  The details of the mask according to the present invention will be described with reference to the accompanying drawings.

<First Embodiment>
FIG. 1 is a perspective view showing the front side of the mask 1 of the first embodiment, and FIG. 2 is a perspective view showing the rear side of the mask 1. In these drawings, A indicates the vertical direction, B indicates the width direction orthogonal to the vertical direction A, and C indicates the front-rear direction orthogonal to the vertical direction A and the width direction B. A line PP is a center line that bisects the mask 1 in the width direction B. In the present invention, the front in the front-rear direction C means the direction from the back of the mask wearer to the face, and the back means the opposite direction, that is, the direction from the face to the back of the head.
The mask 1 is formed symmetrically about the center line PP, and has an inner surface D that faces the wearer's face and an outer surface E that is the opposite surface of the inner surface D.

  For example, the mask 1 is thrown away after being used once, and is hung on at least one of the covering portion 2 that covers the nostril and mouth of the wearer, and the head, neck, and ears of the wearer. A tightening string 3 that can be rotated is provided, a string holding member 4 that attaches the tightening string 3 to the covering portion 2 so as to be adjustable in length, a nose clip 5, and a chin rest pad 6.

The covering portion 2 is cup-shaped, and as an example, a nonwoven fabric of thermoplastic synthetic fiber, a laminate of the nonwoven fabric, a laminate of the nonwoven fabric and a net-like sheet made of thermoplastic synthetic resin, made of thermoplastic synthetic resin The foamed sheet can be obtained by thermoforming.
The covering portion 2 is at least partially breathable, and a portion of the covering portion 2 is capable of taking in inhalation of the wearer and discharging exhalation, and has a filter function for filtering the inhalation and exhalation. is doing. The coating | coated part 2 is provided with the center part 22 which protrudes toward the front, and the peripheral part 24 extended cyclically | annularly.
The peripheral portion 24 is a portion that comes into contact with the face of the wearer from the front when the mask is worn, and includes a lower edge portion 24a that can come into contact with the jaw portion of the face, and an upper edge that can come into contact with the nose portion Part 24b. An opening 25 is formed on the rear surface side of the peripheral portion 24 so that the nose portion and the mouth portion can enter and retreat.
In the preferred mask 1, when the peripheral portion 24 is in contact with the wearer's face, the center portion 22 is separated from the face and a space is formed between the wearer's nostril and mouth. And covering.

  The string holding member 4 has a base portion, and by interposing the base portion between sheet-like members such as a nonwoven fabric forming the covering portion 2, the inner surface D side and the outer surface E side of the covering portion 2 are provided. The base part is prevented from appearing, and the base part is prevented from contacting the wearer's face. The string holding member 4 in the illustrated example is formed of a thermoplastic synthetic resin.

The nose clip 5 is a conventional one, is attached to the outer surface E of the upper edge portion 24 b of the covering portion 2, and is located above the chin rest pad 6. The nose clip 5 is made of, for example, a plastic metal sheet piece such as aluminum or other plastic material, and can sandwich the nose from both sides in the width direction B.
When the mask 1 is worn, if the nose portion is sandwiched between the nose clips 5 from both sides in the width direction B, the covering portion 2 is shifted downward by the nose clip 5 even if the mouth moves when the wearer speaks. Can be prevented.

The chin pad 6 is formed of a sheet-like piece of thermoplastic synthetic resin such as nylon, polypropylene, soft polyethylene, or vinyl chloride, a piece of nonwoven fabric formed of thermoplastic synthetic fiber, or a piece of flexible foam sheet. It is a separate member from the covering portion 2.
The chin pad 6 has a pad inner surface 64 that faces the inner surface D of the covering portion 2, and a pad outer surface 65 that is the opposite surface of the pad inner surface 64.
The chin rest pad 6 is joined to the peripheral portion 24 at a portion where the pad inner surface 64 of the lower portion 61 overlaps the inner surface D of the peripheral portion 24, while the portions other than the lower portion 61 are attached to the covering portion 2. In a non-bonded state For example, the upper part 62 is not joined to the covering portion 2.
Further, the contour of the lower portion 61 of the chin pad 6 substantially coincides with the contour of the lower edge portion 24a of the covering portion 2 and forms a curve that is generally convex downward.
The contour of the upper portion 62 of the chin rest pad 6 is a curve that is generally convex upward, and the distance in the vertical direction A from the lower portion 61 is the largest at the portion that coincides with the center line PP. large. The distance between the upper portion 62 and the lower portion 61 gradually decreases with distance from the center line PP in the width direction B, and overlaps the lower edge portion 24a at the end portions 63 located on both sides in the width direction B. . Thus, the position of the chin pad 6 when the upper portion 62 is directed upward in the vertical direction A along the center line PP is referred to as a first position. When in the first position, the lower portion 61 and portions other than the lower portion 61 face the inner surface D of the covering portion 2.
3 is a view similar to FIG. 2 showing a state when the chin pad 6 is in the second position, and FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. The chin pad 6 is supported by the covering portion 2 at the lower portion 61, and the portions other than the lower portion 61 can reciprocate between the first position and the second position. When the chin pad 6 is moved from the first position to the second position, the portion other than the lower portion 61 changes in the front-rear direction C and extends below the jaw portion G. That is, when the chin pad 6 is in the second position, a portion other than the lower portion 61 that is not joined to the covering portion 2 extends below the chin portion.
The chin pad 6 is supported by the covering portion 2 via the lower portion 61 by integrating the lower portion 61 and the lower edge portion 24a of the covering portion 2 by, for example, thermal welding described later. . Further, the chin pad 6 is bent so as to turn as shown in FIGS. 3 and 4 along the portion where heat welding is performed, so that the portions other than the lower portion 61 are in the first position and the second position. Between them.

