  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 to 7 illustrate a first embodiment of a disposable three-dimensional mask and a disposable three-dimensional mask enclosure according to the present invention. As shown in FIGS. 1 to 4, the disposable three-dimensional mask has a mask body 3 formed by joining a pair of left and right nonwoven fabric sheets 1 at joining edges 2, and a pair of left and right ears provided on the left and right sides of the mask body 3. A hanging portion 4 and a heat generating sheet 5 provided on each nonwoven fabric sheet 1 of the mask body 3 are provided.

  The mask main body 3 has a main cover portion 6 and a protruding cover portion 7 protruding in a mountain shape upward from a central portion in the left-right direction of the main cover portion 6. As shown in FIGS. 2 and 3, the main cover 6 includes the surfaces of the nasal cavity 8 and the maxillary sinus 9 when the wearer wears on the face, and from the jaw portion 10 of the face to the mouthpiece portion 11 and the nose portion 12. And the projecting cover 7 has a size that covers the entire cheek 13 on both the left and right sides thereof, and the projecting cover 7 is the middle of the nose bridge 14 of the wearer's nose 12 and the ethmoid sinus between the left and right sides and the head 15 It covers up to 16 surface periphery.

  The mask body 3 is formed by superposing a pair of left and right nonwoven fabric sheets 1 having a substantially symmetrical shape, and the pair of nonwoven fabric sheets 1 is formed in a substantially arc shape by a joint edge 2 in the vertical direction at the approximate center in the left and right direction of the mask body 3. It is integrally joined to.

  The mask body 3 is sized to cover the jaw part 10, the mouth part 11, the nose part 12 and the cheek parts 13 on the left and right sides thereof, but at least the middle part in the vertical direction of the nose bridge 14 from the mouth part 11 and the left and right parts. What is necessary is just to be able to cover the cheek part 13 of both sides. The joining edge 2 is configured by heat welding or the like.

  Nonwoven fabric sheet 1 is a non-woven fabric made of synthetic resin fibers that prevents passage of pollen, etc., which is a causative substance of allergic rhinitis and hay fever, and has appropriate air permeability and heat retention, for example, thermoplastic resin synthetic fiber. Sheets are being used.

  In addition, it is desirable that the non-woven fabric sheet 1 is joined at the joining edge 2 between the non-joining portions 2a so that the non-joining portions 2a are formed at the upper and lower ends of the mask body 3. This is because the joint edge 2 does not damage the wearer's face or the like. In addition, when the lower end of the main cover part 6 protrudes downward from the jaw part 10, you may provide the joining edge 2 to the lower end.

  As a nonwoven fabric of synthetic resin fiber having thermoplasticity, for example, a nonwoven fabric made of a single fiber such as an olefin resin fiber, a polyethylene resin fiber, a polyester resin fiber, a polypropylene resin fiber, a nonwoven fabric made of a composite core-sheath fiber, or A laminated composite nonwoven fabric or the like can be used. As the composite core-sheath fiber, polyester-polyethylene core-sheath fiber, polypropylene-polyethylene core-sheath fiber, or the like can be applied. As the laminated composite nonwoven fabric, a laminated nonwoven fabric of cotton and polyethylene, a laminated nonwoven fabric of rayon and polyethylene, a laminated nonwoven fabric of cotton and polypropylene, and the like can be applied. The same applies to the nonwoven fabric used for the heat generating sheet 5.

  The mask body 3 is obtained by joining a flat nonwoven fabric sheet 1 having no three-dimensionality at a substantially arc-shaped joining edge 2 and then cutting the periphery integrally. The joint edge 2 has a three-dimensional shape projecting forward in a circular arc shape when spread to the front, and on the joint edge 2 and its left and right sides, the face and A predetermined gap is formed between the two.

  The ear hook part 4 has an upper side part 18 and a lower side part 19 above and below the ear hole 17, and the base part is joined by thermal welding or the like at the joint part 20 in the vertical direction opposite to the joint edge 2 of each nonwoven fabric sheet 1. Has been. The upper side portion 18 and the lower side portion 19 are configured such that the tension of the upper side portion 18 becomes larger than the tension of the lower side portion 19 when the mask body 3 is applied to the face and the ear hooking portion 4 is hung on the ear portion 21. Has been. A non-woven fabric sheet made of synthetic resin fiber having thermoplasticity is used for the ear hook 4.

