Description

[Technical Field]

[0001] The present invention relates to a method for producing carbonated fine bubble mixed water, which significantly improves the effects of carbonated spring bathing, such as promoting blood circulation, and also has a carbonated fine bubble effect, and a manufacturing device for easily producing said carbonated fine bubble mixed water. [Background technology]

[0002] Forming a mixture containing bicarbonate (sodium bicarbonate or potassium bicarbonate) and an organic acid into a foaming composition (solid) by tableting or other methods is used in products such as detergents, bath additives, bath water cleaners, and pool disinfectants. These products (solids) have the advantage of dissolving quickly when added to water, generating carbon dioxide gas as a result of the reaction of their ingredients, and at the same time, they enhance the commercial value of the product by providing a pleasant user experience to consumers. In particular, bath additives (sometimes called bath additives) actively utilize the blood circulation-promoting effect of the generated carbon dioxide gas.

[0003] On the other hand, minute air bubbles known as fine bubbles are widely used for purifying turbid water and wastewater, sterilizing domestic water, etc. For example, when fine bubbles are generated in a turbid water treatment tank at a water purification facility, the bubbles can attach to pollutants floating in the turbid water, causing them to float and separate. When fine bubbles are generated in closed bodies of water such as lakes and aquaculture ponds, they can promote the dissolution of oxygen into the water, among other effects.

[0004] Fine bubbles are classified into two types based on their diameter: microbubbles, which are micro-sized (diameter 1 μm or more but less than 100 μm), and ultrafine bubbles, which are nano-sized (less than 1 μm). These are defined in ISO 20480-1 and JIS B 8741-1.

[0005] Conventionally, a fine bubble shower utilizing swirling flow and tap water pressure has been known (see Patent Document 1).

[0006] Also known is a technology that combines a technology for dissolving a carbon dioxide-generating component in hot water with a technology for generating fine bubbles to purify and sterilize the liquid (see, for example, Patent Document 2).

[0007] The technology of Patent Document 1 involves placing a carbon dioxide gas generator, such as various bath additives, inside a gas-liquid mixing device as a gas generator, and then connecting the outlet side of the gas-liquid mixing device to a shower head, so that hot water mixed with bath ingredients and fine bubbles is ejected from the shower head, thereby providing a cleansing effect and health-promoting effects such as promoting blood circulation. On the other hand, there is also known a technique in which carbon dioxide gas bath tablets are placed near the outlet of a shower head (see Patent Documents 3 to 5). [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-229516 [Patent Document 2] Japanese Patent Application Laid-Open No. 2011-194390 [Patent Document 3] Patent No. 4177660 [Patent Document 4] Utility Model Registration No. 3183630 [Patent Document 5] Utility Model Registration No. 3066561 Summary of the Invention [Problem to be solved by the invention]

[0009] However, in the prior art cited in the background art, conventional bath additive ingredients and tablets are rapidly dissolved by the water flow of tap water pressure, and the dissolution duration of carbon dioxide-generating bath additives is extremely short. Furthermore, the bubbles are extremely large, making them unlikely to affect the skin or blood vessels even when they come into contact with the body. In particular, when using a shower with running water, the water ejected from the shower head quickly flows down after contacting the body, resulting in a shorter contact time between the body and the water, and a smaller contact heat capacity and area compared to when immersing in a bathtub. Therefore, the inventors have discovered that in order to obtain the health-promoting effects of the carbon dioxide ingredients, such as promoting blood circulation, the bubbles are too large to maximize contact with the body, and the short dissolution duration of the bath additive tablets is crucial.

[0010] Therefore, the applicant previously filed a patent application (Patent Application No. 2012-236289) with the objective of "providing a microbubble mixed water manufacturing device that can continuously supply carbon dioxide components during normal shower usage, even when microbubble mixed water mixed with carbon dioxide gas components is sprayed in the shower, and that is expected to fully exert health-promoting effects such as promoting blood circulation, by using a carbonated bath tablet component that can be expected to fully exert health-promoting effects such as promoting blood circulation, with the carbon dioxide gas bubbles being micro-sized, resulting in a large amount of contact with the body, and that allows the carbon dioxide components to be instantly absorbed transdermally." As a solution to this problem, the invention of this prior application proposed "a microbubble-mixed water manufacturing device which mixes hot water introduced into a water passage having a microbubble generator located between the hot water inlet and outlet with microbubbles (fine air bubbles) obtained by dissolving carbonated bath tablets contained in the microbubble generator with hot water, and discharges the mixture from the outlet to obtain microbubble-mixed water, characterized in that the carbonated bath tablets contained in the microbubble generator are compression-molded in the presence of bicarbonate, organic acid, and polyethylene glycol to have a diameter and thickness of 7 mm or more, a hardness of a specific value or more, and a pH value in the range of 5.5 to 8.5 immediately after dissolving in hot water."

