Description

  The present invention relates to a three-dimensional mask that includes a mask body formed so as to protrude to the front side and covers a nostril and lips of a wearer.

  Conventionally, masks are roughly classified according to their shapes into a flat mask and a three-dimensional mask.

  In general flat masks, an appropriate size gauze is folded over as many times as necessary, and then the outer periphery of the gauze is sewn, and appropriate ear straps are attached to the left and right sides of the gauze. Is formed.

  However, in such a flat mask, there is a problem that the gauze positioned on the wearer side, that is, the inner side, comes into contact with the nostril and lips of the wearer, and there is a risk that lipstick may be attached or breathlessness may be felt. .

  On the other hand, since a space is formed between the lip of the wearer and the inner surface of the nostril when the three-dimensional mask is worn, the lip or nostril of the wearer contacts the inner surface of the mask. There is no lipstick attached, and there is no feeling of breathlessness.

  As a result, in general, it can be said that the three-dimensional mask has a better wearing feeling than the flat mask.

  Even in a three-dimensional mask, there are a case of a flat plate type before wearing and a case of a three-dimensional type already before wearing.

  Before wearing, for example, as shown in FIG. 7, the flat plate type includes a mask body 1 formed in a quadrangular shape by, for example, a non-woven fabric, and the mask body 1 is folded at a plurality of locations so that a plurality of folds 2 are left and right. It forms along both sides, and both sides are fixed, and the strings 3 and 3 for ear hanging are joined to these both sides.

  When the mask main body 1 is worn, as shown in FIG. 8, the folding pieces spread vertically from the folds 2 folded by extending the upper and lower end portions of the mask main body 1, and the wearer 5 A three-dimensional mask having a convex shape is formed on the opposite side.

  However, in the three-dimensional mask shown in FIGS. 7 and 8, a space is obtained in the vicinity of the nostril 5a and lips 5b of the wearer 5 and adhesion to the nose can be obtained, but the shape of the mask body 1 is It is not stable and it is not easy to maintain adhesion for a long time.

  On the other hand, since the three-dimensional type can be maintained relatively firmly before wearing, it is difficult to lose its shape and can be used for a relatively long time.

As such a three-dimensional mask, a flexible nonwoven fabric mainly made of appropriate synthetic resin fibers having air permeability between a front side member and a back side member formed of a breathable material such as gauze. There is known a configuration in which a core material is disposed as a convex member that is formed by pressure molding into a predetermined substantially spherical shape. In this three-dimensional mask, since the non-woven fabric competed by pressure molding maintains a substantially spherical shape with a certain degree of strength, it has a three-dimensional shape before wearing (for example, refer to Patent Document 1).
JP 2001-37894 A (page 2-3, FIG. 2-10)

  However, in the above-described three-dimensional mask, since a space is formed between the wearer's lips or nostrils and the inner surface, the mask body does not come into contact with the lips or nostrils. Although it can solve problems such as attachment of breath and breathlessness, the mask body is not sufficiently close to the nose, preventing pollen from entering the nose, or wearing by the wearer In this case, there is a problem that the effect of preventing fogging of the glasses is not sufficient.

  Further, in the above-described three-dimensional mask, a configuration is also described in which, when the core material is molded, irregularities that are in close contact with the raised shape of the nose are formed in portions that contact both sides of the nose of the wearer of the core material. Since such uneven shapes vary depending on the wearer, depending on the wearer, it is not easy to ensure sufficient adhesion near the nose. Alternatively, the effect of preventing fogging of the glasses when the wearer wears glasses is not sufficient.

  The present invention has been made in view of these points, and an object of the present invention is to provide a three-dimensional mask that ensures adhesion between the wearer's nose and the mask body.

  The three-dimensional mask according to claim 1 includes a front side member formed of a breathable material, a back side member formed of the breathable material, and a protrusion sandwiched between the front side member and the back side member. A square-shaped mask body that includes a mold member and is formed so as to protrude to the front surface side, and an ear hook portion that is provided on both sides in the lateral direction of the mask body and is engaged with a wearer's ear, The mask main body extends from the upper end in the vertical direction and is folded downward through the first fold, and extends from the tip of the first fold and extends through the second fold. A second folded piece that is folded upward with respect to the first folded piece, and the first folded piece and the second folded piece are sequentially positioned on the wearer side with respect to the mask body. 1 folding piece and the first In which lateral sides of the mask body are joined in a state where the folding piece is folded.

