Description

The present invention relates to a mouth closure.

Nasal breathing is said to have various effects as described below.
1. Improving immunity The nose has "nasal glandular hair", which removes germs and allergens in the air and regulates the temperature and humidity of the inhaled air. It can suppress the uptake of germs and allergens. In addition, since it prevents the intake of cold air, it has the effect of preventing coldness of the body.
2. Improvement of bad breath One of the causes of bad breath is said to be a virus. In the case of mouth breathing, since the mouth is always open, the inside of the mouth becomes dry and becomes an environmental condition that the virus prefers, which causes the virus to multiply. In the case of nasal breathing, it is possible to breathe with the mouth closed, so that saliva can always maintain a certain humidity, so that the propagation of virus can be prevented. In addition, the nasal glands prevent the invasion of viruses that cause bad breath, which leads to improvement of bad breath.
3. Preventing tooth decay and periodontal disease Nasal respiration can prevent evaporation of saliva in the mouth and maintain a certain humidity, and saliva contains a component called "lysozyme" that kills the virus, so saliva in the mouth When kept constant, it has the effect of suppressing the growth of bacteria and viruses and preventing tooth decay and periodontal disease.
4. Effect of Reducing Fatigue It is said that in the case of a person who breathes through the mouth, breathing becomes shallow, oxygen may not be supplied sufficiently to the brain, and it may become oxygen deficient. In the case of deep breathing, sufficient oxygen can be supplied to the brain, resulting in the effect of adjusting the autonomic nerves and relaxing the whole body.
5. When you breathe through your mouth, your tongue often closes your airway when you are asleep, which can cause snoring and sleep apnea. Breathing is a deep breathing that can take in a large amount of oxygen required for sleep, which has the effect of obtaining good quality sleep.
6. Effect of improving posture Nasal breathing is a breathing method of deep breathing by inflating the lungs greatly. Inflating the lungs greatly extends the back muscles. Therefore, breathing through the nose naturally improves the posture.
7. The facial expression changes Nose breathing is performed with the mouth closed, so it has the effect of training the muscles around the mouth and the jaw, and it is said that by changing to nasal breathing, the facial muscles can also be trained. , The face also looks different.
8. Improvement of skin condition Nasal breathing has the effect of preventing dryness in the mouth, and thus also has the effect of preventing evaporation of water in the body. Therefore, it is possible to prevent the skin cells from drying. Further, from the above, the skin immunity is improved and there is an effect of preventing rough skin.
9. Effect of activating metabolism Since nasal breathing allows deep breathing, it can supply a sufficient amount of oxygen to the whole body, has an effect of activating metabolism, and can prepare a lean body.

Conventionally, as a material that suppresses mouth breathing and promotes nasal breathing, a material that covers the central part of the lips that combines the upper and lower lips and that extends at both ends to extend vertically and not easily in the lateral direction was used. It consists of a symmetrically shaped mouse tape body, an adhesive or pressure-sensitive adhesive applied to the back surface of the mouse tape body at the lower end except for the detached portion, and a release paper covering this adhesive or pressure-sensitive adhesive. A characteristic mouse tape has been proposed (for example, Patent Document 1).

JP 2002-336286 A

However, since the above-mentioned mouse tape is coated with an adhesive except for the detached part, the adhesive or the adhesive is also applied to the part which comes into contact with the lips, which causes the lips to become rough and causes inflammation when used for a long period of time. May cause

In addition, in the case of water intake, the mouse tape must be removed and dealt with each time, and then reattached, and it is not uncommon to forget to attach it. Further, when it is difficult to breathe the nose due to stuffy nose or the like, it is necessary to remove it, but it is difficult to pinch and remove the detached portion because the adhesive is applied to the portion other than the detached portion.

The present invention is to solve at least one of the above problems, and an object of the present invention is to provide a mouth closure that is comfortable to use and is easy to handle in an emergency.

