Hereinafter, embodiments of the mask auxiliary member 1 and the mask 100 will be described with reference to the drawings. The following embodiments are exemplary and the present disclosure is not limited to the configuration of the embodiments.

In the figure, the Y-axis indicates the outside of the mask 100, and the opposite direction indicates the inside of the mask 100, that is, the direction approaching the face of the wearer 103. The Z-axis indicates vertically downward, and the opposite direction indicates upward. The X-axis is orthogonal to the Y-axis and the Z-axis and indicates the width direction.

<First Embodiment>
As shown in FIG. 1, the mask 100 includes a fabric 105 that covers the mouth and nose of the wearer 103, and one or more (for example, two) straps 106. The fabric 105 may be made of, for example, non-woven fabric, cloth, or urethane.

As shown in FIG. 2, the fabric 105 has a hole 104 at a position corresponding to the mouth of the wearer 103. The mask auxiliary member 1 is attached to the mask 100, more specifically to the fabric 105, so as to cover the hole 104. The mask auxiliary member 1 may be detachably attached to the mask 100.

The mask auxiliary member 1 includes a peripheral wall 40, and at least one of a slit valve 43 and a one-way valve 70. The slit valve 43 and the one-way valve 70 are examples of an opening / closing body.

The peripheral wall 40 defines an opening that opens toward the outside and the inside of the mask 100. More specifically, the peripheral wall 40 defines a first opening 13 that opens toward the outside of the mask 100 and a second opening 23 that opens toward the inside of the mask 100. The shapes of the

openings

13 and 23 can be arbitrarily changed, and may be, for example, an annular shape or a rectangular shape.

The slit valve 43 is arranged so as to cover the first opening 13. The one-way valve 70 is arranged so as to cover the second opening 23. The slit valve 43 and the one-way valve 70 may be an elastic member having a notch (slit), or may be a film that can be flexed and displaced. Alternatively, the slit valve 43 and the one-way valve 70 may be a plurality of elastic bodies covering different regions of the

corresponding openings

13, 23.

The slit valve 43 and the one-way valve 70 may have, for example, a plurality of slits extending in the radial direction from the center. The shape of the slit may be, for example, an asterisk, a cross, a single letter, a U-shape, or a V-shape. The slit valve 43 and the one-way valve 70 may be made of the same material or may be made of different materials.

The mask auxiliary member 1 may include a first flange 41 arranged at the first end of the peripheral wall 40 and a second flange 42 arranged at the second end of the peripheral wall 40. When the first flange 41 is arranged outside the fabric 105, the second flange 42 is arranged inside the fabric 105.

At least two of the peripheral wall 40, the first flange 41, or the slit valve 43 may be integrally formed. At least two of the peripheral wall 40, the second flange 42, or the one-way valve 70 may be integrally formed.

By combining a plurality of parts that were not integrally formed with each other, the assembly shown in FIG. 2 can be obtained. At the time of this combination, it is preferable to arrange the fabric 105 between the first flange 41 and the second flange 42. The slit valve 43 and the one-way valve 70 may be detachably attached to other members.

Next, the operation of the first embodiment will be described.

The slit valve 43 and the one-way valve 70 are configured to be opened by pressing a peripheral wall 40, i.e., an insert 101 capable of passing through the first opening 13 and the second opening 23, such as a straw, a mouthpiece or a cup. As a result, the mask auxiliary member 1 allows the insertion object 101 to pass through. The slit valve 43 and the one-way valve 70 opened by the insert 101 return to their original positions when the insert 101 is pulled out. Therefore, the slit valve 43 and the one-way valve 70 can be opened and closed by the operation of inserting and removing the insert 101 without performing an operation for opening and closing.

The one-way valve 70 opens by a force acting from the first opening 13 toward the second opening 23, and closes by a force acting from the second opening 23 toward the first opening 13. Therefore, the exhalation of the wearer 103, that is, the airflow outward from the wearer 103 is obstructed by the one-way valve 70. Specifically, since the one-way valve 70 is closed by the outward airflow, the second opening 23 is closed.