  Then, by forming a mask body so that the mask body protrudes to the front side by sandwiching a convex member between the front side member and the back side member respectively formed of the breathable material, the three-dimensional mold of the mask body While preventing collapse, at the time of wearing, the first and second fold pieces, which are folded at the upper end in the vertical direction of the mask body and joined on both sides in the horizontal direction, are separated from the first fold portion and the second fold portion. By expanding each of them and bringing them into close contact with the wearer's nose, the adhesion between the wearer's nose and the mask body is ensured.

  The three-dimensional mask according to claim 2 is the three-dimensional mask according to claim 1, wherein the dimension obtained by adding the vertical dimension of each of the first folded piece and the second folded piece is the first folded piece and the first folded piece. 2 It is 40% to 50% of the vertical dimension of the mask body in the folded state.

  And the dimension which added each vertical direction dimension of the 1st folding piece and the 2nd folding piece is made into 40%-50% of the vertical dimension of the mask body in the state where these each folding piece was folded. In addition to ensuring that the upper end of the mask body reaches the nose of the wearer, the upper end of the mask body is prevented from becoming excessive at the base of the nose. improves.

  A three-dimensional mask according to a third aspect is the three-dimensional mask according to the first or second aspect, wherein the convex member is formed by press-molding a nonwoven fabric.

  Then, by forming the convex member by pressure forming the nonwoven fabric, the convex member can be easily manufactured, and the productivity is improved.

  A three-dimensional mask according to a fourth aspect is the three-dimensional mask according to the first or second aspect, wherein the convex member is formed by three-dimensionally molding paper having air permeability.

  And manufacturing cost is suppressed by solid-molding the paper which has air permeability, and forming a convex-shaped member.

  A three-dimensional mask according to a fifth aspect of the present invention is the three-dimensional mask according to any one of the first to fourth aspects, wherein the convex member is detachable from the mask body.

  By making the convex member detachable from the mask main body, for example, the mask main body and the convex member can be separately washed when not worn, and the usability is improved.

  According to the first aspect of the present invention, the mask body is formed so as to protrude to the front surface side by sandwiching the convex member between the front surface side member and the back surface side member formed by the breathable material. The three-dimensional shape of the mask main body can be prevented from being deformed, and when worn, the first fold piece and the second fold piece, which are folded at the longitudinal upper end of the mask body and joined on both sides in the lateral direction, The contact between the wearer's nose and the mask main body can be ensured by expanding each of the portion and the second fold portion and closely contacting the wearer's nose.

  According to the second aspect of the present invention, the dimension obtained by adding the vertical dimension of each of the first folded piece and the second folded piece is 40, which is the vertical dimension of the mask body in a state in which each folded piece is folded. By making it 50% to 50%, the vertical upper end of the mask body can be surely delivered to the wearer's nose, and the vertical upper end of the mask body is prevented from becoming excessive at the nose. The adhesion to the nose can be further improved.

  According to invention of Claim 3, a convex member can be easily manufactured by press-molding a nonwoven fabric and a convex member is formed, and productivity can be improved.

  According to invention of Claim 4, manufacturing cost can be suppressed by solid-molding the paper which has air permeability, and forming a convex-shaped member.

  According to the invention of claim 5, by making the convex member detachable from the mask main body, for example, the mask main body and the convex member can be separately washed when not worn, which is convenient. It can be improved.

  The configuration of an embodiment of the present invention will be described below with reference to FIGS.

  1 to 6, reference numeral 11 denotes a three-dimensional mask. The three-dimensional mask 11 is bonded to a horizontally long rectangular mask body 12 having both sides in the horizontal direction and both ends in the vertical direction, and both sides of the mask body 12. And an ear hook string 13 as an ear hook section.

  As shown in FIG. 6, the mask main body 12 has a front surface side member 15 and a back surface side member 16 formed in a horizontally long rectangular shape, and a convex shape is formed between the front surface side member 15 and the back surface side member 16. By sandwiching the member 17, the mask main body 12 is formed into a three-dimensional shape protruding to the front side, and has become a three-dimensional shape before wearing.

  Further, the mask body 12 has a first folding piece 22 extending from the upper end portion via the first fold portion 21 by the front surface side member 15 and the back surface side member 16, and the tip of the first folding piece 22. A second fold piece 24 is extended from the portion through a second fold portion 23, and the first fold piece 22 and the second fold piece 24 are located inside the mask body 12, that is, on the wearer 25 side shown in FIG. The both sides in the lateral direction are joined in a state in which the folded pieces 22 and 24 are folded so as to be sequentially positioned. In this state, the mask body 12 is formed to have a horizontal dimension of 12 to 18 cm and a vertical dimension of about 7 to 10 cm, for example.

