Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
165 words
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.
Claim 2
Dependent Claim
165 words
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.
Claim 3
Dependent Claim
75 words
A dispensing device as recited in claim 1, wherein said compression means also includes: a slidable frame; a carriage formed to slidably receive said frame thereon; a spool rotatably supported in said frame; a cable wound around said spool having a hook means secured to the free end thereof for removable attachment to one of said walls; a crank means for rotating said spool; and a biasing means positioned between said frame and said carriage.
Claim 4
Dependent Claim
27 words
A dispensing device as recited in claim 2, wherein said housing includes as receptacle to support said container means therein, said receptacle having a hole disposed therein.
Claim 5
Dependent Claim
60 words
A dispensing device as recited in claim 3, wherein said container means comprises: a flexible, plastic bag formed as a continuous sealed envelope having said viscous materials stored therein; a nipple outlet mounted to said bag to receive said discharge tube thereon; and retainer means formed as part of said bag and said housing, whereby said bag is held therein.
Claim 6
Dependent Claim
55 words
A dispensing device as recited in claim 4, wherein said device includes: a gun handle having a main body with a cavity disposed therein and a removable cover; and a trigger means operably supported in said main body and wherein said control valve means is disposed within said cavity and operated by said trigger means.
Claim 7
Dependent Claim
74 words
A dispensing device as recited in claim 5, wherein said retainer means comprises: a longitudinal lip member formed along one end of said bag opposite that of said nipple outlet; an elongated channel formed along the lower edge of one wall; and an elongated rib member formed in said other wall and arranged to be received in said channel of said opposite wall thereof, wherein said longitudinal lip of said bag is locked therebetween.
Claim 8
Dependent Claim
30 words
A dispensing device as recited in claim 5, wherein said gun handle includes a latching means whereby said cover can be removably latched to said main body of said handle.
Claim 9
Dependent Claim
53 words
A dispensing device as recited in claim 5, wherein said control valve comprises: a valve arm positioned in said handle for direct engagement with said discharge tube; a leg member attached to said arm for operable engagement with said trigger means; and a biasing means integrally formed as part of said valve arm.
