A cap for a container having a screw threaded opening comprising an inner part (1) in the form of a screw threaded cap, an outer part (2), biased therefrom in a first, locking position, by means of resilient biasing means (3) located between the inner and outer parts, a projection (4) located on the inner part (1) and adapted to be received in an aperture (8) formed in the outer part (2), and a tamper-evident member (6) secured on the outer top surface of the outer part (2) such that it substantially covers the aperture (8), wherein on first removing the cap from the container the outer part (2) is moved into a second, unlocking position, against the biasing, the projection (4) being received in the aperture (8), and projecting therebeyond, such that at least a portion of the tamper-evident member (6) is ruptured.
A cap for a container having a screw threaded opening comprising an inner part in the form of a screw threaded cap, an outer part, biased from the inner part in a first, locking position, by resilient biasing means located between the inner and outer parts, a projection located on the inner part and adapted to be received in an aperture formed in the outer part, the cap also comprising a tamper-evident member secured to the outer top surface of the outer part and having a portion that substantially covers the aperture, wherein on first removing the cap from the container the outer part is moved into a second, unlocking position, against the resilient biasing means, the projection being received in the aperture and projecting therebeyond, such that at least a portion of the tamper-evident member is ruptured wherein the tamper-evident member is selected from the group consisting of a paper film and label secured on said outer top surface.
A container equipped with a cap, said cap having a screw threaded opening comprising an inner part in the form of a screw threaded cap, an outer part, biased from the inner part in a first, locking position, by resilient biasing means located between the inner and outer parts, a projection located on the inner part and adapted to be received in an aperture formed in the outer part, the cap also comprising a tamper-evident member secured to the outer top surface of the outer part and having a portion that substantially covers the aperture, wherein on first removing the cap from the container the outer part is moved into a second, unlocking position, against the resilient biasing means, the projection being received in the aperture and projecting therebeyond, such that at least a portion of the tamper-evident member is ruptured wherein the tamper-evident member is selected from the group consisting of a paper film and label secured on said outer top surface said portion of the tamper evident member which overlies said aperture consisting of a pattern of interlocking perforations, and a plurality of radial slits extending from said pattern of perforations towards the periphery of the tamper-evident member.
