  The present invention relates to an economical, hygienic and wearable mask that can be used repeatedly by washing, which is suitable when a mask needs to be worn every day for a long time such as in a food factory.

In food factories, work clothes, hats and masks are essential for hygiene. Since these are worn every day and for a long time, it is desired that they are not only substantially hygienic, but also important in terms of comfort and wearing, and economically inexpensive. In addition, it is preferable that the appearance of white and other stains can be readily seen and give a clean impression.
Of these, non-woven cloth disposable masks are becoming more popular than conventional gauze masks, as non-woven fabric processing technology has advanced.
However, in recent years, with the increase in allergic patients, the number of users of masks has increased, and further, it has become difficult to secure a disposable mask as the use of masks is encouraged as a countermeasure against influenza. While the use of masks has increased dramatically in this way, it is not preferable from an environmental and economic viewpoint to use a disposable mask every day.

As a mask in which a nonwoven fabric sheet is arranged on the inner side of a cloth mask body, Patent Document 1 states that “a nonwoven fabric sheet is used as a mouth cloth on the inner side of a mask body that has an ear hook part and is formed by sewing a woven or knitted fabric. It is characterized by being arranged ". Patent Document 2 states that “a mask main body that covers a target portion of a face including the nose and mouth that can swell forward with respect to the face covering the nose and mouth, and left and right side portions of the mask main body.

FIG. 3 is a back view showing the side that contacts the mouth when the mask is folded. FIG. 4 is a view in which a mouthpiece sheet is attached when the mask is folded. FIG. 5 is a photograph of the surface where the mask is three-dimensionally opened. FIG. 6 is a photograph of the back surface that hits the mouth in which the mask is three-dimensionally opened. FIG. 7 is a view showing another embodiment in which the mask mounting rubber is turned to the back of the head.

The present invention is a mask comprising a mask body covering a human nostril and ear hooks provided on the left and right sides of the mask body, and is configured by sewing a woven fabric of cotton and chemical fiber, It has a dome-like three-dimensional structure when spread, and has at least two fold-like folds so that it returns to a flat shape when closed, and a removable contact sheet is arranged inside the mask body. It is a mask.
In the present invention, the mask body is composed of a woven fabric, and the fabric is not particularly limited, such as cotton, silk, wool, polyester, rayon, and acetate. However, a fabric having strength and elasticity that can withstand washing is preferable, and a twill (T / C) fabric, a woven fabric of 15th to 30th fabric, a blend of 65% cotton 35% polyester to 80% polyester 20% cotton is preferable. Although this cloth is produced in a non-dyed state, it is preferable to use a cloth dyed white with a hygienic and clean feeling when used in food factories.

  The nonwoven fabric as a mouthpiece sheet used by this invention is not specifically limited. For example, trade names Airlaid, Spunlace, Spunbond, etc., manufactured by Tokai Processed Paper Co., Ltd. can be used. There are various types of mouthpiece sheets, hard paper, soft ones, thick ones and thin ones, but the feelings of use vary. A comparative example is shown in Table 1.

  The rubber for mounting the mask used in the present invention is not particularly limited. Preferably, four string-like raw rubbers having a diameter of 0.8 mm are knitted into 20 pieces of polyester yarns one by one, and four rubbers are made into a belt shape. The rubber strap is antibacterial and has an antibacterial effect even after washing. As a feature, it is soft to the touch, and even if the mask is worn for a long time, the ear does not hurt easily. It is excellent in elasticity, strength and durability, and can be used after washing repeatedly. Even people who are prone to rough skin are less likely to get rough due to antibacterial effects. It is easy to put on a person with a large face with a stretch rate of 250%.

