ABSTRACT:
An assembly for dispensing a fluid product includes a container and a dispensing head with a channel for dispensing product. The head is rotatable and includes alignable orifices for fluid communication with the container via the dispensing channel. A closure is located at a terminal part of the channel. The closure includes a flexible flap at least partially closing the terminal part, when dispensing is not taking place, moving away at least partially from the closing position by flexing under the pressure of the product being dispensed, and returning, by elasticity, to the closing position, when dispensing ceases. The flap is normally urged into the closing position by a stressing member, which is a heel formed continuously with the flap and connected in the dispensing head.
