In a firearm gun grip, the rigid front force of the gun grip is replaced with a sliding grip panel, which inserts into a conjugate panel recess in the gun grip. The panel recess contains multiple coiled compression springs, which extend between the interior forward end of the grip panel and the rear surface of the panel recess. The compression of the springs, under the inward constrictive force of a shooter's hand on the gun grip, produces an opposing outward expansive force, which changes in response to the degree of insertion of the grip panel into the panel recess, thereby serving to stabilize the gun grip and improve aiming accuracy.

A multi-layer sheet for forming an expanded foam container, the multi-layer sheet including a first layer of an expanded foam material including a first polyolefin-based material including at least one polypropylene-based polymer and a second layer of an unexpected material including a second polyolefin-based material including at least one polypropylene-based polymer that is co-extruded, extrusion coated, or laminated on a first side of the first layer.

Insulated container and methods of making and assembling

A container having tamper evident and resistant features comprises a tray having a bottom wall and a peripheral side wall extending upwardly from the bottom wall, which collectively define a compartment, and terminating in a tray rib to at least partially define an open top providing access to the compartment. The container further comprises a cover comprising a top wall that terminates in a cover rib having a peripheral cover lip, an interference element extending from the container, at least one tab provided in the container and associated with the interference element, and at least one line of weakness coupling the tab to the container. The tab is moveable between a first position where the line of weakness is not severed and a second position where the line of weakness is severed.

Tamper evident and resistant container

A container having tamper evident and resistant features includes a tray, a cover, and a blocking wall that prevents direct access to a peripheral cover lip of the cover when the cover is in a closed position on the tray. The container includes at least one tab that prevents direct access to the peripheral cover lip and which is at least partially separable from the container along at least one line of weakness to provide access to the peripheral cover lip for removing the cover from the tray. The tab further includes an interference element that inhibits replacement of the tab into its original position with respect to the container after the at least one line of weakness have been severed.

A method and apparatus for extruding a corrugation-free polystyrene foam with 100% carbon dioxide as the blowing agent by extruding the extrudate through an annular die opening so that it contacts a choke ring inner surface. A foam made with the apparatus according to the invention will have no visible corrugations and an average cell size of less than 0.35 mm.

Apparatus for making a corrugation-free foam

A method for extruding a corrugation-free polystyrene foam with up to 100% carbon dioxide as the blowing agent by extruding the extrudate through an annular die opening so that it contacts a choke ring inner surface. A foam made with the apparatus according to the invention will have no visible corrugations and an average cell size of less than 0.35 mm.

Process for making a corrugation-free foam

A thermoplastic foam comprises a styrenic polymer and a blowing agent consisting of 100% carbon dioxide. The thermoplastic foam has no visible corrugations and an average cell size of 0.20 mm to 0.35 mm.
