Description

Technical Field

[0001] This utility model relates to the field of sanitary napkin technology, and in particular to antibacterial sanitary napkins. Background Technology

[0002] Sanitary napkins are a very common hygiene product, referring to absorbent products used by women during menstruation. The menstrual environment provides the necessary conditions for microbial growth and reproduction, such as nutrients, suitable temperature, suitable pH level, and gases. Menstrual blood, in particular, is an excellent source of nutrients, allowing microorganisms to thrive and multiply. Based on this, antibacterial sanitary napkins have gradually emerged, aiming to reduce microbial growth and lower the risk of infection.

[0003] Currently, there are three main types of antibacterial agents added to sanitary napkins: inorganic antibacterial agents, organic antibacterial agents, and natural antibacterial agents. The most widely used inorganic antibacterial agent is Ag+ antibacterial technology. Although its antibacterial effect is significant, long-term or excessive use may pose potential health risks. Natural antibacterial agents contain plant-based and animal-based ingredients. Their advantage is safety and environmental friendliness, but their antibacterial rate is lower and their effectiveness is unstable. The biggest advantage of organic antibacterial agents is their high antibacterial rate and stable efficacy. However, organic antibacterial agents are leached, and broad-spectrum antibacterial agents are not selective against beneficial or harmful bacteria, which can disrupt the skin's microecological balance. Since most sanitary napkins currently add antibacterial agents to the surface layer, directly contacting the user's skin, this can negatively impact their health.

[0004] In view of this, the purpose of this utility model is to provide a new technical solution to solve the existing technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides an antibacterial sanitary napkin, which solves the problem that the antibacterial agent directly added to the surface layer will affect the health of users.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An antibacterial sanitary napkin includes a sanitary napkin body, which comprises, from top to bottom, a surface layer, a toilet paper layer, an absorbent core layer, and a breathable bottom film layer, wherein at least one of the toilet paper layer and the absorbent core layer is provided with an organic antibacterial agent, and the outer walls of the sanitary napkin body are provided with side wings integrally connected to the sanitary napkin body on both the left and right sides.

[0008] In the above structure, the organic antibacterial agent is disposed in the absorbent core layer.

[0009] In the above structure, the absorbent core layer has antibacterial additive zones with a length of 50-100mm extending from both ends along the length of the sanitary napkin body, and the organic antibacterial agent is disposed in the antibacterial additive zones.

[0010] In the above structure, a flow guide layer is provided between the surface layer and the toilet paper layer.

[0011] In the above structure, the organic antibacterial agent is disposed within the flow guiding layer.

[0012] In the above structure, the absorbent core layer, the flow guiding layer, and the toilet paper layer are all provided with organic antibacterial agents.

[0013] In the above structure, the back of the sanitary napkin body and the bottom surface of the side wings are both provided with an adhesive layer.

[0014] In the above structure, the surface layer is sterile cotton non-woven fabric, and the breathable bottom membrane layer is made of waterproof and leak-proof material.

[0015] In the above structure, the adhesive backing layer is adhered to the outer surface of the outer packaging and the film paper at the center position, and an easy-tear tab is provided on the outside of the outer packaging.

[0016] The beneficial effects of this utility model are as follows: The organic antibacterial agent in this technical solution is fixedly placed in the structural layer of the sanitary napkin body that does not directly contact the user's skin, which can reduce the growth and invasion of bacteria and reduce the possibility of the organic antibacterial agent affecting the microbial balance of the user's skin; then, by setting a breathable bottom film layer, it is convenient to meet the needs of women for breathability and comfort when using it, and ensure that women's antibacterial and sterilization needs are met when using sanitary napkins, thereby improving the practicality and usability of sanitary napkins.

Detailed Implementation

[0021] The following is in conjunction with the appendix Figure 1-2 The present invention will be further described below.

