Technical Field
[0001] The utility model relates to the technical field of baby diapers, in particular to a highly absorbent pull-up diaper. Background Art
[0002] Pull-up diapers are made of superabsorbent resin (abbreviation: polymer SAP) materials. Among them, superabsorbent resin (abbreviation: polymer SAP) is mainly made of starch and acrylate. Its outstanding feature is that its water absorption and water storage capacity are astonishingly large. Pull-up diapers made of superabsorbent resin are commonly known as "diapers" and are usually used as daily necessities for babies. A dry diaper can keep a baby sleeping soundly all night. The superabsorbent resin used to make pull-up diapers has strong water absorption. However, since the pull-up diapers made are relatively thin and light for the comfort of babies, and the thickness of the pull-up diapers is limited. During the baby's whole-night sleep, when the baby urinates a large amount or forgets to change the pull-up diaper, after the superabsorbent resin absorbs too much urine, it will overflow. Its water absorption space is limited and cannot store too much urine volume. Summary of the Invention
[0003] The utility model provides a highly absorbent pull-up diaper, which overcomes the deficiencies described in the background art.
[0004] The technical solution adopted by the utility model to solve its technical problems is as follows:
[0005] A highly absorbent pull-up diaper includes elastic leg cuffs, an elastic waistband, a core body, and a bottom pocket. The elastic waistband is arranged at the upper end of the bottom pocket. When a baby wears it, the elastic waistband is sleeved on the baby's waist, so that the baby's feet extend out from the elastic leg cuffs on both left and right sides of the bottom pocket, and the elastic leg cuffs wrap the baby's thighs. Two core bodies are arranged in the front and rear parts of the bottom pocket;
[0006] The core body is provided with a telescopic structure, a barrier layer, a first water-absorbing plate, and a pocket cloth. The telescopic structure is arranged outside the pocket cloth. The first water-absorbing plate is adhered to the outside of the barrier layer. The barrier layer is located outside the pocket cloth, and the telescopic structure passes through the inside of the barrier layer. When the baby's urine flows out and contacts the pocket cloth, the urine seeps into the barrier layer from the pocket cloth and is absorbed by the first water-absorbing plate, and the urine is adsorbed to the outer layer through the telescopic structure.
[0007] A preferred technical solution: the telescopic structure is provided with a compression plate, an expansion structure, a pleated membrane, a connecting block, and a first water-absorbing block. The pleated membrane is arranged on the inner side of the expansion structure, the compression plate is arranged on the inner side of the expansion structure, the compression plate is sewn and connected to the connecting block, the density of the connecting block is greater than the density of the first water-absorbing block, when urine penetrates into the first water-absorbing block from the shawl cloth, the urine penetrates from the first water-absorbing block into the connecting block, the connecting block is arranged on the outside of the first water-absorbing block, the first water-absorbing block is arranged on the outside of the shawl cloth through a barrier layer, the barrier layer is made of polypropylene, and after the barrier layer discharges the urine that penetrates the shawl cloth, the urine is locked to the outside of the barrier layer.
[0008] A preferred technical solution: the expansion structure is provided with a urine-indicating membrane, an outer layer of cloth, a soft elastic block, and a second water-absorbent plate. The compression plate is arranged on the inner side of the urine-indicating membrane. The soft elastic block connects the outer layer of cloth and the urine-indicating membrane. The soft elastic block is in a "Z"-shaped column shape and is distributed in an array on the side of the second water-absorbent plate. When the two sides of the soft elastic block are stretched outward, they are in a straight line state and have inward elasticity. When the second water-absorbent plate absorbs urine that has penetrated into the urine-indicating membrane and the first water-absorbent plate, it expands and drives the soft elastic block to be expanded by the outer layer of cloth and the urine-indicating membrane under the expansion of the second water-absorbent plate and open. The soft elastic block generates inward elasticity to squeeze the compression plate and the pleated membrane, and after the compression plate expands, it is continuously pressed inward by the elasticity of the soft elastic block and causes the urine to fall into the second water-absorbent plate.
