Abstract

PURPOSE: To prevent the evaporation of a solvent from the surface of a liquid in an ink pan or the like and rise in the ink viscosity by covering the surface thereof without voidness with a normally polygonal float floating on the surface thereof.
CONSTITUTION: Floats are shaped spherical, semispherical, elliptically spherical, conical and in a regular polygonal form combining these shapes and cut off in a regular polygon on the circumference. Available shapes are also a regular polygonal cone and a regular polygonal prism including triangular pyramid, regular tetrahedron and triangular prism and the combination thereof. The specific gravity of the float ranges from 0.1 to 0.8. When printing, these floats are thrown into an ink pan 2 in a proper amount. They covers the surface of the liquid completely cutting the outside air and the evaporation of a solvent can be prevented thereby improving the working environment and checking rise in the ink viscosity.
