Description

[Technical Field]

[0001] The present invention relates to a dispensing product and dispensing member that dispenses contents consisting of a stock liquid and compressed gas to the outside, and more particularly to a dispensing product and dispensing member that retains the compressed gas dissolved in the stock liquid even after dispensing, vaporizing and foaming it on the target object, or further defoaming it, to give the user a fizzy (carbonated) or refreshing sensation. [Background technology]

[0002] Patent Document 1 discloses a discharge product comprising a pressure-resistant container filled with contents consisting of an aqueous concentrate and compressed gas, a valve attached to the pressure-resistant container, and a discharge member attached to the valve, which generates fine bubbles at a high concentration in water (especially hot water), which is the target material. In this discharge product, a reduction unit is provided in the discharge passage of the discharge member to reduce the flow velocity of the contents taken in from the valve.

[0003] The deceleration section is exemplified by an in-passage injection hole formed within the discharge passage and a collision section where the contents injected from the in-passage injection hole collide. The collision with the collision section promotes the vaporization of the compressed gas dissolved in the aqueous concentrate, generating fine bubbles. [Prior art documents] [Patent Documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2017-214138 [Overview of the project] [Problems that the invention aims to solve]

[0005] The dispensing product described in Patent Document 1 generates fine bubbles in the target substance, water or hot water, causing the water or hot water to become cloudy. However, when dispensed into the oral cavity or onto the skin, the irritation from the bubbles was insufficient.

[0006] Furthermore, when carbonated water is poured into a glass, some of the dissolved carbon dioxide vaporizes, but a large amount of carbon dioxide remains in the water. When carbonated water is consumed, it forms bubbles in the mouth and then dissipates, allowing consumers to experience the fizzing sensation (carbonation). However, when carbonated water is dispensed from an aerosol device or pump, it fizzes as it exits the nozzle, and consumers do not experience the carbonation sensation.

[0007] The present invention aims to provide a dispensing product and dispensing component that, when dispensed directly onto an object such as the oral cavity or skin, or when dispensed into a cup and held in the mouth, causes the contents to foam or defoam on the object, thereby providing the user with sufficient stimulation, particularly a fizzy sensation (carbonation) and refreshing feeling similar to that felt when drinking carbonated water. [Means for solving the problem]

[0008] The discharge product 10 of the present invention comprises a discharge container 13, contents N filled in the discharge container 13, and a discharge member 14 attached to the discharge container 13. The discharge container 13 consists of a container body 11 and a valve 12 that seals the container body 11. The contents N consists of a stock solution C and compressed gas P partially dissolved in the stock solution C. The valve 12 comprises a stem 17 with a stem hole 23 that is opened and closed by operation, and a housing 16 that houses the stem 17. A flow rate adjustment section (inlet hole 16c, groove 32e, communication hole 37) with a flow path area narrower than the stem hole 23 is provided between the space inside the discharge container 13 and the stem hole 23, or between the stem hole 23 and the discharge port 36d of the discharge member 14.

[0009] In such a discharge product 10, it is preferable that the discharge member 14 is equipped with a discharge passage (central passage 33b of the stem mounting portion 33, internal space 36f of the nozzle) that guides the contents N discharged from the stem 17 to the discharge port 36d, and that the flow rate adjustment portion (groove 32e, communication hole 37) is provided in the middle of the discharge passage. Furthermore, it is preferable that the cross-sectional area of ​​the flow rate adjustment portion is 0.9 times or less the cross-sectional area of ​​the stem hole 23. Moreover, it is preferable that the flow velocity of the contents N when passing through the stem hole 23 is 1 to 1000 cm / second.

[0010] The discharge member 14 of the present invention is a discharge member 14 that is attached to a discharge container 13 which consists of a container body 11 filled with contents N consisting of a stock liquid C and compressed gas P, and a valve 12 that seals the container body 11. The discharge member 14 comprises a stem mounting portion 33 that is attached to the stem 17 of the valve 12, and a nozzle 36 from which the contents N are discharged to the outside. The discharge member 14 is characterized in that it is provided with a flow rate adjustment portion (groove 32e, communication hole 37) between the stem mounting portion 33 and the discharge port 36d of the nozzle 36, which controls the discharge amount of the contents in a rate-limiting manner.

