Description

本発明は、発射薬が焼尽性ケースまたは布袋に充填された発射装薬を収納するための収納容器に関する。   The present invention relates to a storage container for storing a propellant filled with a propellant in a burnout case or a cloth bag.

大型火砲においては、弾丸とそれを発射するための火薬が別々に準備される形式のものがある。すなわち、この場合、砲に弾丸を装填した後に発射装薬を装填し、射撃する。発射装薬とは、焼尽性ケースまたは布袋に発射薬を充填した火工品であり、これは安全上や取り扱い上の要請から、保管時や運搬時には金属製の収納容器に収納されている。
このような状態にて保管・運搬されているとき、銃撃されて銃弾の衝撃が加えられたり、周囲が火災になり熱が加えられたりすることによって発射装薬が爆発（高速燃焼）した場合、収納容器が破壊されて多数の小さな破片となって飛び散ってしまうおそれがある。
そのような事態が生じた場合には、周辺人員を負傷死亡させたり、周辺設備や建造物を損傷させたり、他の発射装薬の収納容器にも破片が衝突して誘爆を生じたりして、二次災害を生じさせるおそれがある。 In large artillery, there is a type in which a bullet and gunpowder for firing it are prepared separately. That is, in this case, the bullet is loaded into the gun, and then the shooting charge is loaded and fired. The explosive charge is a pyrotechnic product in which a burnable case or a cloth bag is filled with a propellant, and is stored in a metal storage container at the time of storage and transportation for safety and handling requirements.
When it is stored and transported in such a state, if the projectile explodes (high-speed combustion) due to the impact of a bullet being fired or the surrounding area becoming a fire and heat being applied, There is a possibility that the storage container is destroyed and scattered as many small pieces.
If such a situation occurs, the surrounding personnel may be injured, the surrounding facilities and structures may be damaged, or a debris may collide with other propellant storage containers, resulting in an explosion. There is a risk of causing a secondary disaster.

特許文献１には、容器に脆弱部２８を有する爆発物の収納容器が開示されている。前記脆弱部は、収納容器の一部の爆発物が爆発したときに破壊されて開口し、それによって容器内の圧力が開放されることにより、他の爆発物の誘爆を防止するように作用するものである。   Patent Document 1 discloses an explosive storage container having a fragile portion 28 in the container. The fragile portion is destroyed and opened when a part of the explosive of the storage container explodes, thereby acting to prevent the explosion of other explosives by releasing the pressure in the container. Is.

特許文献２には、航空機による爆発物の輸送容器が開示されている。この輸送容器は、容器の壁面に構造的に脆弱な部分（フレーム７）が設けられており、当該容器内で爆発が起こったときに、前記脆弱部が破壊されて飛散し、開口されることで容器内の圧力が開放されるようになっている。   Patent Document 2 discloses a container for transporting explosives by aircraft. This transport container has a structurally fragile portion (frame 7) on the wall surface of the container, and when an explosion occurs in the container, the fragile portion is destroyed and scattered and opened. Thus, the pressure in the container is released.

特許文献３には、弾薬または弾薬ケースを局所衝撃から保護するためのスリーブが開示されており、局所衝撃からの保護手段としてスリーブの特定硬度を所定範囲に維持することが開示されている。   Patent Document 3 discloses a sleeve for protecting an ammunition or ammunition case from a local impact, and discloses that the specific hardness of the sleeve is maintained within a predetermined range as a protection means from the local impact.

特許文献１、２の発明では、容器に脆弱部を設けることは記載されているが、前記脆弱部自体を飛散させ難くすることや、小さな破片を生じさせないようにすることは記載されていない。
特許文献３の発明は、容器（スリーブ）自体を破壊し難くしたものであり、容器に脆弱部を設けることは全く記載されていない。 In the inventions of Patent Documents 1 and 2, it is described that the weak portion is provided in the container, but it is not described that the weak portion is difficult to be scattered or that small fragments are not generated.
The invention of Patent Document 3 makes it difficult to destroy the container (sleeve) itself, and does not describe any provision of a fragile portion in the container.

