JP-A-7-147875 JP-A-10-287504 Japanese Patent Laid-Open No. 11-308958

Conventionally, a fire extinguisher aerosol product is known as an aerosol product for injecting a large amount of aerosol composition (contents). In this fire extinguisher aerosol product, a so-called mass injection type aerosol valve that injects all or part of the contents filled in the container in a short time has been used.
In recent years, the use of an aerosol product that sprays a large amount of an aerosol composition in a short period of time as an insecticide has been studied. Patent Document 1 discloses a disinfecting method using an aerosol product characterized by spraying 5 g or more per second for the purpose of adhering a large amount of insecticide to a pest in a short time.
Further, Patent Document 2 and Patent Document 3 describe aerosol products that suppress (knock down) the movement of pests due to the physical effect of the projectiles associated with a large injection flow rate, by increasing the proportion of the solvent in the stock solution. An aerosol product that can efficiently use the insecticide in the stock solution is disclosed.

  Patent Documents 1, 2, and 3 disclose an aerosol product having a large spray amount of the propellant (aerosol composition) and describes that its action is excellent in pest control. However, when using these aerosol products, it is necessary to rely on the user's intuition for injection of the total injection amount necessary to obtain the effect of the aerosol composition. Therefore, it is easy to spray an aerosol composition other than the spray target, which tends to perform excessive spraying, for example, the sprayed material diffused in the space falls and adheres to the floor surface, making the floor surface dirty or slippery. Problems are likely to occur and may be difficult and inefficient for those who are new to the product. In addition, aerosol products for pesticides use a large amount of flammable material, and as long as the stem is kept pressed, a large amount of injection is performed continuously, so the danger to the fire is great.

  In view of these problems, it is an object of the present invention to provide an aerosol product that efficiently uses the contents and prevents a fire risk, by preventing the ejection of the contents more than necessary.

  The aerosol product of the present invention (Claim 1) comprises an aerosol container having a valve secured to the opening of a pressure-resistant container and an aerosol composition filled in the aerosol container, and is located in the valve immediately after the valve is opened. It is characterized in that a large amount of a fixed amount of aerosol composition is injected, and then a small amount is automatically injected.

  In such an aerosol product, the injection amount per unit time of the mass injection (hereinafter simply referred to as injection amount) (M1) is 4 to 50 g / second, and the injection amount (M2) of the small injection is 1 g. / Second or less is preferable (Claim 2). The aerosol composition preferably contains 70% by weight or more of combustible material (claim 3). Furthermore, it is preferable that the injection time for injection at the injection amount (M1) is 0.05 to 2 seconds.

  The valve has a valve having an open hole through which the aerosol composition to be injected passes, and an introduction hole for introducing the aerosol composition into the valve. What is 50 to 20,000 times the area is preferred (Claim 5).

  Further, the valve has an open hole through which the aerosol composition to be injected passes, an introduction hole for introducing the aerosol composition into the valve, and the introduction hole is disconnected when the inside of the aerosol container communicates with the atmosphere. There may be provided a closing valve for reducing or closing the area, and a return means for opening the introduction hole reduced or closed by the closing valve when the inside of the aerosol container and the atmosphere are shut off (claim 6). The valve moves up and down in the valve, and it is preferable that a closing valve is provided at the lower end of the valve.

  The aerosol product of the present invention (Claim 1) immediately injects a large amount of a predetermined amount of the aerosol composition in the valve that is first introduced immediately after the valve is opened, and then automatically injects a small amount. The predetermined amount of the aerosol composition injected in step 1 becomes one lump and reaches the target space or object. In addition, the user can recognize that a predetermined amount of the aerosol composition has been injected based on the difference between the injection amount of the large amount injection and the small amount injection. Therefore, excessive injection of the aerosol composition can be prevented. Here, the small amount injection includes stopping the injection.

  In such an aerosol product, when the injection quantity (M1) of the large quantity injection is 4 to 50 g / sec and the injection quantity (M2) of the small quantity injection is 1 g / sec or less, the difference in the injection quantity is more obvious. In addition to making it easier to visually confirm that a predetermined amount of the aerosol composition has been injected, it is also possible to confirm by hearing through the change in the injection sound and by feeling the gripped hand by changing the reaction force of the injection. Can do. Moreover, since the injection amount (M1) of mass injection is 4 to 50 g / second, the propelling force of the aerosol composition is large and difficult to diffuse at a distance close to the injection hole, and a high concentration aerosol composition ( A state where the density of the ejected particles is high). When the injection amount of the large-volume injection is larger than 50 g / sec, it is difficult for the user to handle and it is difficult to grasp the total injection amount, and it is difficult to adjust. When the injection amount (M1) is smaller than 4 g / sec, sufficient propelling force is not given to the aerosol composition, it is easy to diffuse at a distance close to the injection hole, and it becomes difficult to give a high concentration aerosol composition to the target object. . When the injection amount of the small amount injection is larger than 1 g / sec, it becomes difficult to recognize the difference in the injection amount (Claim 2).

  In addition, when the aerosol composition contains 70% by weight or more of combustible materials, a predetermined amount of the aerosol composition is injected in a short time by mass injection even after filling such contents, and then automatically Since the aerosol composition injected as a small amount is in one lump, the danger to fire is low (Claim 3).

  In such an aerosol product, when the injection time of the mass injection is 0.05 to 2 seconds (Claim 4), in order to inject a predetermined amount of highly flammable aerosol composition in a very short time, Higher safety against fire. Furthermore, since the sprayed aerosol composition becomes a high-concentration lump and diffuses or adheres to the target space or site, the effect can be efficiently exhibited.

