Description

Technical Field

[0001] This utility model relates to the field of hygiene products, specifically to a fluffy and comfortable waistband and hygiene products. Background Technology

[0002] Hygiene products include diapers, pull-up pants, and overnight pants. These hygiene products consist of the pants body and the waistband on the pants body. The waistband has a certain degree of elasticity, so when the hygiene products are worn, the waistband fits snugly against the waist under the action of elasticity, thereby preventing the hygiene products from falling off.

[0003] Infants, as the primary user group of hygiene products, differ from adults in that their delicate skin makes them susceptible to marks and indentations from waistbands, affecting the comfort of using hygiene products. Furthermore, waistband comfort is currently an important factor in hygiene product purchasing decisions, with consumers increasingly focusing on its comfort level. Therefore, minimizing waistband marks and indentations and improving overall comfort is crucial. Chinese patent application CN117618191A discloses a flexible waistband and sanitary products, and Chinese patent announcement CN221600431U discloses a waistband and sanitary products. Both of these existing patents were previously filed by the applicants. The existing technology limits the parameters of the folds (such as fold density, width, and crest) and the parameters of the elastic elements (such as the number of elastic elements, denier, spacing between adjacent elastic elements, elastic elongation, and elastic recovery rate), thereby making the folds formed on the waistband surface smaller and the folds denser, thus improving the smoothness of the waistband surface. When worn, it is more delicate and feels better against the skin, and will not leave large or obvious marks on the waist, greatly reducing the occurrence of marks and making it more comfortable to wear.

[0004] Although infants are the primary users of sanitary products, and the aforementioned waistband improvements enhance infant comfort and resolve technical issues, the buyers of sanitary products are not infants, but rather their parents. Parents do not experience the comfort of sanitary products through actual use; they primarily judge comfort based on appearance. Therefore, the appearance of sanitary products and their visual impact on parents directly affect sales. While the aforementioned waistband improvements can enhance infant comfort, the surface of these existing waistbands features multiple tightly packed pleats. These closely arranged pleats create a sense of tightness and pressure, potentially leading parents to mistakenly perceive the waistband as causing significant pressure and discomfort for the infant's lower back. Utility Model Content

[0005] The present invention aims to provide a fluffy and comfortable waistband and hygiene product, so that the waistband has a more fluffy appearance, giving buyers a certain visual impact, solving the problem that buyers may mistakenly believe that the waistband puts too much pressure on the baby's waist and is not comfortable, thus giving buyers a better visual impression and increasing product sales.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fluffy and comfortable waistband, comprising an elastic layer and a surface layer; the outer side of the waistband is divided into an outer fluffy section and an outer pleated section, the outer fluffy section being located above the outer pleated section; the surface layer of the outer pleated section is fixedly attached to the elastic layer, and there is a gap between the surface layer of the outer fluffy section and the elastic layer.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: hygiene products, including trousers and a fluffy, comfortable waistband located on the trousers.

[0008] The principle and advantages of this application are as follows: This application mainly improves the waistband of sanitary products. The outer side of the waistband (the side away from the skin when worn) is divided into an outer loose section and an outer wrinkled section. The outer wrinkled section is the part where the surface of the outer wrinkled section is fixedly attached to the elastic layer. The surface of the outer wrinkled section has multiple tight wrinkles, which are formed by the waistband shrinking under the action of elasticity. As for the outer fluffy section, there is a gap between the surface layer and the elastic layer. This means the surface layer of the outer fluffy section is not fixed to the elastic layer, and the elasticity of the elastic layer does not act on the surface layer of the outer fluffy section. Therefore, the surface layer of the outer fluffy section does not form tight wrinkles with the contraction of the elastic layer. Thus, the surface of the outer fluffy section only has loose wrinkles, giving a relaxed visual impression rather than a tight, contracted one. The outer fluffy section appears more voluminous (the surface layer of the outer fluffy section floats on the surface, resembling bubbles). This solves the problem of buyers visually perceiving that the waistband puts too much pressure on the baby's waist and is uncomfortable, giving buyers a better visual impression. Consumers will be more inclined to favor hygiene products containing this waistband, which is beneficial for increasing product sales.

[0009] In this design, the outer puffy section is located on the outer side of the waistband, rather than on the inner side (the side of the waistband that touches the skin). This makes the outer puffy section more visible to the buyer, giving them a different visual experience.