In order to solve the above problems, a mouth-closing device according to an aspect of the present invention is a mouth-closing device including a base material layer, an adhesive layer, and a release material layer, and a nose-side pasting portion, By including an elastic material layer between the base material layer and the pressure-sensitive adhesive layer, which includes a chin-side sticking portion and a lip rest portion, and the elastic material layer in the lip rest portion has a restoring force. It is possible to suppress unconscious opening and allow conscious opening.

In addition, the elastic material layer in the lip rest may be provided in a planar shape.

In the present application, the side close to the lips of the mouth closure and its constituent parts is referred to as the "back side" and the opposite side is referred to as the "front side". In addition, in each drawing, for convenience of display, only a part of the layers may be hatched or shaded for display.

<Embodiment 1>
1 to 4 are views showing a mouth closure device 1 according to a first embodiment, FIG. 1(a) is a view showing a front side, FIG. 1(b) is a view showing layers constituting the mouth closure device, and FIG. (C) is a view showing the back side excluding the release material layer, FIG. 2 is a view showing a usage state of the mouthpiece 1, FIG. 3(a), FIG. 3(b), FIG. 3(c), and FIG. It is a figure which shows the other example of the mouth-closure tool 1.

The mouthpiece 1 is configured to include a base material layer 11, an adhesive layer 12, and a release material layer 13.

The base material layer 11 is a layer that constitutes the front side of the mouthpiece 1, and is made of, for example, a non-woven fabric, a synthetic resin film, Japanese paper, or cotton cloth. A material having elasticity may be used for the base material layer 11. As illustrated, in the present embodiment, the base material layer 11 has a single sheet shape.

The adhesive layer 12 is a layer applied (laminated) to the back side of the base material layer 11, and for example, a silicone resin adhesive, an acrylic resin adhesive, a synthetic rubber adhesive, or the like is used. As shown in the figure, the pressure-sensitive adhesive layer 12 in this embodiment is applied in two divided strips on the nose side and the chin side, with the central portion of the base material layer 11 being separated. Further, preferably, as shown in the figure, the adhesive layer on the chin side is applied from a position retracted from the chin side end of the base material layer 11 to the nose side by a predetermined distance. Although not shown, the adhesive layer on the nose side may also be applied from a position retracted from the nose side end of the base material layer 11 to the chin side by a predetermined distance. In the pressure-sensitive adhesive layer, a pressure-sensitive adhesive prepared by kneading a skin moisturizing component such as hyaluronic acid or a protective component may be used. Further, a scent component such as mint may be included.

The release material layer 13 is a layer that constitutes the back side of the mouthpiece 1, and is made of a material such as paper or a synthetic resin film. Although not shown, the release material layer 13 may be coated with a silicone resin or the like so that it can be peeled off from the pressure-sensitive adhesive layer 12 cleanly. Here, although the release material layer 13 is shown in the shape corresponding to the base material layer 11 and in the form of one sheet, it is divided into the shape corresponding to the adhesive layer 12. It may be in the form of two sheets. Further, the release material layer 13 and the backing material layer 15 to be described later are mixed with a fluorescent agent or a light-retaining agent and coated to facilitate the work before sleeping on the bed after the light is turned off.

As shown in FIG. 1, the mouth closing device 1 includes a nose side attaching part 21, a chin side attaching part 22, a lip rest part 30, and an entrance 40. As shown, the mouth closure 1 may include a removal portion 50. As an example, the mouth closing device 1 has a lateral width M of 10 mm to 20 mm and a vertical width L of 45 mm to 65 mm, preferably a lateral width M of 13 mm to 18 mm and a vertical width L of 50 cm to 60 mm.

The nose-side sticking part 21 is a part stuck to the skin on the nose side, and includes a base material layer 11, an adhesive layer 12, and a release material layer 13 in order from the front side. As shown in the figure, the nose-side pasting portion 21 is formed, for example, in such a shape that the end portion has a shape in which two arcs are continuous and the end portion center is notched. As a result, it can be applied without interfering with the nose, and can be applied near the center of the left and right of the mouth using the position of the nose as a guide.

The chin-side attaching portion 22 is a portion to be attached to the chin-side skin, and includes a base material layer 11, an adhesive layer 12, and a release material layer 13 in order from the front side. As an example, the jaw-side pasting portion 22 is formed in a substantially inverted triangular shape with rounded ends. As a result, it is possible to more closely adhere the shape of the jaw.

