It is a region more elastic than the region 1, and is located on the nose and chin of the user when the mask wearing aid is superposed on the filter of the sanitary mask.

According to the present invention, the worn hygiene mask can be fitted to the user's face shape, and the gap between the filter and the face can be suppressed.

It is a figure which illustrates the mask wearing assistance tool 1 in Example 1. FIG. It is a figure which illustrates the mask wearing auxiliary tool 1 superposed on the hygiene mask. It is a perspective view which illustrates the use state of the mask wearing auxiliary tool 1 in Example 1. FIG. It is a figure which illustrates the mask wearing auxiliary tool 100 in Example 2. FIG. It is a figure which illustrates the mask wearing auxiliary tool 200 in Example 3. It is a figure which illustrates the modification in Example 1. FIG.

First, the background of the present invention will be described.
Sanitary masks (hereinafter sometimes abbreviated as masks) protect the nose and throat from cold air and dryness, prevent the scattering of secretions from the mouth and nose, or pollen and pathogens in the air. It has the effect of preventing the suspended matter from being taken into the body.
Currently, in the above mask, a non-woven fabric type having a rectangular filter shape is common. The non-woven fabric type mask has a plurality of pleats along the longitudinal direction of the filter in the lateral direction, and when worn, when the central part of the mask body is picked and pulled in the vertical direction, the pleats in the closed state gradually become. It can be expanded to cover from the nose to the jaw.

However, the non-woven mask cannot sufficiently follow the contour of the face that differs for each individual, and a gap is created between the filter and the face. Has a drawback that sufficient airtightness cannot be ensured, such as leakage. The generation of gaps above and below and to the left and right of the mask reduces the amount of air passing through the filter in the front direction of the mask, which causes the original filtering function of the mask to not be fully exhibited, which is a big problem.

For example, Patent Document 1 proposes a disposable dust mask in which a flexible portion is provided on a main body instead of a three-dimensional shape so that the main body and the face are brought into close contact with each other. The mask described in Patent Document 1 is intended to improve the adhesion to the face and the wearing feeling by providing a stretchable bent portion on the entire circumference of the lower peripheral edge of the shape-retaining filter in the mask face body. However, the mask described in Patent Document 1 uses a non-woven fabric made of synthetic resin fibers having a predetermined hardness as a bent portion of the shape-retaining filter. For this reason, the shape-retaining filter cannot have the flexibility to adhere to the size of each individual's face and the complicated undulations of the face, and there remains a problem in the wearing feeling of the mask. Furthermore, due to its structure, the mask itself has a large appearance, making it unsuitable for use in daily life.

Further, Patent Document 2 proposes a mask inner that is used by attaching a mask inner between the sanitary mask and the face to improve the efficiency of virus collection. However, since the mask inner described in Patent Document 2 covers the mouth and nostrils, the air permeability to the mouth and nose is lowered as compared with the case where only the mask body is used. The decrease in air permeability not only leads to the wearer's suffocation, but also promotes the flow of air from the top, bottom, left and right of the mask, which may rather reduce the original filtration performance of the mask.

Therefore, the embodiment of the present invention has been created with the above circumstances as the first point of view. According to the embodiment of the present invention, the hygiene mask is fitted to the user's face shape and the gap between the filter and the face is suppressed, so that the worn mask and the face can be held while maintaining the ease of breathing. It is possible to suppress the invasion of foreign matter and the leakage of exhaled breath from the gaps generated between them.
Hereinafter, the mask wearing assisting tool according to the embodiment of the present invention will be described with reference to the drawings. It should be noted that all of the embodiments described below show a specific example of the present invention. Therefore, among the components in the following embodiments, the components not described in the independent claims are described as arbitrary components.

The processed yarn is also not particularly limited, and is not particularly limited, and is false twisted yarn (Woolly processed yarn, DTY, improved false twisted yarn, etc.), pressed yarn, shaped yarn, scraped yarn, Taslan yarn, yarn. Long-difference aligned processed yarns, composite processed yarns, fluff processed yarns, entangled focusing yarns, entangled mixed yarns, and the like can be used. The cross-sectional shape of the fiber is also not particularly limited, and examples thereof include a round shape, a triangular shape, a star shape, a flat shape, a C shape, a hollow shape, a well shape, and a dock bone.

In addition, the structure of the cloth material may be any form such as a woven fabric such as plain weave, twill weave, satin weave, knitted fabric such as warp knitting, weft knitting (horizontal knitting or circular knitting), or non-woven fabric. You may. As the structure of the cloth material, a knitted material is preferable from the viewpoint that stretchability can be imparted to the mask auxiliary tool 1 and the ease of wearing and the adhesion to the face can be improved. Further, the auxiliary tool base 10 is annular and preferably has a width of 0.5 cm or more and 4 cm or less from the viewpoint of the strength of the mask auxiliary tool. The auxiliary tool base 10 of this example is a cloth material which is a knitted structure.

Further, the auxiliary tool base 10 is a colorant such as a dye or a pigment, a matting agent such as titanium oxide, an antioxidant, a stabilizer, a colorant, a flame retardant, and an antistatic agent, as long as the intended purpose is not deviated. Various functional agents such as agents, heat resistant agents, antibacterial deodorants, antibacterial agents, antiviral agents, SR agents, inorganic particles, dyeing aids, moisturizers, hygroscopic agents, water repellents, and fragrances are contained in the base material. It may be attached to the surface of the substrate or the substrate. The functional agent may be used alone or in combination of two or more, or may be combined with a binder for the purpose of improving the adhesion amount and preventing the adhered agent from being detached.

