の他に多種使用されているが、内部に可燃性ガスが封入
されているので使用済の缶を火炎に投入すると内圧が異
常に高くなって爆発する。As is well known, air spray cans are used for a wide variety of purposes, including cosmetics, pesticides, and paints.However, since flammable gas is sealed inside, if a used can is thrown into a flame, the internal pressure will become abnormally high. explode.

又、コンデンサや消火器，その他内部に化学物質を封入

つたとき肉薄部分を破壊させるようにしたものが知られ
ている。Conventionally, as an explosion-proofing method for such a sealed container, a method is known in which a thin part is provided at the bottom or part of the side of the case, and the thin part is destroyed when the internal pressure increases abnormally. .

しかし肉薄部分を有するケースは物理的強度が低下する
ので取扱い時、成形時等において破損することがあり、
また体裁の悪いものとなる。However, cases with thin walls have reduced physical strength and may be damaged during handling, molding, etc.
It also looks bad.

更に容器の防爆機能は肉薄部分に存在するから、肉薄部
分の厚さが高精度でなければ防爆機能がなく、信頼性に
欠ける。Furthermore, since the explosion-proof function of the container exists in the thin wall portion, unless the thickness of the thin wall portion is highly accurate, there will be no explosion-proof function and the container will lack reliability.

又、使用済の容器を火炎に投入すると肉薄部分が融解し
たり破壊しないので、爆発する危険がある。Furthermore, if a used container is thrown into a flame, there is a risk of an explosion because the thin wall portion will not melt or break.

ケースを製造するようにしたものである。The present invention has been proposed in view of the above, has a simple structure, does not reduce physical strength, and is reliable by destroying the metal part when the internal pressure exceeds a certain level or when the temperature rises above a certain level. The company manufactures cases for sealed metal containers that are designed to prevent explosions.

部２又は側部３の一部にケース本体１より低融解点の金
属部４を設ける。The present invention will be described below with reference to the illustrated embodiment. A case body 1 for a closed container, which is formed by impact extrusion of aluminum, has a cylindrical shape with an open top, consisting of a bottom part 2 and a side part 3. A metal part 4 having a lower melting point than the case body 1 is provided in a part.

この金属部はケース本体と同種材質であって純度が異な
る合金か、又は他の種類の低融解点金属からなるもので
あって、低融解点金属であれば錫、鉛、これらの合金な
どで２００℃程度で融解する比較的軟質な金属が望まし
い。This metal part is made of an alloy of the same material as the case body but with a different purity, or is made of other types of low melting point metals, such as tin, lead, or alloys of these. A relatively soft metal that melts at about 200°C is desirable.

ケース本体１に上記した金属部４を設ける方法としては

ス本体１を作成する。The above-mentioned metal part 4 is provided in the case body 1 by forming small holes in the aluminum pellet when the case body 1 is cold extruded, embedding a small piece of aluminum alloy or a low melting point metal, and then applying the impact. The above pellets are placed inside a die (female die) of an extrusion machine, and impact extrusion is performed using a punch (male die) to create a cylindrical case body 1.

なおアルミニウムペレットに純度の異なるアルミニウム
合金又は低融解点金属の小片を埋設する方法としては溶
融金属を鋳込む方法、小片を小孔に装入する方法などが
ある。Methods for embedding small pieces of aluminum alloys or low melting point metals of different purity in aluminum pellets include a method of casting molten metal and a method of charging small pieces into small holes.

ムが延伸してダイとパンチとの狭い間隔に充満し、同時
にアルミニウム合金若しくは低融解点金属の小片も延伸
して底部又は側部の一部を構成する金属部４となる。When the aluminum pellet is impact extruded, the aluminum stretches and fills the narrow gap between the die and the punch, and at the same time a small piece of aluminum alloy or low melting point metal is also stretched to form the metal part 4 that forms part of the bottom or side part. becomes.

そして底部２又は側部３と金属部４との接合部５は冷間
圧接により接合して一体となるのであって、溶接その他
の強固な接続手段を使用していないので極端な強度がな
い。The joint 5 between the bottom part 2 or the side part 3 and the metal part 4 is joined together by cold pressure welding, and since no welding or other strong connection means is used, there is no extreme strength.

上記のようにしてなるケース本体に内容物を充填し、開
放上面を蓋材で閉止してエアースプレー、コンデンサ、
消化器などを構成すれば、内圧が基準以上に高くなった
とき接合部５が裂開し、内部のガスが放出するので爆発
を防ぐことができる。Fill the case body made as above with the contents, close the open top surface with a lid material, and use air spray, condenser, etc.
If a fire extinguisher or the like is configured, when the internal pressure becomes higher than a standard, the joint 5 will rupture and the internal gas will be released, thereby preventing an explosion.

又、上記容器を火炎に投入すると金属部４が融解して穿
孔するので、内部のガスが放出して爆発を防ぐことがで
きる。Further, when the container is thrown into a flame, the metal part 4 melts and perforates the container, so that the gas inside is released and an explosion can be prevented.

したがって本発明によれば金属部４が安全弁の機能を有
し、容器の内圧が基準以上に高くなっても、或は加熱さ
れても確実に防爆機能を果すことができ、危険のない容
器とすることかできる。Therefore, according to the present invention, the metal part 4 has the function of a safety valve, and even if the internal pressure of the container becomes higher than the standard, or even if it is heated, it can reliably perform the explosion-proof function, making it a risk-free container. I can do something.

しかもケース本体の底部や側部に肉薄な部分がないので
物理的強度が低下することがなく、ケース本体又は容器
とした場合に潰れたり破損することがないし、成形時に
高精度を要求することもない。Moreover, since there are no thin parts on the bottom or sides of the case body, the physical strength does not decrease, and when used as a case body or container, it will not be crushed or damaged, and high precision is required during molding. do not have.

このためあらゆる種類の密閉容器に利用することができ
、実用的価値の高いものとなる。Therefore, it can be used for all kinds of closed containers and has high practical value.
