Description

Technical Field

[0001] This utility model relates to the field of disposable hygiene products, and in particular to a dry and leak-proof diaper. Background Technology

[0002] Existing disposable diapers mainly consist of a liquid-permeable top layer, a core layer, a liquid-impermeable bottom layer, leak-proof side panels, and Velcro. During production, the leak-proof side panels are formed by folding a hydrophobic layer over an elastic band and then laminating them onto the liquid-impermeable bottom layer. This structure is complex, and the narrow width of the side panels during lamination can lead to misalignment, affecting product quality. Furthermore, the liquid-permeable top layer uses absorbent non-woven fabric. When urine enters the diaper, most of it diffuses and is absorbed in the middle. Once the liquid-permeable top layer becomes wet, the urine spreads throughout, causing the entire layer to become damp. This results in a large area of ​​the skin coming into contact with urine, and prolonged wear can easily lead to diaper rash and unpleasant odor in babies.

[0003] Chinese patent application number 201921937638.2 discloses an anti-backflow diaper, comprising a diaper body with waistbands at both ends and side leakage guards on both sides. The diaper body consists of, from top to bottom, a liquid-permeable surface layer, a drainage layer, a composite waterproof fabric layer, and an absorbent core. The liquid-permeable surface layer has indentations, and the drainage layer has evenly distributed drainage channels in a funnel shape. The larger end of the drainage channel is located on the drainage layer, and the smaller end extends into the absorbent core. When the liquid-permeable top layer of this diaper becomes wet, the moisture spreads throughout the entire liquid-permeable top layer, causing extensive contact between the skin and urine. Prolonged wear can easily lead to diaper rash and unpleasant odor in babies. Utility Model Content

[0004] Therefore, to address the aforementioned problems, this invention proposes a dry, leak-proof diaper. It solves the technical issues of diaper rash and unpleasant odor that often occur in babies when wearing diapers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dry, leak-proof diaper includes a diaper body. The diaper body comprises a hydrophobic layer, a core layer, and a liquid-impermeable bottom layer arranged sequentially from top to bottom. The hydrophobic layer has a hollowed-out section in the middle. More than three-quarters of the area of ​​the core layer corresponds to the hollowed-out section. The left and right sides of the hydrophobic layer are fixed to the liquid-impermeable bottom layer. Two fixing parts are formed between the hydrophobic layer and the liquid-impermeable bottom layer along the length direction. A folding part is provided on the hydrophobic layer outside the fixing parts. The folding part is folded inward to cover the elastic band to form a leak-proof side. The diaper body also has Velcro.

[0007] Further:

[0008] The core layer extends beyond the cutout on both sides of the hydrophobic layer, and the left and right sides of the cutout on the hydrophobic layer abut against the core layer.

[0009] The hydrophobic layer has a first infiltration section at both the front and rear ends, and the first infiltration section has a plurality of first through holes.

[0010] The number of first through holes in the first seepage section gradually decreases along the outer direction.

[0011] The hydrophobic layer has a second infiltration section at both the left and right ends, and the second infiltration section has a plurality of second through holes.

[0012] The number of second through holes in the second seepage section gradually decreases along the outer direction.

[0013] The core layer is provided with two first protrusions arranged along the length direction, and a guide groove is formed between the two first protrusions.

[0014] The left and right ends of the hollowed-out inner side extend to the outer edges of the two first protruding strips, respectively.

[0015] The core layer is provided with two second protrusions arranged along the length direction. The two second protrusions are respectively connected to the front and rear ends of the first protrusion, and a buffer groove is formed between the two first protrusions and the two second protrusions.

[0016] The front and rear ends of the hollowed-out inner side extend to the outer edges of the two first protruding strips, respectively.

