Description

Technical Field

[0001] This utility model relates to the field of absorbent hygiene products technology, specifically to a leak-proof diaper with a side-absorption structure. Background Technology

[0002] When babies use diapers, they are very active and will urinate in various positions. Urine often does not come into contact with the center of the diaper surface, causing it to flow to the sides. Therefore, diapers usually have side vents to prevent urine from flowing laterally and leaking out of the diaper from the baby's leg area. However, urine tends to concentrate on one side of the absorbent core. The absorbent material on that side of the core becomes saturated and its absorption efficiency decreases, causing urine to remain on the surface for too long. The diaper lacks a structure inside that can efficiently absorb urine concentrated on one side.

[0003] Based on the above, Chinese Patent Publication No. CN210812022U discloses a leak-proof diaper, including a pant piece, a front waist support, and a back waist support. The front waist support includes an elastic front waist piece and two sets of symmetrical adhesive edges I on both sides of the front waist piece. The back waist support includes an elastic back waist piece and two sets of symmetrical adhesive edges II on both sides of the elastic back waist piece. Adhesive edges I include inner and outer adhesive edges in two layers. The inner surface of the inner adhesive edge is provided with several sets of female buckles, and the inner surface of the outer adhesive edge is provided with an adhesive layer. Adhesive edges II include a clamping edge, and one side of the clamping edge is provided with several sets of female buckles that match the female buckles. The sides of the pant piece are provided with two sets of symmetrical loops and two sets of symmetrical connecting straps. The end surface of the connecting straps is provided with an adhesive layer. The middle of the pant piece is provided with side elastic fabric.

[0004] The aforementioned patent document discloses a diaper that improves the fit of the waist and leg openings to the human body. This diaper uses elastic side panels that can be stretched to adjust the length on both sides to partially shrink the middle of the diaper. At the same time, the soft elastic side panels can better fit the baby's buttocks and effectively prevent urine leakage from the leg openings. However, the elastic side panels only block urine to prevent leakage outside the diaper. Urine still needs to be absorbed by the absorbent core. Since the urine blocked by the elastic side panels will concentrate on one side of the diaper, the absorbent core is prone to local saturation, which reduces the efficiency of urine absorption. This causes urine to remain on the surface for a long time, keeping the baby's skin in a moist state for a long time and making the baby prone to skin health problems. Therefore, this diaper still has room for improvement. Utility Model Content

[0005] To address the technical deficiencies in the background art, this utility model proposes a leak-proof diaper with a side-absorption structure, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0006] A leak-proof diaper with a side-absorption structure includes a top layer fabric, an absorbent core, and a leak-proof bottom film arranged sequentially from top to bottom. The top layer fabric has leak-proof partitions extending upward on both sides in the lateral direction. The leak-proof partitions are composed of an inner partition fabric and an outer partition fabric. A longitudinally extending partition elastic band is provided between the inner partition fabric and the outer partition fabric. The bottom of the inner partition fabric is fixedly connected to the lateral edge of the top layer fabric.

[0007] The two transverse ends of the leak-proof bottom film extend outward along the two transverse ends of the absorbent core and are folded upward to form an embedded end. The embedded end extends between the inner and outer partition fabrics. A side suction cavity is formed between the lower surface of the embedded end and the upper surface of the leak-proof bottom film. The side suction cavity is filled with a side suction layer.

[0008] As a further technical solution of this utility model, the surface of the inner partition cloth is provided with several guide holes, and a guide channel extending to the side suction cavity is formed between the inner partition cloth and the inner end.

[0009] As a further technical solution of this utility model, a diffusion cloth is provided between the absorbent core and the leak-proof bottom membrane.

[0010] As a further technical solution of this utility model, the lateral end of the diffusion cloth extends into the side suction cavity, the bottom of the inner partition cloth extends into the side suction cavity, and the lateral end of the diffusion cloth and the bottom of the inner partition cloth together wrap the side suction layer inside.

[0011] As a further technical solution of this utility model, the upper surface of the surface fabric is provided with a number of transversely extending flow guiding embossings, which extend to the position where the surface fabric and the inner partition fabric meet.

[0012] As a further technical solution of this utility model, the absorbent core is composed of an upper covering fabric, an upper absorbent layer, a fluffy cotton layer, a lower absorbent layer, and a lower covering fabric from top to bottom.

[0013] As a further technical solution of this utility model, the lower surface of the leak-proof bottom film is covered with a bottom layer fabric. The bottom layer fabric and the diffusion fabric extend outward from both ends in the longitudinal direction and together form the front waistband and the back waistband. The front waistband is provided with fixed waist stickers on both sides in the transverse direction, and the surface of the back waistband is provided with a waist sticker area that matches the fixed waist sticker.

