Description

Technical Field

[0001] The utility model relates to the field of sanitary products, and particularly relates to a front and rear fan-tail type off-line formed absorbent structure and a sanitary product thereof. Background Art

[0002] In the prior art, as shown in the Chinese patent application with the publication number CN 101014310 A, the technical solution shown is an absorbent article having a formed absorbent core formed on a substrate, wherein the absorbent core includes a central region and two end regions, and at least one of the end regions is wider than the central region, that is, specifically a core structure with a large width at both ends and a small width in the middle (abbreviated as dumbbell-shaped); it also shows the specific form of forming this structure: "A full-width rectangular absorbent core can be formed on-line on a substrate and then punched or trimmed into a desired shape"; that is, in production, a rectangular structure is first formed, and then the required dumbbell-shaped structure is obtained by cutting. For details, see Figure 1 .

[0003] In this form, the punching or trimming form will generate a considerable amount of waste, resulting in a large material cost. Summary of the Utility Model

[0004] Therefore, the utility model provides a front and rear fan-tail type off-line formed absorbent structure and a sanitary product thereof, which solves the problem of large material cost in the forming of the existing dumbbell-shaped absorbent body.

[0005] To achieve the above object, the utility model is realized by the following technical solutions:

[0006] A front and rear fan-tail type off-line formed absorbent structure includes a body. Define the length direction of the body as the longitudinal direction and the width direction as the transverse direction. The body is an axisymmetric structure along the transverse and / or longitudinal directions. The longitudinal two ends of the body are end regions, and the middle part is the central region. The end regions have end-side transverse edges extending along the transverse direction and end-side straight edges located on both sides of the end-side transverse edges and extending along the longitudinal direction. The transverse two sides of the central region have middle straight edges extending along the longitudinal direction. The middle straight edges are connected to the end-side straight edges through an end-side inclined edge. Define the length of the end-side straight edge as L1, and the length of the middle straight edge as 2L1.

[0007] Preferably, define the transverse width of the central region as L2, and the transverse width L3 of the end region is (1.05 - 2)L2.

[0008] Preferably, the transverse widths of the two end regions are not equal.

[0009] Preferably, the minimum distance between the center of the end-side inclined edge and the middle straight edge is 1 - 100 millimeters.

[0010] A sanitary product adopts the front and rear fan-tail type off-line formed absorbent structure as described above.

[0011] By adopting the foregoing technical solution, the beneficial effects of the present utility model are as follows:

[0012] This technical solution improves the structure of the current absorbent body. Structurally, the width of the end regions at the front and rear ends is large, and the width of the central region is small. The absorbent body is large at the front and rear ends and small in the middle, which can well prevent leakage at the front and rear during use. A nestable split forming form is designed. Compared with the traditional split form, it can greatly reduce the edge waste, thereby greatly reducing the waste of material costs, and the utilization rate of the core material is relatively high.

[0017] The following will specifically describe the embodiments of the present utility model in detail, so as to fully understand how the present utility model uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0018] Refer to Figure 2 and Figure 3 , a front and rear fan-tail type off-line formed absorbent structure, including a body 100. Define the length direction of the body 100 as the longitudinal direction and the width direction as the transverse direction. The body 100 is an axisymmetric structure along the transverse and longitudinal directions. Here, according to design requirements, it can also be only longitudinally or transversely symmetrically designed;

[0019] The longitudinal two ends of the body 100 are end regions 1, and the middle part is a central region 2. The end regions 1 have end-side transverse edges 12 extending in the transverse direction, and end-side straight edges 11 located on both sides of the end-side transverse edges 12 and extending in the longitudinal direction. The two transverse sides of the central region 2 have middle straight edges 21 extending in the longitudinal direction. The middle straight edges 21 and the end-side straight edges 11 are connected by an end-side bevel edge 13. Define the length of the end-side straight edge 11 as L1, and the length of the middle straight edge 21 as 2L1, that is, the length of the middle straight edge 21 is twice the length of the end-side straight edge 11; as Figure 3 shown, when the absorbent material is conveyed, it is conveyed in the longitudinal direction. When designing the cutting line, a small amount of waste is formed at the edge of the absorbent material; adjacent absorbents are staggered with each other in the longitudinal direction, that is, as Figure 3 shown, there are common end-side bevel edges 13 between the absorbent m and the absorbents n1 and n2 respectively. The end-side straight edges 11 on the two end regions 1 on both sides of the absorbent m coincide with 1 / 2 of the middle straight edges 21 of the absorbents n1 and n2; arranged in this way, continuous and staggered segmentation forms a nested production form that only generates waste edges on both sides of the absorbent material; this technical solution improves the current structure of the absorbent. Structurally, the width of the end regions 1 at the front and back is large, and the width of the central region 2 is small. The absorbents at the front and back are large and the middle is small, which can well prevent leakage at the front and back during use; a nestable segmentation and forming form is designed. Compared with the traditional segmentation form, it can greatly reduce the edge waste. Compared with the traditional production form, it can save about 30% of the materials, thereby greatly reducing the waste of material costs and having a high utilization rate of the core material.

[0020] When designing, the minimum distance S between the center of the end-side bevel edge 13 and the middle straight edge 21 is 1-100 mm; structurally, define the transverse width of the central region 2 as L2, and the transverse width L3 of the end region 1 is (1.05-2)L2, that is, the transverse width of the end region 1 is greater than the transverse width of the central region 2, and its ratio has an interval according to different designs to meet the product design and production requirements.

[0021] At the same time, according to the design requirements, the transverse widths of the two end regions 1 can also be made unequal; under normal conditions, the two end-side regions are respectively located at the front and back ends of the sanitary product, and thus the transverse widths of the two end-side regions can be different to meet the design of corresponding products according to different user groups, such as between baby boys and baby girls, or the different main liquid absorption regions of infants and adults, etc.

[0022] In terms of products, as disposable sanitary products, they are mainly diapers, pull-up pants, or menstrual pants or incontinence pants for women during menstruation, etc., and can all adopt the front and rear fan-tail type off-line formed absorbent structure as described above.

[0023] Although the present utility model is specifically shown and described in connection with preferred embodiments, those skilled in the art should understand that various changes may be made to the present utility model in form and detail without departing from the spirit and scope of the present utility model as defined by the appended claims, and all such changes are within the scope of protection of the present utility model.
