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 video cassette is labeled with a wrap around label attached to the cover, to the back and to the bottom of the video cassette. The label has perforations for detachment of the bottom section. A clear film can be attached peripherally around an opening in the label for viewing a reel and hub within the video cassette. Portions of the cassette are molded as openings between the interior and exterior to reduce material costs, and are subsequently covered with the wrap around label. The invention is a lower cost molded video cassette with increased display area and removable label section, which can be put to various uses, such as an information card for future reference.

Abstract: An integrally molded polypropylene tape cassette has a base with vertical first and second side walls. A rear wall is attached to the base by an integral hinge. A cover attached to the rear wall by an integral hinge, and a dust door attached to the cover by an integral hinge. Snaps between the cover and base connect and close the apparatus with integral springs pressing on tape reel hubs. The dust door covers a forward wall protruding from the base between the first and second side walls. The forward wall has slots and posts for allowing passing of the tape between the interior and exterior of the cassette. The cassette further includes a dust door latch which is integrally molded with one of the sides of the tape. An integrally molded tape hub brake is positioned between the hubs for locking the hub flanges when the cassette is not in use the entire cassette is made of polypropylene material.

Abstract: A dust door arrangement which avoids spring clip malfunction and enhances video cassette longevity. Reduced width of cavities containing first and second side hinges between the dust door and the video cassette cover improve hinge flexibility and operation and eliminate hold down spring clips catching when the video cassette is being withdrawn from a VCR. The dust door, hinge and cover are integrally molded, with the hinge lying below the surface of the cover of the video cassette and providing an axis of rotation for the door with respect to the cover. The hinge and cavity are approximately of the same width and are about two to four times as wide as the thickness of the dust door side walls. A supplemental spring is preferably provided to bias the dust door downward. The dust door first and second thin side walls have bevelled tops with extended steps which form first and second hinges. Flat tops of the hinges oppositely mate with first and second extensions extending down from the cover.

Abstract: A low cost video cassette has a base formed of a generally flat wall portion, with sloped converging front walls spaced inward from a front edge and with flat tape guiding walls extending upward from medial, generally rectangular projections of the base. Tape guide roller support pins are mounted on forward projections near lateral portions of the base. Tape reel guides are molded in the base. Integrally formed tape reel locks have operators extending into a groove formed in the plane of the base for receiving an actuator which extends into, but not beyond, the plane of the base. The rear wall has an upward-extending recess and a frangible anti-record tab extending downward within the recess. Rectangular openings are formed medially in the cover. Flaps are hinged to the openings. Cantilevered leaf springs connected along outer edges of the openings or to the flaps extend toward the base wall when the flaps close the openings to urge tape reels downward. A dust cover is connected to the short living springs.

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.
