Description

  The present invention relates to a mask assisting tool used to keep a mask body from bulging.

  Conventionally, in order to eliminate the difficulty of breathing that is felt when the mask body's inflated part is sucked into the wearer's mouth and nose by inhalation of the mask wearer, the inner part of the mask body (the wearer's mouth and There is known a mask assisting device that is attached between the nose and the mask body to keep the mask body bulging.

  As this type of mask auxiliary tool, Patent Document 1 describes a mask holding tool in which an oval thin plate made of polypropylene is curved in an arch shape together with a mask body, and both end portions thereof are fixed to both side edges of the mask body. Has been. Patent Document 2 describes a mask pad for applying a trapezoidal cross-shaped patch having an opening made of paper or plastic to the wearer's mouth wearing a mask. Patent Document 3 is a mask auxiliary tool made of plastic, and includes a frame main body that curves along the wearer's nose column, and an extending portion that extends from the frame main body to a position corresponding to the mouth of the wearer. The thing comprised by is described.

JP 2003-93528 A JP 2000-271239 A JP 2011-244858 A

  However, for example, the mask shaper described in Patent Document 1 has a structure in which an oval thin plate is simply bent and attached to the mask body. Therefore, when pressure is applied to the mask body from the outside, both end portions are Since it is easily displaced laterally outward together with the mask body, there is a problem that the bulge of the mask body tends to collapse (that is, it is difficult to maintain the three-dimensional shape of the mask body).

  Further, for example, the mask applicator described in Patent Document 2 has a structure in which an object fixed in a trapezoidal cross section is simply applied to the mouth, so that the three-dimensional shape of the mask body can be easily maintained, but the wearer moves the mouth. In that case, it is difficult to follow and displace, so the wearer feels uncomfortable (that is, uncomfortable wearing), and the cost for molding into a trapezoidal section in the first place is relatively high. There was a problem.

  Further, for example, in the mask assisting device described in Patent Document 3, since the structure is such that the curved frame main body is merely applied to the wearer's nose column, there are few contact portions between the mask main body and the frame main body. Since the force urged to the frame body is weak, there is a problem that the frame body easily slips off the wearer's nose column (that is, the frame body cannot be fixed to the nose column well).

  The present invention has been made in view of the above-mentioned problems and the like, and can provide a mask auxiliary tool that can more suitably keep the bulge of the mask body without impairing the wearer's feeling of use, and is advantageous in terms of cost. With the goal.

  The present invention made in order to achieve the above object is a mask auxiliary tool used for keeping the mask body bulging, and a plurality of first curvatures curved along the surrounding skin of the wearer of the mask body. And a second bending portion that is supported at both ends by a connecting portion that connects the ends of the plurality of first bending portions and is bent in the direction of the mask body. In the present invention, the first bending portion and the second bending portion are formed of a single sheet having flexibility, and each has a different radius of curvature corresponding to the contact object by cutting the sheet. Is formed.

  In the mask assisting device configured as described above, the second bending portion that is bent along the mask body is supported by the plurality of first bending portions that are bent along the surrounding skin. Even when pressure is applied from the outside, both end portions of the second curved portion are not easily displaced in the lateral direction, so that the three-dimensional shape is easily maintained (that is, the bulge of the mask body is difficult to collapse). .

  In addition, since the first bending portion and the second bending portion are separately arranged by cutting a single sheet having flexibility, even if the wearer moves his / her mouth, it follows. Since it becomes easy to displace (has flexibility), it is possible to improve the wearer's feeling of use (that is, to reduce the wearer's uncomfortable feeling), and it is formed from a single sheet, so the cost Can be suppressed.

  Furthermore, the first bending portion and the second bending portion have a radius of curvature such that the first bending portion contacts the surrounding skin of the wearer while the second bending portion contacts the mask body. By setting, the second curved portion is urged from the mask body, and the first curved portion is urged from the surrounding skin (skin around the wearer's mouth). The tool can be suitably fixed to the inner part of the mask body (between the wearer's surrounding skin and the mask body).