The effects of the first embodiment will be described below.

(1-1) The wearer 103 of the mask 100 can reach the insert 101 near the mouth through the slit valve 43 and the one-way valve 70. As a result, the wearer 103 can drink the beverage 102 while wearing the mask 100.

(1-2) Since the one-way valve 70 closes the second opening 23 by the exhalation of the wearer 103, the airflow in the mask 100 passes through the

openings

23 and 13 and is unlikely to flow out.

(1-3) The

flanges

41 and 42 can suppress the mask auxiliary member 1 from falling off from the mask 100, and can also suppress the flow of airflow through the hole 104 and the peripheral wall 40.

(1-4) By assembling the mask auxiliary member 1 so as to sandwich the mask 100 between the

flanges

41 and 42, the mask auxiliary member 1 can be easily attached to and detached from the mask 100.

(1-5) By making at least one of the slit valve 43 and the one-way valve 70 removable, when the

valves

43 and 70 become dirty or broken, they can be easily removed and cleaned or replaced.

In the following description of the embodiment, the same reference numerals are given to the same configurations as those of the first embodiment, and the description of their actions and effects will be omitted. The configurations included in the first embodiment and the configurations included in the embodiments described below can be combined with each other as long as they are not technically inconsistent.

<Second Embodiment>
As shown in FIGS. 3 to 5, the mask auxiliary member 1 according to the second embodiment includes an annular first member 10, an annular second member 20, and a disk-shaped first elastic member 11. A disk-shaped second elastic member 21 is provided. The first elastic member 11 is a valve body of the slit valve 43. The first elastic member 11 has a notch (slit) 12 through which the insert 101 can pass. The first member 10 and the second member 20 are made of, for example, resin. The

elastic members

11 and 21 may be made of rubber or urethane, for example.

As shown in FIG. 5, the first member 10 has a first opening 13 through which the insert 101 can pass, and a first flange 41 arranged outside the mask 100. The second member 20 has a peripheral wall 40 and a second flange 42. The second flange 42 is arranged so as to sandwich the fabric 105 with the first member 10.

As shown in FIG. 5, the circular first opening 13 penetrates the central portion of the first member 10. The first elastic member 11 is attached to the outer surface of the first member 10 so as to cover the first opening 13. When the wearer 103 presses the insert 101 against the notch 12 from the outside of the first elastic member 11, the first elastic member 11 is elastically deformed, and the insert 101 can enter the first opening 13. Become.

The second member 20 has a second opening 23 through which the insert 101 can pass. The second opening 23 penetrates the central portion of the second member 20. The notch 12 is, for example, cross-shaped, and its center may coincide with the center 45 of the second opening 23. The second member 20 has a mounting surface 22 above the center 45.

The second elastic member 21 may be attached to the mounting surface 22 so as to cover the second opening 23. The upper part of the second elastic member 21 is a fixed end, and the lower part is a free end. Therefore, when the insert 101 pushes the second elastic member 21 from the outside, the portion of the second elastic member 21 that is not attached to the attachment surface 22 is elastically deformed. The portion elastically deformed at this time is the valve body of the one-way valve 70 arranged so as to open and close the second opening 23.

The first member 10 has an annular protrusion 14 that protrudes toward the second member 20. The second member 20 has an annular engaging groove 24 on its outer surface. When the protrusion 14 engages with the engaging groove 24, the mask auxiliary member 1 is detachably attached to the mask 100 with the cloth 105 sandwiched between the first member 10 and the second member 20.

The tip of the protrusion 14 may be sharpened to form an acute angle. The tip of the protrusion 14 may be inclined from the outer peripheral edge of the first member 10 toward the inner peripheral edge, for example. For example, by sandwiching the non-woven fabric 105 between the protrusion 14 and the engaging groove 24, a part of the cloth 105 may be cut out in a circular shape by the tip of the protrusion 14. As a result, a circular hole 104 (see FIG. 2) is formed in the fabric 105. That is, the inclination of the tip is preferably an angle at which the fabric 105 can be cut out.

