Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device attached to the outer periphery of a high-pressure gas container to protect it from shock.

[0002]

[Prior art]

 Cylindrical high-pressure gas containers are widely distributed, for example, as containers for carbon dioxide gas used for beverages and liquefied gas used for fuel, etc. Frequent transportation and transfer due to refilling and the like easily cause fatigue. Also, the noise caused by a collision is noisy. In particular, relatively small aluminum alloy products are light in weight, so they are easy to handle roughly and are easily damaged. However, no measures have been taken to protect it.

[0003]

[Problems to be solved by the device]

 This invention was made in view of the above points, and its problem is to prevent damage to the high-pressure gas container, prolong its service life, reduce noise when handling the container, and make it easier to handle. is there.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention comprises a first ring 11 fitted to the outer periphery of the cylindrical container body 10 on the mouth side and a second ring 12 fitted to the outer periphery of the container body 10 on the bottom side. The first and second rings 11 and 12 which form a protection device are formed of a soft synthetic resin that elastically adheres to the outer periphery of the container body 10 into an annular shape with a constant width, and the second ring 12 is the container body. A flange portion 13 which is hooked on the bottom portion of the member 10 is integrally formed to have a substantially L-shaped cross section.

[0005]

[Action]

 In the device of the present invention, the first ring 11 is attached to the mouth side of the container body 10 formed in a cylindrical shape and the second ring 12 is attached to the bottom side, so that the container body 10 can be rolled or wall-mounted. When hit, the container body 10 does not collide with the floor or wall, and damage is prevented. The first and second rings 11 and 12 absorb the shock of the collision.

Both the first ring 11 and the second ring 12 are made of a soft synthetic resin and are in close contact with the container body 10, so that they are difficult to remove once they are attached. Further, even if the first and second rings 11 and 12 collide with the container body 10, no loud noise is generated, so that the problem of noise is solved.

【Example】

FIG. 1 shows an example in which the present invention is applied to a high pressure gas container made of aluminum alloy. The container body 10 is a relatively small cylindrical type having a bottom portion 15 at the lower end and a mouth portion 16 at the upper end, and is filled with, for example, carbon dioxide or nitrogen gas. The internal pressure is a high-pressure gas container with a commercial pressure of several hundred tens kg / cm ² .

The protective device of the present invention is a combination of a first ring 11 attached to the mouth portion 16 side of the container body 10 and a second ring 12 attached to the bottom portion 15 side.

Both the first ring 11 and the second ring 12 are molded from a soft synthetic resin so as to be in close contact with the outer circumference of the container body 10. Therefore, both rings 11 and 12 are shallow circular rings without any joints. As a material, a material that is easily deformed and is not easily damaged by an external force, such as polyethylene or soft vinyl chloride, other soft plastics and rubber, is used.

Both the first and second rings 11 have a diameter of about 200 mm in consideration of durability problems such as impact strength and the problem that if they are too thick, the diameter of the container becomes large and the packing density becomes rough. In the case of the above examples, a wall thickness of about 4 to 5 mm was optimum. In this case, the width (height) of the first and second rings 11 and 12 is about 10 times the wall thickness, which is about 1/10 of the cylindrical portion of the container body 10. The dimensions are sufficient for protection in terms of transportation and storage conditions.

Both the first ring 11 and the second ring 12 are provided with a thin portion 14 on the outer periphery of the upper end portion (on the side of the mouth portion 16). This protects the corners of each ring 11, 12 from damage, facilitates unfolding and facilitates attachment to the container body 10.

Further, a flange portion 13 protruding inward is integrally formed at the lower end portion (on the side of the bottom portion 15) of the second ring 12 so that the flange portion 13 can be hooked on the bottom portion 15. Due to the presence of the flange portion 13, the second ring 12 has a substantially L-shaped cross-section (FIG. 3B). Due to the flange portion 13, the second ring 12 protects the corner portion of the bottom portion 15 of the container body, which is particularly susceptible to external force.

The first ring 11 and the second ring 12 as described above are formed in an annular shape having an inner diameter slightly smaller than the outer diameter of the cylindrical portion of the container body 10 (even if the end portions are joined instead of molding). Good)), and by spreading it and fitting it into the container body 10, it is attached so as to elastically adhere to the outer periphery thereof (see FIG. 4). Further, the first and second rings 11 and 12 can have an effect of being distinguished by coloring and an effect of identifying. In addition, letters, symbols, and other figures may be formed on the surface of each ring to facilitate handling.

[0014]

[Effect of device]

 Since the present invention is constructed and operates as described above, it is possible to prevent damage to the high-pressure gas container, protect the relatively weak peripheral side surface, and prevent damage to the protective device. It can be replaced with a new one, and can be used safely until the original life of the container body is fulfilled, and it has the effect of significantly reducing impact noise and facilitating handling.
