Abstract

PURPOSE: To obtain a slow-releasing capsule having simple structure, efficiently, by successively inserting a second tube and a liquid permeable thread into a first tube consisting of a semipermeable membrane, thereafter charging a physiologically active liquid substance, etc. into the second tube.
CONSTITUTION: A second tube 2 consisting of a liquid-impermeable membrane (e.g. polyvinyl chloride film) and a liquid-permeable thread 3 (e.g. fiber) are successively inserted into a first tube 1 consisting of a semipermeable membrane (e.g. cellophane film). Then, a substance arising osmotic pressure (e.g. NaCl) 4 is charged into the space between both tubes 1,2, and physiologically-active liquid substance 5 (e.g. fish-attracting agent, insecticide, etc.) into the second tube 2. Subsequently, both tubes and the thread are sealed and integrated together at a definite position, and then cut at said sealed part 8 to obtain the slow-releasing capsule. The effective component is slowly released through the thread 3.
