Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は密封容器の蓋の製造方法である。[Detailed description of the invention] [Industrial application field] The present invention is a method for manufacturing a lid for a sealed container.
一般に、容器本体と接する蓋のシール部は、容器本体の
素材の硬さに対応してより軟らかい素材により構成され
、これにより容器本体と蓋のシール部との密着性を良く
する方法がとられている。Generally, the sealing part of the lid that comes into contact with the container body is made of a softer material that corresponds to the hardness of the material of the container body, thereby improving the adhesion between the container body and the sealing part of the lid. ing.
その方法として蓋全体を軟らかい素材で作るが或は蓋本
体を硬い材質で構成し容器本体とのシール部に軟らかい
素材のパフキング材を用いる方法が行なわれている。As a method for this purpose, the entire lid is made of a soft material, or the lid body is made of a hard material, and the sealing portion with the container body is made of a soft puffing material.
蓋本体とシール部とが品質が異なる場合には、従来は蓋
本体とシール部とを別々に成形し、シール部を蓋本体に
接着或は嵌合して使用している。When the quality of the lid body and the seal portion are different, conventionally the lid body and the seal portion are molded separately, and the seal portion is used by adhering or fitting to the lid body.
この場合、蓋の組立工程が必要となる０本発明は、組立
工程を省略したものである。In this case, the present invention, which requires a lid assembly process, omits the assembly process.

造方法である。The present invention provides a method for manufacturing a lid having a lid body (1) and a sealing part (2) made of a material softer than the lid body (1), in which either the lid body (1) or the sealing part (2) is The lid body (1) or the seal part (2) is injection molded in a mold, and the other one is molded without completely releasing the molded lid body (1) or the seal part (2) from the mold. is the seal part (
2) This is a method for producing a lid, which is characterized by injection molding in close contact with the lid.
本発明を具体的に図面により説明する。The present invention will be specifically explained with reference to the drawings.
第１図は、本発明の方法により製造された蓋であり、蓋

ル部（２）に押圧して密閉した状態を示している。Figure 2 shows an example of the use of the lid manufactured by the method of the present invention, in which a spiral ridge (6
) and the spiral crest (3) of the lid are engaged, and the opening (5) is pressed against the sealing part (2) to seal the lid.
第３図はシール部（２）を成形する状態を示している。FIG. 3 shows the state in which the seal portion (2) is molded.
図中、雄型（７）は雌型（９）と、シール部（２）の空
間をあけて嵌合しており、樹脂はシール部（２）の空間
に通じて雌型（９）に設けられた注入口（８）からシー
ル部（２）の空間に注入される。In the figure, the male mold (7) is fitted to the female mold (9) with a space in the seal part (2), and the resin passes through the space in the seal part (2) and into the female mold (9). It is injected into the space of the seal part (2) from the provided injection port (8).

用できるので便利である。After molding the seal part (2) - the female mold (9) for fire forming is removed from the male mold (7), and the female mold (11) for secondary molding is removed with a space left in the lid body (1). It is fitted into the male die (7) with the seal part (2) still attached. The resin is injected through the injection port (1o) provided in the female mold (11) and then injection molded. The completed lid is convenient because the lid body (1) and the seal portion (2) are almost fused and inseparable, and can be used as is.
本発明の蓋は種々の素材を選択して使用することができ

、これにより、蓋を組立工程を射出成形の段階で吸収す
る利点がある。Various materials can be selected and used for the lid of the present invention, and for example, high-density or low-density polyethylene, polypropylene, urethane, etc. can be used in combination. Moreover, various multi-material injection molding machines can be used as the molding machine, which has the advantage of absorbing the assembly process of the lid at the injection molding stage.
