Description

  The present invention relates to an improvement of a sanitary mask.

  A general sanitary mask is provided with a pair of ear straps on the side edge of the mask body. FIG. 8 is a diagram showing a state when the most general sanitary mask 200 is worn. The sanitary mask 200 is mounted by placing a pair of ear straps 40 on the left and right edges of the mask body 10 that covers the mouth and nostril, and by hanging these ear straps 40 on the ears of the wearer. If such a sanitary mask 200 is worn for a long time, there is a problem in that the ear of the wearer is likely to be painful. In order to eliminate the gap between the mask body 10 and the wearer's face, it is necessary to shorten the ear strap 40 and increase the pulling force backward, but ear pain is more likely to occur. There was a problem of becoming.

  In view of this, a sanitary mask mounting method for mounting the ear straps 40 without putting them on the ears has been proposed (Patent Document 2). FIG. 9 is a diagram showing a method of wearing the sanitary mask 201 described in Patent Document 2. As shown in FIG. The mounting method described in Patent Document 2 is a method in which the ear straps 40 of Patent Document 1 are disposed below the ears, and the left and right ear straps 40 are connected to each other by an auxiliary tool 41 disposed at the back of the neck. . Since this mounting method is a method in which the ear hooking portion 40 is not put on the ear, it is possible to prevent the ear from being painful. However, since the ear strap 40 is disposed below the ear, a downward downward force is applied to the mask main body 10. For this reason, there is a problem that the mask main body portion 10 cannot be satisfactorily fitted to the wearer's face, a gap is easily generated, and the mask main body portion 10 is easily dropped.

  Further, a mask that fits the mask main body 10 satisfactorily by attaching a wide belt to the head is known (for example, Patent Document 2). However, since a general sanitary mask is disposable, a string member having flexibility and stretchability, for example, a rubber string is used. Considering the cost, instead of such a simple string, a wide band is used. There was a problem that the belt could not be adopted.

Preventing direct contact with outside air.

  The pleat 11 is a pleated portion that is partially overlapped by folding the cloth of the mask main body 10 in a mountain fold and a valley fold. The mask body portion 10 is provided with a plurality of pleats 11 extending in the left-right direction. While the pleat 11 is fixed so that the overlapping region does not open at the left and right ends, the overlapping region is not fixed at the center, and the overlap is achieved by applying an external force in the front-rear direction or a vertical tension. The area opens, and the mask main body 10 has a substantially bowl-shaped three-dimensional shape. For example, the mask body 10 before mounting has a substantially rectangular planar shape, and after mounting, a pressing force in the front-rear direction is applied by the nasal head or the chin, or vertical tension is applied by the support unit 2. In addition, it deforms and becomes a three-dimensional shape that fits the wearer's face.

  The shape holding plate 12 is an elongated metal plate extending in the left-right direction, and is attached in the vicinity of the upper edge of the mask main body 10. The shape retaining plate 12 is a metal plate that can be easily bent by the pressing force of a finger. When the sanitary mask 100 is worn, if the upper edge of the mask body 10 is pressed against the wearer's nose with the finger, It can be transformed into a shape that fits the shape. The shape of the shape holding plate 12 is maintained at least during wearing, and the gap between the mask main body 10 and the nose is reduced.

[Supporting part 2]
The support portions 2 are attached to the left and right side edge portions of the mask main body portion 10, respectively. For the support part 2, a string-shaped material having flexibility and stretchability, for example, a rubber string is used.

As shown in FIG. 3, the adjusting unit 21 according to the present embodiment separates the support unit 2 into two string members, provides a knot on one string member, and passes the other string member through the knot. Thus, the adjusting portion 21 is formed. If such an adjustment part 21 is employ | adopted, the length of the support part 2 can be adjusted, without adding a new component, and manufacturing cost can be suppressed.

