Definitions
- the present invention relates to a spray can which releases compressed cosmetics, paints, propane gas or the like and a pressure releasing structure of such spray can.
- FIG. 36 shows an example of a spray can 101 for cosmetics.
- the spray can 101 comprises a sealed can body 103 for holding a compressed cosmetic fluid 102 , a spout path 104 for leading the cosmetic fluid 102 to the outside, and an opening/closing means 105 for closing or opening the spout path 104 .
- the spout path 104 comprises a pipe 106 that leads to the cosmetic fluid 102 in the sealed can body 103 , a spout 107 that leads to the outside, and a connecting path 108 for connecting the pipe 106 and the spout 107 .
- the connecting path 108 is composed of a hollow part 110 of a pipe supporting member 109 for supporting the pipe 106 and a hollow part 112 of a movable member 111 that is inserted into the pipe supporting member 109 .
- the opening/closing means 105 is composed of a packing 113 that is a blockage between the hollow parts 110 and 112 and a pushing member 114 that releases the blockage by pushing down the movable member 111 . In this spray can 101 , the spout path 104 is closed by the packing 113 .
- the pushing member 114 is pushed down by a finger 115 and the packing 113 is deformed, so that the spout path 104 is opened and the cosmetic fluid spouts out to the outside, as shown in FIG. 38 .
- the pressure in the sealed can body has to be released and reduced substantially to the outside pressure by pushing down the pushing member 114 by a finger 115 and spouting out almost all the cosmetic fluid 102 so as to prevent an accidental explosion of gas left in the sealed can body.
- the pressure is released from the sealed can body 103 through a hole formed in the sealed can body.
- it requires hard effort to make such hole using a tool and/or extra cost is necessary when a special equipment is used.
- an object of the present invention is to release pressure from a spray can easily, quickly, and safely when the spray can is disposed of after use.
- a spray can of the present invention comprises a sealed can body for holding a compressed fluid, a spout path for leading the fluid in the sealed can body to the outside, an opening/closing means for closing or opening the spout path, and a pressure releasing structure for allowing the pressure to be released from the sealed can body to the outside.
- the aforementioned pressure releasing structure is an open-state maintaining means for maintaining the spout path in its open state.
- the aforementioned pressure releasing structure is a breaking means for breaking the spray can.
- the aforementioned breaking means is a means for breaking the spout path.
- the aforementioned spout path has a pipe that leads to the fluid in the sealed can body, a spout that leads to the outside, and a connecting path for connecting the pipe and the spout, and the aforementioned breaking means is a means for separating the connecting path.
- the aforementioned breaking means is a means for breaking the spout path by spring force applied to the spout path by pushing down the pushing member and comprises a restricting means for restricting the distance that the pushing member is pushed down.
- the aforementioned opening/closing means is a means for opening the spout path by pushing down the pushing member and the pushing member of the opening/closing means is the pushing member of the breaking means.
- the aforementioned breaking means is a means for breaking the sealed can body.
- the aforementioned pressure releasing structure is a release path forming means for releasing pressure from the sealed can body to the outside.
- the aforementioned opening/closing means is a means for opening the spout path by pushing down the pushing member and is capable of forming a release path that releases the compressed fluid to the outside by pushing Clown the pushing member.
- a pressure releasing structure of the present invention comprises a sealed can body for holding a compressed fluid, a spout path for leading the fluid in the sealed can body to the outside, and an opening/closing means for closing or opening the spout path and allows the pressure to be released from the sealed can body to the outside.
- the pressure releasing structure of the present invention is an open-state maintaining means for maintaining the spout path in its open state
- the pressure releasing structure of the present invention is a means for breaking the spray can.
- the pressure releasing structure of the present invention is a means for breaking the spout path.

- In
FIG. 1 , numeral 200 indicates a spray can of the present invention. The spray can 200 comprises a sealedcan body 14 for holding a compressed cosmetic fluid such as hair treatment, aspout path 16 for leading the cosmetic fluid in the sealed can body to the outside, an opening/closing means 18 for closing or opening thespout path 16, and an open-state maintaining means 202 for maintaining thespout path 16 in its open state. The open-state maintaining means 202 functions as a pressure releasing structure of the spray can. - The
spout path 16 has apipe 22 that leads to the cosmetic fluid in the sealed can body, aspout 24 that leads to the outside, and a connectingpath 26 for connecting thepipe 22 and thespout 24. The connectingpath 26 is composed of ahollow part 30 of apipe supporting member 28 for supporting thepipe 22 and ahollow part 34 of amovable member 32 that is inserted into thepipe supporting member 28. The opening/closing means 18 is composed of a packing 36 that is a blockage between thehollow parts member 38 that releases the blockage by pushing down themovable member 32. - The open-state maintaining means 202 is composed of two
projections 204 provided to the pushingmember 38 which is rotatable around themovable member 32 and twonails 206 provided to the sealed canbody 14. - In general use of this spray can 200 for cosmetics or the like, when the pushing
member 38 is pushed down, themovable member 32 is moved down, the packing 36 engaged with themovable member 32 is deformed, and therefore thehollow parts hollow parts spout 24 through thehollow parts body 14. - Next, there will be described the case where the spray can 200 is disposed of after use. When the pushing
member 38 is turned 90 degrees while the pushingmember 38 is being pushed down, the movable member is moved downward and thus theprojections 204 are engaged withnails 206 with theprojections 204 under thenails 206, as shown inFIG. 2 (a). When theprojections 204 are engaged with thenails 206, the packing 36 is deformed and thehollow parts FIG. 2 (b). Since the condition where thehollow parts member 38 is not pushed, the cosmetic fluid continuously spouts out from thespout 24 through thepipe 22 and thehollow parts body 14. - In this way, by draining the cosmetic fluid from the sealed can
body 14, the pressure in thecan body 14 decreases to the atmospheric pressure. When the pressure in the sealed canbody 14 becomes substantially the same as the atmospheric pressure, the spray can 200 can be disposed of. - While one embodiment of the present invention has thus been described, the spray can of the present invention can also be materialized in other embodiments.
