Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention (the invention according to each claim) relates to a face mask as a sanitary article covering a mouth and a nose, and more particularly to a clean room such as an operating room of a hospital or a semiconductor manufacturing plant. And so on.

[0002]

2. Description of the Related Art For example, in a surgical operating room or the like, a face mask or the like is worn with glasses to prevent bacteria from a surgeon or other surgical staff from contaminating a patient. In order to more reliably filter bacteria, the face mask itself is made of a very fine mesh, and air resistance tends to increase. On the other hand, human breath is warmer and more humid than the surrounding air, so it rises through the mask, causing the glasses on the mask to become cloudy and obstruct the view during surgery. Very inconvenient.

As a prior art for preventing such fogging of spectacles, there is, for example, an anti-fog surgical face mask described in Japanese Patent Publication No. 57-39777. This mask is
A sheet of an air-impermeable material such as polyethylene or polypropylene is attached to each of the upper edge and the lower edge of the front surface of the mask, and this sheet is used as a mask in a hung state. . The breath of a person wearing a mask rises away from the glasses by the action of the sheet of the air-impermeable material, so that the glasses do not fog. That is, it is intended to prevent the spectacles from fogging without substantially lowering the performance of the mask.

[0004]

The operating room for performing a surgical operation or the like is fully equipped with an air conditioning system and effectively controls the temperature. However, the illumination light used for the operation has a considerable brightness. In addition, the amount of heat generated from the lighting light is quite large. Therefore, during the operation, the surgeon and the staff also sweat a lot. In addition, the time required for the surgical operation is several hours at the longest, during which the face mask must be worn all the time.
The air-impermeable material itself does not absorb sweat, but intercepts the skin breathing in the area where the sheet is in contact, causing peeling or discomfort, and further irritating the skin to cause inflammation such as rash.

On the other hand, when the clean room is at a high level, for example, in order to eliminate the intrusion of dust having a size of about 0.1 μm, the material of the face mask is a very fine mesh type, and the nose and mouth are covered with the face mask. If it is hidden by the camera, it may be difficult to breathe, and the lens of the glasses being worn may be fogged by the humidity of the exhaled breath.
Therefore, there is an example in which an anti-fog face mask using a tape of a sheet of an air-impermeable material is used even in a clean room. Also, when entering and exiting the clean room, it is necessary to take a certain procedure, and therefore, once entering the clean room, it is generally difficult to go outside.

The clean room itself controls air conditioning at a high level and generally does not sweat, but if used repeatedly for a long time, the sheet of air-impermeable material itself blocks skin breathing and irritates the skin. And cause discomfort.

As a sheet of an air-impermeable material, for example, polyethylene or polypropylene is used. However, these materials are easily stretched. Therefore, in the process of manufacturing a face mask, a polyethylene sheet or the like is used as a face mask. When attaching (setting), it is difficult to adjust the pulling force, and the work efficiency is poor.

Further, during a surgical operation, the surface of the mask may be stained by sweat or blood of the patient, but since the face mask itself is water-absorbing, blood and the like are absorbed by the face mask. If you change your face mask,
During that time, the operation was interrupted, making me ill.

SUMMARY OF THE INVENTION The present invention has been made in view of such problems, and dramatically reduces the adverse effect on the skin without impairing the function of the face mask itself of a high-density material having an anti-fog function. It is an object of the present invention to provide a facial mask that further improves the usability. Another object is to provide a facial mask that is easy to manufacture.

Yet another object is to provide a face mask with improved durability.

Yet another object is to provide a face mask that is less likely to have a stained outer surface.

[0012]

Means for solving the above problem are air-impermeable tapes having a hydrophilic surface so that the tape hangs down from the upper edge of the mask body to the face of the wearer. Is a face mask characterized by being attached to a mask body (claim 1). According to such means, since the tape attached to the mask body has hydrophilicity, it absorbs sweat and does not get rashed or peeled. The hydrophilic tape referred to herein is a property that does not repel water, and includes a tape that has a property of diffusing absorbed sweat and the like to other places. It is preferable that the absorption rate is high, but the value is not limited.

[0013] The tape is an anti-fog tape in which an air-impermeable material sheet and a non-woven fabric subjected to hydrophilic treatment are bonded to each other, and is attached to the mask body so that the non-woven fabric touches the face of a wearer. The above problem can also be solved by a face mask characterized in that the face mask is provided (claim 2).

That is, since the nonwoven fabric which is not hydrophilic by itself has been subjected to the hydrophilic treatment, sweat can be absorbed. Then, when the face tape is worn, the hydrophilically treated nonwoven fabric touches the wearer's face, so that sweat can be absorbed and unevenness and the like can be prevented. Further, the non-woven fabric is breathable and has a property of diffusing absorbed moisture around it, so that the non-woven fabric has a good feeling of use and the absorbed sweat is easily dried.

