ABSTRACT:
Assembly (1) for dispensing at least one liquid product or a product in the form of a cream. The assembly comprises a container (2) to which is fixed a distributor head (3) comprising at least one delivery channel. The end of the delivery channel is closed according to the invention by means of a closure system (F) comprising a valve (51) of flexible material which cooperates in the rest position in a non-sealed manner with a fixed rigid seating (41). The valve (51) moves away from the said seating (41) during dispensing by elastic deformation as a result of the pressure of the product to be dispensed, then moves into a position allowing for air recirculation when dispensing is completed. The assembly (1) may comprise, upstream of the closure device (F), a safety device for interrupting the communication between the container (2) and the closure device (F).
