The mouth breathing suppression tape of the present invention is used, for example, by being attached to the mouth at bedtime, and by keeping the mouth closed so as not to open, the mouth breathing during sleep is suppressed and the nose is suppressed. It promotes breathing. In the present disclosure, in the mouth breathing suppression tape, the direction in which the mouth is longitudinally traversed (from the upper lip to the lower lip) when attached to the mouth is defined as the "vertical direction", and the direction orthogonal to the vertical direction is defined as the "horizontal direction". , The vertical size is the "length" and the horizontal size is the "width".

Hereinafter, embodiments of the mouth breathing inhibitory tape of the present invention will be described with reference to the accompanying drawings. As shown in FIG. 1, the mouth breathing suppression tape 1 of the present embodiment is composed of a base material 2 and an adhesive layer 3 provided on the back surface of the base material 2 by applying an adhesive, and mouth breathing suppression. The entire back surface of the tape 1 is made an adhesive surface by the adhesive layer 3. The mouth breathing suppression tape 1 is attached to the mouth so as to straddle the upper lip and the lower lip by adhering at least one end in the vertical direction (longitudinal direction) to the upper lip and the other end to the lower lip. In the present disclosure, the "back surface" is the surface on the side to be attached to the mouth. When the mouth breathing suppression tape 1 is not in use, a release film is attached to the back surface thereof.

The base material 2 is formed of a sheet material having breathability and flexibility, such as a non-woven fabric, a woven cloth, a paper such as Japanese paper, and a resin sheet having a large number of pores. The above-mentioned sheet material may be used alone to form the base material 2, or two or more types may be combined to form the base material 2.

The base material 2 has a vertically long shape in which the length, which is the size in the vertical direction, is longer than the width, which is the size in the horizontal direction in a plan view. The vertically long shape is not particularly limited, and can be various shapes such as a rectangular shape, a rounded rectangular shape, an elliptical shape, a bullet shape, and a gourd shape in a plan view. In the present embodiment, the base material 2 has a wavy shape in which the entire left and right side edges 20 and 21 along the vertical direction (length direction) undulate inward and outward. The base material 2 may or may not be line-symmetrical with respect to the center line which is parallel in the vertical direction and passes through the center of the width. Further, the base material 2 may or may not be line-symmetrical with respect to the center line which is parallel in the lateral direction and passes through the center of the length.

The length of the base material 2 is not particularly limited as long as it extends from the upper lip to the lower lip when the mouth breathing inhibitory tape 1 is attached to the mouth, but is preferably 30 mm or more and 60 mm or less, and more preferably 35 mm or more. It is 45 mm or less. The width of the base material 2 is not particularly limited as long as it can secure a sufficient contact area with the mouth when the mouth breathing inhibitory tape 1 is attached to the mouth and cannot be easily peeled off from the mouth, but is preferably 15 mm or more. It is 40 mm or less, more preferably 20 mm or more and 30 mm or less. The thickness of the base material 2 is not particularly limited as long as it can sufficiently secure the strength of the mouth breathing inhibitory tape 1, but is preferably 0.1 mm or more and 0.8 mm or less, and more preferably 0.2 mm or more and 0. It is 4 mm or less.

As the pressure-sensitive adhesive forming the pressure-sensitive adhesive layer 3, for example, a pressure-sensitive adhesive called a silicon-based pressure-sensitive adhesive, a urethane-based pressure-sensitive adhesive, an acrylic-based pressure-sensitive adhesive, or a rubber-based pressure-sensitive adhesive can be used. It is preferable to use an acrylic pressure-sensitive adhesive from the viewpoint that many materials have a proven track record as the intended tape material, and a relatively inexpensive and highly safe material can be selected from a wider range of options. The acrylic pressure-sensitive adhesive is made of an acrylic polymer, and the strength of the adhesive strength can be controlled by controlling the type of monomer, the molecular weight of the polymer, the cross-linking density, and the like.