[0011] In such a discharge member 14, it is preferable that the flow rate adjustment section is equipped with a directional adjustment passage (groove 32e, central passage 33b + communication hole 37) that changes the flow direction of the contents N. It is preferable that the directional adjustment passage is formed in a shape (groove 32e) that guides the contents N in a substantially arc shape. Furthermore, it is preferable that there be an impact wall (front wall 32f, rear end face 38c of the core) downstream of the directional adjustment passage upon which the contents N collide. [Effects of the Invention]

[0012] The discharge product of the present invention has a flow rate adjustment section (rate-limiting section for discharge volume) with a narrower flow path area than the stem hole, located between the space inside the discharge container and the stem hole, or between the stem hole and the discharge port of the discharge member. This allows the contents to pass through the stem hole slowly. As a result, the fluid resistance acting on the contents as they pass through the stem hole is reduced. Furthermore, the compressed gas dissolved in the stock solution is less likely to expand due to the reduced pressure (pressure difference from atmospheric pressure) immediately after the contents pass through the stem hole, suppressing the generation of bubbles from the stock solution and making it easier for bubbles to be generated when it reaches the target object such as the inside of the mouth or skin. Therefore, the user can feel sufficient stimulation, especially a fizzing sensation.

[0013] In such a dispensing product, if the dispensing member is equipped with a dispensing passage that guides the contents dispensed from the stem to the outlet, and the flow rate adjustment section is provided in the middle of the dispensing passage, the flow rate can be adjusted closer to the outlet, which is under atmospheric pressure, thereby suppressing the generation of bubbles immediately after passing through the stem hole and allowing the user to feel a stronger fizzing sensation.

[0014] If the cross-sectional area of ​​the flow rate adjustment section is 0.9 times or less the cross-sectional area of ​​the stem hole, the generation of bubbles immediately after passing through the stem hole can be further suppressed, allowing the user to feel a stronger fizzing sensation.

[0015] When the flow velocity of the contents passing through the stem hole is between 1 and 1000 cm / second, the flow resistance acting on the contents passing through the stem hole is reduced, more effectively suppressing the generation of bubbles immediately after passing through the stem hole. As a result, users can feel the effervescence more strongly.

[0016] The discharge member of the present invention is equipped with a flow rate adjustment section between the stem mounting section and the nozzle outlet, which controls the discharge amount of the contents in a rate-limiting manner. Therefore, it is possible to suppress the generation of air bubbles from the contents before they are introduced into the flow rate adjustment section.

[0017] In such a discharge member, when the flow rate adjustment part includes a direction adjustment passage that changes the flow direction of the content, it is easy to suppress the flow rate of the content. When the direction adjustment passage is formed in a shape that guides the content in a substantially arc shape, it is easy to suppress the flow rate of the content and change the flow direction.

[0018] In such a discharge member, when a collision wall against which the content collides is provided downstream of the direction adjustment passage, the content that has passed through the direction adjustment passage can be made to collide with the collision wall to generate bubbles, giving the user a swishing feeling, and at the same time, splashing due to the content being forcefully discharged from the discharge port can be prevented.

Modes for Carrying Out the Invention

[0020] (Overall) Next, an extrusion product according to one embodiment of the present invention will be described in detail with reference to the drawings. The extrusion product 10 shown in Figure 1 consists of an extrusion container 13 comprising a container body 11 and a valve 12 that seals the container body 11, contents N filled inside the extrusion container 13, and an extrusion member 14 attached to the extrusion container 13. The container body 11 is a bottomed cylindrical shape with an opening 11a at its upper end, and a bead portion 11b is formed around the opening 11a.

[0021] (valve) As shown in Figure 2, the valve 12 consists of a mounting cup 15, a cylindrical housing 16 held in the center of the mounting cup 15, a stem 17 whose lower part is housed within the housing 16 so as to be able to move up and down, a spring 18 that biases the stem 17 upward, and an annular stem rubber 19 held between the upper end of the housing 16 and the mounting cup 15. A dip tube 20 is connected to the lower end of the housing 16.

[0022] The housing 16 is cup-shaped, consisting of a peripheral wall 16a and a bottom wall 16b that closes the lower end of the peripheral wall 16a. A cylindrical portion 16d for attaching the dip tube 20 is formed on the lower surface of the bottom wall 16b. The upper part of the peripheral wall 16a is made thicker so as to be held in the center of the mounting cup 15. Multiple vertical ribs 16a1 extending in the vertical direction are formed on the inner surface of the peripheral wall 16a. The vertical ribs 16a1 are for guiding the stem 17 while ensuring a flow path for the contents N between the lower part of the stem 17 and the ribs 16a1.

