Description

  The present invention relates to a mask.

  As a conventional mask, there has been known a mask in which a mask body part covering a mouth part and a nose part is subjected to a lateral pleating process (a lateral pleating process) (for example, see Patent Document 1). In the mask described in Patent Document 1, lateral pleat processing is applied to a substantially rectangular mask main body, and V-shaped cuts that are stress relief portions are formed at the center of both left and right ends of the mask main body. Yes. At the time of wearing, the pleats spread in the vertical direction to create a three-dimensional effect on the mask and improve the wearability, and the stress relief part absorbs the bending stress generated on the side of the mask body, so the mask and the face The adhesiveness of is improved.

JP 2008-55035 A

  However, in the mask described in Patent Document 1 as described above, even if the stress generated on the side portion of the mask body can be released, the generation of stress itself cannot be weakened. For this reason, for example, when stress cannot be sufficiently absorbed in the stress relief portion, the adhesion between the mask side portion and the face may be reduced.

  The present invention has been made to solve such a technical problem, and an object of the present invention is to provide a mask that can improve the adhesion between the side of the mask main body and the face when worn. .

  That is, the mask according to the present invention comprises a mask body portion that has been subjected to pleating in the lateral direction, and a linear or belt-like ear hooking member that is attached to each of both ends in the lateral direction of the mask body portion, One end portion and the other end portion of the ear hooking member are configured to be attached at a predetermined interval such that a tensile force by the ear hooking member acts on the outer side in the vertical direction of the mask main body at the time of wearing.

  In the mask according to the present invention, the one end and the other end of the ear hooking member are attached at predetermined intervals so that the tensile force by the ear hooking member when worn is applied to the outside in the vertical direction of the mask main body. Thus, the attachment position of the one end part and the attachment position of the other end part of the ear hooking member are adjusted, and the tensile force by the ear hooking member at the time of wearing acts on the outer side in the vertical direction of the mask main body part. For this reason, it is possible to prevent the tensile force from acting on the inner side in the vertical direction of the mask main body at the time of mounting, so that it is possible to suppress the bending at the end in the horizontal direction of the mask main body. Therefore, the adhesion between the side portion of the mask main body portion and the face can be enhanced at the time of wearing.

  Here, the one end portion and the other end portion of the ear hook member are attached from the upper ear hook portion from the upper root of the wearer's ear to the one end portion of the ear hook member and the lower root of the wearer's ear at the time of wearing. It is preferable that the ear hooking member is attached at the predetermined interval such that the distance from the lower ear hooking portion to the other end portion of the ear hooking member becomes smaller as it approaches the mask main body portion.

  By configuring in this way, it is possible to avoid the tensile force due to the upper ear hook portion acting downward on the mask main body portion, while the tensile force due to the lower ear hook portion acts upward on the mask main body portion. Can be avoided.

  Further, the mask according to the present invention comprises a mask body portion that has been subjected to pleating in the lateral direction, and a linear or belt-like ear hooking member that is attached to each of both ends in the lateral direction of the mask body portion, One end portion and the other end portion of the ear hooking member are attached at a predetermined interval shorter than between both longitudinal end portions of the mask main body portion.

  In the mask according to the present invention, the one end and the other end of the ear hooking member are attached at a predetermined interval shorter than the distance between both ends in the longitudinal direction of the mask main body. Thus, by adjusting the attachment position of the one end portion of the ear hook member and the attachment position of the other end portion of the ear hook member, the component acting on the inside in the vertical direction of the tensile force by the ear hook member at the time of wearing is adjusted. Can be suppressed. For this reason, it becomes possible to suppress a bending in the edge part of the horizontal direction of a mask main-body part. Therefore, the adhesion between the side portion of the mask main body portion and the face can be enhanced at the time of wearing.

  Here, the predetermined interval may be the same as the length between the upper and lower roots of the wearer's ear or may be shorter than the length between the upper and lower roots of the wearer's ear. The predetermined interval may be 5 cm or less. In addition, the length between the upper and lower roots of the ear in a general adult male is about 6 cm, and it is 5.5 cm in a general adult female.

