The mask auxiliary tool 1 according to the embodiment of the present invention is configured as described above. As shown in FIG. 7A, the mask auxiliary tool 1 of this embodiment is attached to the inner surface side of the mask main body 31 of the mask 30.

Next, attachment of the mask auxiliary tool 1 to the mask main body 31 will be described. First, the reversing spring portion 7 of the pair of left and right clips 3 is deformed so as to be curved toward the piece portion 8 to open the reversing spring portion 7. Subsequently, the length of the guard body 2 is adjusted according to the length of the mask body 31 in the left-right direction while being along the mask body 31. The length of the guard body 2 can be adjusted by sliding the first guard portion 4 and the second guard portion 5 outward or inward in the left-right direction.

After adjusting the length of the guard body 2, the mask auxiliary tool 1 is positioned near the center in the vertical direction on the inner surface side of the mask main body 31. Then, the pair of left and right clips 3 are inserted between the reversing spring portion 7 in the open state and the receiving piece portion 8 into both left and right edge portions of the mask main body 31. After that, the reversing spring portion 7 of the clip 3 is received and deformed so as to be curved toward the piece portion 8, so that the reversing spring portion 7 is closed. The reversing spring portion 7 in the closed state receives both the left and right edges of the mask body 31 and presses them against the piece 8, and the left and right edges of the mask body 31 are placed between the reversing spring 7 and the receiving piece 8. It will be in a pinched state. As a result, the clips 3 are detachably attached to both left and right edges of the mask body 31.

Finally, both vertical edges of the mask body 31 are moved in the vertical direction to spread the plurality of pleats 33. In this way, as shown in FIG. 8, the mask auxiliary tool 1 is attached to the mask 30 by a pair of left and right clips 3.

As shown in FIG. 9, the user wears the mask 30 by hanging a pair of left and right ear hooks 32 of the mask 30 to which the mask auxiliary tool 1 is attached on both ears. When the mask 30 is attached, as shown in FIG. 10, the guard body 2 of the mask auxiliary tool 1 is arranged in front of the mouth of the user. In this state, the guard body 2 forms a gap between the user's mouth and the mask body 31. By forming this gap, it is possible to prevent the mask body 31 from sticking to the user's mouth due to the user's breathing.

In addition, an external force may act on the guard body 2 toward the user's face as the mask body 31 is deformed by the user's breathing. Here, in the guard body 2, sliding resistance is generated in the overlapping portion between the first guard portion 4 and the second guard portion 5 by the first annular portion 11a and the second annular portion 11b. It is necessary to slide the first guard portion 4 and the second guard portion 5 in the left-right direction against this sliding resistance. Therefore, even if the external force acts on the guard body 2, it is possible to easily prevent the first guard portion 4 and the second guard portion 5 from sliding inward in the left-right direction.

As shown in FIG. 11, the closed reversing spring portion 7 of the clip 3 is in a state along the cheek H of the user. Therefore, with the mask 30 attached, the gap between the left and right edges of the mask body 31 and the cheek H can be reduced.

Further, the mask auxiliary tool 1 of this embodiment can adjust the length of the guard body 2. Therefore, for example, as shown in FIG. 7B, it can be attached to the mask 30 for children whose length in the left-right direction of the mask body 31 is smaller than that of the mask 30 for adults. Further, after the mask 30 is used, the mask auxiliary tool 1 can be used again for another mask 30 replaced by the user by wiping each part with a cloth or the like soaked with a disinfectant solution or the like.

As shown in FIG. 12, the mask auxiliary tool 1 of this embodiment can be used for a three-dimensional mask 40 in which non-woven fabrics are spliced so as to have a bowl-shaped three-dimensional shape. The three-dimensional mask 40 has a non-woven fabric sheet on the right side that constitutes the right half of the mask body 41 and a left side that constitutes the left half of the mask body 41 through a seam that extends vertically at the center position of the user's face. It is a spliced piece of non-woven cloth sheet. Ear hooks 42 are integrally formed on the right and left non-woven fabric sheets of the mask body 41 on the outside in the left-right direction.

Clips 3 of the mask auxiliary tool 1 are attached to both ends of the mask body 41 of the three-dimensional mask 40 in the left-right direction. This attachment is the same as in the case of the mask 30 described above. The guard body 2 of the mask auxiliary tool 1 forms a gap between the mouth of the user and the mask body 41 of the three-dimensional mask 40. This gap can prevent the mask body 41 from sticking to the user's mouth due to the user's breathing.
