【0001】
【発明の属する技術分野】
本発明は耐圧容器に関する。さらに詳しくは、安全に廃棄することができる耐圧容器に関する。
【0002】
【従来の技術および発明が解決しようとする課題】
従来より、使用済のエアゾール容器やカセットコンロに使用されるガス容器などの耐圧容器を廃棄処分する場合には、廃品回収の作業の安全性のために、あらかじめ耐圧容器内に残留する内容物(原液と噴射ガス、または噴射ガスのみ)を排出することが消費者に望まれている。この内容物を排出する方法としては、一般に耐圧容器の底部に孔を明けて排出する方法と噴射ボタンを押し続けて排出する方法とがある。しかし、これらの排出方法では、排出作業が面倒であり、排出時に内容物が周囲に飛散するため、手や衣服などを汚したり、異臭を放つ惧れがある。このため、今なお、内容物が排出されずに廃棄される場合がある。
【0003】
そして誤って廃棄された耐圧容器が、たとえば図9に示されるように底部51、胴部52およびバルブ53を取り付ける肩部(目金部)54がそれぞれブリキ板などから別体につくられた3ピース缶の耐圧容器である場合、清掃車の巻込装置などにより胴部52を回転させながら押圧されると、胴部52と底部51を接合する巻締め部55および/または胴部52と肩部54を接合する巻締め部56から破壊されることがある。これは、前記巻締め部55を加工しやすくするために胴部52の円筒外表面とほぼ面一に形成するとともに、キャップ57を胴部52の外周面に沿って、保持させようとしているため、巻締め部56を胴部52の外径近傍部位に形成しており、外圧が巻締め部55、56に掛かりやすくなってしまったものと思われる。また、前記巻締め部は他の部分に比べて強度的に弱く、外力が加わると変形や破裂を起こしやすいからである。
【0004】
このため、巻締め部55および/または巻締め部56から噴出した内容物が可燃性である場合に、別の火種が引火して火災が発生する惧れがある。また内容物に粘着性が強く、臭いの強いものが含まれる場合では、周辺部を汚して異臭を放ったりする惧れがある。
【0005】
本発明は、叙上の事情に鑑み、安全に廃棄することができる耐圧容器を提供することを目的とする。
【0006】
【課題を解決するための手段】
本発明の耐圧容器は、円筒形状の容器本体の胴部の上端周縁部とバルブを取り付ける肩部の下端周縁部とが上部巻締め部により固着され、かつ前記容器本体の胴部の下端周縁部と底部とが下部巻締め部により固着されてなる耐圧容器であって、前記上部および下部巻締め部のうち、少なくとも一方の外径と前記胴部の外径との比が約0.7〜0.9にされてなることを特徴とする。
【0007】
また本発明の耐圧容器は、有底形状の容器本体の胴部の上部周縁部とバルブを取り付ける肩部の下端周縁部とが巻締め部により固着されされてなる耐圧容器であって、前記巻締め部の外径と前記胴部の外径との比が約0.7〜0.9にされてなることを特徴とする。
【0008】
また本発明の耐圧容器は、円筒形状の容器本体の胴部の上端開口部をしぼませて、カール部によりバルブが取り付けられ、前記容器本体の胴部の下端周縁部と底部とが巻締め部により固着されてなる耐圧容器であって、前記巻締め部の外径と前記胴部の外径との比が約0.7〜0.9にされてなることを特徴とする。
【0009】
また本発明の耐圧容器は、円筒形状の形上容器本体の胴部の上端周縁部とバルブの周縁部とが巻締め部により固着され、かつ前記容器本体の胴部の下端周縁部と底部とが下部巻締め部により固着されてなる耐圧容器であって、前記上部および下部巻締め部のうち、少なくとも一方の外径と前記胴部の外径との比が約0.7〜0.9にされてなることを特徴とする。
【0010】
さらに本発明の耐圧容器は、有底形状の容器本体の胴部の上部周縁部とバルブの周縁部とが巻締め部により固着されてなる耐圧容器であって、前記巻締め部の外径と前記胴部の外径との比が約0.7〜0.9にされてなることを特徴とする。
【0011】
【発明の実施の形態】
以下、添付図面に基づいて本発明の耐圧容器を説明する。
【0012】
図1は本発明の一実施の形態にかかわる耐圧容器を示す斜視図、図2は図1における耐圧容器の正面図、図3は図1における耐圧容器の断面図、図4は上部巻締め部の拡大図、図5は本発明の他の実施の形態にかかわる耐圧容器を示す断面図、図6は本発明のさらに他の実施の形態にかかわる耐圧容器を示す断面図、図7は本発明のさらなる他の実施の形態にかかわる耐圧容器を示す断面図、図8は本発明のさらなる他の実施の形態にかかわる耐圧容器を示す断面図である。
【0013】
