Disperging head having a closing system with air suction

摘要

A delivery head (102) comprises a delivery tube (103) and a closure assembly allowing recovery of air to close the end portion of the delivery tube which leads to the exterior. The closure assembly is formed from a closing device (105A) consisting of an elastic lever of elastically deformable material and a seat (115) consisting of a rigid material member. The deformable material is at least partly integral with the rigid material member (117). The closing device (105A) being in contact with its associated seat (115) when there is no product being delivered, disengages from the seat through elastic deformation from the force of the product being pushed through to the exterior and returns to a position which allows the intake of air, when force from the product is removed. The seat has a small lump which prevents the elastic member from returning to a completely flat position. Also claimed is a product container equipped with the delivery head.
