TECHNICAL FIELD
[0001] The utility model relates to the support or fixing device technical field of absorbent article, specifically discloses a fluffy rabbit ear type bubble waistline structure. BACKGROUND
[0002] The bubble waistline structure is formed by setting the area with fluffy cavity in the waistline area of the absorbent article and covering the elastic rubber of the original waistline part, and the main technical effect is to eliminate the large pressure of the small elastic rubber applied to the human skin as much as possible, reduce the stimulation of the skin and improve the air permeability of the waistline area, which is a practical and novel technical scheme for improving the wearing experience of the absorbent article.
[0003] Generally, the bubble waistline structure is formed by wrapping a plurality of groups of elastic rubbers in the interlayer of at least two water-repellent cloths in the form of intermittent composite. This design utilizes the natural shrinkage force of the elastic rubber and the free bending characteristics of the non-composite area, thereby forming a plurality of elastic small cavities around the intermittent composite points. The early bubble waistline still has a large pressure problem at the composite part of the water-repellent cloth.
[0004] In order to solve this situation, a new rabbit ear type bubble waistline is developed, which is composed of an additional structure and is composite in the waist area of the absorbent article. This waistline is named because its waistline structure similar to rabbit ears is attached to the waist area of the absorbent article and has a fluffy cavity.
[0005] However, although there is some improvement, because the elastic rubber is still directly composite with the water-repellent cloth that contacts the skin and then acts on the skin, the effect is not significantly different from the previous technology. At the same time, it does not fully exhibit the unique structural advantages of the fluffy bubble cavity, but makes the overall structure more complex. Therefore, this design still has room for further optimization. SUMMARY
[0006] In view of the technical defects in the background art, the utility model provides a fluffy rabbit ear type bubble waistline structure, which solves the above technical problems and meets the actual needs, and the specific technical scheme is as follows:
[0007] A fluffy rabbit ear type bubble waistline structure, comprising an absorbent main body composed of a bottom layer, an absorbent body and a surface layer composite from outside to inside, the bottom layer is composed of a complete 1 piece of external water-repellent layer and a complete 1 piece of internal water-repellent layer, and a plurality of elastic wires are embedded at both ends of the length direction of the absorbent main body, thereby forming the waistline structure of the absorbent main body;
[0008] The bottom layer is buried with elastic filaments at least 5mm away from the end edges of the length direction of the absorbing body, and the blank non-elastic filament edge region is folded inward after being compounded by the elastic filaments, and a fluffy additional layer is covered on the outside of the waist structure, the fluffy additional layer is folded from one side of the outer water-repellent layer to one side of the inner water-repellent layer, and is compounded on the inner and outer sides of the absorbing body at intermittent compound points with a horizontal interval greater than a vertical interval, and the area of the waist structure is covered by no less than 4 elastic filaments, so that a plurality of elastic cavities are formed between the absorbing body and the fluffy additional layer around each intermittent compound point under the contraction force of the elastic filaments, and the fluffy additional layer does not cover all the elastic filaments.
[0009] As a further technical solution of the utility model, 1 or n intensive transverse compound positions are further included, which divide the elastic cavities into n+1 smaller elastic cavities.
[0010] As a further technical solution of the utility model, the intermittent compound points between the fluffy additional layer and the absorbing body are formed by ultrasonic dot array or hot melt glue dotting.
[0011] As a further optimization of the above technical solution, the intermittent compound points are composed of any one or several of a circle, a polygon, a broken line, a curve and a star.
[0012] As a further technical solution of the utility model, the interval L1 between the elastic filaments in the area covered by the fluffy additional layer of the bottom layer is not equal to the interval L2 between the elastic filaments in the area not covered by the fluffy additional layer, and the interval L2 is greater than the interval L1.
[0013] As a further optimization of the above technical solution, the interval between the elastic filaments is greater than 4mm.
[0014] As a further technical solution of the utility model, the number of the elastic filaments compounded in the bottom layer is 8-48.
[0015] As a further technical solution of the utility model, the fineness of the elastic filaments in the area covered by the fluffy additional layer of the bottom layer is 300-900dtex, and the fineness of the elastic filaments in the area not covered by the fluffy additional layer is 100-500dtex.
[0016] As a further technical solution of the utility model, in the remaining area of the absorbing body not covered by the fluffy additional layer and compounded with elastic filaments, the elastic filaments are connected to the absorbing body through a plurality of intermittent compound points at a transverse equal interval.
