Description

[0001]
[Industrial application fields]
The present invention relates to a stainless steel container for beverages equipped with a rubber protector.
[0002]
[Prior art]
Stainless steel containers are usually used for filling containers for various beverages including draft beer, and annular protectors are attached to the upper and lower edges of the container body. The protector covers the periphery of the upper and lower mirrors of the container body to protect the mirror surface, and the lower protector serves as a stand for placing the container body. The upper protector mounts the upper container during stacking. It will be a support seat to support.
[0003]
Conventionally, a stainless material made of the same material as the container body has been mainly used for the protector. Stainless steel protectors are usually welded to the upper and lower edges of a deep-drawn stainless steel container body, or the upper and lower mirrors are welded to the upper and lower inner peripheral surfaces of a stainless steel cylinder. There is also an example in which the protector part is formed above and below the upper and lower mirrors.
[0004]
In any case, when the protector is made of stainless steel, it is strong, but for example, when the draft beer is filled, the container becomes a considerable weight. For this reason, if the container is accidentally dropped during loading or unloading during transportation, or if it is violently collided with the floor, it will not only make noise, but the container will be deformed or damaged. In particular, when the container is tilted and dropped, the lower protector is locally deformed and cannot be placed in a normal upright posture, making stacking difficult.
[0005]
[Problems to be solved by the invention]
In order to solve the above problem, it is conceivable to use an annular rubber protector as the protector. An example in which a rubber protector is actually attached to the top and bottom of the container body is shown in registered design No. 635034 (for transportation) (see FIG. 11).
[0006]
In FIG. 11, when a rubber protector is used, a certain amount of thickness is required for the annular portion in order to maintain strength. Therefore, the protector 20 is placed on the smooth curved surfaces of the upper mirror 22 and the lower mirror 23 of the container body 21. It must be adhered to. 11 is a relatively elongated container, and the area of the upper mirror 22 and the lower mirror 23 is small, so that there is no particular problem in strength. However, in the beer barrel, when the container body is molded by deep drawing of a stainless steel plate, the body of the container is work hardened and its strength increases significantly. Because it is flat, there is almost no distortion, and it does not change from the strength of the stainless steel plate before processing.
[0007]
For this reason, when the rubber protector 30 is mounted on the upper and lower mirror surfaces with low strength as shown in FIG. 12, a load is applied from the vertical direction by stacking, or an impact is received from the rubber protector due to a fall or the like. Occasionally, the upper or lower mirror surface 31 of the mounting portion is depressed like 31 ', and depending on the degree of depression, the shape of the rubber protector 30 is collapsed and cannot be stacked, and the stability of the stationary is lacking. It will be.
[0008]
An object of the present invention is to provide a stainless steel container in which a mounting portion of a rubber protector is not easily deformed.
[0009]
To achieve the above object, in the stainless steel container according to the present invention, a stainless steel container having a rubber protector attached to the container body, having a rib,
The container body is made of austenitic stainless steel, and is a hollow container assembled by welding and joining at least two parts including the first molded body and the second molded body,
Each molded body is formed by deep drawing cold working into a shape including a mirror that is an upper base or a lower base and a cylindrical part that is open at one end that is a part of the body part,
The opening edges of the cylindrical portions of both molded bodies are joined directly or via an intermediate cylinder,
The rib has an arc shape and is welded to the outer peripheral region of at least one of the upper mirror and the lower mirror, and has a rising height within the range of the height of the protector and forms an angle on the mirror surface with respect to the mirror surface. It was raised and
The rising part of the rib is embedded in the rubber protector, supports the rubber protector on the surface of the rising part, disperses the external force, prevents the rubber protector from collapsing onto the mirror surface, and prevents the mirror protector from falling from the impact applied to the rubber protector. To prevent the sinking,
The rubber protector has an annular shape, is filled with a rib, and is bonded across the mirror surface and a part of the body.
[0010]
Moreover, the rubber protector is one in which a drain hole is opened in a part of the peripheral surface,
The ribs are arc-shaped segments and are arranged on the same circumference of the mirror surface except for the opening of the rubber protector.
[0012]
Further, in addition to the first rib projecting to the outer peripheral side of the mirror surface, the second rib projecting to the inner peripheral side,
The rising portion of the second rib supports deformation of the rubber protector that has fallen inward beyond the rising portion of the first rib.
[0013]
Further, the rib is formed in a mountain shape by two rising portions of the inner peripheral side and the outer peripheral side of the mirror surface,
The internal and external compatible upward portions support each other on the mirror surface and increase the mechanical strength of the rib, thereby forming a space not filled with rubber in the rib.
[0014]
The rising portion of the rib has a bent portion,
The bent portion of the rib is bent inward or outward of the mirror surface to increase the bonding strength to the rubber protector.
[0015]
In addition, a reinforcing material is attached to the rib,
The reinforcing material is in close contact with the surface of the rib facing the inner peripheral side of the mirror surface, and supports the rib from the inside to prevent its bending .