The vertical width L1 of the nose-side sticking portion 21 and the chin-side sticking portion 22 is, for example, 10 mm to 20 mm, preferably 12 mm to 16 mm. In addition, since the chin side is easy to move (easy to move), the chin side pasting section 22 is provided a little longer than the nose side pasting section 21 so that the chin side does not easily come off and the peel strength is kept balanced. Good.

The lip-contact part 30 is a part that is applied (contacts) to the mouth or the lips and is configured as a part that does not adhere. As an example, the lip rest 30 does not include the pressure-sensitive adhesive layer 12, but includes the base material layer 11 and the release material layer 13 in order from the front side. It should be noted that the lip rest 30 may be configured to include only the base material layer 11 without including the release material layer 13. The lip rest 30 has a vertical width L2 of, for example, 10 mm to 30 mm, preferably 15 mm to 25 mm. It is possible to reduce the width because the lips are attached with the lips closed, but on the other hand, the vertical position at the time of attachment may be slightly moved back and forth.

Since the base material layer 11 is in a state of floating from the lips because the pressure-sensitive adhesive layer 12 is not included here, the lip-contact portion 30 is easily peeled off by applying a fingertip to this portion. For example, if it becomes difficult to breathe your nose during sleep, you can quickly peel it off by grasping this part. Also, since the top and bottom are fixed, pulling the vicinity of the lips sideways with the fingertips makes it easy to get on the fingertips and peel off easily.

The entrance 40 is a portion into which a straw or the like is inserted in order to take in water or the like, and is configured as a through hole. In addition, as described above, it is necessary to peel off during sleep, and when peeling off with a fingertip, the width of the base material layer becomes narrower, so that the fingertip is more likely to be applied. The advancing port 40 shown in the drawing is a vertically long through hole having rounded ends on the nose side and the chin side, but the present invention is not limited to this and may be a perfect circular shape. For example, the entrance 40 has a lateral width M3 of 2 mm to 10 mm, preferably 3 mm to 8 mm. Further, as an example, the vertical width L3 is 10 mm to 30 mm, and preferably 15 mm to 25 mm.

The advancing port 40 is shown as an example including one through hole, but it may be plural. Further, instead of one vertically long through hole, a plurality of substantially circular through holes may be vertically provided.

Here, the detaching portion 50 does not include the pressure-sensitive adhesive layer 12, but includes the base material layer 11 and the release material layer 13 in order from the front side. The detaching portion 50 is a portion to be gripped when only the chin-side attaching portion 22 is detached when the mouth closing tool 1 needs to be opened (released) temporarily when it is attached, or when it is peeled off. In addition, it is also a portion to which a finger is applied when peeling from the release material layer 13 during use, and is for peeling by grasping it with a thumb and an index finger, for example. The detaching section 50 may be configured to include only the base material layer 11 without including the release material layer 13. It should be noted that, although the example in which the detaching portion 50 is provided on the chin side is shown here, it may be provided on the nose side.

The removal portion 50 has, for example, a vertical width L4 of 3 mm to 15 mm, and preferably 5 mm to 10 mm. If it is too long, it will be an obstacle in use, and if it is too short, it will be difficult to pinch it with your fingers. Although not shown, this portion may be large and the inside may be hollowed into a ring shape to form a finger hook portion on which a finger can be hooked.

When the mouth closer 1 is in use, the peeling material layer 13 is peeled off, and then the lip rest is applied to the lips (mouth) as shown in FIG. It is used by attaching the chin-side attachment part to the chin-side skin. At that time, the entrance/exit is located in the central portion of the lip. If you need to drink water, you can deal with it by inserting a straw from the entrance. Further, when it is difficult to breathe the nose due to stuffy nose or the like, it can be dealt with by grasping the detaching portion and removing only the chin-side attaching portion.

