Description

  In the present invention, in the wearing state, an improvement is made so that a gap is not generated as much as possible between the peripheral portion of the cloth mask body covering the mouth and the nostrils and the face, and a separately prepared air purifying filter and the like. The present invention relates to a mask in which a covering gauze piece used in a state where the inner side surface of the mask is covered when the mask is worn is improved in ease of use such as wearability.

6 and 7 are a perspective view from the inside and a side view showing a worn state of the sanitary mask B1 having an existing general structure.
This hygiene mask B1 is composed of a mask body 51 formed by stacking a plurality of fabrics such as gauze and non-woven fabric so as to cover the mouth and the nostrils, and stringing portions 53 provided on the left and right side edges thereof. And a rubber-ring-shaped ear hanging string 52 which is inserted through each of them.

As a method of manufacturing the mask main body 51, a long strip-shaped gauze is sequentially folded plural times in a rectangular shape from the end, and then the sewing state is applied along the left and right side edges, thereby fixing the laminated state of the fabric. At the same time, a method of forming the string passing portion 53 is adopted.
Furthermore, the middle part of the upper edge side of the mask main body 51 is pinched in a fold shape, and a pinching point 54 is provided, so that the mask can be easily conformed to the three-dimensional shape of the face.

  The width of the mask main body 51 is such that each of the left and right side edges 51a almost reaches an intermediate point between the mouth (both ends of the mouth) and the ear in the wearing state of the mask shown in FIG. It is fixed to.

This is presumably because, in consideration of the material cost of the mask main body 51 and the adhesion of the mask main body 51 to the face, it is appropriate to keep the width dimension to this extent.
Or, it seems that he did not think so strictly about securing the adhesion to the face.

As a method of using the sanitary mask B1, since the inner surface of the mask main body 51 is particularly easily soiled, there is also a method of applying a separately prepared covering gauze piece to the inner surface when applying the mask (see FIG. 2). This is generally done.
It has also been practiced to insert a commercially available sheet-shaped air purification filter into a gap between the fabrics of a mask body 51 made by laminating a plurality of fabrics.

Next, FIG. 8 shows another conventional type of sanitary mask B2 as a side view in a worn state.
In the sanitary mask B2, left and right side end portions of the mask main body 61 are formed in a triangular shape, and a rubber band-shaped ear hanging string 62 is connected to the sharp protruding end.
This type of sanitary mask B2 is often used in various business establishments where harmful dust is generated. When worn, the left and right protruding ends of the mask main body 61 reach the vicinity of the ear as shown in the figure.

JP-A-2003-742: Manufacturing method of hygiene mask (applicant: Shirobato Co., Ltd.)

  In recent years, new viruses that are infectious and more vicious have been discovered one after another, and many people are suffering from hay fever each season, or various production facilities and Considering the health care of people exposed to harmful dusts at waste treatment facilities, etc., the most convenient and effective solution to these problems is hygiene masks. It is necessary to further increase the blocking function.

At that point, the existing sanitary mask B1 has a problem in that the left and right side edges of the mask main body 51 are not properly brought into close contact with the face.
Considering the reason, from the lateral width dimension of the mask body 51, both ends 51a, 51a of the mask body 51 are applied to both cheeks.
However, there are many people whose cheeks are mossy (hollow), and the face around the cheeks has a three-dimensionally irregular surface.
These circumstances are considered as factors that impair the above-mentioned adhesion.

Also, when the hygiene mask B1 is worn as it is while the separately prepared replacement gauze piece is simply applied to the middle part of the inner surface of the mask main body 51, the replacement gauze piece becomes a predetermined one during use. There was a possibility that it would move or slip off from the position.
Further, even when a separately prepared sheet-shaped air purification filter is sandwiched between the overlapping gaps between a plurality of fabrics constituting the mask body 51, the gaps are vertically penetrated, so that the mask During use, there was a risk of slippage from the gap.

  On the other hand, the above-mentioned conventional sanitary mask B2 can be easily understood by comparing with the sanitary mask B1 shown in FIG. There are considerable benefits.

However, on the other hand, with respect to the essential function required of the ear strap, that is, positioning the mask body and pressing it against the face, the ear strap 62 is connected to the sharp side end of the mask body 61 at one point in a supported state. As shown in FIG. 6, the hygiene mask B <b> 2 is inferior to the hygiene mask B <b> 1 in which the ear hanging cord 52 is supported at two points at the upper and lower ends of the side edge 51 a of the mask body 51. Was.

  Therefore, an object of the present invention is to minimize the tightness of the mask body to the face by attaching ear straps to both sides of a rectangular mask body made by laminating a plurality of cloths. It is an object of the present invention to provide a mask which is improved in ease of use, such as a separately prepared cover gauze piece and an air purifying filter.

