Abstract (en)
[origin: WO2015007671A1] The invention relates to a device (1) for withdrawing and dispensing a viscous product (3) without taking in air, said device on the one hand comprising a pumping member (3) positioned, by its base (8), at the open end (4) of a rigid container (5) associated with a retractable flexible inner pouch (6), intended to receive the product (2), and on the other hand a plunger tube (7) connected by its upper end (7a) to a corresponding part (3a) of the pumping member, such that the upper end (7a) is partially submerged in the product (2) and the free lower end (7b) is completely submerged in the product (2), characterized in that the plunger tube (7) is made up of: - a first upper part (7A), with a closed circumference, defining a reference section (S1) of the tube (7), - a second lower part (7B) submerging the first (7A), with a circumference open by at least one longitudinal slot (9), made along a generatrix and defining a C- or U-shaped section on that part of the tube (7).
