Patent Document 1 describes devising the structure of the mask in order to facilitate handling during continuous production of sheet masks. It is described that a pair of ear hook members are accommodated within the outer shape and that both ear hook members are connected to each other by a connecting portion. The connection between the ear hook members can be easily released by, for example, pulling the ear hook members with fingers. In this way, when the pair of ear hook members are connected to each other at the connecting portion and integrated, the handling of the ear hook members during manufacturing is said to be facilitated.
Such a sheet-like mask in which ear hook members are connected to each other in a cuttable manner is also described in Patent Document 2, for example. The mask described in Patent Literature 2 is intended to cover the wearer's entire face, and does not cover a portion of the wearer's face.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described based on its preferred embodiments with reference to the drawings. In addition, in the following description of the drawings, the same or similar reference numerals are given to the same or similar parts. The drawings are basically schematic, and the ratio of each dimension may differ from the actual one.

The sheet-like mask of the present invention is typically for covering a part of the wearer's face, and is different from covering the entire face.
The mask 1 of the present invention has a longitudinal direction X corresponding to the vertical direction of the wearer and a lateral direction Y orthogonal thereto, and typically covers at least part of the wearer's face; A pair of ear hook members 3, 3 are connected to both ends of the mask body 2 in the horizontal direction Y and engaged with the left and right ears of the wearer. An example of this is shown in FIGS. The mask 1 shown in FIGS. 1 to 4 is a sheet-like mask in which the mask body 2 covers the nose and mouth of the wearer when worn.

The mask body 2 has a skin-facing surface 2a that faces the wearer's skin when worn and a non-skin-facing surface 2b that is located on the opposite side. A first panel 21 and a second panel 22 are arranged on both left and right sides of a fold line 20L extending in the longitudinal direction X through the . The “center portion of the mask body 2 in the horizontal direction Y” referred to here is typically the center of the mask body 2 in the horizontal direction Y. As shown in FIG. That is, the fold line 20L typically extends in the longitudinal direction X by bisecting the mask body 2 in the lateral direction Y. As shown in FIG. However, according to the present invention, the fold line 20L is not limited to passing through the exact center of the mask body 2 in the lateral direction Y, and the fold line 20L is not restricted to the exact center as long as the first panel 21 and the second panel 22 are folded over. It doesn't matter if it's off. In this embodiment, the mask 1 is typically formed symmetrically with respect to the folding line 20L.
In the illustrated embodiment, the fold line 20L extends vertically along the nose bridge of the wearer when worn.

Mask 1 can be in a folded configuration. When the mask 1 is folded, the mask main body 2 is folded along the folding line 20L with the skin-facing surface 2a facing inward so that the first panel 21 and the second panel 22 are overlapped, and the space between the panels 21 and 22 is folded. It is preferable to have a structure in which a pair of ear hook members 3, 3 are interposed between the two.
An example of this is shown in FIG. In this embodiment, in the folded mask 1, the mask body 2 is folded in half along the folding line 20L.

It is preferable that the mask body 2 is formed with a panel joint portion 23 in which edge portions extending in the vertical direction X from the folding line 20L of the first panel 21 and the second panel 22 are joined to each other. With both panels 21 and 22 unfolded as shown in FIGS. 1 and 3, the central portion of the mask body 2 in the horizontal direction Y including the panel joint 23 protrudes toward the non-skin facing surface 2b. A portion 25 is formed.
At the panel joint portion 23, both panels 21 and 22 are preferably joined to each other by known joining means such as fusion bonding and adhesive. Typically, the panel joint portion 23 is a fusion portion where the forming members of both panels 21 and 22 are joined together by fusion.

The panel joint 23 includes a nose-side joint 231 located on the upper side of the mask body 2 corresponding to the wearer's nose, and a chin-side joint corresponding to the wearer's chin and located on the lower side of the mask body 2. Preferably, the section 232 is included. Typically, the nose joint 231 and the chin joint 232 are spaced apart in the longitudinal direction X. Accordingly, the first panel 21 and the second panel 22 are not joined to each other between the nose-side joint portion 231 and the chin-side joint portion 232 . The three-dimensional shape part 25 is formed by forming the panel joint part 23 in this way. An example of this is shown in FIGS.

