Description

Technical Field

[0001] This utility model relates to the field of disposable hygiene products technology, and in particular to a tear-resistant snap-on diaper. Background Technology

[0002] Currently available adult diapers are mainly divided into two categories: pant-style diapers and snap-on diapers. Pant-style diapers are similar to underwear in that they need to be put on and taken off from the legs upwards, making them more suitable for elderly people with some mobility. However, for elderly people who are disabled or have limited mobility, pant-style diapers are more difficult to put on and take off, making them inconvenient for caregivers.

[0003] In contrast, snap-on diapers are more suitable for elderly people with limited mobility because caregivers can place them under the body when the elderly are lying on their side or back and secure them with the snaps. However, in actual use, elderly people with dementia often unconsciously grab and tear the snaps, causing the diaper to come loose or become unusable, thus affecting the stability of the diaper and increasing the burden of care.

[0004] To address this issue, existing technologies have attempted improvements such as increasing the adhesive strength of the fasteners and altering their shape, but these still cannot effectively prevent elderly people with dementia from directly touching and tearing the fasteners. Therefore, there is an urgent need for an improved fastener-type diaper that makes the fastener structure less likely to be touched and torn by elderly people with dementia after wearing, thereby ensuring the stability and reliability of the diaper. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a tear-resistant snap-on diaper.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A tear-resistant snap-on diaper includes a diaper body, a front waist tab, and left and right side tabs. The diaper body includes an outer layer, an absorbent layer disposed inside the outer layer, and an inner liner layer disposed inside the absorbent layer. The front waist tab is fixedly disposed on the front side of the absorbent layer corresponding to the abdomen of the human body, located inside the diaper body. The left and right sides of the front waist tab are respectively provided with slits in the front-to-back direction. The left and right side tabs are respectively fixed to the left and right ends of the back side of the diaper body and can pass through the slits. When wearing the diaper, the left and right side tabs can go around the outer layer of the diaper body, pass through the slits to the inner liner layer, and be fixedly attached to the front waist tab.

[0007] Furthermore, the inner side of the diaper body has elastic shrink bands extending in the front-to-back direction on both sides of the absorbent layer to enhance the fit.

[0008] Furthermore, the diaper includes at least two parallel elastic fibers spaced 5–25 mm apart, the elastic fibers having a resilience of 10–60 cN at 10% elongation.

[0009] Furthermore, the inner side of the diaper body has 1-2 layers of protective barriers on the left and right sides of the absorbent layer, corresponding to the crotch area of ​​the human body. The protective barriers are embedded with elastic ligaments to form a leakage barrier.

[0010] Furthermore, the inner side of the diaper body has reinforcing ribs extending in the front-to-back direction at the position corresponding to the inner side of the human thigh root, which is used to improve the fit of the legs and prevent side leakage.

[0011] Furthermore, the main body of the diaper has an elastic waistband area on the back of the absorbent layer, corresponding to the back of the human body. This elastic waistband area is stretchable in the left and right direction to improve the fit and comfort of the diaper at the waist.

[0012] Furthermore, the left and right end pieces are fixed to the interlayer between the outer layer and the inner lining layer by adhesive or sewing.

[0013] Furthermore, the absorption layer includes an absorption core disposed in the middle and two covering layers covering the absorption core; preferably, the length of the absorption core is 20-40cm and the width is 10-20cm.

[0014] Furthermore, the length of the covering layer at the corresponding crotch area is 40-50cm and the width is 15-25cm; the covering layer forms a circular absorbent part at both ends of the absorbent core, with a width of 20-30cm and a total length of 60-80cm.

[0015] Furthermore, the absorbent core and the cover layer are composed of at least one of cotton core or fluff pulp.

[0016] The aforementioned tear-resistant snap-on diapers feature a front waistband placed inside the absorbent layer with slits, allowing the left and right tabs to be inserted and secured inside. This ensures the tabs remain inside the diaper body after wearing, preventing direct contact and tearing by elderly individuals with dementia and significantly improving the diaper's stability. Attached Figure Description

[0017] Figure 1 This is a structural diagram of the snap-on diaper provided by this utility model. Detailed Implementation

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 As shown, this application provides a tear-resistant snap-on diaper, which includes a diaper body 1, a front waist tab 2, and left and right side tabs 3.

[0020] Specifically, the diaper body 1 includes an outer layer, an absorbent layer disposed inside the outer layer, and an inner lining layer disposed inside the absorbent layer; the front waist tab 2 is fixedly disposed on the front side of the absorbent layer corresponding to the abdomen of the human body, and is located inside the diaper body 1, and the left and right sides of the front waist tab 2 are respectively provided with slits 11 in the front-back direction; the left and right tabs 3 are respectively fixed to the left and right ends of the rear side of the diaper body 1, and can pass through the slits 11; when wearing the diaper, the left and right tabs 3 can go around the outer layer of the diaper body 1, pass through the slits 11 to the inner lining layer, and be attached and fixed to the front waist tab 2.

