ABSTRACT:
The flexible inner pouch is fixed in a leaktight manner by its neck to a rigid ring having peripheral means for fastening on the neck of a rigid bottle accommodating the flexible pouch and an inner tubular part with means for fastening on a central tubular part of a pump body, a seal ensuring leaktightness between the two tubular parts, independently of the means for fastening the pump on the ring. A circuit for air intake into the volume between the pouch and the bottle may comprise an air passage formed in the pump body and closed by confinement means when the pump is not actuated by operating a plunger.
