Description

The present invention relates to a mask that is used to cover the nostril area and the lip area of the wearer's face, and in particular, does not allow lipstick to stick to the inside of the mask, avoiding discomfort due to dirt on the inside of the mask, and is clean and comfortable to use. To provide a mask that can be worn and the upper side of the mask does not fall under the nose.

So-called masks are widely used to prevent the spread of various viral diseases, including colds, to suppress droplets from coughing and sneezing, and to suppress and alleviate allergic symptoms such as pollen and house dust. ing.
In addition, this type of mask is used for various purposes such as preventing dust from entering the nose in a dusty environment and preventing drying of the mucous membrane of the respiratory system.

Most masks of this type are generally rectangular strips of woven fabric or nonwoven fabric, paper fabric, or the like, and have ear hooks attached to both the left and right ends of the wearer's face. Among those using materials such as woven cloth and urethane sponge, two sheet-like materials are joined symmetrically, and when worn, the parts corresponding to the nostril area and the lip area bulge outward. There are also three-dimensionally sewn masks to improve the adhesion between the face and the outer edge of the mask, to facilitate breathing and to form bulges in front of the nostril and lip regions to make it easier to talk.
In addition, there are masks made of non-woven fabric, in which a plurality of pleats are formed on the mask body to provide adhesion and ease of breathing. Furthermore, as a mask with a simple structure, there is also a mask that is three-dimensionally cut from a sponge sheet such as polyurethane.

In particular, for thin masks made of non-woven fabric, metal strips are embedded near the upper side of the mask body to fit the raised shape of the nose and reduce the gap between the mask and the face. is also common.

In this way, the mask should be in close contact with the wearer's face to prevent direct inhalation of outside air so that it can fully demonstrate its function of preventing viruses, bacteria, pollen, and dust from entering the body through the nostrils. , and restrains the exhaled air from being discharged directly to the outside.

However, since the inside of the mask is in direct contact with the wearer's face, cosmetics applied to the face are likely to adhere to the mask, and runny nose and residue from meals may adhere to the mask, making reuse difficult. Furthermore, in recent years, in order to prevent the spread of infection, it has become necessary to wear masks all day long.

With low-priced masks such as non-woven fabrics, dirty masks are often discarded and new masks are used rather than being reused. However, in addition to wasting resources, non-woven masks, which are considered illegally discarded in recent years, have caused pollution of rivers and oceans, adversely affecting the survival of living things. giving a load.

On the other hand, cloth masks are said to be less effective in suppressing the spread of droplets, and in an increasing number of cases, a non-woven fabric filter is inserted between the inside of the mask and the mouth to prevent the spread of droplets.
However, even if a rectangular non-woven fabric filter is placed inside a three-dimensionally sewn cloth mask, it is not stable and sticks to the lips or shifts during conversation, halving the effect. There is also the problem of storage.

In addition, when a runny nose does not stop due to a cold or pollen allergy, there are many cases in which tissue paper or the like is stuffed inside the mask.
However, if the tissue paper is pushed in, it will curl up due to the moisture inside the mask, or it will slip and protrude outside the mask, not only not being able to perform its nasal mucus absorption function adequately, but also making it look terrible. .

In order to solve the above problems, there is a conventional technique for taking measures against contamination inside the mask.
Patent document 1 and patent document 2 can be mentioned. Patent Document 1 is configured by fixing a cloth (referred to as a facial cloth) preferably made of nonwoven fabric of synthetic fibers (polypropylene, polyester, etc.) to the top, bottom, left, and right inside the mask body, and is mainly used for removing makeup for women. To disclose a mask that can be worn for a long time without worrying about retouching makeup.

Further, Patent Document 2 discloses an inverted trapezoid plate-shaped spacer cover having a ventilation hole and having an upper side overlapped and fixed to the upper side of a mask so that the lower side is in front of the wearer's lip area. It is described that this space-retaining cover does not interfere with vocalization, is resistant to dirt, and can be used with lipstick.

JP 2018-172804 A Japanese Utility Model Laid-Open No. 07-33359

The mask disclosed in Patent Literature 1 described above has face cloths provided only on the top, bottom, left, and right of the mask body, and the central part of the face, the nostrils, and the lips are in direct contact with the mask body. Therefore, it is impossible to avoid the makeup and lipstick on the central part of the face from adhering to the mask body. In addition, the present situation is that a dirty mask must be discarded as it is.

Since the space cover disclosed in Patent Document 2 does not cover the lips, contamination of the mask with lipstick is unavoidable. And, as with the mask disclosed in Patent Document 1, the entire mask with the inside contaminated must be discarded, especially in the current world situation where everyone is required to wear a mask as an antivirus measure The burden on the environment due to disposal cannot be ignored, and has already become a big problem in the field of environmental conservation.
As described above, the prior art has a large problem to be solved as described above.

