JP2011-24942A

By the way, there has recently been a demand for a mask with unprecedented added value, and the inventors of the present invention have conducted extensive studies and have developed a mask with excellent design and functionality.

An object of the present invention is to provide a mask with excellent design and functionality.

In order to solve the above problems, the invention according to claim 1,
A mask comprising a mask main body that covers a target part of the wearer's face, and a pair of left and right ear hooks for locking the mask main body to the wearer's ears,
The mask main body is formed by laminating at least a wearer-side sheet material on the surface closest to the wearer's skin and an outer-side sheet material on the surface furthest from the wearer's skin,
Of the wearer-side sheet material and the outer-side sheet material, only the wearer-side sheet material is formed with an embossment having a convex portion raised in a direction away from the outer-side sheet material;
It is characterized in that the embossed convex portions of the wearer-side sheet material are selectively impregnated with a chemical solution.

With a mask having such a configuration, the embossment is formed on the wearer side sheet material, thereby providing flexibility and improving the softness of the mask (mask main body).
In particular, because the embossment having a plurality of convex portions raised in the direction away from the outer sheet material is formed on the wearer side sheet material, the convex portion of the wearer side sheet material comes into contact with the wearer's skin. Therefore, the area where the mask (mask main body) comes into contact with the wearer's skin can be reduced, and the burden on the skin can be reduced.
Further, by forming an emboss on the sheet material on the wearer side of the mask and applying a pattern due to the emboss, it is possible to improve the designability and appearance of the mask. The embossed pattern on the sheet material on the wearer's side of this mask is invisible when the mask is worn, but is visible when the mask is put on and taken off, so it functions effectively as a one-point design. In other words, this mask has an embossed pattern on the wearer's side sheet material that is the lining, and the embossed pattern on the wearer's side sheet material has added value to differentiate it from other masks. It can be done.

In addition, a mask with such a configuration can provide the mask with the effect (e.g., moisturizing function) of the chemical solution impregnated into the embossed convex portions of the wearer side sheet material, while also providing the mask (mask body part) can be ensured.
For example, the part of the wearer's sheet material that is impregnated with a chemical liquid has lower breathability than the part that is not impregnated with the chemical liquid because the chemical liquid is retained between the fibers of the sheet material (e.g., nonwoven fabric). There is. Therefore, by providing a portion of the wearer-side sheet material that is impregnated with a chemical solution and a portion that is not impregnated with a chemical solution, suitable air permeability is ensured by the portion that is not impregnated with a chemical solution.

The invention according to claim 2 is the mask according to claim 1, which comprises:
The ratio of the embossed convex portions in the wearer-side sheet material is 30% or more and 80% or less.

A mask with such a configuration can ensure suitable ventilation.

The invention according to claim 3 is the mask according to claim 1 or 2 ,
A filter is interposed between the wearer side sheet material and the outer side sheet material.

According to the present invention, a mask with excellent design and functionality can be obtained.

[Explanation of effects]
The mask 100 of the present embodiment includes a mask main body 1 that covers a target part of the wearer's face, and a pair of left and right ear hooks 2 and 3 for securing the mask main body 1 to the wearer's ears. The mask body 1 includes a wearer side nonwoven fabric 13 on the side closest to the wearer's skin, an outer side nonwoven fabric 11 on the side farthest from the wearer's skin, and a wearer side nonwoven fabric 13 and a filter 12 provided between the outer nonwoven fabric 11 are laminated, and the wearer side nonwoven fabric 13 has an embossed portion having a plurality of convex portions 13a raised in a direction away from the outer nonwoven fabric 11. is formed.
In this way, the embossing is formed on the wearer side nonwoven fabric 13 of the mask 100, thereby providing flexibility and improving the softness of the mask 100 (mask main body portion 1).
In particular, since the embossing having a plurality of convex portions 13a is formed on the wearer-side nonwoven fabric 13, the convex portions 13a of the wearer-side nonwoven fabric 13 come into contact with the skin of the wearer. The area where part 1) comes into contact with the wearer's skin can be reduced, and the burden on the skin can be reduced.
Further, by forming an emboss on the wearer side nonwoven fabric 13 of the mask 100 and applying a pattern due to the emboss, the design quality and appearance of the mask 100 can be improved. The embossed pattern on the wearer side nonwoven fabric 13 of this mask 100 is not visible when the mask 100 is worn, but is visible when the mask 100 is put on and taken off, so it functions effectively as a one-point design. In other words, this mask 100 has an embossed pattern that is a one-point design on the wearer's nonwoven fabric 13 that is the lining, and the embossed pattern on the wearer's side nonwoven fabric 13 is added to differentiate it from other masks. It can be of value.

