Description

  The present invention relates to a mask having a main body part covering the nose, mouth and both cheeks, and in particular, the upper edge of the main body part is easily deformed according to the shape of the face, and both sides of the nose can be heated or kept warm. It is related with the mask which enabled this.

  A mask to be worn on the face is worn by a sick person or the like to prevent saliva scattering, and is further worn to prevent inhalation of pollen, dust or pathogens.

  In order to effectively prevent inhalation of pollen, dust or pathogen from the nose or mouth while wearing the mask, a structure in which a large gap is not formed between the main body of the mask and the face is desired.

  In the mask described in Patent Document 1 below, a body part that covers the nose, mouth, and both cheeks is formed of gauze or the like, and a nose part heat retaining part that protrudes upward from the upper edge of the body part is provided. When the main body portion is attached to the face, the nose portion and its periphery are three-dimensionally covered by the nose portion heat retaining portion. Moreover, the metal filament is provided toward the horizontal direction along the upper edge part of the said main body.

  The mask described in Patent Document 1 is easily installed at a position where the nose part heat retaining part covers the nose part and its periphery by pressing and deforming the metal strip along the horizontal curvature of the face. That's it.

  The mask described in Patent Document 2 has a main body that covers the nose, mouth, and both cheeks, and a pair of ear hooking rubbers that protrude from the main body to the left and right. A heat-generating composition that generates oxidation heat is stored inside the main body, and a temperature buffer material made of a nonwoven fabric, a porous sheet, or foamed plastic is provided on the inner side facing the face of the heat-generating composition. It has been.

JP 7-328135 A JP 2002-143330 A Microfilm of Japanese Utility Model No. 63-61752 (Japanese Utility Model Laid-Open No. 1-165053)

  The invention described in Patent Document 1 is provided with a nose part heat retaining part that protrudes upward from the main body part of the mask, and the nose part is three-dimensionally covered with this nose part heat retaining part, so the structure is complicated. In addition, since the mask itself has a three-dimensional shape, it is difficult to carry it away from the face. In addition, since the main body is deformed so as to follow the shape of the face by deforming the metal wire, there is an inconvenience that the metal wire cannot be folded unless the metal wire is bent after being removed from the face.

  The mask described in Patent Document 2 has a function of heating the air in the mask in addition to the original function of the mask, but the exothermic composition mainly composed of metal powder in the entire interior of the main body of the mask. In addition, since the temperature buffer material is housed, the mass of the main body becomes too large to be held on the face when it is attached to the face. In addition, since the entire area of the main body is hard, it is impossible to follow the shape of the face, and a gap is formed between the edge of the mask and the face, so that air warmed in the mask is likely to leak to the outside. There are drawbacks.

  In the mask described in Patent Document 3, the sheet material containing the base material of the aqueous patch is located at the center of the main body, and therefore the portion of the main body that stores the sheet material hits the nose. The main body is not easily deformed in the For this reason, a gap is easily formed between the edge of the mask and the face.

  The present invention solves the above-described conventional problems, and the upper edge of the main body portion is deformed following the shape of the face so that a gap is not easily formed between the upper edge and the face, and the entire softness of the main body portion is reduced. An object of the present invention is to provide a mask that is easy to put on the face without impairing the performance.

  Another object of the present invention is to provide a mask that can warm the air in the mask using a relatively small heating element, and that the air heated in the mask does not easily escape upward from the upper edge of the mask. It is said.

The present invention, in a mask having a body part covering the nose, mouth and both cheeks, and a pair of ear hooks extending laterally from the left and right sides of the body part,
The main body is provided with a reinforcing body having rigidity higher than that of the main body sheet forming the main body, and the reinforcing body is separated from the vertical center line that bisects the main body into the left and right sides. And it is partially provided in the position which approached the upper edge of the said main-body part, or the position which contact | connects an upper edge, It is characterized by the above-mentioned.

  In the present invention, the opposing side edge of the reinforcing body facing the vertical center line is located to the left and right away from the vertical center line, and the main body can be bent along the opposing edge. It has been done.

  In the mask of the present invention, reinforcing bodies are partially provided on both the left and right sides of the main body and in the upper position. When this reinforcement hits the face, the main body naturally bends at the opposite edge of the reinforcement, so the center of the main body covers the nose and the upper edge of the mask on both sides of the nose. It is difficult to form a gap between the face and the face.

  Preferably, in the present invention, the main body sheet is joined along the longitudinal center line in a state where the inner surfaces thereof face each other.

  When the main body part is joined along the vertical center line as described above, the central part of the main body part protrudes forward, and this part covers the nose in a three-dimensional manner. And since the said reinforcement body is located in the position left and right from the said longitudinal centerline, a main-body part is bend-deformed by a reinforcement body by the side of a three-dimensional center part. As a result, the upper edge of the main body portion follows the uneven shape of the face, and the gap between the upper edge of the main body portion and the face can be minimized.

  For example, in the present invention, the reinforcing body includes a heating element that generates heat when oxygen is applied. The reinforcing body is provided with a heat insulating layer covering at least one surface of the heating element.