Here, the non-woven fabric is a garment material, a packaging material, or the like in which fibers are arranged in an indeterminate direction without going through a weaving process, and are entangled, welded, and bonded to form a cloth. Since they are entangled, there is no vertical or horizontal directionality and the edges are not frayed, so they are used for various applications. Further, PP (polypropylene) itself of the nonwoven fabric has no hygroscopicity and is water repellent.

The above-mentioned hydrophilic nonwoven fabric is, for example,
When spinning, it is manufactured by a method of manufacturing a non-woven fabric by applying and drying through a spraying area of a surfactant emulsion.

The air-impermeable material sheet is, for example, polyethylene or polypropylene. Since these sheets are thin and inadvertently stretch, they are bonded to a non-stretchable non-woven fabric. It becomes difficult to stretch itself. Therefore, the work of attaching the anti-fog tape to the face mask is facilitated.

At the time of laminating both, for example, a heat laminating process, that is, a process of forming a layer such as a plastic film or a foam on a cloth, can produce an antifogging tape material.

Further, the antifogging tape is attached so as to cross the mask main body, and is fixed at both right and left ends of the mask main body. The length of the cloudy tape becomes longer,
As the amount of water that can be absorbed increases, the anti-fog tape becomes harder to remove from the face mask, and the durability improves.

Further, in the above-mentioned face mask, the mask body portion has a water-repellent surface side, and a hydrophilic treatment is applied to the back surface of the mask body portion. ) Even if sweat or blood adheres to the surface of the mask main body, it is not absorbed by the face mask itself, so that it is possible to prevent the mask from being stained by wiping.
In addition, since the back side of the mask body is subjected to hydrophilic treatment, sweat on the wearer's face is absorbed by the mask body in addition to the tape. The absorbed sweat and the like permeates around and becomes easier to dry.

[0021] One of the most preferable means of the present invention is a mask body portion formed by folding an intermediate portion in the vertical direction so as to partially overlap, a thin film and a nonwoven fabric subjected to hydrophilic treatment. Is bonded, so that the non-woven fabric touches the face of the wearer on the back side of the mask body, so that the nonwoven fabric touches the face of the wearer, from the upper edge of the mask body, A face mask (claim 5), comprising: an anti-fog tape fixed to both right and left ends of the mask body while hanging down on both surfaces of the back surface.

According to this means, the number of the antifogging tapes on the front side and the back side of the mask main body is one, so that the constituent members can be omitted, and the working efficiency can be improved in manufacturing.

As another means of the most preferred embodiment of the present invention, an intermediate portion is formed by folding vertically so as to partially overlap, and the mask body portion has a water-repellent surface side, On the back side of the mask main body portion, a mask main body portion subjected to a hydrophilic treatment, and the mask main body portion traversing the mask main body portion and hanging from the upper edge portion of the mask main body portion to the outside of the mask main body portion while being left and right A thin film fixed at both ends and a non-woven fabric subjected to hydrophilic treatment are bonded to the film, so that the mask body crosses the mask body and the non-woven fabric touches a wearer's face. A face mask comprising: an anti-fog tape fixed at both left and right ends of the mask body while hanging down from the upper edge to the inside of the mask body. And the like.

According to this means, the water repellency effect on the front side of the mask main body and the hydrophilic effect on the back side of the mask main body become more remarkable. In addition, since the two types of film and anti-fog tape are selectively used for the front surface and the back surface, the number of components is increased, and workability is reduced, but a face mask can be supplied according to the situation when worn. It is possible to perform a variety of combinations.

[0025]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described with reference to the drawings.

The appearance of the face mask 1 according to the present invention is shown in FIG.
As shown in (a), it is composed of a mask body 10, an antifogging tape 20, an ear hanging elastic cord 30, and a side tape 40.

The mask main body 10 is fixed with a side tape 40 over one side of the opposite side 12 including the overlapping portion 11 after a single piece of cloth having a very fine rectangular mesh is partially folded at an intermediate portion thereof. Things.

FIG. 3B is a sectional view of the mask body 10. Thus, the folded mask body 10
Has a plurality of folds (overlapping portions) 11. In this embodiment, the folding method is to fold in one direction in order. However, the folding method may be variously conceived, and can be appropriately changed according to an order or the like.

As shown in FIG. 3A, both ends (opposite sides) 12 of the folded mask main body 10 are integrated, so that the overlapping portion 11 does not expand. Both ends 12
Otherwise, since they are not integrated, the overlapping portion 11 can be expanded.

The ear straps 30 are used to hang the ears when the face mask 1 is worn, and are attached to the opposite sides 12 of the folded mask body 10. In this case, the overlapping portion 11 of the mask body portion
Can be extended vertically. In addition, as this modified example, it is also conceivable to attach the ear hanging elastic cord 30 to each of the opposite sides 13, and in this case, it is possible to widen in the left-right direction.

When the antifogging tape 20 is worn on the mask body 10, it hangs down from the upper edge 14 of the mask body to both the mask body front side 15 and the mask body back 16 (FIG. 3 ( b)), and is attached to the upper edge portion 14 of the mask body. The portion of the anti-fog tape 20 that hangs down on the mask body back surface 16 is a portion that contacts the wearer's face when worn. The antifogging tape 20 has a length that traverses the mask main body 10 and is attached to both left and right ends (opposite sides) 12 when worn, so that the antifogging tape 20 is difficult to remove from the mask main body 10. ing.