[0011] According to the invention of this prior application, the following effects can be obtained: "Since the generation of carbon dioxide gas components continues for a long period of time, the contact time between the body and the microbubble-mixed water in which the carbon dioxide gas components are dissolved is extended, making it possible to easily improve health-promoting effects such as promoting blood circulation."

[0012] However, as the inventor continued to research the invention related to this earlier application, he discovered that merely modifying the carbonated bath additives contained in the fine bubble mixed water manufacturing device would result in the carbonated bath additives being exposed to a strong water current and dissolving rapidly in a short period of time, shortening the time that bicarbonate ions are in contact with the body and making it difficult to obtain a sufficient body warming effect. He also discovered that this would result in a shower with a high concentration of bicarbonate ions in the first half and a freshwater shower in the second half, which meant that the tablets had to be replaced with new ones within the same bath time, and the task of opening the shower head to replace the tablets was cumbersome and difficult, as hands could be slippery with detergent, shampoo, etc.

[0013] Based on the above, the inventors are continuing their research into shower equipment that produces fine bubble mixed water containing carbonated bath additive tablets, and that sprays carbon dioxide fine bubble mixed water into the shower. This shower equipment enhances health-promoting effects such as promoting blood circulation, and maintains the effect of allowing users to enjoy a moderately concentrated bicarbonate shower for a long time, while optimizing the dissolution rate of the carbonated bath additive tablets, extending the life of the tablets, and reducing the frequency of replacement of the carbonated bath additives, thereby reducing running costs.

[0014] Therefore, an object of the present invention is to provide a carbonated fine bubble producing device and method that can add carbonated fine bubble generation effects without affecting the shower water discharge configuration of a shower head in use. Furthermore, we provide a carbonated fine bubble mixed water manufacturing device and manufacturing method that can obtain not only microbubbles but also further subdivided ultrafine bubbles as fine bubbles generated by passing hot water through a mesh body, thereby further improving the blood circulation promoting effect, cleansing effect, etc. [Means for solving the problem]

[0015] 1. A bath additive storage section is provided between the connection at the rear end of the hose and the connection at the shower head, in which solid carbonated bath additives are placed in the hot water supply path. In this carbonated fine bubble mixed water producing device, the carbonated bath additive dissolves in hot water sent from a hose to a shower head, generating carbonated fine bubbles, which then mix with the hot water to produce carbonated fine bubble mixed water, which is then showered out from the hot water outlet of the shower head. The bath additive container is separate from the shower head and is detachably connected between the connecting part at the rear end of the hose and the connecting part of the shower head. The bath additive storage section has a connection section that can be connected to a shower head and a hose, Furthermore, the bath additive storage section is fitted with a lid that can open and close the opening for storing carbonated bath additives while maintaining connection to both the shower head and the hose.

Between the connecting part at the rear end of the hose and the connecting part at the shower head, a bath additive storage part is provided to hold solid carbonated bath additives in the hot water supply path.

A method for producing carbonated fine bubble mixed water as described in 5 or 6 above, characterized in that one or more mesh bodies are housed in a mesh body housing section, and the mesh body housing section is integrally formed with the bath additive housing section. [Effects of the Invention]

[0023] According to the invention of claim 1 or claim 5, the bath additive storage section, which is separate from the shower head, is connected between the connection at the rear end of the hose and the connection at the shower head, i.e., it is arranged upstream of the shower head. This allows the shower spray pattern and water discharge volume of an existing shower head in use to remain the same, or, in the case of a shower head with various water discharge modes, without affecting each water discharge mode, and adds the effect of generating carbonated fine bubbles, which enhance health benefits, just upstream of the shower head. In particular, according to the invention shown in claim 1 or claim 5, the fine bubbles generated when hot water passes through the mesh body can be not only microbubbles but also even finer ultrafine bubbles, thereby further improving the effects of promoting blood circulation and cleansing. The degree of division can be appropriately determined depending on the mesh size of the netting material to be disposed and the number of netting materials to be disposed.

