Description

The present invention relates to a method for producing carbonated microbubble water that significantly improves the effects of carbonated spring bathing, such as promoting blood circulation, and also has a carbonated microbubble effect, and a manufacturing device that can easily produce said carbonated microbubble water.

Forming a mixture containing bicarbonate (sodium hydrogen carbonate or potassium hydrogen carbonate) and an organic acid by tableting or other methods to produce a foaming composition (solid material) is used in products such as cleaning agents, bath additives, bath water cleaners, and pool disinfectants. These products (solid materials) have the advantage that when added to water, the ingredients react to generate carbon dioxide gas and dissolve quickly, while at the same time providing consumers with a comfortable experience when used, thereby increasing the product value. In particular, bath additives (sometimes called bath salts) actively utilize the blood circulation promoting effect of the generated carbon dioxide gas.

On the other hand, microscopic bubbles with a diameter of, for example, 0.05 mm or less, known as microbubbles, are widely used for purifying turbid water and wastewater, sterilizing water for daily use, etc. For example, when microbubbles are generated in a turbid water treatment tank at a water purification facility, the bubbles can attach to pollutants suspended in the turbid water, causing them to float and separate. When microbubbles are generated in closed water areas such as lakes and aquaculture ponds, they can promote the dissolution of oxygen in the water.

Conventionally, a type of microbubble shower that uses tap water pressure and swirl flow has been known (see Patent Document 1).

There is also a known technology that combines a technology for dissolving carbon dioxide-generating components in hot water with a technology for generating microbubbles to purify and sterilize the liquid (see, for example, Patent Document 2).

The technology of Patent Document 1 is a technology in which a carbon dioxide gas generator such as various bath additives is disposed as a gas generator in a gas-liquid mixing device, and further, the outlet side of the gas-liquid mixing device is connected to a shower head, so that hot water mixed with the bath ingredients and microbubbles is discharged from the shower head, which is expected to have 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).

JP 2008-229516 A JP 2011-194390 A Patent No. 4177660 Utility Model Registration No. 3183630 Utility Model Registration No. 3066561

However, in the known technologies listed in the Background Art section above, conventional bath additive ingredients and tablets are quickly dissolved by the water flow of tap water pressure, and the dissolution duration of carbon dioxide-generating bath additives is extremely short, and the bubbles that form are extremely large in diameter, making it difficult for them to have an effect on the skin or blood vessels even when they come into contact with the body. In particular, when using a shower to pour hot water, the hot water discharged from the shower head flows down quickly after touching the body, so the contact time between the body and the hot water is short compared to when soaking in water in a bathtub, and the contact heat capacity and area are not large. 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 bubble diameter is too large to maximize the probability of contact with the body, and the dissolution duration of the bath additive tablets is short, which is fatal.

The applicant has therefore previously filed a patent application (Patent Application No. 2012-236289) with the objective of providing a microbubble water manufacturing device which "can continuously supply carbon dioxide components during the duration of normal shower use, even when microbubble water containing carbon dioxide gas components is ejected into the shower, and which is expected to fully exert health-enhancing effects such as promoting blood circulation, thanks to a carbon dioxide bath tablet component which has microscopic carbon dioxide gas bubbles that come into contact with the body in large amounts due to their microscopic size, and which allows the carbon dioxide gas component to be absorbed transdermally in an instantaneous manner." As a solution to this problem, the invention of this prior application proposed a microbubble-mixed water manufacturing device that "mixes hot water introduced into a water passage having a microbubble generator provided 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, the device being characterized in that the carbonated bath tablets contained in the microbubble generator are compressed and 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 of 5.5 to 8.5 immediately after dissolving in hot water."

The invention of this prior application has the following advantages: "The generation of carbon dioxide gas components continues for a long period of time, so the contact time between the body and the microbubble-mixed water in which the carbon dioxide gas components are dissolved is extended, making it easy to improve health-promoting effects such as improved blood circulation."

However, the inventors continued to research the invention related to this prior application, and discovered that only the carbonated bath additives contained in the microbubble mixed water manufacturing device would be exposed to a strong water current and dissolve rapidly in a short time, shortening the time that bicarbonate ions are in contact with the body, making it difficult to obtain a sufficient body warming effect. In addition, the first half of the bath would be a shower with a high concentration of bicarbonate, and the second half would be a shower with only fresh water. This meant that the tablets had to be replaced with new ones during one bath time, and the replacement work, which required opening the shower head and changing the tablets, was cumbersome and difficult, as hands would be slippery with detergent, shampoo, etc.

In light of the above, the inventor is continuing to research shower equipment that uses a shower device for producing microbubble-mixed water containing tablet-shaped carbonated bath additives to spray carbon dioxide gas microbubble-mixed water into the shower, and that can optimize the dissolution speed of the tablet-shaped carbonated bath additives, extend the life of the tablets, reduce the frequency of replacement of the carbonated bath additives, and reduce running costs while enhancing health-promoting effects such as promoting blood circulation and maintaining the effect of allowing the user to enjoy a moderate concentration of bicarbonate shower for a long time.

The method for producing carbonated microbubble water described in any one of 12 to 15 above, characterized in that one or more mesh bodies are disposed downstream of the bath additive storage section, and the generated carbonated microbubbles are passed through the mesh bodies to be further broken down.

According to the invention as set forth in claim 1 or claim 12, by connecting the bath additive storage section between the connection part at the rear end of the hose and the connection part of the shower head, i.e., by arranging it upstream of the shower head, it is possible to add the effect of generating carbon dioxide microbubbles just upstream of the shower head without affecting the shower spray form and water discharge volume of the shower head in use, or, in the case of a shower head equipped with various water discharge modes, without affecting each water discharge mode.
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.
Furthermore, by sliding the hose side body part and the shower head side body part of the manufacturing device apart, the opening of the bath additive storage part can be exposed and the carbonated bath additives can be stored, so that the carbonated bath additives can be easily and simply replaced and loaded in a short time not only before bathing but even during bathing.
In particular, because the manufacturing device can store the carbonated bath additives while maintaining the connection to both the shower head and the hose, the hose and the shower head do not become completely separated and become separate. Therefore, even if you store the carbonated bath additives with wet hands while taking a bath, there is no risk of dropping the shower head onto the bathroom floor, and damage to the shower head and the bathroom floor can be prevented.

According to the invention as set forth in claim 2 or claim 13, since the main body of the production device is made up of at least two members, the extremely simple structure makes it difficult for problems of breakage or malfunction to occur.
In particular, because the manufacturing device can store the carbonated bath additives while maintaining the connection to both the shower head and the hose, the hose and the shower head do not become completely separated and become separate. Therefore, even if you store the carbonated bath additives with wet hands while taking a bath, there is no risk of dropping the shower head onto the bathroom floor, and damage to the shower head and the bathroom floor can be prevented.