図1〜3に示されるように、本発明の一実施の形態にかかわる耐圧容器であるエアゾール容器は、底部1、胴部2および肩部3からなる容器本体4と、バルブ5とから構成されている。前記容器本体4は、胴部2の上端周縁部と肩部3の下端周縁部とがニ重に巻締められた上部巻締め部6により固着されるとともに(図4参照)、胴部2の下端周縁部と底部1の周縁部とがニ重に巻締められた下部巻締め部7により固着されている。前記バルブ5は、肩部2の上端開口部に形成されるビード部に取り付けられるマウンティングカップ8と該マウンティングカップ8の中央内部に支持される噴射バルブ9とからなる。また本発明は、たとえば図5に示されるように、コンロ用ガス容器にも適用することができる。なお、図5において、10はコンロに固定するための方向規制部材である。
【0014】
本実施の形態では、前記上部巻締め部6および下部巻締め部7よりも胴部2を張り出させて、たとえば清掃車の巻込装置などにより押圧されても、胴部2の上下端部に形成される屈曲部2aの加工硬化により、胴部2の上下端部よりも中央部が先に窪み、上部および下部巻締め部6、7が破壊されないようにしている。すなわち、前記上部および下部巻締め部6、7の外径と胴部2の外径との比が、約0.7〜0.9、好ましくは約0.75〜0.85にされている。前記0.9をこえると、胴部が押圧され、変形するとき、屈曲部が小さいため、巻締め部にも押圧力が加わり、巻締め部が破壊するおそれがある。また前記0.7未満では、屈曲部を形成するためのしぼり加工がきつく、屈曲部の強度が弱くなり、巻締め部を保護できなくなるからである。
【0015】
なお、本実施の形態では、上部および下部巻締め部の外径が胴部の外径に対し、所定の比にされているが、本発明においては、胴部の上下端部のうち、少なくとも一方の巻締め部を所定の比にすることにより、押圧されたときに積極的に巻締め部よりも胴部の中央部から窪ませることもできる。
【0016】
前記耐圧容器の材料としては、鋼板、軽金属板などの任意の金属材料を用いることができる。
【0017】
また前記耐圧容器内の内容物としては、原液および噴射ガスからなるエアゾール組成物や噴射ガスなど、とくに限定されるものではなく、たとえば傷薬、かゆみ止め、点鼻薬、点耳薬、水虫薬、殺菌消毒剤、消炎鎮痛剤、制汗剤、害虫忌避剤、化粧水、プレ(アフター)シェーブローション、サンスクリーン剤などの人体用製品、ヘアスプレー、ヘアフォーム、トリートメントフォーム、クリームフォーム、フォームワックス、染毛剤、脱色剤、育毛剤、クレンジングなどの頭髪・頭皮用製品、殺虫剤、埃除去剤、消臭剤、芳香剤、ガラスやエアコンなどの洗浄剤、カセットコンロやランタンなどの燃料、ペイントなどの自動車・家庭用品撥水剤、錆止め、離型剤、コーティング剤、接着剤、潤滑剤などの工業用品などに用いられる。
【0018】
本実施の形態にかかわる耐圧容器では、バルブの取り付けは、胴部に肩部を介して取りつけられているが、本発明においては、これに限定されるものではなく、図6に示されるように、容器本体4の胴部2の上端周縁部とバルブ5の周縁部とが巻締め部6により固着されてなる耐圧容器とすることができる。この耐圧容器についても、胴部2の上下巻締め部6、7のうち、少なくとも一方の巻締め部を所定の比にすることができる。
【0019】
また本発明は、図7に示されるように、円筒形状の容器本体4の胴部2の上端開口部をしぼませて、カール部11にバルブ5のマウンティングカップ8をクリンチすることにより取り付けられ、かつ前記容器本体4の胴部2の下端周縁部と底部1とが巻締め部7により固着されている耐圧容器において、前記巻締め部7の外径と前記胴部2の外径との比を約0.7〜0.9になるようにすることができる。
【0020】
さらに本発明は、図8に示されるように耐圧容器が前記胴部2と底部21とが有底形状に一体に絞りしごき加工によって製造されるDI缶の場合にも適用することがきる。図8において、バルブ5が肩部3を介して胴部2に取り付けられているが、肩部を省いて取り付けることもできる。
【0021】
【発明の効果】
以上説明したとおり、本発明によれば、外圧により胴部が巻締め部より先に窪むように、所定の比で巻締め部よりも胴部を張り出させることにより、巻締め部からの内容物の噴出のおそれが少なくなるため、耐圧容器を安全に廃棄することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a pressure vessel. More specifically, the present invention relates to a pressure resistant container that can be safely discarded.
