Description

Technical Field

[0001] The utility model relates to the field of disposable sanitary products, in particular to a novel side leakage-proof baby diaper. Background Art

[0002] The conventional structure of diapers on the market now is: a surface non-woven fabric, a waterproof film at the bottom, a composite core at the center of the diaper, and an elastic waist at one or both ends of the diaper. The surface non-woven fabric is a hydrophilic layer, the waterproof film is an anti-penetration layer, the composite core in the middle is a composite structure composed of absorbent materials, and Velcro ear straps are set on both sides of the elastic waist for fixation.

[0003] Under this traditional structure, the elasticity, breathability and softness of the elastic waist greatly affect the comfort of wearing diapers, but this component cannot be omitted under the premise of ensuring leak-proofness. Utility Model Content

[0004] Therefore, the utility model provides a new side leakage-proof baby diaper, which solves the problem that the leakage-proof effect and comfort of the existing diapers cannot be taken into account at the same time.

[0005] In order to achieve the above object, the utility model is realized by the following technical solutions:

[0006] A novel side leakage prevention baby diaper comprises a stacked surface non-woven fabric, an absorbent core and a water-repellent bottom layer, wherein the diaper has a longitudinal length direction and a transverse width direction, and the surface non-woven fabric on both sides of the absorbent core is provided with symmetrically distributed three-dimensional guards, the three-dimensional guards comprising an elastic end containing an elastic member located above the absorbent core and a folded end that wraps around the elastic member and extends to both transverse sides, the folded end is covered with a side non-woven fabric and bonded to the surface of the surface non-woven fabric, a side elastic waistband is applied to the upper surface of the side non-woven fabrics located at the longitudinal ends of the diaper, and a connected / non-connected central elastic waistband is provided between the two side elastic waistbands.

[0007] Preferably, the central elastic waist is not joined to the side elastic waists on both sides, and the distance between the two gradually decreases from the longitudinal end of the diaper inward.

[0008] Preferably, both longitudinal ends of the diaper are provided with side elastic waistbands and a central elastic waistband.

[0009] Preferably, both longitudinal ends of the diaper are provided with folded non-woven fabrics for folding the longitudinal end portions.

[0010] Preferably, the distance between the central elastic waist and the longitudinal ends of the diaper is 5-25 mm.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are:

[0012] The technical solution is to split the traditional whole elastic waistband and arrange them in different positions according to different positions. The side elastic waistbands on both sides are independent of the central elastic waistband to form different contraction ranges. The side elastic waistbands on both sides are curled up after contraction, and form a coverage angle of not less than 270 degrees with the central elastic waistband, forming a pocket-like structure located at the longitudinal end of the diaper, which has a certain function of preventing front and back leakage. At the same time, the split elastic waistband can also form a breathable space in the thickness direction, thereby improving the breathability of the waistband to a certain extent; and the side elastic waistbands on both sides are arranged at the bonding positions at the longitudinal ends of the three-dimensional guardrail, which is equivalent to adding a layer of fixed structure at the longitudinal ends of the two three-dimensional guardrails, thereby ensuring the structural stability of the three-dimensional guardrail, increasing the structural strength, and preventing the occurrence of side leakage.

[0018] The following will describe the implementation methods of the present invention in detail in conjunction with specific embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0019] Embodiment 1

[0020] refer to Figure 1 and Figure 2A novel side leakage prevention baby diaper, comprising a stacked surface non-woven fabric 1, an absorbent core 2 and a water-repellent bottom layer 3, the diaper is defined as having a longitudinal direction in the length direction and a transverse direction in the width direction, and the surface non-woven fabric 1 located on both sides of the absorbent core 2 is provided with symmetrically distributed three-dimensional guards 4, the three-dimensional guards 4 comprising an elastic end 41 containing an elastic member located above the absorbent core 2 and a folded end 42 that wraps around the elastic member and extends to both sides in the transverse direction, the folded end 42 is covered with a side non-woven fabric 5 and bonded to the surface of the surface non-woven fabric 1, and is located on both sides of the longitudinal direction of the diaper A side elastic waist 6 is applied to the upper surface of the side non-woven fabric 5 at the end, and a connected / non-connected center elastic waist 7 is provided between the two side elastic waist circumferences 6; connected / non-connected here refers to whether there is an overlapping part of the front projection between the side elastic waist circumference 6 and the center elastic waist circumference 7, and the actual elastic force range formed between the two is different due to the different applied stacking positions. The center elastic waist circumference 7 is closer to the absorbent core 2, and the two side elastic waist circumferences 6 are closer to the clothing layer in contact with the human body, thereby forming different elastic force ranges in the thickness direction of the diaper. The technical solution is to split the traditional whole elastic waistband and arrange them in different positions according to different positions. The side elastic waistbands 6 and the central elastic waistband 7 on both sides are independent of each other, forming different contraction intervals. The side elastic waistbands 6 on both sides are curled up after contraction, and form a coverage angle of not less than 270 degrees with the central elastic waistband 7, forming a pocket-like structure located at the longitudinal end of the diaper, which has a certain function of preventing front and back leakage. At the same time, the split elastic waistband can also form a breathable space in the thickness direction, thereby improving the breathability of the waistband to a certain extent; and the side elastic waistbands 6 on both sides are arranged at the bonding positions at the longitudinal ends of the three-dimensional guard 4, which is equivalent to adding a layer of fixed structure at the longitudinal ends of the two three-dimensional guards 4, thereby ensuring the structural stability of the three-dimensional guard 4, increasing the structural strength, and preventing the occurrence of side leakage.

[0021] In addition, the diaper may be provided with side elastic waistbands 6 and center elastic waistbands 7 at both longitudinal ends. This structure increases the structural strength of both longitudinal ends of the three-dimensional guard 4, further prevents the three-dimensional guard 4 from warping, and forms a complete front and rear leakage pocket in the diaper, which can effectively solve the problem of side leakage of ordinary diapers during use, ensures the water-locking effect, and further enables the wearer to feel comfortable, thereby improving the leakage-proof performance of the diaper.

[0022] Embodiment 2

[0023] refer to Figure 3Compared with the first embodiment, the central elastic waist circumference 7 is not connected to the side elastic waist circumferences 6 on both sides, and the distance between the two gradually decreases from the longitudinal end of the diaper to the inside. Under this structure, there is a certain uncovered surface a between the orthographic projection surface of the central elastic waist circumference 7 and the side elastic waist circumferences 6 on both sides, and this uncovered surface a gradually decreases from the longitudinal ends of the diaper to the inside, so that the waist circumference at the longitudinal ends of the diaper can form a part without elasticity and without wrinkles to reduce the decrease in comfort caused by wrinkles, and also form a height difference with the wrinkled part. This height difference can form a breathable structure while ensuring the elasticity of the waist circumference to improve the breathability.

[0024] Furthermore, the longitudinal ends of the diaper are provided with folded nonwoven fabrics 8 for folding the longitudinal ends. The folded nonwoven fabrics 8 can increase the thickness of the longitudinal ends to improve the softness there and further improve the comfort of the folded positions of the ends.

[0025] Embodiment 3

[0026] refer to Figure 4 Compared with the first embodiment, the distance d between the central elastic waist 7 and the longitudinal ends of the diaper is 5-25 mm. That is, the main elastic force range of the central elastic waist 7 located at the center is farther away from the longitudinal ends of the diaper, thereby further reducing the deformation of the longitudinal ends of the diaper, and the deformation transition from the central elastic waist 7 to the longitudinal ends is smooth, and the appearance is more beautiful.

[0027] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