Since the mouthpiece 1 does not include an adhesive layer in the lip rest portion, it is gentle on the lips and can avoid the roughening and inflammation of the lips due to the use of the mouthpiece. Further, in the case of water intake or the like, it is sufficient to insert a straw from the entrance and exit, and therefore, it is possible to reduce the frequency of removal and reduce forgetting to stick.

As shown in FIG. 3(a), the mouth closure 1 has a vertically long rectangular shape with rounded corners, a vertically long elliptical shape as shown in FIG. 3(b), and a vertically long elliptical shape as shown in FIG. 3(c). Alternatively, the end of the jaw-side pasting portion may be formed in a shape that extends in an arc shape.

Moreover, the mouth-closure device 1 may be made of a light-transmissive material for the base material layer so as to be inconspicuous when attached and used. Moreover, the mouth-closure tool 1 does not have its own release layer, and a plurality of mouth-closure tools 1 may be arranged in one release layer to share one release layer.

4A and 4B are views showing another example of the mouth closing device 1, FIG. 4A is a view showing each layer of the mouth closing device 1, and FIG. 4B is a view seen from the front side (here, For convenience of explanation, the base material layer is made of a transparent material). Here, the mouth-closure device 1 is configured to include a backing layer 15, as shown in FIG.

As illustrated, the pressure-sensitive adhesive layer 12 is applied so as to cover the entire back side of the base material layer 11, and the backing agent layer 15 is arranged so as to cover the central portion of the pressure-sensitive adhesive layer 12. In other words, the backing layer 15 arranges the pressure-sensitive adhesive layer 12 so as to be exposed in two divided strips on the nose side and the chin side. In this case, the lip rest portion 30 is configured to include the base material layer 11, the adhesive layer 12, the backing layer 15, and the release material layer 13 in this order from the front side. In other words, the backing layer 15 can be disposed only on the back side of the adhesive layer 12 in the lip rest 30. As a result, the lip rest portion 30 is configured as a non-adhesive portion.

For the backing layer 15, for example, a material such as a non-woven fabric, a synthetic resin film, Japanese paper, or cotton cloth is used. The backing layer 15 may be made of an inconspicuous translucent material, or a pink or red material such as a lip color.

Further, preferably, as shown in the drawing, the backing layer 15 may be arranged also on the jaw side end portion. In other words, the adhesive layer 12 on the chin side may be arranged so as to be exposed from a position retracted from the chin side end portion to the nose side by a predetermined distance. In this case, the detaching section 50 is configured to include the base material layer 11, the adhesive layer 12, the backing layer 15, and the release material layer 13 in this order from the front side. In other words, the backing layer 15 can also be arranged on the back side of the adhesive layer 12 in the detaching section 50. As a result, the detaching portion 50 is configured as a non-adhesive portion. In addition, you may dare to use the material of the color which stands out for the removal part 50.

Further, the mouth closer 1 may include a test patch 60 for an allergy test, and the test patch 60 may be provided independently of the main body of the mouth closer 1 as illustrated. The test patch 60 can have a size of, for example, about 8 mm to 12 mm, and preferably has a circular shape with a diameter of about 10 mm.

<Embodiment 2>
5 and 6 are views showing the mouth closing device 1a according to the second embodiment, FIG. 5(a) is a perspective view of the mouth closing device 1a, and FIG. 5(b) is a view showing each layer of the mouth closing device 1a. FIG. 6 is a view showing a usage state of the mouth closing device 1a.

The mouth closure 1a includes a base material layer 11, an elastic material layer 14a, a backing material layer 15a, an adhesive layer 12, and a release material layer 13.

The base material layer 11 is a layer that constitutes the front side of the mouth closure device 1a, and is made of, for example, a nonwoven fabric, a synthetic resin film, Japanese paper, cotton cloth, or other material. A material having elasticity may be used for the base material layer 11. As illustrated, in the present embodiment, the base material layer 11 has a single sheet shape.

