Description

Technical Field

[0001] The present invention relates to an eye mask.

Background Art

[0002] Conventionally, there has been known a heating device that imparts a warming sensation to the eyes and the surrounding areas of the wearer by heating elements provided in the left-eye covering portion and the right-eye covering portion of the mask body (see Patent Document 1 and the like). In the heating device described in Patent Document 1, an upper slit extending downward from the upper edge of the mask body and a lower slit extending upward from the lower edge of the mask body are formed at the center in the left-right direction of the mask body. Thereby, when the wearer wears the heating device, the vicinity of the upper slit of the mask body narrows inward in the left-right direction of the mask body, and the vicinity of the lower slit of the mask body spreads outward in the left-right direction of the mask body, so that the heating device fits around the wearer's eyes and the surrounding areas of the eyes.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the heating device described in Patent Document 1, when the vicinity of the upper slit of the mask body narrows inward in the left-right direction of the mask body, the portion above the lower slit and between the respective heating elements of the mask body folds forward and floats, and a gap is formed between the vicinity of the root of the wearer's nose and the upper end portion of the nasal dorsum. Thus, in the heating device described in Patent Document 1, there is room for improvement from the viewpoint of suppressing the formation of a gap between the vicinity of the root of the wearer's nose and the upper end portion of the nasal dorsum and improving the fitting property of the heating device.

[0005] The present invention relates to an eye mask having a functional element that can prevent gaps from forming between the eye mask and the wearer near the bridge of the nose or the upper end of the nasal bridge. [Means for solving the problem]

[Figure 6] This figure shows the state of wearing the eye mask according to this embodiment. [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 provided on both the left and right ends of the main body portion 10.

[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 first imaginary line VL1 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 first imaginary line VL1. 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 first imaginary line VL1 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] Note that the shape of the main body 10 is not limited to this. For example, at least one of the upper edge portion 11 and the lower edge portion 12 may be formed in a linear shape extending along the left - right direction, or 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 downward toward the center in the left - right direction of the main body 10, or at least one of the upper edge portion 11 and the lower edge portion 12 may be locally protruding or curved, or the side edge portion 13 may be formed in a linear shape extending along the up - down direction, or the side edge portion 13 may be locally protruding or curved, or at least one of the upper edge portion 11 and the side edge portion 13 and at least one of the lower edge portion 12 and the side edge portion 13 may be orthogonal, or it may have various other known shapes.

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

[0018] The upper through - hole 14 is formed by a pair of upper inner edge portions 16 that are connected to each other at the lower end portions and whose upper end portions are configured to be able to approach or separate from each other. Specifically, the upper through - hole 14 is an upper notch defined by a pair of upper inner edge portions 16 that extend from the upper edge portion 11 toward the first virtual line VL1. Note that the upper through - hole 14 may be an upper cut extending from the upper edge portion 11 to the lower edge portion 12.

[0019] The upper inner edge portion 16 has a first upper inner edge portion 16a that extends from the upper edge portion 11 to the lower edge portion 12, and a second upper inner edge portion 16b that extends from the lower end of the first upper inner edge portion 16a toward the center in the left - right direction and the lower edge portion 12 of the main body 10. The first upper inner edge portion 16a is formed to be curved toward the center in the left - right direction of the main body 10. The second upper inner edge portion 16b is formed to be inclined from the lower end of the first upper inner edge portion 16a toward the first virtual line VL1.

[0020] The inclination angle of the second upper inner edge portion 16b is preferably 20° or more, more preferably 30° or more, and still more preferably 40° or more, from the viewpoint of facilitating the folding of the folding region BA (described later) of the eye mask 1 to the front side. Further, the inclination angle is preferably 70° or less, more preferably 60° or less, and still more preferably 45° or less, from the viewpoint of suppressing the upward floating of the portion MP between the upper through-hole 14 and the lower through-hole 15 of the main body portion 10 to the front.

