  The general three-dimensional mask shown in Patent Document 1 is built so as to follow the shape of the lower part of the wearer's face. It does not increase.

  In addition, since the pleated mask shown in Patent Document 2 has a pleat formed on the mask body, the shape can be changed according to the size of the face as compared to a three-dimensional mask. it can.

  The pleated mask has a rectangular shape when the mask body portion is attached to the ear of the wearer and the nose fitter of the mask body portion is deformed along the shape of the nose. Therefore, the upper end portion of the mask main body from the both ends of the nose fitter to the both ends in the lateral direction is positioned in the vicinity of the cheekbone.

  While working with the pleated mask attached, the wearer may feel uncomfortable if the mask is displaced and the upper end of the mask body enters the position of the lower eyelid. Moreover, since the force which presses down the upper end part of a mask main-body part at the time of mounting | wearing of a pleat type mask is weak, there exists a possibility that a feeling of adhesion may fall.

  The object of the present invention is to change the shape according to the size of the wearer's face, and to increase the feeling of adhesion without feeling uncomfortable when the wearer wears for a long time. It is to provide a pleated mask.

  The pleated mask according to the present invention is provided at each of a mask main body portion on which a pleat that covers a target portion of a wearer's face and can be expanded in the vertical direction, and both lateral end portions of the mask main body portion. An ear hook part, and the mask main body part is a rectangular part to which the ear hook part is attached, a nose fitter capable of changing the shape so as to straddle the wearer's nose, and And a trapezoidal trapezoidal part having a nose fitter adjacent to the rectangular part.

  Further, in the pleated mask according to the present invention, the nose fitter has a core portion extending in a lateral direction, and the core portion is rounded at least at a corner located on the side opposite to the rectangular portion side. Preferably it is.

  Further, in the pleated mask according to the present invention, the rectangular portion and the trapezoidal portion are constituted by a single rectangular member, and the trapezoidal portion is the side on which the nose fitter is provided. It is preferably formed by bending at the corners.

  According to the present invention, since the upper end portion of the mask main body portion has a trapezoidal portion formed obliquely, even when the wearer wears it for a long time, the feeling of discomfort is enhanced and the feeling of adhesion is further enhanced. Can do.

  Embodiments according to the present invention will be described below in detail with reference to the accompanying drawings. Below, the same code | symbol is attached | subjected to the same element in all the drawings, and the overlapping description is abbreviate | omitted. In the description in the text, the symbols described before are used as necessary.

  FIG. 1 is a front view of the pleated mask 10 in a folded state. FIG. 2 is a rear view of the pleated mask 10 in a folded state. The pleated mask 10 includes a mask body 12 and an ear hook 14. The pleated mask 10 is a mask that is worn by changing its shape according to the size of the wearer's face and prevents dust, pollen, viruses, and the like from entering the body through the nose and mouth.

  The mask main body 12 is formed with pleats that cover the nose and mouth located at the lower part of the wearer's face and can spread in the vertical direction. The mask main body 12 is composed of a single rectangular member 15. The size of the single rectangular member 15 is set in consideration of the size of the wearer's face. For example, the lateral direction is preferably about 100 to 190 mm, and the longitudinal direction is preferably about 50 to 100 mm, more preferably. Means that the horizontal direction is about 170 mm and the vertical direction is about 90 mm.

  The mask main body 12 can be composed of a breathable sheet member, for example, a nonwoven fabric, and further can be composed of a nonwoven fabric formed by a spunbond method, a melt blow method, a thermal bond method, or a spunlace method. Is preferred.

  The structure of the mask body 12 can be a sheet member having one or more layers. For example, an S layer (single layer of spunbond), an SS layer (two-layer structure of spunbond / spunbond), an SMS layer (spun) Bond / melt blow / spun bond three-layer structure).

  At least one pleat is formed on the mask body 12. The pleat is formed by folding the sheet member at at least two folds extending in the lateral direction of the mask main body 12. By expanding the pleats, the mask body 12 can be expanded and contracted in the vertical direction (vertical direction) to accommodate various face sizes. The pleats can be formed either upward or downward as viewed from the front, and the number of pleats is not limited, but the mask body 12 expands and contracts as the number increases.

  The mask main body 12 includes a rectangular portion 16, a nose fitter 18, and a trapezoidal portion 20. The rectangular portion 16 has a rectangular shape to which the ear hooking portion 14 is attached. The rectangular portion 16 is located below the entire area of the single rectangular member 15, and the vertical direction occupies 80 to 90% of the entire length of the rectangular member 15. When the length is about 170 mm and the vertical direction is about 90 mm, the length in the vertical direction is preferably about 75 mm.

  The nose fitter 18 is a member that can change its shape so as to straddle the wearer's nose. The nose fitter 18 has a core portion 22 extending in the lateral direction. The core portion 22 is made of a flexible material, and a gap formed between the upper portion of the mask main body portion 12 and the nose is deformed so as to conform to the shape of the wearer's nose when worn. Can be suppressed.

  As shown in FIG. 1, the core portion 22 has a substantially flat plate shape, but is formed with rounded corners at the lateral ends. The length of the nose fitter 18 is preferably about 50 to 100 mm. When the horizontal direction of one rectangular member 15 is about 170 mm and the vertical direction is about 90 mm, more preferably about 85 mm. That is.

