The dual size feature makes the tool suitable for a range of container sizes, especially one gallon and one quart containers. The absence of a bottom surface connected to the blade members enhances the efficiency of the tool. By one or two simple hand rotations of the tool while the appropriate blade member is inside the container, virtually all of the adhesive material can be removed. The length of the blade members, their placement with respect to one another and the placement of an angulated rod connecting the blade members to the handle make use of the tool simple and effective. ## Claims ### Claim 1 A new and improved hand tool for removing the contents of and for scraping clean a cylindrical container for adhesive materials, said tool comprising: an elongated handle; a large blade member having a substantially semicylindrical curvature connected to one end of an angulated rod and extending generally longitudinally therefrom and from the elongated handle; a small blade member having a substantially semicylindrical curvature connected to a second end of said angulated rod and extending generally longitudinally therefrom and from the elongated handle; and an angulated rod whose opposite ends are attached to a back surface of each said blade member and which is attached to said elongated handle. ### Claim 2 (depends on 1) The tool of claim 1, wherein said small blade member is positioned at a 180 degree revolution interval from said large blade member. ### Claim 3 (depends on 1) The tool of claim 1, wherein the length of said large blade member is six and three quarters to six and thirteen sixteenths. ### Claim 4 (depends on 1) The tool of claim 1, wherein the length of said small blade member is approximately four and one quarter inches. ### Claim 5 (depends on 1) The tool of claim 1, wherein the blade members are constructed by bending a sheet of galvanized steel into a substantially semicylindrical curvature. ### Claim 6 (depends on 5) The tool of claim 5, wherein said galvanized steel is twenty gauge in thickness. ### Claim 7 (depends on 1) The tool of claim 1, wherein said elongated handle is made of wood. ### Claim 8 (depends on 1) The tool of claim 1, wherein said angulated rod is made of metal. ### Claim 9 (depends on 1) The tool of claim 1, wherein said angulated rod is welded to said blade members. ### Claim 10 A new and improved hand tool for removing the contents of and for scraping clean a cylindrical container for adhesive materials, said tool comprising: an elongated handle; a large blade member having a substantially semicylindrical curvature connected to one end of an angulated rod and extending generally longitudinally therefrom and from the elongated handle; a small blade member having a substantially semicylindrical curvature connected to a second end of said angulated rod and extending generally longitudinally therefrom and from the elongated handle; and an angulated rod whose opposite ends are attached to a back surface of each said blade member and which extends through the interior of said elongated handle. ### Claim 11 (depends on 10) The tool of claim 10, wherein said small blade member is positioned at a 180 degree revolution interval from said large blade member. ### Claim 12 (depends on 10) The tool of claim 10, wherein the length of said large blade member is six and three quarters to six and thirteen sixteenths. ### Claim 13 (depends on 10) The tool of claim 10, wherein the length of said small blade member is approximately four and one quarter inches. ### Claim 14 (depends on 10) The tool of claim 10, wherein the blade members are constructed by bending a sheet of galvanized steel into a substantially semicylindrical curvature. ### Claim 15 (depends on 14) The tool of claim 14, wherein said galvanized steel is twenty gauge in thickness. ### Claim 16 (depends on 10) The tool of claim 10, wherein said elongated handle is made of wood. ### Claim 17 (depends on 1) The tool of claim 1, wherein said angulated rod is made of metal. ### Claim 18 (depends on 1) The tool of claim 1, wherein said angulated rod is welded to said blade members.
