PROBLEM TO BE SOLVED: To provide a medical cap that allows a transfusion needle to be inserted with smaller force while securing high sealability, and can prevent an elastic plug body from being displaced in inserting the transfusion needle.SOLUTION: A medical cap 1A includes an elastic plug body 40, an outer frame body 10, and a resin fixing part 50 for fixing the elastic plug body 40 to the outer frame body 10 by being secured to both the elastic plug body 40 and the outer frame body 10. The elastic plug body 40 includes a first principal surface 40a, a second principal surface 40b, and a peripheral surface 40c while the outer frame body 10 includes a top plate part 21 facing the first principal surface 40a, and a side wall part 22 facing the peripheral surface 40c. An annular protruding part 42 is provided on the second principal surface 40b. The fixing part 50 buries a space between the elastic plug body 40 and the side wall part 22, and is provided so as to cover an outer edge part of the second principal surface 40b. An inside end part located on the second principal surface 40b of the fixing part 50 is located outside the innermost part of the surface of the annular protruding part 42.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】密閉性を高く確保しつつ移注針の刺し込みがより小さい力にて行なえるとともに、移注針の刺し込みの際に弾性栓体が位置ずれしてしまうことが防止できる医療用キャップを提供する。【解決手段】医療用キャップ1Aは、弾性栓体40と、外枠体10と、弾性栓体40および外枠体10の双方に固着することで弾性栓体40を外枠体10に固定する樹脂製の固定部50とを備える。弾性栓体40は、第1主面40a、第2主面40bおよび周面40cを有し、外枠体10は、第1主面40aに対向する天板部21と、周面40cに対向する側壁部22とを有する。第2主面40bには、環状突部42が設けられる。固定部50は、弾性栓体40と側壁部22との間の空間を埋め込むとともに、第2主面40bの外縁部を覆うように設けられ、固定部50のうちの第2主面40b上に位置する内側端部は、環状突部42の表面の最も内側の部分よりも外側に位置する。【選択図】図3
