Abstract: There is disclosed a tamper-evident device for a closure assembly adapted to be applied to a mouth of a container, for example, a neck of a bottle. There has been identified a need for an improved tamper-evident device which does not have any parts which are removed upon initial opening and which are liable to be reattached by counterfeits or the like. Accordingly the present invention provides a tamper-evident device comprising a sleeve member which comprises a first portion associated with a second portion by a frangible portion therebetween, and wherein said first portion is adapted to be applied to a mouth and neck portion of a container, and said second portion is associated with a container closure member, and wherein an initial container opening operation causes said frangible portion to fracture or break such that when the container is reclosed said first and second portions are located in a spaced apart relationship to one another.

Abstract: A closeable dispensing device for dispensing a liquid, viscous or pasty medium contained in a container has a first opening for dispensing the medium located in the container, a second opening for ventilating and/or venting the container, and a closure device which can be actuated in order to produce and break a connection between the first opening and the container and between the second opening and the container. The dispensing device described is distinguished in that the closure device is designed such that, when actuated as is required in order to produce a connection between the first opening and the container, it first of all produces a connection between the second opening and the container and only then produces the connection between the first opening and the container. Such a dispensing device is straightforward to use and, nevertheless, cannot under any circumstances open of its own accord.
