  Symptoms such as allergic rhinitis and hay fever appear as sneezing, runny nose and nasal congestion. It is known that these symptoms are manifested by adhesion of allergens such as cedar pollen, dust, mites, exhaust gas, etc. scattered in the air to the mucous membrane in the nasal cavity.

As one of the measures to easily prevent, alleviate or eliminate these symptoms, a sheet-like mask body covering the periphery of the nose including the wearer's nasal cavity and the surface of the maxillary sinus, and upward from the center of the mask body There has been proposed a heat-retaining mask provided with a protruding portion that protrudes and covers the periphery of the surface of the ethmoid sinus between the wearer's eyes and ear hooks provided on the left and right sides of the mask body (Patent Document 1). .
JP 7-328135 A

  This thermal mask prevents allergies such as pollen from entering the nasal cavity with the mask body, while keeping the periphery of the nose including the maxillary sinus and the surface of the ethmoid sinus with the mask body and protrusions is allergenic. Prevent, alleviate or eliminate the onset of various symptoms such as rhinitis.

  However, the conventional heat-retaining mask has a structure in which a protrusion part separate from the mask body is provided inside the mask body (see FIG. 2 of the publication), the protrusion part is formed integrally with the mask body, and the protrusion A structure in which a metal wire having shape retention is provided from the peripheral portion of the mask to the upper edge portion of the mask body (see FIGS. 4, 6, and 8 of the same publication), and the protrusion is formed integrally with the mask body. , A structure in which a fold portion is provided in the vertical direction across the protrusion and the mask body (see FIG. 7 of the same publication), the protrusion is formed integrally with the mask body, and the protrusion and the mask body are A structure (see FIG. 9 of the same publication) that is hot-press molded into a three-dimensional shape covering the nose is employed.

  For this reason, when providing a projecting portion with a separate structure, as well as when providing a metal wire around the projecting portion, etc., when forming a pleated portion, further, hot-press molding the projecting portion into the shape of the nose. In any case, it becomes structurally complex, and although the number of processing steps increases and the production becomes cumbersome, a gap is formed between the face and the peripheral edge of the heat insulating mask when the heat insulating mask is attached, etc. The heat-retaining mask is difficult to fit on the face and lacks fit, and the heat-retaining effect is liable to be reduced.

  SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a three-dimensional mask that is easy to manufacture and excellent in heat retention, fit, and wearability.

  The present invention relates to a mask main body 1 for covering the periphery of the nose 6 including the wearer's nasal cavity 10 and the surface of the maxillary sinus 11, and the wearer's eyes 17 projecting upward from the center of the mask main body 1. The mask body 1 includes left and right main body sheet portions 8 in a mask including a protrusion 2 covering the periphery of the surface of the ethmoid sinus 18 and ear hooks 3 provided on both left and right sides of the mask main body 1. The mask body 1 is formed by joining at a substantially central joining edge 9 in the vertical direction, and the projecting part 2 is connected to the joining edge 9 by a projecting sheet part 18 integrally projecting upward from each body sheet part 8. It is comprised by joining at the joining edge 19 which does.

  In the mask main body 1 and the protrusion 2, the joint edges 9 and 19 are substantially omitted in side view so as to cover the wearer's chin 4, the nose apex 20, and the vicinity of the eye head 17 when worn. It may be arcuate. The mask body 1 and the projecting portion 2 cover the wearer's jaw 4 to the nasal apex 20 in a substantially arc shape at the time of wearing, and cover the portion from the nasal apex 20 to the vicinity of the eye head 17 in a substantially linear shape. The lower part of the joining edges 9 and 19 may be substantially arcuate in side view, and the upper part of the joining edges 9 and 19 may be substantially straight in side view.

  The mask body 1 may have a nostril covering portion 1A for covering the wearer's nostril 6a from below. The protrusion 2 may have a length that covers the peripheral portion of the wearer's eyebrow portion 36. The ear hook 3 has an upper side 13 and a lower side 14, and the tension of the upper side 13 may be larger than the tension of the lower side 14.

