Description

Technical Field

[0001] The utility model relates to the technical field of absorbent products, in particular to an absorbent product with a back pocket leakage prevention function. 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] Traditional diapers usually lack structural features that hinder the movement of feces. In particular, in some existing products, in order to prevent the user's waist from being strongly squeezed, a waist structure with less pressure is usually adopted. Therefore, feces may travel to the outside of the diaper, such as flowing out through the rear waist opening. The excrement moving close to the wearer's skin at the waist may also cause problems, which will make it more difficult to clean the wearer's skin and increase the chance of irritation to the wearer's skin.

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.

[0024] like Figure 1 As shown, an absorbent product with a back pocket leakage prevention function 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 comprises a waist inner layer 21 and a waist outer layer 22, the waist inner layer 21 and the waist outer layer 22 are formed by integrally folding non-woven fabrics to form a hollow interlayer 4, and a bonding area is provided at the end of the hollow interlayer 4 in the length direction;

[0025] like Figure 1 and Figure 2 As shown, further, in the above scheme, an absorbent structure 3 extending along the length direction of the main body 1 is provided in the middle part of the main body 1, and leak-proof partition edges 6 are provided on both sides of the absorbent structure 3, and the ends of the leak-proof partition edges 6 in the length direction are clamped between the waist inner layer 21 and the waist outer layer 22, and extend to the bonding area in the hollow interlayer 4.

[0026] like Figure 1 , Figure 2 and Figure 5 As shown, the utility model has a waist structure 2, the main body 1 is composed of an absorbent structure 3 and a waist structure 2, the waist structure 2 is formed by a non-woven fabric folded in an inverted U shape to form a waist inner layer 21, a waist inner layer 21 and a hollow interlayer 4, and a first bonding area 42 and a second bonding area 43 are provided at both ends of the hollow interlayer 4 in the length direction, thereby forming the second leak-proof cavity 41 in the middle position of the hollow interlayer 4, the second leak-proof cavity 41 is aligned with the end of the absorbent structure 3, and the end portion of the absorbent structure 3 extends into the second leak-proof cavity 41.

[0027] 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.

[0028] The hollow interlayer 4 is provided with a pocket cloth 7 near the end of the absorbent structure 3 , and the end of the pocket cloth 7 in the length direction is bonded and fixed to the leak-proof partition 6 , thereby forming a first leak-proof cavity 5 between the pocket cloth 7 and the absorbent structure 3 .

[0029] like Figure 1 , Figure 4 and Figure 6 As shown, further, in the first embodiment of the utility model, a pocket cloth 7 is sandwiched at the end position of the hollow interlayer 4 corresponding to the absorbent structure 3, and the pocket cloth 7 protects the user's epidermis and guides the excrement to prevent the excrement from leaking out between the waist inner layer 21 and the human body surface. Specifically, the end of the pocket cloth 7 in the length direction is bonded to the inner side of the leak-proof partition 6 or other forms of tightly composite fixation, and the side edge of the pocket cloth 7 in the width direction extends inward along the opening of the second leak-proof cavity 41. When in use, the leak-proof partition 6 stands upright, driving the side edge of the pocket cloth 7 toward the absorbent structure 3 to be open, which is conducive to the excrement entering the first leak-proof cavity 5 along the gap between the pocket cloth 7 and the surface of the absorbent structure 3, and has the function of preventing back leakage.

[0030] Furthermore, in the second embodiment, the end of the pocket cloth 7 in the length direction is bonded to the inner side of the leak-proof partition 6 or is tightly fixed in other forms. Under the contraction of the elastic band at the waist, the pocket cloth 7 is wrinkled and blocked at the rear end of the absorbent structure 3. When back leakage occurs, the wrinkled pocket cloth 7 has a blocking effect on the excrement leaking from the back. In this scheme, it is possible to consider providing an elastic band on one side edge of the pocket cloth 7 near the end of the length direction of the absorbent structure 3, which can increase the degree of bulge of the wrinkled cavity formed by the contraction of the elastic band of the pocket cloth 7 and the degree of fit with the user's skin, thereby making the blocking effect of the pocket cloth 7 better.