- For example, the spray can of the present invention may be a spray can 210 shown in
FIG. 3 . This spray can 210 comprises a sealedcan body 14, aspout path 16, opening/closing means 18, and a breaking means 212 for breaking a part of thespout path 16. The breaking means 212 functions as a pressure releasing structure of the spray can. The braking means 212 comprises amovable member 32. By deeply pushing down themovable member 32, themovable member 32 breaks and separates thepipe supporting member 28. Around thepipe supporting member 28, anotch 42 of a V-shaped cross section is provided so as to easily separate thepipe supporting member 28. Further, on the top of the sealed canbody 14 is provided aring 216 having a recessedpart 214. Also, acap 218 is provided for covering the pushingmember 38. On the inner surface of thecap 218, aprojection 220 that is engaged with the recessedpart 214 and aprojection 222 that is fit into the recessedpart 214 are provided. - In general use of the spray can 210, when the pushing
member 38 is pushed down by afinger 48, themovable member 32 is moved down, the packing 36 engaged with themovable member 32 is deformed, and therefore thehollow parts FIG. 4 . When thehollow parts spout 24 through thehollow parts - Next, there will be described the case where the spray can 210 is disposed of after use. When the
cap 218 is pushed down hard by a finger, theprojection 222 is fitted into the recessedpart 214, as shown inFIG. 5 . Then, thecap 218 is pulled up by fingers, the pushingmember 38 and thering 216 are pulled out upwards, as shown inFIG. 6 . Next, the spray can 210 is turned upside down, and then the movable 32 is hit on the hard ground or the like. By doing this, themovable member 32 is pushed into the sealed can body more deeply than when it is generally used and hits against the inner surface of thepipe supporting member 28, and thepipe supporting member 28 is broken and separated at thenotch 42. As shown inFIG. 7 , the separated part is fallen down in the sealed canbody 14. When thepipe supporting member 28 is broken, the cosmetic fluid flows into thehollow part 30 by pressure in the sealed can body and spouts out to the outside. Since the cosmetic fluid spouts out not through thepipe 22, the cosmetic fluid spouts out more quickly without decrease in speed due to fluid friction in thepipe 22. When thepipe supporting member 28 is broken, themovable member 32 may be fallen into the sealed canbody 14. This enables the cosmetic fluid to spout out much more quickly. Furthermore, thepipe supporting member 28 may be broken by putting one's weight on the spray can 210 while themovable member 32 of the spray can 210 is turned upside down and pressed against the hard ground or the like. Further, thepipe supporting member 28 may be broken by hitting the pushingmember 38 itself on the hard ground or the like or by putting one's weight thereon. In this case, it is preferable that themovable member 32 is longer in length. - Further, in the spray can 210, the
ring 216 may be made of fragile material like wax so as to remove thering 216 after it is broken and to deeply press themovable member 32. Furthermore, thering 216 may be pulled upwards. - Alternatively, the spray can of the present invention may be a spray can 230 shown in
FIG. 8 . In this spray can 230, a lower part of thehollow part 30 is tapered. When thering 216 is removed and themovable member 32 is pushed down, themovable member 32 is forcibly inserted into thehollow part 30 and fixed so that the pressure can be released. In this case, the lower part of thehollow part 30 which is tapered functions as an open-state maintaining means (pressure releasing structure). - Alternatively, the spray can of the present invention may be a spray can 240 shown in
FIG. 9 . This spray can 240 comprises agroove pattern 242 on the bottom of the sealed canbody 14. Thegroove pattern 242 is composed of asmall circle groove 244, abig circle groove 246, andradial grooves 248.Such groove pattern 242 makes it possible to easily break the bottom of the sealed canbody 14 by hand or a tool so as to release the pressure when the spray can 240 is disposed of.FIG. 9 shows as an example that thegroove pattern 242 is formed on the inner surface of the bottom of the sealed canbody 14, however, thegroove pattern 242 may be formed on the outer surface of the bottom of the sealed canbody 14. Further,FIG. 9 shows as an example that thegroove pattern 242 is like a chrysanthemum pattern or a sectional pattern of an orange, however, it may be like a honeycomb pattern or a scale pattern. - Alternatively, the spray can of the present invention may be a
spray can 10 shown inFIG. 10 . The spray can 10 comprises a sealedcan body 14 for holding a compressed cosmetic fluid such as hair treatment, aspout path 16 for leading the cosmetic fluid in the sealed canbody 14 to the outside, an opening/closing means 18 for closing or opening thespout path 16, and a breaking means 20 for breaking a part of thespout path 16. The breaking means 20 is composed of amovable member 32 and aspring 40. When themovable member 32 is pushed down more deeply, thepipe supporting member 28 is separated and broken by the spring force of thespring 40. Around thepipe supporting member 28, there is provided anotch 42 of a V-shaped cross section so as to easily separate thepipe supporting member 28. In order to prevent thepipe supporting member 28 from being broken except when the spray can 10 is disposed of, a resin stopper 44 (restricting means) for restricting the distance that the pushingmember 38 is pushed down is separably fixed on the bottom of the pushingmember 38. - In general use of the
spray can 10, when the pushingmember 38 is pushed down by afinger 48, themovable member 32 is moved down, the packing 36 engaged with themovable member 32 is deformed, and therefore thehollow parts FIG. 11 . When thehollow parts spout 24 through thepipe 22 and thehollow parts body 14. - Next, there will be described the case where the spray can 10 is disposed of after use. First, the
