方法に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stainless steel container having a rubber protector for beer and other beverages and a method for producing the same.

Description of the Related Art A stainless steel container is generally used as a filling container for transporting various drinks including draft beer, and an annular protector is attached to upper and lower edges of the container body. The protector covers around the upper mirror and lower mirror of the container body,
While protecting the mirror surface, the lower protector serves as a stand when the container body is fixed, and the upper protector serves as a support seat for supporting the upper container when stacking.

ロテクタ部分を形成する例もある。Conventionally, the protector is mainly made of the same stainless steel material as that of the container body. Stainless steel protectors are usually welded to the upper and lower edges of the deep drawn stainless steel container body,
Alternatively, there is an example in which an upper mirror and a lower mirror are welded to the upper and lower inner peripheral surfaces of a stainless steel cylinder to project above and below the upper mirror and the lower mirror to form a protector portion.

勢で安定に置くことができず、段積みが困難となる。[0004] In any case, when the protector is made of stainless steel, it is robust and beautiful, but when it is filled with draft beer, for example, the container becomes quite heavy. For this reason, if the container is accidentally dropped during loading or unloading during transportation, or if the container is hit hard on the floor, it will not only generate noise, but also deform or break the container. In particular, when the container is tilted and dropped, the protector is locally deformed and cannot be stably placed in a normal upright posture, which makes stacking difficult.

考えられる。実際に容器本体の上，下にゴムプロテクタ
を取付けた例が登録意匠第６３５０３４号（運搬用た
る）に示されている（図１１参照）。In order to solve the above problem, it is conceivable to use an annular rubber protector for the protector. An example in which a rubber protector is actually attached above and below the container body is shown in Registered Design No. 635034 (transporting barrel) (see FIG. 11).

の強度と変らない。In FIG. 11, when a rubber protector is used, the annular portion needs to have a certain thickness in order to maintain strength. Therefore, the protector 31 has a smooth shape of the upper mirror 33 and the lower mirror 34 of the container body 32. It has to be glued on a curved surface. The barrel in FIG. 11 is a relatively elongated container, and since the areas of the upper mirror 33 and the lower mirror 34 are small, it seems that there is no problem in terms of strength. However, in the case of a beer keg, when the container body 32 is formed by deep drawing of a stainless steel plate, the body of the container is hardened by work and the strength thereof is remarkably increased.
There is almost no distortion on the surface of the lower mirror, which is the same as the strength of the stainless steel plate before processing.

When an impact is applied, the upper mirror or lower mirror surface 41 of the mounting portion is depressed like 41 ', and depending on the degree of the impact, the mirror surface of the central portion where the rubber protector is not mounted is depressed and depressed. Depending on the degree, the shape of the rubber protector 40 may be collapsed to make it impossible to stack, and the stability of the posture may be lacking.

る。Further, when an annular rubber protector is used, the protector 4 is required to secure the adhesive strength.
The inner peripheral edge 40a of the protector 40 is extended in a divergent shape in the center direction and is joined to the smooth surface 41 of the mirror. As a result, there is a problem that the film is easily peeled off.

Although the number of ridges is not particularly limited, in the embodiment, eight ridges are formed radially around the mounting portion of the base 8. In addition, the shape is not specified, but the point is to increase the strength of the mirror surface by causing work hardening by cold working in the radial direction from the center of the mirror surface to the periphery.

2, the strength of the mirror surface as a whole is increased. However, the annular rib 21 is formed in the outer peripheral area serving as the bonding surface of the rubber protector 25, and the radial rib 22 is provided in the central area where the rubber protector 25 is not attached. What was formed is that the vertical load from the rubber protector 25 is supported on the annular rib 21 to prevent the depression that occurs in the circumferential direction, and the important part of the annular rib 21 is supported by the radial rib 22 from the radial direction, and the rubber protector falls down. This is to prevent the depression generated on the inner peripheral side of the mirror surface due to the pressure of the mirror surface or the shearing force applied to the mirror surface.

As a whole, a stainless steel container can be provided in which the strength of the stainless steel container is improved, the mirror surface is not depressed by an external force applied to the mirror surface through the rubber protector, and is not deformed even after long-term use. Also,
Since the inner peripheral edge of the rubber protector is received in the step to secure the thickness of the terminal, the adhesive strength is increased and the rubber protector is not peeled off.

It is desirable that the steps provided on the reinforcing plate 26 be set at the same pitch as each step of the annular rib formed on the mirror surface. Thereby, the reinforcing plate 26 can be brought into close contact with the mirror surface. However, in order to keep the gap between the reinforcing plate 26 and the mirror surface constant,
Protrusions (not shown) may be provided at key points of the reinforcing plate 26, and the protrusions may be seated on a mirror surface. In this case, at the time of molding the rubber protector, the rubber enters the gap and the reinforcing plate 26 is embedded in the rubber protector 25 at a position close to the mirror surface,
Rubber can be filled in the space of the gap while expelling the air in the gap between the two.

The force is dispersed by the reinforcing plate 26 so that no depression occurs at a specific portion of the mirror surface.

As is apparent from the figure, the strength (c) of the mirror surface of the portion where the rubber protector is mounted in the case where the reinforcing plate is stacked on the mirror surface is larger than the strength (a) of the second embodiment. It can be seen that the strength of the sample has increased significantly.

By forming the radial ribs that support the annular ribs from the center direction on the mirror surface, the strength of the mirror surface is improved as a whole, and the reinforcing plate is embedded in the protector to support the external force. Thus, it is possible to provide a stainless steel container which is not depressed even when an external force is applied to the mirror surface through the rubber protector and which is not deformed even after long-term use.