本発明は、衝撃や熱等を受けて収納された発射装薬が爆発したときにおいて、収納容器を所定の脆弱部において破壊させることにより、破壊による開口面積をできるだけ大きなものにして圧力を効果的に開放し、それ以上激しい反応が起きにくくするとともに、破片の飛散をできるだけ防止できる発射装薬の収納容器を提供することを課題とする。   In the present invention, when a propellant stored in response to impact or heat explodes, the storage container is broken at a predetermined fragile portion, thereby making the opening area by destruction as large as possible and effectively applying pressure. It is an object of the present invention to provide a container for a propellant charge which can be opened to the extent that it is difficult for a more intense reaction to occur and the scattering of fragments can be prevented as much as possible.

米軍規格MIL−STD−2105Bや火器弾薬技術ハンドブックには、次に示す５段階の安全性評価の指標が記載されている。
Ｉ 爆轟：火薬類がほとんどすべて瞬間的に反応し、容器は小さな破片にまで破壊しつくされる。
II 部分爆轟：火薬類が部分的に爆轟する。容器破片に小さなものが多く含まれる。
III 爆発：大破片が生成し、飛散する。
IV 爆燃：容器のほぼ全部が変形し破壊される。大き目の破片が生じる場合があるがその数は多くない。
V 燃焼：火薬が穏やかに燃焼し、容器が局所的に開放される。 The US military standard MIL-STD-2105B and the firearms ammunition technology handbook contain the following five levels of safety evaluation indicators.
I Detonation: Almost all explosives react instantaneously, and the container is destroyed to small pieces.
II Partial detonation: Explosives partially detonate. Container pieces contain many small items.
III Explosion: Large fragments are generated and scattered.
IV Deflagration: Almost all containers are deformed and destroyed. Large pieces may occur, but not many.
V Combustion: The gunpowder burns gently and the container is opened locally.

本発明は、上記の安全性評価の指標において、IVとVの間（Vに近いレベル）乃至はVを満たすようにしたものである。
本発明は、課題の解決手段として、筒体、筒体の両端部を閉塞する底部材と蓋部材を備えた発射装薬の収納容器であり、前記筒体が、内周面及び外周面の少なくとも一面において長さ方向に形成された螺旋状の脆弱部を有しているものである発射装薬の収納容器を提供する。 The present invention satisfies the above safety evaluation index between IV and V (a level close to V) or V.
As a means for solving the problem, the present invention is a container for a propellant charge including a cylindrical body, a bottom member that closes both ends of the cylindrical body, and a lid member, and the cylindrical body has an inner peripheral surface and an outer peripheral surface. Provided is a propellant storage container having a spiral weakened portion formed in a length direction on at least one surface.

本発明の発射装薬の収納容器は、何らかの原因により収容された発射装薬が爆発したときでも、螺旋状の脆弱部において破壊されるため、多数の破片が生じて飛び散ることがない。このため、保管及び運搬時の安全性が高められ、発射装薬が爆発したときでも、二次災害の発生が最小限に留められる。   Since the propellant storage container of the present invention is destroyed at the helical fragile portion even when the propellant accommodated for some reason explodes, a large number of fragments are not generated and scattered. For this reason, the safety at the time of storage and transportation is enhanced, and the occurrence of a secondary disaster is minimized even when the propellant explodes.

（１）図１に示す発射装薬の収納容器
発射装薬の収納容器１０は、鉄板、ステンレス板、アルミニウム板等の金属製のものであり、筒体１１と、筒体の両端の開口部を閉塞する底部材１２と蓋部材１３を備えている。 (1) The storage container 10 for the propellant charge shown in FIG. 1 is a metal container such as an iron plate, a stainless steel plate, or an aluminum plate, and has a cylindrical body 11 and openings at both ends of the cylindrical body. A bottom member 12 and a lid member 13 are provided.