The mouth breathing suppression tape 1 of the present embodiment is predetermined so as not to be easily peeled off from the mouth due to unconscious movements of the user during sleep, for example, mouth movements such as breathing, coughing, creaking, and sleeping. It has peeling resistance and extensibility. Hereinafter, a specific description will be given.

(1) Maximum peeling force by 0 degree peeling test in the vertical direction (length direction) The maximum peeling force by the 0 degree peeling test in the vertical direction (length direction) is the movement to open the mouth up and down during sleep. It is a numerical value indicating resistance (difficulty in peeling) that the mouth breathing suppression tape 1 is peeled from the mouth due to (movement of the upper lip and the lower lip apart). When the mouth opens up and down, the mouth breathing suppression tape 1 attached to the mouth is pulled in the opposite direction at one end and the other end in the vertical direction (length direction), but the mouth breathing suppression tape 1 is pulled in the vertical direction. The greater the maximum force that can be withstood until it peels off from the mouth when pulled by, the harder it is to peel off from the mouth. Therefore, the mouth breathing inhibitory tape 1 needs to have a maximum peeling force of a predetermined value or more in the 0 degree peeling test in the vertical direction (length direction).

The 0 degree peeling test in the vertical direction (length direction) is performed by the following method. First, as shown in FIG. 2A, 50% of the area S of the mouth breathing inhibitor tape 1 protrudes from the test plate 10 in the vertical direction (length direction) on the flat surface of the polypropylene test plate 10. It is attached to the surface via the adhesive layer on the back surface. For example, when the mouth breathing suppression tape 1 is parallel to the lateral direction (width direction) and is axisymmetric with respect to the center line passing through the center of the length, the mouth breathing suppression is performed with the center line passing through the center of the length as a boundary. The tape 1 is pushed out from the test plate 10. Next, as shown in FIG. 2 (B), one reciprocating roll is performed on the entire area of the portion of the mouth breathing suppression tape 1 attached to the test plate 10 with the roller 11 weighing 2 kg in contact with the roller 11. Then, apply a load and firmly attach the mouth breathing suppression tape 1 to the test plate 10. Next, as shown in FIG. 2C, in the mouth breathing suppression tape 1, the entire end portion on the side protruding from the test plate 10 in the vertical direction (length direction) is grasped by the chuck 12, and the chuck 12 is held by the test plate. A tensile tester (Shimadzu Seisakusho Co., Ltd.) not shown in the direction parallel to the surface of 10 and protruding from the test plate 10 of the mouth breathing suppression tape 1 (0 ° direction of the arrow (length direction of the mouth breathing suppression tape 1)). It is pulled at a speed of 300 mm / min using the AUTOGRAPH AGS-500NX) manufactured by Japan. The maximum peeling force is obtained by measuring the force when the mouth breathing inhibitory tape 1 is pulled from the test plate 10 until it is peeled off, and measuring the maximum value thereof.

Since the maximum peeling force in the 0-degree peeling test in the vertical direction (length direction) is 7 N or more, the mouth breathing suppression tape 1 has high durability against the movement of the mouth to open up and down during sleep. Adhesion to the upper and lower lips of both ends of the mouth breathing suppression tape 1 in the vertical direction (longitudinal direction) can be maintained, and the mouth breathing suppression tape 1 can be prevented from peeling off from the mouth. This maximum peeling force is not particularly limited as long as it is 7 N or more, but it is preferably 30 N or more from the viewpoint of effectively making it difficult for the mouth breathing inhibitor 1 to be peeled from the mouth, while the upper limit thereof is pain when peeling. It is preferably 40 N or less from the viewpoint of making it difficult to feel.

For the maximum peeling force by the 0 degree peeling test in the vertical direction (length direction), in addition to the adhesive force by the adhesive layer 3 (adhesive), the material and dimensions (length, width and thickness) of the base material 2 are appropriately adjusted. By doing so, the size can be controlled to a desired size.

