  • Patent number: 4934546
    Abstract: A snap-on, tamper evident plastic cap for a plastic bottle neck has a skirt with upper and lower internal locking beads which lock under extenral beads on the neck. The cap is not removable so long as the skirt is intact. The lower end of the skirt, including the lower bead, may be torn off to permit the cap to be removed. To facilitate removal, the cap skirt is formed with a score line which slants upward from the lower edge of the skirt to merge with a circumferential score line which terminates near the origin of the slanted score line. A third score line extends from the terminus of the circumferential score line down to the lower edge of the skirt. Thus there is a tab (a remnant of the original skirt) between the first and third score lines which functions as a lift tab.

  • Patent number: 4930655
    Abstract: An easy-open beverage container with a non-detachable closure assembly includes a container body and integral end wall. In one embodiment, the end wall is formed to defined an opening through which the container contents can be dispensed and a threaded lip extends about the periphery of the opening. Another embodiment reveals that the wall contains a selectively separable region of predetermined weakness defining an openable panel in the wall. An opening and reseal cap has a depending threaded skirt adapted for operative engagement with the threaded lip of end wall. The cap can be threaded onto the lip to seal the can or unthreaded to open up the can for use. An arm is pivotally attached at one end to the can end wall and the cap is rotatably attached to the other end of the arm such that the cap is non-detachably mounted to the end wall through the arm. The cap can thus be unscrewed to open the container and the cap and arm pivoted to displace the cap from the opening for dispensing the container contents.

  • Patent number: 4923073
    Abstract: A tamper-indicating plastic closure is shown which is configured for mechanical interference with the annular locking ring of an associated container. The closure includes a top wall portion and depending skirt portion, with a circular pilfer band at least partially detachably connected to the skirt portion by a plurality of circumferentially spaced fracturable bridges. Notably, the pilfer band includes an internal, annular interference lip which is skewed or arranged at an angle relative to the vertical axis of the closure. By this construction, the interference lip engages the container locking ring during closure application so as to deform the closure to a non-circular configuration, thus minimizing stressing of the fracturable bridges. During closure removal, the angular configuration of the interference lip creates localized stressing of the fracturable bridges, thus providing serial fracture of the bridges.
