TECHNICAL FIELD

[0001] The utility model relates to a disposable sanitary product field, concretely relates to a transverse and longitudinal flow guide absorbing article. BACKGROUND

[0002] The basic structure of the current disposable sanitary product is mostly shown in Chinese patent application CN 114145913 A, a leakage-proof absorbing article, the leakage-proof absorbing article includes a liquid-permeable surface layer, a flow guide layer, an absorbing layer, a breathable bottom layer, and a bottom layer non-woven fabric arranged in order from top to bottom;

[0003] The leakage-proof absorbing article further includes an elastic rubber band three-dimensional containment and a leakage-proof component;

[0004] The liquid-permeable surface layer is provided with the elastic rubber band three-dimensional containment higher than the liquid-permeable surface layer on both sides in the transverse direction;

[0005] Both ends of the liquid-permeable surface layer in the longitudinal direction are provided with the leakage-proof component.

[0006] Among them, the flow guide structure is a flow guide layer structure arranged on the upper surface of the absorbing layer, which conducts liquid to the absorbing layer below through the material properties of the flow guide layer while ensuring a small amount of back seepage.

[0007] The flow guide layer on the market at present is mostly designed to cover the absorbing layer in the whole surface, and such a structure cannot guarantee complete flow guide for instantaneous large-flow body fluid and cannot absorb uniformly and quickly. CONTENT OF THE UTILITY MODEL

[0008] Therefore, the utility model provides a transverse and longitudinal flow guide absorbing article, which solves the problem that the internal flow guide layer of the current absorbing article cannot quickly and uniformly guide flow.

[0009] To achieve the above-mentioned purpose, the utility model is implemented by the following technical scheme:

[0010] A transverse and longitudinal flow guide absorbing article has a longitudinal direction in the length direction and a transverse direction in the width direction, the absorbing article includes a liquid-permeable surface layer, an absorbing core layer, and a liquid-impermeable bottom layer arranged in layers from top to bottom, a flow guide layer is arranged between the liquid-permeable surface layer and the absorbing core layer, the flow guide layer includes two flow guide pieces symmetrically arranged at the center of the absorbing core layer, the two flow guide pieces extend to both ends of the longitudinal direction of the absorbing article, a longitudinal flow guide groove extending in the longitudinal direction is formed between the two flow guide pieces, and a plurality of transverse flow guide parts extending in the transverse direction or inclined to the transverse direction are arranged on the two flow guide pieces.

[0011] Preferably, the transverse flow guide part is a linear hollow groove.

[0012] Preferably, the transverse flow guide part is a plurality of hole parts distributed in a straight line.

[0013] Preferably, each of the transverse flow guiding portions is arranged radially with respect to the center of the absorbent article.

[0014] Preferably, the longitudinal flow guiding groove has a width of any value between 5 and 10 mm.

[0015] Preferably, the transverse edge of the flow guiding layer is within the range of the absorbent core layer.

[0016] By adopting the foregoing technical solution, the present application has the following beneficial effects:

[0017] The present technical solution improves the traditional single-piece flow guiding layer structure, and a longitudinal flow guiding groove is formed in the center of the absorbent article, and transverse flow guiding portions are arranged on both sides of the longitudinal flow guiding groove. For the absorption of body fluid, the longitudinal flow guiding groove directly guides the body fluid to the longitudinal direction of the absorbent article, and the body fluid falling on the flow guiding sheet is guided in the transverse direction by the transverse flow guiding portions, thereby fully utilizing the absorbent core layer. When the amount of body fluid is large, the design of the longitudinal flow guiding groove enables the absorbent core layer at the position to directly contact the body fluid, thereby realizing instantaneous and rapid longitudinal guidance. The design of the flow guiding sheet, in combination with the "boat-shaped" structure formed when the absorbent article is worn, can avoid the direct spreading of the body fluid from the flow guiding layer to the two transverse sides, thereby playing a certain leakage prevention role. Compared with the traditional flow guiding layer, the present application has the effects of rapid guidance and uniform dispersion. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0023] The embodiments of the present application will be described in detail below with reference to specific embodiments, so that the application of technical means to solve technical problems and achieve technical effects can be fully understood and implemented.