[0010] Because the waistline tapers from bottom to top (the diameter of the waistline gradually decreases from bottom to top), the top of the waistline gives a stronger sense of contraction compared to other parts. Therefore, this design places the outer voluminous section above the outer pleated section, and the outer voluminous section also extends to the top of the waistline. This makes the top of the waistline appear loose and voluminous, thus reducing the visual impression of contraction at the top of the waistline. Therefore, placing the outer voluminous section at the top of the waistline creates a greater contrast compared to the previous design, and this contrast can give buyers a stronger visual impact.

[0011] Preferably, as an improvement, the inner lining of the waistband is divided into a fluffy inner lining section and a pleated inner lining section, with the fluffy inner lining section located above the pleated inner lining section; the surface layer of the pleated inner lining section is fixedly bonded to the elastic layer, and there is a gap between the surface layer of the fluffy inner lining section and the elastic layer.

[0012] To address the technical issues of this application, the puffy portion of the waistband in this solution is primarily located on the outer side of the waistband. This makes it easy for buyers to immediately recognize the features of the waistband product. However, this does not mean that it must be located on the outer side of the waistband. In addition to the outer side of the waistband, the puffy portion can also be located on the inner lining of the waistband. This is similar to the outer side of the waistband. Since the inner lining of the waistband is divided into an inner puffy section and an inner pleated section, the surface of the inner puffy section will also give a loose and fluffy visual feeling, rather than a tight and contracted visual feeling. The inner puffy section looks more fluffy (the surface of the outer puffy section floats on the surface, and its appearance is like bubbles).

[0013] Preferably, as an improvement, the surface layer of the inner lining fluffy section and the surface layer of the outer lining fluffy section are integrally connected. This integral connection allows the surface layer at the top of the waistband to also give the buyer a visual impression of being floating on the surface in a bubble-like manner, and the surface layers of the inner lining fluffy section and the outer lining fluffy section transition smoothly together.

[0014] Preferably, as an improvement, the vertical width of the outer surface fluffy section is 2-5cm; the vertical width of the inner surface fluffy section is 0.5-2cm; and the vertical width of the outer surface fluffy section is greater than the vertical width of the inner surface fluffy section.

[0015] Since the outer side puff section is located on the outer side of the waistband and the inner side puff section is located on the inner side of the waistband, the vertical width of the outer side puff section is set to be greater than that of the inner side puff section. This makes the outer side puff section more noticeable and easier for buyers to spot, thus making the unique features of this product more apparent.

[0016] Preferably, as an improvement, it also includes a color developing layer, which is located at the fluffy section on the outer side and is adhered and fixed to the elastic layer.

[0017] Therefore, the color-developing layer ensures that the visual color of the outer fluffy section differs from that of the outer pleated section. This color difference draws the buyer's attention to the fluffy, pleated structure of the outer section, preventing it from appearing inconspicuous due to a uniform color between the two. Furthermore, the color-developing layer and the surface layer on the outer fluffy section also differ in color. This color difference further accentuates the fluffy pleats against the background of the other colors in the developing layer, making the surface fluffy pleats of the outer section even more visually striking.

[0018] Preferably, as an improvement, the elastic layer is provided with multiple elastic elements, which are arranged horizontally and distributed vertically in sequence, with the denier of the elastic elements being 50-280D.

[0019] This waistband not only emphasizes visual appeal but also practical comfort during use. Therefore, the elastic elements are limited to a denier of 50-280D. The thinner elastic elements result in smaller individual elastic strands, reducing the amount of elasticity and thus minimizing wrinkling deformation in the elastic layer. This helps reduce wrinkles on the outer and inner surfaces of the waistband, resulting in smaller wrinkle protrusions. Furthermore, the denser arrangement of the elastic elements divides the deformation wrinkles into smaller segments, further reducing wrinkle protrusions. Therefore, this design minimizes wrinkle protrusions on the waistband surface, resulting in a smoother waist, improved texture and feel against the skin, and reduced marks and indentations.

[0020] Furthermore, by making the elastic element thinner, the waistband can be made thinner. In existing technologies, the elastic element is relatively thick, making it more transparent and noticeable through the surface of the waistband. Therefore, for aesthetic purposes, the waistband surface must use multiple layers of material to prevent the elastic element from showing, but this is detrimental to waistband comfort. In this solution, the elastic element is thinner and can be housed within a thinner waistband without being visible, thus reducing the waistband thickness and improving comfort.