  A far infrared ray generation function may be added to the mask body 1 and / or the protrusion 2. A heat retaining sheet 27 or a warming sheet 29 may be provided inside the mask main body 1 and / or the protrusion 2. The outer mask 26 and the inner mask 27 may be detachable. A heat storage sheet 29 may be provided as the heating sheet.

  In the present invention, the mask body 1 is formed by joining the left and right body sheet portions 8 at the joint edge 9 in the vertical direction at the approximate center of the mask body 1, and the protruding portions 2 are integrally above the body sheet portions 8. Since the projecting sheet portion 18 projecting on the surface is joined by the joining edge 19 continuous to the joining edge 9, it is easier to manufacture than the conventional heat insulation mask, and the heat retaining property, fit property, and wearability Has the advantage of being excellent.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 to 5 illustrate a first embodiment of a three-dimensional mask for retaining the nose according to the present invention. As shown in FIGS. 1 to 3, the three-dimensional mask includes a mask main body 1, a protruding portion 2 protruding upward from the mask main body 1, and ear hooking portions 3 on both the left and right sides of the mask main body 1.

  When the wearer wears the mask on the face, the mask body 1 is sized to cover the jaw 4, mouth 5, nose 6, and the cheeks 7 on the left and right sides as shown in FIGS. It has a pair of left and right main body sheet portions 8 that are substantially symmetrical, and the two main body sheet portions 8 are overlapped and joined together by heat welding or the like at a substantially arc-shaped joining edge 9 in the vertical direction.

  The mask body 1 only needs to cover at least the periphery of the nose 6 including the surfaces of the nasal cavity 10 and the maxillary sinus 11. Each main body sheet portion 8 has a sheet member that prevents passage of pollen, which is a causative substance of allergic nasal inflammation, hay fever and the like, and has appropriate air permeability and heat retention, such as a synthetic resin having thermoplasticity. A nonwoven fabric sheet made of fiber is used.

  The ear hook part 3 has an upper side part 13 and a lower side part 14 at the upper and lower sides of the ear hole 12, and the base part is formed by heat welding or the like at the joint part 3 a in the vertical direction opposite to the joint edge 9 of each main body sheet part 8. It is joined. The upper side portion 13 and the lower side portion 14 are configured such that the tension of the upper side portion 13 is greater than the tension of the lower side portion 14 when the mask body 1 is applied to the face and the ear hooking portion 3 is hooked on the ear portion 15. Has been. A non-woven fabric sheet made of synthetic resin fiber having thermoplasticity is used for the ear hook 3.

  If the tension of the upper side portion 13 is greater than that of the lower side portion 14, the structure of the ear hook portion 3 is not a problem, but there is the following. For example, the width of the upper side portion 13 may be larger than that of the lower side portion 14, and the length of the upper side portion 13 may be shorter than that of the lower side portion 14. Moreover, you may make the upper side part 13 into a double structure, and you may provide another nonwoven fabric sheet inside the upper side part 13 by heat welding etc. in the front-back direction. The ear hook 3 may be formed with a slit and the slit 12 may be widened to form the ear hole 12 when the ear hook 3 is attached. The ear hook 3 may be integrally formed on the left and right sides of the mask body 1.

  The protrusion 2 protrudes upward from the central portion of the mask body 1 in the left-right direction with a predetermined width, and around the surface of the ethmoid sinus 37 between the nose bridge portion 16 of the wearer's nose 6 and the left and right sides of the eye 17. The wearer's nose 6 and its periphery are kept warm. The projecting portion 2 has a projecting sheet portion 18 projecting integrally from the main body sheet portion 8 on the center side of the mask body 1, and the pair of projecting sheet portions 18 are joined on the extension of the joining edge 9 on the mask body 1 side. Joined at the edge 19 by heat welding or the like.

