[Modes for carrying out the invention]

[0009] Hereinafter, preferred embodiments for carrying out the present invention will be described with reference to the drawings. Note that the following embodiments are not intended to limit the invention as defined in each claim, and not all combinations of features described in the embodiments are necessarily essential to the solution of the invention. Furthermore, in these embodiments, the scale and dimensions of each component may be exaggerated, and some components may be omitted.

[0010] [Overall components of the eye mask] As shown in Figures 1 and 2, the eye mask 1 comprises a main body portion 10 having a shape that covers at least the area around the wearer's eyes when worn, a functional body 20 provided on the main body portion 10, and a pair of ear loops 30 attached to both ends of the main body portion 10 in the left-right direction.

[0011] In this specification, "up and down direction," "left and right direction," and "front and back direction" refer to the up and down direction, left and right direction, and front and back direction when the wearer is wearing the eye mask 1. In this specification, "eye" refers to the general term for parts located inside the eye socket, such as the eyeball, eyelids, and eyelashes. Furthermore, in this specification, "periphery of the eye" refers to the general term for parts located near the outside of the eye socket, such as the lower edge of the forehead, eyebrows, the space between the eyebrows, the bridge of the nose, and the upper edge of the cheeks.

[0012] [Main Unit Configuration] As shown in Figures 1 and 2, the main body 10 is formed in a sheet shape and has a first main body 10A which constitutes one side in the left-right direction with respect to a third imaginary line VL3 which passes vertically through the left-right center of the main body 10, and a second main body 10B which constitutes the other side in the left-right direction with respect to the third imaginary line VL3. The first main body 10A and the second main body 10B are formed to be the same shape and size and are arranged to be symmetrical with respect to the third imaginary line VL3 as the axis of symmetry.

[0013] The main body portion 10 has a shape that covers the wearer's eyes and the area around the eyes when worn. Specifically, the main body portion 10 has an elongated upper edge portion 11 and a lower edge portion 12 in the left-right direction, and a pair of side edges 13 that extend from both ends of the upper edge portion 11 to both ends of the lower edge portion 12, and is formed as a long rectangle in the left-right direction overall. Note that "rectangular shape" includes both a shape in which the main body portion 10 is a perfect rectangle and a shape in which the main body portion 10 is approximately rectangular.

[0014] In this embodiment, the main body 10 has been described as having a shape that covers the wearer's eyes and the area around them when worn, but it is not limited to this, and may have a shape that covers only the area around the wearer's eyes when worn. That is, the main body 10 may have an opening in the area facing the wearer's eyes.

[0015] The upper edge 11 and the lower edge 12 are formed in an inclined shape that slopes upward and is located at the center of the main body 10 in the left-right direction. The side edge 13 is formed in an arc shape that curves outward in the left-right direction of the main body 10. Furthermore, the connection between the upper edge 11 and the side edge 13, and the connection between the lower edge 12 and the side edge 13, are each formed in an arc shape that curves outward from the main body 10.

[0016] The shape of the main body portion 10 is not limited to this, and for example, at least one of the upper edge portion 11 and the lower edge portion 12 may be formed in a straight line extending along the left-right direction, at least one of the upper edge portion 11 and the lower edge portion 12 may be formed in an inclined shape that is inclined downwards and is at the left-right center of the main body portion 10, at least one of the upper edge portion 11 and the lower edge portion 12 may be locally protruding or curved, the side edge portion 13 may be formed in a straight line extending along the up-down direction, the side edge portion 13 may be locally protruding or curved, at least one of the upper edge portion 11 and the side edge portion 13 and the lower edge portion 12 and the side edge portion 13 may be perpendicular, or it may have any other known shape.

[0017] The main body part 10 has an upper through-hole part 14 that extends from the upper edge part 11 to the lower edge part 12 at the central part of the main body part 10 in the left-right direction and penetrates the main body part 10 in the front-back direction, and a lower through-hole part 15 that extends from the lower edge part 12 to the upper edge part 11 at the central part of the main body part 10 in the left-right direction and penetrates the main body part 10 in the front-back direction.

