Method for filling e.g. cream into tank in cosmetic field, involves actuating vacuum source to move follower piston by suction in sliding motion barrel to suck fluid product within storage space from fluid product reservoir

摘要

The method involves placing a follower piston (2) in a sliding motion barrel such that a fluid product storage space (Es) exhibits a minimal volume, and a dead space (Em) exhibits a maximum volume. A lower opening (13) of the dead space is connected to a vacuum source (4) i.e. double-acting jack, and an upper opening (17) of the storage space is connected to a fluid product reservoir (5). The vacuum source is actuated to move the follower piston by suction in the sliding motion barrel to suck a fluid product within the storage space from the fluid product reservoir. An independent claim is also included for a device for filling a fluid product into a tank.
