Description

Technical Field

[0001] This utility model relates to the field of absorbents, specifically to a leak-proof absorbent. Background Technology

[0002] Disposable diapers are widely used due to their convenience, hygiene, comfort, and ease of use. However, leakage can easily occur in the back of the diaper for infants and young children due to the following reasons: 1. Material issues: Problems with the diaper material, such as poor absorbency and water retention, can lead to leakage. 2. Incorrect fitting: For example, an improperly adjusted waistband that is too loose increases the probability of leakage. 3. Leak-proof side panels not properly secured: If the leak-proof side panels of the diaper are not properly secured, it can also cause leakage at the waist. 4. Active infants: Movement by the infant can cause the diaper to shift, or actions such as rolling over or lifting legs after urinating can also cause back leakage. Back leakage of diapers, especially in winter, can cause considerable cleaning trouble due to urine or feces staining clothes and bedding.

[0003] Although improving diaper materials and choosing the right size and wearing them correctly can effectively improve back leakage, back leakage is still prone to occur due to the structural limitations of diapers.

[0004] Moreover, in addition to baby diapers, the absorbent cores of women's menstrual pants and adult diapers are also prone to leakage problems, which are far from meeting industry requirements. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a leak-proof absorbent that can reduce back leakage.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A leak-proof absorbent includes an absorbent functional layer, a surface layer, a side leakage protection barrier, and a rear leakage prevention elastic expansion member; the side leakage protection barriers are provided on both sides of the absorbent functional layer; the surface layer is disposed on the absorbent functional layer; the rear leakage prevention elastic expansion member is connected to the rear end of the surface layer, and the two sides of the rear leakage prevention elastic expansion member are respectively arranged to intersect with the side leakage protection barriers on both sides of the absorbent functional layer; each side of the rear leakage prevention elastic expansion member is disposed between the surface layer and the corresponding side leakage protection barrier.

[0008] The anti-leakage elastic expansion component includes an elastic element layer, a first cover layer, and a second cover layer; the elastic element layer is disposed between the first cover layer and the second cover layer.

[0009] The elastic element layer comprises multiple rubber bands arranged in sequence.

[0010] The spacing between two adjacent elastic bands is 1.5-3.5mm, and the elongation ratio of the elastic band is 1.8-2.8 times.

[0011] The first covering layer is a water-repellent hot air nonwoven fabric layer.

[0012] The second covering layer is a water-repellent spunbond nonwoven fabric layer or a water-repellent hot air nonwoven fabric layer.

[0013] Each side of the anti-leakage elastic telescopic component is bonded between the bottom of the corresponding anti-leakage guard and the top of the surface layer.

[0014] The rear end of the anti-leakage elastic expansion component is connected to the surface layer, and the anti-leakage elastic expansion component, the anti-side leakage guard and the surface layer form a composite cavity.

[0015] The surface layer is at least partially located between the side leakage protection barriers on both sides of the absorbent functional layer.

[0016] The length of the anti-leakage elastic telescopic component is 35mm-60mm or 35mm-80mm.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model provides a leak-proof absorbent body that combines an absorbent functional layer, a surface layer, a side leakage-proof guard, and a back leakage-proof elastic telescopic component. When infants use the product, the back leakage-proof elastic telescopic component effectively prevents loose stools from extending to the lower back and also blocks some flowing urine, extending the absorption time of the absorbent functional layer for absorbing urine and loose stools, thus reducing back leakage. Furthermore, by forming a composite cavity with the back leakage-proof elastic telescopic component, the side leakage-proof guard, and the surface layer, it can hold excrement in place if it is not absorbed in time, preventing it from flowing backward and overflowing from the lower back, thus preventing back leakage. In addition, it can also prevent urine from flowing outside the side leakage-proof guards on both sides, improving the side leakage-proof performance. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example 1

[0026] like Figure 1-3 As shown, a leak-proof absorbent includes an absorbent functional layer 10, a surface layer 20, a side leakage protection barrier 30, and a rear leakage prevention elastic expansion member 40. The side leakage protection barriers 30 are provided on both sides of the absorbent functional layer 10. The surface layer 20 is disposed on the absorbent functional layer 10. The rear leakage prevention elastic expansion member 40 is connected to the rear end of the surface layer 20, and both sides of the rear leakage prevention elastic expansion member 40 are respectively arranged intersecting with the side leakage protection barriers 30 on both sides of the absorbent functional layer 10. Each side of the rear leakage prevention elastic expansion member 40 is disposed between the surface layer 20 and the corresponding side leakage protection barrier 30.

[0027] This utility model provides a leak-proof absorbent body, which combines an absorbent functional layer 10, a surface layer 20, a side leakage protection barrier 30, and a back leakage prevention elastic telescopic component 40. When infants and young children use the product, the back leakage prevention elastic telescopic component 40 can effectively prevent the infant's loose stool from extending to the lower back and can also block some of the flowing urine. This extends the absorption time of the absorbent functional layer 10, which absorbs urine and loose stool, reducing back leakage and making the side leakage prevention function stronger and less prone to side leakage.

[0028] The absorbent layer 10 can be any existing absorbent layer 10. In this embodiment, the absorbent layer 10 uses an absorbent layer with a built-in elastic waistband to enhance the back leakage prevention function. The absorbent layer 10 has ear patches 50 on both sides.

