Description

The present invention mainly relates to an oral and oral moisturizer that is useful for maintaining moisture around the throat, oral cavity, and mouth.

There is a desire to keep the humidity around oneself comfortable when using an air conditioner, when the air is dry, such as in winter, and for cold prevention and beauty. In addition, considering the harmful effects of opening the mouth during mouth breathing and sleeping (exposure to dry air in the room, etc.), such as the discomfort of the throat felt when waking up, it is said that the person wants to properly humidify the area around the mouth. I have a request.
In this case, adjustment by humidifying the entire room with a humidifier can be considered, but there are problems such as cases where it is not suitable for use depending on the situation, a surface lacking in convenience, and a concern about mold due to dew condensation.

In this regard, for example, the following techniques exist as a device that easily humidifies only the area around the mouth and maintains moisture.
The "respiratory protective device" described in Patent Document 1 comprises a case and a water-containing material loaded in the case to form a main body. A mounting portion consisting of a pair of left and right elastic arms is provided on the upper surface of the case 4, and the nasal septum is sandwiched between both elastic arms to support the main body portion. Moisture inlets are provided on the left and right sides of the upper surface of the case facing the nostrils.
A part of the exhaled breath is blown from the moisture supply port and touches the water-containing material 6 to promote transpiration. The evaporated water vapor is contained in the inspiration and is sucked into the nasal cavity.
According to this, it is possible to easily obtain the effect of preventing the mucous membrane in the nasal cavity and pharynx from drying out without feeling cramped.

Further, from the direction of preventing mouth breathing and mouth opening during sleep, the "mouth breathing correction tape" described in Patent Document 2 has a sheet portion that covers at least both ends of the lips and an adhesive layer provided on the back surface of the sheet portion. By extending the grip portion without the adhesive layer to the outside of the seat portion, the user grips the grip portion extending outward and the adhesive layer is not provided, and the seat portion is lips. The adhesive layer can be peeled off from the skin without sticking to the fingers, and the peeling operation can be easily performed, so that the adhesive layer can be easily removed at a desired timing.
According to this, it is possible to provide a mouth breathing correction tape that can be immediately removed at a desired timing.

However, the respiratory protective equipment described in Document 1 above is not easy to produce and use, and there is a problem that it is hesitant to use when there is a public eye, and when sleeping or when the nose is stuffy, mouth breathing habits. There was a problem in terms of effectiveness and comfort for users who could not get rid of it.
In addition, the mouth breathing correction tape of Document 2 has inconvenience when considering drinking water, yawning, talking with a third party in the same room, etc., and when the nose is severely stuffy, the habit of mouth breathing For users who could not pull out, there were problems in terms of availability, effectiveness, and comfort.

Therefore, the problem to be solved by the invention is that the oral cavity, which is relatively easy to produce and use, effectively moisturizes the mouth and the like according to the user's situation, and can maintain comfort even when worn. The point is to provide a moisturizer around the mouth.

In order to solve the above problems, the oral cavity / mouth moisturizer, which is the first aspect of the means, does not cover the wearer's nose, but covers the wearer's mouth and allows the exhalation / inhalation by the mouth to pass through. It is characterized in that it is provided with an attachment means for attaching the mouth covering portion to the wearer's face, and a space giving means for causing a space around the wearer's mouth in the mouth covering portion at the time of attachment. And.
The oral and mouth moisturizer has the effect of retaining the moisture contained in the exhaled breath inside the mouth covering portion, and brings moisture to the covered portion and the inner portion thereof. Furthermore, by configuring the mouth covering portion so as not to cover the wearer's nostrils, it is possible to maintain comfort during wearing without interfering with the wearer's nasal breathing.

The second aspect of the oral cavity / mouth moisturizer does not cover the wearer's nose, but covers the wearer's mouth and under the chin to allow exhalation and intake by the mouth to pass through, and the mouth cover. Is provided in a portion below the nose and above the mouth, as an attachment means for attaching the sword to the wearer's face, a means for providing a space in the portion of the mouth covering portion near the wearer's mouth when the mouth is worn, and a portion above the mouth. It is characterized by providing a stabilizing means for stabilizing the position of the mouth covering portion to prevent exposure of the oral cavity.

