Patent Searching and Data


Title:
【発明の名称】薬剤セルロース・カプセルを製造する方法および装置
Document Type and Number:
Japanese Patent JP3299744
Kind Code:
B2
Abstract:
A method and apparatus for manufacturing pharmaceutical capsules use an aqueous solution of a thermogelling cellulose ether composition and use capsule body pins and capsule cap pins as molds. The method involves heating the pins, dipping the pins into the solution to cause the solution to gelatinize on the surface of the pins, removing the pins and drying the gelatinized solution on the surface of the pins to form capsule bodies and capsule caps. The capsule parts may have a thick wall and a stiffening ring and the capsule parts are removed by gripping. The invention solves the problem of cracking at the dip-line edge by breaking adhesion between the capsule part and the pin before removing the capsule part from the pin.
