Description

[Technical Field]

[0001] This invention relates to an eye mask that does not contain a heating or cooling device and is worn on the face to cover the eyes and block external light during sleep or rest, and a method for manufacturing such an eye mask. [Background technology]

[0002] Generally, eye masks are required to be flat, compact, and highly portable when not in use, such as when stored, but three-dimensional and comfortable to wear when in use.

[0003] For example, Patent Document 1 discloses an ear-hook type eye mask in which the left and right blindfold sections are folded at a center fold line when overlapping (when not in use) (see Figure 22, etc.). According to Patent Document 1, the left and right storage width is narrowed, making it compact, but because the left and right ear hook sections (a pair of attachments) overlap front to back, pressure applied during storage can leave marks on the eye mask, potentially making it look unattractive.

[0004] Meanwhile, Patent Document 2 discloses a heated eye mask in which ear loops connected to the ends of the left and right blindfolds are integrated via a central perforation (see Figure 2, etc.). Patent Document 2 prevents the ear loops from leaving marks when the mask is stored. However, because the left and right ear loops are folded at both ends of the left and right blindfolds, the left and right storage width increases, hindering compactness. (Overlapping the blindfolds reduces the left and right width by half, but the blindfolds, including the heating element, have a double structure, which makes the mask look unattractive.) Furthermore, because the central perforations (vertical) of the left and right ear loops and the fold lines (diagonal) at both ends of the left and right blindfolds intersect diagonally, structural and manufacturing errors are likely to occur. When used as a non-heating type, the amount of expansion (expansion) of the blindfolds tends to be insufficient (not expanding) when in use (unfolded). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 7430959 [Patent Document 2] Patent No. 5028149 Summary of the Invention [Problem to be solved by the invention]

[0006] The object of the present invention is to provide an eye mask that can be quickly converted from a good-looking, compact, and conveniently folded form to a comfortable, usable form by separating the fitting body along the planned tear line, and a method for manufacturing an eye mask that is less prone to structural and manufacturing errors and is suitable for mass production.

[0007] In order to solve the above problems, the first eye mask of the present invention is An eye mask comprising: a horizontally elongated main body with blindfold sections formed on either side of a central nose pad; and an attachment body with ear loops connected to the ends of each blindfold section, the attachment body being joined together along a vertical planned tear line at the rear side of the main body, which is in the direction of the face when viewed from the main body; In an overlapping configuration in which each of the blindfold parts does not include a heating or cooling device and is folded together with the attachment body toward the nose pad part at a vertical fold line located at the horizontal middle of the blindfold part, the left and right ends of the main body are provided with an upper fused part that is heat-sealed to each other from the intersection of the fold line and the upper outline line downwards, a lower fused part that is heat-sealed to each other from the intersection of the fold line and the lower outline line upwards, and a non-fused part that is located between the upper fused part and the lower fused part and is not heat-sealed to each other, and are arranged in a row along the inside of the fold line; In the overlapping configuration, when viewed from behind, the attachment body is positioned in front, the planned breaking line of the attachment body and the folding lines of the left and right blindfolding portions are arranged parallel to each other along the vertical direction, When the attachment is separated into left and right parts along the intended break line during use, each of the ear hook portions unfolds laterally together with the corresponding blindfold portion, and when each of the blindfold portions unfolds together with the ear hook portion from the fold line and spreads outward laterally, the upper fused portion and the lower fused portion are folded so as to approach each other on the fold line with the non-fused portion in between, resulting in a bulging shape that protrudes toward the front of the face as a whole.

[0008] In this way, when viewed from the back in the overlapping form, the planned breaking line for dividing the attachment into left and right ear loops and the left and right fold lines located in the horizontal middle of the blindfold are arranged parallel to each other along the vertical direction, so that when the attachment is separated along the planned breaking line to divide it into left and right ear loops and the left and right ear loops are unfolded horizontally, the left and right blindfolds protrude forward in front of the face. This allows for quick transition from a compact, attractive, and conveniently stored folded form to a comfortable, usable form.

[0009] Specifically, if upper and lower fused sections are formed in each overlapping blindfold section, and the left and right blindfold sections are unfolded from the fold line and spread out laterally during use, the blindfold sections will bend easily so that the upper and lower fused sections approach each other on the fold line, starting from the unfused section (because the upper and lower middle sections including the non-fused sections spread widely toward both ends, while the upper and lower sections including the heat-fused sections spread less than the middle section), and the entire mask will bulge out in front of the face. This makes it possible to achieve an eye mask that has a good-looking and compact structure, while the blindfold sections bulge out sufficiently during use, providing excellent wearing comfort.

[0010] Furthermore, since the planned breaking line and the left and right folding lines are arranged parallel to each other along the vertical direction, structural and manufacturing errors are unlikely to occur.

[0011] The planned tear line is composed of a cut line portion (slit portion) and a non-cut line portion (ground portion), and cut lines (slits) of unequal lengths are sometimes called "tear lines" and cut lines (slits) of approximately equal lengths (for example, the difference between the maximum and minimum lengths is within 10%) are sometimes called "perforations." Planned tear lines may also include, in addition to tear lines and perforations, easily tearable portions (portions that are easily torn, such as in straight-cut films), opening designation portions (slit portions that indicate the opening start position, such as V-notches), auxiliary tape attachment portions (portions where cutting guide tape is attached), etc.

[0012] When viewed from behind in the above-mentioned overlapping form, the left and right ends of the attachment body are each connected to the corresponding blindfold portion via an expansion portion that includes one or more pleats along the vertical direction and is stretchable in the front-to-back direction like a gusset or bellows.

[0013] In this way, the length of the ear hook portion can be easily adjusted by expanding and contracting the expanding portion, improving the wearing comfort during use.

[0014] However, if the attachment has greater stretchability (especially in the lateral direction) than the main body and is made of a soft, elastic material, such an expandable section is not necessarily required. In this case, the attachment is pulled laterally in the unfolded state and stretched to allow ear hooking, and in the folded state it shrinks to a predetermined width.

[0015] The left and right expanded portions are formed as pleats (folds) entirely on the lateral side of the upper and lower fused portions located at the left and right ends.

[0016] As a result, when the containers are stacked, the expanding portion is located inside (within the width of) the upper and lower fused portions and does not protrude outward, making it easier to individually wrap, store, and take out.

[0017] The longitudinal planned breaking line located in the lateral middle portion of the wearing body coincides in the front-rear direction with the longitudinal nose center line located in the lateral center portion of the nose pad.

[0018] In this way, even first-time users can immediately use the product by separating the left and right attachment parts along the planned tear line and unfolding the left and right ear hook parts laterally. The product is also suitable for mass production as it is less susceptible to structural and manufacturing errors.