[0002]
[Background Art and Problems to be Solved by the Invention]
Conventionally, when disposing of pressure-resistant containers such as used aerosol containers and gas containers used for cassette stoves, the contents remaining in the pressure-resistant containers in advance for the safety of waste collection work ( It is desired by consumers to discharge stock solution and injection gas, or injection gas only). As a method for discharging the contents, there are generally a method in which a hole is formed in the bottom of the pressure vessel and a method in which the content is discharged by continuously pressing the injection button. However, in these discharge methods, the discharge work is troublesome, and the contents are scattered to the surroundings at the time of discharge, so there is a possibility that hands and clothes will be soiled and a strange odor may be emitted. For this reason, the contents may still be discarded without being discharged.
[0003]
Then, the pressure vessel which has been discarded by mistake, for example, as shown in FIG. 9, has a bottom 51, a trunk 52 and a shoulder (eye metal part) 54 to which a valve 53 is attached. In the case of a pressure vessel of a piece can, when it is pressed while rotating the trunk portion 52 by a winding device of a cleaning car or the like, the tightening portion 55 and / or the trunk portion 52 and the shoulder that join the trunk portion 52 and the bottom portion 51 are used. It may be broken from the tightening portion 56 that joins the portion 54. This is because the winding portion 55 is formed to be substantially flush with the cylindrical outer surface of the body portion 52 in order to facilitate processing, and the cap 57 is held along the outer peripheral surface of the body portion 52. The winding part 56 is formed in the vicinity of the outer diameter of the body part 52, and it seems that the external pressure is easily applied to the winding parts 55 and 56. In addition, the winding portion is weaker than other portions, and is easily deformed or ruptured when an external force is applied.
[0004]
For this reason, when the contents ejected from the tightening portion 55 and / or the tightening portion 56 are flammable, another fire type may catch fire and a fire may occur. In addition, when the contents are strongly sticky and have a strong odor, there is a risk that the peripheral part will be soiled and an unpleasant odor will be emitted.
[0005]
In view of the above circumstances, an object of the present invention is to provide a pressure-resistant container that can be safely discarded.
[0006]

[0007]
The pressure-resistant container of the present invention is a pressure-resistant container in which an upper peripheral edge of a body portion of a bottomed container body and a lower peripheral edge of a shoulder to which a valve is attached are fixed by a tightening portion. The ratio of the outer diameter of the fastening part and the outer diameter of the body part is about 0.7 to 0.9.
[0008]
The pressure-resistant container of the present invention is a cylinder-shaped container main body with its upper end opening squeezed, and a valve is attached by a curled portion, and the lower peripheral edge and the bottom of the container main body are wound together. And a ratio of the outer diameter of the tightening portion to the outer diameter of the body portion is about 0.7 to 0.9.
[0009]
Further, the pressure vessel of the present invention has a cylindrical shape, the upper peripheral edge of the body of the container main body and the peripheral edge of the valve are fixed by a tightening part, and the lower peripheral edge and bottom of the main body of the container main body. Is a pressure-resistant container fixed by a lower winding part, and a ratio of an outer diameter of at least one of the upper and lower winding parts to an outer diameter of the body part is about 0.7 to 0.9. It is characterized by being made.
[0010]
Furthermore, the pressure-resistant container of the present invention is a pressure-resistant container in which the upper peripheral portion of the body portion of the bottomed container body and the peripheral portion of the valve are fixed by a tightening portion, and the outer diameter of the tightening portion is The ratio with the outer diameter of the body is about 0.7 to 0.9.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the pressure vessel of the present invention will be described with reference to the accompanying drawings.
[0012]
1 is a perspective view showing a pressure vessel according to an embodiment of the present invention, FIG. 2 is a front view of the pressure vessel in FIG. 1, FIG. 3 is a sectional view of the pressure vessel in FIG. 1, and FIG. FIG. 5 is a cross-sectional view showing a pressure vessel according to another embodiment of the present invention, FIG. 6 is a cross-sectional view showing a pressure vessel according to still another embodiment of the present invention, and FIG. FIG. 8 is a cross-sectional view showing a pressure vessel according to still another embodiment of the present invention, and FIG. 8 is a cross-sectional view showing a pressure vessel according to still another embodiment of the present invention.
