Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a container protected by a metal plate, which strengthens and enhances the decorativeness of all the various containers currently on the market.

PRIOR TECHNOLOGY There are an infinite number of containers made from various materials, but there is no one that covers them with a metal plate, so if there is some need, a part of the container can be made of metal. It is thought that the remaining parts will be manufactured from a material such as synthetic resin, and the two will be integrated by means such as adhesion, screwing, or fitting with grooves and protrusions. At present, in order to give a metallic impression to synthetic resins, some products are plated with metal or affixed with metal foil on the surface of the product to achieve this purpose.

Problems to be Solved by the Invention Just as the synthetic resins currently in use are clearly different from glass products, no matter how they are processed, they are clearly different from metal products. Although it is difficult to understand the difference in the plated plate, it is not possible to print on the surface after plating, so the range of industrial use cannot be said to be wide.

The present invention aims to achieve the usability, texture, and visual effects that were conventionally achieved with metal cans or containers by using synthetic resin and other materials covered with metal plates, and is less expensive than metal cans or containers. The aim is to obtain a product equivalent to that of

Looking at it from the other side, the purpose is to coat containers, which were conventionally manufactured only with synthetic resin or other materials, with metal plates, thereby increasing the commercial value of the containers.

The following are the problems that cans or containers made of only one of metal and synthetic resin are as follows.

Metal ones: 'D It is difficult to provide airtightness.

It is not possible to visually check the inside.

・■ Difficult to create thread grooves for screwing or fitting lids, etc. (especially, it is almost impossible to create thread grooves on the inside of containers, etc.).

Φ In cases other than press processing using aluminum, etc.,
A separately prepared bottom plate must be secured by wrapping or tightening.

Items made of synthetic resin: ■ It is difficult to print on the surface, and even if printing is possible, sufficient effects cannot be expected.

■ There are limits to the coloring of the materials themselves, making it difficult to supply products with colors that are considered desirable by consumers.

(L) Strength cannot be ensured unless the container has a certain thickness, and in most cases the container is too thick for containers that are considered to have no problems in terms of strength.

■ There is a widespread impression that synthetic resin products are naturally cheap, and there is no way to increase their own product value.
The feeling of use and texture cannot be said to be good at all.

These problems of metal products and synthetic resin products can be turned into advantages of synthetic resin products and metal products.
The inventor thought that by combining the two, a new value system could be created by manufacturing products more cheaply and easily.

Furthermore, when considering glass as a material, for example, it has been a problem that it has been desired to increase its strength at low cost but has not been achievable until now.

As a means to solve the problem and to combine the advantages of working metals, synthetic resins, and other materials, we considered manufacturing the base of the container from synthetic resin, etc., and covering the outer circumferential surface with a metal plate. .

At that time, a method of fitting a cylindrical metal tube onto a cylindrical synthetic resin base and gluing the two together was also considered.
This method was abandoned because it was impractical because the processing steps were complicated, it required mass production, and it increased the cost of the product.

The problem is solved as follows.

A covering metal plate is expanded into a cylindrical shape to match the outer diameter of the cylindrical base of the container to be coated to form a covering cylinder, and the base is inserted inside the covering cylinder, and the upper and lower edges of the covering cylinder are turned inward. Curl and tighten to press base 1, thereby fixing the covering tube to the base.

The covering tube is simply an extension of a metal plate, and there is no need to roll, weld, or glue opposing edges.

Also, the shape of the base is not limited to just a cylinder, but even if it is prismatic or truncated, the shape of the base can be adjusted by adding a covering tube to match the outer shape and curling the upper and lower edges. The present invention can be achieved regardless of the circumstances.

The sheathing tube is die-cut to a suitable shape before it is expanded, but the desired decorative effect can be obtained at any time by applying the necessary printing to the metal plate at an earlier stage.

Similarly, by pre-processing the base body or the cover plate, it is possible to obtain products that can achieve a variety of purposes.

For example, if a metal plate with appropriate holes is made in advance to form a covering cylinder, the base is made of highly transparent synthetic resin or glass, and the two are combined, the inside of the container can be seen through the holes. A product that can be visually recognized is obtained. Further, when a synthetic resin or glass container serving as a base is molded, if a thread groove is provided on the upper inner wall of the container, a container having an internal thread on the upper part can be obtained very easily.

Furthermore, when synthetic resin is used for the base, the thickness can be freely adjusted during the manufacturing stage, so the base can be manufactured as thin as possible.
By combining this with a covering tube, a lightweight product similar to a metal tube lined with synthetic resin can be obtained.

Example (1) The first example shown in Fig. M1 is an example in which a synthetic resin bottle is covered with a metal plate. In the figure, 1 is a synthetic resin base and 2 is a metal plate. It is a covered cylinder. In the illustrated example, the base body 1 has a cylindrical shape, and has an externally threaded ear neck N protruding from the upper end, and an internally threaded cap C on the ear neck N.
is screwed on. The covering tube 2 is attached to the base l as shown in FIG.
It is curved into a cylindrical shape that fits the cylindrical shape, and the opposing edges are brought so close that they touch each other, but they are not fixed by welding or the like, and there are curls at the top and bottom of the edges. A notch 3 is provided to obtain the necessary "negation" when tightening. 4 shows the curl tightening part.

An example of the curl tightening procedure is number 35! 3 (A), (B), (C), and (D).
A metal plate is bent to form a covering cylinder 2.

(B) Curl the lower end of the covering tube 2.

(C) Insert the base l into the covering tube 2.

(D) Curl the periphery of the end of the covering tube 2.

It shows the contents. This procedure is just an example, and the procedure may be changed arbitrarily if necessary in the manufacturing process.

(2) The second embodiment shown in FIG. 4 relates to a container that can hold 1M, and has reduced diameter portions 5 at the upper and lower ends of the base 1a so that the curl tightening portions 4 do not protrude dimensionally from the base 1a. is provided, and an internal thread S is pre-molded on the inner wall of the terminal end of the base body 1a. The covering tube 2 used for this is the same as that of the first embodiment, as shown in FIG. 5, and the curling procedure is also exactly the same as that of the first embodiment. The relative relationship between the reduced diameter part 5 and the curled part 4 is shown in FIG. 6 in the order of the processing steps.

(3) The one shown in Fig. 7 is a third embodiment in which the inside of the container can be visually checked, and a window 6 is provided in the covering tube 2a in advance.
This embodiment is the same as the second embodiment except that it is open and the base body 1b is molded from a highly transparent synthetic resin.

(4) The fourth embodiment shown in FIG. 9 is aimed at obtaining an extremely lightweight container. In the figure, the base body 1c is molded to be as thin as possible, and other aspects are the same as in the second embodiment.

In the explanation of the examples, we have mainly described cases in which synthetic resin is used for the base, but the material of the container serving as the base can be freely selected from synthetic resin, glass, ceramics, wood, etc. If the covering is considered to have utility value,
It can be applied to anything.

Effects of the invention According to the present invention, "printing on a metal plate" and "die cutting"
・ Manufacture is completed using common metal processing procedures called ``Kaisei'' and ``Curl tightening'', which brings out only the advantages of products such as synthetic resin and metal products, and completely eliminates the disadvantages.