[0023] An introduction hole 16c is formed in the center of the bottom wall 16b of the housing 16 for introducing the contents N into the housing 16. The cross-sectional area of ​​the introduction hole 16c is 5 to 50 mm². 2 Preferably, it is 10-40 mm 2It is preferable that this is the case. In the case of the valve 12 shown in Figure 2, the cross-sectional area of ​​the stem hole 23 is made large so that the flow resistance applied to the contents passing through the stem hole 23 is small. When adjusting the flow rate of the contents passing through the stem hole 23 with the inlet hole 16c, it is preferable that the cross-sectional area of ​​the inlet hole 16c be 0.9 times or less, more preferably 0.5 times or less, and especially 0.3 times or less, the cross-sectional area of ​​the stem hole 23. In this case, the inlet hole 16c acts as a flow rate adjustment part. Alternatively, a flow rate adjustment member 41 having a throttling hole 41a corresponding to the inlet hole 16c may be inserted at the lower end of the dip tube 20.

[0024] The stem 17 consists of a thin-walled cylindrical valve stem 21 and a cup-shaped valve dish 22 attached to its lower end. The upper part of the valve stem 21 is made somewhat larger in diameter than the lower part, and a stepped portion 21a is formed between them. The stepped portion 21a engages with the corner of the upper surface of the central hole of the stem rubber 19, causing the inner end of the stem rubber 19 to curve downward in response to the vertical movement of the stem 17. However, it is also possible for the stem 17 to simply slide against the inner circumferential surface of the central hole of the stem rubber 19, so that the stem rubber 19 does not curve.

[0025] The upper part of the valve dish 22 has a gap between it and the lower surface of the valve stem 21, and communicates with the flow path formed by the gap in the longitudinal rib 16a1. A stem hole 23 is formed in the lower part of the valve stem 21, connecting the inside and outside of the valve stem 21. In this embodiment, two stem holes 23 are formed in positions opposite to each other. The stem rubber 19 does not directly open or close the stem holes 23. The stem holes 23 are always open, and in response to the vertical movement of the stem 17, the upper end of the valve dish 22 comes into contact with / separates from the stem rubber 19, indirectly opening and closing the stem holes 23. This makes the cross-sectional area (flow path area) of the stem holes 23 larger than that of a typical stem hole 23 that can be opened and closed by the inner circumferential surface of the stem rubber 19. The total cross-sectional area of ​​the stem holes 23 is 7 to 30 mm². 2 Preferably, it is 10-25 mm 2It is preferable that the cross-sectional area of ​​the stem hole 23 is within the aforementioned range. When the cross-sectional area of ​​the stem hole 23 is within the aforementioned range, the fluid resistance that the contents N experience when passing through the stem hole 23 can be reduced, and the generation of bubbles from the contents N that have passed through the stem hole 23 can be suppressed.

[0026] In the valve 12 configured in this way, under normal conditions, the upper end of the valve plate 22 is in contact with the stem rubber 19, so the contents N are not discharged. When the stem 17 is pushed down, the upper end of the valve plate 22 separates from the stem rubber 19, and the contents that filled the housing 16 (the raw liquid C in which the compressed gas P is dissolved) pass between the inner surface of the housing 16 and the valve plate 22, and are sent to the discharge member 14 through the stem hole 23 and the valve stem 21 of the stem 17.

[0027] (Discharge component) The discharge member 14 shown in Figures 3A to D consists of a main body 30 attached to the valve 12 and a lid 32 connected to the rear upper end of the main body 30 via a hinge 31. The main body 30 consists of a cylindrical stem mounting portion 33 attached to the stem 17, a disc-shaped top plate (see Figure 3C) 34 that extends outward from the upper end of the stem mounting portion 33, a cylindrical cover 35 that hangs down from the periphery of the top plate 34, and a nozzle 36 that protrudes from the front of the top plate 34 (right side in Figure 3) and penetrates the cover 35.

[0028] The lower surface of the stem mounting portion 33 is provided with a fitting hole 33a that engages with the upper part of the stem 17, and this fitting hole 33a communicates with a central passage 33b that passes through the center of the stem mounting portion 33. The center of the top plate 34 is provided with a bottomed cylindrical fitting recess 34a. The inner circumference of the upper part of the fitting recess 34a is formed as a cylindrical surface, and the bottom wall 34b of the fitting recess 34a is provided with a spherically recessed recess 34c.

[0029] The lid 32 consists of a connecting piece 32a extending from the hinge 31 and a fitting projection 32b attached to its tip. The fitting projection 32b consists of a bottomed cylindrical base 32c that fits tightly with the inner circumference of the fitting recess 34a of the main body 30, and a hemispherical convex portion 32d that protrudes downward from the center of the lower surface of the base 32c. A groove 32e extending in an arc shape along the center is formed on the front side of the convex portion 32d.