  The mask body 1 and the projecting portion 2 are joined to each other so as to cover the wearer's face from the jaw portion 4 to the front of the mouth portion 5, through the nasal apex portion 20 and the vicinity of the vicinity of the head 17 in a substantially arc shape. The edges 9, 19 are formed in a substantially arc shape in a side view in the vertical direction, and when attached to the face, the joining edges 9, 19 exhibit a three-dimensional shape that projects forward in an arc shape at the approximate center of the left and right, 9 and 19 and the left and right sides thereof, a predetermined gap 21 is formed between the face and the face at an intermediate portion in the vertical direction excluding the space between the eye head 17 and the jaw 4.

  The left and right main body sheet portions 8 and the protruding sheet portions 18 are configured by integrally cutting a non-stereoscopic planar nonwoven sheet. In addition to the shape shown in FIG. 3, the upper edge of the mask body 1 and the side edge 18a of the protrusion 2 are recessed on the base side of the protrusion 2 as shown in FIGS. Any of a letter shape, an arc shape, or a straight line in an oblique direction may be used.

  The nonwoven fabric sheet constituting the mask body 1 and the protruding portion 2 uses a synthetic resin fiber nonwoven fabric kneaded with nano-powder, fine powder or the like of a far-infrared ray generating material. A far-infrared ray may be generated to give a warming effect to the face. Alternatively, negative ions may be generated by using synthetic resin fibers obtained by kneading tourmaline nano-powder, fine powder or the like in a nonwoven fabric sheet.

  When using this three-dimensional mask, as shown in FIG. 2 and FIG. 3, when the mask body 1 and the projecting portion 2 are applied to the face in a state where the mask body 1 and the protruding portion 2 are spread left and right, The mask body 1 can cover the entire mouth 5, the nose 6, and the left and right cheeks 7 from the jaw 4 including the surfaces of the nasal cavity 10 and the maxillary sinus 11. The nasal bridge portion 16 and its left and right sides to the surface periphery of the ethmoid sinus 37 between the eye head 17 can be covered.

  For this reason, not only the causative substances such as allergic rhinitis and hay fever can be blocked, but also the nasal cavity 10, the maxillary sinus 11 and the ethmoid sinus 37 around the face can be kept warm, and various symptoms such as allergic rhinitis and hay fever can be prevented. Can be relaxed or eliminated. In particular, not only the facial nasal cavity 10 and the maxillary sinus 11 but also the ethmoid sinus 37, which is an important heat-retaining site, can be kept at a constant temperature, so that the effect of alleviating or removing various symptoms such as allergic rhinitis and hay fever is great. It is.

  Moreover, this three-dimensional mask forms the mask main body 1 by joining the left and right main body sheet portions 8 with the joining edges 9 in the vertical direction, while the protruding sheet portions 18 projecting upward integrally from the respective main body sheet portions 8. Since a three-dimensional shape is formed by joining at a joining edge 19 continuous to one joining edge 9, it can be manufactured by joining two non-woven fabric sheets at joining edges 9 and 19 and cutting them into a predetermined shape, etc. It is simple and can be easily manufactured without any special increase in processing man-hours.

  Further, when the mask main body 1 and the projecting portion 2 are spread left and right, the upper side and the lower side are bent from the state before wearing shown by the two-dot chain line in FIG. Then, in this state, when the left and right ear hooks 3 are put on the ears 15 by hitting the face, the upper and lower sides of the mask body 1 are pulled to the left and right sides by the ear hooks 3 and drawn along the face. At the same time, the protrusion 2 is pressed against the face side.

  For this reason, it is difficult to form a gap between the mask main body 1 and the peripheral edge of the protrusion 2 at the time of wearing, despite the fact that there is a protrusion 2 protruding upward at the center of the mask main body 1. Improves.

  Moreover, since the tension of the upper side 13 of the ear hook 3 is greater than the tension of the lower side 14, the upper side of the mask body 1 including the protrusion 2 can be reliably fitted to the face. It is possible to eliminate the downward shift due to the movement of the muscles of the face.

