Description

[Detailed description of the invention] This invention relates to a decorative cap made of synthetic resin.
The object is to use a metallic feel for decoration, and to have a simple structure and extremely easy assembly work.

Synthetic resin caps are often made with a metallic feel for decoration, but conventional decorative caps of this type have a cylindrical body with a metallic appearance that is assembled to the main body using caulking. In many cases, a transparent cover was integrally assembled onto the outer surface of the main body, which had metal plating or metal transfer applied to the surface.

Although the above-mentioned decorative cap exhibits a unique decorative effect, it has problems such as it takes time to manufacture, the assembly operation tends to be troublesome, and the metallic decoration tends to be monotonous. Ta.

For this reason, many techniques have been used to emphasize the metallic decoration by applying the metallic decoration not to the entire outer surface of the cap body, but to a part of the cap body, for example in the form of a ring. .

In many cases, this decoration means is easy to implement, and therefore a method has been adopted in which a ring-shaped metallic portion is transferred onto the outer surface of a cap body that has already been formed into a predetermined shape.

The above-mentioned conventional example is certainly easy to use.

It has the advantage of being able to form the metallic decorative part in almost the desired form, but it is extremely easy to remove the metallic ring part that has been transferred by contact with the reversed article or by repeatedly opening and closing the cap. This method has the disadvantage that it may peel off, and the scope of implementation is narrow because it may not be possible depending on the shape of the outer circumferential surface of the cap.

The present invention was devised in order to solve the drawbacks and problems of the above-mentioned caps having a decorative metallic ring. The cover is assembled to the main body by fixing, and the separately molded cover is assembled to the main body by fixing.

Embodiments of the present invention will be described below with reference to the drawings.

The decorative cap according to the present invention includes a main body 1 which is assembled into a container mouth 14 of a container such as a bottle and has a cylindrical shape with a capped plate that is spaced apart from the container mouth 14, and a peripheral body 3 of the main body 1. A decorative ring 11 having at least a metallic appearance is fitted and assembled to the lower end of the outer peripheral surface of the main body 1, and the decorative ring 11 is assembled to the main body 1 in a form that covers the outer surface above the lower end of the assembled main body 1. The cover unit 7 has a short cylindrical shape with a capped plate.

In the case of the illustrated embodiment, the main body 1 has a screw cap structure, and a thread 6 is formed on the inner peripheral surface of the circumferential body 3 to be threaded into a thread 15 formed on the outer peripheral surface of the container opening 14. There is.

A circumferential groove 4 is provided around the lower part of the outer circumferential surface of the circumferential barrel 3 of the main body 1 molded from synthetic resin, and a circumferential protrusion 5 is similarly provided at the lower end of the outer circumferential surface of the circumferential barrel 3. ing.

Decorative ring 1 fixedly fitted and assembled to the lower end of the circumferential body 3
1 has at least a metallic appearance, and is made of metal or synthetic resin and is plated with metal on the outer surface of the base body.

This decorative ring 11 has a step portion 12 formed at the lower end of the inner circumferential surface of its ring-shaped base to which the circumferential protrusion 5 is engaged from below, and the decorative ring 11 is fitted onto the main body 1 from above. By causing the circumferential protrusion 5 to engage with this stepped portion 12, the decorative ring 11 alone can be fitted and assembled into the main body 1.

The cover unit 7 has a short cylindrical shape with a top wall 8 having the same planar shape as the main body 1, and the peripheral wall 9 of the cover 7 is non-rotatably fitted to the circumferential body 3 of the main body 1. A locking protrusion 10 that engages with the circumferential groove 4 described above is provided on the lower end of the inner circumferential surface of the circumferential wall 9 in a protruding manner.

The height position of the locking protrusion 10 at the lower end of the inner peripheral surface of the peripheral wall 9 is determined by fitting and assembling the cover unit 7 to the main body 1 from above, so that the lower end surface of the peripheral wall 9 is A circumferential groove 4 is formed at a position where the decorative ring 11 is attached to the lower end of the circumferential barrel 3 with its stepped portion 12 locked to the circumferential protrusion 5.
It is set in the position where it engages with.

That is, the decorative ring 11 can be assembled to the main body 1 at the same time when the cover assembly 7 is assembled to the main body 1.

The cover unit 7, which is molded from synthetic resin, provides most of the appearance of the manufactured cap, and is not required to have the ability to assemble the cap to the container at all. Therefore, it is desirable to use a material that has excellent appearance, gloss, and scratch resistance, and it is generally advantageous to use a hard synthetic resin.

The assembly of the cover unit 7 to the main body 1 is as described above.
Fitting of the circumferential wall 9 to the circumferential body 3 and the circumferential groove 4 of the locking protrusion 10. This is achieved by engaging the top wall 8 with the top plate 2.
By making the cover 7 come into contact with the main body 1, the assembly of the cover 7 to the main body 1 becomes more stable.

By the way, as a means for achieving non-rotatable assembly of the cover unit 7 and the decorative ring 11 to the main body 1, as shown in the embodiment shown in FIG. shape, there is no need to take any special means to ensure that the assembly between them is unrotatable; however, in the case where the planar shape of the main body 1 is a perfect circle, 3, the outer circumferential surface of the circumferential barrel 3 and the inner circumferential surface of the circumferential wall 9 or the inner circumferential surface of the decorative ring 11 are configured to engage with each other in the circumferential direction, for example, a locking groove 16 and a locking strip 17. It is necessary to provide

In the case of the illustrated embodiment, a gasket 13 is attached to the main body 1 to more firmly seal the container. This can be done with a suitable configuration.

As described above, the decorative ring 11 constituting the cap according to the present invention is molded by itself, and has a metallic appearance by being made of metal or by being plated with metal, so it can be easily molded like a conventional transfer. There is no deterioration of the decorative effect due to peeling.

In addition, since the cover unit 7 only needs to be manufactured with consideration given to improving the appearance of the cap, a color, luster, and hardness that complements or matches the metallic feel of the decorative ring 11 can be freely selected. Since it can be used, the appearance of the cap can be made even more desirable.

Furthermore, the main body 1, the cover integrated 7, and the decorative ring 11
Each of them has an extremely simple structure, so it is easy to mold them, and the cover integral 7 and decorative ring 11 can be assembled to the main body 1 by simply fitting them together, and the decorative ring 11 is integral with the main body 1 and the cover. Since the assembly is held in a state where it is firmly held between the two members 7, the assembly is extremely stable, and therefore manufacturing and assembly are easy and can be accomplished satisfactorily.

As is clear from the above description, the present invention allows a ring-shaped decorative part with a metallic appearance to be applied with a high decorative effect without deteriorating the decorative effect, and is easy to manufacture and assemble. This cap has many excellent functions and effects as a decorative cap that is easy to apply and has a metallic feel.
