Abstract

PROBLEM TO BE SOLVED: To provide a filter of high effect while using always a fresh filter by sandwiching the filter between the outside and inside domes attached removably to the shell of a mask. SOLUTION: The shell 4 of a mask sewn with overlapping gauzes is provided on bothe sides with attaching strings 5 and on the rear side with a pair of Hook-and-Loop fasteners 6, 7. In an expansible bag-like cover 8 braided with antibacterially processed rubber are received outside and inside domes 9, 10 made of soft plastic processed antibacterially. When projections of the inside dome 10 are inserted in grooves of the outside to fix both to each other, a frame of the outside dome 9 is adapted to pass through the intermediate part of a window of the inside dome 10 and a frame of the inside dome 10 is adapted to pass through the intermediate part of a window of the outside dome to sandwich a filter 20 between both frames.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mask used by a person having hay fever to prevent inhalation of pollen, prevent inhalation of dust, and prevent colds.

[0002]

2. Description of the Related Art As shown in FIGS. 9 and 10, an inner mask cover 2 is sewn and fixed to a gauze mask 1 provided with rubber cords to be worn around the ears on both ends of a folded gauze. There are masks for housing the inner mask 3 in which the electrostatic filter 24 is sewn on the soft plastic mask frame 23, and a crow-mouth type mask in which the inner mask 3 is provided with a rubber cord.

[0003]

This conventional mask is
Although it is more effective than a commonly used gauze mask, it is more expensive, and functionally the filter comes into direct contact with the mouth, so it contains moisture during use, resulting in poor breathability. There are many unsanitary surfaces such as adhesion around the area, and the crow's mouth mask has a bad appearance, so it is resistant to use, and is generally not used so much.

[0004]

A mask according to the present invention comprises a mask outer cover and a filter sandwiched between the outer dome and the inner dome which are detachably attached to the mask outer cover. A pair of magic fasteners are provided on both sides of the back surface of the mask skin, and an antibacterial stretchable bag-like cover having a pair of magic fasteners attached to and detached from the magic fastener is attached. In this cover, an outer dome and an inner dome made of antibacterial soft plastic were sandwiched with a filter wrapped between the outer dome and the inner dome with a filter cover for charging static electricity and adsorbing dust. Store things. Further, the mask outer cover is colorful or has various shapes so that it can be enjoyably used.

BEST MODE FOR CARRYING OUT THE INVENTION

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The mask of the present invention will be described with reference to the drawings. As shown in FIG. 2, on the both sides of the mask outer cover 4 sewn with gauze, wearing straps 5 such as rubber strings for hanging on the ears and supporting the mask at the mouth are provided. Is provided with a pair of magic fasteners 6. As shown in FIG. 3, it has a pair of magic fasteners 7 which can be attached to and detached from the magic fasteners 6.
There is a stretchable bag-like cover 8 made of rubber and subjected to antibacterial treatment using 300 or the like. The cover 8 accommodates the outer dome 9 shown in FIGS. 4 and 5, which is also made of soft plastic, which is also subjected to antibacterial treatment using Irgasan DP300 or the like, and the inner dome 10 shown in FIG. The outer dome 9 has a recess 11 for receiving the inner dome 10.
1 has a window 14 composed of crosspieces 12 and 13 and a pair of grooves 15. On the other hand, the inner dome 10 has a window 18 formed of crosspieces 16 and 17, and a protrusion 1 to be inserted into the groove 15 of the outer dome 9.
There is 9. The inner dome 1 is inserted into the groove 15 of the outer dome 9.
When the projections 0 of 0 are inserted and fixed to each other, the crosspieces 12 and 13 of the outer dome 9 pass through the middle of the window 18 of the inner dome 10, and the crosspieces 16 and 17 of the inner dome 10 are The filter 20 sandwiched between the windows 14 is pressed firmly while passing through the middle of the window 14 and the crosspiece 1
The layers 2, 13, 16 and 17 are not overlapped with each other so as not to be thickened as a whole. The filter 20 shown in FIG. 7 and FIG. 8 is a filter material 21 in which activated carbon is adhered to a urethane material, which is wrapped around with a filter cover 22 which is antibacterial-treated, electrostatically charged and adsorbs dust, and the periphery is sewn. is there.

The filter 20 is attached to the recess 11 of the outer dome 9.
Then, the outer dome 9, the filter 20, and the inner dome 10 can be integrated by inserting the protrusions 19 of the inner dome 10 into the groove 15 of the outer dome 9 by pressing the inner dome 10 into the groove 15. The integrated product is put in a bag-shaped cover 8 and is housed so that about 1 cm of the circumference of the cover 8 enters from the circumference of the outer dome 9 to the inside like a frame 25 (FIG. 1). Then, the magic fastener 7 of the cover 8 is aligned with and joined to the magic fastener 6 of the mask outer cover 4 to form a mask.

Although not shown, the outer dome 9 and the inner dome 10 are connected by hinges, and holes and holes are provided at both ends to form a snap fastener-like stopper integrally molded. The outer dome 9 and the inner dome 10
Alternatively, the and may be bent at the hinge-like shape and overlapped to sandwich the filter, and the potch may be inserted into the hole and fixed.

Although not shown, the mask outer cover 4 is sewn in a bag shape, and the bag-shaped entrance is formed by accommodating the outer dome 9, the filter 20, and the inner dome 10 integrated therein. May be closed with a magic fastener.

Although not shown in the drawing, the mask outer skin 4 is colorfully dyed, for example, in a refreshing light green color, a cute and smiling mouth line or various characters are drawn, or the outer shape is made into various shapes such as butterflies. , The attachment string 5 and the outer dome 9
May be provided.

According to the mask of the present invention, since the filter is a urethane material with activated carbon attached, the effect as a filter is extremely high and the filter can be replaced. Therefore, it is always necessary to use a fresh filter. I can. This filter is securely housed in the outer dome and the inner dome with large windows, so it does not directly touch the mouth, is hygienic, has good breathability, and can absorb dust etc. became. Moreover, since the mask skin, cover, outer dome, inner dome, filter, etc. can all be disassembled and can be washed, it becomes possible to hygienically and economically use a mask with a high adsorption efficiency for dust and the like. It was In addition, because of its good appearance, masks are used more actively, and it has excellent effects such as the effect of preventive hygiene and the effect of creating a gentle atmosphere for the surrounding people.