[0017] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0018] This invention replaces the traditional liquid-permeable top layer with a hydrophobic layer. The folded portions on both sides of the hydrophobic layer fold inward to cover the elastic band, forming a leak-proof barrier. This eliminates the need for a separate leak-proof barrier, simplifying the manufacturing process, saving materials, and reducing production costs. Urine can reach the core layer through the perforations in the hydrophobic layer, which repels water, preventing urine from wetting the body and causing diaper rash and odor in babies. Furthermore, the first through-hole allows urine to seep downwards; when there is excessive urine, a small amount can seep through the first through-hole, preventing back or front leakage. Similarly, the second through-hole allows urine to seep downwards; when there is excessive urine, a small amount can seep through the second through-hole, preventing side leakage. Furthermore, the first protrusion has a guiding and blocking function. Finally, the buffer groove has a blocking and buffering function, preventing leakage and blocking liquid flow onto the hydrophobic layer. Attached Figure Description

[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0029] refer to Figure 1 and Figure 2 This embodiment provides a dry and leak-proof diaper, including a diaper body 1. The diaper body 1 includes a hydrophobic layer 11, a core layer 12, and a liquid-impermeable bottom layer 13 arranged sequentially from top to bottom. The hydrophobic layer 11 has a hollow 110 in the middle. More than three-quarters of the area of ​​the core layer 12 corresponds to the hollow 110. The left and right sides of the hydrophobic layer 11 are fixed to the liquid-impermeable bottom layer 13. The left and right sides of the core layer 12 on the hydrophobic layer 11 extend beyond the hollow 110. The left and right sides of the hydrophobic layer 11 located at the hollow 110 abut against the core layer 12. Two fixing parts 14 are formed between the hydrophobic layer 11 and the liquid-impermeable bottom layer 13 along the length direction. A folding part is provided on the outside of the fixing part 14 on the hydrophobic layer 11. The folding part folds inward to cover the elastic band 112 to form a leak-proof side 111. The diaper body 1 is also provided with Velcro 15.

[0030] refer to Figure 1In one embodiment, a skin-friendly layer 120 is provided on the core layer 12, which can isolate and keep the material dry, and also prevent polymer leakage. The skin-friendly layer 120 may also be omitted, depending on the specific circumstances.

[0031] refer to Figure 3 In another embodiment, the hydrophobic layer 11 has a first infiltration portion 113 at both its front and rear ends, and the first infiltration portion 113 has a plurality of first through holes 114, the number of first through holes 114 in the first infiltration portion 113 gradually decreasing along the outer direction. (Reference) Figure 4 In another embodiment, the hydrophobic layer 11 has a second infiltration portion 115 at both the left and right ends, and the second infiltration portion 115 has a plurality of second through holes 116, the number of second through holes 116 in the second infiltration portion 115 gradually decreases along the outer direction.

[0032] refer to Figure 5 and Figure 6 In one embodiment, the core layer 12 has two first protrusions 121 arranged along its length, and a guide groove 122 is formed between the two first protrusions 121. The left and right ends of the inner side of the hollow 110 extend to the outer edges of the two first protrusions 121, respectively. (See reference) Figure 7 In another embodiment, the core layer 12 is provided with two second protrusions 123 arranged along the length direction. The two second protrusions 123 are respectively connected to the front and rear ends of the first protrusion 121. A buffer groove 124 is formed between the two first protrusions 121 and the two second protrusions 123. The front and rear ends of the inner side of the hollow 110 extend to the outer edge of the two first protrusions 121 respectively.

[0033] The method of using this utility model is as follows:

[0034] The diaper body 1 is worn on the human body. Urine flows into the core layer 12 through the perforation 110. The core layer 12 absorbs the urine. The hydrophobic layer 11 has a water-repellent function, so urine will not wet the human body over a large area, preventing the baby from getting diaper rash and odor. During the manufacturing of the diaper body 1, the folded parts on both sides of the hydrophobic layer 11 are folded inward to cover the elastic band 112 to form a leak-proof side panel 111. There is no need to apply a separate leak-proof side panel 111, which simplifies the manufacturing process, saves materials, and reduces production costs.
