Abstract

A self-closing closure, comprising a first closure member (17) having a diaphragm (20, 21) with an outlet opening (22) and a second closure member (1) having a stem (10, 11) provided to cooperate with the outlet opening has an attachment portion (6) for connecting the closure to the outlet portion of a tube or similar package and said attachment portion is separated from the outer portions of the closure by means of an annular wall (5). An annular space is provided between the outlet portion of the tube and the outer portion of the closure to allow air to pass and reach an opening (12) provided in the wall to establish a communication between the interior of the closure and the free air. A valve means in the shape of a valve member (23) made from a rubber-like material and having a funnel-shaped portion (25) sealingly inserted in said opening (12) and a shaft portion (24) serving to guide the valve member serves to allow suction of air into the closure when a negative pressure exists in the latter. The closure may also have means to lock the same against unintentional opening.
