Description

Technical Field

[0001] This invention relates to the field of eye mask technology, and in particular to an eye mask body, a sleep eye mask, and a method for manufacturing the same. Background Technology

[0002] An eye mask is a tool used to cover the eyes and block out light, especially when used during the day and outdoors. Eye masks can eliminate light interference and create a suitable environment for sleep. They are widely used in sleep aids, medical rehabilitation, and travel protection. With the development of eye mask technology, how to improve the wearing comfort of eye masks has become an urgent problem to be solved.

[0003] The structure of an eye mask usually includes the eye mask body and ear loops. In order to improve wearing comfort, existing technologies have improved the material of the eye mask body to increase the softness of contact with the face, and made the ear loops of elastic material to adapt to different face shapes so that the mask body fits the face better. However, when the eye mask fits the face too closely, it will cause pressure on the eyeballs, and wearing it for a long time will cause discomfort.

[0004] In existing technologies, to alleviate pressure on the eyeball, concave structures are often used in the eye area to reduce contact with the eye; for example... Figure 1 and Figure 2 As shown, US Patent No. US20140331383A1, published on November 13, 2014, discloses a sleep mask. This mask features a recessed support structure 01 on its fabric structure that adapts to the wearer's eye socket area. It also includes a first filling layer 02 and a second filling layer 03, which have a loose structure for ventilation and moisture evaporation. The recessed support structure reduces pressure on the eyeballs. Figure 3 and Figure 4 As shown, U.S. Patent No. US20230062643A1, published on March 2, 2023, discloses an eye mask, headband, and sleep eye mask. The headband 04 is provided with two eye mask covers 05, each covering one eye. The eye mask covers 01 are also provided with a C-shaped breathable pad 06 and a light-blocking pad 07. In this way, the recessed part of the eye mask cover 01 corresponds to the eyeball, so there is no pressure when wearing it, which improves the comfort of wearing it.

[0005] However, the above-mentioned eye mask manufacturing process is relatively complex and the processing cost is high. It also requires high precision when wearing it. If it is not aligned with the eyeballs or if the eye mask shifts when turning over, the recessed support edge is more likely to compress the eyeballs and cause discomfort. Summary of the Invention

Detailed Implementation

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0039] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0041] like Figures 5 to 6 The illustrated eye mask body includes a fabric structure 1, which is configured to cover the user's eye area. It should be explained that, in embodiments of the present invention, as... Figure 7 As shown, the eye area refers to the area of ​​the user's face from above the nose to below the brow bone, and the eyeball area refers to the area between the user's eye sockets. In embodiments of the present invention, the material of the fabric structure 1 can be various, such as natural fiber materials, soft, skin-friendly and breathable cotton, smooth and delicate silk with low friction, etc.; it can also be synthetic fiber materials, such as polyester, cellulose fiber, polycarbonate; in addition, it can be some functional materials, such as non-woven fabric, graphene, etc., or it can be a mixture of space cotton, spandex, etc.