The elastic material layer 14a is a layer arranged in contact with the back side of the base material layer 11 and is made of, for example, a thin plate-shaped metal member or a thin plate-shaped resin member. The elastic material layer 14 a recedes inward from the edge of the base material layer 11 and is arranged in a narrower area than the base material layer 11. As an example, as shown in the figure, the elastic material layer 14a is distributed in a long and narrow range in the central portion of the base material layer 11. The elastic material layer 14a may be attached and fixed to the base material layer 11 with an adhesive, a pressure-sensitive adhesive or the like (not shown), or may be fixed by being sandwiched between the base material layer 11 and a backing material layer 15a described later. May be done.

The backing layer 15a is a layer that is arranged in contact with the back side of the region in which the elastic layer 14a is present and the back side of the base material layer 11 in the region where the elastic layer 14a is not present. Materials such as synthetic resin film, Japanese paper, and cotton cloth are used. The backing material layer 15a is arranged so as to cover the elastic material layer 14a. The illustrated backing material layer 15a has a shape corresponding to the base material layer 11 and is arranged so as to cover the entire base material layer 11 with the elastic material layer 14a interposed therebetween, but the present invention is not limited to this. The elastic material layer 14a may be arranged in such a size as to cover the elastic material layer 14a. Further, it may cover only both ends of the elastic material layer 14a. A material having elasticity may be used for the base material layer 11. The backing layer 15a may be attached to the elastic material layer 14a with an adhesive or the like not shown. Further, in the region where the elastic material layer 14a does not exist, the backing layer 15a may be integrated by being at least partially bonded to the base material layer 11 by thermocompression bonding or the like.

The pressure-sensitive adhesive layer 12 is a layer that is applied (laminated) to the backing layer 15a in the region where the backing layer 15a is present, and is applied (laminated) to the back side of the base material layer 11 in the region where the backing layer 15a is not present. A resin adhesive, an acrylic resin adhesive, a synthetic rubber adhesive, or the like is used. As shown in the figure, the pressure-sensitive adhesive layer 12 in the present embodiment is applied in two divided strips on the nose side and the chin side with a central portion therebetween.

The release material layer 13 is a layer that covers the pressure-sensitive adhesive layer 12 from the back side, and a material such as paper or a synthetic resin film is used. Although not shown, a silicone resin or the like is applied to the release material layer 13 so that the release material layer 13 can be peeled off cleanly from the adhesive layer 12. Although the illustrated release material layer 13 is in the form of one sheet, it may be formed in two divided strips so as to cover only the adhesive layer 12. Further, it may be provided along the backing layer 15a.

As illustrated, the mouth closure device 1a includes a nose-side sticking portion 21a, a chin-side sticking portion 22a, and a lip rest portion 30a.

The nose-side attaching portion 21a is a portion to be attached to the skin on the nose side, and includes a base material layer 11, an elastic material layer 14a, a backing material layer 15a, an adhesive layer 12, and a release material layer 13 in order from the front side. It As shown in the figure, the nose-side pasting portion 21a is formed, for example, in such a shape that the end portion has a shape in which two arcs are continuous and the end portion center is notched. As a result, it can be attached without interfering with the nose.

In the nose-side pasting portion 21a, the elastic material layer 14a has a narrower distribution area than the base material layer 11, and as an example, the elastic material layer 14a extends from the edge portion to the inner side (the lip contact portion 30a side). It is placed backwards.

The chin-side attaching portion 22a is a portion attached to the chin-side skin, and includes a base material layer 11, an elastic material layer 14a, a backing material layer 15a, an adhesive layer 12, and a release material layer 13 in this order from the front side. It As an example, the jaw-side attaching portion 22a is formed in a substantially inverted triangular shape with rounded ends. As a result, it is possible to more closely adhere the shape of the jaw.

In the chin-side pasting portion 22a, the elastic material layer 14a has a narrower distribution area than the base material layer 11, and as an example, the elastic material layer 14a extends from the edge portion to the inner side (the lip contact portion 30a side). It is placed backwards.

The lip-contacting portion 30a is a portion that is applied (contacts) to the lips (mouth), does not include the adhesive layer 12, and includes the base material layer 11, the elastic material layer 14a, the backing material layer 15a, and the release material layer 13 in order from the front side. It is configured to include. It should be noted that the lip rest 30a may not include the release material layer 13.

