Description

Technical Field

[0001] The utility model relates to the technical field of female care products, in particular to a segmented absorbing sanitary napkin. Background Art

[0002] Sanitary napkins are a type of sanitary product used by women during menstruation. The main materials are cotton, non-woven fabrics, pulp or polymers and polymer composite paper formed by composites of the above materials. The side design is mainly used to prevent side leakage. From the inside to the outside, it is divided into three layers: surface layer, absorbent core, and bottom layer. When using, first tear off the middle paper tape and stick the adhesive side to the middle of the underwear.

[0003] During the actual use of sanitary napkins, the surface layer is in direct contact with the human genitals and the contact area is large. When menstrual blood flows to the surface layer of the sanitary napkin, some women will discharge blood clots, and the existing sanitary napkins cannot absorb the menstrual blood well, resulting in blood clots easily remaining on the surface layer. During the wearing process, it has a strong "sticky" feeling and is not dry, which reduces the wearing experience. At the same time, it will cause discomfort to the user and produce odor over time.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the utility model clearer, a detailed description is given below in conjunction with the accompanying drawings and specific implementation methods. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is not limited by the specific implementation disclosed below.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to an element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] See also Figure 1-Figure 5 The present embodiment provides a segmented absorption sanitary napkin, comprising a sanitary napkin body 1, with side wings 4 arranged on both sides of the sanitary napkin body 1, a back adhesive 12 arranged on the back of the sanitary napkin body 1, and a release paper 11 attached to the back adhesive 12. The sanitary napkin body 1 comprises a surface layer 5, a gauze layer 6, a guide layer 7, a core layer 1 8, a core layer 2 9 and a bottom layer 10 arranged in sequence from top to bottom.

[0024] The middle part of the sanitary napkin body 1 is provided with a middle absorption zone 3, and the front and rear ends of the sanitary napkin body 1 are provided with end absorption zones 2. The surface layer 5 of the end absorption zone 3 is evenly distributed with a plurality of leakage holes 13, and the leakage holes 13 are in a trumpet-shaped structure with a large top and a small bottom. The guide layer 7 of the end absorption zone 2 is provided with a guide groove 14, and the guide groove 14 is in a structure that is inclined downward from the center to the surroundings. The core layer 18 of the end absorption zone 2 is provided with a receiving cavity 16, and the bottom of the guide groove 14 is provided with a plurality of through holes 15 connected with the receiving cavity 16. The positions of the leakage holes 13, the guide groove 14 and the receiving cavity 16 correspond. Menstrual blood enters the gauze layer 6 through the leakage holes 13, and then flows into the guide groove 14. The inclined setting of the guide groove 14 allows the menstrual blood to flow to the side of the guide groove 14. During the flow process, the menstrual blood enters the receiving cavity 16 through the connecting holes 15 and is retained, and is absorbed by the core layer 18 and the core layer 2 9. The structural arrangement of the end absorption zone 2 enables the sanitary napkin to absorb menstrual blood faster than the prior art, so that the surface of the sanitary napkin can remain dry.

[0025] The middle absorption zone 3 includes a rectangular middle hole 17 provided in the surface layer 5 and a rectangular middle hole 2 18 provided in the guide layer 7. The middle hole 17 and the middle hole 2 18 correspond to each other in upper and lower positions and have the same size. The core layer 8 is provided with accommodating cavities 20 on both sides of the middle hole 2 18, and the side walls on both sides of the middle hole 2 18 are provided with side holes 19 of a long strip structure connected to the accommodating cavities 20. The middle hole 17 in the surface layer forms a groove on the surface of the sanitary napkin, which can better receive and accommodate menstrual blood and blood clots. Menstrual blood and blood clots enter the gauze layer 6 through the middle hole 17, and the gauze layer 6 is as shown in the figure. Figure 5 The grid-like structure shown can divide the blood clots, and the divided small blood clots and menstrual blood enter the middle hole 18, and enter the receiving groove 20 through the side holes 19 on both sides of the middle hole 18 to be retained, and are absorbed by the core layer 1 8 and the core layer 2 9. The structural setting of the middle absorption area 2 increases the speed of the sanitary napkin to absorb menstrual blood compared with the existing technology, and has the function of dividing the blood clots into small blood clots, which is convenient for the absorption of menstrual blood, avoiding the continuous contact between menstrual blood and blood clots and the human body, making the surface of the sanitary napkin relatively dry and improving the comfort of use.

[0026] It should be noted that a support frame 21 of a cross-shaped structure is provided inside the accommodating chamber 16 and the accommodating chamber 20, respectively, and a central support plate 22 of a disc-shaped structure is provided in the middle of the support frame 21. A flow groove 23 is provided on the arm of the support frame 21. The coordination of the support frame, the central support plate 22 and the flow groove 23, on the one hand, maintains the structural stability of the accommodating chamber 1 and the accommodating chamber 2 to avoid collapse under pressure, and on the other hand, the flow groove 23 prevents the setting of the support frame from affecting the accommodating capacity of the accommodating chamber 1 16 and the accommodating chamber 2 20 for menstrual blood.
