The air bubble micro-bubble nozzle described in Patent Document 1 requires a nozzle having a special inlet for introducing the atmosphere. Further, this nozzle requires a special structure for mixing the introduced atmosphere and the pressurized water, and is complicated. The cleaning method described in Patent Document 2 does not disclose any mechanism for generating microbubbles, and cannot be implemented.

The present invention has been made in view of such conventional problems, and an object thereof is to provide an injection product capable of pressurizing and injecting a content containing fine bubbles of compressed gas with a simple structure. And

The present invention which solves the above problems mainly includes the following configurations.

(1) A container main body filled with contents, a valve mechanism attached to the container main body, and an injection member attached to the valve mechanism. The contents are for an aqueous stock solution and water at 25°C. And a compressed gas having an Ostwald coefficient of 0.1 or less, wherein the compressed gas is dissolved in the aqueous undiluted solution in an amount of 1 to 1000 ppm, and the valve mechanism is present in a gas phase portion of the container body. A gas discharge hole for discharging compressed gas to the outside and an injection passage for supplying the content to the injection member are formed, and a pump mechanism for pressurizing the content in the injection passage is provided. An injection product, which is provided with the compressed gas in the gas phase portion to the outside by opening the gas release hole by operating the injection member.

With such a configuration, the gas discharge hole of the valve mechanism is opened by operating the injection member, and the compressed gas in the gas phase portion is discharged to the outside. As a result, the inside of the container body communicates with the atmosphere and becomes atmospheric pressure. As a result, the compressed gas dissolved in the contents under high pressure is supersaturated and vaporized, and the contents are in a state in which fine bubbles are dispersed (the fine bubbles have gas release holes). It can occur more easily by shaking the container body after it is opened). In particular, the content consists of an aqueous stock solution and a compressed gas having an Ostwald coefficient for water at 25° C. of 0.1 or less. Since the compressed gas is dissolved in the aqueous stock solution in an amount of 1 to 1000 ppm, the generated bubbles are Very small, does not immediately float and disperses in aqueous stock solutions for a long time. The sprayed product includes a pump mechanism that pressurizes the contents. Therefore, the sprayed product can spray the contents in which such fine bubbles are dispersed. In all of these series of operations, it is not essential to attach a special nozzle, for example. In addition, the contents in which fine bubbles are dispersed can give a cleaning effect by the bubbles to the coated surface, for example.

(2) The pump mechanism includes a housing having a stock solution intake hole for taking in the contents from the container body, a stem slidably accommodated in the housing in the vertical direction, and the stem. The injection product according to (1), further comprising: a piston member that slides vertically in the housing in cooperation with each other, and a check valve mechanism that opens and closes the stock solution intake hole.

With such a configuration, in the pump mechanism, by operating the injection member, the stem and the piston member can cooperate to take the contents into the housing. The pump mechanism also includes a check valve mechanism. Therefore, the taken-in contents do not flow back and are easily stored in the housing. As a result, the sprayed product is likely to be sprayed with an appropriate amount of content, and a stable effect is easily obtained.

(3) The piston member is displaced into a closed state in which the gas release hole is closed and an open state in which the gas release hole is open by sliding the stem, (2) Injected product as described.

According to such a configuration, the injection product can perform the opening/closing operation of the gas release hole via the piston member housed in the housing. Therefore, the size of the sprayed product itself may be small as in the conventional case and is easy to handle. The piston member also cooperates with the operation of the injection member. Therefore, the sprayed product has a simple operation method.

(4) The valve mechanism is displaceable from a non-injection state in which the content is not ejected to an aerosol injection state in which the content is ejected by the pressure of the compressed gas, and in the non-injection state, the stem and the The piston member is in contact so as to block the injection passage, and the valve mechanism is displaced from the non-injection state to the aerosol injection state, whereby the injection passage is blocked by the stem and the piston member. The sprayed product according to (2) or (3), wherein the content that has been released and pressurized by the compressed gas in the container body is supplied from the container body to the spraying member and sprayed.

