Description

TECHNICAL FIELD

[0001] The utility model relates to absorbent product technical field, specifically disclose a kind of absorbent product of front and rear leakage prevention subassembly setting. BACKGROUND

[0002] In the structural design of traditional absorbent sanitary products (such as baby paper diapers), the anti-leakage function mainly relies on the elastic leakage prevention subassembly arranged in the transverse direction. Specifically, such products usually have a three-dimensional leakage prevention barrier made of high-elasticity material arranged on both sides in the transverse direction. The barrier forms a contact seal with the curve of the human leg through the material's resilience. However, there is a lack of longitudinal sealing structure in current absorbent products, especially at the front and rear ends of the product, where an effective anti-leakage barrier is not established. When the user is in a supine position, a lateral position, or a high-intensity exercise state, the excretions are prone to migrate along the longitudinal direction of the product, which eventually leads to leakage at the edges of the front and rear ends, seriously affecting the product's effectiveness and the wearer's comfort.

[0003] To address the technical defects in longitudinal leakage prevention, existing improvement schemes propose to add an elastic leakage prevention structure at the longitudinal ends of the absorbent body. In the structure of existing absorbent products with front and rear leakage prevention functions, there is a layered structure composed of a skin-friendly surface layer, an anti-leakage bottom film, and an intermediate absorbent body. The original three-dimensional leakage prevention barrier design is maintained in the transverse direction, and elastic waistband assemblies are arranged at both longitudinal ends. The technical features are as follows: the elastic waistband is fixed to the longitudinal edge of the skin-friendly surface layer by hot melt adhesive, and the transverse end of the elastic waistband is sealed and bonded to the longitudinal end of the three-dimensional leakage prevention barrier, forming a longitudinally continuous and closed anti-leakage system. Through the contraction characteristics of the elastic material, this structure aims to establish a dynamic sealing interface at the front and rear ends of the product to block the longitudinal penetration path of excretions.

[0004] Although this technology achieves the construction of a longitudinal leakage prevention structure through the combination of an elastic waistband and adhesive sealing, it still has some deficiencies in practical application. Specifically, due to the limited dynamic fitting ability of the elastic waistband to the human waist and abdomen, which is determined by the material's elasticity and the matching degree of human body movement deformation, when the user changes body position (such as turning over while lying down), the elastic waistband of the existing structure cannot adapt to the changes in skin wrinkles and body surface curvature in real time, which leads to the leakage of excretions through the micro-gap between the waistband and the body surface.

DETAILED DESCRIPTION

[0023] 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.

[0024] In combination Figures 1 to 5 As shown in FIG. 1, an absorbent article provided with front and rear leakage-proof components includes an absorbent body 1 and elastic waistbands 2 arranged at both ends of the absorbent body 1, wherein the elastic waistbands 2 are respectively provided with front and rear leakage-proof components 3 above the absorbent body 1 at both ends, the elastic waistbands 2 include inner and outer non-woven fabrics 21 and 22 arranged in sequence outside the absorbent body 1, the ends of the inner and outer non-woven fabrics 21 and 22 are respectively folded inward on both ends of the absorbent body 1 to form waistband portions 24, the absorbent body 1 is bonded to the inner non-woven fabric 21, the front and rear leakage-proof components 3 are provided with left and right adhesive layers 33 and 34, the end of the leakage-proof non-woven fabric 31 of the left adhesive layer 33 is a first extension end 35, the end of the leakage-proof non-woven fabric 31 of the right adhesive layer 34 is a second extension end 36, the front and rear leakage-proof components 3 include S-shaped folded leakage-proof non-woven fabric 31 and second elastic spandex 32, the second elastic spandex 32 is arranged in the upward folding groove formed by the S-shaped folded leakage-proof non-woven fabric 31 at equal intervals, and the front and rear leakage-proof components 3 are bonded to the inner sides of the waistband portions 24 of the absorbent article and form leakage-proof pockets at both ends of the absorbent body 1.

[0025] Further, in the above structure, first elastic spandex 23 is arranged at equal intervals between the inner and outer non-woven fabrics 21 and 22 of the waistband portions 24 along the height direction of the absorbent body 1.

[0026] It should be noted that, in the above structure, the absorbent body 1 includes a surface layer 11, a flow guide layer 12, an absorbent core 13, and a breathable PE film 14 arranged in sequence from inside to outside.

[0027] The front and rear leakage-proof components 3 are composed of the S-shaped folded leakage-proof non-woven fabric 31 and the second elastic spandex 32, forming a three-dimensional leakage-proof pocket structure, thereby effectively improving the leakage-proof effect, the S-shaped folding increases the number of layers and thickness of the leakage-proof non-woven fabric 31, improving its liquid absorption capacity and blocking capacity, and the addition of the elastic spandex makes the leakage-proof pocket softer and more elastic, better adapting to the body movements of the user, thereby further enhancing the leakage-proof performance.

