Unit for dispensing at least one fluid product, in particular a cosmetic or pharmaceutical product, having a pressure actuated, self-sealing, closure outlet |
摘要 |
The invention concerns a unit for dispensing at least one fluid product; this unit comprises at least one dispensing duct, each comprising at its end portion a closing system opening towards the outside. The closing system is formed by an obturator which forms part of a component made of an elastically deformable material and a seat which forms part of another component of the dispensing head. The obturator is in contact with its associated seat in the absence of any dispensing action, moving away from the seat by elastic deformation under the pressure of the product to be dispensed, and returning by elasticity into contact with the seat when the dispensing stops. The obturator is subjected to the action of a constraining element tending to keep it applied to the seat wherewith it cooperates.