  Incidentally, when the tension of the ear hook 3 was measured using a predetermined test mask, a result as shown in FIG. 5 was obtained. The measurement method is to measure the value when three wearers wear a test mask, apply spring springs to the upper side 13 and the lower side 14 of the ear hook 3 and pull 3 cm away from the face. did. Each numerical value in FIG. 5 is measured three times for each of the upper side portion 13 and the lower side portion 14 and indicates an average value thereof. Note that the left and right numerical values are different depending on whether the wearer is right-handed or left-handed, and the value of the dominant hand tends to increase. Moreover, when a wearer is a man, a numerical value is large because the face is large. The unit is g.

  Thus, by configuring the ear hook 3 so that the tension of the upper side 13 is larger than that of the lower side 14 in the wearing state, the pressing force of the mask body 1 and the protrusion 2 against the face increases, and the fit property Has been confirmed to improve.

  Further, the joining edges 9 and 19 of the mask body 1 and the projecting part 2 are formed so as to cover the wearer's jaw part 4 through the nose apex part 20 and the vicinity between the eyes 17 in a substantially arc shape. Since it is substantially arcuate in side view, a predetermined heat insulating space can be secured between the joint edges 9 and 19 and the left and right sides of the face, thereby improving heat retention.

  6 and 7 illustrate a second embodiment of the present invention. In this three-dimensional mask, the joint edges 9 and 19 of the mask main body 1 and the protruding portion 2 are formed in a substantially arc shape in a side view from the jaw portion 4 of the wearer's face through the front of the mouth portion 5 to the nasal apex portion 20. The portion from the nasal apex 20 to the vicinity of the head 17 is substantially linear. Other configurations are the same as those of the first embodiment.

  In this way, the vicinity from the top of the nose 20 to the vicinity of the eye head 17 may be substantially linear. In this way, when the mask body 1 is spread left and right and attached to the face, the nose on the top of the mask body 1 changes from the state before the two-dot chain line to the solid state as shown in FIG. A portion including the upper protruding portion 2 is curved and drawn from the portion corresponding to the top portion 20 to the face side, and the protruding portion 2 is in a state along the nose bridge portion 16 of the wearer. For this reason, when the joint edge 19 etc. of the protrusion part 2 protrudes forward, the amount of protrusion will become small, and visual discomfort such as becoming an obstacle to a wearer's visual field can be eliminated as much as possible.

  8 and 9 illustrate a third embodiment of the present invention. In this three-dimensional mask, the projecting portion 2 extends between the wearer's eyes 17 and the vicinity of the forehead portion 36 of the forehead and covers the entire nose portion 6 to the periphery of the eyebrows portion 36. . The other configurations are the same as in the second embodiment, but the joint edges 9 and 19 on the lower side from between the heads 17 are the same as in the first embodiment, as in the first embodiment. Also good.

  In this case, the protrusion 2 can reliably keep the ethmoid sinus 37 between the eye heads 17 up to the upper end side. In addition, the upper end part of the protrusion part 2 is provided with a curved part 22 whose upper side curves from the wearer's eye head 17 along the forehead to the front side.

  10-13 illustrate a fourth embodiment of the present invention. In this three-dimensional mask, as shown in FIGS. 10 to 12, the mask main body 1 covers the upper side from the middle of the wearer's nose 6 and mouth 5, and the mask main body 1 A nostril covering portion 1A that covers the nostril 6a from below is formed. Further, since the lower end of the nostril covering portion 1A is the length between the nose portion 6 and the mouth portion 5 of the wearer, on the lower side of the joint edge 9, as shown in FIG. The non-joining part 9a which has not joined 8 is provided. Other configurations are the same as those in any of the first to third embodiments.

