  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  In this specification, the side facing the skin when the mask is attached, that is, the side in contact with the nose or mouth is referred to as the inside of the mask, and the side not facing the skin is referred to as the outside of the mask. In addition, the direction coming to the nose side when the mask is attached is called the upper side of the mask, and the direction coming to the chin side is called the lower side of the mask.

  The mask of the embodiment is formed of a sheet in which a plurality of trapezoidal traps are folded, and other than the upper base of the trapezoid (the shorter of the parallel sides) and the lower base (the longer of the parallel sides) And a pair of ear straps attached to the corners of the end points of the bottom of the trapezoid of the main body.

  FIG. 1 is a schematic diagram of a mask according to an embodiment. 1A is a top view as viewed from above, FIG. 1B is a bottom view as viewed from below, and FIG. 1C is a cross-sectional view taken along line AA in FIG. In FIG. 1C, the thickness of the sheet is not shown. FIG. 2 is a development view of the sheet of the main body of the mask according to the embodiment.

  As shown in FIG. 2, the mask 10 according to the embodiment has a main body 20 formed of a sheet in which ten trapezoidal ridges 22 a to 22 j are folded at folds. As shown in FIGS. 1 (a) and 1 (b), the main body 20 includes two joints 24a and 24b located on two sides other than the trapezoidal upper and lower bases, and all the flanges 22a to 22j. Are joined. FIG. 2 is a developed view in which the sheet is unjoined at the joining portions 24a and 24b of the main body 20 and developed.

  The material of the sheet is not particularly limited as long as it has air permeability. Any known material used for the mask is applicable. However, it is desirable to use a non-woven fabric from the viewpoint of ease of processing and economy. Further, the sheet may be a single layer or a laminate of a plurality of types of sheets.

  For joining the ridges at the joining portions 24a and 24b, for example, fusion by heat sealing, adhesion using an adhesive, stitching, or the like is appropriately used.

  Further, as shown in FIGS. 1A and 1B, the mask 10 includes a pair of ear straps 30 attached to the corners of the end points of the lower base of the trapezoid of the main body 20. Yes. That is, the ear straps are attached to the left and right sides of the mask 10, respectively. The ear strap 30 is desirably a stretchable material such as rubber. The ear strap 30 is attached to the main body 20 by a method such as suturing, bonding, or passing through a hole provided in the main body 20.

  Furthermore, it is preferable that a nose clamp 26 extending in the left-right direction of the mask main body 20 is provided in the vicinity of the outer side of the uppermost ridge 22a among the ten ridges. The nose clamp 26 is, for example, metallic. The nose clamp 26 has, for example, a thin line shape, and is used so that the upper side of the mask main body 20 follows the uneven shape of the nose when the mask 10 is mounted. Therefore, the nose clamp 26 is preferably made of a plastically deformable material.

  The nose clamp 26 may be attached to either the outer side or the inner side of the flange 22a. Moreover, as long as the sheet | seat of the main-body part 20 laminated | stacked the some sheet | seat, it may be inserted and attached between sheets.

  FIG. 3 is a top view photograph of an example of the mask according to the embodiment before use. FIG. 4 is a photograph from the outside in which the mask of FIG. FIG. 5 is a photograph from the inside of the mask of FIG.

  As is apparent from FIG. 3, the mask 10 of the embodiment has a rod-shaped and extremely compact shape before use due to a configuration in which all trapezoidal ridges 22a to 22j are joined at two places on the left and right. Therefore, it is excellent in portability. For example, it can be easily carried by storing it in a portable bag that matches the rod-shaped outer shape of the mask 10.

  Moreover, since it is folded in the shape of a rod, there is an advantage that the shape of the mask is not easily collapsed. Furthermore, the skin inside the mask 10, particularly the portion that will be in contact with the mouth and nostril, is hardly exposed to the outside in the folded state, and therefore is hardly sanitized and extremely hygienic.

  When the mask 10 is mounted, each of the upper ridge 22a and the lower ridge 22j is pinched with both hands and pulled up and down to easily open the folds other than the joint portions 24a and 24b at the folds, FIG. As shown in FIG. As shown in FIG. 4 and FIG. 5, by joining the two sides other than the upper and lower bases of the trapezoidal shape at the joints 24 a and 24 b, when wearing the mask 10, The formed cup-shaped space can be made sufficiently large.

  At the same time, the ridges 22a to 22j are trapezoidal, and the ear strap 30 is attached to the corners of the bottom end of the trapezoid of the joints 24a and 24b of the main body 20, so The gap with the mask 10 becomes extremely small, and sufficient adhesion is ensured.

  FIG. 6 is a photograph at the time of mounting an example of the mask of the embodiment. It can be seen that the cup-shaped space formed at the wearer's mouth can be made sufficiently large, and the adhesion to the nose, cheeks, and chin is also ensured.

  7 to 10 are photographs showing the operation of an example of the mask of the embodiment. For example, in order to discard the mask 10 after mounting, the folding method when the mask is folded is shown continuously.

  As shown in FIG. 8, the mask 10 that has been mounted can be easily folded as shown in FIG. 10 by holding the joints 24a and 24b with both hands and pulling them to the left and right. . This is an effect caused by forming the trapezoids 22a to 22j into trapezoids and joining the two sides other than the upper and lower bases of the trapezoids of all the trapezoids at the joint portions 24a and 24b.

  Further, when the mask is folded, it can be folded without touching the skin inside the mask 10, particularly the portion in contact with the mouth or nostril, which is extremely hygienic. Further, in the folded state of the mask, the skin inside the mask 10, in particular, the portion in contact with the mouth and nostril does not touch outside except the fold. Therefore, since the adhesion of dirt from the mask 10 is suppressed, it is extremely hygienic.

  Even when a mask once used is carried and reused, it is useful in that it is compact, hygienic and can be carried without losing its shape.

  As described above, according to the present embodiment, it is possible to realize a mask that improves the adhesion between the mask and the face, and is compact, hygienic, and portable without losing the shape.

  The embodiments of the present invention have been described above with reference to specific examples. The above embodiment is merely given as an example, and does not limit the present invention. In the description of the embodiment, the description of the portions that are not directly required for the description of the masks and the like is omitted, but elements related to the required masks and the like can be appropriately selected and used.

  For example, in the embodiment, the number of wrinkles is 10, but the number is not necessarily limited to 10.

  Further, for example, in the embodiment, the case where a plurality of trapezoidal trapezoids have the same trapezoidal height, that is, the depth of the trapezoid, has been described as an example. From the viewpoint of making the mask size during storage compact, it is desirable that the heights are equal, but the heights may be different.

  In addition, all masks that include the elements of the present invention and can be appropriately modified by those skilled in the art are included in the scope of the present invention. The scope of the present invention is defined by the appended claims and equivalents thereof.