[0019] In order to solve the above problems, the first method of manufacturing an eye mask of the present invention comprises: A method for manufacturing an eye mask comprising: a horizontally elongated main body with blindfold sections formed on either side of a central nose pad; and an attachment body, which is connected to the end of each blindfold section to form ear loops, and which is integrally joined to the main body at the rear side, which is in the direction of the face when viewed from the main body, via a planned vertical tear line (e.g., a perforation), a joining step of joining the main body and the attachment at the left and right ends of the blindfold part, in a state where the main body is made of a single layer or multiple layers of fabric, the attachment body is made of a single layer or multiple layers of fabric and has a pair of ear holes formed through the ear hook part or a pair of planned cutting lines contoured to become the ear holes when in use, and the planned breaking line, and the attachment body is located on the rear side of the main body and overlaps with the vertical nose center line located in the horizontal center of the nose pad part so that the planned breaking lines coincide in the front-to-back direction; a folding step in which each of the blindfold parts does not include a heating or cooling device, and is folded together with the attachment body toward the nose pad part at a vertical fold line that is located in the horizontal middle of the blindfold part and is arranged parallel to the intended breaking line; a heat-sealing step of simultaneously forming, in a line along the inside of the fold line, an upper fused portion that heat-seals the overlapping portions downward from the intersection of the fold line and the upper outline line, a lower fused portion that heat-seals the overlapping portions upward from the intersection of the fold line and the lower outline line, and a non-fused portion that is located between the upper fused portion and the lower fused portion and does not heat-seal the overlapping portions; The present invention is characterized by comprising: In order to solve the above problems, the second method of manufacturing an eye mask of the present invention is to A method for manufacturing an eye mask comprising: a horizontally elongated main body with blindfold sections formed on either side of a central nose pad; and an attachment body having ear loops connected to the ends of each blindfold section, the ear loops being formed respectively, and the main body being joined together at the rear side, which is in the direction of the face as viewed from the main body, via a planned longitudinal tear line; a first heat-sealing step in which a single-layer or multi-layer fabric body material, which is continuous in the vertical direction over a predetermined width, is placed behind a single-layer or multi-layer fabric body material, which is continuous in the vertical direction over approximately the same width as the main body material, and the left and right edges in the horizontal direction are heat-sealed continuously over a predetermined width to form an eye mask body material having a multi-layer structure of the main body material and the body material; The eye mask material is presumed to have a plurality of markings drawn by repeatedly transferring the main body of the eye mask onto the main body material in the vertical direction, and a pair of ear loop holes formed through the ear loop portion of the attachment material or a pair of planned cutting lines contoured to become the ear loop holes when in use, and the planned breaking lines, repeatedly formed in the vertical direction, and the upper outline of one of the adjacent markings faces the lower outline of the other (specifically, they are in contact (i.e., coincident) or face each other with a slight gap between them), thereby connecting the eye mask material in the vertical direction; and a first cutting process in which the eye mask material is continuously cut in the vertical direction so as to include the left outline and right outline of each of the connecting markings, thereby forming a continuous eye mask body. a folding step in which each of the blindfold portions of each of the score lines of the eye mask continuum is folded toward the nose pad portion along a longitudinal fold line that is located in the horizontal middle of the blindfold portion and parallel to the intended tear line, together with the attachment material; a second heat-sealing step for simultaneously forming, in a line along the inside of the fold-back line, an upper fused portion for heat-sealing the overlapping portions of each of the score lines of the eye mask continuum, the fold-back line being an upper inclined line that approaches the nose pad portion as it approaches the intersection position of the fold-back line and the upper outline line when it moves downward from the intersection position of the fold-back line and the lower outline line, a lower fused portion for heat-sealing the overlapping portions of each of the score lines of the eye mask continuum, the fold-back line being a lower inclined line that approaches the nose pad portion as it moves upward from the intersection position of the fold-back line and the lower outline line when it moves upward from the intersection position of the fold-back line and the lower outline line, and a non-fused portion located between the upper fused portion and the lower fused portion and not heat-sealing the overlapping portions of each of the score lines of the eye mask continuum; a second cutting step of cutting each of the score lines of the continuous eye mask along the outer sides of the upper inclined line and the lower inclined line in the vicinity of the upper outline and the lower outline of the folding line, and cutting adjacent score lines of the continuous eye mask together with the wearing body material at the upper outline and the lower outline to separate the continuous eye mask into individual eye masks; The present invention is characterized by comprising:

[0020] As described above, in the folding process, the planned breaking line and the left and right fold lines are arranged parallel to each other along the vertical direction, so structural and manufacturing errors are unlikely to occur and the product is suitable for mass production. In the joining process, the main body and the attachment body are joined by various means such as heat fusion, adhesive, or sewing.

[0021] In the folding process, one or more pleats (pleats / creases) are formed in the attachment body along the vertical direction at a location other than the joint with the blindfold part, symmetrically and simultaneously on both sides of the planned tear line, and these become expansion parts that can expand and contract in the front-to-back direction like gussets or accordions, and are each connected to the corresponding blindfold part.

[0022] In this way, since the expanding portion is expandable and contractible, pleats can be easily formed in the ear hook portion during the folding process.

[0023] The left and right expansion portions are provided as pleats (folds) on the lateral side of the upper and lower fused portions located at the left and right ends.

[0024] This allows the expanded portion to be located inside (within the width of) the upper and lower fused portions when overlapped, and does not protrude outward, making it easy to create pleats in the ear loops during the folding process. Furthermore, the expanded portion does not interfere with the creation of the fused portions during the heat-sealing process, contributing to the smooth production of eye masks with excellent fit.

[0025] In order to solve the above problems, the second eye mask of the present invention is An eye mask comprising a horizontally elongated main body with blindfold sections formed on either side of a central nose pad, and an attachment body connected to the ends of each blindfold section and positioned rearward in the direction of the face, In the main body, in an overlapping state in which each of the blindfold parts does not include a heating or cooling device and is folded together with the attachment toward the nose pad part at a vertical fold line located at a horizontally intermediate portion thereof, at the left and right ends, there are arranged in a line along the inside of the fold line an upper fused part that is heat-sealed to each other at an overlapping portion downward from an intersection of the fold line and an upper outline line, a lower fused part that is heat-sealed to each other at an overlapping portion upward from an intersection of the fold line and a lower outline line, and a non-fused part that is located intermediate the upper fused part and the lower fused part and is not heat-sealed to each other at an overlapping portion, The wearing body is formed in such a way that the left and right ear hook parts respectively connected to the end sides of the blindfold parts are integrally connected via a vertical planned breaking line that allows separation into left and right parts, and in the overlapping form, the ear hook parts are folded toward the horizontal center of the folded main body so as not to overlap with the upper fused part and the lower fused part, When the attachment is separated into left and right parts along the intended break line during use, each of the ear hook portions unfolds laterally together with the corresponding blindfold portion, and when each of the blindfold portions unfolds together with the ear hook portion from the fold line and spreads outward laterally, the upper fused portion and the lower fused portion are folded so as to approach each other on the fold line with the non-fused portion in between, resulting in a bulging shape that protrudes toward the front of the face as a whole.

[0026] In order to solve the above problems, a third method for producing an eye mask of the present invention comprises: A method for manufacturing an eye mask comprising: a horizontally elongated main body with blindfold sections formed on either side of a central nose pad; and an attachment body having ear loops connected to the ends of each blindfold section, the ear loops being formed respectively, and the main body being joined together at the rear side, which is in the direction of the face as viewed from the main body, via a planned longitudinal tear line; a joining step of joining the main body and the attachment at the left and right ends of the blindfold part, in a state where the main body is made of a single layer or multiple layers of fabric, the attachment body is made of a single layer or multiple layers of fabric and has a pair of ear holes formed through the ear hook part or a pair of planned cutting lines contoured to become the ear holes when in use, and the planned breaking line, and the attachment body is located on the rear side of the main body and overlaps with the vertical nose center line located in the horizontal center of the nose pad part so that the planned breaking lines coincide in the front-to-back direction; a folding step in which each of the blindfold parts does not include a heating or cooling device and is folded toward the nose pad part along a vertical folding line located in the middle of the blindfold part in the horizontal direction together with the attachment; a heat-sealing step of simultaneously forming, in a line along the inside of the fold line, an upper fused portion that heat-seals the overlapping portions downward from the intersection of the fold line and the upper outline line, a lower fused portion that heat-seals the overlapping portions upward from the intersection of the fold line and the lower outline line, and a non-fused portion that is located between the upper fused portion and the lower fused portion and does not heat-seal the overlapping portions; In the folding step, the attachment body is folded toward the center in the lateral direction of the folded main body relative to the upper fused portion and the lower fused portion so as not to overlap with the upper fused portion and the lower fused portion. In order to solve the above problems, a fourth method of manufacturing an eye mask of the present invention comprises: A method for manufacturing an eye mask comprising: a horizontally elongated main body with blindfold sections formed on either side of a central nose pad; and an attachment body having ear loops connected to the ends of each blindfold section, the ear loops being formed respectively, and the main body being joined together at the rear side, which is in the direction of the face as viewed from the main body, via a planned longitudinal tear line; a first heat-sealing step in which a single-layer or multi-layer fabric body material, which is continuous in the vertical direction over a predetermined width, is placed behind a single-layer or multi-layer fabric body material, which is continuous in the vertical direction over approximately the same width as the main body material, and the left and right edges in the horizontal direction are heat-sealed continuously over a predetermined width to form an eye mask body material having a multi-layer structure of the main body material and the body material; The eye mask material is presumed to have a plurality of markings drawn by repeatedly transferring the main body of the eye mask onto the main body material in the vertical direction, and a pair of ear loop holes formed through the ear loop portion of the attachment material or a pair of planned cutting lines contoured to become the ear loop holes when in use, and the planned breaking lines, repeatedly formed in the vertical direction, and the upper outline of one of the adjacent markings faces the lower outline of the other (specifically, they are in contact (i.e., coincident) or face each other with a slight gap between them), thereby connecting the eye mask material in the vertical direction; and a first cutting process in which the eye mask material is continuously cut in the vertical direction so as to include the left outline and right outline of each of the connecting markings, thereby forming a continuous eye mask body. a folding step in which each of the blindfold portions of the eye mask continuum is folded toward the nose pad portion along a vertical fold line located in the horizontal middle of the blindfold portion, without including a heating or cooling device, together with the attachment material; a second heat-sealing step for simultaneously forming, in a line along the inside of the fold-back line, an upper fused portion for heat-sealing the overlapping portions of each of the score lines of the eye mask continuum, the fold-back line being an upper inclined line that approaches the nose pad portion as it approaches the intersection position of the fold-back line and the upper outline line when it moves downward from the intersection position of the fold-back line and the lower outline line, a lower fused portion for heat-sealing the overlapping portions of each of the score lines of the eye mask continuum, the fold-back line being a lower inclined line that approaches the nose pad portion as it moves upward from the intersection position of the fold-back line and the lower outline line when it moves upward from the intersection position of the fold-back line and the lower outline line, and a non-fused portion located between the upper fused portion and the lower fused portion and not heat-sealing the overlapping portions of each of the score lines of the eye mask continuum; a second cutting step of cutting each of the score lines of the continuous eye mask along the outer sides of the upper inclined line and the lower inclined line in the vicinity of the upper outline and the lower outline of the folding line, and cutting adjacent score lines of the continuous eye mask together with the wearing body material at the upper outline and the lower outline to separate the continuous eye mask into individual eye masks; In the folding step, the attachment material is folded toward the center of the folded main body material in the horizontal direction relative to the upper fused portion and the lower fused portion so as not to overlap the upper fused portion and the lower fused portion.

