[0031] like Figure 1-4 , the utility model provides a leakage-proof sanitary product on one hand, comprising a surface layer 11, an absorption layer 12 and a liquid barrier layer 13 arranged in sequence from top to bottom;
[0032] A leak-proof structure is provided at the rear end of the surface layer 11, and the leak-proof structure includes at least one pleat 111 arranged along the width direction; each pleat is provided with at least one fixing portion 111b, and the fixing portion 111b is used to fix the pleat 111 and divide the pleat 111 into a plurality of discontinuous small pleats 111a.
[0033] The utility model has pleats at the rear end of the surface layer as a leak-proof structure, which can increase the resistance of excrement flow, effectively prevent human excrement from flowing backward, and play a role in preventing back leakage; at the same time, a discontinuous fixing part is arranged on each pleat, which can not only play a role in fixing the pleats, but also divide each pleat into a plurality of discontinuous small pleats, so that human excrement can be prevented from flowing along the pleats to both sides in the width direction, effectively preventing side leakage. The sanitary product provided by the utility model can effectively prevent side leakage and back leakage by arranging a pleat leak-proof structure on the surface layer.
[0034] It should be noted that the above-mentioned “rear end” refers to the side close to the back of the human body during use.
[0035] In some preferred embodiments of the present invention, the wrinkles 111 are formed at the rear end of the surface layer by using a surface wrinkling technology, so as to prevent the liquid from flowing backward and leaking backward.
[0036] In some preferred embodiments of the present invention, the pleats 111 are formed by overlapping the rear ends of the surface layers, and the pleats 111 are adhered to the surface layer 11 of the sanitary product toward the front end of the surface layer 11, and the two ends of the pleats 111 are sealed and pressed together with the surface layer 11, and the middle part of the pleats 111 naturally adheres to the surface of the sanitary product.
[0037] In some preferred embodiments of the utility model, the pleats 111 are fixed by heat pressing or gluing to form a fixing portion 111b on the pleats 111. The fixing portion 111b divides the pleats 111 into a plurality of small pleats 111a, thereby preventing liquid from flowing out to both sides along the pleats 111 and preventing side leakage.
[0038] In some preferred embodiments of the present invention, the surface layer 11 is a single-layer or multi-layer structure; wherein the single-layer material is a non-woven fabric, preferably one or more of spunbond non-woven fabric, hot air non-woven fabric, and spunlace non-woven fabric.
[0039] In some preferred embodiments of the present invention, the weight of the single layer material in the surface layer 11 is 10 to 60 g / m 2 (For example, it can be 10g / m 2 , 15g / m 2 , 20g / m 2 , 25g / m 2 , 30g / m 2 , 35g / m 2 , 40g / m 2 , 45g / m 2 , 50g / m 2 , 55g / m 2 or 60g / m 2 ).
[0040] In some preferred embodiments of the present invention, the interval between two adjacent folds 111 along the length direction is 5 to 10 mm (for example, it may be 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm or 10 mm).
[0041] In some preferred embodiments of the present invention, the number of the pleats 111 is 1 to 20 (for example, it can be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 or 20).
[0042] In some preferred embodiments of the present invention, the height of the folds 111 is 2 to 15 mm (for example, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm or 15 mm). It should be noted that the height of the folds is the vertical distance between the top of the folds and the surface of the sanitary product.
[0043] In some preferred embodiments of the present invention, the number of the fixing portions 111b on each of the folds 111 is 1 to 11 (for example, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or 11).
[0044] In some preferred embodiments of the present invention, the width of the fixing portion 111b is 0.5-5 mm (for example, 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm or 5 mm).
[0045] In some preferred embodiments of the present invention, the distance between adjacent fixing portions 111b in each of the folds 111 is 10 to 50 mm (for example, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm or 50 mm).
[0046] In some preferred embodiments of the present invention, the fixing portions 111b in two adjacent folds 111 are staggered. The staggered arrangement of the fixing portions in two adjacent folds means that the fixing portions in the two adjacent folds are not in correspondence with each other and are staggered (e.g. Figure 2 As shown), this can achieve layer-by-layer barrier for liquids and effectively improve the anti-leakage effect.
[0047] In some preferred embodiments of the present invention, a flow blocking component is provided at the rear end of the absorbent layer 12. By providing the flow blocking component at the rear end of the absorbent layer, it can prevent the liquid from flowing backward and absorb the liquid, and cooperate with the anti-leakage structure of the surface layer to further improve the anti-rear leakage effect.
[0048] In some preferred embodiments of the present invention, the absorbent layer 12 is composed of one or more layers of absorbent paper, and the weight of the absorbent paper is preferably 60 to 250 g / m 2 (For example, it can be 60g / m 2 , 80g / m 2 , 100g / m 2 , 120g / m 2 , 150g / m 2 , 180g / m 2 , 200g / m2 , 220g / m 2 or 250g / m 2 ).
[0049] In some preferred embodiments of the present invention, the flow blocking component includes at least one flow blocking strip 121 distributed along the width direction. The flow blocking component includes multiple flow blocking strips distributed along the width direction, which can play the role of layer-by-layer flow blocking and absorbing liquid, and has an excellent anti-rear leakage effect.
[0050] In some preferred embodiments of the present invention, the flow-blocking strip 121 is a strip-shaped fluff pulp structure. The fluff pulp structure with excellent absorption performance is used as the flow-blocking strip, which can absorb liquid while preventing the liquid from flowing backward.
[0051] In some preferred embodiments of the present invention, the flow blocking component includes 1 to 10 flow blocking strips 121 .
[0052] In some preferred embodiments of the present invention, the distance between adjacent blocking strips 121 is 5 to 20 mm (for example, 5 mm, 6 mm, 8 mm, 10 mm, 12 mm, 14 mm, 16 mm, 18 mm or 20 mm).
[0053] In some preferred embodiments of the present invention, the width of the baffle strip 121 is 1 to 10 mm (for example, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm).
[0054] In some preferred embodiments of the present invention, the height of the baffle strip 121 is 1 to 3 mm (for example, 1 mm, 1.5 mm, 2 mm, 2.5 mm or 3 mm).
[0055] In some preferred embodiments of the present invention, the liquid barrier layer 13 is a single-layer or multi-layer structure; the single-layer material of the liquid barrier layer 13 is a PE film or a water-repellent non-woven fabric; preferably, the gram weight of the PE film is 20 to 60 g / m 2 (For example, it can be 20g / m 2 , 25g / m 2 , 30g / m 2 , 35g / m 2 , 40g / m 2 , 45g / m 2 , 50g / m 2 , 55g / m 2 or 60g / m 2 ), the weight of water-repellent nonwoven fabric is 15~90g / m 2 (For example, it can be 15g / m 2, 20g / m 2 , 25g / m 2 , 30g / m 2 , 35g / m 2 , 40g / m 2 , 45g / m 2 , 50g / m 2 , 55g / m 2 , 60g / m 2 , 65g / m 2 , 70g / m 2 , 75g / m 2 , 80g / m 2 , 85g / m 2 or 90g / m 2 ).