[0013]
As shown in FIGS. 1 to 3, an aerosol container, which is a pressure-resistant container according to an embodiment of the present invention, includes a container body 4 including a bottom part 1, a body part 2 and a shoulder part 3, and a valve 5. ing. The container body 4 is fixed by an upper tightening portion 6 in which the upper end peripheral portion of the body portion 2 and the lower end peripheral portion of the shoulder portion 3 are wound twice (see FIG. 4). The lower end peripheral part and the peripheral part of the bottom part 1 are fixed by a lower tightening part 7 that is double-tightened. The valve 5 includes a mounting cup 8 attached to a bead portion formed at the upper end opening of the shoulder portion 2 and an injection valve 9 supported in the center of the mounting cup 8. The present invention can also be applied to a stove gas container, for example, as shown in FIG. In addition, in FIG. 5, 10 is a direction control member for fixing to a stove.
[0014]
In the present embodiment, the upper and lower end portions of the body portion 2 even if the body portion 2 is protruded from the upper winding portion 6 and the lower winding portion 7 and pressed by, for example, a winding device of a cleaning vehicle. Due to the work hardening of the bent portion 2a formed in the upper portion, the central portion is recessed earlier than the upper and lower end portions of the body portion 2 so that the upper and lower winding tightening portions 6 and 7 are not destroyed. That is, the ratio of the outer diameter of the upper and lower winding tightening portions 6 and 7 to the outer diameter of the body portion 2 is about 0.7 to 0.9, preferably about 0.75 to 0.85. . When the value exceeds 0.9, the body part is pressed and deformed, and since the bent part is small, a pressing force is also applied to the wound part, and the wound part may be broken. Further, if the ratio is less than 0.7, the squeezing process for forming the bent portion is difficult, the strength of the bent portion is weakened, and the winding tightening portion cannot be protected.
[0015]
In the present embodiment, the outer diameters of the upper and lower tightening portions are set to a predetermined ratio with respect to the outer diameter of the trunk portion. By setting one of the tightening portions to a predetermined ratio, when pressed, it can be actively depressed from the central portion of the trunk portion rather than the tightening portion.
[0016]
As a material of the pressure vessel, an arbitrary metal material such as a steel plate or a light metal plate can be used.
[0017]
Further, the contents in the pressure vessel are not particularly limited, such as an aerosol composition consisting of a stock solution and a propellant gas, and a propellant gas. For example, wounds, itching prevention, nasal drops, ear drops, athlete's foot drugs, Disinfectant, anti-inflammatory analgesic, antiperspirant, pest repellent, lotion, pre-shave, sunscreen and other human products, hair spray, hair foam, treatment foam, cream foam, foam wax, Hair dyes, depigmenting agents, hair restorers, cleansing and other hair and scalp products, insecticides, dust removers, deodorants, fragrances, cleaning agents such as glass and air conditioners, fuel such as cassette stoves and lanterns, paint Used in industrial products such as water and water repellents for automobiles and household products, rust inhibitors, mold release agents, coating agents, adhesives, and lubricants.
[0018]
In the pressure resistant container according to the present embodiment, the valve is attached to the trunk portion via the shoulder portion. However, in the present invention, the invention is not limited to this, and as shown in FIG. In addition, a pressure-resistant container in which the upper peripheral edge of the body 2 of the container body 4 and the peripheral edge of the valve 5 are fixed by the tightening part 6 can be obtained. With respect to the pressure vessel, at least one of the upper and lower winding portions 6 and 7 of the body portion 2 can have a predetermined ratio.
[0019]
In addition, as shown in FIG. 7, the present invention is attached by squeezing the upper end opening of the body portion 2 of the cylindrical container body 4 and clinching the mounting cup 8 of the valve 5 to the curled portion 11. In the pressure-resistant container in which the lower end peripheral portion of the body portion 2 of the container body 4 and the bottom portion 1 are fixed by the tightening portion 7, the ratio between the outer diameter of the tightening portion 7 and the outer diameter of the body portion 2. Can be about 0.7 to 0.9.
[0020]
Furthermore, as shown in FIG. 8, the present invention can also be applied to the case where the pressure vessel is a DI can in which the body portion 2 and the bottom portion 21 are integrally formed into a bottomed shape by squeezing and ironing. In FIG. 8, the valve 5 is attached to the trunk portion 2 via the shoulder portion 3, but can be attached without the shoulder portion.
[0021]
【The invention's effect】
