Description
基端が開口し、基端から先端に向かって縮径するテーパー状の嵌合部と、前記嵌合部の先端外周壁に形成された凹部とを含むキャップである。このように、嵌合部の先端外周壁に凹部を設けることによって、嵌合部先端の内径が大きくなり、シリンジ先端の外径と嵌合部先端の内径との大きさの差が小さくなる。その結果、キャップの変形は小さくなるのでキャップのフレキシブルさが増し、キャップの復元力を適度に働く状態とすることができるため、キックバック現象を緩和することが可能である。また、復元力が適度に働くことによって、キャップのシリンジ先端からの緩みもなく、反対にしっかりと嵌合するため、シリンジ内から液が漏洩することもない。