[0024] Embodiment One

[0025] Reference Figures 1 to 3 A transverse and longitudinal flow guiding absorbent article, hereinafter taking a diaper as an example, has a longitudinal direction of length and a transverse direction of width, the absorbent article comprises a liquid-permeable surface layer 100, an absorbent core layer 200 and a liquid-impermeable bottom layer 300 arranged in a top-down stack, a flow guiding layer 400 is arranged between the liquid-permeable surface layer 100 and the absorbent core layer 200, the flow guiding layer 400 comprises two flow guiding pieces 401 symmetrically arranged at the center of the absorbent core layer 200, the two flow guiding pieces 401 extend to the longitudinal ends of the absorbent article, and a longitudinal flow guiding groove 402 extending along the longitudinal direction is formed between the two flow guiding pieces 401, wherein the width X of the longitudinal flow guiding groove 402 can be any value between 5-10 mm according to different products; under the traditional structure, the body fluid is infiltrated through the complete flow guiding piece 401; and in the technical solution, a plurality of transverse flow guiding portions 403 extending along the transverse direction can be designed on the two flow guiding pieces 401. The technical solution improves the structure of the traditional single-piece flow guiding layer 400, a longitudinal flow guiding groove 402 penetrating through the longitudinal direction is arranged at the center of the absorbent article, and the transverse flow guiding portions 403 are arranged on both sides of the longitudinal flow guiding groove 402. For the absorption of the body fluid, the longitudinal flow guiding groove 402 directly guides the body fluid to disperse in the longitudinal direction of the absorbent article, and the body fluid falling on the flow guiding piece 401 is guided in the transverse direction by the transverse flow guiding portion 403, thereby fully utilizing the absorbent core layer 200. When the amount of body fluid is large, the design of the longitudinal flow guiding groove 402 enables the absorbent core layer 200 located at the position to directly contact the body fluid, thereby realizing instantaneous and rapid longitudinal guidance.

[0026] Specifically, the transverse flow guiding portion 403 is a linear hollow groove 403a; in this way, the body fluid can directly infiltrate through the hollow groove 403a, thereby further improving the absorption rate in the process of the body fluid spreading to the two sides in the transverse direction; correspondingly, the transverse flow guiding portion 403 can also be a plurality of hole portions 403b distributed in a straight line; regardless of the design of the hollow groove 403a or the array hole portion 403b, only the cutter forming roller needs to be changed during forming, and the selection of the two can be adjusted according to the type of the produced absorbent article (diaper or sanitary napkin, etc.), and the structure form is adjusted accordingly. Herein, only the diaper is taken as an example;

[0027] In terms of structure, the transverse edge of the flow guiding layer 400 is located within the range of the absorbent core layer 200, so as to ensure that the body fluid infiltrated through the flow guiding layer 400 can fall on the absorbent core layer 200 and be accurately absorbed.

[0028] Embodiment Two

[0029] Reference Figure 4Compared with the first embodiment, each of the transverse flow guide portions 403 is arranged obliquely to the transverse direction, forming a radial arrangement with the center of the absorbent article. When worn, the design of the flow guide sheet 401, in combination with the "boat-shaped" structure formed when the absorbent article is worn, can prevent the body fluid from directly spreading to the two sides of the transverse direction from the flow guide layer 400, thereby playing a certain leakage prevention role, and compared with the traditional flow guide layer 400, has the effects of rapid guiding and uniform dispersion.

[0030] The technical solution does not describe the leakage prevention barrier, waist, and other components of the paper diaper product. This is not the main improvement of the technical solution, and will not be described here.

[0031] Although the utility model is specifically shown and introduced in combination with the preferred embodiments, those skilled in the art should understand that various changes can be made to the utility model in form and detail without departing from the spirit and scope of the utility model defined in the appended claims, and all are within the protection scope of the utility model.