The fabric cut out at the tip of the protrusion 14 can be taken out through the first opening 13 or the second opening 23. However, the cut fabric may be taken out after removing the first member 10 from the second member 20. Instead of this, a tool different from the mask auxiliary member 1 may be used to make a hole 104 in the cloth 105 before mounting the mask auxiliary member 1.

The operation of the mask auxiliary member 1 of the second embodiment will be described.

FIG. 6 shows a state in which the insert 101 penetrates the fabric 105 through the mask auxiliary member 1. When the tip of the insert 101 is inserted into the notch 12 of the first elastic member 11, the insert 101 passes through the notch 12 and the

openings

13 and 23 and reaches the second elastic member 21. Then, when the insert 101 pushes the second elastic member 21, the lower portion of the second elastic member 21 is turned up. As a result, the tip of the insert 101 reaches the mouth of the wearer 103. As a result, the wearer 103 can drink the beverage 102 (see FIG. 1) while wearing the mask 100.

FIG. 7 explains that the second elastic member 21 functions as a check valve for the exhaled breath of the wearer 103. The second elastic member 21 obstructs the exhalation of the wearer 103, that is, the flow of gas outward from the wearer 103. Specifically, the second elastic member 21 is pressed against the second member 20 by the outward airflow, and the second opening 23 is closed by the second elastic member 21. Therefore, the airflow in the mask 100 does not easily flow out through the

openings

23 and 13.

According to the second embodiment, the following effects can be obtained in addition to the effects of the above embodiment.

(2-1) A hole 104 can be made in the fabric 105 by the protrusion 14 and the engaging groove 24.

<First modification of the second embodiment>
As in the first modification shown in FIG. 8, the first elastic member 11 may be arranged between the outer surface of the first member 10 and the inner surface of the first member 10. The first elastic member 11 may be integrally formed with the first member 10. Again, the insert 101 can pass through the first opening 13 through the notch 12.

The upper portion of the second elastic member 21 may be arranged between the outer surface of the second member 20 and the inner surface of the second member 20. The second elastic member 21 may be integrally formed with the second member 20. Even in this case, the lower portion of the second elastic member 21 may be a free end.

<Second variant of the second embodiment>
The shape of the protrusion 14 may be changed as in the second modification shown in FIG. For example, the tip of the protrusion 14 may be inclined toward the center from the outer peripheral edge and the inner peripheral edge of the first member 10.

The mask auxiliary member 1 of the second modification can be suitably used for a gauze type mask on which cotton fabrics are laminated. In this case, it is advisable to make a hole 104 in the vicinity of the mouth of the cloth 105 in advance and attach the mask auxiliary member 1 to the mask 100 so as to sandwich the hole 104.

<Third Embodiment>
As shown in FIG. 10, the mask auxiliary member 1 of the third embodiment includes a first member 10, a second member 20, a first elastic member 11, and a second elastic member 21. The first member 10 has a first flange 41, a first opening 13, and a female screw which is a groove 24. The second member 20 includes a second flange 42, a peripheral wall 40, and a second opening 23. The peripheral wall 40 is also a protrusion 14, and the protrusion 14 is also a male screw.

The first elastic member 11 may have an engaging flange 15, an inner peripheral surface 17, and a fixing surface 18 that comes into contact with the second elastic member 21. The fixing surface 18 is a tip surface (right end surface in FIG. 10) of the engaging flange 15. The inner peripheral surface 17 may be inclined in a conical shape so that the diameter increases from the stop surface 18 toward the first opening 13. By inclining the inner peripheral surface 17 in this way, the area of the stop surface 18 can be increased. Further, the inclination of the inner peripheral surface 17 allows the insert 101 to be guided from the first opening 13 toward the second opening 23.

The second elastic member 21 may have an engaging rim 25 that engages with the engaging flange 15. The first elastic member 11 and the second elastic member 21 are housed on the inner peripheral side of the peripheral wall 40 in a state where the engaging flange 15 and the engaging rim 25 are engaged with each other. The material of the

elastic members

11 and 21 is, for example, silicon or an elastomer.