[0030] As shown in Figure 1, when the lid 32 is fitted and fixed to the body 30, the groove 32e forms a flow path between the protrusion 32d of the lid 32 and the fitting recess 34a of the body 30, and functions as a directional adjustment passage to change the flow direction of the contents N. Furthermore, since the cross-sectional area of ​​the directional adjustment passage is considerably smaller than that of the stem hole 23, it functions not only as a directional adjustment but also as a flow rate adjustment section. The cross-sectional area of ​​the groove 32e is 0.01 to 2 mm². 2 Preferably, it is 0.03 to 1 mm. 2 It is preferable that the cross-sectional area of ​​the groove 32e is 0.9 times or less the cross-sectional area of ​​the stem hole 23, more preferably 0.5 times or less, and especially preferably 0.3 times or less. In this embodiment, since the lid 32 and the body 30 form a narrow flow path, the narrow groove 32e can also be molded with high precision by injection molding or the like.

[0031] In this embodiment, the nozzle 36 has an upper half 36a that is rectangular and a lower half 36b that is cylindrical. The rear end of the internal space 36f of the nozzle 36 communicates with the internal space of the fitting recess 34a. A notch 34f is formed in the front part of the peripheral wall 34d surrounding the fitting recess 34a. The notch 34f is almost completely blocked by the base 32c when the lid 32 is closed, but the internal space of the fitting recess 34a and the internal space 36f of the nozzle 36 communicate through a passage between the base 32c and the bottom wall 34b of the fitting recess 34a. When the lid 32 is closed and fitted onto the main body 30, a front wall 32f is provided at the part facing the upper front side of the groove 32e, which blocks the flow of contents N coming out of the groove 32e (direction adjustment passage, flow rate adjustment section). The tip of the nozzle 36 is a discharge port 36d that opens to the surrounding space, and the tip surface is an inclined surface that slopes forward as it goes down.

[0032] The lower surface of the base 32c of the lid 32 is flat, and as described above, when fitted to the main body 30, a passage for the contents N is formed between it and the upper surface of the bottom wall 34b of the fitting recess 34a of the main body 30. The left and right sides of the passage are restricted by the sides of the inner surface of the nozzle 36. The contents N coming out through the passage collides with the front wall 32f, changing the direction of the flow upward, and the upward-directed flow collides with the flat portion 36g on the upper surface inside the nozzle 36, weakening its momentum. The upper half 36a of the nozzle 36 is made into a rectangular tube shape in order to provide the flat portion 36g. This flat portion 36g also functions as a collision wall.

[0033] As described above, the discharge member 14 is attached to the stem 17 of the valve 12, as shown in Figure 1, and is used as an operating member to open and close the valve 12. That is, when the discharge member 14 is pushed down and the stem 17 is lowered, the valve dish 22 separates from the stem rubber 19 as described above, the contents N enter the valve stem 21 of the stem 17 from the stem hole 23, pass through the central passage 33b of the stem mounting portion 33, and are guided into the nozzle 36 through the curved passage consisting of the groove 32e, and are discharged from the discharge port 36d. At this time, the discharge amount of the contents N is limited by the groove 32e of the discharge member 14 and discharged slowly, so the fluid resistance that the contents N experience when passing through the stem hole 23 is reduced, the generation of bubbles immediately after passing through the stem hole 23 is suppressed, and the dissolved compressed gas can be retained. As a result, the user can strongly feel the fizzing sensation in their mouth or on their skin.

[0034] Next, we will explain examples of the stock solution C and compressed gas P that make up the contents N.

[0035] (Undiluted solution) The stock solution C is a liquid component that is filled into the discharge container 13 together with the compressed gas P. The stock solution C is obtained by adding selected additives and active ingredients to water according to the product's application and purpose. Water is the main solvent of the stock solution C and can dissolve water-soluble additives and active ingredients, and emulsify oily components. In addition, the compressed gas P is dissolved in the stock solution C within the discharge container 13 under a predetermined pressure, and when discharged, the compressed gas P vaporizes into ultrafine bubbles of less than 1 to 1000 nm and fine bubbles of 1 to 1000 μm, and these bubbles are applied to the target object in a dispersed state.

[0036] Examples of water include purified water, deionized water, physiological saline solution, and deep-sea water. The water content is preferably 50% by mass or more, and more preferably 60% by mass or more, in the stock solution. Furthermore, the water content is preferably 99.9% by mass or less, and more preferably 99% by mass or less, in the aqueous stock solution. If the water content is less than 50% by mass, the generation of bubbles will be insufficient, and it will be difficult to obtain a fizzy sensation. On the other hand, if the water content exceeds 99.9% by mass, the amount of active ingredients will be low, and it will be difficult to obtain the effects of the active ingredients.