With such a configuration, the valve mechanism can be displaced to the aerosol injection state in which the content is injected by the pressure of the compressed gas. Therefore, the content can be continuously jetted by such an aerosol jet, and can be jetted vigorously at high pressure. As a result, the sprayed product can remove stains and the like on the coated surface, for example, by the force of the spraying and the physical scrubbing action by vaporization of the compressed gas dissolved in the sprayed contents.

According to the present invention, it is possible to provide an injection product capable of pressurizing and injecting a content containing fine bubbles of compressed gas with a simple structure.

The aqueous stock solution 5 is supplied from the container body 2 to the valve mechanism 3 by operating the injection member 4. Specifically, the aqueous stock solution 5 is taken in from the lower end of the tube 63, passes through the first space S1, or is temporarily stored in the first space S1, and then, the external stem internal passage 75a of the external stem 75 and the injection nozzle. It is supplied to the in-nozzle passage 41d of No. 41 and is ejected from the ejection hole 43a.

・Aqueous stock solution 5
The aqueous stock solution 5 is a liquid component with which the container body 2 is filled. The aqueous stock solution 5 contains conventionally known components. As an example, the aqueous stock solution 5 can include water, alcohol, a surfactant, a thickener, an active ingredient, and the like.

Water is a main solvent of the aqueous stock solution 5 and appropriately dissolves a compressed gas, a water-soluble active ingredient and the like. Examples of water include purified water, ion-exchanged water, physiological saline, and deep sea water.

The content of water in the aqueous stock solution 5 is preferably 50% by mass or more, and more preferably 60% by mass or more. The content of water in the aqueous stock solution 5 is preferably 99.5% by mass or less, and more preferably 99% by mass or less. When the water content is less than 50% by mass, the amount of compressed gas dissolved tends to increase, and fine bubbles are less likely to be generated. On the other hand, when the content of water exceeds 99.5% by mass, the content of the active ingredient, alcohol, etc. becomes small, and it becomes difficult to obtain the effect of the active ingredient.

The alcohol adjusts the concentration at which the compressed gas dissolves in the aqueous stock solution 5, and adjusts the size and amount of bubbles generated in the aqueous stock solution 5 when the compressed gas is discharged to the outside by switching to the pump injection state, and the holding time. It is included for the purpose of doing. Examples of the alcohol include monohydric alcohols having 2 to 3 carbon atoms such as ethanol and isopropanol, and polyhydric alcohols such as propylene glycol, 1,3-butylene glycol, glycerin and sorbitol. These may be used in combination.

When the alcohol is contained, the content of the alcohol in the aqueous stock solution 5 is preferably 1% by mass or more, and more preferably 3% by mass or more. The content of alcohol is preferably 40% by mass or less, and more preferably 35% by mass or less. When the content of alcohol is less than 1% by mass, it becomes difficult to obtain the effect of alcohol. On the other hand, when the alcohol content exceeds 40% by mass, a large amount of compressed gas is dissolved in the aqueous stock solution 5 excessively, and when the valve mechanism 3 is switched to the pump injection state, large bubbles are generated in the aqueous stock solution 5. It will soon float and easily disappear.

The surfactant (solubilizer) is appropriately contained as an active ingredient that dissolves an active ingredient that is insoluble in water and enhances the detergency. The surfactant is not particularly limited. For example, glycerin fatty acid ester, polyglycerin fatty acid ester, sorbitan fatty acid ester, POE sorbitan fatty acid ester, POE hydrogenated castor oil, nonionic surfactant such as POE alkyl ether, POE/POP alkyl ether, and anion such as fatty acid soap. Surfactants, anionic surfactants such as alkyl phosphates, alkyl sulfates, POE alkyl ether sulfates, amphoteric surfactants such as cocamidopropyl betaine and lauryl betaine, amino acid systems such as N-acyl glutamate Examples thereof include surfactants and silicon-based surfactants such as polyoxyethylene/methylpolysiloxane copolymer. These may be used in combination.

