  • Both ends 25a and 25b of the central portion 25 are intersections of the contour line of the corner 24 that curves downward and the contour line that curves upward, and the length L4 of the central portion 25 is between the ends 25a and 25b. Means the length of the contour line that curves upward.
  • Both ends 25a and 25b of the central portion 25 are portions that are starting points in the width direction X of the central portion 25, and are lines that form the central portion 25 that protrudes upward and the corners 24 that protrude downward. Located at the intersection with the line forming the outline.

  • the length dimension when the central portion 25 extends linearly in the width direction X that is, both ends 25a and 25b are
  • the length dimension L4 is larger than the length dimension L5 of the virtual line K1 connected by a straight line.
  • the length dimension L4 of the central portion 25 is 110 to 133 mm, and the length About 5 to 8 mm longer than the dimension L5.
  • the transverse center line Q divides the size of the mask body 20 in the vertical direction Y into two equal parts.
  • the vertical dimension Y of the mask body 20 is not constant.
  • the transverse center line Q divides the separation dimension between the uppermost portion and the lowermost portion of the mask body 20 into two equal parts. It can be said that the vertical dimension Y of both side edges 20c, 20d extending in parallel is divided into two equal parts.
  • the lower end 22 of the mask body 20 is pulled downward to extend the plurality of collars 60.
  • the lower end 22 of the mask body 20 is pulled rearward by the ear hook 30 and the third and fourth collars 63 are in a state where both side portions of the fourth collar 64 are pressed against the wearer's skin. , 64 are pulled downward, so that the vertical dimension of the central area 14 is increased.
  • the extension area of the second collar part 62 and, optionally, the first collar part 61 is extended in order according to the longitudinal length of the face of the wearer. .
  • the lower end portion 22 of the mask main body 20 is mounted with the central portion 25 of the lower end edge 20 b extending substantially linearly in the width direction X in the extended state of the fourth collar portion 64. It touches the person's chin.
  • the central portion 25 of the lower edge 20b Extending downward from both side portions, that is, the vertical dimension of the central area 14 of the mask body 20 is larger than the vertical dimension of the both side areas 15, and the lower end part 22 of the mask body 20 is sufficient. There was a case where a gap was formed without fitting. Further, when the lower end portion 22 is further pulled in order to eliminate such doubling, it becomes close to the throat, which may cause discomfort particularly for a child wearer.
  • the lower end edge 20b of the mask main body 20 has the central portion 25 curved upward so that the vertical dimension of the central region 14 of the mask main body 20 is reduced before being extended. Since it is adjusted, the lower end portion 22b is fitted under the chin in a substantially straight state without the lower end portion 22 becoming stubble when extended and its vertical dimension is increased.
  • the lower end portion 22 when the shape of the central portion 25 of the lower end edge 20b is changed from a curved shape to a linear shape, the lower end portion 22 has a larger width dimension than the upper end portion 21 and the mouth and nose cover portion 23, and has spread laterally. The face is fitted in such a manner. Therefore, it can be said that the lower end portion 22 can be more stably fitted to the face by covering the wearer's lower jaw under a wide area at an appropriate position.

  • the vertical dimension can be adjusted as appropriate.
  • a part of the central portion 25 is located between the lower fixed ends 32 of the ear hooks 30. Is preferred. Since a part of the central portion 25 is located between the lower fixed ends 32, the curved portion including the central portion 25 located between the lower fixed end 32 pressed against the face as a starting point is effected downward. Can be pulled down.
  • the 3rd and 4th collar parts 63 and 64 as a lower collar part, and those vertical dimensions before extending (the vertical dimension of the 3rd collar part 63, and the vertical dimension of the 4th collar part 64)
  • the total dimension is 20 to 30 mm. Therefore, when the extension areas are completely extended, the total vertical dimension becomes 55 to 65 mm, and the wearer's jaw can be covered. Further, since the central portion 25 extending substantially linearly under the jaw is separated from the lower edge of the mandible by about 15 to 25 mm, the jaw portion can be stably covered and the lower end portion 22 can be stably covered. There is no discomfort that some bite into the throat.
  • the degree of curvature of the central portion 25 of the lower end edge 20b can be adjusted as appropriate depending on the vertical length of the wearer's face. For example, in the case of an adult mask, the face is longer than a child, It is not necessary to largely adjust the vertical dimension of the central area 14 after mounting, and the degree of curvature is smaller than that for children. For example, when the mask 10 is for a child and the dimension L5 of the imaginary line K1 is 105 to 125 mm, the vertical dimension of the central portion 25, that is, straight lines in the width direction X connecting both ends 25a and 25b of the central portion 25.
