Description

  The present invention relates to a face mask that covers the entire face of a wearer.

  Various masks covering the face have been proposed for the purpose of beauty and the purpose of obtaining a relaxed feeling. For example, Patent Document 1 describes a cosmetic mask in which a mask body 1 and an ear hook 2 are connected to each other. A pair of ear hooks 2 are provided on the left and right sides of the mask body 1. A drug layer 3 is applied to one side of the mask body 1. Then, the mask body 1 is stuck under the chin so that the drug layer 3 comes into contact with the chin under the face, and the pair of left and right ear hooks 2 are respectively locked to the left and right ears. According to the description of the same document, when the left and right ear hooks 2 are pulled and stuck under the chin, an extension stress acts on the mask body 1, and the mask body 1 is placed under the chin under the state where the slack under the chin is lifted. It is supposed to be in close contact.

  In addition to this cosmetic mask, Patent Document 2 discloses that the superposed sheet material is formed into a concavo-convex line shape along the shape extending from the upper part of the forehead to the chin, in the side view of the human face part. A bonded three-dimensional face mask is described. This face mask is used by impregnating lotion. The face mask is provided with a pair of left and right belt-like wearing belts for fixing the face mask to the face on the outer peripheral portion around the ears of each sheet material. Mechanical fasteners are attached to the wear belts at their tips. By engaging the mechanical fastener, the two wearing belts are fixed on the back of the wearer.

  Unlike a normal mask that covers the mouth and nose, a face mask that covers the entire face has a large shape. Therefore, when the face mask is fixed to the entire face, particularly the entire face including the chin, the above-mentioned pair of ear hooks and a pair of belt-like wearing belts are used, so that stable fixing without wrinkles or twisting is possible. It may not be possible.

  Therefore, the present invention provides a face mask that can be more stably fixed to the face than in the prior art.

  The present invention relates to a mask main body having a face-facing portion large enough to cover the entire face, a mask main body extending downward from the lower end of the face-contacting portion and large enough to cover the chin, and the mask main body The face mask is provided with two ear hooks attached along the longitudinal direction Y of the mask main body at positions on the left and right side portions in the lateral direction X.

  According to the present invention, the mask body is composed of the face part and the jaw part, so that not only the entire face but also the submandibular region is covered widely, and two ears are provided on the left and right sides of the mask body. Since the hanging portion is attached, the force for bringing the face contact portion and the jaw portion into close contact with the skin is likely to act, and the mask body can be stably fixed to the face and the chin.

The present invention will be described below based on preferred embodiments with reference to the drawings. The face mask 10 of the embodiment shown in FIG. The mask body 20 is composed of a thin member having a horizontal direction X and a vertical direction Y. In plan view, the mask body 20 has a substantially rectangular shape having an upper edge 20a and a lower edge 20b extending in the horizontal direction X and side edges 20c and 20d extending in the vertical direction Y. The mask body 20 is symmetrical with respect to the longitudinal center line _Cy .

  The mask main body 20 has a face contact portion 30 and a jaw contact portion 40 extending downward from the lower end of the face contact portion 30. The face contact portion 30 has a substantially rectangular shape close to a square in plan view. On the other hand, the jaw part 40 has a substantially rectangular shape that is long in the lateral direction X in plan view. The width of the face contact portion 30 and the width of the jaw contact portion 40 are substantially the same at the portion extending from the lower end of the face contact portion 30 to the upper end of the jaw contact portion 40. In the present specification, the width means the length in the horizontal direction X.

  The face contact portion 30 is large enough to cover the entire face. In general, with respect to the vertical direction Y, the upper side (upper edge) has a size that covers at least the area above the eyebrows to the forehead, the lower side covers the area to the chin, and the horizontal direction X covers the area between the left and right cheeks. If you do, you can say that it covers the entire face. On the other hand, the jaw portion 40 is large enough to cover the chin. In general, it can be said that the longitudinal direction Y covers the entire region of the lower jaw as long as it has a size covering the region from the tip of the jaw to the larynx and the lateral direction between the left and right lower jaw angles in the mandible. When the length Y in the longitudinal direction Y of the face contact portion 30 is 1, the length in the vertical direction Y of the jaw portion 40 is about 1/10 to 1/3, particularly about 1/6 to 1/4. Is preferred.

