Description

  The present invention relates to a mask worn so as to cover both nostrils and mouth.

  When you catch a cold or get hay fever, you usually wear a mask to prevent cold outside air, outside bacteria, or pollen mixed in the atmosphere from entering the body. The mask is generally composed of a main body portion made of a flexible material such as a square planar gauze and ear hook straps attached to both sides of the main body portion. In addition to gauze, there are materials that use a resin nonwoven fabric or the like for disposable masks for surgery and various operations in addition to gauze. Covering the nose and mouth with the main body part and hanging the ear strap on both ears, the main body part is pulled left and right by the pulling force of the ear strap, and the main body part is deformed into a shape along the outer surface of the face, The nose and mouth are covered with the main body.

  In general, the mask is worn so as to cover the mountain-shaped nose, the cheeks that follow it, and the mouth. However, there is a drawback that the main body of the mask is displaced downward with the movement of the mouth and cheeks. When working in a food factory or in a dusty place or in an operation, both hands are blocked, and there is a problem that the shift of the lowering of the main body cannot be corrected.

  To correct this defect, insert a deformable member such as a wire near the upper edge or both side edges of the main unit, and deform the wire etc. by hand to match the outer shape of the nose or cheek. Is provided in close contact with the outer shape of the nose or cheek so that the main body does not slide downward. However, it takes a long time to shape by hand with a wire etc. inside the main body, and in addition, since the wire etc. is a rigid body, it may squeeze a part of the nose and give discomfort. is there.

  In addition, since the main body of the mask covers the user's nostril and mouth, the breath (sigh) discharged by the user himself rises along the inner surface of the mask. For this reason, when a user wears glasses, there is a problem that the lens of the glasses is fogged by his / her breath. Japanese Patent Laid-Open No. 2006-288650 (Patent Document 1) describes a portion above a nostril when a mask body having a size covering both the nostrils and the mouth is attached for the purpose of solving the above problem. It has been proposed to provide an adhesive layer.

  In this way, by sticking the adhesive layer provided on the body of the mask to the user's face, the increase in breathing is prevented, and as a result, the fogging of the glasses located above the mask is suppressed, The position can be prevented from shifting.

  However, when the adhesive is applied to the skin of the nose or cheek, there are problems that many users feel uncomfortable during use and cannot withstand long-time use. Moreover, when the mask is removed, some of the adhesive may adhere to the skin. To remove this adhesive, a special solvent must be used, which damages the skin tissue. There are things to do. In addition, once the adhesive is applied to the skin of the nose and cheeks, the adhesive strength is significantly reduced and cannot be used repeatedly, eventually a new mask must be used, which is uneconomical. There is also a problem.

JP 2006-288650 A

  The problem to be solved by the present invention is to provide a mask that prevents the main body from slipping down and can be repeatedly attached and detached by bringing the slip prevention sheet disposed on the main body into close contact with the back of the nose.

Therefore, the mask according to the present invention is a mask having a main body part that is worn so as to cover both nostrils and the mouth, and an ear strap for hanging on the ears on both sides of the main body part,
A flexible slip prevention sheet is disposed on the inner surface of the upper end side of the mask,
The slip prevention sheet has a substantially mirror-like surface so that at least part of the slip prevention sheet is in close contact with the back of the nose.

  The slip prevention sheet is formed of a thin sheet made of synthetic resin or synthetic rubber such as silicon, urethane, or styrene having flexibility, or natural rubber.

  In addition, an adhesive layer is formed of an adhesive or an adhesive on the inner surface side of the upper end of the slip prevention sheet and the mask, the adhesive layer is formed on the center side of the slip prevention member, and the upper end and the lower end are provided with the above The non-adhesion part in which an adhesive bond layer is not formed is provided.

  Further, the shift prevention sheet is fixed to the inner surface of the upper end of the mask by sewing or heat welding. The position for sewing or welding is preferably on both sides of the slip prevention sheet.

  According to the present invention, when the mask is attached, the flexible slip prevention sheet disposed on the inner surface on the upper end side comes into contact with the back of the nose, so that the mask does not shift downward and the position of the mask is stabilized. Can be made. The slip prevention sheet has a substantially mirror-like surface that contacts the back of the nose, so that at least a smooth part of the skin on the back of the nose is in close contact with the mirror surface of the slip prevention sheet, so that the downward shift is not caused. Is prevented. In addition, since the surface of the slip prevention sheet that contacts the back of the nose is free of pressure-sensitive adhesive or adhesive, there is little discomfort even when used for a long time, and part of the pressure-sensitive adhesive adheres to the skin. Nothing will happen. Further, even when the mask is repeatedly used a plurality of times or when the mask is washed, the close contact state does not decrease, which is economical.

