ABSTRACT:

A body (5) encloses the bag (1) and the pump (3). An actuating button (9) for the pump provided with an outlet for the product to be distributed. A movable member (10) is interposed between the downstream end (3') of the pump (3) and the outlet in the button (9) for the product, this movable member (10) having a first conduit (13) which in a first position of the movable member (10) places the upstream end (3') of the pump (3) directly in communication with the outlet of the button (9), and at least one second conduit comprising a direct circuit and a branch (22, 24, 25). This second conduit is so arranged that, in a second position of the movable member (10), the direct circuit (22, 24) places the downstream end (3') of the pump (3) in communication with the outlet of the button (9) while the branch (25) places the downstream end (3') of the pump (3) in communication with the upstream end of the pump (3).