(2) Elongation rate in the vertical direction (length direction) The elongation rate in the vertical direction (length direction) refers to the fact that the mouth breathing inhibitor tape 1 is peeled off from the mouth due to the movement of the mouth to expand up and down during sleep. It is a numerical value indicating resistance (difficulty of peeling). When the mouth expands up and down, the mouth breathing suppression tape 1 attached to the mouth is pulled in the opposite direction at one end and the other end in the vertical direction (length direction). At this time, the mouth breathing suppression tape 1 is pulled. By expanding and contracting in the vertical direction (length direction), it becomes possible to follow the movement of the mouth and it becomes difficult to peel off from the mouth. On the other hand, if the mouth breathing suppression tape 1 is stretched too much in the vertical direction (longitudinal direction), the mouth may open even when the mouth breathing suppression tape 1 is attached to the mouth, and mouth breathing may not be suppressed. Therefore, the mouth breathing suppression tape 1 needs to be appropriately stretched in the vertical direction (length direction).

The elongation rate in the vertical direction (length direction) is measured by the following method. First, as shown in FIG. 3A, both ends of the mouth breathing suppression tape 1 in the vertical direction (length direction) are grasped by a pair of chucks 12A and 12B with a gap of 10 mm from each other. That is, the mouth breathing suppression tape 1 is attached to the pair of chucks 12A, with the center line parallel to the lateral direction (width direction) of the mouth breathing suppression tape 1 as a boundary and passing through the center of the length, leaving a portion within a range of 5 mm above and below. Grab with 12B. Next, as shown in FIG. 3B, one chuck 12A is placed in the direction opposite to the other chuck 12B at 100 mm / min using a tensile tester (AUTOGRAPH AGS-500NX manufactured by Shimadzu Corporation) (not shown). It is pulled at a speed, and as shown in FIG. 3C, the distance Lmm between the chucks 12A and 12B at the time when a load of 500 gf is applied to the mouth breathing suppression tape 1 is measured. The ratio ((L-10) / 10) of the mouth breathing suppression tape 1 to the distance Lmm between the chucks 12A and 12B after stretching with respect to the distance 10 mm between the chucks 12A and 12B before stretching is calculated as a percentage, and this is calculated as a percentage. Let it be a rate.

Since the elongation rate in the vertical direction (length direction) is 5% or more, the mouth breathing suppression tape 1 has high followability to the movement of the mouth to open up and down during sleep, and the mouth moves up and down. Accordingly, the mouth breathing suppression tape 1 can be extended in the vertical direction (longitudinal direction) to maintain adhesion to the mouth, so that the mouth breathing suppression tape 1 can be prevented from peeling off from the mouth. On the other hand, since the elongation rate in the vertical direction (length direction) is 25% or less, the mouth breathing suppression tape 1 does not excessively extend in the vertical direction (length direction) following the vertical movement of the mouth. Mouth breathing can be suppressed because it suppresses the opening of the mouth. The elongation rate in the vertical direction (length direction) is not particularly limited as long as it is 5% or more and 25% or less.

The stretchability of the mouth breathing suppression tape 1 in the lateral direction (width direction) is not particularly limited, and the length of extension when the same load is applied and pulled is about the same as in the vertical direction (length direction). Alternatively, it may be larger than the vertical direction (length direction).

As described above, the mouth breathing inhibitory tape 1 of the present embodiment has a maximum peeling force of 7 N or more in the 0 degree peeling test in the vertical direction (longitudinal direction) and an elongation rate in the vertical direction (longitudinal direction). Since it is 5% or more and 25% or less, even if the user's mouth moves during sleep, it does not peel off from the mouth and does not stretch excessively, so that the state of being well attached to the mouth is maintained and mouth breathing is suppressed. be able to.

Further, the mouth breathing suppression tape 1 of the present embodiment prevents the user from easily peeling off from the mouth by contact with bedding (for example, a pillow, a futon, a mattress, etc.) due to the sleeping phase, which is an unconscious movement of the user during sleep. Therefore, it has a predetermined peeling resistance. Hereinafter, a specific description will be given.