The panel joints 23 (nose-side joints 231 and chin-side joints 232) are arranged inside the outlines of the first panel 21 and the second panel 22, and are spaced between the panel joints 23 and the outlines. is preferably present. In other words, the first panel 21 and the second panel 22 are not joined so as to include their contour lines extending in the longitudinal direction X from the fold line 20L, and the contour lines of both panels 21 and 22 and their vicinity ( The forming members of the edge) are not joined together.
Since the panel joints 23 are arranged inside the contour lines of the first panel 21 and the second panel 22, stress is not applied to the panel joints 23 when, for example, the mask 1 is unfolded in the folded form. Even if it acts, it is possible to prevent the breakage of the mask body 2 starting from the panel joint portion 23 .
Furthermore, it is more preferable that the panel joint portion 23 is along the contour lines of the panels 21 and 22 . As a result, the shapes of the plurality of forming members of the portions (edges) of both panels 21 and 22 located outside the panel joint portion 23 are stabilized, and the mask 1 can be manufactured stably.
Due to the arrangement of the panel joints 23 described above, the panel joints 23 made up of fused parts and the like are prevented from being positioned on the outer edge (contour line) of the product, and the strength of the product is ensured. From the viewpoint of facilitating the maintenance of the shape and facilitating the lifting effect of the ear hook member connecting member 36 when the mask body 2 is unfolded, which will be described later, the interval G is preferably 0.1 mm or more, more preferably 0. 0.3 mm or more, more preferably 0.5 mm or more.
In addition, in the process of forming the panel joint portion 23 (the panel joint process described later) during the manufacture of the mask 1, the ear hook member 3 (ear hook member connection body 36) arranged between the two overlapping panels 21 and 22 From the viewpoint of preventing the inconvenience of being joined together with the panels 21 and 22, the gap G is preferably 10 mm or less, more preferably 5 mm or less, and even more preferably 3 mm or less.

Typically, the ear hook member 3 has a shape elongated in one direction, and is joined to the mask body 2 at an ear hook member joining portion 24 at one longitudinal end thereof.
It is preferable that the ear hooking member 3 is formed by cutting the ear hooking member 3 and provided with a planar line-of-sight cut portion 31 into which the wearer's ear is inserted when worn. The cuts 31 function as ear hooks into which the wearer's ears are inserted when the mask 1 is worn. can.
The notch 31 has a portion extending in one direction (horizontal direction Y) from the mask main body 2 side (ear hook member joint portion 24 side) toward the distal end side of the ear hook member 3, which is the opposite side, in plan view. is preferred.
Moreover, in addition to or instead of this, the cut portion 31 preferably has a portion extending in the vertical direction X in a plan view. That is, it is preferable that the cut portion 31 has a portion extending in a direction intersecting with the portion extending in one direction.
It is preferable that the portion of the notch 31 extending in the longitudinal direction X has a convex portion that protrudes toward the tip side of the ear hook member 3 . The notch 31 in the illustrated example has both this and the portion extending in the one direction, and as a whole forms the shape of the letter "J" in plan view.
In the present invention, the shape of the notch 31 in plan view is not particularly limited, and can be arbitrarily provided that it functions as an ear hook. A shape that does not have a

In the present invention, the mask body 2 optionally encloses the heating element 4 . The mask body 2 is typically arranged on the side closer to the wearer's skin than the heating element 4 and the heating element 4, and forms the inner surface of the mask 1 (the surface facing the wearer's skin). and an air-permeable back sheet 6 arranged on the side farther from the wearer's skin than the heating element 4 and forming the outer surface of the mask 1. - 特許庁A heating element 4 is interposed between the sheets 5 and 6 . Both sheets 5 and 6 have a larger area than the heating element 4 and extend outward from the periphery of the heating element 4 respectively. An example of this is shown in FIG.
The heat-generating element 4 includes a heat-generating composition 43, a non-breathable sheet 41 arranged on the side farther from the wearer's skin than the heat-generating composition 43 (the back sheet 6 side), and and a breathable sheet 42 arranged on the side closer to the skin (the side of the topsheet 5). A heat-generating composition 43 is interposed between the sheets 41 and 42 . The exothermic composition 43 contains an oxidizable metal powder, an electrolyte, water, etc., and generates heat by utilizing an oxidation reaction of the oxidizable metal powder upon contact with air. The water vapor generated inside the heating element 4 by the exothermic reaction of the exothermic composition 43 passes through the air-permeable sheet 42 and the top sheet 5 to the outside of the mask body 2, as indicated by a plurality of upward arrows in FIG. released.