To achieve the above object, the mask according to the present invention is:
In a square mask body consisting of a laminate of multiple fabrics, with ear straps attached to both ends,
The present invention is characterized in that a pocket useful for improving the usability of the mask is formed by sewing and binding the lower edge side of the mask body.
And, of the plurality of fabrics constituting the mask main body, the innermost fabric located at the innermost side and forming a pocket has its upper end edge slightly so as not to overlap with the upper end edge of the mask main body. Another feature is that it is positioned with its slide down.
It is also characterized in that a separately prepared air purification filter is stored in this pocket.
In addition, the covering gauze piece, which is separately prepared and used while covering the inner surface when the mask is mounted, is characterized in that the upper end portion is bent so as to be hooked on the upper edge portion of the pocket. And
Furthermore, by setting the width of the mask body to a length capable of covering both the left and right cheeks, the adhesiveness between the both end portions of the mask body and the face is greatly improved. .
Specifically, it is preferable to set the size of the mask body for an adult to a width = 17 ± 2 cm and a height = 11 ± 1 cm.
Alternatively, in the state of wearing the mask, in order to make the upper end edge of the mask body adhere to the surface of the nose bulging out of the face, a band-shaped shape made mainly of synthetic resin having plastic deformability is maintained. A member is attached to the upper edge.

The mask according to the present invention having the above-described configuration exhibits more practically excellent functions as listed below than the existing similar products.
(A) A pocket formed by stitching the lower edge of the mask body made of a laminate of a plurality of fabrics greatly contributes to improving the usability of the mask as described below.
(B) The upper edge of the innermost fabric of the mask body in which a plurality of fabrics are overlapped is slightly shifted down so as not to overlap the upper edge of the mask body. It becomes easy to recognize the edge and open the pocket.
(C) If a separately prepared air purification filter is put in a pocket, there is no possibility that the filter will slip off from the mask being used as in the related art.
(D) When the mask is worn, the covering gauze piece used while being covered on the inner surface of the mask body is folded in the upper end portion so as to be hooked on the upper edge of the pocket, as in the conventional case. In addition, it is possible to surely eliminate the risk of slipping off from the mask being used.
(E) In addition, since positioning when the covering gauze piece is covered can be performed easily and reliably, a part of the covering gauze piece does not protrude from the peripheral edge of the mask and is not difficult to see.
(F) By setting the width of the mask main body to a length that can cover both the left and right cheeks, both end portions of the mask main body can be more securely brought into close contact with the face.
(G) At the upper edge of the mask body, a strip-shaped shape holding member made of a synthetic resin having plastic deformability as a main material is attached, so that the mask body is also formed on the nose portion protruding from the face. Can be brought into close contact.
(H) By increasing the width of the mask body, another function of the mask, that is, protecting the face from cold in winter, is also noticeably enhanced.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a plan view of the mask A of this embodiment viewed from the inside thereof, FIG. 2 is a perspective view of the mask A in a state in which a gauze D is covered on its inner surface, and FIG. 4 is a partial longitudinal sectional view taken along the line YY in FIG. 2, and FIG. 5 is a side view showing the wearing state of the mask A.

  As shown in the figure, the mask A is composed of a mask body 1 having a size large enough to cover a mouth, a nostril, and both right and left cheeks by overlapping a plurality of breathable fabrics such as gauze and nonwoven fabric. And a rubber-ring-shaped ear hanging string 2 inserted through a string passing portion 3 provided in a penetrating shape on both side ends thereof.

  To give a specific example of how to make the mask main body 1, a long band-shaped cloth as a raw material, as it is, or a long band-shaped cloth having a width several times the longitudinal width of the mask main body, in the width direction In the state of being folded into a plurality of layers, the layers are sequentially wound from one end side to the other end side so as to have a predetermined width and a predetermined number of stacked layers.

At this time, as shown in FIG. 2, the innermost fabric 1A, which is the final end face of the winding, is slightly slipped down so that the upper edge a does not overlap with the upper edge b of the mask body 1. Position.
Specifically, as shown in the drawing, a method of folding the upper end portion of the innermost fabric 1A inward in a downwardly inclined shape toward the tip end side thereof, or the like may be adopted.
Alternatively, the upper end portion of the innermost fabric 1A may be bent inward by a predetermined width over the entire width.

After that, by providing stitching points V over the entire height near both side edges of the rectangular laminate, the laminate form of the mask main body 1 is fixed, and the string passing portion 3 is formed at the same time.
Further, by providing a stitching point W along the lower edge of the mask body 1 as shown in FIG. 3, between the adjacent fabrics of the mask body 1 made by laminating a plurality of fabrics. Thus, the pocket 4 is formed.
Incidentally, the pockets 4 are naturally formed also in the respective overlapping gaps of the plurality of superposed fabrics.