According to the invention as set forth in claim 3 or claim 14, the main body of the production device is made up of at least three members, and therefore the structure is extremely simple, making problems such as breakage and malfunctions unlikely to occur.
In particular, because the manufacturing device can store the carbonated bath additives while maintaining the connection to both the shower head and the hose, the hose and the shower head do not become completely separated and become separate. Therefore, even if you store the carbonated bath additives with wet hands while taking a bath, there is no risk of dropping the shower head onto the bathroom floor, and damage to the shower head and the bathroom floor can be prevented.

According to the invention shown in claim 4 or claim 15, by locking the locking mechanism, it is possible to prevent the hose side body part and the shower head side body part from sliding apart while the shower is in use, and by unlocking it, they can be easily slid apart. In addition, this locking mechanism can be locked and unlocked very easily and simply by rotating the hose side body part and the shower head side body part.

According to the invention shown in claim 5, the sliding range is a necessary and sufficient range when storing carbonated bath additives in the bath additive storage section, and the hose side main body part connected to the hose and the shower head side main body part connected to the shower head can be prevented from separating. Therefore, when storing new carbonated bath additives during bathing, it is easy to store them even if your hands and the shower head are wet. In particular, it is extremely easy to use because carbonated bath additives can be stored without separating the shower head side and the hose side.

According to the invention shown in claim 6, the hot water sent from the hose does not hit the carbonated bath agent stored in the bath agent storage section directly, but the impact is softened by a detour, so that the carbonated bath agent can be prevented from being rapidly consumed.

According to the invention shown in claim 7, the pH of the hot water discharged from the hot water outlet is kept neutral, resulting in a large amount of bicarbonate ions being present in the water, which is expected to have a significant effect in promoting blood circulation and cleansing effects.

According to the invention shown in claim 8, the dissolution state of the carbonated bath agent contained in the tablet storage section can be easily grasped from the outside at all times.

According to the invention shown in claim 9 or claim 16, the carbonated microbubbles generated in the bath additive storage section are passed through a mesh body arranged downstream thereof, whereby the microbubbles are further broken down into fine carbonated microbubbles (carbonated nanobubbles), which further improves the blood circulation promoting effect and the cleansing effect. The degree of breakup can be appropriately set by the size of the mesh of the mesh body arranged and the number of mesh bodies arranged.

According to the invention shown in claim 10, by connecting the hose between the rear end and the shower head, it is possible to obtain finely divided carbonated microbubbles (carbonated nanobubbles) that have improved blood circulation promoting effects and cleansing effects compared to carbonated microbubbles produced using carbonated bath additives.

According to the invention shown in claim 11, since the bath additive storage section and the mesh-like body storage section are separate structures, by simply connecting this mesh-like body storage section in a state in which it is interposed between the manufacturing device main body and the shower head, the carbonated microbubbles generated in the bath additive storage section become further subdivided carbonated microbubbles (carbonated nanobubbles), thereby obtaining an even more improved carbonated microbubble generation effect.
Furthermore, if normal carbonated microbubbles are sufficient and finer carbonated microbubbles (carbonated nanobubbles) are not required, it is easy to choose not to connect the mesh-like body housing part.
Furthermore, if only a mesh-like material housing section housing the mesh-like material is arranged between the connection at the rear end of the hose and the connection at the shower head, it can be used as a simple microbubble shower rather than a carbonated microbubble shower.

In the present invention, "hot water" refers to water, or warm or heated water, or a mixture of both. In addition, "microbubbles" refers to what are called fine air bubbles. 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.

The carbonated microbubble mixed water manufacturing device (hereinafter, sometimes simply referred to as the manufacturing device) and the carbonated microbubble mixed water manufacturing method (hereinafter, sometimes simply referred to as the manufacturing method) according to the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the manufacturing device 1 is provided with a bath additive storage section 11 that holds solid carbonated bath additives 4 in the hot water flow path, and the hot water sent from a hose 3 to a shower head 2 dissolves the carbonated bath additives 4 stored in the bath additive storage section 11 to generate carbonated microbubbles, which are mixed with the hot water to produce carbonated microbubble-mixed water, which is then released (shower-discharged) from the hot water outlet 21 of the shower head 2. This configuration makes it possible to easily obtain carbonated microbubble-mixed water that combines the effects of a carbonated spring bath and the microbubble effect, and is therefore a technology that can be expected to have health-promoting effects such as cleansing effects and improved blood circulation.

Before describing the present invention in detail, a reference example of the production apparatus and production method of the present invention will be described first.
In the reference example, as shown in FIGS. 2 to 7, a bath additive storage section 11 for storing carbonated bath additives 4 is provided inside a shower head 2.

The shower head 2 comprises a handle portion 22 and a head portion 23 in which the hot and cold water jet holes 21 are provided in a direction perpendicular to the longitudinal direction of the handle portion 22.
The bath additive storage section 11 is provided inside the head section 23, and when the side on which the hot and cold water outlet 21 is provided is the front side of the head section 23, a rear section 24 which is the rear side of the head section 23 can be slid toward the rear, and by sliding this rear section 24 toward the rear, the bath additive storage section 11 can be pulled out from the head section 23 so that the opening 12 of the bath additive storage section 11 is exposed, and the carbonated bath additive 4 can be stored in the bath additive storage section 11 from the exposed opening 12 when pulled out.
The hot and cold water supply configuration is such that a head portion 23 is provided at one end of the handle portion 22 of the shower head 2, and a connection portion to which a hose 3 is connected is provided at the other end, and the hot and cold water supplied from the hose 3 is supplied into the head portion 23 through a flow path provided inside the handle portion 22.

A locking mechanism restricts the sliding movement of the rear portion 24 relative to the head portion 23 so as to prevent the rear portion 24 from inadvertently sliding backward when the shower is in use, and when storing carbonated bath additives 4 in the bath additive storage section 11, the locking mechanism can be released to allow the rear portion 24 to slide backward.
In other words, a locking mechanism that restricts the sliding movement of the rear portion 24 is provided on either or both of the head portion 23 and the rear portion 24, and this locking mechanism is released by rotating the rear portion 24, allowing the rear portion 24 to slide in the rear direction.

As a specific example of the locking mechanism that restricts the sliding movement of the back part 24, as shown in Figures 4 and 5, a locking claw 25 provided on the back part 24 side is rotated in the direction of the arrow X to enter a locking groove 26 provided on the head part 23 side, thereby being locked.

To release the locking mechanism, the rear part 24 is rotated in the direction of arrow Y, which is the opposite direction to arrow X, to move the locking claw part 25 out of the locking groove part 26. This release of the locking mechanism makes it possible to slide the rear part 24 away from the head part 23 in the rear direction indicated by arrow Z.

The sliding range of the back part 23 from the head part 23 is preferably at least to the position where the opening 12 of the bath additive storage part 11 is exposed from the head part 23, as shown in Figures 2 and 3, and at the position where the opening 12 is exposed, the sliding movement is restricted and the pulling out of the back part 24 from the head part 23 stops.