[0024] Furthermore, these effects can be applied not only to shower heads that you use on a daily basis, but also to existing shower heads installed in hotels, sports gyms, etc. when you are traveling. Because the bath additive storage compartment maintains its connection to both the shower head and the hose, meaning that carbonated bath additives can be stored simply by opening the lid without separation or disassembly, carbonated bath additives can be quickly and easily replaced or loaded not only before bathing but also while bathing. Therefore, even if you store carbonated bath additives with wet hands while bathing, there is no risk of dropping the shower head on the bathroom floor, preventing breakage of the shower head and damage to the bathroom floor.

[0025] According to the invention shown in claim 2 or claim 6, the pH of the hot water released from the hot water outlet is kept neutral, resulting in the presence of a large amount of bicarbonate ions in the water, which is expected to have a significant effect on promoting blood circulation and cleansing.

[0026] According to the invention shown in claim 3 or claim 7, a mesh body can be arranged at any position on either the upstream or downstream side of the bath additive storage section, or both, so that the degree of fine bubble fragmentation can be set as desired. In other words, since the bath additive storage section and the mesh-like body storage section are separate components, simply by connecting this separate mesh-like body storage section between the connection section of the shower head and the bath additive storage section, or between the connection section of the rear end of the hose and the bath additive storage section, or even between both, the carbonated fine bubbles are further subdivided (carbonated ultrafine bubbles), thereby achieving an even more improved carbonated fine bubble generation effect. Furthermore, if you are not looking for finer, more fragmented carbonated fine bubbles (ultrafine carbonated bubbles) and are happy with normal carbonated fine bubbles, you can easily choose not to connect the mesh-like body housing part. Furthermore, if the bath additive storage section is not arranged between the connection at the rear end of the hose and the connection at the shower head, and only the mesh storage section containing the mesh is arranged, it can be used as a simple fine bubble shower rather than a carbonated fine bubble shower.

[0027] According to the invention as set forth in claim 4 or claim 8, the mesh-like body storage section is integrally formed with the bath additive storage section, so that by simply connecting this integrally formed bath additive storage section and mesh-like body storage section in a state where they are interposed between the connection section at the rear end of the hose and the connection section of the shower head, it is possible to obtain an even more finely divided fine bubble generation effect.

[0028] In the present invention, "hot water" refers to water, or warm or heated water, or a mixture of both. Furthermore, in the present invention, "amount" refers to "mass" unless otherwise specified, "%" refers to "mass %" unless otherwise specified, and "parts" refers to "parts by mass" unless otherwise specified.

DETAILED DESCRIPTION OF THE INVENTION

[0030] The carbonated fine bubble mixed water producing device (hereinafter sometimes simply referred to as the producing device) and the carbonated fine bubble mixed water producing method (hereinafter sometimes simply referred to as the producing method) according to the present invention will be described below based on the examples shown in Figs. 1 to 4.

[0031] The bath additive manufacturing device (1) of the present invention is provided with a bath additive storage section (5) for storing solid carbonated bath additives (4) in the hot and cold water supply path between a connecting section (31) at the rear end of a hose (3) and a connecting section (21) of a shower head (2). The hot water sent from the hose 3 to the shower head 2 dissolves the carbonated bath additives 4, generating carbonated fine bubbles, which are then mixed with the hot water to produce carbonated fine bubble-mixed water, which is then showered out from the hot water outlet 21 of the shower head 2. The bath additive container (5) is separate from the shower head (2) and is detachably connected between the connecting part (3B) at the rear end of the hose (3) and the connecting part (2A) of the shower head (2). The bath additive container 5 has connectors 5A and 5B that can be connected to the shower head 2 and the hose 3, respectively. Furthermore, the bath additive storage section 5 is fitted with a lid 51 that can open and close an opening 52 for storing carbonated bath additives 4 while maintaining connection to both the shower head 2 and the hose 3. The lid 51 is configured to be able to open and close the opening 52 while maintaining connection with the bath additive container 5 without being separated from it. The bath additive storage section 5 is configured to have a width that allows the carbonated bath additives 4 contained therein to roll around when hot and cold water passes through it, A mesh body 6 is disposed on either or both of the upstream and downstream sides of the bath additive storage section 5, and the carbonated fine bubble mixed water is further broken down by passing through this mesh body 6. When the mesh bodies 6 are disposed only on either the upstream side or the downstream side, two or more are disposed on that side, and when they are disposed on both sides, one or more are disposed on each of the upstream side and the downstream side, for a total of two or more, and in either case, the mesh sizes (openings) of the two or more disposed mesh bodies 6 are two or more different types. This technology is mainly composed of the above, and by using this configuration, carbonated fine bubble mixed water that combines the effects of carbonated spring bathing and fine bubble effects can be easily obtained, and health-promoting effects such as cleansing effects and blood circulation promotion can also be expected.

