Patent number: 5421469Abstract: The present invention relates to a synthetic resin sealing cap for a fluid bottle, comprising an annular cover, a ring-like clamping member, a synthetic resin cap, and a sealing member. In the present invention, just pulling the cover up makes a separation of the cover and the sealing member fixed each other from the synthetic resin sealing cap, thereby conveniently injecting a syringe's needle into the exposed rubber stopper for use of the fluid inside the bottle. And also, the upper surface of the rubber stopper is not contaminated by fragments of aluminium and a surface coating agent since an aluminium cap is not used.Type: GrantFiled: February 22, 1994Date of Patent: June 6, 1995Assignees: Morihiro Sudo, Yong-Hak LeeInventor: Yong-Hak Lee

Patent number: 5335801Abstract: A stopper sealing for an injectable fluid bottle suitable for protection of an upper surface of a rubber stopper of the bottle from contamination. The sealing cap comprises a sealing member for sealing the upper surface of the rubber stopper to prevent contaminant infiltration onto the upper surface of the stopper, an aluminum cap member engaging with the sealing member and covering the uppermost part of the bottle, and a synthetic resin cap member covering the aluminum cap member and engaging with the sealing member. The aluminum cap member has a center opening for receiving the sealing member and remains on the upper section of the bottle when the sealing member is removed from the bottle. The resin cap member is removed together with the sealing member from the bottle and has a center opening for receiving the sealing member, and a plurality of vertical slots; on its side inner surface for providing spaces between it and the aluminum cap member.Type: GrantFiled: August 3, 1993Date of Patent: August 9, 1994Inventor: Yong-Hak Lee