The oral cavity / mouth moisturizer from the third viewpoint does not cover the wearer's nose, but covers the wearer's mouth and under the chin to allow the exhalation / intake by the mouth to pass through, and the mouth cover portion. The attachment means for attaching the mouth to the face, the allowance giving means for creating a space near the mouth of the wearer of the mouth cover portion at the time of attachment, and the mouth cover portion being pulled under the mouth when the wearer opens the mouth. It is characterized by being provided with a lowering prevention means for preventing the oral cavity from being lowered and exposed.

The oral / oral moisturizer according to the fourth aspect is characterized in that the collection (filtration) efficiency of the mouth covering portion is less than that suitable for use as a mask.

The oral / oral moisturizer according to the fifth aspect is characterized in that the mouth covering portion does not have a layer of a filter produced by the melt blow method.

In the oral cavity / mouth moisturizer of the sixth aspect, the mouth covering portion is composed of two or more layers, and the mouth covering portion is provided with an adhesive portion covering at least the front portion of the wearer's lips. It is a feature.

In the oral cavity / mouth moisturizer according to the seventh aspect, the mouth covering portion is composed of two or more layers having different elasticity, and the space-imparting means includes one or more pleats having a total of two or more creases. The mouth covering portion is characterized in that each of the folds of the pleats is provided with a linear, full-thickness adhesive portion that intersects the folds of the pleats.

The method for producing the oral cavity / oral cavity moisturizer from the eighth viewpoint is to produce an oral cavity / oral cavity moisturizer composed of two or more layers having different elasticity in the mouth covering portion having a step of providing pleats by processing with a blade. In the method, a step of bonding including a line intersecting a line to be a crease of the pleats over all layers of the laminated material to be the mouth covering portion is provided before the step of providing the pleats by processing with the blade. It is characterized by that.

The vertical direction when referred to as "prevention of lowering" refers to the direction when viewed from the wearer, and the front-back direction and the left-right direction also refer to the direction when viewed from the wearer. That is, in an upright wearer, the head direction is upward, the foot direction is downward, the chest side is forward, the back side is backward, the right hand side is right direction, and the left hand side is left direction.
"Relax" refers to the physical allowance created between the wearer's mouth and the mouth covering at least in the anterior-posterior direction.
A "mask" is a woven or knitted natural fiber or non-woven fabric that covers the mouth and nose, and prevents particles such as pollen and dust from entering the body, as well as a cold. A sanitary product that does not fall under the Pharmaceutical Affairs Law and is used for the purpose of suppressing the scattering of sneezing and sneezing droplets.

It is effective and easy to keep the humidity around the mouth, oral cavity, throat, etc. according to the user's situation, it can maintain the comfort when wearing it, it does not make you feel stuffy, and it can be used with high convenience.・ Provide moisturizer around the mouth.
In addition, when the area covered by the mouth covering portion is expanded, the lips, cheeks, nasolabial folds, and the like can be kept moisturized.

It is a front view which showed the method of wearing a moisturizer around the oral cavity / mouth by a wearer. It is the figure which looked at the state immediately after wearing the moisturizer around the oral cavity / mouth of the 1st or 2nd Example, as seen from the side. It is the figure which showed the state which the suction occurs typically. It is a figure which showed typically an example of the process of providing pleats by two blades. It is a figure which showed typically an example of the process of providing pleats by one blade and a step forming means. It is the figure which showed typically the appearance of the displacement and wrinkles in the mouth covering part.

It is a perspective view which shows the whole image of the appearance of the oral cavity / mouth area moisturizer of the second embodiment.

Hereinafter, embodiments for carrying out the invention will be described in detail with reference to the drawings. The invention is not limited to the embodiments described below.
As one aspect of the moisturizer around the mouth, a type that is supposed to be worn mainly at bedtime by an adult male and is not supposed to be reused for washing will be described as a first embodiment.

FIG. 1 is a perspective view showing an overall image of the appearance of the oral and oral moisturizer of the first embodiment.
The mouth covering portion 10 does not cover the wearer's nostrils, but covers at least the wearer's mouth to allow exhalation and inspiration by the mouth to pass through. In this embodiment, in addition to covering the mouth and under the chin, the cheeks, chin, lips, etc. are covered. It is large on the left and right and covers close to the ears, which makes the merit of moisturizing great. As an example, polypropylene, which is a material suitable for shape retention and inner fabric protection, is used for the outer layer 1 of the mouth covering portion 10, and a hydrophilic material (a non-woven fabric that is soft to the touch and appropriately retains moisture) is used for the inner layer 2. Use a different type of polypropylene from the outside, which has strength. In this example, comfort was pursued rather than cost reduction, and a fabric with a hydrophilicity of several percent to a dozen percent increased compared to the same type of fabric with a good feel was adopted. The size is the same on the outside and before and after folding, that is, the entire mouth covering portion is configured to have two layers. (The overlap created by pleats is excluded from the layers.) There are only these two layers.

