ABSTRACT:
A viscous liquid dispenser which is used in a preferred embodiment for dispensing a viscous liquid such as drywall joint compound or "mud", wall plaster compositions and floor leveling compounds used in the construction industry. In a preferred design, the dispenser is characterized by a box-like container fitted with a lever-operated plunger plate, which is sized to slidably extend into the container and force the viscous liquid compound through a nozzle located in one of the container walls by hand operation of the lever. In another preferred embodiment of the invention, the nozzle is fitted with a removable cutter blade which is exposed to the interior of the container for cutting an encapsulating plastic bag which contains the viscous liquid after the plastic bag and liquid are placed in the dispenser container and pressure is applied to the plastic bag by operation of the plunger plate and lever. In yet another preferred embodiment, optimum pressure is applied by means of a lever having one end hinged to the container dispenser and adjustably fitted with a slotted connector bar which pivotally connects the lever to the plunger plate.