The specific size of the mask body 20, the width in the transverse direction X are both side edges 20c, in contact outer 20d, (not shown) tangent parallel side edges to the longitudinal center line C _Y when minus The distance between both tangents is preferably 110 to 300 mm, and more preferably 150 to 250 mm. Further, the upper edge tangent (not shown) and the lower edge tangent (not shown) are in contact with the entire length of the mask body 20, that is, the convex shapes of the upper edge 20a and the lower edge 20b and parallel to the horizontal center line (not shown). ) Is preferably 160 to 300 mm, more preferably 180 to 250 mm.

The face seal 30, along the longitudinal center line C _y of the mask body 20, in a substantially central zone of the face-contact portion 30, straight cut 31 of a predetermined length is provided. As will be described later, the cut 31 is provided to expose the wearer's nasal bridge and nostril and reduce breathing difficulty when the face contact portion 30 is brought into contact with the wearer's face.

  A total of four ear hooks 50 a to 50 d are attached along the vertical direction Y at the positions of the left and right side portions in the horizontal direction X of the mask body 20. Specifically, the first ear hooking portion 50a and the second ear hooking portion 50b are attached along the vertical direction Y on the left side as viewed in FIG. Of the two ear hooks, the first ear hook 50a is located near the upper edge 20a of the mask body 20 and the second ear hook 50b is located near the lower edge 20b of the mask body 20. ing. Moreover, the 1st ear hook part 50c and the 2nd ear hook part 50d are attached along the vertical direction Y at the right part toward the paper surface in the figure. Among the two ear hooks, among them, the first ear hook 50c is located near the upper edge 20a of the mask body 20, and the second ear hook 50d is located near the lower edge 20b of the mask body 20. ing.

Relates longitudinal center line C _y, it is attached to a position symmetrical to the first left ear shell 50a and the first right ear shell 50c. Similarly, relates longitudinal centerline C _y, the left second ear shell 50b and the right second ear shell 50d is also installed in a position symmetrical. The two first ear hooks 50a and 50c have the same shape, and the two second ear hooks 50b and 50d have the same shape. The first ear hooks 50a and 50c and the second ear hooks 50b and 50d are different in shape. However, depending on the specific application of the face mask 10, there is no problem in making the first ear hook portion and the second ear hook portion have the same shape.

  Each of the ear hooks is composed of a horizontally long sheet material. This sheet material is provided with linear notches 51a to 51d having a predetermined length extending in the horizontal direction X at a position substantially in the center in the vertical direction Y. The cuts 51a to 51d are provided in order to form an opening in the sheet material to form a loop, and to be hooked on the wearer's ear. As the sheet material, it is preferable to use a fiber sheet made of a fiber material such as a nonwoven fabric from the viewpoints of touch and economy. This fiber sheet is particularly preferably stretchable.

  Of the two ends of the straight cuts 51a to 51d, cuts 52a to 52d connected to the ends are provided at the positions of the ends located outside the lateral direction X. The cuts 52a to 52d are linear and extend along the vertical direction Y. The cuts 52a to 52d are provided in order to further increase the opening formed by the linear cuts 51a to 51d described above so that the wearer's ear can be more easily passed through the loop. Since the notches 52a to 52d make the opening large so that the ear hooking portion can be easily passed through the wearer's ear, in addition to the linear shape shown in FIG. 1, an arc shape or an arrow in which the concave portion faces the face portion 30 side. It may be a shape, or may be a unidirectional arc or a straight line on the upper side or the lower side with respect to the notches 51a to 51d.

