Abstract
A dispenser has a main hollow housing with side walls, a base and an open top which is at least partially open for dispensing material. A vertical support column is slidably mounted within the housing with horizontal ratchets and a push plate on top. A trigger component within the main hollow housing is movably connected to the housing and to the horizontal ratchets, and has an advancer arm, an opposing retractor arm and a flexible spring. The trigger component acts as a trigger, a ratcheting member and a spring and is strategically positioned in a swingable manner such that it may be rotated inwardly and released outwardly to cause advancement or retraction of the vertical support column.