[0009] A preferred technical solution: The second water-absorbent plate has a large density. Under the compression of the outer cloth and the urine-indicating film, the second water-absorbent plate forms a certain compression elasticity. When the outer cloth and the urine-indicating film absorb urine, it penetrates into the second water-absorbent plate to expand it and open the soft elastic blocks. The outer cloth and the urine-indicating film open to expand the space under the expansion of the second water-absorbent plate, and then the second water-absorbent plate absorbs the urine dropped from the compression plate.
[0010] A preferred technical solution: The widths of the outer layer of cloth and the urine-indicating film gradually decrease toward the upper and lower sides until they overlap with each other, and the points where the outer layer of cloth and the urine-indicating film overlap are connected and fixed to the inner side of the bottom pocket.
[0011] A better technical solution: the compression plate is provided with absorbent balls, a hollow plate, and a second absorbent block. The absorbent balls are made of a polymer absorbent resin material with a density greater than that of the second absorbent block, and the density of the absorbent balls is greater than that of the second absorbent block. The absorbent balls are arranged equidistantly inside, and the hollow plate is arranged on the side of the second absorbent block. When the hollow plate is arranged on the side of the connecting block, urine is absorbed and conducted to the absorbent balls through the second absorbent block, causing the absorbent balls to expand and push up the pleated membrane outward.
[0012] A better technical solution: the first water-absorbing block and the compression plate and the connecting block are located at the same axial position, and the expansion structure absorbs urine that penetrates into the connecting block and transmits it to the water-absorbing balls in the compression plate, so that the multiple water-absorbing balls arranged equidistantly expand after absorption, and the water-absorbing balls expand outward.
[0013] A preferred technical solution: The densities of the first water-absorbing block, the connecting block, and the compression plate decrease in sequence, and their water absorption capacities increase in sequence. Moreover, the water-absorbing balls in the compression plate have a higher density than the second water-absorbing block. The first water-absorbing block, the connecting block, and the compression plate are all made of high-molecular water-absorbing resin materials, and the smaller the density, the stronger the water absorption capacity.
[0014] A preferred technical solution: The first water-absorbing plate is made of high-molecular water-absorbing resin material and has water absorption capacity. The pocket cloth is made of non-woven fabric material and has good air permeability, which is suitable for the practical use of infants.
[0015] Compared with the prior art, this technical solution has the following advantages:
[0016] In the present utility model, after the infant puts on the bottom pocket, the feet extend out from the elastic leg circumference and are fixed to the infant's waist through the elastic waist circumference. When the infant lies down, urine will flow forward and backward, and penetrate into the pocket cloth in the core body. Through the single-way drainage property of the barrier layer, the urine passes through the barrier layer and is absorbed by the first water-absorbing plate. Moreover, after the urine passes through the pocket cloth and is continuously absorbed in the telescopic structure, it will expand, increasing the space at the telescopic structure position to improve the overall water absorption capacity.
[0017] In the present utility model, the infant's urine penetrates into the barrier layer from the pocket cloth, and the urine also penetrates outward at the telescopic structure position. Since the densities of the first water-absorbing block, the connecting block, and the compression plate in the present utility model decrease in sequence, the water absorption capacity of the outermost compression plate with the smallest density is the strongest. Therefore, the urine that penetrates into the first water-absorbing block will be absorbed by the external connecting block. The urine is absorbed by the water-absorbing balls in the compression plate through the hollow plate connected by the connecting block, and the water-absorbing balls expand to lift the wrinkled film. After lifting the wrinkled film, it drives the urine display film and the outer layer cloth to expand each other, increasing the space and improving the overall water absorption capacity.