As an attachment means for attaching the mouth covering portion 10 to the wearer's face, polypropylene ear hooks 3 having appropriate elasticity were provided at the left and right ends of the mouth covering portion. When attaching the ear hook, the ear hook is made wider to reduce the burden on the skin (rubber marks, etc.) and to be attached so that it can be removed even with a relatively weak force. The moisturizer around the mouth and mouth of this example is used for a long time during sleep, but it shifts due to its own movement or the movement of the comforter, etc., and it does not cover the mouth or covers the nose unintentionally. This is because it is more desirable that the person comes off without disturbing a good night's sleep, rather than having the person fall asleep.

The pleats 4 designed so that the length of the mouth covering portion 10 in the vertical direction can be appropriately extended as a means for providing a space around the mouth of the wearer in the mouth covering portion 10 at the time of wearing, and the mouth covering portion. A kamaboko-shaped adhesive portion 5 that looks like a pinched portion is provided at a portion of 10 that should come below the wearer's nose and above the mouth. These also serve as a lowering prevention means for preventing the mouth covering portion 10 from being pulled down under the chin and exposing the mouth when the wearer opens the mouth. Further, the adhesive portion 5 is provided in a portion below the nose and above the mouth, and functions as a stabilizing means for stabilizing the position of the mouth covering portion 10 to prevent the exposure of the mouth and the covering of the nostrils.

FIG. 2 is a front view showing a state before welding is performed on the central portions of the upper and lower ends to provide the adhesive portion in the manufacturing process of the oral and oral moisturizer of the first embodiment.
Although the manufacturing processes are ordered in the first embodiment, the second embodiment, etc. for convenience of explanation, the manufacturing procedures do not necessarily have to be in the same order as in the examples. It is possible to take appropriate measures such as making the process in which welding occurs as a series and making it efficient, and arranging the process so as to match the existing manufacturing equipment.
The non-woven fabric to be formed as the outer layer and the non-woven fabric to be formed as the inner layer are overlapped to form the mouth covering portion 10, a crease to be formed as pleats 4 is made, and the non-woven fabric to be used as the mouth covering portion is cut to a size suitable for the mouth covering portion 10. The upper, lower, left and right ends of the above were fixed by welding, and the ear hook 3 was attached by welding, and a star-shaped mark 6 was attached at a predetermined position.

The mouth covering portion 10 should at least cover the mouth to allow exhalation and inspiration from the mouth to pass through, but in this embodiment, the mouth covering portion 10 covers not only the mouth but also the cheeks, chin, and under the chin. Configured. Considering the average face size of the expected wearer so that the cheeks of the assumed wearer (adult male in this example) can be covered as much as possible, it should be as long as possible and the upper end. Was constructed in a U-shaped curve along the wearer's cheekbone. The adjustment of the moisturizing range (especially important when the assumed wearer is an adult woman) and the direction of the pulling force of the ear hook 3 to the ear are taken into consideration. In addition, by using a mouth cover that has less skin stress than the ear hook and is less likely to leave marks, the ear hook is made as short as possible, and the start line of the ear hook is on the edge of the face, and the pressure is applied to the cheek bones as much as possible. It is designed to ride on. Furthermore, the large area of the mouth covering portion tends to prevent slippage.
The position, size, and number of the pleats 4 were adjusted so as to be suitable for the actions and effects described later.

FIG. 3 is a front view showing a state after welding is performed on the central portions of the upper and lower ends to provide the adhesive portion in the manufacturing process of the oral and mouth moisturizer of the embodiment.
When the state shown in FIG. 2 was reached, the mouth covering portion 10 was folded at the center in the left-right direction. Subsequently, a semi-cylindrical adhesive portion 5 was provided on the upper end of the central portion by welding (heat adhesion) from above the fold. Similarly, an adhesive portion is also provided at the lower end to form the lower end adhesive portion 7. As a result, the degree of adhesion under the chin can be made appropriate, which contributes to the prevention of upward displacement of the mouth covering portion 10 and the prevention of gaps in the chin portion.
The adhesive part 5 is a semi-cylindrical type, but this is because the part that touches the wearer's skin is rounded and the opposite side can hit the wearer's nasal septum, so even if it hits by not welding it. This type is used to prevent the horns from sticking.

