Description

Specification

Mask Technical Field

The present invention relates to a mask that covers a target portion of a face including a mouth and a nose tip.

Background art

[0002] Conventionally, a mask having a rectangular shape formed by stacking a plurality of gauze sheets, and ring-shaped rubber straps attached to the left and right sides has been widely used. These are types that can be used as flat masks in terms of shape.

[0003] In recent years, masks using non-woven fabric have been developed for the purpose of disposable use, and in use, those that deform in shape following the swelling of the mouth or nose (see, for example, Patent Document 1 and Patent Document 2) ) Has been proposed and commercialized. These are the types that can be used as three-dimensional masks.

[0004] However, the former flat mask has the disadvantage that it is inconvenient for conversations in which the inner surface of the lip is in direct contact with the lips. In this respect, the latter three-dimensional mask is advantageous.

[0005] However, as long as the nonwoven fabric material is used on the inner surface of the mask, the nonwoven fabric fibers may become fluffy due to moving contact with the skin after wearing, and particularly sensitive wearers may get crushed by the fluff. In addition, some wrinkled wearers feel uncomfortable with the hair tips entering between the nonwoven fibers, or the mask and the wearer's skin move relatively with the hair tips between the nonwoven fibers. As a result, it was found that the fluff was further increased.

[0006] Incidentally, in relation to the configuration of the present invention, the one of Patent Document 3 is known, whereas the one of Patent Document 3 is that the entire perforated plastic film is a constituent material of the main body, The difference is that a perforated plastic film is provided on the inner surface of the use surface side of the air-permeable material.

Patent Document 1: Japanese Patent No. 3660036

Patent Document 2: JP 2004-49356 A

Patent Document 3: JP-A-10-211294

Disclosure of the invention Problems to be solved by the invention

[0007] Therefore, a main object of the present invention is to provide a mask that does not cause irritation to the skin without fluff.

Means for solving the problem

[0008] The present invention that has solved the above problems is as follows.

In a mask having a main body portion covering a target portion of a face including a mouth and a nose tip, and a locking portion for locking to an ear,

At least the outer surface side of the mouth portion of the main body portion is made of a material having air permeability, and in the region including the periphery of at least the mouth portion of the main body portion, the portion of the inner surface that directly contacts the skin on the use surface side is perforated plastic. A mask provided with a film.

[0009] (Function and effect)

The use of a perforated plastic film on the inner surface of the use side of the part that directly contacts the skin makes the skin non-irritating and non-fluffing. Therefore, the touch is excellent. Moreover, even if the hair ends of the wrinkles temporarily enter the hole, it seems that the reason is that the hole can easily come out without resistance when the mask is relatively displaced, but there is no sense of incongruity. And then.

Of course, the perforated plastic film does not impair air permeability, ensuring smooth breathing.

[0010] <Invention of Claim 2>

2. The mask according to claim 1, wherein at least an inner surface of the film is subjected to a hydrophilic treatment.

[0011] (Function and effect)

Since most plastic film materials tend to be hydrophobic, when water-repellent films are used, moisture or water vapor tends to stay on the inner surface, and moisture tends to go in and out smoothly. Be looked at. Therefore, if at least the inner surface of the film is subjected to a hydrophilic treatment, water vapor enters and exits smoothly through the opening, and an appropriate humidity can be secured in the mouth area. <Invention of Claim 3>

The mask according to claim 1 or 2, wherein the size of the opening is 0.1 to 3. Omm, and the opening ratio is 10 to 70%.

[0013] (Function and effect)

When the opening is in the above condition, the air permeability and moisture permeability are clearly higher than those of the nonwoven fabric, and the effect of securing an appropriate humidity at the mouth becomes remarkable. In addition, the opening and the opening ratio are not excessively large, so that a wearer with excellent touch and a lot of wrinkles does not feel uncomfortable.

The mask according to claim 1, wherein a filter material is provided on the side opposite to the inner surface of the film on the use surface side.

[0015] (Function and effect)

By using a filter material on the side opposite to the inner surface of the film on the side where the film is to be used, the filter material prevents permeation of influenza and pollen while maintaining excellent touch and without causing discomfort to wearers with many wrinkles Can be used for

5. The mask according to any one of claims 1 to 4, wherein at least the film-side surface of the filter material is subjected to a hydrophilic treatment.

[0017] (Function and effect)

Furthermore, if the filter material is hydrophilically treated at least on the film side, moisture or water vapor that is likely to occur due to breathing or sneezing is less likely to stay on the inner surface, and due to a synergistic effect with the film, moderate humidity is maintained in the mouth area. Can be secured.

