Description

TECHNICAL FIELD

[0001] The utility model relates to absorbent article technical field, specifically disclose an absorbent article with front and back leakproof structure. BACKGROUND

[0002] In the traditional design of absorbent articles such as paper diapers, the leakproof function is mainly realized by the side leakage prevention three-dimensional containment on both sides in the transverse direction, and the side leakage prevention three-dimensional containment is usually composed of elastic materials, which is used to block the lateral leakage of excreta by fitting the leg contour of the user, however, the existing technology generally lacks longitudinal (i.e. the front and back direction of the product) leakproof structure, especially the front and back ends of the absorbent article lack effective sealing barriers, when the user is in a lying, side-lying or strenuous exercise state, the high fluidity of the feces or urine is easy to move along the longitudinal direction due to the action of gravity or dynamic extrusion, and thus seeps from the front and back edges of the product, thereby reducing the use effect and user comfort of the absorbent article.

[0003] To solve the problem of insufficient longitudinal leakproofness of the traditional absorbent article, the existing technology proposes an absorbent article with front and back leakproofness (such as patent CN208641042U), which sets an absorbent core layer between the hydrophilic surface layer and the waterproof bottom layer, and configures a side leakage prevention three-dimensional containment on both sides in the transverse direction, and additionally provides an elastic waist structure at both ends in the longitudinal direction, specifically, the elastic waist is fixed at the longitudinal end of the hydrophilic surface layer, the transverse sides thereof are adhered to the longitudinal ends of the three-dimensional containment, and the connection is closed by sealing glue, through the contraction characteristics of the elastic waist, the design intends to form a continuous closed leakproof barrier at both ends of the absorbent article in the longitudinal direction, so as to limit the diffusion of excreta along the longitudinal leakage path, thereby improving the leakproof performance.

[0004] Although the above-mentioned technology realizes the preliminary construction of the longitudinal leakproof structure through the cooperation of the elastic waist and the sealing glue, the actual leakproof effect still has significant deficiencies, because the fixing mode of the elastic waist is a full-closed connection by the sealing glue, and the fit degree of the elastic waist to the waist and abdomen of the user is limited by the material elasticity and the adaptability of human dynamic deformation, when the user performs actions such as lying, rolling, etc., the contact pressure distribution between the waist and abdomen and the absorbent article changes, the elastic waist is difficult to fit the skin folds or body curves in real time, and thus the excreta is easy to seep from the gap between the waist and the skin.

DETAILED DESCRIPTION

[0026] The embodiments of the present application are described below in conjunction with the accompanying drawings and related embodiments, and the embodiments of the present application are not limited to the following examples, and the present application relates to the necessary components in the related technical field, which should be regarded as the known technology in the technical field, and can be known and mastered by the skilled in the art.

[0027] In combination with Figures 1 to 5 As shown in the drawings, an absorbent article with front and rear leakage prevention structure includes an absorbent body 1 and a waist circumference part 2 arranged at both ends of the absorbent body 1, the outer side of the absorbent body 1 is sequentially provided with an inner layer waist circumference non-woven fabric 4 and an outer layer waist circumference non-woven fabric 3, the inner layer waist circumference non-woven fabric 4 and the outer layer waist circumference non-woven fabric 3 extend to the upper end of the absorbent body 1 and are symmetrically folded inward on the inner side of the absorbent body 1 to form the waist circumference part 2, the waist circumference part 2 is provided with a waist circumference upper part 22 and a waist circumference lower part 23, both ends of the outer layer waist circumference non-woven fabric 3 are symmetrically folded inward on the inner side of the absorbent body 1 at the waist circumference upper part 22 and are arranged at the middle position of the waist circumference part 2, both ends of the inner layer waist circumference non-woven fabric 4 are sequentially symmetrically folded inward on the inner side of the absorbent body 1 at the waist circumference upper part 22, symmetrically folded at the waist circumference lower part 23 and form a leakage prevention pocket at the waist circumference lower part 23.

[0028] The leakage prevention pocket of the present application is formed by symmetrically folding the inner layer waist circumference non-woven fabric 4 at the waist circumference lower part 23 outward or inward on the inner side of the absorbent body 1, so that the leakage prevention pocket becomes a leakage prevention barrier, which can effectively catch and block the excrement that may overflow from the front and rear of the absorbent body 1, the elastic spandex filament arranged in the leakage prevention pocket has good elastic and stretching properties, so that the leakage prevention pocket is more three-dimensional, and ensures that the leakage prevention pocket can closely fit the waist and abdomen of the user during wearing, the multi-layer structure of the absorbent body 1 including the surface layer 11, the flow guide layer 12, the absorbent core 13 and the leakage prevention and air permeable PE film layer 14 cooperates with the leakage prevention pocket, which together improves the leakage prevention performance of the absorbent article, even if part of the excrement is not completely absorbed after being absorbed by the absorbent body 1, it will also be caught by the leakage prevention pocket, thereby preventing leakage.