[0018] The upper through-hole part 14 is an upper notch that extends from the upper edge part 11 to the lower edge part 12. Specifically, the upper through-hole part 14 is an upper notch defined by a pair of upper inner edge parts 16 that extend from the upper edge part 11 toward the third virtual line VL3. Since the upper through-hole part 14 is an upper notch, when the ear hook part 30 is worn on the wearer's ear, the upper inner edge parts 16 narrow inward in the left-right direction, so the lower through-hole part 15 can be easily widened. Note that the upper through-hole part 14 may be an upper cut that extends from the upper edge part 11 to the lower edge part 12.

[0019] From the viewpoint of widening the movable range of the upper inner edge part 16 and easily widening the lower through-hole part 15, the vertical length L1 of the upper through-hole part 14 is preferably 15% or more, more preferably 20% or more, and still more preferably 25% or more with respect to the vertical length L2 of the main body part 10. Also, from the viewpoint of maintaining the strength of the eye mask 1, the length L1 is preferably 40% or less, more preferably 35% or less, and still more preferably 30% or less with respect to the length L2.

[0020] In this specification, the "vertical length L1 of the upper through-hole part 14" is the length along the vertical direction from the upper end to the lower end of the upper inner edge part 16 as shown in FIG. 3. Also, the "vertical length L2 of the main body part 10" is the length along the vertical direction from the upper edge part 11 to the lower edge part 12 as shown in FIG. 4. Note that when the upper edge part 11 is not formed in a straight line extending along the left-right direction, the tangent line along the left-right direction of the upper edge part 11 is used as a reference. Similarly, when the lower edge part 12 is not formed in a straight line extending along the left-right direction, the tangent line along the left-right direction of the lower edge part 12 is used as a reference.

[0021] Furthermore, it is preferable that the vertical length L1 of the upper through-hole 14 be set taking into consideration not only the vertical length L2 of the main body 10 described above, but also the vertical length L3 of the lower through-hole 15.

[0022] For example, if the vertical length L1 of the upper through-hole 14 is 40% of the vertical length L2 of the main body 10, then from the viewpoint of ensuring the strength of the portion MP between the upper through-hole 14 and the lower through-hole 15 of the main body 10, it is preferable that the length L1 be 80% or more, more preferably 83% or more, and even more preferably 86% or more of the vertical length L3 of the lower through-hole 15. Furthermore, from the viewpoint of optimizing the range of motion (degree of opening) of the lower through-hole 15, the length L1 is preferably 100% or less, more preferably 96% or less, and even more preferably 92% or less of the length L3.

[0023] Furthermore, for example, if the vertical length L1 of the upper through-hole 14 is 15% of the vertical length L2 of the main body 10, then from the viewpoint of optimizing the opening angle of the lower through-hole 15 when the eye mask 1 is worn, the length L1 is preferably 30% or more, more preferably 33% or more, and even more preferably 36% or more of the vertical length L3 of the lower through-hole 15. Also, from the viewpoint of ensuring the range of motion (degree of opening) of the lower through-hole 15, the length L1 is preferably 46% or less, more preferably 43% or less, and even more preferably 40% or less of the length L3.

[0024] Furthermore, for example, if the vertical length L1 of the upper through-hole 14 is 25% or more and 30% or less of the vertical length L2 of the main body 10, then the length L1 is preferably 40% or more, more preferably 45% or more, and even more preferably 50% or more of the vertical length L3 of the lower through-hole 15, from the viewpoint of ensuring the strength of the portion MP between the upper through-hole 14 and the lower through-hole 15 of the main body 10 while ensuring the range of motion (degree of opening) of the lower through-hole 15. Also, the length L1 is preferably 65% ​​or less, more preferably 60% or less, and even more preferably 55% or less of the length L3.

[0025] In this specification, "the vertical length L3 of the lower penetration portion 15" refers to the length along the vertical direction from the upper end to the lower end of the lower inner edge portion 17, as shown in Figure 3.

