Energy absorbing video cassette

摘要

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.