In addition, the mask is originally used to cover the nostril area and the lip area of the wearer's face. Some wearers wear masks with the nostril area not covered by the mask. In addition, they misunderstood that droplets spread only from the mouth, such as coughs and sneezes, and because wearing a mask itself makes them feel suffocated, they have to move the top of the mask themselves to expose the nostrils. Many wearers wear it in a state where it is easy to breathe.
However, droplets also come out from the nose, and surrounding droplets may be inhaled from the nostrils, which is a very undesirable wearing state from the standpoint of infection prevention.

The object of the present invention is to solve the problems of the prior art and to provide a mask that is used to cover the nostril area and the lip area of the wearer's face. To provide a mask which gives a feeling of use, fits the face naturally without sagging easily, and firmly covers a nostril area, that is, a mask which does not have lipstick and does not sag.

In order to achieve the above object, the present invention is characterized by the configurations listed below. It should be noted that although the constituent elements of the present invention are given the reference numerals used in the examples to be described later, the present invention should not be construed as being limited to the specific configurations indicated by these reference numerals.
Hereinafter, the lipstick-free mask according to the present invention may be simply referred to as "mask".

The present invention is a mask 1 in which ear hooks 2a and 2b are provided on the laterally short sides of a horizontally long rectangular mask body 2 that traverses the wearer's face and covers the nostril region and the lip region,
(1) The mask main body 2 is generally horizontally long and three-dimensionally formed according to the shape of the face. Each upper side part 201c of the right end area G2 has an elastic part 9 having an elastic member that expands and contracts in the longitudinal direction of the mask body 2,
The left and right short sides of the mask body have a width W corresponding to the length L of the left and right short sides 20a and 20b of the mask body 2, and are fixed to the short sides 20a and 20b. The shape of the mask body 2 is such that it is stretched laterally over the nostril region and the lip region of the wearer's face on the inner side 3 of the body 2, and the sanitary sheet 6 is folded back and forth along the upper edge 5c and hung detachably. The sanitary sheet retaining band 5 is three-dimensionally formed so as to fit the .

(2) In addition, the mask main body 2 is a flat surface in which the left and right parts covering the nostril area and the lip area of the wearer's face are individually cut and sewn or joined in a three-dimensional manner at the center so that the central part protrudes outside the mask. It is also possible for the view to present a rectangular shape.
In this case as well, the upper long side of the mask body 2 is horizontally divided into four areas, and the leftmost area G1 and the rightmost area G2 of the four divided areas extend and contract in the longitudinal direction of the mask body 2. having an elastic part 9 with an elastic member,
In addition, inside 3 of the mask body 2, it is three-dimensionally formed so as to fit the shape of the mask body 2 like the mask body 2, and inside the mask body 2, each of the left short side and the right short side is formed. A wide and substantially rectangular sanitary sheet retaining band 5 is provided so as to fix the edge thereof and to form a gap between the mask body 2 and be stretched to form a substantially chord shape.

The elastic part 9 provided in the leftmost area G1 and the rightmost area G2 of the mask main body 2 is such that the dimension of the upper side part 201c before shrinking (pulled and stretched) after shrinking (force The length is 1.1 to 1.25 times the dimension of the upper side portion 201c.

The mask main body 2 according to the present invention is made of any one of woven fabric such as cotton and silk, non-woven fabric, stretchable polyurethane, and nylon. Moreover, these may be combined or mixed.

The sanitary sheet locking band 5 is made of a coarse woven or nonwoven fabric or a mesh fabric, and has liquid permeability between the front and back surfaces of the sanitary sheet 6 hung on the upper side of the sanitary sheet locking band 5. can be anything. The coarseness of the mesh and the size of the mesh depend on its thickness, but it is common sense that a maximum of 1 mm is sufficient. may be

The sanitary sheet 6 is preferably a woven or non-woven fabric of natural fibers or synthetic resin fibers, tissue paper, thin paper or thin cloth impregnated with a disinfectant, a disinfectant, or an aroma agent.

The present invention is not limited to the configurations described above and the configurations described in the embodiments to be described later, and various modifications are possible within the scope of the technical idea of the present invention.

In the lipstick-free mask according to the present invention, the sanitary sheet locking band attached to the inside of the mask body has a width corresponding to the length of the left and right short pieces of the mask body and corresponds to the shape of the mask body. Since the sanitary sheet is three-dimensionally formed, even if the sanitary sheet is hung down, the sanitary sheet retaining band follows the shape of the mask body, so the mouth is not stiff with the sanitary sheet and does not cause discomfort in appearance. .
In addition, since the sanitary sheet retaining band is three-dimensionally formed in the same shape as the mask body, a space is created around the mouth, which reduces the adherence rate of cosmetics such as lipstick and foundation, allowing the mask to be worn comfortably. can be worn.

