Abstract

PURPOSE: To obtain an encased packing storable without the influence of the moisture in air, by injecting a liquid raw material of a rubberlike resin capable of swelling in water into a case for molding and casting consisting of a moisture-impermeable material, enclosing the case, and solidifying the liquid raw material.
CONSTITUTION: A liquid raw material of a rubberlike resin, e.g. hydrophilic ethylene-vinyl acetate copolymer, hydrophilic urethane resin, or its mixture with natural rubber, capable of swelling in water is injected into a case for molding and casting consisting of an impermeable material, e.g. Al, PVC, PE, or PP, having ecavities in the form of a packing, and the case is then enclosed to solidify the liquid raw material.
EFFECT: Good dimensional stability without requiring the labor of new packaging and deterioration in swelling ratio.
