Abstract

(57)【要約】 薄いパッキング用の蓋は、パッキング材料を主蓋に粘着するのにプレス加工と曲げ加工が必要である。この発明は、主蓋のパッキング部分の上下からパッキングのプラスティック材料を射出可能な二材射出成形方式加工により、曲げ加工又はプレスなしに製造可能なパッキングの蓋である。 (57) [Summary] Thin packing lids require pressing and bending to adhere the packing material to the main lid. The present invention is a packing lid that can be manufactured without bending or pressing by a two-material injection molding method capable of injecting a plastic material for packing from above and below a packing portion of a main lid.

より密閉性が高く、軟質の成形材料と硬質の成形材料を互いに密着することが可
能なため、成形により平滑で平坦な蓋が製造される密閉容器に関する。TECHNICAL FIELD The present invention relates to a lid for a plastic container. For more details,
The present invention relates to an airtight container which has a higher airtightness and is capable of closely adhering a soft molding material and a hard molding material to each other, and thus a smooth and flat lid is manufactured by molding.

The portion 10a to be coupled with the container 20 is manufactured by a two-material injection molding method with a soft material on the outer edge portion of the cap 10 to form the main body 11, and the coupling portion 10a has a soft viscosity and thus has a high hermeticity. Become.

点で、キャップの本体11と成形条件が異なるためである。However, this type of prior art has a problem in that the cover is peeled off, distortion occurs during cooling, and the lid is not manufactured to be smooth and flat. The reason is that the cap body 11
Is usually injection-molded to a thickness of 1 mm, and the coating portion is molded by a coating method to a thickness of 0.1 mm, which is because the molding conditions are different from the main body 11 of the cap.

材料で被膜加工され、被膜加工部13は粘度があるので密閉性が高くなる。Therefore, in order to prevent this distortion, as shown in FIG. 7, when the main body 11 is integrally formed with the joint portion 10a by a two-material injection molding method, the inside of the joint portion 10a is coated with a soft material. Since the film-processed portion 13 is processed and has a viscosity, the hermeticity is improved.

a is formed with the body 11 of the cap, the coating layer 1 is formed inside the connection site 10a,
The coating layer projects through the hole 3 towards the surface of the cap 10 and forms a projection.
This is a design for protecting the coating layer 1 from peeling.

【００１０】 穴３の寸法と位置は本体の表面の形状によって決定され、開口部４を穴３の代
用とすることも可能である。The size and position of the hole 3 is determined by the shape of the surface of the body, and the opening 4 can be used as a substitute for the hole 3.

【００１１】 また、キャップ10の頂部に向かって突出した突出部２の表面に製品の商標が印
刷される。商標は二材射出成形方法用専用の金型に印刷される。したがって、低
コストで様々な種類の製品を生産することができる。Further, the trademark of the product is printed on the surface of the protrusion 2 that protrudes toward the top of the cap 10. The trademark is printed on a dedicated mold for the two-material injection molding method. Therefore, various types of products can be produced at low cost.

【００１２】 また、突出部２がキャップの輪郭に沿って一体に形成される、又は一定の間隔
をおいて形成される時、様々な種類の製品の生産が可能である。Further, when the protrusions 2 are integrally formed along the contour of the cap or formed at regular intervals, various kinds of products can be produced.

【００１３】 キャップ10と容器20が結合される結合部位の内壁に穴を開けることにより、キ
ャップの頂部に開けられる穴３を通して突出部２が一体に形成される時、密閉性
が改善され、キャップが曲がるのを防止することができる。By forming a hole in the inner wall of the connection site where the cap 10 and the container 20 are combined, the tightness is improved when the protrusion 2 is integrally formed through the hole 3 formed at the top of the cap, and the cap is improved. Can be prevented from bending.

【００１４】 また、内壁は二材射出成形方法によって形成され、キャップと容器が形成され
る接続部位10aに外壁が形成された後、キャップの穴３を通して突出部２が形成
される。Further, the inner wall is formed by a two-material injection molding method, and after the outer wall is formed at the connecting portion 10a where the cap and the container are formed, the protrusion 2 is formed through the hole 3 of the cap.

【００１５】 したがって、接続部位10aが二材射出成形方法により柔軟な成形材料と一体に
形成され、その結果、容器の蓋が曲がるのを防止する。被膜層はキャップに開け

形成されるので、商標を突出部上に印刷することができ、容器のデザインも良く
なる。Therefore, the connection portion 10a is integrally formed with the flexible molding material by the two-material injection molding method, and as a result, the container lid is prevented from bending. Since the coating layer is integrally formed with the cap through the hole formed in the cap, the coating layer can be made strong. And since the protrusion is formed when the coating layer contacts the cap through the hole in the cap, the trademark can be printed on the protrusion and the container design is also improved.