When the surfactant is contained, the content of the surfactant in the aqueous stock solution 5 is preferably 0.01% by mass or more, and more preferably 0.05% by mass or more. Further, the content of the surfactant in the aqueous stock solution 5 is preferably 15% by mass or less, and more preferably 10% by mass or less. When the content of the surfactant is less than 0.01% by mass, it is difficult to sufficiently obtain the effect of dissolving the insoluble active ingredient and the effect of increasing the detergency. On the other hand, when the content of the surfactant exceeds 15% by mass, it tends to be difficult to wash off.

The thickener is contained in order to release the compressed gas to the outside to suppress the floating of fine bubbles generated in the aqueous stock solution 5 and to facilitate the maintenance. Examples of the thickener include methyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropyl methyl cellulose, gum arabic, guar gum, locust bean gum, gelatin and the like. These may be used in combination.

When the thickener is contained, the content of the thickener in the aqueous stock solution 5 is preferably 0.01% by mass or more, and more preferably 0.05% by mass or more. Further, the content of the thickener in the aqueous stock solution 5 is preferably 5% by mass or less, and more preferably 3% by mass or less. When the content of the thickener is less than 0.01% by mass, it is difficult to sufficiently obtain the effect of maintaining the bubbles generated by the vaporization of the compressed gas. On the other hand, when the content of the thickener exceeds 5% by mass, the viscosity of the aqueous undiluted solution 5 becomes too high, and it tends to be difficult to eject or the usability tends to deteriorate.

The aqueous stock solution 5 may appropriately contain an active ingredient in addition to the above-mentioned compounding ingredients. For example, the active ingredient is a bactericidal or antibacterial agent such as chlorohexidine, triclosan, cetylpyridinium chloride, zinc gluconate, zinc citrate, and quaternary ammonium salt; pH of citric acid, phosphoric acid, malic acid, lactic acid, etc. Regulators; preservatives such as sodium benzoate, paraoxybenzoate, ethylenediaminetetraacetate, benzalkonium chloride; anti-inflammatory agents such as tranexamic acid, glycyrrhizin dipotassium salt; astringents such as sodium chloride and aluminum lactate; ascorbine Acids, vitamins such as tocopherol esters; extracts such as clove, rosemary, sorghum; moisturizers such as hyaluronic acid; essential oils such as peppermint, peppermint oil, spearmint, fruit-based essences such as lemon and strawberry, l-menthol , Limonene, ocimene, cineole, n-decyl alcohol, citronellol, vanillin, α-terpineol, methyl salicylate, thymol, rosemary oil, sage oil, perilla oil, lemon oil, orange oil and the like; various pigments and the like. These may be used in combination.

When the active ingredient is contained, the content of the active ingredient in the aqueous stock solution 5 is preferably 0.01% by mass or more, and more preferably 0.05% by mass or more. Further, the content of the active ingredient in the aqueous stock solution 5 is preferably 10% by mass or less, and more preferably 5% by mass or less. When the content of the active ingredient is less than 0.01% by mass, it is difficult to sufficiently obtain the effect of the active ingredient. On the other hand, when the content of the active ingredient exceeds 10% by mass, the content tends to have poor stability or poor usability depending on the active ingredient.

-Compressed gas The compressed gas is filled in the container body 2 together with the aqueous stock solution 5, and most of the compressed gas is present in the gas phase in the container body 2 so as to pressurize the aqueous stock solution 5 so that it can be discharged. It acts as an agent and the rest dissolves in the aqueous stock solution 5. The amount of compressed gas to be dissolved may be 1 ppm or more, preferably 1.5 ppm or more, when the compressed gas is filled in the container body 2. Further, the amount of compressed gas dissolved may be 1000 ppm or less, and preferably 500 ppm or less. When the amount of the compressed gas dissolved is less than 1 ppm, the amount of the dissolved gas is too small, so that when the compressed gas is released by switching to pump injection, there are few bubbles generated in the aqueous stock solution 5 and it is less likely to become cloudy. On the other hand, when the amount of the compressed gas dissolved exceeds 1000 ppm, the bubbles generated in the aqueous stock solution 5 become large, and when the valve mechanism 3 is switched to the pump injection state, it immediately floats and disperses in the aqueous stock solution 5. Hard to do. In the present embodiment, the amount of compressed gas dissolved is the amount of compressed gas dissolved in the aqueous stock solution 5 at 25°C.

