Abstract
A dispenser for applying non-solid, thixotropic, viscous materials -- as, for example, mastic, caulking compound, coatings, paints or heavy greases -- the dispenser being adapted to removably receive disposable, interchangeable, collapsible bag means which contains the material to be dispensed, and including a trigger-operated handle adapted to receive a flexible discharge tube therethrough. Various discharge tips or rollers can be interchangeably attached to the discharge tube. The dispenser also includes a manually operated, compressive means to dispense the needed material in required amounts.
Claims8
A dispensing device for viscous materials comprising:
- a housing having a pair of hinged walls;
- a container means wherein the viscous material is stored therein, said container being removably disposed in said housing;
- hinge means positioned along the lower portion of said walls for pressure engagement with said container means;
- a discharge tube operably connected at one end thereof to said container means, whereby said viscous material can flow therefrom;
- a compression means attached to each of said walls, imparting an inward compression force thereto;
- wherein said compression means includes a take-up mechanism, said compression means being hingedly attached to one wall of said housing, and said take-up mechanism being operably accuated by the compression means and removably attached to said opposite wall whereby the viscous material is continuously and automatically placed under discharge pressure;
- a control-valve means mounted to said discharge tube, whereby the flow of material is controlled from said container;
- and
- coupling means formed in the free end of said discharge tube.