The adhesive portion 5 works together with the pleats 4 and serves as a means for imparting a margin in the portion around the mouth of the wearer in the mouth covering portion 10 when the mouth covering portion 10 is attached. The width of the central part of the mouth covering part becomes relatively long due to the relative shortening of the pleats 4, and the vertical width of the central part of the mouth covering part 10 is relatively long due to the extension of the pleats 4. (Because the vertical width of the left and right ends is welded so as not to stretch the pleats 4), each becomes a source of space, and the vertical line created by the adhesive part 5 is from the skin of the lower part of the nose. Also works to be forward. The pleats 4 also have an arch effect. In addition, an arch effect can be expected from the vertical line generated from the bonded portion 5.

The wearer's mouth has a forward protrusion on the lips, but if the mouth cover is designed to protrude forward beyond this, there will be more space around the mouth, and even the mouth. Prevents the inside of the mouth cover from entering or touching the mouth when the mouth is opened. It has the effect of making it difficult for inconveniences such as getting inside due to gravity or suction when opening the mouth, touching acne around the mouth, and getting stuffy.
This effect is more important, especially when in a sleeping position.
Next, it will be described that the mouth covering portion is not displaced, particularly, the mouth is not displaced upward to cover the nostrils, and the mouth is not displaced downward to expose the mouth.

In the embodiment, the adhesive portion 5 can be provided as a stabilizing means provided in a portion below the nose and above the mouth to stabilize the position of the mouth covering portion and prevent the mouth from being exposed. In addition, as a configuration for this purpose, for example, a urethane cushion can be used to prevent the displacement (the displacement can be absorbed by the inclination of the cushion, etc.). In addition, sticking to the face with adhesive tape is also conceivable.

Further, in the embodiment, an adhesive portion 5 is provided as a lowering prevention means for preventing the mouth covering portion from being pulled down by the wearer to open the mouth and exposing the mouth. It can be caught on the lips, and the space around the mouth can be utilized, and the extension of the pleats 4 in further development can be utilized. Although it depends on the design of other parts and the size of the wearer's face, the design of the example such as three pleats is sufficient for natural mouth opening during sleep and conversation, and even large mouth opening such as yawning. It can withstand once or twice without position correction. In addition, as a configuration for this purpose, for example, a relatively large mouth covering portion 10 as described later is designed, and its frictional force and adsorption force (particularly moisture inside the mouth covering portion) are designed. It is also conceivable to use when the above is sufficient or when a material having an adsorptive power is used).

The mark on the lower left of the mouth cover (lower left when viewed from the wearer as described above, lower right for those who view the drawing) is provided by welding to identify the orientation of the oral and oral moisturizer to the user. This is a device to make it easier to do. When this configuration is adopted, it is possible to prevent the user from worrying about the orientation of the attachment by displaying in the product description that the mark is attached so that the mark comes to the lower left when viewed from oneself.
In addition, an ear hook 4 was attached as a means of attaching to the face. It is wide, and by making the surface in contact with the face wide with a flat type, stress is reduced, it is hard to leave marks, and it is devised to reduce discomfort due to strain on the ears.

The material of the mouth covering portion 10 is not limited as long as it has a necessary action such as gauze instead of the non-woven fabric. It is not limited to the mouth covering part, but it is also possible to use polyurethane or the like as the material to be selected, or to provide a layer of another material on the outside for the design.
Also, the area under the chin is not always covered. If it is not covered, it will be less necessary to worry about the displacement caused by opening the mouth, but the range of effects such as moisturizing will be narrowed. Conversely, variations that cover dismissals, clavicle, forehead, etc. in some cases are also conceivable.
For example, a type in which the lower part covers up to the chin and the upper part has a mouth covering part 10 up to the height of the nose (around the cheekbone), and the nose part (entire nose or nostril part) is cut out, or the upper part is cut out. Further, it is extended to the forehead part, and the eye part is cut out in addition to the nose part. If the covering range is expanded in this way, the ease of wearing may be reduced, but the moisturizing effect of the wearer is enhanced, and the frictional force of the mouth covering portion 10 also enhances the effect of preventing slippage.

