Accordingly, the adhesion between the mask and the face can be improved.

The form used to implement the invention

Hereinafter, a face mask according to an embodiment of the present invention will be described with reference to the drawings.

<1. The first embodiment> Figs. 1 and 2 show a view of the mask 1 of this embodiment viewed from the inside, and Figs. 3 and 4 show a view of the mask 1 viewed from the outside. The mask 1 will be three-dimensionally unfolded when worn on the face of the user. Figures 1 and 3 show the mask 1 before unfolding, and Figures 2 and 4 show the mask 1 after unfolding. Fig. 5 is a cross-sectional view taken along the line V-V in Fig. 1, and Fig. 6 is a cross-sectional view taken along the line VI-VI in Fig. 2. In addition, in the following description, up and down, left and right, and front and rear are defined as shown in FIGS. 1 to 6 based on the state in which a standing user wears the mask 1.

As shown in FIGS. 1 to 6, the mask 1 includes: a mask body 30; and two pieces of cloth 10 and 20, which are arranged to overlap the mask body 30 on the inner side of the mask body 30. Hereinafter, the cloths 10 and 20 are distinguished, and 10 may be referred to as the first cloth, and 20 may be referred to as the second cloth. The mask body 30 is a cloth covering at least a part of the face, and in this embodiment, it mainly covers the mouth and nose. When the mask 1 is worn on the face, the first cloth 10 and the second cloth 20 are sandwiched between the face and the mask body 30, and contact the face to improve the adhesion between the face mask 1 and the face. In addition, the mask 1 has ear straps 40 connected to the mask body 30. The ear-hanging portion 40 is hooked to the left and right ears of the user when the mask 1 is worn on the face, thereby maintaining the mask body 30, the first cloth 10, and the second cloth 20 covering the mouth and nose area in the face. state.

The mask body 30 is a sheet-shaped member, and is composed of a non-woven fabric or a woven fabric having air permeability. The so-called sheet here can preferably be made by spunbond method, melt blown method, thermal bond method, or spunlace method. From the standpoint of shape stability, it is particularly preferable to use a non-woven fabric formed by a spunbond method. In addition, as the fiber material constituting the sheet referred to herein, 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. In addition, the mask body 30 may have a single-layer structure composed of one sheet, or may have a multilayer structure composed of two, three, or more sheets stacked. The mask body 30 can be composed of, for example, S layer (spunbond single layer), SS layer (spunbond-spunbond two-layer structure), SSS layer (spunbond-spunbond-spunbond three-layer structure), SMS layer ( Spunbond-meltblown-spunbond three-layer structure) and so on.

The first cloth 10 and the second cloth 20 of the present embodiment are impregnated with a medicine, and the medicine contains a cosmetic ingredient having a cosmetic effect on the skin. Therefore, when the mask 1 is worn on the face, when the first cloth 10 and the second cloth 20 contact the face, a drug containing a cosmetic ingredient is applied to the face. The beauty ingredient referred to here is a moisturizing ingredient in this embodiment, and in addition to the moisturizing ingredient, the medicine also contains an antiseptic and water. Examples of moisturizing ingredients include glycerin, collagen, hyaluronic acid, brain amine, squalene, etc. However, from the viewpoint of impregnating the cloth 10 and the cloth 20 to exert a moisturizing effect, glycerin and hyaluronic acid are particularly preferred. When the mask 1 is used for daytime use, the ratio of the cosmetic ingredients contained in the medicine is preferably 5-30% by weight. Examples of preservatives include iodopropynyl butylcarbamate, methyl paraben, propyl paraben, phenoxyethanol, etc., but from the viewpoint of exerting resistance to mold In particular, iodopropynyl butylcarbamate is preferred. In addition, in the beauty ingredients, it can also replace the above moisturizing ingredients or include in addition to it: selected from whitening agents (vitamin C derivatives, hydroquinone, arbutin, etc.), astringents (citric acid) , Alum, ethanol, etc.), skin protectants, and skin nourishing agents.

Each of the first cloth 10 and the second cloth 20 is also a sheet-like member, and is composed of an air-permeable sheet such as a non-woven fabric or a woven fabric. The so-called sheet here may preferably be composed of a non-woven fabric formed by a spunbonding method, a meltblown method, a thermal bonding method, a water needle entanglement method, etc., from the viewpoint of holding the drug, especially It is preferably composed of a non-woven fabric formed by the water needle entanglement method. In addition, as the fiber material constituting the sheet referred to herein, 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. In addition, each of the first cloth 10 and the second cloth 20 may have a single-layer structure composed of one sheet, or a multilayer structure composed of two, three or more sheets stacked together. .

