Abstract: Static electric charge build-up is eliminated in tape cassettes having a housing with a take-off spool and a take-up spool for magnetic tape mounted in the housing. First and second tape guide support pins are mounted in the housing on the take-off spool side. A stationary metal guide sleeve is disposed on the first pin and an electrically conductive plastic guide roller is rotatably mounted on the second pin. The magnetic tape path through the cassette housing is such that the back side of the tape engages the metal guide sleeve and the magnetic coating side of the tape is against the plastic guide roller. A smooth flat metal member is mounted for electrical contact against adjacent ends of the metal sleeve and the plastic roller to complete an electric path therebetween. This cancels the electrostatic charges on the plastic roller and the magnetic coating of the tape.

Abstract: A container with a pivotal closure member and latching means for said closure member is disclosed. The latching means includes a female part defining an entry leading to an enlarged area relative to said entry, and a compressible male part sized and shaped to occupy said enlarged area after being compressed through said entry, the female part being mounted on one of said container and closure member, and the male part being mounted on the other of said container and said closure member.
