A container assembly includes an outer shell forming an interior cavity, an inner tray dimensioned to be received within the interior cavity of the outer shell, wherein the inner tray is rotatably coupled to the outer shell and configured to rotate between an open configuration and a closed configuration. The container assembly further includes a plurality of gripping members disposed within the inner tray, the gripping members being structured to flex outwardly to receive an item placed in the inner tray and apply an inward force to the item to releasably secure the item within the inner tray.

A fishhook carrying device has a resilient prismatic block, of which two adjacent faces are cut into by at least one set of spaced grooves extending along a longest dimension thereof. Two opposite parallel grooveless faces thereof abut two rigid exterior walls, which, along with a connecting bottom wall, form a unitary box structure. Rigid exterior walls of either side of the box structure maintain the prismatic block in a compressed form such that interior walls of each groove are pressed against each other in a first resting condition. When a flange is inserted into a pressed groove, the interior walls of the groove resiliently separate and thereafter abut the flange, frictionally holding the flange in place. The interior groove walls return to the first resting condition upon removal of the flange from the device.

A packaging tray for caps includes a generally plate-shaped base having an upper face and a lower face extending along a main plane (x,y); a plurality of abutments, each abutment being configured to be in contact with a cap when a plurality of caps is held on the side of the lower face of the base; and a plurality of fastening systems, each fastening system being associated with an abutment and being configured to hold a cap against the abutment. Each of the abutments is connected to the base by flexible bridges enabling the abutment to move perpendicularly to the main plane (x,y).

Structures and a method for restraining a package within a returnable shipping container are provided to eliminate the need for buffering or filler materials (dunnage), particularly those materials that are environmentally unfriendly and otherwise likely to be discarded. Desirable shipping containers intended for reuse are provided with various features which enhance their utilization in a cycle of transportation out from and back to a source. These features include those associated with security, integrity, protection from the environment, addressing, automation, payment, inspection, education in volume for return, facilitation for tracking the container throughout the transport route and assurance of its eventual return.

A container for holding food item(s). The container having a base, a cover, and a tray. The base includes base receptacle(s), and an inner base volume is defined in each base receptacle. The tray includes tray receptacle(s), and each tray receptacle includes tab(s). An inner tray volume is defined in each tray receptacle of the tray receptacle(s) that is configured to receive a food item of the food item(s). The tray is positioned between the cover and the base when the container is in a closed state so each tray receptacle is received in the inner base volume defined a respective base receptable. Tab(s) are configured to move to an extended position when the container is in a closed state so that tab(s) contact the food item received in the inner tray volume defined in each tray receptacle, thereby restricting movement of the food item(s).
