Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of absorbent products, in particular to an absorbent product with a rear pocket moisture absorption and leakage prevention structure. Background Art
[0002] Diapers are an important and indispensable product in daily life care. Their main function is to absorb and retain human excrement. At the same time, diapers prevent the excrement from leaking from the absorbent product, thereby preventing the excrement from soiling or contaminating the wearer's or caregiver's clothing, or other products such as bedding that may come into contact with the wearer.
[0003] The most common form of rear leakage of diapers is that the exudate leaks from the rear waist area of the absorbent product, and the exudate with a higher water content moves toward the rear waist position in the absorbent product close to the wearer's skin, making it easier to detect leakage. This situation may occur more often with semi-solid feces such as low-viscosity feces (such feces may be common for young children). Under the influence of gravity, movement, force and the pressure of the wearer of the absorbent product, such exudate cannot be effectively prevented by the ordinary diaper's anti-rear leakage structure.

[0006] As an improvement of the above solution, the ends of the absorbent core and the leak-proof partition extend into the hollow interlayer, the ends of the leak-proof partition are fixed to the bonding area, and the ends of the absorbent core extend into the leak-proof cavity.

[0008] As an improvement of the above solution, one side of the absorbent body in the width direction extends toward the inner side of the hollow interlayer, and the other side of the absorbent body in the width direction extends along the opening of the leakage-proof cavity toward the middle of the absorbent core.
[0009] As an improvement of the above scheme, the width dimension of the inner layer is smaller than the width dimension of the outer layer, and the bonding area includes a first bonding area and a second bonding area. The first bonding area and the second bonding area are respectively bonded and fixed to the ends of the hollow interlayer in the length direction to form a leakage-proof cavity with an opening toward the end of the absorbent core.
[0010] As an improvement of the above scheme, the leak-proof edge includes a first leak-proof edge and a second leak-proof edge respectively arranged on both sides of the width direction of the absorbent core, and the ends of the first leak-proof edge and the second leak-proof edge do not exceed the ends of the absorbent core in the length direction.

[0012] As an improvement of the above solution, at least one elastic band extending along the length direction of the hollow interlayer is sandwiched in the direction of the hollow interlayer close to the end of the absorbent core.
[0013] The utility model has the beneficial effect that: the waist structure is formed by folding the non-woven fabric, and the two ends are closed by the bonding area, so that the waist structure forms a leak-proof cavity at one end corresponding to the length direction of the absorbent structure, which effectively prevents the outflow from leaking from the rear waist of the diaper, and by arranging an absorbent body at the opening of the leak-proof cavity, it can absorb urine and moisture in the excrement, reduce the moisture and viscosity in the excrement, reduce the fluidity of the excrement, and can be more effectively blocked by the leak-proof cavity to prevent leakage from the rear.

DETAILED DESCRIPTION
[0021] The implementation methods of the present invention are described below in conjunction with the accompanying drawings and relevant embodiments. The implementation methods of the present invention are not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as common knowledge in this technical field and can be known and mastered by technical personnel in this technical field.
[0022] like Figure 1 , Figure 2 and Figure 3 As shown, an absorbent product with a back pocket moisture absorption and leakage-proof structure comprises a main body 1 and a waist structure 2 arranged at the end of the main body 1 in the length direction, the waist structure 2 is formed by folding a non-woven fabric in an inverted U shape, the waist structure 2 comprises an inner layer 201 facing the human body and an outer layer 202 away from the human body, a hollow interlayer 203 is formed between the inner layer 201 and the outer layer 202, an adhesive area 3 is provided at the end of the hollow interlayer 203 in the length direction, so that a leakage-proof cavity 204 is formed in the middle position of the hollow interlayer 203, the main body 1 comprises an absorbent core 4 and leakage-proof partition edges arranged on both sides of the absorbent core 4, an absorbent body 7 is provided at the opening of the leakage-proof cavity 204 corresponding to the end of the absorbent core 4, the absorbent body 7 is sandwiched between the inner layer 201 and the end face of the absorbent core 4, and the two ends of the absorbent body 7 in the length direction are respectively compounded with the inner sides of the leakage-proof partition edges on both sides to form a barrier in the front-back direction of the main body 1.