  If the tension of the upper side portion 18 is larger than that of the lower side portion 19, the structure or the like of the ear hook portion 4 is not a problem, but there is the following. For example, the width of the upper side portion 18 may be larger than that of the lower side portion 19, and the length of the upper side portion 18 may be shorter than that of the lower side portion 19. Moreover, you may make the upper side part 18 into a double structure, and you may provide another nonwoven fabric sheet in the front-back direction inside the upper side part 18, for example by heat welding. The ear hooking portion 4 may be provided with a slit, and when the ear hook is attached, the slit may be widened to form the ear hole 17. The ear hooking portion 4 may be provided integrally on both the left and right sides of the mask body 3.

  The heat generating sheet 5 constitutes a heating sheet for heating the nasal cavity 8 and the surface side of the ethmoid sinus 16 from the side of the nose bridge 14 of the wearer's nose 12 to the vicinity of the eye head 15. For example, as shown in FIGS. 5 and 6, the heat generating sheet 5 is filled in a front sheet 22 and a back sheet 23 made of non-woven fabric whose outer periphery is sealed by heat welding or the like, and an internal space between both the sheets 22 and 23. A heat generating powder 24 mainly composed of iron powder and a sticking adhesive portion 25 provided on the back side of the back sheet 23, the inner surface of the nonwoven fabric sheet 1 in the vicinity of both sides of the joining edge 2 of the mask body 3. When the adhesive part 25 is attached to the face, a predetermined gap is formed between the face and the face of the wearer, or a flexible sheet having a thickness that allows light contact is formed.

  Note that the heat generating sheet 5 has a heated portion such as the surface of the nasal cavity 8 and the ethmoid sinus 16 that is equal to or slightly higher than the body temperature due to reaction heat generated when the heat generating powder 24 comes into contact with air and undergoes an oxidation reaction. Heat is generated by heating at a low temperature such as about 38 ± 2 ° C. The adhesive portion 25 is formed of an adhesive applied to substantially the entire back surface of the back sheet 23 and is protected by a release paper 26.

  The heat generating sheet 5 is housed in a sealed bag 27 having a gas barrier property as a set of two sheets, taken out from the sealed bag 27 in use, peeled off the release paper 26, and attached to the nonwoven fabric sheet 1 through the adhesive portion 25. . The side corresponding to the joining edge 2 side of the heat generating sheet 5 and the upper end edge of the projecting cover portion 7 has a shape along the joining edge 2 side and the upper end edge of the projecting cover portion 7.

  In addition, the adhesion part 25 is comprised by the hot-melt pressure sensitive adhesive, for example. The hot melt pressure sensitive adhesive is made of an adhesive mixture based on a thermoplastic polymer and containing no solvent or water. Of course, other adhesives may be used for the adhesive portion 25.

  The front sheet 22 and the back sheet 23 are made of a nonwoven fabric made of thermoplastic fibers having air permeability, and the peripheral edges thereof are sealed by heat welding or the like. The back sheet 23 may be a thermoplastic film. The front sheet 22 may be a film in which a large number of micropores are formed. Further, by encapsulating the heat generating sheet 5 in the sealing bag 27, a heat generating sheet enclosing body for a disposable three-dimensional mask configured as shown in FIGS. 5 and 6 is configured.

When using this three-dimensional mask, the heat generating sheet 5 is taken out from the sealing bag 27, and the heat generating sheet 5 is attached to the inner surface side of the nonwoven fabric sheet 1 in the vicinity of both sides of the joining edge 2 of the mask body 3. In this case, if the non-woven sheet 1 of the mask body 3 is spread left and right, the exothermic sheet 5 is adhered to the non-woven sheet 1 via the adhesive portion 25 while aligning one side edge of the exothermic sheet 5 with the joining edge 2. The heat generating sheet 5 can be easily attached to a predetermined position of the nonwoven fabric sheet 1.

