The lid main body 8 is integrally formed with the lid main body 8 within the inner peripheral surface of the lid top 9.
【０００８】 かかる構成による密封容器用の蓋５は、二色射出成形機によって貫通孔を有す るパッキン部６を一次成形した後、別製の突起部７をパッキン部６における貫通 孔内にインサートした後、これをインサート部材とする二次成形によって蓋本体 ８を射出成形したものである。In the lid 5 for the hermetically sealed container having the above-described configuration, after the packing portion 6 having the through hole is primarily molded by the two-color injection molding machine, the separately formed protrusion 7 is placed in the through hole of the packing portion 6. After insertion, the lid body 8 is injection-molded by secondary molding using this as an insert member.
【０００９】 この密封容器用の蓋５は、該密封容器用の蓋５を係合させる容器の開口部の内 周面に突起部７の外周面が嵌合するものであって、密封容器用の蓋５による密封 性能が極めて良好になる。The lid 5 for the hermetically sealed container is such that the outer peripheral surface of the protrusion 7 is fitted to the inner peripheral surface of the opening of the container with which the lid 5 for the hermetically sealed container is engaged. The sealing performance by the lid 5 becomes extremely good.
【００１０】 本考案の密封容器用の蓋は、上記の実施例品のように、突起部を構成する部材 を予め成形しておき、該部材をパッキン部における貫通孔内にインサートした後 、これをインサート部材とする射出成形によって蓋本体を成形する方法、あるい は貫通孔を有するパッキン部をインサート部材とし、突起部と蓋本体との一体成 形体を射出成形する方法等によって得られる。In the lid for the hermetically sealed container according to the present invention, as in the above-mentioned embodiment, the member forming the protrusion is formed in advance, and the member is inserted into the through hole in the packing portion. Can be obtained by a method of molding the lid main body by injection molding using the insert member as the insert member, or a method of injection molding an integral molded body of the protrusion and the lid main body using the packing portion having the through hole as the insert member.
【００１１】 また、蓋本体と、突起部と、貫通孔を有するパッキン部との組み合わせとして は、［表１］に示すような樹脂の組み合わせを利用することができる。Further, as a combination of the lid main body, the protruding portion, and the packing portion having the through hole, a combination of resins as shown in [Table 1] can be used.