[0028] In addition, the front and rear leakage-proof components 3 can be prepared separately and then bonded to the front and rear ends of the absorbent article, making the production process more flexible and efficient, and effectively reducing the overall processing difficulty of the absorbent article.

[0029] The first elastic spandex filaments 23 are arranged equidistantly between the inner non-woven fabric 21 and the outer non-woven fabric 22, enhancing the structural stability of the waist circumference part 24, and the elastic waist circumference 2 can maintain good shape and elasticity when subjected to tension or pressure. The first elastic spandex filaments 23 in the elastic waist circumference 2 make the waist circumference part 24 have good elasticity, can adapt to the waist circumference sizes of different users, and stretch and contract with the body movements of the user during use, maintaining close fit. This not only improves the comfort of wearing, but also ensures that the absorbent article is not easily slipped or displaced during use.

[0030] As shown in Figure 2 and Figure 3 As one of the preferred embodiments of the present application, the left adhesive layers 33 of the two sets of front and rear leakage prevention assemblies 3 are respectively bonded to the outer non-woven fabric 22 of the waist circumference part 24 and the part of the surface on the inner side of the upper end of the absorbent body 1 at the upper position of the two ends of the absorbent body 1. The lower part of the left adhesive layer 33 of the front and rear leakage prevention assembly 3 and the end part of the absorbent body 1 form the first leakage prevention pocket 4.

[0031] Further, in the above-mentioned scheme, the first extension end 35 of the front and rear leakage prevention assembly 3 extends upward and is bonded to the outer non-woven fabric 22, and the second extension end 36 is placed on the side of the first leakage prevention pocket 4 away from the absorbent body 1.

[0032] It should be noted that in the above-mentioned embodiments, the height of the second extension end 36 can be higher or lower than the pocket opening position of the first leakage prevention pocket 4.

[0033] It should be noted that the right adhesive layer 34 and the leakage prevention non-woven fabric 31 close to the first leakage prevention pocket 4 can also form a leakage prevention pocket with enhanced leakage prevention effect. When the first leakage prevention pocket 4 is not sufficient to prevent leakage, the right adhesive layer 34 and the leakage prevention non-woven fabric 31 close to the first leakage prevention pocket 4 form a leakage prevention pocket, which can continue to block the excrements.

[0034] The left fit layer 33 of the front and rear leakage prevention assembly 3 is respectively bonded with the outer non-woven fabric 22 of the waistline portion 24 at the upper position of the two ends of the absorbent body 1 and the partial surface of the inner side of the upper end of the absorbent body 1, specifically, the left fit layer 33 is sequentially bonded with the outer non-woven fabric 22 of the inner side of the waistline portion 24, the surface layer 11 of the inner side surface of the two ends of the absorbent body 1 excluding the absorbent core 13 portion from top to bottom, thereby forming a first leakage prevention pocket 4 between the lower side of the left fit layer 33 and the end portion of the absorbent body 1, the pocket structure of the first leakage prevention pocket 4 can effectively capture and block the excretion overflowing from the two ends of the absorbent body 1, prevent further external leakage, the first extension end 35 extends upward and is bonded with the outer non-woven fabric 22, thereby enhancing the structural stability of the first leakage prevention pocket 4, also ensuring the close fit between the first leakage prevention pocket 4 and the outer non-woven fabric 22, reducing the risk of leakage, the second elastic spandex filament 32 makes the first leakage prevention pocket 4 more three-dimensional, thereby enabling the first leakage prevention pocket 4 to better adapt to the body curve and movement of the user.

[0035] When the first leakage prevention pocket 4 is insufficient to completely block the excretion, the right fit layer 34 cooperates with the layer of leakage prevention non-woven fabric 31 close to the side of the first leakage prevention pocket 4, and a leakage prevention pocket with enhanced leakage prevention effect can be formed, and the double leakage prevention structure provides additional leakage prevention capability, further reducing the possibility of leakage.

[0036] As shown in Figure 4 as one of the preferred embodiments of the utility model, the right fit layer 34 of the front and rear leakage prevention assembly 3 is respectively bonded with the outer non-woven fabric 22 of the two ends of the absorbent body 1 and the waistline portion 24, and the second leakage prevention pocket 5 is formed between the right fit layer 34 and the leakage prevention non-woven fabric 31 away from the side of the absorbent body 1.

[0037] Further, in the above structure, the second extension end 36 of the front and rear leakage prevention assembly 3 extends downward and is bonded with the absorbent body 1, and the first extension end 35 is arranged on the side of the second leakage prevention pocket 5 away from the absorbent body 1.

