Description

Technical Field

[0001] The utility model relates to the technical field of disposable sanitary products, in particular to baby pull-up pants, adult pull-up pants, sanitary pants and the like, and more particularly to a shorts-type absorbent article. Background Art

[0002] Pants-type absorbent articles generally include an elastic outer body and an absorbent body disposed inside the outer body. The main function of the absorbent body is to absorb and contain human excreta such as urine and feces, thereby bringing a dry feeling to the wearer and preventing the excreta from soiling clothing or contacting other articles. However, when the amount of excreta suddenly increases, the excreta that is not absorbed by the absorbent body, such as some low-viscosity feces of infants and young children, can easily leak from the back waist of the absorbent article through the gap between the outer body and the human skin. In particular, when infants and young children lie on their backs at night, the risk of leakage is more likely to occur at the back waist of the absorbent article. In order to solve the above-mentioned leakage risk problem, the existing technology is to set a leak-proof pocket in the area near the back waist, with the opening of the leak-proof pocket facing the absorbent body. Although this method alleviates the leakage risk of body fluid excretion to a certain extent, since the leak-proof pocket area generally corresponds to the human body's buttocks close to the excretion outlet area, the existing products have insufficient wrapping force in the leak-proof pocket area and the areas on both sides, resulting in poor fit to the wearer, causing the product to sag and fail to effectively absorb body fluid excretion, resulting in leakage in the gap between the outer body and the human skin.

[0003] At the same time, the leak-proof pocket design of existing shorts-type absorbent articles is located far away from the excretion outlet of the human buttocks, and there is also a risk of leakage. Therefore, it is necessary to optimize the position of the leak-proof pocket in a more reasonable way to more effectively absorb human excrement. Utility Model Content

When the shorts-type absorbent article is in an unfolded and stretched state, it has a length direction, a width direction and a thickness direction that are perpendicular to each other.

[0053] When the shorts-type absorbent article is in an unfolded and stretched state, it has a skin side in contact with the human body (wearer) along the thickness direction and a non-skin side away from the skin side, such as Figure 4 , Figure 5 and Figure 7 shown.

[0054] The pants-type absorbent article includes an outer body 20 and an absorbent body 10. The absorbent body 10 is connected to the outer body 20 in the longitudinal direction, and the absorbent body 10 is located on the skin side.

The outer body 20 includes a first sheet 21 provided on the non-skin side, a second sheet 22 provided on the skin side, and a first elastic member 23 arranged between the first sheet 21 and the second sheet 22 in the width direction to form the front waist B1, the abdomen B2, the buttocks B4 and the back waist B5. The absorbent body 10 includes a liquid-permeable sheet, a liquid-impermeable sheet and an absorbent core 11 sandwiched between the liquid-permeable sheet and the liquid-impermeable sheet.

[0059] The first elastic member 23 can be a plurality of elastic spandex yarns in the form of threads (roots), a sheet of elastic film or an elastic non-woven fabric, etc. In this embodiment, the first elastic member 23 is a plurality of spandex yarns, the average dtex of which is 40 dtex to 1200 dtex, and the first elastic member 23 is arranged at equal intervals along the length direction, and the spacing size can be set according to the specific situation. Of course, in other embodiments, the first elastic member 23 can also be arranged at non-equal intervals along the length direction.

[0060] like Figure 1 As shown, the outer body 20 forms arc-shaped leg circumference lines 20a at both sides connected to the absorbent body 10, so that the two leg openings of the formed shorts-type absorbent article can better fit the leg contour of the wearer.

[0061] In the crotch portion B3, the outer body 20 is provided with arc-shaped leg elastic members 26 along the leg lines 20a. The leg elastic members 26 are provided between the first sheet 21 and the second sheet 22. The leg elastic members 26 are thread-like (root-like) elastic spandex yarns.

[0062] like Figure 3 and Figure 4 As shown, according to an embodiment of the present invention, at the buttocks B4 and the back waist B5, the outer body 20 has a bonding area G and a non-bonding area G0 ( Figure 3 The oblique line shadow part is the bonding area), wherein the bonding area G surrounds the non-bonding area G0, such as Figure 3 shown.

[0063] At least at the buttocks B4, the shorts-type absorbent article also has a guard portion 2P extending in the width direction, and the guard portion 2P is located on the side of the absorbent body 10 close to the skin. At least at the buttocks B4, the guard portion 2P is configured with a second elastic member 24 arranged in the width direction, and the second elastic member 24 can be arranged intermittently or continuously. If the second elastic member 24 is arranged intermittently, the second elastic member 24 is at least arranged in the area where the guard portion 2P overlaps with the absorbent body 10. In this embodiment, the second elastic member 24 is arranged continuously. Figure 4 As shown, the second elastic member 24 can be a plurality of elastic spandex yarns in the form of threads (roots), a sheet-shaped elastic film or an elastic non-woven fabric or other elastic materials. In this embodiment, the second elastic member 24 is spandex yarn, and the strand spacing between two adjacent second elastic members 24 is 0.5 mm to 8 mm, preferably 0.5 mm to 5 mm; the average dtex of the plurality of second elastic members 24 is 40 dtex to 800 dtex, preferably, the average dtex is set between 40 dtex and 500 dtex, so as to reduce the feeling of the second elastic member 24 on the skin side of the human body.

