However, even with the mask of Patent Document 1, the adhesion between the mask and the face is still low, and the invasion of viruses, bacteria, dust, etc. cannot be sufficiently prevented, and there is room for improvement.

An object of the present invention is to provide a mask having high adhesion to the face.

The mask according to the first aspect of the present invention has a first end edge and a second end edge facing the first end edge, and covers at least a part of the user's face, and the mask body of the mask body. It includes a first cloth and a second cloth that are arranged inside and come into contact with the face. The first cloth is arranged on the first end side side of the second cloth, and the second cloth is arranged on the second end side side of the first cloth. The first cloth and the second cloth partially overlap each other, and are developed so that the area where the mask body overlaps with each other becomes smaller when the mask body is attached to the face.

The mask according to the second aspect of the present invention is the mask according to the first aspect, the first end side is an upper side, and the second end side is a lower side.

The mask according to the third aspect of the present invention is the mask according to the second aspect, and the second cloth has a lower portion, a left end portion and a right end portion. The lower portion is fixed to one or more fixed points near the center in the left-right direction of the mask body, between the one or more fixed points and the left end portion, and between the one or more fixed points and the right end portion. It is not fixed to the mask body between the two.

The mask according to the fourth aspect of the present invention is a mask according to any one of the first to third aspects, and at least one of the first cloth and the second cloth is impregnated with a beauty ingredient. ..

The mask according to the fifth aspect of the present invention is a mask according to any one of the first to fourth aspects, and the first cloth and the second cloth are unfolded when the mask body is attached to the face. When this is done, a gap is formed between the first cloth and the second cloth to accommodate at least one of the user's mouth and nose.

According to the above viewpoint, the first cloth and the second cloth that come into contact with the face are arranged inside the mask body. The first cloth is arranged on the first end side side of the mask body with respect to the second cloth, and the second cloth is arranged on the second end side side of the mask body facing the first end side with respect to the first cloth. To. The first cloth and the second cloth partially overlap each other, and when the mask body is attached to the face, they are developed so that the area where they overlap is small. Therefore, when the mask body is attached to the face, the contact area between the first cloth and the second cloth and the face increases. Therefore, the adhesion between the mask and the face is enhanced.

The mask body 30 is a cloth that covers at least a part of the face, and in the present embodiment, mainly covers the mouth and nose. The first cloth 10 and the second cloth 20 are sandwiched between the face and the mask body 30 when the mask 1 is attached to the face, come into contact with the face, and play a role of enhancing the adhesion between the mask 1 and the face. Further, the mask 1 has an ear hook portion 40 connected to the mask main body 30. The ear hook 40 is hooked on the left and right ears of the user when the mask 1 is attached to the face, whereby the mask body 30, the first cloth 10 and the second cloth 20 are in the area around the mouth and nose on the face. The state of covering is maintained.

The mask body 30 is a sheet-like member, and is composed of a breathable sheet material such as a non-woven fabric or a woven cloth. The sheet material referred to here can preferably be composed of a non-woven fabric formed by a spunbond method, a melt blow method, a thermal bond method, a spunlace method or the like, and from the viewpoint of shape retention, particularly by the spunbond method. It is more preferable to be composed of the formed non-woven fabric. Further, as the fiber material constituting the sheet material referred to here, for example, synthetic fibers such as polypropylene, polyethylene and polyester can be selected, and natural fibers such as paper, rayon and cotton can be selected. The mask main body 30 may have a single-layer structure composed of one sheet material, or may have a multi-layer structure composed of two, three or more sheet materials stacked on top of each other. .. The mask body 30 includes, for example, an S layer (single layer of spunbond), an SS layer (two-layer structure of spunbond-spanbond), an SSS layer (three-layer structure of spunbond-spanbond-spanbond), and an SMS layer. (Three-layer structure of spunbond-melt blow-spanbond) and the like.