In addition, the mask body is horizontally divided into approximately four areas, and an elastic member extending and contracting in the longitudinal direction of the mask body is provided on the upper side of the leftmost area and the rightmost area of the four divided areas. Since the mask has stretchable portions, the left and right upper edges of the mask are stretched to form gathers. It can prevent the mask from falling down and exposing the vicinity of the nostrils.
In addition, the gathers formed by the stretchable part loosen the part covering the nostril area and the lip area, widening the space, making it easier to breathe and talk, and significantly reducing stress when wearing the mask. can be done.
The length of the long side before contraction is equal to the length of the long side after contraction in the expansion/contraction part of the upper side of the leftmost area and the rightmost area obtained by dividing the mask body into approximately four parts in the horizontal direction. of 1.1 to 1.25 times, the gathers formed by expansion and contraction are neither too strong nor too weak, they do not unnecessarily swell, and they do not put a burden on the ears and face. Fluffy coverage over the area and the lip area prevents the mask from falling down and the nostrils out of the mask.

Further, in the mask according to the present invention described above, a gap is formed between the mask body, which is substantially horizontally long and has a rectangular shape with short sides left and right, and the mask body, which is open to prepare for wearing on the face and has an arc shape when viewed from above. It is characterized by a configuration in which a wide and substantially rectangular sanitary sheet retaining band is attached to the arc-shaped mask body so as to extend like a chord.
Therefore, since a sufficient gap is secured between the inner side of the mask body and the sanitary sheet locking band, even a wide or thick sanitary sheet can be easily inserted into this wide gap. It is easy to set and remove.
In addition, the stretchable parts provided on the left and right upper sides of the mask body widen the space of the part covering the nostril area and the lip area, so even a thick sanitary sheet can be worn without a feeling of blockage or pressure. .

Thus, the mask according to the present invention can be easily hung by folding the sanitary sheet back and forth along the upper end of the sanitary sheet retaining band, and the sanitary sheet retaining band covers the entire nostril region and lip region. can be covered over By making the sanitary sheet locking band wider, the sanitary sheet locking band itself has a firm stiffness, and the sanitary sheet fits neatly. function can be maintained.
Furthermore, since the sanitary sheet locking band is wide, even if the sanitary sheet is loaded with the upper and lower ends of the sanitary sheet locking band folded back, the upper and lower sides of the sanitary sheet do not overlap the sanitary sheet locking band and the mask body. Since it is held stably between the two, you can wear the mask with confidence without it coming off or slipping.
In addition, since the nostril area and the lip area are four layers, in order from the mouth side, the inside of the folded sanitary sheet (mouth side), the sanitary sheet locking band, the outside of the sanitary sheet, and the mask body, the amount of inhaled droplets The function of a cloth mask, which is said to be less effective than a non-woven mask, can be fully compensated for, and a non-woven mask such as a cloth mask can be used with confidence.

Furthermore, the sanitary sheet retaining band for hanging the sanitary sheet is constructed substantially integrally with the mask body and does not protrude from the outer shape of the mask body. no.
As a result, stains such as cosmetics, runny nose, and food residues adhere to the sanitary sheet, so the mask body can be reused by discarding only the sanitary sheet.

To provide a mask which facilitates breathing of a wearer according to the present invention, avoids discomfort due to dirt on the back side of the mask, and can be repeatedly used cleanly and comfortably by exchanging only the sanitary sheet. can be done.
Furthermore, by promoting the reuse of the mask body, it becomes a green product that can reduce the environmental burden.
In addition, the gathers on the left and right upper sides of the mask catch the mask on the cheekbones and the mask is directed upward, so that the mask does not drop below the nose, and the mask can fully exhibit its functions.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of masks according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an explanatory view of an embodiment of a mask according to the present invention, FIG. 1(a) is a plan view of the inside of the mask, FIG. c) is a plan view of the outside of the mask. FIG. 2 is a side view of the state in which the mask of the embodiment shown in FIG. 1 is folded in two, viewed from the left side. In the figure, 1 is a mask, 2 is a mask main body, 3 is the inside of the mask, 4 is the outside of the mask, 5 is a sanitary sheet locking band, and 6 is a sanitary sheet.

