A foam pump, or squeeze foamer and dispensing device is a non-aerosol way of dispensing liquid materials.[1] The foam pump outputs the liquid in the form of foam and it is operated by squeezing. The parts of the foam pump, mostly made from polypropylene (PP), are similar to those of other pump devices. The foaming pump often comes with a protective cap.