[0029] In the prior art, the outermost liquid-impermeable layer of the absorbent article is usually directly folded inward symmetrically to form the front and rear leakage-proof structures. Although this method is simple, it may not be ideal for the fit of the leakage-proof structure to the waist and abdomen of the user due to the single material and symmetric folding method. In contrast, in the scheme of the present application, the inner layer waist circumference non-woven fabric 4 is symmetrically folded inward at the lower waist circumference 23 to form a leakage-proof pocket on the inner side or outer side of the absorbent main body 1. The inner layer waist circumference non-woven fabric 4 at the leakage-proof pocket area forms a multi-layer structure due to the folding, and the elastic spandex filaments are arranged in the multi-layer structure of the inner layer waist circumference non-woven fabric 4. The elastic stretchability of the elastic spandex filaments makes the leakage-proof pocket more three-dimensional and ensures that it is always closely fitted to the waist and abdomen of the user during wearing, thereby increasing the front and rear leakage-proof effect of the leakage-proof pocket.

[0030] As shown in Figures 1 to 5 , as a further improvement of the above scheme, a plurality of first elastic spandex filaments 5 are arranged equidistantly along the height direction of the waist circumference 2 between the inner layer waist circumference non-woven fabric 4 and the outer layer waist circumference non-woven fabric 3 on the outer side of the waist circumference 2.

[0031] The first elastic spandex filaments 5 are arranged equidistantly between the inner layer waist circumference non-woven fabric 4 and the outer layer waist circumference non-woven fabric 3 on the outer side of the waist circumference 2, so that the waist circumference 2 has good elasticity and can adapt to the waist circumference sizes of different users, ensuring that the absorbent article can be closely fitted to the waist and abdomen of the user during wearing. The stretchability of the elastic spandex filaments makes the waist circumference 2 more flexible in adapting to the body curves of the user, providing a comfortable wearing experience and reducing the risk of leakage due to size mismatch.

[0032] As shown in Figure 1 , as one of the preferred embodiments of the present application, the inner layer waist circumference non-woven fabric 4 is symmetrically folded outward at both ends at the lower waist circumference 23 to form a first leakage-proof pocket 21 on the outer side of the absorbent main body 1.

[0033] The inner waistband nonwoven fabric 4 has two ends folded at the lower part 23 of the waistband to form a first leak-proof pocket 21. The first leak-proof pocket 21 enhances the front and rear leak-proof effect of the absorbent product. The formation process of the waistband 2 is as follows: the inner waistband nonwoven fabric 4 and the outer waistband nonwoven fabric 3 are sequentially placed on the outside of the absorbent body 1. The two ends of these two nonwoven fabrics extend towards the upper part 22 of the waistband, and when they reach the upper part 22 of the waistband, they are symmetrically folded towards the inside of the absorbent body 1 for the first time. At this time, the two ends of the outer waistband nonwoven fabric 3 are placed in the middle after being symmetrically folded. At the middle position of the waist section 2, the inner waist non-woven fabric 4 continues to extend towards the lower waist section 23. When it reaches the lower waist section 23, the inner waist non-woven fabric 4 is folded symmetrically towards the outside of the absorbent body 1 for the second time. After this symmetrical fold, the first leak-proof pocket 21 is formed at the lower waist section 23. At the same time, after the two ends of the inner waist non-woven fabric 4 are symmetrically folded towards the outside of the absorbent body 1 at the lower waist section 23, they are placed in the middle position inside the waist section 2, cooperating with the outer waist non-woven fabric 3 to jointly form the first folding structure of the waist section 2.

[0034] like Figure 1 As shown, as a further improvement of the above embodiment, a plurality of second elastic spandex filaments 6 are arranged equidistantly along the height direction of the first leak-proof pocket 21 between the two inner layers of waistband nonwoven fabric 4 at the position of the first leak-proof pocket 21 of the lower waistband 23.