An example of a means for regulating the sliding movement is a configuration in which a concave or convex portion is provided on either the inner portion of the head portion 23 or the outer portion of the bath additive storage portion 11, and a convex or concave portion is provided on the other, so that these are stopped and regulated at the end point of the sliding movement.
In addition, the sliding configuration of the back portion 24 relative to the head portion 23 can be, for example, a configuration in which a guide groove is provided on the inner wall portion of the head portion 23 and a guide member that slides and engages with the guide groove is provided on the outer portion of the bath additive storage portion 11.

The carbonated bath additives 4 contained in the bath additive storage section 11 are sent to the head section 23 through a flow path in the handle section 22 of the shower head 2 via the hose 3, and the hot water sent to the head section 23 enters the bath additive storage section 11 provided within the head section 23 and dissolves the carbonated bath additives 4 contained in the bath additive storage section 11, generating carbonated microbubbles.As shown in Figure 6, it is preferable that the hot water sent to the head section 22 enters the bath additive storage section 11 after making a detour by passing between the inside of the head section 22 and the outside of the bath additive storage section 11.
With this configuration, the hot and cold water sent from the hose 3 does not hit the carbonated bath agent 4 contained in the bath agent storage unit 11 directly, but is instead redirected to soften the impact, preventing a rapid decrease in the carbonated bath agent. By preventing a rapid decrease in the carbonated bath agent 4, the carbonated spring effect can be sustained for a long time.

In order to make it possible to easily grasp the dissolved state of the carbonated bath agent 4 contained in the bath agent storage section 11 from the outside at all times even during shower discharge, it is preferable to provide at least a part of the back section 24 with a window section 24A made of a transparent material, and to configure the interior of the bath agent storage section 11 so that it is possible to visually observe the inside through the window section 24A, which is a part of the transparent material.

The carbonated spring microbubble mixed water discharged from the shower by the manufacturing device 1 having the above configuration preferably has a pH of 6.8 to 8.5 when discharged from the water outlet 21 of the shower head 2. With this configuration, the pH of the water discharged from the water outlet 21 remains neutral, resulting in a large amount of bicarbonate ions being present in the water, which is expected to have a significant effect in promoting blood circulation and cleansing effects.

Next, the carbonated bath additives that can be used in the present invention will be described.
The carbonated bath agent 4 that can be used in the present invention may be any solid, regardless of its composition. There is no particular limitation on the shape or size, and it may be tablet-like, spherical, or granular other than cubic. For example, the most preferably used carbonated bath agent 4 may be the one described in Japanese Patent No. 6268332 previously proposed by the present inventor, and is exemplified below.

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

Furthermore, because the bicarbonate mixture is a granulated product created by coating with PEG using a fluidized bed, the above-mentioned effects are greatly expressed, such as a continuous and uniform reaction in the tablet.

In addition, the tablet hardness is preferably 15 kg or more, more preferably 25 kg or more, and particularly preferably 30 kg or more, so that a continuous and stable 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.

Furthermore, the more the tablet friability is 10.0 wt% or less, particularly preferably 5.0 wt% or less, and even more preferably 3.0 wt% or less, the more continuously and stably the reaction of the chlorine neutralizing compound can be obtained, and not only can the efficiency of the chlorine neutralization reaction inside the tablet be maximized, but health-promoting effects such as improved blood circulation and increased body temperature can be achieved even when taking a shower.

For the compression molding to produce the carbonated bath agent tablets preferably used in the present invention, a known compression molding machine can be used without any particular restrictions, and for example, a hydraulic press, a single shot 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 when the punch is circular, and preferably 7 mm or more in diameter when converted to a circular punch when the punch is triangular or rectangular. The same applies to the thickness of the punch. When obtaining a circular tablet product, 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 a triangular or rectangular tablet is obtained, the diameter and thickness are each preferably 7 mm or more, particularly 10 mm or more, when converted to a circular tablet.

Carbonated bath salt tablets do not necessarily have to be round with a flat surface; as long as they are solid and 7 mm or larger, they can be oval, tablet-shaped, or spherical, with no restrictions on their shape.

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, and to dissolve carbon dioxide gas in bath water more efficiently; therefore, the hardness is 15 kg or more, preferably 25 kg or more, and particularly preferably 35 kg or more, and the friability is 10.0 wt% or less, preferably 5 wt% or less, and particularly preferably 3 wt% or less, and the diameter and thickness are particularly preferably 10 mm or more, so that the generation of carbon dioxide gas in the tablet occurs more effectively, the dissolution of carbon dioxide gas in the water is efficient, and the diameter of the bubbles becomes fine, making this a preferred carbonated bath additive for use in the present invention.

In the above-mentioned reference example, it is preferable to provide one or more mesh bodies downstream of the bath additive container 11, so that the generated carbonated microbubbles pass through the mesh bodies and are further broken down. The mesh bodies are preferably provided between the bath additive container 11 and the hot water outlet 21, that is, inside the hot water outlet 21 on the front side of the head 23.
According to this configuration, the carbonated microbubbles generated in the bath additive container 11 are further broken down into fine carbonated microbubbles (carbonated nanobubbles) by passing them through the mesh body arranged downstream, which further improves the blood circulation promoting effect, cleansing effect, etc. The degree of breakup can be appropriately set by the size of the mesh of the arranged mesh body and the number of arranged mesh bodies.
Furthermore, by providing the mesh body, even if the carbonated bath additives 4 are broken into pieces during dissolution or become small pieces as the dissolution progresses, the fragmented or small pieces of carbonated bath additives 4 can be retained by the mesh body, so that the carbonated bath additives 4 can be dissolved near the bath additive storage section 11 to generate carbonated microbubbles, and the fragmented carbonated bath additives 4 can be prevented from blocking the hot water outlet hole 21.

The mesh can be placed not only downstream of the bath additive container 11 but also upstream. By placing the mesh upstream, it is possible to prevent carbonated bath additive 4 from breaking into pieces during dissolution or from flowing into the hose 3 upstream of the manufacturing device 1.

In the above reference example, the shower head 2, which is the main component of the manufacturing device 1, is configured to have a bath agent storage section 11, but other components, i.e., the diameter, shape, and number of the holes of the hot and cold water outlet 21, the arrangement and configuration of the holes, the material composition, and other components, may be any known components. In general, it has a configuration consisting of a hose 3 through which hot and cold water is supplied, a handle section 22 to which the hose 3 is connected, and a head section 23 that is integral with the handle section 22 and has the hot and cold water outlet 21. The handle section 22 and the head section 23 may be integral, or may be formed separately and connected or joined to be integral, or the head section 23 may be directly or indirectly connected to the handle section 22 so that the direction and angle can be changed, or it may have various water outlet modes so that the desired water outlet mode can be selected depending on the mood or situation, or it may have a configuration that has at least a head section 23 with hot and cold water outlet 21, that is, an existing general shower head 2 having various configurations with different types, shapes, sizes, etc. can be used.

Next, an embodiment of a specific configuration of the production device 1 and the production method of the present invention will be described.
As shown in FIG. 1 and FIGS. 8 to 10, the manufacturing device 1 and manufacturing method of the present invention are in an embodiment in which a bath agent storage section 11 for storing carbonated bath agent 4 is provided separately from the shower head 2.