  In this case, when worn, the nostril covering portion 1A at the lower part of the mask body 1 is bent and drawn downward below the nostril 6a to cover the nostril 6a from below. For this reason, invasion of pollen or the like into the nostril 6a can be prevented, and the front side of the mouth portion 5 is opened, so that the uncomfortable feeling of wearing the mask during conversation or the like can be eliminated. Of course, the wearer's nasal cavity 10, maxillary sinus 11, ethmoid sinus 37, etc. can be kept warm at the same time. In addition, since there is a non-joined portion 9a where the main body sheet portion 8 is not joined to the lower end portion, there is no fear that the face is damaged at the edge of the joined edge 9.

  It should be noted that the lower portion of the nostril covering portion 1A between the nose portion 6 and the mouth portion 5 at the lower end of the mask body 1 is provided with a curved portion 23 bent in the frontward direction as shown in FIG. The curved portion 23 may be in contact between the nose portion 6 and the mouth portion 5 when it is provided and attached to the face.

  FIG. 14 illustrates a fifth embodiment of the present invention. In this three-dimensional mask, as shown in FIG. 14, a pair of left and right shape-retaining bodies 24 are provided substantially symmetrically at appropriate locations such as the upper part on the front side of the mask body 1. In FIG. 14A, a shape retaining body 24 is provided along the edge between the upper end portion of the protruding portion 2 and the upper end portion of the joint portion 3 a of the ear hook portion 3. In FIG. 14B, a shape retaining member 24 is provided at an intermediate portion between the upper end portion of the mask body 1 and the protruding portion 2. The shape-retaining body 24 is suitably a tape-like material made of a polyolefin-based synthetic resin having a molecular arrangement arranged in a uniaxial direction, or one provided with one or a plurality of metal wires. The shape retaining body 24 may be provided on the inner surface side of the mask main body 1. The shape retainer 24 may be covered with a nonwoven fabric or the like.

  In this way, the shape retaining body 24 is bent along the concavo-convex shape on both sides of the nasal bridge portion 16 by pressing the portion of the shape retaining body 24 from the front side to the face side after mounting, etc. The fit of the upper side can be further improved.

  FIG. 15 illustrates a sixth embodiment of the present invention. In this embodiment, a heating part 25 made of a far infrared ray generating material or the like is formed on the inner surfaces of the mask main body 1 and the protruding part 2. In FIG. 15A, the heating portion 25 is formed in a planar shape over substantially the entire inner surface, and in FIG. 15B, the heating portion 25 is formed in a number of streaks over substantially the entire inner surface. In FIG. 15C, a heating portion 25 is formed in a specific part so as to correspond to the left and right sides of the nasal bridge portion 16 and the maxillary sinus 11. The heating unit 25 is prepared by kneading nanopowder, fine powder, or the like such as a far infrared ray generating material with a binder as appropriate.

  In addition to kneading the far-infrared ray generating material into the synthetic resin fiber of the non-woven sheet, even if the heating part 25 is formed by coating the nano-powder, fine powder, etc. of the far-infrared ray generating material in this way, The face can be heated by the part 25. And by warming the face, various symptoms such as allergic rhinitis and hay fever can be effectively alleviated or removed.

  When the nonwoven fabric sheet is a thermoplastic resin fiber, nanopowder or fine powder such as far-infrared ray generating material may be dispersed on the nonwoven fabric sheet, and then heat fusion may be performed by applying heat at a predetermined temperature. In this case, there is an advantage that the filter effect is improved due to the fineness of the nonwoven fabric sheet due to heat fusion. In addition, nanopowder such as tourmaline or fine powder may be heat-sealed.

  16 and 17 illustrate a seventh embodiment of the present invention. In this embodiment, a similar inner mask 27 having a mask main body 1a and a protruding portion 2a is provided inside an outer mask 26 having a mask main body 1, a protruding portion 2 and an ear hooking portion 3.

  Both the outer mask 26 and the inner mask 27 have a three-dimensional shape. The inner mask 27 constitutes a heat insulating sheet, and is detachably attached to the inner side of the outer mask 26 via an adhesive 28 so that a predetermined gap is formed between the inner mask 27 and the outer mask 26. The adhesive 28 is provided at both end portions of the mask main body 1a of the inner mask 27 and other required portions.