[0035] The main function of the first leak-proof pocket 21 is to prevent excrement from leaking from the front and back of the absorbent. The addition of the second elastic spandex 6 makes the first leak-proof pocket 21 more secure and tight, effectively blocking the overflow of excrement. At the same time, the elasticity of the second elastic spandex 6 also helps to maintain the shape and position of the first leak-proof pocket 21 during wear, ensuring that it always plays a good leak-proof role.

[0036] The second elastic spandex yarn 6 is arranged at equal intervals along the height direction of the first leak-proof pocket 21. Its inherent elasticity allows the first leak-proof pocket 21 to maintain a certain three-dimensional shape during wear, which helps the first leak-proof pocket 21 to better fit the user's waist and abdomen, forming an effective leak-proof barrier. At the same time, the elasticity and stretchability of the second elastic spandex yarn 6 allows the first leak-proof pocket 21 to adapt to the waist and abdomen size and shape of different users, ensuring that it always fits closely to the user's body during wear. This fit not only improves the leak-proof effect, but also enhances the user's comfort.

[0037] like Figure 2 As shown, as a further improvement to the above embodiment, a soft and fluffy layer 9 is provided between the second elastic spandex filament 6 and the inner waistband nonwoven fabric 4 on the outside of the first leak-proof pocket 21.

[0038] The main function of the soft and fluffy layer 9 is to improve the wearing comfort of the absorbent article, which can reduce the direct contact pressure of the waist portion 2 on the user's waist skin, making the wearing more soft and comfortable. The presence of the soft and fluffy layer 9 helps the first leakage prevention pocket 21 to better fit the user's waist and abdomen, which can adapt to the user's body curve to some extent, so that the first leakage prevention pocket 21 can be more closely attached to the skin during wearing, thereby improving the leakage prevention effect. The soft and fluffy layer 9 can be made of soft materials such as fluffy cloth, sponge and pure cotton cloth, thereby improving the wearing experience of the user.

[0039] As shown in Figure 3 As one of the preferred embodiments of the present application, the inner layer waist circumference non-woven fabric 4 is folded twice at the lower part 23 of the waist circumference to the inner side of the absorption main body 1, and forms the second leakage prevention pocket 24 and the extension layer 241 located on the side of the second leakage prevention pocket 24 away from the absorption main body 1.

[0040] In another structure of the waist portion 2 of the absorbent article of the present application, the second leakage prevention pocket 24 and the extension layer 241 are formed by folding the inner layer waist circumference non-woven fabric 4 twice at the lower part 23 of the waist circumference, and the specific process is as follows:

[0041] The inner layer waist circumference non-woven fabric 4 and the outer layer waist circumference non-woven fabric 3 are sequentially arranged on the outer side of the absorption main body 1, and the two ends of the two non-woven fabrics extend to the upper part 22 of the waist circumference together, and when reaching the position of the upper part 22 of the waist circumference, they are folded for the first time to the inner side of the absorption main body 1. At this time, the two ends of the outer layer waist circumference non-woven fabric 3 are folded, and the ends are respectively placed at the middle position of the waist portion 2. Then, the inner layer waist circumference non-woven fabric 4 continues to extend to the lower part 23 of the waist circumference, and when reaching the position of the lower part 23 of the waist circumference, the inner layer waist circumference non-woven fabric 4 starts to fold for the second time. This folding is a continuous folding twice along the inner side of the absorption main body 1 and forms a clear folding structure. Through the two foldings, the inner layer waist circumference non-woven fabric 4 forms the second leakage prevention pocket 24 and the extension layer 241 at the lower part 23 of the waist circumference in sequence. The extension layer 241 cooperates with the inner layer waist circumference non-woven fabric 4 on the side close to the absorption main body 1 to form a leakage prevention pocket, and the second leakage prevention pocket 24 cooperates with the leakage prevention pocket to form a double pocket structure. The second leakage prevention pocket 24, the extension layer 241 and the outer layer waist circumference non-woven fabric 3 cooperate with each other to form the second folding structure of the waist portion 2.

[0042] It should be noted that the height of the second leakage prevention pocket 24 and the extension layer 241 can be adjusted according to the requirements. By adjusting the folding height of the inner layer waist circumference non-woven fabric 4 at the lower part 23 of the waist circumference, the second leakage prevention pocket 24 and the extension layer 241 with different heights or the same height can be formed. The height of the end of the extension layer 241 can be higher or lower than the height of the opening of the second leakage prevention pocket 24.