  Therefore, according to the configuration of the present invention, it is possible to more suitably keep the swell of the mask body without impairing the wearer's feeling of use, and it is possible to provide a mask auxiliary tool that is advantageous in terms of cost.

  If the plurality of first curved portions are in contact with the surrounding skin of the wearer and support the second curved portion at the connecting portion on the end portion side, the shape and arrangement of the first curved portions are not limited. Although it does not ask | require, it is good to form the opening part larger than a wearer's mouth, for example in the part which contacts a surrounding skin. According to such a configuration, even when the wearer moves his / her mouth, the use feeling can be further improved because the wearer hardly disturbs the wearer.

  In addition, the second bending portion may be in any shape and arrangement as long as both ends thereof are supported by the connecting portion of the first bending portion in contact with the mask body. It is good to arrange | position in the position corresponding between a person's mouth and nose. According to such a configuration, since the space between the wearer's nose and the mask body is held by the second curved portion, the mask body is not sucked into the wearer's nasal cavity, The difficulty of breathing when wearing a mask can be suitably mitigated.

  Further, for example, the second bending portion has a main bending portion that curves along the lateral bulge of the mask main body, and an extending portion that extends from the main bending portion in the vertical direction of the mask main body. Also good. In this case, the contact area between the second curved portion and the mask main body can be increased, and when the pressure is applied to the mask main body from the outside, the applied force can be dispersed. Since it becomes easier to maintain the shape, the bulge of the mask body can be more suitably maintained.

  Further, for example, the second bending portion may have an opening at a position corresponding to the wearer's mouth. According to such a configuration, the wearer's feeling of use can be further improved because the second bending portion can be prevented from vibrating due to sound when the wearer speaks.

  By the way, the first bending portion is configured such that the second bending portion has a smaller radius of curvature than the first bending portion by inserting one of the two members separated into the left and right by the sheet cutting into the other. You may have the insertion structure curved. In this case, for example, it is possible to manufacture, transport, and sell a single sheet having a notch, and to assemble it by a simple operation (insertion) of the wearer. Can be reduced.

  In addition, the second bending portion has a mouth-nose position bending portion that is arranged at a position corresponding to between the mouth and nose of the wearer and curves along the lateral bulge of the mask body. The curved portion may be formed such that the vertical width of the central portion is smaller than the vertical width of both side portions. In this case, in the mouth-nose position curved portion, the central portion having a small vertical width is easier to bend than the both side portions having a large vertical width, so that a bulge corresponding to the space between the wearer's nose and the mask body is provided. It can form more suitably.

  Similarly, the second curved portion has a nose position curved portion that is arranged at a position corresponding to the wearer's nose and curves along the lateral bulge of the mask body. The vertical width of the central portion may be formed smaller than the vertical width of both side portions thereof. In this case, in the nose position bending portion, the central portion having a small vertical width is easier to bend than the both side portions having a large vertical width, so that a bulge according to the shape of the wearer's nose can be formed more suitably.

Both end portions of the curved portion 200 are less likely to be displaced laterally. Thereby, it becomes easy to maintain the three-dimensional shape of the mask auxiliary tool 1, and as a result, the bulge of the mask main body 2a becomes difficult to collapse. In addition, since the length between the support points A and B does not change, the contact between the mask auxiliary tool 1 and the wearer does not change, so that the wear feeling of the mask auxiliary tool 1 is not impaired and the wearer is less likely to feel uncomfortable. be able to.

<Effects common to the first embodiment and the second embodiment>
As described above, the mask auxiliary tool 1 (100) includes a plurality (two) of the first curved portions 10 that are curved along the surrounding skin of the wearer 3 of the mask 2, and a plurality (two) of the plurality of (two). Both ends are supported by a connecting portion (cheek rest portion 30) that connects the end portions of the first bending portion 10, and a second bending portion 20 (200) that curves in the direction of the mask body 2a is provided. And the 1st bending part 10 and the 2nd bending part 20 (200) consist of the sheet | seat 1a which has flexibility, and each has a different curvature radius according to the contact object by cutting of the sheet | seat 1a. It is formed to have.