  After sticking the heat generating sheet 5 to each non-woven fabric sheet 1, as shown in FIGS. 2 and 3, the left and right non-woven fabric sheets 1 are spread on both sides and faced to the face. The main cover 6 can cover the entire mouthpiece part 11, the nose part 12 and the left and right cheeks 13 from the jaw part 10 including the surfaces of the nasal cavity 8 and the maxillary sinus 9 with the main cover part 6, and the protruding cover part. 7 can cover the nasal bridge 14 of the nose 12 and the left and right sides thereof to the surface periphery of the ethmoid sinus 16 between the head 15. Moreover, the surfaces of the nasal cavity 8 and the ethmoid sinus 16 can be heated on both sides of the nasal bridge 14 of the nose 12 by the left and right heat generating sheets 5.

  Accordingly, not only the causative substances such as allergic rhinitis and hay fever can be blocked, but also the periphery of the nasal cavity 8, the maxillary sinus 9 and the ethmoid sinus 16 of the face are kept warm, and at the same time, the periphery of the nasal cavity 8 and the ethmoid sinus 16 are kept at a predetermined temperature. Since it can be heated, various symptoms such as allergic rhinitis and hay fever can be alleviated or eliminated. In particular, since not only the periphery of the nasal cavity 8 on the face but also the periphery of the ethmoid sinus 16, which is an important heating site, can be uniformly heated, the effect of alleviating or removing various symptoms such as allergic rhinitis and hay fever is great. .

  Even in the mounted state, as shown in FIGS. 3 and 4, there is a gap between the mask body 3 and the face on the lower side except the upper end of the protruding cover 7, and the gap becomes a heat insulation space and a heat insulation space. The heat retention effect is very good. And although the heat generating sheet 5 is provided inside the nonwoven fabric sheet 1, since the sheet-shaped heat generating sheet 5 is stuck inside the nonwoven fabric sheet 1 in the gap part used as heat insulation space and heat insulation space, the heat generating sheet 5 is Without being in close contact with the wearer's face, combined with the relatively low heat generation temperature of the heat generating sheet 5, it is possible to prevent low-temperature burns and the like on the heated portion of the face.

  Since the heat generating sheet 5 is detachably attached to the inner surface side of the nonwoven fabric sheet 1 by the adhesive portion 25, it is easy to attach to the nonwoven fabric sheet 1, and if the heating effect of the heat generating sheet 5 is reduced, The old heat generating sheet 5 can be peeled off and easily replaced with a new one. Therefore, even if the heating effect of the heat generating sheet 5 is reduced, it is not necessary to discard the three-dimensional mask itself, and the three-dimensional mask can be used repeatedly for a certain period.

  Since this three-dimensional mask is formed in a three-dimensional shape having a main cover portion 6 and a protruding cover portion 7 by joining the left and right nonwoven fabric sheets 1 with a substantially arc-shaped joining edge 2 in the vertical direction, the two-layer nonwoven fabric sheet 1 Can be manufactured by joining them at the joint edge 2 and cutting them into a predetermined shape, etc., and can be easily manufactured without any special increase in the number of processing steps.

  Moreover, when the nonwoven fabric sheet 1 of the mask main body 3 is spread left and right, the upper side and the lower side are curved 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 4 are put on the ears 21 against the face, the upper and lower sides of the mask body 3 are pulled to the left and right sides by the ear hooks 4 and drawn along the face. The peripheral edge is pressed against the face side.

  For this reason, although the mask main body 3 has a shape including a protruding cover portion 7 protruding upward at the center of the main cover portion 6, there is a gap between the peripheral edge portion of the mask main body 3 and the face when worn. It becomes difficult to do, and heat retention and fit are improved.

  Moreover, since the tension of the upper side portion 18 of the ear hooking portion 4 is larger than the tension of the lower side portion 19, the upper side of the mask body 3 including the protruding portion can be securely fitted to the face, and in the wearing state. It is possible to eliminate a downward shift or the like due to facial muscle movement or the like.