The mask main body 2 may contain a volatile functional material such as a perfume in part or all of the constituent members such as the heating element 4. In this case, the volatile component of the functional material may 1 can migrate to the wearer's skin side.

As the material for each part of the mask 1, any material that can be used for this type of sheet-like mask can be used without particular limitation. The sheet material constituting the mask 1, specifically, for example, the material of the ear hook member 3, the sheets 41 and 42 constituting the heating element 4, the top sheet 5 and the back sheet 6, is mainly made of fibers such as nonwoven fabric. A fiber sheet, a resin film, and the like can be mentioned, and a laminate of two or more sheet materials can also be used.

The mask 1 is typically stored in a folded form, and is in the folded form as shown in FIG. 2 when not in use, such as during the distribution process of the mask 1 as a product. When using the folded mask 1, as shown in FIG. The pair of ear hanging members 3, 3 that are in place are folded outward. As shown in FIG. 1, the mask 1 in the worn state has a three-dimensional portion 25 with both panels 21 and 22 unfolded. As described above, the mask 1 is folded into a flat shape when not in use, so that it is relatively compact, easy to carry, and does not take up much space when stored. Since it has a shape and an appropriate space is formed between the mask main body 2 and the wearer's mouth, the feeling of suffocation and discomfort caused by wearing the mask is reduced, and the wearing feeling and adhesion are excellent.

As described above, when the first panel 21 and the second panel 22 are unfolded, the mask body 2 has a three-dimensional shape portion 25 protruding toward the non-skin facing surface 2b at the central portion in the lateral direction Y of the mask body 2. formed. It is preferable that the mask 1, which has a three-dimensional shape when worn, has an ear hook member connector 36 in which the pair of ear hook members 3, 3 are connected to each other via a connector 35. As shown in FIG.
That is, when the mask 1 is not in use, it is preferable that the pair of ear hook members 3, 3 have a connecting portion 35 where the ends of the pair of ear hook members 3, 3 on the side opposite to the joint side with the mask body 2 are joined together. When using the mask 1, the connecting portion 35 is cut to separate one of the pair of ear hook members 3, 3 from the other. An example of this is shown in FIGS.

The connection part 35 is typically positioned at the boundary between one and the other of the pair of ear hook members 3 , 3 in the ear hook member connector 36 . It is preferable that the connecting portion 35 can be easily cut by a simple operation such as lightly pulling the ear hook member connecting body 36 with fingers without using a cutting tool such as scissors.
The connecting portion 35 is typically a non-broken portion of a breaking guide line provided at a boundary extending in the longitudinal direction X between one and the other of the pair of ear hook members 3, 3 in the ear hook member connecting body 36. . It is preferable that two or more connecting portions 35 are intermittently arranged in the longitudinal direction X at intervals D1.

With the mask 1 having such a characteristic structure, the first panel 21 and the second panel 22 are unfolded as shown in FIG. 3 when the folded mask 1 shown in FIG. 2 is put on. In this process, the ear hook member connecting body 36, which connects the pair of ear hook members 3, 3 via the connecting portion 35, moves so as to be lifted from the skin facing surface 2a of the mask body 2. As shown in FIG. A gap into which a finger can be inserted is formed between the connecting portion 35 of the ear hook member connecting body 36 and the portion along the folding line 20L of the mask main body 2 such as the three-dimensional shape portion 25 . The ear hook member connector 36 can be gripped by inserting fingers into the gap, and the operation of wearing the mask 1 thereafter can be performed smoothly.
A mask that is substantially flat and does not have a three-dimensional shape as described in Patent Document 1, even if it is equipped with an ear hook member connecting body, does not allow the ear hook member to be connected when the folded mask is unfolded as described above. It is difficult for the body to float up. In addition, even if the ear hook member connecting body rises when the mask is unfolded, it is difficult to form a sufficient gap between the raised ear hook member connecting body and the mask main body to allow the fingers to be inserted. It is inferior to the mask 1 in terms of the operability of the ear hook member.
In addition, when manufacturing the mask 1 of the present invention, the ear hook member connecting body 36 in which the pair of ear hook members 3, 3 are integrated is handled. Stability is improved, and inconveniences such as unintentional turning-up or shifting of the ear hook member 3 during transportation are effectively prevented, so that the mask 1 can be stably manufactured with a high non-defective product rate.
Thus, the sheet mask of the present invention, represented by mask 1, is excellent both during manufacture and during use.