[0026] The vertical length L1 of the upper through portion 14 is preferably 1.0 cm or more, more preferably 1.5 cm or more, and even more preferably 2.0 cm or more. Furthermore, the length L1 is preferably 3.5 cm or less, more preferably 3.0 cm or less, and even more preferably 2.5 cm or less.

[0027] The lower through-section 15 is a lower notch extending from the lower edge 12 toward the upper edge 11. Specifically, the lower through-section 15 is a lower notch defined by a pair of lower inner edge portions 17 extending from the lower edge 12 toward the third imaginary line VL3. The fact that the lower through-section 15 is a lower notch makes it easy to prevent the overlap between the wearer's nose and the main body portion 10 when wearing the eye mask 1. The lower through-section 15 may also be a lower cut extending from the lower edge 12 toward the upper edge 11.

[0028] The vertical length L3 of the lower through-hole 15 is preferably 36.5% or more, more preferably 41.5% or more, and even more preferably 46.3% or more, of the vertical length L2 of the main body 10, from the viewpoint of widening the range of motion of the lower inner edge 17 and increasing the opening angle of the lower through-hole 15 when the eye mask 1 is worn. Furthermore, from the viewpoint of maintaining the strength of the eye mask 1, the length L3 is preferably 61.0% or less, more preferably 57.4% or less, and even more preferably 52.5% or less, of the length L2.

[0029] The vertical length L3 of the lower through portion 15 is preferably 3.0 cm or more, more preferably 3.4 cm or more, and even more preferably 3.8 cm or more. Furthermore, the length L3 is preferably 5.0 cm or less, more preferably 4.7 cm or less, and even more preferably 4.3 cm or less.

[0030] The opening angle of the lower through-hole 15 (lower notch) is preferably 1° or more, more preferably 4° or more, and even more preferably 8° or more, from the viewpoint of increasing the opening angle of the lower through-hole 15 when the eye mask 1 is worn. Furthermore, the opening angle is preferably 36° or less, more preferably 26° or less, and even more preferably 16° or less, from the viewpoint of securing the non-jointed area A2 of the main body 10 and the ear hook 30 and securing the area of ​​the functional body 20.

[0031] In this specification, the "opening angle of the lower penetration portion 15" is the angle θ1 between the fourth virtual line VL4 extending along one lower inner edge portion 17 and the fifth virtual line VL5 extending along the other lower inner edge portion 17, as shown in Figure 3. Furthermore, the "fourth virtual line VL4 extending along the lower inner edge portion 17" and the "fifth virtual line VL5 extending along the lower inner edge portion 17" are virtual lines that extend along the straight portion of the lower inner edge portion 17 that converges toward the third virtual line VL3.

[0032] The main body 10, having the above configuration, is configured to hold the functional body 20. Specifically, the main body 10 is configured to hold the functional body 20 between an inner sheet 40 located on the skin side of the wearer when worn and an outer sheet 50 located on the non-skin side of the wearer when worn.

[0033] As a method for holding the functional body 20, known methods can be used, such as enclosing it in the internal space defined by the inner sheet 40 and the outer sheet 50, or adhering it to at least one of the inner sheet 40 and the outer sheet 50.

[0034] The peripheral edges of the inner sheet 40 and the outer sheet 50 are joined to each other when the functional body 20 is positioned between the inner sheet 40 and the outer sheet 50. Known joining methods such as adhesive bonding, sewing, fusion bonding, and crimping can be used to join the inner sheet 40 and the outer sheet 50.

[0035] In this embodiment, a configuration in which the peripheral edges of the inner sheet 40 and the outer sheet 50 are joined has been described, but the invention is not limited to this. For example, by locally leaving the inner sheet 40 and the outer sheet 50 unjoined, an opening and storage space that allows the functional body 20 to be inserted and removed may be formed between the inner sheet 40 and the outer sheet 50.

[0036] The inner sheet 40 is breathable. This has the advantage that, for example, if the functional body 20 has a function to release water vapor, it can efficiently release water vapor.