The invention's effect

[0018] As described above, according to the present invention, the above-described effects can be obtained. If this is required, a mask with no irritation to fluffy skin is obtained.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

(Example of 3D mask) FIG. 1 and FIG. 2 show an example of a three-dimensional mask, which has a main body 10 that covers the target portion of the face including the mouth and nose tip, and a locking portion 20 for locking to the ear.

[0020] At least the outer surface side of the mouthpiece portion of the main body portion 10 is made of a material having air permeability, and in the region including at least the periphery of the mouthpiece portion of the main body portion 10, a portion that directly contacts the skin on the inner surface of the use surface side. A perforated plastic film 30 is provided.

More specifically, in the example in the figure, for example, the left and right breathable base sheets 1A and IB having a non-woven fabric force are joined by ultrasonic joining or heat welding on the left front side based on FIG. In part 2, the left and right air-permeable base sheets 1A and IB are arranged in a body. The right and left air-permeable base sheets 1A and IB extend as they are to the ears, and a notch is formed in the vicinity of the ears, whereby the locking parts 20 and 20 are formed.

[0022] The left region of the left and right breathable substrate sheets 1A and IB on the basis of FIG. 1 is a portion constituting the main body 10 that covers the target portion of the face including the mouth and the tip of the nose.

[0023] In the main body 10, a portion that directly contacts the skin including the periphery of the mouth, in the illustrated example, covers the central part of the face, covers the nasal head jaws, and covers both sides of the central part. In a region covering almost the entire surface, perforated plastic films 30A and 30B are provided on the inner surface of the mask on the use surface side.

[0024] The perforated plastic films 30A, 30B are fixed to the main body 10 by, for example, left and right film forces, the left and right breathable substrate sheets 1A, and the ultrasonic wave described above in a state of being superimposed on the inner surface of the IB. It is performed by joining together at the time of joining and heat welding.

In place of the above example, as shown in FIG. 5, the ear hooking portion sheets 3A and 3B constituting the ear hooking portion are separated from the air-permeable base sheet 1A and IB constituting the main body portion 10. These may be connected by, for example, ultrasonic bonding or heat welding.

[0026] The mask has uses such as a countermeasure for influenza and pollen. Since the size of influenza virus is different from the size of pollen, it is necessary to adjust the fineness of eyes according to the application. For measures against pollen with a large particle size, for example, the ability to block by simply using a non-woven fabric as the breathable base sheet 1A, IB In the case of blocking influenza virus, the density of very fine fibers is high It is desirable to provide the ability to use non-woven fabric and the filter material 40 on the inner surface side of the breathable substrate sheets 1A and IB. In Fig. 3, this filter material 40 is interposed. An example is shown.

In the example of FIG. 3, a laminated structure using a non-woven fabric having a high fiber density is used as the filter material 40, and is integrated by joining together at the time of ultrasonic bonding or heat welding as described above. The base material sheet 1A and the perforated plastic film 30A and the breathable base material sheet 1B and the perforated plastic film 30B are joined to form a bag, and the filter material 40 is formed in each of the bags. It is also possible to scrape to intervene.

[0028] In the present invention, the three-dimensional means is not limited! In the above example, in order to obtain a three-dimensional mask, a configuration in which the central portion is joined in the vertical direction has been adopted. However, two or more joint portions may be joined, or a lateral portion may be joined. In addition, an appropriate method can be adopted. Further, the shape shown in FIG. 7 shown as a developed shape before joining can be three-dimensionalized by ultrasonic joining or heat welding joining at the joint X. 1 is a base material sheet, and 30 is a perforated plastic film.

[0029] In addition, the force that the body part needs to be breathable may be non-breathable in other parts! /,

[0030] (Example of flat mask)

Fig. 4 shows an example of a flat mask. For example, two woven cloths are used as filter material 40 to form bag portions 41 and 41 on both sides by sewing, and rubber for ears 42 and 42 are formed on both sides. Further, a perforated plastic film 30 is joined to the inner surface of the filter material 40 by an appropriate means. The filter material can be a non-woven fabric, and an ultrasonic seal can be used to form the bag portion 41, and the perforated plastic film 30 can be easily joined.

[0031] (Materials used)

In the present invention, in a region including at least the periphery of the mouth, as long as a perforated plastic film is provided in a portion that directly contacts the skin on the inner surface of the use surface, it may be provided in a wider region.

[0032] The perforated plastic film can be obtained by a known forming method. For example, a film in which a thermoplastic film is perforated by hot press or the like, or a composite sheet made of this and a nonwoven fabric can be mentioned. When using this composite sheet, the film surface is the inner surface. [0033] It is desirable that at least the inner surface of the film is subjected to a hydrophilic treatment. The means for the hydrophilization treatment is not limited, but it is desirable to apply, for example, glycerol monoolephinate or sorbitan monolaurate to the inner surface of the film. The outer surface (atmosphere side) is also hydrophilically treated.