[0027] As a result, when folded in a stacked configuration, the upper and lower fused portions of the main body and the attachment are not overlapped, allowing the upper and lower fused portions to be formed while the attachment is still attached to the main body. This allows for smooth manufacturing of eye masks. However, in this case, the attachment may require a complex folding process in which the folded main body is folded toward the horizontal center so that the upper and lower fused portions do not overlap. In contrast, the attachment configured as described above has both left and right ends joined to both left and right ends of the main body, and the left and right ear loops are integrally connected via a planned break line. This significantly restricts the movement of the attachment, making it easy to control that movement and facilitating the folding process of centering the attachment relative to the main body. This restriction also makes it easy to maintain the folded state. When the left and right ear loops are separated, the sides of each ear loop opposite to the side joined to the main body are unconstrained, making it difficult to control their movement and making the folding process difficult. Furthermore, due to the presence of unconstrained portions, it is difficult to maintain the folded state.

[0028] In addition, when overlapped, the expanded portion is located inside (within the width) of the blindfold portion (fold line) and does not protrude outward, making it easy to create pleats in the ear hook portion during the folding process. [Brief explanation of the drawings]

[0030] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0031] 1 to 7, the eye mask 100 of the first embodiment comprises a heat-sealable, horizontally elongated eye mask main body 1 (main body) with blindfold sections 1E, 1E formed on either side of the center (nose pads) in the horizontal direction Y (left-right direction), and a heat-sealable and stretchable wearing body 9 with left and right ear loop sections 91, 91 formed to connect to the left and right end sides (end sides of each blindfold section 1E, 1E), respectively, of the eye mask main body 1. As shown in Fig. 1, the user wears the eye mask 1 by hanging the ear loop sections 91, 91 over their ears and covering their eyes and the surrounding areas with the eye mask main body 1. Reference numeral 1a denotes the front surface of the eye mask main body 1, and reference numeral 1b denotes the back surface of the eye mask main body 1 (the side facing the eyes when worn by the user).

[0032] The eye mask body 1 (main body) is in an overlapping state (folded state: see Figures 5 and 6) in which each blindfold portion 1E, 1E does not contain a heating or cooling device and is folded toward the center in the horizontal direction Y (toward the nose pad portion 1N) at a fold line 4 in the vertical direction Z (up and down direction) located in the middle of the horizontal direction Y (left and right direction). At the left and right ends, there are an upper fused portion 2A that is heat-sealed to each other from the intersection of the fold line 4 and the upper outline line 1u downwards, a lower fused portion 2B that is heat-sealed to each other from the intersection of the fold line 4 and the lower outline line 1d upwards, and a non-fused portion 3 that is located halfway between the upper fused portion 2A and the lower fused portion 2B and is not heat-sealed to each other. These are arranged in a row along the inside of the fold line 4.

[0033] 5, in the overlapping configuration, the fold line 4 is cut in an inclined line 4t in the region near the upper outline 1u and the lower outline 1d so as to approach the horizontal center (the nose pad 1N side) as it approaches the intersection point. The upper fused portion 2A and the lower fused portion 2B are formed on the inside along the inclined line 4t of the fold line 4.

[0034] Figure 7 is a view of the eye mask main body 1 (main body) unfolded with the upper fused portion 2A and the lower fused portion 2B unbonded. The left ear loop portion 91 is not shown, but is formed symmetrically with the right ear loop portion 91. As shown in Figure 7, the upper outline 1u is formed in a curved shape that is slightly convex upward at the center in the horizontal direction Y (above the nose pad portion 1N). Conversely, the lower outline 1d is formed in a curved shape that is slightly concave upward at the center in the horizontal direction Y (above the nose pad portion 1N).

[0035] The upper and lower outer contour lines 1u and 1d overlap each other in the overlapping state (see FIG. 5) at both lateral sections centered on the folding line 4 in the lateral direction Y.

[0036] The eye mask body 1 also has a left outline 1l and a right outline 1r that connect the upper outline 1u and the lower outline 1d on the left and right sides in the vertical direction Z. The left outline 1l and the right outline 1r are inclined (curved or arc-shaped in this case) on both outer sides in the vertical direction Z, protruding outward in the horizontal direction Y as they approach the center in the vertical direction Z, while at the center in the vertical direction Z they are linear and extend in the vertical direction Z, with the vertical center section being the left and right outermost edges of the eye mask body 1.

[0037] A nose pad portion 1N is formed in the center of the eye mask body 1. The nose pad portion 1N is cut out from the lower outline 1d upward (see FIG. 5).

[0038] The nose pads 1N may simply have cut lines formed thereon. For example, the nose pads 1N may have cut lines extending in the vertical direction Z (upward) from the lower end of the eye mask body 1 at the center thereof.

[0039] When not in use, the eye mask body 1 is in an overlapping configuration as shown in Figures 5 and 6. When in use, the eye mask body 1 has the body end portions 1S, 1S (body folded portions) that are outside the left and right fold lines 4, 4 (see Figures 5 and 6), and when not in use, the eye mask body 1 is in an overlapping configuration in which the body end portions 1S, 1S are overlapping with the body central portion 1C that is inside the fold lines 4, 4 (see Figures 1 to 4). In this overlapping configuration, the body end portions 1S, 1S do not overlap with each other.

[0040] The sheet material (surface-shaped member) that constitutes the eye mask main body 1 (main body) can be a single-layer or multi-layer fabric (nonwoven fabric, sponge, urethane, etc.) stacked together, or a laminated material made of these. Here, the eye mask main body 1 is formed as a laminated sheet body with multiple overlapping sheet materials. Each sheet material has a specific function, such as a decorative sheet, a flexible sheet, or a light-blocking sheet, and by stacking them, the eye mask main body 1 with its individual function can be formed. Each sheet material can be a heat-sealable material that can be melted and welded by heat treatment (heat-sealable material: in this case, primarily nonwoven fabric made of thermoplastic resin). Note that when the eye mask is made of multi-layered sheet materials, any material that can be ultimately integrated by heat fusion may be used. Other sheet materials (other than the heat-sealable material) may also be included within the multi-layered sheet material.

[0041] In the overlapping configuration (when unused) shown in FIGS. 5 and 6 , the wearing body 9 has an ear-hook forming section 90 formed by joining left and right ear hook sections 91, 91 together in the horizontal direction Y along a vertical perforation line 9C (planned tear line) at the rear side (opposite direction F) that faces the face when viewed from the eye mask main body 1. The wearing body 9 also has ear-hook connecting sections 92, 92 at both ends of the ear-hook forming section 90, which connect to the eye mask main body 1. The left and right ear hook sections 91, 91 are connected to the eye mask main body 1 by the corresponding ear-hook connecting section 92. As shown in FIG. 7 , the ear-hook connecting sections 92, 92 here overlap the outermost edge regions of the eye mask main body 1 on the left and right sides, which extend linearly in the vertical direction Z. Heat-sealed sections 2s, 2s extending linearly in the vertical direction Z are formed at both ends of the main body, and the ear-hook connecting sections 92 are joined to the eye mask main body 1 in a manner that minimizes the width in the horizontal direction Y.

[0042] In the overlapping form, the attachment body 9 (ear hook forming portion 90) is folded toward the center (biased toward the center) so as not to overlap with the end regions L, L in the horizontal direction Y where the upper fused portion 2A, the lower fused portion 2B, and the non-fused portion 3 are formed in a row in the eye mask main body 1 (see Figure 6).