The mouth covering portion 10 has a moisturizing effect due to self-breathing, and can also be expected to have an effect of retaining water secreted from the skin, sweat glands, etc. with the inner cloth. It also contributes to maintaining the moisture provided by the lotion or the like in good condition without being exposed to the dry air in the room. In addition, by designing it with high breathability as described later, it can be used without interfering with secretion from sweat glands and the like (so-called cutaneous respiration in the beauty industry).

In addition to the inner fabric used in this example, various variations can be considered, and with regard to consideration for hydrophilicity, it is also possible to use water, lotion, etc. that have been soaked inside in advance. It is conceivable that a layer made of a hydrophilic material is provided only partially on the inside of the non-woven fabric layer provided on the outside, or a pocket is provided on the inside and a small piece made of the hydrophilic material is put therein. It is also conceivable to soak the small pieces with lotion, fragrance, etc. in advance. Good use of water other than exhaled water is very effective in situations where breathing is centered on the nose but the mouth is open.

As for the inner fabric, the touch is also very important, so for example, it is conceivable to use a super soft fabric with less skin stress. In addition, it is possible to use towel cloth to make it possible to reuse the laundry, or to use a material that emphasizes cost.
As another means of providing room, a more overall three-dimensional structure (a three-dimensional structure including the mouth covering portion 10 in the front-rear direction, a cushion is arranged on all or a part of the end portion of the mouth covering portion 10). (For example, the mouth covering part 10 is relatively hard so that the cup is put on the mouth), or the part that hits the circumference of the mouth, even if it is not the end, is covered with a polyurethane cushion or the like in a ring shape. Be done. It is also conceivable that the inside of the mouth covering part does not touch the mouth and lips at all, and even if there is no such direct contact, it still covers the mouth. .. In addition, when using a polyurethane cushion, it is desirable that it does not interfere with nasal breathing. Of course, it is desirable to avoid not only the design related to the provision of space but also the design that may hinder nasal breathing (for example, the design that the lower part of the nose of the mouth covering part becomes extremely thick). In short, it is desirable to avoid designs that block the nostrils.
You can also use a wire and use it as an arch under the nose or in the mouth.

Further, the adhesive portion 5 may be formed into a crescent moon, a circle, an ellipse, a peanut shape, a fan shape, or the like as appropriate.
In order to prevent irritation to the nasal septum at the time of welding the upper end after cutting the mouth covering portion 10, it is conceivable to leave the lower part of the nose unwelded, to make the welding modest, or to detour downward. Instead of the ear hook 3, for example, it is possible to use an overhead method such as connecting two strings or a flexible material with the vertical width of the mouth cover extended at the back of the head. , A means such as a band that can be adjusted to a preferable length according to the wearer may be provided.
The mark for identifying the orientation is not an indispensable configuration. Moreover, you may make another distinction. For example, it may be color-coded.

FIG. 4 is a front view showing a method in which the wearer wears the oral and oral moisturizer of the embodiment.
The wearer sets the mouth covering portion 10 so as not to cover the nose, attaches it with the ear hook 3, and performs fitting under the chin while appropriately extending the pleats 4.
As explained so far, the inventor has developed the shape of the oral and oral moisturizer to the extent that it can be implemented, but further improved the breathability, etc. in consideration of the comfort of the wearer. ..
Specifically, first, the material and thickness of the non-woven fabric to be appropriately touched and hydrophilic to be adopted inside the mouth covering portion (backward side) are determined, and then the mouth covering portion containing the hydrophilic non-woven fabric is contained. The overall breathability was adjusted according to the layer structure, material used, and thickness. The data is as follows.

The air permeability of the oral and oral moisturizer in this case is 225.3 cubic centimeters / (square centimeter · s) as measured by the JIS L 1096A method.
The air permeability of the comparison target is 19.8 cubic centimeters / (square centimeter · s) as measured by the JIS L 1096A method.
The subject of comparison of breathability with the oral and oral moisturizer in this case is the mask manufactured and sold by the applicant.

