Description

Technical Field

[0001] This utility model relates to the field of absorbent core technology, specifically to a foam material core for sanitary napkins. Background Technology

[0002] With the rapid development of the hygiene products market, consumers have increasingly higher demands for hygiene products. Due to the dampness of menstrual blood and the influence of its components, sanitary napkins will begin to breed bacteria after about 20 minutes of use. If not changed in time, bacteria will multiply rapidly, which may cause symptoms such as skin itching, and in severe cases, may even lead to certain gynecological diseases.

[0003] Therefore, existing methods typically involve spraying antibacterial agents on the surface of sanitary napkins to inhibit bacteria. While this method is effective, bodily fluids will remain on the surface of the sanitary napkin for a period of time. Since the surface of the sanitary napkin is flat, the bodily fluids have a large contact area with the skin, and the reaction between the antibacterial agent and the bodily fluids takes time. Therefore, the probability of skin itching and other inflammations is still relatively high. Utility Model Content

[0004] In order to solve at least one of the technical problems mentioned in the background art, the purpose of this utility model is to provide a foam material core for sanitary napkins that accelerates the absorption of body fluids and reduces the contact area between body fluids and human skin.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foamed material core for sanitary napkins, comprising an upper layer, a middle layer, and a lower layer. The upper layer is provided with a liquid storage tank, and an absorbent rod is fixedly installed on the peripheral wall of the liquid storage tank. One side of the absorbent rod extends into the liquid storage tank, and the other side of the absorbent rod extends into the interior of the upper layer. Microcapsules are provided around the absorbent rod. The middle layer is a combination of foamed sponge and absorbent layer, with the foamed sponge located above the absorbent layer. The lower layer is a waterproof layer.

[0006] Furthermore, there are multiple absorber rods, which are evenly distributed along the periphery of the storage tank.

[0007] Furthermore, the upper layer is a combination of hot air guiding non-woven fabric and antibacterial solution soaked cotton, with the antibacterial solution soaked cotton located on the upper side of the hot air guiding non-woven fabric.

[0008] Furthermore, the upper layer is a combination of hot air guiding non-woven fabric and antibacterial solution soaked cotton, with the antibacterial solution soaked cotton located on the upper side of the hot air guiding non-woven fabric.

[0009] Furthermore, the absorbent layer is a polymer layer.

[0010] Furthermore, the absorbent layer is absorbent paper.

[0011] Furthermore, it includes a foam material core for sanitary napkins, with a surface layer on the upper side of the foam material core and a bottom layer on the lower side of the foam material core.

[0012] Furthermore, the bottom layer is a PE film.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When it is necessary to absorb bodily fluids, the sanitary napkin is first placed in the underwear, so that the sanitary napkin is positioned appropriately. When bodily fluids are discharged, they will directly contact the foam material core 3 on the sanitary napkin and be discharged into the storage tank first. The storage tank will temporarily store a large amount of bodily fluids, thereby increasing the absorption efficiency of the foam material core 3 for bodily fluids. At the same time, when the amount of fluid discharged is large, the leakage of bodily fluids is reduced. Moreover, the bodily fluids are stored in the storage tank, reducing the contact area with the skin, thereby reducing the occurrence of skin inflammation such as itching. Attached Figure Description

[0017] The technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Please see Figure 1-2 This embodiment provides a sanitary napkin, including a foamed material core 3 for the sanitary napkin, a surface layer 2 disposed on the upper side of the foamed material core 3, and a bottom layer 1 disposed on the lower side of the foamed material core 3. The bottom layer 1 is a PE film.

[0019] The foamed material core 3 includes an upper layer 4, a middle layer 5, and a lower layer 6. The upper layer 4 is equipped with a liquid storage tank 7, and absorbent rods 8 are fixedly installed on the periphery of the liquid storage tank 7. One side of the absorbent rods 8 extends into the liquid storage tank 7, and the other side extends into the upper layer 4. Microcapsules 9 are arranged around the absorbent rods 8. The middle layer 5 is a combination of foamed sponge 51 and absorbent layer 52. The foamed sponge 51 is mainly used to reduce the reverse osmosis of liquid absorbed into the absorbent layer 52. The foamed sponge 51 is located on the upper side of the absorbent layer 52. The bottom layer 1 is a waterproof layer. The absorbent layer 52 is a polymer layer or absorbent paper.

[0020] When it is necessary to absorb bodily fluids, first place the sanitary napkin inside the underwear, positioning it appropriately. When bodily fluids are discharged, they will directly contact the foam core 3 on the sanitary napkin and be discharged into the storage tank 7 first. The storage tank 7 will temporarily store a large amount of bodily fluids, thereby increasing the absorption efficiency of the foam core 3. At the same time, when the discharge volume is large, it reduces the leakage of bodily fluids. Furthermore, the bodily fluids are stored in the storage tank 7, reducing the contact area with the skin and thus reducing the occurrence of skin inflammation such as itching.

[0021] The body fluid stored in the reservoir 7 partially permeates directly towards the middle layer 5, and some is absorbed by the absorbent stick 8 before being transferred to the middle layer 5, thereby accelerating the absorption of body fluid; this allows some body fluid to be quickly stored in the absorbent stick 8 before flowing to the middle layer 5, improving comfort (that is, quickly reducing the moisture of the sanitary napkin and improving comfort).

[0022] The absorbent rod 8 is surrounded by microcapsules 9, which contain antibacterial powder. When the absorbent rod 8 absorbs body fluid and transfers the liquid to the microcapsule 9, the microcapsule 9 decomposes, thereby releasing the antibacterial powder. The antibacterial powder combines with the body fluid, thereby exerting a certain bactericidal effect and reducing bacterial infection.

[0023] There are multiple absorber rods 8, which are evenly distributed along the side wall of the liquid storage tank 7.

[0024] By setting multiple absorbent rods 8 on the side walls of the liquid storage tank 7, the body fluid in the liquid storage tank 7 can be quickly absorbed, improving human comfort and quickly reducing the wetness of the sanitary napkin on the side that is in contact with the human body.

[0025] To further improve the safety of sanitary napkins and reduce gynecological diseases in women, the upper layer 4 is a combination of hot air guiding non-woven fabric 10 and antibacterial solution soaked cotton 11, with the antibacterial solution soaked cotton 11 located on top of the hot air guiding non-woven fabric 10.

[0026] By placing antibacterial solution soaked cotton 11 on the top layer 4, when the body fluid first comes into contact with the foam material core 3, it will come into contact with the antibacterial solution soaked cotton 11, thus performing an antibacterial and sterilization treatment on the body fluid. At the same time, since the antibacterial solution soaked cotton 11 is on the top layer 4 and comes into contact with the skin, it can relieve skin itching.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
