Description

Technical Field

[0001] This utility model relates to a novel sanitary napkin. Background Technology

[0002] Sanitary napkins are a type of menstrual product for women, primarily used to absorb menstrual blood and keep the private area clean and comfortable.

[0003] Structure and Composition Top layer: In direct contact with the skin, it is usually made of soft, breathable materials, such as cotton or dry mesh, to reduce friction and discomfort.

[0004] The diversion layer: allows menstrual blood to permeate evenly and be transferred downwards.

[0005] Absorbent layer: The core part, responsible for quickly absorbing and locking in menstrual blood. Commonly used materials are superabsorbent polymer and fluff pulp.

[0006] Leak-proof layer: The bottom layer is usually made of waterproof material to prevent menstrual blood from seeping into clothing.

[0007] In existing sanitary napkin technology, menstrual blood needs to pass through the surface layer and then penetrate downwards through the diversion layer to the absorbent layer.

[0008] During exercise, menstrual blood flows out slightly faster than normal. Since the permeation of the drainage layer takes time, existing sanitary napkins cannot lock in menstrual blood immediately upon discharge, leading to leakage during exercise.

[0009] Based on the above problems, we designed a new type of sanitary napkin that can quickly lock in menstrual blood and reduce leakage. Utility Model Content

[0010] The technical problem to be solved by this invention is to provide a new type of sanitary napkin that can quickly lock in menstrual blood and reduce leakage.

[0011] To solve the above problems, the present invention adopts the following technical solution: A novel sanitary napkin includes a bottom layer and a top layer. An absorbent layer is wrapped between the bottom layer and the top layer. A diversion layer is disposed between the absorbent layer and the top layer. A raised strip is embossed at the center of the top layer. An inner cavity is formed between the bottom of the raised strip and the diversion layer. The inner cavity is filled with polymer absorbent particles. The diversion layer has multiple concentrated permeation pores at positions corresponding to the polymer absorbent particles. The pore size of the concentrated permeation pores is smaller than the particle size of the polymer absorbent particles.

[0012] Preferably, an arc-shaped first guide strip is embossed on the surface of the surface layer, with both ends of the first guide strip curved outwards. A first interception hole is provided on the surface of the surface layer, located on the inner side of the first guide strip, and the first interception hole penetrates the first guide strip.

[0013] Preferably, two second guide strips are embossed on the surface of the surface layer. The second guide strips are U-shaped and open outward. A second interception hole is provided on the surface of the surface layer. The second interception hole is distributed on the outside of the second guide strip and penetrates the surface layer.

[0014] Preferably, the first interception hole is a tapered hole with its diameter gradually increasing downwards.

[0015] Preferably, the second interception hole is also a tapered hole, with its diameter gradually increasing downwards.

[0016] Preferably, a strip-shaped groove is embossed in the middle of the raised portion.

[0017] Preferably, the absorbent layer has a double-layer structure, with the upper layer being a fluff pulp layer and the lower layer being a non-woven fabric layer.

[0018] The beneficial effects of this utility model are: The difference between this product and traditional sanitary napkins is that it creatively uses super absorbent polymer particles above the diversion layer. These super absorbent polymer particles are designed for the vaginal opening, so that menstrual blood flowing out of the vagina can be quickly absorbed by these super absorbent polymer particles, avoiding leakage during strenuous exercise.

[0019] The surface layer, except for the raised strips, can normally absorb and permeate menstrual blood, and absorb menstrual blood from other areas during exercise, further ensuring the absorption rate and preventing leakage, making it suitable for widespread use. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, in the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "socket," "connect," "through," and "plug-in" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] See Figures 1 to 4 The novel sanitary napkin shown includes a bottom layer 1 and a top layer 2. An absorbent layer 3 is wrapped between the bottom layer 1 and the top layer 2. A flow-guiding layer 4 is disposed between the absorbent layer 3 and the top layer 2. A raised strip portion 201 is embossed at the middle position of the top layer 2. An inner cavity is formed between the bottom of the raised strip portion 201 and the flow-guiding layer 4. The inner cavity is filled with polymer absorbent particles 5. The flow-guiding layer 4 has multiple concentrated permeation holes at the positions corresponding to the polymer absorbent particles 5. The pore size of the concentrated permeation holes is smaller than the particle size of the polymer absorbent particles 5.

[0028] The bottom layer 1 is a leak-proof layer made of waterproof material. In this embodiment, the bottom layer is a polyethylene film.

[0029] The second outer layer is a skin-friendly layer, made of non-woven fabric.

[0030] In the above technical solution, the design of the protruding part 201 can better fit the vaginal opening and quickly allow the menstrual blood flowing out of the vaginal opening to seep downwards. The seeping menstrual blood first comes into contact with the polymer absorbent particles 5 and is absorbed by the polymer absorbent particles 5. The remaining menstrual blood diffuses downwards through the guide layer 4 and is absorbed by the absorption layer 3.

[0031] The absorption method described above can quickly lock in menstrual blood as it flows out, without waiting for the blood to penetrate the drainage layer, thus achieving rapid blood locking. This is especially beneficial during strenuous exercise, as it can reduce leakage.

[0032] With the design of concentrated permeation pores, after the polymer absorbent particles 5 are saturated, menstrual blood can quickly permeate the flow-guiding layer through the concentrated permeation pores, which facilitates absorption by the absorption layer 3 below.

[0033] See Figure 1 As shown, an arc-shaped first guide strip 6 is embossed on the surface of the surface layer 2. The two ends of the first guide strip 6 are curved outward. On the surface of the surface layer 2, a first interception hole 7 is provided on the inner side of the first guide strip 6. The first interception hole 7 penetrates the first guide strip 6.

[0034] During the use of this sanitary napkin, especially when the underwear does not fit properly, resulting in a gap between the sanitary napkin and the vulva, menstrual blood flows out from the vaginal opening and flows down the skin onto the surface of the surface layer 2. The first guide strip 6 can block the menstrual blood that has not yet been able to penetrate, and the first interception hole 7 can quickly transmit this part of the menstrual blood to the guide layer 4.

[0035] See Figure 1 As shown, two second guide strips 8 are embossed on the surface of the surface layer 2. The second guide strips 8 are U-shaped and open outward. A second interception hole 9 is provided on the surface of the surface layer 2. The second interception hole 9 is distributed on the outside of the second guide strips 8 and penetrates the surface layer 2.

[0036] In the above technical solution, the second guide strip 8 can form a barrier at the front and back of the vaginal opening to prevent menstrual blood from leaking out.

[0037] The first interception hole 7 is a tapered hole, and its diameter gradually increases downwards.

[0038] The second interception hole 9 is also a tapered hole, with its diameter gradually increasing downwards.

[0039] See Figure 1 and Figure 3 As shown, a strip-shaped groove 2221 is embossed in the middle of the raised strip portion 201.

[0040] In motion, the groove 2221 can catch the menstrual blood and transfer it to the polymer absorbent particles.

[0041] In this embodiment, the absorbent layer 3 has a double-layer structure, with the upper layer being a fluff pulp layer and the lower layer being a non-woven fabric layer.