  The slip prevention sheet is formed of a thin sheet made of synthetic resin such as silicon, urethane, styrene, or synthetic rubber, or natural rubber, and has flexibility, so it can flexibly correspond to the shape of the back of the nose, Discomfort during use can be eliminated.

  In addition, when the slip prevention sheet is disposed on the inner surface side of the upper end of the mask, the slip prevention sheet is formed with non-adhesive portions at the upper end and the lower end. Even if the adhesive is about to diffuse when it is brought into contact with the body, it prevents the adhesive from leaking out to the back of the nose due to the non-adhesive part, so it is possible to prevent user discomfort in advance. Become.

  Further, by fixing the slip prevention sheet to the inner surface side of the upper end of the mask by sewing or heat welding, it is possible to prevent uncomfortable feeling when the adhesive or adhesive comes into contact, and the adhesive. And the like are less likely to be detached due to peeling of the adhesive or the like, and can be firmly fixed.

  The mask has a main body part that is mounted so as to cover both nostrils and the mouth, and an ear strap for hanging on the ears on both sides of the main body part. A flexible slip prevention sheet is disposed on the inner surface of the upper end side of the mask. The slip prevention sheet has a substantially mirror-like surface so that at least part of the slip prevention sheet is in close contact with the back of the nose. The slip prevention sheet is formed of a thin sheet made of synthetic resin such as silicon, urethane, styrene, or synthetic rubber, or natural rubber, and has flexibility. In addition, the slip prevention sheet has an adhesive layer formed on the inner surface side of the upper end of the mask by an adhesive or an adhesive, and a non-adhesive portion in which the adhesive layer is not formed is formed on the upper end and the lower end of the slip prevention member. Thus, when the slip prevention sheet is brought into contact with the back of the nose, even if the adhesive is diffused, the non-adhesive portion is prevented from leaking to the back of the nose.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. A mask 1 shown in FIG. 1 includes a substantially rectangular main body 2 set to a size capable of covering both nostrils and mouth, and rubber 3 and 3 for ear hooks provided on both sides of the main body 2. It has. The main body 2 is made of a material having air permeability like a conventional mask and having a filter function for capturing dust and pollen. Nonwoven fabric is frequently used as such a material. As other materials, for example, artificial fibers such as gauze and synthetic fibers, paper, synthetic paper and the like can be adopted. These materials may be formed in multiple layers as necessary, or may be a laminated structure in which different materials are combined. The rubber 3 and 3 for the ear hook may be made of a heat-weldable material such as a resin nonwoven fabric.

  The main body 2 is provided with a plurality of folds 2a by folding along the long side in parallel, and both ends of the fold 2a are welded by strip-like members 2b and 2b made of a heat-weldable nonwoven fabric, for example. Restrained by bonding or sewing. The plurality of creases 2a are three-dimensionally formed so as to widen when worn and cover the mouth from the nose to the mouth and the jaw as shown in FIG. Reference numeral 4 denotes, for example, a wire that undergoes plastic deformation, and is inherently sealed by sealing the upper end side of the main body 2 in a bag shape by ultrasonic welding or the like.

  In the main body 2 of the mask 1, a slip prevention sheet 5 is provided on the inner surface at the upper end side in the center in the longitudinal direction. This slip prevention sheet 5 is formed by a thin sheet having flexibility made of a synthetic resin such as silicon, urethane, or styrene, synthetic rubber, natural rubber, or a polymer or elastomer. Incidentally, the slip prevention sheet 5 has a length in the longitudinal direction of 20 mm to 80 mm, preferably about 50 mm, and is formed in a rectangular shape having a width in the width direction of at least the central part of 10 mm to 30 mm, preferably about 15 mm. Further, the thickness of the slip prevention sheet 5 is 0.1 mm to 2.0 mm, preferably 0.5 mm.