The compressed gas may have an Ostwald coefficient to water at 25° C. of 0.1 or less, preferably 0.05 or less. When the Ostwald coefficient exceeds 0.1, the amount of dissolution increases, so that fine bubbles are less likely to be generated in the discharged aqueous stock solution 5.

More specifically, the compressed gas includes nitrogen (Ostwald coefficient: 0.0141), oxygen (Ostwald coefficient: 0.0283), hydrogen (Ostwald coefficient: 0.0194), air (0.0167), and the like. Mixed gas etc. are illustrated. As the compressed gas, a gas having a relatively large Ostwald coefficient may be used in combination as long as it is included in the above range of the amount of dissolution. Examples of such a gas include carbon dioxide (Ostwald coefficient: 0.759), nitrous oxide (Ostwald coefficient: 0.59), and the like. Among these, the compressed gas is preferably nitrogen or air because it is easily available, easy to handle, and has little effect on the human body. The compressed gas may be used together.

The pressure in the container body 2 after being filled with compressed gas and saturatedly dissolved in the aqueous undiluted solution 5 is 0.2 to 1.0 MPa (gauge pressure) at 25° C., preferably 0.3 to 0.8 MPa (gauge). Pressure). Such a pressure can be adjusted by filling the compressed gas with the above-mentioned dissolved amount.

<Example of displacement of valve mechanism 3>
Next, the displacement of the valve mechanism 3 in the case of injecting the aqueous undiluted solution 5 using the injection product 1 having the above-described configuration will be described with reference to FIGS. 4 to 6 in addition to FIGS. FIG. 4 is a perspective view for explaining the operation of the switching member 9. FIG. 5 is a schematic enlarged view of the valve mechanism 3 which is displaced to the aerosol injection state for performing the aerosol injection. FIG. 6 is a schematic cross-sectional view of the injection product 1 in which the valve mechanism 3 is displaced to a pump injection state in which pump injection is performed. FIG. 7 is a schematic enlarged view of the valve mechanism 3 which is displaced to a pump injection state in which pump injection is performed. The valve mechanism 3 may be displaced from the non-injection state to the above-described aerosol injection state and then to the pump injection state. However, the injection product 1 of the present embodiment is only required to be able to perform pump injection, and the displacement to the aerosol injection state is not essential. Therefore, in the valve mechanism 3 of the present embodiment, for example, when the ejection member 4 is operated by the user in a short time, the valve mechanism 3 is not substantially displaced to the aerosol injection state (or to the aerosol injection state for a short time). After the displacement), the non-injection state may be displaced to the pump injection state. Further, in the following embodiments, the valve mechanism 3 can be displaced from the non-injection state to the aerosol injection state by rotating the switching member 9, and the valve mechanism 3 can be further displaced to the pump injection state by removing the switching member. Is illustrated. Instead of this, in the injection product 1 of the present embodiment, the length (depth) of the locking groove 41b of the switching member 9 is adjusted, so that the injection nozzle 41 can be inserted through the injection nozzle 41 without removing the switching member 9. It is also possible to employ a mode in which the stem 71 can be pushed further downward and the valve mechanism 3 can be displaced to the pump injection mechanism. Further, the valve mechanism 3 may be displaced to the pump injection mechanism only by removing the switching member 9.

(Non-jetting state)
First, in the non-injection state in which the aqueous undiluted solution 5 is not ejected (before injection), as shown in FIG. 1, the switching member 9 has the contact portion 92 (see FIG. 3) fitted into the main body portion 42c. .. Further, the switching member 9 is appropriately rotated so that the locking projection 95 comes into contact with the lower surface 41c of the injection nozzle 41. In this state, the injection nozzle 41 cannot move downward. As a result, the valve mechanism 3 is brought into a non-injection state in which the contents are not ejected, and the inner stem 74, the outer stem 75 and the piston member 72 are maintained in a state of being biased upward by the spring member 73. In this case, the piston member 72 blocks the communication (injection passage) between the first space S1 and the second space S2 by bringing the lower inner sliding portion 76b into contact with the contact groove 74h, and The gas release hole 61e is closed by the outer sliding portion 77a (closed state). Therefore, the aqueous stock solution 5 is not jetted. Moreover, since the injection nozzle 41 cannot move downward, the aqueous undiluted solution 5 is not accidentally injected.