  When the heating element is included in the reinforcing body, the portions of the sinuses on both sides of the nose can be warmed, and a user who suffers from allergic rhinitis or a cold can be given comfort. Since the reinforcing body itself is smaller than the main body, the mass of the main body does not become too large even if the heating element is provided. Further, since the upper edge of the main body portion easily follows the face shape, the air heated by the heating element is difficult to escape to the outside.

  However, in the present invention, the heating element may not be provided in the reinforcing body, and the reinforcing body may have an elastic sheet.

  In the mask of the present invention, the upper edge of the main body portion can easily follow the shape of the face when worn on the face, and the gap between the upper edge of the main body portion and the face can be minimized. Therefore, the mask can exhibit a sufficient dustproof effect, and the ability to prevent pollen and pathogens from entering can be increased. In addition, the mass of the main body itself does not increase, and it is difficult for the face portion to be displaced due to the weight.

  Further, the reinforcing body provided in the main body can exhibit a heat generation function, and this heat generation function can give a user a feeling of comfort for allergic rhinitis and colds.

  The area of each of the right main body sheet 21 and the left main body sheet 22 is 1/3 or less, preferably 1/4 or less, of the area of the right main body sheet 11 or the left main body sheet 12.

  The right side reinforcing body 21 and the left side reinforcing body 22 have a larger basis weight (basis weight) and higher rigidity than the right main body sheet 11 and the left main body sheet 12. Therefore, the main body 2 is easy to bend along the opposing edge portion 21a of the right reinforcing member 21 at a position left and right from the longitudinal center line OO by the distance W1, and the opposing edge of the left reinforcing member 22 is easily bent. It is easy to bend along the portion 22a.

  As shown in FIG. 4, the right-side reinforcing member 21 includes a heating element 31, a moisture-permeable heat insulating layer 32 that covers the inner surface on the face side of the heating element 31, and an outer heat insulating layer 33 that covers the outer surface of the heating element 31. ing. Similarly, the left reinforcing body 22 includes a heating element 31, a moisture-permeable heat insulating layer 32, and an outer heat insulating layer 33.

  The heating element 31 contains easily oxidizable metal powder such as iron, aluminum and zinc, water, and salts for oxidizing the metal powder. Examples of the salts include sodium chloride, potassium chloride, calcium chloride, and magnesium chloride. Further, in order to promote the oxidation of the metal powder, a carbon material such as activated carbon, carbon black, or graphite may be included. Furthermore, a moisturizing agent such as vermiculite, calcium silicate, silica gel, or silica may be included so that moisture can be retained for a long time.

  For example, the heating element 31 is a heating base containing iron powder, activated carbon, vermiculite, and wood powder containing 10% or more of salt water. When oxygen is given to the heating element 31, the heating element 31 generates heat due to the oxidation reaction of the metal powder, and the contained moisture evaporates to generate water vapor.

  The moisture-permeable heat insulating layer 32 relieves heat generated by the heating element 31. Further, the moisture-permeable heat insulating layer 32 can pass water vapor generated by the heating element 31. The moisture permeable heat insulating layer 32 is a foamed resin sheet such as foamed polyethylene or foamed polyurethane in which a large number of water vapor passage holes are formed. Alternatively, the moisture-permeable heat insulating layer 32 may be a laminate of a plurality of nonwoven fabrics.

  The outer heat insulating layer 33 is a foamed resin sheet that does not have water vapor passage holes, or a laminate of a plurality of nonwoven fabrics.

  The right side reinforcing body 21 and the left side reinforcing body 22 mean a portion where at least one of a heating element 31, a moisture-permeable heat insulating layer 32, and an outer heat insulating layer 33 is present. The shape of the reinforcing body 22 is determined by at least one of the heating element 31, the moisture-permeable heat insulating layer 32, and the outer heat insulating layer 33.

  The inner surfaces of the right side reinforcing body 21 and the left side reinforcing body 22 are covered with a common moisture permeable sheet 34. Further, the outer surface sides of the right side reinforcing body 21 and the left side reinforcing body 22 are covered with a common moisture-impermeable sheet 35. The moisture-permeable sheet 34 is a nonwoven fabric such as a spunlace nonwoven fabric, a point bond nonwoven fabric, a spunbond nonwoven fabric, or a through-air nonwoven fabric, and the moisture-impermeable sheet 35 is formed by laminating a resin film or a nonwoven fabric and a resin film. It has been done.

  In a state where the right-side reinforcing body 21 and the left-side reinforcing body 22 are sandwiched, the moisture-permeable sheet 34 and the non-moisture-permeable sheet 35 are bonded to each other or thermally welded to connect the two reinforcing bodies 21 and 22. The body is composed. An adhesive layer is applied to the outer surface of the non-moisture permeable sheet 35 facing the main body 2, and the connection body is formed on the inner surface of the right main body sheet 11 and the inner surface of the left main body sheet 12 constituting the main body portion 2. It is glued.