[0037] The outer sheet 50 is airtight or non-airtight. This allows the direction of water vapor release to be defined, and therefore, for example, if the functional body 20 has a function to release water vapor, it has the advantage of being able to release water vapor efficiently.

[0038] In this specification, an air permeability of less than 30,000 seconds / 100 mL is defined as "air permeable," an air permeability of 30,000 seconds / 100 mL or more but less than 80,000 seconds / 100 mL is defined as "poorly air permeable," and an air permeability of 80,000 seconds / 100 mL or more is defined as "non-air permeable." In this specification, "air permeability" is a value measured according to JIS P8117 (2009 revised edition), where 100 mL of air permeates 6.42 cm³ under constant pressure. 2 It is defined as the time it takes for air to pass through an area. Air permeability can be measured with a Wangyan type air permeability meter.

[0039] The inner sheet 40 may be poorly permeable or non-permeable, and the outer sheet 50 may be permeable. Furthermore, a portion of the inner sheet 40 or the outer sheet 50 may be permeable, poorly permeable, or non-permeable.

[0040] The materials for the inner sheet 40 and the outer sheet 50 can be materials that have been conventionally used in the field of eye mask technology. For example, nonwoven fabrics, woven fabrics and fibrous sheets such as paper, resin foam sheets, metal sheets, or combinations thereof can be used. Among these, nonwoven fabrics are preferred from the viewpoint of ease of processing and economic efficiency. The inner sheet 40 and the outer sheet 50 according to this embodiment are made of nonwoven fabric.

[0041] The nonwoven fabric fiber material is preferably composed of one or more fibers selected from, for example, polyester such as PET (polyethylene terephthalate); polyolefins such as PE (polyethylene), PP (polypropylene), and ethylene propylene copolymers; rayon; cotton; and wood pulp fibers such as lyocell. Furthermore, the nonwoven fabric can be manufactured using one or more of the above-mentioned materials by methods such as the air-through method, spunbond method, needle punch method, meltblown method, carding method, heat fusion method, water entanglement method, and solvent bonding method, and may be single-layer or multi-layer structure. The nonwoven fabric may also be chemically treated depending on the purpose.

[0042] Furthermore, the inner sheet 40 and the outer sheet 50 may each be a single-layer structure consisting of only one sheet material, whether single-layer or multi-layer, or a multi-layer structure made by layering two or more types of sheet materials. In addition, the inner sheet 40 and the outer sheet 50 may have different constituent materials. Specifically, the inner sheet 40, which is located on the skin side of the wearer when the eye mask 1 is worn, may be made of a material chosen for its pleasant feel against the skin.

[0043] In this embodiment, the main body 10 has been described as having an inner sheet 40 and an outer sheet 50, but it is not limited to this, and for example, it may have a configuration having only one of the inner sheet 40 and the outer sheet 50. That is, the main body 10 may be made of one sheet or multiple sheets. Also, the main body 10 may have other sheets between the inner sheet 40 and the functional body 20, or other sheets between the outer sheet 50 and the functional body 20. If the main body 10 is made of one sheet, the functional body 20 may be bonded to the one sheet, or it may be housed in a functional body housing formed on the one sheet.

[0044] [Functional structure] As the functional body 20, for example, a heating element capable of providing a warming sensation to the wearer or a cooling element capable of providing a cooling sensation to the wearer can be used. As the heating element, any known heating element can be used, such as a heating element that generates heat through the oxidation reaction of an oxidizable metal, or a heating element that generates hot steam through the oxidation reaction of an oxidizable metal, so a detailed explanation is omitted. As the cooling element, any known cooling element can be used, such as a cooling element in which water is retained in a water-retaining material such as a carbon component, fiber material, or water-absorbing powder, so a detailed explanation is omitted.

[0045] As shown in Figures 1 and 2, the functional body 20 is provided in the non-jointed area A2 of the main body 10 and the ear hook portion 30. Furthermore, the functional body 20 is provided on the main body 10 such that at least a portion of it is located between the lower penetration portion 15 and at least one of the ear hook portions 30. In this embodiment, the functional body 20 is provided on the first main body portion 10A and the second main body portion 10B respectively, so as to be symmetrical with respect to the third virtual line VL3.

