Definitions
- This invention relates to collapsible containers and, more particularly, to containers that form structures of uniform height when in the collapsed condition to allow stacking of the containers.
- Containers that are collapsible typically have side walls constructed in such a manner so as to enable them to be folded into the collapsed condition in a specific sequence to achieve the minimum collapsed height possible.
- the dimensions and configuration of the container permit the collapsing thereof into a relatively flat structure, which may be achieved by the walls of the container having differing heights, by the base of the container being so large that no overlapping of the collapsed walls occurs, or by an asymmetrical design of the walls of the container. Side walls of uneven height lead to the container not being stackable in a stable manner, whilst large container bases or asymmetrical designs may be impractical.
- a collapsible container including:- a base portion having first and second opposed sets of base walls extending therefrom; first and second sets of hinge axes defined in said first and second sets of base walls, wherein the first set of hinge axes is located in a plane below that in which the second set of hinge axes is located; and first and second sets of opposed side walls configured to engage the first and second sets of hinge axes to define the container, the side walls being pivotally displaceable between an upright and a collapsed condition, wherein the dimensions of the side walls are selected so that in the collapsed condition, opposed sets of side walls do not overlap and wherein the container is stackable in a collapsed as well as in an operative condition.
- the first and second sets of opposed side walls may be provided with engaging formations that interlock in the operative condition so as to retain the side walls in a fixed relationship relative to each other.
- free edge regions of the side walls of the container may be in a common plane.
- the height of each wall of the second set of side walls is about equal to half of the width of a wall of the first set of side walls.
- the container In the collapsed condition, the container may form a unit having a uniform height so permit stacking of the container.
- the base portion may be square or rectangular in plan view.
- the first set of base walls may be lower than the second set of base walls so that the first set of hinge axes is located in a plane below that in which the second set of hinge axes is located.
- the hinge axes may be defined by two or more recesses configured and dimensioned to receive complementary engaging formations of the side walls so that pivoting of the side walls about said hinge axes is permitted.
- the recesses may be configured so as to inhibit pivoting of the side walls past the upright position in a direction away from the base portion but to permit pivoting of the side walls inwardly, towards the base portion into the collapsed condition.
- the base portion and walls may be provided with a plurality of openings to permit air to flow into the container.
- One set of opposed side walls may be provided with flanges along their lateral edges extending substantially perpendicularly therefrom towards the opposed side wall.
- Each flange may include openings therein for receiving engaging formations provided on the other set of opposed side walls therethrough.
- the engaging formations may be in the form of one or more clips having opposed gripping formations that are biased into an engaging condition.
- the side walls In order to collapse the container from the operative into the collapsed condition, the side walls may be disengaged and the first opposed set of side walls may then be pivoted towards the base portion.
- the second opposed set of side walls may be pivoted towards the base portion so that they overlay the first opposed set of side walls.
- the order of folding the side walls into the collapsed condition is thus uncomplicated.
- the resulting collapsed container presents a relatively flat unit to allow for space conserving stacking and storage of the container.
- the side walls may be parallel to the base portion.
- a container in the collapsed condition may serve as a lid for a container in the operative condition.
- the height of the collapsed container may be substantially equal to the height of the second set of opposed base walls.
- One or both sets of opposed side walls may be provided with handle portions in the form of suitably dimensioned openings or handles.
- the container may be manufactured by an injection molding process using any suitable synthetic plastics material such as, for example, polypropylene. Other suitable manufacturing processes and/or materials may alternatively be used.
- a plurality of containers When in the operative condition, a plurality of containers may be stacked during transport or storage thereof.
- a first layer of containers is formed by positioning three containers adjacent each other so that their second set of side walls touch and by positioning a further two containers with their first set of side walls touching and their second set of side walls touching first set of side walls of the other three containers.
- a second layer of containers having the same arrangement of containers as the first layer may be stacked onto the first layer.
- the arrangement of the containers in the second layer may be rotated by 180 degrees relative to the arrangement of containers in the first layer. Therefore, the containers of the first and second layers are not stacked in register on top of each other, thus permitting a large number of layers to be stacked.
- free edges of the side walls and free edges of the base portion may be provided with complementary engaging formations which engage each other when the containers are in the stacked condition.
- the dimensions of the container may vary according to a user's particular requirements. Typically, the container is about 400 mm wide, 600 mm long and between 100 and 240 mm deep in the operative condition.