The characteristic feature of the present invention is that the carbonated microbubble mixed water producing device 1, which is provided with the bath agent storage section 11, is configured separately from the shower head 2 and is detachably connected between the connection part at the rear end of the hose 3 and the connection part of the shower head 2,
The body of the manufacturing device 1 is composed of at least three members: a hose side body 13 that connects to the connection part at the rear end of the hose 3, a shower head side body 14 that connects to the connection part of the shower head 2, and a bath agent storage part 11 provided inside the hose side body 13 and/or the shower head side body 14.
The main configuration is that when either the hose side main body part 13 or the shower head side main body part 14 slides apart relative to the other in the water flow direction, at least a part of the internal bath additive storage part 11 is exposed from the separated part, and an opening 12 is provided in this exposed part for storing the carbonated bath additive 4 in the bath additive storage part 11.
The hose side main body 13 is provided with a hose connection portion connectable to the rear end of the hose 3 , and the shower head side main body 14 is provided with a shower head connection portion 14 A connectable to the shower head 2 .
Furthermore, the hot water supply configuration is as follows: hot water is sent from the hose 3 through the hose connection part 13A connected to the rear end of the hose 3 into the hose side main body part 13; this sent hot water enters the bath additive storage part 11 and dissolves the carbonated bath additives 4 stored in the bath additive storage part 11, generating carbonated microbubbles, which are then mixed with the hot water to become carbonated microbubble mixed water; this carbonated microbubble mixed water passes through the shower head side main body part 14 and the shower head connection part 14A and is sent to the shower head 2 connected to the shower head connection part 14A, and is sprayed out as a shower from the hot water outlet holes 21 of the shower head 2.

It is preferable that the hot water supplied from the hose 3 into the hose side main body 13 is not supplied straight to the bath additive storage section 11, as shown in Figure 9, but rather that the hot water hits the bottom of the bath additive storage section 11 and takes a detour between the inside of the hose side main body 13 and the outside of the bath additive storage section 11 before entering the bath additive storage section 11.
With this configuration, the hot and cold water sent from the hose 3 does not hit the carbonated bath agent 4 contained in the bath agent storage unit 11 directly, but is instead redirected to soften the impact, preventing a rapid decrease in the carbonated bath agent. By preventing a rapid decrease in the carbonated bath agent 4, the carbonated spring effect can be sustained for a long time.

A locking mechanism restricts the sliding movement of either or both of the hose side main body portion 13 and the shower head side main body portion 14 to prevent one from accidentally sliding apart relative to the other when the shower is in use, and when carbonated bath additives 4 are to be stored in the bath additive storage portion 11, the locking mechanism can be released to allow the rear portion 24 to slide in the rearward direction.
In other words, the locking mechanism is released by rotating either the hose side main body part 13 or the shower head side main body part 14 relative to the other about an axis in the water flow direction, making it possible to separate them by sliding movement.

A specific example of a locking mechanism that restricts sliding movement is a configuration in which the locking claw 15 provided on the shower head side main body 14 enters the locking groove 16 provided on the head part 23 side by the rotation described above, thereby locking the mechanism.

To release the locking mechanism, rotate it in the opposite direction to when it is locked, causing the locking claw 15 to move out of the locking groove 16. Releasing this locking mechanism allows the hose side body 13 and the shower head side body 14 to slide apart in the direction of the water flow.

As shown in Figures 8 and 9, the sliding range when the hose side main body part 13 and the shower head side main body part 14 are separated is preferably at least from the separated part to the position where the opening 12 of the bath additive storage part 11 is exposed, and the sliding movement is restricted at the position where the opening 12 is exposed, and the separation stops.

An example of a means for regulating the sliding movement is a configuration in which guide member 17 shown in Figure 10 is attached to the inside of the shower head side main body 14, and the bath additive storage section 11 is attached to the inside of the hose side main body 13, and guide leg portion 17A of guide member 17 is inserted between the inside of the hose side main body 13 and the outside of the bath additive storage section 11, and tip claw portion 17B is hooked onto rim portion 11A of the bath additive storage section 11, thereby regulating the stopping of these at the end point of the sliding movement.
As an example of the sliding structure, the guide leg 17A may slide between the inside of the hose side main body 13 and the outside of the bath agent storage section 11.

In order to make it possible to easily grasp the dissolved state of the carbonated bath additives 4 contained in the bath additives storage section 11 from the outside at all times even while the shower is being discharged, it is preferable to form at least a part of the bath additives storage section 11 and its outer part, the hose side main body part 13 (and the shower head side main body part 14), from a transparent material, so that the inside of the bath additives storage section 11 can be visually observed through the part made of the transparent material.

After the water is delivered into the shower head 2 by the manufacturing device 1 having the above configuration, the carbonated spring microbubble mixed water that is showered out from the water outlet 21 of the shower head 2 preferably has a pH of 6.8 to 8.5. With this configuration, the pH of the water discharged from the water outlet 21 remains neutral, resulting in a large amount of bicarbonate ions being present in the water, which is expected to have a significant effect in promoting blood circulation and cleansing effects.

Although the embodiment of the manufacturing device and manufacturing method of the present invention has been described above with reference to Figures 1 and 8 to 10, the manufacturing device 1 of the present invention is not limited to the shape shown in Figures 8 to 10, and may be a thin-diameter type as shown in Figure 11. In this thin-diameter type manufacturing device 1, the carbonated bath agent 4 stored in the bath agent storage section 11 is oriented such that the diameter direction is aligned with the water flow direction, unlike the manufacturing device 1 shown in Figures 8 to 10, in which the thickness direction of the carbonated bath agent 4 is aligned with the water flow direction.
The configuration of each of the other parts and the actions and functions based on the configuration are the same.

In the embodiment shown in Figures 1 and 8 to 10, the main body of the manufacturing device 1 is composed of at least three members: a hose side main body 13 that connects to a hose 3, a shower head side main body 14 that connects to a shower head 2, and a bath additive container 11. The hose side main body 13 and the shower head side main body 14 are joined together with the bath additive container 11 stored inside. The hose side main body 13 and the shower head side main body 14 can slide apart from each other in the water flow direction while maintaining at least a partial connection. At least a part of the bath additive container 11 inside is exposed from this separated part, and an opening 12 for the bath additive container 11 is provided in this exposed part. However, the present invention is not limited to such a configuration, and the following configurations can also be adopted.

