Description

Technical Field

[0001] This utility model relates to the field of pull-up pants technology, specifically a pull-up pant with adjustable waist and leg circumference. Background Technology

[0002] Current pull-up diaper technology has significant limitations in its waist and leg adjustment methods. Most pull-up diapers currently use a single-piece adjustment design, meaning that waist and leg measurements are adjusted simultaneously, without the ability to fine-tune either one individually. While this design can meet basic wearing needs to some extent, it cannot fully accommodate the differences in body characteristics among users. For example, for individuals with unusual waist-to-leg proportions, the single-piece adjustment may result in a fit at the waist but too tight at the leg openings, or vice versa, affecting comfort and fit.

[0003] Patent publication number: CN1937986A, publication date: March 28, 2007, discloses a patent entitled "Wearable Article," comprising a main body and a connecting mechanism. The main body has a longitudinal axis and a transverse axis intersecting it, an inner surface and an outer surface facing it, first and second waist regions forming a waist opening, and a crotch region extending between the first and second waist regions and forming a pair of leg openings together with these regions. The connecting mechanism is used to connect the two sides of the main body together. The connecting mechanism consists of a flat, rigid connecting piece and a locking part. The rigid connecting piece has a front end and a base end separated from each other along the transverse axis, the front end facing the longitudinal axis, and the base end fixed to each side of the first waist region. The locking parts are located on both sides of the second waist region and can be detachably locked with the connecting piece. The first end of this pull-up panty is fixed to the back waistband 4, therefore it can only be adjusted as a whole, with limited adjustment freedom. Utility Model Content

[0004] This invention provides a pull-up trouser with adjustable waist and leg circumference. By setting side seals and upper leg circumference adjustment parts, the waist and leg circumference can be adjusted separately to adapt to different user body shapes and increase the degree of adjustment freedom.

[0005] A further objective of this invention is to improve user comfort by adjusting the adjustment area of ​​the inwardly folded front panel, so that there are no protruding parts inside after adjustment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable waist and leg circumference pull-up trousers, comprising an integral composite absorbent body and a waist body, the waist body comprising a front piece and a back piece, the front piece having adjustment areas on both sides, the front piece and the back piece being connected by side seals; the outer non-woven fabric of the waist body having a waist adjustment component near the waist and a leg adjustment component near the leg circumference; one end of the adjustment component is fixed to the front and back pieces by side seals, and the other end has a fastener near the front piece, folding inwards to the adjustment area for adjustment.

[0007] Preferably, the waistband body comprises an outer non-woven fabric layer and an inner non-woven fabric layer. The double-layer non-woven fabric structure enhances the stability and comfort of the waistband body, while providing better support for internal elastic bands and other structures, thus improving the overall wearing experience.

[0008] Preferably, an elastic band is provided between the outer and inner non-woven fabric layers. The elastic bands are evenly distributed at the bottom and densely distributed near the top. This distribution design allows the elasticity of the waistband to be adjusted according to human physiological characteristics at different positions. The denser distribution of elastic bands at the top allows for a better fit to the waist curve, providing a more stable fixation and preventing the pull-up pants from slipping down.

[0009] Preferably, the front panel, back panel, and upper leg circumference adjustment piece are connected by a side seal. The fasteners are Velcro. This connection method ensures a more robust overall structure for the pull-up trousers, while facilitating the installation and use of the adjustment piece, thus improving product reliability and lifespan.

[0010] Preferably, the waist and leg circumference adjustment pieces are used to adjust the waist and leg circumference separately. The adjustment area occupies 2 / 3 to 4 / 5 of the front panel. By controlling the waist and leg circumference separately through independent adjustment pieces, users can make precise adjustments according to their own body characteristics, avoiding the discomfort caused by traditional full-piece adjustment, and significantly improving the fit and comfort of the garment.

[0011] Preferably, the composite absorbent core includes a cotton core with several flow-guiding grooves and pressure points. The design of these flow-guiding grooves and pressure points allows for rapid guidance of liquid flow into the absorbent core, improving absorption efficiency, preventing backflow, keeping skin dry, and reducing the occurrence of skin problems.

[0012] Preferably, the composite absorbent core has a crotch elastic band at its center, which is linearly arranged along the length of the composite absorbent core. The crotch elastic band design better conforms to the curve of the human crotch, providing a more snug fit, while enhancing the pull-up pants' three-dimensionality and leak-proof performance.

