Abstract
A dispensing container for dispensing a desired quantity of a highly viscous material. The dispenser includes a generally tubular housing having an upper edge, an inner surface, a top secured to the upper end of the housing with at least one restricted dispensing opening, and a platform with a peripheral edge mounted for reciprocal axial movement within the housing. The peripheral edge of the platform is slidingly guided by the inner surface of the housing and supports the platform at a desired position within the housing. Further, the platform is slidably advanced towards the dispensing opening in the top by exertion of force by a user, where the force compresses the material against the top. Upon release of the force, the platform slidably moves in a reverse direction to relieve the stress in the material.
