Description

Technical Field

[0001] The utility model relates to the technical field of disposable absorbent articles, and particularly relates to a daily-use side leakage-proof menstrual pants. Background Art

[0002] Menstrual pants are a type of pant-shaped sanitary napkin that prevent menstrual fluid from leaking out through a fully enclosed method. Menstrual pants can be used at night during sleep or during normal daytime use. For night-use menstrual pants, menstrual fluid mainly flows towards the tail of the first absorbent core, and the effective absorption area is large. For daily-use menstrual pants, menstrual fluid is concentrated and absorbed in the middle section of the first absorbent core, i.e., the crotch area, and the absorption capacity of the crotch area is limited. Therefore, daily-use menstrual pants are prone to side leakage in the crotch area.

[0003] To solve the above problems, the present case proposes a daily-use side leakage-proof menstrual pants. Content of the Utility Model

[0004] Therefore, in view of the above problems, the utility model proposes a daily-use side leakage-proof menstrual pants.

[0005] To solve the above technical problems, the solution adopted by the utility model is: a daily-use side leakage-proof menstrual pants, including a pant-shaped liquid-permeable surface layer and a pant-shaped liquid-impermeable bottom layer. An elastic wrapping layer is provided between the front waist and the rear waist of the pant-shaped liquid-permeable surface layer and the pant-shaped liquid-impermeable bottom layer. A first absorbent core is provided at the crotch between the pant-shaped liquid-permeable surface layer and the pant-shaped liquid-impermeable bottom layer. A second absorbent core is spliced at the rear end of the first absorbent core, and the second absorbent core is a water-absorbing paper layer;

[0006] The first absorbent core includes a first absorbent body and a second absorbent body. An opening is formed through the middle of the first absorbent body, and the second absorbent body is disposed within the opening. The two sides of the first absorbent body are folded upwards to form folding parts, the folding parts are higher than the second absorbent body, and a diversion groove is formed between the folding parts with the upper surface of the second absorbent body as the bottom;

[0007] The absorption capacity of the second absorbent body is greater than that of the first absorbent body. A wrinkled area that can be unfolded downward to adapt to the expansion of the second absorbent body is provided on the pant-shaped liquid-impermeable bottom layer at the position of the first absorbent core.

[0008] Further improvement is: the first absorbent body is a fluff pulp and superabsorbent polymer absorbent body.

[0009] Further improvement is: the second absorbent body includes water-absorbing paper and a superabsorbent polymer particle layer, the superabsorbent polymer particle layer is adhesively disposed on the upper surface of the water-absorbing paper, and the two sides of the water-absorbing paper are folded downward to completely cover the superabsorbent polymer particle layer.

[0010] Further improvement: Inner leakage-proof side edges are respectively arranged on both sides of the crotch of the pant-shaped liquid-permeable surface layer and the pant-shaped liquid-impermeable bottom layer. The outer sides of the inner leakage-proof side edges are glued between the pant-shaped liquid-permeable surface layer and the pant-shaped liquid-impermeable bottom layer, and the inner sides are glued to the pant-shaped liquid-permeable surface layer.

[0011] Further improvement: Outer leakage-proof side edges are formed by extending outward from both sides of the crotch of the pant-shaped liquid-impermeable bottom layer.

[0012] Further improvement: A rubber band for tightening front and back to make the crotch fit the skin is arranged along the crotch between the outer side of the inner leakage-proof side edge and the pant-shaped liquid-impermeable bottom layer.

[0013] Further improvement: The inner leakage-proof side edge is composed of an inner PE film layer and an outer water-repellent non-woven fabric layer.

[0014] Further improvement: The elastic wrapping layer is uniformly composed of a number of rubber bands in a straight line or continuous wavy shape.

[0015] Further improvement: The pant-shaped liquid-permeable surface layer is a hydrophilic non-woven fabric layer.

[0016] Further improvement: The pant-shaped liquid-impermeable bottom layer is a water-repellent non-woven fabric layer.

[0017] By adopting the foregoing technical solutions, the beneficial effects of the present utility model are as follows:

[0018] The menstrual pants in this case are daily-use menstrual pants. By increasing the absorption capacity of the crotch, that is, increasing the water absorption capacity of the first absorbent core, side leakage at the crotch is avoided. At the same time, by reducing the absorption capacity of the tail, that is, reducing the absorption capacity of the second absorbent core, waste of absorbent materials is avoided.

[0019] The first absorbent core is composed of a first absorbent body and a second absorbent body. The second absorbent body is arranged inside the first absorbent body to first receive and absorb menstrual fluid. Both sides of the first absorbent core are turned up to form a diversion groove. The diversion groove gathers the menstrual fluid in the diversion groove, increases the menstrual fluid absorption capacity of the second absorbent body, reduces the menstrual fluid absorption capacity of the first absorbent body, and avoids side leakage at the crotch.

[0020] The wrinkled area arranged at the crotch of the pant-shaped liquid-impermeable bottom layer can adapt to the expansion of the second absorbent body and bulge downward to keep the surface layer flat.

[0021] Further beneficial effects are: The first absorbent body is made of a mixture of fluff pulp and superabsorbent polymer particles. The second absorbent body is made of absorbent paper wrapped downward around a superabsorbent polymer particle layer. The liquid absorption speed of the second absorbent body is greater than that of the first absorbent body, and the second absorbent body is located in the middle of the first absorbent body, effectively avoiding side leakage at the crotch of the menstrual pants.

[0022] On both sides of the absorbent paper in the second absorber, it is folded downwards to wrap the high-molecular water-absorbing particle layer, so that after the high-molecular water-absorbing particles absorb liquid and expand, the wrinkled area can expand downwards better, keeping the surface layer flat.

[0023] A further beneficial effect is that in this case, inner anti-side leakage partitions and outer anti-side leakage partitions are provided on both sides of the crotch, and the side leakage is further prevented through the structure of the double partitions. The inner and outer sides of the inner anti-side leakage partition are glued and fixed, and the middle is in a fluffy state, with little friction against the inner thigh.

[0024] A further beneficial effect is that a rubber band is provided between the outer side of the inner anti-side leakage partition and the liquid-impermeable bottom layer of the panty-shaped, which restricts the movement of the crotch, further avoids side leakage, and at the same time can counteract the gravity of the first absorption core to keep the crotch always close to the skin, effectively avoiding side leakage.