  As for the said adjustment part 21, the front-end | tip of said one string member becomes the operation element 22 (pull), and when the wearer pulls the said operation element 22, the support part 2 becomes short. On the other hand, when no external force is applied, the length of the support portion 2 is maintained by the frictional force between the two string members. If the support portion 2 is configured to be shortened by pulling the operating element 22, it is desirable that the support portion 2 can be easily shortened even in the mounted state. In addition, the adjustment part 21 is not limited to such a structure, For example, it can also implement | achieve using a resin molded product. Moreover, if the length adjustment of the support part 2 is unnecessary, the adjustment part 21 can be omitted.

[Mounting part 3]
The mounting portion 3 is a connecting means for connecting the right support portion 20R and the left support portion 20L to each other, and the mask main body portion 10 is mounted on the human body by turning around the wearer's neck. For the mounting portion 3, a string-shaped material having flexibility and stretchability, for example, a rubber string is used. The mounting portion 3 has one end connected to the right support portion 20R and the other end connected to the left support portion 20L. The mounting unit 3 includes a right mounting unit 30R, a left mounting unit 30L, and a detachable unit 31.

  The right attachment part 30R is a string-like member (right attachment string) whose one end is connected to the right support part 20R and the other end is connected to the detachable part 31, and it is desirable to use a material having flexibility and stretchability. . The right mounting portion 30R is slidably connected to the right support portion 20R, and the connecting position thereof can move on the right support portion 20R. The right mounting portion 30R according to the present embodiment has an annular shape, and the right support portion 20R passes inside the annular shape. That is, the right mounting portion 30R is connected to the right support portion 20R in a chain shape.

  Similarly, the left attachment part 30L is a string-like member (left attachment string) having one end connected to the left support part 20L and the other end connected to the detachable part 31. The left mounting portion 30L is slidably connected to the left support portion 20L, and the connection position can move on the left support portion 20L. The left mounting portion 30L according to the present embodiment has an annular shape and is connected to the right support portion 20R in a chain shape.

  The detachable portion 31 connects the right mounting portion 30R and the left mounting portion 30L so as to be detachable. Although the detachable part 31 according to the present embodiment is made of a resin molded product provided with hooks on both sides, the detachable part 31 is not limited to such a configuration.

  FIG. 4 is a view showing an example of a state when the sanitary mask 100 of FIG. 1 is worn, and a view seen from the left side of the wearer. In addition, since the state at the time of attachment is left-right symmetric, the figure seen from the right side is abbreviate | omitted.

  The wearing portion 3 is connected to the support portion 2 in front of the wearer's ear, extends substantially horizontally through the lower portion of the wearer's ear, and is disposed so as to wrap around the back of the wearer's neck. That is, the attaching / detaching portion 31 is disposed behind the neck, the right mounting portion 30R is disposed below the right ear, and the left mounting portion 30L is disposed below the left ear.

  Since the wearing part 3 passes below the ear, the ear is not burdened when worn, and even if the sanitary mask 100 is used continuously for a long time, the ear is not painful. In addition, since the mounting portion 3 is arranged so as to go around the back of the neck, the attaching / detaching portion 31 is not easily displaced up and down. The back of the head has a large inclination in the front-rear direction, whereas the back of the neck has a small inclination in the front-rear direction. It becomes difficult for the mask body 10 to fall off.

  Furthermore, by arranging the connecting position 25 of the mounting portion 3 with respect to the support portion 2 ahead of the ear, the angle θ at the connecting position 25 of the support portion 2 is increased, and the mask main body portion 10 fits well to the wearer's face. Can be made. If the mask main body 10 can be satisfactorily fitted to the wearer's face, the gap between the mask main body 10 and the face can be reduced, and the mask main body 10 will not easily fall off.

  The support part 2 is arrange | positioned ahead of the wearer's ear. That is, the right support portion 20R is disposed in front of the right ear, and the left support portion 2 is disposed in front of the left ear. For example, it is arranged in front of the ear with respect to the lower end of the wearer's earlobe.

  The support portion 2 has flexibility, both ends are fixed to the mask main body portion 10, and the connection position 25 is pulled backward by the mounting portion 3. For this reason, the support part 2 becomes the broken line shape which connected the fixing positions 23 and 24 of both ends, and the connection position 25 with the straight line, and the connection position 25 located in the back is located ahead of the ear | edge.

