The first hook 13 that is raised and the second hook 14 that is suspended from the front part of the cover plate are engaged by the cover plate lying down and the cover plate is closed, and the lever type push button 15 is pushed down. The push button rear part pushes up the front part of the cover plate and the hooks are disengaged to open the cover, and when the cover plate front part is pushed down from the open state, the hooks are engaged again to close the cover state. It is provided to keep.

本発明では、既述第1シール筒8へ気密に嵌合させる弾性第2シール筒21を蓋板11下面へ直接ないし間接に付設させた。該弾性第2シール筒21は、図1が示す第1実施形態にあっては、リング状板22外周から第1短筒23を垂下し、該第1短筒下端に付設した外向きフランジ24を介して上外方へ筒部を拡開する、例えばエラストマーで形成した弾性部材25を設け、上記外向きフランジ24外周から上外方へ起立する筒部で形成した。該弾性部材25のリング状板22は剛性の合成樹脂製円板26の外周部上面へ載置した状態でインサート成形して第1シール部材27を形成し、上記リング状板22よりも内方の円板部分から起立させた第2係止筒28を、蓋板11の中央部下面から垂設した第1係止筒29内面へ嵌着して固定し、又蓋板11から第3短筒30を垂下させて該第3短筒30を上記第2短筒23外面へ嵌合させ、上記弾性第2シール筒21外面を、第1シール筒8内面へ気密に嵌合させている。   In the present invention, the elastic second seal cylinder 21 that is airtightly fitted to the first seal cylinder 8 is directly or indirectly attached to the lower surface of the lid plate 11. In the first embodiment shown in FIG. 1, the elastic second seal cylinder 21 hangs down from the outer periphery of the ring-shaped plate 22 and the outward flange 24 attached to the lower end of the first short cylinder. An elastic member 25 made of, for example, an elastomer is provided so as to expand the cylinder part upward and outward through the pipe, and the cylinder part is formed to rise upward and outward from the outer periphery of the outward flange 24. The ring-shaped plate 22 of the elastic member 25 is insert-molded in a state of being placed on the upper surface of the outer periphery of the rigid synthetic resin disk 26 to form a first seal member 27, which is inward of the ring-shaped plate 22. The second locking cylinder 28 erected from the disc part of the first plate is fitted and fixed to the inner surface of the first locking cylinder 29 suspended from the lower surface of the central portion of the lid plate 11. The cylinder 30 is suspended to fit the third short cylinder 30 to the outer surface of the second short cylinder 23, and the outer surface of the elastic second seal cylinder 21 is airtightly fitted to the inner surface of the first seal cylinder 8.

The elastic second seal cylinder 21 is moved so as to be fitted into the upper part of the first seal cylinder 8. At the time of the fitting, the elastic second seal cylinder 21 contacts the upper inner surface of the first seal cylinder 8 and is prevented from descending, so that the outer peripheral portion of the outward flange 24 is pushed upward. Since the lower surface of the short cylinder 30 is in contact with the upper surface of the outward flange 24 to prevent the outward flange 24 from rising, the elastic second seal cylinder 21 is pushed into the upper portion of the first seal cylinder 8.

又本発明にあっては、剛性の合成樹脂製リング41下面と内面とを弾性板42で覆ってパッキン部43とし、かつ内面覆合部分を上方延長して板バネ部44としたパッキン兼用バネ部材45を設け、該部材のパッキン部43を、図が示すようにキャップ本体周壁上部との間に間隙をおいて頂壁6から垂下させた第1短筒9とキャップ本体周壁5との間へ嵌合させ、又その挾持筒外面上方の頂壁部分に透孔47を穿設し、該透孔に通して上記板バネ部44を上方へ起立させた。該板バネ部は図示のように蓋板11閉蓋時に蓋板に押されて弾性変形し、該状態から押しボタン15を押下げてロックを外すと、板バネ部44が弾性復元して開蓋するよう設けたものである。上記弾性板42はエラストマーで形成し、該弾性板とリング41とはインサート成形して一体成形している。   In the present invention, the lower surface and the inner surface of the rigid synthetic resin ring 41 are covered with the elastic plate 42 to form the packing portion 43, and the inner surface covering portion is extended upward to form the leaf spring portion 44. A member 45 is provided between the first short cylinder 9 and the cap body peripheral wall 5 which is suspended from the top wall 6 with a gap between the member 43 and the upper part of the cap body peripheral wall as shown in the figure. Further, a through hole 47 was formed in the top wall portion above the outer surface of the holding cylinder, and the leaf spring portion 44 was raised upward through the through hole. The leaf spring portion is elastically deformed by being pushed by the lid plate when the lid plate 11 is closed as shown in the figure, and when the push button 15 is pushed down to release the lock, the leaf spring portion 44 is elastically restored and opened. It is provided to cover. The elastic plate 42 is formed of an elastomer, and the elastic plate and the ring 41 are integrally formed by insert molding.