  Further, the slip prevention sheet 5 is fixed to the upper end of the main body 2 by an adhesive layer 6 made of an adhesive or a pressure-sensitive adhesive. At this time, as shown in FIG. 3, it is desirable to fix the upper end of the slip prevention sheet 5 so as to coincide with the upper end of the main body 2. The adhesive layer 6 is formed on the center side in the width direction of the shift preventing portion sheet 5, and non-adhesive portions 6 a without an adhesive are formed on the upper end side and the lower end side. Further, the slip prevention sheet 5 has a substantially mirror surface on the surface opposite to the adhesive layer 6. This is because at least a part of the mask 1 is brought into close contact with the back of the nose when the user wears the mask 1. Note that the slip prevention sheet 5 may be fixed while being shifted downward from the upper end of the main body 2.

  As shown in FIG. 4, the mask 1 having the above-described configuration is worn so as to cover both the nostrils 7 and the mouth 8. At this time, the upper end of the main body 2 is positioned on the nose back 9, and the slip prevention sheet 5 contacts the nose back 9. The main body 2 is slightly pulled left and right by the rubber 3 for the ear hook, so that the center portion of the slip prevention sheet 5 comes into contact with the vicinity of the top of the nose dorsal portion 9 with a predetermined width W as shown in FIG. Both sides of the prevention sheet 5 come away from the cheeks or come into light contact. Since the skin of the nose spine portion 9 is approximately mirror-like by the nasal bone, the substantially mirror surface of the slip prevention sheet 5 surface and the mirror surface portion of the nose back portion 9 are brought into a surface-bonded state by contacting each other. Closely. As a result, the main body 2 of the mask 1 is prevented from slipping downward.

  As described above, when the mask 1 is worn, the slip prevention sheet 5 comes into contact with the back of the nose 9 with an appropriate pressure and is heated by the back of the nose 9. Even if the adhesive layer 6 of the slip prevention sheet 5 may flow somewhat due to heating, the non-adhesive portion 6a having no adhesive is formed on the upper end side and the lower end side. The nose back portion 9 is not reached, and the user is not uncomfortable. On the other hand, since both sides of the slip prevention sheet 5 are spaced apart from or lightly touched from the cheek, even if the adhesive flows, the user does not feel uncomfortable.

  When the mask 1 is repeatedly used, the surface of the slip prevention sheet 5 may be contaminated by oil or fat on the back of the nose 9 or sweat. In this case, since the surface is formed in a substantially mirror shape, it can be used as before by wiping with paper or cloth. That is, as long as the surface of the slip prevention sheet 5 and the back of the nose 9 can be surface-bonded and maintain a close state, the sheet can be used repeatedly.

  FIG. 6 shows an embodiment when applied to the three-dimensional mask 10. The three-dimensional mask 10 includes a substantially hemispherical main body 11 that is set to a size that can cover both nostrils and the mouth, and ear hooks 12 and 12 provided on both sides of the main body 11. The main body 11 is formed of a non-woven fabric having air permeability like a conventional mask and having a filter function for capturing dust and pollen. And the slip prevention sheet 13 is arrange | positioned by the inner surface in the upper end side of the center in the main-body part 11. As shown in FIG. As shown in FIG. 7A, the displacement prevention sheet 13 used for the three-dimensional mask 10 is formed in a mountain shape. This is because the upper end side of the main body portion 11 is formed in a substantially mountain shape, and the upper end side of the shift prevention sheet 13 is made to coincide with this upper end side.

  The slip prevention sheet 13 is also fixed to the upper end of the main body 11 by an adhesive layer 14 made of an adhesive or a pressure-sensitive adhesive. Also in this example, the adhesive layer 14 is formed on the center side in the width direction of the shift preventing portion sheet 5, and the non-adhesive portion 15 having no adhesive is formed on the upper end side and the lower end side. Further, the slip prevention sheet 13 has a substantially mirror surface on the surface opposite to the adhesive layer 14.

  Even with such a three-dimensional mask 10, when mounted so as to cover both nostrils and mouth, the slip prevention sheet 13 comes into contact with the back of the nose, and the approximate mirror surface of the slip prevention sheet 13 surface and the mirror surface portion of the back of the nose As in the above-described embodiment, the surfaces of the three-dimensional mask 10 are prevented from slipping downward as a result of being in close contact with each other and coming into close contact with each other.