Here, a mask is defined by the Japan Sanitary Materials Industry Association as "a woven or knitted fabric of natural fibers or chemical fibers or a non-woven fabric as the main body material, and has a shape that covers the mouth and nose, and pollen. A hygienic product that does not fall under the Pharmaceutical Affairs Law and is used for the purpose of suppressing the invasion of particles such as dust into the body and the scattering of coughs such as colds and sneezing droplets.
In this respect, the oral and oral moisturizer does not cover the nose and is not a mask because of its purpose of use. Furthermore, the masks to be compared and other masks generally provided are layers for appropriate collection (filtration) efficiency (filter layer, non-woven fabric produced by the melt blow method, in which the outer layer and the inner layer are used. It is often provided between them. It is the liver of the mask, and it is this layer that is adjusted according to the collection target), so it is not misunderstood that the wearer can also use it as a mask. Indicate in the product description that it is not a mask or that it is used for moisturizing.

When manufacturing a mask, the layer that serves as a filter is important.
Gauze or the like may be used for the filter layer, but a non-woven fabric produced by the melt blow method is generally used for the filter layer from the viewpoint of easily manufacturing a disposable mask in large quantities.
The mask is designed according to the filtering target such as pollen, virus, fine particulate matter, etc. as a whole and the collection rate is inspected, but the decisive factor is still the filter layer.

And, if you try to improve the filter performance, there is an influence of other designs, but in principle, the air permeability will be sacrificed.
The degree of collection (filtration) efficiency can be measured by a test such as PFE, and the mask used as a comparison target in the air permeability test also exceeds 99% on average in the PFE test. Attempts have been made to propose that the numerical value in the test exceeds 99% as a standard for "masks", but it seems that it has not been established as of the filing date. However, as of the market awareness of the mask industry as of the filing date, there is a recognition that if it does not exceed 99%, it is not suitable for selling as a mask that meets the definition and purpose. (99% or more in the PFE test for viruses and 99% or more in the BFE test for pollen.)

The background behind the development of such breathability adjustment is as follows. That is, the mask may be worn and used for the purpose of moisturizing the mask together with or deviating from the original purpose of use of the mask. However, if you use it in this way, you may feel suffocated and stop wearing it, or you may unknowingly remove it, or you may tend to breathe through your mouth while wearing it, and if you continue for a long time, you may get into the habit of mouth breathing. It is possible that there is no such thing. This is because we wanted to provide a moisturizer for the oral cavity and mouth that avoids the harmful effects.
Of course, since the mask also covers the nose, it is considered that the humidity effect inside the mask can be utilized for exhalation and inspiration from the nose. However, since breathing through the nose can obtain a certain degree of humidifying effect in exhalation without using a tool such as a mask, there is little need to simply cover the nostrils in terms of humidity. (The air sucked from the nose is added with appropriate humidity and temperature, and is taken in with the filter effect of nose hair etc.)

Therefore, the suffocation is different from the mask from the start line in that it does not cover the nose, but since it is necessary to assume mouth breathing during sleep etc., the air permeability of the mouth covering part 10 is "higher than the mask". First of all, I came up with the idea. Specifically, in view of the test result values of the mask subjected to the air permeability test, the air permeability of the mouth covering portion 10 is higher than 19.8 cubic centimeters / (square centimeter · s) as measured by the JIS L 1096A method. We have created a moisturizer for the oral cavity and mouth area.

After that, from the aspect of effect, the two-layer structure of the mouth covering part 10 is adjusted to complete the trial and error to the best degree among the development / experimental collaborators in the applicant company, and the data numerical value, specifically, In view of the test result values of the oral and oral moisturizers that have been subjected to the breathability test, the breathability of the mouth covering portion 10 is 225.3 cubic centimeters / (square centimeter · s) or more as measured by the JIS L 1096A method. We have created a moisturizer for the oral cavity and mouth area, which is characterized by this. At this point, the mouth cover of the prototype has no layer of filters produced by the Melt Blowing method.

After that, the applicant continued research and development in pursuit of ideal breathability, moisturizing power, and touch. During this time, it was possible to procure a new non-woven fabric material made of polyethylene, which has good breathability, moisturizing power, and feel, and is highly elastic and flexible.
When I immediately made a prototype with this non-woven fabric as the inner layer, the following two problems to be solved arose.
The first issue is suction.

FIG. 5 is a side view of the state immediately after wearing the oral and oral moisturizer.
There is a space in front of the wearer's lips. A space is also formed under the chin, which is a lowering prevention means for preventing the mouth covering portion 10 from being pulled down under the chin and exposing the mouth when the mouth is opened or the like.