[0037] Examples of additives include alcohols, oils, surfactants, and thickeners. Alcohols are used to adjust the concentration of compressed gas P dissolved in the stock solution C, thereby adjusting the effervescence and fizziness. The type of alcohol is not particularly limited. For example, monohydric alcohols with 2 to 3 carbon atoms, such as ethanol and isopropanol, are examples. These may be used in combination.

[0038] When alcohol is present, the alcohol content is preferably 1% by mass or more, and more preferably 3% by mass or more, in the undiluted solution. Furthermore, the alcohol content is preferably 40% by mass or less, and more preferably 30% by mass or less. If the alcohol content is less than 1% by mass, the effects of the alcohol will be difficult to obtain. If the alcohol content exceeds 40% by mass, effervescence will be difficult to achieve.

[0039] The oils are used for purposes such as adjusting the foaming properties and making the undiluted solution into an emulsion. The oils are not particularly limited. For example, hydrocarbon oils, ester oils, silicone oils, etc., can be used as oils. These may be used in combination. When an oil is included, the oil content is preferably 0.1% by mass or more, and more preferably 0.5% by mass or more, in the undiluted solution. Furthermore, the oil content is preferably 20% by mass or less, and more preferably 15% by mass or less, in the undiluted solution. If the oil content is less than 0.1% by mass, the effect of the oil is difficult to obtain. On the other hand, if the oil content exceeds 20% by mass, foaming tends to be weak, and it becomes difficult to obtain a fizzy sensation.

[0040] Surfactants are used for purposes such as adjusting foaming properties, enhancing cleaning effects, and solubilizing or emulsifying water-insoluble active ingredients and oils. There are no particular limitations on the type of surfactant. Examples include nonionic surfactants, amphoteric surfactants, amino acid-based surfactants, and silicone-based surfactants. Among these, nonionic surfactants are preferred because they cause less irritation to the skin and mucous membranes.

[0041] The nonionic surfactant is not particularly limited. Examples of nonionic surfactants include polyglycerin fatty acid esters, POE hydrogenated castor oil, POE alkyl ethers, POE sorbitan fatty acid esters, sorbitan fatty acid esters, sucrose fatty acid esters, and POE-POP glycol. These may be used in combination.

[0042] When a surfactant is included, the surfactant content is preferably 0.01% by mass or more, and more preferably 0.1% by mass or more, in the undiluted solution. Furthermore, the surfactant content is preferably 10% by mass or less, and more preferably 7% by mass or less, in the undiluted solution. If the surfactant content is less than 0.01% by mass, the effect of the surfactant is difficult to obtain. On the other hand, if the surfactant content exceeds 10% by mass, it tends to remain on the target object, resulting in a poor user experience and increased susceptibility to irritation from the surfactant.

[0043] Thickening agents are used to increase the viscosity of the stock solution to suppress the force of dispensing, and to suppress and maintain the floating and disappearance of bubbles larger than 1 μm that are generated by compressed gas during dispensing. Examples of thickening agents include methylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, cellulose nanofiber, gum arabic, xanthan gum, guar gum, locust bean gum, gelatin, and carboxyvinyl polymer. These may be used in combination.

[0044] When a thickening agent is included, the amount of the thickening agent is preferably 0.01% by mass or more, and more preferably 0.03% by mass or more, in the undiluted solution. Furthermore, the amount of the thickening agent is preferably 3% by mass or less, and more preferably 1% by mass or less, in the undiluted solution. If the amount of the thickening agent is less than 0.01% by mass, the effect of the thickening agent is not easily obtained. On the other hand, if the amount of the thickening agent exceeds 3% by mass, the viscosity of the undiluted solution becomes too high, making it difficult to pass through the flow rate adjustment section, resulting in poor discharge and a reduced user experience.