  In this mask 1, a plurality of fiber nonwoven fabrics, a string holding member 4, and a chin pad 6 are stacked and then pressed under heat to apply a cup-shaped covering portion 2 and a seal line 26 at a peripheral portion 24. And formed. In the seal line 26, the stacked members are in a welded state, and has higher rigidity than the central portion 22 of the covering portion 2.

It is desirable that the chin pad 6 is in the first position after the mask 1 is manufactured and worn. For example, when a plurality of masks 1 are put in one packaging bag, the masks 1 can be prevented from becoming bulky.
On the other hand, when the mask 1 is worn, when the chin pad 6 is in the second position, when the wearer's nostril and mouth are covered with the covering portion 2, the lower edge portion 24a of the covering portion 2 and the jaw portion are covered. The chin pad 6 extending below G can be brought into contact with the jaw G from below. In addition, the wearer's nose H can be sandwiched between the nose clips 5 from both sides in the width direction B.
In a state where the mask 1 is worn, a space 27 is formed between the covering portion 2 and the face F. Moreover, it can prevent that a clearance gap is made between the peripheral part 24 and the face by the seal line 26 which has rigidity higher than the center part 22 of the coating | coated part 2. FIG.

  According to the mask 1 formed in this way, the covering portion 2 can extend from the lower edge portion 24a to the lower side of the jaw portion G and contact the jaw portion G from below when the mask 1 is worn. Since a certain chin pad 6 is provided, the chin pad 6 is in contact with the jaw G even when the mouth moves due to the wearer's speaking or the like and the covering portion 2 tends to shift upward. The covering portion 2 can be prevented from shifting upward by the chin pad 6. Further, the nose clip 5 can prevent the covering portion 2 from moving upward. In the mask 1 when the chin pad 6 and the nose clip 5 cooperate, the covering portion 2 does not shift upward or downward with respect to the face.

In consideration of preventing the covering portion 2 from shifting upward, it is preferable that the contact area between the wearer's jaw G and the chin pad 6 is wide. Therefore, the seal line 26 is preferably formed as close to the lower portion 61 of the chin pad 6 as possible, as shown in FIG. Furthermore, the length dimension L1 in the vertical direction A of the chin pad 6 shown in FIG. 5 is more advantageous as it is longer.
On the other hand, considering the wearing state, if the length L1 is too long, the upper portion 62 of the chin pad 6 may come into contact with the wearer's throat, and the wearer may feel uncomfortable. The peripheral portion 26 may be lifted from the person's face F, and the airtightness of the space 27 may not be ensured.
Considering these, it is preferable to set the length dimension L1 of the chin pad 6 in the vertical direction A in the range of 20 mm to 60 mm.
Further, if the width dimension W1 of the chin pad 6 in the width direction B is too narrow, it cannot resist the movement of the mouth, and the covering portion 2 will be displaced upward, whereas if it is too wide, it is useless. Since a material is used, it is preferable to set in the range of 30 mm to 100 mm.
Furthermore, although the thickness dimension T1 (see FIG. 4) of the chin rest pad 6 depends on the material, it is difficult to swivel between the first position and the second position when the thickness dimension T1 is greater than a certain thickness. On the other hand, if it is below a certain thickness, it cannot resist the movement of the mouth. Although it depends on the nature of the sheet material used for the chin pad 6, the thickness dimension T1 is generally set in the range of 0.5 mm to 4.0 mm so that the rigidity becomes an appropriate value. It is preferable.

