Abstract: Tape partially curves around a one-way tape brake for a cassette. The brake has a cylindrical roller with a side extension. When the tape advances, a smooth cylindrical side of the roller allows tape forward movement. When the tape tends to reverse the tape pulls a friction surface rearward, turning the roller and frictionally engaging the tape and pinching it against a tape guide. Rearward tape motion is prevented.

Abstract: A new CD package has a cover attached to a tray by a single hinge at one end of the tray. That simplified manufacture and assembly makes the entire cover available for printing and graphics. The CD package is assembled with a single direction motion of a paper board cover toward a plastic tray. The entire cover surface is available for graphics, and the complete package lies flat on either side when fully or partially opened. A hook folded on one paper board flap engages a ledge in the receiver. A flap on one paper board cover is slit and glued or physically attached to a hinged extension on the tray. When the flap is formed on one end of the cover, the cover wraps around the tray. When the flap is formed in the middle of a cover, the CD package opens like a book. More than one connector flap may be provided for connecting the cover to multiple trays. The trays may be double-sided with a central opening in a central platform to receive snap-in and twist-in rosettes.

Abstract: An integrally molded video cassette is formed with an integral living hinge between the body of the cassette and the dust cover. An energy absorption zone formed near the hinge isolates the hinge from directly transferring high impact forces between the relatively low mass dust door cover and the high mass cassette body loaded with reels and tape. Energy absorption zones are formed of relatively thin wall areas with radiused intersections. One or more radiused grooves are formed in the wall sections.

Abstract: A cutter for removing overwraps or tape on products and product packages incorporates first and second wings extending angularly from a body. A cutting point extends a short distance into the angle between the wings, wherein the wings embrace an edge of a product and the blade slices the wrapper along the edge as the user slides the cutter along the edge. The wings are flexible to conform to the angle of the edge, and are integrally molded with the body. Living hinges provided between the wings and the body, or the wings are molded angularly with respect to the body. A cutter is molded as a flat blank and folded. A solid article is molded with a pocket for insertion of the blade. The angle between the wings is less than or equal to 90.degree., allowing it to conform to most standard packages. The reduced angle between the wings and the relatively slight exposure of the blade allows for effective cutting of the wrapper without scarring the package or injuring the user.

Abstract: Brake levers are molded in place through an opening in the base of a video cassette. The brake levers have first brake arms with outward extending reel grippers at distal ends, and second actuator arms with an actuator connected between distal ends of the actuator arms. Medial portions of the levers are supported on integrally formed living hinges with axes perpendicular to the base. Pressing outward on the actuator arms with the actuator rotates the levers about the hinges so that the brake arms and grippers are withdrawn from contact with the reels. The actuator has two legs which are joined centrally by a hinge and which extend angularly to living hinge interconnections with the actuator arms. As a pin or blade pushes on the central connection in a direction parallel to the hinge axes of the operating levers, the actuator legs spread forcing distal ends of the actuator arms apart and distal ends of the brake arms and the grippers together, releasing the reel brake.
