Snap-on closure with discontinuous annular lip

Abstract: There is disclosed a snap-on closure for containers, such as milk and soft drink plastic bottles, which has upper and lower annular beads on the inside wall of a peripheral skirt with a tear band defined by a score line in the skirt, located between the annular beads. The score line extends towards, but not entirely to, the bottom edge of the skirt, terminating a short distance above the bottom edge of the skirt. This score line permits a tearing of the lower portion of the cap skirt from the closure, and for this purpose, the cap tears along the weakened score line, about the closure and then downwardly towards the bottom edge of the skirt so that the entire lower portion of the skirt is removed as a tear band, leaving only the reclosure on the bottle. Since the lower score line does not extend to the lower edge of the skirt, that lower edge is not weakened, but retains its full hoop strength, to resist splitting when the cap is applied to the bottle.

Coin operated video machine

Abstract: A coin operated video machine is provided, of the sort intended for stand-alone operation in shopping malls and the like. The machine includes a tape player with a tape playing mechanism, a coin operated switch, and a television monitor. Upon actuation of the coin operated switch, pre-recorded program material is viewed on the monitor. A plurality of discrete video programs is recorded seriatim on the video tape, each having a control track; and between each pair of pre-recorded video programs there is a non-program passage. When the non-program passage is encountered, the tape playing mechanism stops; and a new play mode is not initiated until the coin operated switch is once again actuated. The tail end of the video tape is such that when encountered, the tape playing mechanism will go into a rewind mode; and the front end of the tape has at least a short pre-recorded program material and control track so that, upon termination of the rewind mode a play mode is immediately initiated. Program material of any kind for which a prospective viewer will pay a nominal amount in coin to view may be pre-recorded on the video tape.
