Abstract

To enable inexpensive production/distribution by folding to make a planar shape at non-use or distribution, and to prevent closeness, stuffiness, hotness, and adhesion of a lip stick to a mask during wearing of a mask by forming a three-dimensional shape and pushing and spreading a mask from the inside to create a fixed space.SOLUTION: A folding spacer for a mask is composed of: a space holding body (1) disposed with a ventilation part corresponding to an inside area of a mask filter of a mask (20); a curve shape retaining support body (2) shorter at least in one direction than the space holding body (1); and a locking body for curving in a bow shape in an opposite direction to the curve shape retaining support body (2) due to repelling of the space holding body (1) caused by a length difference made by locking a part each of both ends of the space holding body (1) and the curve shape retaining support body (2). At least one site of the locking body can detachably lock a part each of both ends of the space holding body (1) and the curve shape retaining support body (2).SELECTED DRAWING: Figure 5

Description

The present invention relates to a folding spacer for a mask for comfortable use of the mask.

In order to prevent the spread of infections such as viruses and bacteria, it is effective to wash your hands and gargle, and to wear a mask to prevent splashes from your mouth and nose.
In addition to the effect of preventing splashes from the mouth and nose, the space between the mask and the mouth and nose does not allow the moisture in the exhaled breath to escape directly to the outside, which also has the effect of preventing dry throat. The number of people wearing masks is increasing throughout the year.

There are two general types of masks: flat type, which is often used for cloth masks, pleated type, which is often used for non-woven fabrics, and three-dimensional type, which is often used for cloths and non-woven fabrics. At special sites such as construction sites and medical fields, cup-type and dust-proof masks with a fielder, which have high density and high antibacterial and dustproof effects, may be used.
As the basic structure of the mask, there are many structures in which a pair of strings are provided on the left and right sides of the cloth that covers the mouth and nose, and a flat cloth or non-woven fabric is applied directly to the mouth and nose. The space provided between them is limited, and when wearing a mask, you may feel stuffy, or you may feel the heat due to the temperature of the skin around the mouth and nose and the temperature of the exhaled breath.

In addition, as the area where the mask comes into contact with the skin increases, itching may occur due to irritation of fibers inside the mask, and sweating may occur easily due to an increase in the internal temperature, resulting in stuffiness.
If you are a female, your lips will come into direct contact with the mask, so lipstick will adhere to the mask and your makeup will often collapse.

While the three-dimensional cup type is hard to hit the mouth and nose, it is difficult to breathe due to its high density, and many of them are expensive because they are for business use.

Therefore, for example, in order to widen the space inside the mask, a mask assisting tool as shown in Patent Document 1 has been proposed. This mask assisting tool is provided with an outer edge portion, a nose contact portion, an apex angle portion, a right side inclined portion, a left side inclined portion, and an opening, and is a mounting portion provided at the left and right end positions of the nose contact portion. By fixing it to the mask, it becomes possible to breathe and talk smoothly.

Further, in order to expand the space in the mask, a mask as shown in Patent Document 2 and an auxiliary spacer have been proposed. In particular, this auxiliary spacer has an annular shape that wraps around the user's nose and mouth, is made of a non-breathable material that does not allow outside air to pass through, is flexible, and by attaching the mask body to the face. It is in close contact with the face.

Further, in order to widen the space in the mask, a mask shape holder and a mask as shown in Patent Document 3 have been proposed. In particular, this mask shape holder is attached to the lip side inside the mask, and the upper fixing part attached with a fixing tape etc. that is detachably attached to the center of the upper part of the mask and the fixing that is detachably attached to the lower part of the mask. It consists of a lower fixing portion attached with tape or the like, and a holding portion that maintains a distance between the upper fixing portion and the lower fixing portion.

Since the mask auxiliary tool of Patent Document 1 needs to be molded into a three-dimensional shape from the beginning with injection molded plastic or the like, it is difficult to make it flat when not in use or when it is distributed, and the distribution cost is high because it is bulky. In addition, it is necessary to use a rigid material in order to hold it in a hemispherical shape, so that the force does not escape when an impact or pressure is applied from the outside of the mask, and there is a possibility that pain or bruise may occur in the part in contact with the face.

Since the depth dimension of the space of the auxiliary spacer of Patent Document 2 depends on the thickness of the spacer itself, it is necessary to make the spacer itself thicker in order to increase the space, and as a result, the area where the spacer touches the skin is increased. It will be large, and instead of reducing the area to which the mask adheres, the surface area that the spacer touches will be increased. In addition, although it is flexible, it is made of a material such as rubber and the shape is maintained by the tension of the spacer itself, so repulsion occurs, and it is difficult to make it flat by denting it when not in use or when it is distributed, which can increase distribution costs. Highly sex.

In the mask shape holder of Patent Document 3, it is said that a space is formed around the lips by the tension of the curved holding portion and the adhesive force between the upper fixing portion and the lower fixing portion, but if it is an elastic curved member, it is straight. Since the force to return to the mask is generated, even if the upper and lower sides of the mask are narrowed by the direct force of the support string as proposed, the soft mask such as non-woven fabric or cloth has enough strength to support the curved object to be returned. It is unlikely that it can be provided, and it is difficult to keep the mask from the inside to the outside unless the holding portion itself is made rigid and curved.

Therefore, the present invention is a safe sheet that can be manufactured and distributed at low cost by folding it into a flat surface when not in use or in circulation, and can be appropriately bent to release force even when an impact or pressure is applied from the outside of the mask. By locking the ends of a pair of sheets of different lengths that are formed by the body and forming a three-dimensional shape by the repulsive force, the mask is expanded from the inside to create a certain space, which makes it difficult to breathe when wearing the mask. It is an object of the present invention to provide a folding spacer for a mask, which can prevent stuffiness, heat, adhesion of lipstick to the mask, and the like.

In order to solve the above problems, the folding spacer for a mask according to claim 1 includes a space holding body (1) provided with a ventilation portion corresponding to the inner area of the mask filter (21) of the mask (20) and the space holding. By locking a part of both ends of the curved shape-retaining support (2), which is shorter in at least one direction than the body (1), and the space-holding body 1 and the curved shape-retaining support (2). The space holder (1) repels due to the difference in length, and is characterized by being composed of a locking body (3) for arch-curving in the direction opposite to the curved shape-retaining support (2).

In the folding spacer for mask according to claim 1, at least one of the locking bodies (3) can be detached from both ends of the space holding body (1) and the curved shape-retaining support (2). It is characterized by being able to be locked.