[0042] In embodiments of the present invention, such as Figure 5 and Figure 6 As shown, the fabric structure 1 has a long, narrow groove 11 in the middle. The long, narrow groove 11 is recessed towards the side facing away from the contact surface of the fabric structure 1. When the fabric structure 1 is unfolded, the long, narrow groove 11 forms a continuous 3D recessed space facing away from the contact surface. This 3D recessed space at least covers the wearer's eye area, and the 3D recessed space opens towards the wearer's face. It should be noted that, in the embodiments of the present invention, the fabric structure 1 is generally a long rectangular structure, with the middle part referring to the middle position in the width direction. Generally, when wearing an eye mask, the user's eyes are located in the middle position of the eye mask, so the long, narrow groove 11 is positioned just enough to cover the eye area. In some specific embodiments of the present invention, the length of the fabric structure 1 is 195-210 mm, and the width is 75-85 mm; the width of the long, narrow groove 11 is 30-40 mm, and it is centrally located in the width direction. In the embodiments of the present invention, the length of the long, narrow groove 11 can be as follows: Figure 5 and Figure 6 The single groove shown extends from the left to the right; of course, those skilled in the art can also construct two symmetrical elongated grooves 11 on the fabric structure 1 by folding, thus forming two symmetrical elongated grooves. The width of the elongated grooves remains unchanged, and the length is set to be no less than the width of the eye socket. The 3D recessed space here is as follows: Figure 6 As shown, when the fabric structure 1 is unfolded and worn, the elongated groove 11 can be manually opened. In the embodiments of the present invention, the depth of the elongated groove 11 before unfolding is less than 7mm, and the depth after unfolding can reach about 8-15mm. With this setting, the area directly facing the eyeball after the user wears the eye mask presents a 3D recessed space, thereby avoiding pressure on the eyeball from the eye mask. Even if the eye mask shifts to a certain extent when the user turns over or turns their head, as long as the eyeball is still within the 3D recessed space, the shift will not cause pressure on the user's eyes like the grooves set directly facing the eyeball in the prior art, thereby improving the user's wearing comfort. In addition, it should be noted that in the embodiments of the present invention, the elongated groove 11 can be formed by bending and layering the fabric. There are various specific processes, such as hot pressing, molding, or folding and shaping, sewing and pleating. Some specific processes of the present invention will be illustrated in the following embodiments. The 3D recessed space here refers to the elongated groove that, after being stretched and worn, creates a recessed space, such as... Figure 6 and Figure 8 As shown, its surface forms a non-planar or curved structure. It should also be noted that, in the embodiments of the present invention, the elongated groove 11, when not stretched, fits snugly against the fabric structure 1. This structural form also improves the convenience of product packaging and placement, occupies little space, and is easy to open. The 3D recessed space here, opening towards the wearer's face, refers to... Figure 9 and Figure 10 As shown, the opening of the elongated groove 11 faces the wearer's eye area, so that the protruding part of the eyeball can be placed inside the elongated groove 11, that is, the opening of the elongated groove 11 faces the wearer's face.

[0043] In the above embodiments, the elongated groove 11 formed on the fabric structure 1 creates a 3D recessed space covering the eyeball area when the fabric structure 1 is unfolded. This structural form can be achieved simply by bending, resulting in a simple structure and low manufacturing cost. Furthermore, the elongated 3D recessed space reduces the precision requirements for the user's wearing experience. Even if the eye mask shifts to some extent during use, it will not affect wearing comfort. Compared with existing technologies, it not only has a simple structure and low cost but also improves wearing comfort. In addition, the 3D recessed space in this embodiment is only unfolded when in use and can be folded when not in use, for example, by being stored folded during production. This reduces the space occupied by the eye mask body, making it easier to carry and transport.

[0044] Based on the above embodiments, the specific structure of the elongated groove 11 is as follows: Figure 9 As shown, the elongated groove 11 includes a cavity bottom 111 and connecting walls 112 connected to both sides of the cavity bottom 111 in the width direction. The other ends of the two connecting walls 112 are respectively connected to the fabric structure 1. It should be noted here that the cavity bottom 111 refers to the bottom part of the elongated groove formed by the elongated groove 11, that is, as shown in the figure. Figure 5 , Figure 6 , Figure 8 The raised surface portion shown, and the connecting wall 112 refer to the bent portion, such as... Figure 9 As shown, the bending of the connecting wall 112 creates a certain distance between the cavity bottom 111 and the fabric structure 1. This distance constitutes the depth of the elongated groove when it is not unfolded. The bending of the connecting wall 112 allows the depth of the elongated groove to change; that is, after the connecting wall 112 is unfolded, as shown... Figure 10 As shown, this further deepens the elongated groove. In embodiments of the present invention, the fabric structure 1 and the elongated groove 11 use the same piece of fabric. Only the connecting wall 112 needs to be folded or compressed and stretched to form a 3D recessed space when the fabric structure 1 is opened. The structure is simple and easy to implement. In addition, in some embodiments of the present invention, besides the elongated groove 11 being integrally formed on the fabric structure, the cavity bottom 111, the connecting wall 112, and the fabric structure 1 can also be formed by splicing. For example, the two sides of the cavity bottom 111 are spliced ​​to two connecting walls 112 respectively, and the other ends of the two connecting walls 112 are spliced ​​to the fabric structure 1 respectively.