  Incidentally, when the tension of the ear hook 4 was measured using a predetermined test mask, the result shown in FIG. 7 was obtained. The measurement method is to measure the value when three wearers wear a test mask, apply spring springs to the upper side 18 and lower side 19 of the ear hook 4 and pull 3 cm away from the face. did. Each numerical value in FIG. 7 is measured three times for each of the upper side portion 18 and the lower side portion 19 and indicates an average value. 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 hooking portion 4 so that the tension of the upper side portion 18 is larger than the lower side portion 19 in the mounted state, the pressing force against the face of the peripheral edge portion of the mask body 3 is increased, and the fit is improved. It was confirmed that it improved further.

  8-10 illustrate a second embodiment of the present invention. In this three-dimensional mask, as shown in FIGS. 8 and 9, the mask body 3 has a multilayer structure, and a heat generating sheet 5 is interposed between the layers. The mask main body 3 has a multilayer structure including an outer mask portion 30 and an inner mask portion 31 disposed inside the outer mask portion 30.

  Each mask part 30, 31 is configured by joining left and right nonwoven fabric sheets 1 with arcuate joining edges 2, and ear hooking parts 4 are provided at both ends of the outer mask part 30 via joining parts 20. The inner mask portion 31 is slightly smaller than the outer mask portion 30.

  The inner mask portion 31 has vertical adhesive portions 32 at both left and right ends, and a small space is provided between the inner mask portion 31 and the outer mask portion 30 so that the adhesive portions 32 at both ends are detachably attached to the inner surface side of the outer mask portion 30. It is worn. And in the space between the outer mask part 30 and the inner mask part 31, a sheet-like heat generating sheet 5 for heating a heated part such as the surface of the wearer's ethmoid sinus 16 can be put in and out separately on the left and right sides. Has been inserted.

  It is desirable that the gap between the two when the inner mask portion 31 is attached to the outer mask portion 30 is set to such an extent that the heating sheet 5 is difficult to move. The inner mask portion 31 may be fixed to the inner side of the outer mask portion 30 at both left and right end portions by heat fusion or the like.

  As shown in FIG. 10, the heat generating sheet 5 is enclosed in a sealing bag 27 in pairs. Unlike the first embodiment, the heat generating sheet 5 does not include the adhesive portion 25, the release paper 26, and the like. Other configurations are substantially the same as those of the first embodiment.

  In use, the outer mask part 30 and the inner mask part 31 are expanded to the left and right to form a three-dimensional shape, and the inner mask part 31 is adhered to the inner side of the outer mask part 30 via the adhesive part 32, so A mask body 3 having a multilayer structure is formed. And the exothermic sheet 5 taken out from the sealing bag 27 is inserted into the space between the outer mask portion 30 and the inner mask portion 31 corresponding to the heated portion of the wearer's face, and in that state the wearer's face Wear on the face.

  Thus, when the mask main body 3 has a multilayer structure, the blocking effect for blocking causative substances such as allergic rhinitis and hay fever, the warming effect on the face and the heating effect are further improved. Further, since the heat generating sheet 5 is between the outer mask portion 30 and the inner mask portion 31, there is no sense of incongruity that the heat generating sheet 5 directly contacts the face. In addition, since the heat generating sheet 5 is inserted into the internal space between the outer mask portion 30 and the inner mask portion 31, it can also be arranged at an arbitrary position within the inner space.

  FIG. 11 illustrates a third embodiment of the present invention. This three-dimensional mask has a multilayer structure of an outer mask portion 30 and an inner mask portion 31 as in the second embodiment. The heat generating sheet 5 is detachably attached to the inside of the outer mask portion 30 in the three-dimensional mask (A) and the outer portion of the inner mask portion 31 in the three-dimensional mask (B) via the adhesive portion 25. .

  Thus, even when the mask body 3 has a multilayer structure and the heat generating sheet 5 is interposed between the layers, the heat generating sheet 5 can be adhered to the outer mask part 30 or the inner mask part 31 via the adhesive part 25. Good. In the case of (B), since the heat generating sheet 5 is attached to the outside of the inner mask portion 31, the heat generating sheet 5 can be attached with the inner mask portion 31 closed in a flat shape, and the heat generating sheet 5 can be easily attached. Can be attached.