[0045] The active ingredients are not particularly limited. For example, active ingredients include humectants such as propylene glycol, 1,3-butylene glycol, glycerin, sorbitol, hyaluronic acid, and urea; cooling agents such as l-menthol and camphor; blood circulation promoters such as nicotinamide, carpronium chloride, diphenhydramine hydrochloride, vitamin E and its derivatives, camphor, capsicum tincture, and minoxidil; sodium saccharin, stevioside, glycyrrhizin, perillartin, thaumatin, palatinose, erythritol, maltitol, and xylitol. Sweeteners such as ethanol, bactericidal or antibacterial agents such as isopropylmethylphenol, chlorohexidine, triclosan, cetylpyridinium chloride, zinc gluconate, zinc citrate, and quaternary ammonium salts, tartar preventive agents such as condensed phosphates and ethane hydroxydiphosphonate, anti-inflammatory agents such as allantoin, tranexamic acid, and dipotassium glycyrrhizinate, enzymes such as dextrose and mutanase, astringents such as sodium chloride and aluminum lactate, hypersensitivity inhibitors such as potassium nitrate, ascorbic acid, tocopherol Vitamins such as methyl esters, extracts of clove, rosemary, scutellaria baicalensis, etc., preservatives such as sodium benzoate, parahydroxybenzoic acid ester, ethylenediaminetetraacetate, benzalkonium chloride, phenoxyethanol, etc., pH adjusters such as citric acid, phosphoric acid, malic acid, lactic acid, etc., Houttuynia cordata extract, Phellodendron amurense extract, Melillolithia erythrorhizon extract, Licorice extract, Peony extract, Luffa gourd extract, Cinchona extract, Sophora flavescens extract, Primrose extract, Rosemary extract, Lavender extract, Lemon extract, Allo Extracts such as cinnamon extract, calamus root extract, eucalyptus extract, sage extract, tea extract, seaweed extract, placenta extract, and silk extract; essential oils such as peppermint, spearmint oil, and peppermint; fruit essences such as lemon and strawberry; l-menthol, limonene, ocimene, cineole, n-decyl alcohol, citronellol, vanillin, α-terpineol, methyl salicylate, thymol; fragrances such as rosemary oil, sage oil, perilla oil, lemon oil, and orange oil; and various pigments.

[0046] When an active ingredient is present, the amount of the active ingredient is preferably 0.01% by mass or more, and more preferably 0.05% by mass or more, in the undiluted solution. Furthermore, the amount of the active ingredient is preferably 10% by mass or less, and more preferably 8% by mass or less, in the undiluted solution. If the amount of the active ingredient is less than 0.01% by mass, the effect of the active ingredient is difficult to obtain sufficiently. On the other hand, if the amount of the active ingredient exceeds 10% by mass, depending on the active ingredient, stability may deteriorate or the feel of use may worsen.

[0047] (Compressed gas) The compressed gas P is filled into the discharge container 13 together with the stock solution C and sealed by the valve 12. In the discharge container 13, the majority of the compressed gas P exists in the gas phase and acts as a pressurizing agent to pressurize the stock solution C and make it dischargeable. The remainder is saturated dissolved in the stock solution C and, when discharged to the outside, becomes bubbles and acts as a foaming agent.

[0048] Examples of compressed gas P include carbon dioxide, nitrous oxide, nitrogen, compressed air, and mixtures thereof. Among these, it is preferable to include carbon dioxide or nitrous oxide, which have high solubility in water. The solubility of the compressed gas is preferably 10 ppm or more, and more preferably 20 ppm or more, at 25°C. Furthermore, the solubility of the compressed gas may be 20,000 ppm or less, and preferably 18,000 ppm or less. If the solubility of the compressed gas is less than 10 ppm, the amount is too low, resulting in insufficient bubble generation when discharged from the discharge container 13 in Figure 1, and a fizzing sensation cannot be obtained. On the other hand, if the solubility of the compressed gas exceeds 20,000 ppm, the discharge force tends to be too strong, and the irritation felt on the mucous membranes becomes too intense.

[0049] In the discharged product 10 shown in Figure 1, the pressure (gauge pressure) inside the discharge container 13, which is filled and sealed with the stock solution C and compressed gas P, is preferably 0.4 MPa or higher, and more preferably 0.5 MPa or higher, at 25°C. Furthermore, the pressure inside the discharge container 13 is preferably 1.0 MPa or lower, and more preferably 0.8 MPa or lower. If the pressure inside the discharge container 13 is lower than 0.4 MPa, the amount of compressed gas P dissolved will be small, resulting in less bubble generation and making it difficult to obtain a fizzy sensation. On the other hand, if the pressure inside the discharge container 13 is higher than 1.0 MPa, the force of the discharged product (contents N) tends to be strong.

[0050] In the discharge product 10 shown in Figure 1, by operating the discharge member 14 to open the stem hole 23 of the valve 12, the contents N stored in the housing 16 are pushed out by the pressure in the discharge container 13 and pass through the stem hole 23. At this time, because the cross-sectional area of ​​the stem hole 23 is increased and the flow rate is adjusted by the groove 32e of the discharge member, the contents N passing through the stem hole 23 flow slowly, the flow resistance acting on the contents N passing through the stem hole 23 is small, the generation of bubbles immediately after passing through the stem hole 23 is suppressed, and the dissolved compressed gas P is easily retained in the contents N. After that, the contents N that have passed through the groove 32e (directional adjustment passage) collide with the front wall 32f and the flat part 36g. Since these collision points are close to the outside (atmospheric pressure), the dissolved compressed gas P vaporizes here and a lot of bubbles are generated.

