本発明は、上記のような蓋板付き容器を高気密の容器として、該容器内へ収納させた収納物が、該容器内へ入った空気により酸化等することが少なく、永く新鮮な状態を保つことが可能に形成したものである。   The present invention uses a container with a cover plate as described above as a highly airtight container, so that the contents stored in the container are less likely to be oxidized by the air that has entered the container, and the state is long and fresh. It is formed so that it can be kept.

第１の手段として、
容器体口頸部へ嵌合させたキャップ本体頂壁13に設けた開口15を蓋板21で閉塞させた蓋板付き容器において、
上記容器体口頸部上方のキャップ本体頂壁13部分の下面と口部内周面とを、該キャップ本体と共にインサート成形した弾性材30で覆合させ、
上記キャップ本体頂壁13下面を覆って口頸部上端面に接する弾性材部分をパッキン33とすることでこのパッキン33をキャップ本体頂壁13下面と口頸部上端面との間に挟持させると共に、
上記蓋板21からシール用筒25を垂下させて、蓋板開閉の際、該シール用筒25が、頂壁13内周面を覆う弾性材部分が形成する筒孔26内面へ、気密に着脱可能に形成することで、上記頂壁13内周面を覆う弾性材部分をその上記頂壁内周面とシール用筒25との間に挟持させ、
上記キャップ本体頂壁13の内周面から、複数の保持突起29を、相互に間隔を存して頂壁中心方向へ突出させ、これ等各保持突起29を、頂壁13内周面を覆う弾性材部分へ埋設させた。 As a first means,
In the container with a lid plate in which the opening 15 provided in the top wall 13 of the cap body fitted to the container body neck is closed with the lid plate 21.
The lower surface of the cap body top wall 13 part above the mouth and neck of the container body and the inner peripheral surface of the mouth are covered with an elastic material 30 insert-molded together with the cap body,
An elastic material portion that covers the lower surface of the top wall 13 of the cap body and is in contact with the upper end surface of the neck portion is used as a packing 33 so that the packing 33 is sandwiched between the lower surface of the top surface 13 of the cap body and the upper end surface of the neck portion. ,
When the sealing cylinder 25 is suspended from the lid plate 21 and the lid plate is opened and closed, the sealing cylinder 25 is attached and detached in an airtight manner to the inner surface of the cylindrical hole 26 formed by the elastic material portion covering the inner peripheral surface of the top wall 13 . By forming it possible, the elastic material portion covering the inner peripheral surface of the top wall 13 is sandwiched between the inner peripheral surface of the top wall and the sealing cylinder 25 ,
A plurality of holding projections 29 protrude from the inner peripheral surface of the cap main body top wall 13 toward the center of the top wall with a space therebetween, and these holding projections 29 cover the inner peripheral surface of the top wall 13. Embedded in the elastic material part .

第２の手段として、上記第１の手段を有すると共に、上記頂壁13内周面を覆う弾性材部分が形成する筒孔26内へのシール用筒25嵌合時に弾性圧縮されるシール突条31を周設した。 As a second means, the seal protrusion having the first means and elastically compressed when the sealing cylinder 25 is fitted into the cylindrical hole 26 formed by the elastic material portion covering the inner peripheral surface of the top wall 13 is provided. 31 was placed around.

第３の手段として、上記第１、又は第２の手段を有すると共に上記蓋板21をキャップ本体周壁14の後部にヒンジ連結した。 As a third means, the first or second means is provided, and the lid plate 21 is hinged to the rear portion of the cap body peripheral wall 14.

請求項１記載のようにすることで、キャップ本体12と、該キャップ本体の頂壁下面と頂壁内周面とを覆う弾性材30とは、共にインサート成形するから、そのキャップ本体から弾性材30が剥離等することがなく、頂壁下面を覆う弾性材部分がパッキン33を形成するから、該パッキンを別成形した場合のような、パッキン装着の手間を不要とでき、又キャップ本体着脱時にそのパッキンが外れて落ちるおそれもない。更に蓋板によるキャップ本体口部の閉塞は、キャップ本体頂壁開口15の内周面を覆合する弾性材部分内面が形成する筒孔26内へ、蓋板から垂下させたシール用筒25を嵌合させて行うよう設けたから、そのシールは上記弾性材部分が形成する筒孔26の内面とシール用筒25の外面とで上下方向において行われることとなり、よってキャップ本体に対する蓋板21押下げによる閉蓋が多少不完全であっても上記筒孔内面からシール用筒25が抜出さない限り開孔することがなく、そのシールを確実とすることが出来る。   Since the cap main body 12 and the elastic material 30 covering the top wall lower surface and the top wall inner peripheral surface of the cap main body are both insert-molded, the elastic material is removed from the cap main body. 30 does not peel off, and the elastic material part covering the lower surface of the top wall forms the packing 33, which eliminates the need for packing as in the case of separate molding of the packing, and when the cap body is attached / detached. There is no risk of the packing coming off and falling. Further, the closure of the cap main body opening by the lid plate causes the sealing cylinder 25 suspended from the lid plate into the cylindrical hole 26 formed by the inner surface of the elastic material part covering the inner peripheral surface of the cap body top wall opening 15. Since it is provided so as to be fitted, the sealing is performed in the vertical direction between the inner surface of the cylindrical hole 26 formed by the elastic material portion and the outer surface of the sealing cylinder 25, and therefore the lid plate 21 is pressed down against the cap body. Even if the lid is somewhat incomplete, as long as the sealing cylinder 25 is not pulled out from the inner surface of the cylindrical hole, the sealing hole is not opened, and the sealing can be ensured.

また請求項１のようにすることで、キャップ本体周壁から内向きフランジ状に突出する頂壁13の内周面を覆う弾性材部分の肉厚を厚くしてもその覆合部分が柔軟となり過ぎることはなく、適度の剛性を有してシール用筒25の着脱が容易な構成とすることが出来る。 Moreover, even if it thickens the thickness of the elastic material part which covers the inner peripheral surface of the top wall 13 which protrudes in an inward flange shape from a cap main body peripheral wall by making it like Claim 1, the covering part becomes too flexible. In other words, the sealing cylinder 25 can be easily attached and detached with appropriate rigidity.

請求項２のようにすることで、頂壁内周面を覆合する弾性材部分が形成する筒孔26内へのシール用筒嵌合時における気密性を高めることが容易となる。 By making it like Claim 2 , it becomes easy to improve the airtightness at the time of the cylinder fitting for a seal | sticker in the cylinder hole 26 which the elastic material part which covers a top wall inner peripheral surface forms.

請求項３のようにすることで、閉蓋時、蓋板のシール用筒下端は、ヒンジを中心とする回動で上記弾性材部分が形成する筒孔26内へ確実に嵌合することとなり、その嵌合が容易である。 According to the third aspect , when the lid is closed, the lower end of the sealing cylinder of the lid plate is securely fitted into the cylindrical hole 26 formed by the elastic material portion by turning around the hinge. The fitting is easy.