The mask 1 of this embodiment comprises a mask body 2 having a substantially oblong shape that crosses the wearer's face and covers the nostril region and the lip region, and the lateral short sides 20a and 20b of the mask body 2 that are attached to the ears. The mask body 2 is provided with portions 2a and 2b, and the mask body 2 is divided into approximately four parts in the horizontal direction. , there is an elastic part 9 provided with an elastic member that expands and contracts in the longitudinal direction of the mask body 2 .
As shown in FIG. 1(c), when the mask body 2 is divided into approximately four parts in the horizontal direction, AB is the leftmost area G1, BO is the central left area, OC is the central right area, and CD is decomposed into four rightmost areas G2. The leftmost area G1 and the rightmost area G2 indicate positions where the cheekbones of the wearer's face are covered when the mask 1 is worn. Elastic portions 9 are formed on upper side portions 201c of the leftmost area G1 and the rightmost area G2, which are positions covering the cheekbones of the wearer's face.
The expandable part 9 forms a gather, and the pleats of the gather are caught on the cheekbone, and an upward force acts to prevent the mask 1 from slipping down.
In this way, the elastic part 9 prevents the mask 1 from slipping down and exposing the nostrils. Any area corresponding to the position of the cheekbones on the face may be used.
Note that the stretchable portion 9 is such that the size of the upper side portion 201c before shrinking, that is, in a state in which the upward long side portion 20c is stretched by pulling in the longitudinal direction, is greater than the size of the upper side portion 201c after shrinking, that is, in a state in which no force is applied in the longitudinal direction. 1.1 to 1.25 times the size of the portion 201c.

The mask 1 according to the present invention has a substantially rectangular sanitary sheet retaining band 5 on its inner side. The sanitary sheet retaining band 5 has a width W corresponding to the length L of the short sides (the left short side portion 20a and the right short side portion 20b) of the mask body 2, which is generally oblong in shape. The portions 5a and 5b are fixed to the short sides (20a and 20b) of the mask body 1, respectively.
The sanitary sheet locking band 5 has at least the width W of the sanitary sheet locking band 5 where L is the length of the short sides (20a, 20b) of the mask body 2, W<L or "hygienic The width of the seat locking band 5"≈L. That is, the width W of the sanitary sheet locking band 5 is substantially the same as the length L of the short sides 20a and 20b of the mask body 2, or is wide enough to overlap almost the entire mask body 2. The width W is about 85 to 98% of the length L, depending on the size of the mask 1 .
The short sides (5a, 5b) at both ends of the sanitary sheet retaining band 5 are fixed to the left short side 20a and the right short side 20b of the mask body 2, respectively. It is stretched from side to side so as to cover the nostril area and the lip area of the wearer's face.

In the embodiment of the mask 1 according to the present invention shown in FIG. 1, the mask main body 2 is formed by three-dimensionally joining left and right individual members covering the nostril region and the lip region of the wearer's face at the central portion. It has a roughly oblong shape that protrudes upward and downward on each long side.
In this case, the sanitary sheet retaining band 5 is formed by joining left and right separate members three-dimensionally at their central portions in the same manner as the mask body 2 so as to conform to the shape of the mask body 2. is formed three-dimensionally.
The sanitary sheet retaining band 5 fixes the respective edges of the right short side portion 5a and the left short side portion 5b to the left short side portion 20a and the right short side portion 20b on the inner side 3 of the mask body 2. At the same time, it is attached so as to form a gap between it and the mask main body 2 and be stretched to form a substantially chord shape.

The mask body 2 is preferably made of any one of cloth such as cotton and silk, non-woven fabric, elastic polyurethane, and nylon, but the material is not particularly limited as long as it has the same three-dimensional shape.
For example, in another embodiment of the mask according to the present invention shown in FIG. 7, the mask 1x has a mask body 2x made of non-woven fabric or woven fabric, and has wings 200a covering the snout region and wings 200b covering the chin region. It is formed in one piece and provided with metal strips 21x, giving an overall three-dimensional shape.
In the case of such a three-dimensional mask 1x, the sanitary sheet locking band 5x corresponds to the length Lx of the left short side portions 20ax and 20bx of the mask body 2x, and the upper and lower attachment portions 22x and 22x of the ear hook portion 2ax. It has a width Wx that fits between them, and is stretched left and right over the nostril region and the lip region and fixed.
The sanitary sheet retaining band 5x has the same shape as the mask main body 2x, and is configured to stably suspend the sanitary sheet 6x.
Thus, according to the present invention, the material of the mask 1 is not particularly limited, and the sanitary sheet retaining band 5 is formed in the same shape according to the three-dimensional shape of the mask 1 and attached.

The mask 1 according to the present invention holds the sanitary sheet 6 along the upper edge 5c of the sanitary sheet holding band 5. As shown in FIG.
The sanitary sheet 6 is hung along the upper edge 20 of the sanitary sheet retaining belt 5 by folding back and forth. The sanitary sheet 6 hung down can adjust the lower end positions of the front and back sheet parts according to the preference of the wearer and can be easily removed.