The elastic material layer 14a in the lip rest 30a has a protruding shape protruding toward the base material layer 11 side. As an example, as shown in the figure, the elastic material layer 14a in the lip rest 30a has a substantially inverted V shape protruding toward the base material layer 11 side. In other words, the elastic material layer 14a has a shape in which two sides of 31a and 32a are continuous at a predetermined angle. In the lip rest 30a, the elastic material layer 14a also pushes up the base material layer 11a to form a similar shape, and when the backing material layer 15a is attached to the elastic material layer 14a, the backing material layer 15a also has the same shape. When the backing material layer 15a is not attached to the elastic material layer 14a, the backing material layer 15a in the lip rest 30a is in a loosened state accordingly.

Note that the nose-side sticking portion 21a and the chin-side sticking portion 22a do not necessarily have to be flat. The shape may be such that a part or the whole is curved in accordance with the applied part. Further, the base material layer 11 and the backing material layer 15a may not cover the entire elastic material layer 14a, but may only cover the vicinity of the nose-side attaching portion 21a and the chin-side attaching portion 22a.

When the mouth closer 1a is used, the release material layer 13 is peeled off, and as shown in FIG. 6, the nose side pasting part is pasted on the nose side skin so that the lip rest part is put on the lip. , The chin-side attachment part is attached to the chin-side skin. If an attempt is made to open (open the mouth) in this state, a force that resists the restoring force must be applied to both sides of the elastic material layer 14a that are substantially inverted V-shaped. However, since the force of the unconscious movement of the opening during sleep is weak, it is difficult to deform both sides of the substantially inverted V shape in the separating direction, and it is difficult to reach the opening. This suppresses the unconscious opening. On the other hand, when consciously attempting to open, the movement of the opening has a large force, and a force that opposes the restoring force is applied to both sides of the substantially inverted V-shape to deform it in the separating direction and the opening can be performed. Like Then, when the conscious movement of the opening is stopped, both sides of the substantially V-shaped elastic material layer 14a return to the original state due to the restoring force and return to the unconscious movement restrained state.

Since mouth breathing during sleep is often performed by an unconscious opening, the mouth closing device 1a can effectively suppress the mouth breathing by suppressing the unconscious opening, and snoring or the like due to this. It is possible to reduce the adverse effects of. In addition, since a conscious opening is also possible, it is possible to flexibly cope with cases such as when water intake and auxiliary mouth breathing are necessary.

In addition, for example, when the nose becomes clogged during sleep and the suffering increases, it is possible to increase the safety by allowing the patient to open without force even if he/she is unconscious. The elastic strength of the elastic material layer 14a can be set according to age physical strength and the like. For example, the force required to release the elastic material layer 14a in the lip rest 30a by 5 mm (expand in the separating direction) is 10 g to 200 g, preferably 20 to 80 g.

In addition, since the mouth-closer 1a does not include an adhesive layer in the lip rest portion, it is gentle on the lips, and it is possible to avoid the roughness and inflammation of the lip due to the use of the mouth-closer. In addition, since it is not necessary to remove it during use, it is possible to prevent forgetting to attach it.

As a manufacturing method, the base material layer 11, the backing material layer 15a, the release material layer 13 and the like are attached to the elastic material layer 14a which is previously curved and molded, and the base material layer 11 is applied to the flat elastic material layer 14a. A method of bending the elastic material layer 14a after attaching the backing material layer 15a, the release material layer 13 and the like is conceivable. The punching of the shape or the like is appropriately combined with each step.

<Modification 1 of Embodiment 2>
FIG. 7: is a figure which shows the mouth-closure tool 1b which concerns on the modification 1 of Embodiment 2. As shown in FIG. The same components as those in the above embodiment are designated by the same reference numerals, and the description thereof will be omitted. The mouth closer 1b is different from the mouth closer 1a according to the second embodiment in that the mouth closer 1b includes the shape of the lip rest portion 30b and the outlet 40b.