[0043] Specifically, the left and right end sides of the wearing body 9 (ear loop forming portions 90) in the overlapping form have one or more pleats (pleats / folds: f1, f2, f3) along the vertical direction Z, and are connected to the ear loop connecting portions 92 at each end via expansion portions 95 that are stretchable in the front-to-back direction (front direction F) like gussets or accordions, and are connected to the ends of the corresponding blindfold portions 1E (the left and right outermost edge regions of the eye mask main body 1) by the ear loop connecting portions 92 (see Figure 6).The left and right expansion portions 95 are formed as pleats that are entirely closer to the horizontal center than the fused portions 2A and 2B located at the left and right ends.

[0044] The perforation line 9C (proposed tear line) extends in the vertical direction Z at the center position in the horizontal direction Y of the eye mask body 1 in the overlapped state (see FIG. 5).

[0045] Here, the perforation line 9C (planned tear line) is arranged parallel to the fold lines 4, 4 of the left and right blindfold portions 1E, 1E in the overlapping form when viewed from behind with the attachment body 9 positioned in front (see Figure 5).

[0046] In addition, the perforation line 9C (planned break line) here is located in the middle part (middle part in the horizontal direction) of the attachment body 9 in the overlapping form, and coincides in the front-to-back direction (forward direction F) of the face with the nose center line 1n in the vertical direction Z (see Figure 5) located in the center part (center part in the horizontal direction) in the horizontal direction Y of the nose pad portion 1N in the vertical direction Z (see Figure 5).

[0047] The wearing body 9 is made of a stretchable sheet material, here a single-layer (or multiple-layer) fabric, made of a stretchable material (such as a stretchable nonwoven fabric) that is thinner and more flexible than the material of the eye mask body. Furthermore, this stretchable material is also a heat-sealable material that can be melted and welded by heat treatment. Each of the left and right ear loops 91 has a perforation line 9E in the center that allows for the formation of ear loop holes 9H for ear looping.

[0048] The perforation line 9E is circular here, but may be linear.

[0049] When not in use, the ear hook forming portion 90 may have ear hook holes 9H instead of the perforation lines 9E.

[0050] When using the eye mask 100, the attachment body 9 is separated into left and right halves along the perforation line 9C (the intended tear line). At this time, each of the ear loop portions 91, 91 unfolds in the horizontal direction Y together with the corresponding blindfold portions 1E, 1E. Furthermore, as shown in FIGS. 2 to 4, each of the blindfold portions 1E, 1E unfolds from the fold line 4 together with the ear loop portions 91, 91, and is pulled and spread outward in the horizontal direction Y. As a result, the left and right main body end portions 1S, 1S (main body folded portions) are spread outward from the left and right fold lines 4, 4, while the upper fused portion 2A and the lower fused portion 2B are folded toward each other on the fold line 4 with the non-fused portion 3 in between, resulting in a bulging shape (protruding shape: see FIG. 3) that protrudes toward the front F of the face as a whole.

[0051] A method for changing the eye mask 100 from an unused state (folded state) to a usable state (opened state) will be described with reference to FIGS. 8 to 11. FIG.

[0052] When the eye mask 100 is not in use, the left and right ear loop portions 91, 91 of the attachment body 9 are connected in the horizontal direction Y across the perforation line 9C, forming an ear loop forming portion 90. The attachment body 9 is connected to the eye mask main body 1 by heat fusion (2s, 2s) at the ear loop connecting portions 92, 92 on both ends in the horizontal direction Y (Figs. 5 and 6).

[0053] When using the eye mask 100, first, the perforation line 9C of the ear loop forming portion 90 is cut off (Fig. 6 → Fig. 8). This separates the ear loop forming portion 90 into left and right halves, forming separate left and right ear loop portions 91, 91. Next, the perforation lines 9E, 9E are cut off (not shown). This forms ear loop holes 9H (see Figs. 2 and 3) in each of the left and right ear loop portions 91, 91.

[0054] Next, the separated left and right ear loop portions 91, 91 are each pulled outward in the lateral direction Y. This causes the eye mask body to unfold in the order shown in Figures 9, 10, and 11, forming the bulging shape (protruding shape: Figure 11) that protrudes (projects) toward the front of the face F, and the eye mask is ready for use. In this state, the user can attach the eye mask to their face by hooking their ears into the ear loop holes 9H of the left and right ear loop portions 91, 91 (Figure 1).

[0055] In this expanded form during use (see Figures 2 to 4), the upper fused parts 2A and lower fused parts 2B located on the left and right sides of the eye mask body 1 are inclined toward the front F of the face toward the center in the vertical direction Z, and this inclined shape does not collapse. In this state, the lower ends of the left and right upper fused parts 2A and the upper ends of the lower fused parts 2B are positioned toward the front F of the face to form a peak. Then, the central region of the eye mask body 1, surrounded by the lower ends of the left and right upper fused parts 2A and the upper ends of the lower fused parts 2B, curves in a way that bulges slightly toward the front F of the face, with the lower ends of the left and right upper fused parts 2A and the upper ends of the lower fused parts 2B as base points.

[0056] When worn by a user as shown in Figure 1, the left and right fold lines 4, 4 of the eye mask main body 1 are located near eye positions E, E, which correspond to the left and right eye positions (including the outer corners of the eyes) of the user wearing the eye mask (see Figure 1). This ensures that the user's eyes (including the outer corners of the eyes) are located behind the position where the eye mask main body 1 protrudes forward F into a three-dimensional form. In Figure 1, the symbol E is a line indicating the eye position in the horizontal direction Y (left-right direction), the symbol N is a line indicating the nose position in the left-right direction Y, and the line N is a line located midway between the two lines E, E in the horizontal direction Y.

[0057] A method for manufacturing the eye mask 100 will be described with reference to FIGS.

[0058] It should be noted that lines 1y, 2x, 9y, 9c, 9e, 2ys, 2yt, 3x, 4x, and 5x1 to 5x3 are all imaginary lines indicating planned processing positions and do not actually exist.

[0059] First, the eye mask manufacturing apparatus performs the main body sheet forming process. In this process, as shown in FIG. 12, continuous strip-shaped main body sheet materials 10a, 10b, 10c, and 10d are fed from multiple rolls, each with a predetermined width in the longitudinal direction Z. These strips are then stacked so that their longitudinal directions coincide, and the laminated main body sheet material 10 is transported (discharged) in its longitudinal direction (transport direction C). Note that the laminated main body sheet material 10 is assumed to have a continuous outline 1y (main body markings / markings) of the eye mask body 1 along the transport direction C (i.e., multiple markings are drawn by repeatedly transferring the eye mask body 1 longitudinally). In this process, the laminated main body sheet material 10 is sequentially formed with outline heat-sealed lines 2D corresponding to the continuous outline 1y (main body markings / markings) of each eye mask body 1 along the transport direction C. As a result, a strip-shaped main body sheet body 11 (main body material) in which a plurality of main body sheet materials 10a, 10b, 10c, 10d (multi-layer fabrics) are integrated by heat fusion (2D) is conveyed in the conveying direction C.

[0060] The outer heat-sealing lines 2D are formed by performing point or linear heat fusion along predetermined heat-sealing lines 2x corresponding to the outer lines 1y of each eye mask body 1, which are continuously set along the conveying direction C on the main laminated sheet material 10.

[0061] The intended heat-sealing lines 2x are basically set inside and along the outline 1y of each eye mask body 1, which is set continuously along the conveying direction C of the main laminated sheet material 10.

[0062] The intended heat-sealing lines 2x here are set so as to extend outward from the outline 1y only at both ends in the sheet width direction SY, and are set along the outline 1y on the inside of the outline 1y in the remaining section. That is, the intended heat-sealing lines 2x here have a shape in which the left and right outer edges (left and right outlines 1l, 1r) of the outline 1y extend outward in the sheet width direction SY. Specifically, the left and right outer edges (left and right outlines 1l, 1r) of the outline 1y extend linearly in the vertical direction Z (conveying direction C) in the central section in the vertical direction Z (conveying direction C), and the intended heat-sealing lines 2x are set in that central section so as to extend beyond the linear left and right outer edges outward in the sheet width direction SY.

[0063] In the heat-sealing process in the main body sheet forming process, a cylindrical embossing die (not shown) is pressed against the main laminate sheet material 10 fed in the conveying direction C in a predetermined first work section W1, and the main laminate sheet material 10 is pressurized and heated (heat-sealed or thermally welded) along a predetermined heat-sealing line 2x. Here, the main laminate sheet material 10 is heated by friction (e.g., ultrasonic welding, high-frequency welding, etc.) at the pressure positions applied by the embossing die. As a result, lines 2D (here, dot-like heat-sealed lines) of hardened heat-sealed portions (hardened portions) are formed in the main laminate sheet material 10 at each heated and pressed position, and the main body sheet materials 10a, 10b, 10c, and 10d are joined and integrated at the heat-sealed portions (2D). The integrated main body sheet materials 10a, 10b, 10c, and 10d are fed in the conveying direction C as a strip-shaped main sheet body 11.