  Further, the mask main body may be a hexagonal sheet member obtained by obliquely cutting a rectangular corner. When the distance between the mounting position of one end of the ear hooking member and the mounting position of the other end is shortened, the influence of the tensile force of the ear hooking member on the corner area of the mask main body is reduced, but the rectangular corner By using a hexagonal sheet member that is cut off obliquely, unnecessary corner areas of the mask body can be eliminated. For this reason, it is possible to enhance the wearing feeling.

  Moreover, it is preferable that the mask main body is a sheet member obtained by obliquely cutting a rectangular corner. By comprising in this way, since the curve part of the outer periphery of a mask main-body part closely_contact | adheres along a face at the time of mounting | wearing, a mounting feeling can be improved further.

    ADVANTAGE OF THE INVENTION According to this invention, the adhesiveness of the side part of a mask main-body part and a face can be improved at the time of mounting | wearing.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted. Unless otherwise specified, the vertical direction indicates the direction in the explanatory drawing.

(First embodiment)
The mask according to the first embodiment is an ear-hook type mask that is pleated in the lateral direction, and is suitably employed as, for example, a sanitary mask, a pollen mask, a dust mask, or a medical mask. FIG. 1 is a top view showing a folded state of the mask according to the present embodiment.

  As shown in FIG. 1, the mask 1 includes a mask main body 2 that covers the mouth and nose of the wearer. The mask main body 2 is a substantially rectangular sheet member, and has a size that can sufficiently cover the mouth and the nose. For this reason, the length between both ends 2b, 2c in the vertical direction (vertical direction) of the mask main body 2 is made longer than the root width of the wearer's ear. Usually, the length between both ends 2b and 2c is 9 cm to 9.5 cm. The base material which comprises the mask main-body part 2 is formed, for example with a nonwoven fabric, and has the function to interrupt | block dust, various germs, pollen, etc. while having air permeability.

  The mask main body 2 is folded into a pleat shape in consideration of improvement in wearability, elimination of breathing difficulty at the time of wearing, ease of conversation, and the like. The pleat 4 is a lateral pleat provided along the longitudinal direction (lateral direction), and is folded so that the sheets overlap in the longitudinal direction of the mask body 2. The pleat 4 is formed so as to extend to both end portions 2a, 2a (both edges) in the lateral direction of the mask main body 2. In addition, the mask body 2 is fixed by thermal welding or ultrasonic welding of the peripheral edges in a broken line shape, and a nose fit 20 as a flexible member is inserted and held in one end 2b in the vertical direction. .

  At both ends 2a, 2a in the lateral direction of the mask main body 2 are attached ear hook members 3 for passing over the wearer's ears. The ear hooking member 3 is a linear (string-like) elastic member, and both end portions 3 a and 3 b are attached to both end portions 2 a of the mask main body 2 by welding or sewing. As the ear hooking member 3, for example, rubber or elastic fiber material is used. The shape of the ear hooking member 3 may be a band shape.

  The mounting positions A1 and A2 of the both end portions 3a and 3b of the ear hook member 3 are closer to the center side (vertically inward) than the positions A3 and A4 (A5 and A6) of the upper and lower corners of the mask main body 2. That is, the distance L1 between the both end portions 3a and 3b of the ear hooking member 3 is set shorter than between the both end portions 2b and 2c in the vertical direction of the mask main body 2. The interval L1 is, for example, the same as the length between the upper and lower roots of the wearer's ear or shorter than the length between the upper and lower roots of the wearer's ear. Specifically, it is 5 cm or less, preferably 3.5 cm or less.

  FIG. 2 is a schematic diagram illustrating the mask of FIG. 1 at the time of wearing. As shown in FIG. 2, the ear hooking members 3 and 3 are stretched over the wearer's ear 30, and the mask main body 2 is fixed to the face. The shape of the nose fit 20 is adjusted, and the end 2b of the mask main body 2 is in close contact with the nose without a gap. The pleat 4 is spread in the vertical direction to completely cover the mouth and nose, and the mask body 2 swells forward to define a space inside the mask body 2.