  In such an aerosol product, the aerosol product has a valve having an open hole through which the aerosol composition injected from the valve passes, and an introduction hole through which the aerosol composition is introduced into the valve. When the cross-sectional area of the introduction hole is 50 to 20,000 times (Claim 5), when a valve is opened by performing an injection operation, a predetermined amount of aerosol composition in the valve (passage) between the opening hole and the introduction hole first A thing is injected by the injection quantity (M1) of mass injection depending on the cross-sectional area of an open hole. After a predetermined amount of the aerosol composition is injected, the aerosol composition is supplied into the passage from the pressure vessel through the introduction hole. That is, the injection amount of the small injection depends on the cross-sectional area of the introduction hole. Therefore, a difference arises between the injection quantity of large quantity injection and the injection quantity of small quantity injection, and the user can recognize the change of the injection quantity clearly. The open hole and the introduction hole may be an open passage or an introduction passage.

  Further, when the valve has an open hole through which the aerosol composition to be injected passes, an introduction hole through which the aerosol composition is introduced into the valve, and the inside of the aerosol container communicates with the atmosphere by opening the valve In the case where a closing valve for reducing or closing the cross-sectional area of the introduction hole is provided (Claim 6), the cross-sectional area of the introduction hole is reduced when the valve is opened by performing an injection operation. For this reason, the injection amount of the first large amount of injection depends on the cross-sectional area of the open hole, and the injection amount of the small amount of injection depends on the cross-sectional area of the introduction hole after reduction. Therefore, the change between the injection quantity of the large quantity injection and the injection quantity of the small quantity injection becomes clearer. In addition, the sprayed aerosol composition is likely to be agglomerated, has little diffusion to unnecessary portions, and can be applied at a high concentration only to the target site. Here, the closing valve for reducing the cross-sectional area includes a valve that completely blocks the introduction hole, and in this case, the injection amount becomes zero.

  In addition, since the valve operation is stopped and the inside of the aerosol container is shut off from the atmosphere, a return means is provided to open the introduction hole that has been reduced or closed by the shut-off valve. The aerosol composition can be refilled in a short time into the passage between the open hole and the introduction hole. Therefore, continuous use in a short time is possible.

  Furthermore, when the valve moves up and down in the valve and a closing valve is provided at the lower end of the valve (Claim 7), the closing valve can be reliably operated by the valve operation. The introduction hole can be easily reduced or closed by the stop valve.

  Next, the aerosol product of the present invention will be described with reference to the drawings. 1 is a cross-sectional view showing an embodiment of the aerosol product of the present invention, FIG. 2a is an enlarged cross-sectional view showing a valve used in the aerosol product of FIG. 1, and FIG. 2b is another implementation of the valve that can be used in FIG. 2a. 3a is a partial cross-sectional view showing another embodiment of a dip tube used in the valve of FIG. 2, FIG. 3b is a cross-sectional view taken along line XX of FIG. 3a, and FIGS. 3c and 3d are FIG.

Cross-sectional view showing the embodiment, Fig. 15 is a sectional view showing still another embodiment of the injection member which can be used in the aerosol products of the present invention.

  An aerosol container 10 shown in FIG. 1 includes a bottomed cylindrical pressure resistant container 11 having an opening at the upper end, and a valve 12 attached to the opening of the pressure resistant container. When the aerosol container A is filled with the aerosol composition A (stock solution and propellant) and the injection member 13 having the injection hole 14 is attached to the valve 12, the aerosol product 1 is obtained.

  The pressure vessel 11 is formed in a bottomed cylindrical shape having a body portion and a bottom portion by drawing or impacting a metal plate such as aluminum or tinplate. Next, a shoulder portion and / or a neck portion is formed on the upper end of the trunk portion by necking or the like, and a bead portion 15 is formed by curling the upper end of the neck portion. The bottom portion 16 is formed in a mountain shape that rises in a tapered shape toward the center. Thereby, the pressure resistance of the container with respect to the internal pressure is increased and is not easily deformed. In addition, you may use the thing of other materials which have pressure | voltage resistance, such as a synthetic resin and pressure | voltage resistant glass.

  As shown in FIG. 2a, the valve 12 includes a mounting cup 21 fixed to the bead portion 15 of the pressure vessel, a cylindrical housing 22 held at the center of the lower surface of the mounting cup, and freely movable up and down within the housing. A valve 24 having an open hole 23, a cylindrical adapter 25 provided at the lower end of the housing 22, and a dip tube 26 extending from the lower end of the adapter to the bottom 16 of the pressure vessel body. A flow restrictor 27 is provided at the lower end of the tube.

The mounting cup 21 includes a curved flange 32 that is crimped to the bead part 15 via a sealing material 31, a bottomed cylindrical housing holding part 33 that holds the housing 22, and an opening part 34 through which the valve 24 passes. It is a conventionally well-known thing.
The housing 22 has a cylindrical shape, and is disposed between the mounting cup 21 and a spring 35 that constantly urges the valve 24 upward. The gasket 24 is inserted into the inner diameter surface of the housing 22 and provided at the upper end. And.

The valve 24 includes a valve rod 41 having an open hole 23 formed in a lower side surface, an opening 17 provided at an upper end, an intra-valve passage 43 communicating the open hole 23 and the opening 17, and an upper end edge. It consists of a bottomed cylindrical valve plate 44 acting as a seal part 42. The valve 24 is formed by fitting the valve rod 41 into the valve plate 44. Further, one end of a spring 35 is disposed at the lower end of the valve plate 44, whereby the valve 24 is always urged upward. The total cross-sectional area of the open hole 23 is 1.5 to 30 mm ² , preferably ^{2 to 20} mm ² , particularly preferably 3 to 15 mm ² , and the cross-sectional area of the opening 17 is preferably larger than the cross-sectional area of the open hole 23. .
The valve 24b shown in FIG. 2b includes an open hole 23 formed in a side surface, an opening 17 provided at the upper end, and a valve passage 43 communicating the open hole 23 and the opening 17, and the valve rod of the valve 24 41 and the valve plate 44 are integrated. However, unlike the valve 24, the open hole 24 directly engages with the sealing material 31. That is, when the valve is closed, the opening hole 24 is closed by the sealing material 31, and the opening hole 24 is opened from the sealing material 31 by pushing down the valve 24b.