[0046] The functional units 20 may be provided in two in the first main body 10A and two in the second main body 10B, or in one in the main body 10. Furthermore, when multiple functional units 20 are provided in the main body 10, the functions of each functional unit 20 may be the same or different, but it is preferable that they be the same.

[0047] The functional body 20 has a substantially square shape. However, the shape of the functional body 20 is not particularly limited and may have any shape, such as a square shape, a rectangular shape, a substantially rectangular shape, other polygonal shapes, and a circular shape. Furthermore, if the main body 10 has an opening in the area facing the wearer's eyes, the functional body 20 may have an opening at a position that coincides with the opening of the main body 10.

[0048] The separation distance D1 between the third virtual line VL3 and the functional body 20 is preferably 4.0 mm or more, more preferably 6.5 mm or more, and even more preferably 8.0 mm or more, from the viewpoint of securing the formation areas of the upper penetration portion 14 and the lower penetration portion 15 and the joining area of ​​the inner sheet 40 and the outer sheet 50. Furthermore, the above separation distance D1 is preferably 15.0 mm or less, more preferably 12.5 mm or less, and even more preferably 10.0 mm or less, from the viewpoint of improving the adhesion of the functional body 20 to the cheeks around the nose of the wearer when the eye mask 1 spreads outward in the left-right direction when worn.

[0049] In this specification, "the distance D1 between the third virtual line VL3 and the functional body 20" is the distance along the left-right direction from the third virtual line VL3 to the end of the functional body 20 on the third virtual line VL3 side, as shown in Figure 4. If the end of the functional body 20 on the third virtual line VL3 side is not formed in a straight line extending along the vertical direction, the tangent line along the vertical direction of the end of the functional body 20 on the third virtual line VL3 side shall be used as the reference.

[0050] The distance D2 between the side edge portion 13 and the functional body 20 is preferably 15 mm or more, more preferably 18 mm or more, and even more preferably 20 mm or more, from the viewpoint of securing the joining area A1 of the main body portion 10 and the ear hook portion 30. Furthermore, the above distance D2 is preferably 30 mm or less, more preferably 25 mm or less, and even more preferably 22 mm or less, from the viewpoint of securing the size of the functional body 20 and ensuring that the functional body 20 is in sufficient contact with the wearer's eye area.

[0051] In this specification, the "distance D2 between the side edge 13 and the functional body 20" is the distance along the left-right direction from the side edge 13 to the end of the functional body 20 on the side edge 13 side, as shown in Figure 4. If the side edge 13 is not formed in a straight line extending in the vertical direction, the reference is a line passing through the upper end of the end on the first virtual line VL1 side of the joining region A1 in the vertical direction. Similarly, if the end of the functional body 20 on the side edge 13 side is not formed in a straight line extending in the vertical direction, the reference is a tangent line along the vertical direction of the end of the functional body 20 on the side edge 13 side.

[0052] [Construction of the ear hook portion] As shown in Figures 1 and 2, the ear loop portion 30 is formed in a sheet shape and has an ear loop body 31 and an insertion portion 32 into which the wearer's ear can be inserted.

[0053] The ear hook body 31 has an upper side 31a, a lower side 31b, a first side 31c extending from one end of the upper side 31a to one end of the lower side 31b, and a second side 31d extending from the other end of the upper side 31a to the other end of the lower side 31b, and is formed in a substantially rectangular shape overall. The first side 31c has a shape that follows the side edge 13. The second side 31d is formed to be shorter than the first side 31c. In other words, the ear hook body 31 has a shape that tapers from the first side 31c to the second side 31d.

[0054] The insertion portion 32 is an arc-shaped notch extending from the vicinity of the first side edge 31c to the vicinity of the second side edge 31d. However, the shape of the insertion portion 32 is not limited to this; for example, it may be a straight notch or an opening.

