Description

Technical Field

[0001] This utility model relates to the field of disposable hygiene products, and in particular to a baby diaper with a core featuring a uniquely shaped groove. Background Technology

[0002] The structure of existing disposable diapers is generally as follows: from top to bottom, they include a liquid-permeable top layer, an absorbent core layer, and a liquid-impermeable bottom layer. The absorbent core layer is made of a combination of loose non-woven fabric and superabsorbent polymer (SAP), or a mixture of wood pulp fiber and SAP wrapped in non-woven fabric, forming a block structure used to absorb and retain human excrement. The liquid-permeable top layer consists of hydrophilic non-woven fabric and hydrophobic non-woven fabric fixed to both sides of the hydrophilic non-woven fabric. The hydrophilic non-woven fabric adheres to the upper surface of the absorbent core layer and is bent downwards to cover the two sides of the absorbent core layer, and is in contact with the absorbent core layer. The absorbent core layer adheres to the liquid-impermeable bottom layer, providing a comfortable and dry feel when in contact with the body, while allowing liquid to pass freely into the lower absorbent core layer. The liquid-impermeable bottom layer is composed of a breathable, water-impermeable membrane and a hydrophobic nonwoven fabric composite, used to retain absorbed liquid within the absorbent core layer, thus preventing the absorbed liquid from staining the wearer's pants. Elastic bands are provided in the back waistband area, giving the back waistband area lateral elasticity. Ear loops are also provided on both sides of the back waistband area for fitting with the front waistband area, enabling the diaper to be worn.

[0003] When babies use diapers, they often use them frequently in small amounts. To avoid waste, the frequency of diaper changes is reduced and the wearing time is increased. In addition, the absorbent core is a single-piece structure. When the absorbent capacity is increased, the thickness of the absorbent core increases accordingly. At the same time, for male infants, wearing diapers can put pressure on the genitals, resulting in poor breathability and easy bacterial growth. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model provides a baby diaper with a core having a special groove, which mainly solves the problem that when male infants use baby diapers, it will cause pressure on the genitals, resulting in poor breathability and easy growth of bacteria.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a baby diaper with a core featuring irregularly shaped grooves, comprising a diaper body, the diaper body comprising, from top to bottom, a liquid-permeable surface layer, a first absorbent core, and a liquid-impermeable bottom layer, wherein the upper surface of the first absorbent core has a groove located at the genital area of ​​the human body, and a second absorbent core is disposed within the groove, the thickness of the second absorbent core being less than the thickness of the first absorbent core, a plurality of V-shaped grooves are longitudinally arranged on the upper surface of the second absorbent core, an inverted trapezoidal protrusion is formed between two of the V-shaped grooves, and a through hole is horizontally arranged on each of the trapezoidal protrusions, wherein a superabsorbent polymer is disposed within the through hole, and an elastic band is disposed on the lower surface of the second absorbent core.

[0006] Furthermore, a long groove is longitudinally provided in the middle of the first absorbent core.

[0007] Furthermore, a flow guiding layer is provided on the upper surface of the second absorbent core, located below the liquid-permeable surface layer.

[0008] Furthermore, a raised ring is provided on the upper part of the sidewall of the groove, the second absorbent core is configured in a stepped shape, and the lower part of the second absorbent core abuts against the space formed by the groove and the raised ring.

[0009] Furthermore, a plurality of raised strips are provided laterally on the lower surface of the second absorbent core.

[0010] Furthermore, the second absorbent core is provided with a plurality of vent holes.

[0011] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: This baby diaper with a uniquely shaped groove in the core, by setting a second absorbent core within the groove of the first absorbent core, and the thickness of the second absorbent core being less than that of the first absorbent core, allows the user's genitals to rest on the second absorbent core during use, preventing the diaper from compressing the genitals and causing poor breathability and bacterial growth. The V-shaped groove on the upper surface of the second absorbent core reduces contact between the diaper body and the user's skin, increasing breathability. The trapezoidal protrusions are horizontally arranged with through-holes containing superabsorbent polymer resin, increasing the absorbency of the second absorbent core and keeping the liquid-permeable surface in contact with the skin dry. An elastic band is provided on the lower surface of the second absorbent core, making it contractible and improving its absorbency. Furthermore, a long groove is longitudinally provided in the middle of the first absorbent core, facilitating folding of the diaper body and allowing for user movement during use. Additionally, a guide layer facilitates liquid diffusion. Furthermore, the lower part of the second absorbent core rests against the space formed by the groove and the raised ring, allowing liquid to permeate downwards from the second absorbent core and then diffuse through contact with the first absorbent core, promoting even distribution of liquid across the diaper body and increasing its absorbency and comfort. Finally, multiple ventilation holes are provided on the second absorbent core to increase its breathability and enhance comfort. Attached Figure Description