  As shown in FIGS. 1 to 5, the front surface side member 15 and the back surface side member 16 are formed in a horizontally long rectangular shape with a breathable material such as cotton, non-woven fabric, or nylon, and are mounted integrally on both sides. The side joints 27 and 27 are formed by being folded back and joined to the wearer 25 side, and the lower joint part 28 is formed by being folded and joined to the wearer 25 side integrally at the lower end. Has been. The joint portions 27 and 28 are joined by, for example, sewing, welding, or adhesion.

  Further, as shown in FIGS. 1 to 6, the front surface side member 15 and the back surface side member 16 are provided with support portions 29 for supporting the convex member 17 at positions closer to the lower side. The support portions 29 are formed, for example, in an arc shape along the lower portion of the convex member 17, and are located on both sides of the lower portion of the convex member 17 sandwiched between the front surface side member 15 and the back surface side member 16. The support portion 29 is a seam formed by sewing in the present embodiment, but may be formed by a joining method such as adhesion or heat sealing.

  In addition, the convex member 17 is formed by press molding after heat softening in a convex cup-shaped mold frame by stacking a plurality of breathable nonwoven fabrics mainly made of synthetic resin fibers such as polypropylene. It is formed in a cup shape, and is supported at the center in the horizontal and vertical directions of the mask body 12. Therefore, when the three-dimensional mask 11 is worn, a space is formed between the nostrils 25a and lips 25b of the wearer 25 and the back surface side member 16 on the wearer 25 side of the mask body 12. The convex member 17 is preferably detachable from the mask body 12.

  Further, as shown in FIGS. 2 and 6, the first folding piece 22 is a portion that substantially coincides with the upper end portion of the convex member 17 via the first fold portion 21 formed at the upper end portion of the mask body 12. 1 is folded to the wearer 25 side shown in FIG. That is, the first fold portion 21 is a mountain fold. In this state, the lower end portion of the first folding piece 22 is located between the upper end portion and the protruding top portion of the convex member 17 sandwiched between the front surface side member 15 and the back surface side member 16.

  Further, as shown in FIGS. 2, 3 and 6, the second folding piece 24 is connected to the front end portion of the first folding piece 22, that is, through the second fold portion 23 formed at the lower end portion in the folded state. The first folded piece 22 is folded upward. In this state, the upper end portion of the second folding piece 24 is positioned above the first fold portion 21. Further, as shown in FIGS. 1 to 5, an upper joint portion in which the front side member 15 and the back side member 16 are integrally folded and joined to the wearer 25 side at the upper end portion of the second folding piece 24. 31 is formed.

  The folded pieces 22 and 24 are joined at the side joints 27 on both sides of the mask body 12. For this reason, when the three-dimensional mask 11 is worn, by pulling the folded pieces 22, 24 upward from the mask body 12, as shown in FIG. 1 and FIG. Is stretched upward at a predetermined angle with respect to the first fold portion 21 of the mask body 12 to form a widened portion 32.

  As shown in FIG. 6, the vertical dimension L1 of the center part in the horizontal direction of the spread part 32, that is, the dimension including the vertical dimension of each folding piece 22, 24 is the folded state of each folding piece 22,24. That is, it is formed to be 40% to 50% with respect to the longitudinal dimension L2 of the mask body 12 before wearing. Accordingly, if the longitudinal dimension L1 of the spread portion 32 is 40% with respect to the longitudinal dimension of the average mask body 12 of approximately 9.5 cm, the longitudinal dimension L1 is approximately 3.8 cm. , 24 when the mask body 12 is expanded, the longitudinal dimension L3 of the mask body 12 substantially matches the ergonomic average size from the human eye to the chin, which is 12 cm.

  Further, as shown in FIG. 1, each of the ear straps 13 is respectively engaged with a pair of ears 25c (only one is shown) of the wearer 25. Arbitrary things, such as string-like objects, such as a rubber string, or belt-like objects, such as a nonwoven fabric, can be selected.

  Next, the operation of the above embodiment will be described.

  When the three-dimensional mask 11 is worn, the wearer 25 engages the ear straps 13 with the ears 25c, and the mask body 12 is positioned near the front side of the lips 25b. The upper end portion is pulled up toward the nose, and the first folded piece 22 and the second folded piece 24 are extended to form a widened portion 32.