As shown in FIGS. 11 and 12, the first elastic member 11 is a slit valve 43 and has a cross-shaped notch 12. The second elastic member 21 has a U-shaped notch 26. The U-shaped tongue piece of the second elastic member 21 defined by the notch 26 is the valve body 28 of the one-way valve 70.

As shown in FIG. 11, the first member 10 or the first flange 41 may have a non-slip 19. The non-slip 19 is, for example, a plurality of protrusions arranged along the circumferential direction. The second member 20 or the second flange 42 may have a handle portion 27 that can be grasped by a finger. The handle portion 27 is, for example, a plurality of recesses arranged along the outer edge of the second flange 42.

The mask auxiliary member 1 may include a decorative member 50 arranged between the first flange 41 and the second flange 42. The decorative member 50 has a through hole 51 through which the peripheral wall 40 can penetrate. The decorative member 50 may have one or more (for example, three) receiving portions 52 arranged along the through hole 51.

As shown in FIG. 12, the decorative member 50 may have a plurality of protrusions 53 arranged along the through hole 51. The convex portion 53 projects from the inner surface of the decorative member 50, that is, the surface facing the second member 20, toward the second member 20. The convex portion 53 may have, for example, a sharp tip.

The decorative member 50 can have, for example, any shape, color, material, pattern, or color that imitates the shape of an animal or character. A seal, a label, or another decorative part (eg, metal part, fur, or silicon, etc.) may be attached to the decorative member 50. Alternatively or additionally, the decorative member 50 may have an area on which characters or illustrations can be drawn.

The first member 10 may have one or more (for example, three) positioning portions 16 arranged so as to engage with the receiving portion 52. When the receiving portion 52 is a notch or a recess, the positioning portion 16 may be a protrusion protruding toward the decorative member 50. When the receiving portion 52 is a protrusion, the positioning portion 16 may be a notch or a recess.

Next, the operation of the third embodiment will be described.

When attaching the mask auxiliary member 1 to the mask 100, first, the

elastic members

11 and 21 are housed on the inner peripheral side of the peripheral wall 40. Next, the peripheral wall 40 of the second member 20 is passed through the hole 104 of the mask 100. Then, the male screw of the protrusion 14 is screwed into the female screw of the groove 24. As a result, the first member 10, the second member 20, the first elastic member 11, and the second elastic member 21 are integrally combined. At the same time, the mask auxiliary member 1 is attached to the mask 100.

When the decorative member 50 is added to the mask auxiliary member 1, the decorative member 50 is engaged with the first member 10 before the first member 10 is combined with the second member 20. More specifically, by engaging the receiving portion 52 and the positioning portion 16, the decorative member 50 is arranged in an appropriate direction with respect to the first member 10. Then, after passing the peripheral wall 40 through the hole 104, the peripheral wall 40 is passed through the through hole 51 of the decorative member 50, and the male screw of the protrusion 14 is screwed into the female screw of the groove 24. As a result, when the decorative member 50 sandwiches the first member 10 with the second member 20, the plurality of convex portions 53 of the decorative member 50 come into contact with the flat surface which is the outer surface of the second flange 42.

The first member 10 and the second member 20 can be easily removed from the mask 100 by loosening the male screw and the female screw. Therefore, the decorative member 50, the first elastic member 11 (slit valve 43), and the second elastic member 21 (one-way valve 70) can be easily replaced.

The valve body 28 opens when pushed by the insert 101 that has passed through the notch 12, and returns to its original position when the insert 101 is pulled out. Further, when the exhaled breath of the wearer 103 hits the valve body 28, the valve body 28 is pressed against the stop surface 18. As a result, the second opening 23 is closed.

According to the third embodiment, the following effects can be obtained in addition to the effects of the above embodiment.

(3-1) With the decorative member 50, the mask 100 can be decorated according to personal preference.