[0064] When the main body sheet 11 is a single-layer main body sheet material, the main body sheet forming step can be omitted.

[0065] Simultaneously with the main body sheet forming process, the eye mask manufacturing apparatus also performs an ear loop sheet forming process. In this process, as shown in FIG. 13, a strip-shaped ear loop sheet material 20, which is continuous in the vertical direction Z and has approximately the same width as the main body sheet body 11 (main body material), is conveyed (carried out) in its longitudinal direction (conveying direction C) from a roll. It is assumed that the main body sheet body 11 (main body material) still has an outline 1y (main body crease / crease) of the eye mask main body 1 continuously set along the conveying direction C. Meanwhile, it is assumed that the ear loop sheet material 20 has an outline 9y (attaching body crease) of the wearing body 9, a pair of intended perforation lines 9e, 9e (intended cutting lines) contoured at predetermined positions within the outline 9y to form the ear loop holes 9H when in use, and an intended perforation line 9c (intended tear line) that divides the sheet into left and right halves when in use, continuously set along the conveying direction C. Then, perforation lines 9E, 9C, 9E corresponding to the intended perforation lines 9e, 9c, 9e are sequentially formed on the conveyed (conveyed) strip-shaped ear hook sheet material 20 inside the outline 9y (attachment markings) of each attachment 9 that are set continuously along the conveyance direction C. As a result, the ear hook sheet body 21 (attachment material) on which the perforation lines 9E, 9C, 9E have been formed is conveyed in the conveyance direction C.

[0066] The outline lines 1y (lined body of the eye mask body) of the eye mask body 1 and the outline lines 9y (lined body of the attachment body) of the attachment body 9 are set so that the shapes and arrangements of the strip-shaped main body sheet body 11 and the strip-shaped ear loop sheet body 21 are consistent in the longitudinal direction of each.

[0067] The perforation line 9C (left and right separation line) is formed by forming perforations on a predetermined intended perforation line 9c that extends continuously and linearly through the center of the sheet width along the conveying direction C of the ear hook sheet material 20. The perforation line 9C is formed as an intended tear line for separating the ear hook forming portion 90 (attachment body 9) into left and right ear hook portions 91, 91.

[0068] The perforation lines 9E, 9E (ear hole forming lines) are formed on predetermined perforation lines 9e, 9e inside the outline lines 9y (attachment markings) of the attachment 9, which are continuously set on the ear hooking sheet material 20 along the conveyance direction C. The perforation lines 9E, 9E are formed as a pair of cut-out lines contoured to form a pair of ear hook holes 9H, 9H that penetrate the pair of left and right ear hooking portions 91, 91. The perforation lines 9E, 9E here are set symmetrically on the left and right of the perforation line 9C.

[0069] It should be noted that the ear holes 9H themselves may be formed instead of forming perforation lines 9E, 9E as the intended cutting lines.

[0070] The perforation lines 9E, 9E may be formed linearly instead of circularly.

[0071] In the perforation forming process in the ear hook sheet body forming process, perforation lines 9E, 9C, 9E are formed along the intended perforation lines 9e, 9c, 9e using a perforation forming mold (not shown) in a predetermined second working section W2 on the ear hook sheet material 20 sent out in the conveying direction C.

[0072] Next, the eye mask manufacturing apparatus performs a bonding process (first heat-sealing process). In this process, as shown in Fig. 14, the ear loop sheet body 21 (attachment body material) is positioned behind (the side facing the face when the eye mask is worn) the strip-shaped main sheet body 11 (main body material) conveyed along the conveyance direction C. The ear loop sheet body 21 is then overlapped so that their longitudinal directions coincide and the outline 1y of each eye mask main body 1 of the main sheet body 11, which is set continuously in the longitudinal direction, coincides with the outline 9y of each attachment body 9 of the ear loop sheet body 21, which is set continuously in the longitudinal direction. The overlapped sheet body 105 is then conveyed (conveyed) along the conveyance direction C. As a result, the attachment bodies 9 of the ear loop sheet body 21 are positioned behind each eye mask main body 1 of the main sheet body 11, and the perforation line 9C is aligned in the front-to-back direction (overlapping direction) with the nose center line 1n in the vertical direction Z (conveyance direction C) located at the horizontal center of the nose pad portion 1N of each eye mask main body 1. Then, for joining the overlapping sheet bodies 105, heat-sealing lines 2S, 2S, 2T, 2T for joining the overlapping sheet bodies are formed in sequence in the conveying direction C. As a result, the sheet bodies 11, 21 (main body material, attachment material) are integrated (joined) by heat fusion, and a strip-shaped basic sheet body 106 (eye mask material) having a layered structure of integrated sheet bodies 12, 22 (main body material, attachment material) is formed, and this is conveyed out in the conveying direction C.

[0073] Furthermore, in the joining process, the main sheet body 11 (main body material) and the ear hook sheet body 21 (attachment body material) are overlapped and transported (transported out) in the transport direction C along their longitudinal direction. In this section, as shown in Figure 15, two opposing plates 81 and 82 extending in the transport direction C are stacked one above the other between the sheets 11 and 21 at a position that is the center of the sheet width direction SY, as shown in Figure 15. Of the opposing plates 81 and 82, the upper plate 81 on the ear hook sheet body 21 side is narrower than the lower plate 82 on the main sheet body 11 side, and the narrower lower plate 82 is stacked closer to the center of the sheet width direction SY than the upper plate 81. From this point on, the sheet bodies 11 and 21 are subjected to a heat fusion process to integrate them while still sandwiched between the two opposing plates 81 and 82, and are then transported to a subsequent process.

[0074] The joining heat fusion lines 2S, 2S are formed by performing dot-like or linear heat fusion along predetermined heat fusion lines 2ys, 2ys that are set to extend in the conveying direction C on both outsides of the sheet width direction SY, in a manner that intersects with the left and right outer edges of the outer heat fusion line 2D that is continuously formed along the conveying direction C on the sheet body 105.

[0075] The intended heat-sealing lines 2ys, 2ys here are set so as to extend linearly (parallel to the vertical central sections of the outline lines 1r, 1l) toward the conveying direction C inside the sheet width direction SY, relative to the vertical central sections of the left and right outline lines 1l, 1r of the outline line 1y of each eye mask body 1, which are set continuously along the conveying direction C for the sheet body 105.

[0076] The joining heat-sealing lines 2T, 2T are formed by performing point or linear heat-sealing on predetermined heat-sealing intended lines 2yt, 2yt set within the eye mask body non-forming area Q sandwiched between the outline lines 1y, 1y of adjacent eye mask bodies 1 set continuously along the conveying direction C on the sheet body 105.

[0077] The heat-sealing lines 2yt, 2yt here are formed in a cross shape on both outer sides of the sheet 105 in the sheet width direction SY, with a line extending along the conveyance direction C and a line extending in the sheet width direction SY.

[0078] In the heat-sealing process in the joining step, a cylindrical embossing die (not shown) is pressed against both outer sides of the central region SY in the sheet width direction of the sheet 105, which is sandwiched between the upper and lower opposing plates 81 and 82, in a predetermined third work section W3, and pressure and heat (heat fusion) are applied along predetermined heat-sealing lines 2ys, 2ys, 2yt, and 2yt. Here, the sheet 105 is heated by friction (e.g., ultrasonic welding, high-frequency welding, etc.) at the pressure positions applied by the embossing die. As a result, lines 2S, 2S, 2T, and 2T (here, dot-like heat-sealed lines) of hardened heat-sealed portions (hardened portions) are formed at each heated and pressed position, and the sheet bodies 11 and 21 are joined and integrated at the heat-sealed portions (2S, 2T). The integrated main sheet body 12 and ear loop sheet body 22 are overlapped so that the outline 1y of each eye mask body 1 and the outline 9y of each attachment body 9 coincide with each other, and are sent out in the conveying direction C as a strip-shaped basic sheet body 106.

[0079] The heat fusion treatment here is carried out outside the sandwiched area of ​​the sheet member 105 between the opposing plates 81 and 82 so as not to interfere with the opposing plates 81 and 82 .