The lip-contact part 30b is a part that is applied (contacts) to the lips (mouth) and does not include the adhesive layer 12, and the base material layer 11, the elastic material layer 14a, the backing material layer 15a, and the release material layer 13 are sequentially arranged from the front side. It is configured to include. In addition, the lip-contact part 30b does not need to include the release material layer 13. The lip rest portion 30b is provided in a protruding shape protruding toward the base material layer side, and the elastic material layer 14a is provided in an arc shape here.

The advancing port 40b is formed as a through hole at a substantially central portion of the mouth closing device 1b. Preferably, the entrance 40b is formed so as to penetrate at least a part of the elastic material layer 14a in the lip rest 30b. For example, as shown in the figure, the advancing port 40b is a vertically long through hole that penetrates the central portion of the elastic material layer 14a in the lip rest portion 30b, and divides the elastic material layer 14a in the lip rest portion 30b into two strip-shaped portions. Is formed as.

Since the mouth closing device 1b includes the entrance/exit 40b in the mouth closing portion 30b, the portion that contacts the lips is reduced, and the mouth closing tool 1b can be used more comfortably. Further, by providing the advancing port 40b, the strength of the biasing force of the elastic material layer 14a can be adjusted.

The mouthpiece 1d includes a base material layer 11d, an elastic material layer 14d, a pressure-sensitive adhesive layer 12, and a release material layer 13.

The base material layer 11d is a layer constituting the front side of the mouthpiece 1d, and is made of, for example, a non-woven fabric, a synthetic resin film, Japanese paper, or cotton cloth. A material having elasticity may be used for the base material layer 11d. As illustrated, in the present embodiment, the base material layer 11d is in the form of two sheets divided into a nose side and a chin side.

The pressure-sensitive adhesive layer 12 is a layer applied (laminated) to the back side of the base material layer 11d, and for example, a silicone resin pressure-sensitive adhesive, an acrylic resin pressure-sensitive adhesive, a synthetic rubber pressure-sensitive adhesive, or the like is used.

The elastic material layer 14d is a layer that partially constitutes the front side of the mouth closure device 1d and that is partially disposed on the back side of the adhesive layer 11d. For example, a thin plate-shaped metal member, a thin plate-shaped resin member, or the like is used. Used. The elastic material layer 14d recedes inward from the edge of the base material layer 11a, and is arranged in the central portion of the mouth closure device 1d. The elastic material layer 14d may be attached and fixed to the base material layer 11 with an adhesive, a pressure sensitive adhesive, or the like (not shown), or as shown in FIG. It may be affixed to and fixed to.

The release material layer 13 is a layer that covers the pressure-sensitive adhesive layer 12 from the back side, and a material such as paper or a synthetic resin film is used. Although not shown, a silicone resin or the like is applied to the release material layer 13 so that the release material layer 13 can be peeled off cleanly from the adhesive layer 12. As illustrated, in the present embodiment, the release material layer 13 is in the form of two sheets. Further, the release material layer 13 may cover the portion where the elastic material layer 14d exists as shown in the figure, or may cover only the layer where the elastic material layer 14d does not exist and the adhesive layer 12 is exposed on the back side. May be.

As shown in the figure, the mouth closing device 1d includes a nose-side attaching portion 21d, a chin-side attaching portion 22d, and a lip rest portion 30d.

The nose-side attaching portion 21d is a portion to be attached to the skin on the nose side, and includes a base material layer 11d, an elastic material layer 14d, an adhesive layer 12, and a release material layer 13 in order from the front side. As an example, the nose-side pasting portion 21d is formed in an elliptical shape as shown in the drawing.

In the chin-side pasting portion 22a, the arrangement region of the elastic material layer 14d is narrower than that of the base material layer 11d. As an example, as shown in the figure, the elastic material layer 14d extends from the edge portion to the inside (the lip contact portion 30d side). It is set back.

The lip-contacting portion 30d is a portion applied (contacted) to the lips (mouth) and is configured to include only the elastic material layer 14d without including the adhesive layer 12.

By including the elastic material layer 14d, the lip rest 30d is biased in the closing direction. As an example, the elastic material layer 14d in the lip rest portion 30d has a U shape or a shape in which the U shape is repeatedly inverted and bent. For example, as shown in the drawing, the elastic material layer 14d in the lip rest portion 30d has a self-shaped shape in which two U-shaped shapes are inverted and bent. The elastic material layer 14d is urged in such a manner that opposite sides of the U-shape are close to each other.