[0055] The ear loop portion 30 may be made of the same material as the main body portion 10, or it may be made of a different material. For example, nonwoven fabric, woven fabric and paper fiber sheets, resin foam sheets, metal sheets, film sheets, elastic cords, or combinations thereof can be used.

[0056] The ear hook portion 30, having the above configuration, is attached to the main body portion 10 at an angle downward with respect to the left-right direction, and is configured to hold the main body portion 10 in front of the wearer's face so that at least the area around the wearer's eyes is covered by the main body portion 10.

[0057] The ear hook portion 30 is attached to the main body portion 10 by joining the vicinity of the first side edge 31c to the vicinity of the side edge portion 13 of the inner sheet 40 when the ear hook portion 30 is facing the inner sheet 40. As a method for joining the ear hook portion 30 to the main body portion 10, known joining methods such as adhesive bonding, fusion bonding, and crimping can be used.

[0058] The joining area A1 of the main body 10 and the ear hook portion 30 is located in the left-right center of the main body 10 and is inclined downward. Here, the inclination angle of the joining area A1 is preferably 10° or more, more preferably 20° or more, and even more preferably 25° or more, from the viewpoint of increasing the opening angle of the lower penetration portion 15 when the eye mask 1 is worn. Furthermore, the inclination angle is preferably 45° or less, more preferably 40° or less, and even more preferably 35° or less, from the viewpoint of securing the non-joining area A2 of the main body 10 and the ear hook portion 30 and securing the area of ​​the functional body 20.

[0059] In this specification, the "angle of inclination of joint region A1" is the angle θ2 between the sixth virtual line VL6, which extends along the end of joint region A1 on the third virtual line VL3 side, and the seventh virtual line VL7, which passes vertically through the lower end of the end of joint region A1 on the third virtual line VL3 side, as shown in Figure 4.

[0060] The angle θ3 formed by the first imaginary line VL1 passing horizontally through the upper end of the lower through portion 15 and the second imaginary line VL2 passing horizontally through the upper end of the lower through portion 15 and the left and right ends of the insertion portion 32 is preferably 10° or more, more preferably 15° or more, and even more preferably 20° or more, from the viewpoint of increasing the opening angle of the lower through portion 15 when the eye mask 1 is worn. Furthermore, the angle θ3 formed above is preferably 35° or less, more preferably 30° or less, and even more preferably 25° or less, from the viewpoint of preventing a gap from being formed between the eye mask 1 and the vicinity of the wearer's eyebrows when the eye mask 1 is worn.

[0061] In this specification, the "left-right tip of the insertion portion 32" refers to the intersection point P with the tangent line along the vertical direction of the insertion portion 32, as shown in Figure 4.

[0062] [Expected opening angle of the lower penetration when wearing an eye mask] As shown in Figure 5, with the above configuration, when the left and right ends of the insertion portion 32 are positioned on the first imaginary line VL1, the opening angle of the lower penetration portion 15 is 40° to 50°. This ensures that the opening angle of the lower penetration portion 15 is sufficient to prevent overlap between the wearer's nose and the main body portion 10, thereby preventing the formation of gaps near the boundary between the wearer's nose and eyes, and near the boundary between the wearer's nose and cheeks.

[0063] [How to use an eye mask] Next, the method of using the eye mask 1 according to this embodiment will be described. Before use, the eye mask 1 is stored sealed in packaging (not shown). However, it is not necessarily required that the entire eye mask 1 be sealed in packaging. For example, if the functional unit 20 is not integrated with the main body 10 (i.e., it can be attached later), it is sufficient that at least the functional unit 20 is stored sealed in packaging. That is, the main body 10 and the functional unit 20 may be packaged separately, or only the functional unit 20 may be packaged.

[0064] When using the eye mask 1, the wearer first removes the eye mask 1 from its packaging. Then, with the main body 10 placed over the wearer's eyes and the area around them, the wearer pulls each ear loop 30 with their fingers and inserts their ears into each insertion part 32. This allows the main body 10 to be held in front of the wearer's face so that it covers the wearer's eyes and the area around them, as shown in Figure 6, and provides the wearer with a warming or cooling sensation.