  Each ear hooking part 50a-50d is attached to the mask main body 20 by linear joining parts 53a-53d. In FIG. 1, the joint portions 53 a to 53 d are shown by hatched patterns. The joint part 53a and the joint part 5b positioned up and down along the vertical direction Y are connected to each other, and it appears that a single joint part is formed. The same applies to the joint 53c and the joint 53d. For the formation of the joint portions 53a to 53d, for example, means such as fusion by heating with or without pressure, adhesion using an adhesive, and sewing can be appropriately employed. In addition, it is not necessarily required that each joint part 53a-53d is linear, but if it is the shape extended in one direction, wavy shape, curve shape etc. may be sufficient, for example, the oblique line of FIG. It is sufficient that the portion has a length that can be regarded as a linear shape and extends in one direction.

  As shown in FIG. 1, the pair of left and right first ear hooks 50 a and 50 c positioned on the upper side in the vertical direction Y of the mask main body 20 are attached to the face contact portion 30. On the other hand, the pair of left and right second ear hooks 50b and 50d positioned below the vertical direction Y of the mask body 20 are attached so as to straddle the face contact part 30 and the jaw part 40. Here, as a mode in which the second ear hooking portions 50b and 50d are attached so as to straddle the face contact portion 30 and the jaw portion 40, the second ear hooking portions 50b and 50d are attached to the second ear hooking portions 50b and 50d. Of the hanging portions 50b and 50d, a mode in which a portion of the ear that contacts the lower side of the ear is joined to the jaw portion 40 and a portion of the upper side of the ear is joined mainly to the face-facing portion 30 is preferable. For example, as shown in FIG. 1, when each ear hook is made of a single sheet-like material, the second ear hooks 50b and 50d are attached to the second ear hooks 50b and 50d. It is preferable that a portion that hits the lower side of the ear (a portion near the lower edge of the notches 51b and 51d and the ear hooking portions 50b and 50d) and the mask body 20 are joined on the jaw portion 40 side. On the other hand, of the second ear hooking portions 50b and 50d, the portion near the upper edge of the notches 51b and 51d and the ear hooking portions 50b and 50d is preferably based on the length in the longitudinal direction Y of the joint portions 53b and 53d. If it is bonded on the face part 30 side with a length of 50% or more, more preferably 80% or more, it can be said that it is “mainly” bonded to the face part 30.

  When the second ear hooking portions 50b and 50d are separated from a portion that hits the lower side of the ear and a portion that hits the lower side before being attached to the ear, such as a wide string-like material or bias tape, It is preferable that the part located below the ear is joined to the jaw part 40 and the part located above is mainly joined to the face part 30.

  As described above, the face mask 10 according to the present embodiment has four ear hooks, so it is a so-called four-point pattern, and two points described in Patent Documents 1 and 2 described in the background art section. The mask body 20 can be stably fixed to the wearer's face and submandibular region as compared with a cosmetological mask or a face mask. In addition, since the four ear hooks 50a to 50d are attached to the positions described above in relation to the face contact portion 30 and the jaw contact portion 40, each ear hook portion is hooked on the wearer's ear. In addition, the face contact portion 30 has a convex shape that conforms to the unevenness of the face, and the jaw portion connected to the face contact portion 30 covers the jaw, so that the mask body 20 as a whole is easily deformed into a boat-shaped three-dimensional shape. In addition, a force that attracts the face contact portion 30 and the jaw contact portion 40 in the mask main body 20 to the wearer's face and chin is easily applied. As a result, the face contact portion 30 and the jaw contact portion 40 can be stably fixed to the face. Although the ear hooks 50a to 50d shown in FIG. 1 are a sheet-like material, the ear hooks 50a to 50d may be a wide tape shape from the viewpoint of forming a linear joint. For example, a material having expansion and contraction properties such as a bias tape or a plain weave string can be used as the ear hooks 50a to 50d. In FIG. 1, the first and second ear hooks made of sheet-like material are attached adjacent to each other, but the first ear hooks 50a and 50c are joined to the facepiece 30, and the first If the two-ear hooks 50b and 50d are joined across the face contact 30 and the jaw part 40, the two ear hooks 50b and 50d may be separated from each other.