底部材１２は、筒体１１に対して溶接で固定されていてもよいし、ねじ込み方式、クランプ等の固定具等を用いる方式にて開閉自在（着脱自在）に取り付けられていてもよいが、溶接固定することが望ましい。
蓋部材１３は、発射装薬の出し入れをするため、筒体１１に対してねじ込み方式、クランプ等の固定具等を用いる方式にて開閉自在（着脱自在）に取り付けることができる。
また蓋部材１３は、外周部材と内側蓋部材とからなり、外周部材が筒体１１に対して溶接で固定されており、内側蓋部材が外周部材に対してねじ込み方式、クランプ等の固定具等で開閉自在（着脱自在）に取り付けられていてもよい。発射装薬が爆発した際に筒体１１が脆弱部の位置で完全に分離してしまうことを防止するためには、蓋部材１３が外周部材と内側蓋部材とからなり、外周部材が筒体１１と溶接で固定されている方式が望ましい。 The bottom member 12 may be fixed to the cylinder 11 by welding, or may be attached in a freely openable / detachable manner by a screwing method, a method using a clamp or the like, It is desirable to fix by welding.
The lid member 13 can be attached to the cylindrical body 11 in a freely openable / closable (detachable) manner by using a screwing method, a fixing device such as a clamp, or the like in order to take in and out the propellant.
The lid member 13 includes an outer circumferential member and an inner lid member, and the outer circumferential member is fixed to the cylindrical body 11 by welding. The inner lid member is screwed to the outer circumferential member, a fixture such as a clamp, or the like. It may be attached so that it can be opened and closed freely (detachable). In order to prevent the cylinder 11 from being completely separated at the position of the fragile portion when the explosive charge explodes, the lid member 13 is composed of an outer circumferential member and an inner lid member, and the outer circumferential member is the cylindrical body. 11 and the method fixed by welding are desirable.

筒体１１は、内周面及び外周面の少なくとも一面において長さ方向に形成された螺旋状の脆弱部１６を有している。
筒体１１の外表面には文字を印刷したり、印刷物を貼り付けたりすることもあるため、脆弱部１６は内周面に形成されていることが好ましい。
脆弱部１６は、長さ方向に形成された螺旋状のものであるから、脆弱部が筒体１１全体に渡って均等に分散しており、特定の１箇所のみが極端に弱いわけではないので、運搬時等における外部からの衝撃（発射装薬を爆発させない程度の衝撃）に対して筒体１１は破損しにくく、容器として必要な機械強度を満たすことができる。 The cylindrical body 11 has a helical fragile portion 16 formed in the length direction on at least one of the inner peripheral surface and the outer peripheral surface.
Since characters may be printed on the outer surface of the cylindrical body 11 or a printed material may be attached, it is preferable that the fragile portion 16 is formed on the inner peripheral surface.
Since the fragile portions 16 are spirally formed in the length direction, the fragile portions are evenly distributed over the entire cylinder 11, and only one specific place is not extremely weak. The cylindrical body 11 is not easily damaged by an external impact during transportation or the like (impact that does not cause the explosive to explode), and can satisfy the mechanical strength required as a container.

脆弱部１６は、連続的に形成されていてもよいし、断続的に形成されていてもよいが、発射装薬が爆発したときに確実に破壊させるようにする観点からは、連続的に形成されていることが好ましい。ただし、断続的に形成された脆弱部１６を設けた場合は、容器としての機械強度を高くできる特徴があり、筒体１１を歪みの少ない円筒形状に製造しやすい特徴もあるので、この観点からは好ましい。なお、図１の脆弱部１６を示す破線は、脆弱部の形成位置を示すものであり、脆弱部１６が断続的に（不連続に）形成されていることを示すものではない。   The fragile portion 16 may be formed continuously or intermittently, but it is formed continuously from the viewpoint of reliably destroying the propellant when it explodes. It is preferable that However, in the case where the weakened portion 16 formed intermittently is provided, there is a feature that the mechanical strength as a container can be increased, and there is also a feature that the cylindrical body 11 can be easily manufactured into a cylindrical shape with less distortion. Is preferred. In addition, the broken line which shows the weak part 16 of FIG. 1 shows the formation position of the weak part, and does not show that the weak part 16 is formed intermittently (discontinuously).

次に、図１に示す発射装薬の収納容器１０の製造方法（組立方法）を図１、図２により説明する。   Next, a manufacturing method (assembling method) of the propellant storage container 10 shown in FIG. 1 will be described with reference to FIGS.