[0013] Preferably, several flow-guiding grooves form a boat-shaped structure, with three-dimensional elastic bands on both sides of the boat-shaped structure. The flow-guiding grooves and pressure points of the boat-shaped structure, combined with the three-dimensional elastic bands, can effectively prevent liquid leakage while enhancing the three-dimensionality and fit of the pull-up diapers, thus improving the user experience.

[0014] Preferably, non-woven fabric is provided on both sides of several pressure points of the flow channels. The non-woven fabric can further enhance the breathability and comfort of the absorbent, while preventing liquid from seeping out from the pressure points of the flow channels, thus improving the overall performance of the product.

[0015] Preferably, the back panel is larger than the front panel, and the pull-up diaper itself is hourglass-shaped. The hourglass design is more ergonomic, better conforming to the curves of the hips and waist, providing a more stable fit, and enhancing aesthetics.

[0016] The beneficial effects of this utility model are as follows: This utility model provides a pull-up pant with adjustable waist and leg circumference. By setting side seals and upper leg circumference adjustment parts, the waist and leg circumference can be adjusted separately, which can adapt to different users' body shapes and expand the degree of adjustment freedom.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, 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.

[0025] In the fields of infant care and adult incontinence care products, pull-up diapers have gained popularity among consumers due to their ease of wear. However, existing pull-up diaper technology has significant limitations in waist and leg adjustment methods. Most pull-up diapers on the market currently use a one-piece adjustable design, meaning that waist and leg adjustments can only be made simultaneously, without the ability to make individual fine adjustments to either the waist or leg circumference. While this design can meet basic wearing needs and provide basic convenience to users to a certain extent, it is difficult to fully adapt to the significant differences in body characteristics among different users in actual use.

[0026] Human body shapes vary greatly, with different individuals having different waist and leg circumference ratios. For some people with unique waist and leg circumference ratios, one-piece adjustable pull-up diapers can often cause inconvenience. For example, some babies may have a rounder waist and abdomen but relatively slender legs. With one-piece adjustable pull-up diapers, if the waist is adjusted to a suitable position, the leg area may become too tight, leaving red marks, restricting leg movement, and affecting blood circulation. Conversely, if leg comfort is prioritized, the waist may become too loose, causing the pull-up diaper to slip down easily, reducing comfort and potentially causing side leakage, severely impacting its effectiveness. Similarly, for overweight adults with significant differences between their waist and leg circumferences, or for slender individuals with long legs, one-piece adjustable pull-up diapers may struggle to simultaneously meet the needs of both waist and leg circumference, failing to achieve an ideal wearing experience.

[0027] To address the aforementioned issues, this utility model proposes an adjustable waist and leg circumference pull-up trousers. Through innovative design of the product structure, the side seal 1.3 and upper leg circumference adjustment piece 1.5 are cleverly designed, successfully realizing separate adjustment of the waist and leg circumference. This effectively adapts to the body characteristics of different users, greatly expanding the freedom of adjustment and bringing users a more comfortable and fitting wearing experience.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the adjustable waist and leg circumference pull-up pants mainly consist of a one-piece composite absorbent body 2 and a waist body 1. The waist body 1, as the key component for precise adjustment, is ingeniously designed. The waist body 1 comprises a front piece 1.1 and a back piece 1.2, which are tightly connected by a side seal 1.3. This connection not only gives the waist body 1 its complete shape but also provides a stable and reliable structural foundation for the subsequent adjustment function. Two important adjustment components are specially designed on the outer non-woven fabric 1.7 of the waist body 1: a waist adjustment component 1.4 near the waist and a leg adjustment component 1.5 near the leg circumference. Both the waist adjustment piece 1.4 and the leg adjustment piece 1.5 are securely fixed at one end to the side seal 1.3, ensuring they will not easily loosen or fall off during frequent use. The other end has a fastener 1.6 near the front panel 1.1. In actual use, the user simply folds the front panel 1.1 inwards and uses the fastener 1.6 to engage with different positions to easily adjust the waist or leg circumference. It supports compatibility with 2-3 sizes, and the entire operation is simple and easy to understand, requiring no complicated operating skills. Adjustment areas 1.10 are located on both sides of the front panel 1.1. Adjustment is performed by folding the adjustment areas 1.10 inwards. The adjustment areas 1.10 occupy 2 / 3 to 4 / 5 of the front panel 1.1. The design of the adjustment areas 1.10 ensures that there are no protruding parts inside after adjustment, improving user comfort.

