Abstract:
Assembly for dispensing a fluid product from a container, comprising:(a) a dispensing head to be connected to the container and including a channel for dispensing the product, the dispensing channel including a terminal part opening to outside of the dispensing head,wherein the dispensing head includes a support by which the dispensing head is mounted on the container, and a member movably attached to the support,wherein the channel includes a passage in the support, and a passage in the movable member, andwherein the movable member is movable between a first open position at which the passage of the movable member and the passage of the support are in fluid communication, and a second closed position at which the passage of the movable member and the passage of the support are not in fluid communication; and(b) a closure member made of an elastic material, having a first portion, and a second portion formed continuously therewith, a flexible flap at the first portion, and a stressing member for the flap in the form of a heel at the second portion being made one piece with the flap, being spaced from the flap and being attached to the movable member,wherein the flap is movable between a first position at least partially closing the terminal part of the channel, when dispensing is not taking place, the stressing member normally keeping the flap in said first position due to the elasticity of the closure member material, and a second position wherein the flap is spaced from the dispensing head by flexing under pressure of the product being dispensed, and the flap returning, by the elasticity, to the first position, when dispensing ceases.
