Delivery system for being mounted on container of bottle for distribution of lacquer utilized in e.g. pharmaceutical treatments, has air supply path including downstream end that emerges directly to spraying zone

摘要

The system has a pushbutton (4) actuating a pump in translation with respect to a sleeve (5) on a path of distribution/aspiration of a fluid product. A piston (25) is moved in translation by the pushbutton and placed in the sleeve to define an air chamber (26) whose volume is decreased during distribution or increased during aspiration of the product. An air supply path includes an upstream end in communication with the air chamber through a valve (41) for initiating the communication to the distribution path, and a downstream end emerging directly to a spraying zone (18). An independent claim is also included for a fluid product distribution bottle.