[0029] like Figure 6 As shown, the waistband body 1 adopts a double-layer structure design combining an outer non-woven fabric 1.7 and an inner non-woven fabric 1.8. This structure has multiple advantages. From a stability perspective, the two layers of non-woven fabric work together to enhance the overall strength of the waistband body 1, effectively resisting external pulling forces and preventing deformation during daily wear and use. In terms of comfort, the soft and skin-friendly non-woven fabric material closely conforms to the skin, reducing friction and avoiding discomfort caused by prolonged wear. In addition, the double-layer structure provides a good support environment for the internal elastic bands 1.9 and other elastic structures, making the elastic bands 1.9 more stable and durable in their elastic function, further enhancing the overall wearing experience.

[0030] like Figure 6As shown, elastic bands 1.9 are evenly distributed between the outer non-woven fabric 1.7 and the inner non-woven fabric 1.8. These elastic bands 1.9 are not randomly arranged but carefully designed. The lower part of the elastic bands 1.9 is evenly distributed, ensuring that the leg area receives moderate and even elasticity. This ensures a good fit around the legs, effectively preventing urine leakage, without excessively restricting the legs and allowing for normal leg movement. Near the top, the elastic bands 1.9 are distributed more densely, a design that fully considers the physiological characteristics of the human waist. The top of the waist is relatively slender, and the denser distribution of elastic bands 1.9 better conforms to the waist curve, providing a more stable fixation and effectively preventing the pull-up pants from slipping down during use. It also avoids the waist from being unsupported due to overly loose elastic bands 1.9 or leaving marks due to overly tight elastic bands, thus comprehensively improving the wearing comfort of the waist.

[0031] like Figure 1 and Figure 3 As shown, the front panel 1.1, back panel 1.2, waist adjustment piece 1.4, and leg adjustment piece 1.5 are all connected via side seals 1.3, with Velcro fasteners. This connection method has been repeatedly verified and optimized, demonstrating significant advantages. From a structural stability perspective, the side seal 1.3 connection method tightly integrates all components of the pull-up trousers, forming a robust whole. It effectively resists component detachment or cracking when subjected to external pulling forces and daily friction. In the manufacturing process, this connection method facilitates the installation of adjustment pieces, simplifies the production process, improves assembly efficiency, and helps reduce production costs. For users, the robust side seal 1.3 connection method greatly improves product reliability and lifespan, giving users greater peace of mind during use.

[0032] The independent design of the waist adjustment piece 1.4 and the leg adjustment piece 1.5 is the core highlight of this utility model. By separating the waist and leg adjustment functions, each controlled by an independent adjustment piece, users can make precise adjustments according to their unique body characteristics. For users with a larger waist and smaller legs, the waist adjustment piece 1.4 can be appropriately widened to provide a comfortable wrap around the waist, while the leg adjustment piece 1.5 can be tightened to ensure a tight fit around the legs. Conversely, for users with a smaller waist and larger legs, the opposite adjustment method can be used to achieve a personalized fit for both waist and legs. This precise adjustment method completely changes the various drawbacks of traditional one-piece adjustment, significantly improving the fit and comfort of the pull-up diapers. Whether it's active infants or adults who need to be active for extended periods, everyone can enjoy a comfortable and carefree wearing experience with these pull-up diapers, effectively meeting the needs of different users for high-quality care products.

[0033] like Figure 5As shown, the composite absorbent core 2, as the core component of the pull-up diaper for liquid absorption, plays a decisive role in product performance due to its internal structural design. The core contains a cotton core 2.1, which serves as the primary carrier for liquid absorption. Several channeling pressure points 2.2 are formed on its surface using a special process. These pressure points are not randomly distributed but their positions and shapes are determined through precise calculations and repeated experiments. Each channeling pressure point 2.2 forms a recessed channel on the surface of the cotton core 2.1 through a specific pressing process. When liquid comes into contact with the surface of the cotton core 2.1, the channeling pressure points 2.2 utilize their structural characteristics to quickly guide the liquid into the absorbent core. This design breaks through the limitations of traditional absorbent materials that rely solely on natural permeation, accelerating liquid diffusion through physical guidance and significantly improving absorption efficiency. Simultaneously, during the rapid penetration of liquid, the channeling pressure points 2.2 effectively prevent backflow to the skin surface, keeping the skin dry for an extended period. For example, at the moment of concentrated liquid absorption, the flow channel pressure point 2.2 quickly disperses the liquid to the depth of the cotton core 2.1, avoiding local liquid accumulation, thereby reducing skin problems caused by moisture, such as diaper rash, and providing users with a healthier skin care environment.

