Description

Technical Field

[0001] This utility model relates to the field of diaper technology, and in particular to an adult diaper. Background Technology

[0002] Adult diapers are disposable paper-based incontinence products, primarily designed for use by incontinent adults. Their main function is to absorb urine, reducing the burden of caring for incontinent individuals. Key features of these products include high absorbency, comfortable wear, and ease of use. They are typically made of highly absorbent materials that quickly absorb and lock in urine, preventing side and back leaks. Furthermore, adult diapers are designed with wearer comfort in mind, usually featuring an elastic waistband and soft outer materials to ensure comfort even during extended wear.

[0003] Existing disposable diapers can absorb urine, but when there is a lot of urine, it tends to accumulate in the absorbent material. Squeezing can easily force the urine out again, causing backflow. If not changed in time, it can affect the user experience. Utility Model Content

[0004] To address the problem that existing disposable diapers can absorb urine, but when there is a lot of urine, it tends to accumulate in the absorbent material, and squeezing it can easily cause backflow, which can affect the user experience if not changed in time, this application provides an adult disposable diaper, the specific solution of which is as follows.

[0005] An adult diaper includes a main body, wherein an absorbent cotton core is provided in the middle of the main body, the absorbent cotton core is arranged along the width direction of the main body, the absorbent cotton cores are arranged at equal intervals, and an absorbent groove is provided between each absorbent cotton core.

[0006] By adopting the above technical solution, the absorbent cotton cores are arranged at equal intervals and there are absorbent grooves between each absorbent cotton core. Urine can enter the absorbent grooves before being absorbed, so that the urine can be evenly distributed between the absorbent cotton cores, improving absorption efficiency and absorption capacity. At the same time, it avoids discomfort caused by local over-wetting. In addition, the absorbent grooves can temporarily store urine, reducing urine leakage and improving the user experience.

[0007] Optionally, non-woven fabric layers are provided on both sides of the absorbent cotton core, and the absorbent cotton core is disposed between the non-woven fabric layers.

[0008] By adopting the above technical solutions, the non-woven fabric layer effectively prevents liquid from seeping out of the absorbent core, improving the product's leak-proof performance and comfort. At the same time, the non-woven fabric layer also increases the product's softness and breathability, enhancing the user experience.

[0009] Optionally, an adhesive layer is provided on the non-woven fabric layer on the upper side of the absorbent core corresponding to the absorbent groove, and the adhesive layer can be bonded to the non-woven fabric layer on the lower side of the absorbent core.

[0010] By adopting the above technical solution, the non-woven fabric is bonded with an adhesive layer to form a wave shape, which can reduce the situation where the absorbent cotton core expands and covers the absorbent groove, thus reducing the leakage of urine. It can also further reduce the amount of urine squeezed out at the absorbent groove, so that urine cannot enter the absorbent groove in large quantities, thereby reducing the situation of urine back seepage caused by movement and other compression.

[0011] Optionally, a one-way permeable membrane is provided on the nonwoven fabric layer at the position corresponding to the adhesive layer. Liquid can only pass through the one-way permeable membrane from the upper side. The one-way permeable membrane is provided on the upper side of the nonwoven fabric layer.

[0012] By adopting the above technical solution, a one-way permeable membrane is set on the non-woven fabric layer, allowing liquid to pass through the non-woven fabric layer and enter the absorbent groove for absorption by the absorbent cotton core, thereby further preventing urine backflow and improving the user experience.

[0013] Optionally, a water-resistant layer is provided on the non-woven fabric layer below the absorbent cotton core, the water-resistant layer is disposed between the non-woven fabric layer and the absorbent cotton core, and the absorbent cotton core is bonded to the water-resistant layer.

[0014] By adopting the above technical solution, a waterproof layer is set on the non-woven fabric layer under the absorbent cotton core, which can further reduce the leakage of urine from the diaper onto the user's clothes and further improve the user experience.

[0015] Optionally, an antibacterial layer is provided on the upper side of the absorbent cotton core, and the antibacterial layer is disposed between the non-woven fabric layer and the one-way permeable membrane.

[0016] By adopting the above technical solution, an antibacterial layer is set on the upper side of the absorbent cotton core. This antibacterial layer is located between the non-woven fabric layer and the one-way permeable membrane, which can effectively prevent bacterial growth, improve the hygiene performance of the product, and keep the absorbent cotton core dry and clean.

[0017] Optionally, adhesive sections are provided at both ends of the body, and adhesive strips are provided on both sides of each adhesive section. The adhesive strips are used to bond with the adhesive strips of another adhesive section.

[0018] By adopting the above technical solutions, the adhesive sections and strips at both ends of the diaper body ensure the fixation and comfort of the adult diaper, preventing shifting or falling off during use, thereby improving the user experience. At the same time, the adhesive strip design allows for easy adjustment of the diaper's tightness to suit the needs of users with different body types.

[0019] Optionally, a heating patch is also provided on the adhesive section at one end of the main body, the heating patch being used to adhere to the human body.