[0032] Of the components of the production device 1 of the present invention, the bath additive container 5 has a configuration as shown in FIG. 2, for example. The bath additive container 5 has a lid 51, which can be slid open from the main body of the bath additive container 5 in a direction perpendicular to the water flow while remaining connected without detaching or separating, exposing an opening 52 through which carbonated bath additives 4 can be stored. With this configuration, the bath additive container 5 can be separated from the shower head 2 and hose 3, and carbonated bath additives 4 can be stored without further disassembly, making it possible to quickly and easily replace or load carbonated bath additives 4, not only before bathing but even during bathing.

[0033] The mesh 6 disposed upstream and / or downstream of the bath additive storage section 5 has a metal or synthetic resin mesh structure with vertical and horizontal meshes, as shown in Fig. 3, and the mesh size (opening) is preferably about 0.5 mm to 1.5 mm, with two or more types (two types in Fig. 3) of different mesh sizes (openings) being used. The two or more types of mesh 6 with different mesh sizes (openings) are preferably arranged in an order in which the mesh size becomes finer from upstream to downstream. It is preferable that the mesh body 6 has its edges reinforced by a frame 61 so that it can maintain its shape even when subjected to the water pressure of hot and cold water.

[0034] In the embodiment shown in Fig. 1, the mesh body 6 is housed in a mesh body housing portion 7 that is separate from the bath additive housing portion 5. The mesh body housing portion 7 has a configuration such as that shown in Fig. 4, for example. The mesh-like body storage section 7 is preferably arranged in a fixed position by inserting the frame body 61 of the mesh-like body 6 between the guide sections 72 formed as ridges on the inner wall. In the embodiment shown in Figure 4, up to five mesh-like bodies 6 can be stored as shown by the imaginary lines, but it is preferable to set the number of guide sections 72 and the number of mesh-like bodies 6 to be stored appropriately depending on various conditions such as the desired size of fine bubbles. The mesh body 6 can be accommodated in the mesh body accommodation portion 7 by removing and attaching the lid 71 .

[0035] In the embodiment shown in Figure 1, a mesh body housing 7 is connected to both the upstream and downstream sides of the bath additive housing 5. Each mesh body housing 7 contains one mesh body 6. With this configuration, the hot water passing through the hose 3 is subdivided by the mesh body 6 housed in the upstream mesh body housing 7, and this subdivided hot water becomes carbonated fine bubble mixed water as it passes through the bath additive housing 5. It is further subdivided as it passes through the mesh body 6 housed in the mesh body housing 7 downstream of the bath additive housing 5, and is then sprayed as a shower from the hot water outlet 21 of the showerhead 2.

[0036] In the embodiment shown in Figure 1, the connections are made in the following order from upstream to downstream: hose 3, mesh body accommodating section 7, bath additive accommodating section 5, mesh body accommodating section 7, and shower head 2. The connection configuration is as follows: connection section 7A of mesh body accommodating section 7, which has a male thread configuration, is connected to connection section 3B of hose 3, which has a female thread configuration; connection section 5A of bath additive accommodating section 5, which has a male thread configuration, is connected to connection section 7B of mesh body accommodating section 7, which has a female thread configuration; connection section 7A of mesh body accommodating section 7, which has a male thread configuration, is connected to connection section 5B of bath additive accommodating section 5, which has a female thread configuration; and connection section 2A of shower head 2, which has a male thread configuration, is connected to connection section 7B of mesh body accommodating section 7, which has a female thread configuration.

[0037] Next, the carbonated bath additive 4 that can be used in the present invention will be described. The carbonated bath additives 4 that can be used in the present invention may be any solid, regardless of their composition. There are no particular limitations on their shape or size, and they may be in the form of tablets, spheres, or granules other than cubic. For example, the most preferred carbonated bath additives 4 are those disclosed in Japanese Patent No. 6268332, previously proposed by the present inventor, and are exemplified below.

