Abstract:
A dispensing device for liquid, fluid or pasty products. A support in an opening of a receptacle encloses the product. The support has a central tubular conduit, a pushbutton axially slidably mounted on the support between a rest position and an active position and a product outlet conduit. An intermediate piece of a resiliently deformable material is between the support and the pushbutton. The intermediate piece and the pushbutton define a measured quantity chamber for the product. The intermediate piece has an opening for communication between the tubular conduit of the support and the measured quantity chamber, and sealingly bears against at least one opening for passage between the measured quantity chamber and the outlet conduit of the pushbutton.
