  • spraying gas at the top of this container 1 is provided a cylinder-like nozzle 11 having a nozzle hole 12.
  • the nozzle 11 in this embodiment is designed in such a way that the spray liquid is injected from the nozzle hole 12 when the nozzle 11 is pressed downward and that the nozzle 11 is pushed up by the thrusting means provided on the nozzle 11 to stop the sending out of spray liquid when the pressing down is stopped, but this nozzle 11 may also be realized as tilt type which injects the spray liquid when the nozzle is tilted by pressing.
  • the control member 2 comprises a body unit 10, an operating unit provided in this body unit 10, a regulator mechanism unit, and a spraying member 70 having a spray hole 7.

  • This nozzle fitting hole 3 is provided with a nozzle top end face contact part 31 by forming a stepped part at the top of which the top edge of the nozzle 11 can get in contact.
  • This nozzle top end face contact part 31 is realized in such a way that only the top part of the nozzle 11 fits so that the top end face of the nozzle may be in contact with this part, and this nozzle top end face contact part 31 can be operated to push down the nozzle with pressing down of the control member 2.
  • the regulator mechanism unit is realized by comprising, inside a roughly cylindrical space (4) formed at the center of the control member 2, a sliding member 5 disposed in a way to slide in the axial direction (vertical direction in the drawing) of the nozzle 11 and a thrusting means 6 for constantly thrusting this sliding member 5 to the nozzle 11 (downward direction in the drawing) side.
  • the sliding member 5 consists of a cylindrical member having a bottom 51 at the upper part, and this bottom part 51 serves as partition wall.
  • the sliding member 5 also has a protrusion 54 extending downward, from the center of its bottom part 51 and a shielding part formed at the tip of this protrusion 54.
  • a nozzle opening 41 Above the nozzle top end face contact part 31 provided inside the bottom center of the body unit 10 is formed a nozzle opening 41, and below the bottom part 51 of the sliding member 5 is formed a reservoir or pool 44, and a connecting hole 43 is provided for communication between those nozzle opening 41 and pool 44.
  • the connecting hole 43 is formed, on the nozzle opening 41, by keeping the inside diameter of the partition of the body unit 10 smaller than the inside diameter of the nozzle opening 41. This makes it possible to form a stepped part at the border with the nozzle opening 41.
  • This cylindrical periphery 53 serves as the sliding face of the sliding member 5.
  • a reservoir or pool 45 is formed in the shape of a ring also between the bottom end of the cylindrical periphery 53 of the sliding member 5 and the inner wall of the body unit 10.
  • the sealing member 51a tightly seals between the sliding member 5 and the partition of the body unit 10
  • the pools 44, 45 formed between the sliding member 5 and the inner wall of the body unit 10 are completely separated from the thrusting means housing 42, and can temporarily store the spray liquid released at proper pressure from the nozzle hole 11 of the container 1 without allowing the spray liquid inside the container 1 flowing into the pools 44, 45 to pass into the thrusting means housing 42.
  • between those pools 44, 45 and also between this pool 45 and the injection member 70 is provided a passage communicating between them respectively.
  • those passages are intended to not only hold the spray liquid and gas in the pools 44, 45 to raise the internal pressure in the pools 44, 45 to the prescribed pressure but also send the spray liquid flowing into the pools 44, 45 to the spraying member 70 at that prescribed internal pressure.
  • those communicating passages are realized in a way to form a narrow clearance between the sliding member 5 and inner wall of the body unit 10 to demonstrate said effects.
  • the passage communicating from the pool 45 to the spraying member 70 passes through the communicating hole 73.
  • the protrusion 54 is a round bar, the shaft diameter of which is formed smaller than said connecting hole 43 formed between the nozzle opening 41 and the pool 44, and its front end side extends to the inside of the nozzle opening 41 passing through the connecting hole 43.
  • the shielding part 52 at the front end of the protrusion 54 is disposed in the nozzle opening 41, and is composed of a flange 52a and a shielding member 52b.