The mask body 30 is configured to be three-dimensionally expandable. More specifically, as shown in FIGS. 3 to 5, the mask body 30 has one or more fixed-shaped pleats (pleats) 31 extending in the left-right direction. And, as shown in FIGS. 5 and 6, when the mask body 30 is stretched in the vertical direction to unfold the shape pleats 31 in the vertical direction, the mask body 30 will be stretched in the vertical direction. At this time, the central part in the left-right direction, which is the main part of the mask body 30, is stretched in the up-down direction. Thereby, the mask body 30 can cover a wider range of the face. As shown in FIG. 5, the shaping pleats 31 are folded before they are unfolded. At this time, the mask body 30 is flat in its entirety. On the other hand, as shown in FIG. 6, after the shaping pleats 31 are unfolded, the mask body 30 will expand into a dome shape. In other words, not only does it expand in the up-down direction, but the center part of the up-down direction also expands as if it protrudes forward, and it expands three-dimensionally. In addition, in FIG. 5, for ease of understanding, the mask 1 is drawn in a three-dimensional direction in the front-to-rear direction, but is actually more flat.

The mask body 30 has an upper side L1, a lower side L2 opposite to the upper side L1, a left side L3, and a right side L4 opposite to the left side L3, and the entirety is substantially rectangular before unfolding. As shown in FIG. 1, the first cloth 10 and the second cloth 20 both extend from the left side L3 to the right side L4 of the mask body 30 in the left-right direction. In addition, the first cloth 10 extends from the upper side L1 in the up-down direction to the vicinity of the center line of the mask body 30 in the up-down direction. 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 up-down direction from slightly above the center line in the up-down direction of the mask body 30 to slightly above the lower side L2. The entire second cloth 20 is also substantially rectangular.

As described above, the first cloth 10 is arranged on the upper side L1 side than the second cloth 20 and the second cloth 20 is arranged on the lower side L2 side than 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 further rear side (the side closer to the face and farther from the mask body 30). In addition, in FIG. 1, the lower side of the first cloth 10 that cannot be visually confirmed due to the existence of the second cloth 20 is illustrated by a one-point chain line for reference.

The upper, left, and right sides of the outer periphery constituting the first cloth 10 overlap with the upper sides L1, the left side L3, and the right side L4 of the outer periphery constituting the mask body 30, respectively. In addition, the first cloth 10 is fixed to the mask body 30 along the full width of the upper, left, and right sides. In addition, the line C1 shown in FIGS. 1 to 4 is the fixing position of the display 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 its lower side. Therefore, the first cloth 10 and the mask body 30 facing the first cloth 10 are configured in a bag shape with a downward vacancy.

The left and right sides constituting the outer periphery of the second cloth 20 overlap with the left L3 and right L4 constituting the outer periphery of the mask body 30, respectively. In addition, the second cloth 20 is fixed to the mask body 30 along the full width of the left and right sides thereof (refer to the line C1 in FIGS. 1 and 2). On the other hand, the second cloth 20 is not fixed to the mask body 30 along its upper side, but is fixed to one or more fixing points P1 of the mask body 30 along its lower side.

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 part 20D is fixed to the mask body 30 at four fixing points P1. These fixed points P1 are located across the center of the mask body 30 in the left-right direction, and two fixed points P1 are arranged in the vicinity of the left and right sides. The lower part 20D is not fixed between the two fixing points P1 and P1 on the inner side, and is not fixed from the leftmost fixed point P1 to the left end 20L, from the rightmost fixed point P1 to the right end 20R. The time is not fixed either.

The method of fixing the cloths 10 and 20 to the mask body 30 can be appropriately selected. For example, methods such as thermal welding (including ultrasonic welding) or sewing can be used. In this embodiment, thermal fusion is applied in a broken line along the line C1 shown in FIGS. 1 to 4.

As described above, the mask body 30 will be three-dimensionally unfolded when it is worn on the face of the user. At this time, as shown in FIGS. 2 and 6, the first cloth 10 and the second cloth 20 are also three-dimensionally unfolded, and the lower part of the first cloth 10 and the upper part of the second cloth 20 slightly protrude forward. Thereby, the cloths 10 and 20 can closely contact the parts of the face having a three-dimensional structure, such as the nose and the corners of the mouth. In addition, the cloths 10 and 20 may be in close contact with relatively flat areas on the face, such as areas surrounding the cheeks or the left, right, and lower sides of the mouth.

When the mask body 30 is unfolded, the first cloth 10 and the second cloth 20 are unfolded so that the area where the two overlapped becomes smaller. Therefore, when the mask body 30 is worn on the face, the contact area between the first cloth 10 and the second cloth 20 and the face increases, and the adhesion between the mask 1 and the face can be improved. Therefore, the mask 1 can effectively prevent viruses, bacteria, dust, etc. from entering the mouth or nose. In addition, in this embodiment, the beauty ingredients impregnated in the cloth 10 and the cloth 20 can be efficiently applied to the face due to such high adhesiveness.

In addition, as described above, the first cloth 10 is not fixed to the mask body 30 along its lower edge, and the second cloth 20 is not fixed to the mask body 30 along its upper edge. Therefore, the lower part of the first cloth 10 and the upper part of the second cloth 20 are not excessively stretched forward in accordance with the swelling of the mask body 30. 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 part of the second cloth 20 is not excessively stretched forward in response to the swelling of the mask body 30 except for the vicinity of the center in the left-right direction where the fixed point P1 is arranged. Therefore, the first cloth 10 and the second cloth 20 can closely follow the face.

