Description

The present invention relates to a disposable mask that prevents the glasses from fogging.

In corona sickness, there are increasing opportunities to wear a mask to shield the wearer's mouth during conversations. On the other hand, when a person wearing glasses wears a mask, there is a problem that the glasses become cloudy due to the exhaled breath leaking from the gap beside the nose.

A mask in which a part called a nose fitter is provided on the upper part of the main body in order to close the gap beside the nose is also known. With a nose fitter, it was possible to close the gap by matching the upper part of the mask body to the shape of the nose when wearing it, but it was insufficient to prevent fogging of the glasses.

Therefore, for example, in the mask described in Patent Document 1, a gap is formed between the upper seat member and the cushion member, so that the pressure difference generated between the inside and the outside of the mask due to exhalation while the mask is attached can be obtained. It can be suppressed. Therefore, when the mask is worn, the adhesion between the cushion member of the mask and the face of the wearer can be maintained, so that it is possible to appropriately prevent fogging of the spectacles caused by exhalation leaking from the upper part of the mask. It is said that it can be done.

However, although the mask of Patent Document 1 suppresses the air pressure difference through the gap, when the breathing becomes rough, the air pressure difference cannot be sufficiently eliminated and the exhaled air leaks from the gap beside the nose. There was a risk that the glasses would become cloudy.

Therefore, an object of the present invention is to provide a mask that can prevent fogging of eyeglasses.

In order to achieve the above object, the mask of the first invention is embedded in a mask body formed of a non-woven fabric, ear cords attached near both side edges of the mask body, and near the upper end edge of the mask body. It includes a first shape-retaining wire and a ventilation portion formed in the lower part of the mask body.

Further, the mask of the second invention further includes a second shape holding wire embedded in the vicinity of the lower end edge of the mask body, and the second shape holding wire is bent in the vicinity of the left and right centers to form the ventilation portion. It is characterized by being done.

Further, in the mask of the third invention, the ear strap is formed in a loop shape having a first end portion and a second end portion, and the first end portion is formed in the vicinity of both side edges of the mask body. Is attached near the upper end edge, and the second end portion is attached near the upper and lower centers.

Further, the mask of the fourth invention is characterized in that a lower filter that can be opened and closed in a flap shape is further provided in the lower part of the mask body.

In order to achieve the above-mentioned object, the mask of the first invention includes a mask main body, an ear strap, a first shape holding wire, and a ventilation portion formed in the lower part of the mask main body. With such a configuration, it is possible to eliminate the pressure difference between the inside and outside of the mask by exhaling the exhaled air from the ventilation portion, and prevent the exhaled air from leaking from the side of the nose and fogging the glasses.

Further, the mask of the second invention further includes a second shape holding wire embedded in the vicinity of the lower end edge of the mask body, so that the second shape holding wire is bent in the vicinity of the left and right centers to form a ventilation portion. If this is the case, the ventilation portion can be formed by a simple method substantially similar to that of the first shape holding wire.

Further, in the mask of the third invention, the ear strap is formed in a loop shape having a first end portion and a second end portion, and the first end portion is the upper end edge in the vicinity of both side edges of the mask body. If it is attached in the vicinity and the second end is attached in the vicinity of the upper and lower centers, it is possible to prevent the mask body from being pulled by the ear strap and narrowing the ventilation portion.

The mask of the fourth invention is further provided with a lower filter that can be opened and closed in a flap shape at the lower part of the mask body, so that viruses and the like can be prevented from entering and exiting through the ventilation portion.

It is a front view of the mask of an Example. It is a front view which attached the mask of an Example. It is a side view which attached the mask of an Example.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the components described in the following examples are examples, and the technical scope of the present invention is not limited to them.

(Constitution)
First, the configuration of the mask 1 of the present invention will be described with reference to FIG. The mask 1 of the present invention is a rectangular disposable mask 1 made of non-woven fabric. That is, the mask 1 is composed of the mask main body 10, the ear straps 2 and 2, the first shape holding wire 31, and the second shape holding wire 32 for forming the ventilation portion.

The mask body 10 is formed of a breathable material, for example, a woven fabric such as a non-woven fabric or gauze, or a knitted fabric. Specifically, as the shape of the mask body 10, a square shape having pleats can be adopted.

In addition, the mask body 10 may have a laminated structure such as a non-woven fabric sheet. When the mask body 10 has a laminated structure, the peripheral edges of the sheets used for each layer can be joined. The method of joining the sheets is not particularly limited, but for example, ultrasonic welding, heat welding, adhesion with an adhesive, sewing, or the like can be used.

