Collapsible household containers having a foldable wall section with shape-retaining characteristics are disclosed. In particular, collapsible laundry baskets, buckets, colanders, dish drainers, and cups are provided. The folding region may include foldable tiers of a flexible material, each tier having at least one stable, relatively expanded position and at least one stable, relatively collapsed position; and an intervening, non-folding tier composed of a different, relatively rigid material.

A collapsible generally triangular pizza storage container with a set of microwaveable triangular trays for the separation, microwaving and serving of individual slices of pizza. The storage container expands to approximately two times its collapsed configuration. It uses a novel, non-accordion type pleating of its side walls that allow for the container to have the same horizontal cross sectional size along the vertical axis of the container. The pleat design has three wall sections that each fold in on themselves to form a set of three nested side wall portions. Each wall section is separated from the other by a small gap. The lid also has a generally triangular configuration with a compressible gasket, a set of locking wings extending from the periphery that frictionally engage a rigid triangular top ring of the container, and a central air vent.

A foldable and collapsible storage container with a bottom wall, and two pairs of parallel side walls. The bottom wall, first pair of side walls and second pair of side walls define a storage volume. A foldable storage volume partition may include a partition wall that extends between the third side wall and the fourth side wall and supports the third side wall and the fourth side wall in an upright position. The foldable storage partition may include a partition bottom hingedly connected to the partition wall that faces the bottom wall. The third and fourth side walls each may include fold locations that divide the third and fourth side walls into a first part and a second part. The partition may engage the third and fourth side walls to inhibit folding of the third and fourth side walls.

Collapsible household containers having a foldable wall section with shape-retaining characteristics are disclosed. In particular, collapsible laundry baskets, buckets, colanders, dish drainers, cups, and bottles are provided. The folding region may include foldable tiers of a flexible material, each tier having at least one stable, relatively expanded position and at least one stable, relatively collapsed position; and an intervening, non-folding tier composed of a different, relatively rigid material.

A collapsible container according to one embodiment of the present invention includes a base and a plurality of walls, including a first wall, collapsible onto the base. A support is movable between a first position and a second position relative to the first wall, such that an identical container would stack on the collapsible container at a first height when the support is in the first position and at a second height when the support is in the second position. In another embodiment, different stacking heights can be achieved by rotating the upper container 180 degrees relative to the lower container.

A collapsible container (100) has an unfolded configuration for use of the container and a folded configuration for storage of the container. The container 100 comprises a plurality of panels arranged to form a base (104a); a first side wall (104h) pivotally connected to a first edge of the base (104a) by a first flexible hinge member (108); a second side wall (104b) pivotally connected to a second edge of the base (104a) by a second flexible hinge member (108), the second edge of the base being adjacent to the first edge of the base. In the folded configuration, the first side wall (104h) lies between the base (104a) and the second side wall (104b) and the second flexible hinge member (108) is longer than the first flexible hinge member (108) so as to accommodate the first side wall (104h) between the base (104a) and the second side wall (104b).

A foldable power strip storage tray is provided. The foldable power strip storage tray includes: a main body provided with an inner space to accommodate a power strip; a fixing portion having one side opened and having an upper end hanging on one side of a desk, and configured to support a load of the main body and simultaneously to fix the main body to a lower side of the desk when a lower end of the fixing portion is received in the main body; and a holding portion disposed on an upper side of the desk, and configured to prevent the fixing portion from sliding from one side of the desk or from being released by a movement when an area of a predetermined length of an upper end of the fixing portion is drawn in the holding portion. Accordingly, since the power strip is accommodated in the inner space of the power strip storage tray attached to the lower side of the desk, problems that the power strip or electric cables are stepped on by a foot and thus are damaged, power supply to electric devices is suddenly stopped, or a moving line of a cleaner is hindered when the floor is cleaned can be solved. In addition, when the power strip is not accommodated in the inner space of the power strip storage tray, the tray is unfolded and then is folded, and is stored with its volume being minimized, and thus there is a space saving effect. In addition, the charging cable connected with the terminal can be prevented from being released by a movement, and there is an effect of holding the terminal on the upper side of the desk.

A tank, including: a foldable liquid container; and a frame, for housing the foldable liquid container, thereby avoiding collapse of the foldable liquid container.

Collapsible reusable watertight carrying cases are provided in sizes varying from small containers without wheels to large sealable container bins on wheels, to provide large quantities of water or other supplies and cargo. The cases are assembled or disassembled from a joined flat space-saving configuration to a functioning case and vice-versa. The sides of the cases are erected progressively by hand by interlocking self sealing reciprocating channel and channel engaging members elements at the corners. The panels also disassemble progressively by being manually pulled apart. Optional foldable locking latches provide stability and aesthetics to the carrying case. When folded into a flat storage or shipping configuration, the panels stay together, resisting unfolding by virtue of snaps which are either molded into the panels or bonded to them. The carrying cases are resistant to water, dirt, bacteria, molds, allergens, and inclement weather.