  FIG. 7 shows a modification of the slip prevention sheet. That is, (A) shows the deviation preventing sheet 13 formed in a mountain shape as described above. (B) shows the prevention sheet 16 formed in an elliptical shape. Moreover, (C) shows the slip prevention sheet 20 formed into a three-dimensional shape in which the central portion is raised by, for example, foamed polyurethane, or a three-dimensional shape in which the inside is raised and the central portion is raised. In any example, the adhesive layers 14, 17, and 20 are formed on the center side in the width direction of the shift preventing portion sheet, and the non-adhesive portions 15, 18, and 21 without an adhesive are provided on the upper end side and the lower end side. Is formed. In addition, any slip prevention sheet has a substantially mirror surface on the surface opposite to the adhesive layer.

  FIG. 8 shows an example in which an anti-slip sheet is fixed by sewing to the inner surface on the upper end side at the center of the main body of the mask. In this embodiment, the slip prevention sheet 5 is sewn to the main body 2 of the mask 1 at both ends with a thread 30 such as cotton. In the example shown in FIG. 8, the gap at the upper end side of the slip prevention sheet 5 is narrow, the gap at the lower end side is wide, and the gap at the upper end side is substantially C-shaped so as to be larger than the width with which the nose dorsal portion 9 abuts. Sewing. In this way, by narrowing the gap on the upper end side, the shift between the shift preventing sheet 5 and the main body 2 that occurs when the main body 2 is lowered is reduced. By sewing in this way, the center portion comes into contact with the vicinity of the top of the nose back portion 9 and the sewing portions on both sides of the slip prevention sheet 5 are separated from the cheek or lightly touched, so that the thread 30 gives an uncomfortable feeling. There is no. Further, the center portion of the slip prevention sheet 5 is in close contact with the vicinity of the top of the nose back portion 9, and the main body portion 2 of the mask 1 is prevented from slipping downward in the same manner as in the above-described example. If the thread 30 for sewing the slip prevention sheet 5 is soft and does not feel uncomfortable even if it contacts the back of the nose 9, the periphery of the four sides of the slip prevention sheet 5 may be sewn. Further, when the slip prevention sheet 5 is used in combination with fixing with an adhesive or an adhesive, the sewing on both sides may be made parallel.

  FIG. 9 shows an example in which a slip prevention sheet is fixed to the inner surface on the upper end side at the center of the main body of the mask by heat welding. In this embodiment, the main body 2 of the mask 1 is made of a heat-weldable material such as a resin nonwoven fabric, and the slip prevention sheet 5 is also made of a heat-weldable material. The prevention sheet 5 is fixed to the main body 2 of the mask 1 at both ends by ultrasonic welding or the like. Also in this example, the gap on the upper end side of the slip prevention sheet 5 is narrow, the gap on the lower end side is wide, and the gap on the upper end side is welded in a substantially C shape so as to be larger than the width with which the nose spine portion 9 abuts. ing. In this manner, the gap between the slip prevention sheet 5 and the main body 2 is reduced by narrowing the gap on the upper end side as in the example of FIG. By welding in this way, the center portion of the slip prevention sheet 5 comes into contact with the vicinity of the top of the nose dorsal portion 9, and the welded portions 31 on both sides of the slip prevention sheet 5 are separated from the cheeks or lightly contacted with each other. Does not cause discomfort. Further, the center portion of the slip prevention sheet 5 is in close contact with the vicinity of the top of the nose back portion 9, and the main body portion 2 of the mask 1 is prevented from slipping downward in the same manner as in the above-described example. If the heat welding location of the slip prevention sheet 5 is flexible, or if the heat weld location is depressed and there is no sense of incongruity even if it contacts the back of the nose 9, the slip prevention sheet 5 4 Appropriate positions of the sides may be thermally welded. Further, when the slip prevention sheet 5 is used in combination with fixing with an adhesive or a pressure-sensitive adhesive, the welding on both sides may be made parallel as in the example of FIG.

  The above-described slip prevention sheet is formed into a thin sheet by a flexible material made of synthetic resin such as silicon, urethane, styrene, or polyurethane, or synthetic rubber, or natural rubber. As the slip prevention sheet, various materials can be mixed as well as a single material. For example, a silica mineral made of black silica or jammonstone, a mineral powder made of germanium powder, a capsaicin powder, or the like may be mixed with the above material. When these sub-materials are mixed, since the far-infrared rays are radiated, the back of the nose is appropriately heated, so that an effect of alleviating symptoms such as nasal congestion is obtained. Moreover, when sweating with capsaicin, the close contact between the slip prevention sheet and the back of the nose is improved by sweat, and the slip-off prevention effect can be further enhanced.
