Description

Technical Field

[0001] This utility model belongs to the field of diaper technology, specifically relating to a diaper with easily peelable waist tabs. Background Technology

[0002] Disposable diapers are single-use products made from materials such as non-woven fabric, toilet paper, fluff pulp, superabsorbent polymer (SAP), PE film, and elastic bands. The side tabs (usually referring to Velcro) play a crucial role in diaper design, securing the diaper and ensuring it fits snugly around the baby's waist.

[0003] Improper use of the side tabs on existing diapers, such as sticking the Velcro directly onto the diaper's soft fabric, may cause fabric fibers to get mixed in, affecting the adhesion. Frequent opening and closing of the Velcro tabs may reduce their adhesion, especially when hands are wet or when using care products (such as oil, powder, or bath wash). The Velcro tab's adhesion range and elastic waistband design may not fit all babies. If your baby is overweight or underweight, you may need to find a diaper size that is more suitable for their body type. Utility Model Content

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0023] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a diaper with easily peelable waistbands includes a one-piece molded sheet-like body 1 made of soft, breathable material to keep the baby's skin dry and comfortable. The inner surface of the sheet-like body 1 has two three-dimensional side guards 9, which effectively prevent urine leakage, providing comprehensive protection even for active babies.

[0024] The sheet-like main body 1 includes a crotch area 2 for covering the buttocks. The crotch area 2 is made of highly absorbent material, which can quickly absorb and lock in urine, keeping the inside dry and reducing the occurrence of diaper rash. The design of the crotch area 2 fully considers ergonomics, ensuring good fit and comfort in different body positions.

[0025] The crotch area 2 is connected to the front waist area 3 and the back waist area 4 at both ends, forming the basic frame of the diaper. The outer edges of the front waist area 3 and the back waist area 4 are provided with elastic waistbands 5. The elastic waistbands 5 are made of soft and highly elastic material, which can automatically adjust the tightness according to the baby's waist size, so as not to be too tight and cause marks, nor too loose and cause leakage.

[0026] The elastic waistband 5 in the back waist area 4 has left and right adhesive strips 6 on both sides. Each adhesive strip 6 has at least two layers of Velcro hooks 7 arranged in a stepped pattern. These adhesive strips 6 are not only easy to use, but also feature at least two layers of Velcro hooks 7 arranged in a stepped pattern, allowing parents to choose the most suitable fit according to the baby's waist size, achieving a more personalized adjustment. Furthermore, they are easy to peel off when changing diapers, reducing friction and pulling on the baby's skin.

[0027] The outer surface of the elastic waistband 5 on the front waist area 3 is provided with a textured surface 8 that can match the hook and loop fastener 7. The textured surface 8 is made of soft material with moderate stickiness, which can ensure that the left and right tabs 6 are firmly attached to the front waist area 3 and are not easy to fall off even when the baby is moving around frequently.

[0028] The left and right tabs 6, together with the hook and loop side 7 of the Velcro and the textured side 8 of the front waistband 3, form a disposable absorbent diaper with absorbent properties. When it's time to change the diaper, the textured side 8 can be easily peeled off from the hook and loop side 7 without leaving any residue, thus protecting the baby's delicate skin.

[0029] These diapers with easy-to-remove waistbands not only offer excellent absorbency and comfort, but also greatly simplify the changing process and reduce potential harm to the baby's skin, making them an indispensable and high-quality choice for modern families.

[0030] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the Velcro hooks 7 on the left and right sides 6 are two-layered, with the outer layer having a larger area than the inner layer.

[0031] Specifically, the Velcro hooks on the left and right sides (6) are designed with a two-layer structure, and what's special is that the outer layer is larger than the inner layer, combining practicality and convenience. The larger outer Velcro hook (7) provides a wider range of fastening options, allowing parents to more flexibly adjust the fit when securing the diaper, ensuring the diaper tightly wraps around the baby's waist and effectively preventing urine leakage, which is especially important for babies who are very active or overweight.

[0032] The smaller hook side 7 on the inner layer serves as a spare or auxiliary attachment area. When the outer hook side 7 loses its stickiness due to repeated use, the inner layer can act as an additional fixing point, extending the diaper's lifespan. Furthermore, when it's time to change a diaper but the baby is asleep or it's inconvenient to disturb them, parents can use the inner hook side 7 for temporary fixation, making the changing process easier and minimizing disruption to the baby's sleep.

[0033] Combination Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the Velcro hooks 7 on the left and right sides 6 are multi-layered, and the area of ​​the innermost layer gradually increases from the outermost layer to the innermost layer.