(3-2) By engaging the positioning portion 16 with the receiving portion 52, the decorative member 50 can be correctly positioned with respect to the first member 10 according to the design of the decorative member 50.

(3-3) By adjusting the tightening method of the protrusion 14 (male screw) with respect to the groove 24 (female screw), the distance between the first flange 41 and the second flange 42 can be adjusted according to the thickness of the decorative member 50. Can be adjusted. At this time, since there is a handle portion 27 and a non-slip portion 19, the screws can be easily tightened.

(3-4) When the plurality of convex portions 53 come into contact with the second flange 42, the frictional resistance when the decorative member 50 and the second member 20 come into contact with each other increases. Therefore, the decorative member 50 can be firmly fixed to the second member 20.

<Fourth Embodiment>
As shown in FIGS. 13 to 16, the mask auxiliary member 1 of the fourth embodiment includes a first member 10, a second member 20, and a spacer 60. The first member 10 has a first flange 41, a slit valve 43, and a groove 24. The slit valve 43 has, for example, a cross-shaped notch 12.

The second member 20 has a second flange 42, a protrusion 14, a peripheral wall 40, and a one-way valve 70. The peripheral wall 40 has an annular protrusion 14 that protrudes outward in the radial direction of the second member 20 from one end thereof (the end outside the mask 100). The opening of the peripheral wall 40 and the outer shapes of the

flanges

41 and 42 may be rectangular. The one-way valve 70 is, for example, a Duckbill valve, which has two

inclined walls

71 and 72 and a linear notch 73.

The spacer 60 has a first frame 61, a plurality of (for example, four) arms 62, and a second frame 63. Each arm 62 has a first end connected to the first frame 61 and a second end connected to the second frame 63. The first frame 61 has a shape along the peripheral wall 40. The spacer 60, particularly the plurality of arms 62, is elastically deformable.

The peripheral wall 40 is inserted into the first frame 61. The second frame 63 may have a shape that follows the shape of the wearer 103's face, such as the nose and cheeks, inside the fabric 105. The spacer 60 defines a space between the fabric 105 and the mouth of the wearer 103. The duckbill valve, which is the one-way valve 70, is housed in this space.

Next, the operation of the fourth embodiment will be described.

When the mask auxiliary member 1 is attached to the mask 100, the protrusion 14 is elastically deformed, and the protrusion 14 and the peripheral wall 40 are inserted into the first frame 61. As a result, the spacer 60 and the second member 20 are combined. Next, the protrusion 14 is elastically deformed and the peripheral wall 40 is passed through the hole 104 of the fabric 105. After that, when the protrusion 14 is elastically deformed and engaged with the groove 24, the mask auxiliary member 1 is detachably attached to the mask. The mask auxiliary member 1 can be easily removed from the mask 100 by elastically deforming the protrusion 14 as in the case of mounting.

When the wearer 103 presses a container containing a beverage, for example, a cup (insertion 101) against the slit valve 43, the cup enters the inside of the peripheral wall 40 through the notch 12. Further, when the wearer 103 brings the cup closer to the mouth, the cup is guided by the

inclined walls

71 and 72 and approaches the notch 73. At this time, the arm 62 is elastically deformed by the pressing, the

inclined walls

71 and 72 approach the wearer 103 together with the cup, and the notch 73 reaches the mouth of the wearer 103.

According to the fourth embodiment, the following effects can be obtained in addition to the effects of the above embodiment.

(4-1) Due to the space defined by the spacer 60, the fabric 105 and the one-way valve 70 are less likely to come into contact with the wearer 103.

(4-2) The wearer 103 can drink a beverage from a cup or a mouthpiece through a notch 73 while wearing the mask 100.

<Fifth Embodiment>
As shown in FIGS. 17 to 20, the fifth embodiment differs from the fourth embodiment in that the frontal shapes of the

flanges

41, 42 and the

frames

61, 63 are generally circular. Since the mask auxiliary member 1 of the fifth embodiment has substantially the same configuration as that of the fourth embodiment, other explanations will be omitted.