When the mask body 30 is unfolded, a gap S1 is formed between the first cloth 10 and the second cloth 20 mainly in the center portion of the mask body 30 in the left-right direction (refer to FIGS. 2 and 6). The gap S1 can mainly accommodate the mouth and nose of the user. Therefore, when the user wears the mask 1, although the first cloth 10 and the second cloth 20 are in close contact with the user's face, the user can still breathe easily.

Before unfolding the mask 1, set the length of the first cloth 10 in the up and down direction to R1, and set the length of the second cloth 20 in the up and down direction to R2, and set the overlap between the first cloth 10 and the second cloth 20 The length in the vertical direction is R3. At this time, from the viewpoint of sufficiently ensuring the contact area between the cloths 10 and 20 and the face, R3/R1≧0.1 is preferable, and R3/R1≧0.2 is preferable, and R3/R1≧0.3 is more preferable. Also, from the same point of view, R3/R2≧0.1 is preferable, R3/R2≧0.2 is preferable, and R3/R2≧0.3 is more preferable. Also, from the same point of view, R3≧0.5cm is preferable, R3≧1.0cm is preferable, and R3≧1.5cm is more preferable.

From the viewpoint of sufficiently ensuring the clearance S1 between the accommodating nose and the mouth, R3/R1≦0.8 is preferable, and R3/R1≦0.7 is preferable, and R3/R1≦0.6 is more preferable. Also, from the same viewpoint, R3/R2≦0.8 is preferable, R3/R2≦0.7 is preferable, and R3/R2≦0.6 is more preferable. Also, from the same viewpoint, R3≦4.0cm is preferable, R3≦3.5cm is more preferable, R3≦3.0cm is more preferable, and R3≦2.5cm is still more preferable.

The ear strap 40 has a pair of left and right rope members 41 and 42. The two ends of the left cord member 41 are respectively fixed near the upper end and the lower end of the left end of the mask body 30, and the cord member 41 and the left end of the mask body 30 together form a closed loop. Similarly, the two ends of the rope member 42 on the right side are respectively fixed near the upper end and the lower end of the right end of the mask body 30, and the rope member 42 and the right end of the mask body 30 together form a closed loop. Thereby, 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. For example, methods such as thermal welding (including ultrasonic welding) or sewing can be used.

From the point of view that the cord members 41 and 42 can be firmly hooked to the ears regardless of the size of the user's face, the cord members 41 and 42 should preferably be stretchable along their long sides. Moreover, the material which comprises the rope members 41 and 42 is not specifically limited, For example, polyester etc. can be used.

To the mask body 30, a linear nose piece 50 is fixed along the upper side L1. The nose piece 50 can be easily bent and is made of a plastically deformable material, for example, it can be made of plastic resin or metal. The nose piece 50 can be bent along the shape of the nose when the user wears the mask 1 and plays a role of narrowing the gap between the mask 1 and the nose. Furthermore, as shown in FIGS. 5 and 6, in the present embodiment, the mask body 30 is folded forward along the upper side L1 and the lower side L2, and is overlapped in two layers at the upper and lower sides. The nose piece 50 is embedded in the upper part of the mask body 30 between the two overlapping parts. Therefore, in FIGS. 1 to 4, the nose piece 50 cannot be visually confirmed originally, but for reference, the position of the nose piece 50 is illustrated by a dotted chain line. In addition, in this embodiment, in order to prevent the nose piece 50 from falling off the mask body 30, the mask 1 is thermally welded (sewn etc.) so as to surround the nose piece 50 (refer to Figs. 1 to Figs. 4 of the line C1).

For example, the following changes are possible. In addition, the gist of the following modification examples can be combined as appropriate.

＜2-1＞ In the above-mentioned embodiment, both the first cloth 10 and the second cloth 20 are impregnated with a cosmetic ingredient, but only one of them may be impregnated with a cosmetic ingredient. In addition, the beauty ingredient may not be impregnated in either of the first cloth 10 and the second cloth 20. At this time, although the beauty effect brought by the beauty ingredients cannot be obtained, because of the high adhesion of the mask 1 to the face, it is still effective in preventing viruses, bacteria, dust, etc. from entering the mouth or nose. Very useful.

＜2-2＞ In the above-mentioned embodiment, the first cloth 10 and the second cloth 20 are partially overlapped in the vertical direction and arranged side by side. However, for example, as shown in FIG. 7, they may be partially overlapped and arranged side by side in the left-right direction. In addition, in this case, it is also suitable to form a gap S1 between the first cloth 10 and the second cloth 20 when the mask 1 is unfolded.

＜2-3＞ The gap S1 formed between the first cloth 10 and the second cloth 20 when the mask 1 is unfolded may be formed to accommodate only the mouth of the user or only the nose.

＜2-4＞ The number of the shaping pleats 31 is not particularly limited, and it may be one, or the shaping pleats 31 may be omitted from the mask body 30. When the shaping pleats 31 are omitted, for example, the mask body 30 may be loosened before unfolding, and the center portion of the mask body 30 may be piled forward during unfolding, so that the mask body 30 may be three-dimensionally unfolded.