(3) Average peeling force by 180 degree peeling test in the vertical direction (length direction) The average peeling force by 180 degree peeling test in the vertical direction (length direction) is the contact of the mouth breathing suppression tape 1 with the bedding during sleep. It is a numerical value indicating the resistance (difficulty of peeling) to the fact that a part of it is rolled up and then the whole is gradually peeled from the mouth. When the mouth breathing suppression tape 1 is rubbed against the bedding, the end portion in the vertical direction (length direction) is mainly rolled up from the mouth, and after that, the entire portion is rolled up from the end portion rolled up due to the rubbing with the bedding. It gradually tries to peel off from the mouth, but the greater the overall force that resists the peeling from the mouth of the mouth breathing suppression tape 1 when the end in the vertical direction (length direction) is rolled up, the more difficult it is to peel off from the mouth. .. Therefore, it is preferable that the mouth breathing inhibitory tape 1 has an average peeling force of a predetermined value or more in a 180-degree peeling test in the vertical direction (length direction).

The 180 degree peeling test in the vertical direction (length direction) is performed by the following method. First, as shown in FIG. 4A, the entire mouth breathing inhibitory tape 1 is attached to the flat surface of the polypropylene test plate 10 via the adhesive layer on the back surface. Next, as shown in FIG. 4 (B), the mouth breathing suppression tape 1 is rolled over the entire mouth breathing suppression tape 1 in a state where the roller 11 having a weight of 2 kg is in contact with the mouth breathing suppression tape 1 to apply a load. 1 is firmly attached to the test plate 10. Next, as shown in FIG. 4C, one end of the mouth breathing suppression tape 1 in the vertical direction (length direction) is rolled up from the test plate 10 and grasped by the chuck 12, and the chuck 12 is grasped by the chuck 12 on the surface of the test plate 10. A tensile tester (not shown) parallel to and in the direction of the other end of the mouth breathing suppression tape 1 in the vertical direction (length direction) (180 ° direction of the arrow (length direction of the mouth breathing suppression tape 1)). Pull at a speed of 300 mm / min using AUTOGRAPH AGS-500NX) manufactured by Shimadzu Corporation. The average peeling force is obtained by measuring the force when the mouth breathing inhibitory tape 1 is pulled from the test plate 10 until it is peeled off, and treating the measured value with a convex point average.

The average peeling force in the 180-degree peeling test in the vertical direction (length direction) is preferably 1N or more, and as a result, the mouth breathing inhibitory tape 1 adheres well to the mouth and is therefore durable against rubbing against bedding. It has high sex and can make it difficult for the mouth breathing suppressing tape 1 to come off from the mouth. The average peeling force in the 180-degree peeling test in the vertical direction (length direction) is more preferably 3N or more from the viewpoint of effectively preventing the mouth breathing inhibitor tape 1 from peeling from the mouth, while the upper limit is peeled off. It is preferably 5N or less from the viewpoint of making it difficult to feel the pain at the time.

The average peeling force in the 180-degree peeling test in the vertical direction (length direction) can be controlled to a desired size by appropriately adjusting the adhesive force of the adhesive layer 3 (adhesive) and the like.

Further, the mouth breathing inhibitory tape 1 of the present embodiment has predetermined peeling characteristics in order to suppress physical irritation given to the skin when peeled from the mouth after use so as not to cause pain. .. Hereinafter, a specific description will be given.

(4) Peeling energy by 0 degree peeling test in the vertical direction (length direction) When the mouth breathing suppression tape 1 is peeled off from the state of being attached to the mouth, the adhesive layer 3 (adhesive) has a hard tactile sensation. While it peels off and gives a strong stimulus to the skin momentarily, the adhesive layer 3 (adhesive) has a soft touch and peels off firmly to give a weak stimulus to the skin, so that it does not give a strong stimulus. Therefore, the one having a soft touch to the adhesive layer 3 (adhesive) does not damage the skin when the mouth breathing inhibitory tape 1 is peeled off from the mouth.