(Aerosol injection state)
On the other hand, as shown in FIG. 4, when the locking projection 95 of the switching member 9 is rotated to a position corresponding to the locking groove 41b, the valve mechanism 3 causes the aerosol injection state in which the aerosol injection is performed from the non-injection state. Can be easily displaced. Specifically, as shown in FIG. 4, when the locking projection 95 is rotated to a position corresponding to the locking groove 41b, the user can operate the trigger portion 42i. As a result, when the ejection nozzle 41 is pushed downward in a possible range, the locking projection 95 is inserted into the locking groove 41b and locked. As a result, the inner stem 74 and the outer stem 75 slide integrally downward. At this time, the piston member 72 does not move because it does not contact the outer stem 75, and the inner stem 74 and the outer stem 75 descend by the depth of the locking groove 41b (the height of the locking projection 95). As a result, as shown in FIG. 5, this displacement causes the lower end of the lower inner sliding portion 76b to separate from the contact groove 74h. This allows the first space S1 and the second space S2 to communicate with each other. That is, the inside of the container body 2 is communicated with the outside. At this time, the gas discharge hole 61e remains closed by the upper outer sliding portion 77a. When the inside of the container body 2 is communicated with the outside, the inside of the container body 2 is pressurized by the compressed gas, so the aqueous stock solution 5 pressurized by the compressed gas lifts the ball 65b upward, It is supplied to one space S1. Furthermore, the aqueous stock solution 5 is supplied to the second space S2, passes through the external stem internal passage 75a, and is jetted from the jet holes 43a (see FIG. 1). As described above, in the aerosol injection state, the aqueous stock solution 5 is continuously injected by the pressing force of the compressed gas. In FIG. 5, an arrow A1 indicates the flow of the aqueous stock solution 5 taken in from the container body 2.

In the aerosol spray state, the contents are vigorously sprayed by the compressed gas filled under pressure. Further, even if the trigger part 42i is not repeatedly operated, the required amount can be continuously ejected if it is maintained in the operated state. Therefore, the sprayed product 1 can remove stains and the like on the coated surface, for example, by the force of the spraying and the physical scrubbing action by vaporization of the compressed gas dissolved in the sprayed contents.

(Bubbling condition)
When the switching member 9 (see FIGS. 3 and 4) is removed, the valve mechanism 3 can be easily displaced from the non-injection state or the aerosol injection state to the pump injection state. At this time, the valve mechanism 3 goes through a bubble generation state in which bubbles of compressed gas are generated. Specifically, as shown in FIG. 6, when the switching member 9 is removed, the user can further operate the trigger portion 42i (see FIG. 1), and the injection nozzle 41 is in the aerosol injection state (FIG. (Refer to 5) and further pushed downward as much as possible. At this time, as shown in FIG. 7, the inner stem 74 and the outer stem 75 are integrated until the contact step 75d of the skirt 75b contacts the upper end of the upper inner sliding part 76a of the piston member 72. Slides downward, and then the internal stem 74, the external stem 75, and the piston member 72 integrally slide further downward. By this displacement, the piston member 72 opens the gas discharge hole 61e from the closed state by the outer peripheral wall of the upper outer sliding portion 77a (open state). As a result, the compressed gas existing in the gas phase portion inside the container body 2 is released to the outside, and the inside of the container body 2 becomes atmospheric pressure. The arrow A2 indicates the flow of the compressed gas released from the gas phase portion of the container body 2 to the outside. As a result, the compressed gas dissolved at high pressure in the aqueous stock solution 5 becomes supersaturated, so that the compressed gas in an amount up to the saturated dissolved amount at atmospheric pressure is vaporized and a large number of fine bubbles are generated. .. At this time, since a compressed gas with a low solubility in water is used and a specific amount is dissolved in the aqueous stock solution, the bubbles generated are minute and dispersed so that it does not immediately float in the aqueous stock solution and floats. Therefore, the appearance of the aqueous stock solution becomes cloudy due to bubbles. In FIG. 6, the aqueous stock solution in which fine bubbles are generated and dispersed is shown as an aqueous stock solution 5a. Note that, depending on the temperature condition such as a low temperature state, the injected product 1 may be less likely to generate fine bubbles of compressed gas after being switched to the pump injection state. In such a case, the sprayed product 1 may be shaken appropriately. This may promote the generation of fine bubbles.

