Abstract: A collapsible container for containing goods, including a liquid and/or solid/liquid mixture, configured to be assembled and disassembled manually without the use of tools. The container includes a plurality of upright panels coupled to a base by their bottom portions. Each panel of a first type is flanked along its opposing upright edges by a pair of adjacent panels of a second type. Each of the edges of each of the panels is coupled by an edge joining assembly to one of the edges of one of the flanking panels. The assembly comprises a first elongated edge joining member having a longitudinal channel with alternating partially enclosed portions and substantially unenclosed portions and a second elongated edge joining member having longitudinally extending spaced apart locking members. Each unenclosed portion is configured to receive a locking member, which are slid longitudinally within the channel into an adjacent partially enclosed portion.

Abstract: A collapsible container for containing goods, including a liquid and/or solid/liquid mixture, configured to be assembled and disassembled manually without the use of tools. The container includes a plurality of upright panels coupled to a base by their bottom portions. The bottom portion of each panel has a relieved portion that extends into a corresponding groove formed in the base. The panels include panels of a first type and panels of a second type, with the relieved portion of the panels of the first type differing from the relieved portion of the panels of the second type. Each panel of the first type is flanked along its opposing upright edges by a pair of adjacent panels of the second type. Each of the edges of each of the panels is coupled by an edge joining assembly to one of the edges of one of the flanking panels.

Abstract: A commercial fishing net takes advantage of animal psychology to easily permit the escape of entrapped porpoises while preventing the escape of desired tuna and other edible fish, the net having at least a portion comprising a drop net which sinks beneath the water surface to a depth defined by tethered floats when a control bladder attached to the top of the drop net is deflated, there also being an optional stiffener hose extending along the top of the drop net and being filled with a releasable pressurized fluid to maintain the upper edge of the drop net aligned and prevent the bunching of this net portion.

Abstract: The invention is a ballpoint pen characterized by a generally teardrop-shaped planar casing defining an arcuate channel therein to receive a conventional, flexible ink cartridge in a compact configuration, this casing having a key-chain hole therein and a retractor button disposed on one side or edge thereof.