As shown in FIG. 1, in the face mask 10, when the ear hooking portions 50 a to 50 d are viewed in a state of being spread in the lateral direction X of the mask main body 20, the linear shape provided in each ear hooking portion 50 a to 50 d. The extending direction of the cuts 51 a to 51 d is inclined with respect to the lateral direction X of the mask body 20. The direction of the inclination is such that, of the two ends of the linear cuts 51 a to 51 d, the virtual extension line on the end side located outside the lateral direction X is directed to the lateral center line (not shown) of the mask body 20. The direction is approaching. As a result, as shown in FIG. 2, of the four ear hooking portions 50a to 50d, the left first ear hooking portion 50a and the left first ear hooking portion 50a, which are two ear hooking portions positioned vertically along the vertical direction Y. The extending direction of the straight cuts 51 a and 51 b in the two-ear hooking portion 50 b is inclined in different directions with respect to the lateral direction X. Although not shown, the same applies to the right first ear hook 50c and the right second ear hook 50d. Since each of the linear cuts 51a to 51d in the ear hooks 50a to 50d is inclined, the ear hooks 50a to 50d are coupled with the mounting positions of the ear hooks 50a to 50d described above. When it is hung, the force that attracts the face contact part 30 and the jaw part 40 to the wearer's face and chin is more likely to act on each ear hook part. From the viewpoint of making this action more prominent, as shown in FIG. 2, the angle θ _a formed by the notch 51a of the first ear hooking portion 50a and the lateral direction X is a horizontal center line (not shown) of the mask body 20. ) In the direction toward 0), preferably 0 to 60 degrees. Here, the direction toward the lateral center line (not shown) of the mask body 20 is defined as a positive angle. In the embodiment shown in FIG. 1, the end portion side located outside the notches 51 are inclined in the direction of the lower end portion 20b, but the angle theta _a falls within the range described above, the mounting position of the ear shell In particular, from the relationship with the position of the lower end side joint portion of the first ear hook portion 50a, it is possible to attach the first ear hook portion 50a in the upward direction as in the embodiments shown in FIGS. . In that case, θ _a is a direction away from the horizontal center line (not shown) of the mask body 20, and is preferably −70 to 0 degrees, and more preferably −60 to 0 degrees. That is, θ _a is preferably −70 to 70 degrees, particularly preferably −60 to 60 degrees. For the same reason, as shown in the figure, the angle θ _b formed by the cut 51b of the second ear hooking portion 50b and the horizontal direction X is positive with the direction toward the horizontal center line (not shown) of the mask body 20 being positive. 5 to 70 degrees, particularly preferably 10 to 60 degrees. θ _a and θ _b may be the same or different. When θ _a and θ _b are different, there is no particular limitation on the magnitude relationship between the two, but from the viewpoint of stability when mounted, θ _b is preferably larger than θ _a .

  3A to 3D show a procedure for mounting the face mask 10 on the wearer's face. First, as shown in FIG. 3A, the face-facing portion 30 is brought into contact with the face while the face-facing portion 30 is supported by a hand. Further, the straight cut 31 formed in the face contact portion 30 is opened, and the nose is passed through the cut 31.

  Next, as shown in FIG. 3B, among the four ear hooks, a pair of first ear hooks 50a and 50c positioned on the upper side in the vertical direction Y are hung on each ear. In this state, the pair of second ear hooks 50b and 50d are not yet hooked on the ears.

  Next, as shown in FIG. 3C, the remaining two ear hooks, that is, a pair of second ear hooks 50b and 50d positioned on the lower side in the vertical direction Y are hung on each ear. As a result of this operation, a folding line (indicated by a dotted line in FIG. 3C) extending in the lateral direction X is generated at the boundary position between the face-facing portion 30 and the jaw portion 40, and a mask is formed along this folding curve. The main body 20 is bent. As a result, the portion near the lower end of the face contact portion 30 and the jaw portion 40 are in close contact with the wearer's skin. In this way, the mounting state shown in FIG. 3D is completed. In the wearing state shown in FIG. 3D, in each ear, the first ear hooks 50a and 50c are positioned on the lower side, and the second ear hooks 50c and 50d are positioned thereon. Since the first and second ear hooks are hung on the ear in such a positional relationship, the second ear hook 50b, which is an ear hook with a high lifting effect of the face contact portion 30 and the jaw portion 40, is provided. , 50d is effective. As a result, the adhesion of the face contact portion 30 and the jaw contact portion 40 to the face and the chin is further improved.