Particularly in this embodiment, as described above, the panel joint portion 23 that enables the formation of the three-dimensional shape portion 25 is configured to include the nose-side joint portion 231 and the chin-side joint portion 232 that are spaced apart in the longitudinal direction X. there is Therefore, when the mask main body 2 is unfolded, the ear hook member connecting body 36 is easily lifted, and the predetermined effects of the present invention can be achieved more reliably.

The length L1 in the horizontal direction Y in the unfolded state of the ear hook member connecting body 36 (see FIGS. 5 and 7A) corresponds to the length of a pair of the connecting portions 35 constituting the ear hook member connecting body 36 cut off. It is longer than the total L2 of the length L2a and L2b (see FIG. 7B) in the horizontal direction Y at the same position in the vertical direction X as the measurement position of the length L1 of each of the ear hook members 3 and 3. preferable. In short, the above-mentioned "total length L2" is the same position in the longitudinal direction X as the measurement position of the length L1 for each of the pair of ear hook members 3, 3 after the connecting portion 35 is cut (for example, in FIG. The total lengths L2a and L2b in the horizontal direction Y are measured at the position overlapping the double-headed arrow indicated by symbol "L1" in plan view), and the measured values are totaled, and L2=L2a+L2b.
Since the size relationship "length L1>total length L2" is established, the ear hook member connecting body 36 is easily lifted when the mask body 2 is unfolded, so that the predetermined effect of the present invention is more assured. can be played in The size relationship can be established, for example, when the pair of ear hook members 3, 3 forming the ear hook member connecting body 36 have elasticity in the horizontal direction Y. As shown in FIG.
From the viewpoint of making the mask 1 comfortable to wear on the ears due to the establishment of the size relationship, the ratio of the length L1 to the total length L2 is preferably 0.7 or more as L1/L2, More preferably, it is 0.8 or more.
In addition, from the viewpoint of making it easier for the ear hook member connecting member 36 to rise when the mask body 2 is unfolded, L1/L2 is preferably 0.99 or less, more preferably 0.95 or less.

From the viewpoint of making it easier for the ear hook member connecting body 36 to rise when the mask main body 2 is unfolded and thereby more reliably achieving the predetermined effects of the present invention, the ear hook member 3 is arranged in the horizontal direction Y. It is preferable to have stretchability.
The ear hook member 3 having stretchability in the lateral direction Y may be made of a stretchable sheet material, and stretchability as a whole is achieved by joining a stretchable material such as an elastic member to a non-stretchable sheet material. It may be something that can be expressed.

As the sheet material forming the ear hook member 3 having stretchability in the lateral direction Y, for example, (1) a stretchable nonwoven fabric in which stretchable fiber layers are integrated on both or one side of an elastic fiber layer, (2) ) A stretchable nonwoven fabric in which extensible fiber layers are integrated on both or one side of a net-like elastic sheet; (3) An extensible fiber layer is integrated on both or one side of an elastic sheet made of an elastic film; (4) a stretchable nonwoven fabric in which a large number of elastic filaments arranged so as to extend in one direction without intersecting each other are integrated into a stretchable fiber layer; A composite stretchable member can be exemplified in which an elastic member extending in one direction is fixed between two sheet materials made of nonwoven fabric or the like in a non-stretched state or stretched state. The "stretchable fiber layer" as used herein includes i) a fiber layer that is stretchable before being integrated with the material having elasticity, and ii) a fiber layer that is stretchable by machining or the like after being integrated with the material having elasticity. and a fibrous layer. Methods for integrating the elastic fiber layer and the stretchable fiber layer include, for example, a method of laminating them and entangling the fibers by hydroentangling or air-through, and a method of bonding by heat embossing, an adhesive, ultrasonic waves, or the like. is mentioned. As the composite elastic member (5), for example, those described in International Publication No. 2018/189781 can be used.