[0043] As shown in Figure 3As shown, as an improved way of the above embodiment, the second leakage-proof pocket 24 is provided with a plurality of third elastic spandex filaments 7 equidistantly arranged along the height direction of the second leakage-proof pocket 24 between the two layers of inner waist circumference non-woven fabrics 4 away from the side of the absorbent body 1.

[0044] Through the longitudinal elastic contraction characteristics of the third elastic spandex filaments 7, the pocket opening part of the second leakage-proof pocket 24 forms a circumferentially distributed three-dimensional wrinkle structure, realizing a dynamic tightening effect, thereby establishing a primary leakage-proof barrier at the front and rear ends of the absorbent article, and the extension layer 241 cooperates with the inner waist circumference non-woven fabric 4 close to the side of the absorbent body 1 to form a leakage-proof pocket, which can serve as a secondary buffer structure for preventing leakage, and when the leakage-proof function of the second leakage-proof pocket 24 is saturated, it can implement secondary interception of overflow excrement through the second leakage-proof pocket 24, thereby ensuring the reliability of the leakage-proof of the absorbent article, on the other hand, the extension layer 241 has a flexible deformation capability, which can always be in close contact with the user's waist and abdomen during wearing, and to a certain extent, it can reduce the pressure directly applied by the first elastic spandex filaments 5 on the skin of the waist and abdomen, thereby allowing the user to obtain a good wearing experience.

[0045] As shown in the drawings, Figure 4 As one of the preferred embodiments of the present application, the inner waist circumference non-woven fabric 4 is folded three times in succession at the lower part of the waist circumference 23 to the inside of the absorbent body 1, and the third leakage-proof pocket 25 and the fourth leakage-proof pocket 26 are formed respectively.

[0046] In another waist circumference part 2 structure of the absorbent article of the present application, the third leakage-proof pocket 25 and the fourth leakage-proof pocket 26 are formed by folding the inner waist circumference non-woven fabric 4 three times at the lower part of the waist circumference 23, and the specific process is as follows:

[0047] Firstly, the inner waist circumference nonwoven fabric 4 and the outer waist circumference nonwoven fabric 3 are sequentially arranged outside the absorbent body 1, the two ends of the two layers of nonwoven fabrics extend to the waist circumference upper portion 22 together, and when reaching the position of the waist circumference upper portion 22, the two ends of the outer waist circumference nonwoven fabric 3 are folded for the first time to the inside of the absorbent body 1, at this time, the two ends of the outer waist circumference nonwoven fabric 3 are placed at the middle position of the waist circumference portion 2 after being folded, then the inner waist circumference nonwoven fabric 4 continues to extend to the waist circumference lower portion 23, and when reaching the position of the waist circumference lower portion 23, the inner waist circumference nonwoven fabric 4 starts to be folded for the second time, this folding is a continuous three-time folding in the direction of the inside of the absorbent body 1 and forms a clear folding structure, through the three-time folding, the inner waist circumference nonwoven fabric 4 sequentially forms the third leakage-proof pocket 25 and the fourth leakage-proof pocket 26 at the waist circumference lower portion 23, and at the same time, the two ends of the inner waist circumference nonwoven fabric 4 are placed at the middle position inside the waist circumference portion 2 after being folded for the three times in the direction of the inside of the absorbent body 1 at the waist circumference lower portion 23, and cooperate with the outer waist circumference nonwoven fabric 3 to form the third folding structure of the waist circumference portion 2. Such folding mode not only enhances the front and rear leakage-proof effect of the absorbent article, but also ensures that the waist circumference portion 2 has good fit and support.

[0048] It should be noted that the heights of the third leakage-proof pocket 25 and the fourth leakage-proof pocket 26 can be adjusted according to requirements, and different heights or the same height of the third leakage-proof pocket 25 and the fourth leakage-proof pocket 26 are formed by adjusting the folding height of the inner waist circumference nonwoven fabric 4 at the waist circumference lower portion 23.

[0049] As shown in FIG. 1, the third leakage-proof pocket 25 and the fourth leakage-proof pocket 26 are arranged at the waist circumference lower portion 23 of the absorbent article, and the two ends of the inner waist circumference nonwoven fabric 4 of the third leakage-proof pocket 25 and the fourth leakage-proof pocket 26 are placed at the middle position inside the waist circumference portion 2. Figure 4 As shown in FIG. 2, as an improved mode of the above embodiment, in the structure of the present absorbent article, a plurality of fourth elastic spandex filaments 8 are arranged equidistantly along the height direction of the third leakage-proof pocket 25 between the two layers of inner waist circumference nonwoven fabrics 4 away from the side of the absorbent body 1, and no fourth elastic spandex filaments 8 are arranged between the two layers of inner waist circumference nonwoven fabrics 4 away from the side of the absorbent body 1 of the fourth leakage-proof pocket 26.

