JP2019-60064

As mentioned above, in recent years, foldable masks that are convenient to carry and store can be manufactured at low cost. However, all of them require joining three or more parts, and significant costs are incurred in the manufacturing of each part and in the process of joining the parts together.

Furthermore, when carrying or storing, there is a problem that not only is it difficult to store due to the unevenness, but also that space is wasted when multiple pieces are stacked one on top of the other.

In view of the above problems, it is an object of the present invention to provide a mask that has a structure that can further reduce manufacturing costs, is less bulky when carried or stored, and does not significantly impair its function as a mask.

The present invention has been made in order to solve the above problem, and is a mask that covers the nostrils and mouth, in which a plurality of sheet materials are laminated, and one sheet material on the wearer's side among the laminated sheet materials is provided. is used as a mounting sheet part, the part other than the mounting sheet part is used as a filter sheet part, both left and right ends of the mounting sheet part and both left and right ends of the filter sheet part are respectively joined, and a notch is provided in the mounting sheet part. It is characterized by forming a holder.

By using the present invention, the number of parts is reduced, and materials, manufacturing man-hours, and unnecessary portions of materials during manufacturing are likely to be reduced.

Furthermore, the mask of the present invention is as thin as ordinary paper, and when folded and packaged, its external dimensions become small, so it cannot be kept in a wallet, card case, business card holder, mobile phone case, etc. all the time. By keeping it with you at all times, it will come in handy in case you forget your mask and go out or lose it.

In addition, it does not take up much bulk even when stored in large quantities, so it is suitable as a mask to be stored for disaster prevention.

In claim 5, elasticity is generated in the ear hook portion 26, which is expected to have the effects of making it easy to hook on the ear, less likely to fall off the ear, and easier to hold on the face of the wearer 50.

FIG. 2 is a perspective view showing a state in which the mask of the present invention is folded into three in the horizontal direction.

The mask of the present invention will be explained using FIGS. 1 to 24.

Note that the vertical direction of the wearer 50 is the vertical direction of the mask, and the horizontal direction of the wearer 50 is the horizontal direction of the mask.

Among the laminated sheet materials, one sheet material on the wearer 50 side is used as a mounting sheet section 12, and the rest other than the mounting sheet section 12 are set as a filter sheet section 10.

Therefore, this mask is composed of an attachment sheet portion 12 and a filter sheet portion 10.

The mounting sheet portion 12 has various functions by providing cutouts. The notch and function will be described later.

The base of this mask is formed by laminating a plurality of sheet materials.

The sheet material is preferably nonwoven fabric, but other materials such as woven cloth or urethane foam may also be used.

In order to store the mask in a space-saving manner, preferably a sheet material as thin as possible is used.

The plane of the sheet material must be large enough to cover at least the nostrils and mouth of the wearer 50.

There are various planar shapes of sheet materials, such as rectangles, polygons, ellipses, ellipses with both ends cut off, and quadrangles with elliptical elements, and they are longer in the horizontal direction than in the vertical direction and are symmetrical. preferable.

FIGS. 1(a) to 1(f) are plan views showing examples of the planar shapes of various sheet materials.

Although it is preferable that the plurality of sheet materials have substantially the same shape and size, they may have different shapes and sizes as long as there is no problem in joining the sheet materials to each other, which will be described later.

The filter sheet section 10 is preferably made of one or more sheets, and is preferably a thin nonwoven fabric with high filtration ability.

When using a nonwoven fabric for the filter sheet portion 10, at least one nonwoven fabric is preferably manufactured by a melt blowing method.

It is preferable that the filter sheet portion 10 uses a sheet material that has breathability.

Both left and right ends of the mounting sheet section 12 and both right and left ends of the filter sheet section 10 are respectively joined. That is, the left ends are joined together, and the right ends are joined together.

Appropriate joining methods include fusion bonding, adhesion, pressure bonding, and sewing, but other methods may also be used. The joining method is common to claims 1 to 5.

The joint portion 14 may be continuous or intermittent. FIG. 2 is a perspective view showing how the parts are intermittently joined. Hereinafter, all the joints 14 in the drawings are intermittent joints.

The material used for the mounting sheet portion 12 is suitably a material that is stretchable and resistant to tearing. Therefore, when a nonwoven fabric is used for the mounting sheet portion 12, a tear-resistant nonwoven fabric such as a nonwoven fabric manufactured by a spunbond method is preferable. The more breathable it is, the better.

Although the mounting sheet portion 12 is made up of one sheet material as described above, it may be made up of a plurality of sheet materials.

As shown in FIG. 3, the mounting sheet portion 12 is provided with a notch in the vertical direction from the upper end to the lower end in the center portion in the horizontal direction, and is divided into left and right parts to form a pair of holders 20 on the left and right sides.

