Dispensing closure with tamper-evident push-button

Abstract

A closure includes a closure body having a deck and a circumferential skirt. An opening is formed in the deck and a receiving recess is formed in the circumferential skirt or in the deck. A lid is hingedly connected to the closure body, and a tamper-evident push-button is formed in one piece with the lid. The lid and the push-button are connected by frangible connections. The tamper-evident push-button is received in the receiving recess upon first time closing of the lid. The receiving recess is adapted to allow the tamper-evident push-button to be pushed whilst in the receiving recess so as to break the frangible connections and allow opening of the lid. The push-button has a coupling member to couple the push-button to the closure body. The coupling member provides a tilting axis allowing tilting movement of the push-button with respect to the closure body when it is pushed in.