[0051] The amount of contents N discharged from the discharge port 36d is preferably 0.2 to 4 mL / second per unit time, and more preferably 0.3 to 3 mL / second. The flow velocity of the contents N as it passes through the stem hole 23, calculated from the discharge amount of contents N, is preferably 1 to 1000 cm / second, and more preferably 3 to 800 cm / second. When the flow velocity is 1 to 1000 cm / second, the flow resistance applied to the contents N passing through the stem hole 23 is reduced, and the generation of bubbles immediately after passing through the stem hole 23 is more strongly suppressed. As a result, the user can feel the fizzing sensation more strongly. The flow velocity of the contents N passing through the stem hole 23 can be calculated as "discharge amount per unit time / cross-sectional area of ​​the stem hole".

[0052] The generated bubbles consist of a mixture of ultrafine bubbles (less than 1-1000 nm) and fine bubbles (1-1000 μm), making it easy to obtain the bubble effect by applying the foamed material to the target object. Furthermore, the distance from the impact section (front wall 32f) to the discharge port 36d is short, and the passage (internal space 36f) inside the nozzle is large, so no flow resistance is added to the contents in which bubbles are generated, making it easy to obtain a fizzing sensation.

[0053] (Other dispensing members) The discharge member 14A shown in Figures 4A-B has a central passage 33b passing through the center of the stem mounting portion 33 and the inside of the nozzle 36 connected by a narrow communication hole 37 passing through the center of the nozzle 36. Preferably, the flow area of ​​the communication hole 37 is smaller than the flow area of ​​the valve stem hole, and is preferably 0.9 times or less, more preferably 0.5 times or less, and particularly preferably 0.3 times or less, the cross-sectional area of ​​the stem hole. As a result, the communication hole 37 acts as a flow path adjustment section. The communication hole 37 also exhibits an angle approximately perpendicular to the central passage 33b of the stem mounting portion 33. Therefore, the central passage 33b and the communication hole 37 act as a directional adjustment passage that changes the fluid flow.

[0054] A core body 38, with multiple grooves 38a formed around its periphery, is fitted into the internal space 36f of the nozzle 36. In this embodiment, as shown in Figure 4B, there are four grooves 38a, and the cross-sectional shape of the grooves 38a is approximately fan-shaped. However, the number of grooves 38a and their cross-sectional shape are not limited to these.

[0055] The tip of the core body 38 is provided with a flange 38b that restricts the insertion depth of the core body 38 into the internal space 36f. As a result, a gap 40 with a predetermined distance is formed between the rear end surface 38c of the core body 38 and the surface 39 of the stem mounting portion (so to speak, the bottom surface of the internal space 36f) that the rear end surface 38c faces. The rear end surface 38c then acts as an impact wall (front wall) against which the contents flowing out from the communication hole 37 collide.

[0056] Even in the discharge member 14A configured as described above, it can be attached to the valve 12 of the discharge container 13 in FIG. 1 and used as an operation member. In this discharge member 14A, the content discharged from the stem passes through the central passage 33b, changes direction at a right angle and enters the communication hole 37, is constricted by the communication hole 37, collides with the rear end surface 38c of the core body 38, changes direction radially outward, and further slowly discharges from the opening at the tip of the nozzle 36 (the opening of the groove 38a) through the plurality of grooves 38a. This discharge is a slow discharge such as outflow or dripping rather than ejection.

[0057] The discharge member 14 in FIG. 5 is the same as that in FIG. 1, and the cross-sectional area of the flow rate adjustment part (groove 32e) is preferably 0.9 times or less, and further preferably 0.5 times or less, of the cross-sectional area of the stem hole 23 of the valve 12A in FIG. 5. The cross-sectional area of the stem hole 23 of the valve 12A is preferably 0.05 to 2 mm 2 and more preferably 0.1 to 1.8 mm 2 The cross-sectional area of the introduction hole 16c of the valve 12A is preferably 0.5 to 7 mm 2 and more preferably 0.7 to 5 mm 2 is preferable.

Example

[0058] Next, specific examples will be given to explain the effects compared with the comparative examples.

[0059] [Example 1] The discharge product 10 in FIG. 1 was used as the discharge product of Example 1. The container body 11 is made of thin aluminum and has a filling volume of 128 mL. As the valve, the valve 12 in FIG. 2 was used and crimped to the upper end opening of the container body 11 according to a conventional method. The stem holes 23 are circular and two with an inner diameter of 3.5 mm are formed. The cross-sectional area (flow path area) of the two stem holes 23 is 19.23 mm 2 in total. The inner diameter of the introduction hole 16c of the housing 16 is 6.5 mm, and the cross-sectional area is 33.27 mm 2 is.

