[0004] Therefore, in view of the above problems, the utility model provides a degradable absorbent article to solve the problem that the existing disposable absorbent articles take a long time to degrade.

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

[0006] A degradable absorbent article comprises an absorbent body, wherein the absorbent body comprises an outer casing and an absorbent sheet, wherein the absorbent sheet is arranged in the outer casing, wherein the absorbent sheet comprises a liquid-permeable surface layer, a liquid-impermeable bottom layer and an absorbent core between the liquid-permeable surface layer and the liquid-impermeable bottom layer, wherein an oxidizing decomposition agent is attached to the lower surface of the liquid-impermeable bottom layer and the inner surface of the outer casing, wherein a strip opening is arranged at the top of the outer casing, wherein a sealing strip is arranged at the top of the strip opening, wherein the width of the sealing strip is greater than the width of the strip opening, wherein the sealing strip extends from one end of the strip opening to the other end of the strip opening and is bonded to the top of the outer casing by a biodegradable adhesive, wherein a wet-indicating strip is arranged at the bottom of the sealing strip.

[0017] 1. The absorbent body of the utility model includes an outer body and an absorbent sheet. An oxidative decomposition agent is attached to the inner surface of the outer body. After the outer body is opened for use, the oxidative decomposition agent arranged on the outer body comes into contact with moisture in the air or soil, and then decomposes the outer body. Similarly, the oxidative decomposition agent arranged on the lower surface of the liquid-impermeable bottom layer can decompose the liquid-impermeable bottom layer that is difficult to degrade after the user uses and discards it.

[0018] 2. The utility model ensures the sealing of the outer package by setting the strip opening and the sealing strip, so as to prevent the oxidizing decomposition agent contained inside from contacting the moisture in the air and stimulating the decomposition function of the oxidizing decomposition agent. The setting of the moisture-indicating strip can more intuitively judge whether water has entered the outer package. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] 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.

[0028] Example

[0029] like Figures 1 to 3 As shown, a degradable diaper comprises an absorbent body 1, wherein the absorbent body 1 comprises an outer body 2 and an absorbent sheet 3, wherein the absorbent sheet 3 is arranged in the outer body 2, wherein the absorbent sheet 3 comprises a liquid-permeable surface layer 31, a liquid-impermeable bottom layer 32 and an absorbent core 33 between the liquid-permeable surface layer 31 and the liquid-impermeable bottom layer 32, wherein an oxidizing decomposition agent 4 is attached to the lower surface of the liquid-impermeable bottom layer 32 and the inner surface of the outer body 2, wherein a strip opening 21 is arranged at the top of the outer body 2 in a U-shape along the length direction of the absorbent body 1, wherein a sealing strip 22 is arranged at the top of the strip opening 21, wherein the width of the sealing strip 22 is greater than the width of the strip opening 21, wherein the sealing strip 22 extends from one end of the strip opening 21 to the other end of the strip opening 21, and is bonded to the top of the outer body 2 by a biodegradable adhesive, wherein a wet-indicating strip 23 is arranged at the bottom of the sealing strip 22;

[0030] The biodegradable adhesive is an existing material and will not be described in detail here;

[0031] The oxidizing decomposition agent 4 attached to the inner surface of the outer package 2 is attached to the inner surface through a water-sensitive film (not shown in the figure) and the outer package 2 by heat pressing. The water-sensitive film is made of PC material. The lower surface of the liquid-impermeable bottom layer 32 is provided with a non-woven fabric covering layer 34. The oxidizing decomposition agent 4 set on the lower surface of the liquid-impermeable bottom layer 32 is attached to the lower surface of the liquid-impermeable bottom layer 32 by heat pressing the liquid-impermeable bottom layer 32 and the non-woven fabric covering layer 34.

[0032] The top of the absorbent sheet 3 is provided with a guide groove 35, the guide groove 35 is arranged along the length direction of the absorbent sheet 3, and is arranged on both sides of the absorbent sheet 3. The oxidative decomposition agent 4 is a mixture of carboxylate and soluble rare earth salt. The material of the outer package 2 and the sealing strip is polylactic acid. The liquid permeable surface layer 31 is made of antibacterial pure cotton non-woven fabric. The absorbent core 33 is made of dust-free paper 36 covered with polymer composite absorbent paper 37;

[0033] By attaching the oxidizing decomposition agent 4 to the inner surface of the outer package 2, after the outer package 2 is opened for use, the oxidizing decomposition agent 4 disposed on the outer package 2 comes into contact with moisture in the air or soil, thereby decomposing the outer package 2. Similarly, the oxidizing decomposition agent 4 disposed on the lower surface of the liquid-impermeable bottom layer 32 can decompose the liquid-impermeable bottom layer 32 which is difficult to degrade after the user discards it. The sealing of the outer package 2 is ensured by the arrangement of the strip-shaped opening 21 and the sealing strip 22, so as to prevent the oxidizing decomposition agent contained inside from contacting moisture in the air and stimulating the decomposition function of the oxidizing decomposition agent 4. The arrangement of the moisture-indicating strip 23 can more intuitively determine whether water has entered the outer package 2.

[0034] The wet strip 23 uses the principle that cobalt chloride changes color after absorbing water, which is a conventional technical means and will not be described in detail here;

[0035] The absorbent core 33 is provided with a plurality of water-sensitive capsules 38, each of which is provided with the oxidizing decomposing agent 4; the total mass of the oxidizing decomposing agent 4 in each of the water-sensitive capsules 38 does not exceed 10% of the total mass of the oxidizing decomposing agent 4 attached to the lower surface of the liquid-impermeable bottom layer 32. The dust-free paper 36 and the polymer composite absorbent paper 37 included in the absorbent core 33 are highly degradable, so there is no need for too much oxidizing decomposing agent 4;

[0036] The water-sensitive capsule is made of PC material;

[0037] In this embodiment, there are two water-sensitive capsules 38, which are spaced apart along the length direction of the absorbent core 33. The water-sensitive capsules 38 are disposed below the polymer composite absorbent paper 37 to avoid premature destruction of the water-sensitive capsules 38 during use.

[0038] 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.
