A CLOSURE ASSEMBLY COMPRISING A CAP WITH AN INTEGRATED TAMPER-EVIDENT RING MEMBER

A closure assembly comprises an article and a cap provided with an integrated tamper-evident ring member. The article further comprises a circumferential flange structure with an annular flange portion and a peripheral protective rim portion so that the top face of the flange portion and the protective rim define an annular recess around the neck. The tamper-evident ring member is integrally formed to the lower edge of the skirt of the cap via one or more breakable bridges. The ring member comprises an annular ring member flange portion that has a top face and a bottom face. Multiple hook members are integrally formed to the bottom of the ring member flange portion, and the annular flange portion on the neck is provided with multiple hook member passages. Each hook member passage is adapted to receive a hook member when the cap with the integrated tamper-evident ring member is axially mounted on the neck by means of an axial securing motion, wherein the hook portion of each hook member snaps underneath the bottom face of the annular flange portion on the neck of the article. The leg of at least one hook member has an inner bevel face at the lower end thereof. The neck is integrally formed with a corresponding bevel faced boss at a location below the corresponding hook member passage. Upon axially mounting the cap with the integrated tamper-evident ring member on the neck the bevelled face of the boss contacts the inner bevel face of the leg.