  • the flange 52a has an upper outer diameter larger than the diameter of the connecting hole 43 but smaller than the diameter of the nozzle opening 41, while its lower surface is formed as a flat plane, disposed in such a way that the entire bottom surface is orthogonal to the axial direction of the nozzle 11, and is formed so that the spray liquid and gas inside the container 1 sent out from the nozzle hole 12 may hit against this bottom face.
  • the shielding member 52b is made of an elastic O ring for sealing, and extends around the protrusion 54 in the upper part of the flange 52a.
  • the outer diameter of this shielding member 52b is larger than the diameter of the connecting hole 43 in the state wound around the protrusion 54, and can therefore seal the connecting hole 43.
  • a cylindrical coil spring is used in this embodiment and disposed in the thrusting means housing 42 by being set between the bottom part 51 and the top lid 8 in such a way that the lower end gets in touch with the top face of the bottom part 51 and the upper end gets in contact with the lower face of the top lid 8 respectively.
  • the sealing member 51a may be disposed, during said period of non use, not at a position closing the communicating hole 73 but at a position opening the communicating hole 73, i.e. a position slightly above the communicating hole 73.
  • the spray hole 7 is provided, in this embodiment, on the spraying member 70 which consists of a material separated from the body unit 10, and this spraying member 70 is attached to the portion of communicating hole 73 of the body unit 10 of the control member 2.
  • This spraying member 70 is formed with a spraying unit body 75 composed of bottomed cylindrical material having a spraying hole 7 on the left side in the drawing and a injection chip 74 composed of a cylindrical material disposed inside this spraying unit body 75.
  • This injection chip 74 has a small reservoir 76 provided at the center and a leading path 71 formed on its outer circumference.
  • This leading path 71 is formed, as described in detail later, with a narrow gap formed by a plural number of grooves made on the inner circumferential face of the spraying unit body 75 and on the outer circumferential face of the injection chip 74.
  • the spraying hole 7 which is a tiny hole, atomizes the spray liquid pushed out from the leading path 71. And, as this spraying member 70 is engaged with the spraying member fitting hole 2a provided on the outer wall of the control member 2, communication is established between the communicating hole 73 of the body unit 10 and the leading path 71 and, because the leading path 71 is formed narrow and the spray hole 7 is formed small, the sending out of the spray liquid and the gas sent into the reservoir 76 is restricted during the period until they are sprayed from the spray hole 7 by passing through the communicating hole 73, thus playing a function similar to that of said communicating passage in the regulator mechanism unit.
  • the nozzle 11 of the container 1 is engaged in the nozzle fitting hole 3 of the control member 2, and the control member 2 is attached to the container 1.
  • the sliding member 5 is thrust downward by the cylindrical coil spring 6 as shown in Fig. 1, the sealing member 51a of the cylindrical outer circumference 53 of the sliding member 5 is in the state of blocking the comminicating hole 73, and the shielding unit 52 is positioned about at the center of the nozzle opening 41, thereby keeping open the connecting hole 43.
  • the injected spray liquid hits against the bottom face of the shielding unit 52 to exert an upward pressure W3 on it and also flows into the pool 44 by passing through the open connecting hole 43 from the gap between the outer circumference of the shielding unit 52 and the inner circumference of the nozzle opening 41.
  • the communicating hole 73 opens and the spray liquid is sent into the reservoir 76 of the injection chip 74.
  • the internal pressure of this reservoir 76 also rises and the spray liquid starts to be injected outside from the spray hole 7 by passing through the leading path 71.
  • the sliding member 5 As this state of spraying is maintained and the internal pressure of pools 44, 45 and the reservoir 76 gets higher than the prescribed pressure, i.e. larger than the thrusting pressure W1 of the cylindrical coil spring 6 serving as thrusting means, the sliding member 5 further goes up. As the sliding member 5 is pushed up, the flange 52a of the shielding unit 52 closes the connecting hole 43 by blocking from below as shown in Fig. 3. Therefore, in the pools 44, 45 and reservoir 76, the internal pressure W2 does not go up any more and the spray liquid is sprayed from the spray hole 7 at that internal pressure W2.