  The trapezoidal portion 20 is adjacent to the rectangular portion 16 and has a trapezoidal shape having a nose fitter 18. The trapezoidal portion 20 is formed by bending one rectangular member 15 at a corner portion on the side where the nose fitter 18 is provided. Here, since the corner portion 22 is formed with rounded corners as described above, after being bent, the core portion 22 has a pulling force near the end portion of the nose fitter 18 during use of the pleated mask 10. It is possible to prevent the trapezoidal portion 20 from being broken by the end portion of the nose fitter 18 when. Further, when a single rectangular member 15 is bent and formed, heat welding or the like is performed as described later, but the joining region in the region near the end of the nose fitter 18 is increased to reinforce or have an appropriate strength. The trapezoidal portion 20 can be made more difficult to break during use of the pleated mask 10 by adding a reinforcing member and performing reinforcement by welding.

  The trapezoidal portion 20 is located at the upper part of the entire area of the single rectangular member 15, and the vertical direction occupies 10 to 20% of the entire length of the rectangular member 15. When the length is about 170 mm and the vertical direction is about 90 mm, the length in the vertical direction is preferably about 15 mm. At this time, the length of the upper base of the trapezoidal portion 20 is about 70 mm, and the length of the lower base of the trapezoidal portion 20 is about 170 mm.

  The ear hooks 14 are respectively provided at both lateral ends of the mask main body 12. The ear hooking portion 14 is a string-like member having elasticity, and is made of, for example, spandex (polyurethane elastic fiber). Here, the ear hook 14 has a round cross-sectional shape. For example, the ear hook 14 has a flat plate shape to increase the contact area with the skin of the wearer and acts on the ears and cheeks when worn. It is possible to reduce the wear and enhance the wearing feeling.

  Next, a method for manufacturing the pleated mask 10 will be described. FIG. 3 is a diagram showing a procedure for manufacturing the pleated mask 10. First, a single rectangular member 15 is formed in which the horizontal direction is about 170 mm, the vertical direction is about 90 mm, and the nose fitter 18 is disposed at the upper center (S2). Next, the two ear hooks 14 are arranged in the region where the rectangular part 16 is formed at both lateral ends of one rectangular member 15 and bonded by thermal welding or the like, as shown in FIG. The mask shown is formed (S4).

  Next, in one rectangular member 15, the corner on the side where the nose fitter 18 is provided so as to form a trapezoidal portion 20 having an upper base length of about 70 mm and a lower base length of about 170 mm. In FIG. 3B, the sheet is bent along the mountain fold line 13 shown in FIG. 3B, and bonded by heat welding or the like (S6). Thus, the rectangular portion 16 is formed together with the trapezoidal portion 20, and the pleated mask 10 shown in FIG. 3C is completed.

  Next, the operation of the pleated mask 10 will be described. FIG. 4 is a diagram showing a state in which the pleated mask 10 is mounted on the lower part of the wearer's face. FIG. 5 is a diagram showing that the pleated mask 10 has a higher adhesion than the conventional mask. The wearer wears the pleated mask 10 so that the ear hooks 14 are respectively put on the ears, and the pleats are opened to cover the nose and the mouth. At this time, the nose fitter 18 is deformed so as to follow the shape of the nose and the pleated mask 10 is brought into close contact therewith.

  Here, as shown in FIG. 4, since the space region 25 formed by bending the corners is formed as compared with the conventional mask, the pleated mask 10 is slightly shifted upward. However, there is no sense of incongruity in the lower arm. In addition, since the space region 25 is formed, there is an effect that the lower field of view can be expanded. Furthermore, there is an advantage that it is more compact than a conventional mask and an apparent small face effect can be obtained.

  Further, in the conventional mask, as shown in FIG. 5A, the force generated by using the end of the nose fitter 18 as a fulcrum, that is, the force generated by the pulling force of the ear hook 14 is only in the lateral direction. There is a problem that the force decreases and the adhesion decreases as it goes toward the corner.

  However, in the pleated mask 10, as shown in FIG. 5 (b), the force generated by supporting the end of the nose fitter 18 is decomposed in the downward direction and the diagonal direction. A force is applied in the direction along the shape of the nose to attract the trapezoidal portion 20, thereby improving the adhesion. Further, since the thickness is increased by turning the corner portion, there is an advantage that the adhesion can be further improved. Thereby, there is an advantage that upward expiratory airflow can be suppressed and fogging of glasses can be suppressed.

  Furthermore, since the pleated mask 10 can be formed by bending the corners of one rectangular member 15 as described above, a production line for manufacturing a conventional pleated mask can be used. There is an advantage that it can be manufactured at low cost.

  Although the pleated mask 10 has been described as being formed by bending the corners of one rectangular member 15 in this way, the pleated mask 10 is completed by cutting without bending to form a trapezoidal portion 20. It can also be made.

10 pleated mask, 12 mask body, 14 ear hook, 15 rectangular member, 16 rectangular, 18 nose fitter, 20 trapezoid, 22 core.