The holder 20 is necessary to hold the filter sheet part 10 on the face of the wearer 50, and the holder 20 can be flipped up from the surface of the filter sheet part 10 and attached to the cheek of the wearer 50, or When the ear hook portion 26 is provided on the ear hook 20, the ear hook portion 26 is used by hanging the ear hook portion 26 on the ear.

FIG. 4 is a perspective view showing the right side of the holder 20 turned up. How to use the holder 20 will be described later.

In addition, at the time of manufacture, a notch may be provided before joining the mounting sheet part 12 and the filter sheet part 10, or a notch may be provided after joining.

The vertical cutout for forming the holder 20 may be continuous, or a small portion of the connecting portion 22 may be left as shown in FIG.

By providing the connecting portion 22, it is possible to prevent one end of the holder 20 on the notch side from shifting and placing weight on other parts during manufacturing, packaging, storage, and the like. Particularly when folded and packaged, since they tend to overlap, it is preferable to provide the connecting portion 22.

By separating the connecting portion 22 by the wearer 50 before putting it on, the holder 20 can be divided into left and right parts for use. Therefore, it is preferable that the connecting portion 22 be within a range where the wearer 50 can easily tear it off by hand.

As described above, the retainer 20 is formed by providing a notch in the attachment sheet portion 12 and is necessary to hold the filter sheet portion 10 on the face of the wearer 50.

As a method of holding the filter sheet part 10 on the face of the wearer 50, a method of providing the adhesive part 24 on the holder 20 and making it adhere to the face will be explained.

As shown in FIG. 6, the filter sheet part 10 is held on the face of the wearer 50 by providing an adhesive part 24 on the turned-up holder 20 and attaching the holder 20 to the cheek of the wearer 50.

The adhesive part 24 uses an adhesive such as double-sided tape or adhesive that can be attached to the cheek area of the wearer 50.

Unlike the method of holding it by hanging it on the ear, the holding method using adhesive has the following effects: it does not put any strain on the ears, it does not interfere with when putting on and taking off glasses, and it does not interfere with accessories such as earrings and piercings that are worn in the ear. You can expect it.

There is also a method of holding the filter sheet section 10 on the face of the wearer 50 by joining the left and right holders 20 at the back of the head or neck of the wearer 50.

In claims 4 and 5, the holder 20 is provided with an ear hook part 26, and the filter sheet part 10 is held on the face of the wearer 50 by being hung on the ear like a general mask. Details will be described later.

In claim 2, in addition to the state shown in FIG. 2, the upper end of the mounting sheet portion 12 and the area between the upper end and both left and right ends are joined to the upper end of the filter sheet portion 10 and the area between the upper end and both left and right ends. In other words, including the scope of claim 1, as shown in FIG. 7, all outer edges are joined except for the area between the lower end and both left and right ends.

The nose pad extension 30 is formed by creating a horizontal notch in the upper part of the attachment sheet portion 12.

The nose pad extension 30 is provided to cover the gap between the nose and cheeks that occurs when the wearer 50 wears the mask, and to improve the fit. Place it so that the side that was attached to it is against the bridge of your nose.

FIG. 8 is a perspective view showing the right side of the holder 20 and the nose pad expander 30 turned up.

Increasing the area of the nose pad expander 30 allows the overall area of the mask to be enlarged when worn, making it easier to cover the nostrils and mouth of the wearer 50.

In claim 3, further from the state shown in FIG. 7, the lower end of the mounting sheet portion 12 and the area from the lower end to both left and right ends, and the lower end of the filter sheet portion 10 and the area from the lower end to both left and right ends are joined. In other words, if the scope of claims 1 and 2 is included, all of the outer edges are joined as shown in FIG.

The chin rest extension tool 40 is formed by providing a notch in the mounting sheet portion 12.

The chin support extension 40 is provided to cover the gap that occurs between the mouth and chin when the wearer 50 wears the mask and to improve the fit. When wearing the mask, the cutout portion is turned up and the surface that was in contact with the filter is placed against the chin.

Figure 10 is a perspective view showing the right side of the holder 20, the nose pad expander 30, and the chin pad expander 40 when turned up.

If the area of the chin rest expander 40 is increased, the area of the entire mask can be expanded when worn, which has the effect of making it easier to cover the nostrils and mouth of the wearer 50.

As described above, the holder 20, the nose pad extension tool 30, the chin rest extension tool 40, etc. are formed by the cutouts in the mounting sheet portion 12, and there are various cutout patterns.

Figures 11(a) to (f) are plan views showing examples of various cutout patterns.