FIG. 6 is a diagram schematically showing how suction occurs.
When the prototype with the inner layer as a new material is attached and mouth breathing is repeated for a while, the inner layer 2 of the mouth covering part, which is relatively flexible and stretchable, is pulled by the inspiration, and the mouth circumference provided with great care. It was found that the space of the mouth gradually decreased, the inner layer clung to the mouth, and finally the inner layer was sucked into the mouth.
Therefore, as a means for solving this, it is effective to provide the mouth covering portion with an adhesive portion extending over the inner layer and the outer layer at least in the front portion of the wearer's lips. In the case of the wearer in both figures, if the part drawn as a lips is translated to the left side of the figure, the part to be bonded can be grasped.
The second issue is the occurrence of misalignment and wrinkles in the mouth covering.

FIG. 7 is a diagram schematically showing an example of a process of providing pleats with two blades.
By applying the blade 11 to the fabric from above and below as shown in (b) and forming the shape of (d) through (c), pleats having two creases can be formed.

FIG. 8 is a diagram schematically showing an example of a process of providing pleats by a single blade and a step forming means.
As shown in (b), a step is formed on the fabric by the step forming means 12, and a blade 11 is applied to the step to provide pleats.
These steps are designed according to the number, depth, orientation, etc. of the pleats, and then pressure is applied to secure the creases.

FIG. 9 is a diagram schematically showing how the mouth covering portion is displaced and wrinkled.
It should be noted that FIGS. 7, 8 and 9 are diagrams schematically shown for convenience of explanation. For example, it is convenient to decide which is the outer layer 1 and which is the inner layer 2.
The principle of deviation (upper figure) and wrinkles (lower figure) as shown in Fig. 9 is that when each layer is pushed by the blade, the layer with high elasticity stretches more and is processed by the blade. , It is considered that the phenomenon that it returns after the blade retreats, or conversely, the elastic force is exerted before the blade retreats and a larger material is taken. The difference in flexibility may also have an effect. The higher the flexibility, the higher the degree along the blade, the shorter the distance, and the less excess thickness remains.
The occurrence of such deviations and wrinkles not only reduces the value of the product, but also has concerns about adverse effects on the production line.

As a means for solving this, it is effective to bond the outer layer and the inner layer of the fabric, which is the mouth covering portion, at an appropriate position and size.
So how is it appropriate to glue? First, if bonding is to be performed easily in the production line, it is desirable to perform welding by a pulse method or the like in consideration of other processes and the like. However, the welded part melts and hardens, which hinders ventilation and moisturization, and also causes a feeling of hardness, roughness, resistance, etc. when the skin touches it. That is, if all or most of each layer is fused, the benefits of the inner layer 2, which is the procured material, in terms of breathability, moisturizing power, and touch cannot be obtained.
If the welding is due to a sparse point cloud that does not line up linearly, it is not bad for preventing wrinkles, but the effect on adhesive strength and touch is a concern. Although it feels sensuous to the touch, it is considered best to cling to it slightly when touched, and the spacing between the adhesive parts should not be too large or too small. Adhesive strength and breathability do not change in principle if the total area is about the same as when welding is linear, but if the number of points or the area of one point is increased, ventilation is difficult and the feel is even worse. It will be.

Then, assuming that welding is performed linearly, when examining the direction of the line, the line that does not intersect the crease works on one or two creases nearby, and the influence of other designs is also compared to the case where it intersects the crease. However, it is considered to be relatively inferior in efficiency.
Further, in FIGS. 7 and 8, it is shown that there is a movement that pushes the blade 11 in, but in order to make a movement corresponding to this in the automatic line, the pushing of the blade becomes deeper as it goes ahead. It can be said that it is desirable to assume that the blade tip is designed to have an oblique depth, and that the force is applied in the oblique direction, and the deviation and wrinkles also include the oblique direction.
Furthermore, if the lines are one or more lines but they are parallel lines, it is conceivable that the deviations and wrinkles are piled up in the direction along the lines to become large. By changing the angles of a plurality of lines to form a grid, for example, it can be expected that the accumulation of deviations and wrinkles for each grid will be returned to zero.
Here, a second embodiment corresponding to two new problems will be described as an example.

