SOLUTION: This mask 10 is formed by the air permeable particle catching part 20 in an almost elliptic shape in front view at a center part and a peripheral edge fit part 30 formed at the peripheral edge. The air permeable particle catching part 20 is constituted of a center raised part 21 corresponding to the nose of the human and a catching part pleat part 22 corresponding to the mouth. The peripheral edge fit part 30 is formed in a flange shape at the peripheral edge of the air permeable particle catching part 20 and the adhesive material layer 31 is formed on the inner surface. The peeling paper is attached on the adhesive material layer. Also, adhesive material non-continuous parts 33 are formed at the parts corresponding to both side parts of the mouth of the adhesive material layer and turned to peripheral edge fit part pleat parts 34. By performing adhesion to the face by the adhesive material layer, a visual field is prevented from being interrupted by the peripheral edge part of the air permeable particle catching part 20 and the movement of the mouth is coped with by the pleat parts 34.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mask to be worn on a person's nose and mouth.

[0002]

2. Description of the Related Art Conventionally, masks for preventing inhalation of fine particles such as dust, pollen, bacteria, etc. have been used without exception.
It is provided with a string-like body (including an elastic body such as rubber) for hanging on an ear or a head. Conventionally, this cord-like body is generally provided on the short side of a mask body that is generally in a free state and forms a rectangle, and acts to shorten the short side of the rectangular mask body when worn on a human face. For this reason, there is a tendency that it is difficult to adhere to the face, and a gap is formed around the face, so that the capturing of the fine particles becomes insufficient. In addition, since the mounting portion of the string-like body is inevitably thick, the visual field may be obstructed.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a mask which can be more securely adhered to the face without using a cord, and which has a high effect of capturing fine particles. Also,
SUMMARY OF THE INVENTION An object of the present invention is to obtain a mask having a small degree of obstructing the visual field.

[0004]

SUMMARY OF THE INVENTION A mask according to the present invention is provided with an annular fit along the face of a person around the periphery of a breathable fine particle capturing portion covering the mouth and nose of a person, and the annular fit can be adhered to the face of a person. A characteristic adhesive layer is provided, and a release paper is attached to the adhesive layer.

[0005] The adhesive layer of the annular fitting portion may be provided on the entire circumference, but if the portion corresponding to the left and right sides of the mouth of the person is made discontinuous and the discontinuous portion is made into a stretchable fitting fold, Shape followability when a person speaks can be improved. Further, the annular fitting portion can include a metal material whose shape can be freely set.

[0006] It is preferable that the stretchable fold is also provided on the breathable fine particle capturing portion. The gas permeable particulate capturing portion can be made of various materials such as gauze, and can further contain a gas permeable sheet-like organic polymer substance matrix. Specifically, the sheet-like organic polymer substance matrix is preferably made of paper or nonwoven fabric. When the organic polymer substance matrix carries particles of a calcium phosphate compound having a Ca / P ratio of 1.0 to 2.0, a pollen, bacteria, or virus trapping effect can also be obtained.

[0007]

1 to 3 show an example of a basic shape of a mask 10 according to the present invention. This mask 10
Is a substantially oval-shaped air-permeable fine particle capturing unit 20 in a front view at the center.
And a peripheral fitting portion 30 located on the peripheral edge of the gas permeable particulate capturing portion 20. Breathable fine particle capturing unit 20
Has a central ridge 21 corresponding to the person's nose N and a catching fold 22 corresponding to the mouth M.

[0008] The peripheral edge fitting portion 30 is formed in a flange shape on the peripheral edge of the gas permeable fine particle capturing portion 20, and an adhesive layer 31 is adhered and formed on the inner surface (face side) thereof. , A release paper 32 is attached. The adhesive layer 31 may be provided on the entire periphery of the peripheral fitting portion 30,
In order to easily respond to expansion and contraction of the face, the portions 33 on both sides of the mouth are formed as discontinuous portions (non-formed portions) of the adhesive layer, and the adhesive discontinuous portions 33 are formed as peripheral fitting portion fold portions 34. I have.

FIGS. 4 and 5 are sectional views showing examples of the shape of the trapping portion fold 22 of the breathable fine particle trapping portion 20 and the peripheral fitting portion fold 34 of the peripheral fitting portion 30. The trapping portion fold portion 22 may have any shape as long as the breathable fine particle trapping portion 20 can expand and contract when a person speaks. on the other hand,
When the peripheral fitting portion 30 is adhered to the face via the adhesive layer 31, the peripheral fitting portion fold portion 34 has such a shape that a gap is not formed between the peripheral fitting portion 30 and the face as much as possible. In the example of FIG. 4, the capture portion fold 22 is a continuation of a simple V-shaped (U-shaped) cross section, and in the example of FIG. 5, it is a continuation of an Ω-shaped cross section.

The breathable fine particle capturing section 20 may be made of any material that can capture particles in the air. For example, in addition to conventional materials such as gauze, for example, at least one of the layers may be formed of a sheet-like organic polymer substance matrix as proposed by the present applicant in Japanese Patent Application Laid-Open No. 5-115572. FIG. 6 shows an example in which two sheets of organic polymer substance matrix (filter material) 24 are sandwiched between gauze materials 25, and FIG. 7 shows a case where one filter material 24 and gauze material 25 are stacked. It is.

The filter material 24 is made of paper (cellulose) or a non-woven fabric, contains particles of a calcium phosphate compound, and allows air to pass through voids 24a between the fibers. The calcium phosphate compound is 1.0 to
One having a Ca / P ratio of 2.0 is used. For example, hydroxyapatite, tricalcium phosphate, tetracalcium phosphate and the like can be used. These calcium phosphate compounds are preferably used as particles having a particle size of 0.1 to 500 μm. Such a filter material 2
4 is harmful gas in the air, odor components, bacteria, viruses,
It has been confirmed that it has an excellent adsorption effect on pollen and the like.

The present mask 10 having the above structure is used in use.
The release paper 32 is peeled off, and the air-permeable fine particle capturing section 20 is applied to the mouth and nose of a person, and the adhesive layer 31 of the peripheral fitting section 30 is adhered to the face. In this bonded state, since the thick part does not exist on the periphery of the gas permeable fine particle capturing unit 20, the visual field of the human is not obstructed. Further, in particular, when the capturing portion fold portion 22 and the peripheral edge fitting portion fold portion 34 are present, it is possible to sufficiently cope with a change in the shape of the face when a person speaks.

The peripheral fitting portion 30 may include a metal material 35 or a core material whose shape can be freely set. If such a metal material 35 or a core material is inserted, the shape of the face of each person can be more reliably handled. The metal material 35 may be provided only on the upper part corresponding to the nose N of the person.

[0014]

According to the present invention, it is possible to obtain a mask which can be more securely brought into close contact with the face without using a string-shaped body, and thus has a high effect of capturing fine particles and a small degree of obstructing the visual field. it can. Also, since the structure is simple and can be manufactured at low cost, cost performance is high.