Detailed implementation mode
[0025] As Figures 1 to 5 shown, a highly water-absorbent pull-up diaper is proposed in the present utility model, which includes an elastic leg circumference 1, an elastic waist circumference 2, a core body 3, and a bottom pocket 4. The elastic waist circumference 2 is arranged at the upper end of the bottom pocket 4. When a baby wears it, the elastic waist circumference 2 is sleeved on the baby's waist, enabling the baby's feet to extend from the elastic leg circumferences 1 on the left and right sides of the bottom pocket 4, and the elastic leg circumferences 1 wrap around the baby's thighs. Two core bodies 3 are arranged in the front and rear parts of the bottom pocket 4.
[0026] The core body 3 is provided with a telescopic structure 31, a barrier layer 32, a first water absorption plate 33, and a pocket cloth 34. The telescopic structure 31 is arranged outside the pocket cloth 34. The first water absorption plate 33 is adhered to the outside of the barrier layer 32. The barrier layer 32 is located outside the pocket cloth 34, and the telescopic structure 31 passes through the inside of the barrier layer 32. When the baby's urine flows out and contacts the pocket cloth 34, the urine seeps into the barrier layer 32 from the pocket cloth 34 and is absorbed by the first water absorption plate 33. Moreover, the urine is adsorbed to the outer layer through the telescopic structure 31.
[0027] In the present utility model, after the baby puts on the bottom pocket 4, the feet extend from the elastic leg circumferences 1 and are fixed to the baby's waist through the elastic waist circumference 2. When the baby lies down, the urine will flow to the front and back sides and seep into the pocket cloth 34 in the core body 3. Due to the one-way drainage property of the barrier layer 32, the urine passes through the barrier layer 32 and is absorbed by the first water absorption plate 33. And after the urine passes through the pocket cloth 34 and is continuously absorbed in the telescopic structure 31, it will expand, increasing the space at the telescopic structure 31 position to improve the overall water absorption.
[0028] Among them, the telescopic structure 31 is provided with a compression plate 311, an expansion structure 312, a corrugated film 313, a connecting block 314, and a first water-absorbing block 315. The corrugated film 313 is arranged inside the expansion structure 312, and the compression plate 311 is arranged inside the expansion structure 312. The compression plate 311 is stitched and connected to the connecting block 314. The density of the connecting block 314 is greater than that of the first water-absorbing block 315. When urine seeps into the first water-absorbing block 315 from the pocket cloth 34, the urine penetrates from the first water-absorbing block 315 into the connecting block 314. The connecting block 314 is arranged outside the first water-absorbing block 315. The first water-absorbing block 315 passes through the barrier layer 32 and is arranged outside the pocket cloth 34. The barrier layer 32 is made of polypropylene. After the urine penetrating through the pocket cloth 34 is discharged, the urine is locked outside the barrier layer 32.
[0029] Among them, the expansion structure 312 is provided with a urine display film 3121, an outer layer cloth 3122, a soft elastic block 3123, and a second water-absorbing plate 3124. The compression plate 311 is arranged inside the urine display film 3121. The soft elastic block 3123 connects the outer layer cloth 3122 and the urine display film 3121. The soft elastic block 3123 is in the shape of a "Z"-shaped column and is distributed in an array on the side of the second water-absorbing plate 3124. When the two sides of the soft elastic block 3123 are stretched outwards, they are in a straight state and have an inward elasticity. When the second water-absorbing plate 3124 absorbs the urine that has penetrated into the urine display film 3121 and the first water-absorbing plate 33 and expands, it drives the soft elastic block 3123 to be expanded by the outer layer cloth 3122 and the urine display film 3121 under the expansion of the second water-absorbing plate 3124 and open. The inward elasticity generated by the soft elastic block 3123 squeezes the compression plate 311 and the corrugated film 313, and after the compression plate 311 expands, it is continuously pressed inward by the elasticity of the soft elastic block 3123 and the urine drops into the second water-absorbing plate 3124.
[0030] Among them, the widths of the outer layer cloth 3122 and the urine display film 3121 gradually decrease towards the upper and lower sides until they overlap, and the overlapping points of the outer layer cloth 3122 and the urine display film 3121 are fixedly connected to the inside of the bottom pocket 4.
