があつた。 However, in this method, the capsules are soaked in water before use, so the water-absorbent paper container absorbs water and expands, making it impossible to push the capsules into the holes. The fixing strength changes greatly depending on the water absorption time. Since the curing start time is determined at the same time as water absorption, materials that set or harden quickly cannot be used. There were other issues.
本発明者は、これらの課題を解決する目的で
