Description

Technical Field

[0001] The utility model relates to the field of sanitary products, in particular to a composite absorbent paper. Background Art

[0002] Absorbent paper can be used to make the absorbent core of diapers. Its main function is to absorb and lock urine. After the baby urinates, the absorbent paper receives the urine and guides it into the absorbent core to ensure that the urine is fully absorbed by the absorbent core.

[0003] The absorbent material in the absorbent core determines the absorption capacity of the absorbent core, while the absorbent paper located on the surface of the absorbent core affects the speed at which the absorbent core absorbs urine. The purpose of the utility model is to improve the absorbent paper structure to improve the absorption efficiency of the absorbent paper on urine. Utility Model Content

[0004] The utility model aims to provide a composite absorbent paper to solve the problems mentioned in the background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: including a main body layer, a top support layer, a bottom support layer and a deformation joint, the two surfaces of the main body layer are respectively provided with guide plates, the guide plates are arranged at equal intervals and adjacent guide plates are parallel to each other, the top support layer is located above the main body layer, the top support layer and the bottom support layer are connected to the guide plates on the top surface of the main body layer, a first opening is provided on the top support layer, the bottom support layer is located below the main body layer, the top surface of the bottom support layer is connected to the guide plates of the bottom support layer of the main body layer, a second opening is provided on the bottom support layer, and the deformation joints are respectively located at the edges of the first opening and the second opening and are connected to the first opening and the second opening.

[0006] In order to optimize the above technical solution, further measures are taken as follows: a lodging seam is formed on the guide plate, and the lodging seam separates the guide plate into a plurality of identical individuals. When the guide plate located in the first opening and the second opening is squeezed, the guide plate can be flattened into a lodging state along the lodging seam, so that the surface of the absorbent paper is concave at the first opening and the second opening, and the surface of the absorbent paper is uneven and staggered.

[0007] As a further improvement to the above technical solution: a plurality of deformation joints are rotationally symmetrically distributed around the first opening and the second opening. The purpose of setting the deformation joints is to improve the deformation capacity of the first opening and the second opening. When squeezed, the top support layer and the bottom support layer can deform along the deformation joints to squeeze the guide plate, causing the guide plate to bend and fall along the falling joints.

[0008] As a further improvement of the technical solution: the orthographic projection of the first opening on the main body layer is not in contact with the orthographic projection of the second opening on the main body layer, so as to avoid the absorbent paper being too thin in this part due to the corresponding positions of the first opening and the second opening.

[0009] As an improvement to the above technical solution: the first opening area is larger than the second opening area. The large first opening area can improve the blocking effect on urine, prolong the flow time of urine on the surface of absorbent paper, and help urine to be absorbed and penetrated by absorbent paper.

[0010] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0011] The utility model provides a composite absorbent paper. By setting a first opening and a second opening, the surface of the absorbent paper is made uneven, which can block urine and prolong the absorption and penetration of urine. In addition, when the absorbent core fully absorbs water and expands, the guide plate can be deformed along the inverted seam, which further aggravates the uneven surface of the absorbent paper, thereby alleviating the discomfort caused by the absorbent core being close to the skin and promoting air flow to relieve stuffiness.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example

[0019] See also Figures 1 - 3 The utility model provides a composite absorbent paper, comprising a main body layer 1, a top support layer 2, a bottom support layer 3 and a deformation seam 4. Guide plates 101 are integrally arranged on both sides of the main body layer 1. The guide plates 101 are arranged at equal intervals and adjacent guide plates 101 are parallel to each other. Inverted seams 102 are formed on the guide plates 101, and the inverted seams 102 separate the guide plates 101 into a plurality of identical individuals.

[0020] The top support layer 2 is located above the main body layer 1 , the bottom support layer 3 of the top support layer 2 is connected to the guide plate 101 on the top surface of the main body layer 1 , and a first opening 201 is opened on the top support layer 2 .

[0021] The bottom support layer 3 is located below the main layer 1, the top surface of the bottom support layer 3 is connected to the guide plate 101 of the bottom support layer 3 of the main layer 1, a second opening 301 is opened on the bottom support layer 3, the orthographic projection of the first opening 201 on the main layer 1 has no contact with the orthographic projection of the second opening 301 on the main layer 1, and the area of ​​the first opening 201 is larger than the area of ​​the second opening 301.

[0022] The deformation joints 4 are respectively located at the edges of the first opening 201 and the second opening 301 and are connected to the first opening 201 and the second opening 301 . The plurality of deformation joints 4 are rotationally symmetrically distributed around the center of the first opening 201 and the second opening 301 .

[0023] Working principle: This product can be used to manufacture the absorbent core of diapers. The top support layer 2 is located outside the absorbent core and the bottom support layer 3 is facing the inside of the absorbent core. The first opening 201 and the second opening 301 opened on the top support layer 2 and the bottom support layer 3 can block the flow of urine and prevent urine from flowing away quickly from the surface of the absorbent paper, which helps to improve the absorbent paper's absorption effect on urine and the penetration efficiency of urine on the absorbent paper.

[0024] When the absorbent core fully absorbs urine, the absorbent core will expand and press against the user's skin. At this time, the guide plate 101 exposed by the first opening 201 on the top support layer 2 will be squeezed by the skin, and the guide plate 101 exposed by the second opening 301 on the bottom support layer 3 will be squeezed by the absorbent material of the absorbent core, so that the guide plate 101 is deformed and pressed down along the inverted seam 102, and the surface of the absorbent paper can be concave at the first opening 201 and the second opening 301, so that the surface of the absorbent paper is uneven with a height difference, which can alleviate the discomfort of the absorbent core being close to the user's skin after the urine is fully absorbed. At the same time, the uneven surface of the absorbent paper can promote airflow and alleviate the stuffy discomfort. In addition, the staggered surface of the absorbent paper can also have a blocking effect on urine to prevent urine from flowing freely.