[0065] [Advantages of the eye mask according to this embodiment] The eye mask 1 according to this embodiment comprises a main body portion 10 having a shape that covers at least the area around the wearer's eyes when worn, a functional body 20 provided on the main body portion 10, and a pair of ear loops 30 attached to both left and right ends of the main body portion 10, wherein the main body portion 10 has a lower penetrating portion 15 in the left-right central part of the main body portion 10 that extends from the lower edge portion 12 to the upper edge portion 11 of the main body portion 10 and penetrates the main body portion 10 in the front-rear direction, and the functional body 20 is at least a part The main body portion 10 is provided such that it is located between the lower through portion 15 and at least one ear hook portion 30. The ear hook portion 30 has an insertion portion 32 into which the wearer's ear can be inserted. The ear hook portion 30 is mounted at an angle to the left and right of the main body portion 10. The angle θ3 between a first imaginary line VL1 passing through the upper end of the lower through portion 15 in the left and right direction and a second imaginary line VL2 passing through the upper end of the lower through portion 15 and the left and right ends of the insertion portion 32 is between 10° and 35°.

[0066] With the eye mask 1 having such a configuration, the angle θ3 is between 10° and 35°, so when the ear loop portion 30 is attached to the wearer's ear, the lower penetrating portion 15 spreads outward in the left and right directions starting from the upper end. As a result, as shown in Figure 7, gaps are less likely to form between the eye mask 1 and the area near the boundary between the wearer's nose and eyes, or the area near the boundary between the wearer's nose and cheeks (collectively referred to as "near-boundary area BA"), improving the fit of the functional body 20. This allows the warming or cooling sensation from the functional body 20 to be applied to the near-boundary area BA as well, thereby improving the warming or cooling sensation given to the wearer.

[0067] In the eye mask 1 according to this embodiment, the functional body 20 is provided in the non-jointed area A2 of the main body 10 and the ear loop portion 30. With this configuration, since the ear loop portion 30 is not interposed between the wearer and the functional body 20, the fit of the functional body 20 can be improved.

[0068] In the eye mask 1 according to this embodiment, the main body 10 has a first main body 10A which constitutes one side in the left-right direction with respect to a third virtual line VL3 which passes vertically through the left-right center of the main body 10, and a second main body 10B which constitutes the other side in the left-right direction with respect to the third virtual line VL3, and the functional body 20 is provided on the first main body 10A and the second main body 10B, respectively. With the eye mask 1 having such a configuration, the functional body 20 is not located in the left-right center of the main body 10. As a result, when the eye mask 1 is worn, the functional body 20 is not located on the wearer's nose, and the upper side of the functional body 20 can be easily narrowed inward in the left-right direction of the main body 10, so that the main body 10 can be closely fitted.

[0069] In the eye mask 1 according to this embodiment, the main body portion 10 has an upper through portion 14 that extends from the upper edge portion 11 to the lower edge portion 12 of the main body portion 10 at the center of the main body portion 10 in the left-right direction and penetrates the main body portion 10 in the front-rear direction. With the eye mask 1 having such a configuration, when the ear loop portion 30 is attached to the wearer's ears, the area near the upper through portion 14 of the main body portion 10 (upper inner edge portion 16) narrows inward in the left-right direction, so the lower through portion 15 can be easily widened. In addition, because the area near the upper through portion 14 of the main body portion 10 narrows inward in the left-right direction, the functional body 20 can also come into contact with the area between the wearer's eyebrows, so that the warming or cooling sensation from the functional body 20 can be applied to the area between the wearer's eyebrows.

[0070] [Differentiation] The eye mask according to the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the technical concept of the present invention.

[0071] In the embodiments described above, the main body 10 was described as having an upper through-hole 14, but it is not limited to this, and it does not have to have an upper through-hole 14.

[0072] It is clear from the claims that the above-mentioned modifications are included within the scope of the present invention.