  Compared with the ear hook part of a conventional sanitary mask, the support part 2 is similar in that it has a string shape and both ends thereof are fixed to the mask main body part 10. However, the mounting portion 3 is connected to the support portion 2, and even when the mounting portion 3 is pulled backward by the mounting portion 3, the entire portion is disposed in front of the ear of the wearer. Therefore, the support part 2 has only a length that is difficult to hang on the ear, and the length of the support part 2 is significantly different from that of a conventional sanitary mask. Can do.

  The support unit 2 applies a backward force to the mask main body unit 10. More specifically, a backward downward force is applied to the upper fixed position 23, and a backward upward force is applied to the lower fixed position 24. Therefore, if the connecting position 25 is moved forward, the force applied to the upper fixed position 23 becomes more downward, the force applied to the lower fixed position 24 becomes more upward, and the angle θ between these forces is formed. Becomes larger.

  A vertical tension according to the angle θ is applied to the mask main body 10 when the mask is mounted. For this reason, if the angle θ increases, the mask main body 10 changes to a more curved three-dimensional shape. Further, when the angle θ is increased, the upper edge of the mask body 10 is pressed against the nasal muscle part (nasal spine) above the nasal head, and the lower edge of the mask body is pressed behind the chin behind the chin. be able to. As a result, the mask main body 10 can be satisfactorily fitted to the face. For example, it becomes difficult to form a gap at the upper and lower edge portions of the mask. Moreover, it becomes difficult for the mask main-body part 10 to fall off.

  The connecting portion 3 is slidably connected to the support portion 2. For this reason, the connecting position 25 can be slightly moved in the vertical direction, and the direction of the force applied to the upper and lower portions of the mask main body 10 can be adjusted. For this reason, the direction of the force applied to the mask main body 10 can be finely adjusted according to the physical characteristics of the wearer, for example, the size and shape of the jaw and nose. Therefore, the mask main body 10 can be satisfactorily fitted to the faces of various wearers.

  In addition, the material of the support part 2 and the mounting part 3 can use the rubber string similar to the ear hook string used for the conventional sanitary mask. For this reason, the sanitary mask 100 can be provided at low cost. However, the sanitary mask 100 according to the present invention can use other materials as the material of the support portion 2 and the mounting portion 3.

  FIG. 5 is a view showing another example of the state when the sanitary mask 100 of FIG. 1 is worn, and a view seen from the left side of the wearer. In addition, since the state at the time of attachment is left-right symmetric, the figure seen from the right side is abbreviate | omitted.

  The sanitary mask 100 of FIG. 5 has a longer support 2 than the case of FIG. In this case, the angle θ formed by the support portion 2 is reduced, a gap is generated between the mask main body portion 10 and the face, and the mouth and nostril directly touch the outside air, so that the sanitary mask 100 does not function sufficiently. In addition, the mask main body 10 is easy to drop off. In FIG. 5, there is a gap between the lower edge of the mask body 10 and the face. However, if the connecting position 25 moves further downward, the gap between the upper edge of the mask body 10 and the face. And the mask becomes easy to drop off.

  The length of the support part 2 is shortened by pulling the operation element 22 of the adjustment part 21. For this reason, if the operator 22 is pulled with the sanitary mask 100 attached, the angle θ formed by the support portion 2 increases, and the state changes to the state of FIG. 4 in which the mask main body portion 10 fits well to the face. .

  In this manner, the sanitary mask 100 includes the adjustment unit 21 so that the length of the support unit 2 can be finely adjusted according to the physical characteristics of the wearer, for example, the size and shape of the jaw and nose. it can. Therefore, the mask main body 10 can be satisfactorily fitted to the faces of various wearers, the convenience of the sanitary mask 100 can be improved, and the manufacturing cost can be reduced.

  Furthermore, the adjustment of the length of the support portion 2 by the adjustment portion 21 can be performed not only immediately after mounting, but also when the mask body 10 does not fit well due to long-time mounting. For this reason, the sanitary mask 100 is suitable for long-time wearing.