  Thus, if the outer mask 26 and the inner mask 27 have a double structure, the prevention effect of pollen and the like is improved, and the heat retention is improved, so that various symptoms such as hay fever are more effectively reduced or removed. can do. In addition, since the inner mask 27 is detachably attached to the outer mask 26, the inner mask 27 that is easily soiled by exhalation or the like can be replaced and used.

  The outer mask 26 and the inner mask 27 may be composed of the same or different nonwoven fabric sheets, or one of them may be composed of a woven fabric such as gauze or the like. When providing a heat insulation sheet, you may provide partially in required places, such as the mask main body 1 and the protrusion part 2 of the side which has the ear hook part 3. FIG. Further, it is desirable that the heat insulating sheet is detachable.

  18-20 illustrate an eighth embodiment of the present invention. In this embodiment, as shown in FIGS. 18 and 19, a heat storage sheet 29 for heating is provided in a part of the mask main body 1 and / or the protruding portion 2 and the like so as to be detachable substantially symmetrically. . As shown in FIG. 20, the heat storage sheet 29 is formed in a sheet shape by enclosing a gel-like heat storage agent 31 such as CMC, PVA, acrylic acid polymer or the like in a sealing bag 30. It is detachably provided via the agent 32 or the like.

  In this case, if the heat storage agent 31 is stored on the face with the heat stored, the necessary part of the face can be heated by the heat, and the heating effect is remarkably improved. In addition, if the thermal storage sheet 29 is provided in the location which contacts a face, since the body temperature from a face will be transmitted to the thermal storage sheet 29, the thermal storage time of the thermal storage sheet 29 can be maintained long. When the three-dimensional mask is discarded, the heat storage sheet 29 may be peeled off and reused.

  The heat storage sheet 29 may be provided so as not to be peeled off. Further, the heat storage sheet 29 may be provided corresponding to the maxillary sinus 11.

In this embodiment, as shown in FIGS. 21 and 22, a part of the mask main body 1 and / or the protrusion 2 and the like correspond to the left and right sides of the nasal bridge portion 16 including the ethmoid sinus 37, for example. A warming sheet-like warmer 33 is mounted and sealed in a sealed bag 34 having a gas barrier property.

  The warmer 33 constitutes a heating sheet, which is formed by filling a ventilation bag 38 with a heat generating powder 35 made of iron powder or the like, and is mounted inside via a hot melt agent or the like. As shown in FIG. 23, this warmer 33 forms a pocket between the nonwoven fabric sheet 1b such as the mask body 1 and the holding sheet 1c attached to the inside thereof, and the heating powder 35 is placed in the pocket. It may be filled. The holding sheet 1c may be air permeable or non-air permeable.

  At the time of use, the airtight bag 34 is opened by, for example, breaking the breaking portion 34a, the three-dimensional mask is taken out, and the three-dimensional mask is mounted on the face. Then, the exothermic powder 35 of the warmer 33 reacts with oxygen in the air to generate heat, and for example, corresponding portions such as the left and right sides of the nasal bridge portion 16 including the ethmoid sinus 37 can be heated. The warmers 33 may be provided corresponding to other locations, for example, the maxillary sinus 11, or may be provided corresponding to the left and right sides of the nasal bridge part 16 including the ethmoid sinus 37 and the maxillary sinus 11.

  As mentioned above, although each Example of this invention was explained in full detail, it is not limited to each Example, A various change is possible in the range which does not deviate from the meaning of this invention. For example, the mask main body 1 and the protruding portion 2 may be a non-woven fabric sheet other than synthetic resin fibers, or may be configured using a sheet material such as woven fabric or paper having air permeability other than the non-woven fabric sheet.

  Further, the joining edges 9 and 19 of the mask body 1 and the protruding portion 2 may be joined by joining means other than heat welding, for example, adhesion.