[0016]
[Action]
The rib is welded to the mirror surface, and supports the rubber protector at the rising portion to prevent the mirror surface from being depressed from an impact applied to the rubber protector. Since the rib is to be installed on the entire circumference of the mirror surface, it basically has an annular rising part, but if the rubber protector has a water drainage hole, cut that part. Use a circular arc. The rising portion of the rib is a portion that is raised at an angle in a right angle or inward and outward directions, and may be provided on one or two or more inside and outside. When two rising parts are provided, the rubber of the rubber protector is filled between the compatible rising parts, and the rubber protector is supported at each rising part.
[0017]
Further, if the two rising portions are supported on the mirror surface, the mechanical strength of the rib itself increases. Further, if the bent portion is provided at the rising portion, the bonding strength between the rib and the rubber protector is increased. In particular, when the bent portion inclined outward is provided, the rubber protector can be effectively prevented from falling down.
[0018]
In the case where a reinforcing material is attached to the rib, when a local force is applied to the rubber protector, the reinforcing material supports the inner surface of the rib and disperses the force, and the mirror surface is not depressed due to the local deformation of the rib. Be blocked.
[0019]
【Example】
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a via barrel to which the present invention is applied. In the embodiment, the container body 1 is a combination of the first molded body 2 and the second molded body 3, both of which are molded by deep drawing cold working of an austenitic stainless steel plate. The first molded body 2 is shaped into a shape including an upper mirror 4 and a cylindrical upper body portion 5, and the second molded body 3 is formed into a shape including a lower mirror 6 and a cylindrical lower body portion 7. It is shaped. Conventionally, the upper and lower body parts 5 and 7 are joined to each other at the opening edge of the cylinder to form the body part of the container body 1 and assembled into a hollow container having the upper mirror 4 as the upper bottom and the lower mirror 6 as the lower bottom. The same as the container body. When the intermediate cylinder is used, the opening edges of the cylindrical portions of both molded bodies are joined to the intermediate cylinder, respectively. A base 8 is attached to the center of the upper mirror 4.
[0020]
In the embodiment, welding ribs 9 a mirror peripheral region of the lower mirror 6, embedding the rib 9 in the rubber protector 10, by baking a rubber protector 10 across a part of the mirror surface and the lower torso portion 7 attached An example is shown. Two or more annular steps 11 are concentrically formed on the mirror surface of the upper mirror 4 in the outer peripheral region of the mirror, and a part of the mirror surface is formed from the center of the mirror toward the annular step 11 in the central region. An example is shown in which the ridges 12 are raised in a radial pattern to increase the strength of the mirror surface.
[0021]
In the embodiment, an example in which the rib 9 is provided on the lower mirror 6 will be described. However, the rib 9 can of course be provided on the upper mirror 4. When the annular step 11 or the radial protrusion 12 is formed on the mirror surface, processing distortion occurs due to the characteristics of the austenitic stainless steel plate, and the strength of the mirror surface increases. It will be shaped. However, in the case where the rib 9 is welded to the mirror surface, the mirror surface remains smooth.
[0022]
When attaching the rib, in FIG. 2 (a), in the case of the lower mirror 6, the mirror surface is inclined upward with a smooth curved surface from the center to the peripheral portion. The protruding rising portion is inclined toward the outer surface of the rubber protector. However, the angle formed by the rising portion of the rib with respect to the mirror surface is not limited at all. As shown in FIG. 3, it may stand up vertically, or may stand up inclined inward.
[0023]
FIG. 2B shows a planar shape and arrangement example of the ribs 9. The rib 9 is an annular shape having a rising height within the range of the height of the protector 10, but when attaching to the mirror surface, a drain hole that also serves as a handle is formed at the protector's main point. Since it is necessary to attach to the mirror surface except for the opening 13 of the hole, the arc-shaped segments are arranged and attached on the same circumference. This is the same even when the rib 9 is attached to the upper mirror 4. An example in which the rib 9 is attached to the upper mirror 4 is shown in FIG.
[0024]
In FIG. 2 (a), when the container is transported, particularly during loading and unloading, when the container collides with the floor and a force in the direction of the arrow is applied to the rubber protector 10, the protector 10 falls inward. At least within the extension length of the rib 9, the force applied to the protector 10 is supported by the surface of the rising portion of the rib 9 and does not directly act on the mirror surface. Since the force caused by the collapse of the rubber protector 10 is only applied to the mirror surface inside the rib 9, the mirror surface does not collapse unless it receives an excessively large force. In addition, since the rib 9 has an arc shape and is attached over a certain range of the outer peripheral area of the mirror surface, the external force is dispersed and no local force is applied to the mirror surface through the rib.
[0025]
FIG. 5 is an example in which two ribs are provided concentrically on the inner and outer sides. In addition to the rising portion of the first rib 9 projecting obliquely toward the outer peripheral side of the mirror surface, the rib protrudes on the inner peripheral side of the mirror surface. An example is shown in which the second ribs 14 having the rising portions are arranged side by side in an inclined manner. According to this structure, the deformation of the rubber protector 10 that has fallen inward beyond the rising portion of the first rib 9 is supported by the rising portion of the second rib 14 and local force is applied to the inner mirror surface. Little is added.