The first cloth 10 and the second cloth 20 of the present embodiment are impregnated with a drug, and the drug contains a beauty ingredient having a beauty effect on the skin. Therefore, when the first cloth 10 and the second cloth 20 come into contact with the face when the mask 1 is worn on the face, a drug containing a beauty ingredient is applied to the face. The beauty ingredient referred to here is a moisturizing ingredient in the present embodiment, and the drug includes a preservative and water in addition to the moisturizing ingredient. Examples of the moisturizing component include glycerin, collagen, hyaluronic acid, ceramide, and squalane, but glycerin and hyaluronic acid are particularly preferable from the viewpoint of impregnating cloth 10 and cloth 20 to exert a moisturizing effect. When the mask 1 is used in the daytime, the ratio of the beauty component contained in the drug is preferably 5 to 30% by weight. Examples of preservatives include propynyl butylcarbamate iodide, methyl paraoxybenzoate, propyl paraoxybenzoate, phenoxyethanol and the like, but from the viewpoint of exhibiting resistance to mold bacteria, iodide butylcarbamate in particular. Propinyl is preferred. The cosmetological ingredients include whitening agents (vitamin C derivatives, hydroquinone, arbutin, etc.), astringent agents (citric acid, alum, ethanol, etc.), skin protectants, and skin nutrients in place of or in addition to the above-mentioned moisturizing ingredients. It may contain one or more elements selected from the group containing.

The first cloth 10 and the second cloth 20 are also sheet-like members, and are composed of a breathable sheet material such as a non-woven fabric or a woven cloth. The sheet material referred to here can also be preferably composed of a non-woven fabric formed by a spunbond method, a melt blow method, a thermal bond method, a spunlace method or the like, and from the viewpoint of retaining chemicals, particularly by the spunlace method. It is more preferable to be composed of the formed non-woven fabric. Further, as the fiber material constituting the sheet material referred to here, for example, synthetic fibers such as polypropylene, polyethylene and polyester can be selected, and natural fibers such as paper, rayon and cotton can also be selected. The first cloth 10 and the second cloth 20 may each have a single-layer structure made of one sheet material, or may be formed by stacking two, three, or more sheet materials. It may have a multi-layer structure.

The mask body 30 is configured to be three-dimensionally deployable. More specifically, as shown in FIGS. 3 to 5, the mask body 30 has one or a plurality of pleats 31 extending in the left-right direction. Then, as shown in FIGS. 5 and 6, when the mask main body 30 is pulled in the vertical direction and the pleats 31 are expanded in the vertical direction, the mask main body 30 extends in the vertical direction. At this time, the central portion of the mask body 30 mainly in the left-right direction extends in the vertical direction. As a result, the mask body 30 can cover a wider area of the face. As shown in FIG. 5, the pleats 31 are folded before their unfolding, and at this time, the mask body 30 is flat as a whole. On the other hand, as shown in FIG. 6, after the pleats 31 are unfolded, the mask body 30 expands in a dome shape. In other words, it not only spreads in the vertical direction, but also spreads forward so that the central portion in the vertical direction protrudes, and is developed three-dimensionally. In FIG. 5, the mask 1 is drawn relatively three-dimensionally in the front-rear direction for the sake of clarity, but it is actually more flat.

The mask main body 30 has an upper side L1, a lower side L2 facing the upper side L1, a left side L3, and a right side L4 facing the left side L3, and has a substantially rectangular shape as a whole before unfolding. As shown in FIG. 1, both the first cloth 10 and the second cloth 20 extend in the left-right direction from the left side L3 to the right side L4 of the mask main body 30. Further, the first cloth 10 extends in the vertical direction from the upper side L1 to the vicinity of the center line in the vertical direction of the mask main body 30. That is, the first cloth 10 covers substantially the upper half of the mask body 30, and has a substantially rectangular shape as a whole. On the other hand, the second cloth 20 extends in the vertical direction from slightly above the center line in the vertical direction of the mask body 30 to slightly above the lower side L2. The second cloth 20 also has a substantially rectangular shape as a whole.

As described above, the first cloth 10 is arranged on the upper side L1 side of the second cloth 20, and the second cloth 20 is arranged on the lower side L2 side of the first cloth 10. The first cloth 10 and the second cloth 20 are partially overlapped in the vertical direction, and the second cloth 20 is arranged on the rear side (closer to the face and farther from the mask body 30). In FIG. 1, the lower side of the first cloth 10, which is originally invisible due to the presence of the second cloth 20, is illustrated by a alternate long and short dash line for reference.

