PROBLEM TO BE SOLVED: To provide a device for extruding a highly viscous substance which is capable of efficiently completely extruding highly viscous material in a container body, reducing a waste in material cost, facilitating the cleaning work. SOLUTION: A container body 2 comprises a conical bottom surface 3 and a cylindrical side wall 4 in a recessed section, and a discharge hole having a control valve 5 is formed in the center of the conical bottom surface 3. A pressing plate 1 is slidably fitted in the cylindrical side wall 4 of the container body 2, and a bottom surface 1a is formed to have a truncated conical shape substantially equal to the conical bottom surface 3 of the container body 2. A rubber-like elastic body 7 formed of a sponge plate or a rubber plate is integratedly fitted to the bottom surface 1a of the pressing plate 1 along the shape of the bottom surface. |