Note that the present invention is not limited to the above-described embodiment. For example, the shape of the chin pad 6 can be arbitrarily changed. The chin pad 6 may be formed as a sheet piece having elasticity such as synthetic rubber, or may be formed from a sponge-like sheet piece having air permeability and water absorption using polystyrene or the like as a material. Good. When the chin pad 6 is formed of an elastic sheet piece and the chin pad 6 is elastically abutted against the jaw G in FIG. Becomes higher.
Further, the chin pad 6 may be formed separately from the covering portion 2 or may be formed integrally.
Furthermore, although the chin pad 6 has been described as being joined to the covering portion 2 by the seal line 26, it may be joined to the covering portion 2 at a location different from the seal line 26.
Moreover, it is not necessary to make the shape of the lower part 61 of the chin pad 6 and the shape of the lower edge part 24a of the covering part 2 match, for example, from the lower edge part 24a of the covering part 2 The lower part 61 may protrude.
Further, it is not necessary to simultaneously integrate the chin pad 6, the covering portion 2, and the string holding member 4, and a part of the chin pad 6, the covering portion 2, and the string holding member 4 is integrated. After the conversion, the remaining part may be separately attached with an adhesive or the like. Of course, it may be attached individually.
Further, the attachment of the chin pad 6 to the covering portion 2 is not limited to the above-described heat welding, but may be ultrasonic welding or high-frequency welding. Of course, you may attach by another method.
Furthermore, the covering portion 2 may have a three-dimensional shape other than the cup shape of the illustrated example. Of course, the covering portion 2 may have a rectangular planar shape.
Further, the chin pad 6 is not limited to the one applied to the mask 1 described above, and may be applied to a mask having a portion that does not have air permeability in a part of the covering portion 2, an intake valve and an exhaust valve. You may apply to the mask which has at least one of a valve.

<Second Embodiment>
FIG. 6 is a perspective view showing the rear surface side of the mask 10 of the second embodiment. In the mask 10 of the second embodiment, members and parts having the same configuration, function, etc. as those of the mask 1 of the first embodiment are denoted by the same reference numerals and description thereof is omitted.

The covering portion 2 of the mask 10 has a cushion pad 7 that extends annularly along the peripheral portion 24 on the inner surface D of the peripheral portion 24, but the other members and portions are the same as the mask 1.
The cushion pad 7 is formed of, for example, a foamed sheet of thermoplastic synthetic resin, is flexible and elastically deformable, and is preferably non-breathable. The cushion pad 7 is prepared as a separate member from the chin pad 6.
The annular cushion pad 7 has an opening 71 formed inside thereof, and has a belt-like portion 72 extending along the peripheral portion 24 of the covering portion 2. The opening 71 is formed so that the vertical and horizontal sizes in the vertical direction A and the width direction B are smaller than the vertical and horizontal sizes of the opening 25 of the covering portion 2 shown in FIG. And the mouth portion have such a size that they can enter and retreat.
In this mask 10, the cushion pad 7 is attached to the covering portion 2, and the chin rest pad 6 is attached to the covering portion 2 via the cushion pad 7.

The cushion pad 7 includes a nose contact portion 73 on the center line PP in FIG. 6 so that the cushion pad 7 can easily fit around the nose portion H (see FIG. 4). The cushion pad 7 is cut out in an inverted V shape. The nose contact portion 73 moves downward from the covering portion 2 by the nose portion H coming into contact with the nose contact portion 73 even when the wearer moves his / her mouth to cause the covering portion 2 to shift downward. Can be prevented. Therefore, the covering portion 2 can be prevented from shifting in the vertical direction A by the nose contact portion 73 and the chin pad 6. In this mask 10, the nose clip 5 (see FIG. 1) is not provided because the cushion pad 7 has the nose contact portion 73.
The cushion pad 7 is integrated with the covering portion 2 by performing heat welding together with, for example, the fiber nonwoven fabric forming the covering portion 2 and the chin pad 6.

  As can be seen in FIG. 6, the chin pad 6 can be made so that the entire area thereof overlaps with the cushion pad 7 in a state where it is set at the first position similar to FIG. 2. In such a cushion pad 7, it is possible to prevent the upper portion 62 of the chin pad 6 from protruding from the cushion pad 7 to the opening 71.

  In such a mask 10, if the wearer does not want to use the chin rest pad 6 in the second position, the user can wear the mask 10 with the chin rest pad 6 set in the first position. Since the entire area of the abutting pad 6 overlaps the cushion pad 7, the upper portion 62 of the chin abutting pad 6 does not protrude into the opening 71. It will not get in the way.

  The present invention is not limited to the above-described embodiment, and various modifications similar to those in the first embodiment can be performed. For example, the cushion pad 7 does not need to be integrated with the covering portion 2 or the like by thermal welding, and may be attached to the covering portion 2 with an adhesive or the like, for example. Moreover, the cushion pad 7 and the chin pad 6 may be formed separately or integrally.

Moreover, an example of the aspect different from FIG. 6 about the mask 10 is shown in FIG. As shown in the drawing, the cushion pad 7 is formed with a notch 74 extending from the opening 71 toward the peripheral portion 24.
If the plurality of notches 74 are formed in the cushion pad 7 in this manner, the cushion pad 7 has further flexibility, and thus it is possible to reliably prevent a gap from being generated between the wearer's face and the cushion pad 7. can do.
Further, two notches 74 are formed, and these notches 74 and the end 63 in the width direction B of the chin pad 6 are substantially matched. Thus, if the notch 74 and the end 63 in the width direction B of the chin pad 6 are substantially matched, the mask 10 is worn with the portion other than the lower portion 61 moved to the first position. Since the cushion pad 7 that overlaps the chin pad 6 can be tilted forward by the notch 74, it is possible to prevent a gap from being generated between the wearer's face and the cushion pad 7. Can do.
