Nozzle closed by a membrane for dispensing containers.

摘要

Nozzle closed by a membrane for compressible dispensing containers, particularly tubular containers. Radial weakening lines (18) defining a plurality of sectors (19) in the membrane closure (14), and stop buttons (21) provided projecting from the dorsal face of at least some of these sectors (19) are adapted so as to interact with a view to locking by means of nesting with openings (22) hollowed out in the internal wall of the nozzle. Application to the manufacture of a nozzle closed by a membrane by means of moulding in plastic materials.