As shown in FIG. 5, the size of the mask main body 1 is set so that the width of the mask main body 1 is long enough to cover the right and left cheeks of the face.
As a result, as described above, both edges of the mask main body 1 are applied to the cheek surface having a depression or having an irregular convex shape, as described above. In addition, poor adhesion of the mask body 1 to the face can be substantially eliminated.

Incidentally, the size of a conventional cloth-made sanitary mask is for adults and is generally set to 13.5 (width) × 9.5 (length) cm.
On the other hand, the size of the adult mask body 1 according to the present invention is set such that the horizontal width is 17 ± 2 cm and the vertical width is 11 ± 1 cm.

Next, a strip-shaped shape holding member 5 made of a synthetic resin having plastic deformability as a main material is attached to the upper end of the mask body 1 over substantially the entire length thereof.
The shape holding member 5 is bent into a shape following the uneven surface of the nose simply by pressing against the surface of the nose protruding from the face in a state where the mask A is worn, so that the mask body to the nose circumference portion 1 can significantly improve the adhesion.

The plastic deformability is a property of maintaining the forced deformation state even after the object is bent into an arbitrary shape and the bending force is released.
In this embodiment, the shape holding member 5 is made of a synthetic resin having plastic deformability embedded with a reinforcing fibrous material.

Next, the functions of the mask A will be described again below.
Needless to say, the function required of the mask A is to prevent particulate matter such as dust or virus, which is harmful to the body, from being inhaled into the body together with the exhaled breath as much as possible without impeding free breathing. is there.

For this purpose, the first measure is to examine the material and structure of the mask body 1, and the second measure is to consider the adhesion of the mask body to the face as much as possible while keeping the feeling of wearing as good as possible. It is to raise as much as possible.
In the present invention, as a third measure, as described at the beginning, a commercially available air purifying filter C, which has been used in combination with a mask, or an inner surface thereof when the mask is mounted. A measure is taken to improve the usability of the replaceable covering gauze piece D, which is used in a state of being remarkably improved.

Therefore, first, the third measure will be described. As a first point, the pocket 4 is formed in the mask body 1.
Further, as a second point, as shown in FIG. 2, the upper end of the innermost fabric 1A in which the pocket 4 is formed is located at the innermost position among the plurality of laminated fabrics constituting the mask body 1. The edge “a” is slightly shifted downward so as not to overlap the upper edge “b” of the mask body 1.

Therefore, the trouble of searching for the upper end edge a of the pocket 4 with the fingertip while skipping it is omitted, and the operation of opening the mouth of the pocket 4 can be performed quickly.
If the filter C is placed in the bottomed pocket 4 as shown in FIG. 1 and FIG. 3, a plurality of cloths are overlapped and the both ends are stitched as in the conventional case. Unlike the case where the filter C is simply sandwiched in the gap between the fabrics of the mask body that has just been formed, the risk of the filter C slipping off during use of the mask is completely eliminated.

  In addition, the covering gauze piece D, which is separately prepared and used to cover the inner surface when the mask A is worn, is used not only to be attached to the inner surface of the mask body 1 but also shown in FIGS. As described above, the upper end portion may be bent so as to be hooked on the upper edge a of the pocket 4.

In this manner, the danger of the covering gauze pieces D slipping off during the use of the mask A can be reliably eliminated.
Of course, as described above, the upper edge a of the pocket 2 is in a state in which it is very easy to see and the mouth of the pocket 4 is easily opened, so that the above-mentioned latching operation can be performed easily and quickly. I can do it.

Further, by setting the above-mentioned hooking state, the positioning of the covering gauze piece D can be simply and reliably performed as easily understood by referring to FIG.
Therefore, unlike the conventional case, when the covering gauze piece C is simply applied to the inner surface of the mask body, a part of the covering gauze piece D protrudes from the peripheral edge of the mask body and is unsightly. Can be eliminated.

  The effect obtained by making the width of the mask body 1 longer than that of the conventional mask and the effect obtained by attaching the shape holding member 5 to the upper edge of the mask body 1 are described above. It is like that.

FIG. 2 is a plan view illustrating the mask according to the embodiment of the present invention, as viewed from the inside thereof. FIG. 3 is a perspective view showing a state in which a covering gauze piece is attached to the inner side surface of the mask body. FIG. 2 is a longitudinal sectional view taken along the line XX of FIG. 1; FIG. 3 is a partial vertical sectional view taken along the line YY of FIG. 2; It is a side view which shows the wearing state of a mask same as the above. FIG. 2 shows a mask as a conventional example, and is a view corresponding to FIG. 1. FIG. 6 is a diagram corresponding to FIG. FIG. 7 is a view showing a mask as another conventional example and corresponding to FIG. 7.