[0064] At least at the buttocks B4, the adhesive region G of the outer body 20 is partially bonded and fixed to the protective portion 2P, and the non-bonded region G0 of the outer body 20 overlaps with the unbonded portion of the protective portion 2P in the thickness direction to form a leak-proof bag PO, the opening end of which faces the crotch portion B3, as shown in FIG. Figure 3 and Figure 4 shown.

[0065] The dimension of the leak-proof bag PO along the length direction is not greater than 50 mm. By setting such a dimension, excrement can be more easily sucked into the leak-proof bag PO.

[0066] like Figure 4As shown, in this embodiment, at the rear waist B5, the first sheet 21 has a first extension portion extending beyond the outer body 20 in the length direction. The first extension portion is folded to form a first folded portion 21a, and the first folded portion 21a is folded to form a second folded portion 21b, and the second folded portion 21b is located between the first folded portion 21a and the second sheet 22. Specifically, only from the perspective of the shorts-type absorbent article (regardless of its processing technology), the first extension portion is folded toward one side of the absorbent body 10 to form the first folded portion 21a, and the end of the first folded portion 21a is further folded toward the inner side (the side close to the absorbent body 10) to form the second folded portion 21b. The first folded portion 21a is bonded and fixed to the bonding area G on the side of the outer body 20 close to the skin side by the first adhesive G1, and the second folded portion 21b is bonded and fixed to the first folded portion 21a by the second adhesive G2, and the first folded portion 21a and the second folded portion 21b wrap the second elastic member 24 to form the protective portion 2P.

[0067] Furthermore, the second sheet 22 has an extension portion extending beyond the outer body in the length direction. After the extension portion of the second sheet 22 is folded toward the skin side, it is bonded and fixed to the bonding area G on the skin side of the outer body 20 by the first adhesive G1.

[0068] like Figure 3 and Figure 4 As shown, the protective part 2P along the width direction is bonded and fixed to the bonding area G on the side of the outer body 20 close to the skin by the first adhesive G1, and the non-bonding area G0 of the outer body 20 overlaps with the unbonded part of the protective part 2P along the thickness direction to form a leak-proof bag PO.

[0069] In one embodiment, in order to better prevent leakage, the absorbent body 10 extends into the leak-proof bag PO, and the non-bonded area G0 of the outer body 20, the absorbent body 10 and the unbonded part of the protective part 2P overlap in the thickness direction, such as Figure 4 shown.

[0070] In the present invention, the side edges of the front waist B1 and abdomen B2 along the width direction are respectively sealed with the side edges of the back waist B5 and hips B4 along the width direction to form side sealing parts 30, and the protective part 2P is positioned by the length of the side sealing parts 30.

[0071] like Figure 3 As shown, along the length direction, the side seal portion 30 has an outer end edge 30a near the waist opening, and the side seal portion 30 has an inner end edge 30b near the leg opening. The side seal portion 30 is formed by sealing the side edges of the front waist B1 and abdomen B2 along the width direction with the side edges of the back waist B5 and hips B4 along the width direction, and the length L0 of the side seal portion 30 along the length direction is set.

[0072] At the rear waist B5 and the buttocks B4, a positioning area D is formed by extending along the length direction from the outer end edge 30a of the side seal portion 30 to the inner end edge 30b of the side seal portion 30, and the outer end edge 30a of the side seal portion 30 accounts for 0% of the length L0 of the side seal portion 30, and the inner end edge 30b of the side seal portion 30 accounts for 100% of the length L0 of the side seal portion 30.

[0073] Along the length direction, a portion of the guard portion 2P overlaps with the positioning area D, another portion of the guard portion 2P extends outside the positioning area D, and the portion of the guard portion 2P extending outside the positioning area D is close to the inner edge 30b of the side seal portion 30. Along the length direction, the positioning area D is located within 25% to 60% of the length L0 of the side seal portion 30.

[0074] The utility model positions the protection part 2P by the length of the side sealing part 30 and optimizes the position of the protection part 2P so that the leak-proof bag PO is closer to the excretion area of ​​the wearer's buttocks B4, thereby effectively preventing leakage of excrement.

[0075] like Figure 5 As shown, in one embodiment, at the front waist B1 and the back waist B5 ( Figure 5 The outer body 20 further includes a third sheet 25 , which is located between the first sheet 21 and the second sheet 22 .

[0076] In the front waist portion B1 and the back waist portion B5 , the first elastic member 23 is disposed between the third sheet 25 and the second sheet 22 in the width direction, and a fluffy hollow portion HO is formed between the first sheet 21 and the third sheet 25 .