FIG. 10 is a diagram schematically showing a line to be a fold of pleats and a portion to be pre-adhered in the manufacturing process of the oral and oral moisturizer of the second embodiment.
By making the folds 41, 44, 46 valley folds and the folds 42, 43, 45 mountain folds, pleats having a function of expanding and contracting in the vertical direction can be provided.
Prior to this folding process, a step of welding the double dotted lines as shown by the pre-bonded portion 8 diagonally with respect to the creases in a grid pattern over all layers of the fabric is provided. Each pleated crease has a linear, full-thickness adhesive that intersects the pleated crease. Since it is "each", it does not mean that one welding wire that covers all the creases is indispensable. In addition, the "line" when it is called "linear" does not necessarily require continuity and no break in the length direction and the thickness direction, for example, it is a fusion by two dotted lines. The case of fusion by three broken lines is also included.

As mentioned above, the diagonal grid is diagonal so that the blade goes inside in order to realize "gradual insertion of the blade" so that pleats can be automatically applied in the line. Alternatively, as a result of setting the blade length to gradually increase, the fabric may be displaced in the diagonal direction, which is good for effectively preventing displacement and wrinkles with a smaller welding area. In addition to this reason, it also has a design effect and a blade insertion from the opposite direction, which can be effectively dealt with.
In this second embodiment, the front part of the lips corresponds to the peripheral parts of the first 41 and the second 42 from the top of the crease lines. (In the left-right direction, it is about the width of a general nose from the center of the line to the left and right.) The part slightly above it is the position where the bond is made after folding in half, and the part above it is attached. A cut will be made to expose the area around the person's nose.

FIG. 11 is a perspective view showing an overall image of the appearance of the oral and oral moisturizer of the second embodiment.
For the outer layer 1 of the mouth covering portion 10, polypropylene, which is a material suitable for shape retention and inner fabric protection, is used as an example, and for the inner layer 2, a procured material having a different elasticity is used, taking into consideration the required moisturizing performance and the like. It was used in two layers. It is thought that the importance of measures against slippage and wrinkles will increase as the inner layers are stacked in two layers.
The manufacturing flow is as follows: each layer of dough is unwound from a roll and stacked, and then the welded portion 8 is welded as shown in FIG. 10, pleats 4 are applied, and the pleats 4 are pressed to stabilize the folds of the pleats 4. Similar to the embodiment, the ear hook 3, the semi-cylindrical adhesive portion 5, the lower end adhesive portion 7, the crescent-shaped mark 60, and the like are added.

There is also a process of cutting the mouth covering portion into a size suitable for the mouth covering portion and fixing the upper, lower, left and right ends of the mouth covering portion 10 by welding.
Needless to say, the variation of adhesion is not limited to the example. Adhesion is performed on the outer circumference of the mouth covering part 10 (especially at the left and right ends), but since this is bonding from the top of the overlapping pleats, it is a substitute for this process. It is not preferable to perform a "step of adhering all layers of the laminated material to be formed by including a line intersecting with a line to be a fold of pleats". The same can be said for the process of applying the adhesive portion 5 of the Kamaboko type. It is not preferable to bring the pleating process after this. On the other hand, for example, it is conceivable to add a step of welding and applying the pocket to a position where it does not overlap with the pleats.

Moisturizers around the mouth and mouth are especially effective for protecting the throat, and are also useful for voice actors, lecturers, and voice training personnel. On the other hand, it is stressful not to breathe with your mouth so that you are always conscious and do not open your mouth, and mouth breathing takes in more air, so for example, those who play sports It tends to be mouth breathing. For those who want to stay healthy, they want to keep their moisture by appropriate means, but mouth breathing has many disadvantages, and it is desirable not to acquire that habit.

According to the oral and oral moisturizer of the present invention, there is a sufficient moisturizing effect during mouth breathing such as stuffy nose, mouth breathing habit, unconsciousness due to sleep or concentration, and the coverage range even during nasal breathing. And the back is expected to have a certain moisturizing effect such as not being exposed to dry air.
In any case, even if there is no treatment for nasal breathing, the harmful effects are small compared to the case where there is no treatment for mouth breathing. Although it is conscious, it is not good for habit formation because it causes mouth breathing due to suffocation, especially when sleeping and unconsciously when concentrating. In this regard, further consideration for breathability is more desirable.
Since nasal breathing can be performed unimpeded, comfort can be maintained even when worn, and in addition, sticking out the nose may be an aesthetic advantage, distinguishing from others and vocalizing. It is also considered to be convenient.

According to the present invention, it is possible to provide a convenient oral and oral moisturizer under a wider range of situations.
It can be said that the present invention is also useful for the manufacturer in that it can utilize the mask manufacturing equipment that the manufacturer already has or can introduce relatively easily.
