Description

Technical Field

[0001] This utility model relates to the field of baby products technology, specifically a fast-absorbing and leak-proof baby pull-up diaper. Background Technology

[0002] Pull-up diapers are a transitional item between diapers and regular underwear. They are specially designed for toddlers who are learning to walk. Pull-up diapers are perfect for active babies who are starting to roll over, sit up, crawl, or walk. No matter how much the baby moves, they can be easily put on and taken off. Pull-up diapers feature a 360-degree elastic waistband design that dynamically conforms to the baby's tummy.

[0003] For example, a multi-layered core leak-proof pull-up diaper with announcement number "CN210521215U" uses superabsorbent polymer (SAP) particles to quickly absorb water, increasing the absorption speed of the absorbent core. The SAP's water-locking properties prevent backflow after absorption, and the non-woven fabric prevents clumping, improving the baby's comfort. However, this multi-layered core leak-proof pull-up diaper expands after absorbing urine, which can compress the baby's crotch and buttocks, causing discomfort. Furthermore, when the baby rolls around in sleep, some urine can leak out, soaking the sheets. Utility Model Content

[0004] The purpose of this invention is to solve the problem that pull-up diapers expand after absorbing urine, which can cause discomfort to the baby's crotch and buttocks due to compression. Additionally, the multi-layer core leak-proof pull-up diapers can leak urine when the baby rolls around in their sleep, causing the sheets to get wet. Therefore, this invention proposes a fast-absorbing leak-proof baby pull-up diaper.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a quick-absorbing leak-proof baby pull-up diaper, including a diaper body and leg openings. The diaper body has leg openings on both sides. The diaper body has a protective structure inside, which includes a conical groove and a protrusion. The inner wall of the conical groove has multiple through holes. The conical groove is machined on the inner side of the skin-friendly layer. The protrusion is machined on the outer side of the diaper body. An absorbent stick is installed inside the protrusion. The outer wall of the absorbent stick is in contact with the absorbent cotton layer.

[0007] Preferably, an elastic waistband is installed on the upper part of the trousers, and leak-proof side panels are installed on the outer sides of the leg openings.

[0008] Preferably, a moisture-absorbing cotton layer is installed on the inner side of the pants, and an absorbent core is installed on the inner side of the moisture-absorbing cotton layer.

[0009] Preferably, a flow guiding layer is installed on the inner side of the liquid-absorbing core, and a non-woven fabric layer is installed on the inner side of the flow guiding layer.

[0010] Preferably, a skin-friendly layer is installed on the inner side of the nonwoven fabric layer.

[0011] This invention proposes a quick-absorbing, leak-proof baby pull-up diaper. The advantages are as follows: through the cooperation of the diaper body and the protective structure, the baby's urine can easily enter the non-woven fabric layer through the through-holes in the conical groove. The absorbent stick can further absorb urine that cannot be stored on the absorbent surface and store it inside the protrusions. This allows for rapid absorption of urine through the conical grooves, while also reducing the possibility of the diaper body swelling and compressing the baby's crotch and buttocks, increasing the baby's comfort. The combination of the protrusions and the absorbent stick allows for the storage of some urine, reducing leakage when the baby rolls around in their sleep, thus preventing leaks and soaking the sheets.

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] See attached document Figure 1-5In this embodiment, a quick-absorbing leak-proof baby pull-up diaper includes a diaper body 2 and leg openings 10. Leg openings 10 are machined on both sides of the diaper body 2. A protective structure 4 is provided inside the diaper body 2. The protective structure 4 includes a conical groove 401 and a protrusion 403. Multiple through holes 402 are installed on the inner wall of the conical groove 401. The conical groove 401 is machined on the inner side of the skin-friendly layer 9. The protrusion 403 is machined on the outer side of the diaper body 2. A microporous breathable membrane is installed on the inner wall of the diaper body 2, which can play a role in preventing leakage. An absorbent stick 404 is installed inside the protrusion 403. The absorbent stick 404 is made of superabsorbent polymer resin and has good absorbency. The outer wall of the absorbent stick 404 is in contact with the moisture-absorbing cotton layer 5.

[0020] An elastic waistband 1 is installed on the upper part of the pant body 2. Leak-proof side panels 3 are installed on the outside of the leg openings 10. The leak-proof side panels 3 adopt a raised double-layer outward folding design, which can provide double-layer leak protection, ensuring safety and comfort. A moisture-absorbing cotton layer 5 is installed on the inside of the pant body 2. A liquid-absorbing core 6 is installed inside the moisture-absorbing cotton layer 5. The liquid-absorbing core 6 is made of flexible silicone sheet structure. A flow-guiding layer 7 is installed inside the liquid-absorbing core 6. The flow-guiding layer 7 is made of perforated membrane material, which can realize rapid liquid conduction. A non-woven fabric layer 8 is installed inside the flow-guiding layer 7. A skin-friendly layer 9 is installed inside the non-woven fabric layer 8. The skin-friendly layer 9 is made of ultra-soft non-woven fabric.

[0021] Working principle:

[0022] When using quick-absorbing leak-proof baby pull-ups:

[0023] The operator puts the leg openings 10 and the pants 2 on the baby and secures the pants 2 with the elastic waistband 1. The baby's urine can easily enter the non-woven fabric layer 8 through the through holes 402 on the conical groove 401. At the same time, the absorbent holes on the skin-friendly layer 9 can also absorb the baby's urine. The non-woven fabric layer 8 can absorb the urine and prevent clumping. The urine passes through the non-woven fabric layer 8 and enters the diversion layer 7.

[0024] Then, the urine is absorbed again by the absorbent core 6. The absorbent cotton layer 5 can store urine and remove excess urine. The absorbent stick 404 can absorb the urine that cannot be stored in the absorbent surface layer 5 and store it inside the protrusion 403. The conical groove 401 can quickly absorb urine and at the same time reduce the possibility of the pants 2 absorbing urine and swelling and squeezing the baby's crotch and buttocks. Through the cooperation of the protrusion 403 and the absorbent stick 404, some urine can be stored. When the baby is sleeping and rolling around, it can reduce the leakage of urine and prevent the sheets from getting wet.

[0025] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
