As a solution, a sanitary mask combined-use type face pack is provided, which is characterized in that the face pack is composed of a cosmetic sheet in which a nonwoven fabric (A) and a resin film (B) are laminated so that a part of fibers constituting the nonwoven fabric (A) is contained in the resin film (B), and that at least a portion where a nose, a mouth, and ears are located when the face pack is worn has an opening portion.
Description
Technical Field
The invention relates to a combined mask for a sanitary mask.
Background
Conventionally, sanitary masks have been widely used for the purpose of preventing pollinosis or cold. Recently, as one of the measures for preventing infection by a novel coronavirus, it has become indispensable to use a sanitary mask.
However, if the sanitary mask is worn continuously, the portion covering the face, particularly the cheek portion, comes into contact with the sanitary mask for a long time and rubs (rubs) against the sanitary mask, and the skin loses moisture to become dry skin, which is a symptom called "rough skin due to the mask". The "rough skin due to the mask" is caused by the fact that the moisture increases due to the exhaled air accumulated in the mask, the horny substance on the skin surface is swollen, and the moisture to be stored is evaporated and the skin is dried when the mask is removed. As a result, the barrier function of the skin is lost, and the skin is easily affected by ultraviolet rays, pollen, bacteria, and the like, which causes a large number of skin injuries.
As a measure against dry skin, the use of cosmetic facial masks is known, and various cosmetic facial masks have been proposed (for example, patent documents 1 and 2). In order to relieve skin damage caused by "rough skin due to a mask", it is important to moisturize the skin first, and therefore, the use of a cosmetic mask is one of effective means.
However, if the frequency of wearing the sanitary mask is considered, the frequency of use of the cosmetic mask needs to be increased, but since it is difficult to perform a life movement such as walking or talking in a state where the cosmetic mask is attached to the face, it is difficult to secure a time for using the cosmetic mask, and as a result, there is a problem that the frequency of use of the cosmetic mask cannot be increased.
Under such circumstances, a simple countermeasure method for eliminating "rough skin due to a mask" worn by a sanitary mask is desired.

Disclosure of Invention
The invention aims to provide a mask for use with a sanitary mask, which can be worn while retaining moisture as a measure against dry skin such as "rough skin due to the mask", and which does not cause discomfort when worn outside.
The present inventors have conducted intensive studies to solve the above problems, and as a result, have found that a cosmetic sheet having excellent stretchability and a resin film laminated on one surface of a nonwoven fabric is provided with an opening at a portion where a nose, mouth, and ears are located when worn, so that a sanitary mask does not give a sense of incongruity in appearance even when worn, and that the moisturizing cosmetic does not adhere to the sanitary mask due to the resin film even when the nonwoven fabric is impregnated with the moisturizing cosmetic, and have solved the above problems.
Specifically, the present invention is made with the following matters as the gist.
1. A combined mask for a sanitary mask is characterized in that,
in such a manner that a part of the fibers constituting the nonwoven fabric (A) is contained in the resin film (B),
comprising a cosmetic sheet comprising a nonwoven fabric (A) and a resin film (B) laminated thereon,
at least the nose, mouth, and ear parts have opening parts when worn.
2. The sanitary mask combined use type mask according to 1, wherein a cosmetic sheet having a load of 0.75 to 3.5N/25mm when stretched at 50% is used.
3. The sanitary mask combination-use type face pack according to 1 or 2, wherein the nonwoven fabric (A) and the resin film (B) satisfy the following main conditions.
Main conditions
(A) The method comprises the following steps Nonwoven fabric comprising heat-fusible fibers and having a ratio of a transverse stretch length to a longitudinal stretch length (transverse stretch length/longitudinal stretch length) of 1 to 5
(B) The method comprises the following steps A resin film of 5 to 15 μm thickness comprising 60 to 80 mass% of a thermoplastic elastomer and 20 to 40 mass% of a thermoplastic resin, wherein polyethylene or polypropylene is used as the thermoplastic resin
4. The sanitary mask combined-use type mask according to claim 3, wherein a cosmetic sheet using low-density polyethylene as the thermoplastic resin is used.
The mask for use in combination with a sanitary mask according to the present invention is a cosmetic sheet in which a resin film is laminated on one surface of a nonwoven fabric, and an opening is provided in a portion where a nose, a mouth, and ears are located when the mask is worn, so that the mask does not give an uncomfortable appearance even when the mask is worn, does not make breathing difficult, can normally communicate with one another, and can be used in a time zone of ordinary daily life.
The hygienic mask combination type mask of the present invention can prevent "rough skin due to a mask" worn by the hygienic mask and improve the enhancement effect by using a non-woven fabric having excellent stretchability.
The mask pack of the present invention is a mask pack of the type in which a moisture-retaining cosmetic is impregnated into a nonwoven fabric, and thus the "rough skin caused by a mask" which has been conventionally worn by a sanitary mask can be improved at an early stage by a masking effect. Further, the moisture-retaining cosmetic is useful because the moisture-retaining cosmetic does not adhere to the sanitary mask due to the resin film laminated on the nonwoven fabric.