stopper 44 is cut off along acutoff line 46 shown inFIG. 12 . Then, the pushingmember 38 is pushed down by afinger 48 to such a degree that it comes into contact with the sealed canbody 14. Themovable member 32 is moved more downward than when it is generally used as described above, and the spring force of thespring 40 becomes stronger than when it is generally used as described above. By increased spring force, thepipe supporting member 28 is broken and separated at thenotch 42, as shown inFIG. 13 . When thepipe supporting member 28 is broken, the cosmetic fluid flows into thehollow part 30 by pressure in the sealed canbody 14 and spouts out to the outside. Since the cosmetic fluid spouts out not though thepipe 22, the cosmetic fluid spouts out more quickly without decrease in speed due to fluid friction in thepipe 22. - Alternatively, the spray can of the present invention may be a
spray can 50 shown inFIG. 14 . In this spray can 50, amovable member 52 is longer than themovable member 32 of the spray can 10 shown inFIG. 10 . Therefore, when thestopper 44 is cut off and the pushingmember 38 is pushed down more deeply so as to dispose of thespray can 50, themovable member 52 is directly hit against the pipe supporting means 28, and thepipe supporting member 28 is separated, as shown inFIG. 15 . - Alternatively, the spray can of the present invention may be a
spray can 56 shown inFIG. 16 . This spray can 56 comprises aspout path 16 having a packing 58. When thestopper 44 is cut off and the pushingmember 38 is pushed down so as to dispose of thespray can 56, the packing 58 that is engaged with themovable member 32 is stretched and broken. - Alternatively, the spray can of the present invention may be a
spray can 60 shown inFIG. 17 . This spray can 60 comprises a sealedcan body 14, aspout path 16, an opening/closing means 18, and a release path forming means 62 for forming a release path that releases the cosmetic fluid to the outside. The release path forming means 62 functions as a pressure releasing structure of the spray can. As shown inFIG. 18 , the release path forming means 62 is composed of a recessedpart 66 provided on a part of the side wall of themovable member 64 and a packing 36. The pushingmember 38 has ahole 68 for releasing cosmetic fluid. When thestopper 44 is cut off and the pushingmember 38 is pushed down so as to dispose of thespray can 60, therelease path 70 is formed between the packing 36 and the recessedpart 66, so that the cosmetic fluid is released from thehole 68 through therelease path 70. - Alternatively, the spray can of the present invention may be a
spray can 72 shown inFIG. 20 . This spray can 72 has ahole 74 in the sealed canbody 14, and thehole 74 is closed by a closingmember 76. A beveled surface of thehole 74 and a beveled surface of the closingmember 76 are in contact with each other. The closingmember 76 is pressed by the inner pressure of the sealed canbody 14 and is brought in tight contact with thehole 74. When the spray can 72 is disposed of, the pushingmember 38 is removed and broken, and the closingmember 76 is pressed into the sealed canbody 14 so that the closingmember 76 falls into the sealed canbody 14. Thus, by opening thehole 74, the release path for releasing the pressure is formed. - Alternatively, the spray can of the present invention may be a spray can 300 shown in
FIG. 21 . In this spray can 300, the pushingmember 38 is rotatable to the sealed canbody 14 and comprises aprojection 302, and the sealed canbody 14 comprises anail 304. When this spray can 300 is placed on the market, theprojection 302 is engaged with thenail 304 with theprojection 302 on thenail 304, as shown in FIGS. 21(a) and 21(b), and therefore the pushingmember 38 cannot be pushed down and the cosmetic fluid cannot be released. In other words, theprojection 302 and thenail 304 function as a locking means for locking thespout path 16 so that thespout path 16 cannot be opened. Unless the pushingmember 38 is rotated to release the locking means, the cosmetic fluid cannot be released. Therefore, there is no need to provide a cap to the spray can. - The cosmetic fluid can be released by turning the pushing
member 38 about 90 degrees so as not to engage thenail 302 with theprojection 302, as shown inFIG. 21 (c), and then moving the pushingmember 38 downward. When the spray can 300 is disposed of, the pushingmember 38 is pushed downward, and then rotated about 90 degrees so that theprojection 302 can be engaged with thenail 304 with theprojection 302 under thenail 304. In this way, thespout path 16 can be maintained in its open state and the cosmetic fluid can be released. - Alternatively, another projection which can be cut out may be provided above the
projection 302. In this case, when the pushingmember 38 is pushed downward and rotated for disposal of the spray can, this another projection may be cut out so as to engage theprojection 302 with thenail 304 with theprojection 302 under thenail 304. This can prevent the pushingmember 38 from being pushed downward and rotated so as to engage theprojection 302 with thenail 304 and thus prevent the possibility that the pushingmember 38 cannot be put back to the upper position when the spray can is not disposed of. Alternatively, a coin groove for rotating the pushingmember 38 by coin may be provided on the top surface of the pushingmember 38. InFIG. 21 , thenail 304 is integrally formed with the sealed canbody 14, however, thenail 304 which is formed separately from the sealed canbody 14 may be forcibly inserted into the top of the sealed canbody 14. - Alternatively, as shown in
FIG. 22 , in apressure releasing structure 310, aprotrusion 318 may be provided to thespout 24 of the pushingmember 38 that is rotatable to the sealed canbody 14, and aguard 312 having aprojection 314 as a locking means and awindow 316 as an open-state maintaining means may be provided to a caulkedprojection 15 of the sealed canbody 14 in such a manner that theguard 312 surrounds the pushingmember 38. As the caulkedprojection 15, a conventional caulked projection of a sealed can body can be used, and theguard 312 is detachably/attachably provided to the caulkedprojection 15. Further, thewindow 316 is connected to the outside of theguard 312. - When the