[0034] Specifically, the Velcro hooks on the left and right sides 6 adopt an innovative multi-layer design, with the area gradually increasing from the innermost layer to the outermost layer. This not only improves the fit and stability of the diaper, but also greatly enhances its practicality and flexibility.

[0035] The innermost Velcro hook side 7 is relatively small, but sufficient for basic fastening needs. This layer is designed to be compact, making it easy to quickly secure the diaper in emergencies or when the baby is small. At the same time, the presence of the innermost Velcro hook side 7 also provides additional support and stability to the outer layer. Even if the outer layer's adhesiveness weakens after multiple uses, the innermost layer can still ensure the diaper's basic secure hold.

[0036] As the number of layers increases, the area of ​​the Velcro hook side 7 gradually expands. This gives parents more flexibility when attaching the diaper, allowing them to adjust the attachment position according to the baby's size, activity level, and how well the diaper fits. The larger attachment area not only enhances the diaper's stability but also effectively prevents urine leakage, which is especially important when the baby is active or in a rapid growth phase.

[0037] The multi-layered, gradually increasing hook and loop fastener design also considers the reusability and durability of the diaper. As the outer hook and loop fastener weakens with frequent use, the larger inner hook and loop fastener can serve as a backup adhesive point, extending the diaper's lifespan. This design is both economical and environmentally friendly, reducing unnecessary waste.

[0038] Combination Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the three-dimensional protective enclosure 9 is a single layer set on the sheet-like main body 1.

[0039] Specifically, single-layer 3D diaper cuffs are typically made of soft and elastic materials to ensure a snug fit around the baby's legs without causing any feeling of restriction. This allows the cuffs to naturally expand and contract with the baby's leg movements, effectively preventing urine from leaking through the leg gaps during activity and keeping the inside of the diaper dry and clean.

[0040] The single-layer 3D diaper guard 9 simplifies the diaper manufacturing process, reduces production costs, and makes high-quality diaper products more affordable for more families. At the same time, by reducing the number of layers and seams, the single-layer 3D diaper guard 9 also reduces friction points between the diaper and the baby's skin, lowering the risk of diaper rash and other skin problems.

[0041] Combination Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the three-dimensional protective enclosure 9 is a double-layered structure set on the sheet-like main body 1, with the outer layer having a larger area than the inner layer.

[0042] Specifically, the design of the Double-Layer 3D Leggings 9 features an inner and outer layer structure, with the outer layer having a larger area than the inner layer. This not only enhances the 3D feel and elasticity of the Leggings 9 but also further improves its leak-proof performance. The larger outer layer can more effectively conform to the curves of the baby's legs, forming a tight barrier to effectively prevent urine from seeping through the gaps in the legs during activity or sleep. At the same time, the soft material and good elasticity of the outer layer ensure the baby's comfort and freedom of movement while wearing it, without restricting the baby's normal activities due to tightness.

[0043] The smaller inner layer adheres closely to the sheet-like main body 1, serving to aid in fixation and enhance the three-dimensional effect. The design of the inner layer typically prioritizes the fit with the sheet-like main body 1 and the consistency of materials to ensure the overall comfort and durability of the diaper.

[0044] The double-layer 3D protective barrier design also takes into account the needs of babies of different sizes and ages. For newborns or smaller babies, the smaller area of ​​the inner layer is sufficient to provide a tight fit and leak-proof protection; while as the baby grows and becomes more active, the larger area of ​​the outer layer can better adapt to the baby's leg curves and range of motion, ensuring the stability and comfort of the diaper.

[0045] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the interior of the three-dimensional protective enclosure 9 is provided with elastic bands in the longitudinal direction.

[0046] Specifically, the elastic bands arranged vertically inside the 3D protective barrier 9 undoubtedly add significant value to the diaper's comfort and leak-proof performance. This not only demonstrates meticulous care for the baby's delicate skin but also fully considers the baby's needs at different stages of growth and activity levels.

[0047] The vertical placement of the elastic band inside the 3D leg guards ensures a snug fit around the baby's legs. This fit isn't simply a constraint; the elasticity of the band achieves a secure yet comfortable wrap. As the baby moves, the elastic band naturally stretches and contracts with the baby's leg movements, preventing tightness while effectively preventing urine leakage from the leg gaps.