Lamination of layers
The method of laminating the nonwoven fabric (a) and the resin film (B) is not particularly limited, and the nonwoven fabric (a) and the resin film (B) may be laminated by a known method. As an example of an appropriate form, there is a method (extrusion lamination method) in which a resin film (B) containing a thermoplastic elastomer in a heated and melted state immediately after extrusion molding from an extruder or the like is integrated with a nonwoven fabric (a), a method in which a nonwoven fabric (a) and a resin film (B) containing a thermoplastic elastomer are separately produced, a nonwoven fabric (a) in which a thermally fusible fiber contained in the nonwoven fabric (a) is heated and melted and a resin film (B) in a melted or non-melted state, preferably in a melted state, are laminated, and both are heated and pressure bonded to be integrated, and the like. In the present invention, the anchoring effect is achieved by embedding a part of the fibers constituting the nonwoven fabric (a) in the resin film (B), and the fibers constituting the nonwoven fabric are softened or melted by the heat of the resin film (B), and the softened or melted fibers are further welded to the other fibers constituting the nonwoven fabric (a), whereby the fibers and the resin film (B) can be firmly bonded to each other. For example, even when the cosmetic sheet of the present invention is stretched by 50%, from the viewpoint of obtaining a cosmetic sheet in which the nonwoven fabric (a) and the resin film (B) follow each other and peeling is hard to occur, it is preferable to laminate the nonwoven fabric (a) and the resin film (B) by integrating the resin film (B) containing the thermoplastic elastomer in a heated and melted state immediately after extrusion molding from an extruder or the like and the nonwoven fabric. When the resin film (B) and the nonwoven fabric (a) are integrated in this manner, the cosmetic sheet of the present invention has advantages of excellent stretchability and enhancing effect.

In an appropriate form, the resin film (B) containing a thermoplastic elastomer is excellent in stretchability, and therefore has excellent properties such that the elongation after stretching by 50% is small while the stretchability is excellent. In particular, when the nonwoven fabric (a) and the resin film (B) are laminated by the extrusion lamination method, the cosmetic sheet of the present invention can firmly bond the nonwoven fabric (a) and the resin film (B), and therefore, the nonwoven fabric (a) and the resin film (B) are further less likely to be peeled off during stretching, and in an appropriate form, the resin film (B) containing a thermoplastic elastomer is excellent in stretchability, and therefore, has excellent properties such that the elongation after stretching by 50% is small.

Also, the "cosmetic sheet when stretched by 50% means" when a sheet having a length of 100mm is stretched by 150mm ", and the unit" N/25mm "means the stress (N) required to stretch a sheet having a width of 25mm by 50%. The load when the cosmetic sheet is stretched by 50% means that the test piece is impregnated with water in an amount of 10 times the mass of the test piece, and then the test piece is stretched at a chuck width of 100mm and a stretching speed of 500mm/min in an atmosphere of room temperature (about 23 ℃) by using a multifunctional material testing machine (model 5582, manufactured by instron corporation), and the load when the test piece is stretched by 50% is measured, and the average value of the loads when the 3 test pieces are stretched by 50% is obtained.
From the viewpoint of obtaining a cosmetic sheet excellent in stretchability and follow-up properties between the nonwoven fabric (a) and the resin film (B) as well as in lifting effect, the cosmetic sheet of the present invention preferably has an elongation of 20% or less, more preferably 15% or less after stretching the cosmetic sheet by 50%, and preferably 7% or more, more preferably 7.5% or more, and even more preferably 8% or more from the viewpoint of obtaining a cosmetic sheet excellent in lifting effect. The elongation of the cosmetic sheet after stretching the cosmetic sheet by 50% in the present invention means that the sheet is impregnated with water in an amount of 10 times the mass of the sheet, and then the sheet is stretched at a chuck width of 100mm and a stretching speed of 500mm/min in an atmosphere of room temperature (about 23 ℃) by using a multifunctional material testing machine (model 5582, manufactured by instron), and the load of the sheet when stretched by 50% is measured, and the average value of the load of 3 sheets when stretched by 50% is obtained.

