Abstract: A die cut blank of corrugated paperboard for forming a one-piece self-locking container for a product such as computer software items. Five panels forming the top, bottom and sides of the container are in line and flaps depend from either side of one of the side forming panel and each of the top and bottom forming panels. The flaps on the side forming panel include hinged locking flaps and the flaps on the top and bottom forming panels fold inwardly; the side flaps folding around them and being locked in place by the fifth panel engaging the locking flaps. The fold line for the flaps along one side of the blank are formed by serrated score lines rupturable for removal of the one end of the container providing a self supporting file holder for the software packet. A serrated thumb hole score is provided adjacent the fold line at the top (or bottom) of the container as access to enable tearing open and removal of the one end of the container.

Abstract: A multi-compartment carton or container formed from a single blank of sheet material which is cut, scored, folded and glued in a fashion such that it is in a collapsed or "knock-down", ready-for-shipping condition upon being formed and is thereafter easily erected for use.

Abstract: An attachment or accessory, for semi-automatic firearm, comprising a housing releasably attached to the trigger guard of the firearm, a rotor member rotatably supported in the housing and having cams or lobes adapted to repeatedly actuate the firearm trigger through the intermediary of a rocker member actuated by the rotor cams when the rotor member is rotated. A lever-supported crank and a meshing pinion arrangement rotates the rotor through a one-way clutch coupling when the lever is displaced in one direction, the one-way clutch coupling disconnecting the rotor from the pinion when the lever is displaced in an opposite direction to a return position.