The size and size of the mask body 10 are not particularly limited, and can be appropriately selected according to the size and preference of the wearer's face. For example, a mask for men can be formed so that the width is 16 cm to 17 cm and the height is 7 cm to 11 cm. On the other hand, a mask for women can be formed so as to have a width of 14 cm to 15 cm and a height of 7 cm to 11 cm.

The ear cord 2 is a rubber cord formed in a loop shape. By hanging the ear straps 2 and 2 on the left and right ears, the mask 1 can be held at a position covering the mouth. Then, in the ear straps 2 and 2 of the mask 1 of the present embodiment, the first end portion 21 is attached to the vicinity of the upper end edge of the mask body 10 as before, but the second end portion 22 is different from the conventional one and is attached to the mask body 10. It is installed near the center position in the vertical direction.

That is, the second end portion 22 is attached at a position deviated in the vertical direction from the position of the second shape holding wire 32. With such a configuration, even if the mask body 10 is pulled by the ear strap 2, it is possible to prevent the space formed by the second shape holding wire 32 from being crushed. The method of attaching the ear strap 2 to the mask body 10 is not particularly limited, but for example, ultrasonic welding, heat welding, adhesion with an adhesive, sewing, or the like can be used.

The first shape holding wire 31 is a member that is deformed by applying a force and can hold the deformed state when the force is removed. For example, as the first shape holding wire 31, a plastically deformable metal wire (or thin plate) made of aluminum or iron, a resin wire (or thin plate), or the like can be adopted.

Then, by bending the first shape holding wire 31 into a chevron shape, the vicinity of the upper edge portion of the mask body 10 can be formed into a shape along the human face (particularly the nose), so that the upper edge portion of the mask body 10 can be formed. It is possible to prevent sighs from leaking upward from the vicinity.

The second shape holding wire 32 has substantially the same configuration as the first shape holding wire 31. That is, the second shape holding wire 32 is a member that is deformed by applying a force and can hold the deformed state when the force is removed. For example, as the second shape holding wire 32, a plastically deformable metal wire (or thin plate) made of aluminum or iron, a resin wire (or thin plate), or the like can be adopted.

Then, by bending the second shape holding wire 32 into a chevron shape, a space away from the face can be formed in the vicinity of the lower edge portion of the mask body 10. By communicating this space with the nostrils, it is possible to promote the linear discharge of sigh downward from the vicinity of the lower edge of the mask body 10.

Furthermore, by creating a linear path connecting the nostrils to the lower part of the mask body 10 in this way, the pressure near the lower edge of the mask body 10 is higher than the pressure near the upper edge of the mask body 10. Is also low, almost the same as the external pressure. Then, the sigh emitted from the wearer's mouth is discharged to the outside from the ventilation path at the lower part of the mask body 10. Therefore, it is possible to prevent fogging of the glasses due to wearing the mask 1.

The mask 1 of the present embodiment further includes a lower filter 4 that can be opened and closed in a flap shape at the lower part of the mask body 10. The lower filter 4 can be formed of the same material as the mask body 10. As shown in FIG. 1, the lower filter 4 is attached to the mask body 10 upward. Therefore, when the mask 1 is attached, the lower filter 4 is attached after being bent downward.

(Action)
Next, the operation of the mask 1 of this embodiment will be described with reference to FIGS. 2 and 3. First, a method of attaching the mask 1 will be described. The method of attaching the mask 1 comprises the following steps (1)-(3).
(1) While bending the lower filter 4 downward, hang the ear straps 2 and 2 on the ears.
(2) The first shape holding wire 31 is bent into a chevron shape along the outer shape of the nose so that there is no gap between the mask 1 and the face.
(3) The second shape holding wire 32 is bent into a chevron shape at the center (the position of the jaw) to create a path through which air can pass.

Therefore, in the case of the mask 1 of the present embodiment, the second shape-retaining wire 32 bent at the position of the jaw creates a path through which air can pass, so that the sigh can be smoothly discharged. In this case, since the position of the second end 22 of the ear strap 2 is high, the lower portion of the mask body 10 is not pulled, so that the path through which air passes from the nostrils to the chin becomes straight. By doing so, as a result, fogging of the glasses can be prevented.

Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and design changes to the extent that the gist of the present invention is not deviated are included in the present invention. included.