[0029] Preferably, the anti-leakage elastic telescopic component 40 includes an elastic element layer 41, a first cover layer 42, and a second cover layer 43; the elastic element layer 41 is disposed between the first cover layer 42 and the second cover layer 43, thereby facilitating the fabrication and formation of the anti-leakage elastic telescopic component 40.

[0030] Specifically, the elastic element layer 41 is bonded and fixed between the first cover layer 42 and the second cover layer 43 by hot melt adhesive to facilitate fixation.

[0031] The elastic element layer 41 comprises multiple elastic bands arranged sequentially. Specifically, the elastic bands have a diameter of 70-280D. The spacing between two adjacent elastic bands is 1.5-3.5mm, and the elongation ratio of the elastic bands is 1.8-2.8 times.

[0032] The spacing between two adjacent elastic bands and the stretch ratio of the elastic bands can be selected according to actual needs. However, setting the spacing between two adjacent elastic bands to 1.5-3.5mm and the stretch ratio of the elastic bands to 1.8-2.8 times is the most preferred embodiment of this utility model, which can improve the elastic performance.

[0033] Preferably, the first covering layer 42 is a water-repellent hot-air nonwoven fabric layer. Preferably, the second covering layer 43 can be a water-repellent spunbond nonwoven fabric layer, which can ensure performance and reduce costs. The water-repellent hot-air nonwoven fabric layer weighs 15-20g, and the water-repellent spunbond nonwoven fabric layer weighs 8-15g.

[0034] Of course, in addition to this, the first covering layer 42 and the second covering layer 43 can also be made of water-repellent hot air nonwoven fabric, which can also ensure performance and reduce costs. Specifically, the water-repellent hot air nonwoven fabric layer weighs 15-20g. In the manufacturing process, the fine denier elastic of the elastic element layer 41 can be glued and bonded to the water-repellent hot air nonwoven fabric first, and then the water-repellent hot air nonwoven fabric is folded in half to form a leak-proof elastic stretching component 40. The water-repellent hot air nonwoven fabric portions on both sides of the elastic element layer 41 are respectively formed as the first covering layer 42 and the second covering layer 43.

[0035] The elastic element layer 41 is bonded and fixed between the first cover layer 42 and the second cover layer 43 by hot melt adhesive. Specifically, each side of the anti-leakage elastic telescopic component 40 is bonded between the bottom of the corresponding anti-leakage guard 30 and the top of the surface layer 20.

[0036] The rear end of the anti-leakage elastic stretch member 40 is connected to the surface layer 20, and the anti-leakage elastic stretch member 40, the anti-side leakage guard 30, and the surface layer 20 form a composite cavity. The edge of the anti-leakage elastic stretch member 40 facing the front end of the surface layer 20 is a movable edge, making the position of the composite cavity facing the front end of the surface layer 20 an opening. The edge of the anti-leakage elastic stretch member 40 facing the rear end of the surface layer 20 is fixedly connected to the surface layer 20, and the edges of the two sides of the anti-leakage elastic stretch member 40 are fixedly connected to the anti-side leakage guard 30 and the surface layer 20, so that the edge of the composite cavity facing the rear end of the surface layer 20 and the edges of the two sides of the absorbent layer 10 are in a closed state. Human excrement can enter the composite cavity through the opening, and is thus confined inside the diaper by the closed edges of the composite cavity, thereby preventing leakage.

[0037] In use, the rear end of the absorbent body fits snugly against the skin of the lower back. The anti-leakage elastic stretching component 40 also fits snugly against the skin. The anti-leakage elastic stretching component 40, the anti-side leakage guard 30, and the surface layer 20 form a composite cavity. When excrement is not absorbed in time, the composite cavity contains the excrement, preventing it from flowing backward and overflowing from the lower back, thus avoiding staining clothes and bedding and preventing back leakage. The rear end of the anti-leakage elastic stretching component 40 (e.g., the edge of the anti-leakage elastic stretching component 40 facing the rear end of the surface layer 20) is bonded to the surface layer 20 with a hot melt adhesive layer (bonding area) with a width of 8-20mm.

[0038] The surface layer 20 is at least partially located between the side leakage protection barriers 30 on both sides of the absorbent functional layer 10.

[0039] Preferably, the length of the anti-leakage elastic telescopic component 40 is 35mm-60mm. The width of the anti-leakage elastic telescopic component 40 is equidistant from the width of the surface layer 20.

[0047] The spacing between two adjacent elastic bands and the stretch ratio of the elastic bands can be selected according to actual needs. However, setting the spacing between two adjacent elastic bands to 1.5-3.5mm and the stretch ratio of the elastic bands to 1.8-2.8 times is the most preferred embodiment of this utility model, which can improve the elastic performance.

[0049] Of course, in addition to this, the first covering layer 42 and the second covering layer 43 can also be made of water-repellent hot air nonwoven fabric, which can also ensure performance and reduce costs. Specifically, the water-repellent hot air nonwoven fabric layer weighs 15-20g.

The water-repellent hot air nonwoven fabric portions on both sides of the elastic element layer 41 are respectively formed as the first covering layer 42 and the second covering layer 43.

[0050] The elastic element layer 41 is bonded and fixed between the first cover layer 42 and the second cover layer 43 by hot melt adhesive. Specifically, each side of the anti-leakage elastic telescopic component 40 is bonded between the bottom of the corresponding anti-leakage guard 30 and the top of the surface layer 20.