  In the present embodiment, the mask body 20 is made of a thin flexible material. Examples of such materials include woven fabrics, nonwoven fabrics, knitted fabrics, films, porous bodies, and combinations of any two or more thereof. In addition, for example, if a pack-like effect is expected after applying cosmetics on the face, a resin film such as polyethylene or urethane can be used. The face mask 10 having the mask main body 20 made of such various materials is used, for example, for the purpose of beauty, the purpose of health care, the purpose of medical treatment, the purpose of obtaining a feeling of relaxation. Moreover, it can also be used at the time of sleep as a substitute for an eye mask. Furthermore, as a use form of the face mask of the present invention, the face mask in which the face part and / or the jaw part is made of the above material is applied with a cosmetic such as a cosmetic liquid or a pack material, and massage is performed. Or the effect by cosmetics etc. can be heightened by affixing a pack sheet or attaching it from the top after using these together.

  Depending on the specific application of the face mask 10, the constituent material itself of the mask body 20 can be appropriately selected according to the application and purpose. For example, when the face mask 10 is used for cosmetic purposes, health care purposes, medical purposes, etc., the mask body 20 can be impregnated and retained with whitening liquid, cosmetic liquid such as moisturizing liquid, pharmaceuticals, etc. Can be used. In this case, it is advantageous to include at least the face contact portion 30 in the mask body 20 with a drug or cosmetic that can enhance the health condition of the wearer's skin. In addition, when the face mask 10 is used for the purpose of health care or to obtain a relaxed feeling, a heat generating material or a material capable of generating steam heat can be used as a constituent material of the mask body 20. Further, when the face mask 10 is used instead of an eye mask, a light shielding material can be used as a constituent material of the mask body 20. Furthermore, the above-mentioned constituent materials can be used by being detachably attached to the mask body 20.

  FIG. 4 is an exploded perspective view of the face mask 10 in which heat generation is imparted to the face contact portion 30 in the mask main body 20. The mask main body 20 in the face mask 10 includes a first sheet 22 that constitutes a skin-facing surface, a second sheet 23 that constitutes an outer surface, and a heat generating portion 24 disposed between both sheets 22 and 23. have. On the outer surface of the first sheet 22, the ear hooking portions 50a to 50d in a state before use are stacked.

  Four heating parts 24 are used. Each of the heat generating parts 24 has the same shape, and has a substantially square shape in plan view. These four heat generating portions 24 are sandwiched between the first sheet 22 and the second sheet 23. Both sheets 22 and 23 are joined at their peripheral edge portions. Further, in order to prevent movement of the heat generating part 24 between the both sheets 22 and 23, by joining both the sheets 22 and 23, an individually independent space that can be accommodated in each heat generating part 24 is formed, It is preferable to accommodate each heat generating part 24 in the space. Further, a part of the heat generating part 24 and a part of the first sheet 22 or the second sheet 23 may be joined. In FIG. 4, four rectangular heat generating portions 24 are arranged only in the portion corresponding to the face-contact portion, but the shape, number, and location of the heat generating portions 24 are specific uses of the face mask 10. It can be changed as appropriate according to the situation.

  As will be described later, since the heat generating portion 24 utilizes heat generated by oxidation of the oxidizable metal, it is preferable that at least one of the sheets 22 and 23 is a material having air permeability.