The material of the sanitary sheet locking band 5 is not limited as long as it is strong enough to hang the sanitary sheet 6, but if it is made of the same material as the mask body 2, there is no discomfort even when the sanitary sheet 6 is not hung. Can be worn.
On the other hand, if the sanitary sheet locking band 5 is made of a coarse woven/nonwoven fabric or a mesh woven fabric, the sanitary sheet 6 suspended from the upper edge 5c of the sanitary sheet locking band 5 may cause a runny nose. etc. can move from the sanitary sheet portion on the side of the nostrils to the sanitary sheet portion inside the main body, the liquid permeability is high, and the effect of the sanitary sheet 6 can be further enhanced.

In this case, the coarseness and size of the mesh of the sanitary sheet locking band 5 depends on its thickness. It may be set to several mm or more as long as it does not affect the
The material of the sanitary sheet locking band 5 can be appropriately selected depending on the application and effect.

In the mask 1 of the present invention, the sanitary sheet retaining band 5 is also three-dimensionally formed in the same manner as the mask main body 2, so that there is a spatial margin between the inside of the mask main body 2 and the wearer's nostrils and lips. The degree can be given, and even if the sanitary sheet 6 is hung down, it can be worn comfortably without feeling stuffy.

The sanitary sheet 6 is a woven fabric/non-woven fabric of natural fibers or synthetic resin fibers, tissue paper, thin paper or thin fabric impregnated with a disinfectant/sterilizer or aroma agent, or non-woven fabric. In addition, it can be selected and used according to arbitrary uses and effects.

According to this embodiment, it is possible to provide a clean and comfortable mask that can be used repeatedly by replacing only the sanitary sheet 6 to avoid discomfort due to dirt on the back side of the mask.
In addition, by forming the sanitary sheet retaining band 5 three-dimensionally, the space between the mask main body 2 and the wearer's nostril region or lip region can be expanded, thereby facilitating breathing.
Furthermore, by promoting the reuse of the mask body 2, it becomes a green product that can reduce the environmental load.

Below, the mask 1 according to the present invention will be described in detail.
FIG. 3 is a schematic view of the sanitary sheet locking band provided inside the mask body as seen from the left side, and FIG. 4 is a nostril region bulge and a lip region bulge of the mask shown in FIG. FIG. 5 is a schematic diagram showing the arrangement of the nostril region bulging portion and the lip region bulging portion shown in FIG. 4 as viewed from the left side, and FIG. FIG. 6 is a schematic view of the mask shown in FIG. 5 cut in the left-right direction at a position one-third from the top of the mask shown in FIG. 5 in an open state;

As shown in FIG. 1, the mask 1 according to the present invention covers the wearer's face under the eyes including the nostril region bulging portion 10 and the lip region bulging portion 11 (see FIG. 3) in the laterally unfolded state at the time of preparation for wearing. Central portions (20e, 20f) of the upper long side portion 20c and the lower long side portion 20d extending to the left and right of the wearer's face form a substantially rectangular shape that protrudes slightly outward. This overhang corresponds to the shape of the ridge of the bridge of the nose and the chin, which is the most protruding part of the face, and the shape of the mask body 2 is basically horizontally long.

When the mask 1 is opened to the left and right (left and right with respect to the wearer's face: lateral direction, hereinafter the same) in preparation for wearing the mask 1 on the wearer's face, A substantially rectangular mask body 2 that bulges upward and downward with respect to a person's face: vertical direction; It comprises parts 2a and 2b.
In the mask 1, the mask main body 2 is horizontally divided into four areas, and elastic members that extend and contract in the longitudinal direction of the mask main body 2 are provided on the upper side portions 201c of the leftmost area G1 and the rightmost area G2 of the four divided areas. The mask body 2 expands and contracts on the left and right sides of the mask body 2 to form gathers.
The gathers catch on the bulges of the cheekbones under the wearer's eyes to enclose them, and a force is generated in the entire mask to rise upward, thereby preventing the mask 1 from slipping down and exposing the vicinity of the nostrils.

FIG. 8 is an explanatory diagram for explaining the effect of the expansion/contraction portion of the mask according to the present invention. The upper side portions 201c of the leftmost area G1 and the rightmost area G2 covering the cheekbones H are provided with an elastic portion 9 having an elastic member that expands and contracts in the longitudinal direction of the mask body 2, and the upper side portions 201c are formed with gathers. is shown.
The gathers formed with the expandable portions 9 cover the cheekbones H under the left and right eyes, and the mask 1 is worn so as to be caught by the cheekbones H. The contraction of the gathers exerts a force that tends to lift the entire mask 1 upward. It does not slide down beyond the cheekbones H and prevents the nose J from being exposed from the mask 1.例文帳に追加

