of a forklift truck to enable the container to be lifted from either side 12 or 14. The base 20 also includes channels 34 between opposed base end frame members 20d for receiving the tynes of a forklift truck to enable the container 10 to be lifted from the ends 16 or 18. The channels 32 and 34 include bottom plate strips 36, which are provided to help prevent tipping of the container when in use. A panel (not shown) may be provided as the internal floor for the container.

The wall components 12, 14, 16 and 18 have end wall component posts 13, 15, 17, 19, 21, 23, 25 and 27. Intermediate posts (not shown) may also be provided in the wall components 12, 14, 16 and 18 and the wall components may be completed by suitable panels, mesh or the like in a known way.

As is shown in Figure 1, adjacent wall component posts of adjacent wall components, such as the wall component post pairs 15 and 17, 19 and 21, 23 and 25, and 27 and 13 are arranged adjacent one another but do not overlap so that a small space is formed therebetween. The space between the wall component post pairs accommodates cooperating connection members (which will be described in more detail hereinafter) for coupling the wall components together.

As shown in Figure 2, the wall component 18 includes the wall component panels 18a and 18b which are coupled together by hinges 35 so that the panels 18a and 18b can be folded with respect to each other. The wall component 18 also functions as a door. Apart from the components which enable the wall component 18 to function as a door, as will be apparent from the description as follows, the wall component 16 is similar to the wall component 18. The wall component 18 has an upper wall component frame 41 and a lower wall component frame 43 formed around the panels 18a and 18b respectively.

The upper and lower portions of posts 19 and 17 are hinged together by 15 hinges 49 and 51 respectively. The hinges 35 are co-axial with the hinges 49 and V 51 so that when the panels 18a and 18b located within the upper and lower frame members 41 and 43 the wall component 18 are coplanar with the posts 17 and 19, the frame members 41, 43 together with the upper parts of posts 19 and •17 can fold in the direction of arrow C in Figure 1 to bring the upper frame portion 41 into overlapping and adjacent relationship with respect to the lower frame member 43.

2In order for the wall component 18 to function as a door the panels 18a and 18b are not fixed to posts 17 and 19 as in the case of the end panel 16 (being attached to posts 25 and 27) but rather the panels 18a and 18b are fixed to the frame members 41 and 43, which are hinged to the post 17 by hinges 61 and 63 shown in Figure 2. The frame members 41 and 43 have latches 62 and 64 which can engage with sleeves (not shown) on the post 19. The panels 18a and 18b therefore form a door 59. In the erect condition, in order to open the door 59, the latches 62 and 64 are simply released and the panels 18a and 18b swing about hinges 61 and 63 as a single unit to enable the door to open. With this arrangement the panels 18a and 18b form the door 59 of the wall component 18 with the posts 17, 19 and upper joining frame member 47 and lower frame member 48 acting as the door frame.

As mentioned above, and shown in Figure 1, the side wall components 12 and 14 are formed from the two panels, being 12a and 12b in the case of the side wall component 12, and 14a and 14b in the case of the side wall component 14. Panels 12a and 12b are hinged together, and panels 14a and 14b and are hinged together, by hinges 75 so that the top part can fold downwardly relative to the lower part as shown by arrow D on side wall component 12 (Figure 1).

In order to hold the side wall components 12 and 14 in fixed relation to the end wall components 16 and 18 when the container is in the erected condition shown in Figure 1, connector components 40 are provided for each of the upper and lower portions of each of the side and end wall components 12, 14, 16, and 18. The connector components 40 are shown in greater detail in Figure 5. The i connection between the posts 19 and 21 will now be discussed in an exemplary 15 manner, with similar constructions being assumed for the other connector components.

As shown in Figure 5, the post 19 has a protruding bar component 70, in the form of a plate which has a first section 72 welded to the post 19 and a second section 73 which is bent outwardly of the post 19, and then extends some distance along the length of the post parallel thereto.

The wall component post 21 carries a securing sleeve component 80 of the connecting member 40. The securing sleeve component 80 comprises a pair of plates 81 and 83 with a bar 85 extending therebetween. A square sleeve 87 is arranged on the bar 85 for sliding movement up and down along the bar 85. The sleeve 87 is considerably bigger than the bar 85 and, when the wall components are in the erected condition shown in Figures 1 and 2, the sleeve 87 can be moved into a position whereby the sleeve 87 slides down over the portion 73 of the plate 70 to thereby couple the component 80 to the component 70 to in turn couple the adjacent wall component 19 and 21 together. Thus, the adjacent wall components can be locked together by moving the sleeve 87 downwardly so that it engages the plate 70 or released by moving the sleeve 87 upwardly so as it releases from the plate Figures 3 and 4 show in more detail the foot 30 of each corner of the container 10. The foot 30 at the intersection of the base frame members and 20d will be described in an exemplary manner. Extending upwardly from the base 20 at the corner is a base post 90 which is formed from square section hollow tube. The foot 30 includes a square tube section 91 which extends diagonally across the corner of the container 10 and which is cut flush with the frame members 20a, Lower surface 93 of the tube section 91 forms a generally horizontal abutment surface the function of which will be described hereinafter. The tube section 91 has an outwardly directed surface 95 and an inwardly directed surface 97. Welded to the surface 95 is a downwardly projecting pin 99 and welded to the surface 97 extending downwardly from the surface at an angle to the vertical S 15 is a generally downwardly inclined angled plate 98. The angled plate 98 is inclined with respect to the vertical by approximately 37 degrees, though the actual angle may be varied somewhat. Angles of up to 60 degrees and even higher are considered particularly useful.

