Description

  The present invention relates to a mask worn on a user's face.

  Conventionally, the following configuration is known as a mask to be worn on the user's face, in particular, a mask called a super stereoscopic mask (see Patent Document 1).

FIG. 8 is a plan view of a mask 100 according to a conventional example. FIG. 9 is a perspective view showing a three-dimensional state of the mask 100 of FIG.
The mask 100 includes a pair of flat sheets 110 joined to each other at one end edge 111, and a pair of flat and substantially semicircular arc-shaped ear hooks 120 extending from the other end edges 112 of the sheets 110. Prepare. One end edge 111 of the sheet 110 has a substantially arc shape that bulges on the opposite side to the other end edge 112 of the sheet 110.

FIG. 10 is a perspective view showing a state in which the mask 100 of FIG. 9 is mounted on the user's face. FIG. 11 is a plan view showing the upper surface of FIG.
When the mask 100 is mounted on the user's face, the ear hooks 120 are respectively hung on the user's ears, and the sheet 110 is locked to the user's nose and chin on one end edge 111 side; The other end edge 112 is locked to the user's cheekbone.

  Here, according to the mask 100, since the one end edge 111 of the sheet 110 is formed in a substantially circular arc shape, the sheet 110 is locked to the user's nose and chin and covers the user's lip at a predetermined distance. Thereby, since the sheet | seat 110 does not contact | abut to a user's mouth, a user can perform a breath, a conversation, etc. comfortably, and can suppress generation | occurrence | production of the situation where a lipstick, lip balm, etc. adhere to a mask. .

Moreover, since the sheet 110 and the ear hook 120 are configured in a flat plate shape, the sheet 110 and the ear hook 120 are not bulky in a state where they are not worn on the user's face, and therefore can be comfortably carried.
JP 7-275384 A

However, according to the mask 100, when worn on the user's face, the one end edge 111 is locked to the user's nose and the other end edge 112 is locked to the user's cheekbone. There are the following problems.
Since the user's nose and cheekbone are generally raised as compared with the portion interposed between the nose and the cheekbone, the sheet 110 locked to the nose and cheekbone has nose and cheekbone. Is separated from a portion interposed between them (separated portion 200 in FIG. 11). For this reason, the internal space formed by the sheet 110 and the user's face cannot be sufficiently sealed.

  In addition, high humidity exhaled air leaks between the above-described sheet 110 and the portion interposed between the nose and the cheekbone, so that there is a problem that, for example, the glasses worn by the user are easily fogged.

  Therefore, an object of the present invention is to provide a mask that can improve the sealing performance of an internal space formed by a sheet and a user's face.

  The present inventors have found that the face can be covered from the user's nose to the cheekbone by providing an extending portion that extends from the portion of the sheet that is locked to the user's nose. It came to complete.

  Specifically, the present invention provides the following.

(1) A pair of flat sheets joined to each other at one end edge, and a pair of flat and substantially semicircular arc-shaped ear hooks extending from the other side edges of these sheets,
One end edge of the sheet is a face-mounted mask that is substantially arc-shaped and extends opposite to the other end edge of the sheet,
The mask further comprising a pair of flat plate-like extending portions extending from one end of one end edge of the sheet to one end of the other end edge.

  According to the invention of (1), in a state where the mask is mounted on the user's face, each of the ear hooks is hung on the user's ear, and the sheet is engaged with the user's nose and chin on one edge side. And is locked to the user's cheekbone on the other edge side. In addition, since the one end edge of the sheet is formed in a substantially arc shape, when the seat is attached to the user's face, the seat is locked to the user's nose and chin and covers the user's lip at a predetermined distance.

  Here, since a pair of extending portions extending from one end of the one end edge of the sheet to one end of the other end edge are further provided, when one end of the one end edge is locked to the user's nose, these extension portions are extended. Each of the protrusions covers the face from the user's nose to the cheekbone. Thereby, since the extension part contacts the face from the nose to the cheekbone, the sealing performance of the internal space formed by the sheet and the user's face can be improved.

  In addition, since the seat, the ear hooking portion, and the extending portion are all formed in a flat plate shape, they are not bulky in a state where they are not worn on the user's face, so that they can be carried comfortably.