In addition, the mask body 2 uses a larger amount of fabric than when the elastic part 9 does not have gathers, and the fine folds formed by the gathers form a large space in the part covering the nostril area and the lip area, allowing breathing and conversation. It is easy to do.
The stretchable part 9 is formed by marking the mask main body 2 and one string-like elastic member (rubber string), and attaching the string-like elastic member (rubber string) to the upper long side 20c of the mask main body 2. When sewing the leftmost area G1 and the rightmost area G2 where you want to form a gather, pull and stretch the elastic member to sew, and in the other center left and right areas N1 and N2, stretch the elastic member. It can be easily formed by sewing without pulling.
When manufactured in this manner, gathers are not formed in the upper side portions of the central left and right areas N1 and N2, but the elastic members that are not stretched are sewn in as they are, and the elastic members are used as core materials in the upper side portions of the central left and right areas N1 and N2. , and the strength of the upward long side portion 20c is increased. Further, since it is composed of a single elastic member, there is no dropout, and the effect as a core material can be further exhibited.
As described above, the mask 1 according to the present invention has a firm upward long side 20c, so that the mask body 2 can be stably worn even if silk fabric or thin cotton fabric is used as the fabric of the mask body 2. can do.

The stretchable portion 9 is such that the dimension of the upward long side portion 20c before contraction, that is, in a state in which there is no expansion and contraction by the elastic member, that is, in a state in which the stretchable portion 9 is stretched in the longitudinal direction is 1.1 to 1.25 times as large as the dimension of .
If the stretch rate is lower than this, the formation of gathers is small, and it slides down without getting caught on the cheekbones. On the other hand, if the expansion/contraction rate is higher than this, the gathers formed by expansion/contraction are too close to each other, the unevenness of the gathers becomes large, and a large number of gaps are formed between the upward long side portion 20c and the face, impairing the function of the mask. . By setting it to about 1.1 to 1.25 times above, the gathers formed by expansion and contraction are not too strong or too weak, and the nostril area and the lip area are softly covered without putting a burden on the ears and face. , the mask can be lowered and the nostrils can be prevented from coming out of the mask.
Furthermore, the gathers formed by the elastic part 9 due to the expansion and contraction according to the above numerical values widen the space of the part covering the nostril area and the lip area, making it easier to breathe and talk, and the maximum stress when wearing the mask. Greatly reduces breathlessness.

In the mask 1 according to the present invention, on the wearer's face side (inner side) of the mask body 2, the left short side portion 20a and the right short side portion 20b of the mask body 2 are each provided with the right side of the sanitary sheet locking band 5. Edges of the short side portion 5a and the left short side portion 5b are fixed.
The sanitary sheet retaining band 5 is inserted between the mask main body 2 and the mask body 2 with a gap therebetween, and is attached so as to have a substantially chordal shape when viewed from above (FIG. 1(b)).
The sanitary sheet retaining band 5 is wide and has a rectangular shape with a central portion protruding forward like the mask body 2 . The sanitary sheet retaining band 5 does not have an elastic portion so that the sanitary sheet 6 can be hung neatly and stably without unnecessary fabric.

The lower end of the mask body 2 is receded from the straight line YY passing through the upper end of the mask body 1 perpendicular to the straight line passing through the left-right center of the mask 1 toward the lower jaw of the wearer by a distance d (see FIG. 3). .
This dimension d is set to the extent that it hangs over the lower end of the chin and prevents the mask body from slipping upwards on the face. The dimension d may be arbitrarily set according to the mask size (for children, adults, women, men, or S, M, L, LL, etc.).

In this embodiment, as shown in FIGS. 5 and 6, the mask main body 2 consists of left and right individual members that cover the nostril region bulging portion 10 and the lip region bulging portion 11 of the wearer's face sewn together at the center. Alternatively, it has a joined central connecting line 2g. The left and right individual members are made of woven fabric, non-woven fabric, elastic polyurethane, nylon, plastic sponge material, or the like.
The center connection line 2g is formed by three-dimensionally stitching or joining a portion covering the nostril region bulging portion 10 and a portion of the lip region bulging portion 11. As shown in FIG.
In the present embodiment, the mask 1 is described as two separate members stitched together or joined at the center. The material may be three-dimensionally molded into the nostril region bulging portion 10 and the lip region bulging portion 11 during cold press punching. Moreover, in the case of a woven fabric or a non-woven fabric, it may be three-dimensionally formed by forming a tuck.

In this embodiment, since it is assumed that the mask body 2 is made of woven fabric of natural fibers or synthetic fibers, a mask having seams for preventing fraying of cut edges is taken as an example. Therefore, there are seams 2e and 2f on the upper and lower edges.
As a matter of course, the seams 2e and 2f are slightly recessed inward from the outer edge of the mask body 2. As shown in FIG. The elastic member forming the stretchable portion 9 may be sewn in using this seam 2e.
A three-dimensional space (space) between the mask main body 2 and the sanitary sheet locking band 5 in the nostril area swelling part 10 is larger than that of the lip area swelling part 11 . As a result, the discharge pressure during exhalation and the inhalation pressure during inspiration are reduced, making breathing easier.