[0048] In addition to its leak-proof performance, the elastic band inside the 3D protective barrier 9 enhances the diaper wearing experience. When parents put on the diaper, the elastic band naturally conforms to the baby's leg curves, reducing friction and discomfort between the diaper and the baby's skin. At the same time, the elasticity of the band makes putting on and taking off the diaper easier and more convenient, providing parents with a smoother experience.

[0049] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the area between the two three-dimensional protective barriers 9 is the water absorption area. When worn, from the inside to the outside, it includes an inner surface layer 10, a diversion layer 11, an absorption layer 12, and an outer surface layer 13. The inner surface layer 10, the diversion layer 11, the absorption layer 12, and the outer surface layer 13 are all bonded together with hot melt adhesive.

[0050] Specifically, the absorbent zone formed between the two side guards 9 is the core functional area in the diaper design, directly affecting the diaper's absorbency, dryness, and comfort. When worn, from the inside to the outside, this absorbent zone includes the inner surface layer 10, the diversion layer 11, the absorbent layer 12, and the outer surface layer 13. Each layer performs a different function, working together to ensure the diaper's excellent performance.

[0051] The inner layer 10, which comes into direct contact with the baby's skin, is typically made of soft, skin-friendly materials, such as non-woven fabric, to ensure comfort and breathability for the baby. The design of the inner layer 10 also focuses on quickly absorbing urine and guiding it to the drainage layer 11, reducing the contact time between urine and the baby's skin, thereby lowering the risk of skin problems such as diaper rash.

[0052] The flow-guiding layer 11 is located between the inner surface layer 10 and the absorbent layer 12. Its key function is to quickly and evenly disperse urine, preventing excessive accumulation of urine in any area, thereby ensuring that the absorbent layer 12 can fully and efficiently absorb urine. The flow-guiding layer 11 is usually made of a material with flow channels or a three-dimensional structure to increase the diffusion area and speed of urine.

[0053] The absorbent layer 12 is the core of the diaper's absorbent area, typically composed of a mixture of superabsorbent polymer (SAP) and fiber materials, possessing strong absorbency and water-locking properties. When urine is guided to the absorbent layer 12 by the diversion layer 11, the SAP quickly absorbs and locks in the urine, keeping the inside of the diaper dry and clean. Simultaneously, the addition of fiber materials enhances the breathability and softness of the absorbent layer 12, improving wearing comfort.

[0054] The outermost layer 13, as the outermost layer of the diaper, is typically made of waterproof and breathable materials, such as polyethylene film or non-woven composite materials. The main function of the outermost layer 13 is to prevent urine leakage while maintaining breathability and dryness inside the diaper. Through carefully designed ventilation holes and a waterproof layer, the outermost layer 13 allows air circulation while ensuring waterproof performance, reducing stuffiness for the baby.

[0055] The inner surface layer 10, the distribution layer 11, the absorbent layer 12, and the outer surface layer 13 are all bonded together with hot melt adhesive to ensure a tight fit and stable performance between the layers. Hot melt adhesive, as an environmentally friendly and efficient adhesive, can cure quickly in a short time, forming a strong bond. At the same time, the use of hot melt adhesive reduces the irritation and odor that may be caused by traditional glues, improving the overall quality of the diaper.

[0056] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the left and right patches 6 and the elastic waistband 5, as well as the three-dimensional guardrail 9 and the sheet-like main body 1, are all bonded with hot melt adhesive.

[0057] Specifically, the left and right side patches 6 are tightly connected to the elastic waistband 5 using hot melt adhesive, ensuring the patches' stability during the baby's movements and preventing urine leakage due to loosening. The flexibility of the hot melt adhesive also ensures the comfort and fit of the patches 6 when conforming to the baby's waistline, without causing any feeling of restriction. The rapid curing properties of the hot melt adhesive significantly shorten the production cycle and improve production efficiency.

[0058] The adhesion between the 3D protective barrier 9 and the sheet-like main body 1 also relies on hot melt adhesive technology. The 3D protective barrier 9 prevents urine leakage from the legs, and its close fit to the baby's leg curves depends on the stable support of the hot melt adhesive. Through the adhesion of the hot melt adhesive, the 3D protective barrier 9 can be firmly fixed to the sheet-like main body 1, maintaining a stable leak-proof effect even when the baby is active. The environmental friendliness and harmlessness of the hot melt adhesive also ensure that the diaper is gentle on the baby's skin, reducing the risk of allergies and irritation.

[0059] This invention represents a preferred embodiment of the present invention, but its scope of protection is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this invention, based on the technical solution and inventive concept of this invention, shall be covered within the scope of protection of this invention.