The components in Figure 6 will now be considered. The wall components 12, 14, 16, and 18, as described above are hinged at the base edge thereof to the base of the container. To assist in maintaining the wall components in the S erected position, fixing means 102 are provided on the wall component posts for connection with the respective base posts 90. The fixing means 102 comprises a lOS latch 103 provided on the relevant wall component post (in this case wall o*°oOS component post 13 associated with wall component 14), which latch 103 is receivable in an aperture in the top of base post 90 as shown in Figure 6. To release the wall component 14 from the base post 90 the latch 103 is simply lifted so that it releases from the base post The end wall components 16 and 18 are hinged directly to the frame members 20d and 20b respectively of the base 20 by hinges 121. As is shown in Figure 1, a first short wall section 107 extends between the base frame member and the side wall component 12. A second short wall section 108 extends between base frame member 20c and side wall component 14. As can be seen in Figure 2, the second short wall section 108 is slightly taller than the first short wall section 107 for reasons which will be explained. The wall component 12 is hingedly connected to the top of the short wall section 107 by hinges 105. The wall component 14 is also arranged on top of short wall section 108 and pivoted between the adjacent post 90 in the same manner as the wall component 12 by a hinge 109.

In order to collapse the container the cooperating connection members are released from one another and each of the wall components 12 to 18 are first folded in half by lowering the top part of the wall components 12 to 18 down adjacent to the bottom parts of those wall components. The latches 103 are removed from the base post 90. The end wall components 16 and 18 are then folded about the hinges 121 down flat onto the base 20. The two end wall 15 components 16 and 18 in the folded down position do not overlap one another and are merely arranged adjacent one another on the base The wall component 12 is then folded about hinge 105 onto the two end wall components 16 and 18. It should be noted that the height of the wall 105, as is best shown in Figure 7, is just level with the height of the upper surface of the S 20 collapsed wall components 16 and 18 so that when the wall component 12 is folded downwardly into position shown in Figure 13 it sits neatly and squarely on *top of the folded wall components 16 and 18.

The wall component 14 is then folded down about hinge 109 on top of the oowall component 12. In this regard it should also be noted that the height of the o wall 108 is approximately equal to the height of the upper surface of the wall component 12 when it is in its folded condition so that the wall component 14 can be folded down neatly and squarely on top of the wall component 12.

In order to stack the folded and collapsed wall component as shown in Figure 7, one container 10 is located above another container 10' as is shown in Figure 8. The pins 99 associated with the container 10 shown in Figure 8 are inserted into the base posts 90' of the lowermost container 10' and the container rests on top of the base posts 90' by virtue of the abutment of the abutment surface 93 of each foot 30 on top of a respective post 90'. The location of the pins 99 in the post 90' prevent substantial movement of the upper container relative to the lower container 10' and the engagement and abutment of the abutment surface 93 on top of the base post 90' ensures secure and firm location of the container 10 above the container Figure 9 shows an end view of erected containers as per that shown in Figure 2, but in a stacked condition for transport on a truck or the like. The upper container 10 is located on the lower container 10' so that the abutment surface 93 of each foot 30 of the top container 10 rests down on top of the adjacent side wall component posts at each corner of the lower container 10'. An abutment surface 93 will rest upon each of the wall component post pairs 15' and 17', 19' and 21', 23' and 25', and 27' and 13' at the relevant corners of the containers '.*and 10'. The inclined plate 98 acts to centre the foot 30 with respect to each of the post pairs by the top of those posts engaging the inclined plate 98 when the containers are being stacked, and guiding the upper container 10 into the proper position directly above the lower container 10' as the container 10 moves downwardly onto the container In a further embodiment, the container 10 may include a lid or cover which is preferably formed from fabric such as canvas, polyethylene or the like. The cover may be secured to one of the wall components, such as wall component 14 by any suitable attachment and may include straps which may be used to tie down the cover to close the container 10. If desired, plastic ties (not shown) can be used in conjunction with the straps and which must be cut before the straps can be removed to show that the lid has been removed or opened. This can be used to indicate tampering with the contents of the container 10 if the ties are cut prior to receipt of the container at the required destination. Similarly, plastic ties and the like can also be used in conjunction with the door on the wall component 18 which must be cut in order to open the door 18 to provide an indication on whether the door 18 has been previously opened which may suggest tampering with the contents of the container I I 12 Since modifications within the spirit and scope of the invention may readily be effected by persons skilled within the art, it is to be understood that this invention is not limited to the particular embodiments described by way of example hereinabove.