  The heat generating part 24 is arranged at a position corresponding to the face contact part 30 in the first sheet 22 and the second sheet 23 constituting the mask body 20 (see FIG. 1). As will be described later, since the heat generating portion 24 is configured to include an oxidizable metal, its rigidity is higher than that of a fiber sheet such as a nonwoven fabric. As a result, there is a difference in rigidity between the face contact portion 30 where the heat generating portion 24 which is such a highly rigid member is disposed and the jaw portion 40 where the heat generating portion 24 is not disposed. Due to the difference in rigidity, the mask body 20 has a bending tendency at the face contact portion 30, the jaw portion 40 and the boundary portion. Using this bending tendency, in the face mask 10 of the present embodiment, the face contact portion 30 and the jaw portion 40 are connected to each other in the mounting procedure described above with reference to FIGS. In the meantime, the first sheet 22 is folded inward so as to face each other, so that these portions are in close contact with the face and chin.

  In addition, the rigidity as used in this specification means the bending rigidity measured by the cantilever method prescribed | regulated to JISL1085, for example.

  The bending tendency is caused by the fact that the face part 30 and the jaw part 40 are different in rigidity, and the face part 30 and the jaw part 40 are made of the same material. Can also be generated. For example, by forming a bending guide line composed of a heat seal portion, a cut line, or the like at the boundary portion between the face contact portion 30 and the jaw portion 40, folding is performed at the boundary portion between the face portion 30 and the jaw portion 40. A tendency to curvature occurs. The bending guide line can be a continuous line or a discontinuous line such as a dotted line or a dot row. The folding line guide line is a line that guides the mask body 20 to bend along the lateral direction X so that the mask body 20 can easily come into contact successfully from the wearer's face to the chin.

  FIG. 5 shows details of the heat generating portion 24. Each heat generating portion 24 includes a heat generating body 24a, a sheet 24b, and a sheet 24c. The sheet 24b is positioned on the sheet 22 side of the mask body 20 described above, and the sheet 24c is positioned on the sheet 23 side of the mask body 20. The heating element 24a is sandwiched between the sheets 24b and 24c. The heating element 24a contains an oxidizable metal, and is a part that generates water vapor heated to a predetermined temperature using heat generated by an oxidation reaction caused by the contact of the oxidizable metal with oxygen. . The heating element 24a includes an oxidizable metal, a reaction accelerator, an electrolyte, and water. Such a heating element 24a is made of, for example, a heating sheet or a heating powder. Such materials are known in the art.

  The sheet 24b of the heat generating part 24 is made of a moisture permeable sheet. On the other hand, the sheet 24c of the heat generating part 24 is a moisture permeable sheet or a non-moisture permeable sheet. When the sheet 24c is a moisture permeable sheet, the breathability of the moisture permeable sheet is lower than the breathability of the moisture permeable sheet 24b. By appropriately adjusting the air permeability of the sheet 24b and the sheet 24c, water vapor (steam heat) heated to a predetermined temperature is generated from the sheet 24b side, which is applied to the face of the wearer of the face mask 10. Become so. The degree of such air permeability adjustment is known in the art.

  By wearing the face mask 10 of the present embodiment, steam temperature generated from the face contact portion 30 is applied to the face, the entire face is warmed comfortably, and fatigue that appears in facial expressions can be effectively taken. Specifically, the trigeminal nerve is comfortably stimulated by steam heat and a relaxed feeling is produced, and the blood circulation becomes good and the facial muscles relax. In addition, the skin feels moist and is lustrous and glossy. As a result, a tired expression becomes a rich expression. Such an effect is similar to the effect of warming the face with a steam towel. Further, since it has the jaw part 40 connected to the face part 30, an upward pulling force acts on the lower jaw of the wearer by the action of the jaw part 40, so that the sagging of the face is lifted and the expression is tightened. It becomes.

  If the skin facing surface of the face-contact portion 30 in the face mask 10 of this embodiment is impregnated or held with a cosmetic liquid, a pharmaceutical product, etc., these liquids are applied to the wearer's skin by the promoting action caused by the steam heat. The effect that it becomes easy to osmose | permeate is produced.