[0045] Optionally, such as Figure 11As shown in the embodiment of the present invention, the elongated groove 11 extends from one end of the fabric structure 1 along its length to the other end, and both ends of the elongated groove 11 are fixed to the edges of the fabric structure 1. That is, the length of the elongated groove 11 is close to the length of the eye mask, so that when forming the elongated groove 11, it is only necessary to fold the fabric at both ends to form the shape shown. Figure 11 The elongated groove 11 shown from left to right can provide a maximum 3D recessed space and simplify the processing procedure.

[0046] Specifically, in some embodiments of the present invention, such as Figure 11 and Figure 12 As shown, the fabric structure 1 has compression portions 12 at both ends along its length. The compression portions 12 are used to compress the overlapping portions of the fabric structure 1, the cavity bottom 111, and the connecting wall 112 into a single unit. The compression portions 12 can be formed in various ways, such as by hot pressing, ultrasonic vibration bonding, molding, or sewing. By compressing the overlapping portions of the connecting portion, the cavity bottom 111, and the fabric structure 1, the structural strength on both sides of the fabric structure 1 can be strengthened. Furthermore, the compression at both ends causes the elongated groove to naturally expand near the compression portions 12, forming a groove of a certain depth, which also facilitates the unfolding and forming of the elongated groove 11.

[0047] Please continue to refer to Figure 12 In some embodiments of the present invention, the compression portion 12 intrudes inward toward the two connecting walls 112, forming a W-shaped structure. Here, "W-shaped" refers to the compression portion 12 extending away from the edges near both ends, causing the elongated groove 11 to form arcs at both ends. This structural arrangement increases the length of the eye mask around the eyeballs, and the intruded portion is also used for connection to the ear loops, as will be described in detail in the following embodiments of the present invention.

[0048] Optionally, such as Figure 11 and Figure 13 As shown, to further improve the comfort of wearing the eye mask, the elongated groove 11 has a compression mark 13 arranged along the width direction at the middle position of its length direction. The compression mark 13 forms two symmetrical cavities in the elongated groove 11. The compression mark is set in the width direction, which can compress the entire elongated groove 11 in the middle part. That is, at the middle position of the length direction, the connecting wall 112 is compressed to a certain extent, so that the height of its two sides is higher than that of the middle part. This structure can provide a certain degree of movement space for the eyes even when the eye mask is not unfolded, reducing discomfort when wearing it.

[0049] In some embodiments of the present invention, the fabric structure 1 has a multi-layer structure, and the fabric structure has radial indentations 14 at the edges, and the multi-layer structure is connected at the edges through the radial indentations 14. Specific connection methods can include hot pressing, ultrasonic pressing, or adhesive bonding, etc. The multi-layer structure can be two, three, or four layers, etc. Specifically, as shown... Figure 14 As shown, the fabric structure 1 includes a light-blocking layer 110 and a filling layer 120. The light-blocking layer 110 may only provide light blocking on the outer layer, or it may be as follows: Figure 14 The light-blocking layer 110, shown in the diagram, provides light protection on both the inner and outer sides. It can be a dark color such as black, dark blue, or dark brown. The material can be non-woven fabric. The filling layer 120 is generally located in the middle and can be a sponge or hot-air cotton structure to increase wearing comfort. In embodiments of the invention, during cutting, the multi-layered structure is prone to cracking at the edges when the cutter falls, requiring high precision from the cutter. Figure 11 As shown, the radial indentations 14 evenly distributed along the edges allow the fabric structure to bond together at the edges, preventing unevenness during cutting; furthermore, the length of the radial indentations 14 is... Figure 11 The material is twice the size shown, with the other half on the waste material. The radial indentation 14 also provides leeway for the cutting position of the cutter, ensuring that even slight displacement of the cutter during cutting does not affect the product yield. Furthermore, in embodiments of the present invention, please refer to [reference needed] for the specific location of the filler layer 120. Figures 22 to 24 ,like Figure 22 As shown, the filler layer 120 can be sandwiched throughout the intermediate layer, or it can be used as... Figure 23 As shown, the filling layer 120 fills the cavity bottom 111 and the connecting wall 112, or it can also be as shown in the figure. Figure 24 The structure shown has a 120-pound filling layer at the bottom of the cavity 111. This structure improves the stiffness of the fabric eye mask in the recessed space. For example, when using silk floss, the recessed space is prone to collapse. The filling layer at the bottom of the cavity 111 keeps the recessed space raised, improving wearing comfort.