図２（ａ）に示すように、組立材料となる帯状金属板２１は、材質が鉄またはステンレスの場合、厚みが０．５〜２ｍｍ程度のものであり、材質がアルミニウムの場合、厚みが１〜４ｍｍ程度のものであって、幅方向の中央部において長さ方向に連続した脆弱部１６を有している。なお、脆弱部１６は、幅方向の中央部に形成されていることが好ましいが、辺２１ａ、２１ｂのいずれかの側に片寄って形成されていてもよい。
図２（ｂ）に示すように、脆弱部１６は他の部分よりも厚さの薄い部分（薄肉部）、溝等から形成されている。脆弱部１６は、図２（ｂ）で示される断面がＵ字状やＶ字状であってもよい。
帯状金属板２１の厚さが１ｍｍであるとき、脆弱部１６となる溝の深さは０．２〜０．５ｍｍ程度（即ち、薄肉部の厚さは０．５〜０．８ｍｍ程度）、また帯状金属板２１の厚さが２ｍｍであるとき、脆弱部１６となる溝の深さは０．４〜１ｍｍ程度（即ち、薄肉部の厚さは１〜１．６ｍｍ程度）にすることができる。 As shown in FIG. 2 (a), the band-shaped metal plate 21 as an assembly material has a thickness of about 0.5 to 2 mm when the material is iron or stainless steel, and the thickness is 1 when the material is aluminum. It has a width of about 4 mm and has a fragile portion 16 continuous in the length direction at the center in the width direction. In addition, although it is preferable that the weak part 16 is formed in the center part of the width direction, you may offset and form in the side of either side 21a, 21b.
As shown in FIG. 2B, the fragile portion 16 is formed of a portion (thin wall portion), a groove, etc. that is thinner than other portions. The weakened portion 16 may have a U-shaped or V-shaped cross section shown in FIG.
When the thickness of the strip-shaped metal plate 21 is 1 mm, the depth of the groove that becomes the fragile portion 16 is about 0.2 to 0.5 mm (that is, the thickness of the thin portion is about 0.5 to 0.8 mm), Moreover, when the thickness of the strip-shaped metal plate 21 is 2 mm, the depth of the groove that becomes the fragile portion 16 should be about 0.4 to 1 mm (that is, the thickness of the thin portion is about 1 to 1.6 mm). it can.

帯状金属板２１は、脆弱部１６が内側になるようにして螺旋状に巻いて行き、筒体を形成する。このように螺旋状に巻いて筒体を形成したとき、帯状金属板２１の辺２１ａと辺２１ｂが当接しているため、この当接部分を溶接（溶接部１５）により一体化して筒体１１を得る。
なお、脆弱部１６が外側になるようにして螺旋状に巻いて筒体１１を形成してもよい。
また、脆弱部１６が形成されていない帯状金属板２１を使用して筒体１１を得た後、脆弱部１６を形成することもできる。 The band-shaped metal plate 21 is spirally wound so that the fragile portion 16 is on the inside to form a cylindrical body. When the cylindrical body is formed by being spirally wound in this way, the side 21a and the side 21b of the belt-shaped metal plate 21 are in contact with each other. Therefore, the contact portion is integrated by welding (welded portion 15) to form the cylindrical body 11. Get.
Note that the cylindrical body 11 may be formed by spirally winding the fragile portion 16 on the outside.
Moreover, after obtaining the cylinder 11 using the strip | belt-shaped metal plate 21 in which the weak part 16 is not formed, the weak part 16 can also be formed.

その後、筒体１１の一端側開口部に底部材１２を溶接固定し、他端開口部側に蓋部材１３を着脱自在（開閉自在）に取り付ける。他端開口部側には、外周部材と内側蓋部材とからなる蓋部材１３の外周部材を溶接にて取り付けることもできる。   Then, the bottom member 12 is fixed by welding to the opening on one end side of the cylindrical body 11, and the lid member 13 is detachably attached (openable and closable) to the opening on the other end. The outer peripheral member of the cover member 13 which consists of an outer peripheral member and an inner side cover member can also be attached to the other end opening part side by welding.