pressure releasing structure 310 of this spray can is placed on the market, theprotrusion 318 is engaged with theprojection 314 with theprotrusion 318 on theprojection 314, as shown inFIG. 22 , and therefore the pushingmember 38 cannot be pushed down and the cosmetic fluid cannot be released. When the cosmetic fluid is released, the pushingmember 38 is rotated so as to disengage theprotrusion 318 from theprojection 314 and then pushed downward. When the spray can is disposed of, the pushingmember 38 is pushed downward and rotated so as to engageprotrusion 318 in thewindow 316. Thus, thespout path 16 can be maintained in its open state and the cosmetic fluid can be released. Preferably, a coin groove is provided on the top surface of the pushingmember 38 so that the pushingmember 38 can be rotated only by a coin. This is preferable for safety reasons because children cannot easily rotate the pushingmember 38. - The
pressure releasing structure 310 of this spray can can be applied to a conventional sealed can body having a caulked projection. Therefore, the pressure can be released from a conventional sealed can body using thispressure releasing structure 310, if the pushingmember 38 and theguard 312 are provided thereto. It is also possible that a sealed can body with cosmetics, paints, propane gas, or the like filled therein are placed on the market without attaching the pushingmember 38 and so on. In this case, a user can release the pressure from the sealed can body by attaching the pushingmember 38 andguard 312 on hand thereto. If the sealed can body is placed alone on the market, it is preferable to provide an elastic tube, cap, or the like to themovable member 32 of the sealed canbody 14 in advance so as to prevent accidental pushing of the pushingmember 38. - Alternatively, the spray can of the present invention may be a spray can 320 shown in
FIG. 23 . In this spray can 320, the pushingmember 38 comprises astopper 322 which can be cut out and which functions as a restricting means and a projectedpart 326 which can be engaged in the recessedpart 324 of the sealed canbody 14 and which functions as an open-state maintaining means. When this spray can 320 is disposed of, the pushingmember 38 is pushed into the sealed canbody 14 by hitting it or so to such a degree that thestopper 322 is cut out, as shown inFIG. 23 by chained lines, and thus the projectedpart 326 is engaged in the recessedpart 324. In this way, the pushingmember 38 is maintained in its pushed state and thespout path 16 is maintained in its open state, so that the cosmetic fluid can be released. When thestopper 322 is cut out by pushing the pushingmember 38 into the sealed canbody 14, it is preferable that the lower part of the pushingmember 38 is resiliently spread to engage the projectedpart 326 in the recessedpart 324. Since thestopper 322 restricts the pushing distance of the pushingmember 38, the projectedpart 326 is not engaged in the recessedpart 324 except when the spray can is disposed of. - Alternatively, in a
pressure releasing structure 330 of the spray can, the pushingmember 38 may comprise astopper 44 which can be cut out and which functions as a restricting means and a projectedpart 332 which can be engaged with the lower part of the caulkedprojection 15 of the sealed canbody 14 and which functions as an open-state maintaining means. When the spray can is disposed of, thestopper 44 which is provided on the lower part of the pushingstopper 38 is cut out and the pushingmeans 38 is pushed down, so that the projectedpart 332 is engaged with the lower part of the caulkedprojection 15, as shown inFIG. 24 by chained lines. In this way, the pushingmember 38 is maintained in its pushed state and thespout path 16 is maintained in its open state, so that the cosmetic fluid can be released. Since thestopper 44 restricts the pushing distance of the pushingmember 38, the projectedpart 332 is not engaged in the caulkedprojection 15 except when the spray can is disposed of. Thepressure releasing structure 330 of this spray can can be applied to a conventional sealed can body having a caulked projection. Therefore, the pressure can be released from a conventional sealed can body using thispressure releasing structure 330, if the pushingmember 38 is provided thereto. - Alternatively, as shown in
FIG. 25 , in thepressure releasing structure 340 of the spray can, theguard 324 may be provided on the caulkedprojection 15 of the sealed canbody 14 in such a manner that the pushingmember 38 is sandwiched in theguard 324, a pair ofupper grooves 344 and a pair of lower grooves 346 (open-state maintaining means) may be provided in the inner surface of theguard 342 which is opposed to the pushingmember 38, and aplate 348 may be attachably/detachably inserted between theupper grooves 344 or between thelower grooves 346. When thispressure releasing structure 340 of the spray can is placed on the market, theplate 348 is put in theupper grooves 344 to cover the pushingmember 38, as shown inFIG. 25 , so that the pushingmember 38 cannot be pushed down and the cosmetic fluid cannot be released. - When the cosmetic fluid is released, the
plate 348 is pulling out from theupper grooves 344 to the rear and then the pushingmember 38 is pushed down. When the spray can is disposed of, the pushingmember 38 is pushed downward, and then theplate 348 is put in between thelower grooves 346 to fix the pushingmember 38 under theplate 348. In this way, thespout path 16 can be maintained in its open state so that the cosmetic fluid can be released. Thepressure releasing structure 340 of this spray can can be applied to a conventional sealed can body having a caulked projection. Therefore, the pressure can be released from a conventional sealed can body using thispressure releasing structure 340, if theguard 342 and theplate 348 are provided thereto. - The direction the