For example, the main body of the manufacturing device 1 has a hose connection portion 13A that connects to the connection portion at the rear end of the hose 3, a shower head connection portion 14A that connects to the connection portion of the shower head 2, and also has a bath additive storage portion 11 inside, and further has a basic configuration that allows the opening 12 for storing carbonated bath additives 4 in the bath additive storage portion 11 to be opened and closed while the manufacturing device 1 maintains its connection to both the shower head 2 and the hose 3.As long as it has such a basic configuration, the present invention also covers a one-component configuration, a two-component configuration, or a four or more component configuration rather than the three-component configuration shown in the above example.
That is, the three components of the hose side main body 13, the shower head side main body 14, and the bath agent storage 11 may each be formed from an independent member, or any two or all of the three may be integrally formed from one member, or any one or two of the three components, or even all of the three components, may each be formed from two or more members.Preferred component configurations include the three-component configuration described in the above example, and a configuration in which the two components of the hose side main body 13 and the shower head side main body 14 are joined together and the bath agent storage 11 is integrally formed inside one or both of these two components.

As for a configuration in which the opening 11 for storing the carbonated bath agent 4 in the bath agent storage unit 11 can be opened and closed while the production device 1 maintains its connection to both the shower head 2 and the hose 3, in the above embodiment, the hose side main body 13 and the shower head side main body 14 are configured so that one slides away from the other while maintaining at least a partial connection, exposing the opening 12 at the separated portion, but for example, if the hose side main body 13 and the shower head side main body 14 are configured as a single member, an openable door member can be provided at any position on either one or both, and when the door member is opened, the opened portion becomes the opening 12. As the door member, for example, a configuration that can be opened while maintaining a partial connection to the main body via a thin portion or a hinge portion can be mentioned.
Even in this configuration, the carbonated bath additives 4 can be stored in the manufacturing device 1 while maintaining its connection to both the shower head 2 and the hose 3, so the hose 3 and the shower head 2 are not completely separated and become separate entities. Therefore, even if the carbonated bath additives 4 are stored with wet hands while taking a bath, there is no risk of dropping the shower head 2 onto the bathroom floor, and damage to the shower head 2 and the bathroom floor can be prevented.

When storing the carbonated bath additives 4, the joint between the hose side main body part 13 and the shower head side main body part 14 does not separate completely, but at least a portion of the connection remains, and one is slid relative to the other to open and close the opening 12 of the bath additive storage part 11.

According to the manufacturing device 1 and manufacturing method of the present invention having the above-mentioned configuration, the hose side main body portion 13 and the shower head side main body portion 14 of the main body of the manufacturing device 1 can be separated by sliding movement to expose the opening 12 of the bath additive storage portion 11, thereby allowing the carbonated bath additives 4 to be stored.Therefore, the carbonated bath additives 4 can be easily and simply replaced and loaded in a short time not only before bathing but even during bathing.
In particular, because the manufacturing device 1 can store the carbonated bath additives 4 while maintaining the connection to both the shower head 2 and the hose 3, the hose 3 and the shower head 2 do not become completely separated and separate. Therefore, even if the carbonated bath additives 4 are stored with wet hands while taking a bath, there is no risk of dropping the shower head 2 onto the bathroom floor, and damage to the shower head 2 and the bathroom floor can be prevented.

In addition, in the manufacturing device 1 and manufacturing method of the present invention, it is preferable to arrange one or more mesh bodies downstream of the bath additive storage section 11 so that the generated carbonated microbubbles pass through the mesh bodies and are further broken down.

According to this configuration, the carbonated microbubbles generated in the bath additive container 11 are further broken down into fine carbonated microbubbles (carbonated nanobubbles) by passing them through the mesh body arranged downstream, which further improves the blood circulation promoting effect, cleansing effect, etc. The degree of breakup can be appropriately set by the size of the mesh of the arranged mesh body and the number of arranged mesh bodies.
Furthermore, by providing the mesh body, even if the carbonated bath additives 4 are broken into pieces during dissolution or become small pieces as the dissolution progresses, the fragmented or small pieces of carbonated bath additives 4 can be retained by the mesh body, so that the carbonated bath additives 4 can be dissolved near the bath additive storage section 11 to generate carbonated microbubbles, and the fragmented carbonated bath additives 4 can be prevented from blocking the hot water outlet hole 21.

The mesh may be arranged such that one or more mesh pieces are provided inside the main body of the production device 1, or one or more mesh pieces are accommodated in a mesh piece accommodation section that is separate from the main body of the production device 1 and detachably connected between the main body of the production device 1 and the shower head 2.

The mesh can be placed not only downstream of the bath additive container 11 but also upstream. By placing the mesh upstream, it is possible to prevent carbonated bath additive 4 from breaking into pieces during dissolution or from flowing into the hose 3 upstream of the manufacturing device 1.

The shower head 2 to which the manufacturing device 1 and manufacturing method of the present invention are applied may be any known type, and generally has a configuration comprising a hose 3 through which hot and cold water is supplied, a handle to which the hose 3 is connected, and a head portion which is integral with the handle portion and has a hot and cold water outlet 21. The handle portion and the head portion may be integral, or may be formed separately and connected or joined to be integral, or the head portion may be connected directly or indirectly to the handle portion so that the direction or angle of the head portion can be changed, or the head portion may have various water outlet modes so that the desired water outlet mode can be selected according to the mood or situation, or may have a configuration comprising at least a head portion having a hot and cold water outlet 21, i.e., an existing general shower head 2 having various configurations with different types, shapes, sizes, etc. can be used. In other words, a shower head that is used on a daily basis, or an existing shower head installed in a hotel or sports gym at a travel destination can be used.

The showerhead 2 and hose 3 to which the production device 1 of the present invention is connected are originally screwed together at the connection part of the showerhead 2, which is generally a male screw configuration, and the connection part of the hose 3, which is generally a female screw configuration, and this screw connection is removed and connected with the production device 1 of the second embodiment interposed between them. Therefore, the showerhead connection part 14A of the production device 1 has a female screw configuration that can be screwed together with the connection part of the showerhead 2, and the hose connection part 13A has a male screw configuration that can be screwed together with the connection part of the hose 3. If the male screw configuration and female screw configuration of the connection part of the showerhead 2 and the connection part of the hose 3 are reversed, the showerhead connection part 14A and the hose connection part 13A will also have a reversed male screw configuration and female screw configuration.
Furthermore, when connecting the manufacturing device 1 of the present invention having the bath additive storage section 11 of the present invention to the connection section (male thread section) of an existing shower head 2, if the shower head connection section 14A (female thread section) of the manufacturing device 1 cannot be screwed in due to differences in thread diameter, thread pitch, etc., an adjustment connection section can be used between the connection section and the shower head connection section 14A.
Furthermore, when connecting the manufacturing device 1 of the present invention to the connection portion (female thread portion) at the rear end of the hose 3, if the hose side connection portion 13A (male thread portion) of the manufacturing device 1 cannot be screwed together due to differences in thread diameter, thread pitch, etc., an adjustment connection portion can be used between the connection portion and the hose connection portion 13A.

The inventors also disclose the results of their research into another invention (the second invention of the present invention) shown below.

