Description

Technical Field

[0001] This utility model relates to the field of personal care technology, specifically to a breathable baby pull-up diaper with a wide waistband. Background Technology

[0002] Existing pull-up diapers primarily determine their breathability through the breathability of the outer lining. However, this outer lining tends to bunch up due to the contraction of elastic materials, significantly reducing overall breathability. Furthermore, existing pull-up diapers cannot adjust to different body shapes or times of day (e.g., a protruding abdomen after a meal versus a flat abdomen at other times) to ensure breathability, and they lack automatic elasticity adjustment, resulting in compromised comfort.

[0039] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0040] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0041] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0043] Combination Figures 1 to 10As shown in the embodiment, this invention proposes a breathable waistband baby pull-up diaper, including a main body and an inner lining 3. The inner lining 3 is connected to the inside of the main body. The main body contains a composite elastic material 26. The main body has a front waist and / or rear ...

[0044] In some specific implementations, the holes can be arranged in a matrix or other shapes, such as: holes arranged in a flush configuration, or holes arranged in a single heart shape (e.g., forming...). Figure 1 The structure formed by the arrangement of the first hole 9 shown in the figure), the holes are arranged in a diamond shape and then in a heart shape (e.g., forming a structure). Figures 2 to 4 The structure formed by the arrangement of the second hole 10 shown), the holes are distributed in a net-like staggered pattern (e.g.: Figure 5 and Figure 6 (The structure formed by the arrangement of the third 12 holes shown in the diagram). All holes are generally made according to the same size and specification, creating a diamond pattern when worn, and automatically adjusting the actual size and tightness of the holes according to the baby's different states. Of course, the pattern of the holes and the pattern when the holes are open can also be adjusted as needed. The staggered arrangement of adjacent rows of holes can improve the product's transverse and longitudinal breaking strength.

[0045] The aforementioned main body includes an outer lining and an inner lining, with an elastic material laminated between the inner and outer linings. Both the outer and inner linings described herein can be one of spunbond nonwoven fabric, hot-air nonwoven fabric, thermoforming nonwoven fabric, or meltblown nonwoven fabric.

[0046] The aforementioned elastic material 26 may be one of the following: elastic rubber band (elastic band denier 120D-1100D), elastic film, elastic nonwoven fabric (one or more of SBS block copolymer elastomer, POE polyolefin elastomer, TPU polyurethane, EPDM ethylene propylene diene monomer rubber elastomer and their compositions or modifiers).

[0047] In some specific implementations, the aforementioned holes are arranged to avoid the side seal 2 and / or the inner fitting 3; at least one edge of the hole corresponding to the elastic material 26 in the corresponding waist and abdomen area is connected to the elastic material 26.

[0048] Generally, the aforementioned dot-cut hole area is based on the side seam 2 of the product (breathable waistband baby pull-up diaper). Vertically, the height A of the side seal 2 from bottom to top (from the side closest to the center of the breathable waistband baby pull-up diaper to the side furthest from the center of the breathable waistband baby pull-up diaper) is defined as the longitudinal area L0 of the dot-cut hole area, which is 0-25 mm from the bottom and 0-25 mm from the top of the side seal on the waist and abdomen area. The dot-cut hole area is located on both sides of the inner packaging 3.

[0049] In some specific implementations, when the elastic material 26 is an elastic rubber band:

[0050] The distance C from the transverse area W0 of the horizontally disconnected hole region to the side seal 2 is 0-30 mm to reduce the impact on the connection strength of the side seal 2 when the hole is opened; the distance D from the transverse area W0 to the inner component 3 is 0-30 mm to avoid leakage caused by damage to the inner component 3 when the hole is opened. Horizontally, the spacing W between two adjacent rows of holes is 3-15 mm. If the transverse hole spacing W is too large, good air permeability cannot be achieved; if the transverse hole spacing W is too small, elasticity will be completely lost and the product will be easily torn. The transverse breaking strength of the elastic waistband after opening according to this hole design is ≥1 N / 25 mm. Vertically, the length L of the hole is 3-15 mm, and the spacing L3 between two adjacent holes is 2-8 mm, allowing for simultaneous continuous point-disconnection of multiple elastic bands. When the spacing L3 of the longitudinal openings is too large, it cannot achieve good air permeability and form a good diamond-shaped hole effect. When the spacing L3 of the openings is too small, it will cause the product to break easily in the longitudinal direction. The longitudinal breaking strength of the elastic waistband after opening according to this opening design is ≥1N / 25mm.