[0014] The beneficial effects of this utility model are as follows:

[0015] In summary, this utility model discloses a diaper that improves both leak-proof and absorbent performance by enhancing the side absorption capacity. The leak-proof bottom film of the diaper is folded upwards to form an embedded end extending into the leak-proof sidewall, creating a barrier on both sides of the surface fabric that prevents urine from flowing laterally, thus achieving a leak-proof effect. When the leak-proof sidewall blocks the urine, the urine can penetrate through the inner sidewall fabric into the side absorption cavity and be absorbed by the side absorption layer. By having the side absorption layer and the absorbent core absorb the urine simultaneously, the diaper improves its urine absorption efficiency while preventing leaks. Attached Figure Description

Detailed Implementation

[0020] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0021] Reference Figure 1 , Figure 2 , Figure 3A leak-proof diaper with a side-absorption structure includes a top layer fabric 1, an absorbent core 2, and a leak-proof bottom film 3 arranged sequentially from top to bottom. The top layer fabric 1 has leak-proof partitions 4 extending upward on both sides in the lateral direction. The leak-proof partitions 4 are composed of an inner partition fabric 41 and an outer partition fabric 42. A longitudinally extending partition elastic band 43 is provided between the inner partition fabric 41 and the outer partition fabric 42. The bottom of the inner partition fabric 41 is fixedly connected to the lateral edge of the top layer fabric 1. The two ends of the leak-proof bottom film 3 extend outward along the two lateral edges of the absorbent core 2 and are folded upward to form an embedded end 31. The embedded end 31 extends between the inner partition fabric 41 and the outer partition fabric 42. A side-absorption cavity is formed between the lower surface of the embedded end 31 and the upper surface of the leak-proof bottom film 3. The side-absorption cavity is filled with a side-absorption layer 5.

[0022] This utility model discloses a diaper that improves side leakage prevention and absorption performance by enhancing side absorption capacity. The surface layer 1 is preferably a nonwoven fabric composed of hot-air nonwoven fabric and spunbond nonwoven fabric from top to bottom. The hot-air nonwoven fabric in the surface layer 1 is in direct contact with the human body, improving comfort. The spunbond nonwoven fabric in the surface layer 1 promotes urine penetration and diffusion and prevents urine from seeping back into the absorbent core 2 onto the surface layer 1, thus improving the dryness of the surface layer 1. The absorbent core 2 is composed of an upper covering fabric 21, an upper absorbent layer 22, a fluffy cotton layer 23, a lower absorbent layer 24, and a lower covering fabric 25 from top to bottom. The covering fabric 21 is preferably spunbond nonwoven fabric, used to promote the penetration and diffusion of urine and prevent urine backflow. The upper absorbent layer 22 and the lower absorbent layer 24 are preferably filled with absorbent materials such as absorbent resin, serving as the main urine-absorbing structure in the diaper. The fluffy cotton layer 23 is preferably a mesh structure layer made of fluffy cotton, which can improve the diffusion efficiency of urine inside the absorbent core 2. The lower covering fabric 25 is preferably dust-free paper, which can promote more even diffusion of urine that has penetrated to the bottom of the absorbent core 2. The leak-proof bottom film 3 is preferably a waterproof and breathable PE film, which can prevent urine inside the diaper from leaking to the outside and ensure the breathability of the diaper.

[0023] With the above structure, it should be further explained that the inner partition fabric 41 and the outer partition fabric 42 are integrally formed from spunbond nonwoven fabric. The leak-proof partition 4 is erected on the surface of the surface fabric 1 by the partition elastic 43 extending to the front waistband 8 and the back waistband 9 at both ends, thus forming two barriers on both sides of the surface fabric 1. The leak-proof bottom film 3 extends between the inner partition fabric 41 and the outer partition fabric 42 through the embedded end 31, so that the leak-proof partition 4 can block the urine flowing laterally on the surface of the surface fabric 1, thereby preventing urine leakage. When side leakage occurs, after the leak-proof partition 4 blocks the urine flowing laterally on the surface of the outer layer 1, some urine will gradually seep into the side absorption cavity along the inner partition 41. The side absorption layer 5 filled inside the side absorption cavity is preferably absorbent resin. The side absorption layer 5 and the absorbent core 2 absorb the urine simultaneously, so that the diaper can prevent side leakage while improving the absorption efficiency of urine, reducing the time that urine stays on the surface of the outer layer 1, which is conducive to improving the dryness of the surface of the outer layer 1 and avoiding health problems of the baby's skin.