[0021] In this specification, the "inclination angle of the second upper inner edge portion 16b" is an angle θ formed by a second virtual line VL2 passing through the upper end and the lower end of the second upper inner edge portion 16b and a third virtual line VL3 passing through the lower end of the second upper inner edge portion 16b in the left-right direction, as shown in FIG. 3.

[0022] A concave portion 16c that is recessed toward the outside in the left-right direction of the main body portion 10 is formed in the upper inner edge portion 16. The concave portion 16c is formed by the lower end portion of the first upper inner edge portion 16a and the upper end portion of the second upper inner edge portion 16b, and is formed in an angular shape as a whole. In other words, the concave portion 16c is a corner portion formed by the lower end portion of the first upper inner edge portion 16a and the upper end portion of the second upper inner edge portion 16b.

[0023] The vertical length L1 of the upper through-hole 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 portion 10, from the viewpoint of shortening the portion MP between the upper through-hole 14 and the lower through-hole 15 of the main body portion 10 and suppressing the upward floating due to the bending of the portion MP to the front. Further, 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, from the viewpoint of maintaining the strength of the eye mask 1.

[0024] In this specification, "the vertical length L1 of the upper through portion 14" refers to the length along the vertical direction from the upper end to the lower end of the upper inner edge portion 16, as shown in Figure 3. "The vertical length L2 of the main body portion 10" refers to the length along the vertical direction from the upper edge portion 11 to the lower edge portion 12, as shown in Figure 1. If the upper edge portion 11 is not formed in a straight line extending in the left-right direction, the tangent line along the left-right direction of the upper edge portion 11 is used as the reference. Similarly, if the lower edge portion 12 is not formed in a straight line extending in the left-right direction, the tangent line along the left-right direction of the lower edge portion 12 is used as the reference.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] The lower through-section 15 is formed by a pair of lower inner edge portions 17 that are connected to each other at their upper ends and whose lower ends are configured to move closer to or further apart from each other. Specifically, the lower through-section 15 is a lower notch defined by a pair of lower inner edge portions 17 that extend from the lower edge portion 12 toward the first virtual line VL1. The fact that the lower through-section 15 is a lower notch can further suppress the forward lifting of the portion MP between the upper through-section 14 and the lower through-section 15 of the main body portion 10. The lower through-section 15 may also be a lower cutout extending from the lower edge portion 12 toward the upper edge portion 11.

[0032] 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 shortening the portion MP between the upper through-hole 14 and the lower through-hole 15 of the main body 10 and suppressing the forward lifting of said portion MP. 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] [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.

[0047] 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 upper through portion 14 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 first virtual line VL1.

[0048] 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.

[0049] 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.

[0050] The separation distance D1 between the first virtual line VL1 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.

[0051] In this specification, "the distance D1 between the first virtual line VL1 and the functional body 20" is the distance along the left-right direction from the first virtual line VL1 to the end of the functional body 20 on the side of the first virtual line VL1, as shown in Figure 1. If the end of the functional body 20 on the side of the first virtual line VL1 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 side of the first virtual line VL1 is used as the reference.

[0052] 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.

[0053] 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 1. 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.

[0054] [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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] The ear hook portion 30, having the above configuration, is attached to both the left and right ends of the main body portion 10. Specifically, the ear hook portion 30 is attached at an angle downward with respect to the left and right direction of the main body portion 10, 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.

[0059] 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.

[0060] In this embodiment, the main body 10 and the ear hook portion 30 have been described as being separate components, but the invention is not limited to this, and the main body 10 and the ear hook portion 30 may be integrally formed.

[0061] [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.

[0062] 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 4, and provides the wearer with a warming or cooling sensation.