As a result of diligent research by the present inventor, the tactile sensation of the adhesive layer 3 (adhesive) correlates with the peeling energy required in the 0 degree peeling test in the vertical direction (length direction) of the mouth breathing inhibitory tape 1 of the above (1). I found out to do. Specifically, when the adhesive layer 3 (adhesive) has a hard tactile sensation, it acts from the time when the mouth breathing inhibitory tape 1 is pulled until it is peeled off from the test plate 10, for example, as shown in FIG. 5 (A). The behavior of the tensile force (vertical axis is tensile force (N), horizontal axis is stroke (mm)) draws a curve that reaches the peak instantly with a sharp curve, but the adhesive layer 3 (adhesive) has a soft touch. In the case, for example, as shown in FIG. 5 (B), the behavior draws a curve that slowly reaches the peak with a gentle curve. Therefore, the peeling energy represented by the behavior and the area surrounded by the horizontal axis is larger when the pressure-sensitive adhesive layer 3 (adhesive) is soft than when it is hard to the touch. Therefore, it is preferable that the mouth breathing suppression tape 1 has a peeling energy of a predetermined value or more in the 0 degree peeling test in the vertical direction (length direction).

The peeling energy in the 0 degree peeling test in the vertical direction (length direction) is preferably 200 N · mm or more, which can reduce the irritation given to the skin when the mouth breathing inhibitory tape 1 is peeled from the mouth. , A good feeling of use that is gentle on the skin can be achieved. The upper limit of the peeling energy in the 0 degree peeling test in the vertical direction (length direction) is 600 N · mm or less from the viewpoint that if the adhesive becomes too soft, it may cause stickiness or adhesive residue. Is preferable.

As described above, the mouth breathing inhibitory tape 1 of the present embodiment includes a base material 2 having a length and a width shorter than the length, and an adhesive layer 3 provided on the back surface of the base material 2. The maximum peeling force in the 0 degree peeling test in the length direction is 7 N or more, and the elongation rate in the length direction is 5% or more and 25% or less. Therefore, it is highly resistant to peeling from the mouth due to the vertical movement of the mouth during sleep (movement of the upper and lower lips separating) (difficulty of peeling), and the length direction that follows the vertical movement of the mouth. Since it has an appropriate elasticity, it cannot keep up with the vertical movement of the mouth and does not peel off from the mouth, and it does not stretch excessively in the length direction, so that the mouth breathing suppression tape 1 is attached to the mouth. It is possible to prevent the mouth from opening even in the open state. Therefore, according to the mouth breathing suppression tape 1 of the present embodiment, mouth breathing can be effectively suppressed.

Further, according to the mouth breathing suppression tape 1 of the present embodiment, since the average peeling force in the 180 degree peeling test in the length direction is 1N or more, the mouth breathing suppressing tape 1 comes into contact with the bedding during sleep and is rubbed by the bedding. However, it can be made difficult to peel off from the mouth.

Further, according to the mouth breathing inhibitory tape 1 of the present embodiment, since the peeling energy in the 0 degree peeling test in the length direction is 200 mm · N or more, the skin is stimulated when the mouth breathing inhibitory tape 1 is peeled off from the mouth. It can be suppressed, is gentle on the skin, and can improve the feeling of use.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment because the above embodiment is exemplary in all respects and is not limiting. Various modifications are possible as long as it does not deviate from the purpose of.

Hereinafter, the present invention will be described in more detail by way of examples. However, the mouth breathing inhibitory tape according to the present invention is not limited to the following examples.

