スプレー缶の圧抜き構造Pressure release structure of spray can

本発明は、化粧品、塗料、又はプロパンガス等を圧縮充填しておいて噴出させるスプレー缶の圧抜き構造に関する。   The present invention relates to a pressure relief structure for a spray can that is compressed and filled with cosmetics, paint, propane gas, or the like.

従来から、化粧品等の流体をスプレー缶に充填して販売している。図4に、このスプレー缶の一例として、化粧品のスプレー缶101を示す。スプレー缶101は、化粧品(流体)102を圧縮して入れる密閉缶体103と、この化粧品102を外部へ導く噴出経路104と、この噴出経路104を閉鎖又は開放する開閉手段105とを備えている。噴出経路104は、図5に示すように、密閉缶体103内の化粧品102内に通じるパイプ106と、外部に通じる噴出口107と、パイプ106及び噴出口107を連結する連結経路108とを備えている。連結経路108は、パイプ106を支持するパイプ支持部材109の中空部110と、パイプ支持部材109に挿入された移動部材111の中空部112とから構成される。開閉手段105は、中空部110と中空部112との連結部を閉鎖するパッキン113と、移動部材111を押し下げてパッキン113による閉鎖を開放する押圧部材114とから構成されている。このスプレー缶101は、パッキン113によって噴出経路104を閉鎖して密閉する一方で、使用時には、図6に示すように、押圧部材114を指115で押し下げてパッキン113を変形させ、噴出経路104を開放して化粧品102を外部へ噴出させることができる。 Conventionally, cosmetics and other fluids are filled in spray cans and sold. FIG. 4 shows a cosmetic spray can 101 as an example of the spray can. The spray can 101 includes a sealed can body 103 into which cosmetics (fluid) 102 is compressed, a jetting path 104 that guides the cosmetics 102 to the outside, and an opening / closing means 105 that closes or opens the jetting path 104. . As shown in FIG. 5 , the ejection path 104 includes a pipe 106 that communicates with the cosmetic product 102 in the sealed can body 103, a spout 107 that communicates with the outside, and a connection path 108 that couples the pipe 106 and the spout 107. ing. The connection path 108 includes a hollow portion 110 of the pipe support member 109 that supports the pipe 106 and a hollow portion 112 of the moving member 111 inserted into the pipe support member 109. The opening / closing means 105 includes a packing 113 that closes the connecting portion between the hollow portion 110 and the hollow portion 112, and a pressing member 114 that pushes down the moving member 111 to open the closing by the packing 113. While the spray can 101 closes and seals the ejection path 104 with the packing 113, in use, as shown in FIG. 6 , as shown in FIG. The cosmetic 102 can be ejected to the outside by opening.

このようなスプレー缶101は、廃棄する場合には、多少残っているガスの暴発を防止するために、押圧部材114を指115で押し下げて化粧品102を殆ど全て噴出させることにより、密閉缶体103内の圧力を抜いて外部圧力と略同じにしていた。しかし、このようにして圧力を抜くには時間がかかった。また、密閉缶体103に孔を開けることによって密閉缶体103内の圧力を抜くこともあった。しかし、この場合には、工具を使用して困難な作業を行う必要があり、専用装置を使用する場合にはコストが必要となった。   When such a spray can 101 is discarded, in order to prevent the remaining gas from exploding somewhat, the pressing member 114 is pushed down with a finger 115 to eject almost all of the cosmetic 102, thereby closing the sealed can 103. The internal pressure was released to make it almost the same as the external pressure. However, it took time to release the pressure in this way. Further, the pressure in the sealed can body 103 may be released by opening a hole in the sealed can body 103. However, in this case, it is necessary to perform a difficult operation using a tool, and a cost is required when using a dedicated device.

そこで、本発明者は、スプレー缶の圧抜き構造に関して、さらに鋭意研究を重ねた結果、本発明に至ったのである。すなわち、本発明は、使用済のスプレー缶を廃棄する際に、スプレー缶の内圧を、容易、迅速かつ安全に抜くようにすることを目的とする。   Therefore, the inventor of the present invention has made the present invention as a result of further earnest research on the pressure relief structure of the spray can. That is, an object of the present invention is to easily, quickly and safely release the internal pressure of the spray can when the used spray can is discarded.