[0023] like Figure 1 and Figure 3As shown, the utility model has a waist structure 2, and the waist structure 2 is formed by folding a single non-woven fabric or multiple stacked non-woven fabrics into one piece, the upper end of the waist structure 2 is a closed end, and the end and the lower end of the waist structure 2 in the length direction are open ends, the ends of the waist structure 2 in the length direction are closed by the first bonding area 301 and the second bonding area 302, and a leak-proof cavity 204 is formed in the middle of the waist structure 2 with an opening toward the absorbent core 4. When in use, the leak-proof cavity 204 has the function of preventing excrement from leaking backwards. When the excrement moves along the absorbent core 4 toward the back waist position, it enters the leak-proof cavity 204 through the opening of the leak-proof cavity 204 to avoid leakage along the gap between the waist structure 2 and the human body.
[0024] like Figure 1 , Figure 2 and Figure 3 As shown, further, at least one absorbent body 7 is provided at the opening of the leakproof cavity 204, and the absorbent body 7 is composed of one or more of a sponge block, water-absorbing particles or a composite water-absorbing material. The absorbent body 7 is bonded or tightly compositely fixed to the end surface of the inner layer 201 facing the outer layer 202 or any end of the end surface of the absorbent core 4 or a position where the end is retracted 5 mm or more, and the two ends in the length direction are respectively composited with the inner side surfaces of the leakproof partition edges on both sides of the width direction of the main body 1 to form a length direction of the main body 1. For upward blocking, the length dimension of the absorbent body 7 does not exceed the length dimension of the opening of the leak-proof cavity 204. When excrement with a high water content moves toward the rear waistline through the absorbent core 4, the absorbent body 7 and the leak-proof partition edge form a pocket-like structure to play a blocking role. At the same time, the absorbent body 7 will absorb part of the water, reduce the water content and viscosity in the excrement, and reduce the fluidity of the excrement. When rear leakage occurs through the absorbent body 7, it can be more effectively blocked by the leak-proof cavity 204 to avoid backflow.
[0025] like Figure 6 As shown, further, in one of the schemes, the hollow interlayer 203 is sandwiched with at least one elastic band 8 extending along the length direction of the hollow interlayer 203 near the end of the absorbent structure 3, and the elastic band 8 is adhesively fixed to the end surface of the inner layer 201 facing the outer layer 202, and close to the opening position of the leakage-proof cavity 204. When in use, the elastic band 8 adheres the inner layer 201 to the surface of the human body through its own elastic force, and controls the opening of the leakage-proof cavity 204 to be in an open state.
[0026] Furthermore, in the above scheme, the ends of the absorbent core 4 and the leak-proof partition edge both extend into the hollow interlayer 203, the ends of the leak-proof partition edge are fixed to the bonding area 3, and the ends of the absorbent core 4 extend into the leak-proof cavity 204. When the excrement moves toward the rear waistline, the leak-proof partition edge can prevent the excrement from spreading to both sides to form side leakage. The leak-proof partition edge is in an upright state when in use, and can prop the opening of the leak-proof cavity 204 toward the human body to avoid the opening of the leak-proof cavity 204 from closing, resulting in the inability to effectively block the rear leakage phenomenon.
[0027] It should be noted that one side edge of the absorbent body 7 in the width direction extends toward the inner side of the hollow interlayer 203, and the other side edge of the absorbent body 7 in the width direction extends along the opening of the anti-leakage cavity 204 toward the middle of the absorbent core 4. Specifically, in one embodiment, one side edge of the absorbent body 7 extends toward the inner side of the hollow interlayer 203, and the farthest end does not exceed the bending position of the inner layer 201 and the outer layer 202.
[0028] Further, if Figure 1 and Figure 2 As shown, in the first embodiment of the utility model, the absorbent body 7 is flush with any end of the end surface of the absorbent core 4 in the length direction or is bonded or tightly compositely fixed at a position retracted 5 mm or more from the end (not shown in the figure), and the absorbent body 7 is composed of at least one sponge block, water-absorbing particles or composite water-absorbing material. The ends of the absorbent body 7 in the length direction are aligned with the two sides of the opening of the leak-proof cavity 204. The absorbent body 7 is composed of a single sponge block, water-absorbing particles or composite water-absorbing material with a length equal to the opening size of the leak-proof cavity 204, or is composed of a plurality of sponge blocks, water-absorbing particles or composite water-absorbing materials arranged in sequence along the length direction of the opening of the leak-proof cavity 204.