[0021] Therefore, this solution can make the pleats formed by the inner and outer pleats finer, improve the smoothness of the waistline, enhance the delicacy and skin feel, and reduce the formation of marks and imprints.

[0022] Preferably, as an improvement, the elastic element has at least one of the following parameters: The vertical spacing between adjacent elastic elements is 1-5mm; The elastic elongation of the elastic element is 200%-350%; The elastic recovery rate of the elastic component is ≥90%.

[0023] Since the most basic characteristic of a waistband is its elasticity, the comfort of the waistband is closely related to its elasticity. Therefore, in this solution, the inventors further defined the relevant parameters of the elastic component, thereby enabling the waistband to have better elasticity, ensuring that it is not too tight when applied to the body and is not prone to slipping off. By further defining the parameters of the elastic component, the inventors have greatly improved the comfort of the waistband.

[0024] This design controls the spacing of the elastic elements to 1-5mm, avoiding excessive spacing. This ensures that the resulting folds are the correct size and prevents large folds from forming. The folds formed in the elastic layer, the outer surface fold section, and the inner lining fold section are tight folds. Therefore, elastic elements with the above parameters are selected because they have good elasticity and moderate elasticity, which does not cause significant pressure on the waist and prevents the waistband from slipping down.

[0025] In summary, the solution proposed in this application enables the waistband to meet both internal requirements (the elastic layer, the outer side pleated section, and the inner lining pleated section form finer pleats, resulting in tight pleats, high flatness of the waistband, improved smoothness and skin feel, and reduced marks and imprints) and external requirements (visually, the outer side and inner lining pleated sections of this waistband are fluffy, which will not put too much pressure on the skin and has a comfortable visual feel).

[0026] Preferably, as an improvement, the color developing layer is located between the surface layer of the outer fluffy section and the elastic layer; the top of the color developing layer is bent downwards between the surface layer of the inner fluffy section and the elastic layer.

[0027] Therefore, the color-developing layer is also bent between the surface layer and the elastic layer of the inner veneer fluffy section, which can distinguish and display the fluffy surface layer of the inner veneer fluffy section, thus improving the visual effect of the fluffy surface layer of the inner veneer fluffy section.

[0028] Preferably, as an improvement, when setting the color developing layer, the density of the elastic elements on the elastic layer at the fluffy section of the outer surface is greater than the density of the elastic elements on the elastic layer at the wrinkled section of the outer surface; or, The elastic layer at the fluffy section of the outer side has an elastic element that is thicker than the elastic element on the elastic layer at the wrinkled section of the outer side.

[0029] Because the elastic layer in the fluffy section of the outer side has a color-developing layer, while the wrinkled section of the outer side does not contain a color-developing layer, the thickness (number of layers) of the fluffy section of the outer side is greater than that of the wrinkled section of the outer side. Therefore, the density of the elastic element in the fluffy section of the outer side needs to be greater than that of the elastic element in the wrinkled section of the outer side, so that the fluffy section of the outer side has sufficient elastic force to shrink. Alternatively, the elastic layer in the fluffy section of the outer side has an elastic element that is thicker than the elastic element in the elastic layer of the wrinkled section of the outer side. After the elastic element becomes thicker, the elastic force will also increase, so that the fluffy section of the outer side has sufficient elastic force to shrink. Attached Figure Description

[0034] Figure 5 This is a cross-sectional view of the waist circumference. Detailed Implementation

[0035] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings of the instruction manual include: 1. outer side pleated section; 2. outer side fluffy section; 3. inner lining pleated section; 4. inner lining fluffy section; 5. outer side of waistband; 6. inner lining of waistband; 7. elastic layer; 8. surface layer; 9. gap; 10. elastic element; 11. color developing layer; 12.

[0036] The basics are as follows: Figures 1-5 As shown: This embodiment discloses a hygiene product, including a pant body 1 and a waistband located on the pant body 1. The hygiene product can be a disposable absorbent product (including an absorbent core) such as a diaper, pull-up pants, or overnight pants, which can be used to absorb urine for infants or menstrual fluid for adults.

