Description

Technical Field

[0001] This utility model belongs to the field of diaper technology, specifically relating to a soft diaper. 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. They come in two types: those for infants and those for adults. The main user groups for disposable diapers are infants and adults. The core technology of disposable diapers is the "core," which has undergone three revolutions in technological development: the first was half a century ago with the invention of disposable diapers; the second was in the 1980s with the application of superabsorbent polymers in diapers, ensuring excellent absorbency. Most mainstream brands use this second-generation core, but these traditional cores still have limitations in absorption speed, backflow prevention, thickness, and core strength. This means that problems such as diaper rash and backflow leakage remain unresolved. Furthermore, most diapers currently on the market still have internal pressure, affecting the baby's comfort. In current disposable diaper products, the outer layer (including the front and sides) that comes into contact with the baby's skin is made of spunbond nonwoven fabric, thermally bonded nonwoven fabric, hot-air nonwoven fabric, or spunbond-meltblown-spunbond and other synthetic fiber nonwoven fabrics. To enhance the urine-trapping performance of the front layer, hydrophilic oils are typically added to these synthetic fiber nonwoven fabrics during the diaper manufacturing process. The sides, however, use synthetic fiber nonwoven fabrics that have undergone a water-repellent treatment. When a baby wears a diaper with a synthetic fiber nonwoven fabric outer layer, this fabric comes into contact with the baby's delicate skin. The chemical fibers in the outer layer and the hydrophilic oils can irritate the baby's delicate skin and may even cause abrasions. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a soft diaper. By using hot melt adhesive, hot pressing, or ultrasonic pressing to bond nonwoven fabric inside the elastic waistband and three-dimensional guardrail to form several elastic channels, the use of hot melt adhesive is reduced, material costs are lowered, the product is softer to the touch, and it is more environmentally friendly, thus solving the problems mentioned above.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a soft diaper, comprising an integrally formed sheet-like main body, the sheet-like main body having an inner surface layer and an outer surface layer, an elastic waistband provided at one end of the sheet-like main body, Velcro fasteners provided on both sides of the elastic waistband, an absorbent layer provided between the inner surface layer and the outer surface layer, and a three-dimensional protective barrier provided around the outer perimeter of the absorbent layer on the outer side of the inner surface layer, the sheet-like main body, the elastic waistband and the three-dimensional protective barrier being bonded by hot melt adhesive or by hot pressing or ultrasonic pressing to form a disposable sanitary absorbent product with water absorption properties.

[0005] Preferably, the interior of the three-dimensional enclosure has a plurality of first elastic bodies arranged along the long side of the sheet-like main body. When the first elastic body is in a stretched state, a first fixing part is provided at both ends. A plurality of first pressing points are symmetrically arranged on both sides of each first elastic body. All the first pressing points are arranged in pairs along both sides of the first elastic body to form an elastic body channel for fixing the first elastic body.

[0006] Preferably, the elastic waistband has a plurality of second elastic bodies arranged along the wide side of the sheet-like main body inside. When the second elastic body is stretched, a second fixing part is provided at both ends. A plurality of second pressing points are symmetrically arranged on both sides of each second elastic body. All the second pressing points are arranged in pairs opposite each other along both sides of the second elastic body to form an elastic body channel for fixing the second elastic body.

[0007] Preferably, the first fixing part, the second fixing part, the first pressing part, and the second pressing part are all formed by hot melt adhesive bonding, hot pressing, or ultrasonic pressing, and the first elastomer and the second elastomer both have wrinkles in their natural state.

[0008] Preferably, the three-dimensional guardrail and elastic waistband are made by wrapping a first elastomer and a second elastomer with a non-woven fabric after folding the fabric in half.

[0009] Preferably, the three-dimensional guardrail and elastic waistband are made by wrapping a first elastomer and a second elastomer between two layers of nonwoven fabric.

[0010] Preferably, the nonwoven fabric materials of the three-dimensional guardrail and the elastic waistband are bonded together by hot melt adhesive bonding, hot pressing, or ultrasonic pressing.