(Pump injection state)
In the injection product 1 of the present embodiment, as shown in FIG. 6, when the user operates the trigger portion 42i, the piston member 72 slides downward, and the volume of the first space S1 decreases. At this time, the ball 65b sinks due to the downward bias due to the decrease in the volume of the first space S1, and closes the stock solution intake hole 61d. As a result, the undiluted solution (not shown) stored in the first space S1 is pressurized and supplied to the second space S2, passes through the external stem internal passage 75a, and is discharged from the injection hole 43a (see FIG. 1). Is jetted. The jetted aqueous stock solution 5 contains compressed gas dispersed as fine bubbles. Therefore, according to the sprayed product 1 of the present embodiment, many fine compressed gas bubbles can be applied to the coating surface by performing pump spraying.

After that, when the operation of the trigger portion 42i by the user is stopped, the returning operation and the operation of taking the stock solution into the first space S1 are started. That is, by the biasing force of the spring member 73, the internal stem 74, the external stem 75, and the piston member 72 are pushed upward and returned to their original positions, and the communication between the first space S1 and the second space S2 is closed again. It Further, the gas discharge hole 61e is closed again by the outer peripheral wall of the upper outer sliding portion 77a. The upward sliding of the internal stem 74, the piston member 72, and the external stem 75 is stopped by the upper end of the upper outer sliding portion 77a contacting the lower end of the contact leg portion 82 of the contact member 8. ..

Thus, when the inner stem 74, the outer stem 75, and the piston member 72 are integrally pushed up by the spring member 73, the communication between the first space S1 and the second space S2 is closed. Therefore, the ball 65b also moves upward to open a communication place between the stock solution intake hole 61d and the first space S1, and a certain amount of the aqueous stock solution 5 is newly taken from the container body 2 into the first space S1. .. Since the injection product 1 of the present embodiment includes the check valve mechanism 65, the taken-in aqueous stock solution 5 is unlikely to flow back. As a result, the sprayed product 1 is likely to spray an appropriate amount of contents, and a stable effect is easily obtained.

As described above, in the jet product 1 of the present embodiment, the gas discharge hole 61e of the valve mechanism 3 is opened by operating the jet member 4, and the compressed gas in the gas phase portion is discharged to the outside. As a result, the inside of the container body 2 communicates with the atmosphere and becomes atmospheric pressure. As a result, the compressed gas dissolved in the contents is vaporized, and the contents are in a state in which fine bubbles are dispersed. Further, the sprayed product 1 includes a pump mechanism that pressurizes the content. Therefore, the sprayed product 1 can spray the content in which such fine air bubbles are dispersed. In all of these series of operations, it is not essential to attach a special nozzle, for example. In addition, the contents in which fine bubbles are dispersed can give a cleaning effect by the bubbles to the coated surface, for example.

Further, in the injection product 1 of this embodiment, the displacement to the non-injection state, the aerosol injection state and the pump injection state is performed via the piston member 72 housed in the housing 6. Therefore, the size itself of the sprayed product 1 may be small as in the conventional case and is easy to handle. The piston member 72 also cooperates with the operation of the injection member 4. Therefore, the sprayed product 1 is easy to operate.

The method for manufacturing the sprayed product of this embodiment is not particularly limited. As an example, the spray product may be manufactured by filling the stock solution 5 into the container body 2, attaching the valve mechanism 3 to the container body 2 and sealing the container body 2, and filling the container body 2 with a compressed gas.
