Abstract
A pump for dispensing foam that includes a pump head having a mixing chamber and a porous member. The pump head includes a tube and diaphragm. The pump includes a cap having a body defining a cavity that receives the tube. The cap is connected to the diaphragm to define an air chamber communicating with the mixing chamber. The pump includes a spring system received in the tube and cavity. The tube, cavity, and spring system define a liquid chamber that communicates with the mixing chamber. The spring system includes a spring positioned to be compressed such that liquid is urged from the liquid chamber to the mixing chamber and the diaphragm is configured to be compressed such that air is drawn from the air chamber to the mixing chamber. The liquid and air commingle into a mixture that is pushed through the porous member to form a foam. A container having a mechanism that delivers liquid from a container to a mouth and that moves between an extended position and a depressed position to deliver the contents of the container to the mouth and a removable securing cap that retains the mechanism in the depressed position.