[0011] Preferably, the two sides of the first and second elastomers are formed into elastomer channels by means of hot melt adhesive bonding, hot pressing, or ultrasonic pressing in an intermittent pressing manner.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model proposes a soft diaper where non-woven fabric is bonded together using hot melt adhesive, hot pressing, or ultrasonic pressing within the elastic waistband and three-dimensional support to form several elastomer channels. Compared to ultrasonic pressing of elastomer products, this avoids material shortages caused by the elastomer breaking during production. Furthermore, ultrasonic pressing or hot pressing of non-woven fabric is easier to operate than pressing the elastomer and the top and bottom two layers of non-woven fabric (a total of three layers). This process ensures the diaper's durability, reduces the use of hot melt adhesive, lowers material costs, and results in a softer, more environmentally friendly product.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0017] 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.

[0018] Combination Figure 1 and Figure 2As shown, a soft diaper includes a one-piece molded sheet-like body 1, which has an inner surface layer 2 and an outer surface layer 3. An elastic waistband 4 is located at one end of the sheet-like body 1, and Velcro fasteners 5 are located on both sides of the elastic waistband 4. An absorbent layer 6 is located between the inner surface layer 2 and the outer surface layer 3. A three-dimensional protective barrier 7 is located around the absorbent layer 6 on the outer side of the inner surface layer 2. The sheet-like body 1, elastic waistband 4, and three-dimensional protective barrier 7 are bonded together with hot melt adhesive, or heat-pressed or ultrasonically pressed to form a disposable absorbent diaper with absorbent properties. Specifically, this soft diaper fully considers the baby's comfort and protection, bringing great convenience to modern families. The inner surface layer 2 is made of ultra-soft, non-woven fabric, specially treated to ensure a cloud-like feel when in contact with the baby's delicate skin, effectively reducing friction and irritation and preventing diaper rash. At the same time, this layer material also has a rapid diversion function, quickly guiding urine to the absorbent layer 6 to keep the baby's skin dry. The outer layer 3 allows for free airflow, reducing stuffiness and keeping baby's bottom dry and comfortable for longer. This not only improves comfort but also helps prevent diaper rash. The absorbent layer 6 quickly absorbs and locks in large amounts of urine, keeping the surface dry even after multiple urinations. This effectively extends changing time, reduces nighttime disturbances, and allows baby to sleep soundly through the night. The 3D protective cuffs 7 are a soft, elastic material surrounding the absorbent layer 6, acting as a gentle barrier to effectively prevent urine leakage and ensure cleanliness even when the baby is active. The 3D protective cuffs 7 conform to the baby's leg curves, providing ample protection without feeling restrictive. The elastic waistband 4 is made of highly elastic material, stretching and contracting with the baby's movements without constricting the abdomen, allowing for free movement. The Velcro closures 5 on both sides offer multiple fastening options, allowing parents to adjust the fit according to the baby's waist size to ensure a tight seal and prevent leaks. This diaper is made from environmentally friendly materials that are easily biodegradable after use, reducing environmental impact. Meanwhile, its disposable design makes it easy to change, whether at home or out, providing parents with peace of mind and convenience. With its superior absorbency, breathability, comfort, and leak-proof performance, this soft diaper has become the top choice for modern families, safeguarding the healthy growth of their babies.

[0019] Combination Figure 1 and Figure 2As shown, the three-dimensional protective barrier 7 has several first elastic bodies 71 arranged along the long side of the sheet-like main body 1 inside. First fixing parts 72 are provided at both ends of the first elastic bodies 71 when they are stretched. Several first pressing points 73 are symmetrically arranged on both sides of each first elastic body 71. All the first pressing points 73 are arranged in pairs along both sides of the first elastic body 71 to form an elastic body channel for fixing the first elastic body 71. Specifically, several first elastic bodies 71 are carefully arranged along the long side of the sheet-like main body 1, i.e., the front-to-back direction of the diaper. These first elastic bodies 71 are usually made of highly elastic materials, such as elastic fibers or rubber filaments. They have good elasticity and resilience, and can flexibly adjust with changes in the baby's body shape to ensure that the three-dimensional protective barrier 7 always fits snugly against the baby's leg curves. When the first elastic body 71 is stretched, the first fixing parts 72 are cleverly provided at both ends. These fixing parts 72 not only anchor the position of the first elastic body 71, but also ensure that the first elastic body 71 is evenly stressed when subjected to external tension, avoiding deformation or breakage caused by excessive local stretching. Simultaneously, the first fixing parts 72 facilitate the secure fixing of the first elastic body 71 to the corresponding position on the three-dimensional protective enclosure 7 during production, improving the overall stability of the product. On both sides of each first elastic body 71, several first pressing points 73 are symmetrically arranged. These first pressing points 73 are tightly bonded to the substrate of the three-dimensional protective enclosure 7 through processes such as hot melt adhesive, hot pressing, or ultrasonic pressing, forming stable connection points. All the first pressing points 73 are arranged in pairs along both sides of the first elastic body 71, collectively constructing an elastic body channel for fixing the first elastic body 71. This channel not only provides sufficient support and constraint for the first elastic body 71, but also ensures that it maintains a stable shape and position during stretching and recovery, thereby effectively improving the leak-proof effect and wearing comfort of the three-dimensional protective enclosure 7. Furthermore, the design of this elastomer channel also takes into account the breathability and softness of the diaper. By rationally controlling the number and distribution of the first sealing points 73, the impact on the breathability of the three-dimensional protective barrier 7 can be minimized while ensuring leak-proof performance, allowing the baby's bottom to breathe freely and reducing stuffiness. At the same time, the soft material of the first elastomer 71 and the first sealing points 73 also ensures that the three-dimensional protective barrier 7 provides a gentle and comfortable touch when in contact with the baby's skin, reducing friction and irritation.