[0080] Next, the eye mask manufacturing device performs a both-end cutting process (first cutting process, cutting process). In this process, as shown in Fig. 16, the strip-shaped basic sheet 106 (eye mask material) is conveyed in the conveying direction C, and both ends in the sheet width direction SY of each outline 1y (main body markings, markings) of the eye mask body 1, which are set continuously along the conveying direction C, are cut and separated in the conveying direction C (Fig. 15 → Fig. 17). Specifically, in the basic sheet 106, of the outlines 1y of each eye mask body 1 that are set continuously along the conveying direction C, the upper outline 1u of one of the adjacent outlines 1y (main body markings) faces the lower outline 1d of the other, which means that they face each other (including touching and facing each other with a gap in between), thereby connecting them in the vertical direction Z (conveying direction C), and both sheets 11 and 21 are cut (separated and cut) in a way that includes the left outline 1l and right outline 1r of each connecting outline 1y (main body markings), forming a continuous eye mask body 107. That is, the continuous eye mask body 1 forms the continuous eye mask body 107, in which the eye mask bodies 1 are connected in the vertical direction Z (C) with the eye mask body non-forming region Q in between, and is conveyed in the continuous direction (here, the same as the conveying direction C).

[0081] In the cutting process in the both end cutting step, the basic sheet body 106 sent out in the conveyance direction C is cut along predetermined cutting lines 3x, 3x by a cutting die (not shown) in a predetermined fourth work section W4.

[0082] The intended cutting lines 3x, 3x are set along the left outline 1l and right outline 1r of the outline 1y of each eye mask body 1 in the formation area of ​​each eye mask body 1, which is set continuously along the conveying direction C of the basic sheet body 106, while in the non-formation area Q of the eye mask body 1 (the eye mask body non-formation area Q interposed between adjacent eye mask bodies 1 in the conveying direction C), which is set continuously along the conveying direction C, the intended cutting lines 3x, 3x are set as lines connecting the left outline 1l and right outline 1r of the outline 1y of adjacent eye mask bodies 1 in the conveying direction C (vertical direction Z).

[0083] The cutting lines 3x, 3x here are set as curved lines that are recessed inward in the sheet width direction SY in the eye mask main body non-forming region Q, allowing a wider area of ​​the basic sheet body 106 to be cut out.

[0084] In addition, the intended cutting lines 3x, 3x here are set at least on both sides in the sheet width direction SY (towards the main body end 1S) of the intended folding lines 4x, 4x (both end positions in the sheet width direction SY of the lower plate 82) which become the folding lines 4, 4 of each eye mask main body 1 set for the basic sheet body 106.

[0085] The eye mask continuum 107 formed after the cutting process has heat-sealed portions 2s at both ends of the main body, which are provided inside the outer heat-sealed lines 2D of each eye mask body 1 among the heat-sealed lines 2S for joining, and heat-sealed portions 2t within the non-forming region, which are provided in the eye mask main body non-forming region Q among the heat-sealed lines 2T for joining, remaining.The remaining heat-sealed portions 2s, 2t maintain the integration of the main body sheet body 13 (12 → 13) and the ear-hook sheet body 23 (22 → 23) after cutting.

[0086] Next, the eye mask manufacturing apparatus performs a folding process. In this process, as shown in Fig. 23, for the main body sheet 13 (main body material) of the continuous strip-shaped eye mask web 107 conveyed along the conveying direction C, each of the concealing portions 1E, 1E (see Fig. 7) is folded along the conveying direction C at a fold line 4 (planned fold line 4x) in the vertical direction Z (here, coinciding with the conveying direction C) located in the middle (horizontal middle) of the main body sheet 13 (main body material) toward the nose pad portion 1N side (the center of the sheet width direction SY) with respect to each of the outline lines 1y (main body scribing, scribing) of the eye mask body 1, which are continuously set along the conveying direction C. At the same time, the ear loop sheet 23 (wearing body material) is folded so that both outer sides are brought toward the center while maintaining the perforation line 9C (left-right separating line) in the center of the sheet width direction SY (see Fig. 22).

[0087] The fold lines 4, 4 are arranged parallel to the perforation line 9C (the intended tear line).

[0088] By these folding operations, one or more pleats (pleats / folds f1, f2, f3) are formed in the ear loop sheet body 23 (wearing body material) of the eye mask continuum 107 along the vertical direction (conveyance direction C) symmetrically and simultaneously on both sides of the perforation line 9C (planned tear line) in areas other than the ear loop joining sections 95, 95 (heat-sealed sections / jointed sections) connecting to the blindfold sections 1E, 1E, forming expansion sections 95, 95 that can expand and contract in the front-to-back direction (the overlapping direction of the sheet bodies 13, 23) like a gusset or bellows and are connected to the corresponding blindfold sections 1E, 1E. The left and right expansion sections 95, 95 are formed entirely closer to the horizontal center than the upper and lower fused sections located at the left and right ends.

[0089] In the eye mask continuum 108 formed by these foldings, non-overlapping regions L, L where the folded ear loop sheets 24 (23 → 24) do not overlap are formed along the conveying direction C in both end regions (regions near the folding line 4) of the folded main sheet body 14 (13 → 14) in the sheet width direction SY, as shown in Fig. 22. The subsequent heat sealing and cutting processes are carried out only in the non-overlapping regions L, L, and only the main sheet body 14 is processed, not the ear loop sheet bodies 24.

[0090] In the folding process in the folding step, the eye mask continuum 107 is sent out in the conveying direction C, and the upper and lower opposing plates 81, 82, the pressing plates 83, 83, and the folding plates 84, 84 are moved in the predetermined fifth working section W5 as shown in Figures 17 to 22, thereby folding the main sheet body 13 and the ear loop sheet body 23 into different shapes.

[0091] First, the spacing means separates the central portions of the main sheet body 13 and the ear-hook sheet body 23, which are integrated and overlap each other and form the eye mask continuum 108, in the overlapping direction. Specifically, the opposing plates 81 and 82, which form the spacing means, are sandwiched (contained) between the main sheet body 13 and the ear-hook sheet body 23 at the center in the sheet width direction SY, separating them in the opposing direction (FIGS. 17, 18, and 19). Here, in section W5, the spacer 85, which also forms the spacing means, enters between the opposing opposing plates 81 and 82, which also form the spacing means, and its height gradually increases, separating the opposing plates 81 and 82. As a result, the main sheet body 13 and the ear-hook sheet body 23 are separated in the opposing direction at their respective central portions.

[0092] At the same time as this separation, the pressing means presses both end portions of the ear hook sheet body 23 in the sheet width direction SY toward the main sheet body 13. Specifically, pressing plates 83, 83 constituting the pressing means are moved toward the opposing plate 82 from both outer sides of the opposing plate 82 in the sheet width direction SY, pressing the ear hook sheet body 23 toward the main sheet body 13 (Fig. 17 → Fig. 18 → Fig. 19). Instead of the pressing plates 83, 83, rollers having an outer peripheral surface with the same width as the pressing surfaces of the pressing plates 83, 83 may be used to press the ear hook sheet body 23 toward the main sheet body 13 (pressing means). By this pressing, while maintaining the tension of the ear hook sheet body 23, in each eye mask body 1 that is set continuously along the conveying direction C relative to the main sheet body 13, the main body end parts 1S, 1S (main body folding parts: Figure 17) that are on the outer side of the folding line 4 (planned folding line 4x) in the sheet width direction SY are folded inward starting from both ends of the opposing plate 82 in the sheet width direction SY (Figure 18), and are raised toward the main body central part 1C that is on the central side of the folding line 4 (planned folding line 4x) in the sheet width direction SY (Figure 19).

[0093] Next, the folding means (folding means) pushes down the upstanding left and right body end portions 1S, 1S inward (toward the center) in the sheet width direction SY. Specifically, folding plates 84, 84 constituting the folding means are pressed inward from both outer sides in the sheet width direction SY against the upstanding left and right body end portions 1S, 1S (FIGS. 19 → 20 → 21). This pressing causes the upstanding left and right body end portions 1S, 1S to be pushed down inward starting from both ends of the opposing plates 82 in the sheet width direction SY.

[0094] At the same time as this pressing, the center portions of the main sheet body 13 and the ear hook sheet body 23 are brought closer together in the overlapping direction by the moving closer means. Specifically, the height of the spacer 85, which constitutes the moving closer means, is reduced, and the opposing plates 81 and 82, which also constitute the moving closer means, are brought closer together in the opposing direction (Fig. 19 → Fig. 20 → Fig. 21). As a result, the main body end portions 1S and 1S are pushed down while maintaining the tension of the ear hook sheet body 23.

[0095] As a result, in each eye mask body 1 set continuously along the conveying direction C, the main body sheet body 13 is folded such that the main body end portions 1S, 1S are folded inward in the sheet width direction SY and overlapped with the main body central portion 1C, and the overlapped main body end portions 1S, 1S and main body central portion 1C are sandwiched between the lower plate 82 and the folding plates 84, 84, resulting in a folded state (folded-in state).

