Abstract

The subject of this invention is to provide a disposable dust mask of which tightening straps are not strongly abutted against an upper edge of an ear during the use and will not make the ear hurt. A bowl-shaped mask body having a shape-retaining property is provided. The mask body has straight left and right upper edges with a slightly downward slope, arc-shaped right and left side edges, and symmetric-shaped left and right lower edges when viewed from the front of a protruding surface side of the mask. A pair of left and right tightening straps are shown in front view for attaching the mask body to the user's head. One end of the tightening straps are installed near the upper edge of the protruding surface side of the mask body and the other end is installed near the lower part of the side edge of the protruding surface side of the mask body protruding surface.

Description

Disposable dust mask

The present invention relates to a disposable dust respirator.

Patent Document 1 discloses a disposable dust respirator including a bowl-shaped mask body having a shape-retaining property, and the mask body is shown on the front side of the protruding surface side as a linear left and right upper edge and a circle with a gentle downward slope. The curved left and right side edges and left and right lower edges have a symmetrical shape. In addition, in order to attach the mask body to the user's head, a pair of left and right straps is provided on the front surface. One end of the strap is attached to the protruding surface of the mask body. Near the upper part of the upper edge, the other end is installed near the lower part of the side edge of the face of the mask body.时 When the disposable dust mask of Patent Document 1 is used in a mounted state, the left and right straps are wound around the user's back head using a link. The lower extensions of the left and right straps extend substantially horizontally below the left and right ears, and the upper extensions of the left and right straps abut the upper edges of the bases of the left and right ears of the user, so that the abutment parts extend into a mountain shape at the top.

[Problems to be Solved by the Invention]

In the disposable dust respirator of Patent Document 1, since the end position of the band is lower than the mounting position of the mask body, the mountain-shaped inclination of the upper extension portion of the band becomes large, and the band will strongly abut the ear. The upper edge of the base may cause pain in the ears. The present invention has been developed in view of the above-mentioned problems, and provides a disposable dust respirator with a bowl-shaped mask body having a shape-retaining property. The mask body is shown to have a gently downward slope on the front surface from the protruding side. The linear left and right upper edges, the arc-shaped left and right side edges, and the left and right lower edges are symmetrical shapes. In addition, in order to attach the mask body to the user's head, there are straps showing a pair of left and right on the front surface. At the time, the strap does not strongly contact the upper edge of the base of the ear, and the disposable dust mask is not intended to cause pain in the ear. [Means for solving problems]

In order to solve the above-mentioned problem, the present invention provides a disposable dust respirator, which is characterized by having a bowl-shaped mask body having shape retention properties, and the mask body is shown on the front surface from the protruding surface side to have a gentle downward slope. The linear left and right upper edges, the arc-shaped left and right side edges, and the left and right lower edges have a symmetrical shape, and in order to attach the mask body to the user's head, a pair of left and right bands is provided on the front surface. One end is installed near the upper edge of the protruding surface of the mask main body, and the other end is installed near the lower edge of the side edge of the protruding surface of the mask main body. In the disposable dust mask according to the present invention, one end of the left and right straps is installed near the upper edge of the protruding surface of the mask body. The installation position is higher than that of the disposable dust mask of Patent Document 1, and therefore abuts the left and right. The slope of the band extending from the top of the base of the ear to a mountain shape becomes slower, and the band does not abut the upper edge of the base of the ear strongly, which will not cause ear pain.中 In a preferred aspect of the present invention, the one end of the left and right pair of straps is directly fixed to the mask body, and the other end is a length adjuster fixed to the mask body. Since the upper edge of the mask body is close to the eyes of the user, fixing the length adjuster near the upper edge becomes an obstacle to vision and is dangerous. Therefore, it is preferable that one end of the strap is directly fixed near the upper edge of the mask. The lower part of the side edge of the other mask body is away from the eyes, so the length adjusting tool is fixed near the lower part of the side edge of the mask body, and no problem occurs even if the other end of the length adjusting tool is attached with a strap.

A disposable dust mask according to an embodiment of the present invention will be described. As shown in FIG. 1, the disposable dust mask 1 includes a bowl-shaped mask body 2 having a shape-retaining property, and a ring-shaped face cloth 2 ′ extending radially inward from a peripheral portion of the mask body. . The mask body 2 is shown on the front side of the projecting surface as a left-right upper edge 2a having a linear shape that is gradually inclined downward, and an arc-shaped left-right side edge 2b and a left-right lower edge 2c. The disposable dust-proof respirator 1 is further provided with a pair of straps 3 showing a pair of left and right on the front surface in order to mount the mask main body 2 on the user's head. One end of the strap 3 is mounted near the upper edge 2a of the protruding surface of the mask main body 2, and the other end is mounted near the lower edge of the side edge 2b of the protruding surface of the mask main body 2. The one end of the band 3 is directly fixed to the mask main body 2 by fusion or adhesion, and the other end is fixed to the length adjusting tool 4 fixed to the mask main body 2. Attachment 5 is attached to one of the bands 3.表示 As shown in FIG. 2, when the disposable dust mask 1 is used, the left and right straps 3 are wound around the user's back head and connected with the connecting device 5. The lower extensions of the left and right straps 3 extend substantially horizontally below the left and right ears, and the upper extensions of the left and right straps 3 abut the upper edges of the bases of the left and right ears of the user, so that the abutment portions extend to the top. Yamagata.

In the disposable dust mask 1 after use, one end of the left and right straps 3 is installed near the upper edge 2a of the protruding surface of the mask main body 2. The mounting position is higher than that of the disposable dust mask in Patent Document 1, so it is used in abutment. The mountain-shaped inclination of the upper extension of the band 3 extending from the upper edges of the bases of the left and right ears of the person becomes slow, and the band 3 does not strongly abut the upper edge of the base of the ear, and does not cause ear pain. As shown in FIG. 2 (a), the upper edge 2 a of the mask body 2 is close to the eyes of the user. Therefore, when the length adjuster 4 is fixed near the upper edge 2 a, it becomes a visual obstacle and is dangerous. Therefore, it is preferable that one end of the strap 3 is directly fixed near the upper edge 2 a of the protruding surface of the mask body 2. The lower part of the side edge 2b of the other mask body 2 is away from the eyes. Therefore, the length adjusting tool 4 is fixed near the lower part of the side edge 2b of the mask body. Even if the other end of the strap 3 is attached to the length adjusting tool 4, no problem occurs. [Industrial availability]

The present invention can be widely used in disposable dust respirators, which have a bowl-shaped mask body with shape retention properties, and the mask body is shown on the front side of the protruding surface side as a straight-line upper and lower edges with a gentle downward slope and The arc-shaped left and right side edges and the left and right lower edges have a left-right symmetric shape, and a strap for displaying a pair of left and right on the front surface is provided to attach the mask body to the user's head.
