A method of manufacturing a custom sized plastic tote lighter in weight than heretofore known custom sized plastic totes is provided. The method comprises separating an injection molded tote into upper and lower portions by cutting the injection molded tote. A sleeve or middle portion of plastic material is secured to the upper and lower portions of the injection molded tote to create a custom sized plastic tote of a desired height. Alternatively, portions of different injection molded totes may be used to create a custom sized plastic tote. The sleeve may be made from different materials and may be made of multiple pieces.

A method of manufacturing a composite panel includes manufacturing a composite panel having a first skin, a second skin, a core, and a plurality of distinct groupings of Z-axis fibers that extend through the core from the first skin to the second skin, wherein the Z-axis fibers include opposite ends respectively terminating at and integrated into the first skin and the second skin; and creating structural stringers in the composite panel by removing the second skin and substantially all of the core and the Z-axis fibers down to or adjacent to the first skin.

A cooler for providing side compartments for holding ice separate from an inner container for holding food and beverages. The cooler includes an outer chest with an open top and an outer lid covering the open top. An open inner frame is position in the open top of the outer chest and spaced apart from the outer chest. The inner frame has a plurality of outwardly extending generally connecting tabs coupled to the outer chest to connect the inner frame to the outer chest. Each adjacent pair of connecting tabs define therebetween a passage between the inner frame and the outer chest. An inner container is provided in the outer chest and is positioned in the center hole of the inner frame. The inner container is spaced apart from the outer chest to define an outer reservoir therebetween.

A process for the production of chlorofluorocarbon-free, urethane- or urethane- and urea-containing, soft-elastic, semirigid or rigid moldings having a cellular core and a compacted peripheral zone and an essentially pore-free, smooth surface involves reactinga) an organic and/or modified organic polyisocyanate withb) at least one relatively high-molecular-weight compound containing at least two reactive hydrogen atoms, and, if desired,c) a low-molecular-weight chain extender and/or cross-linking agent,in the presence ofd) a blowing agent,e) a catalyst,f) at least one microporous activated charcoal and/or microporous carbon molecular sieve which preferably has a mean pore diameter with a frequency of occurrence of more than 40% in the range from 0.3 to 3 nm, a pore volume of from 0.20 to 1.4 ml/g and a BET surface area of from 500 to 2500 m.sup.2 /g, and, if desired, further additives andg) assistants,in a closed mold with compaction.

A board game box comprising two base frames made from a plastic material through the process of injection molding and pivotably connected with each other by hinges, said base frames each having an opening at the middle, a groove around said opening and a plurality of projecting strips transversely projecting in said opening at one side above said groove, two veneered panels respectively fastened in said groove and retained in place by said projecting strips, two lining sheets respectively glued to the surface of said two veneered panels, locking devices fastened in said base frames for locking them into a closed position, and a handle attached to either of said base frames for comfortable and positive grip. Each base frame has two locating grooves at two opposite locations for fastening a small storage case for keeping the pieces for a board game.

The rib form comprises a cardboard blank folded into a trapezoidal shape and having overlapping opposite longitudinal edge portions of the blank glued together and forming the shorter of the two parallel sides of the trapezoidal shape. Peripheral slots evenly spaced along the rib form are cut through the longer of the parallel sides and through the two angular sides of the trapezoidal shape.
摘要:
A large volume metallic composite container consisting essentially of a plurality of metal plates welded end-to-end, each said metal plate having a stainless metallic layer on the periphery of at least one side thereof and on the ends thereof and a heat-sensitive anti-corrosion coating consisting essentially of a thermoplastic resin on at least one side of each said metal plate and overlapping said stainless metallic layers over a length of at least about 10 mm and at least about 10 mm from the weld used to weld the plates together. The process of making of such containers is also disclosed.
摘要:
A process for the preparation of laminates comprising the steps of (1) putting a thermoplastic resin sheet or film and a metal foil or sheet one upon another with a specific polyolefin type resin being interposed therebetween, (2) heating the thus interposed specific polyolefin type resin to a temperature not lower than the melting point of the specific polyolefin type resin to obtain an intermediate laminate and (3) laminating at least one of thermoplastic sheets or films and paper on the metal foil or sheet side of said intermediate laminate using therebetween an ordinary adhesive not requiring heating at a temperature not lower than said melting point at the time of lamination thereby to obtain a desired laminate. In one embodiment, this invention also relates to a foodstuff packaging container wherein the innermost layer is a polyolefin resin sheet or film.
摘要:
A packing comprising an outer cover constituted by a relatively rigid material and an inner container of relatively flexible material placed within the outer cover. A perimetral rim portion is formed on the outer cover at one end with a central opening within the rim. A plate is disposed within the rim to define a narrow gap therewith extending around the periphery of the plate. The plate is constituted of the same material as the outer cover and is affixed at its inner surface to the outer surface of the inner container by glue or other suitable expedient. The cover can be removed by cutting the inner container at the gap to expose the contents in the inner container.