[0037] The main improvement in this embodiment is the improvement of the waist circumference. The pants body is existing technology, so the waist circumference will be mainly described below.

[0038] This embodiment discloses a fluffy and comfortable waistband, the entire waistband being divided into a front waistband (the waistband around the front of the sanitary product) and a back waistband (the waistband around the back of the sanitary product), the structures of the front and back waistbands being basically the same. Whether it's the front or back waistband, combined with... Figure 2As shown, both the front and back waistbands include an elastic layer 8 and a surface layer 9. The elastic layer 8 has a certain degree of elasticity; in this embodiment, the elastic layer 8 is made of fabric. Figure 3 As shown, the elastic layer 8 is provided with multiple elastic elements 11. In this embodiment, the elastic element 11 is spandex filament; however, in other embodiments, it can also be other elastic elements such as rubber bands. In this embodiment, the multiple spandex filaments are horizontally bonded to the elastic layer 8, and the multiple spandex filaments are vertically distributed sequentially on the elastic layer 8. By bonding multiple elastic elements 11 to the elastic layer 8, the elastic layer 8 acquires a certain elasticity. Figure 2 As shown, in this embodiment, the surface layer 9 is also a layer of fabric, and the surface layer 9 is located on the left and right sides of the elastic layer 8, wherein... Figure 2 The right side of the medium elastic layer 8 is the outer side of the waistband (the side of the waistband furthest from the skin when the sanitary product is worn, such as...). Figure 1 (As shown by reference numeral 6 in the attached figure) on one side, Figure 2 The left side of the medium elastic layer 8 is the inner lining of the waistband (the side of the sanitary product that fits against the skin when worn, such as...). Figure 1 As shown by reference numeral 7 in the attached diagram, the top of the outer surface layer 9 on the outer side of the waistband and the top of the inner surface layer 9 on the inner side of the waistband are connected as one piece. Therefore, these two surface layers 9 (the outer surface layer 9 on the outer side of the waistband and the inner surface layer 9 on the inner side of the waistband) clamp the elastic layer 8. In this embodiment, both the elastic layer 8 and the surface layer 9 are made of non-woven fabric, and their thickness is 0.05-0.2mm.

[0039] Combination Figures 1-2As shown, in this embodiment, the outer side 6 of the waistband is divided into an outer side fluffy section 3 and an outer side pleated section 2. The outer side fluffy section 3 is located above the outer side pleated section 2 and extends upward to the top of the waistband. The main difference between the two sections is that the surface layer 9 of the outer side pleated section 2 is fixedly attached to the elastic layer 8 by adhesive, while there is a gap 10 between the surface layer 9 and the elastic layer 8 of the outer side fluffy section 3. Therefore, the surface layer 9 and the elastic layer 8 of the outer side fluffy section 3 are not bonded together, while the surface layer 9 and the elastic layer 8 of the outer side pleated section 2 are bonded and fixed together. In this way, when the elastic layer 8 on the outer side pleated section 2 contracts normally, since the elastic layer 8 and the surface layer 9 are connected as one, the elastic layer 8 causes the surface layer 9 to contract together, forming multiple tight pleats on the surface of the outer side pleated section 2. These tight pleats are formed by the contraction of the waistband under the action of elasticity. As for the outer fluffy section 3, since the surface layer 9 of the outer fluffy section 3 is not bonded and fixed to the elastic layer 8, the elastic force of the elastic layer 8 will not act on the surface layer 9 of the outer fluffy section 3. Therefore, the surface layer 9 of the outer fluffy section 3 will not form tight wrinkles as the elastic layer 8 contracts. When the elastic layer 8 of the outer fluffy section 3 contracts, the surface layer 9 of the outer fluffy section 3 only forms larger wrinkles (for example, wrinkles with a horizontal width of 0.5 cm or more). These wrinkles are not tight; they are relatively fluffy (referred to as fluffy wrinkles). Furthermore, the surface layer 9 and the elastic layer 8... With gap 10 and surface layer 9 appearing bubble-like, the fluffy outer section 3 gives a loose visual impression, unlike the tight, constricting visual impression of the wrinkled outer section 2. The fluffy outer section 3 looks more fluffy (the surface layer 9 of the fluffy outer section 3 floats on the surface and appears bubble-like). Compared to the previous version where the entire waistband was tightly wrinkled, this avoids consumers mistakenly believing that the waistband puts too much pressure on the waist and may cause discomfort to the baby. It gives buyers a better visual impression, and consumers will be more inclined to favor sanitary products containing this waistband, which is conducive to increasing product sales.