upper grooves 344 and thelower grooves 346 are formed and the direction the plated 348 is put in are not limited to the direction perpendicular to the moving direction of the pushingmember 38. As far as the pushing member can be maintained in its pushed state, such directions may be the direction parallel to the moving direction of the pushingmember 38 or the direction oblique thereto. Alternatively, instead of removably inserting theplate 348 into a pair ofupper grooves 344 or a pair oflower grooves 346, a pair of upper holes and a pair of lower holes (open-state maintaining means) may be formed in the inner surface of theguard 342 which is opposed to the pushingmember 38, and a pin material may be removably inserted into the upper holes or lower holes.FIG. 25 shows as an example that theguard 342 is fit over the caulkedprojection 15 from above the sealed canbody 14. However, theguard 342 may be fit inside the caulkedprojection 15 of the sealed canbody 14 or fit outside the caulkedprojection 15 from the side of the sealed canbody 14. Also, a nail directed towards the outside may be provided at the top of the sealed canbody 14 to removably engage theguard 342 with the nail or theguard 342 may be screwed into the top of the sealed canbody 14. - Alternatively, as shown in
FIG. 26 , in thepressure releasing structure 350 of the spray can, theguard 352 may be provided to the caulkedprojection 15 of the sealed canbody 14 in such a manner that the pushingmember 38 is enclosed by theguard 352. In this case, the pushingmember 38 may be moved up and down by engaging ashaft 356 provided to the one end of the pushingmember 38 with abearing 354 provided to theguard 352 and operating alever 357 provided to the other end of the pushingmember 38. As an open-state maintaining means, a pair ofbendable plates 358 is provided to the upper part of theguard 352. When the spray can is disposed of, the pushingmember 38 of thispressure releasing structure 350 is pushed downward, and then thebendable plates 358 are bent towards the pushingmember 38's side, as shown inFIG. 26 (b) by chained lines, so as to engage the pushingmember 38 with the lower part of thebendable plates 358. By doing this, the pushingmember 38 is maintained in its pushed state and thespout path 16 is opened so that the cosmetic fluid can be released. - Alternatively, as shown in
FIG. 27 , in thepressure releasing structure 360 of the spray can, theguard 362 may be provided to the caulkedprojection 15 of the sealed canbody 14 in such a manner that the pushingmember 38 is enclosed by theguard 362. In this case, the pushingmember 38 may be moved up and down by connecting the one end of the pushingmember 38 to theguard 362 through a flexible joint 364 and operating alever 366 provided to the other end of the pushingmember 38. On the lower part of thelever 366, aprojection 368 is provided. A protrudingblock 370 for preventing theprojection 368 from moving down is provided to theguard 362.Such projection 368 and theprotruding block 370 function as a restricting means as well as an open-state maintaining means. In thispressure releasing structure 360, when the spray can is disposed of, by pressing thelever 366, theprojection 368 is pushed down under the protrudingblock 370 and thus engaged with the protrudingblock 370. In this way, the pushingmember 38 is maintained in its pushed state and thespout path 16 is opened so that the cosmetic fluid can be released. Except when the spray can is disposed of, the protrudingblock 370 prevents theprojection 368 from moving down, and thus the pushing distance of the pushingmember 38 is restricted by the protrudingblock 370. - The pressure releasing structure of the spray can according to the present invention may be a
pressure releasing structure 400 shown inFIG. 28 . Thispressure releasing structure 400 is composed of acap 402 which is attachably/detachably attached to the inside of the caulkedprojection 15 of the sealed canbody 14. On the outer surface of thecap 402 is provided anupper projection 404 which can be engaged with the caulkedprojection 15 as an open-state maintaining means, and on the lower part of thecap 402 is provided astopper 44 which can be cut out along acutoff line 46. Further, on the outer surface of thestopper 44 is provided alower projection 406 which can be engaged with the caulkedprojection 15 with thelower projection 406 under the caulkedprojection 15. Furthermore, on the inner side of the top of thecap 402 is provided apush projection 408 with a V-shaped groove in its end, and on the side of thecap 402 is provided anopening 410. - When this
pressure releasing structure 400 is placed on the market, thelower projection 406 of thestopper 44 is engaged with the caulkedprojection 15 with thelower projection 406 under the caulkedprojection 15, as shown inFIG. 28 , and thecap 402 is attached to the sealed canbody 14. When the spray can is disposed of, thestopper 44 provided on the lower part of thecap 402 is cut out, themovable member 32 is pushed down using thepush projection 408, and thus thecap 402 is pushed down under the caulkedprojection 15 so that theupper projection 404 is engaged with the caulkedprojection 15. In this way, themovable member 32 is maintained in its pushed state, and thespout path 16 is opened so that the cosmetic fluid can spout out.FIG. 28 shows as an example that the sealed canbody 14 is a gas cylinder for a portable gas burner, however, thepressure releasing structure 400 can be applied to the spray can having a pushing member attached to the upper part of the movable member. Further, thepush projection 408 on the inner surface of the top of thecap 402 is not always needed, but themovable member 32 may be directly pushed down by the top of thecap 402. Furthermore, the upper projection and the lower projection may be provided on the inner surface of thecap 402 and thecap 402 may be attachably/detachably attached to the outside of the caulkedprojection 15. - The
pressure releasing structure 400 of this spray can can be applied to a conventional sealed can body having a caulked projection. Therefore, the pressure can be released from a conventional sealed can body using thispressure releasing structure 400, if thecap 402 is provided thereto. It is also possible that a sealedcan body 14 with cosmetics, paints, propane gas, or the like filled therein is placed on the market without attaching the pushing member and so on. In this case, a user can release the pressure from the sealed can body by attaching thecap 402 on hand thereto. If the sealed can body is placed alone on the market, it is preferable to provide an elastic tube, cap, or the like to themovable member 32 of the sealed canbody 14 in advance so as to prevent accidental pushing of themovable member 32. - Alternatively, as shown in