[0050] Through the longitudinal elastic contraction characteristics of the fourth elastic spandex filaments 8, the pocket opening portion of the third leakage-proof pocket 25 forms a circumferentially distributed three-dimensional wrinkle structure, realizes a dynamic tightening effect, thereby establishing a primary leakage-proof barrier at the front and rear ends of the absorbent article, and the fourth leakage-proof pocket 26 serves as a secondary buffer structure. No fourth elastic spandex filaments 8 are arranged between the two layers of inner waist circumference nonwoven fabrics 4 away from the side of the absorbent body 1 of the fourth leakage-proof pocket 26, so that this region maintains the ability of flexible deformation, and when the leakage-proof function of the third leakage-proof pocket 25 is saturated, the third leakage-proof pocket 25 can implement secondary interception of overflow excrement, and such double leakage-proof mode further ensures the reliability of the leakage-proof of the absorbent article.

[0051] As shown in FIG. 3, as an improved mode of the above embodiment, in the structure of the present absorbent article, a plurality of fourth elastic spandex filaments 8 are arranged equidistantly along the height direction of the third leakage-proof pocket 25 between the two layers of inner waist circumference nonwoven fabrics 4 away from the side of the absorbent body 1, and no fourth elastic spandex filaments 8 are arranged between the two layers of inner waist circumference nonwoven fabrics 4 away from the side of the absorbent body 1 of the fourth leakage-proof pocket 26. Figure 5As shown, as another improvement of the above embodiment, in the structure of this absorbent product, fourth elastic spandex filaments 8 are provided between the two inner layers of nonwoven fabric 4 of the third leak-proof pocket 25 and the fourth leak-proof pocket 26, and between the two inner layers of nonwoven fabric 4 of the fourth leak-proof pocket 26 on the side away from the absorbent body 1. These filaments are arranged at equal intervals along the height direction of the fourth leak-proof pocket 26.

[0052] The addition of the fourth elastic spandex filament 8 allows the third leak-proof pocket 25 and the fourth leak-proof pocket 26 to maintain a more three-dimensional shape in the structure of the absorbent product. The third leak-proof pocket 25 and the fourth leak-proof pocket 26 utilize the good elasticity of the fourth elastic spandex filament 8 to establish a double-reinforced leak-proof structure, which helps the third leak-proof pocket 25 and the fourth leak-proof pocket 26 to better fit the user's waist and abdomen, thereby improving leak-proof performance and wearing comfort. In addition, the two inner layers of waistband non-woven fabric 4 between the fourth elastic spandex filament 8 and the third leak-proof pocket 25 and the fourth leak-proof pocket 26, and the two inner layers of waistband non-woven fabric 4 on the side of the fourth leak-proof pocket 26 away from the absorbent body 1, provide additional support for the leak-proof pockets, helping to maintain the shape stability of the third leak-proof pocket 25 and the fourth leak-proof pocket 26 and prevent deformation due to external forces during use.

[0053] like Figure 1 As shown, in one of the preferred embodiments of this utility model, the absorbent body 1 includes a surface layer 11, a flow guiding layer 12, an absorbent core 13, and a leak-proof and breathable PE film layer 14 arranged sequentially from the inside to the outside. The two ends of the surface layer 11, the flow guiding layer 12, and the leak-proof and breathable PE film layer 14 of the absorbent body 1 extend towards the lower waist 23 and are placed between the leak-proof pocket of the lower waist 23 and the inner waist non-woven fabric 4 on the outside of the waist 2.

[0054] Liquid quickly permeates the surface layer 11 of the absorbent body 1, and the flow guiding layer 12 laterally diffuses the liquid to the absorbent core 13 for storage. The leak-proof and breathable PE membrane layer 14 serves as the final barrier to prevent reverse permeation. The two ends of the surface layer 11, the flow guiding layer 12, and the leak-proof and breathable PE membrane layer 14 extend to the space between the leak-proof pocket and the inner waistband nonwoven fabric 4, respectively. The leak-proof and breathable PE membrane layer 14 of the absorbent body 1 is bonded to the inner waistband nonwoven fabric 4, thereby enabling the absorbent body 1 to be stably fixed on the inner waistband nonwoven fabric 4, which helps to enhance the overall structure and stability of the absorbent product.

[0055] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