  In addition, since the extending portion contacts the face from the nose to the cheekbone, the conventional problem of leakage of exhaled breath from between the sheet and the portion interposed between the nose and the cheekbone can be solved. For this reason, generation | occurrence | production of the situation that the spectacles which a user wears, for example can be suppressed.

  (2) The mask according to (1), wherein the outer periphery of the extending portion includes at least one curve that is convex in the extending direction in which the extending portion extends.

When the extending part is configured in a shape having a pointed part or a corner part in the extending direction, when the mask is mounted on the face, the corner part makes point contact with the face surface and touches the user. May be uncomfortable.
Here, according to the invention of (2), since the outer periphery of the extending part includes at least one curve that is convex in the extending direction, when the mask is mounted on the face, Since the curved portion is in line contact with the face surface, discomfort to the user can be reduced.

  Moreover, as long as a point contact part (for example, a pointed part and a corner) is not formed in the extending direction, the outer periphery of the extending part may include a plurality of curves. By appropriately combining a plurality of curves, it is possible to configure extending portions having various shapes, for example, extending portions having a shape that is excellent in appearance aesthetics and interest.

  Here, the “extending direction” corresponds to the upper direction of the user's face in other words in the state of wearing the mask.

  (3) The outer periphery of the extending part further includes a convex curve in the anti-extending direction, which is the opposite direction of the extending direction, and a convex curve in the anti-extending direction and a convex in the extending direction. The mask according to (2), wherein the curved line is a smoothly connected shape.

  According to the invention of (3), since the outer periphery of the extending portion has a shape in which the convex curve in the anti-extending direction and the convex curve in the extending direction are smoothly connected, the mask is attached to the face. In this case, since the extended portion is in line contact with the face surface, discomfort given to the user can be reduced.

  In addition, since it can be configured to include a convex curve in the anti-extending direction, it is possible to configure extended portions of various shapes, for example, it is possible to make the extended portion of the shape further excellent in appearance aesthetics and interest it can.

  Here, “smoothly connected” means that the curvatures are connected so as to continuously change, and specifically, a pointed portion or a corner is not formed in the connected portion. Refers to being connected.

  If convex curves are connected in the anti-extending direction, a pointed portion is formed in the extending direction, which is not preferable.

  (4) The mask according to any one of (1) to (3), wherein the extending portion is joined to the sheet so as to extend from one end of one end edge of the sheet to one end of the other end edge. .

Since the part where the extension part abuts is generally a sensitive part near the edge of the eye, the extension part may be required to have different characteristics (for example, excellent flexibility) from the sheet.
Therefore, according to the invention of (4), since the extending portion is separated from the sheet, it is possible to produce an extending portion having a shape or composition that gives desired characteristics different from the sheet. However, the extending portion does not necessarily have to have a characteristic different from that of the sheet.

According to the present invention, since a pair of extending portions extending from one end of the one end edge of the sheet to one end of the other end edge are further provided, when one end of the one end edge is locked to the user's nose. Each of these extending portions covers the face from the user's nose to the cheekbone. Thereby, since the extension part contacts the face from the nose to the cheekbone, the sealing performance of the internal space formed by the sheet and the user's face can be improved.
In addition, since the seat, the ear hooking portion, and the extending portion are all formed in a flat plate shape, they are not bulky in a state where they are not worn on the user's face, so that they can be carried comfortably.
In addition, since the extending portion contacts the face from the nose to the cheekbone, the conventional problem of leakage of exhaled breath from between the sheet and the portion interposed between the nose and the cheekbone can be solved. For this reason, generation | occurrence | production of the situation that the spectacles which a user wears, for example can be suppressed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the description of each embodiment other than the first embodiment, the same reference numerals are given to those common to the first embodiment, and the description thereof is omitted or simplified.

<First Embodiment>
[overall structure]
FIG. 1 is a plan view of a mask 1 according to the first embodiment of the present invention. FIG. 2 is a perspective view showing a three-dimensional state of the mask 1 of FIG.

  The mask 1 includes a pair of flat plate-like sheets 10 joined to each other at one end edge 11 and a pair of flat and substantially semicircular arc-shaped hook portions 20 extending from the other end edge 12 of the sheet 10. Prepare. One end edge 11 of the sheet 10 has a substantially arc shape extending to the opposite side of the other end edge 12 of the sheet 10.