[0024] As one of the preferred embodiments of this utility model, refer to Figure 1 The inner side panel 41 has several through-holes, and a flow channel 44 extending to the side suction cavity is formed between the inner side panel 41 and the inner end 31. The inner side panel 41 has several through-holes formed by a perforation process. The leak-proof side panel 4 prevents urine flowing laterally on the surface of the outer layer 1 from quickly penetrating into the flow channel 44 through the flow holes. The inner end 31 can prevent urine in the flow channel 44 from penetrating into the outer side panel 42, ensuring the dryness of the outside of the diaper. Urine can flow efficiently into the side suction cavity through the flow channel 44 and be absorbed by the side suction layer 5, improving the efficiency of urine absorption of the diaper.

[0025] As one of the preferred embodiments of this utility model, refer to Figure 1 A diffusion cloth 6 is provided between the absorbent core 2 and the leak-proof bottom membrane 3. The diffusion cloth 6 is preferably SMS non-woven fabric. The diffusion cloth 6 can further promote the diffusion of urine that has penetrated to the bottom of the absorbent core 2, increase the effective contact area between the urine and the absorbent core 2, and thus improve the efficiency of the absorbent core 2 in absorbing urine.

[0026] As one of the preferred embodiments of this utility model, refer to Figure 1The diffuser fabric 6 extends laterally into the side absorption cavity, and the bottom of the inner partition fabric 41 extends into the side absorption cavity. The diffuser fabric 6 and the bottom of the inner partition fabric 41 together wrap the side absorption layer 5. The diffuser fabric 6 and the inner partition fabric 41 wrap the side absorption layer 5 to constrain the absorbent material and prevent the side absorption layer 5 from clumping after absorbing urine. The inner partition fabric 41 can better guide the urine on the surface of the top layer fabric 1 to the side absorption layer 5 for absorption, while the diffuser fabric 6 can diffuse the urine at the bottom of the absorbent core 2 to the side absorption layer 5 for absorption. Even if the baby urinates in a normal position and the urine is not guided by the leak-proof partition 4, it can still be guided to the side absorption layer 5 by the diffuser fabric 6, avoiding waste of absorbent material inside the diaper.

[0027] As one of the preferred embodiments of this utility model, refer to Figure 2 The surface of the top layer fabric 1 has several horizontally extending flow-guiding embossing patterns 11. The flow-guiding embossing patterns 11 extend to the position where the top layer fabric 1 and the inner side panel fabric 41 meet. The surface of the top layer fabric 1 has several horizontally extending and downwardly recessed flow-guiding embossing patterns 11 formed by the embossing process. The flow-guiding embossing patterns 11 can promote the large-scale diffusion of urine along the surface of the top layer fabric 1. The urine diffused along the flow-guiding embossing patterns 11 can quickly penetrate into the side absorption cavity through the inner side panel fabric 41 and the flow-guiding channel 44 and be absorbed by the side absorption layer 5, thereby improving the efficiency of urine absorption of the diaper.

[0028] As one of the preferred embodiments of this utility model, refer to Figure 1 The lower surface of the leak-proof bottom film 3 is covered with a bottom layer fabric 7, which is preferably an SSS non-woven fabric. The bottom layer fabric 7 is located on the outside of the diaper, which can improve the softness and strength of the diaper surface. The bottom layer fabric 7 and the diffusion fabric 6 extend outward along both ends in the longitudinal direction and together form the front waistband 8 and the back waistband 9. The front waistband 8 has a fixing waist patch 81 on both sides in the transverse direction. The surface of the back waistband 9 has a waist patch area that matches the fixing waist patch 81. The front waistband 8 has several transversely extending elastic bands inside to improve the restraint of the diaper waistband. The fixing waist patch 81 and the waist patch area are preferably matching Velcro, so that the diaper can be better restrained and fixed to the user's waist through the waistband.

[0029] In summary, this utility model discloses a diaper that improves its side leakage prevention and absorption performance by enhancing the side absorption capacity. The leak-proof bottom film 3 at the bottom of the diaper is folded upward to form an embedded end 31 extending into the inside of the leak-proof partition 4. This creates a barrier on both sides of the surface fabric 1 that can prevent urine from continuing to flow laterally, thus achieving the side leakage prevention effect. When the leak-proof partition 4 blocks the urine, the urine can penetrate into the side absorption cavity through the inner partition fabric 41 and be absorbed by the side absorption layer 5. The side absorption layer 5 and the absorbent core 2 absorb the urine simultaneously, thus improving the urine absorption efficiency while preventing side leakage.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