Further, the wearer-side nonwoven fabric 13 of the mask 100 is impregnated with a predetermined chemical solution by coating or the like.
Thereby, the effect derived from the chemical liquid is imparted to the mask 100.
When the medicinal liquid impregnated into the wearer side nonwoven fabric 13 is hyaluronic acids, amino acids, glycerin, collagen, ceramides, glycols, vaseline, etc., it moisturizes the skin or recovers from rough skin. Can be done.
Furthermore, when the medicinal solution impregnated into the wearer-side nonwoven fabric 13 is a fragrance, the fragrance provides a relaxing effect, a refreshing effect, and the like.
Moreover, when the chemical solution impregnated into the wearer-side nonwoven fabric 13 is a deodorant, it is possible to reduce the transmission of unpleasant odors.
In addition, when the chemical solution impregnated into the wearer side nonwoven fabric 13 is a moisture absorbent, it can absorb the water vapor of exhaled breath, and the generation of water droplets on the surface of the mask 100 (the surface of the outer side nonwoven fabric 11) can be suppressed. Can be done.
In this way, by impregnating the wearer-side nonwoven fabric 13 of the mask 100 with a predetermined chemical solution, the mask 100 can be given an effect derived from the drug solution, and the functionality of the mask 100 can be improved.

In this way, a mask 100 with excellent design and functionality can be obtained.

Note that the present invention is not limited to the above embodiments.
For example, as shown in FIG. 6, the embossed convex portions 13a of the wearer-side nonwoven fabric 13 of the mask 100 (mask body portion 1) may be impregnated with a predetermined chemical solution.
The part of the wearer-side nonwoven fabric 13 that is impregnated with the chemical liquid may have lower breathability than the part that is not impregnated with the chemical liquid because the chemical liquid is retained between the fibers of the nonwoven fabric.
Therefore, as in the mask 100 of this embodiment, by providing the wearer-side nonwoven fabric 13 with a part impregnated with a chemical solution and a part not impregnated with a medical solution, the part not impregnated with a chemical solution can provide suitable air permeability. can be ensured.
If the proportion of the embossed convex portions 13a in the wearer-side nonwoven fabric 13 is 30 to 80%, suitable air permeability can be ensured even when the wearer side nonwoven fabric 13 is impregnated with a highly viscous chemical solution. Moreover, the effects of the chemical solution are also suitably exhibited.
In addition, if the proportion of the embossed convex portions 13a in the wearer-side nonwoven fabric 13 is less than 30%, the area of the wearer-side nonwoven fabric 13 that comes into contact with the skin is small, and the effect derived from the medicinal solution may not be fully exerted, so it is preferable. do not have.

In particular, the embossed concave portion of the wearer side nonwoven fabric 13 is close to the filter 12 and the outer surface side nonwoven fabric 11, and the mask main body 1 in that portion is relatively thin, so that breathability can be easily ensured.
For this reason, the embossed convex portions 13a of the wearer-side nonwoven fabric 13 are impregnated with a chemical liquid, and the chemical liquid effect is imparted to the mask 100 while ensuring the breathability of the mask 100 (mask main body 1). did.

Here, a method of impregnating the embossed convex portions 13a of the wearer-side nonwoven fabric 13 with a chemical solution will be described.

[First chemical impregnation method]

The first unit 501 includes an embossing roll 51 having a plurality of protrusions 51a on its outer peripheral surface, a receiving roll 52 disposed opposite to the embossing roll 51, and the like.
The second unit 502 includes a tank 53 in which the chemical solution C is stored, an anilox roll 54 that supplies the chemical solution C in the tank 53 to the transfer roll 55, and the like.

The first chemical liquid impregnation method includes a step of forming an emboss having a plurality of convex portions 13a on the wearer side nonwoven fabric 13 using an embossing roll 51, and applying a chemical liquid C to the convex portions 13a of the embossing formed on the wearer side nonwoven fabric 13. and a step of doing so.
Specifically, by applying a predetermined pressure to the wearer-side nonwoven fabric 13 passing between the embossing roll 51 and the receiving roll 52, one side of the wearer-side nonwoven fabric 13 is pushed out from the other side, forming a raised convexity. After forming the portion 13a, as shown in FIG. 7(b), a chemical solution C is applied to the surface of the convex portion 13a by a transfer roll 55. Note that the chemical solution C can be supplied to the transfer roll 55 using the anilox roll 54 and the tank 53.

That is, when this device 50 is operated, each roller rotates in a predetermined direction, and the wearer-side nonwoven fabric 13 is conveyed in a predetermined direction.
By rotating the embossing roll 51 and the receiving roll 52 around their axes, the wearer-side nonwoven fabric 13 passing between the embossing roll 51 and the receiving roll 52 is embossed.
Further, as the anilox roll 54 rotates around the axis, the chemical solution C is supplied from the tank 53 to the outer peripheral surface of the anilox roll 54. The chemical solution C supplied to the outer peripheral surface of the anilox roll 54 is supplied to the outer peripheral surface of the transfer roll 55 that comes into contact with the outer peripheral surface of the anilox roll 54 .
When the wearer-side nonwoven fabric 13 embossed in the first unit 501 reaches the second unit 502, the transfer roll 55 applies the chemical C to the embossed convex portions 13a of the wearer-side nonwoven fabric 13.
In this way, the embossed convex portions 13a of the wearer-side nonwoven fabric 13 can be impregnated with the chemical solution.

