Abstract

<P>PROBLEM TO BE SOLVED: To provide a mask having a substrate overlappingly provided with cover sheets, installed with hanging/fixing means in both ends, and molded of a polyurethane resin coming into a clay state and freely deformed at ≥60°C, which is formed with at least mouth/nose abutment recessed part on the rear face of the substrate simultaneously with the formation. <P>SOLUTION: By heating the mask at ≥60°C, a user can make the mouth/nose abutment recessed part flexible. In this state, by fitting a mouth and nose in the mouth/nose abutment recessed part and cooling at normal temperatures, a shape of the mouth/nose abutment recessed part can finely be adjusted accordance with one's own face shape. When molding the substrate by a polyurethane resin freely deformed at <60°C, the substrate is easily deformed by one's own body temperature or direct sunlight, or by placing the substrate near a heater, so that the substrate is not used as the mask. If using the mask, a gap is not generated between the mask and a face even if elastically hanging and fixing the mask to ears, so that dust, a disease-causing germ or the like in the air does not invade a user's body. <P>COPYRIGHT: (C)2004,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a respiratory mask,
It is used to cover the nose and mouth and prevent dust and pathogens from entering the body.

[0002]

2. Description of the Related Art A conventional mask of this type is formed by laminating a non-woven fabric and a resin foam, and has excellent shape retention (Japanese Patent Laid-Open No. 7-241349).

[0003]

However, in such a conventional mask, since the mask as a whole has flexibility for the sake of maintaining shape retention, when it is elastically hooked to the ear, There is a disadvantage that a gap is created between the mask and the face, and dust and pathogenic bacteria in the air easily enter the body.

The object of the present invention is to eliminate these disadvantages.

[0005]

In order to achieve the above object, in the mask according to the present invention, a cover sheet is provided on the substrate in a superposed manner, and the mask is provided with a hooking means at both ends thereof, and the substrate is 60 °. Since it is molded with a polyurethane resin that becomes a clay state and freely deforms at C or higher and at the same time as this molding, at least the mouth-and-nose depression is formed on the back surface of the substrate, the user heats the mask to 60 ° C or higher, It is possible to make the mouth-and-nose rest concave portion of the soft. In this state, the user can finely adjust the shape of the mouth-and-nose contact recess by fitting the mouth and nose into the mouth-and-nose contact recess and then cooling at room temperature. . It should be noted that if a substrate is molded with a polyurethane resin that freely deforms at a temperature of less than 60 ° C, it is easily deformed by placing it on one's body temperature or on the side of a direct sunlight heating device, and cannot be used as a mask.

If a cushion material is attached to the back surface of the substrate, the mask can be installed on the face of the user without any gap when using the mask.

If a carbon powder impregnated sheet is detachably arranged on the back surface of the substrate, moisture, dust, pollen and the like in the breath can be easily adsorbed and removed, and the user can easily remove the adsorbed and removed air. It is easy to maintain.

If the substrate is covered with a cloth cover material, it can be used as a conventional mask by manufacturing the cover material with gauze or the like.

2 is a perspective view of the same, and FIG. 3 is a perspective view of a rear seat unit.

1 and 2, M is a mask according to the present invention, and 10 is its substrate. This substrate 10 is 60 ° C
As described above, the polyurethane resin which is in a clay state and can be freely deformed is molded into a curved shape. Reference numeral 13 denotes a mouth-and-nose contact concave portion, which is formed in the central portion on the back surface of the substrate 10. The user heats the substrate 10 to 60 ° C. or more to fit the mouth and nose of the mouth and nose into the mouth and nose fitting recess 11 in a state where the mask is made to be soft, and You can fine-tune the shape to fit your facial shape.

Reference numerals 12, 12 ... Respiratory windows are formed in the substrate 10 in parallel with the horizontal direction. Also 13, 13,
... are mounting holes, and are provided so as to protrude from both end edges of the substrate 10.
Locking belts 60 and 61 are mounted in the mounting holes 13, 13, .... The locking belts 60 and 61 are fastened and fixed on the back side of the user's head by locking means using Velcro (registered trademark, the same applies hereinafter) 62 and 62. The locking belt is not limited to this, and it does not prevent the use of all existing belts.

Next, 14 is one side (loop portion or hook portion) of a frame-shaped velcro tape which is attached to the front surface of this substrate with a double-sided tape. Reference numeral 15 denotes a frame body (corresponding to the “cushion material” of the present invention) attached to the back surface of the substrate 10 with a double-sided tape. The frame 15 is made of polyurethane foam.

Reference numeral 20 denotes a front seat unit (corresponding to a "cover sheet" of the present invention), which is arranged on the front side of the substrate 10. This front seat unit 20 is made of cotton 21
The net (mesh) 22 and the one side (hook side or loop side) 23 of the frame-shaped velcro tape are sequentially sewn on each other. Then, one surface (hook side or loop side) 23 of this frame-shaped velcro tape and one surface (loop portion or hook portion) of the frame-shaped velcro tape of the substrate 10
13, the front seat unit 20 and the substrate 10
It can be removably stacked. The front seat unit 20 is for covering and for enhancing fashionability, and can be reused after being washed to maintain a clean feeling.

Reference numeral 30 denotes a rear seat unit (corresponding to the "cover sheet" of the present invention), which is detachably fitted inside the frame body (the one to which the substrate 10 is adhered) 12 in a state of substantially a gap. Have been combined. This rear seat unit 30 includes a carbon powder impregnated sheet 33, a carbon powder impregnated (solution or scent adsorbing) sheet 34, and a cotton gauze cloth 35 between small frames (cushion material) 31, 32.
It is sandwiched in order and fixed. The charcoal-powder impregnated sheets 33, 34 are made of cloth or non-woven fabric impregnated with charcoal powder of bamboo charcoal. Further, the gauze cloth 35 is used to show a feeling of cleanliness, improve the feel, and pay attention to the fact that dirt is conspicuous, and to indicate the time to replace the rear seat unit 30.

[0015]

The mask according to the present invention is a mask in which a cover sheet is superposed on a substrate, and hooking means are attached to both ends of the mask. The mask is made of a polyurethane resin which is freely deformed into a clay state at 60 ° C or higher. Since at least the mouth-and-nose pad concave portion is formed on the back surface of the substrate during molding, the user can make the mouth-nose pad concave portion of the mask flexible by heating the mask to 60 ° C. or higher. In this state, the user can finely adjust the shape of the mouth-and-nose contact recess by fitting the mouth and nose into the mouth-and-nose contact recess and then cooling at room temperature. . It should be noted that if a substrate is molded with a polyurethane resin that freely deforms at a temperature of less than 60 ° C, it is easily deformed by placing it on one's own body temperature or on the side of direct sunlight heating equipment, and cannot be used as a mask.

Therefore, when this mask is used, even if it is elastically hooked to the ear, no gap is created between the mask and the face, and as a result dust and pathogenic bacteria in the air are contained in the user's body. There is no danger of invading.

If a cushion material is attached to the back surface of the substrate, the mask can be installed on the user's face without any gap when using the mask.

If a carbon powder impregnated sheet is detachably arranged on the back surface of the substrate, moisture, dust, pollen and the like in the breath can be easily adsorbed and removed, and the user can easily remove it. It is easy to maintain.

If the substrate is covered with a cloth cover material, the cover material can be used as a conventional mask by manufacturing the cover material with gauze or the like.
