Abstract
A head for manufacturing a flexible tube is described. The head includes a pump and a shoulder. The pump includes a pump mechanism equipped with a piston sliding axially in a pump body and a push button mounted on the piston and equipped with a dispensing orifice for dispensing the product sucked by the pump. The shoulder is a single-piece component which is delimited externally by an annular peripheral bearing face. The bearing face surrounds a visible segment equipped with a central orifice, where the pump body is configured to be mounted. The shoulder includes a ring formed by an annular wall which extends axially upwards surrounding the central orifice to receive the push button and guide its sliding.