[0077] Specifically, the first elastic member 23 is arranged between the third sheet 25 and the second sheet 22 in the width direction by hot melt adhesive, heat pressing or ultrasonic wave, etc. The first sheet 21 and the third sheet 25 are not bonded (the first sheet 21 and the third sheet 25 have a hot melt adhesive-free area), so that a fluffy hollow portion HO is formed between the first sheet 21 and the third sheet 25.

[0078] When the shorts-type absorbent article is worn, as the first elastic member 23 expands and contracts, a fluffy hollow portion HO is formed between the first sheet 21 and the third sheet 25, which fits the human skin better and makes the wearer softer and more comfortable.

[0079] Combination Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 7In the present invention, the outer body 20 is provided with a first elastic member 23 extending in the width direction at the front waist B1, the abdomen B2, the buttocks B4 and the back waist B5. At least at the buttocks B4, the guard portion 2P is provided with a second elastic member 24 extending in the width direction.

[0080] like Figure 6 and Figure 7 As shown, at least at the buttocks B4, the outer body 20 has a buttocks reinforcement area 2M, and the buttocks reinforcement area 2M is at least located in the area where the outer body 20 overlaps with the protective part 2P. In this embodiment, along the thickness direction, the buttocks reinforcement area 2M covers the first elastic member 23 of the outer body 20 and the second elastic member 24 of the protective part 2P. The tensile stress in the buttocks reinforcement area 2M along the width direction is greater than the tensile stress in the protective part 2P along the width direction.

[0081] Furthermore, the leg elastic member 26 extends to the buttocks B4. At the buttocks B4, the leg elastic member 26 overlaps with the first elastic component 23, and the buttocks reinforcement area 2M also includes an overlapping area between the leg elastic member 26 and the first elastic component 23.

[0082] like Figure 6 and Figure 7 As shown, at least the back waist portion B5 has a waist opening region 2N. In the thickness direction, the waist opening region 2N covers the first elastic member 23 of the outer body 20. The tensile stress in the buttocks reinforcement region 2M in the width direction is greater than the tensile stress in the waist opening region 2N in the width direction.

[0083] In the utility model, the tensile stress along the width direction of the buttocks reinforcement area 2M is greater than the tensile stress along the width direction of the protective part 2P, and when the buttocks reinforcement area 2M covers the leg elastic component 26 and the first elastic component 23, the tensile stress along the width direction of the buttocks reinforcement area 2M is greater than the tensile stress along the width direction of the outer body 20 in the waist opening area 2N, thereby improving the wrapping force of the leak-proof bag PO and the areas on both sides of the width direction (the excretion area close to the back buttocks of the human body) to provide a good fit to the wearer and prevent the product from sagging due to insufficient wrapping force in the buttocks reinforcement area 2M, so that the leak-proof bag PO cannot effectively absorb human excrement, thereby leaking in the gap between the outer body 20 and the human skin.

[0084] Embodiment 2.

[0085] The difference between this embodiment and the first embodiment is that the formation method of the protection 2P is different.

[0086] like Figure 8As shown, at the rear waist B5, the first sheet 21 has a first extension portion extending beyond the outer body 20 in the length direction. The first extension portion is folded to form a first folded portion 21a, and the first folded portion 21a is folded to form a second folded portion 21b, and the first folded portion 21a is located between the second folded portion 21b and the second sheet 22. Specifically, only from the perspective of the shorts-type absorbent article (regardless of its processing technology), the first extension portion is folded toward one side of the absorbent body 10 to form the first folded portion 21a, and the end of the first folded portion 21a is further folded toward the outside (the side away from the absorbent body 10) to form the second folded portion 21b.

[0087] The first folded portion 21a is bonded and fixed to the bonding area G on the skin side of the outer body 20 by the first adhesive G1, and the second folded portion 21b is bonded and fixed to the first folded portion 21a by the second adhesive G2. The first folded portion 21a and the second folded portion 21b wrap the second elastic member 24 to form the protection portion 2P. The protection portion 2P is set in a desired position relative to the side sealing portion 30.

[0088] Furthermore, the second sheet 22 has an extension portion extending beyond the outer body 20 in the length direction. After the extension portion of the second sheet 22 is folded toward the skin side, it is bonded and fixed to the bonding area G on the skin side of the outer body 20 by the first adhesive G1.

[0089] The other structures of the shorts-type absorbent article of this embodiment are the same as those of the first embodiment and will not be described again here.

[0090] Embodiment three.

[0091] The difference between this embodiment and the first and second embodiments is that the formation method of the protection 2P is different.

[0092] like Fig. 9 As shown, at the rear waist portion B5, the first sheet 21 has a first extension portion extending beyond the outer body in the length direction; and the second sheet 22 has a second extension portion extending beyond the outer body in the length direction.

[0093] The first extension part and the second extension part are folded toward the skin side to form the first folded part 21a and the third folded part 22c respectively. The third folded part 22c is bonded and fixed to the bonding area G on the skin side of the outer body 20 by the first adhesive G1.