The mouth breathing inhibitory tape of Example 1 has the shape shown in FIG. 1, and its dimensions are 41 mm in length, 19 mm in width (between the constrictions on both sides) to 23 mm (between the bulges on both sides), and 0 in thickness. It was .32 mm. A polyester spunlace non-woven fabric was used as the base material, and an acrylic pressure-sensitive adhesive was used as the pressure-sensitive adhesive. The mouth breathing inhibitory tape of Example 2 had a substantially bullet shape with a rounded tip, and its dimensions were 51 mm in length, 25 mm in width (the most swollen part), and 0.25 mm in thickness. Paper was used as the base material, and an acrylic pressure-sensitive adhesive was used as the pressure-sensitive adhesive. The mouth breathing inhibitory tape of Example 3 has the shape shown in FIG. 1, and its dimensions are 42 mm in length, 15 mm in width (between the constrictions on both sides) to 18 mm (between the bulges on both sides), and 0 in thickness. It was .30 mm. A polyester spunlace non-woven fabric was used as the base material, and a silicon-based pressure-sensitive adhesive was used as the pressure-sensitive adhesive. The mouth breathing inhibitor tape of the comparative example had a rectangular shape with rounded corners, and its dimensions were 51 mm in length, 20 mm in width, and 0.30 mm in thickness. A polyester spunlace non-woven fabric was used as the base material, and an acrylic pressure-sensitive adhesive was used as the pressure-sensitive adhesive.

Further, as the physical properties of the mouth breathing inhibitory tapes of Examples 1 to 3 and Comparative Examples, the maximum peeling force was measured by the 0 degree peeling test in the length direction of (1) above, and the elongation rate in the length direction of (2) above. And the average peeling force was measured by the 180 degree peeling test in the length direction of (3) above. Further, the peeling energy of the mouth breathing inhibitory tapes of Examples 1 and 2 was measured by the 0 degree peeling test in the length direction of (4) above. The results are shown in Table 1. FIG. 6 shows the behavior of the tensile force acting on the mouth breathing inhibitory tapes of Examples 1 and 2 from being pulled to being peeled from the test plate 10.

The mouth breathing suppression tapes of Examples 1 to 3 and Comparative Examples were subjected to a test (aiueo vocalization test) for confirming the difficulty of peeling due to the movement of the user's mouth. Specifically, the mouth breathing suppression tapes of Examples 1 to 3 and Comparative Examples were sequentially attached to the mouths of the same person so as to straddle the upper lip and the lower lip, and "A" and "I". I had them repeatedly say "U", "E", and "O". Then, the number of characters that could be uttered before the mouth breathing suppression tape was peeled off from the mouth or stretched out and became unusable was counted. The results are shown in Table 1. The results of the AIUEO vocalization test show that the larger the number of letters, the more difficult it is for the mouth breathing suppression tape to come off from the mouth due to the movement of the mouth.

In addition, for the mouth breathing suppression tapes of Examples 1 to 3 and Comparative Examples, a test (friction peeling durability test) for confirming whether or not the mouth breathing suppression tape is peeled off from the user's mouth by being rubbed by the bedding was conducted. went. Specifically, the mouth breathing suppression tapes of Examples 1 to 3 and Comparative Examples were sequentially attached to the arms of the same person at intervals, and as shown in FIG. 7A, the tape 1 was attached in the vertical direction (as shown in FIG. 7A). A skin rubbing test device manufactured by Needs Kiko Co., Ltd. with a semi-cylindrical (diameter 5 cm, height 5 cm, weight 60 g) friction terminal 13 in contact with one end in the (length direction) with the curved surface facing down. The 40 mm width was set to be rubbed at a pace of one reciprocating movement per second, and the tape 1 was slid toward the other end in the vertical direction (length direction) to reproduce the rubbing condition with the bedding. As shown in FIG. 7B, the friction terminal 13 has a structure in which a cotton cloth 15 is attached to the outer peripheral surface of an acrylic base 14 via a curing tape (not shown). After the friction terminal 13 reaches the other end of the tape 1 in the vertical direction (length direction), the friction terminal 13 is lifted from the tape 1 and returned to one end in the vertical direction (length direction), and then rubbed again. The terminal 13 was repeatedly slid toward the other end of the tape 1 in the vertical direction (length direction). Then, the number of times the friction terminal 13 was slid until the tape 1 was peeled off from the arm was counted. The results are shown in Table 1. The results of the friction peeling durability test show that the more times the mouth breathing suppression tape is peeled off from the mouth due to rubbing with the bedding.