In the drawing shown in FIG. 4, reference numerals 2h and 2i, 2j and 2k denote marginal fabric portions for forming the nostril region bulging portion 10 and the lip region bulging portion 11, respectively. The nostril region bulging portion 10 is located within the upper one-third range D1 obtained by dividing the maximum length L of the mask body 2 into three, and the lip region bulging portion 11 is located within the lower one-third range D2. (See Figure 5).
The lip region bulging portion 11 facilitates the movement of the lips during conversation, suppresses slurring of spoken words, and enables clear speech.
The middle one-third range D3 is a transition curve area for connecting the arcs forming the nostril area bulge 10 and the lip area bulge 11 .

In addition, the sanitary sheet locking band 5 is similarly provided with a nostril region bulging portion 10a and a lip region bulging portion 11a so as to match the nostril region bulging portion 10 and the lip region bulging portion 11 formed on the mask body 2. is formed.
Then, the sanitary sheet 6 is folded back and forth along the upper edge 5c of the sanitary sheet locking band 5, and the mask main body 2 and the sanitary sheet locking band 5 are separated so that they can be hung down easily and stably to the required position. A gap is formed between
XX shown in FIGS. 3 to 6 indicates a horizontal straight line perpendicular to the straight line YY passing through the upper and lower ends of the mask body 2 .
The sanitary sheet 6 is not only hung on the sanitary sheet retaining band 5, but also folded up and down at the upper and lower ends of the sanitary sheet retaining band 5 so that the upper and lower sides of the sanitary sheet 6 are attached to the sanitary sheet. It can also be arranged so as to be inserted between the locking band 5 and the mask body 2 to hold it down.

FIG. 9 is a cross-sectional view showing an example of how the mask according to the present invention is used.
In the example shown in FIG. 9( a ), the sanitary sheet 6 is folded back and attached along the upper edge 5 c of the sanitary sheet locking band 5 to the front and back sides.
On the other hand, in the example shown in FIG. 9B, the upper and lower sides of the sanitary sheet 6 are folded back at the upper edge 5c and the lower edge 5d of the sanitary sheet engaging band 5, and the upper and lower sides 60, 60 of the sanitary sheet 6 are engaged with the sanitary sheet. It is arranged so as to be inserted between the bandage 5 and the mask body 2 and held down.
For example, when tissue paper is used as the sanitary sheet 6, the material itself is not stiff and is weak against moisture, so the tissue paper may be displaced, distorted, and curled up after being used for a long time.
In such a case, when hanging the sanitary sheet 6 on the sanitary sheet locking band 5, the tissue paper is first folded in two and brought into contact with the sanitary sheet locking band 5 from the center so that the sanitary sheet locking band 5 is folded. The upper and lower portions exceeding the width of the mask are folded and sandwiched between the sanitary sheet locking band 5 and the mask body 2.例文帳に追加
As a result, the upper and lower portions of the tissue paper are sandwiched between the sanitary sheet locking band 5 and the mask body 2, which makes it more stable and less likely to come off and less likely to become crumpled.

In addition, in the case of the sanitary sheet 6 made of cotton, the size varies depending on the product. can be folded and sandwiched between the mask main body 2 side, more diverse usage becomes possible.
When the tissue paper is used as the sanitary sheet 6 and the antibacterial effect is desired to be enhanced in a hospital or elderly facility, one tissue paper is sandwiched between the sanitary sheet locking belts 5 at the top and bottom, and another tissue paper is stacked. If the sanitary sheet 6 is doubled, a higher antibacterial action can be exhibited.
This is possible because the sanitary sheet locking band 5 is widened and its left and right sides are firmly fixed to the mask body 2, so that the thickness and weight of the sanitary sheet 6 can be sufficiently endured.

As shown in FIGS. 1 and 3, the width W along the edges of the left short side portion 5a and the right short side portion 5b of the sanitary sheet locking band 5 is equal to the left short side portion 20a and the right short side of the mask body 2. It is slightly narrower than the length L along the edge of the portion 20b. The width W is preferably narrower than the length L by about 85 to 98%. As shown in FIG. 7, in the case of a mask of the type in which the ear hooks 2a and 2b are thermocompression bonded to the mask main body 2, the width W is formed so as to fit between the ear hooks 2a and 2b.
As a result, the sanitary sheet 6 hung on the sanitary sheet locking band 5 does not protrude from the mask body 2 and is formed wide, so that the sanitary sheet locking band 5 is hard to twist and does not feel stiff around the mouth. The hygienic sheet 6 can be stably hung without causing a sense of incongruity in appearance.
That is, the mask 1 according to the present invention has a sanitary sheet locking band 5 having a width W corresponding to the length L of the left and right short pieces of the mask body 2 . It should be understood that a sanitary sheet retaining band 5 is provided with a width W such that it is arranged in a retracted position.