[Document name] Specification [Name of invention] Carbonated microbubble mixed water manufacturing device and manufacturing method [Technical field]

The present invention relates to a method for producing carbonated microbubble mixed water that significantly improves the effects of carbonated spring bathing, such as promoting blood circulation, and also has a carbonated microbubble effect, and a manufacturing device for easily obtaining said carbonated microbubble mixed water.
"Background Art"

Forming a mixture containing bicarbonate (sodium hydrogen carbonate or potassium hydrogen carbonate) and an organic acid by tableting or other methods to produce a foaming composition (solid material) is used in products such as cleaning agents, bath additives, bath water cleaners, and pool disinfectants. These products (solid materials) have the advantage that when added to water, the ingredients react to generate carbon dioxide gas and dissolve quickly, while at the same time providing consumers with a comfortable experience when used, thereby increasing the product value. In particular, bath additives (sometimes called bath salts) actively utilize the blood circulation promoting effect of the generated carbon dioxide gas.

Conventionally, a technique has been known in which carbonated bath additives are added to a shower head to obtain carbonated microbubble shower water (see Patent Documents 101 to 103).

The techniques described in Patent Documents 101 to 103 involve setting carbonated bath additives on a shower head, so if there is no shower head to which the carbonated bath additives can be set, it is not possible to enjoy a carbonated microbubble shower using a shower head.
In particular, even if one had the desire to take a carbonated microbubble shower while traveling abroad, hotels and other accommodations did not have facilities that could accommodate carbonated bath additives, so one had to give up the idea.

The inventors have therefore previously proposed a technology that allows users to enjoy a carbonated microbubble shower using only an existing shower head, without having to change to a shower head specifically for carbonated microbubble showers (Patent Documents 104 and 105).

The technologies described in Patent Documents 104 and 105 involve covering an existing general showerhead with an elastic body and/or a mesh body having fine holes, containing carbonated bath additives in the elastic body and/or the mesh body, and generating carbonated microbubbles just outside the showerhead using hot water ejected from the hot water ejection holes of the showerhead, thereby providing a carbonated microbubble shower.

[Problem to be solved by the invention]

As a result of further research into the above-mentioned prior invention, the inventors found that there is a demand for adding the effect of generating carbon dioxide microbubbles while keeping the shower head's shower water discharge configuration unchanged for reasons such as preference for the shower spray shape and water discharge volume of the shower head that is used daily, or the shower head that is used daily has various water discharge modes so that the desired water discharge mode can be selected according to mood or situation.

[Effect of the invention]

According to the invention shown in claim 101 or 106, it is possible to provide a carbonated microbubble production device and production method that can add a carbonated microbubble generation effect without affecting the shower water discharge configuration of a shower head in use.

In particular, by connecting the bath additive storage section and the mesh body between the connection part of the shower head and the connection part of the rear end of the hose, i.e., by arranging them upstream of the shower head, it is possible to add the carbon dioxide microbubble generation effect just upstream of the shower head without affecting the shower spray shape and water discharge volume of the shower head during use, or, in the case of a shower head with various water discharge modes, without affecting each water discharge mode.
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 travel.

According to the invention as set forth in claim 102 or 107, the carbonated microbubbles generated in the bath additive storage section are passed through a mesh body disposed downstream thereof, whereby the carbonated microbubbles are further broken down into fine carbonated microbubbles (carbonated nanobubbles), thereby further improving the hair washing effect, etc. The degree of breakup can be appropriately set by the size of the mesh of the storage mesh body and the number of storage mesh bodies.
Furthermore, since the bath additive storage section and the mesh-like body storage section are integrally constructed, an even more improved microbubble generation effect can be obtained simply by connecting this integral production device between the connection section at the rear end of the hose and the connection section of the shower head.

According to the invention shown in claim 103 or 108, the number of mesh pieces to be accommodated in the mesh piece accommodation section can be set arbitrarily, so that the degree of further fragmentation (nanobubble formation) of the generated carbon dioxide microbubbles can be selectively set.

According to the invention as set forth in claim 104 or 109, the carbonated microbubbles generated in the bath additive storage section are passed through a reticulated body disposed downstream thereof, whereby the carbonated microbubbles are further broken down into fine carbonated microbubbles (carbonated nanobubbles), thereby further improving the hair washing effect, etc. The degree of breakup (nanobubble formation) can be appropriately set by the size of the mesh of the reticulated body to be stored and the number of reticulated bodies stored.
Furthermore, 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, the carbonated microbubbles generated in the bath additive storage section become further subdivided carbonated microbubbles (carbonated nanobubbles), thereby achieving an even more improved carbonated microbubble generation effect.
Furthermore, if normal carbonated microbubbles are sufficient and finer carbonated microbubbles (carbonated nanobubbles) are not required, it is easy to choose not to connect the mesh-like body housing part.
Furthermore, if no bath additive container is provided between the connection at the rear end of the hose and the connection at the shower head, and only a mesh container containing a mesh is provided, the shower can be used simply as a microbubble shower rather than a carbonated microbubble shower.

According to the invention shown in claim 105 or 110, the number of mesh pieces to be accommodated in the mesh piece accommodation section can be set arbitrarily, so that the degree of further fragmentation (nanobubble formation) of the generated carbon dioxide microbubbles can be selectively set.

In the present invention, "hot water" refers to water, or warm or heated water, or a mixture of both. "Microbubbles" refers to what are called fine bubbles. 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.

[Form for carrying out the invention]

The carbonated microbubble mixed water manufacturing device (hereinafter, sometimes simply referred to as the manufacturing device) and the carbonated microbubble mixed water manufacturing method (hereinafter, sometimes simply referred to as the manufacturing method) according to the present invention will be described below with reference to the drawings.

The present invention is a manufacturing device that can easily produce carbonated microbubble mixed water that combines the effects of a carbonated spring bath with the effects of microbubbles, and a manufacturing method for carbonated microbubble mixed water. The technology is expected to have health-promoting effects such as cleansing effects and improved blood circulation by discharging (shower discharge) hot water mixed with carbon dioxide gas components and microbubbles from the hot water outlet holes of the shower head of the manufacturing device.

Moreover, the present invention has the advantage that, whether traveling domestically or abroad, one can easily enjoy carbonated microbubble water mixed with carbonated bath salts simply by applying it to an existing general shower head found in lodging facilities, training gyms, swimming pools, etc. In addition, the manufacturing device can be attached and detached from this existing shower head very easily, as it can be simply connected between the shower head connection and the connection at the rear end of the hose.

In particular, the present invention is a technology that can achieve the effect of generating carbonated microbubbles, i.e., cleansing effects and health-promoting effects such as improved blood circulation, just upstream of the showerhead, without affecting the shower spray pattern and water discharge volume of a variety of existing showerheads that do not have a storage section for carbonated bath additives, particularly a favorite showerhead that is currently in use, or, in the case of a showerhead with various water discharge modes, without affecting each water discharge mode.

Below, an embodiment of the present invention will be described in detail with reference to Figures 12 to 14.

