Abstract

PROBLEM TO BE SOLVED: To provide an inexpensive and functional disposable mask with a small quantity of material and a short working process by providing the length adjusting function of string parts to be set to the ears when punching and cutting an air-permeable sheet material. SOLUTION: Both of the side edges of the air-permeable sheet material are cut as curved inward, and notches (2) are formed in the inside of them. This notches (2) are folded back outward to make the string (3) to be set to the ears. The strings (3) has length adjusting pieces (5) projecting outward extended at the center of the curved and cut side edges and has the length adjusting function obtained by providing sewing machine stitches (4) at the pieces (5) from the position to be in contact with the ears when the mask is used.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposable mask in which a mask main body portion and an ear hook string portion are integrally formed by punching and cutting an air permeable sheet material and the length of the ear hook string portion can be adjusted. .

[0002]

2. Description of the Related Art Conventionally, various masks in which a main body of a mask made of a breathable sheet material and an ear hook string portion are integrally formed are known, but a mask having a function of adjusting the length of the ear hook string portion is known. The following are known. (A) The device disclosed in Japanese Utility Model Laid-Open No. 4-75555 discloses a device in which a cut is made in the middle of the ear hook string portion to separate it, and the elastic member is bonded thereto. (B) The invention of Utility Model Registration No. 2580356 is made of one-way stretchable composite fabric, and the entire mask is stretchable. (C) In the invention of Japanese Utility Model Laid-Open No. 6-66708, pleats for widening in the vertical direction are processed and formed on the face contacting surface of the mask and the ear hook string portion.

[0003]

This has the following drawbacks. In the above-mentioned (a) Japanese Utility Model Laid-Open No. 4-75555, there is a process such as making a cut in the ear hook string part and adhering the elastic member, which requires a work and a high material cost. . Further, (B) The invention of Utility Model Registration No. 2580356 has excellent wearing feeling because it uses an elastic cloth, but the material cost is high. Furthermore, the device of (C) Japanese Utility Model Laid-Open No. 6-66708 requires the work for forming pleats, and the material cost increases because the amount of materials used increases. The present invention has a function of adjusting the length of the ear hook string portion at the time of punching and cutting the breathable sheet material, shortens the working process with less material, and provides an inexpensive and excellent disposable mask. It is intended.

[0004]

According to the mask of the present invention, both sides of the breathable sheet material are curved inwardly and cut out, and a notch (2) is provided inside. The notch (2) is folded back outward to form the ear hook string (3). Further, the ear hook string (3) projects outwardly at the central portion of the side that is curved and cut out so that the length adjusting piece (5) is extended so as to match the width of the face of the user, The perforation (4) is provided on the length adjusting piece (5) from the position where it touches the ear during use. Alternatively, the perforation (4) is provided at both ends of the notch (2) to have a length adjusting function. The present invention is a mask having the above configuration.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. In the present invention, as shown in FIG. 1 and FIG. 3, both sides of the breathable sheet material are curved inwardly to make notches, and inwardly curved to form notches (2). The notch (2) is folded back outward to form the ear hook string (3). The ear hook string (3) has a length adjusting function so that it can be adjusted to the width of the face of the user. As shown in FIG. 1, the mask according to claim 1 is an ear hook string (3) of a breathable sheet material which is curved and cut inward.
The length adjustment piece (5) is extended and protruded outward at the center of the side that becomes, and the perforation (4) is provided on the length adjustment piece (5) from the position that touches the ear when in use. Can be adjusted. Further, as shown in FIG. 3, the mask according to claim 2 is provided with extended perforations (4) at both ends of the notch (2) which becomes the ear hook string (3) of the breathable sheet material. The height can be adjusted. The perforations (4) for adjusting the length may be formed by providing small holes in a dot shape. Further, in any case, when the breathable sheet material is used in a multi-layer structure, it is preferable to fix the periphery of the sheet by thermocompression bonding or the like in order to prevent misalignment.

The present invention has the above-mentioned structure. When using this structure, first, the ear hook string (3) provided by the notch (2) is held, and the ear hook string (3) is folded outward and hooked on the ear. At this time, if the width of the face of the user is equal to or larger than the reference dimension, the perforation (4) is cut open to adjust the length as shown in FIGS. 2 and 4. In this way, an excellent wearing feeling that fits the user's face can be obtained.

Further, since the reference dimensions and the maximum extension dimensions are the same in the respective embodiments of the present invention shown in FIGS. 1 and 3, the materials used are compared as follows. As can be seen from this figure, in the embodiment of FIG. 1, since the length adjusting piece (5) is provided in the notched portion, the perforation (4) is provided by extending it to the standard size. A mask of the same size can be manufactured using less material than the third embodiment.

[0008]

Since the present invention is constructed as described above, it has the following effects. (A) The ear hook string portion is provided on the mask body side by being curved,
Since this is folded back outwards and used, the required size of the ear hook string portion can be obtained with about ½ the material. This can be provided at a lower cost than the conventional one. (B) Also, since it folds outward and hangs on the ear, it fits well on the face due to the repulsive force of the folded back portion. (C) Since the shape of the ear hook string is curved inward and cut out, a length adjusting function can be provided. This fits the width of the user's face and is therefore comfortable to wear.
