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 in 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. 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.

A collapsible container for receiving delivery packages is disclosed herein. The collapsible container comprises a bottom, and collapsible front and rear walls. Further, the collapsible container comprises sidewalls mounted to the front wall and the rear wall. Each of the sidewalls comprises a rail. Additionally, the collapsible container comprises an elongated rod slidable along the rails. The collapsible container comprises a top cover mounted to the rear wall. The top cover comprises a hook and an electronic keypad electronically mounted to the hook. The front wall and the rear wall are collapsed and the sidewalls and the top cover are placed over the front wall and the rear wall to form a flat structure such that the collapsible container can be used as a floor mat. The collapsible container provides an efficient and easy to use method for a user to secure delivery packages to their front porch.

Devices and systems for collapsible engagement mechanisms are described herein. In some examples, one or more embodiments include a front panel, a first side panel connected to the front panel, a second side panel connected to the front panel, and a collapsible portion connected to at least one of the first side panel and the second side panel, where the collapsible portion is collapsible about a hinge.

A container includes a base having end edges and side edges. The base includes a plurality of regions including a center region, corner portions, side regions between the corner portions and between the center portion and the side edges, and end regions between the corner portions and between the center portion and the end edges. The center region is reinforced differently from the side regions, end regions, and corner regions. The corner regions are reinforced differently from the side regions and the end regions. The center region has no ribs protruding downwardly. A plurality of walls extending upward from the side edges and the end edges of the base.

A container includes a wall extending upward from a base. The wall includes a frame and a first wall portion pivotably connected to the frame. The wall further includes a latch selectively connecting the first wall portion to the frame. The latch is movable vertically relative to the frame to selectively release the first wall portion from the frame.

A foldable container includes a foldable supporting frame, at least one operation switch arranged on the foldable supporting frame, and a container body supported on the foldable supporting frame. The operation switch is actuated through a pulling operation to move the foldable supporting frame between an unfolded mode and a folded mode. The container has an edge and an opening formed within the edge. At the unfolded mode, the opening is opened. At the folded mode, the opening is closed. The container body is automatically folded as the foldable supporting frame is moved from the unfolded mode to the folded mode. Via a folding method, the foldable supporting frame is folded to reduce an overall size for occupying less storage space when it is not in use.

A crate includes a base and a plurality of walls extending upward from the base. A plurality of ventilation channels are formed in the base. The ventilation channels project upward relative to an upper support surface of the base. The ventilation channels include apertures therethrough.

A corrugated plastic box and a method for manufacturing a corrugated plastic box from a blank are provided. The method includes the steps of forming rounded edge seals on the perimeter edges of the blank, pre-sealing portions of the blank to form a plurality of areas in which major and minor flap slots and a glue tab are desired, ultrasonically scoring the blank to form a plurality of flap score lines, and cutting the blank through the plurality of pre-sealed flap slots and glue tab, leaving a sealed edge.

A collapsible snack caddy has an open rectangular box-like configuration for carrying snacks and a closed flat configuration. The caddy has a bottom, front and back sides, left and right ends, and an open top. The caddy is hinged at all four corners. The sides and ends are hinged to the bottom. The sides have diagonal living hinges to allow a triangular portion to fold upon the trapezoidal portion. The bottom, and both sides are hinged in the middle so that opposite portions of the ends, sides, and the bottom can fold upon each other.