[0050] In embodiments of the present invention, the eye mask body can be a disposable eye mask or a fabric eye mask; when making a disposable eye mask, non-woven fabric is often used as the main material. The fabric structure 1 is integrally formed by pressing, specifically by hot pressing or ultrasonic pressing. Integral forming here means that the aforementioned elongated groove 11 and the multi-layered fabric structure 1 are pressed together from a single sheet of fabric. This pressing connects the multiple layers of fabric at the edges and also forms the elongated groove 11. Specifically, when pressing the elongated groove 11, as follows... Figure 15As shown, multiple folded structures 112a are pressed onto the connecting wall 112. It should be noted that the folded structures 112a can take various forms, such as serpentine folds or fan-shaped folds. A fan-shaped fold refers to a fold where two layers fit tightly together during compression, similar to a fan. A serpentine fold, on the other hand, has a certain gap between adjacent layers, such as... Figure 15 As shown; furthermore, to further improve support after deployment, such as Figure 16 As shown, the folded structure 112a has creases formed by a hot-pressing process, which support the 3D recessed space after unfolding. See reference for details. Figure 6 Since the crease extends along the length direction, when it is unfolded, it can form a vertical groove on the connecting wall 112. This vertical groove supports the crease and prevents the crease from returning to its original position, thereby allowing the 3D recessed space to maintain its shape.

[0051] In embodiments of the present invention, when the eye mask is not disposable, natural materials such as cotton, silk, and linen are generally selected, and synthetic fiber materials such as polyester fiber and spandex can also be used, or functional materials such as memory foam and bamboo fiber can be used. In specific processing, the fabric structure 1 is integrally formed by sewing. Specifically, as follows... Figure 8 and Figure 13 As shown, the connecting wall 112 is formed into continuous pleats through sewing. Here, the pleats refer to the bent portions formed at the bends of the connecting wall 112, extending along the length of the eye mask. In specific sewing operations, the fabric can be folded first, and then the two ends of the fabric can be sewn together, so that the bends at both ends of the connecting wall 112 are flattened by the seam. Furthermore, in embodiments of the present invention, wavy stitching or zigzag stitching can also be used to form the pleats. Please continue to refer to... Figure 9 or Figure 15 The pleats are Z-shaped or wavy. This structure is similar to that of the disposable eye mask mentioned above, except that the disposable eye mask can form creases at the bends, while the creases of the fabric eye mask are flexible. To further deepen the pleats, a post-setting process can be used, such as steam ironing at 120 degrees Celsius, with a pressure of 0.2 MPa for 10 seconds; or it can be achieved by hot pressing, with a mold temperature of 150 degrees Celsius, a pressure of 0.5 MPa, and a holding time of about 15 seconds.