FIG. 29 , in thepressure releasing structure 420 of the spray can, ascrew member 424 may be screwed into the top of thecap 422 as an open-state maintaining means in such a manner that thescrew member 424 can be screwed up and down. Thescrew member 424 is screwed up and down in thecap 422 by inserting a coin or the like into agroove 426 formed in the top surface of thescrew member 424 and rotating thescrew member 424 using the coin or the like. On the lower part of thecap 422 is provided aprotrusion 428 which can be engaged with the caulkedprojection 15, and on the side of thecap 422 is provided anopening 430. - When this
pressure releasing structure 420 is placed on the market, theprotrusion 428 is engaged with the caulkedprojection 15 with theprotrusion 428 under the caulkedprojection 15, as shown inFIG. 29 , and thecap 422 is attached to the sealed canbody 14. When the spray can is disposed of, thescrew member 424 is screwed down so as to push down themovable member 32 with thecap 422 attached to the sealed canbody 14. In this way, themovable member 32 is maintained in its pushed state, and thespout path 16 is opened so that the cosmetic fluid can spout out. Thepressure releasing structure 420 of this spray can can be applied to a conventional sealed can body having a caulked projection. Therefore, the pressure can be released from a conventional sealed can body using thispressure releasing structure 420, if thecap 422 is provided thereto. Since thescrew member 424 can be screwed down to an arbitrary position, thepressure releasing structure 420 can be widely applied to various sealed can body having a movable member of different length. It is preferable for safety reasons that thescrew member 424 is rotated only by a coin so that children cannot easily rotate thescrew member 424.FIG. 29 also shows as an example that the sealed canbody 14 is a gas cylinder for a portable gas burner, however, thepressure releasing structure 420 can be applied to the spray can having a pushing member attached to the upper part of themovable member 32. When thepressure releasing structure 420 is applied to the spray can with a pushing member attached thereto, a cut may be formed in the lower part of thecap 422 and themovable member 32 may be inserted into the cut, so that the pushing member is pulled out by using thecap 422 as leverage. - Alternatively, as shown in
FIG. 30 , in thepressure releasing structure 440 of the spray can, apush member 444 may be fit into the top of thecap 442 as an open-state maintaining means in such a manner that thepush member 444 can be moved up and down. In this case, in the top of thecap 442 are provided anupper groove 446 and alower groove 448, and on the side of thepush member 444 is provided aprojection 450 which can be engaged in theupper groove 446 or thelower groove 448. Further, on the lower part of thecap 442 is provided aprotrusion 452 which can be engaged with the caulkedprojection 15, and on the side of thecap 442 is provided anopening 454. - When this
pressure releasing structure 440 is placed on the market, theprojection 450 of thepush member 444 is engaged in theupper groove 446 and theprotrusion 452 is engaged with the caulkedprojection 15 with theprotrusion 452 under the caulkedprojection 15, as shown inFIG. 30 , and thus thecap 442 is attached to the sealed canbody 14. When the spray can is disposed of, thepush member 444 is forcibly pressed downward with thecap 442 attached to the sealed canbody 14, themovable member 32 is pushed down, and thus theprojection 450 is engaged in thelower groove 448. In this way, themovable member 32 is maintained in its pushed state, and thespout path 16 is opened so that the cosmetic fluid can spout out. Thepressure releasing structure 440 of this spray can can also be applied to a conventional sealed can body having a caulked projection. Therefore, the pressure can be released from a conventional sealed can body using thispressure releasing structure 440, if thecap 442 is provided thereto.FIG. 30 shows as an example that thecap 442 is fit inside the caulkedprojection 15 from above the sealed canbody 14. However, thecap 442 may be fit outside the caulkedprojection 15 of the sealed canbody 14 or fit outside the caulkedprojection 15 from the side of the sealed canbody 14. - Alternatively, as shown in
FIG. 31 , in thepressure releasing structure 460 of the spray can, abendable plate 464 may be provided to the top of thecap 462 as an open-state maintaining means. Both sides of thebendable plate 464 is separated form the top of thecap 462, a front edge of thebendable plate 464 is connected to the top of thecap 462 through abreak part 466, and a rear edge of thebendable plate 464 is bendably connected to the top of thecap 462. Further, on the lower part of thecap 462 is provided aprotrusion 468 which can be engaged with the caulkedprojection 15, and on the side of thecap 442 is provided anopening 469. - When this
pressure releasing structure 460 is placed on the market, theprotrusion 468 is engaged with the caulkedprojection 15 with theprotrusion 468 under the caulkedprojection 15, as shown inFIG. 31 , and thecap 462 is attached to the sealed canbody 14. When the spray can is disposed of, thecap 462 is removed and the front edge of thebendable plate 464 is forcibly pressed to break thebreak part 464, and then thebendable plate 464 is bent inside thecap 462 as shown by chained lines. Then, while themovable member 32 is being pushed downward by using thebendable plate 464, thecap 462 is pressed inside the caulkedprojection 15 so as to engage theprotrusion 468 with the caulkedprojection 15 with theprotrusion 468 under the caulkedprojection 15. In this way, themovable member 32 is maintained in its pushed state, and thespout path 16 is opened so that the cosmetic fluid can spout out. - Alternatively, as shown in