[0029] like Figure 4As shown, further, in the second embodiment of the present invention, the absorbent body 7 is bonded or tightly composited and fixed to the end of the absorbent core 4 or the position where the end is retracted 5 mm or more, and the material is the same as the previous embodiment. The absorbent body 7 is C-shaped and the opening is facing the middle of the absorbent core 4. Specifically, the two ends of the absorbent body 7 in the length direction can extend along the leak-proof partition edge toward the middle of the absorbent core 4 and exceed the position where the opening of the leak-proof cavity 204 is located, and are exposed on the surface of the absorbent core 4 (not shown in the figure). Under the action of the elastic band of the elastic leak-proof partition edge, a semi-enclosed pocket structure is formed. When the excrement moves toward the rear waistline, it will be blocked by the absorbent body 7, gathered and then the moisture in the excrement will be absorbed, thereby reducing the moisture and viscosity in the excrement, so that it will not continue to penetrate toward the waist, reducing the fluidity of the excrement, and when the back leakage occurs through the absorbent body 7, it can be more effectively blocked by the leak-proof cavity 204 to avoid backflow.
[0030] like Figure 5 As shown, further, in the third embodiment of the present utility model, the absorbent body 7 is bonded or tightly compounded and fixed to the end of the absorbent core 4 or the position where the end is retracted 5 mm or more. The shape of the absorbent body 7 is wavy parallel to the width direction of the absorbent core 4, and is arranged in the leak-proof cavity 204 along the length direction of the absorbent core 4. The material is the same as the previous embodiment. When the excrement moves toward the rear waistline, it will be blocked by the absorbent body 7 and the moisture in the excrement will be absorbed. The wavy shape can effectively retain the excrement on the absorbent body 7, reduce the moisture and viscosity in the excrement, and reduce the fluidity of the excrement. When rear leakage occurs through the absorbent body 7, it can be more effectively blocked by the leak-proof cavity 204.
[0031] It should be noted that the waist structure 2 is applicable to the front and rear ends of the main body 1, and can achieve a good leak-proof effect. Preferably, the embodiments listed in this application are not limited to the use of the waist structure 2 in the rear waist.
[0032] It should be noted that, preferably, the absorbent body 7 is bonded and fixed to the end surface of the inner layer 201 facing the outer layer 202, so that a gap is formed between the absorbent body 7 and the absorbent core 4, which facilitates the entry of excrement into the leak-proof cavity 204 and absorbs moisture in the excrement. In another embodiment, the absorbent body 7 is bonded and fixed to the end surface of the absorbent core 4 facing the inner layer 201, and a gap is formed between the absorbent body 7 and the inner layer 201, so that it is difficult for excrement to enter the leak-proof cavity 204, but the moisture in the excrement will be fully absorbed by the absorbent body 7, and the moisture absorption effect is better than the fixed structure of bonding the absorbent body 7 to the inner layer 201.
[0033] Furthermore, in the above scheme, the width dimension of the inner layer 201 is smaller than the width dimension of the outer layer 202, and the bonding area 3 includes a first bonding area 301 and a second bonding area 302, and the first bonding area 301 and the second bonding area 302 are respectively bonded and fixed to the ends of the hollow interlayer 203 in the length direction to form a leak-proof cavity 204 with an opening toward the end of the absorbent core 4, which is used to receive the excrement that leaks out.
[0034] It should be noted that, preferably, the side edges of the first adhesive area 301 and the second adhesive area 302 are aligned with the side edges of the absorbent core 4 in the width direction, so that it is convenient to guide the excrement to the leak-proof cavity 204 through the absorbent core 4, and at the same time, the absorbent core 4 can absorb part of the liquid retained in the leak-proof cavity 204, thereby reducing the fluidity of the excrement.
[0035] Furthermore, in the above scheme, the leak-proof edge includes a first leak-proof edge 5 and a second leak-proof edge 6 respectively arranged on both sides of the width direction of the absorbent core 4, and the ends of the first leak-proof edge 5 and the second leak-proof edge 6 do not exceed the ends of the absorbent core 4, which refer to the ends in the length direction, and can be retracted toward the middle of the absorbent core 4 by 5 mm or more. The first leak-proof edge 5 and the second leak-proof edge 6 limit the excrement to move only along the length direction of the absorbent core 4 and cannot move to both sides, and during the movement, the moisture in the excrement is reduced through the absorbent core 4, thereby effectively reducing its fluidity.
[0036] Furthermore, in the above scheme, the connecting position between the first leak-proof edge 5 and the absorbent core 4 is provided with one or more first elastic rubber bands 501, and the connecting position between the second leak-proof edge 6 and the absorbent core 4 is provided with one or more second elastic rubber bands 601, and the ends of the first elastic rubber band 501 and the second elastic rubber band 601 are aligned with the end of the absorbent core 4.
[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