Evaluation criteria for feeling of moisture
And 5, dividing: feeling very moisturized
And 4, dividing: feeling comparison and moisture retention
And 3, dividing: in general terms
And 2, dividing: slightly lack of moisturizing sensation
1 minute: lack of moisturizing sensation
The combinations of materials and the average values of the evaluation values of the panelists after 10 minutes, 30 minutes, and 60 minutes from the start of wearing are also shown in table 1.
In table 1, "a" indicates that only the mask a was worn, "B" indicates that only the mask B was worn, "C" indicates that only the simultaneous mask C was worn, "a + B" indicates that the mask B was worn and the mask a was also worn, and "a + C" indicates that the simultaneous mask C was worn and the mask a was also worn.
TABLE 1
As shown in table 1, it was found that by applying (a + C) to the combined mask C impregnated with the cosmetic liquid D in combination with the mask a, the moisture retention property can be improved by the masking effect even after 10 minutes from the start of application, and the high moisture retention property can be maintained even after 30 minutes and 60 minutes thereafter.
Further, it was confirmed that the combined use mask C impregnated with the cosmetic liquid D was worn in combination with the mask a (a + C), and thus the high moisture retention property was maintained even after the evaluation test was completed (60 minutes and later).
On the other hand, it was confirmed that even when (a + B) was worn in combination with the mask a on the mask B impregnated with the cosmetic liquid D, after 10 minutes from the start of wearing, the moisture retention of only the mask B impregnated with the cosmetic liquid D was not different from that of (B), and that even after 30 minutes and 60 minutes thereafter, the moisture retention of only the mask B impregnated with the cosmetic liquid D was degraded as in (B). That is, it was confirmed that the mask B impregnated with the cosmetic liquid D did not have the combined effect of the mask a in terms of moisture retention.
Further, it was confirmed that the combined type mask C containing the cosmetic liquid D was superior to the combined type mask C (a + C) in moisture retention after 10 minutes from the start of wearing, and the effect of improving moisture retention was immediately obtained, by wearing the combined type mask C containing the cosmetic liquid D in combination with the mask a.
From the above results, it was clarified that the mask sheet of the present invention, which is used in combination with a sanitary mask, can immediately improve the moisturizing effect and maintain the moisturizing effect for a long period of time.
In the mask B which simulates the conventional mask, if it is considered that the effect of combining the masks a is not confirmed, the effect of improving moisture retention immediately and the effect of maintaining moisture retention for a long time by combining the hygienic mask combination type mask of the present invention and the hygienic mask are remarkable effects.

Criterion for evaluating dryness of nonwoven fabric
And 5, dividing: is not dried at all
And 4, dividing: hardly dry
And 3, dividing: general purpose
And 2, dividing: slightly dry
1 minute: drying
The combinations of materials and the average values of the evaluation values of the panelists after 10 minutes, 30 minutes, and 60 minutes from the start of wearing are shown in table 2.
In table 2, "B", "C", "a + B", and "a + C" have the same meanings as in table 1.
TABLE 2
As shown in table 2, it was found that by using (a + C) for the combined mask C impregnated with the cosmetic liquid D in combination with the mask a, the drying of the nonwoven fabric portion of the mask contacted with the skin during wearing was suppressed to be extremely good even after 10 minutes, 30 minutes, and 60 minutes from the start of wearing.
On the other hand, it was confirmed that even if (a + B) was worn in combination with the mask a on the mask B impregnated with the cosmetic liquid D, only the mask B impregnated with the cosmetic liquid D was dried to the same extent as (B) after 10 minutes from the start of wearing, and even after 30 minutes and 60 minutes thereafter, only the mask B impregnated with the cosmetic liquid D was dried and progressed in the same manner as (B). That is, even in the dryness, it was confirmed that the mask B impregnated with the cosmetic liquid D did not have the effect of combining the masks a.
Further, it was found that, by using (a + C) for the combined use type face mask C impregnated with the cosmetic liquid D in combination with the mask a, drying of the nonwoven fabric portion of the face mask contacting the skin at the time of wearing was greatly suppressed only from 10 minutes to 60 minutes after wearing, compared with (C) for the combined use type face mask C impregnated with the cosmetic liquid D.
From the above results, it was confirmed that the hygienic mask combined-use type mask of the present invention was used in combination with a hygienic mask, and the drying of the nonwoven fabric portion of the mask contacting the skin during wearing was extremely suppressed for a long time from the wearing.
In the mask B imitating the conventional mask, if it is considered that the effect of combining the mask a is not confirmed, the effect of suppressing drying for a long time by combining the sanitary mask-combined mask of the present invention and the sanitary mask is considered to be a remarkable effect.
Industrial applicability
By combining with the sanitary mask, the mask combined with the sanitary mask does not cause discomfort in appearance and difficulty in breathing, can be used for conversation normally, and can be used in the time of ordinary daily life.
The mask pack of the present invention is useful for preventing "rough skin due to a mask" which has been conventionally worn on a sanitary mask from being worn on the skin by immersing a moisturizing cosmetic in a nonwoven fabric and using the nonwoven fabric in combination with the sanitary mask, and can therefore be used to early improve the masking effect.