In addition, the mouth breathing suppression tapes of Examples 1 and 2 were subjected to a test (a stratum corneum peeling test) for confirming the degree of irritation given to the skin when the mouth breathing suppression tape was peeled off. Specifically, after washing with soap and drying, the mouth breathing suppression tape is placed side by side on the arm of the same person, left to stand for 4 hours, then the mouth breathing suppression tape is peeled off, and the adhesive surface on the back surface is exposed to infrared rays. Measured using a spectrophotometer (IRAffinity-1S manufactured by Shimadzu Corporation), the amount of change in the peak corresponding to 1543 cm ^-1 was measured in comparison with the same type of mouth breathing inhibitor tape that was not attached to the skin. It was measured. The amount of change in this peak is proportional to the amount of stratum corneum peeled from the skin together with the mouth breathing inhibitor tape by removing the mouth breathing inhibitor tape from the skin. The results are shown in Table 1. The results of the stratum corneum peeling test show that the smaller the amount of change, the less irritation to the skin.

Furthermore, sensory evaluation was performed by having 20 monitors use mouth breathing suppression tape for 3 days each during sleep. The evaluation items were set as follows.

・ How the tape is peeled off when waking up 1. It wasn't peeled off.
2. 2. There was some peeling, but the mouth did not open.
3. 3. There was some peeling and the mouth was open.
4. It was completely peeled off.

・ Degree of pain when the tape is peeled off from the mouth 1. I didn't feel any pain.
2. 2. I felt a little pain.
3. 3. I felt pain.

Regarding the degree of tape peeling at the time of waking up, the number of people who selected 3 and 4 was counted as "the number of people who had tape peeling", and the occurrence rate was calculated. Regarding the degree of pain when the tape was peeled off from the mouth, the number of people who selected 2 and 3 was counted as the "number of people who felt pain", and the incidence was calculated. The results are shown in Table 2. The degree of peeling of the tape when waking up was subjected to sensory evaluation using the mouth breathing inhibitor tapes of Examples 1 to 3 and Comparative Examples, and the degree of pain when the tape was peeled from the mouth was the mouth of Examples 1 and 2. Sensory evaluation was performed using respiratory depression tape.

Referring to Tables 1 and 2, by comparison between Examples 1 to 3 and Comparative Example, the maximum peeling force in the 0 degree peeling test in the length direction is 7 N or more, and the elongation rate in the length direction is 5% or more. From the results of the AIUEO vocalization test and sensory evaluation, it was confirmed that the mouth breathing suppression tape, which is 25% or less, does not easily come off from the mouth even if there is movement of the mouth during sleep. In addition, by comparing Examples 1 and Examples 2 and 3, the mouth breathing suppression tape having a maximum peeling force of 30 N or more in the 0 degree peeling test in the length direction was found during sleep based on the results of the AIUEO vocalization test and sensory evaluation. It was confirmed that the mouth breathing suppression tape was more effectively difficult to peel off from the mouth even if there was movement of the mouth.

Referring to Table 1, by comparing Examples 1 and 2 with Examples 3 and Comparative Examples, the mouth breathing inhibitory tape having an average peeling force of 1 N or more in the 180-degree peeling test in the length direction was subjected to the friction peeling durability test. From the results, it was confirmed that the mouth breathing suppression tape was difficult to peel off from the mouth even if there was contact with the bedding during sleep. Further, by comparing Example 1 and Example 2, the mouth breathing inhibitory tape having an average peeling force of 3 N or more in the 180-degree peeling test in the length direction is different from the bedding during sleep based on the result of the friction peeling durability test. It was confirmed that the mouth breathing suppression tape was more effectively resistant to peeling from the mouth even when there was contact.

Referring to Tables 1 and 2, the mouth breathing inhibitory tape having a peeling energy of 200 mm · N or more in the 0 degree peeling test in the length direction by comparison between Examples 1 and 2 has a stratum corneum peeling test and a sensory evaluation. From the results, it was confirmed that the irritation given to the skin when the mouth breathing inhibitor tape was peeled off from the mouth was reduced.
