Abstract

An apparatus for dispensing material includes: a chamber for the material, the chamber sealed by a flexible seal; a nozzle coupled to the chamber and residing at a front end; and a pump, the pump comprising: a piston that moves in a tube, and an activator. When a user presses the activator, the piston moves toward or away from the front end, and a portion of the material is emitted onto the user's palm or fingers. The pump emits the portion of the material regardless of a direction of gravitational pull. In one embodiment, the piston emits the material by directly contacting the material in the chamber. In another embodiment, air is allowed into the chamber through a weep hole, which resides between the piston and the material. The air is used to expel the material through the one-way valve.