  The distance L1 between the one end 3a and the other end 3b of the ear hook member 3 is shorter than the distance L3 (ear root width) between the upper root 30a and the lower root 30b of the wearer's ear 30. For this reason, at the time of wearing, the upper ear hooking portion 3c from the upper root 30a of the wearer's ear 30 to one end 3a of the ear hooking member 3 and the lower portion from the lower root 30b to the other end 3b of the ear hooking member 3 As the distance from the ear hook 3d approaches the mask main body 2, the distance decreases. For example, the distance between the upper ear hooking portion 3c and the lower ear hooking portion 3d gradually decreases from L3 as the distance from the ear 30 toward the mask main body 2 and is set to the distance L2.

  As described above, the upper ear hooking portion 3 c extends upward as viewed from the one end portion 3 a of the ear hooking member 3 and extends over the ear 30, and the lower ear hooking portion 3 d is viewed from the other end portion 3 b of the ear hooking member 3. It extends downward and hangs over the ear 30. For this reason, the tensile force F of the upper ear hooking portion 3 c of the ear hooking member 3 has a component F <b> 1 on the outer side in the vertical direction (upper side) of the mask main body portion 2. Similarly, the tensile force F of the lower ear hooking portion 3d of the ear hooking member 3 has a component F2 to the outside (lower side) in the vertical direction of the mask main body portion 2. For this reason, the edge part 2a of the mask main-body part 2 of the horizontal direction (especially between the one end part 3a and the other end part 3b of the ear hooking member 3) will be in the tensioned state in order to be pulled outside in the vertical direction. As described above, the distance L1 is employed so that the tensile force by the ear hooking member 3 when the mask 1 is worn acts on the outside of the mask main body 2 in the vertical direction. No slack or the like occurs in the portion 2a. That is, the distance L1 between the one end 3a and the other end 3b of the ear hooking member 3 before mounting and the distance L2 between the one end 3a and the other end 3b of the ear hooking member 3 during mounting are substantially the same. .

  By the way, as shown in FIG. 5, the conventional ear-hook type mask subjected to the horizontal pleating process has the attachment positions A 1 and A 2 of the both end portions 3 a and 3 b of the ear hook member 3 at the upper and lower corners of the mask main body 2. It is provided in the vicinity. That is, the distance L4 between the two end portions 3a and 3b of the ear hooking member 3 is substantially the same as the width in the vertical direction of the mask main body 2, that is, the width between the two vertical ends 2b and 2c of the mask main body 2. More specifically, the interval between the attachment positions A1, A2 is 7 cm to 8 cm. When the conventional mask is worn, the upper ear hooking portion 3 c of the ear hooking member 3 extends downward from the one end portion 3 a of the ear hooking member 3 and is passed over the ear 30, and the lower ear hooking portion 3 d is extended to the ear hooking member 3. As viewed from the other end 3 b, it extends upward and spans the ear 30. Then, as shown in FIG. 6, the tensile force F of the upper ear hooking portion 3 c of the ear hooking member 3 has a component F <b> 3 on the inner side (lower side) in the vertical direction of the mask main body portion 2. Similarly, the tensile force F of the lower ear hooking portion 3d of the ear hooking member 3 has a component F4 on the inner side (upper side) of the mask main body portion 2 in the vertical direction. For this reason, at the time of wearing, the upper ear hook 3c and the lower ear hook 3d are substantially parallel to each other, and both lateral ends 2a of the mask main body 2 are bent. That is, the distance L5 between the one end 3a and the other end 3b of the ear hooking member 3 at the time of wearing is shorter than the distance L4 between the one end 3a and the other end 3b of the ear hooking member 3 before wearing. In particular, in a mask that has been subjected to horizontal pleating, since the pleat 4 is spread in the vertical direction, both end portions 2a in the horizontal direction of the mask body 2 are further bent. For this reason, leakage occurs from the mask lateral direction.