The manufacturing device 1 of the present invention is
Between the connecting part 31 at the rear end of the hose 3 and the connecting part 21 of the shower head 2, a bath additive storage part 11 is disposed for storing a solid carbonated bath additive 4 in the hot water supply path.
The carbonated bath agent 4 dissolves in hot water sent from the hose 3 to the shower head 2, generating carbonated microbubbles, which are mixed with the hot water to generate carbonated microbubble-mixed water, which is then released from the hot water outlet 22 of the shower head 2.
The production device 1 is configured to be detachably connected between a connection part 31 at the rear end of a hose 3 and a connection part 21 of a shower head 2,
One or more (three in this embodiment) mesh bodies 5.5.5 are disposed downstream of the bath additive container 11, and the generated carbon dioxide microbubbles pass through the mesh bodies 5.5.5 to be further broken down.
The main components are as follows.

The manufacturing method of the present invention further comprises the steps of:
Between the connecting part 31 at the rear end of the hose 3 and the connecting part 21 of the shower head 2, a bath additive storage part 11 is disposed for storing a solid carbonated bath additive 4 in the hot water supply path.
The carbonated bath agent 4 is dissolved by hot water sent from a hose 3 to a shower head 2 to generate carbonated microbubbles, which are then mixed with the hot water to generate carbonated microbubble mixed water, which is then showered out from the hot water outlet 22 of the shower head 2.
The bath additive container 11 is disposed in a water passage between the downstream side of the rear end of the hose 3 and the upstream side of the shower head 2,
Between the downstream side of the bath additive container 11 and the upstream side of the shower head 2, a mesh container 12 is provided to house one or more (three in this embodiment) mesh bodies 5.5.5. The carbon dioxide microbubbles generated in the bath additive container 11 are further broken down by passing them through the mesh bodies 5.5.5.
The main components are as follows.

The shower head 2 to which the manufacturing device 1 and manufacturing method of the present invention are applied may be any known type, and generally has a configuration comprising a hose 3 through which hot and cold water is supplied, a handle portion to which the hose 3 is connected, and a head portion which is integral with the handle portion and has hot and cold water outlets 22. However, the handle portion and the head portion are not limited to an integral configuration as shown in this embodiment, and may be formed separately and connected or joined to be integrated, or the head portion may be connected directly or indirectly to the handle portion so that the direction or angle can be changed, or the head portion may have various water outlet modes so that the desired water outlet mode can be selected according to mood or situation, or a configuration comprising at least a head portion with hot and cold water outlets 22, i.e., an existing general shower head 2 having various configurations with different types, shapes, sizes, etc. may be used.

The shower head 2 and hose 3 to which the production device 1 of the present invention is connected are originally screwed together at a connection part 21, which is generally a male thread configuration, and a connection part 31, which is generally a female thread configuration, and this screw connection is removed and connected with the production device 1 of the present invention interposed between them. Therefore, the connected part 13 on the upstream side of the production device 1 has a male thread configuration that can be screwed together with the connection part 31 of the hose 3, and the connected part 14 on the downstream side of the production device 1 has a female thread configuration that can be screwed together with the connection part 21 of the shower head 2. Note that if the male thread configuration and female thread configuration of the connection part 21 and the connection part 31 are reversed, the connected part 13 and the connected part 14 will also have the reversed female thread configuration and male thread configuration.

As shown in Figures 12 and 14, the manufacturing device 1 of the present invention is connected to a mesh-like body storage section 12 arranged downstream of a bath additive storage section 11 in an integral configuration, and three mesh-like bodies 5, 5, 5 are stored in the mesh-like body storage section 12.

A removable lid 15 is screwed to the bath additive storage section 11 in a liquid-tight and airtight manner, and carbonated bath additives 4 can be stored inside by removing and attaching this lid 15. A removable lid 16 is screwed to the mesh body storage section 12 in a liquid-tight and airtight manner, and one or more mesh bodies 5, 5, 5 (three in this embodiment) can be stored inside by removing and attaching this lid 16. Note that the lids 15 and 16 are not limited to screwing and may use other publicly known and used sealing means as long as the bath additive storage section 11 and mesh body storage section 12 can be opened and closed in a liquid-tight and airtight manner.

The mesh body 5 housed in the mesh body housing 12 has a metal or synthetic resin mesh structure with vertical and horizontal meshes as shown in FIG. 13, and the size (mesh size) of the mesh is preferably about 0.5 mm to 1.5 mm. The edges of the mesh body 5 are preferably reinforced by a frame 51 so that the shape can be maintained even when subjected to the water pressure of hot and cold water passed through the hose 3. Furthermore, the mesh body 5 is preferably arranged in a fixed position by inserting the frame 51 between the guides 17, 17 formed in a convex shape on the inner wall of the mesh body housing 12.

When the mesh body 5 is made up of three sheets as in this embodiment shown in Figures 12 and 14, the mesh size (mesh size) of each mesh body 5, 5, 5 may be the same, but it is preferable that the mesh size gradually becomes finer from upstream to downstream.

The hot water sent from the hose 3 enters the bath additive storage section 11, dissolves the carbonated bath additive 4 stored inside to generate carbonated microbubbles, and mixes with the hot water to produce carbonated microbubble mixed water. This carbonated microbubble mixed water then enters the mesh storage section 12, and passes through the meshes 5, 5, 5 stored inside, becoming even finer microbubbles (nanobubbles). This results in a much improved hair washing effect compared to carbonated microbubble mixed water that has only passed through the bath additive storage section 11. In particular, when multiple meshes 5, 5, 5... are arranged, the bubbles are further broken down with each passing mesh, so a shower of extremely fine carbonated microbubbles (nanobubbles) mixed water that has been broken down into multiple stages can be obtained.

The carbonated bath additive 4 that can be used in the present invention may be any solid, regardless of its composition. There are no particular limitations on its shape or size, and it may be tablet-like, spherical, or granular in shape other than cubic. For example, the most preferably used carbonated bath additive 4 is that described in Patent No. 6268332, previously proposed by the present inventor, and is exemplified below.

After granulating bicarbonate with polyethylene glycol (hereinafter sometimes referred to as "PEG"), etc., an organic acid (particularly citric acid, succinic acid, malic acid, fumaric acid) etc. is mixed with PEG or granulated, and each is mixed under conditions within a certain ratio, and the excipient of the present invention is added and a tablet is formed by compression molding. By designing the pH of the tablet immediately after dissolution to be within the following range, when water penetrates the tablet, it reacts to vigorously, uniformly and continuously foam carbon dioxide gas, and the generated carbon dioxide gas bubbles can be generated for a long time as fine carbon dioxide gas of micro size, and the tablet continues to foam micro size bubbles until it is completely dissolved, and the bubbles are neutralized in water before volatilizing into the air, dissociated into bicarbonate ions, and a high concentration of bicarbonate ions is dissolved. The pH of the water is designed to be 5.5 to 9.0, preferably 6.0 to 8.5, and particularly 6.3 to 8.0, so that the effects of cleansing effect and health promotion effects such as blood circulation promotion are maximized.

Furthermore, because the bicarbonate mixture is a granulated product created by coating with PEG using a fluidized bed, the above-mentioned effects are greatly expressed, such as a continuous and uniform reaction in the tablet.