[0020] Combination Figure 1 and Figure 2As shown, the elastic waistband 4 has several second elastic bodies 41 arranged along the width of the sheet-like main body 1. Second fixing parts 42 are provided at both ends of the second elastic bodies 41 when they are stretched. Several second pressing points 43 are symmetrically arranged on both sides of each second elastic body 41. All the second pressing points 43 are arranged in pairs along both sides of the second elastic body 41 to form an elastic body channel for fixing the second elastic body 41. Specifically, several second elastic bodies 41 are arranged along the width of the sheet-like main body 1, i.e., the waistband direction of the diaper. These second elastic bodies 41 are also made of highly elastic materials, such as elastic fibers or elastic rubber bands. They have excellent elasticity and resilience, and can closely fit the baby's waist curve, maintaining the stability of the diaper even when the baby is active or rolling over, effectively preventing leakage. When the second elastic body 41 is stretched, second fixing parts 42 are designed at both ends. These second fixing parts 42 not only enhance the connection strength between the second elastomer 41 and the elastic waistband 4 substrate, ensuring the stability of the second elastomer 41 under stress, but also allow the second elastomer 41 to stretch and contract freely within a certain range to adapt to changes in the baby's waist size. The design of the second fixing parts 42 reflects attention to detail, aiming to improve the overall user experience of the diaper. In addition, several second pressing points 43 are symmetrically arranged on both sides of each second elastomer 41. These second pressing points 43 firmly fix the second elastomer 41 to the substrate of the elastic waistband 4 using hot melt adhesive, ultrasonic pressing, or other advanced bonding technologies. All the second pressing points 43 are arranged in pairs along both sides of the second elastomer 41, forming an elastomer channel for fixing and supporting the second elastomer 41. This channel not only provides a stable support structure for the second elastomer 41, but also ensures that it maintains a uniform stress state during stretching and recovery, thereby extending the service life of the second elastomer 41 and improving the durability of the diaper. By properly controlling the number and distribution of the second pressing points 43, the pressure on the waist skin can be minimized while ensuring the stable fixation of the second elastomer 41, and air circulation can be promoted to reduce stuffiness. This not only improves the baby's wearing comfort but also helps prevent skin problems such as diaper rash.