[0051] In some embodiments, when the elastic material 26 is an elastic membrane:

[0052] In the horizontal direction, the distance C from the horizontal region W0 to the side seal 2 is 0-30 mm to reduce the impact on the connection strength of the side seal 2 when opening holes; the distance D from the horizontal region W0 to the inner component 3 is 0-30 mm to avoid leakage caused by damage to the inner component 3 when opening holes. In the horizontal direction, the spacing W between two adjacent rows of holes is 3-15 mm. If the horizontal hole spacing W is too large, it will not achieve a good air permeability effect; if the horizontal hole spacing W is too small, it will lead to complete loss of elasticity and the product will be easily torn. The horizontal breaking strength of the elastic waistband after opening holes according to this hole design is ≥1N / 25mm. In the vertical direction, the length L of the hole is 5-15 mm, and the spacing L3 between two adjacent holes is 4-10 mm. Multiple elastic bands can be continuously opened at the same hole at the same time. When the spacing L3 of the longitudinal openings is too large, good air permeability cannot be achieved, resulting in a good diamond-shaped hole effect. If the spacing L3 is too small, the product will be prone to longitudinal breakage. According to this opening design, the longitudinal breaking strength of the elastic waistband after opening should be ≥1N / 25mm. When using this elastic material to manufacture products, a combination of ultrasonic drilling and knife-point drilling can be used to perforate the elastic material. When using ultrasonic drilling, due to the different materials of the elastic membrane, outer lining, and inner lining, the membrane can be punctured, but the outer and inner linings remain bonded, achieving a sealing effect. Ultrasonic point-breaking holes are then arranged in the adjacent un-pointed areas of the knife-point drilling.

[0053] In some specific implementations, when the elastic material 26 is an elastic nonwoven fabric:

[0054] In the horizontal direction, the distance C from the horizontal area W0 to the side seal 2 is 10-30 mm, and the distance D from the horizontal area W0 to the inner packaging 3 is 0-30 mm, avoiding the area where the inner packaging 3 is located to prevent damage to the inner packaging 3 and leakage when opening holes. The spacing W between two adjacent rows of holes is 5-15 mm. If the horizontal hole spacing W is too large, it will not achieve good air permeability; if the horizontal hole spacing W is too small, it will lead to complete loss of elasticity and the product will be easily torn. The horizontal breaking strength of the elastic waistband after opening holes according to this hole design is ≥1N / 25mm. In the vertical direction, the length L of the hole is 3-15 mm, and the spacing L3 between two adjacent holes is 4-10 mm. The longitudinal breaking strength of the elastic waistband after opening holes according to this hole design is ≥1N / 25mm.

[0055] In some specific implementations, the holes corresponding to the elastic material in the waist and abdomen area on at least one side are polygonal, and at least one corner of the hole corresponding to the elastic material in the waist and abdomen area on one side is connected to the elastic material. In some specific implementations, the size and shape of the holes on the same pull-up diaper are consistent. When worn and stretched, the holes can be quadrilateral, preferably rhomboid, and two non-adjacent corners of the hole correspond to the corresponding elastic material 26. In this case, the hole not only serves as an opening but also acts as a point break for the elastic material 26. This breathable waistband pull-up diaper can automatically adjust the actual size and tightness of the holes according to the baby's different states.

