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.
Pump for a receptacle, in particular a bottle intended to contain a cosmetic product, said pump comprising a pumping chamber with a variable volume defined at least partly by a deformable membrane, the pump functioning by varying the volume of the chamber by elastic deformation of the membrane between an initial state in which the chamber has a maximum volume and a deformed state in which the volume of the chamber is minimum, the chamber being provided with an inlet orifice and an outlet orifice for the product, the pump comprising a means for deforming the membrane configured to exert a pressure on the membrane, the pump further comprising a guide rod passing through the membrane, the membrane sliding along the rod when it undergoes said deformation.
