Detailed implementation manners

[0024] The present utility model will be further described below in conjunction with the accompanying drawings and specific implementation manners.

[0025] Refer to Figures 1 to 5 , this embodiment provides a leak-proof waist diaper, which sequentially includes a base layer 1, a liquid-impermeable bottom layer 2, an absorption layer 3, a hydrophobic layer 4, a waist absorption layer 5, and elastic gaskets 6 located on both sides of the hydrophobic layer 4 from bottom to top;

[0026] The upper and lower sides of the base layer 1 have a front waist area 1a and a rear waist area 1b, the middle of the base layer 1 has an absorption area 1c, and multiple elastic components 7 are provided on the base layer 1 in the front waist area 1a and the rear waist area 1b;

[0027] The two sides of the front waist area 1a and the rear waist area 1b of the base layer 1 are welded to form a welding part 8, the waist absorption layer 5 is located in the front waist area 1a and / or the rear waist area 1b of the base layer 1, the absorption layer 3 is located in the absorption area 1c in the middle of the base layer 1, the liquid-impermeable bottom layer 2 covers the front waist area 1a, the rear waist area 1b and the absorption area 1c of the base layer 1, the waist absorption layer 5 includes fluff pulp, a superabsorbent polymer, and a hydrophilic non-woven fabric for coating the fluff pulp and the superabsorbent polymer. The ratio and manufacturing process of the fluff pulp and the superabsorbent polymer are both conventional existing technologies and will not be elaborated here. The liquid-impermeable bottom layer is a breathable bottom film, which can repel water from the absorption layer and the waist absorption layer, prevent liquid from leaking from the base layer, and cooperate with the waist absorption layer to achieve a good absorption effect.

[0028] The waist absorption layer 5 further includes fluff pulp, a superabsorbent polymer, and carbon particles mixed with the fluff pulp and the superabsorbent polymer. The waist absorber can also be a composite core, which is an existing technology and will not be elaborated here. The ratio of the carbon particles to the water-absorbing resin is 0.02 to 0.1:1, and the carbon particles can remove strange smells and odors from the waist absorption layer and reduce the odor during use.

[0029] Especially when used by men, the waist absorbent layer 5 is located in the front waist area 1a and the back waist area 1b of the base layer 1. When urine does not reach the middle absorption area, the waist absorbent layers in the front waist area and the back waist area will absorb it to prevent urine from leaking from the waist area. The unfixed urination direction specifically refers to that when the human body lies flat or sideways, the direction of male genital urine is unfixed, and it is easy to urinate in the waist area other than the middle absorption core, while the existing absorbent pants do not specifically absorb the waist area. The diaper has a good effect on male users. The waist absorbent layer can solve the problem that the existing human body lies down and uses diapers, and the urine is easy to leak from the waist of the diaper due to the unfixed urination direction. The waist absorbent layer 5 can also be located only in the back waist area 1b or in the front waist area 1a and the back waist area 1b, which can also prevent female urine leakage, not only male urine leakage, and can be used by both men and women.

[0030] The distance between the waist absorbent layer 5 and the welding part 8 is 1mm-50mm. Since the base layer 1 needs to be folded in half and welded from both sides, the waist absorbent layer is spaced apart from the two sides to facilitate welding on both sides of the base layer without interfering.

[0031] The elastic component 7 includes a top elastic rubber band 7a and a middle elastic rubber band 7b. The elastic force of the top elastic rubber band 7a is greater than that of the middle elastic rubber band 7b. The distance between the top elastic rubber band 7a and the waist absorbent layer 5 is 2mm to 10mm. The spacing between the top elastic rubber bands 7a is 1mm to 5mm, and the spacing between the middle elastic rubber bands 7b is 4mm to 14mm.

[0032] Since the waist absorbent layer has a certain thickness and is affected by the contraction of the middle elastic rubber band, there is a certain gap in the waist absorbent layer after it is gathered, which poses a risk of leakage. When the elastic force of the top elastic rubber band 7a is greater than that of the middle elastic rubber band 7b, the interval between the top elastic rubber band and the middle elastic rubber band is 4mm to 14mm, and the interval area of ​​the base layer is affected by the top elastic rubber band, the waist absorbent layer is tightly attached to the human waist to prevent liquid from leaking from the gap in the waist absorbent layer and the base layer, while avoiding the problem that the waist absorbent layer has a certain weight after absorption and the diaper is easy to fall. The elastic force of the middle elastic rubber band is weaker than that of the top elastic rubber band, which can avoid the defect of the waist absorbent layer being tightly bound, and because of the loose elastic force, the waist absorbent layer will not feel wet when it contacts the skin after absorption.

[0033] The base layer 1 is provided with a first U-shaped elastic band 9 extending downward by 5 to 12 cm at the rear waistline. There are more than two first U-shaped elastic bands 9, and at least one of the first U-shaped elastic bands 9 has a first cut portion 10 in the middle.

[0034] The downward extension distance of the first U-shaped elastic band 9 is denoted by the reference numeral a. The first U-shaped elastic band can make the diaper fit the human buttocks better, improving the absorption effect in the human buttocks area. The setting of the first cutting portion can reduce the elasticity of the first U-shaped elastic band and avoid a tight feeling caused by the first U-shaped elastic band.

[0035] The base layer 1 is provided with a second U-shaped elastic band 11 at the front waist circumference. The middle of the base layer 1 has a folding line 13. The second U-shaped elastic band 11 extends to the folding line 13. There are more than two second U-shaped elastic bands 11, and at least one of the second U-shaped elastic bands 11 has a second cutting portion 12 in the middle.

[0036] The second U-shaped elastic band 11 extends downward by 10 to 15 cm. The downward extension is denoted by the reference numeral b. The second U-shaped elastic band can improve the lifting effect of the absorbent layer of the diaper after absorbing liquid. The second cutting portion can reduce the elasticity of the second U-shaped elastic band and reduce wrinkles caused by excessive elasticity of the absorbent layer during use.

[0037] Elastic wires 5a are provided on the side of the waist absorbent layer 5 along the length direction. The elastic wires 5a can make the waist absorbent layer 5 stand up, further improving the leakage prevention effect.
