上記従来の蓋体付きキャップは、キャップ本体周壁に設けた板バネ内方押圧で、該板バネ上部外面と該上部外面へ嵌合する蓋体周壁部分内面との係合が外れて蓋体の開蓋が可能となるが、その係合が外れても蓋体は当初の位置に停止したままであり、又上記板バネ押圧が不充分なために上記係合の外れが不充分な場合も同様であるため、上記係合離脱が不充分なままで開蓋しようとしたり、又係合は外れているに拘らず板バネの内方押込みを続けることがあった。 In the above conventional cap with a lid, the leaf spring inward pressing provided on the peripheral wall of the cap body disengages the upper outer surface of the leaf spring and the inner surface of the lid peripheral wall portion fitted to the upper outer surface. Although the lid can be opened, the lid remains stopped at the initial position even when the engagement is released, and the release of the engagement may be insufficient due to insufficient pressure on the leaf spring. For the same reason, there is a case where the lid spring is attempted to be opened while the disengagement is insufficient or the inward pushing of the leaf spring is continued despite the disengagement.

本発明は上記欠点を除去して板バネ押圧で蓋体がキャップ本体に対して上昇し、上記係合解除が終わったことを目視できるよう設けたものである。 The present invention is provided so that the above-mentioned disadvantages can be eliminated and the lid can be lifted with respect to the cap body by pressing the leaf spring so that the disengagement can be visually confirmed.