A structure having at least two fold-like folds, which is a feature of the mask of the present invention and maintains a dome-like three-dimensional structure when spread and returns to a flat shape when closed, will be described with reference to the drawings.
The first embodiment is a mask shown in FIGS. 1 to 4 and has three fold-like folds. Any number is acceptable as long as it fits the face, but 3 to 4 is suitable. As shown in FIG. 1, it has the crease | fold 3, and is sewn and pressed with the stitch 2 from above the crease | fold so that this crease | fold may be fixed. A hook-and-loop fastener 5 for fixing the mouthpiece sheet 6 is fixed to the upper portion of the mask that is in contact with the mouth, and the mouthpiece sheet 6 can be attached and fixed to the hook-and-loop fastener 5 (FIG. 4). As the surface fastener, Kuraray Co., Ltd. Velcro (registered trademark) or the like can be used. By widening the crease 3 of the mask body 1, the mouth and nose portion is fixed by the mounting rubber portion 4 while maintaining the dome-like three-dimensional structure. The width of the mask main body is preferably 14 cm to 20 cm, and the vertical width is preferably 8 cm to 12 cm so as to wrap the mouth and nose with the slipper. The size of the mouthpiece sheet is preferably a size that does not protrude when the mask body is folded. When the mask body is worn, the fold-like folds of the body spread and extend, but the lower half is in a state that wraps the chin, so the mouthpiece sheet should be fully covered with a mouthpiece sheet that matches the size when folded. it can. The hook-and-loop fastener is durable and preferable, but may be fixed with an adhesive or the like.

  The mask body 1 has a fold-like crease 3 in the direction from the nose to the mouth. As shown in FIG. 2, the crease is folded so that the surface (back surface) that contacts the mouth becomes a downward bag shape. When the mask is opened and installed in a dome shape, this fold serves as a bag-like saucer, and can catch small dust or hair attached to the face. The width between the creases (in FIG. 1, the distance between the ridges and the ridges and the distance between the valleys and the valleys) is preferably 1 cm to 2 cm, and particularly preferably 1.5 cm to maintain steric stability. The stitch 2 is held 1 mm to 5 mm above the end so that the crease is fixed. It is more preferable that the front surface of the mask is firmly stitched from the right end to the left end of the mask as shown in FIG. 1, and the back side of the mask is left 1 cm to 2 cm at the left end of the right end portion without being stitched as shown in FIG. This can further increase the stability when the mask is opened in a dome shape. Instead of this stitch, the woven fabric can be pleated.

The mask of the present invention can be used by sewing a wire on the upper portion of the hook-and-loop fastener 5. When the mask body is mounted on the mouth and nose, the adhesion of the mask body and the mounting feeling of the mask body are increased by attaching the wire to the shape of the nose so that there is no gap in the nose. As the material used for the wire, a wire, a plastic resin, a shape memory alloy, or the like is used.
The rubber or string for fixing the mask to the face may be attached in any form as in a normal mask. A type in which rubber is fixed to both ends of the mask body and applied to the ear, or a type in which the upper and lower ends of the mask body are connected with rubber and applied to the head is common. Depending on the purpose, it may be tied with a string.

  The invention product thus completed has a dome shape as shown in FIG. Since the main body maintains a three-dimensional shape without difficulty, even if it is used for a long time, there is little burden on the user's face and the feeling of use is good. The mask body can be washed and will not lose its shape no matter how many times it is washed, and it will be three-dimensionally stable when used. The flat shape makes it easy to iron after washing. Thus, it is excellent in convenience, economical and sanitary.

As shown in FIG. 6, the back surface that hits the mouth of the invention is a dome-shaped concave surface, and the mouthpiece sheet is adsorbed to the mask body so that it does not shift or protrude during use. When disposable masks are no longer available due to the anticipated outbreak of influenza, the product of the present invention can be used repeatedly by replacing only the mouthpiece sheet. Also, even in situations where there is a shortage of mouthpiece sheets, kitchen paper, tissue paper, dressmaking nonwoven fabric, sanitary products, etc. can be used as substitutes for mouthpiece sheets to cope with emergencies.