FIG. 6 shows another embodiment of the ear hooking portion in the face mask 10 of the present embodiment. In addition, although the ear hook part shown in the figure is only the left first ear hook part 50a and the left second ear hook part 50b, the remaining two right ear hook parts have the same configuration. In the embodiment described above, straight cuts 51a to 51d are formed in the sheet material constituting the ear hook portion to form an opening in the sheet material. However, in the present embodiment, the sheet material is cut out to open the opening portion. 54a and 54b are formed. The openings 54a and 54b extend in the lateral direction X at the position of the substantially central portion in the longitudinal direction Y of the sheet material. The extending direction of the openings 54 a and 54 b is inclined with respect to the lateral direction X of the mask body 20. The direction of the inclination is a direction in which the virtual extension line on the outer end side of the two end portions in the lateral direction X of the openings 54 a and 54 b approaches the lateral center line C _x of the face-contact portion 30. It is. The virtual extension line of the opening 54a can be formed by an extension line that connects the arcuate outer edge 55c and the tip of the inner edge 55d.

  In the openings 54a and 54b, the upper edge 55a and the lower edge 55b are linear, and the outer edge 55c and the inner edge 55d in the extending direction are arcuate. Since the shape behind the ear is round, if the outer edge 55c of the openings 54a and 54b is arcuate, the openings 54a and 54b can easily fit into the ear. Further, when the outer edge 55c and the inner edge 55d of the openings 54a and 54b are arcuate, the appearance of the openings 54a and 54b is impressively preferable.

  In the openings 54a and 54b, the distance between the upper edge 55a and the lower edge 55b along the extending direction gradually widens toward the outer end 55c in the extending direction. When the distance between the upper edge 55a and the lower edge 55b gradually increases toward the outer end 55c, the openings 54a and 54b are more easily hooked on the ear. Moreover, since the opening parts 54a and 54b follow the shape of the back of an ear | tip, a fitting property becomes favorable. On the other hand, it is preferable to reduce the distance between the upper edge 55a and the lower edge 55b at a portion close to the inner end 55d from the viewpoint of reducing the load applied to the sheet material.

  The distance between the upper edge 55a and the lower edge 55b in the openings 54a and 54b is preferably 3 cm or less, particularly preferably 0.1 to 1 cm at the inner end 55d in the direction in which the openings 54a and 54b extend. is there. Further, from the viewpoint of improving ease of passing the openings 54a and 54b to the ear, fitability, and less burden on the sheet material, the distance between the upper edge 55a and the lower edge 55b is set to be the opening 54a. , 54b is preferably 0.5 to 7 cm, particularly preferably 1 to 5 cm at the outer end 55c in the extending direction.

  As described above, regarding the ear hooks 54a and 54b shown in FIG. 4, the explanations regarding the ear hooks of the embodiment described above are applied as appropriate to points that are not particularly described.

With respect to these embodiments, the description regarding the embodiments described above is applied as appropriate to points that are not particularly described. 7 to 9, the same members as those in FIGS. 1 to 6 are denoted by the same reference numerals, and the description thereof is omitted.

  7A to 7D show another embodiment of the linear notch 21 in the face mask 10 of the embodiment shown in FIG. Providing the cuts 21 has the advantage that the position of the nose region of the face-contacting portion 30 can be easily determined during the mounting operation as shown in FIG. Therefore, if the wearer's nasal bridge and nostril can be exposed, the notch 21 does not have to be a simple straight line, and may have the notch shape shown in FIGS. The cut shown in FIG. 7A is an inverted T-shape (a shape obtained by turning the T-shape upside down), and the cut shown in FIG. 7B is a cross-shaped. The cut shown in FIG. 7C has a substantially triangular shape. Instead of these cut shapes, a substantially triangular opening 21 ′ shown in FIG. 7D may be provided. From the viewpoint of ease of use, for example, in FIG. 7A, the length 21a in the lateral direction X (horizontal direction) is preferably 10 cm or less, and more preferably 8 cm or less. From the viewpoint of ease of use, ease of exposing the nostril and nostril, and reduction of breathlessness, the length 21b in the longitudinal direction Y (vertical direction) is preferably 3 to 10 cm, and more preferably 5 to 8 cm.

