Abstract
Products having a viscous or pasty consistency, or those dispensed as foams from a container (1) provided with a pushbutton (13) the actuation of which causes the ejection of a dose of product, are never, in practice, completely evacuated from the ejection conduit (14) made in a movable portion (9) bearing the pushbutton (13) and adapted to the outlet of the container (1). Hence they often threaten to escape from this conduit (14) and soil the container (1). To overcome this disadvantage, the invention proposes that the conduit (14) discharge into a chamber (40) defined by a fixed portion (10) attached to the container (1) and with the movable portion (9) comprising a dispensing cap (8); the chamber (40) opens to the outside via an opening (38), and the movable portion (9) includes a needle (27) capable of closing this opening (38) in the position of repose of the pushbutton (13) and of freeing it upon actuation of the pushbutton.