When the cross-sectional area of the open hole 23 is smaller than 1.5 mm ^2, the injection amount (M1) at the time of mass injection becomes small, the propulsive force of the injected aerosol composition is small, and it is easy to diffuse over a wide range at a distance close to the injection hole. Therefore, the aerosol composition cannot be applied to the target product at a high concentration. Moreover, since the injection time which injects a desired amount of aerosol composition becomes long, the safety | security with respect to a fire tends to fall. On the other hand, when the cross-sectional area of the open hole 23 exceeds 30 mm ² , the injection amount becomes large, and the reaction force of the injection becomes so large that it is easy to cause a problem such as being easily detached from the target. The cross-sectional area of the open holes is the sum of the cross-sectional areas of the open holes when there are a plurality of open holes.

The flow restrictor 27 has a cylindrical shape with a lower bottom, and the cross-sectional area of the lower bottom is 0.001 to 0.2 mm ² , preferably 0.005 to 0.15 mm ² , particularly preferably 0.01 to 0. A 1 mm ² introduction hole 28 is formed. When the cross-sectional area of the introduction hole 28 is smaller than 0.001 mm ² , the supply amount into the valve is reduced at the time of injection, and the aerosol composition in the valve tends to stay and changes from large-volume injection to small-volume injection. Tends to be long. In addition, after the injection is completed, it takes time to supply the valve, so it cannot be used repeatedly in a short time. On the other hand, if the cross-sectional area of the introduction hole 28 exceeds 0.2 mm ² , the injection amount (M2) of the small amount injection after the large amount injection becomes large, and this injection tends to reduce the safety against fire, Difficult to understand the difference from mass injection. The cross-sectional area of the introduction holes is also the sum of the cross-sectional areas of the introduction holes when there are a plurality of introduction holes, similarly to the open holes.
Further, the cross-sectional area of the opening hole 23 of the valve 24 is preferably 50 to 20000 times, more preferably 100 to 15000 times the cross-sectional area of the introduction hole 28, so that a change from a large amount injection to a small amount injection is achieved. Can be recognized easily and continuous injection can be performed.

  Since the valve 12 is configured in this way, the valve 24 is always pressed upward by the spring 35. That is, the seal portion 42 of the valve plate 44 presses the gasket 36 and closes the valve 12 in an airtight manner. Then, by depressing the valve 24 (injection operation), the seal between the seal portion 42 and the gasket 36 is released, the valve 24 is opened, and the inside of the aerosol container communicates with the atmosphere, and the aerosol composition in the valve Is injected.

  In this valve, immediately after the valve is released, the aerosol composition B in the passage (inside the valve) from the introduction hole 28 to the opening hole 23 introduced before the valve release is injected. For example, it can be adjusted by the volume of the housing, the position where the introduction hole is provided, the volume of the adapter, the volume in the dip tube, and the like. In addition, the capacity | capacitance in a preferable valve | bulb is 0.2-20 ml, and is 0.5-15 ml especially.

  The aerosol container thus configured is filled with the aerosol composition (stock solution + propellant) as follows. First, the pressure vessel 11 is filled with the stock solution, and the valve 12 is temporarily placed in the opening of the pressure vessel. Next, the propellant is filled from between the valve 12 and the pressure vessel 11 (under cup filling). Then, the valve 12 is pressed from above, and the mounting cup 21 of the valve is crimped and fixed to the bead portion 15 of the pressure vessel 11. Furthermore, the aerosol product 1 is completed by attaching the injection member 13 to the valve 24.

  The injection member 13 includes an injection hole 14 for releasing the aerosol composition to the atmosphere, a mounting part for mounting on the valve rod, and an injection passage for communicating the injection hole and the mounting part. The cross-sectional areas of the injection hole and the injection passage are preferably the same as or larger than the cross-sectional area of the opening hole 23. In addition, although a mechanical breakup mechanism may be provided in an injection hole, it is preferable to make it straight shape in order to provide a high concentration aerosol composition to a target object without diffusing at a short distance from the injection hole. Also, the injection passage may be a forward taper shape that widens toward the tip, or a reverse taper shape that narrows toward the tip, depending on the size of the target object. Good. In addition, when the force which pushes down an injection member is inadequate, a large amount injection as a design may not be performed without an open hole opening completely. Therefore, as will be described later, it is preferable to use an injection member that can fully open the opening hole by reliably lowering the valve using the lever principle.

  The aerosol product 1 in which the aerosol container 10 is filled with the aerosol composition A (stock solution and propellant) operates as follows. When the injection member 13 is first pushed down and the valve 12 is opened, the aerosol composition B in the valve introduced first is injected at an injection amount of 4 to 50 g / sec depending on the cross-sectional area of the opening hole 23 (mass injection). ). Since the aerosol composition B in the valve introduced here is injected at an injection amount of 4 to 50 g / second in only 0.05 to 2 seconds, the injected aerosol composition is close to the injection hole 14. It does not diffuse at a distance, and a high-concentration aerosol composition reaches an object far away and exhibits an effect. In particular, the injection amount (M1) is preferably 5 to 40 g / sec. The injection time at this time can be adjusted by the injection amount (g / sec) and the injection capacity (volume in the valve (ml)), and is 0.05 from the viewpoints of diffusibility in space and safety against fire. ˜2 seconds, more preferably 0.07 to 1 second, and particularly preferably 0.1 to 0.5 seconds.