  On the other hand, according to the mask 1 according to the first embodiment, the one end 3 a and the other end 3 b of the ear hooking member 3 have a tensile force F generated by the ear hooking member 3 at the time of wearing the mask main body 2. They are attached at a predetermined interval L1 that acts on the outside in the vertical direction. For this reason, it is possible to prevent the tensile force from acting on the inner side in the vertical direction of the mask main body 2 at the time of wearing, so that it is possible to suppress the bending at the lateral ends 2a and 2a of the mask main body 2. It becomes. That is, when the mask 1 that has been subjected to the lateral pleating process is mounted, the tensile force F can be applied in a direction that cancels out the stress on the inner side in the longitudinal direction that acts on both lateral ends 2a of the mask main body 2. Further, it is possible to reduce the longitudinal inward stress (the longitudinal inner component of the tensile force F) applied to the mask main body 2 by the ear hooking member 3 itself. Therefore, the adhesion between the side portion of the mask main body portion 2 and the face can be enhanced at the time of wearing.

  Further, according to the mask 1 according to the first embodiment, the tensile force by the lower ear hooking portion 3d is prevented from acting on the mask main body portion 2 in the downward direction while the tensile force by the upper ear hooking portion 3c is avoided. It is possible to avoid the action of the part 2 in the upward direction.

  Furthermore, according to the mask 1 according to the first embodiment, the one end 3a and the other end 3b of the ear hooking member 3 are at a predetermined interval L1 that is shorter than the distance between the longitudinal ends 2b and 2c of the mask main body 2. It is attached. As described above, the attachment position A1 of the one end 3a and the attachment position A2 of the other end 3b of the ear hook member 3 are adjusted and attached, so that the longitudinal force out of the tensile force F by the ear hook member 3 at the time of wearing is adjusted. Components acting on the inner side in the direction can be suppressed. For this reason, it becomes possible to suppress bending in the edge parts 2a and 2a of the horizontal direction of the mask main-body part 2. FIG. Therefore, the adhesion between the side portion of the mask main body portion and the face can be enhanced at the time of wearing.

(Second Embodiment)
The mask 1 according to the second embodiment is configured in substantially the same manner as the mask 1 according to the first embodiment, and only the shape of the mask main body 2 is different. Therefore, the second embodiment will be described with a focus on differences from the first embodiment, and a duplicate description will be omitted.

  FIG. 3 is a top view showing a folded state of the mask according to the present embodiment. As shown in FIG. 3, the mask 1 according to the present embodiment includes a substantially hexagonal mask main body 2 obtained by obliquely cutting corners of the substantially rectangular mask main body 2 of FIG. 1. Other configurations are the same as those of the first embodiment.

  FIG. 4 is a schematic diagram illustrating the mask of FIG. 3 at the time of wearing. As shown in FIG. 4, the mask 1 according to the second embodiment is similar to the mask 1 according to the first embodiment, because the tensile force of the ear hooking member 3 acts on the outside in the vertical direction of the mask body 2. Looseness does not occur in the lateral end 2a of the main body 2. Further, by shortening the distance between the one end 3a and the other end 3b of the ear hook member 3, in the case of the rectangular mask body 2 as shown in FIG. 1, the upper and lower corners of the rectangular mask body 2 are pressed. Although it is conceivable that the force is weakened and the wearing feeling is lowered, by making the mask main body 2 substantially hexagonal, unnecessary parts can be eliminated and the wearing feeling can be improved.

  As mentioned above, according to the mask 1 which concerns on 2nd Embodiment, while there exists an effect similar to the mask 1 which concerns on 1st Embodiment, the attachment position A1 of the one end part 3a of the ear hook member 3, and the attachment position of the other end part 3b When the distance from A2 is shortened, the effect of the tensile force of the ear hooking member 3 on the corner region of the mask main body 2 is reduced, so that the wearing feeling may be reduced. By using the substantially hexagonal sheet member obtained by obliquely cutting the corners, unnecessary corner regions of the mask main body 2 can be eliminated. For this reason, it is possible to enhance the wearing feeling.

  The embodiment described above shows an example of the mask according to the present invention. The mask according to the present invention is not limited to the mask 1 according to each embodiment, and the mask according to each embodiment can be modified or applied to other ones without changing the gist described in each claim. It may be what you did.

  For example, in the mask 1 according to the second embodiment, the edge portion that becomes the oblique end portion 2d of the mask main body portion 2 is formed linearly, but may be formed curvedly. By being formed in this way, the mask main body 2 can be brought into close contact with a curved face, so that the wearing feeling can be further enhanced.
