Patent number: 9962498Abstract: An object is to provide a syringe that is capable of preventing a cap from being mounted to a syringe body at an oblique angle. The cap includes an elastic cylindrical body for receiving an injection needle therein and sealing a holding part, and an external cylindrical body for covering the circumference of the elastic cylindrical body and holding the elastic cylindrical body in such a manner as to prevent movement of the elastic cylindrical body. The external cylindrical body includes an opening part having a dimension configured to be larger than the holding part of the syringe body, and a guide part that guides the injection needle toward a certain direction by coming into contact with a part of the syringe body when the injection needle is received inside the elastic cylindrical body.Type: GrantFiled: October 24, 2013Date of Patent: May 8, 2018Assignee: Taisei Kako Co., Ltd.Inventors: Taiji Horita, Ippei Matsumoto, Kensuke Taniguchi

Patent number: 9039664Abstract: In a prefilled syringe including an elastic seal member to be pierced with a needle for use to eject a protein pharmaceutical preparation therefrom, the elastic seal member ensures smooth and reliable piercing thereof with the needle while reliably preventing an active substance of the protein pharmaceutical preparation from being adsorbed thereon. When a protective film (3) is laminated to a top surface of a seal body (2) of an elastic material, the protective film (3) is stretched to a greater extent by a recess (4) provided in the top surface. Further, the piercing portion to be pierced with the needle is provided in a bottom of the recess (4). Thus, the protective film (3) is formed as locally having a smaller thickness in the piercing portion.Type: GrantFiled: April 16, 2012Date of Patent: May 26, 2015Assignee: Taisei Kako Co., Ltd.Inventors: Yukihiro Ogawa, Yasuyuki Shiraishi, Taiji Horita, Ichiro Suzuki
