Bottle for distributing e.g. liquid product, has valve filling tank and allowing communication between product source and outlet tank to allow suction of product from product source in tank by elastic return of tank at dilated state

摘要

The bottle has a tank (1) conditioning fluid product and arranged around a tube (10). The tank includes an upper span (12) and a lower span (13) between which the tank is elastically deformable between a dilated state at rest and a constrained contracted state. The spans are fixed in a tight manner around respective upper and lower parts of the tube. A filling valve (23) fills the tank, and is arranged to allow communication between a product source and an outlet tank by elastic return of the tank at the dilated state to allow suction of the product from the source in the tank.