図１に示す発射装薬の収納容器１０に対して外部から衝撃（特に銃弾貫通等による局部への衝撃）が加えられたり、周囲にて火災等が生じたりして、内部の発射装薬が爆発したときについて説明する。   An impact (especially a local impact due to bullet penetration, etc.) is applied from the outside to the propellant storage container 10 shown in FIG. Explain when it exploded.

このとき収納容器１０は、螺旋状の脆弱部１６において一体に破壊されるため、多数の破片、特に小さな破片となって飛び散るような事態が生じることはない。
また、脆弱部１６が螺旋状に大きく開口して燃焼圧力を開放するように作用するため、激しい反応が抑えられ、多数の破片、特に小さな破片となって飛び散るような事態の発生防止に役立つ。これは圧力が高いほど反応が激しくなるが、圧力が低いうちは穏やかに反応が進行するという火薬の一般的な性質によるものである。
よって、収納容器１０は、上記した安全性評価の指標において、IVとVの間（Vに近いレベル）乃至はVを満たすことができ、二次災害を防止することができる。 At this time, the storage container 10 is integrally broken at the spiral weakened portion 16, so that a situation in which a large number of pieces, particularly small pieces are scattered, does not occur.
In addition, since the fragile portion 16 opens large in a spiral shape and acts so as to release the combustion pressure, vigorous reaction is suppressed, and it is useful for preventing the occurrence of a situation in which a large number of pieces, particularly small pieces, are scattered. This is due to the general nature of explosives, where the higher the pressure, the more intense the reaction, but the lower the pressure, the milder the reaction proceeds.
Therefore, the storage container 10 can satisfy between IV and V (a level close to V) or V in the safety evaluation index described above, and can prevent a secondary disaster.

（２）図３に示す発射装薬の収納容器
発射装薬の収納容器１００は、鉄板、ステンレス板、アルミニウム板等の金属製のものであり、筒体１１１と、筒体の両端の開口部を閉塞する底部材１１２と蓋部材１１３を備えている。 (2) The storage container 100 for the propellant charge shown in FIG. 3 is a metal container such as an iron plate, a stainless steel plate, or an aluminum plate, and has a cylindrical body 111 and openings at both ends of the cylindrical body. A bottom member 112 and a lid member 113 are provided.

底部材１１２は、筒体１１１に対して溶接で固定されていてもよいし、ねじ込み方式、クランプ等の固定具等を用いる方式にて開閉自在（着脱自在）に取り付けられていてもよいが、溶接固定されていることが望ましい。
蓋部材１１３は、発射装薬の出し入れをするため、筒体１１１に対してねじ込み方式、クランプ等の固定具等を用いる方式にて開閉自在（着脱自在）に取り付けることができる。
また蓋部材１１３は、外周部材と内側蓋部材とからなり、外周部材が筒体１１１に対して溶接で固定されており、内側蓋部材が外周部材に対してねじ込み方式、クランプ等の固定具等で開閉自在（着脱自在）に取り付けられていてもよい。発射装薬が爆発した際に筒体１１１が脆弱部の位置で完全に分離してしまうことを防止するためには、蓋部材１１３が外周部材と内側蓋部材とからなり、外周部材が筒体１１１と溶接で固定されている方式が望ましい。 The bottom member 112 may be fixed to the cylindrical body 111 by welding, or may be attached to be freely opened and closed (detachable) by a screwing method, a method using a fixture such as a clamp, It is desirable to be fixed by welding.
The lid member 113 can be attached to the cylinder 111 in a freely openable / closable (detachable) manner by using a screwing method, a fixing tool such as a clamp, or the like, in order to take in and out the propellant.
The lid member 113 includes an outer circumferential member and an inner lid member, and the outer circumferential member is fixed to the cylindrical body 111 by welding. The inner lid member is screwed into the outer circumferential member, a fixture such as a clamp, or the like. It may be attached so that it can be opened and closed freely (detachable). In order to prevent the cylindrical body 111 from being completely separated at the position of the fragile portion when the propellant explodes, the lid member 113 is composed of an outer peripheral member and an inner lid member, and the outer peripheral member is the cylindrical body. A method of being fixed to 111 by welding is desirable.