[0017] The beneficial effects of this utility model are as follows: The overall structure of the waistband is relatively simple. Relying on the water-repellent and fluffy layer structure attached to the outside of the waistband structure formed by two complete pieces, a new fluffy rabbit ear bubble cavity is formed. The bubble cavity of this structure can exist independently relative to the elastic yarn. Therefore, the binding force of the elastic yarn will not directly act on the additional structure, which improves the fluffiness and breathability of the waistband structure to a certain extent and improves the wearing experience of the waist area when wearing absorbent products.

Detailed Implementation
[0026] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.
[0027] Combination Figures 1 to 5As shown, the utility model discloses a fluffy rabbit ear type bubble waistline structure, including the absorption main body A that is from bottom layer 1, absorbent body 2 and surface layer 3 are sequentially from outside to inside composite, wherein, the outside of absorption main body A refers to the side of the user clothes, and the inside of absorption main body A refers to the side of the user skin, the subsequent "inside and outside" orientation all take this as reference, bottom layer 1 is by the complete 1 piece of external water repellent layer 10 and the complete 1 piece of internal water repellent layer 11 composite and is buried with several elastic filaments 4 at the both ends of the length direction LD of absorption main body A, to form the waistline structure B of absorption main body A with this,
[0028] Bottom layer 1 is buried with elastic filament 4 at the end edge of length direction LD of absorption main body A at least 5mm, and the blank elastic filament edge area C is folded inwards after being delimited with the elastic filament 4 and then being compounded, that is, the length of blank elastic filament edge area C is at least 5mm, and a fluffy additional layer 5 is covered on the outside of waistline structure B, the fluffy additional layer 5 is folded from one side of external water repellent layer 10 to one side of internal water repellent layer 11, and then is compounded on the inside and outside of absorption main body 1 with intermittent composite points 6, and the area of waistline structure B is covered with no less than 4 elastic filaments 4, so that a plurality of elastic cavities 7 are formed around each intermittent composite point 6 between absorption main body 1 and fluffy additional layer 5 under the contraction force of elastic filament 4, and the fluffy additional layer 5 does not cover all elastic filaments 4.
[0029] In the utility model, absorption main body A is a general product concept derived from the basic structure of absorbent products. In other words, any wearable product with bottom layer 1, absorbent body 2 and surface layer 3 compounded in sequence can adopt the fluffy rabbit ear type bubble waistline structure disclosed in the technical solution. Bottom layer 1 is compounded by at least two complete external water repellent layer 10 and internal water repellent layer 11, and elastic filament 4, usually spandex filament, is arranged at the both ends of the length direction LD of absorption main body A to form a waistline base. Since elastic filament 4 is embedded in bottom layer 1 composed of two layers of water repellent cloth, when the elastic filament 4 shrinks, the elastic force directly acts on the inside and outside two layers of water repellent cloth, causing bottom layer 1 to shrink and wrinkle.
[0030] The utility model discloses a waistline structure B, which is characterized by an additional fluffy layer 5 on the basis of the waistline structure B. The additional fluffy layer 5 is discontinuously compounded on the inner and outer sides of the waistline structure B and forms multiple fluffy bubble-like elastic cavities 7 between the waistline structure B and the additional fluffy layer 5. The one side of the elastic cavities 7 is wrapped inside by the additional fluffy layer 5 due to the strong stress, and the additional fluffy layer 5 is not directly constrained by the contraction force of the elastic yarn 4. Therefore, the one side of the elastic cavities 7 is always soft. Specifically, the additional fluffy layer 5 plays the role of a cushion layer relative to the inner side Inside and the outer side Outside of the absorbent main body A, effectively inhibits the high pressure generated by the contraction force of the elastic yarn, and provides the necessary space for ventilation, so that the user's waist skin is better relaxed and is not easy to produce marks.
[0031] Further, in the utility model, the distance between the elastic yarn 4 closest to the end edge and the end edge of the waistline structure B in the flat state should not be too wide to control the blank non-elastic yarn edge area C after folding and not to affect the effect of the additional fluffy layer 5 forming the elastic cavities 7 on the edge, and the elastic yarn 4 closest to the end edge can extend along the edge of the waistline structure B to form a circle of elastic cavities 7 after discontinuous compounding, so that the friction between the user's abdomen and the waist opening of the absorbent article is reduced when the abdomen is wrapped by the waistline structure B, and the touch feeling of the edge hard object is also relatively weakened.