Further, after the aerosol composition B in the valve introduced first is injected, the aerosol composition A is supplied into the valve from the pressure vessel through the flow restrictor 27, and this supply speed is the injection amount of the small amount injection. (M2). This injection amount depends on the cross-sectional area of the introduction hole 28, and the speed thereof is smaller than 1 g / second, preferably smaller than 0.2 g / second (micro injection).
By setting the injection amount of the small amount injection within the above range, the aerosol composition A is supplied to the valve with a small amount of injection even during a large amount of injection, so the aerosol composition B in the valve is pressure resistant. It communicates with the aerosol composition A in the container, so that the aerosol composition does not stay in the valve, and a large amount of the aerosol composition in the valve can be injected without lowering the flow rate. Therefore, the change from large injection to small injection becomes smooth. Further, when the small amount is injected, the aerosol composition supplied into the valve boils in the valve (in the adapter or the housing) and vaporizes, so the change in the injection state becomes large.

  In this way, after a large amount of injection, it automatically becomes a small amount injection, and since there is a difference between the injection amount (M1) at the time of large amount injection and the injection amount (M2) at the time of small amount injection, it is first introduced into the valve The applied aerosol composition B is sprayed onto the object as one lump. In addition, the user can feel the change or feel it visually or even by a change in the injection amount sound, and can feel that the injection of the aerosol composition B first introduced into the valve is completed. Therefore, the user can prevent the injection of the aerosol composition more than necessary for one injection by stopping the injection operation when this change occurs.

  The aerosol composition used for the aerosol product of the present invention comprises a stock solution containing an active ingredient and a propellant.

The active ingredient is a product application (for example, household, vehicle, industrial products such as insecticide, pest repellent, deodorant, fragrance, refreshing agent, disinfectant, and detergent) and purpose. The solvent is selected appropriately depending on the solvent and / or mixed with the liquefied gas.
Examples of the active ingredient include insecticidal ingredients such as phthalthrin, imiprothrin, allethrin, permethrin, cismethrin, propulserin, resmethrin, d-phenothrin, tefluthrin, benfluthrin, neopinamine forte, chrislonforte; Insecticide enhancing components such as toxite and octachlorodipropyl ether; pest repellent components such as N, N-diethyl-m-toluamide (diet) and caprylic acid diethylamide; lauric acid methacrylate, methyl benzoate, methyl phenylacetate, geranyl Deodorant ingredients such as crotolate, acetophenone myristate, benzyl acetate, benzyl propionate, tea extract; paraoxybenzoate, sodium benzoate, potassium sorbate, phenoxy Bactericidal and antiseptic components such as ethanol, benzalkonium chloride, benzethonium chloride, chlorhexidine chloride, photosensitizer, parachlormetacresol, silver; menthol (l-menthol, dl-menthol, etc.), camphor (d-camphor, dl-camphor) Refreshing ingredients such as mint oil, eucalyptus oil, orange oil, rosemary oil and other essential oil ingredients; detergents such as various surfactants, limonene and enzymes; and natural and synthetic fragrances.

  Examples of the solvent include lower alcohols such as ethanol and isopropanol; polyhydric alcohols such as glycerin, propylene glycol, and 1,3-butylene glycol; water such as purified water and ion-exchanged water; isopentane, kerosene, isoparaffin, and liquid paraffin. Liquid oils such as isopropyl myristate, isopropyl palmitate, and isononyl isononyl oil; silicone oils such as methylpolysiloxane, decamethyltetrasiloxane, and octamethylcyclotetrasiloxane.

  In the stock solution, in addition to the active ingredient, a surfactant such as a nonionic surfactant for the purpose of facilitating adhesion to an injection target such as a pest; hydroxyethyl cellulose, xanthan gum, carboxyvinyl polymer, dextrin palmitate Thickeners such as: Citric acid, triethanolamine, diisopropanolamine and other pH adjusters (stabilizers); Auxiliary ingredients such as silica, talc, zeolite, zinc oxide, nylon powder, silicone powder, etc. can do. When the powder is mixed in the contents as described above, there is a problem that the powder causes clogging in the valve in the aerosol container having a complicated structure in the valve such as the quantitative means or the injection amount converting means. However, the aerosol container of the present invention is preferably at least temporarily temporarily ejected in large quantities, thereby agitating the inside of the valve and preventing clogging.

  The stock solution can be prepared by dissolving or dispersing active ingredients and auxiliary ingredients in a solvent. The stock solution is preferably a homogeneous system in which the blended components are dissolved in a solvent, but may be an emulsified (emulsion) or phase-separated heterogeneous system. Moreover, it is good also considering only an active ingredient as a stock solution without using a solvent.

  As the propellant, it is preferable to use a liquefied gas such as liquefied petroleum gas, dimethyl ether, or a mixture of liquefied petroleum gas and dimethyl ether. In addition, a compressed gas such as nitrogen gas, carbon dioxide gas, nitrous oxide gas, oxygen gas, or compressed air may be blended so that the fuel can be injected without lowering the performance even at low temperatures.

  The mixing ratio of the stock solution and the propellant is preferably 40/60 to 1/99 (weight ratio), more preferably 30/70 to 5/95. When the blending ratio is larger than 40/60 (when the blending amount of the stock solution is large), the sprayed mist is difficult to spread and the effect of the active ingredient is difficult to be obtained. On the other hand, when the blending ratio is less than 1/99, the blending amount of the stock solution (active ingredient) decreases, and it is necessary to inject excessively in order to obtain a desired effect. As the aerosol composition, a homogeneous system in which the stock solution and the propellant are compatible is preferable. However, a heterogeneous system in which the stock solution and the propellant are emulsified or phase-separated, and also a dispersion system in which the powder is dispersed in the aerosol composition. Good.

  In addition, since the aerosol product of the present invention is injected in a short time with a specific injection amount, the safety against fire is high, so lower alcohol such as ethanol, liquid hydrocarbon, ester oil, silicone oil, liquefied gas In the aerosol composition, 70% by weight or more, further 80% by weight or more can be contained.