[0034] like Figure 5 As shown, a crotch elastic band 2.3 is linearly positioned along the length of the composite absorbent body 2 at its center. This elastic band is positioned to closely conform to the curve of the human crotch area, and its elastic material undergoes special treatment, possessing excellent flexibility and resilience. When the pull-up diaper is worn, the crotch elastic band 2.3 naturally adapts to changes in body movement and posture, maintaining a close fit at all times. During actions such as walking and bending, the crotch elastic band 2.3, through its own elastic deformation, neither excessively restricts the crotch area nor provides insufficient support, ensuring the stability of the pull-up diaper in this area. Simultaneously, the presence of the crotch elastic band 2.3 enhances the overall three-dimensional feel of the pull-up diaper, creating an ergonomic three-dimensional space in the crotch area, effectively preventing liquid accumulation and leakage to the outside, further improving leak-proof performance.

[0035] like Figure 5As shown, the several flow-guiding pressure points 2.2 on the cotton core 2.1 are not isolated; they collectively form a boat-shaped structure. This unique shape design offers significant advantages in liquid flow guidance and leak prevention. The two ends of the boat-shaped structure converge towards the center, quickly concentrating and guiding the liquid to the absorption area in the center of the cotton core 2.1, preventing liquid from spreading at the edges. Three-dimensional elastic bands 2.4 are positioned on both sides of the boat-shaped structure. These three-dimensional elastic bands 2.4 are combined with the cotton core 2.1 and surrounding materials through a special sewing process, forming a three-dimensional protective boundary. When liquid spreads to both sides during absorption, the three-dimensional elastic bands 2.4 utilize their elasticity and three-dimensional structure to effectively prevent liquid overflow, further enhancing the leak-proof effect. Simultaneously, in addition to providing leak-proof functionality, the three-dimensional elastic bands 2.4 also enhance the three-dimensional feel of the pull-up diaper in this area, allowing the product to better conform to the curves of the inner thighs and other areas, improving wearing comfort and overall fit.

[0036] On both sides of the pressure point 2.2 of the drainage channel, there is a layer of non-woven fabric 2.5. This non-woven fabric 2.5 undergoes a special process, resulting in excellent breathability and softness. On one hand, its dense fiber structure ensures free airflow, allowing moisture inside the absorbent core to escape promptly, keeping the skin dry and comfortable. On the other hand, the non-woven fabric covering the surface of the pressure point 2.2 effectively prevents liquid from seeping out through the gaps in the pressure point. During the process of liquid being guided by the pressure point 2.2 into the cotton core 2.1, the non-woven fabric plays an auxiliary guiding and protective role, re-absorbing any potentially overflowing liquid and guiding it back to the absorption area, further improving the overall performance of the product. Simultaneously, the soft non-woven fabric material, in direct contact with the skin, reduces friction and discomfort, providing a more delicate wearing experience for the user.

[0037] In terms of overall structural design, the back panel 1.2 is larger than the front panel 1.1, giving the pull-up diaper an hourglass shape. This design fully considers the curves of the human hips and waist. When the user wears the pull-up diaper, the larger back panel 1.2 better wraps around the hips, providing ample coverage and preventing shifting or leakage due to hip movements. Simultaneously, the hourglass waist design naturally conforms to the slender waist area, and with the upper leg circumference adjustment piece 1.5, a stable fixation effect is achieved at the waist, preventing the pull-up diaper from slipping down. This ergonomic design not only enhances the product's practicality but also creates a smooth curve, improving its aesthetics. Whether from a functional perspective of fit and stability or from a visual perspective of aesthetics, the hourglass design makes pull-up diapers more competitive among similar products. In summary, this utility model of adjustable waist and leg circumference pull-up diapers, through the coordinated design of components such as the composite absorbent body 2's internal guide channel pressure point 2.2, crotch elastic 2.3, boat-shaped structure, and non-woven fabric, combined with the overall hourglass structure, achieves separate adjustment of waist and leg circumference, and comprehensively optimizes absorption efficiency, leak-proof performance, and comfort, effectively meeting the needs of different users for high-quality pull-up diapers. By setting the side seal 1.3 and the upper leg circumference adjustment piece 1.5, separate adjustment of waist and leg circumference is achieved, adapting to different user body shapes and expanding the degree of adjustment freedom.

[0038] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