  At this time, since both end portions in the lateral direction of the folding pieces 22 and 24 are joined by the side joint portions 27, as shown in FIG. 1 and is formed so that the amount of extension gradually decreases from the central portion to both sides, so that the wearer 25 has a widened portion as shown in FIG. Make sure that the center of 32 is in close contact with the nose.

  In this state, the convex member 17 maintains the solid shape in which the central part of the mask body 12 protrudes to the surface side relatively firmly, prevents the shape from being lost, and can be worn with confidence for a relatively long time. Since the inner surface of the mask body 12, that is, the back surface side member 16, does not contact the 25 nostrils 25a and the lips 25b, the lipstick adheres to the mask body 12 when the wearer 25 feels short of breath or when a woman wears it. There is nothing to do.

  In addition, since the three-dimensional shape is maintained by the convex member 17 in this way, when the widened portion 32 is formed at the time of wearing, the angle of the widened portion 32 extending above the mask body 12 is the nose of the wearer 25 Since it almost coincides with the angle, the spread part 32 naturally touches the nose of the wearer 25, and the nose of the wearer 25 is compared with the case where the fold part of the conventional flat mask is spread and closely adhered to the face. Adhesion with the mask body 12 is good, for example, the effect of preventing invasion of pollen and the like is improved, and when the wearer 25 wears spectacles, the spectacles also have an anti-fogging effect. A mold mask 11 can be worn.

  Further, the vertical dimension L1 of the central part in the horizontal direction of the spread part 32 is set to 40% to 50% of the vertical dimension L2 of the mask body 12 in a state where the folding pieces 22 and 24 are folded, for example, vertical. As in the case where the directional dimension L1 is less than 40%, the upper end in the vertical direction of the mask body 12 does not reach the nose of the wearer 25 and the adhesion is deteriorated, so that the sense of security when wearing the three-dimensional mask 11 is reduced. Or when the vertical dimension L1 is larger than 50%, the widened portion 32 is excessive at the base of the nose, and the upper end of the lateral center becomes a fold at the base of the nose, resulting in poor adhesion. Thus, it is possible to prevent a sense of incongruity from occurring when the three-dimensional mask 11 is worn, and to further improve the adhesion to the nose and the feeling of wearing.

  That is, unlike a conventional three-dimensional mask that can only cover the tip of the nose, the entire nostril is covered with the widened portion 32 by providing the folding pieces 22 and 24, and the nose of the wearer 25 and the mask body 12 Can be secured.

  Further, although the unevenness of the raised shape of the nose of the wearer 25 varies depending on the individual, the wearer 25 can form the widened portion 32 by appropriately extending the folding pieces 22 and 24 as in the above embodiment. Since the spreading portion 32 can be formed according to the shape of its own nose, the adhesion between the mask body 12 and the base of the nose can be secured without selecting the wearer 25.

  Furthermore, compared to the conventional case in which the shape of the convex member 17 is previously formed according to the raised shape of the nose of the wearer 25, it is not necessary to finely process the convex member 17 itself, so that the three-dimensional mask 11 The productivity of can be improved.

  Further, by making the convex member 17 removable from the mask main body 12, for example, the mask main body 12 and the convex member 17 can be separately washed when the three-dimensional mask 11 is not worn. The mold member 17 can be reused while checking the state of the mold member 17 and the usability of the three-dimensional mask 11 can be improved. It can be inserted into the mask body 12 and the wearing feeling of the three-dimensional mask 11 can be further improved.

  Further, by forming the convex member 17 by pressure forming a nonwoven fabric, the convex member 17 can be easily manufactured and productivity can be improved.

  In the above embodiment, the convex member 17 is made of a material that does not lose its shape after being washed once or twice, for example, paper such as Japanese paper having air permeability and a certain degree of strength, and a part thereof. It is also possible to form a cup by three-dimensional molding so as to form a cone by cutting and overlapping a part thereof and bonding them. For example, when the convex member 17 is three-dimensionally formed from paper, the manufacturing cost of the convex member 17 can be suppressed.

  In addition, a metal strip is encapsulated in the upper joint portion 31, or the lateral center portion of the upper joint portion 31 is sewn and sewn, so that the wearer's 25 nose 32 adheres to the nose. It is also possible to improve.

  Furthermore, in addition to the above-described embodiments, it is also possible to carry out with appropriate modifications within a range that can be adapted to the above-mentioned purpose.
