A container closure and methods are disclosed for providing visible evidence of removal of the closure from a container after installation by a manufacturer. The closure includes tamper evidence bridges comprising small tabs of material that extend from a bottom-most edge of the closure to a tamper evidence ledge of the container. The bridges break when the closure is rotated relative to the tamper evidence ledge, thereby providing readily visible evidence that the closure has been removed after installation by the manufacturer. In some embodiments, a tamper evidence closure engages with threads of a finish of the container. Cam locks around the perimeter of the tamper evidence closure are permanently flared by cams on the finish during loosening of the closure. Outward flaring of the cam locks provides a visual indication that the tamper evidence closure has been loosened after installation by a manufacturer.

In consumer-market containers for beverages or other contents under pressure, the cap provides a gas-tight seal by way of two mechanisms that work interdependently. The first is a pressure grip configured to grip at least one of a) the inside wall of the container and, b) the outside wall of the container. The second is twist threads, or some other second attachment structure, that urges the inside of the cap (or, typically, a cap liner disposed thereon) against the rim of the container. Release of pressurized gases when the container is first opened can be by way of release vents in the cap, or via the bottom of the cap through the twist thread area. In the latter case, particular configurations of the pressure grip are relied on to establish the gas escape path.

The present disclosure provides a threaded cap (11) and neck (12) set for evidencing tampering with container (13), comprising a neck (12) of a container (13) having a cylindrical shape and an aperture at its top end, the neck (12) having threads on its outer surface and a sealing collar (14), the sealing collar (14) comprising a plurality of teeth (15) and a cap (1) having a cylindrical shape and having threads on its inner surface, the cap (11) including a tamper-evident ring (16) attached to the lower rim (17) of the cap (11), said tamper-evident ring (16) having a diameter longer than the diameter of the cap (11). The tamper-evident ring (16) comprises multiple reversible grippers (18) projecting longitudinally from the lower rim (17) of the tamper-evident ring (16), wherein the reversible grippers (18) are coupled to the lower rim (17) of the tamper-evident ring (16) by a hingeable membrane.

The closure device for bottle comprises an inner sleeve with locking means on the bottle, a cover with tear-off element, coupled to the inner sleeve, wherein said cover is connected with the tear-off element by a weakened section. The inner sleeve is a hollow cylindrical element with open butt ends, outer projections are formed on the lower part of the sleeve and the tear-off element is formed with inner projections for coupling with the outer projections of the sleeve. The inner sleeve comprises an annular element arranged on its inner surface which can provide additional visual tamper-evident through the outer side surface of the inner sleeve.
