Abstract: Plastic bottle caps of the snap-on type having tamper indicating means such as a tear band. The top wall of the top overhangs its side wall and the overhanging lip is filleted at an angle of about 30.degree. to increase the difficulty of removing the cap by hand without visibly affecting the tamper indicating means. Also, the cap has interior interrupted beads for snapping over the shoulder of the bottle neck and has ribs in the interruptions for adjusting the magnitude of the snap-on and snap-off forces. The cap is molded on a core having grooves for forming the beads and ribs. The cap may have a non-resilient gasket and a dished top so that it can exert pressure on the gasket. A foil seal having adhesive on one surface may underlie the gasket. After the cap has been applied to the bottle neck, the foil seal may be caused to adhere to the bottle neck.

Abstract: A container closure attachable directly or indirectly to a container neck sealed by means of a pierceable film seal. The provision of a film seal covering the container neck guarantees the user that the contents of the container are authentic and original as supplied by the manufacturer. The film seal is pierced as the closure is adjusted from an intact to an access position on the container neck. In the upper intact position, a safety band remains intact. The closure can be adjusted to the lower access position only after the safety band has been removed, and the film seal is pierced as the closure is adjusted to the lower access position. Ratchet-like serrations may be provided on the inner side of the safety band engaging the container, thus making it impossible to unscrew a screw-type closure without removing the safety band. The safety band may be provided on a separate intermediate piece which may be snap-fitted or screwed onto the container neck.

Abstract: A sealing device for containers which forms a valve for automatic elimination of overpressurized gases that may form with the container is provided. The device is composed of a rigid cap having a flat crown and depending skirt, an elastic disk sector in contact with the underside of the flat crown and an inner cap having a circular crown with a circular cutout and raised circular rim on an upperside thereof. A flat circular protuberance on the underside surface of the disk sector, when the device is in use fits into and is surrounded by the circular crown portion, both of which are adapted to fit vertically over the orifice of the container. When in use, the circular crown exerts a crushing pressure on the upper portion of the elastic disk sector while at the same time the flat circular protuberance remains sufficiently elastic to allow gases overpressurized to vent from the container.