[0034] The size of the opening D of the film conceptually shown in FIG. 6 is 0.1 to 3. Omm, particularly 0.1 to 1.

Omm is desirable. The opening ratio is preferably 10 to 70%, particularly 20 to 40%. Air permeability 1000 ~10000cc / cm ^2, sec, particularly 2000~5000cc / cm ^2, sec force permeability, moisture ί or 400~100 OgZm ² 'hr, particularly 500~900gZm ^2' hr force desirable. The thickness of the finolem, etc., can be selected mainly from the air permeability and moisture permeability, but is preferably 15 to 50 m.

[0035] It is desirable that the raising of 0.1 mm or more by the surface fluff test described later is zero. In addition, it is desirable that the brushing of 0.1 mm or more in the surface fluff test after the Gakushin test (acceleration test) rubbed 20 times with artificial leather (“Sablare” manufactured by Idemitsu Techno Fine Co., Ltd.) is zero. In the present invention, at least in the region including the periphery of the mouth, the force having a laminated structure of at least two layers by the perforated plastic film and the base sheet is made into three layers including the filter material 40 as described above. It is possible to have more than one layer.

[0036] The base sheet may be a woven fabric, but it is desirable to use a non-woven fabric. As the nonwoven fabric that can be suitably used, it is preferable to select a material force that is breathable and does not irritate the skin. For example, a non-woven fabric that can also be used for manufacturing methods such as melt blown, spun bond, air through, point bond, needle punch, and spun lace is used. A melt-prone nonwoven is particularly desirable. It is preferable to use elastic nonwoven fabric as a material for the ear hook, as well as rubber and other materials. For example, polyester copolymer, which is a block copolymer of polyether, polyester, or polycarbonate glycol. Examples include coalesced, polyamide-based, polyurethane-based elastomers, and laminates of these and non-woven fabrics.

[0037] As a filter material mainly interposed between layers, a nonwoven fabric obtained by a manufacturing method such as meltblown, spunbond, air-through, point bond, needle punch, and spunlace can be used. Example

[0038] (Basic test)

Table 1 shows the characteristics of various materials used for mask formation. Here, the perforated film 1 is a mesh film manufactured by PGI (Polymer Group, Inc.) of the United States, and the perforated film 2 is a mesh film manufactured by PANTEX of Italy.

[0039] The test method is as follows.

(1) Air permeability: Measured according to Gurley method specified in JIS P 8117

(2) Moisture permeability: Measured according to the cup method stipulated in JIS Z 0208

(3) Surface fluff test (FRT): One test piece (size: 35mm x 250mm) is dried (drying temperature: 100 ° C), and then 100 in the measurement range with even intervals in the longitudinal direction. This is a test to measure the total number of brushed parts in a place and convert to 1000mm (measurement range: 4mm X 60mm) o

More specifically, as shown in FIG. 8, one test piece (size: 35 mm x 250 mm) is dried with an IR heater (drying temperature: 100 ° C), for example, and then evenly in the longitudinal direction. This is a test in which the total number of raised parts at 100 points in a measurement range with a long interval is measured by, for example, image analysis and converted to 1000 mm (measurement range: 4 mm x 60 mm).

Here, “converted to 1000 mm” is to convert the number of raised parts (measured value) in the actual measurement range of 60 mm into the number of raised parts (calculated value) when the measured range is 1000 mm.

For this surface fluff test, for example, 1090FRT (Fiber One 'Rising' Tester) manufactured by Fibro Co., Ltd. can be used. As shown in Fig. 9, the company's tester changed the transport direction by 90 degrees after drying it with an IR heater in the process of transporting one specimen in the longitudinal direction. This is a testing machine that captures image of raised hair and obtains imaging information, analyzes this imaging information, and measures the total number of raised hair. The number of test pieces to be sampled is not particularly limited. However, as a matter of course, the greater the number of samples, the better the accuracy, usually 3 or more, preferably 5 or more.

[0040] [Table 1]

[0041] From the results in Table 1, it is clear that the characteristics as a direction mask using a perforated film are excellent.

[0042] (Example)

Using the apertured film 1, a mask shown in FIG. 5 was produced. Here, Kuraray's spunlace nonwoven fabric is used as the base sheet, and GPF (Golden Phoenix Fiberwebs, Inc.) stretch nonwoven fabric from the Republic of China is used as the ear cover sheet 3 for 10 men to use for one week. Provided. As a result, all 10 males were evaluated as having excellent touch to the commercial cold and pollen masks shown in Table 1.

Industrial applicability

[0043] The present invention can be applied to a wide range of uses in addition to a mask covering the nose and mouth for the purpose of blocking allergens in hay fever and the like, and preventing infection in colds and the like.