[0038] After granulating bicarbonate with polyethylene glycol (hereinafter sometimes referred to as "PEG") or the like, an organic acid (particularly citric acid, succinic acid, malic acid, fumaric acid) or the like is mixed or granulated with PEG, and each of these is mixed under conditions within a certain ratio, and the excipient of the present invention is added and the tablet is formed by compression molding. The pH of the tablet immediately after dissolution is designed to be in the range described below, so that when water penetrates the tablet, it reacts to vigorously, uniformly, and continuously effervescent carbon dioxide gas, and the generated carbon dioxide gas bubbles can be generated as fine micro-sized carbon dioxide gas for a long period of time. The tablet continues to effervescent micro-sized bubbles until it is completely dissolved, and the bubbles are neutralized in water and dissociated into bicarbonate ions before volatilizing into the air, resulting in a high concentration of dissolved bicarbonate ions. The pH of the water is designed to be 5.5 to 9.0, preferably 6.0 to 8.5. In particular, when the pH when the water is discharged from the hot water outlet 21 is in the range of 6.8 to 8.5 as described above, the cleansing effect and health-promoting effects such as promoting blood circulation are maximized.

[0039] Furthermore, since the bicarbonate mixture is a granulated product prepared by coating with PEG using a fluidized bed, the above-mentioned effects, such as a continuous and uniform reaction within the tablet, are greatly exhibited.

[0040] Furthermore, the higher the tablet hardness, 15 kg or more, preferably 25 kg or more, and particularly preferably 30 kg or more, the more continuous and stable the reaction of the chlorine neutralizing compound can be obtained, and it is preferable that the tablet is molded to a high hardness so that the chlorine neutralization reaction inside the tablet can be suppressed and the dissolved part of the tablet can quickly remove chlorine in hot water. The higher the chlorine removal effect, the greater the health benefits, such as improved blood circulation and increased body temperature, even when taking a shower.

[0041] Furthermore, the tablet friability is preferably 10.0 wt% or less, more preferably 5.0 wt% or less, and even more preferably 3.0 wt% or less, so that the chlorine-neutralizing compound can continue to react stably, maximizing the efficiency of the chlorine-neutralizing reaction inside the tablet and also providing health-promoting effects such as promoting blood circulation and increasing body temperature even during showering.

[0042] For the compression molding to produce tablets of the carbonated bath additive 4 preferably used in the present invention, known compression molding machines can be used without any particular restrictions. For example, a hydraulic press, a single-punch tablet press, a rotary tablet press, a briquetting machine, etc. can be used. The size of the punch used in this tablet press, etc., is preferably 7 mm or more in diameter if the punch is circular, and preferably 7 mm or more in diameter if the punch is triangular or rectangular. The same applies to the thickness of the punch. When obtaining circular tablets, the diameter of the tablet is preferably 7 mm or more, more preferably 10 mm or more, and the thickness is also 7 mm or more, preferably 10 mm or more. When obtaining triangular or rectangular tablets, the diameter and thickness are each preferably 7 mm or more, particularly 10 mm or more, when converted to a circular tablet.

[0043] The tablets of carbonated bath additive 4 do not necessarily have to be round with a flat surface, and as long as they are solid objects of 7 mm or more, they can be oval, tablet-shaped, or spherical, with no restrictions on their shape.

[0044] It is preferable to slowly generate micro-sized bubbles in tablets of the above-mentioned hardness and friability and of a certain size or larger, thereby more efficiently dissolving carbon dioxide gas into the bathwater; therefore, the hardness should be 15 kg or more, preferably 25 kg or more, and particularly preferably 35 kg or more, and the friability should be 10.0 wt% or less, preferably 5 wt% or less, and particularly preferably 3 wt% or less, and a diameter and thickness of 10 mm or more are particularly preferred, as this will allow for more effective generation of carbon dioxide gas in the tablet, efficient dissolution of carbon dioxide gas into the water, and finer bubble diameters, making this a preferred carbonated bath additive 4 for use in the present invention.

[0045] After the water is delivered into the shower head 2 by the water production device 1 having the above configuration, the carbonated spring fine bubble mixed water that is shower-discharged from the water jet holes 21 of the shower head 2 preferably has a pH of 6.8 to 8.5. With this configuration, the water discharged from the water jet holes 21 maintains a neutral pH, resulting in a high concentration of bicarbonate ions in the water, which is expected to have a significant effect on promoting blood circulation and cleansing effects.

