Description

Technical Field

[0001] This utility model relates to the field of diaper technology, specifically to a dry, ultra-thin diaper composite core. Background Technology

[0002] Dry, ultra-thin diapers typically weigh between 0.5 and 4.5 grams. These diapers use special materials such as bamboo charcoal and carbon black to improve absorbency and breathability. They also feature soft fabrics and a thin coating, making them comfortable, breathable, and suitable for a baby's delicate skin.

[0003] A dry and soft composite core described in the prior art includes, from top to bottom, a top layer, a first absorbent resin layer, a non-woven fabric guide layer, a second absorbent resin layer, and a bottom layer. The top layer is composed of a polyphilic spunbond fabric. The first absorbent resin layer is partially shielded by a baffle during the feeding of the superabsorbent polymer, and the shielded part forms a strip-shaped guide channel. The non-woven fabric guide layer is composed of hydrophilic ES bicomponent fibers and plant fibers.

[0004] While the aforementioned existing technologies can reduce the risk of urination leakage and greatly improve the dryness of the core material, and the core material does not contain wood pulp fiber, which can reduce workshop dust and improve the production environment, the good absorbency can make it difficult for parents to notice when the baby urinates, and they may not be able to change the diaper in time, increasing the possibility of urine causing infection to the baby. Utility Model Content

[0005] The purpose of this invention is to provide a dry, ultra-thin diaper composite core to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A dry, ultra-thin diaper composite core includes a diaper with a composite core on the inner side of the diaper. The composite core consists of a surface layer, a first absorbent resin layer, a second absorbent resin layer, and a wrapping layer. A urine color-changing test strip is provided in the second absorbent resin layer. Both ends of the urine color-changing test strip are bent, and the bent ends of the urine color-changing test strip extend through the wrapping layer to the outside.

[0008] As a preferred embodiment of this utility model, the bent end of the urine color-changing test strip is bonded and fixed to the outer wall of the wrapping layer.

[0009] As a preferred embodiment of this utility model, the surface layer is bonded to the first absorbent resin layer by hot melt adhesive, the first absorbent resin layer is bonded to the second absorbent resin layer by hot melt adhesive, and the second absorbent resin layer is bonded to the wrapping layer by hot melt adhesive.

[0010] As a preferred embodiment of this utility model, the composite core is provided with a funnel at its center, and the reset core at the funnel is folded.

[0011] As a preferred embodiment of this utility model, one end of the diaper is integrally provided with an adhesive strip, and the outer wall of the other end of the diaper is provided with an adhesive strip, and the adhesive strip is bonded to the adhesive strip.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In response to the problems raised in the background art, this application adds urine color-changing test strips to the composite core. After the baby urinates, the urine comes into contact with the test strip and causes it to change color. Parents can understand the baby's defecation status through the externally attached test strips, reminding parents to change diapers in time and avoid urine causing infection to the baby.

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the embodiments of this utility model.

[0018] Example

[0019] Please see Figure 1-3 This utility model provides a technical solution:

[0020] A dry, ultra-thin diaper composite core includes a diaper 1. The inner side of the diaper 1 has a composite core 2. The composite core 2 consists of a surface layer 201, a first absorbent resin layer 202, a second absorbent resin layer 203, and a wrapping layer 204. A urine color-changing test strip 2031 is disposed within the second absorbent resin layer 203. Both ends of the urine color-changing test strip 2031 are bent, and the bent ends of the urine color-changing test strip 2031 extend through the wrapping layer 204 to the outside. The bent ends of the urine color-changing test strip 2031 are connected to the wrapping layer 204. The outer wall is bonded and fixed. The surface layer 201 is bonded to the first absorbent resin layer 202 by hot melt adhesive. The first absorbent resin layer 202 is bonded to the second absorbent resin layer 203 by hot melt adhesive. The second absorbent resin layer 203 is bonded to the wrapping layer 204 by hot melt adhesive. A leak pocket 5 is provided at the center of the composite core 2. The core 2 at the leak pocket 5 is folded. One end of the diaper 1 is integrally provided with an adhesive strip 3. The outer wall of the other end of the diaper 1 is provided with an adhesive strip 4. The adhesive strip 3 and the adhesive strip 4 are bonded together.

[0021] When in use, the adhesive tape 3 is attached to the adhesive strip 4, so that the diaper is worn on the baby. When the baby urinates, the urine penetrates the surface layer 201 and is absorbed by the first absorbent resin layer 202 and the second absorbent resin layer 203. The two absorbent resin layers can increase the absorption capacity and absorption speed, and prevent leakage. At the same time, after the first absorbent resin layer 202 and the second absorbent resin layer 203 absorb the urine, the absorbed urine will come into contact with the urine color-changing test strip 2031. When the urine color-changing test strip 2031 comes into contact with specific chemicals in the urine, it will change color. Parents can understand the baby's defecation status through the end of the urine color-changing test strip 2031 on the outside of the diaper 1. The changing color can remind parents to change the diaper in time to avoid urine causing infection to the baby. In addition, the leak pocket 5 can catch the baby's excrement and unfold it, thereby reducing the situation of excrement contacting the skin.

[0022] The working process of this utility model is as follows: When in use, the adhesive tape 3 is attached to the adhesive strip 4, so that the diaper is worn on the baby. When the baby urinates, the urine penetrates the surface layer 201 and is absorbed by the first absorbent resin layer 202 and the second absorbent resin layer 203. The two absorbent resin layers can increase the absorption capacity and absorption speed, and prevent leakage. At the same time, after the first absorbent resin layer 202 and the second absorbent resin layer 203 absorb the urine, the absorbed urine will come into contact with the urine color-changing test strip 2031. When the urine color-changing test strip 2031 comes into contact with specific chemical substances in the urine, it will change color. Parents can understand the baby's defecation status and change the diaper by looking at the end of the urine color-changing test strip 2031 on the outside of the diaper 1.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
