Foam dispensing pump with compressible air inlet chamber for residual suction |
| abstract |
The present application discloses exemplary dispensers, pumps and refill units. An exemplary refill unit includes a container and a foam pump. The foam pump includes a liquid pump chamber, a compressible air inlet chamber, and a compressed air inlet. The volume of the compressible air inlet chamber is less than the volume of air used to generate a dose of foam. A one-way air inlet valve is positioned adjacent to the compressed air inlet. A piston is also included and is movable within the liquid pump chamber and has a liquid sealing member and an air sealing member. The liquid pump chamber includes a liquid outlet opening into the central portion of the piston. One or more openings extend through the piston wall and provide passage from the compressible air chamber to the central portion of the piston. The pump also includes mixing media and an outlet. |