  The mask 1 is sealed in an outer bag that can block air. When taken out from the outer bag at the time of use, oxygen is supplied to the heating element 31 through the moisture-permeable sheet 34 and the moisture-permeable heat insulating layer 32, and the metal powder contained in the heating element 31 undergoes an oxidation reaction to generate oxidation heat. In addition, the moisture inside the heating element 31 is evaporated by this heat, and water vapor is released toward the face through the moisture-permeable heat insulating layer 32 and the moisture-permeable sheet 34.

6 and 7 show a state in which the mask 1 is mounted on the face.
The mask 1 covers the nose, mouth, and both cheeks with the main body 2, and the ear hooking hole 15 c of the right ear hooking sheet 15 and the ear hooking hole 16 c of the left ear hooking sheet 16 are attached to the respective ears. Is done.

  In an ideal wearing state on the face, the joint between the upper end 11c of the right main body sheet 11 and the upper end 12c of the left main body sheet 12 constituting the main body 2 is located above the top of the nose, and the right main body sheet 11 The upper edge 11e and the upper edge 12e of the left main body sheet 12 are respectively located directly under the eyes.

  In a state where the main body 2 is mounted on the face, the right side reinforcement body 21 and the left side reinforcement body 22 are installed at positions above both cheeks on both the left and right sides of the nose and directly below the eyes (near the sinuses). Since the right side reinforcing body 21 and the left side reinforcing body 22 have a predetermined area and have an inner surface facing the face, when the main body portion 2 receives the pulling force of the both ear hanging sheets 15 and 16, the right side reinforcing body 21 and the left side reinforcement body 22 become easy to adhere to the skin surface of the cheek. Since the right side reinforcement body 21 and the left side reinforcement body 22 are easily adhered to the face, a gap is hardly generated between the upper edge 11e of the right main body sheet 11 and the upper edge 12e of the left main body sheet 12 and the cheek.

  Further, as shown in FIG. 7, the main body portion 2 has the right side reinforcing body 21 due to the difference in rigidity between the right main body sheet 11 and the right side reinforcing body 21 and the difference in rigidity between the left main body sheet 12 and the left side reinforcing body 22. It becomes easy to bend so that it may become depressed toward the face along the opposing edge part 21a and the opposing edge part 22a of the left side reinforcement body 22.

  In the portion of the longitudinal center line OO, the portion of the joint line 13 between the central edge 11a and the central edge 12a protrudes forward to form a three-dimensional shape with a convex triangle as shown in FIG. Covered. Then, at both sides of the convex triangular solid shape, the main body 2 is bent along the opposing edge 21a of the right reinforcing body 21 and along the opposing edge 22a of the left reinforcing body 22 so that the face side is the mountain side. It is done.

  Therefore, the upper edge 11e of the right main body sheet 11 and the upper edge 12e of the left main body sheet 12 follow the uneven shape of the face, and it is difficult to form a gap between the upper edges 11e, 12e and the face. Therefore, the main body 2 of the mask 1 can enhance the effect of preventing entry of dust, pollen and the like from the outside.

  The heat generated from the heating element 31 provided on the right side reinforcing body 21 and the left side reinforcing body 22 is set to an appropriate temperature by the moisture-permeable heat insulating layer 32, and the vicinity of the sinuses on both sides of the nose is warmed. This warming can exert an effect of alleviating symptoms such as allergic rhinitis and cold. Further, water vapor generated from the heating element 31 is given into the main body 2 and an effect of relieving sore throat due to the humidification effect can be expected. As described above, since gaps are not easily formed between the upper edges 11e and 12e of the main body 2 and the face, air and water vapor heated in the main body 2 are difficult to escape to the outside.

FIG. 5 shows a second embodiment of the present invention.
In the mask 1A shown in FIG. 5, the right side reinforcing body 21A and the left side reinforcing body 22A do not have the heating element 31, and are more rigid than the main body sheets 11 and 12, and exhibit an elastic restoring force when bent. The elastic sheet 36 is formed. The elastic sheet 36 is formed of a foamed resin sheet such as foamed polyethylene or foamed polyurethane, a laminate of a plurality of paper materials, a laminate of a plurality of non-woven fabrics, or a laminate of the above materials. .

  When the mask 1A of the second embodiment is also attached to the face, as shown in FIG. 7, the right side reinforcing body 21A and the left side reinforcing body 22A are in close contact with the cheeks, and the opposing edges of the respective reinforcing bodies 21A and 22A It becomes easy to bend | fold so that the main-body part 2 may dent toward the face along the parts 21a and 22a. Therefore, a gap between the upper edges 11e and 12e of the main body 2 and the face is less likely to occur. As a result, it becomes easy to prevent dust and pollen from reaching the mouth and nose, and the effect of keeping the air between the main body 2 and the face can be exhibited.

  Further, when the right side reinforcing body 21A and the left side reinforcing body 22A are formed of a material containing air such as a foamed resin sheet or a non-woven fabric, the reinforcing bodies 21A and 22A cover the sinuses, thereby providing a sinus cavity. As a result, it can be expected to alleviate symptoms of allergic rhinitis and colds.