The present invention provides a sealed can body that compresses fluid, an ejection path that guides the fluid in the sealed can body to the outside, open / close means that closes or opens the ejection path, and maintains the ejection path in an open state. A pressure relief structure of a spray can comprising:
The ejection path is composed of a pipe that communicates with the inside of the sealed can, an ejection opening that communicates with the outside, and a coupling path that connects the pipe and the ejection port.
The connection path includes a hollow portion of a pipe support member that supports the pipe, and a hollow portion of a moving member that is inserted into the pipe support member.
The opening / closing means is composed of a packing that closes a connecting portion between the hollow portion of the pipe support member and the hollow portion of the moving member, and a pressing member that pushes down the moving member to open the closing by the packing,
A guard is attached to the caulking projection of the sealed can so as to surround the pressing member, one end of the pressing member is connected to the guard via a flexible connecting portion, and a lever is connected to the other end of the pressing member. Provided,
The open maintaining means is composed of a convex portion provided on the lever, and a locking projection provided on the guard,
The lever is pushed down to engage the convex portion below the locking projection, thereby maintaining the ejection path open and releasing the pressure in the sealed can body to the outside.

開放維持手段を備える本発明のスプレー缶の圧抜き構造によれば、噴出経路が開放した状態で維持できる。このため、スプレー缶を廃棄する際には、噴出経路が開放した状態に維持して放置するのみで圧力を抜くことができる。 According to the pressure relief structure of the spray can of the present invention provided with the opening maintaining means, the ejection path can be maintained in an open state. For this reason, when disposing of the spray can, the pressure can be released only by leaving the spray path in an open state.

しかも、この開放維持手段が、押圧部材のレバーに設けられた凸部と、ガードに設けられた係止突起とから構成されており、押圧部材がガードに可撓連結部を介して連結されているので、レバーを押し込んで凸部を簡単に係止突起の下方に係合させることができ、押圧部材の押圧状態が維持されて噴出経路を開放した状態に維持することができる。また、かしめ突起を有する従来の密閉缶体に適用できるので、ガード及び押圧部材を用意しさえすれば、従来の密閉缶体に対する圧抜き作業を行うことができる。In addition, the opening maintaining means is composed of a convex portion provided on the lever of the pressing member and a locking projection provided on the guard, and the pressing member is connected to the guard via a flexible connecting portion. Therefore, the lever can be pushed in and the convex portion can be easily engaged below the locking projection, and the pressing state of the pressing member can be maintained and the ejection path can be kept open. Moreover, since it can apply to the conventional sealed can body which has a crimping protrusion, if only a guard and a press member are prepared, the pressure release operation | work with respect to the conventional sealed can body can be performed.

まず、図1及び図2を参照しながら、従来の圧抜き構造を備えたスプレー缶について説明し、その後、図3を参照しながら、本願発明に係るスプレー缶の圧抜き構造について説明する。First, a spray can having a conventional pressure relief structure will be described with reference to FIGS. 1 and 2, and then, a pressure relief structure for a spray can according to the present invention will be described with reference to FIG. 3.

図1及び図2に示す、スプレー缶200は、ヘアトリートメント等の化粧品(流体)を圧縮して入れる密閉缶体14と、密閉缶体14内の化粧品を外部へ導く噴出経路16と、噴出経路16を閉鎖又は開放する開閉手段18と、噴出経路16を開放した状態に維持する開放維持手段202とを備えている。開放維持手段202がスプレー缶の圧抜き構造として機能する。 A spray can 200 shown in FIGS. 1 and 2 includes a sealed can body 14 into which cosmetics (fluid) such as a hair treatment is compressed, an ejection path 16 that guides the cosmetics in the sealed can body 14 to the outside, and an ejection path. An opening / closing means 18 for closing or opening 16 and an opening maintaining means 202 for maintaining the ejection path 16 in an opened state are provided. The opening maintaining means 202 functions as a pressure release structure for the spray can.

噴出経路16は、密閉缶体14内の化粧品内に通じるパイプ22と、外部に通じる噴出口24と、パイプ22及び噴出口24を連結する連結経路26とを備えている。連結経路26は、パイプ22を支持するパイプ支持部材28の中空部30と、パイプ支持部材28に挿入された移動部材32の中空部34とから構成される。開閉手段18は、中空部30と中空部34との連結部を閉鎖するパッキン36と、移動部材32を押し下げてパッキン36による閉鎖を開放する押圧部材38とから構成されている。   The ejection path 16 includes a pipe 22 that communicates with the cosmetic in the sealed can body 14, a spout 24 that communicates with the outside, and a connection path 26 that connects the pipe 22 and the spout 24. The connection path 26 includes a hollow portion 30 of the pipe support member 28 that supports the pipe 22 and a hollow portion 34 of the moving member 32 inserted into the pipe support member 28. The opening / closing means 18 includes a packing 36 that closes the connecting portion between the hollow portion 30 and the hollow portion 34, and a pressing member 38 that pushes down the moving member 32 to open the closing by the packing 36.

開放維持手段202は、移動部材32のまわりに回動可能な押圧部材38に設けられた2個の凸部204と、密閉缶体14に設けられた2個の爪部206とから構成されている。   The opening maintaining means 202 includes two convex portions 204 provided on the pressing member 38 that can rotate around the moving member 32, and two claw portions 206 provided on the sealed can body 14. Yes.