[0056] In some specific implementation methods, such as Figures 1 to 3 As shown, the outer lining and the inner lining are also bonded together with S-leg elastic bands 7.

[0057] The aforementioned internal structure 3 can be as follows: the internal structure 3 includes a bottom membrane 24, a three-dimensional protective enclosure 6 located on the top layer of the bottom membrane, and a double-layer absorbent body wrapped with a surface non-woven fabric 19. The three-dimensional protective enclosure 6 is provided with multiple first elastic materials 20. The surface non-woven fabric 19 wraps around the bottom membrane 24 from the bottom, and second elastic materials 21 are provided on both sides of the surface non-woven fabric 19 to form a suspended core structure. The first elastic material 20 and the second elastic material 21 can both be elastic rubber bands, with a tensile ratio of 1.6-2.5 and a denier of 470-780 dtex. The surface nonwoven fabric 19 can be a double-layer composite structure, formed by hot pressing or ultrasonic pressing of the upper surface nonwoven fabric 18 and the lower surface nonwoven fabric 17. The surface nonwoven fabric 19 can be provided with 3D embossing. The double-layer absorbent can be formed by combining an upper absorbent 22 and a lower absorbent 23 of the same size (or by two absorbents of different sizes, which can be directly achieved by existing technology, so it will not be described in detail here). Both the upper absorbent 22 and the lower absorbent 23 can include a core and a wrapping layer. The core can be one or more of wood pulp mixture, toilet paper, nonwoven fabric, absorbent paper, and dust-free paper. The wrapping layer can be one or more of toilet paper, nonwoven fabric, absorbent paper, and dust-free paper. The structures and components involved can all be implemented using existing technologies, so they will not be described in detail here. In addition, the interior 3 can also directly adopt other existing interior structures.

[0058] In some specific implementation methods, combined Figures 2 to 5As shown, after the inner component 3 is combined with the main body, an inner elastic region 5 is formed corresponding to the inner component. The elastic material 26 in the inner elastic region 5 is treated to eliminate bullets. The bullet-eliminating length X3 is 0.8-5 mm, preferably 3 mm; the spacing X2 between bullets in the same row is 2-12 mm, preferably 9 mm; the spacing X between bullets in the same column is 1-6 mm, preferably 3 mm; the distance X1 between the bottom of the upper bullet and the top of the lower bullet in two adjacent bullets in the same column is 0-2 mm, preferably 1 mm.

[0059] Taking elastic material 26 as an example of elastic rubber band, during the preparation of the waist and abdomen area, while the elastic material 26 in the inner elastic area 5 is subjected to elasticity reduction treatment, the rubber band can also be broken and perforated between the edge 0-30mm (preferably 25mm) of the side seal 2 in the transverse direction of the product and the two edges 0-30mm (preferably 25mm) of the inner 3. The specific rules for point-cutting are as follows: For holes to be drilled in a matrix or other arrangement, the horizontal spacing W between two adjacent holes is set to 3-15 mm, preferably 4 mm; the vertical length L of the hole is set to 3-15 mm, preferably 9 mm; the vertical spacing L3 between two adjacent holes is set to 2-8 mm, preferably 4 mm. By setting the holes, one or more elastic rubber bands can be continuously cut simultaneously, preferably one. The preferred point-cutting area in the longitudinal direction of the product is to make point-cutting holes from the inner end down one elastic spandex filament, for a total of 5 rows of point-cutting, with the point-cutting length centered on the elastic rubber band.

[0060] Point-cutting and spring-loaded removal can be performed at separate stations or on the same cutting roller. When performed on the same cutting roller, methods such as... Figure 7 The cutter roller shown has an internal anti-bomb cutter 14 and two side point-breaking punching cutters 15 and 16. A shim 13 is provided between the internal anti-bomb cutter 14, the two side point-breaking punching cutters 15 and 16 and the central shaft of the cutter roller. The internal anti-bomb cutter 14 and the two side point-breaking punching cutters 15 and 16 are three independent control modules. The height H8 of the shim 13 of the three modules can be adjusted to cut the two side point-breaking punching areas and the anti-bomb treatment areas to different depths, so as to minimize the damage to the product by the internal anti-bomb area and completely puncture the two side point-breaking punching areas.