FIG. 32 , in thepressure releasing structure 470 of the spray can, apush member 476 having ainclined surface 474 may be provided to the top of thecap 472 as an open-state maintaining means. Further, on the lower part of thecap 472 is provided aprotrusion 478 which can be fit to the caulkedprojection 15 with theprotrusion 478 under the caulkedprojection 15. One end of thecap 472 is notched. While theprotrusion 478 is being fit to the caulkedprojection 15, thecap 472 can be engaged with the caulkedprojection 15 by sliding it from the side of the sealed canbody 14. When thispressure releasing structure 470 is disposed of, thecap 472 is engaged with the caulkedprojection 15 by sliding it from the side of the sealed canbody 14, and then themovable member 32 is pushed downward by using theinclined surface 474 of thepush member 476. In this way, themovable member 32 is maintained in its pushed state, and thespout path 16 is opened so that the cosmetic fluid can spout out. - Alternatively, as shown in
FIG. 33 , in thepressure releasing structure 480 of the spray can, abendable plate 484 may be provided on a part of the side wall of thecap 482 as an open-state maintaining means. Both sides of thisbendable plate 484 are separated from the side wall of thecap 482, and the top part of thebendable plate 484 is bendably connected to the side wall of thecap 482. Further, on the lower part of thecap 482 is provided aprotrusion 486 which can be engaged with the caulkedprojection 15 with theprotrusion 486 under the caulkedprojection 15. - When this
pressure releasing structure 480 is placed on the market, theprotrusion 486 is engaged with the caulkedprojection 15 with theprotrusion 486 under the caulkedprojection 15, as shown inFIG. 33 , and thus thecap 482 is attached to the sealed canbody 14. When the spray can is disposed of, thecap 482 is removed, the lower part of thebendable plate 484 is pressed so as to bend it inside thecap 482 as shown by chained lines, and then the lower part of thebendable plate 484 is abutted against the inner surface of the opposite side wall of thecap 482. Then, while themovable member 32 is being pushed downward by using thebendable plate 484, thecap 482 is pressed inside the caulkedprojection 15 so as to engage theprotrusion 468 with the caulkedprojection 15 with theprotrusion 468 under the caulkedprojection 15. In this way, themovable member 32 is maintained in its pushed state, and thespout path 16 is opened so that the cosmetic fluid can spout out. When thebendable plate 484 is bent inside thecap 482, an opening is formed in a part of the side wall of thecap 482. Through this opening, the cosmetic fluid or the like can be released to the outside. In some cases, a protrusion may be provided on the opposite inner side surface of thecap 482 so as to support the lower end of the bentbendable plate 484. - Alternatively, the spray can of the present invention may be a spray can 500 shown in
FIG. 34 . This spray can comprises a sealedcan body 14, aspout path 16, an opening/closing means 18, and a breaking means 502 for breaking a part of thespout path 16. This breaking means 502 functions as a pressure releasing structure of the spray can. The breaking means 502 comprises amovable member 32. By deeply pushing down themovable member 32, themovable member 32 breaks and separates thepipe supporting member 28. Around thepipe supporting member 28, anotch 42 of a V-shaped cross section is provided so as to easily separate thepipe supporting member 28. Further, on the top of themovable member 32, a pushingmember 504 is attachably/detachably attached. Around the pushingmember 504, aprojection 506 is provided as a restricting means. - In general use of this spray can 500, when the pushing
member 504 is pushed down, themovable member 32 is moved down, so that the cosmetic fluid can be released. When the pushingmember 504 is pushed downward, theprojection 506 is struck by the caulkedprojection 15, so that the distance that themovable member 32 is pushed down can be restricted to a predetermined distance. When the spray can is disposed of, the pushingmember 504 is removed from themovable member 32. Then, the sealed canbody 14 is turned upside down, and then themovable member 32 is hit on the hard ground or the like. Themovable member 32 is hit against the inner surface of thepipe supporting member 28 and thepipe supporting member 28 is broken at thenotch 42. Thus, the cosmetic fluid is released through the broken part and ahollow part 30 to the outside by the pressure in the sealed canbody 14. - In order to easily remove the pushing
member 504 from themovable member 32, it is preferable that a lever piece for prying the pushingmember 504 away from the sealed canbody 14 is inserted between the pushingmember 504 and the sealed canbody 14. This lever piece may be attachably/detachably attached to the pushingmember 504. It is also possible that a sealedcan body 14 with cosmetics, paints, propane gas, or the like filled therein is placed on the market without attaching the pushingmember 504. In this case, a user can release the pressure from the sealed can body by attaching the pushingmember 504 on hand thereto. If the sealed can body is placed alone on the market, it is preferable to provide an elastic tube, cap, or the like to themovable member 32 of the sealed canbody 14 in advance so as to prevent accidental breaking of thepipe supporting member 28. - Alternatively, the spray can of the present invention may be a spray can 600 shown in FIGS. 35(a) and 35(b). This spray can 600 comprises a sealed
can body 14, aspout path 16, an opening/closing means 18, a breaking means 602 for breaking a part of thespout path 16, aguard 604 which is attached to a caulkedprojection 15 of the sealed canbody 14, and alever piece 606 which is attachably/detachably attached to theguard 604. The braking means 602 comprises amovable member 32. By deeply pushing down themovable member 32, themovable member 32 breaks and separates thepipe supporting member 28. Around thepipe supporting member 28, anotch 42 of a V-shaped cross section is provided so as to easily separate thepipe supporting member 28. Further, on top of themovable member 32, a pushingmember 38 is provided. - On the top of the