  • the internal pressure W2 in the pools 44, 45 and reservoir 76 starts decreasing gradually and said sum of pressures W2 + W3 becomes smaller than the thrusting pressure W1 of the cylindrical coil spring 6. This makes the sliding member 5 move downward. If the sliding member comes down, the feed of the spray liquid and vaporized gas to the spraying member 70 is restricted and the connecting hole 43 gets in open state again. And, again, the spray liquid flows into the pools 44, 45 and reservoir 76, the total pressure W2 + W3 goes up and the spray liquid in the pools 44, 5 is sent into the spraying member 70 through the communicating hole 73, .e. the spray liquid is also sent into the reservoir 76 of the spraying member 70 to promote the injection for continuing spraying at prescribed pressure.
  • the spray liquid is sprayed in the form of mist from the spray hole 7 always at the internal pressure W2.
  • the spray liquid can be sent out always at a constant pressure from the beginning to the end of use and can maintain constant spraying state and state of atomization. Moreover, by using various cylindrical coil springs 6 of different thrusting forces, it becomes possible to adjust to any desired pressure easily as required.
  • cylindrical coil spring 6 is used as thrusting means, but other thrusting means may also be used as required.
  • the position for disposing the cylindrical coil spring 6 is not limited to the top face of the bottom part 51 of the sliding member 5 but may be changed as required by such methods as disposing the cylindrical coil spring 6, in the nozzle opening, between the top face of the shielding unit 52 and the stepped part of the connecting hole 43, or providing thrusting means capable of lowering the bottom part 51 in the portion of the pool 44, i.e. between the bottom face of the bottom part 51 of the sliding member and the inner wall of the body unit 10, etc., for example.
  • Fig. 4 indicates the sealing member 51a used for the spray mechanism of said embodiment of the present invention, (A) being a plan view and (B) being an S-S end view thereof.
  • This sealing member 51a is a ring-shaped packing made of flexible and richly elastic synthetic rubber, elastomer or synthetic resin, etc.
  • This sectional shape is shaped, as it is apparent from the end face drawing in Fig. 4 (B), in the form of reversed character V or reversed character U, has 2 legs 51b below and also has a space 51c between the legs.
  • this sealing member 51a it becomes possible to improve the tightness between the sliding member and the inner wall of the space 4, and to better prevent leakage of spray liquid (called “after-draw”) from the spray hole when stopping the injection by stopping the pressing of the control member 2.
  • Fig. 5 indicates the injection chip 74 disposed in the spraying member 70 used for said embodiment, (A) being a plan view, (B) a sectional view of the line A'-A-O-B in the previous drawing and (C) a bottom view.
  • this injection chip 74 As it is seen from the sectional view, at the center of this injection chip 74 is formed a reservoir 76 composed of an about cylindrical hole for storing the spray liquid, and groove 76a is formed about radially in 4 directions from the opening of this reservoir 76 (see Fig. 5 (C)). And from this groove 76a is provided groove 76b in the axial direction on the outer circumferential face of the injection chip 74 continuously from this groove 76a, and groove 76c is further provided toward the concavity 76d provided at the center on the top of the injection chip 74 from this groove 76b (see Fig. 5 (A)).
  • the spray liquid sent from the communicating hole 73 of the body unit 10 of the control member 2 first stays in the reservoir 76 of the injection chip 74 and then passes from the opening of the reservoir 76 through the groove 76a formed about radially, passes through the groove 76b provided on the outer circumferential face of the injection chip 74 and further passes through the groove 76c formed on the end face of the spray hole 7 of the injection chip 74 to reach the concavity 76c at its center and be injected to outside from the spray hole 7 of the spraying member 70.