[0046] The showerhead 2 to which the manufacturing device 1 and manufacturing method of the present invention can be applied may be any known type. Typically, it comprises a hose 3 for supplying hot and cold water, a handle to which the hose 3 is connected, and a head portion integral with the handle and having hot and cold water outlets 21. The handle and head may be integral, or may be formed separately and connected or joined together into a single unit. The head may be connected directly or indirectly to the handle so that its orientation or angle can be adjusted. It may also have various water-spraying modes that allow the user to select the desired water-spraying mode depending on the user's mood or situation. It may also be a showerhead 2 having at least a head portion with hot and cold water outlets 21, i.e., a variety of existing showerheads of different types, shapes, and sizes. This includes showerheads that are commonly used, as well as existing showerheads found in hotels, gyms, and other locations during travel.

[0047] The shower head 2 and hose 3 to which the manufacturing device 1 of the present invention is connected are originally threadedly connected by a connection part 2A of the shower head 2, which is generally a male thread configuration, and a connection part 3B of the hose 3, which is generally a female thread configuration.This threaded connection is removed, and the bath additive storage part 5 and the mesh-like body storage part 7 are connected in between. Furthermore, when connecting the bath additive storage section 5 and mesh-like body storage section 7 of the present invention to the connection section 2A (male thread portion) of an existing shower head 2, if they cannot be screwed together due to differences in the thread diameter or thread pitch of the thread configuration of each connection section, an adjustment connection section can be used.

[0048] With the bath additive manufacturing device 1 of the present invention having the above-mentioned configuration, hot and cold water passing through the hose 3 is broken down as it passes through the mesh member 6 upstream of the bath additive container 5, then passes through the bath additive container 5 to become carbonated fine bubble mixed water (carbonated microbubble mixed water), and passes further downstream through the mesh member 6 to become even finer carbonated fine bubble mixed water (carbonated ultrafine bubble mixed water), thereby further improving the blood circulation promoting effect, cleansing effect, etc. The degree of break down can be appropriately set by changing the size of the mesh of the mesh member 6 and the number of mesh members 6 arranged.

[0049] The present invention has been described above based on the embodiment shown in FIGS. 1 to 4, but the present invention is not limited to the above embodiment and various modifications can be made within the scope of the present invention.

[0050] In the above embodiment, the mesh body 6 is accommodated in the mesh body accommodation section 7, which is located both between the bath additive accommodation section 5 and the shower head 2 and between the bath additive accommodation section 5 and the rear end of the hose 3, i.e., in two locations, one upstream and one downstream of the bath additive accommodation section 5. However, as shown in Figure 5, the mesh body 6 may be located only between the bath additive accommodation section 5 and the rear end of the hose 3, i.e., only on the upstream side, or as shown in Figure 6, between the bath additive accommodation section 5 and the shower head 2, i.e., only on the downstream side. In addition, when only the upstream side or only the downstream side is provided, at least two mesh pieces 6·6 with different mesh sizes (mesh openings) are accommodated in the mesh material accommodation section 7 on only one side. Even when provided on only one side, it is preferable to provide the mesh with the larger mesh size (mesh opening) on ​​the upstream side and the mesh with the smaller mesh opening on the downstream side. In the embodiments shown in Figures 5 and 6, each mesh material accommodation section 7 is configured to accommodate two mesh pieces 6·6 with different mesh sizes (mesh openings).

[0051] Furthermore, the mesh body 6 is not limited to the longitudinal and transverse mesh of the above embodiment shown in Fig. 3, but may also be a plate-like material with a large number of perforated holes as shown in Fig. 7. By using two or more types of perforated holes with different sizes, it is possible to achieve the same effect as two or more types of perforated holes with different mesh sizes (mesh openings).

[0052] Furthermore, in the embodiments shown in Figures 1 and 4 to 6, the bath additive storage section 5 and the mesh-like body storage section 7 are separate structures, but the present invention also includes an embodiment in which the bath additive storage section 5 and the mesh-like body storage section 7 are integrally formed, as shown in Figure 8. In the embodiment shown in Figure 8, the bath additive storage section 5 is arranged on the left side of the drawing and the mesh-like body storage section 7 is arranged on the right side, but the left and right may be reversed, or the bath additive storage section 5 may be arranged in the center and the mesh-like body storage section 7 may be arranged on both the left and right sides of the drawing.

[0053] Furthermore, whether the bath additive storage section 5 and the mesh storage section 7 are integrally constructed or separately constructed, the number of mesh members 6 stored in the mesh storage section 7 can be selected to any number and mesh size (opening).With this configuration, by selecting the number of mesh members 6 and the mesh size (opening), the degree of further fragmentation of the generated carbonated fine bubbles (microbubbles, ultrafine bubbles) can be selectively set.