[0040] In this embodiment, the vertical width of the fluffy section 3 on the outer side is 2-5cm, specifically 3cm.

[0041] The above describes how the outer side 6 of the waistband is designed so that the surface layer 9 is not bonded to the elastic layer 8, forming a fluffy section 3 on the outer side, giving a fluffy, loose, and comfortable feel. Of course, in a more preferred embodiment, similarly, the inner waistband lining 7 can also be divided into a fluffy inner lining section 5 and a wrinkled inner lining section 4, combined with... Figure 1 and Figure 2As shown, the inner lining fluffy section 5 is located above the inner lining pleated section 4, extending upwards to the top of the waistband. The inner lining pleated section 4 operates on the same principle as the outer lining pleated section 2, with its surface layer 9 bonded to the elastic layer 8, resulting in tight pleats. The inner lining fluffy section 5 operates on the same principle as the outer lining fluffy section 3, with a gap 10 between its surface layer 9 and the elastic layer 8. In this gap, the surface layer 9 and the elastic layer 8 are not bonded together, thus creating fluffy pleats.

[0042] Although both the outer side 6 and the inner surface of the waistband have fluffy sections and pleated sections, the vertical width of the fluffy section 5 on the inner surface is smaller than the vertical width of the fluffy section 3 on the outer surface. In this embodiment, the vertical width of the fluffy section 5 on the inner surface is 0.5-2cm, specifically 1cm. Since the vertical widths of the outer side 6 and the inner surface 7 of the waistband are basically the same, when the vertical width of the fluffy section 5 on the inner surface is smaller than the vertical width of the fluffy section 3 on the outer surface, the vertical width of the pleated section 2 on the outer surface is smaller than the vertical width of the pleated section 4 on the inner surface. In this embodiment, the vertical width of the pleated section 2 on the outer surface is 3-10cm, specifically 5cm.

[0043] In existing technologies, waistbands and sanitary products are generally made of white non-woven fabric. If the entire outer side pleated section 2 and the outer side fluffy section 3 are the same color, both white, it is not easy to notice the unique design of the outer side fluffy section 3. In some embodiments, this can be further optimized. Combined with... Figure 4 As shown, the waistband also includes a color-developing layer 12, which is located at the outer fluffy section 3 and is bonded and fixed to the elastic layer 8. The color-developing layer 12 is located between the surface layer 9 of the outer fluffy section 3 and the elastic layer 8. Simultaneously, the top of the color-developing layer 12 is bent downwards between the surface layer 9 of the inner fluffy section 5 and the elastic layer 8. In this embodiment, the color-developing layer 12 is made of non-woven fabric with a thickness of 0.05-0.5mm, and can be set to colors such as blue or red.

[0044] By setting a color-developing layer 12, people can see the color of the color-developing layer 12 through the surface layer 9. The setting of the color-developing layer 12 makes the color of the outer fluffy section 3 visually different from the color of the outer wrinkled section 2. This color difference makes buyers pay more attention to the fluffy structure of the outer fluffy section 3. In addition, the colors of the color-developing layer 12 and the surface layer 9 on the outer fluffy section 3 are also different. The difference between these two colors can highlight the fluffy wrinkles of the surface layer 9, making the fluffy wrinkles of the outer fluffy section 3 more visually obvious. This avoids the fluffy wrinkle structure of the surface layer 9 not being prominent due to the elastic layer 8 and the surface layer 9 being the same color. Since the inner veneer fluffy section 5 also has a color-developing layer 12, the color difference between the inner veneer fluffy section 5 and the inner veneer wrinkled section 4 is also quite obvious, so that the inner veneer fluffy section 5 and the inner veneer wrinkled section 4 can be easily distinguished; at the same time, under the effect of the color-developing layer 12, the fluffy wrinkles of the surface layer 9 of the inner veneer fluffy section 5 can be highlighted, so that the fluffy wrinkles of the surface layer 9 of the inner veneer fluffy section 5 have a more obvious visual effect.