Examples of the sheet material forming the ear hook member 3 include a fiber sheet and a resin film, which can be appropriately selected according to the required quality of the mask 1 and the like.
Examples of the fiber sheet include nonwoven fabric, woven fabric, and knitted fabric.
Examples of the resin film include elastomer films.
Examples of the nonwoven fabrics include air through nonwoven fabrics, heat roll nonwoven fabrics, spunlace nonwoven fabrics, spunbond nonwoven fabrics, and meltblown nonwoven fabrics.
The sheet material forming the ear hook member 3 may have a single layer structure or a laminated structure of two or more layers. The laminated structure may be a laminated structure of sheet materials of the same type or a laminated structure of sheet materials of different types. An example of the latter laminated structure is a laminated structure of a nonwoven fabric and a resin film.

The ear hook member 3 contains an elastomer film from the viewpoint of making it easier for the ear hook member connector 36 to float when the mask body 2 is unfolded, thereby more reliably achieving the predetermined effects of the present invention. is preferred.
As the elastomer film, a film made from thermoplastic elastomer or elastic resin can be used.
Examples of the thermoplastic elastomer include thermoplastic elastomers such as polyethylene-based elastomers, styrene-based elastomers, polyolefin-based elastomers, polyester-based elastomers, and polyurethane-based elastomers.
Rubber etc. are mentioned as said elastic resin.
The elastomer film may contain one of these alone, or may contain two or more.
A preferred example of a sheet material forming the ear hook member 3 having stretchability in the lateral direction Y is a composite sheet having a three-layer structure in which an elastomer film is interposed between two layers of nonwoven fabric facing each other.

As described above, it is preferable that the ear hook member 3 is formed by cutting the ear hook member 3, and is provided with the planar line-of-sight cut portion 31 into which the wearer's ear is inserted when worn. The notch 31 preferably has a non-cut portion 32 of the ear hook member 3 at an intermediate position in the extending direction of the notch 31 in an unused state. That is, it is preferable that the cut portion 31 of the present embodiment is not continuous over the entire length in the extending direction and is discontinuous at the position where the non-cut portion 32 is formed. Since the notch 31 is discontinuous in this way, the ear hook member connecting body 36 is given stretchability in the lateral direction Y, so that the ear hook member connecting body when the mask body 2 is unfolded as described above. Lifting of 36 may be more likely. In addition, when the notch 31 is discontinuous, misalignment of the ear hook member connector 36 during transportation is effectively prevented during the manufacture of the mask 1, so that the non-defective product rate of the mask 1 can be further improved. . Discontinuing the cut 31 in this way is useful both during manufacturing and during use of the mask 1 .
Since the ear hook member 3 preferably has elasticity in the horizontal direction Y, the cut portion 31 has a portion extending in the vertical direction X and a non-cut portion in the portion extending in the vertical direction X. , is particularly preferred.

From the viewpoint of ensuring the effect of the ear hook member connector 36, it is preferable to set the dimensions of each part of the ear hook member connector 36 (see FIG. 6) as follows. Note that the dimensions of each part below are those in the unfolded and extended state of the ear hook member connector 36 . The term "unfolded and stretched state" as used herein means that the ear hook member connecting body 36 is spread flat to be in a developed state, and the ear hook member connecting body 36 in the spread state is stretched to the maximum so that it becomes the same as the design dimension. It means the state expanded to.
The length 35L of the connecting portion 35 in the longitudinal direction X is preferably 0.1 mm or more, more preferably 0.3 mm or more, still more preferably 0.5 mm or more, and preferably 20 mm or less, more preferably 10 mm or less, and further preferably 0.5 mm or more. It is preferably 5 mm or less.
