Abstract
A dispensing pump including a pump mechanism and a pump bead is provided. The dispensing pump head includes an upper portion and a lower portion. The lower portion has a structure for attaching the dispensing pump to the container. The upper portion and the lower portion each has: (1) an internal area combining to form an enclosed space for containing a second product, and (2) a respective peripheral wall. The pump mechanism also includes a dispensing channel for the first product that extends between the upper and the lower portion. There is an aperture in either peripheral walls or a space between the respective peripheral walls. Upon the actuation of the dispensing pump, the upper portion passes into the lower portion to force air from the enclosed space and the second product is emitted through one of the apertures in either peripheral walls or the space therebetween.