The upper side, the left side, and the right side forming the outer peripheral edge of the first cloth 10 overlap each other with the upper side L1, the left side L3, and the right side L4 forming the outer peripheral edge of the mask main body 30. Further, the first cloth 10 is fixed to the mask main body 30 along the entire widths of the upper side, the left side and the right side thereof. Lines C1 shown in FIGS. 1 to 4 indicate fixing points between the

cloths

10 and 20 and the mask body 30. On the other hand, the first cloth 10 is not fixed to the mask body 30 along the lower side thereof. Therefore, the first cloth 10 is formed in the shape of a bag with an empty lower portion together with the mask body 30 facing the first cloth 10.

The left side and the right side forming the outer peripheral edge of the second cloth 20 overlap with the left side L3 and the right side L4 forming the outer peripheral edge of the mask main body 30, respectively. Further, the second cloth 20 is fixed to the mask main body 30 along the entire widths of the left side and the right side thereof (see line C1 in FIGS. 1 and 2). On the other hand, the second cloth 20 is not fixed to the mask main body 30 along the upper side thereof, and is fixed to one or more fixed points P1 of the mask main body 30 along the lower side thereof.

More specifically, the second cloth 20 has a lower portion 20D, a left end portion 20L, and a right end portion 20R extending along the lower side, the left side, and the right side, respectively. In this embodiment, the lower portion 20D is fixed at the mask main body 30 and four fixing points P1. Two of these fixed points P1 are arranged in the vicinity of the left and right sides of the mask main body 30 with the center in the left-right direction interposed therebetween. The lower part 20D is not fixed between the two inner fixed points P1 and P1, and is not fixed between the leftmost fixed point P1 and the leftmost fixed point 20L, and is not fixed between the leftmost fixed point P1 and the leftmost fixed point 20L. It is not fixed between P1 and the right end 20R.

The method of fixing the

cloths

10 and 20 and the mask body 30 can be appropriately selected. For example, methods such as heat fusion (including ultrasonic fusion) and sewing can be adopted. In the present embodiment, heat fusion is performed in a broken line shape along the line C1 shown in FIGS. 1 to 4.

As described above, the mask body 30 is three-dimensionally deployed when it is attached to the face. At this time, as shown in FIGS. 2 and 6, the first cloth 10 and the second cloth 20 are also three-dimensionally developed, and the lower part of the first cloth 10 and the upper part of the second cloth 20 project slightly forward. As a result, the

cloths

10 and 20 can come into close contact with parts having a three-dimensional structure on the face, such as the tip of the nose and the base of the mouth. In addition, the

cloths

10 and 20 can come into close contact with relatively flat parts of the face, such as the areas surrounding the cheeks, the left and right sides of the mouth, and the lower part.

When the mask body 30 is unfolded, the first cloth 10 and the second cloth 20 are unfolded so that the area where they overlap is small. Therefore, when the mask body 30 is attached to the face, the contact area between the first cloth 10 and the second cloth 20 and the face is increased, and the adhesion between the mask 1 and the face is enhanced. Therefore, the mask 1 can efficiently prevent the invasion of viruses, bacteria, dust, etc. into the mouth, nose, and the like. Further, in the present embodiment, due to such high adhesion, the beauty component impregnated in the cloth 10 and the cloth 20 can be efficiently applied to the face.

As described above, the first cloth 10 is not fixed to the mask body 30 along the lower side thereof, and the second cloth 20 is not fixed to the mask body 30 along the upper side thereof. Therefore, the lower part of the first cloth 10 and the upper part of the second cloth 20 follow the bulge of the mask body 30 and are not pulled excessively forward. Similarly, the lower part of the second cloth 20 is not fixed to the mask body 30 except for the fixing point P1. Therefore, the lower portion of the second cloth 20 is not pulled excessively forward by following the bulge of the mask main body 30 except in the vicinity of the center in the left-right direction in which the fixed point P1 is arranged. Therefore, the first cloth 10 and the second cloth 20 can fit the face exactly.

