Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved mask.

[0002]

2. Description of the Related Art Most of sanitary masks used in food factories and precision machinery factories are disposable, so that the manufacturer has a relatively simple structure in order to provide them at low cost. For example, the basic configuration is that a filter material such as a non-woven fabric is punched into a square shape and ear straps are provided on the right and left sides of the square.

[0003]

However, when the above-mentioned conventional mask is worn, the upper edge of the mask floats up at the tip of the nose, exhaled air leaks from the gap, and hygiene cannot be maintained. was there.
On the contrary, in the case of the dust mask, there is also a disadvantage that outside air enters through the gap and adversely affects the human body.

In order to solve such inconvenience, the mask is formed into a three-dimensional shape according to the shape of the face, or a metal wire or the like is embedded in the upper edge of the mask so that the metal wire or the like is fitted to the nose muscle when worn. By the means of deforming the mask, it is actually provided that the adhesion of the upper edge of the mask and the nose is improved. However, there is a problem that these cannot be provided at a low price because of the complicated structure. is there. In particular, in the case where a metal wire or the like is embedded, there is also a problem that the metal wire remains even if it is incinerated when it is discarded. In addition, there is a mask provided with a notch on the upper edge, and by matching the nose to this notch, there is one that improves the adhesion from the upper edge of the mask to the cheek to the cheek, but in the case of this conventional mask, Since the notch is formed by cutting the mask material, there is a problem that dust is generated.

The present invention has been made to solve the above problems, and an object thereof is to provide a mask having a simple structure and high adhesion.

[0006]

In order to achieve the above-mentioned object, according to the present invention, in a mask in which an ear hook string is provided on the mask body, the vertical center line of the mask body is folded in the left and right halves. A method was used in which two triangular pieces formed by joining the front and back fabrics were provided on one side of the upper edge. According to this method, since the center of the upper edge of the mask body is formed into a substantially V shape by forming one piece, the shape matches the base of the nose and, when worn, the adhesion from the base of the nose to the cheeks is good. Becomes Further, since the two pieces are formed in the center of the mask main body, it is possible to easily perform the positioning by wearing them as a knob.

According to the second aspect of the present invention, a means of forming one piece by forming an oblique joining line between the vertical center line and the upper edge of the mask body is used. According to this means
Since it is not necessary to join all the materials corresponding to one piece, one piece can be easily formed.

In the third aspect, a means of providing a fold in the mask body is used. According to this means, the height of the tip of the nose can be absorbed by stretching the folds when wearing the mask.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a front view showing a state in which a mask according to an embodiment of the present invention is folded into two equal parts left and right, where 1 is a mask body and 2 is ear hook strings provided at both left and right ends of the mask body 1. is there. Mask body 1
Is selected from materials such as non-woven fabric and charged fiber according to the application, and in the present embodiment, it is die-cut into a square shape. Further, in the figure, 3 indicated by a dotted line is a welding portion, and in the case of the present embodiment, the vertical folding back 1a of the mask main body 1 and the welding portions 3 at both left and right ends are provided to prevent fraying. Furthermore, in this embodiment, the mask body 1 has three folds (pleats).
4 is provided. The welded portions 3 are also provided at the left and right ends of the fold 4, so that the left and right ends of the fold 4 do not expand.

The above-mentioned structure is very common to disposable masks used in food factories and the like, and does not characterize the present invention. Therefore, various changes can be made such as changing the welded portion 3 to stitching or adhesion, omitting the folds 4 or providing four or more folds.

Next, the features of the present invention will be described. The feature of the present invention is that, as indicated by reference numeral 5 in the drawing, one piece is formed by joining front and back cloths to an upper edge corner on the vertical center line (crease) side in the mask body 1 folded in two. It is provided. More specifically, in the case of this embodiment, two pieces 5 are formed by forming an oblique joining line by welding from the vertical center line 1b of the mask body 1 to the upper edge 1c. In other words, not all the front and back fabrics corresponding to one piece 5 are welded. In addition, in the case of this embodiment, the two pieces 5 are formed by providing the joining lines obliquely, but this is an example showing the simplest configuration of the two pieces 5, and the vertical center line 1b and the upper part. All the triangular corners formed by the edge 1c and the one piece 5 may be welded to form one piece.

FIG. 2 is a front view showing a state in which the mask having the above structure is developed. As shown in the same figure, when the mask is developed, the portion just corresponding to the nose rises in the chevron portion 6 by the pieces 5. That is, the width of the upper edge 1c of the mask main body 1 becomes shorter than the entire width of the upper edge by the two pieces 5, and this becomes a surplus, which rises up in the chevron portion 6 in the middle portion of the mask main body 1. Therefore, when the present mask is worn, the nose is housed in the chevron portion 6, and the upper edge 1c of the mask body 1 hardly rises.

Further, as shown in FIG. 3, when the mask is developed, the upper edge 1c of the mask body 1 is developed into a substantially V shape with one piece 5 as an apex. For this reason, especially near the three pieces 5, the upper edge 1c of the mask body 1 is picked up, so that the wearability is good with the upper edge 1c over the nose and cheeks when worn.

FIG. 4 is a use state diagram showing a state where the present mask is worn. When the present mask is worn, as described above, the shape of the upper edge 1c of the mask body 1 and the shape from the nose to the cheeks are substantially the same, and the upper edge 1c is not excessively lifted. Further, since the chevron portion 6 is formed on the tip of the nose of the mask body 1, and the height of the tip of the nose is absorbed by the chevron portion 6 by accommodating the tip of the nose, the upper edge 1c of the mask body 1 is absorbed. The tension for straightening is not applied, and the above-mentioned adhesion from the nose to the cheek is maintained.

Further, in the case of this embodiment, the mask body 1
Since a plurality of folds 4 are provided in the fold, by adjusting the opening degree of the folds 4, it is possible to change the size (height) of the chevron portion 6 and to cover the chin.
Even if there were individual differences in the height of the nose and the length of the chin, it was possible to always use a mask with a good fit.

Further, since the one piece 5 is located exactly at the center of the upper edge of the mask body 1, when the person wears the piece 5, the two pieces 5 are pressed against the nose, and the ear hook string 2 is attached in this state to obtain an accurate result. A mask can also be worn under positioning.

In the above embodiment, the welding is exemplified as the method of forming the two pieces 5, but this may be formed by means such as stitching or adhesion. For example, if the material of the mask body is a non-woven fabric, welding is suitable, and if it is a cloth such as gauze, suturing is suitable, and any material can be bonded. Further, the punching shape of the mask body 1 is not limited to a quadrangle, and may be punched into another shape such as a barrel shape.

[0018]

As described above, according to the present invention,
Since a means of providing one piece on one corner of the upper edge of the folded mask body is adopted, the manufacturing is extremely simple, no dust is generated, and the adhesion between the mask periphery and the face can be enhanced. Further, since the two pieces are formed at the center of the upper edge of the mask body, it is possible to wear them so as to be aligned with the center line of the face.