In addition, the tablet hardness is preferably 15 kg or more, more preferably 25 kg or more, and particularly preferably 30 kg or more, so that a continuous and stable 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.

Furthermore, the more the tablet friability is 10.0 wt% or less, particularly preferably 5.0 wt% or less, and even more preferably 3.0 wt% or less, the more continuously and stably the reaction of the chlorine neutralizing compound can be obtained, and not only can the efficiency of the chlorine neutralization reaction inside the tablet be maximized, but health-promoting effects such as improved blood circulation and increased body temperature can be achieved even when taking a shower.

For the compression molding to produce the carbonated bath agent tablets preferably used in the present invention, a known compression molding machine can be used without any particular restrictions, and for example, a hydraulic press, a single shot 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 when the punch is circular, and preferably 7 mm or more in diameter when converted to a circular punch when the punch is triangular or rectangular. The same applies to the thickness of the punch. When obtaining a circular tablet product, 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 a triangular or rectangular tablet is obtained, the diameter and thickness are each preferably 7 mm or more, particularly 10 mm or more, when converted to a circular tablet.

Carbonated bath salt tablets do not necessarily have to be round with a flat surface; as long as they are solid and 7 mm or larger, they can be oval, tablet-shaped, or spherical, with no restrictions on their shape.

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, and to dissolve carbon dioxide gas in bath water more efficiently; therefore, the hardness is 15 kg or more, preferably 25 kg or more, and particularly preferably 35 kg or more, and the friability is 10.0 wt% or less, preferably 5 wt% or less, and particularly preferably 3 wt% or less, and the diameter and thickness are particularly preferably 10 mm or more, so that the generation of carbon dioxide gas in the tablet occurs more effectively, the dissolution of carbon dioxide gas in the water is efficient, and the diameter of the bubbles becomes fine, making this a preferred carbonated bath additive for use in the present invention.

The manufacturing device 1 and manufacturing method of the present invention, which have the above configuration, can add a carbon dioxide microbubble generation effect without affecting the shower water discharge configuration of the shower head in use.

In particular, by connecting the bath agent storage section 11 that stores the carbonated bath agent 4 and the mesh body storage section 12 that stores the mesh body 5 between the connection section 21 of the showerhead 2 and the connection section 31 at the rear end of the hose 3, i.e., by arranging them upstream of the showerhead 2, it is possible to add a carbonated microbubble generation effect just upstream of the showerhead 2 without affecting the shower spray form and water discharge volume of the showerhead 2 during use, or, in the case of a showerhead 2 equipped with various water discharge modes, without affecting each water discharge mode.
Furthermore, these effects are not limited to shower heads 2 that are used on a daily basis, but can also be applied to existing shower heads 2 installed in hotels, sports gyms, and other locations when traveling.
Furthermore, by passing the carbonated microbubbles generated in the bath additive storage section 11 through the mesh body 5 disposed downstream, they are further broken down into fine carbonated microbubbles (carbonated nanobubbles), which further improves the hair washing effect, etc. The degree of fragmentation can be appropriately set by the size of the mesh of the stored mesh body 5 and the number of stored mesh bodies 5. If the number of mesh bodies 5 stored in the mesh body storage section 12 can be arbitrarily set, the degree of further fragmentation (nanobubble formation) of the generated carbonated microbubbles can be selectively set.
Furthermore, in the embodiment shown in Figures 12 to 14, the bath agent storage section 11 and the mesh body storage section 12 are integrally constructed, so that by simply connecting this integrally constructed manufacturing device 1 between the connection section 31 at the rear end of the hose 3 and the connection section 21 of the shower head 2, an even more improved microbubble generation effect can be obtained.

The present invention has been described above based on the embodiments shown in Figures 12 to 14, but the present invention is not limited to the above embodiments and various aspects can be adopted within the scope of the present invention.

When multiple mesh bodies 5 are arranged in the mesh body storage section 12, it is preferable to arrange the mesh bodies 5, 5, 5 having the same mesh size (mesh size) by changing the mesh angle for each mesh body so that the meshes cross without lining up when stacked, as shown in FIG. 15, for example.

It is also preferable to arrange mesh bodies 5, 5 with different mesh sizes (mesh size) as shown in Figure 16.

Furthermore, the mesh body 5 is not limited to a vertical and horizontal mesh, and a plate-shaped material with many fine holes perforated therein as shown in FIG. 17 can also be used. When arranging multiple mesh bodies 5 with such a fine hole configuration, it is preferable to use mesh bodies 5 with different hole diameters.

In addition, in the embodiment shown in Figures 12 to 14 above, the bath agent storage section 11 and the mesh-like body storage section 12 of the manufacturing device 1 were integrally constructed, but the present invention also includes an embodiment in which these two are separate.
18, the mesh-like body housing 12 is separate from the bath additive housing 11 and is detachably connected between the bath additive housing 11 and the connection part 21 of the showerhead 2. With this configuration, simply by connecting the separate mesh-like body housing 12 between the connection part 21 of the showerhead 2 and the bath additive housing 11, the carbonated microbubbles generated in the bath additive housing 11 become further subdivided carbonated microbubbles (carbonated nanobubbles), thereby achieving an even more improved carbonated microbubble generation effect.

In addition, with this configuration, if you are not looking for finer, more fragmented carbonated microbubbles (carbonated nanobubbles) and are happy with normal carbonated microbubbles, you can easily choose not to connect the mesh-like body storage unit 12, i.e., to connect only the bath additive storage unit 11 between the connection unit 21 of the shower head 2 and the connection unit 31 at the rear end of the hose 3.

Furthermore, if the bath additive storage section 11 is not arranged between the connection section 31 at the rear end of the hose 3 and the connection section 21 of the shower head 2, and only the mesh body storage section 12 that stores the mesh body 5 is arranged, it can be used as a simple microbubble shower rather than a carbonated microbubble shower.

Furthermore, the present invention also encompasses the addition of other functional means between the connection portion 31 at the rear end of the hose 3 and the connection portion 21 of the showerhead 2, and the addition of the mesh-like body accommodating portion 12 of the manufacturing device 1 of the present invention, the addition of the bath additive accommodating portion 11, or the addition of both the bath additive accommodating portion 11 and the mesh-like body accommodating portion 12.
Other functional means include, for example, a chlorine removal device, an oxidation-reduction device, a filtration device, an aroma addition device, etc. Furthermore, when the bath additive storage unit 11 is already installed or when a bath additive storage unit made by another company is used, the addition of the net-like body storage unit 12 of the manufacturing device 1 of the present invention is also included in the present invention.

In addition, even in the embodiment shown in FIG. 18 in which the mesh-like body storage section 12 is configured separately from the bath additive storage section 11, the number of mesh-like bodies 5 stored in the mesh-like body storage section 12 can be selected to be any number. With this configuration, the degree of further fragmentation (nanobubble formation) of the generated carbonated microbubbles can be selectively set by setting the number of mesh-like bodies 5 as desired.