The anti-fog tape 20 is formed by laminating a thin film 21 of polyethylene and a non-woven fabric 22 made of polypropylene. The bonding is performed by heat lamination.

The thickness of the film 21 is small.
It is about 0 to 15 μm. In addition, the nonwoven fabric 22 is 15 g
/ M ^2, which is quite thin. By bonding the stretchable film 21 and the non-stretchable nonwoven fabric 22 to each other, the entire antifogging tape 20 is hardly stretched.
The work of mounting it to the device becomes easy.

The attachment of the anti-fog tape 20 to the mask body 10 is performed such that the nonwoven fabric 22 side of the anti-fog tape 20 directly contacts the face of the wearer. In the present embodiment, the anti-fog tape 20 is attached to the mask body 10 by welding.

Here, when the nonwoven fabric 22 itself has no hydrophilicity, the nonwoven fabric 22 is subjected to a hydrophilic treatment. As described above, the nonwoven fabric 22 subjected to the hydrophilic treatment absorbs moisture and the like, and has a function of diffusing around after absorption because of its air permeability. The hydrophilic treatment is, for example, a treatment of applying and drying through a spray region of a surfactant emulsion during spinning.

In the present embodiment, the antifogging tape 20 has a two-layer structure, but a non-woven fabric 22 may be bonded to both surfaces of the thin film 21 to form a three-layer structure. By doing so, when attaching the anti-fog tape 20 to the mask main body 10, the direction does not exist, and the workability in the manufacturing process is further improved.

It is also conceivable that a water repellent treatment is performed on the front side 15 of the mask main body and a hydrophilic treatment is performed on the rear side 16 of the mask main body. In this way, since the water scattered from the outside and the blood during the operation are not absorbed by the mask body 10, the hygiene can be ensured by wiping them off, and the wear can be performed. Since the sweat, moisture, etc. of the person is quickly absorbed by the mask body 10 and diffused on the mask body back surface 16,
The usability is improved.

Incidentally, as shown in FIG.
Is the mask body front side 16 on the mask body back side 16
It is attached so as to be shorter than 5 in order to make it easier to breathe by preventing the anti-fog tape 20 from covering the nose of the wearer when worn.

Next, the antifogging tape 20 is applied to the mask main body 10.
A modified example of the case of attaching to the device will be described with reference to FIG. The same thing as the above-described anti-fog tape 20 is cut into two pieces, and the mask body part front side 15 and the mask body part back side 16 are attached one by one. In this case, the hanging length of the anti-fog tape 20 is the same as in the above-described case, and the mounting of the both ends 12 is performed in the same manner.

The antifogging tape 20 is applied to the back side 16 of the mask body.
Is attached so that the nonwoven fabric 22 hits the face of the wearer. On the other hand, on the mask body surface side 15, the film 21 is attached so that the film 21 faces outward. By doing so, the water and the like scattered from the surroundings can be removed from the anti-fog tape 2
It is not absorbed by zero, and a sanitary condition can be ensured. As described above, by using the mask body 10 that has been subjected to the water repellency treatment and the hydrophilic treatment, this effect is more effective.

The antifogging tape 20 to be attached to the mask body surface 15 may be a single layer of, for example, a film 21 alone. Thus, it is possible to provide the face mask 1 with a variety of variations.

[0042]

According to the first aspect of the present invention, since the air-impermeable tape has hydrophilicity and absorbs sweat, it can be worn repeatedly for a long period of time, even if sweat is absorbed. There is less irritation to the skin in areas where it adheres, and the feeling of use is also improved.

According to the second aspect of the present invention, in addition to the above effects, the antifogging tape is made of an air-impermeable material sheet having different elasticity and a non-woven fabric, so that it is difficult to stretch, and The work of attaching the anti-fog sheet to the mask becomes easy.

According to the third aspect of the present invention, in addition to the above-described effects, in a state where the device is attached to the face tape,
The strength of the antifogging tape itself is improved, and the situation where the tape is twisted at the time of mounting can be prevented.

According to the fourth aspect of the present invention, in addition to the above-mentioned effects, while the wearer's own sweat and the like are absorbed on the back side of the mask main body, moisture such as ambient moisture adheres to the front side of the mask main body. -Absorption can be prevented. In addition, since absorption is performed by the entire back surface of the mask main body, the amount that can be absorbed is large, and furthermore, the permeation to the surroundings makes drying faster.

According to the fifth aspect of the present invention, in addition to the above-mentioned effects, components can be omitted, and work efficiency can be improved in manufacturing.

According to the invention described in claim 6, in addition to the above effects, the water repellency effect on the front surface side of the mask main body and the hydrophilic effect on the back surface side of the mask main body become more remarkable.
In addition, it is possible to supply a face mask according to the situation at the time of wearing.
