弱くバリヤー性に乏しいという問題点がある。Among the above-mentioned fitting type sealing caps, those made of metal are excellent in barrier property and have an advantage that they are excellent in design in that appropriate printing can be performed on the top surface. Since the opening operation is performed by tearing a part of the cap, there is a problem that there is a risk of injury at the broken portion, and there is a problem that the lid cannot be opened again once it is opened. On the other hand, a synthetic resin product can be fitted and removed because it has elasticity to some extent, but there is a problem that the fitting force is weak and the barrier property is poor.

る。The metal member 2 has a thickness of 0.1 to 0.5, for example.
It is formed by crimping a circular aluminum plate of mm into a predetermined shape, and has an upwardly facing step portion 22 around the top surface 21 and a downwardly extending portion 23 from the tip of this step portion 22. ing. Depending on the contents, metals other than aluminum, such as iron, may be used. Further, since it is made of metal, appropriate printing can be performed on the top surface in advance.

る。The synthetic resin member 3 is a top surface 21 of the metal member 2.
Is integrally attached to the metal member 2 so as to cover a part of the step portion 22 and the extended portion 23 around the inside of the container from both inside and outside, and further, the outward protrusion 41a of the mouth portion 41 of the bottle container 4 is provided. It has a shape in which a protrusion 31 for fitting and locking is provided inside the lower end of the extending portion 23 of the metal member 2 and an opening projecting piece 32 is provided outside the lower end.

は、ポリエチレン等の軟質な樹脂を使用する。The synthetic resin member 3 is integrally attached to the metal member 2 by setting the metal member 2 in a mold and integrally molding the synthetic resin around the metal member 2 by insert molding. Here, as the material of the synthetic resin member 3, a soft resin such as polyethylene is used.

とがない。In the sealing cap 1 having the above-mentioned structure,
Since the extending portion 23 of the metal member 2 is made longer so as to extend below the position of the engaging protrusion 41 of the synthetic resin member 3,
In the manufacturing process, when the metal member 2 is continuously transported on the transport line, front and rear objects do not run over and overlap.

用できる。The sealing cap 1 is fitted and fixed to the mouth portion 41 of the bottle container 4 after filling the bottle container 4 with contents such as liquid. In this case, when the cap 1 is pushed in, the protrusion 31 of the synthetic resin member 3 rides over the outward protrusion 41a of the mouth portion 41 of the bottle container 4 and engages with it. At that time, the inner surface of the side wall of the cap 1 with which the bulge 41a abuts is pressed outward, but the extended portion 23 of the metal member 2 is present in the side wall portion of the cap 1 and the structure is high in rigidity. Therefore, the soft synthetic resin member 3 does not bend outward, and eventually the soft synthetic resin member 3 is compressed and deformed by the force from both inside and outside, and the bottle container 4 is hermetically sealed by the cap 1 in a state of being closely attached at the protruding portion 41a. Then, the outer side of the cap 1 is sealed by shrink wrapping to form a sales form. At the time of opening, after the shrink wrap is peeled off, the protrusion 32 of the synthetic resin member 3 is pushed up to release the engagement between the protrusion 31 and the protrusion 41a of the bottle container 4. Further, it can be used as a detachable cap after opening.

ものである。In the above embodiment, the upwardly facing step portion 22 is formed around the top surface 21 of the metal member 2.
The top surface 21 may have a flat shape as a whole or in a single direction. Further, as shown in FIG. 4, a downward step portion 23 may be formed around the top surface 21, and in this case, the synthetic resin member 3 is integrally molded by filling the step portion 23. The top surface of the cap 1 can be flattened as shown in FIG. In any case, the shape of the top surface 21 of the metal member 2 may be appropriately determined according to the design of the cap 1.

ビン容器を密閉することができるという効果も奏する。As described above, according to the present invention, the metal member having the downward extending portion on the outer peripheral edge of the top surface, and the periphery of the top surface and the extending portion are covered from both inside and outside. A soft synthetic resin member integrally attached to the metal member constitutes a closed cap, and the synthetic resin member further has a projection for engaging and locking with an outward protrusion of the mouth of the bottle container. Since it has a protruding piece for opening on the outside of the lower end of the part, and also has a projecting piece for opening on the outside of the lower end, the metal member covers the mouth part when the bottle container is covered with this sealing cap, and has a high barrier property. In addition to being able to obtain, there is also an advantage that design can be imparted by printing on the top surface of the metal member,
Furthermore, since the extending portion of the metal member on the side wall of the cap extends below the engaging projection of the synthetic resin member and the rigidity of the side wall is high, it is possible to securely seal the bottle container by a strong fitting force. It also has the effect of being able to do it.