  12-14 illustrate a fourth embodiment of the present invention. In this three-dimensional mask, the shape retaining body 33 is provided on the left and right nonwoven fabric sheets 1 of the mask body 3, and the heat generating sheet 5 is attached to the inner surface side of the nonwoven fabric sheet 1 via the adhesive portion 25 corresponding to the shape retaining body 33. ing.

  The shape retaining body 33 is for making the upper side of the nonwoven fabric sheet 1 conform to the uneven shape of the face, and is formed in a thin strip shape or the like. Between the upper end side and the upper end side of the joint part 20 of the main cover part 6, it is provided substantially symmetrically in the oblique direction along the upper end edge.

  The shape-retaining body 33 is, for example, a tape-like material made of a polyolefin-based synthetic resin whose molecular arrangement is arranged in a uniaxial direction, or one provided with a plurality of metal wires. The shape retaining body 33 may be provided on the inner surface side of the mask main body 3. The shape retaining body 33 is covered with a cover 34 such as a nonwoven fabric. Further, the shape retaining body 33 may be integrated with portions corresponding to the respective nonwoven fabric sheets 1.

  The heat generating sheet 5 is provided with adhesive portions 25 at a plurality of locations of the upper portion and the lower portion, and the upper adhesive portion 25 is a non-woven fabric at a position corresponding to the shape retaining body 33 and the lower adhesive portion 25 is removed from the shape retaining body 33. The sheet 1 is detachably attached to the inside of the sheet 1. In addition, you may provide the adhesion part 25 in the substantially whole surface of the back surface side.

  In this way, by pressing the shape-retaining body 33 from the front side to the face side after mounting, the shape-retaining body 33 is bent along the concavo-convex shape on both sides of the nasal bridge portion as shown in FIG. Further, the fitting property on the upper side of the mask body 3 is further improved.

  Moreover, by sticking the adhesive part 25 to the nonwoven fabric sheet 1 corresponding to the shape-retaining body 33, the heat generating sheet 5 can be easily attached via the adhesive part 25, and the rigidity of the heat generating sheet 5 is non-woven fabric sheet 1. Even if it is larger than that, the heat retaining sheet 5 can be reliably supported by the shape retaining member 33 along the uneven shape of the face. Therefore, even when the heat generating sheet 5 is pasted with the mask body 3 closed, and then the nonwoven sheet 1 of the mask body 3 is spread left and right, the nonwoven sheet 1 is not wrinkled.

  Moreover, when the mask main body 3 is expanded, each nonwoven fabric sheet 1 becomes circular arc shape also in the vertical direction. For this reason, after the mask main body 3 is expanded and formed into a three-dimensional shape, if the lower adhesive portion 25 is pressed against the nonwoven fabric sheet 1 and adhered, not only the lower side of the heat generating sheet 5 can be fixed, but also between the upper and lower adhesive portions 25. Generation | occurrence | production of the wrinkle etc. of the nonwoven fabric sheet 1 can be prevented.

  15 and 16 illustrate a fifth embodiment of the present invention. In this three-dimensional mask, adhesive portions 25 are provided on the left and right sides of the heat generating sheet 5, and the heat generating sheet 5 is detachably attached to the inside of the nonwoven fabric sheet 1 through the adhesive portions 25. For example, on the side near the joining edge 2 of the heat generating sheet 5, the adhesive portion 25 is provided on the end edge side in a wide range in the vertical direction.

  In this case, after the left and right nonwoven fabric sheets 1 are spread, for example, as shown by a two-dot chain line in FIG. 16, the adhesive portion 25 on the side close to the joining edge 2 is adhered to the nonwoven fabric sheet 1 in the vicinity thereof. Then, after spreading the mask body 3 into a predetermined three-dimensional shape, the adhesive part 25 on the far side is pressed against the nonwoven fabric sheet 1 and attached. In this way, even when the heat generating sheet 5 is long in the left-right direction, wrinkles of the nonwoven fabric sheet 1 between the left and right adhesive portions 25 can be prevented.