筒体１１１は、内周面及び外周面の少なくとも一面において長さ方向に形成された螺旋状の脆弱部１１６を有している。
筒体１１１の外表面には文字を印刷したり、印刷物を貼り付けたりすることもあるため、脆弱部１１６は内周面に形成されていることが好ましい。
脆弱部１１６は長さ方向に形成された螺旋状のものであるから、脆弱部が筒体１１１全体に渡って均等に分散しており、特定の１箇所のみが極端に弱いわけではないので、運搬時等における外部からの衝撃（発射装薬を爆発させない程度の衝撃）に対して筒体１１１は破損しにくく、容器として必要な機械強度を満たすことができる。 The cylindrical body 111 has a spiral weakened portion 116 formed in the length direction on at least one of the inner peripheral surface and the outer peripheral surface.
Since characters may be printed on the outer surface of the cylindrical body 111 or a printed material may be attached, it is preferable that the fragile portion 116 is formed on the inner peripheral surface.
Since the fragile portions 116 are spirally formed in the length direction, the fragile portions are evenly distributed over the entire cylindrical body 111, and only one specific place is not extremely weak. The cylinder 111 is not easily damaged by an external impact during transportation or the like (impact that does not cause the explosive to explode), and can satisfy the mechanical strength required for the container.

脆弱部１１６は、連続的に形成されていてもよいし、断続的に形成されていてもよいが、発射装薬を爆発したときに確実に破壊させるようにする観点からは、連続的に形成されていることが好ましい。
脆弱部１１６に溶接する必要がある図５（ａ）又は図５（ｂ）に示した重ね合わせの場合は、脆弱部が連続的に形成されたものである必要がある。ただし、断続的に形成された脆弱部１１６を設けた場合は、容器としての機械強度を高くできる特徴があり、筒体１１１を歪みの少ない円筒形状に製造しやすい特徴もあるので、この観点からは断続的に形成された脆弱部１１６を設けることが好ましい。
なお、図３の脆弱部１１６を示す破線は、脆弱部の形成位置を示すものであり、脆弱部１１６が断続的に（不連続に）形成されていることを示すものではない。 The fragile portion 116 may be formed continuously or intermittently, but it is formed continuously from the viewpoint of reliably destroying the propellant when it explodes. It is preferable that
In the case of the overlapping shown in FIG. 5A or FIG. 5B that needs to be welded to the fragile portion 116, the fragile portion needs to be formed continuously. However, when the weakened portion 116 formed intermittently is provided, there is a feature that the mechanical strength as a container can be increased, and there is also a feature that the cylindrical body 111 can be easily manufactured into a cylindrical shape with less distortion. Is preferably provided with a weakened portion 116 formed intermittently.
Note that the broken line indicating the fragile portion 116 in FIG. 3 indicates the formation position of the fragile portion, and does not indicate that the fragile portion 116 is formed intermittently (discontinuously).

次に、図３に示す発射装薬の収納容器１０の製造方法（組立方法）を図３〜図５により説明する。   Next, a manufacturing method (assembling method) of the propellant storage container 10 shown in FIG. 3 will be described with reference to FIGS.

図４（ａ）に示すように、組立材料となる帯状金属板１２１は、材質が鉄またはステンレスの場合、厚みが０．５〜２ｍｍ程度のものであり、材質がアルミニウムの場合、厚みが１〜４ｍｍ程度のものであって、一辺側に薄肉部１２１ａが形成されており、薄肉部１２１ａを除く部分は均一厚さであり、他辺１２１ｂ側には薄肉部は形成されていない。
帯状金属板１２１の厚さが１ｍｍであるとき、薄肉部１２１ａの厚さは０．５〜０．８ｍｍ程度、また帯状金属板１２１の厚さが２ｍｍであるとき、脆弱部１１６となる溝の深さは０．４〜１ｍｍ程度（即ち、薄肉部の厚さは１〜１．６ｍｍ程度）にすることができる。 As shown in FIG. 4A, the band-shaped metal plate 121 as an assembly material has a thickness of about 0.5 to 2 mm when the material is iron or stainless steel, and the thickness is 1 when the material is aluminum. The thin portion 121a is formed on one side, the portion excluding the thin portion 121a has a uniform thickness, and no thin portion is formed on the other side 121b side.
When the thickness of the strip-shaped metal plate 121 is 1 mm, the thickness of the thin portion 121a is about 0.5 to 0.8 mm, and when the thickness of the strip-shaped metal plate 121 is 2 mm, the groove serving as the fragile portion 116 is formed. The depth can be about 0.4 to 1 mm (that is, the thickness of the thin portion is about 1 to 1.6 mm).