[0032] As shown in Figures 2 to 6 , the longitudinal interval of the discontinuous compounding point 6 is less than the transverse interval, which helps to form a strip-shaped elastic cavity 7 like an organ, and the volume of the larger elastic cavity 7 can significantly improve the air permeability and softness of the waistline structure. Combined with the observation that the elastic cavity 7 is compounded on the outside of the waistline structure B by the additional fluffy layer 5, it looks like a rabbit ear, so it is named rabbit bubble waistline.
[0033] As shown in Figure 7 , as one of the preferred embodiments of the utility model, as a further technical solution of the utility model, it further includes one or n dense transverse compounding positions 8, which divide the elastic cavity 7 into n+1 smaller elastic cavities 7. In this solution, the transverse compounding position 8 and the discontinuous compounding point 6 are arranged in the same interlayer space to divide the elastic cavity 6. After the elastic cavity 7 is divided by the transverse compounding position 7, the shape of the smaller elastic cavity 7 is more stable than that of a complete strip-shaped elastic cavity 7, and the elastic cavity 7 formed in combination with the previous embodiment is more stable and has elasticity, which brings a softer and more comfortable touch to the user's skin.
[0034] In combination Figures 1 to 5 As shown in the drawings, as one of the preferred embodiments of the present application, the discontinuous composite points 6 between the fluffy additional layer 5 and the absorption main body 1 are formed by ultrasonic dot array or hot melt glue dotting. In actual application, the ultrasonic dot array composite technology can provide uniform and firm connection while maintaining the softness and elasticity of the material. While the hot melt glue dotting technology has the advantages of rapid curing and good bonding strength, which ensures the close combination of the fluffy additional layer 5 and the waist structure B. The choice of the two technologies depends on the production cost, efficiency and performance requirements of the final product. In addition, the thickness and density of the fluffy additional layer 5 can also be adjusted according to different use requirements to control the fluffiness and elasticity of the elastic cavity 7, so as to achieve the best comfort and support effect. In the manufacturing process, the distribution density and position of the discontinuous composite points 6 can also be adjusted to optimize the elasticity and support force of the waist structure B, especially the wrapping degree of the elastic cavity 7 to the human skin, so as to meet the wearing needs of users of different body types.
[0035] As a further optimization of the above embodiment, the discontinuous composite points 6 are composed of any one or several of circular, polygonal, polyline, curved, star-shaped; such design not only increases the aesthetics of the waist structure B, but also through different shapes of the discontinuous composite points 6, local elastic adjustment of the fluffy additional layer 5 can be realized, for example, Figure 2 And Figure 3 Among them, a single circle can provide uniform elastic distribution, while a polygon or a polyline can enhance elasticity in a specific direction. Curved and star-shaped can bring a unique appearance design to the waist structure B, while providing additional support points without affecting overall comfort. Further, the above discontinuous composite points 6 can also be used in combination, such as Figure 4 And Figure 5 Among them, the curved and polyline are mixed to obtain different wearing effects in specific areas. Through the diversified design of such discontinuous composite points 6, the individualized needs of different users can be better met.
[0036] In combination Figure 1As shown, as one of the preferred embodiments of the utility model, the spacing L1 between the elastic filaments 4 in the area covered by the fluffy additional layer 5 is not equal to the spacing L2 between the elastic filaments 4 in the area not covered by the fluffy additional layer 5, and the spacing L2 is greater than the spacing L1. In the area not covered by the fluffy additional layer 5, the main action area of the elastic filaments 4 is close to the lower abdomen of the human bladder, while in the area covered by the fluffy additional layer 5, the main action area of the elastic filaments 4 is close to the upper abdomen of the human navel. Therefore, from the perspective of wearing comfort and absorption convenience, the spacing L2 of the elastic filaments 4 at the lower abdomen position is greater than the spacing L1 of the elastic filaments 4 at the upper abdomen position, which helps to wear more comfortably on the human hip. When the spacing of the elastic filaments 4 is reduced, the pressure naturally increases. Therefore, while balancing the pressure, the spacing L1 of the elastic filaments 4 covered by the fluffy additional layer 5 can be appropriately reduced to enhance the elasticity and reduce the pressure through the fluffy additional layer 5.
