发明名称 Tamper-proof closure
摘要 The invention contemplates a container closure, with a frangible cover preassembled thereto, such that both the closure and the cover have independent snap-lock engagement to the container-neck finish, in a single axially displaced assembly of both of the preassembled parts to the neck finish. The cover must be broken to gain access to container contents, so that any breakage provides a direct warning as to possible tampering. In the disclosed embodiment, the closure which remains after destruction and removal of the cover, has child-safety features, in respect of its snap-action engagement to the neck finish.