帯状金属板１２１は、薄肉部１２１ａが内側になるようにして螺旋状に巻いて行き、筒体を形成する。なお、薄肉部１２１ａが外側になるようにして螺旋状に巻いて筒体を形成してもよい。
このように螺旋状に巻いて筒体を形成したとき、図５に示すように帯状金属板１２１の薄肉部１２１ａと辺１２１ｂ側が当接しているため、この当接部分を溶接により一体化して筒体１１１を得る。但し、このときには薄肉部１２１ａの一部と辺１２１ｂ側を重ね合わせた状態で、重ね合わせ部分（溶接部１１５）のみを溶接する。
このようにして溶接部１１５において溶接することで、辺１２１ｂ側と溶接されていない薄肉部１２１ａの残部が脆弱部１１６となる。 The strip-shaped metal plate 121 is spirally wound so that the thin portion 121a is on the inner side to form a cylindrical body. Note that the cylindrical body may be formed by spirally winding the thin portion 121a on the outer side.
When the cylindrical body is formed by spirally winding in this way, the thin-walled portion 121a and the side 121b of the belt-shaped metal plate 121 are in contact with each other as shown in FIG. A body 111 is obtained. However, at this time, only the overlapping portion (welded portion 115) is welded in a state where a part of the thin portion 121a and the side 121b are overlapped.
By welding in the welded part 115 in this way, the remaining part of the thin part 121a that is not welded to the side 121b side becomes the weakened part 116.

その後、筒体１１１の一端側開口部に底部材１１２を溶接固定し、他端開口部側に蓋部材１１３を着脱自在（開閉自在）に取り付ける。他端開口部側には、外周部材と内側蓋部材とからなる蓋部材１１３の外周部材を溶接にて取り付けることもできる。   Thereafter, the bottom member 112 is welded and fixed to the opening on one end side of the cylinder 111, and the lid member 113 is detachably attached (openable and closable) to the opening on the other end. An outer peripheral member of a lid member 113 composed of an outer peripheral member and an inner lid member can be attached to the other end opening side by welding.

（３）他の発射装薬の収納容器
図１に示す収納容器１０、図２に示す収納容器１００は、いずれも帯状金属板２１、１２１を螺旋状に巻いた後、溶接して筒体１１、１１１を形成しているが、予め筒状に成形された筒体（但し、帯状金属板が螺旋状に巻かれたものは除く）を用いることもできる。 (3) Storage container for other propellant charge The storage container 10 shown in FIG. 1 and the storage container 100 shown in FIG. 2 are both wound and welded after the strip metal plates 21 and 121 are spirally wound. , 111 may be used, but a cylindrical body that has been formed into a cylindrical shape in advance (except that a belt-shaped metal plate is spirally wound) may be used.

予め筒状に成形された筒体は、周知のパイプの製造方法により製造することができるものである。   The cylindrical body previously formed into a cylindrical shape can be manufactured by a known pipe manufacturing method.

このような筒体（パイプ）の内周面や外周面に対して、切削加工等の方法により螺旋状に溝（薄肉部）を形成することで、図１に示す収納容器１０、図２に示す収納容器１００と同じ形状及び構造の発射装薬の収納容器を製造することができる。   By forming a groove (thin wall portion) in a spiral shape on the inner peripheral surface and outer peripheral surface of such a cylinder (pipe) by a method such as cutting, the storage container 10 shown in FIG. It is possible to manufacture a storage container for a projectile charge having the same shape and structure as the storage container 100 shown.