  17 to 22 illustrate a sixth embodiment of the present invention. In this three-dimensional mask, as shown in FIGS. 17 to 20, the joining edge 2 on the upper side from the top of the nose portion 12 is formed in a substantially straight shape, and the heating portions 5 a corresponding to the left and right nonwoven fabric sheets 1 are integrally provided. An integrated heat generating sheet 5 is detachably attached to the inner side of the nonwoven fabric sheet 1 corresponding to the straight portion 2b. The mask main body 3 has a shape retaining body 33, and the heat generating sheet 5 may be attached corresponding to the shape retaining body 33. The heating sheet 5 may have a length for heating the left and right maxillary sinuses 9 as long as it has a length straddling the left and right nonwoven fabric sheets 1.

  As shown in FIG. 21, the heat generating sheet 5 has a front sheet 22 and a back sheet 23 which are long in the left-right direction, and exothermic powder 24 is filled between both sheets 22 and 23 on both sides except for the middle part thereof. The heat generating part 5a is provided, and the back surface of the back sheet 23 is provided with an adhesive part 25 and a release paper 26 for protecting the adhesive part 25 over the entire surface. The heat generating sheet 5 has a structure having heat generating portions 5a on both the left and right sides, and a connecting portion 5b for connecting the heat generating portions 5a at the approximate center in the left and right direction. Of course, the heat generating sheet 5 before use is sealed with a sealing bag 27 as shown in FIG.

  When using this three-dimensional mask, after expanding the mask body 3 to form a three-dimensional shape, the connecting portion 5b between the heat generating portions 5a is on the bonding edge 2, and the heat generating portions 5a on both sides are on the nonwoven fabric sheet 1 on both sides of the bonding edge 2. The heat generating sheet 5 is stuck inside the left and right nonwoven fabric sheets 1 via the adhesive portions 25 so as to correspond to each.

  Thus, if the heat generating sheet 5 having the two heat generating portions 5a corresponding to each nonwoven fabric sheet 1 is used, it is more convenient than the case where the heat generating sheets 5 are individually attached to the left and right nonwoven fabric sheets 1. Further, although the heat generating sheet 5 has a predetermined width in the vertical direction, since the non-woven sheet 1 is spread left and right so that the mask body 3 has a three-dimensional shape because it adheres to the back side corresponding to the straight portion 2b of the joining edge 2. Even in this case, the heat generating sheet 5 is not curved in the vertical direction along the joining edge 2. Therefore, when the mask main body 3 is made three-dimensional, its shape is not damaged by the heat generating sheet 5.

  23 to 26 illustrate a seventh embodiment of the present invention. As shown in FIGS. 23 and 24, the heat generating sheet 5 of this embodiment is provided with adhesive portions 25 on both sides except for the connecting portions 5 b between the heat generating portions 5 a corresponding to the nonwoven fabric sheets 1. Therefore, there is no adhesive portion 25 on the back side of the connecting portion 5b.

  If it does in this way, while sticking with respect to the nonwoven fabric sheet 1 of the heat generating sheet 5 is easy, the mask main body 3 can be easily extended to a solid shape after that. When sticking the heat generating sheet 5, the heat generating sheet 5 is folded in two with the adhesive portion 25 on the outside, and the connection portion 5b without the adhesive portion 25 has a slack 5c as shown in FIG. It inserts between a pair of V-shaped nonwoven fabric sheets 1. And if the front-end | tip of the fold-like heat generating sheet 5 hits between a pair of V-shaped nonwoven fabric sheets 1, a pair of nonwoven fabric sheets 1 will be pressurized from both sides, and the adhesion part 25 will be stuck on each nonwoven fabric sheet 1. FIG.

  Thereafter, when both the nonwoven fabric sheets 1 are spread to the left and right, there is a slack 5c portion on the connecting portion 5b side of the heat generating sheet 5, so that the heat generating sheet 5 is obstructed despite being pasted on both the nonwoven fabric sheets 1 first. The mask body 3 can be expanded into a three-dimensional shape without becoming.