[0052] In an embodiment of the present invention, a sleep mask is also provided, such as... Figure 17As shown, the mask includes any of the aforementioned features and ear straps 200 connected to both ends of the mask body. It should be noted that the ear straps 200 can take various forms; one end connects to the mask body, and the other end is for the user to wear. Generally, they can be hung on the ears, or they can be worn directly over the head. The following is an illustrative description of the structure of the ear straps 200. In one exemplary structure of the present invention, the ear straps 200 can be made of TPE or silicone elastic bands; or they can be made as adjustable straps, adjustable via D-rings or snaps, and can be worn over the head; in some embodiments of the present invention, magnetic hook-and-loop ear straps 200, quick-release buckle ear straps 200, or Velcro fastening can also be used, etc. Please continue to refer to... Figure 17 In an embodiment of the present invention, in order to improve the reliability of the connection between the ear strap 200 and the eye mask body, the connection point between the eye mask body and the ear strap 200 is located on both sides in the width direction of the elongated groove 11, that is, the connection point of the ear strap 200 is near the connection wall 112 of the elongated groove 11. As can be seen from the description in the above embodiment, the elongated groove 11 overlaps at both ends of the fabric structure 1, so the structural strength at this point is relatively large, and as... Figure 11 and Figure 12 As shown, by providing the compression part 12, when the ear strap 200 is worn after being connected to the compression part 12, the tension of the ear strap 200 can extend along the length direction of the connecting wall 112, and the tension is distributed on the upper and lower sides of the eyes. With this structure, the tension can be distributed on the connecting wall 112, which can reduce the pressure on the eyes on the one hand, and the tension provided on the connecting wall 112 can also achieve the shape preservation effect of the 3D concave space.

[0053] Optionally, in some embodiments of the present invention, the wearing length of the ear loop 200 is adjustable to accommodate the wearing needs of different groups of people. There are various specific methods for length adjustment; please refer to further details in some embodiments of the present invention. Figure 17 The ear loop 200 is an elastic cord. The elastic cord can be made of various materials, such as rubber, which is elastic and inexpensive; or thermoplastic elastomers, which are highly flexible; in some embodiments of the invention, the elastic cord can be made of silicone or polyurethane; furthermore, composite materials such as natural rubber and TPE can be used. In addition, in some embodiments of the invention, the length of the ear loop 200 can be adjusted using a structure of elastic cord and spring buckle, such as... Figure 17As shown, the spring buckle is a push-to-unlock mechanism. It passes through the end of the elastic cord. When adjusting, pressing the protrusion of the spring buckle adjusts its position on the elastic cord, thereby changing the ear loop bearing of the ear strap 200. After pressing the protrusion of the spring buckle, the ear strap 200 is stretched or contracted to the desired length. Releasing the spring buckle will automatically lock the ear strap. This adjustment method is convenient, reliable, and stepless, making it more adaptable.

[0054] Optionally, in another embodiment of the present invention, a sheet-like adjustable ear loop 200 is also provided, specifically as follows: Figure 18 and Figure 19 As shown, the ear loop 200 is a sheet-like structure that fits onto one side of the contact surface of the eye mask body. The ear loop 200 has a pre-cut line 202 in the middle, and multiple ear hole contour tangents are symmetrically arranged on the ear loop 200 from the inside to the outside. In embodiments of the present invention, the sheet-like ear loop 200 can be made of spunbond nonwoven fabric, which is formed by hot pressing polypropylene or polyester fibers, and has the advantages of being soft, breathable and comfortable to wear; it can also be made of meltblown nonwoven fabric, which is formed by high-speed hot air stretching of ultra-fine fibers with a diameter of 1-4 micrometers, and has fine fibers and a soft feel; it can also be made of spunlace nonwoven fabric, which is formed by high-pressure water jet weaving of fibers and has a hydrophilic surface treatment, and has high strength; in addition, composite membrane materials can also be used, such as nonwoven fabric combined with PE film or TPU film. The pre-cut line 202 in the middle is used to divide the ear loop 200 in two. In actual manufacturing, the pre-cut line 202 is either a non-cut, easily tearable pre-cut form or a form that retains only a few connection points. This structural design allows the sheet-like ear loop 200 to adhere to the contact surface of the goggle body 100 in its initial state, reducing the overall volume and facilitating carrying and packaging, making it particularly suitable for disposable goggles. Please continue to refer to... Figure 18 and Figure 19 The ear canal outline has a hole structure similar to the cross-sectional structure of the ear at the midpoint on both sides of the pre-cut line 202. This allows the ear loop 200 to be torn into two pieces and then fitted onto the left and right ears respectively. Due to its material properties, it has a certain degree of elasticity and stretchability. For further improvement in adaptability, please refer to [the relevant documentation]. Figure 18 The ear canal also includes an arc-shaped tangent and radial slits facing the tangent in the outward direction. This structural design allows for the formation of a larger area connecting the ear canal with the slits and arc-shaped tangent when the ear canal cannot be used, thus accommodating larger or farther-set ears.