[0021] Combination Figure 1 and Figure 2As shown, the first fixing part 72, the second fixing part 42, the first pressing point 73, and the second pressing point 43 are all formed by hot melt adhesive bonding, hot pressing, or ultrasonic pressing. The first elastomer 71 and the second elastomer 41 both have wrinkles in their natural state. Specifically, the first fixing part 72, the second fixing part 42, the first pressing point 73, and the second pressing point 43 all employ advanced manufacturing processes, such as hot melt adhesive bonding, hot pressing, or ultrasonic pressing, to ensure a strong bond between them and the substrate. These processes not only provide strong adhesion but also achieve precise and efficient fixing without damaging the substrate. In the hot melt adhesive bonding process, by controlling parameters such as temperature, pressure, and time, the hot melt adhesive is evenly applied to the surface of the fixing part or pressing point, then tightly adhered to the substrate, and forms a stable adhesive layer after cooling. Hot pressing technology utilizes high temperature and high pressure to melt and bond the substrates together, forming a strong physical connection. Ultrasonic pressing is a non-contact bonding method that uses heat and pressure generated by high-frequency vibration to locally melt and rapidly solidify the substrate, achieving a fast and clean bonding effect. Both the first elastomer 71 and the second elastomer 41 have pleats in their natural state. The presence of these pleats allows the elastomers to maintain a certain degree of compactness when not stretched, facilitating storage and transportation. Simultaneously, when the diaper is worn by the baby, the pleats gradually unfold as the elastomers stretch, providing greater flexibility for the first and second elastomers 71 and 41, allowing them to better conform to the baby's body shape. This not only improves the comfort of wearing the diaper but also enhances its leak-proof performance. Furthermore, the pleats also provide cushioning, reducing the direct pressure of the first and second elastomers 71 and 41 on the baby's skin, improving softness and comfort. At the same time, the pleat design allows the elastomers to maintain good elasticity and resilience after repeated stretching and recovery, extending the diaper's lifespan. The secure fixing of the first fixing part 72, the second fixing part 42, the first pressing point 73, and the second pressing point 43, along with the pleat design of the first and second elastomers 71 and 41, together constitute an important elastic support and leak-proof structure in the diaper. It not only improves the overall performance and lifespan of diapers, but also brings a more comfortable and healthier wearing experience to babies.

[0022] Combination Figure 1 and Figure 2As shown, the three-dimensional protective barrier 7 and the elastic waistband 4 are made by wrapping a first elastic body 71 and a second elastic body 41 with folded non-woven fabric. Specifically, the manufacturing process of the three-dimensional protective barrier 7 and the elastic waistband 4 reflects careful consideration of material selection and structural design. Both use non-woven fabric as the base material, which is widely used in the field of hygiene products due to its softness, breathability, and good moisture absorption. In the manufacturing process, the non-woven fabric is first folded to form a two-layer structure. This design not only increases the thickness and durability of the three-dimensional protective barrier 7 and the elastic waistband 4, but also provides a stable support base for the subsequent wrapping of the elastic body. For the three-dimensional protective barrier 7, the folded non-woven fabric is cleverly used to wrap the first elastic body 71. The first elastic body 71 is placed near the fold line of the non-woven fabric, and then the two edges of the non-woven fabric are tightly bonded together by hot melt adhesive, hot pressing, or ultrasonic pressing, thereby wrapping the first elastic body 71 inside. This wrapping method not only ensures that the first elastic body 71 can freely stretch and contract along a predetermined path, but also gives the three-dimensional protective wall 7 a soft and elastic feel, allowing it to closely conform to the baby's leg curves and effectively prevent urine leakage. The elastic waistband 4 is also made by wrapping the second elastic body 41 with folded non-woven fabric. In this manufacturing process, the second elastic body 41 is placed within the folded area of ​​the non-woven fabric, and the two edges of the non-woven fabric are tightly bonded together using the same adhesive technology. This allows the elastic waistband 4 to maintain sufficient elasticity while also possessing good stability and durability. When the diaper is worn by the baby, the elastic waistband 4 can closely conform to the baby's waist curve, stretching and contracting freely with the baby's movements, ensuring that the diaper always stays in the correct position and preventing urine leakage from the waist.

[0023] Combination Figure 1 and Figure 2As shown, the three-dimensional protective rail 7 and the elastic waistband 4 are made by wrapping a first elastomer 71 and a second elastomer 41 between two layers of non-woven fabric. Specifically, the three-dimensional protective rail 7 and the elastic waistband 4 adopt a more complex double-layer non-woven fabric structure, with the first elastomer 71 and the second elastomer 41 wrapped between the two layers of non-woven fabric. In the manufacturing process of the three-dimensional protective rail 7, two layers of high-quality non-woven fabric material are first prepared. These two layers of non-woven fabric not only have soft and skin-friendly properties, but also have good breathability and moisture absorption, providing a comfortable environment for the baby's bottom. Subsequently, the first elastomer 71 is placed between the two layers of non-woven fabric to ensure that the three-dimensional protective rail 7 can closely fit the curve of the baby's legs and provide sufficient elastic support when the baby moves. In order to fix the first elastomer 71 between the two layers of non-woven fabric, methods such as hot melt adhesive bonding, hot pressing, or ultrasonic pressing are used to ensure the overall stability and durability of the three-dimensional protective rail 7. Similarly, the manufacturing of the elastic waistband 4 follows a similar principle. Between the two layers of non-woven fabric, a second elastomer 41 is wrapped and secured. This allows the elastic waistband 4 to maintain sufficient elasticity while closely conforming to the baby's waistline, providing stable support for the diaper and preventing urine leakage from the waist. The double-layer non-woven fabric design not only enhances the durability and stability of the 3D support 7 and the elastic waistband 4 but also improves their breathability. The tiny space formed between the two layers of non-woven fabric facilitates air circulation, reduces stuffiness, and keeps the baby's bottom dry and comfortable even when wearing a diaper for extended periods.