[0020] By adopting the above technical solutions, the heating patch can be attached to the patient's abdomen to provide warmth, which has a good protective effect on patients suffering from urinary incontinence. It can further reduce the occurrence of urinary incontinence due to discomfort and further improve the user experience.

[0021] In summary, this application has at least the following beneficial effects: This application addresses the problem that existing diapers can absorb urine, but when there is a lot of urine, it tends to accumulate at the absorbent material. Squeezing can easily cause the urine to be squeezed out again, resulting in backflow. If not replaced in time, it can affect the user experience. This application solves the problem by setting up an absorbent groove and bonding the non-woven fabric layer at the absorbent groove to form a wave shape. A one-way permeable membrane is set at the wave to reduce urine backflow and improve the user experience. Attached Figure Description

[0026] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example 1

[0027] A type of adult diaper, such as Figure 1 and Figure 2 As shown, the device includes a main body 1, with an absorbent cotton core 2 located in the middle of the main body 1. The absorbent cotton cores 2 are arranged along the width direction of the main body 1 and are spaced at equal intervals. An absorbent groove 11 is provided between each absorbent cotton core 2. In practice, urine can first flow into the absorbent groove 11 and then be absorbed by the absorbent cotton cores 2 on both sides. The absorbent groove 11 can also temporarily store urine, reducing the possibility of excessive urine that is difficult to absorb and causing backflow.

[0028] like Figure 1 and Figure 2As shown, non-woven fabric layers 3 are provided on both sides of the absorbent cotton core 2, with the absorbent cotton core 2 positioned between the non-woven fabric layers 3. An adhesive layer 31 is provided on the upper side of the non-woven fabric layer 3 corresponding to the absorbent groove 11, and the adhesive layer 31 can bond to the corresponding lower side of the non-woven fabric layer 3 of the absorbent cotton core 2. In specific implementation, the non-woven fabric layer 3 and the absorbent cotton core 2 are connected by hot melt adhesive, and the adhesive layer 31 on the non-woven fabric layer 3 is also hot melt adhesive. After connection, the non-woven fabric layer 3 can form a wavy shape at the point where the absorbent cotton core 2 meets the absorbent groove 11.

[0029] like Figure 1 and Figure 2 As shown, a one-way permeable membrane 4 is provided on the non-woven fabric layer 3 at the position corresponding to the adhesive layer 31. Liquid can only pass through the one-way permeable membrane 4 from the upper side. The one-way permeable membrane 4 is located on the upper side of the non-woven fabric layer 3. In specific implementation, this can reduce the possibility of urine leakage caused by the expansion of the absorbent cotton core 2 covering the absorbent groove 11. It can also further reduce the amount of urine squeezed out at the absorbent groove 11, so that urine cannot enter the absorbent groove 11 in large quantities. Even if urine enters the absorbent groove 11, it cannot seep back through the one-way permeable membrane 4, thereby reducing the possibility of urine backflow caused by movement or other compression.

[0030] like Figure 1 and Figure 2 As shown, a waterproof layer 5 is provided on the non-woven fabric layer 3 below the absorbent cotton core 2. The waterproof layer 5 is located between the non-woven fabric layer 3 and the absorbent cotton core 2, and the absorbent cotton core 2 is bonded to the waterproof layer 5. In specific implementation, the waterproof layer 5 can be made of sodium polyacrylate, which does not come into direct contact with the body and can reduce urine leakage onto underwear.

[0031] like Figure 1 and Figure 2 As shown, an antibacterial layer 6 is also provided on the upper side of the absorbent cotton core 2, and the antibacterial layer 6 is disposed between the non-woven fabric layer 3 and the one-way permeable membrane 4. In specific implementation, the antibacterial layer 6 may include bamboo fiber, which is naturally breathable and has natural antibacterial, anti-mite, and deodorizing effects.

[0032] like Figure 1 and Figure 2 As shown, adhesive sections 12 are provided at both ends of the main body 1, and adhesive strips 121 are provided on both sides of the adhesive sections 12. The adhesive strips 121 are used to bond with the adhesive strips 121 of the other adhesive section 12. In practice, the tightness of the diaper can be adjusted by adjusting the adhesive sections 12 after wearing.

[0033] Working principle: Normal wear is sufficient. When absorbing water, urine permeates unidirectionally into the absorbent groove 11 and is then absorbed by the absorbent cotton core 2. When squeezed, the wavy non-woven fabric layer 3 and the unidirectional permeable membrane 4 work together to protect against backflow of urine. Example 2

[0034] The main difference between Embodiment 2 and Embodiment 1 is that in Embodiment 2, a heating patch 13 is also provided on the adhesive section 12 at one end of the main body 1. The heating patch 13 is fixedly connected to the main body 1 and is used to adhere to the human body. In specific implementation, the heating patch 13 can be a commonly available heat patch. After wearing a diaper, the heating patch 13 can be directly applied to the user's abdomen to keep the abdomen warm.

[0035] Working principle: The basic working principle is the same as in Example 1. Example 2 can attach the heating patch 13 to the user's abdomen after wearing a diaper, so that the user can keep warm and avoid getting cold, reduce the occurrence of urinary incontinence, and further improve the user experience.

[0036] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