  The aerosol product of the present invention can be sprayed in the form of a mist on the spray target, but the spray may be adhered to the spray target by blending synthetic resin such as acrylic resin and polyurethane. In this case, the insects can be sprayed on insects such as cockroaches and covered with a resin coating to be exterminated.

  FIG. 3a shows another embodiment of a dip tube 26a that can be used in the valve of FIG. The dip tube 26a is provided with a capillary tube 49 at the upper end for suppressing the flow rate into the valve. Thus, the same function as the flow restrictor 27 in FIG. In this case, the volume of the aerosol composition in the valve in the valve is the volume of the aerosol composition in the space between the seal portion 42 and the capillary tube 49. The cross-sectional area of the passage Y of the capillary tube 49 (see FIG. 3b) is the cross-sectional area of the introduction hole 28. The capillary tube 49 may be provided in a part of the dip tube 26a as shown in FIG. Further, as shown in FIG. 3c, for example, a flow resistor 52 formed by twisting seven core members 51, and further, a coil 53 is tightly wound around the outer periphery of the core member 51 as shown in FIG. 3d. Instead of the capillary tube 49, a flow resistor 54 (not shown) provided with a longitudinal groove extending in the axial direction on the outer periphery of the core member may be used. In the case of the flow resistance body 52, the gap between the core material and the gap between the core material and the dip tube serve as a passage, and the sectional area of the passage becomes the sectional area of the introduction hole. In the case of the flow resistor 54, the gap between the coil and the core material and the gap between the coil and the dip tube serve as a passage, and the sectional area of the passage serves as the sectional area of the introduction hole. Furthermore, in the case of a flow resistor, the longitudinal groove is a passage, and the sectional area of the longitudinal groove is the sectional area of the passage. Furthermore, although the flow resistance is inserted into the dip tube, it may be inserted into the cylinder at the lower end of the adapter, and in this case, the dip tube can be mounted outside the cylinder.

FIG. 4 shows a valve 50 that can be used in the aerosol product 1 of FIG. This valve 50 includes a piston 56 that slides up and down in the adapter 55, a spring 57 that constantly biases the piston 56 downward, and a normal dip that does not have a flow rate restraining means at the lower end of the adapter 55. A tube 58 is provided, and the other configuration is substantially the same as the valve 12 of FIG. 2a.
The piston 56 has an upper bottom cylindrical shape. A communication hole 59 having a small cross-sectional area is formed on the upper base, and a side communication hole 56 a having a cross-sectional area larger than the communication hole 59 is formed on a side surface. ing. Further, a capillary tube may be fitted into the communication hole 59. Here, the communication hole 59 and the side surface communication hole 56a function as an introduction hole of the present invention.
When the valve 50 is used, the inside of the valve means a space between the seal portion 42 and the piston 56 when arranged at the lower end of the adapter.

  The aerosol product 1a provided with the valve 50 operates as follows. When the user performs an injection operation, the aerosol composition B in the valve introduced first is injected at an injection amount (M1) of 4 to 50 g / sec (mass injection). At the same time, the inside of the valve is depressurized, the piston 56 rises, and comes into contact with the lower end of the housing 22. At this time, since the piston 56 closes the lower end of the housing 22 and the side surface communication hole 56a, the injection amount depends only on the communication hole 59, and automatically decreases rapidly. That is, the aerosol composition flows into the valve from the pressure vessel through the communication hole 59 formed in the piston 56. Therefore, after mass injection, the supply rate (1 g / second or less) of the aerosol composition flowing into the valve through this communication hole becomes the injection amount (M2) of the small amount injection. Thereby, the user can recognize the change of the injection amount, and can recognize that the predetermined amount of the aerosol composition B introduced into the valve at the time is first injected.

  In this embodiment as well, since the aerosol composition is supplied in a small injection amount into the valve during mass injection, the aerosol composition in the valve does not stay and changes to small injection. Smooth. In addition, since the aerosol composition boils and vaporizes in the valve during small amount injection, the change in the injection state becomes clear. When the injection operation is stopped and the valve 50 is closed, the aerosol composition is refilled in the valve (in the housing 22) from the pressure-resistant container (dip tube 58) through the communication hole 59 formed in the piston. Since the piston 56 returns to the bottom of the adapter 55 by the force of the spring 57 before the internal pressure in the valve and the pressure vessel becomes substantially the same, refilling in the valve causes the side communication hole 56a and the communication hole 59 to be refilled. Done through. Since it is comprised in this way, the refill in a valve | bulb can be made quick, and the continuous use of this aerosol product is attained. In this embodiment, the piston 56 acts as a closing valve, and the spring 57 and the communication hole 59 act as return means. The spring 57 is not necessarily provided, and may be lowered by the weight of the piston 56.

5 includes a ball 62 that moves up and down in the adapter 61, a spring 63 that constantly biases the ball 62 downward, and a normal dip tube 64 at the lower end of the adapter 61. A slit 65 is formed at the lower end of the housing 22.
When the valve 60 is used, the inside of the valve refers to a space between the seal portion 42 and the ball 62 when disposed at the lower end of the adapter 61.

  When the valve of the aerosol product provided with this valve 60 is opened, the aerosol composition B in the valve is injected at an injection amount of 4 to 50 g / sec (mass injection). At the same time, the ball 62 rises and closes the lower end of the housing 22. At this time, similarly to the valve 50 of FIG. 4, the ball 62 closes the lower end (introduction hole) of the housing leaving the slit 65, so that the injection amount decreases rapidly. Thereafter, the aerosol composition flows from the slit 65 into the valve. Therefore, after a large amount of injection, the supply speed (1 g / second or less) flowing into the valve through the slit 65 becomes the injection amount of the small amount injection. Also in this form, since the aerosol composition is supplied with a small injection amount in the valve at the time of mass injection, the aerosol composition in the valve does not stay and the change to the small injection is smooth. In addition, since the aerosol composition boils and vaporizes in the valve during small amount injection, the change in the injection state becomes clear. After the injection operation is stopped, the aerosol composition is supplied from the slit 65 into the valve in the same manner as the valve 50 in FIG. The ball 62 returns to the bottom of the adapter 61. In this embodiment, the ball 62 acts as a stop valve, and the spring 63 and the slit 65 act as return means. The spring 63 is not necessarily provided and may be lowered by the weight of the ball 62.

