ABSTRACT:
The present invention involves a dispenser. The dispenser includes a main hollow housing with side walls, a base and an open top which contains a manifold component for dispensing material therethrough. At least one vertical support column is included within the hollow housing and it has horizontal ratchets thereon as well as a push plate located at its top. A trigger component is also contained within the housing and it is formed of plastic material with at least one flexible portion therein. It acts as a trigger, a ratcheting member and a spring, and is strategically positioned in a hinged manner such that a side wall cut-out or other member holding the trigger component against the vertical support column ratchets may be rotated inwardly and released outwardly to cause the ratcheting mechanism to advance the support column. Thus, the trigger component has a first position and a second position wherein, when it is moved from the first position to the second position, it advances the vertical support column upwardly and when it is released and moves from its second position back to its first position, it retreats to the next lower ratchet on the support column and is set for the next advance. In one preferred embodiment, the main hollow housing has two separate components for ease of manufacturing and assembling.