[0024] Combination Figure 1 and Figure 2As shown, the nonwoven fabric materials of the three-dimensional protective barrier 7 and the elastic waistband 4 are bonded together by hot melt adhesive bonding, hot pressing, or ultrasonic pressing. Specifically, the three-dimensional protective barrier 7 and the elastic waistband 4 achieve a tight bond between the nonwoven fabric layers through modern advanced processes such as hot melt adhesive bonding, hot pressing, or ultrasonic pressing, thereby ensuring the stability and durability of the overall diaper structure. First, hot melt adhesive bonding, as a common bonding method, plays an important role in diaper manufacturing. By precisely controlling the amount, temperature, and pressure of hot melt adhesive application, manufacturers can achieve strong adhesion between nonwoven fabric layers without damaging the nonwoven fabric material. This bonding method is not only strong and reliable but can also be completed in a short time, improving production efficiency. At the same time, the environmentally friendly characteristics of hot melt adhesive meet the high standards of material safety requirements for modern hygiene products. Second, hot pressing technology is another effective nonwoven fabric bonding method. Under high temperature and high pressure, the surface fibers of the nonwoven fabric material melt and interpenetrate, thereby forming a strong physical bond between the two layers. Hot-pressing technology not only boasts strong bonding strength but also improves the softness and breathability of non-woven fabrics to some extent, enhancing wearing comfort. However, it's crucial to strictly control temperature and time during hot-pressing to avoid excessive damage to the non-woven material. Finally, ultrasonic bonding, as a non-contact bonding method, has seen increasing application in diaper manufacturing in recent years. Through the energy generated by high-frequency vibrations, ultrasonic bonding creates tiny melting points between the non-woven fabric layers. These melting points solidify upon rapid cooling, achieving a tight bond between the non-woven fabric layers. This technology combines speed and efficiency, and it achieves bonding without the addition of any chemical adhesives, making it more environmentally friendly.

[0025] Combination Figure 1 and Figure 2As shown, the sides of the first elastic body 71 and the second elastic body 41 are formed into elastic channels by intermittent pressing through hot melt adhesive bonding, hot pressing, or ultrasonic pressing. Specifically, the way the sides of the first elastic body 71 and the second elastic body 41 of the three-dimensional guardrail 7 and the elastic waistband 4 are fixed, i.e., how they form elastic channels through intermittent pressing, not only affects the elasticity of the diaper but also directly impacts its wearing comfort and leak-proof performance. To ensure that these first elastic bodies 71 and the second elastic bodies 41 can freely expand and contract along a predetermined path while maintaining a firm bond with the non-woven fabric material, the manufacturer uses high-tech methods such as hot melt adhesive bonding, hot pressing, or ultrasonic pressing. These methods each have their advantages, but they all share the common feature of achieving precise fixing without damaging the material properties. During the pressing process, not both sides of the entire elastic body are continuously bonded or pressed, but rather at certain intervals. This spaced-fitting design offers multiple advantages: firstly, it allows the first elastomer 71 and the second elastomer 41 to unfold more smoothly when stretched, providing better elastic support; secondly, the presence of the spacers reduces resistance to the stretching performance of the first and second elastomers 71 and 41, extending their lifespan. Furthermore, the spaced-fitting helps create clear elastomer channels. These channels are arranged along both sides of the first and second elastomers 71 and 41, providing clear guidance for their stretching. When the diaper is worn, these channels ensure that the elastomers function in the correct direction, effectively preventing urine leakage from the edges. The form and spacing of the spaced-fitting are calculated and designed. Manufacturers determine the optimal fitting method and spacing based on the elastomer material, size, and overall structural requirements of the diaper. This ensures both the diaper's elasticity and its comfort and safety during wear.

Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