  In the mask assisting tool 1 (100) configured as described above, the second bending portion 20 (200) that curves along the mask body 2a has a plurality (two) of first curves that curve along the surrounding skin. Since both end portions of the second bending portion 20 (200) are less likely to be laterally displaced even when pressure is applied to the mask body 2a from the outside, the second bending portion 20 (200) is less likely to be displaced laterally. It becomes easy to maintain the three-dimensional shape (that is, the bulge of the mask body 2a is less likely to collapse).

  Moreover, since the 1st curved part 10 and the 2nd curved part 20 (200) are divided | segmented and arrange | positioned by the notch | incision of the sheet | seat 1a which has flexibility, when the wearer 3 moves a mouth, Even if it exists, since it becomes easy to follow and to displace (it has flexibility), it becomes possible to improve the feeling of use of the wearer 3 (that is, to reduce the discomfort of the wearer 3). Since the sheet 1a is formed, the cost can be suppressed.

  Furthermore, while the 1st bending part 10 contacts the surrounding skin of the wearer 3, the 1st bending part 10 and the 1st bending part 20 (200) contact the mask main body 2a. By setting the curvature radius of the second curved portion 20 (200), the second curved portion 20 (200) is urged from the mask body 2a, and the surrounding skin (around the wearer's mouth) Since the first bending portion 10 is biased from the skin), the mask auxiliary tool 1 (100) is suitably fixed to the inner part of the mask body 2a (between the surrounding skin of the wearer 3 and the mask body 2a). It becomes possible to do.

  Therefore, according to the configuration of the mask auxiliary tool 1 (100), the swelling of the mask main body 2a can be more suitably maintained without impairing the feeling of use of the wearer 3, and an advantageous one from the viewpoint of cost is provided. be able to.

  Further, according to the configuration of the mask assisting tool 1 (100), the wear is achieved by increasing the contact area between the first curved portion 10 and the cheek rest portion 30 and the face of the wearer 3 (the surrounding skin). It is possible to prevent the person 3 from feeling uncomfortable as if piercing the skin. From this point of view, for example, the first bending portion 10 has a round shape such that the surface that comes into contact with the face of the wearer 3 (the surrounding skin) is convex toward the surrounding skin. You can also

  Further, in the mask assisting tool 1 (100), the first curved portion 10 and the cheek pad 30 are larger than the mouth of the wearer 3 (first opening 40a) in the portion that contacts the surrounding skin. ), Even when the wearer 3 moves his / her mouth, the portion of the cheek rest 30 in the first opening 40a is flexibly stretched and hardly gets in the way. Therefore, the feeling of use can be further improved (for example, not to get in the way when speaking). The sheet 1a may be any sheet having flexibility. For example, when importance is attached to durability, a material with less wear such as plastic may be used, or moisture such as sweat may be absorbed. Alternatively, a material having good absorbency such as Japanese paper may be used.

  Further, in the mask assisting tool 1 (100), the second curved portion 20 (200) is disposed at a position corresponding at least between the mouth and the nose of the wearer 3, so Since the space between the mask body 2a and the mask body 2a is maintained, the mask body 2a is not sucked into the wearer's nasal cavity, and the breathing difficulty in wearing the mask can be preferably alleviated. Specifically, for example, it is possible to eliminate the breathing difficulty of the wearer 3 when sleeping at night, and to provide the wearer 3 with ease of spending even in the pollen season and dust environment. Note that the breathing difficulty of the wearer 3 means that, for example, when the mask 2 is worn, the mask 2 sticks to the face of the wearer 3 by inhalation, and only a part of the area of the mask 2 at the nose or mouth hole is filtered. This is due to not functioning.
