Dispensing bottle comprising a pump with purge membrane

摘要

The bottle has a body (1) defining a reservoir (2) for conditioning a fluid product, and a pump mounted on the body to communicate with the reservoir via a product supplying device. The pump has bellows made of elastically deformable material and a lower part (40) arranged in the reservoir to communicate with the product. A purging membrane (34) is integrated in an outer wall of the lower part, and evacuates air and excess product in a dead space (35) during mounting the pump in the body. The membrane creates sealing between interior of the reservoir and the dead space after mounting the pump.