In this embodiment, each of the ear hooks 20 is joined to each of the sheets 10 at the other end edge 12 and extends from the other end edge 12. Since the joining portion 15 between the sheet 10 and the ear hooking portion 20 has high rigidity, the hanging of the ear hooking portion 20 from the sheet 10 is suppressed, and the entanglement between the ear hooking portions 20 can be suppressed.
Moreover, when joining the sheet | seat 10 and the ear hook part 20 by welding, it is preferable to melt the fiber of an outer surface. Thereby, since the outer surface of a junction part becomes smooth, when carrying a mask, it can suppress that the masks with which it overlapped were entangled, for example.

  However, the ear hooking portion 20 may be integrally configured as a part of the sheet 10 as long as it extends from the other end edge 12.

The mask 1 further includes a pair of flat extension portions 30 extending from a portion 13 (one end of one end edge 11) of the sheet 10 that is locked to the user's nose to one end of the other end edge 12. . The outer periphery of the extending portion 30 has a shape in which a convex curve 31 in the extending direction and a convex curve 32 in the anti-extending direction are smoothly connected.
In the present embodiment, the extending portion 30 is integrally configured as a part of the sheet 10.

[Sheet]
Although the sheet | seat 10 has thermoplasticity and is not specifically limited, It is comprised with the nonwoven fabric containing a thermoplastic synthetic fiber. Thereby, the ear hooking portion 20 is heat-sealed to the sheet 10 at the other end edge 12.

The sheet 10 is, for example, a polyethylene / polypropylene core-sheath fiber or a polyethylene / polyethylene terephthalate core-sheath fiber, and is produced by a through-air method, a point bond method, or the like, and has a basis weight of 50 g / m ² or more and 100 g / m ² or less. The bending resistance is measured by the bending resistance A method (45 degree cantilever method) described in 8.91.1 of JIS L1096: 1999 General Textile Testing Method.
The sheet 10 has a bending resistance measured by a cantilever method described later of 100 mm or more and 200 mm or less. Such a sheet | seat 10 is preferable at the point by which the three-dimensional shape in the state with which the face was mounted | worn is hold | maintained.

  Moreover, it is preferable that the sheet | seat 10 is comprised more lowly than the ear hook part 20 at the point by which the solid | 3D shape in the state with which it was mounted | worn on the face is held more. Here, it is preferable to have appropriate flexibility so as not to impair a good touch feeling.

  For example, the structure by which the recessed part where a fiber is relatively dense was intermittently provided in the outer surface of the sheet | seat is mentioned. According to this configuration, since the fibers in the recess are relatively dense, the stretchability of the sheet is reduced by providing the recess. On the other hand, since the site | part with which the softness | flexibility was hold | maintained between each recessed part provided intermittently, it has moderate softness | flexibility.

[Ear hook]
The ear hook 20 has thermoplasticity and is not particularly limited. For example, the ear hook 20 is made of a nonwoven fabric containing thermoplastic synthetic fibers. Thereby, the ear hooking portion 20 is heat-sealed to the sheet 10 at the other end edge 12.

Moreover, it is preferable that the ear hook part 20 is comprised so that elastic expansion and contraction is possible at the point which can suppress the situation which gives a pain to a user's ear.
As such an ear-hanging portion, for example, an extension layer (for example, a nonwoven fabric in which propylene continuous fibers are welded together) and an elastic stretchable fiber that can be elastically stretched are formed. The structure by which the elastic layer (For example, the nonwoven fabric using the elastic yarn which consists of an elastomer, urethane, etc. of a thermoplastic synthetic fiber) was laminated | stacked is mentioned.

(Extension part)
In the present embodiment, the extending portion 30 is configured integrally with the sheet 10 and thus has the same configuration as the sheet 10.

If the area of the extension part 30 is too small, the extension part 30 may not come into contact with the face from the user's nose to the cheekbones. On the other hand, if the area is too large, for example, the extension part 30 may be in the user's eyes. Is preferably 5 cm ² or more and 20 cm ² or less. More preferably, it is 7 cm ² or more and 15 cm ² or less.
