Abstract: A pump for a receptacle (10), in particular a bottle intended to contain a cosmetic product. The pump (1) has a pumping chamber (8) with a variable volume defined at least partly by a deformable membrane (3). The pump (1) functioning by varying the volume of the chamber (8) by elastic deformation of the membrane (3) between an initial state in which the chamber (8) has a maximum volume and a deformed state in which the volume of the chamber (8) is minimum. The chamber (8) being provided with an inlet orifice (22) and an outlet orifice for the product. The pump (1) has a means for deforming the membrane configured to exert a pressure on the membrane (3) and a guide rod (20) passing through the membrane (3). The membrane (3) slides along the rod (20) when it undergoes said deformation.

Abstract: Air purge device for an airless liquid product dispenser having a container equipped with means for sampling the product. The device has a bleed ring that has a deformable lip seal accommodated inside a protective part designed to be inserted into the container. The deformation of the lip when mounting the air purge device in the container causes the air to be purged from the container.

Abstract: Suction device for a liquid product present in a dispenser has a container 6 provided with means for sampling the product 7. The device is developed about a central axis X and has a centralised product suction channel 8 coaxial to the central axis X and having an inlet 14 and an outlet; and annular suction means connected to the inlet 14 of the centralised suction channel 8.

Abstract: The invention relates to a pouch (6) having a flexible casing delimiting a reservoir wherein a product to be dispensed is intended to be conditions, said pouch being provided with a tip (19) comprising a base that has an exterior wall whereon is fixed in a sealed manner a mouth (21), said tip having a duct extending between a lower opening and an upper opening, the tip (19) also having a well that extends between an interior opening and a lateral opening coming out into the exterior wall by being covered in a sealed manner by the mouth (20), the upper opening opening to the exterior of the pouch (6), said tip being provided with a cap (26) which is arranged in order to be able to be mounted in said upper opening by closing in a sealed manner the communication between the reservoir and the exterior while still leaving open the communication between the reservoir and the well.

Abstract: The invention relates to a unit for dispensing a product comprising a case (1) and a cassette (2) which has a zone for dispensing (7) the product conditioned in a reservoir of said cassette, said cassette intended to be arranged in a housing (3) formed in a body of said case by arranging said dispensing zone in an access window (8) which is formed in an upper wall (4) of said body, said unit comprising a reversible locking mechanism of the cassette (2) in the housing (3) which has a frame (27) mounted in horizontal translation in said housing by being maintained vertically, said frame and said cassette being provided with complementary means which are arranged to, in a first position of the frame (27), allow for the arranging of the cassette (2) in the housing (3) with the dispensing zone (7) in the window (8) and, in a second position of said frame, lock the position of said cassette in said housing.
