A pump for discharging bubbles is provided on a neck portion of a container body. The pump for discharging bubbles comprises a cylinder for liquid in which a first piston slides, a cylinder for air in which a second piston slides, a pump head on which a nozzle is provided and which is connected to the first piston and the second piston so as to drive the both pistons, a vapor-liquid mixing chamber in which liquid delivered from the cylinder for liquid and air delivered from the cylinder for air are joined and a bubbling member provided between the nozzle and the vapor-liquid mixing chamber. Liquid within the container body and outside air are pumped up to be joined in the vapor-liquid mixing chamber and the vapor-liquid is bubbled via the bubbling member to be discharged in a foamy state from the nozzle by depressing the pump head.

Une pompe d'injection (10) de bulles est installée dans la portion de col (2) d'un corps d'un récipient (1). La pompe d'injection (10) de bulles comprend un cylindre (24) à liquide dans lequel coulisse un premier piston (50), un cylindre (22) contenant de l'air dans lequel coulisse un second piston (60), une tête de pompe (100) pourvue d'un orifice d'injection (113), reliée aux premier et second pistons (50, 60) et les entraînant, une chambre de mélange (46) gaz-liquide, dans laquelle un liquide est envoyé depuis le cylindre (24) à liquide et de l'air est envoyé depuis le cylindre (22) à air pour effectuer leur mélange, et un élément générateur de bulles (130) disposé entre l'orifice d'injection (113) et la chambre de mélange gaz-liquide (46). On pompe le liquide à l'intérieur du récipient et l'atmosphère externe au récipient en appuyant sur la tête (100) de pompe et ils sont mélangés dans la chambre de mélange gaz-liquide (46). Le mélange est transformé en mousse par l'élément générateur de bulles (130) et il est éjecté par l'orifice d'injection (113) sous la forme de bulles.
