DESCRIPTION OF PREFERRED EMBODIMENTS
A modular container 10 according to the invention is depicted in Figure 5. The container is formed from a foldable unitary blank 12, preferably formed of corrugated polymeric sheet material, cardboard or the like. The container is intended for the convenient storage or display of articles, such as files, papers, boxes, drawers and articles of a similar nature. The container may be easily erected to form a single container, or may simply be adapted to be joined to other like containers. The containers joined in this manner may be conveniently separated again to form single containers, or may be collapsed back into flattened blanks for storage.
Figure 1 shows the blank 12 which has a base panel 14, and opposed first and second side panels 16 and 18 extending from the sides of the base panel. When folded into a vertical orientation, the first and second side panels form the side walls of the container. On the side panels are provided respective first and second end connecting panels 20 and 22 which are foldable from the first and second side panels respectively. The first end connecting panels have projecting connecting tabs 24, which are engageable with corresponding connecting apertures 26 formed in the second end connecting panels. When the projecting tabs of the first end connecting panels are engaged in the apertures of the second end connecting panels, the first stage in the assembly of the end panels 27 of the container 10 is completed.
In the preferred embodiment, a number of end panel portions are provided, from which the end panels 27 are formed. A third end panel portion 28 extends from each end of the base panel 14. A first end panel portion 30 is provided on the upper edge of each of the third end panel portions, and second end panel portions 32 extend from either side of the first end panel portions. Four slots 34 are provided on the first end panel portion, and two cutaways 36 are provided on each of the second end panel portions which may be folded out from the cutaway to form tongues 38.
When the first and second end panel portions 30, 32 are placed in overlapping relationship with one another, the tongues 38 are locatable through the slots 34 and project through to the other side, presently being arranged outwardly of the container that is being assembled. This overlapping relationship is accomplished by folding each of the second end panel portions in the direction shown in Figure 6, towards the first end panel portion. The second stage in the assembly of the end panel 27 of the container 10 is then completed.
The combination of overlapping first and second end panel portions 30, 32 is then folded inwardly, enveloping the connected first and second end connecting panels 20, 22. Projections 39, extending from the first end panel portion, are located in complemental grooves 41 provided on the base panel 14. The third and final stage in the assembly of the end panel 27 of the container 10 is then completed. In this manner the third end panel portion 28 is located externally of the container and the combination of overlapping first and second end panel portions is located inwardly, with the tongues 38 projecting into the container. This forms a particularly rigid end panel.
In further embodiments of the invention, the end panels may be formed in various different ways. In a second embodiment, as shown in Figure 7, only one second end panel portion 32 extends from one of the sides of the first end panel portion 30. Four slots 34 are provided on the first end panel portion and four tongues 38 are provided on the second end panel portion. The overlapping relationship is accomplished by folding the second end panel portion in the direction shown in Figure 7, towards the first end panel portion.
In a third embodiment, as shown in Figure 8, the first end panel portion 30 extends from the upper edge of the second end panel portion 32, which is provided on the
base panel 14. Four slots 34 are provided on the first end panel portion and four tongues 38 are provided on the second end panel portion. The overlapping relationship is accomplished by folding the first end panel portion in the direction shown in Figure 8, towards the second end panel portion. It will be appreciated that the first end panel portion could be provided on the base panel, with the second end panel portion extending from the upper edge thereof and foldable outwardly to overlap the first end panel portion. It will also be appreciated that alternative means of connecting the side panels 16,18 to the end panels are required in this embodiment.
In a fourth embodiment, as shown in Figure 9, no end connecting panels are utilised, with the second end panel portions 32 instead extending from each of the first and second side panels 16 and 18. Four slots 34 are provided on the first end panel portion 30 and two tongues 38 are provided on each of the second end panel portions. The overlapping relationship is accomplished by folding each of the second end panel portions in the direction shown in Figure 9, towards the first end panel portion, thereby simultaneously connecting the side panels to the end panel so formed.
It will be understood that the container 10 may further include the subject matter as disclosed in international patent application number PCT/I B01/00201 (WO 01/60702) in order to connect like containers 10 in side by side relationship. In Figures 1 and 6, it can be seen that the container, accordingly, is also provided with an end container connecting tab 40, formed from a cutaway on the first end connecting panel 20. The end container connecting tab may be folded externally from the cutaway to project from the first side panel 16. A container-locating aperture 42 is provided on the second end panel 27 connecting portion 22. Prior to the assembly of an end panel of the container, the end container connecting tab of a first container is positioned into the container- locating aperture of a second like container. When the end container connecting tab is engaged in the container-locating aperture, the end panel may be folded into the assembled position, thereby enveloping the container connecting arrangement. If a further container had been required, the end container connecting tab of the second container would have been folded out from the corresponding cutaway to project away from the second container prior to the end panel being placed in position.
It will be appreciated that a number of like containers 10 may be connected together in a rigid arrangement, with files, papers or boxes and the like being conveniently stored in
the containers. In addition, in the preferred embodiment, the containers are provided with locating projections 44 and locating recesses 46, thereby enabling containers to be positioned securely on top of one another in a stacked configuration, with the locating projections of the lower container being conveniently positioned in the locating recesses of the upper container. In this manner, modular shelving is provided.
Alternatively, the containers 10 (connected or otherwise) may be arranged on their ends, and drawers 48, preferably also being formed from unitary blanks, may be placed within the containers, resting on the tongues 38 that project within the container, as shown in Figure 10.
The blank 12 may conveniently be folded in a manner that provides a particularly flat configuration, suitable for transportation. Figures 2 and 3 indicate the manner in which this is achieved, with the tongues 38 obviously being retained within the cutaways 36.