When the mouth closer 1d is in use, the release material layer 13 is peeled off, and the nose side attachment part is attached to the skin on the nose side so that the lip rest part is applied to the lips, and the jaw side attachment part is placed on the chin. Attached to the side skin. If an opening is to be made in this state, a force that resists the restoring force must be applied to each of the U-shaped sides of the elastic material layer 14d. However, since the force of the unconscious movement of the opening during sleep is weak, it is difficult to deform each side in the separating direction, and it is difficult to reach the opening. This suppresses the unconscious opening. On the other hand, when consciously attempting to open, the force of the opening is large, and each side of the U-shape is deformed in the separating direction by applying a force against the restoring force so that the opening can be performed. Become. Then, when the conscious movement of the opening is stopped, the U-shaped sides of the elastic material layer 14d return to their original state due to the restoring force, and return to the unconscious movement restrained state.

Since mouth breathing during sleep is often performed by the unconscious opening, the mouth closure device 1d can effectively suppress the mouth breathing by suppressing the unconscious opening, and snoring and the like due to this. It is possible to reduce the adverse effects of. In addition, since a conscious opening is also possible, it is possible to flexibly cope with cases such as when water intake and auxiliary mouth breathing are necessary.

In addition, since the lip-contacting portion of the mouth-closing device 1d does not include an adhesive layer, it is gentle on the lips, and it is possible to avoid the roughness and inflammation of the lips due to the use of the mouth-closing device. In addition, since it is not necessary to remove it during use, it is possible to prevent forgetting to attach it.

Further, the mouth-closure tool 1d can reduce the manufacturing cost by simplifying the configuration.

<Embodiment 4>
10: is a figure which shows the mouth-closure tool 1e which concerns on Embodiment 4. As shown in FIG. The mouth closer 1e is different from the mouth closer 1d according to the third embodiment only in the elastic material layer 14e and the lip rest 30e.

The elastic material layer 14e is a layer that partially constitutes the front side of the mouthpiece 1e and is partially disposed on the back side of the base material layer 11d , and for example, a material having a strong elastic force such as rubber is used. The elastic material layer 14e recedes inward from the edge portion of the base material layer 11d, and is distributed in an elongated range in the central portion of the mouthpiece 1e. The elastic material layer 14e, may be fixed attached to the base layer 11 d with an adhesive or a pressure-sensitive adhesive or the like, not shown, be fixed attached to the base layer 11d by the adhesive layer 12 Good.

Attached to the side skin. If an opening is to be made in this state, a force that opposes the restoring force of the elastic material layer 14e must be applied to extend the elastic material layer 14e. However, since the unconscious movement of the opening during sleep is weak in force, it is difficult to extend the opening, and it is difficult to reach the opening. This suppresses the unconscious opening. On the other hand, in the case of intentionally opening, the movement of the opening has a large force, and a force against the restoring force is applied to the elastic material 14e to extend the elastic material 14e so that the elastic material 14e can be opened. Then, when the conscious movement of the opening is stopped, the elastic material layer 14e returns to the original state due to the restoring force, and returns to the unconscious movement restrained state.

Since mouth breathing during sleep is often performed by the unconscious opening, the mouth closure device 1e can effectively suppress the mouth breathing by suppressing the unconscious opening, and snoring and the like due to this. It is possible to reduce the adverse effects of. In addition, since a conscious opening is also possible, it is possible to flexibly cope with cases such as when water intake and auxiliary mouth breathing are necessary.

In addition, since the mouth-closer 1e does not include an adhesive layer in the lip rest portion, it is gentle on the lips, and it is possible to avoid the roughness and inflammation of the lip due to the use of the mouth-closer. In addition, since it is not necessary to remove it during use, it is possible to prevent forgetting to attach it.

Furthermore, the mouth-closure tool 1e can also reduce manufacturing cost by simplifying a structure.

<Fifth Embodiment>