[0096] During this process, the tension of the ear hook sheet body 23 is maintained. At each of the attachments 9 successively set along the conveyance direction C, the ear hook sheet body 23 folds back toward the main body center 1C from the joining position (2s) with the main body ends 1S, 1S as a starting point (f1), extending inward in the sheet width direction SY. Then, it folds back toward the opposite side of the main body center 1C, extending outward in the sheet width direction SY. Finally, it folds back again from both ends of the upper plate 81 in the sheet width direction SY as starting points (f3), extending inward in the sheet width direction SY. The ear hook sheet body 23, which has been repeatedly folded back in this manner, is folded toward the center of the sheet width direction SY (offset) relative to the main body sheet body 13. At this time, the ends of the ear hook sheet body 23 that join the main body ends 1S, 1S (ear hook connection portions 92, 92) are sandwiched (folded) between the main body ends 1S, 1S and the main body center 1C.

[0097] Finally, the upper and lower opposing plates 81, 82 approach each other and separate, and the folding plates 84, 84 reach a predetermined innermost position (FIG. 21) in the sheet width direction SY while maintaining tension on the ear hook sheet body 23, and separate (FIG. 20 → FIG. 21 → FIG. 22). The spacer 85 also separates. Then, a pressing means (not shown) presses the folded main sheet body 13 and ear hook sheet body 23 from the outside in the overlapping direction, forming folds at each of the folding positions f1, f2, and f3 (FIG. 21 → FIG. 22).

[0098] In this way, the eye mask continuum 107 is folded such that the main body ends 1S, 1S of each eye mask body 1 set on the main sheet body 13 are folded inward in the sheet width direction SY, and the ear loop sheet body 23 is folded with multiple folds (f1, f2, f3). The folded main sheet body 14 (13 → 14) and ear loop sheet body 24 (23 → 24) are folded such that the ear loop sheet body 24 is closer to the center of the main sheet body 13 in the sheet width direction SY, as shown in Figure 22, and become an eye mask continuum 108 with non-overlapping regions L, L formed in both end regions in the sheet width direction SY (regions near the fold line 4), and is sent out in the conveying direction C.

[0099] The folded eye mask continuum 108 has a perforation line 9C (planned tear line, left / right separation line) at the center of the sheet width direction SY of the main sheet body 13. Here, the perforation line 9C remains unchanged at the center of the main sheet body 13 in the sheet width direction SY throughout the series of folding processes.

[0100] Next, the eye mask manufacturing apparatus performs a folded corner heat-sealing process (second heat-sealing process). In this process, as shown in Fig. 24, for the folded, strip-shaped eye mask continuous web 108, the following are simultaneously formed in a line along the inside of the fold line 4: an upper fused portion 2A that heat-seals the overlapping portions (1S, 1C) of the main body sheet body 13 extending downward from the intersection of the fold line 4 and the upper outline line 1u; a lower fused portion 2B that heat-seals the overlapping portions (1S, 1C) of the main body sheet body 13 extending upward from the intersection of the fold line 4 and the lower outline line 1d; and a non-fused portion 3 that is not heat-sealed to the overlapping portions (1S, 1C) of the main body sheet body 13 located intermediate the upper fused portion 2A and the lower fused portion 2B. As a result, the overlapping main body end portions 1S, 1S and the main body central portion 1C are integrated at the upper fused portion 2A and the lower fused portion 2B to form a continuous eye mask body 109.

[0101] In addition, in the eye mask body 1 set in the folded state eye mask continuum 108, the upper fused portion 2A overlaps (1S, 1C) as an upper inclined line that approaches the nose pad portion 1N side (the center side in the sheet width direction SY) as it approaches the intersection position of the fold line 4 and the upper outline line 1u when it moves downward, and the lower fused portion 2B overlaps (1S, 1C) as an lower inclined line that approaches the nose pad portion 1N side (the center side in the sheet width direction SY) as it moves upward from the intersection position of the fold line 4 and the lower outline line 1d when it moves upward, and the overlapping (1S, 1C) are heat-sealed to each other.

[0102] During the heat-sealing process for the folded corners, a cylindrical embossing die (not shown) is pressed against the folded continuous eye mask web 108 sent out in the conveying direction C in the sixth work section W6, and heat and pressure are applied (heat fused) along a predetermined heat-sealing line 2z. The continuous eye mask web 108 is heated by friction (e.g., ultrasonic welding or high-frequency welding) at the pressure points applied by the embossing die. As a result, the folded continuous eye mask web 108 forms hardened heat-sealed lines 2A and 2B (here, inclined heat-sealed lines) at the top, bottom, left, and right corners of the folded and overlapping end portions 1S and center portion 1C of each eye mask body 1, which are arranged consecutively along the conveying direction C. The folded eye mask continuum 108 is sent out in the conveying direction C as a strip-shaped eye mask continuum 109 consisting of a main sheet body 15 (14 → 15) on which heat-sealed portions (2A, 2B) are formed and an ear loop sheet body 25 (24 → 25) folded toward the center of the sheet width direction SY relative to the main sheet body 15.

[0103] The lines 2A and 2B of the heat-sealed portions (hardened portions) here are formed as lines of linear heat-sealed portions with a small width in the sheet width direction SY, lined up at predetermined intervals, resulting in a stronger bond.

[0104] Next, the eye mask manufacturing apparatus executes a cutting process (second cutting process) near the fused portions. In this process, as shown in Fig. 25, for each outline 1y (main body crease, crease) of the eye mask body 1 that is continuously set along the conveyance direction C in the belt-shaped eye mask continuous body 109 conveyed along the conveyance direction C, only the main body sheet body 15 is cut along the outside of the upper and lower inclined lines formed by the heat-sealed portions 2A, 2B in the areas near the upper outline 1u and the lower outline 1d. This forms inclined lines 4t at the upper and lower corners of both ends in the sheet width direction of the folded main body sheet body 15.

[0105] The eye mask manufacturing apparatus also performs a separation and cutting process (second cutting process). In this process, as shown in Fig. 25, the eye mask manufacturing apparatus cuts (cuts and separates) both the main body sheet body 15 and the ear loop sheet body 25 at the upper outline line 1u and the lower outline line 1d of each of the eye mask bodies 1 that are continuously set in the conveying direction C on the eye mask continuum 109, and separates adjacent eye mask bodies 1 with the eye mask body non-forming region Q sandwiched between them in the conveying direction (C) together with the wearing body 9, by removing the eye mask body non-forming region Q.

[0106] The eye mask manufacturing apparatus then performs a nose pad forming process, in which, as shown in Fig. 25, for each outline 1y (main body marking, marking) of the eye mask body 1 that is continuously set in the conveying direction C of the eye mask continuous web 109, both the main body sheet body 15 and the ear loop sheet body 25 are cut at the center of the lower outline 1d of the adjacent eye mask body 1 in the conveying direction (C).

[0107] Here, the cutting step near the heat-sealed portion, the separating and cutting step, and the nose pad forming step are performed simultaneously as a single cutting step. Note that the cutting step near the heat-sealed portion and the separating and cutting step may be performed first and then the latter.

[0108] In the cutting process of this cutting step, the eye mask continuum 109 sent out in the conveying direction C is cut along predetermined cutting lines 5x1, 5x2, and 5x3 by a cutting die (not shown) in a predetermined seventh work section W7.

[0109] The intended cutting lines 5x1, 5x2, and 5x3 include intended upper and lower outline lines 5x1 and 5x2 that follow the upper outline 1u and lower outline 1d to separate each eye mask body 1 in the eye mask continuum 109, a nose pad shape line (included in the intended lower outline line 5x2 in this case) that cuts out the lower center of each eye mask body 1 in a predetermined shape, where the nose is located, and a heat-sealed portion vicinity line 5x3 that cuts out the outer sides of the linear heat-sealed portions 2A and 2B in the sheet width direction SY. The eye mask continuum 109 is cut along these lines 5x1, 5x2, and 5x3, and the folded eye mask bodies 1 are individually separated together with the corresponding wearing bodies 9.

[0110] In this embodiment, the upper and lower outline planned lines 5x2 (lower outline 1d) include the nose pad shape lines (cutting shape of nose pad 1N). Therefore, the separation and cutting step includes the nose pad forming step.

[0111] However, the nose pad shape line may be a cut line extending upward from the center of the lower outline 1d. In this case, the intended upper and lower outline line 5x2 (lower outline 1d) may or may not include the nose pad shape line (the cut-out shape of the nose pad portion 1N).

[0112] The heat-sealed portion vicinity line 5x3 is set so as not to remove the heat-sealed portions 2A and 2B in this cutting process. Specifically, the heat-sealed portion vicinity line 5x3 is set outside the heat-sealed portions 2A and 2B in the sheet width direction SY so as not to overlap with the heat-sealed portions 2A and 2B.