[0055] In some embodiments of the present invention, a sleep mask is also provided, such as... Figure 20 As shown in the illustration, the sleep mask in this embodiment of the invention is suitable for a press-molded eye mask, specifically including an eye mask body 100 and ear straps 200, such as... Figure 20 As shown, the eye mask body 100 has at least two spaced creases 101 in the middle, extending along the length direction. It should be noted that in embodiments of the invention, the creases 101 are formed by folding and pressing the fabric; there can be two creases or multiple creases. An elongated groove 102 is formed between the two outermost creases 101, which, when the eye mask body 100 is unfolded, forms a cavity covering the eye area. Figure 20 As shown in the embodiments of the present invention, the ear loops 200 are connected to both sides of the eye mask body 100. In some specific embodiments of the present invention, the eye mask body 100 is made of three layers of SMS nonwoven fabric, which is a dark-colored light-blocking eye mask. The three layers are a spunbond layer, a meltblown layer, and a spunbond layer, with a length of 200 mm and a width of 80 mm. The ear loops 200 are made of TPE elastic cords, and the two ends of each ear loop 200 are connected to both sides of the eye mask body 100 along its length. Regarding the specific structure of the crease 101, the crease 101 is a Z-shaped fold in cross-section. The elongated groove 102 is formed between two symmetrical Z-shaped creases 101. The Z-shaped crease 101 is first folded outward from the mask body, and then folded inward once according to a set depth. Then it is formed by hot pressing. In the embodiments of the present invention, the edges of the eye mask body 100 are also held together by hot pressing to achieve the adhesion of multiple layers of fabric. Furthermore, in an embodiment of the present invention, a nose recess is provided in the middle part of the eye mask body 100 for wearing comfort; in an embodiment of the present invention, in addition to the above-mentioned elastic rope structure, the sleep eye mask can also adopt the sheet structure mentioned above. The specific structure has been described in detail above and will not be repeated here.

[0056] Optionally, in embodiments of the present invention, to improve the reliability of the ear loop 200 connection and further enhance wearing comfort, the creases 101 overlap and press at the edge of the eye mask body 100, and the ear loop 200 is connected to the overlapping points of the two outermost creases 101. In specific connection, the ear loop 200 can be sandwiched in the gaps of the creases 101, and then pressed together with the eye mask body 100. With this structure, the tension of the ear loop 200 is transmitted to the creases 101 during wear. On the one hand, this maintains the creases 101 as recessed spaces; on the other hand, it transmits the force to the fabric where the creases 101 are located, thereby dispersing the force on the eye mask body 100. Furthermore, since the elongated groove 102 can cover both eyes, the tension of the ear loop 200 is distributed on the upper and lower sides of the eyes. This structural form not only improves structural strength but also reduces pressure on the eyes. In addition, in some embodiments of the present invention, such as... Figure 20As shown, small indentations can also be formed by dot-like pressing at the upper part of the nose concave, that is, at the middle position in the length direction of the eye mask body 100. The depth and distribution of these indentations will cause the elongated groove 102 on the fabric to form two cavities on the left and right sides, which allow the eyes to have enough room to move.

[0057] In embodiments of the present invention, a method for manufacturing a sleep mask is also provided. This method can be used to manufacture disposable sleep masks as well as fabric sleep masks. Specifically, as follows... Figure 21 As shown, it includes the following steps: S10: Folding and stacking the multiple layers of fabric according to the dimensions of the elongated groove 102; the eye mask in this embodiment of the invention differs from the traditional flat design eye mask in that it adopts a design that allows the fabric to be folded and stacked. The dimensions of the elongated groove 102 specifically refer to the depth and width of the groove. In this embodiment of the invention, the width of the elongated groove 102 is not less than the vertical distance between the eyes, so that the elongated groove 102 can cover the eyes when unfolded, avoiding pressure on the eyes; the depth of the elongated groove 102 is about 5-12mm; S20: Press crease 101, press the eye mask body 100 to form crease 101; please refer to the following for details. Figure 22 This refers to the structural shape of the eye mask body 100 after pressing and molding. It should be noted that before folding and stacking the fabric, it can be cut according to the unfolded shape, or it can be cut after pressing the creases 101, or the edges can be trimmed after step S30. The specific pressing method can be hot pressing or molding, etc.