guard 604 is provided a pair ofgrooves 608. Eachgroove 608 has a pair ofprotrusions 610 on its both sides. Thelever piece 606 is attachably/detachably attached in thegrooves 608 by theprotrusions 610. Between one side of theguard 604 and the caulkedprojection 15 of the sealed canbody 14 is formed aside groove 614 which serves as aninsertion hole 612. By inserting thelever piece 606 into theinsertion hole 612, thelever piece 606 is attachably/detachably engaged at one side of theguard 604. An edge of thelever piece 606 is thin and aU-shaped cut 616 which can be inserted into themovable member 32 is made in the edge of thelever piece 606, as shown inFIG. 35 (b). - When the spray can 600 is placed on the market, the
lever piece 606 is attached in thegrooves 608 and covers the pushingmember 38, as shown in FIGS. 35(a) and 35(b), so that the pushingmember 38 cannot be pushed down and the cosmetic fluid cannot be released. When the cosmetic fluid is released, thelever piece 606 is removed from thegrooves 608 and then the pushingmember 38 is pushed down. Thelever piece 606 removed from thegrooves 608 is inserted into theinsertion hole 612 and is engaged at the side of theguard 604. When the spray can is disposed of, theguard 604 is pried away from the sealed canbody 14 by using thelever piece 606, theU-shaped cut 616 of thelever piece 606 is inserted into themovable member 32, and thus the pushingmember 38 is pried away form themovable member 32 by applying the principle of leverage. After that, the sealed canbody 14 is turned upside down, the exposedmovable member 32 is pressed against the ground or the like by putting one's weight on the sealed canbody 14, and thus thepipe supporting member 28 is broken by thenotch 42. In this way, the cosmetic fluid is released to the outside through the broken part and ahollow part 30 by the pressure in the sealed canbody 14. - The present invention is intended to embrace various modifications, alternations, and changes made on the basis of knowledge of those skilled in the art without departing from the scope of the invention. Further, any of the specific inventive aspects of the present invention may be replaced with other technical equivalents for embodiment of the present invention, as long as the effects and advantages intended by the invention can be insured. For example, the structure for pushing down the movable member in two stages is not limited to the structures shown in
FIGS. 3, 10 , 23, and 27, but it may be a structure in which a through hole is formed in the pushing member from its top to the movable member and the movable member is pressed by putting the finger in the through hole if the movable member is required to be more deeply pressed down. Further, the sealed can body is not limited to a cosmetic case or a gas cylinder. Furthermore, the shapes of the pushing member, the guard, and the cap are not limited to the aforementioned embodiments, but the shape of the pushing member, for example, may be shaped like a bear's head or shaped like an animal or a plant. Further, in the aforementioned embodiments, the spray can has a structure in which the packing 36 which is a blockage between thehollow part 30 of thepipe supporting member 38 and thehollow part 34 of themovable member 32 is bent and deformed by pushing down themovable member 32 against the spring force so that thehollow parts - As described above, in the spray can having the open-state maintaining means and the pressure releasing structure of the spray can according to the present invention, the spray path can be maintained in its open state. Therefore, when the spray can is disposed of, pressure can be released by maintaining the spout path in its open state.
- In the spray can having the breaking means and the pressure releasing structure of the spray can according to the present invention, a path for releasing the fluid in the sealed can body to the outside can be formed separately, so that a fluid friction or the like can be reduced when the fluid is released. Therefore, when the spray can is disposed of, the fluid spouts out to the outside more quickly and easily.
- Further, in the spray can and the pressure releasing structure according to the present invention in which the breaking means functions as means for separating the connecting path, the spout path can be always broken at the same position without fail. Therefore, there are not cases where a path for spouting out the fluid to the outside cannot be formed due to insufficient breaking force or where the size of the path is not large enough to reduce fluid friction or the like.
- Furthermore, in the spray can having the restricting means for restricting the distance that the pushing member is pushed and the pressure releasing structure of the spray can according to the present invention, the restricting means prevents breaking of the spout path by restricting the movement of the pushing member in normal use while the restricting means cancels such restriction so that the spout path can be broken when the spray can is disposed of.
- Further, in the spray can in which the pushing member of the opening/closing means is the pushing member of the breaking means and the pressure releasing structure of the present invention according to the present invention, the pushing member of the opening/closing means also serves as the pushing member for breaking the spout path. For this reason, the spray can is made more compact and the production cost can be reduced.
- In the spray can having the release path forming means and the pressure releasing structure of the spray can according to the present invention, the fluid can be quickly and easily released to the outside, for example, through a release path which is directly connected to the outside of the sealed can body.
- Further, in the spray can having the locking means and the pressure releasing structure of the spray can according to the present invention, since the cosmetic fluid cannot be released unless the locking means is disengaged, there is no need to provide a cap to the spray can. Therefore, the spray can is made more compact and the production cost can be reduced.