[Second chemical impregnation method]
The device 50 used in the second chemical liquid impregnation method includes, for example, as shown in FIG. A second unit 502 for applying C.
In this device 50, a first unit 501 embosses the wearer's nonwoven fabric 13, and a second unit 502 applies a chemical solution C to the wearer's nonwoven fabric 13 (see FIG. 8(b)). , the formation of the embossing and the application of the chemical liquid are performed using the same process as the apparatus used in the first chemical liquid impregnation method.
Even with such a device 50, the embossed convex portions 13a of the wearer-side nonwoven fabric 13 can be impregnated with the chemical solution.

[Third chemical impregnation method]
The device 50 used in the third chemical impregnation method includes, for example, as shown in FIG. 52, a tank 53 in which the chemical solution C is stored, an anilox roll 54 that supplies the chemical solution C in the tank 53 to the embossing roll 51, and the like.

The third chemical liquid impregnation method employs a method in which a chemical liquid C is applied to the convex portions 13a of the embossing in the step of forming an embossing having a plurality of convex portions 13a on the wearer side nonwoven fabric 13 using the embossing roll 51.
Specifically, as shown in FIG. 9(b), with the chemical solution C attached to the protrusion 51a of the embossing roll 51, a predetermined amount is applied to the wearer's side nonwoven fabric 13 that passes between the embossing roll 51 and the receiving roll 52. By applying pressure, one surface of the wearer-side nonwoven fabric 13 is pushed out from the other surface to form a raised convex portion 13a, and the chemical solution C is applied from the back surface of the convex portion 13a. . Note that the chemical solution C can be supplied to the embossing roll 51 using the anilox roll 54 and the tank 53.

That is, when this device 50 is operated, each roller rotates in a predetermined direction, and the wearer-side nonwoven fabric 13 is conveyed in a predetermined direction.
As the anilox roll 54 rotates around the axis, the chemical solution C is supplied from the tank 53 to the outer peripheral surface of the anilox roll 54. The chemical solution C supplied to the outer peripheral surface of the anilox roll 54 is supplied to the protrusion 51a of the embossing roll 51 that comes into contact with the outer peripheral surface of the anilox roll 54.
As the embossing roll 51 rotates around its axis, the wearer-side nonwoven fabric 13 passing between the embossing roll 51 and the receiving roll 52 is embossed, and at the same time, the embossed convex portions of the wearer-side nonwoven fabric 13 are Chemical solution C is applied to 13a.
In this way, the embossed convex portions 13a of the wearer-side nonwoven fabric 13 can be impregnated with the chemical solution.

In this way, the mask 100 in which the embossed convex portions 13a of the wearer-side nonwoven fabric 13 are selectively impregnated with a chemical solution can be used as a mask that not only has a chemical effect but also ensures good breathability. It can be used suitably.
In particular, when this mask 100 is worn, the protrusions 13a of the wearer's side nonwoven fabric 13 impregnated with a chemical solution come into contact with the wearer's skin, so it is recommended to use a chemical solution effective for moisturizing and skin care. In this way, the burden on the skin can be further reduced.
In addition, this mask 100 also has an embossed pattern on the wearer's side nonwoven fabric 13, so it has added value as a one-point design, and can also be used as a mask 100 with improved design and design. It can be used suitably.

In addition, in the above embodiment, the case where embossing was performed on the wearer side nonwoven fabric 13 having substantially the same thickness, and the embossed convex part 13a was formed on the wearer side nonwoven fabric 13 was explained as an example. The present invention is not limited to this, and for example, as shown in FIG. 10(a), the wearer-side nonwoven fabric 13 may be formed such that the embossed convex portion 13a is thicker than the embossed concave portion. good.
The embossed recesses (between the embossed protrusions 13a) of the wearer-side nonwoven fabric 13 are close to the filter 12 and the outer nonwoven fabric 11, and the mask main body 1 in that area is thin, so breathability is improved. can be ensured.
Further, as shown in FIG. 10(b), the embossed convex portions 13a of the wearer-side nonwoven fabric 13 may be impregnated with a predetermined chemical solution. Even with the mask main body portion 1 using such a wearer-side nonwoven fabric 13, breathability can be ensured.

In addition, in the above embodiments, an example has been described in which an embossing having a plurality of small circular convex portions 13a is formed so as to give a dot pattern (polka dot pattern) to the wearer side nonwoven fabric 13. However, the present invention is not limited to this, and the emboss pattern (shape of the convex portions 13a) is arbitrary, and the wearer-side nonwoven fabric 13 may be provided with an arbitrary pattern.

Moreover, the method of forming embossing on the wearer-side nonwoven fabric 13 is not limited to the above embodiment, and may be any method such as a gravure printing method, a flexo printing method, a letterpress printing method, etc.

In addition, it goes without saying that the specific detailed structure and the like can also be changed as appropriate.