[0038] The right fit layer 34 is respectively bonded with the outer non-woven fabric 22 of the two ends of the absorbent body 1 and the elastic waistline 2, and the second leakage prevention pocket 5 is formed between the right fit layer 34 and the leakage prevention non-woven fabric 31 away from the side of the absorbent body 1, which can effectively capture and block the excretion overflowing from the two ends of the absorbent body 1, prevent further external leakage, thereby improving the leakage prevention performance of the absorbent article.

[0039] The second extension end 36 of the front and rear leakage prevention assembly 3 extends downward and is bonded with the absorbent body 1, the connection strength of the front and rear leakage prevention assembly 3 and the absorbent body 1, and the second elastic spandex filament 32 makes the second leakage prevention pocket 5 formed by the front and rear leakage prevention assembly 3 more three-dimensional and better fit the body curve of the user, thereby improving the reliability of leakage prevention.

[0040] As Figure 5 shown, as one of the preferred embodiments of the present application, the left adhesive layer 33 on the side of the second leakage-proof pocket 5 away from the absorption body 1 extends to the inside of the absorption body 1 and is folded twice in succession, and a third leakage-proof pocket 6 is formed between the two layers of leakage-proof non-woven fabric 31 on the side of the second elastic spandex filament 32 away from the absorption body 1.

[0041] Further, in the above structure, third elastic spandex filaments 37 are arranged equidistantly along the height direction of the third leakage-proof pocket 6 in the area between the leakage-proof non-woven fabric 31 at the position of the left adhesive layer 33 and the leakage-proof non-woven fabric 31 on the side of the third leakage-proof pocket 6 away from the absorption body 1.

[0042] As a further improvement of the above-mentioned second leakage-proof pocket 5, i.e. the left adhesive layer 33 on the side of the second leakage-proof pocket 5 away from the absorption body 1 extends to the inside of the absorption body 1 and is folded twice in succession to form a third leakage-proof pocket 6, the third leakage-proof pocket 6 can increase the number of layers and thickness of the leakage-proof layer, thereby improving the leakage-proof ability of the front and rear ends of the absorption product. When the second leakage-proof pocket 5 may not be able to completely block the excretion, the third leakage-proof pocket 6 as an additional line of defense can effectively capture and block the overflowing excretion, preventing further leakage.

[0043] It should be noted that the height of the second leakage-proof pocket 5 and the third leakage-proof pocket 6 is adjusted according to actual needs, and the folding method of the leakage-proof non-woven fabric 31 is adjusted to obtain different or the same height of the second leakage-proof pocket 5 and the third leakage-proof pocket 6.

[0044] The arrangement of the third elastic spandex filaments 37 enhances the structural stability of the third leakage-proof pocket 6. The third elastic spandex filaments 37 are arranged equidistantly in the area between the leakage-proof non-woven fabric 31 at the position of the left adhesive layer 33 and the leakage-proof non-woven fabric 31 on the side of the third leakage-proof pocket 6 away from the absorption body 1. On the one hand, it can increase the three-dimensionality of the third leakage-proof pocket 6, making it more effective in blocking excretion. On the other hand, it makes the third leakage-proof pocket 6 better fit the body curves of the user, especially in areas prone to leakage such as the waist and hips, providing a more intimate fit and leakage-proof effect.

[0045] As Figure 6 shown, as another scheme for forming the above-mentioned second leakage-proof pocket 5 and third leakage-proof pocket 6, the left adhesive layer 33 on the side of the second leakage-proof pocket 5 away from the absorption body 1 extends to the inside of the absorption body 1 and is folded twice in succession, and a third leakage-proof pocket 6 is formed between the two layers of leakage-proof non-woven fabric 31 on the side of the second elastic spandex filament 32 away from the absorption body 1. Figure 5On the basis of the pocket mode shown in the figure, when the front and rear leakage prevention components 3 are bonded to the outer cover non-woven fabric 22 and the absorbent body 1 of the waist circumference part 24, the right adhesive layer 34 can be directly removed, the front and rear leakage prevention components 3 as a whole present a W shape, thereby forming a new right adhesive layer 34a on one side of the front and rear leakage prevention components 3, and when bonding, the middle and upper sections of the new right adhesive layer 34a are bonded to the outer cover non-woven fabric 22 and the area at both ends of the absorbent body 1 not containing the absorbent core 13, thereby forming a second leakage prevention pocket 5 between the absorbent core 1 and the lower end of the new right adhesive layer 34a, and the third leakage prevention pocket 6 remains in the previous structure.

[0046] Through the above-mentioned simplified scheme, on the basis of maintaining the effect of strengthening leakage prevention through the second leakage prevention pocket 5 and the third leakage prevention pocket 6, the amount of leakage prevention non-woven fabric 31 is reduced, thereby reducing the production cost to a certain extent.

[0047] The above-mentioned is only the preferred embodiment of the present application, it should be pointed out that, for the ordinary skilled in the art, without departing from the principles of the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application.