4 and 5, where R1 is the radius of curvature of the nostril region bulging portion 10 along the central connection line 2g, and R2 is the radius of curvature of the lip region bulging portion 11, R1>R2. The protruding portion 10 and the lip area protruding portion 11 are connected by a relaxation curve (for example, a clothoid curve, etc.). As a result, the nostril region bulging portion 10 and the lip region bulging portion 11 have a natural continuous shape, and the occurrence of wrinkles and folds is alleviated.

The mask 1 according to the present invention is in an unfolded state when worn to cover the nostril region bulging portion 10 and the lip region bulging portion 11 of the wearer's face, and is positioned upward 3 along the central connection line 2g of the mask body 2. The nostril region bulging portion 10 is located in one-third (D1), and the lip region bulging portion 11 is located in the lower one-third (D2) along the central connecting line 2g.

FIG. 6 is a schematic diagram showing a state in which the mask is opened to the left and right in preparation for wearing on the face, cut in the left and right direction (X--X) at a position one-third from the top.
In FIG. 6, when the average curvature radius 7 of the curved portion in the nostril area 10 in the Z-Z direction is R3, and the average curvature radius 8 in the Z-Z direction of the sanitary sheet locking band 5 is R4, R3 <R4. A straight line Z--Z indicates a straight line perpendicular to the straight lines X--X and Y--Y (in the front-rear direction with respect to the face).

By setting R3<R4, for example, even when the mask body 2 is pulled in the X-X direction (horizontal direction) and the curvature radius R4 of the sanitary sheet locking band 5 is set to infinity (∞), the mask body 2 remains in place. The radius of curvature R3 is finite, and the space between them never disappears.
As a result, the sanitary sheet 6 can be easily folded over the sanitary sheet locking band 5, and the sanitary sheet 6 can be easily set so as to sufficiently cover the nostril area swelling part 10 and the lip area swelling part 11. - 特許庁. In addition, the space for breathing formed between the mask main body 2 and the sanitary sheet locking band 5 can be made sufficient, and a space is also formed in the sanitary sheet locking band 5, the sanitary sheet 6 to be hung, and the mouth. and breathe easier.

In this embodiment, the material of the mask body 2 is preferably a woven fabric, and the left short side portion 20a and the right short side portion 20b of the mask body 2 are portions that are continuous with the fabric of the mask body 2. It is preferable to use either the same cloth as the mask main body 2 or scraps of other cloth different from the mask main body 2 .

The sanitary sheet retaining band 5 can be made of the same material as that of the mask body 2, or any other material that is strong enough to hang the sanitary sheet 6, such as coarse woven/nonwoven fabric, mesh woven fabric, or the like.

In addition, the sanitary sheet 6 is appropriately selected from washable and reusable cotton cloth, sanitary non-woven fabric, tissue paper, tissue paper impregnated with disinfectant/sterilizer or aroma agent, and paper and fabric such as filters. can do.
As a result, the load on the environment can be reduced, and the mask main body 2 can be reused, thereby forming a green product.

According to the mask according to the present invention described above, the gap (breathing space) between the inner side of the arc-shaped mask body 2 and the string-shaped sanitary sheet locking band 5 is sufficiently secured, and the wide gap is widened. The sanitary sheet 6 can be easily loaded and set.
In addition, since the sanitary sheet retaining band 5 is formed in a three-dimensional shape corresponding to the mask main body 2, a space around the nostrils and the mouth is secured, and breathing is easy when worn, and the appearance does not look strange. Become.

Since the sanitary sheet 6 can be folded back and forth along the upper edge 5c of the sanitary sheet retaining band 5 and hung down easily, the sanitary sheet 6 sufficiently covers the nostril region and the lip region. can do. As a result, cosmetics such as lipstick and foundation and stains such as runny nose adhere to the sanitary sheet 6, so that the mask body 2 can be used repeatedly by discarding only the sanitary sheet 6. - 特許庁

Furthermore, since the sanitary sheet locking band 5 is wide as described above, the sanitary sheet locking band 5 itself is firmly fixed to the mask body 2, and even if the sanitary sheet 6 is hung down, it is effective and stable. Thus, it is prevented from twisting or sticking out in the mask body 2. - 特許庁
In addition, since the sanitary sheet locking band 5 is three-dimensionally formed like the mask body 2, it is pushed out by the bridge of the nose when the mask is worn, and the center portion of the sanitary sheet retaining band 5 protrudes outward like the mask body 2. shape. As a result, there is no sense of incongruity or resistance when wearing.

As described above, according to the mask of the present invention, the mask does not slip off when worn and the nose is exposed, and the wearer's breathing becomes easier.