  • Those grooves 76a, 76b, 76c form the leading path 71 (see Fig. 1 to Fig. 3). Because those grooves 76a, 76b, 76c are very narrow passages, the internal pressure of the pools 44, 45 in the control member 2 and the reservoir 76 in the injection chip 74 easily goes up by the pressure of the spray liquid and spray gas which are sent in from inside the container 1.
  • the connecting hole 43 opens immediately by the action of the thrusting means 6 to feed spray liquid and, if its pressure goes up, the connecting hole 43 closes, thus maintaining the internal pressure W2 of the pools 44, 45 about constant at all times.
  • vaporized gases are used as spraying gas. Because those vaporized gases (especially N2) are difficult to dissolve in the spray liquid, it is rather difficult to atomize the spray liquid and obtain fine mist.
  • LPG liquid propane
  • DME dimethyl ether
  • other liquefied gases can be used as desired.
  • this liquefied gas can be easily dissolved in the spray liquid, it is sprayed from the spraying hole 7 into the atmosphere together with the spray liquid. As the liquefied gas swells by sudden vaporization, the spray liquid also turns into fine mist.
  • liquefied gas is used for the purpose of turning the spray liquid into fine mist after the spraying, and only a very small amount is enough as the dosage of liquefied gas in the spray liquid, because the injection itself of the spray liquid is performed by the pressure of the vaporized gas.
  • LPG dissolves well in alcohol but hardly dissolves in water and, moreover, the range of amount available for dissolution also changes depending on the set pressure of spraying, i.e. the pressure in the container 1 by vaporized gas.
  • Table 1 shows a concrete example of the relation among the spray liquid, liquefied gas and set pressure for injection, i.e. the pressure in the container 1 by vaporized gas.
  • Injection set pressure Spray liquid Liquefied gas (A) 1 kg/cm 2 99% alcohol 100 wt LPG 5.26 wt (B) 2 kg/cm 2 Same as (A) LPG 10.87 wt (C) 3 kg/cm 2 Same as (A) LPG 20.67 wt (D) 1 kg/cm 2 Same as (A) DME 11.36 wt (E 2 kg/cm 2 Same as (A) DME 27.03 wt (F) 3 kg/cm 2 Same as (A) DME 52.08 wt (G) 1 kg/cm 2 Refined water 100 wt DME 4.79 wt (H) 2 kg/cm 2 Same as (G) DME 9.50 wt (I) 3 kg/cm 2 Same as (G) DME 14.60 wt (J
  • This Table 1 shows the possible range of the dissolved amount of liquefied gas in the case where spray liquid and injection set pressure are given.
  • (A) in Table 1 shows that, in the case where the inject set pressure i.e. the pressure in the container 1 by vaporized gas is 1 kg/cm 2 , the liquefied gas composed of LPG can be dissolved to an amount of 5.26 wt in 100 wt of spray liquid made of 99 % alcohol. Therefore, what is to be done is to dissolve a proper amount no more than 5.26 wt of liquefied gas composed of LPG in 100 wt of spray liquid made of 99% alcohol and store it in the container 1.
  • the temperature of spray liquid and liquefied gas is 25 and, at this temperature, LPG has a pressure of 4. kg/cm 2 and DME has a pressure of 4.7 kg/cm 2 .
  • the spray liquid to be injected from the nozzle hole at a proper pressure from the pools and the reservoir is once stored in those pools and reservoir, and is sent into the spray hole after being raised to the prescribed pressure, and therefore the spray liquid can be injected from the spray hole always at prescribed pressure constantly remaining in the pools and reservoir regardless of the internal pressure of the container.
  • the sliding member 5 has an outer circumference 53 of cylindrical shape, and this cylindrical outer circumference 53 serves as guide for vertical sliding, enabling smooth vertical slide without causing any rolling of the sliding member 5.
  • the present invention provides a spray mechanism of aerosol product capable of maintaining constant spray state and state of mist at all times from beginning to end of use, even in the case where the spray liquid is injected by vaporized gas.