  The slack 5c of the connecting portion 5b of the heat generating sheet 5 may be provided at the time of sticking. However, as shown in FIG. 26, in the manufacturing process of the heat generating sheet 5, the front sheet 22 and the back sheet 23 are heat welded. When doing, you may shape | mold previously by thermoforming etc.

  27 to 31 illustrate an eighth embodiment of the present invention. As shown in FIGS. 27 to 29, the heat generating sheet 5 of this embodiment has a notch 35 corresponding to the bonding edge 2 of the mask body 3 at the approximate center in the left-right direction. The notch 35 is formed in a U shape from both the upper and lower sides, leaving the connecting portion 5b in the middle. The adhesive portion 25 is provided on the back surface of the heat generating sheet 5, but it may be provided on the substantially entire surface, or may be provided in a streak shape or a dot shape by being distributed substantially uniformly over the entire surface. The heat generating sheet 5 is normally enclosed in a sealing bag 27.

  When these heat generating sheets 5 are used, after the heat generating sheet 5 is taken out from the sealing bag 27, the notch portion 35 is interposed via the adhesive portion 25 so as to correspond to the inside of the joining edge 2 of the mask body 3. It sticks inside the nonwoven fabric sheet 1. At that time, for example, as shown in FIG. 30, the heat generating sheet 5 is folded in two, and the connection part 5 b is applied to the inside of the joining edges 2 of the left and right nonwoven fabric sheets 1 of the mask body 3 to join the connection part 5 b. Push to the edge 2 side.

  In this manner, the entire heat generating sheet 5 is deformed along the three-dimensional shape of the mask body 3 while the left and right widths of the upper and lower cutout portions 35 are narrowed as indicated by the two-dot chain line in FIG. Therefore, the heat generating sheet 5 can be easily deformed along the three-dimensional shape of the mask body 3 even though the sheet-shaped heat generating sheet 5 is attached to the mask main body 3 that becomes a three-dimensional shape when spread. In other words, wrinkles or the like do not occur in either the mask body 3 or the heat generating sheet 5. For this reason, it is not necessary to comprise the joining edge 2 of the sticking site | part of the heat generating sheet 5 in linear form.

  The cutout portion 35 may be formed in a V shape on the lower side, leaving the upper connection portion 5b as shown in FIG. 31A, or the lower connection portion as shown in FIG. You may form in slit shape from the upper side, leaving 5b. Further, as shown in (C), the cutout portion 35 may be formed in an opening shape such as a long hole in the middle while leaving the upper and lower connecting portions 5b.

  The adhesive portion 25 is provided on substantially the entire back surface including the connecting portion 5b as shown in (A), and is provided at a plurality of locations such as near both sides of the connecting portion 5b and the notch portion 35 as shown in (B). Alternatively, only the connecting portion 5b may be provided as shown in (C).

  In addition, if the adhesive part 25 is provided at intervals in the up-down direction and the left-right direction as shown in (B), or if the adhesive part 25 is provided at intervals in the up-down direction as shown in (C), When the mask main body 3 is expanded to the left and right to form a three-dimensional shape, the left and right nonwoven fabric sheets 1 are curved into a predetermined shape without the heat generating sheet 5 being in the way even though the heat generating sheet 5 is present on the inner surface side. Can do.

  32 and 33 illustrate a ninth embodiment of the present invention. FIG. 32 shows a disposable three-dimensional mask enclosing body, in which the three-dimensional mask 36 including the integrated heat generating sheet 5 is enclosed in a sealing bag 37 having gas barrier properties. The exothermic sheet 5 is filled with exothermic powder 24 between the non-woven fabric sheet 1 and a non-woven fabric front sheet 22 whose outer periphery is fixed to the non-woven fabric sheet 1 by heat fusion or the like. The three-dimensional mask 36 is enclosed in the sealing bag 37 in a flat state or a state in which the three-dimensional mask 36 is folded in half, and is taken out from the sealing bag 37 when in use.

