SEAMLESS CAPSULE AND PROCESS FOR PRODUCING THE SAME

摘要

A seamless capsule comprises a content and a film for coating the content. The content is a hydrophilic substance. A viscous liquid having a viscosity of no more than 1000 cp at 100.degree.C that is scarcely miscible with water is present between the content and the film. A process for producing this capsule comprises simultaneously extruding a film solution for the capsule, a hydrophilic substance solution and the viscous liquid that is scarcely miscible with water into a cooling solution from a concentrically arranged multiple nozzle assembly composed of at least three nozzles, an outermost nozzle, an innermost nozzle and at least one intermediate nozzle between the inner and outer nozzles, the diameter of the nozzles gradually increasing in that order.