[0026]
FIG. 6 is an example using a chevron-shaped rib. This example also corresponds to the structure in which the two ribs of the first rib 9 and the second rib 14 are arranged side by side, but by welding both ends of the mountain-shaped rib to the mirror surface, Ascending portions with the second rib 14 support each other, and the mechanical strength of the rib itself increases. A space is formed between the ribs 9 and 14, but the rubber of the rubber protector 10 is not filled in the space.
[0027]
FIG. 7 is an example in which a bent portion 15 is provided at the rising portion of the rib 9. The bent portion 15 against the rising portion, the bond between the rubber and the ribs 9 of may be either inside or outside of the mirror surface, the bent portion 15 a rising portion of the at least a portion therefore in forming the rubber protector 10 The strength increases, and particularly when the mirror 15 is bent toward the outer peripheral side of the mirror surface as shown in FIG. 7, the bent portion 15 can prevent the rubber protector 10 from turning around and effectively prevent the collapse.
[0028]
Above, to the embodiment, it is attached to the ribs 9 or 9 and 14 to the mirror surface of the lower mirror 6 has been described an example embedded in the rubber protector 10, the ribs 9 or above mirror 4 as shown in FIG 9 , 14 is attached and embedded in the upper protector, or when the rib structure shown in FIGS. 5 to 7 is applied to the upper mirror 4, the operation is exactly the same. When applied to the upper protector, it is possible to effectively protect the mirror surface from the impact received from above during stacking, the impact received from the floor surface when installed in an inverted posture, and the impact when falling.
[0029]
However, in order to more effectively prevent the mirror surface from being depressed, it is desirable to further reinforce the rib itself. Even if the rib 9 is provided on the mirror surface, when the rib 9 is a simple circular ring, when the container falls or falls and the protector collides with a corner of the concrete, FIGS. 10 (a) and 10 (b) When a large external force F is applied locally as shown in FIG. 5, the rib 9 may be bent inward to deform the mirror surface.
[0030]
To prevent this phenomenon, it is possible to solve this problem by using thick ribs. However, for containers that are subject to restrictions on shape, size, weight, etc., such as via barrels, thick ribs can be used. If used, the weight increases, so it is difficult to employ thick ribs. In this embodiment, without increasing the weight, a lightweight and rigid reinforcing material is fitted into the inner periphery of the rib so as to adhere to the inner surface of the rib, and the rib is supported from the inside to prevent the bending thereof. . FIG. 8 shows an example in which a reinforcing member 16 is attached to the rib 9 of the lower protector shown in FIG. The reinforcing material 16 has an annular shape, and shows an example in which the reinforcing material 16 is fitted to the inner side of the rib 9 and attached to the inner surface of the rib 9 facing the inner peripheral side of the mirror surface.
[0031]
In the figure, the reinforcing member 16 has a rectangular cross-sectional shape. However, the reinforcing member 16 is not limited to a rectangular shape, and may be a trapezoidal shape or other rectangular shape as long as it can be in close contact with the inner surface of the rib 9. FIG. 9 is an example in which a reinforcing member 16 is attached to the rib 9 in the lower protector of FIG. In this example, the reinforcing material 16 having a trapezoidal cross-sectional shape is used, and the reinforcing material 16 is attached to the inner surface of the rib 9 inclined in the outer peripheral direction of the rubber protector 10 so that the inner surface of the reinforcing material 16 rises substantially vertically. Yes.
[0032]
The reinforcing material 16 is preferably made of FRP. FRP is lightweight, has springiness, has excellent resilience, and does not bend like metal. When a local external force F indicated by an arrow is applied to the rubber protector 10 as shown in FIG. 8 due to a drop or a fall of the container, the force F is applied to the rib 9 but is reinforced to support its inner surface. Since the force is dispersed by being received by the material 16 and the rib 9 itself does not fall down due to local deformation, it is possible to prevent local depression of the mirror surface.
[0033]
According to the present embodiment, the rib 9 prevents the rubber protector from collapsing and prevents the rib 9 itself from collapsing to prevent the mirror surface from collapsing locally. The weight can be reduced.
[0034]
【The invention's effect】
As described above, according to the present invention, the rib welded to the mirror surface is integrated with the mirror surface of the container body to exhibit rigidity and supports the protector, so that it falls down during transportation of the container and becomes a rubber protector. Even if a large impact force is applied locally, the mirror surface does not easily deform.
[0035]
The optimum cross-sectional shape of the rib is selected depending on the type and application of the container. However, if the rib has a simple shape, the rigidity of the mirror surface can be increased by attaching a reinforcing material to the inner surface of the rib.
[0036]
According to the present invention, the rigidity of the mirror surface of the container body can be easily increased without changing the shape, size, weight, and appearance of the container, and the manufacturing cost can be reduced. As widely available. The present invention is not limited to beer barrels and can be widely used for juice and other beverage filling containers.