The valve 66 shown in FIG. 6 is substantially the same as the valve 60 of FIG. 5 except that a cylindrical elastic body 67 is provided at the lower end of the housing 22 and no slit is formed. is there.
Thus, by providing an elastic body 67 such as synthetic rubber, natural rubber, silicone rubber, or elastomer at the lower end of the housing 22, when the valve 66 is opened, a large amount of the aerosol composition B in the valve is obtained in the same manner as the valve 60 in FIG. Spray. At this time, since the inside of the valve is depressurized, the ball 62 rises and comes into contact with the elastic body 67, the lower end (introduction hole) of the housing 22 is shut off, and the injection automatically stops. That is, in this embodiment, the injection amount of the small amount injection is 0 g / second. When the valve is closed, the seal between the ball 62 and the elastic body 67 is released by the repulsive force of the elastic body and the repulsive force of the spring 63, and the lower end of the housing, which is the introduction hole, is opened. Further, similarly to the valve 60 of FIG. 5, the elastic body 67 may be provided with a slit so that the ball 62 can be easily returned by the repulsive force of the elastic body 67 and the spring 63. In this case, the injection amount of the small amount injection does not become zero. The ball 62 acts as a closing valve, and the elastic body 67 and the spring 63 act as a return means.

The valve 70 in FIG. 7 includes a stop valve using a ball, similar to the valve 60 in FIG. 5, but has no slit formed at the lower end of the housing 22.
This valve 70 is provided with a ball 71 and a spring 72 in an adapter 73 in the same manner as the valve 60 in FIG. 5, and the side surface of the housing 22 communicates with the vapor portion (vapor phase portion) inside the pressure vessel. A hole 74 is formed. The other structure is substantially the same as the valve 60 of FIG.

When the valve 70 is used, the inside of the valve refers to a space between the seal portion 42 and the ball 71 disposed at the lower end of the adapter 73.
In the aerosol product provided with the valve 70, when the valve is closed, the aerosol composition is not stored in the valve because the gas phase portion in the valve and the container communicate with each other. When the valve is opened, the ball rises and seals the lower end of the housing as in the other embodiments, but a large amount of fuel is injected after the valve is opened until the lower end of the housing is sealed. At the time of mass injection, gas is introduced into the projectile through the gas phase communication hole, and the injection amount per unit time (g / second) is slightly smaller than that of the other embodiments, and the safety against fire is high. The injection amount (g) of mass injection can be adjusted by the time until the ball seals the lower end of the housing, depending on the strength of the spring and the cross-sectional area of the gas phase communication hole.

  When the ball 71 is lifted and the lower end (introduction hole) of the housing 22 is sealed, the injection of the aerosol composition stops, and only the gas in the vapor part (the gas phase part of the liquefied gas) in the pressure vessel is continuously injected. (Small amount injection). At this time, the user can recognize the change in the injection amount. Here, when the injection operation is stopped and the valve 70 is closed, the inside of the valve communicates with the vapor portion of the pressure vessel through the side surface communication hole 74, so that the pressure is almost the same as the inside of the pressure vessel. Therefore, the time until the ball 71 is lowered by the force of the spring 72 and the lower end of the housing is opened again is short, and repeated injection can be performed in a short time. The ball 71 functions as a stop valve, and the side surface communication hole 74 functions as a return means. Note that the spring 72 is not necessarily provided, and may be lowered by the weight of the ball 71.

The valve 75 shown in FIG. 8 a includes a slit 76 formed on the upper side surface of the housing 22, a gas phase communication hole 77 formed in the slit, and an annular contact portion 78 formed at the upper end inside the housing. (See FIG. 8b), and the other configuration is substantially the same as the valve 70 shown in FIG.
With this configuration, when the valve 75 is closed, the vapor portion in the pressure vessel and the inside of the valve communicate with each other through the slit 76 and the gas phase communication hole 77. The composition is not stored. When the valve 24 is lowered and the valve 75 is opened, the gasket 36 is bent as the valve 24 is moved, and the gas phase communication hole 77 is blocked by the lower surface of the gasket 36 coming into contact with the annular contact portion 78. Further, when the valve 24 is raised and the valve is closed, the vapor part of the pressure vessel and the inside of the valve communicate again.

  For this reason, when an injection operation is performed using an aerosol product using this valve, the ball 71 rises and a large amount is injected while the lower end of the housing is sealed. In this embodiment, unlike the valve 70 of FIG. 7, the gas phase communication hole is blocked when the valve is open, so that a large amount of injection is performed without decreasing the injection amount per unit time. When a large amount of fuel is injected and the lower end of the housing is sealed, the injection is completely stopped (small amount injection). When the injection operation is stopped here, the vapor portion of the pressure vessel and the inside of the valve communicate again, so that the pressure vessel and the inside of the valve have the same pressure, and the ball 71 is pushed back in a short time by the repulsive force of the spring 72, Return to the original state.

The valve 80 shown in FIG. 9 is one in which the lower end of the housing 22 is sealed with a closed object 81 when the valve is opened, and the seal structure by the engagement between the lower end of the housing and the closed object is easily released by applying a force from the outside. It is what is done.
The configuration of the valve 80 is that there is no flow restriction, a closed object 81 is provided in the adapter, and the area of the lower end opening 22a of the housing is tapered downward, as shown in FIG. 2a. The valve 12 and its configuration are substantially the same.
The closing object 81 includes a semicircular upper part 82 and a lower part 83 having an asymmetrical elongated shape, and the upper part and the lower part cannot be reversed within the adapter.
When the valve 80 is used, the inside of the valve refers to a space between the seal portion 42 and the closed object 81 disposed at the lower end of the adapter.