Further, when the mask main body 30 is unfolded, a gap S1 is formed between the first cloth 10 and the second cloth 20 mainly in the central portion in the left-right direction of the mask main body 30 (see FIGS. 2 and 6). .. This gap S1 can mainly accommodate the user's mouth and nose. Therefore, when the user wears the mask 1, the first cloth 10 and the second cloth 20 come into close contact with the user's face, but the user can breathe comfortably.

Before unfolding the mask 1, the vertical length of the first cloth 10 is R1, the vertical length of the second cloth 20 is R2, and the upper and lower parts of the overlapping portion of the first cloth 10 and the second cloth 20 are above and below. Let the length in the direction be R3. At this time, from the viewpoint of sufficiently securing the contact area between the

cloths

10 and 20 and the face, it is preferable that R3 / R1 ≧ 0.1, more preferably R3 / R1 ≧ 0.2, and R3. It is more preferable that / R1 ≧ 0.3. From the same viewpoint, R3 / R2 ≧ 0.1 is preferable, R3 / R2 ≧ 0.2 is more preferable, and R3 / R2 ≧ 0.3 is further preferable. From the same viewpoint, R3 ≧ 0.5 cm is preferable, R3 ≧ 1.0 cm is more preferable, and R3 ≧ 1.5 cm is further preferable.

From the viewpoint of sufficiently securing the gap S1 for accommodating the nose and mouth, R3 / R1 ≦ 0.8 is preferable, R3 / R1 ≦ 0.7 is more preferable, and R3 / R1 ≦ 0. It is more preferably 6. From the same viewpoint, R3 / R2 ≦ 0.8 is preferable, R3 / R2 ≦ 0.7 is more preferable, and R3 / R2 ≦ 0.6 is even more preferable. From the same viewpoint, R3 ≦ 4.0 cm is preferable, R3 ≦ 3.5 cm is more preferable, R3 ≦ 3.0 cm is more preferable, and R3 ≦ 2.5 cm is preferable. More preferred.

The ear hook portion 40 has a pair of left and

right string members

41 and 42. Both ends of the left end of the string member 41 are fixed to the vicinity of the upper end and the lower end of the left end of the mask body 30, respectively, and the string member 41 forms a closed loop together with the left end of the mask body 30. Similarly, both ends of the right end of the string member 42 are fixed near the upper end and the lower end of the right end of the mask body 30, respectively, and the string member 42 forms a closed loop together with the right end of the mask body 30. As a result, the

string members

41 and 42 can be hooked on the left and right ears, respectively. The method of fixing the

string members

41 and 42 to the mask body 30 is not particularly limited, and for example, a method such as heat fusion (including ultrasonic fusion) or sewing can be adopted.

From the viewpoint of enabling the

string members

41 and 42 to be firmly hooked on the ears regardless of the size of the user's face, the

string members

41 and 42 may have elasticity along the longitudinal direction thereof. preferable. The materials constituting the

string members

41 and 42 are not particularly limited, but for example, polyester or the like can be used.

A linear nose piece 50 is fixed to the mask body 30 along its upper side L1. The nose piece 50 can be easily bent and is made of a plastically deformable material, for example, a plastic resin, a metal, or the like. The nose piece 50 is bent along the shape of the nose when the user wears the mask 1, and serves to reduce the gap between the mask 1 and the nose. By the way, as shown in FIGS. 5 and 6, in the present embodiment, the mask main body 30 is folded forward along the upper side L1 and the lower side L2, and is doubly overlapped in the upper part and the lower part. The nose piece 50 is embedded between the doubly stacked portions at the top of the mask body 30. Therefore, originally, the nose piece 50 cannot be visually recognized in FIGS. 1 to 4, but its position is shown by a chain line for reference. Further, in the present embodiment, the mask 1 is heat-sealed (may be sewn or the like) so as to surround the nose piece 50 so that the nose piece 50 does not fall off from the mask body 30 (FIGS. 1 to 1 to 1). See line C1 in FIG. 4).