[0021] This embodiment addresses the problem of traditional snap-on diapers easily coming undone when faced with dementia or unconscious pulling. Through an innovative structural design, the left and right tabs 3 are routed from the outer layer of the diaper body 1, passing through a narrow slit 11 to the inner side and attaching to the front waist tab 2. This ensures that the snap-on part is located inside the diaper's inner lining layer after wearing, effectively concealing the snap-on structure and reducing the likelihood of dementia patients directly contacting the snap-on. Compared to existing technologies that simply rely on enhancing adhesion or changing shape, this design structurally avoids tearing paths, significantly improving the diaper's stability and resistance to interference during wear. This reduces the burden on caregivers who frequently change or re-secure diapers, improving care efficiency and reliability, and is particularly suitable for the daily care needs of disabled and cognitively impaired elderly individuals.

[0022] The inner side of the diaper body 1 has elastic shrink bands 4 extending in the front-to-back direction on the left and right sides of the absorbent layer, which are used to enhance the fit of the diaper during wearing and significantly improve the leak-proof performance and usage stability.

[0023] The elastic shrink band 4 comprises at least two parallel elastic fibers spaced 5–25 mm apart, each fiber exhibiting a resilience of 10–60 cN at 10% elongation. The use of multiple parallel elastic fibers significantly enhances the flexibility of the mechanical response and the fit. Controlled spacing ensures a more even distribution of elasticity, preventing discomfort or skin indentations caused by concentrated localized tension. The optimized resilience range of the fibers maintains a stable fit across different body types and activity levels, effectively preventing urine leakage and diaper shift.

[0024] The inner side of the diaper body 1 has 1-2 layers of protective barriers 5 on both sides of the absorbent layer, corresponding to the crotch area of ​​the user. Each protective barrier 5 has embedded elastic ligaments to form a leakage barrier. By setting 1-2 layers of protective barriers 5 with elastic ligaments, this embodiment adds a reliable leak-proof barrier to the traditional absorbent structure, significantly enhancing the diaper's anti-leakage ability in the crotch area. Compared to ordinary diapers that rely solely on the absorbent core, the protective barrier structure actively intercepts lateral flow, exhibiting superior sealing performance, especially when the user is lying flat or on their side, reducing the probability of leakage and lowering the frequency of changes and care difficulties.

[0025] The inner side of the diaper body 1 has a reinforcing rib 6 extending in the front-to-back direction at the position corresponding to the inner side of the human thigh root, which is used to improve the fit of the legs and prevent side leakage. Through the coordinated design of the rigidity and flexibility of the material, the rib provides directional support during wear, so that the diaper can fit more closely to the curve of the human body at the leg root, effectively filling the gaps in the legs and maintaining structural stability.

[0026] The diaper body 1 has an elastic waistband area 7 on the back of the absorbent layer, corresponding to the back of the human body. The elastic waistband area 7 is stretchable in the left and right direction to improve the fit and comfort of the diaper at the waist and avoid the problems of looseness, slippage or local pressure caused by traditional non-elastic structures.

[0027] The ends of the left and right adhesive strips are fixed to the interlayer between the outer and inner lining layers by adhesive or sewing, significantly improving their tensile and tear resistance and preventing tearing or detachment of the adhesive area due to repeated pulling or uneven stress during use. At the same time, this embedding method avoids exposed edges of the fasteners, reducing the risk of skin friction or irritation and improving wearing safety and comfort.

[0028] The absorbent layer includes an absorbent core 8 located in the center and two covering layers 9 covering the absorbent core 8; preferably, the absorbent core 8 has a length of 20–40 cm and a width of 10–20 cm. By adopting a structurally sound absorbent core 8 size and a two-layer covering layer 9 design, the diaper achieves optimized absorption efficiency, even distribution, and structural stability. The double-sided covering not only enhances the fixation of the absorbent core, preventing displacement or breakage during wear, but also improves the multidirectional diffusion of liquid, reducing backflow problems caused by localized accumulation.

[0029] The cover layer 9 has a length of 40–50 cm and a width of 15–25 cm at the corresponding crotch area. The cover layer 9 forms circular absorbent portions at both ends of the absorbent core 8, with a width of 20–30 cm and a total length of 60–80 cm. This embodiment significantly improves the diaper's liquid control capability and resistance to localized saturation. Compared to traditional strip-shaped absorbent structures, this design is better able to adapt to changes in liquid direction during dynamic states such as sitting, lying down, and turning over, reducing the risk of side leakage and backflow caused by urine accumulation in concentrated areas. Simultaneously, the circular absorbent portions have high structural inclusiveness and cushioning performance, distributing the pressure during high-volume absorption and improving overall safety and continuous protection. It should be understood that the geometry of the cover layer 9 can be designed with various contours such as ellipse, rhombus, or gourd shape to achieve optimized body fit and liquid distribution path control.

[0030] The absorbent core 8 and the cover layer 9 are composed of at least one of cotton core or fluff pulp, ensuring that the diaper achieves excellent levels in absorbency, flow rate, and water retention. The cotton core has high liquid retention and structural stability, making it suitable for long-term wear; the fluff pulp helps to quickly diffuse urine, reducing the risk of localized fluid buildup.

[0031] The above description of embodiments of the present invention, through which those skilled in the art are able to implement or use the present invention, will be readily apparent to those skilled in the art. Various modifications to these embodiments will be readily apparent to those skilled in the art. The general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novelty disclosed herein.