[0061] After completing the internal bulletproofing and elastic band point-cutting, the product is cut into O-shapes to form leg rings. Then, the product waist is folded inwards, followed by folding the product in half front and back, and then ultrasonically sealing and cutting the sides to form side seals. The complete product is then folded and packaged.

[0062] Furthermore, the outer lining can be laminated with S-shaped leg elastic bands 7. After the inner lining is laminated with waist elastic bands 26, the inner and outer linings are laminated and then cut into elastic front waist and abdomen areas (front elastic waistband 4) and back waist and abdomen areas (back elastic waistband 8). After being laminated with the inner packaging 3, the elastic area 5 of the inner packaging is treated to remove elasticity and perforated on both sides. Then, R-cut to form leg loops, then fold the product waistband inward, then fold the product in half front and back, and perform ultrasonic sealing and cutting on the sides to form a complete product for folding and packaging.

[0063] Combination Figures 9 to 11 As shown, when the baby is full, the bulging of the belly provides outward support to the product. At this time, the holes will enlarge to help dissipate heat, and the elastic material 26 corresponding to the holes is cut into several independent elastic waistband areas 11 by the holes, which can reduce the pressure of the product on the baby's abdomen.

[0064] refer to Figure 10 When an infant is full, the bulge in their abdomen causes the height of H1' to increase. At this time, H1' > H1. The length F2 stretched by the elastic band is calculated using the formula F2 = √H1² + (1 / 2R)², where R is determined by the infant's waist circumference, specifically half of the infant's waist circumference. Therefore, when H1 increases, the length stretched by the elastic band also increases, the stretch ratio becomes larger, and the tension at both ends of the hole increases, thus increasing breathability. If the infant's waist circumference R is larger, according to the formula F2 = √H1² + (1 / 2R)², under the same conditions, because R is larger, the breathability obtained by the infant also increases.

[0065] The pressure exerted on the infant by the product primarily comes from force F, which is determined by forces F1 and F2. According to the formula F = √(F1² + F2² - 2F1F2COS²θ), when the infant is full, the bulging of the abdomen causes the height H1' to increase. At this time, H1' > H1, and the stretched length F2 of the elastic band increases, resulting in an increased tensile force. Consequently, the force F also increases, creating a feeling of constriction. By cutting the elastic waistband into several independent elastic waistband sections 11, the lengths of F1 and F2 are shortened, thereby reducing forces F1 and F2. This reduces the resultant force F of F1 and F2, thus reducing the pressure on the abdomen.

[0066] Similarly, for overweight infants, their length H and lengths F1 and F2 are relatively large. This can reduce the feeling of restriction on the infant by the product and achieve a comfortable feeling.

[0067] The aforementioned baby pull-up diapers can be two-piece Q-pants with elastic bands, a waist length of 380 mm, side seams of 130 mm, and elastic band spacing of 120 mm. The style, waist length, side seam length, and elastic band spacing of the baby pull-up diapers can all be adjusted as needed. This is not the inventive point of this application and can be directly implemented using existing technology; therefore, it will not be elaborated further.

[0068] Combination Figure 11 As shown, when the baby walks, the elastic waistband is divided into several independent elastic areas 11, which can better fit the baby's abdominal curve and adjust itself according to the different body shapes of the babies. As the baby's range of motion increases, the product will be stretched in the X and Z directions (directions perpendicular to the height of the body) (during movement, the height of the body, i.e., the Y direction, will only shift up and down, and this direction has no elasticity and has little impact on the holes), so the holes will also become larger, thereby helping to dissipate heat.

[0069] The aforementioned undisclosed matters can be directly implemented using existing technologies, so they will not be elaborated upon here.

[0070] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
