Description

Technical Field

[0001] This utility model relates to the field of diaper technology, specifically to a leak-proof diaper with three-dimensional mesh. Background Technology

[0002] Chinese Patent Publication No. CN209864313U discloses a baby diaper, including a diaper body. The diaper body includes an upper liquid-permeable surface layer, a lower liquid-impermeable layer, and an absorbent core disposed between the two. The liquid-permeable surface layer has anti-leakage layers on both longitudinal sides. The absorbent core has longitudinally spaced drainage grooves on its upper surface. The absorbent core has three parallel branches at its rear end. The free ends of the branches have holes symmetrical about the longitudinal axis of the body. The anti-leakage layers include a soft surface layer, an arc-shaped elastic band, and a water-repellent film covering the inner surface of the soft surface layer.

[0003] To prevent leakage of the anti-leakage layer, this utility model sets a water-repellent film on the inner side to achieve the anti-leakage effect. The film is designed with a different structure layer than the impermeable bottom layer. There are more structural layers on both sides of the absorbent body, and the structural layer after pressing is thicker. When worn, it comes into contact with the inner thigh, causing discomfort.

Each first vertical line is located above each of the horizontal lines, and each second vertical line is located below each of the horizontal lines. Each first vertical line is located between adjacent second vertical lines.

[0010] Furthermore, the diaper body has first tabs on both sides of the front waist area, and second tabs on both sides of the back waist area that cooperate with the first tabs.

[0011] Furthermore, the elastic strip is a rubber band.

[0012] Furthermore, the skin-friendly layer is meltblown nonwoven fabric.

[0013] Furthermore, the three-dimensional mesh is made of bamboo charcoal fiber.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model sets a three-dimensional mesh between the skin-friendly layer and the absorbent core. On the one hand, the skin-friendly layer can work with the three-dimensional mesh to achieve a flow guiding effect. On the other hand, the mesh structure of the three-dimensional mesh is used to separate the liquid clumps after the liquid passes through the skin-friendly layer. It has the function of blocking and isolating the flow whether the user is lying down or standing up, so as to achieve uniform and rapid absorption of liquid by the absorbent core.

[0016] 2. Through structural design, this utility model can also have the function of preventing side leakage by setting only a single layer of impermeable liquid bottom layer on both sides of the absorbent core. Attached Figure Description

[0030] The following will describe the implementation of this utility model in detail with reference to specific embodiments, so that the process of how this utility model uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Example

[0031] like Figures 1 to 3 As shown, a leak-proof diaper with a three-dimensional mesh includes a diaper body 1, the diaper body 1 includes an absorbent core 2, the absorbent core 2 has a liquid-impermeable bottom layer 3 at the bottom, the absorbent core 2 has a three-dimensional mesh 4 at the top, the three-dimensional mesh 4 is made of bamboo charcoal fiber, the three-dimensional mesh 4 has a skin-friendly layer 5 at the top, the skin-friendly layer 5 is meltblown nonwoven fabric, the skin-friendly layer 5 has soft side edges 6 on both sides, the soft side edges 6 are turned up on the inside, the two side edges of the skin-friendly layer 5 are turned up and form a leak-proof partition edge 7 with the soft side edges 6 from top to bottom, the soft side edges 6 include a front waist area 61, a middle area 62 and a back waist area 63 from top to bottom, the middle area 63 has an elastic strip 8, the elastic strip 8 is located between the soft side edges 6 and the skin-friendly layer 5, the elastic strip 8 is elastic band;

[0032] The skin-friendly layer 5 is provided with a first groove 51, which is located on both sides of the absorbent core 2. The liquid-impermeable bottom layer 3 is turned up on both sides of the first groove 51 and connected to the side of the skin-friendly layer 5.

[0033] The bottom of the impermeable bottom layer 3 is provided with a covering layer 9. The bottom of the skin-softening side 6 is connected to the top of the covering layer 9. The two skin-softening side 6 are provided with a second pressing groove 64. The two skin-softening side 6 are connected to the covering layer 9 at the second pressing groove 64. The outer side of the skin-softening side 6 and the outer side of the covering layer 9 can form a double-layer bubble edge, which is more comfortable when it fits the sides of the thigh.

[0034] By setting a three-dimensional mesh 4 between the skin-friendly layer 5 and the absorbent core 2, on the one hand, the skin-friendly layer 5 can work with the three-dimensional mesh 4 to achieve a flow guiding effect. On the other hand, the mesh structure of the three-dimensional mesh 4 is used to separate the liquid clumps after the liquid passes through the skin-friendly layer 5. It has the function of blocking and isolating the flow whether the user is lying down or standing up, so as to achieve uniform and rapid absorption of the liquid by the absorbent core 2.

[0035] Through structural design, a single layer of impermeable liquid bottom layer 3 is set on both sides of the absorbent core 2, which can also have the function of preventing side leakage.