[0031] Furthermore, in the third embodiment, a pocket cloth 7 is sandwiched at the end position of the hollow interlayer 4 corresponding to the absorbent structure 3, and the end of the pocket cloth 7 in the length direction is bonded to the inner side of the leak-proof partition 6 or otherwise tightly compounded and fixed, and the side edge of the pocket cloth 7 in the width direction extends inward along the opening of the second leak-proof cavity 41 and is bonded to the end face of the absorbent structure 3 or otherwise tightly compounded and fixed, to form a first layer of anti-rear leakage structure, and the second leak-proof cavity 41 is a second layer of anti-rear leakage structure. Specifically, the front end of the pocket cloth 7 is bonded to the absorbent structure 3 or otherwise tightly compounded and fixed, and the two sides are bonded to the leak-proof partition 6 or otherwise tightly compounded and fixed, to form a first layer of anti-rear leakage structure that is sealed on three sides when in use. When rear leakage occurs, the pocket cloth 7 blocks the excrement, and when the excrement leaks backward along the pocket cloth 7, it enters the second leak-proof cavity 41 through the opening of the second leak-proof cavity 41. The anti-rear leakage structure has a double leak-proof effect.

[0032] like Figure 4 , Figure 5 and Figure 6 As shown, further, in the above scheme, the width dimension of the waist inner layer 21 is smaller than the width dimension of the waist outer layer 22, and the first bonding area 42 and the second bonding area 43 are respectively provided at both ends of the waist inner layer 21 and the waist outer layer 22, and the leakage-proof cavity 41 is formed between the first bonding area 42 and the second bonding area 43. After the two sides of the inverted U-shaped second leakage-proof cavity 41 are sealed by the first bonding area 42 and the second bonding area 43 respectively, the second leakage-proof cavity forms an opening toward one side of the absorbent structure 3 for collecting the excrement leaked afterwards.

[0033] Specifically, the end of the absorbent structure 3 extends into the second leak-proof cavity 41 along one side of the opening of the second leak-proof cavity 41 , and the width of both sides of the absorbent structure 3 in the length direction does not exceed the inner sides of the first bonding area 42 and the second bonding area 43 .

[0035] Furthermore, in the above scheme, the side edge of the pocket cloth 7 in the width direction extends inwardly along the opening of the second anti-leakage cavity 41 and is bonded to the end surface of the absorbent structure 3 or fixed in a tightly composite manner in other forms.

[0036] Furthermore, in the above scheme, the side edge of the pocket cloth 7 in the width direction extends inward along the opening of the second leakage-proof cavity 41 to no more than the end of the absorbent structure 3 in the length direction or is retracted by at least 5 mm toward the center of the absorbent structure 3, and the front end of the leakage-proof partition edge 6 does not exceed the end of the absorbent structure 3, ensuring that the blocking pocket-shaped structure formed between the pocket cloth 7 and the leakage-proof partition edge 6 can confine the excrement to the area of ​​the absorbent structure 3 with absorption performance.

[0037] like Figure 3 As shown, further, in the above scheme, a plurality of sub-adhesive areas 44 extending along the width direction are provided in the second leakage-proof cavity 41, and the sub-adhesive areas 44 are arranged at equal intervals along the length direction of the second leakage-proof cavity 41, and a sub-leakage-proof cavity 45 is formed between two adjacent sub-adhesive areas 44. The second leakage-proof cavity 41 is formed by bonding a plurality of sub-adhesive areas 44 to form a plurality of sub-leakage-proof cavities 45, and the sub-leakage-proof cavity 45 has the same anti-backward leakage function as the second leakage-proof cavity 41 in the above embodiment.

[0038] Furthermore, in the above scheme, a first elastic rubber band 63 of one or more is provided at the connection position between the first leak-proof partition 61 and the absorbent structure 3, and a second elastic rubber band 64 of one or more is provided at the connection position between the second leak-proof partition 62 and the absorbent structure 3, and the ends of the first elastic rubber band 63 and the second elastic rubber band 64 are aligned with the ends of the absorbent structure 3.

[0039] 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.