In particular, it is preferable that a harmful substance inactivating agent such as a deodorant, an antibacterial agent, an antiviral agent, and an antiallergen is attached to the surface of the base material. Specifically, amphoteric substances such as aluminum sulfate and zinc oxide, precious metals such as silver and copper, particles supporting them on zeolite and activated charcoal, photocatalysts such as zinc pyrithione, tannic acid, titanium oxide and tungsten oxide. The harmful substance inactivating agent may be used alone or in combination of two or more, and is preferably combined with a binder for the purpose of improving the adhesion amount and preventing the adhered agent from being detached. In the auxiliary tool base 10 of this example, a harmful substance inactivating agent such as a deodorant, an antibacterial agent, an antiviral agent, and an antiallergen is attached to the surface of the cloth material which is the base material.

Further, as a method of adhering the functional agent to the surface of the base material of the auxiliary tool base 10, a treatment liquid in which the functional agent, the colorant, and the auxiliary agent such as a binder are dissolved or dispersed in water is prepared, and the above-mentioned The treatment liquid may be applied to the base material by dipping, spraying, coating, etc., and dehydrated or dried to attach the functional agent to the surface of the base material. When a binder is used in combination, cross-linking may be promoted by heat treatment, irradiation with active energy rays, graft polymerization by wet heat treatment, or the like. When a plurality of the above-mentioned various types of processing are performed, a plurality of functional agents may be added to the treatment liquid for batch processing, or the treatment liquids may be prepared separately and processed in stages.

The hole portion 12 is a through hole provided in the thickness direction of the auxiliary tool base portion 10. As illustrated in FIG. 2B, the hole 12 is provided at a position where the user's nostrils and lips are present when the mask auxiliary tool 1 is superposed on the filter of the sanitary mask. The hole 12 is larger than half the size of the nostrils and lips of the user wearing the mask wearing aid 1 and smaller than the filter of the sanitary mask illustrated in FIGS. 2 (A) and 2 (B). .. When the size of the hole 12 is smaller than the size of the nostrils and lips, the auxiliary tool base 10 closes at least a part of the nostrils and lips, but the auxiliary tool for masking when breathing through the nose or mouth. It suffices as long as 1 does not interfere with breathing. Here, the filter of the sanitary mask of this example is a rectangular filter of a general non-woven fabric mask for adults, and has a size of, for example, 10 cm in length and 18 cm in width with the pleats closed. The hole 12 in this example has an isosceles triangle with a base of 8 cm and a height of 5 cm, for example, the virtual line connecting the corners of both mouths of the user as the base and the virtual line connecting the tip of the nose and the lips as the height. In other words, the size of the triangle is larger than it can be contained, and it is smaller than the size contained in the rectangular filter with closed pleats. Of course, the size of the hole 12 may be appropriately set according to the size of the wearer's face and the filter size of the mask to be overlapped.

The ear hook portion 20 is a member provided on both sides of the auxiliary tool base portion 10 and formed of a stretchable sheet material or a string material. In the ear hook portion 20 of this example, one of the auxiliary tool bases 10 illustrated in FIG. 1 is referred to as an ear hook portion 20A, and the other of the auxiliary tool base 10 is referred to as an ear hook portion 20B. When it is not necessary to distinguish between them, it is simply referred to as the ear hook portion 20. The ear hook portion 20 is a knitted fabric having the same elasticity as the auxiliary tool base 10, and since one is connected to the upper end side of the auxiliary tool base 10 and the other is connected to the lower end of the auxiliary tool base 10, the auxiliary tool base 20 is assisted. It is integrally formed with the tool base 10.
Further, the ear hook portion 20 may be joined, sutured, or heat-sealed to the auxiliary tool base 10 with an adhesive or the like, or may be in the form of passing a string through a string through hole provided at the end of the auxiliary tool base 10. .. Further, it may be integrally formed with the auxiliary tool base 10 by die cutting, sewing-free knitting, or the like. It is most preferable that the ear hook portion 20 is integrally formed with the auxiliary tool base portion 10. As a result, the effect of improving the airtightness can be further exerted, and at the same time, the discomfort when the ear hook portion 20 is worn over the ear can be reduced.

The fixing portion 30 is a fixing member that is arbitrarily provided at positions such as the upper portion and the lower portion of the auxiliary tool base portion 10 and prevents misalignment with the filter of the sanitary mask when worn in layers. The fixing portion 30 detachably fixes the auxiliary tool base 10 to the filter in a state where the auxiliary tool base 10 is superposed on the filter of the sanitary mask. The fixing portion 30 is, for example, a wire, double-sided tape, a hook-and-loop fastener, a clip, or the like. The fixing portion 30 of this example is a wire. For example, in the case of the upper part of the auxiliary tool base 10, the auxiliary tool base 10 and the filter are brought into close contact with each other by deforming according to the outer shape of the nose. In the case of the lower part, the auxiliary tool base 10 and the filter are brought into close contact with each other by deforming according to the outer shape of the jaw. The fixing portion 30 can be omitted.
