DESCRIPTION:
BRIEF SUMMARY
This invention relates to containers of the type which includes as essential parts, a base, four sides which are demountably securable to the base so as to stand upright and coupling means to allow coupling of the sides together thereby to form a four sided enclosure. Preferably such containers also include a lid securable to the sides. Containers of the above type are presently known where the base is a pallet.
The above form of container when using a pallet as a base is frequently provided with a floor panel which acts as a support surface over the pallet battens for a liner bag of plastics material located within the enclosure. The liner bag can be used to house dry and wet goods and liquids. With containers as just described the connections of the sides to the pallet base have sometimes allowed movement between the sides and the base and the floor panel to the extent that the liner bag has been damaged. Where the container has been used for the transport of liquid leakage has sometimes occurred.
This invention advances the art of containers of the above type by overcoming at least the movement between component problem as outlined above thereby providing for better containers for the transport of liquid.
Broadly, the invention can be said to comprise a collapsible container including a base with four upstanding interlockable demountable wall panels which are hooked to the base by hook means requiring vertical and then horizontal movement of each wall panel to connect it to the base, lateral support members on the edges of the base relieve the hook means from outwardly directed loads applied by goods within the enclosure formed by the four wall panels.
More specifically, the invention can be said to comprise a collapsible container having a base of rectangular form providing a support surface, retaining means which upstand from the support surface and which extend along and lie adjacent each side of the base and terminate short of each corner of the base, apertures in said base inwardly of said retaining means and adjacent to the retaining means, two pairs of rectangular wall panels each panel having a top edge and a bottom edge and two side edges with the height of all panels between the top edge and the bottom edge being substantially the same and the side edge to side edge width of the panels of one pair being greater than the width of the panels of the other pair, a plurality of attachment means on bottom edge of each wall panel, the attachment means of each panel includes hooks each having a body part which extends away from the bottom edge of the panel and an elongated lateral lug where the lugs of a panel point in the same direction and are substantially parallel to the bottom edge of the panel and are in a common plane substantially parallel to the plane of the panel, the spacing of the attachment means of each panel corresponds with the spacing of the apertures of a side of the base and size of the apertures permits the attachment means to pass therethrough so the lugs thereof can hook under the base adjacent the apertures as a result of lateral movement of the panel relative to the base, releasable interconnecting means on the side edges of each panel so that when an enclosure is formed on the base by mounting the four panels thereon with the panels of each pair in opposed relationship and the side edges of the wider panels overlying the side edges of the narrower panels engagement of the interconnecting means locks the panels together to form an enclosure on the base with the adjacent side edges of the narrower and wider panels in parallel aligned relationship.
Preferred embodiments of the present invention will now be described with reference to the accompanying drawings in which:
FIG. 1 is a plan view of a base member for a container according to the invention,
FIG. 2 is an elevation of one of the side panels (which form a pair) used for the container of FIG. 1,
FIG. 3 is an elevation of the other of the side panels (used as a pair) for the container of FIG. 1,
FIG. 4 is the first step in a