[0037] As a further optimization of the above embodiment, the spacing between the elastic filaments 4 is > 4 mm. A spacing of 4 mm or more can facilitate the determination of the elastic force size that is comfortable for the human body, and in the case of ensuring that L1 < L2, a spacing of 4 mm or more can also ensure the necessary waist circumference elastic force, avoiding the occurrence of early loosening accidents and leakage when the user wears the absorbent article.
[0038] As one of the preferred embodiments of the utility model, the number of elastic filaments 4 compounded in the bottom layer 1 is 8-48. The number of elastic filaments 4 is adaptively adjusted according to the type and size of the absorbent article. For example, the requirement for elasticity of menstrual pants is lower than that of pull-ups, so the number of elastic filaments 4 required is naturally 8-12. When pull-ups are used by adult users, the number increases with the size, and the maximum does not exceed 48, usually in the range of 24-40.
[0039] As one of the preferred embodiments of the utility model, the fineness of the elastic filaments 4 in the area covered by the fluffy additional layer 5 in the bottom layer 1 is 300-900 dtex, and the fineness of the elastic filaments 4 in the area not covered by the fluffy additional layer 5 is 100-500 dtex. This design allows the elastic filaments 4 in the area covered by the fluffy additional layer 5 to provide sufficient support to maintain the shape and elasticity of the waist circumference, while the thinner elastic filaments 4 in the non-covered area provide a softer touch and moderate elasticity to meet the comfort needs of different body parts. Through this differentiated design, the product not only guarantees the overall elasticity and durability, but also takes into account the wearing comfort.
[0040] As one of the preferred embodiments of the utility model, the elastic filaments are connected to the absorbent body through a plurality of intermittent composite points that are horizontally and equally spaced in the remaining area of the absorbent body that is not covered by the fluffy additional layer. Specifically, if the elastic filaments 4 in the remaining portion are conventionally and closely compounded with the remaining structure of the absorbent body as described above, the absorbent product can indeed maintain sufficient stability and not delaminate, but if the elastic filaments 4 in the remaining portion are compounded with the intermittent composite points 5 as shown in the drawings, the distribution of the intermittent composite points 5 in the latter case is different from that in the former case, that is, the horizontal spacing between the intermittent composite points 5 in the latter case is D2, while the horizontal spacing between the intermittent composite points 5 in the former case is D1, and D1 is greater than D2, which means that the intermittent composite points 5 in the latter case are more densely distributed than those in the former case. In this way, the fluffy and breathable properties of the waist structure of the absorbent body can be improved while ensuring the stability of the waist structure of the absorbent body.
[0041] In actual application, the more densely designed intermittent composite points 5 not only effectively improve the fluffy and breathable properties of the waist structure, but also significantly enhance the durability and anti-deformation ability of the waist structure. Through scientific and reasonable spacing, the bonding force between the elastic filaments 4 and the absorbent body is optimized, which not only prevents the decrease in breathability caused by excessive tightness, but also prevents the problem of loose structure caused by excessive spacing. In addition, this design also facilitates the operation and adjustment during production, especially by reducing the amount of glue, which improves production efficiency. Moreover, through multiple experiments, it has been verified that the fluffy rabbit ear bubble waist structure with this design can still maintain good fluffy state and stable structural performance after long-term use, thereby improving the user experience.
[0042] In summary, although the overall design of the waist structure of the utility model is relatively simple, the technical effect is significantly improved compared to the existing rabbit ear bubble waist structure, that is, by embedding the elastic filaments 4 in the interlayer of the elastic cavity 7, the comfort is significantly improved. The present application forms a fluffy rabbit ear bubble cavity that does not contain elastic filaments 4 by additionally attaching a fluffy layer 5 to the outside of the waist structure B. This structure allows the bubble cavity to exist independently of the elastic filaments, so the contraction force of the elastic filaments does not directly affect the fluffy layer 5 that is in direct contact with the human skin. This not only enhances the fluffy and breathable properties of the waist structure, but also improves the comfort experience of the waist area when wearing the absorbent product.
[0043] The above description is only a preferred embodiment of the utility model, and it should be noted that those skilled in the art can make several improvements and refinements without departing from the principles of the utility model, and these improvements and refinements should also be considered within the scope of protection of the utility model.
