A head end 6 formed into a cylindrical body having the same diameter and connected to the shoulder 5 is integrally formed by drawing, forging, or the like.
この場合、頭端部６における軸線に平行する壁
肉部長さは、後述する胴部２との結合代が充分得
られる長さに形成する。 In this case, the wall portion of the head end 6 parallel to the axis is formed to a length that provides a sufficient connection margin with the body 2, which will be described later.
底部３は、頭部１の頭端部６と同一径に形成し
た底端部７と、当該底端部７に連接して底面部８

The corners 9 formed into arc-shaped curved surfaces are connected and integrally formed.

１２を被嵌して結合固定して設ける。 The body 2 has an end portion of a thin-walled cylindrical seal metal 10 whose outer diameter is the inner diameter of the head end 6, and the inner periphery of the head end 6 of the head 1 and the bottom end 7 of the bottom 3. A synthetic resin is provided by polymerizing and bonding, for example, with an adhesive, on each surface, and further has an end surface that contacts the end surface of the head end 6 and the end surface of the bottom end 7, and an inner peripheral surface that contacts the outer peripheral surface of the seal metal 10. The cylindrical body part 11 of the carbon fiber layered wall of the material is bonded, for example, with an adhesive, and the outer circumferential surface of the abutting surface of the head end 6 and the cylindrical body part 11 and the cylindrical body part 11 are provided.
A steel cylindrical ring 12 is fitted onto the outer peripheral surface of the abutting surface of the bottom end portion 7 and fixedly connected thereto.
この場合の筒体リング１２と頭端部６および底
端部７は、わずかな締代を有して嵌合させるよう

A single cylinder is formed by gluing so that there is no gap in the axial direction, and then a band-shaped carbon fiber is wound over and over again on the single cylinder, so that there is no gap in the axial direction. The seal metal 10 may be formed by gluing, or a band-shaped carbon fiber may be wound around another cylinder having the same outer diameter as the seal metal 10 in the axial direction many times without any gaps and then glued. The body may be removed to form the cylindrical body portion 11 having a layered wall made only of carbon fibers.
（作用）
この考案に係わる高圧ガスボンベでは、容器内
の封圧性は、シールメタルが司る。(Function) In the high-pressure gas cylinder according to this invention, the sealing metal controls the sealing pressure inside the container.
つまり、シールメタルと頭端部およびシールメ
タルと底端部の接合面で封圧し、高圧ガスボンベ
の耐圧性は、合成樹脂材の炭素繊維重層壁の筒体
部と筒体リングが受け持つ。 In other words, the pressure is sealed at the joint surfaces of the seal metal and the head end and the seal metal and the bottom end, and the pressure resistance of the high-pressure gas cylinder is taken care of by the cylindrical body part and the cylindrical body ring made of a carbon fiber layered wall made of a synthetic resin material.
さらに、胴部がシールメタルおよび筒体部と筒
体リングに置き代わるので、高圧ガスボンベの重
量は、従来の鋼製高圧ガスボンベに比して４分の
１弱に軽減される。 Furthermore, since the body is replaced by a seal metal, a cylindrical body, and a cylindrical ring, the weight of the high-pressure gas cylinder is reduced to a little less than one-fourth of that of a conventional steel high-pressure gas cylinder.
（効果）
この考案によれば、高圧ガスボンベの重量の大
部分をしめる胴部を合成樹脂材を併用して形成し
たので、高圧ガスボンベ単位の重量を従来の鋼製
高圧ガスボンベに比して４分の１弱に軽減するこ
とが可能となる。(Effects) According to this invention, the body, which contains most of the weight of the high-pressure gas cylinder, is formed using synthetic resin material, so the weight of the high-pressure gas cylinder unit is reduced to 4 times compared to conventional steel high-pressure gas cylinders. It is possible to reduce this to just under 1.
例えば従来の窒素ガスを充填して販売する場合
に使用する高圧ガスボンベは、約60キログラムで
あるが、この考案に係る高圧ガスボンベでは、同
一長さ同一径のもので、約15キログラムとなり、
約４分の１に軽減されるのである。 For example, a conventional high-pressure gas cylinder used to fill and sell nitrogen gas weighs approximately 60 kg, but the high-pressure gas cylinder according to this invention, which has the same length and diameter, weighs approximately 15 kg.
This is reduced to about one-fourth.
また、シールメタルと高強度の炭素繊維重層壁
の筒体部と補強用筒体リングを使用して形成した
ものでは、ガスの封圧力はシールメタルが負担
し、耐圧強度は筒体部と筒体リングが負担するの
で、鋼材を使用するシールメタルの重量を著しく
軽減することができる。 In addition, in a case formed using a seal metal, a cylinder made of a high-strength carbon fiber layered wall, and a reinforcing cylinder ring, the gas confinement pressure is borne by the seal metal, and the pressure resistance is the same as that of the cylinder. Since the weight is borne by the body ring, the weight of the seal metal made of steel can be significantly reduced.
また、解体分割の必要があれば、結合部から解
体することも可能である。 Furthermore, if it is necessary to disassemble and divide the parts, it is also possible to disassemble them starting from the joints.
また、製作が簡単となり、大量に生産すること
が容易になるので、運搬取扱いが簡便で、かつ廉
価である高圧ガスボンベの提供が可能となる。 In addition, since manufacturing is simple and mass production becomes easy, it is possible to provide a high-pressure gas cylinder that is easy to transport and handle and is inexpensive.