[0113] These manufacturing processes allow for the rapid mass production of folded eye masks 100. The manufactured eye masks 100 are formed symmetrically across perforation line 9C, and are efficiently manufactured by simultaneously performing various processes on both sides of perforation line 9C (presumed perforation line 9c) during the manufacturing process. Perforation line 9C is always located at the center of each sheet or each continuous eye mask body (105-109) in the sheet width direction SY during the manufacturing process.

[0114] 12 to 25 showing the manufacturing method, the sheet width direction SY coincides with the lateral direction Y (left-right direction) of the eye mask body 1, and the conveying direction C coincides with the longitudinal direction Z (up-down direction) of the eye mask body 1.

[0115] The first embodiment of the present invention has been described above, but this is merely an example, and the present invention is not limited to this. Various modifications, such as additions and omissions, can be made based on the knowledge of those skilled in the art, as long as they do not deviate from the spirit of the claims.

[0116] Below, we will explain modifications and other embodiments of the first embodiment. Note that parts that have the same functions as the above-mentioned embodiments are given the same reference numerals, and detailed explanations will be omitted. Furthermore, the above-mentioned embodiment and the following modifications and other embodiments can be combined as appropriate within the scope of not causing technical contradictions.

[0117] In the first embodiment, in each sheet or each continuous sheet (105-109) of eye masks used in the manufacturing process of the eye mask 100, the upper and lower outlines 1u and 1d of adjacent eye mask bodies 1 (lined body 1y) along the conveying direction C may be aligned in whole or in part, as shown in FIG. 26 , and no eye mask body non-forming region Q may exist between adjacent eye mask bodies 1. In this case, in adjacent eye mask bodies 1 (lined body 1y) along the conveying direction C, the upper fused portion 2A and the lower fused portion 2B formed in FIG. 24 may be connected and continuously heat-sealed, and the corresponding heat-sealed portion vicinity lines 5x3, 5x3 shown in FIG. 25 may also be connected and continuously cut. The absence of the eye mask body non-forming region Q reduces waste of material.

[0118] In the first embodiment, the eye mask 100 is joined to the wearing body 9 at the back surface 1b of the eye mask body 1, but it may be joined to the wearing body 9 at the front surface 1a of the eye mask body 1.

[0119] Furthermore, in the manufacturing method of the eye mask 100 shown in the first embodiment (see Figures 12 to 25), when each eye mask body 1 (body ruled body 1y) and each attachment body 9 (attachment ruled body 9y) which are set continuously in the conveying direction on a strip-shaped sheet are individually viewed, the eye mask body 1 is folded toward the nose pad portion 1N side (horizontal center side) at the fold lines 4, 4 in the vertical direction Z which are located in the horizontal middle part of each blindfold portion 1E, 1E, and the attachment body 9 is folded toward the center of the eye mask body 1 so as not to overlap with the end regions L, L in the horizontal direction Y of the folded eye mask body 1, forming an overlapping shape, and then the upper fused portion 2A and the lower fused portion 2B are formed, and the corresponding inclined lines 4t are formed by cutting. This method allows the upper fused portion 2A, the lower fused portion 2B, and the inclined line 4t to be formed on each eye mask body 1 that is set continuously in the conveyance direction to be efficiently formed without involving the wearing body 9, enabling high-speed mass production of eye masks 100. This method can also be applied when manufacturing eye masks 100 individually by hand, etc.

[0120] For example, it can be manufactured by the following procedure (second embodiment): Note that the same or equivalent parts as those in the manufacturing method of the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted.

[0121] First, prepare a main body material 31 and an ear loop material 41. The main body material 31 is made of a single-layer or multi-layer fabric, and is assumed to have an outline 1y of the eye mask main body 1 (a main body scribing 1y forming the eye mask main body 1). The ear loop material 41 is made of a single-layer or multi-layer fabric, and is assumed to have an outline 9y (attachment scribing) of the attachment body 9 connecting the left and right ear loop portions 91, 91 horizontally across a vertical perforation line 9C (planned tear line), a pair of planned cutting lines 9e, 9e that are contoured to form ear holes 9H, 9H in use in the left and right ear loop portions 91, 91, and a planned line 9c for the perforation line 9C.

[0122] Then, the main body material 31 and the selvedge material 41 are overlapped so that their respective score lines 1y and 9y are aligned, and the perforation line 9C and the nose center line 1n are aligned in the front-to-back direction (Fig. 27). Then, the laminated material 115, in which the main body material 31 and the selvedge material 41 are overlapped, is heat-sealed in the vertical direction Z at both ends in the horizontal direction Y to form heat-sealed joining lines 2S and 2S (Fig. 28). This forms a basic material 116 consisting of the main body material 32 and the selvedge material 42, whose both ends in the horizontal direction Y are integrated (joined) by heat fusion (2S and 2S) (joining process).

[0123] Here, the main body material 31 is made up of a multi-layered fabric and has an outer heat-sealed line 2D formed thereon, and the selvedge material 41 has perforations 9E, 9C, 9E (planned tear lines and planned cutting lines) formed thereon.

[0124] Next, the basic material 116 is cut along the outline 1y (main body crease) of each set eye mask body 1 (Figure 29: Separation Cutting Process). This forms the eye mask base body 117. This forms the eye mask base body 117, consisting of the main body base body 33 (32 → 33) and the ear loop base body 43 (42 → 43), which have been cut along the outlines 1y, 9y. The heat-sealed joining lines 2S, 2S remain on the inside of the eye mask base body 117 as heat-sealed portions 2s, 2s at both ends of the main body, maintaining the integration of the main body base body 33 and the ear loop base body 43. This cutting also forms the nose pad portion 1N.

[0125] Next, in the formed eye mask base body 117, each blindfold portion 1E, 1E (see FIG. 7 ) of the eye mask main body 1 is folded toward the nose pad portion 1N (toward the center in the horizontal direction Y) along a folding line 4 (planned folding line 4x) in the vertical direction Z (here, coinciding with the conveying direction C) located midway in the horizontal direction Y relative to the main body base body 33. At the same time, the ear loop base body 43 is folded toward the center, with both outer edges thereof moving toward the center, while maintaining the perforation line 9C (planned tear line, left-right separation line) at the center in the width direction Y ( FIG. 30 : folding process). The folding method is the same as in the first embodiment, forming folds f1, f2, and f3. These folding steps form an eye mask base body 118, with non-overlapping regions L, L formed at both ends of the folded main body base body 33 in the horizontal direction Y, where the folded ear loop base body 43 does not overlap. Here, the perforation line 9C and the fold lines 4, 4 are parallel to each other, and expansion sections 95, 95 that can expand and contract in the front-to-back direction are formed on the left and right sides of the ear hook base body 43. The expansion sections 95, 95 are provided so as to be within the mutual spacing between the fold lines 4, 4.

[0126] Next, the formed eye mask base body 118 is simultaneously formed in a line along the inside of the folding line 4: an upper fused portion 2A that heat-seals the overlapping portions (1S, 1C) of the main body base body 13 extending downward from the intersection of the folding line 4 of the folded main body base body 33 and the upper outline line 1u; a lower fused portion 2B that heat-seals the overlapping portions (1S, 1C) of the main body base body 13 extending upward from the intersection of the folding line 4 and the lower outline line 1d; and a non-fused portion 3 that is not heat-sealed to the overlapping portions (1S, 1C) of the main body base body 13 located intermediate the upper fused portion 2A and the lower fused portion 2B (Fig. 31: second heat-sealing step). These heat-sealing steps are performed along a predetermined intended heat-sealing line 2z. As a result, an eye mask base body 119 is formed in which the folded ear hook base body 43 overlaps the main body base body 34, where the overlapping main body end parts 1S, 1S and the main body central part 1C are integrated at the upper fused part 2A and the lower fused part 2B, with the folded ear hook base body 43 biased toward the center in the horizontal direction Y (in the central region excluding the end regions L, L).

[0127] Finally, the formed eye mask base body 119 is cut along the outer side of the upper and lower inclined lines formed by the heat-sealed portions 2A and 2B in the areas near the upper outline 1u and the lower outline 1d, forming inclined lines 4t (FIG. 32: cutting process near the fused portions, second cutting process). The cuts are made along predetermined lines 5x3 near the heat-sealed portions. This completes the eye mask 100 similar to the first embodiment.

[0128] In the second embodiment, the main body material and the ear loop material may be cut along the outline of the eye mask 1, and then the subsequent steps may be performed with them referred to as the main body and the attachment body. Cutting along the outline of the eye mask 1 may be performed before the main body material and the ear loop material are integrated (joined). [Explanation of symbols]