このスプレー缶200は、化粧品用等として通常に使用する場合には、押圧部材38を押圧して移動部材32を下へ移動させることにより、移動部材32に係合されているパッキン36が変形し、中空部30と中空部34とが通じることとなる。中空部30と中空部34とが通じることにより、密閉缶体14内の圧力によって、化粧品がパイプ22から中空部30及び34を通って噴出口24から噴出する。   When the spray can 200 is normally used for cosmetics or the like, the packing 36 engaged with the moving member 32 is deformed by pressing the pressing member 38 and moving the moving member 32 downward. The hollow portion 30 and the hollow portion 34 communicate with each other. By the communication between the hollow portion 30 and the hollow portion 34, the cosmetic is ejected from the jet port 24 through the hollow portions 30 and 34 from the pipe 22 due to the pressure in the sealed can body 14.

次に、スプレー缶200が使用済となり、スプレー缶200を廃棄する場合、押圧部材38を90°回動させ、押圧部材を押圧して移動部材32を下へ移動させた状態で、図2(a)に示すように、凸部204を爪部206の下に係合させる。凸部204を爪部206の下に係合させることにより、図2(b)に示すように、パッキン36が変形して中空部30と中空部34とが通じる状態が維持される。中空部30と中空部34とが通じる状態が維持されることにより、押圧部材38から手を離して放置しておいても、化粧品がパイプ22から中空部30及び34を通って噴出口24から噴出し続け、密閉缶体14内の圧力が自動的に抜かれていく。   Next, when the spray can 200 becomes used and the spray can 200 is discarded, the pressing member 38 is rotated by 90 °, the pressing member is pressed, and the moving member 32 is moved downward in FIG. As shown to a), the convex part 204 is engaged under the nail | claw part 206. FIG. By engaging the convex portion 204 under the claw portion 206, the packing 36 is deformed and the state where the hollow portion 30 and the hollow portion 34 are communicated is maintained as shown in FIG. By maintaining the state in which the hollow portion 30 and the hollow portion 34 communicate with each other, the cosmetics can be passed from the pipe 22 through the hollow portions 30 and 34 from the spout 24 even when the pressing member 38 is left unattended. As the spray continues, the pressure in the sealed can 14 is automatically released.

このようにして化粧品を密閉缶体14から抜くことにより、密閉缶体14内の圧力が減少して略大気圧と同じになる。圧力が略大気圧と同じになった状態でスプレー缶200を廃棄処分する。   By removing the cosmetic from the sealed can body 14 in this way, the pressure in the sealed can body 14 is reduced to be approximately the same as the atmospheric pressure. The spray can 200 is disposed of in a state where the pressure is substantially equal to the atmospheric pressure.

次に、本願発明に係るスプレー缶の圧抜き構造について説明する。Next, the pressure relief structure of the spray can according to the present invention will be described.

図3に示すように、本実施形態のスプレー缶の圧抜き構造360は、押圧部材38を囲むように密閉缶体14のかしめ突起部15にガード362を取り付け、このガード362に可撓連結部364を介して押圧部材38の一端側を連結することによって、押圧部材38の他端部に設けたレバー366を操作して押圧部材38を上下移動させるように構成されている。このレバー366の下部には、凸部368が設けられ、ガード362には凸部368を係止する係止突起370が設けられている。これら凸部368と係止突起370とが、規制手段及び開放維持手段を構成している。このスプレー缶の圧抜き構造360は、廃棄時には、レバー366を強く押し込むことによって、凸部368を係止突起370の下方に係合させる。このことで、押圧部材38の押圧状態が維持され、噴出経路16が開放されて化粧品が噴出する状態に維持できる。なお、廃棄時以外には、凸部368が係止突起370の上方に当たり、押圧部材38の押し下げ距離が規制される。 As shown in FIG. 3, the spray can depressurization structure 360 of the present embodiment has a guard 362 attached to the caulking protrusion 15 of the sealed can 14 so as to surround the pressing member 38, and a flexible connecting portion is attached to the guard 362. By connecting one end side of the pressing member 38 via 364, the lever 366 provided at the other end of the pressing member 38 is operated to move the pressing member 38 up and down . A convex portion 368 is provided at the lower portion of the lever 366, and a locking projection 370 for locking the convex portion 368 is provided on the guard 362. These convex portions 368 and the locking projections 370 constitute restriction means and open maintaining means. In the spray can pressure-removing structure 360, at the time of disposal, the lever 366 is pressed firmly to engage the convex portion 368 below the locking projection 370. By this, the pressing state of the pressing member 38 is maintained, and it can be maintained in the state where the ejection path 16 is opened and cosmetics are ejected. In addition, except at the time of disposal, the convex part 368 hits the upper part of the latching protrusion 370, and the pressing-down distance of the pressing member 38 is controlled.