When the valve of the aerosol product provided with this valve 80 is opened, the aerosol composition B in the valve introduced first is injected at an injection amount of 4 to 50 g / sec (mass injection). At the same time, the closing object 81 rises and seals the lower end of the housing 22. Thereby, injection stops. However, since the engagement between the closing object 81 and the lower end of the housing is physically unstable, after the injection operation is stopped, the aerosol product is shaken to the left and right to thereby engage the closing object 81 with the lower end of the housing. As shown by the imaginary line, the aerosol composition flows into the valve. As a result, the closed object 81 is lowered by its own weight when the inside of the valve and the inside of the pressure vessel are at the same pressure.
The shape of the closed object 81 is not limited to the above. For example, as shown in FIG. 9b, an elongated oval closure 81 may be used. Moreover, you may incline the lower end opening part 22b of the housing contact | abutted with a closed thing with respect to a horizontal like FIG. 9c. By providing such a lower end opening of the housing, when the closed object and the lower end of the housing are engaged, sealing is performed in an unstable state.

  As shown in FIG. 9d, a closing object 86 composed of a spherical lower portion 84 and a rod-shaped upper portion 85 may be used in the valve 50 shown in FIG. Accordingly, when the valve 50 is opened and the piston 56 is raised, the closing object 86 is also raised similarly, and the upper portion 85 closes the communication hole 59. Therefore, after a predetermined amount of the aerosol composition in the valve immediately after the valve is opened, the injection stops. By stopping the injection operation and shaking the aerosol product to the left and right, the inclined communication hole 59 is opened as indicated by the imaginary line of the closed object 86, and the valve is filled again.

In the valve 90 shown in FIG. 10, when the valve 93 is lowered, a closing valve 96 provided at the lower end of the valve closes the introduction hole 98 that communicates the inside of the container and the inside of the valve.
The valve 90 is fixed to the pressure vessel by the mounting cup 21 as shown in FIG. 1, and is held at the center of the lower surface of the mounting cup 21 and has a cylindrical housing 91 having a communication hole 91a formed at the bottom thereof. The tubular adapter 95 is composed of a valve 93 which is accommodated in the housing so as to be movable up and down and has an open hole 92, and a spring 94a which constantly urges the valve upward, and is mounted on the lower portion of the housing. And a cylindrical shut-off valve 96 that moves up and down in the adapter, and a second spring 94b that is provided between the bottom of the adapter and the shut-off valve and constantly biases the close-up valve upward.

The adapter 95 is formed with a mounting portion 97 attached to the lower portion of the housing, an introduction hole 98 closed by a shut-off valve 96, and a tube mounting portion 98a for mounting a dip tube.
The closing valve 96 includes an upper part 96 a and a lower part 96 b, and the upper part 96 a moves up and down in the housing through the communication hole 91 a of the housing, and the upper upper end 99 is in contact with the lower end of the valve 93. Further, the lower part 96b is provided with a blade 97 on its side wall so as to guide the vertical movement of the shut-off valve and to crawl the inner wall of the adapter.
a protrudes (see FIG. 10b). Further, a closing member 99a is provided at the lower end of the lower part 96b. The closing member 99a is a ring-shaped elastic body and is attached to the lower lower end 99b of the closing valve.
Accordingly, when the valve 93 is pushed and the closing valve 96 is lowered, the closing member 99a is fitted into the introduction hole 98 in the adapter, and the inside of the container and the inside of the valve are shut off (see FIG. 10c). When the injection operation is stopped, the valve 93 rises, the internal pressure and the second spring 94b raise the shut-off valve 96, the introduction hole 98 is unblocked, and the contents are introduced into the blades 97a and 97a from the introduction hole 98. Filled into the housing and adapter through. It should be noted that the distance between the closing member and the introduction hole is shorter than the distance by which the valve descends, and particularly preferably shorter than the opening distance at which the opening hole of the valve is opened. As a result, since the opening hole is opened after the introduction hole is closed, it is easy to obtain an injection state as designed.

  Since the aerosol product using the valve 90 of FIG. 10 is configured as described above, when the valve 93 is lowered by operating the injection member or the like, the introduction hole 98 in the adapter is closed and the valve 93 is opened. The holes 92 are opened and only a certain amount of the contents filled in the housing and adapter are injected. When the injection operation is stopped, the contents in the container are supplied into the valve from the introduction hole 98. In the case of the valve, it is not necessary to make the introduction hole small. The contents can be filled in and can be injected at short intervals.

The valve 100 shown in FIG. 11 closes the introduction hole 101 that communicates the inside of the container and the inside of the valve by lowering the valve in the same manner as the valve 90 of FIG.
The valve 100 includes a housing body 102a having a cylindrical housing 102, a bottomed cylindrical housing lower part 102b attached to the lower end thereof, and a valve 103 that is always fitted in an opening 102c of the lower housing part 102b. Become.

An elastic body 104 is disposed on the bottom surface of the housing lower part 102 b, and an introduction hole 101 communicating with the outside (inside the container) is formed on a side surface slightly above the elastic body 104. The upper outer periphery of the housing lower part 102b is an engaging part 105 that engages with the housing main body 102a.
The valve 103 includes a bottomed cylindrical upper part 103a with an opening facing upward, a bottomed cylindrical lower part 103b with an opening facing downward, and a cylinder 10 fitted into the upper part 103a.
3c, an open hole 106 is formed on the side surface of the cylinder 103c, and a side surface communication hole 107 is formed on the side surface of the lower portion 103b. Further, like the valve 90 of FIG. 10, a spring 94 is provided to constantly bias the valve upward.