[0031] Among them, the second water-absorbing plate 3124 has a high density. Under the compression of the outer layer cloth 3122 and the urine display film 3121, the second water-absorbing plate 3124 forms a certain compression elasticity. When the outer layer cloth 3122 and the urine display film 3121 absorb urine and penetrate into the second water-absorbing plate 3124, it causes the second water-absorbing plate 3124 to expand and the soft elastic block 3123 to open, and the outer layer cloth 3122 and the urine display film 3121 open to expand the space under the expansion of the second water-absorbing plate 3124. Furthermore, the second water-absorbing plate 3124 absorbs the urine dropped from the compression plate 311.
[0032] Among them, the compression plate 311 is provided with water-absorbing balls 3111, a hollow plate 3112, and a second water-absorbing block 3113. The water-absorbing balls 3111 are made of a high-molecular water-absorbing resin material with a density greater than that of the second water-absorbing block 3113, and the density of the water-absorbing balls 3111 is greater than that of the second water-absorbing block 3113. The water-absorbing balls 3111 are equidistantly arranged inside 3114, and the hollow plate 3112 is arranged on the side of the second water-absorbing block 3113. When the hollow plate 3112 is arranged on the side of the connecting block 314 to absorb urine, it is conducted to the water-absorbing balls 3111 through the second water-absorbing block 3113, and the water-absorbing balls 3111 are expanded and push the pleated membrane 313 outward.
[0033] The first water-absorbing block 315, the compression plate 311 and the connecting block 314 are located at the same axial position, and the expansion structure 312 absorbs urine that penetrates into the connecting block 314 and transmits it to the water-absorbing balls 3111 in the compression plate 311, so that the multiple water-absorbing balls 3111 arranged equidistantly absorb and expand, and the water-absorbing balls 3111 expand outward.
[0034] Among them, the densities of the first water absorbent block 315, the connecting block 314 and the compression plate 311 decrease successively, and their water absorption also increases successively. The first water absorbent block 315, the connecting block 314 and the compression plate 311 are all made of high molecular water absorbent resin materials, and the smaller the density, the stronger the water absorption.
[0035] The first water-absorbing plate 33 is made of a polymer water-absorbing resin material and has water absorption, and the pocket cloth 34 is made of a non-woven fabric material and has good air permeability and is suitable for babies.
[0036] In the utility model, the baby's urine penetrates into the barrier layer 32 from the bag cloth 34, and the urine penetrates outward at the position of the telescopic structure 31. Since the densities of the first water-absorbing block 315, the connecting block 314 and the compression plate 311 in the utility model decrease in sequence, the outermost compression plate 311 has a higher density and a stronger water absorption, and the urine that penetrates into the first water-absorbing block 315 will be absorbed by the external connecting block 314, and the urine is absorbed by the water-absorbing balls 3111 in the compression plate 311 through the hollow plate 3112 connected to the connecting block 314, and the water-absorbing balls 3111 expand to lift up the pleated membrane 313. The utility model mainly utilizes the different densities of the compression plate 311, the connecting block 314 and the first water-absorbing block 315 in the telescopic structure 31 to produce different urine absorption The performance of the liquid causes urine to flow to the outer layer, and causes urine to expand and expand the space in the outer compression plate 311, wherein the density of the water-absorbing ball 3111 in the compression plate 311 is greater than that of the second water-absorbing block 3113. After absorbing urine, the water-absorbing ball 3111 will expand and drive the entire compression plate 311 to expand. The expansion of the compression plate 311 drives the connected expansion structure 312 to expand, and under the elasticity of the soft elastic block 3123, the compression plate 311 is elastically pressed in the reverse direction. The compression plate 311 is pressed and urine flows out to the second water-absorbing plate 3124 for uniform absorption. When the urine becomes larger and larger, the compression plate 311 continues to push up the pleated membrane 313 outward and expand it, so that the outer cloth 3122 and the urine-displaying membrane 3121 continue to expand the space to achieve the effect of increasing the amount of urine absorbed.
[0037] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope covered by the present invention.
