PROBLEM TO BE SOLVED: To provide a medical cap in which a plug body is made of a thermoplastic elastomer and performance of such as re-sealing performance of needling is more improved.SOLUTION: The medical cap includes a plug body 10 made of a thermoplastic elastomer resin and an outer frame body 20 made of a synthetic resin. A side face part of the plug body 10 is held in a state being in contact with an inner wall 211 of a side periphery part of the outer frame body 20 and receiving pressure from an outer frame leg part 22. As a result, a liquid contact face of the plug body 10 is brought into a state not being a plane but having a downward convex slant in the circle center direction. A projection part 14 can be set on the liquid contact face, in this case, the bottom face of the projection part 14 being a part of the liquid contact face is to have the downward convex slant in the circle center direction.COPYRIGHT: (C)2010,JPO&INPIT【課題】栓体が熱可塑性エラストマー材料である、針差しの再シール性等の性能がより一層改善された医療用キャップを提供する。【解決手段】熱可塑性エラストマー樹脂の栓体10と、合成樹脂の外枠体20とからなる医療用キャップにおいて、栓体の側面部が、外枠体の側周部の内壁211と非融着状態で接触しており、かつ外枠体脚部22から圧力を受けた状態で保持されている。その結果、栓体の接液面は、平面ではなく、円中心方向へ下方に凸の傾斜を有することになる。接液面に突出部14を設けることもでき、この場合、接液面の一部である突出部の底面が円中心方向へ下方に凸の傾斜を有することになる。【選択図】図１
