とするものである。[Detailed description of the invention] This invention relates to a container cap in which a synthetic resin interior is integrally molded inside a metal outer lid 1 by insert molding. In addition to forming the protrusion 2, an inner cover 3 made of synthetic resin is integrally molded inside the metal outer cover 1 by insert molding, and the protrusion 2 is embedded in the wall of the inner cover 3. That is.

されている。The details of the present invention will be described below with reference to an embodiment shown in the drawings. 1 is a metal outer cover made of aluminum or the like; 2 is a plurality of protrusions formed on the inner peripheral wall surface of the outer cover 1 by thermal spraying; 3
1 is an inner cover made of synthetic resin that is integrally molded inside an outer cover 1 by insert molding, and the protrusion 2 is embedded in the wall portion of the inner cover.

着剤の老化並びに合成樹脂の収縮により内蓋のガタブレ
或いは抜出し等の欠点があった。Conventionally, this type of cap, which is mainly used for cosmetic containers, etc., has a metal outer lid and a synthetic resin inner lid that are molded separately, and the two are fitted and fixed with adhesive. Due to aging and shrinkage of the synthetic resin, there were drawbacks such as the inner lid wobbling or falling out.

廉価に製造し得る利点を有するものである。In this case, a plurality of protrusions 2 are formed by thermal spraying on the inner circumferential wall surface of a metal outer cover 1 as shown in the diagonal above, and an inner cover 3 made of synthetic resin is integrally molded inside the metal outer cover 1 by insert molding. However, the protrusion 2 is embedded in the wall of the inner cover 3, so that even if the inner cover 3 becomes slightly loosened due to contraction of the synthetic resin, it is firmly fixed by the protrusion 2.
There is no risk of the inner cover 3 wobbling or coming out, and internal slippage of the inner cover 3 can be completely prevented, and since the inner cover 3 is integrally molded into the outer cover 1 by insert molding, manufacturing time is reduced. This has the advantage of not only being able to save time, but also being suitable for mass production and making it possible to manufacture robust products at low cost.