  Thus, the three-dimensional mask 36 provided with the heat generating sheet 5 may be enclosed in the sealing bag 37. In this case, there is no trouble of sticking the heat generating sheet 5, and the three-dimensional mask 36 with the heat generating sheet 5 can be used simply. Moreover, you may provide using the nonwoven fabric sheet 1 of the mask main body 3. FIG.

  34 and 35 illustrate a tenth embodiment of the present invention. In the disposable three-dimensional mask enclosure of this embodiment, a three-dimensional mask 36 provided with an adhesive heating sheet 5 is enclosed in a sealing bag 37 having gas barrier properties. The heat generating sheet 5 has a heat generating portion 5 a corresponding to each nonwoven fabric sheet 1, and is adhered to each nonwoven fabric sheet 1 of the mask body 3 through an adhesive portion 25 on the back sheet 23 side. The connecting part 5b between the heat generating parts 5a does not have the adhesive part 25, and the heat generating sheet 5 is stuck to each non-woven fabric sheet 1 with a slack 5c in that part.

  As described above, the three-dimensional mask enclosure 38 may be one in which the three-dimensional mask 36 including the sticking-type heat generating sheet 5 is accommodated in the sealing bag 27. In addition, when sticking the heat generating sheet 5 to the mask main body 3 by the adhesive part 25, the adhesive part 25 may be provided on substantially the entire back surface of the heat generating sheet 5, or may be provided in a streak shape, a dotted shape, or the like. Good.

  36 and 37 illustrate an eleventh embodiment of the present invention. As shown in FIG. 36, the heat generating sheet 5 has a broken portion 39 such as a perforation and a half cut formed in the connecting portion 5b between the heat generating portions 5a in the vertical direction. The heat generating sheet 5 is usually enclosed in a sealing bag 27 with a release paper 26 attached to the adhesive portion 25. The adhesive part 25 may be substantially the entire surface or a part thereof. Further, the heat generating sheet 5 has a shape that is bent in a square shape on both sides of the breaking portion 39 in accordance with the shape of the upper center portion of the mask body 3.

  The heat generating sheet 5 having such a configuration can be used as follows. For example, as shown in FIG. 37, after pasting the non-woven fabric sheet 1 in the shape of a V-shaped left and right nonwoven fabric sheet 1 through the adhesive portion 25 and then pulling both nonwoven fabric sheets 1 left and right, In the process in which the mask main body 3 becomes three-dimensional, a breaking force is applied to the breaking portion 39, and both the upper and lower sides or one side of the breaking portion 39 breaks to the left and right. For this reason, the heat generating sheet 5 can be stuck according to the three-dimensional shape of the mask body 3.

  Also, from the state of FIG. 37, when the connecting portion 5b is pressed and pushed into the joining edge 2 side, the breaking portion 39 breaks at that time, so the heat generating sheet 5 is stuck to the three-dimensional shape of the mask body 3 it can. Furthermore, it may break at the break portion 39 and may be attached separately for each heat generating portion 5a.

  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, in the embodiment, the mask body 3 is illustrated as having the protruding cover 7 that covers the upper surface of the ethmoid sinus 16 on the upper side of the main cover 6, but the mask main body 3 may not have the protruding cover 7. .

  In addition to heating the surface portion of the ethmoid sinus 16, the heat generating sheet 5 may be configured to have a size for heating the surfaces of the nasal cavity 8 and the maxillary sinus 9, for example, a belt shape long in the left-right direction. Therefore, the outer shape of the heat generating sheet 5 is not particularly a problem.

  Although it is desirable that the heat generating sheet 5 does not contact the wearer's face when the three-dimensional mask is worn, the heat generating sheet 5 may be contacted. In the case of the sticking type heat generating sheet 5, the adhesive portion 25 on the back surface side thereof may be provided on the substantially front surface, or may be provided in an approximately uniformly distributed manner in the form of streaks or dots. Furthermore, it may be partially provided only in the connection portion 5b or in substantially the entire region other than the connection portion 5b. In addition, the fracture | rupture part 39 may be provided in the up-and-down both sides of the connection part 5b, and may be formed in V shape, U shape, and other shapes.
