Container for dispensing fluid product e.g. liquid product, has piston whose head fixes closure member with closure flange of inner outlet of pipe on chamber of tank, where chamber houses piston in elastic mobility

摘要

The container has a tank (1) provided with a product receiving chamber (3) that houses a piston (2) in elastic mobility. The piston has a head (14) provided with a closure member (18) of an outlet (8) opened towards an exterior of a product delivering pipe (4) that delivers a product outside the chamber. The head is operated between a spontaneous closure position of the pipe and a retraction position by a deformable unit (15) interposed between the head and a support unit (17). The head fixes the closure member with a closure flange (19) of an inner outlet (12) of the pipe on the chamber.