In the embodiments shown in FIGS. 8 and 9, the face mask 10 of these embodiments is different from the previously described embodiment in the ear hooking portion. Specifically, in the embodiment shown in FIG. 8, the inclined state of the linear cuts 51 a to 51 d formed in the ear hooks 50 a to 50 d is different from the embodiment described above. In the present embodiment, of the two ends of the linear cuts 51 a to 51 d, the virtual extension line on the end side located outside the lateral direction X is away from the lateral center line C _x of the mask body 20. These linear cuts 51a to 51d are inclined toward the direction. As a result, of the four ear hooks 50a to 50d, straight lines in the left first ear hook 50a and the left second ear hook 50b, which are two ear hooks positioned vertically along the vertical direction Y. The extending direction of the cuts 51 a and 51 b is inclined in different directions with respect to the lateral direction X. The same applies to the right first ear hook 50c and the right second ear hook 50d.

In the embodiment shown in FIG. 9, the slopes of the linear cuts 51a to 51d formed in the ear hooks 50a to 50d are different from each other. In the present embodiment, one of the two ends of the linear cut 51 a to 51 d, a virtual extension line of the end portion positioned outside the lateral direction X, as away from the longitudinal center line C _y of the mask body 20 These linear cuts 51a to 51d are inclined toward the direction. In addition, among the four ear hooking portions 50a to 50d, the left first ear hooking portion 50a and the left second ear hooking portion 50b, which are two ear hooking portions positioned vertically along the vertical direction Y, are provided. The direction in which the linear cuts 51a and 51b extend is inclined in the same direction with respect to the lateral direction X. The same applies to the right first ear hook 50c and the right second ear hook 50d. In this case, the angle formed by the straight cut 51a with the horizontal direction X and the angle formed by the straight cut 51b with the horizontal direction X may be the same or different. When the two angles are different, the angle formed by the cut 51b and the horizontal direction X is larger than the angle formed by the cut 51a and the horizontal direction X. It is preferable from the point of becoming high.

  Also in each of the above embodiments, when the face mask 10 is worn, the mask body 20 is easily deformed into a boat-shaped three-dimensional shape, and the face contact portion 30 and the jaw portion 40 in the mask body 20 The force of attracting and sticking to the lower jaw becomes easier to work. As a result, the face contact portion 30 and the jaw contact portion 40 can be stably fixed to the face.

  In the embodiment shown in FIG. 9, a linear notch 32 having a predetermined length extending in the lateral direction X is provided in the vicinity of the boundary between the face contact portion 30 and the jaw portion 40 in the mask body 20. . The cut 32 is located at a substantially central portion in the lateral direction X. This notch 32 is provided to improve the wearability of the face mask 10 by being applied to the position of the jaw when the mask body 20 is brought into contact with the wearer's face. Although the cut 32 is not provided in the face mask 10 of the embodiment shown in FIGS. 1 and 8 described above, it may be provided as necessary in these embodiments.

  As mentioned above, although this invention was demonstrated based on the preferable embodiment, this invention is not restrict | limited to the said embodiment. For example, in each of the embodiments described above, the heating element 24 is disposed on the face contact portion 30 to cause a difference in rigidity between the face contact portion 30 and the jaw contact portion 40. Instead of disposing the heating element 24 on the other side, by disposing another member having high rigidity on the face contact portion 30, even if a difference in rigidity occurs between the face contact portion 30 and the jaw portion 40. Good. Further, depending on the specific application of the face mask 10, the rigidity of the face contact portion 30 and the rigidity of the jaw contact portion 4 may be the same. For example, when the heating element 24 is arranged on the face contact portion 30 and the jaw contact portion 40, these portions have rigidity derived from the heating element 24. Therefore, the boundary portion acts as a bending guide line, and the mask body 20 is easily bent between the face contact portion 30 and the jaw portion 40.

  In each of the embodiments described above, the ear hooking portion is made of a sheet material, but the ear hooking portion may be formed using a string-like body having elasticity instead. In this case, all of the ear hooks made of the sheet material may be replaced with the ear hooks made of the string-like body, or a part of the ear hook made of the sheet material is replaced with the ear hook made of the string-like body. May be.