[0063] [Advantages of the eye mask according to this embodiment] As described above, the eye mask 1 according to this embodiment is an eye mask comprising 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 provided on both the left and right ends of the main body portion 10. The main body portion 10 has an upper through portion 14 in the left-right central part of the main body portion 10 that extends from the upper edge portion 11 to the lower edge portion 12 of the main body portion 10 and penetrates the main body portion 10 in the front-rear direction. The upper through portion 14 is formed by a pair of upper inner edge portions 16 that are connected to each other at their lower ends and whose upper ends are configured to move closer to or further apart from each other. Each of the pair of upper inner edge portions 16 has a recess 16c that is concave in the left-right direction. The functional body 20 is provided on the main body portion 10 such that at least a part of it is located between the upper through portion 14 and at least one of the ear loops 30.

[0064] With the eye mask 1 having this configuration, a recess 16c is formed on the upper inner edge 16. As the upper inner edge 16 narrows inward in the left-right direction, only the folding region BA (see Figure 5(a)) defined by the pivot center O of the eye mask 1 and the recess 16c folds forward, and the area near the upper inner edge 16 of the main body 10 does not fold forward but overlaps with each other (see Figure 5(b)). Therefore, when a wearer puts on the eye mask 1, as shown in Figure 6, the area near the upper inner edge 16 of the main body 10 does not fold forward and float, and gaps are less likely to form between the eye mask 1 and the area near the bridge of the nose or the upper end of the nose. As a result, the main body 10 can be made to fit snugly around the wearer's eyes when the eye mask 1 is worn, thereby improving the effectiveness of the functional body provided to the wearer.

[0065] In the eye mask 1 according to this embodiment, the upper inner edge portion 16 has a first upper inner edge portion 16a extending from the upper edge portion 11 toward the lower edge portion 12, and a second upper inner edge portion 16b extending from the lower end of the first upper inner edge portion 16a toward the left-right center of the main body portion 10 and toward the lower edge portion 12, and the recess 16c is formed by the lower end of the first upper inner edge portion 16a and the upper end of the second upper inner edge portion 16b. With the eye mask 1 having such a configuration, because it has a recess 16c formed by the lower end of the first upper inner edge portion 16a and the upper end of the second upper inner edge portion 16b, the vicinity of the upper inner edge portion 16 of the main body portion 10 does not fold forward and float when the eye mask 1 is worn, and the formation of a gap between the eye mask 1 and the vicinity of the wearer's nose root or the upper end of the nose bridge can be suppressed.

[0066] In the eye mask 1 according to this embodiment, the first upper inner edge portion 16a is formed to curve toward the left-right center of the main body portion 10. With the eye mask 1 having such a configuration, when the upper inner edge portion 16 narrows inward in the left-right direction, each first upper inner edge portion 16a makes point contact and shifts back and forth, thereby suppressing the front-to-back bending of the area near the upper inner edge portion 16 of the main body portion 10, while guiding the areas near the upper inner edge portions 16 of the main body portion 10 to overlap.

[0067] 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 separated by a virtual line (first virtual line VL1) that 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 separated by the virtual line (first virtual line VL1). 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 bridge of the wearer's nose, and the upper inner edge 16 can be easily narrowed inward in the left-right direction, allowing the main body 10 to fit more snugly.

[0068] In the eye mask 1 according to this embodiment, the main body portion 10 has a lower through portion 15 that extends from the lower edge portion 12 to the upper edge portion 11 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 an eye mask 1 having such a configuration, when the wearer puts on the eye mask 1, the lower through portion 15 spreads outward in the left-right direction starting from the upper end, so that the portion MP between the upper through portion 14 and the lower through portion 15 of the main body portion 10 does not lift forward, and the fit of the eye mask 1 can be improved. In addition, since the wearer's nose is inserted into the lower through portion 15, it is possible to prevent the formation of a gap between the vicinity of the boundary between the wearer's nose and cheek and the eye mask 1.

[0069] [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.

[0070] In the embodiments described above, the main body 10 was described as having a lower through-hole 15, but it is not limited to this, and it does not have to have a lower through-hole 15.

[0071] It is clear from the claims that the above-mentioned modifications are included within the scope of the present invention.