Thus, when the valve 103 is lowered, the lower end of the valve is fitted with the elastic body 104 to seal the opening of the lower part 103b of the valve, and the introduction hole 101 is a side surface of the lower part 103b. Blocked by. On the other hand, since the opening hole 106 of the valve is opened, the contents inside the valve are sprayed to the outside through the opening hole 106 (opening hole) of the cylinder 103c (see FIG. 11b).
When the injection operation is stopped, the valve 103 returns upward by the force of the spring 94 and the opening hole 106 is closed. On the other hand, the opening of the valve lower part 103b and the introduction hole 101 are opened, and the content passes through the valve lower part 103b and is filled into the housing through the side surface communication hole 107.
As a result, the aerosol product having the valve 100 of FIG. 11 as well as the valve 90 of FIG. 10 is filled in the valve housing (including the contents in the lower part 103b of the valve) by operating the injection member or the like. Only a certain amount of contents can be injected.

  12 to 15 show an injection member used in the aerosol product of the present invention. These injection members are configured so that the force required for the injection operation can be easily applied while gripping the aerosol container, and in order to obtain an injection state as designed as in the present invention, It is preferable to use it for aerosol products that require the opening to be fully opened. Moreover, in description of these injection members, let the left side of drawing be a front.

The injection member 110 of FIG. 12 is of a trigger type that injects the contents above the aerosol product, and includes a hollow cover member 111 that fits into the aerosol container, and a trigger member 112 that is attached to the valve of the aerosol container. Consists of.
The cover member 111 is a hollow body composed of a locking portion 113 fitted to the bead portion of the aerosol container and a grip portion 114 that can be held by the palm of the operation, and the upper end is for jetting the contents, and A part (front) of the side wall is opened for the operation of the trigger member (openings 115a and 115b).

  The trigger member 112 includes a main body 119 provided with an attachment portion 116 attached to a valve of the aerosol container, an injection hole 117, and a member internal passage 118 that communicates the attachment portion and the injection hole. The operation unit 120 is connected and arranged so as to protrude from the opening 115b. Further, the main body 119 is provided with an axis 121 supported on the rear inner wall in the cover member, and the trigger member 112 moves up and down around the axis 121.

  Since the ejection member 110 is configured as described above, the user uses the palm or the middle finger on the operation portion 120 of the trigger member while aligning the palm with the grip portion 114. Then, by pulling the finger forward (backward), the trigger member 112 moves in the direction of the arrow, lowers the valve, and opens the valve. When the operation is completed, the finger is released from the operation unit 120, the valve is raised by the action of the repulsive force of the valve (the spring in the valve), and the trigger member returns to the original position. In this way, since the aerosol container can be gripped and sprayed by applying force in one direction, a relatively strong force can be applied to the valve opening in the operation of the aerosol product, and the valve can be pushed down reliably. The opening hole is fully open.

The injection member 125 shown in FIG. 13 is a trigger type, and injects the contents in front of the aerosol product.
The injection member 125 is connected to the base portion 126 fitted to the aerosol container, and the base portion via a hinge portion 127, and is engaged with the injection portion 128 attached to the valve of the aerosol container and the injection portion. The trigger 129.

  The injection part 128 includes a mounting part 133 attached to the valve of the aerosol container, an injection hole 134 for injecting the contents forward, and an L-shaped member inner passage 135 that connects the engagement part and the injection hole. It is an L-shaped square body. An arm 136 connected to the hinge portion 127 is formed behind the injection portion 128.

  The trigger 129 is provided so as to sandwich the injection unit 128, and includes a pressing unit 137 that presses the injection unit downward, a fixing unit 138 that fixes the trigger to the base, and an operation unit 139 that operates the trigger. The trigger is fixed by hooking the fixing portion 138 on the rising wall of the base portion 126.

  Since it is configured in this manner, the aerosol product including the injection member 125 is held by aligning the palm with the grip portion 131a and the finger with the operation portion of the trigger. Then, by pulling the trigger with a finger, the trigger pressing portion 137 pushes the ejection portion 128 downward about the hinge portion 127 (arrow direction). As a result, the valve is surely lowered and the opening hole is fully opened.

The injection member 140 shown in FIG. 14 includes a base portion 141 that is fitted to the bead portion of the aerosol container, and an operation member 143 that is connected to the base portion via the hinge portion 142 and is engaged with the valve of the aerosol container. .
The operation member 143 includes a mounting portion 144 that is mounted on the valve of the aerosol container, an injection hole 145 provided on the front side, and an L-shaped member internal passage 146 that connects the mounting portion and the injection hole. It is a square body, and includes a push plate 147 that protrudes rearward in the horizontal direction from the top.

  Since it is constituted in this way, the aerosol product provided with this injection member 140 grasps the container main part, and pushes down push board 147 with a thumb etc., and performs injection operation. As a result, the operating member 143 descends about the hinge portion 142, the valves engaged with the operating member 143 descend together, and the open hole is fully opened.

  An injection member 150 shown in FIG. 15 has a handle, and includes a base 151 fitted to the aerosol container, a handle 153 provided behind the base via a connecting portion 152, and an operation for lowering the valve. Part 154. Further, the aerosol container shown in FIG. 15 is a three-piece type metal can having a trunk portion 150a, a head portion 150b, and a bottom portion (not shown).

The base portion 151 includes the bead portion 150c and the body portion of the aerosol container, and engaging portions 151a and 151b that fit into the double-tightening 150d of the head portion.

The operation part 154 includes a mounting part 155a attached to the valve, an injection hole 155b, a main body 155 including a member inner passage 155c that connects them, and a push plate 156 that is connected to the main body and lowers the operation part. The push plate 156 protrudes in the same direction as the handle 153, that is, rearward, and the injection hole 155b faces the direction opposite to the handle, that is, forward. A hinge portion 157 protrudes forward from the main body 155. The hinge portion 157 is supported on the inner surface of the base portion 151.