[0045] In some embodiments, when the color developing layer 12 is provided, the density of elastic elements 11 on the elastic layer 8 at the fluffy section 3 of the outer side is greater than the density of elastic elements 11 on the elastic layer 8 at the wrinkled section 2 of the outer side. For example, the spacing between adjacent elastic elements 11 on the elastic layer 8 at the fluffy section 3 of the outer side is 0.5 mm, while the spacing between adjacent elastic elements 11 on the elastic layer 8 at the wrinkled section 2 of the outer side is 1 mm. Alternatively, the elastic layer 8 at the fluffy section 3 of the outer side has elastic elements 11 that are thicker than those on the elastic layer 8 at the wrinkled section 2 of the outer side. For example, the elastic layer 8 at the fluffy section 3 of the outer side has four additional thick spandex filaments, with a spacing of 0.5 cm between adjacent thick spandex filaments, and the denier of the thick spandex filaments is 280 denier or higher. In this way, due to the presence of the color developing layer 12, the thickness of both the elastic layer 8 and the elastic layer 8 will increase, thus requiring more or thicker elastic elements 11 to ensure the elasticity of the elastic layer 8.

[0046] This concludes the description of the main improvements to the waistband in this embodiment, the fluffy structure and principle of the corresponding fluffy sections on the outer side 6 and inner side 7 of the waistband. By creating fluffy pleats (wide and bubble-like pleats) on the surface 9 of the fluffy section 3 on the outer side and the surface 9 of the fluffy section 5 on the inner side, it gives the visual impression of less pressure on the waistband. However, since the waistband is intended for infants, whose skin is delicate, this product's waistband must not only visually give the impression of less pressure on the waistband, but also ensure actual tactile comfort for infants, reducing marks and indentations. Therefore, the pleats on the outer side pleat section 2 and the inner side pleat section 4 in this embodiment need to be more delicate, smaller, and smoother.

[0047] Specifically, the nonwoven fabric in the corresponding part deforms under the elastic force of the elastic element 11, forming tight folds on the surface of the waistband. The peak height of these tight folds in the naturally relaxed state is ( Figure 5 E0, which is the distance from the peak of the pleat surface to the trough of the pleat gap in the waistband, is 0.05-1mm. The distance between adjacent pleat gaps in a naturally relaxed state ( Figure 5 The distance shown in A is 0.2-2mm. The natural relaxed state refers to the waist circumference not being stressed or stretched, that is, the natural contraction state. These pleats have small protrusions, minimal protrusion from the waist circumference, are closely arranged, and are thinner, more breathable, and significantly softer. They also have the advantages of high flatness and delicate feel. Therefore, when worn, they will not leave large or obvious marks on the waist, greatly reducing the occurrence of marks and making them more comfortable to wear.

[0048] Furthermore, the implementation of tight wrinkles is also related to the parameter settings of the elastic element 11, which has at least one of the following parameters: The elastic element 11 has a denier of 50-280D, more specifically 70-140D, and the elastic element 11 is finer than the prior art; Figure 3 The spacing between adjacent elastic elements 11 in the vertical direction is 1-5mm, specifically 1mm; The elastic elongation of elastic element 11 (elastic elongation is the percentage of elongation of the specimen at breaking strength relative to the initial length; the test method for elongation at breaking is disclosed in the textile industry standard FZ / T50006-94 of the People's Republic of China) is 200%-350%; The elastic recovery rate of the elastic element 11 (calculated as: (100%*(L1-L2) / (L1-L0), where L0 is the original straight length of the elastic element 11 without external force; L1 is the length of the elastic element 11 after being stretched by external force; L2 is the straight length of the elastic element 11 after a certain period of time without external force) is ≥90%. The effect is better when multiple parameters of the elastic element 11 are simultaneously present; therefore, it is preferable to have all of the above parameters of the elastic element 11. When the elastic element 11 of the waistband has the above parameters, the pressure value, flatness, and thickness of the waistband can meet the corresponding requirements, resulting in a more comfortable waistband.

[0049] This type of delicate, small, and more comfortable tight fold is existing technology, and it has been disclosed in Chinese Patent Publication No. CN117618191A and Chinese Patent Announcement No. CN221600431U. This embodiment will not go into detail about the more specific formation method and the more detailed parameters of the tight fold, but you can refer to the fold setting method in the prior art.