[0058] S30: Press the edge. Press the edge of the eye mask body 100 to keep the multiple layers of fabric together. It should be noted that the edge pressing can be achieved by dot pressing or strip pressing, or both. For example, dot pressing can be used to position the edges around the perimeter, and then strip pressing can be used inside the dot pressing to fix the layers together. It should also be noted that in the embodiments of the present invention, the pressing of the crease 101 and the edge pressing in step S30 can be performed sequentially, or they can be formed by a composite mold in one stamping.

[0059] S40: Trimming, removing excess parts from the edge of the eye mask body 100; In embodiments of the present invention, this trimming may be done after pressing the edge, trimming the burrs on the edge to make it fit the face better; or it may be trimming the edge of the whole after pressing in one go.

[0060] S50: Connects the ear strap 200, which is connected to the eye mask body 100 by pressing; see details for reference. Figure 18 In embodiments of the present invention, local hot-press bonding is performed in the form of small square dots, which can be either hot-press bonding or ultrasonic vibration bonding. S60: Cover the ear loops 200, forming a W-shaped structure at the connection between the ear loops 200 and the eye mask body 100; this step is to further improve the reliability of the ear loop connection, such as... Figure 18 and Figure 12 As shown, this structural design increases the length of the eye mask body 100 around the eyeball. In this embodiment of the invention, the two V-shaped inflection points of the W-shape are located at the folded position. This structural design ensures that the stress points of the entire eye mask body 100 are on the upper and lower sides of the eyeball after wearing, thus avoiding stress on the eyeball, reducing the pressure during wear, and improving wearing comfort.

[0061] S70: Center pressing. Pressing is performed in the center of the eye mask body 100 to create two cavities on the left and right sides of the elongated groove 102. It should be noted that during the pressing process, a dotted pressing method can be used to create a pattern on the fabric of the eye mask body 100. Figure 11 , Figure 13 or Figure 17 The indentation shown can be a single line, or two or more lines arranged side by side. Through the setting of the middle indentation and the two sides covering the ear strap 200 area, the elongated groove 102 forms two symmetrical cavities on the left and right sides. These cavities also provide space for the eyes to move, and provide more sufficient space for the eyes to move after the eye mask is unfolded.

[0062] In an embodiment of the present invention, a sleep mask is also provided, which is mainly made using a sewing process, such as... Figure 23As shown, the sleep mask also includes a mask body 100 and ear straps 200 connected to both ends of the mask body 100. The eye mask body 100 has at least two spaced pleats 103 in the middle, which extend along the length direction. The two outermost pleats 103 form an elongated groove 102. After the eye mask body 100 is unfolded, the groove can form a cavity covering the eye area. It should be noted that in the embodiments of the present invention, the pleats 103 are achieved by sewing. There are various ways to achieve this. For example, it can be done by folding the eye mask body 100 first and then sewing the two ends together, thus forming the pleats 103. In addition, in the embodiments of the present invention, since the fabric eye mask has a certain thickness, the pleats 103 can also be formed by straight sewing the eye mask body 100 along the length direction, so that the thickness of the sewn area is reduced, thereby forming the elongated groove 102. The ear straps 200 are connected to the two sides of the eye mask body 100. The connection here is also achieved using a sewing process. The ear loops 200 can take various forms, such as elastic bands or the aforementioned spring-loaded buckles, to achieve stepless length adjustment. Those skilled in the art can choose according to their needs. Furthermore, it should be noted that due to the sewing process, the length of the pleats 103 can be varied. It only needs to be longer than the length of the eye, and have some redundancy in the length of the pleats 103 when the eye mask body 100 shifts slightly, to prevent the portion outside the elongated groove 102 from pressing on the eyes. If only one elongated groove 102 is provided, its length should not be less than 100mm. If two elongated grooves 102 corresponding to the eyeballs are provided, their lengths should range from 30-50mm, with a center distance of 55-75mm. The aforementioned structural forms of the elongated grooves 102 still fall within the protection scope of this invention.