[0060] The discharge member 14 shown in Figures 3A-D was used as the discharge member. The groove (flow rate adjustment section) 32e has a width of 0.3 mm and a depth of 0.2 mm, with a cross-sectional area of ​​0.06 mm. 2 The cross-sectional area of ​​the flow rate adjustment section / the cross-sectional area of ​​the stem hole = 0.003. The distance from the outlet of groove 32e to the front wall 32f is 15 mm. The distance from the outlet of groove 32e to the inner surface of the upper wall (flat portion 36g) of nozzle 36 is 2.75 mm.

[0061] The discharge container was filled with 70 g (70 mL) of stock solution C, which consisted of purified water, and 1.9 g of carbon dioxide was added as compressed gas, with a portion of the carbon dioxide being saturated and dissolved in the stock solution. The pressure inside the discharge container at 25°C was 0.6 MPa, and the dissolved amount of carbon dioxide was 13,000 ppm.

[0062] [Example 2] Discharge component groove (flow rate adjustment section) 32e: width 1.0 mm x depth 0.5 mm, cross-sectional area: 0.50 mm 2 Except for the above, the discharge product was manufactured in the same manner as in Example 1, and this became the discharge product of Example 2. The cross-sectional area of ​​the flow rate adjustment section / the cross-sectional area of ​​the stem hole = 0.026.

[0063] [Example 3] The discharge product 10A equipped with valve 12A shown in Figure 5 was used as the discharge product for Example 3. The inner diameter of the stem hole 23 of valve 12A is 0.4 mm, and the cross-sectional area is 0.13 mm². 2 The inner diameter of the introduction hole 16c of the housing 16 is 2.0 mm, and the cross-sectional area is 3.14 mm. 2 The discharge member 14 is the same as the discharge member in Example 1. The container body 11 and contents are the same as in Example 1. The cross-sectional area of ​​the flow rate adjustment section / the cross-sectional area of ​​the stem hole = 0.462.

[0064] [Comparative Example 1] The discharged product was manufactured in the same manner as in Example 3, except that the discharge member 14B shown in Figure 6 was used, and this was the discharged product of Comparative Example 1. The cross-sectional area of ​​the narrowest point S in the discharge passage of the discharge member 14B is 5 mm². 2Therefore, when this is applied to the flow rate adjustment section, the ratio of the cross-sectional area of ​​the flow rate adjustment section to the cross-sectional area of ​​the stem hole is 38.4 times.

[0065] [Verification of effectiveness] 1. Measurement of discharge volume The dispensed products of Examples 1-3 and Comparative Example 1 were immersed in a 25°C constant temperature water bath for 30 minutes to adjust the contents to 25°C. The dispensing mechanism was operated for 5 seconds to measure the dispensing volume (g / 5 seconds), and the dispensing volume per second (mL / second) was calculated from the density of the dispensed contents. The density of the dispensed contents was assumed to be 1 for the calculation. 2. Flow velocity in the stem hole The flow velocity (cm / sec) of the contents as they passed through the stem hole was calculated from the cross-sectional area of ​​the stem hole and the discharge volume (mL / sec). 3. Fizzy sensation The dispensed products of Examples 1-3 and Comparative Example 1 were immersed in a 25°C constant temperature water bath for 30 minutes to adjust the contents to 25°C. The dispensing mechanism was operated to dispense 5g of the contents into a cup, which was then held in the mouth, and the effervescence was evaluated by sensory perception. ◎: The same level of fizziness as commercially available sparkling water. ○: Slightly weaker than commercially available sparkling water, but still provides a sufficient fizz. ×: It's weaker than commercially available sparkling water.

[0066] [Table 1]

[0067] As can be seen from Table 1, the discharged products of Examples 1 to 3, which were equipped with a flow rate adjustment section with a cross-sectional area smaller than the stem hole, produced a fizziness level equivalent to that of carbonated water ("◎") or a slightly weaker but sufficient fizziness level ("〇"). On the other hand, Comparative Example 1, which was not equipped with a flow rate adjustment section with a cross-sectional area smaller than the stem hole, had a weaker fizziness than carbonated water and was unsatisfactory.

[0068] Although preferred embodiments have been described above, the present invention is not limited to these and can be modified without impairing the spirit of the invention. For example, in the discharge member 14 shown in Figures 3A to D, a groove 32e is formed in the convex portion 32d of the lid 32, but a groove may also be formed in the concave portion 34c of the main body 30, or in both. Furthermore, the groove 32e is a downward-convex arc shape, but it may also be an upward-convex arc shape. In addition to being an arc shape around a horizontal axis, it may also be an arc shape around a vertical or diagonal axis. [Explanation of Symbols]
