  According to the mask of the present invention, the plurality of adhesive layer pieces provided at intervals prevent the intrusion of fine particles while holding the mask on the face, while the skin is easy to move. Discomfort can be reduced, and adverse effects on the skin such as dryness and decreased blood circulation can be reduced.

It is an external view of the back surface of the mask which concerns on embodiment of this invention. It is a side view of the state which mounted | wore with the same mask. It is a top view of the state which mounted | wore with the same mask.

  Hereinafter, preferred embodiments for carrying out the present invention will be described with reference to the drawings. The mask 1 according to the embodiment of the present invention is composed only of a mask body that covers the nose and mouth and prevents entry of fine particles such as dust and pollen in the air. That is, it does not have a string for hanging on the ear.

  The mask 1 has a base 2 made of a fibrous material such as a nonwoven fabric. FIG. 1 is an external view of the back surface of the mask 1. The first plurality of adhesive layer pieces 3, 3,... And the first plurality of adhesive layer pieces 3, 3,... A second plurality of adhesive layer pieces 4, 4,... Provided substantially in parallel are fixed to the base 2. In FIG. 1, a center line T connecting the contact portion to the chin with the contact portion to the chin is drawn.

  The first plurality of adhesive layer pieces 3, 3,... And the second plurality of adhesive layer pieces 4, 4,. That is, one second adhesive layer piece 4 is arranged inside the gap between the two adjacent first adhesive layer pieces 3 and 3 (on the central portion side of the mask 1). More specifically, the second adhesive layer piece 4 has a width slightly larger than the width of the gap between the first adhesive layer pieces 3 and 3 and is in contact with the first adhesive layer pieces 3 or 3 or It is almost in contact.

  Each of the first plurality of adhesive layer pieces 3, 3,... And each of the second plurality of adhesive layer pieces 4, 4,. More specifically, each of the first plurality of adhesive layer pieces 3, 3,... And the second plurality of adhesive layer pieces 4, 4,. The shape of each of the two is a quadrangle, and at the corner of the base 2, each of the first plurality of adhesive layer pieces 3, 3, ... has a shape corresponding to the shape of the corner. Yes. For example, the first adhesive layer pieces 3 and 3 at the center upper part and the center lower part are symmetrical hexagons.

  The width of each of the first plurality of adhesive layer pieces 3, 3,... And the second plurality of adhesive layer pieces 4, 4,. The thickness is relatively short, for example, about 3 mm, since the influence on the ability to prevent the entry of fine particles is small.

  The first plurality of adhesive layer pieces 3, 3,... Are arranged substantially symmetrically about the center line T, and the second plurality of adhesive layer pieces are also substantially centered about the center line T. Are symmetrically arranged.

  The outer peripheral edge of the base 2 is a substantially symmetrical hexagon.

  2 and 3 are a side view and a top view, respectively, with the mask 1 mounted. As shown in these drawings, the central portion of the base 2 is swelled in three dimensions. In addition, 2a has shown the side part of the base 2, 10 has shown a nasal bridge, 11 has shown the cheek upper part.

  The first plurality of adhesive layer pieces 3, 3,... And the second plurality of adhesive layer pieces 4, 4,. Adhesive). The first plurality of adhesive layer pieces 3, 3, ... and the second plurality of adhesive layer pieces 4, 4, ... are fixed to the base 2 as follows, for example. That is, a support sheet such as a nonwoven fabric is prepared, and an adhesive layer is spread thereon. And it cuts into the shape of 1st some adhesion layer piece 3, 3, ... and 2nd some adhesion layer piece 4, 4, ..., and it is the surface of the adhesion layer on the back surface of a support body. An adhesive having a higher degree of adhesion than the portion (for example, an acrylic adhesive having a higher degree of adhesion) is applied and bonded to the base 2.

  Next, the operation of the mask 1 will be described. A state before use of the mask 1 is that the surface of the first plurality of adhesive layer pieces 3, 3,... And the surface of the second plurality of adhesive layer pieces 4, 4,. A release sheet (not shown) is attached. The protective sheet is peeled off so that the first plurality of adhesive layer pieces 3, 3,... And the second plurality of adhesive layer pieces 4, 4,. Wear 1 By adhesion to the face of the first plurality of adhesive layer pieces 3, 3,... And the second plurality of adhesive layer pieces 4, 4,. The mask 1 is held on the face. Since the mask 1 does not have a string for hanging on the ear, the ear and the nose are not deformed, and the shape of the face is almost the same as usual. In addition, since the central portion of the mask 1 is swelled in three dimensions, even if there is a step between the nose bridge 10 and the upper cheek 11, the nose is not compressed by the mask 1, and conversely, it is pulled on the adhesive layer piece. The peeling force does not work.

  As shown in FIG. 3, the mask 1 includes a first plurality of adhesive layer pieces 3, 3,... And a second plurality of adhesive layer pieces 4, 4,. There is no gap between the adhesive layer pieces in a top view. This is because the width of each of the second plurality of adhesive layer pieces 4, 4,... Is larger than the width of each gap between the first plurality of adhesive layer pieces 3, 3,. . As a result, it is possible to almost completely block fine particles from entering from above. Similarly, in the cheek or jaw, the first plurality of adhesive layer pieces 3, 3,... And the second plurality of adhesive layer pieces 4, 4,. Can be almost completely blocked.

  In addition, the mask 1 is restricted in movement in the portion of the skin where a plurality of adhesive layer pieces are bonded, but each of these adhesive layer pieces is provided at intervals, so each has a small area. . And the movement of the skin is open | released at the four adjacent parts of the adhesive layer piece of a small area. Therefore, overall, the skin is easy to move and the discomfort of wearing is not so great and is reduced. For the same reason, adverse effects on the skin such as dryness and decreased blood circulation can be reduced.

  When the mask 1 is temporarily removed from the face, it is bent around the center line T. Then, the first plurality of adhesive layer pieces 3, 3,... And the second plurality of adhesive layer pieces 4, 4,. As a result, the adhesive layer pieces are combined. Thereby, adhesive layer pieces will protect each other's surface, and deterioration of the surface of the adhesive layer piece due to adhesion or drying of dust can be suppressed. Further, in the folded state, the central portion of the mask 1 is hermetically sealed, so that it is possible to prevent fine particles from entering and adhering to the back surface of the base portion 2.

  The contact portion with the nasal bridge 10 is important for holding the mask 1 on the face. When the adhesive layer piece of the contact part to the nose bridge 10 is deteriorated by being pressed down to increase the degree of adhesion or the oil component on the face, the outer peripheral edge of the base 2 is substantially symmetrical vertically, The mask 1 can be used upside down. In this case, since the contact part to the jaw is not pressed down so much and the oil component of the face is not adhered, it can be worn longer when it is contacted to the nasal bridge 10.

  The masks according to the embodiments of the present invention have been described above, but the present invention is not limited to those described in the embodiments, and various design changes can be made within the scope of the matters described in the claims. It is. For example, the shape of the outer peripheral edge of the base portion 2 and the three-dimensional bulge shape of the central portion can of course be determined arbitrarily according to taste or function.