[0063] Optionally, in some embodiments of the present invention, the pleats 103 overlap and are sewn together at both ends of the eye mask body 100 along its length, and the ear straps 200 are connected to the overlapping portions of the two outermost pleats 101. Specifically, during the connection, the ear straps 200 can be held in the overlapping layers of the pleats 103, and then the overlapping portions of the ear straps 200 and the pleats 103 are sewn together with the eye mask body 100. This structural design improves the mechanical properties of both the eye mask body 100 and the ear straps 200, for example, increasing the tensile strength of the overlapping area and the tensile strength of the ear strap connection points. Furthermore, the above-mentioned structural design can improve wearing comfort. By connecting with the stitched area of ​​the pleats 103, the pressure of the stitched area can be distributed to avoid localized compression. The connection with the ear straps 200 can achieve a flexible transition, preventing the ear straps 200 from directly contacting the face. In addition, the above structural improvements can improve the structural stability of the eye mask body and also ensure that the groove depth at the pleats 103 structure can be well maintained.

[0064] In an embodiment of the present invention, a method for manufacturing a sleep mask prepared by the above-described sewing process is also provided. In this embodiment, the focus is still on the pleated form 103 achieved through folding, specifically as follows: Figure 24 As shown, the steps include: S100: Fold and stack multiple layers of fabric according to the dimensions of the elongated groove 102. Before folding, the width of the fabric can be cut to be slightly larger than the width of the eye mask body 100, forming a continuous elongated shape, which allows for continuous sewing and improves production efficiency. The elongated groove 102 is achieved by folding. Specifically, each fold 103 can be folded two or more times. After stacking, the fabric can be shaped by single-needle sewing, ironing, or high-temperature steaming.

[0065] S200: The main body 100 of the eye mask is sewn to form pleats 103. In an embodiment of the present invention, taking the pleats 103 as extending from one end to the other along the length of the main body 100 of the eye mask as an example, when sewing, only the two ends need to be sewn to form pleats 103. The two pleats 103 form an elongated groove 102. It should also be noted that in an embodiment of the present invention, vertical sewing can also be performed in the middle of the elongated groove to form two symmetrical grooves. This arrangement can improve the fit with the face. Of course, when vertically sewing in the middle, sewing can also be performed on both sides of the bridge of the nose. This can improve the fit between the mask and the human face and reduce displacement when the user turns over or turns their head. In addition, the middle sewing arrangement can also form two symmetrical cavities, providing space for the eyes to move when wearing the mask.

[0066] S300: Sew the edges of the eye mask body 100 together to keep the multiple layers of fabric together; the edge sewing is to sew a complete circle around the edge of the eye mask body 100, and there are various sewing techniques used, such as four-sided overlock sewing, flat sewing, double-needle chain sewing or coverstitch sewing.

[0067] S400: Trim the edge of the eye mask body 100 and perform edge binding; In the sewing process, there are many ways to bind the edges, such as using overlock stitch, binding stitch, folded stitch or double needle binding.

[0068] S500: The ear loop 200 is connected by sewing. Similar to the above embodiment, in this embodiment of the invention, when connecting the ear loop 200, the ear loop 200 can be embedded into the pleat 103 and sewn together. This method can improve the strength and reliability of the ear loop 200 connection. Furthermore, during sewing, a small area can be sewn at the connection between the pleat 103 and the ear loop 200 to form the aforementioned W-shaped structure, thereby further improving structural strength, enhancing wearing comfort, and providing a certain degree of support after the elongated groove 102 is unfolded.

[0069] Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