[0022] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0023] Reference Figures 1 to 2 This invention provides an antibacterial sanitary napkin that achieves precise antibacterial effects by adding organic antibacterial agents at specific points. The sanitary napkin body 105 includes, from top to bottom, a surface layer 1, a toilet paper layer 2, an absorbent core layer 3, and a breathable bottom film layer 5. The surface layer 1 directly contacts the user's skin. At least one of the toilet paper layer 2 and the absorbent core layer 3 contains an antibacterial additive, which is an organic antibacterial agent. Side wings 6, integrally connected to the main body of the sanitary napkin, are provided on both the left and right sides of the outer wall of the sanitary napkin body 105. The various layers are connected and fixed by structural adhesive 11. The surface layer 1 is made of sterile cotton non-woven fabric, and the breathable bottom film layer 5 is made of a waterproof and leak-proof material. The cotton material is skin-friendly, and since the surface layer 1 is in direct contact with the user's skin, using cotton for the surface layer 1 improves user comfort. The bottom of the sanitary napkin body 105 is set with a breathable bottom film layer 5. The breathable bottom film layer 5 is made of a material with multiple micropores inside, which is waterproof and leak-proof. When the user uses it, the private area will not be stuffy and not breathable, reducing the probability of skin problems caused by the sanitary napkin being too stuffy. The waterproof and leak-proof material also makes it more reassuring to use.

[0024] Organic antibacterial agents are selected as the antibacterial additives. Organic antibacterial agents are broad-spectrum, highly effective, and safe, effectively avoiding the potential harm of inorganic antibacterial agents to women's health and the low antibacterial rate and unstable efficacy of natural antibacterial agents. However, broad-spectrum antibacterial agents are not selective against beneficial and harmful bacteria, and direct contact can disrupt the skin's microecological balance. Therefore, the antibacterial ingredients are placed in the surface layer 1, such as the toilet paper layer 2 or the absorbent core layer 3, which do not directly contact the skin. This ensures that the user's skin does not directly contact the organic antibacterial agent, achieving both effective antibacterial effect and safe use.

[0025] Organic antibacterial agents are often selected as antibacterial additives. Commonly used organic antibacterial agents include quaternary ammonium salts, guanidines, halides, and betaines. These organic antibacterial agents have an inhibition rate of up to 99.9% against *Escherichia coli*, *Staphylococcus aureus*, and *Candida albicans*. Among them, quaternary ammonium salt antibacterial agents are broad-spectrum antibacterial agents that exert their antibacterial effect by destroying microbial cells, and their concentration range is usually between 0.01% and 0.1% (mass fraction). Guanidine antibacterial agents are also broad-spectrum antibacterial agents that exert their antibacterial effect by electrostatic adsorption with bacteria, inhibiting the synthesis of cellular metabolic enzymes, and suppressing bacterial reproduction; their concentration range is usually between 0.01% and 3% (mass fraction).

[0026] Reference Figure 1 and Figure 2 In one embodiment, an organic antibacterial agent is disposed in the absorbent core layer 3. Since menstrual blood leaves relatively little residue on the surface layer 1, it mainly accumulates in the absorbent core layer 3. Microorganisms are more likely to grow and multiply in menstrual blood. By adding the antibacterial additive to the absorbent core layer 3 at specific points, the growth of bacteria in the accumulated menstrual blood is inhibited, ensuring the maximum antibacterial function is achieved. At the same time, the antibacterial additive is avoided from being wasted by adding it to non-menstrual blood areas.

[0027] Furthermore, an antibacterial additive zone 31, 50-100mm in length, is provided in the middle of the absorbent core layer 3 along the length of the sanitary napkin body 105, where an organic antibacterial agent is added. The total menstrual bleeding volume for women is typically 30-80ml, and a single ordinary sanitary napkin absorbs approximately 5-10ml of fluid. The absorbed fluid is mainly concentrated in the absorbent core layer 3. This concentrated fluid diffuses from the middle of the absorbent core layer 3 to both sides, with a diffusion length generally 50-100ml. Correspondingly, setting the antibacterial additive zone 31 to extend from the middle to both ends conforms to the diffusion pattern of menstrual blood, effectively inhibiting the growth and reproduction of microorganisms generated in menstrual blood.

[0028] In this embodiment, the production process of the absorbent core layer 3 containing the organic antibacterial agent is as follows:

[0029] Raw material preparation: Select quaternary ammonium salts and solvents with purity meeting pharmaceutical or cosmetic standards (quaternary ammonium salts are used as an example of organic antibacterial agents for illustration).

[0030] Solution preparation: Slowly add the target concentration of antibacterial agent to the solvent and stir until completely dissolved to obtain an organic antibacterial agent solution;

[0031] Impregnation process: The absorbent core layer 3 material is immersed in an organic antibacterial agent solution to ensure complete immersion, and then squeezed and dried to obtain the absorbent core layer 3 material with organic antibacterial agent.

[0032] Furthermore, a flow-guiding layer 4 is provided between the surface layer 1 and the toilet paper layer, and the flow-guiding layer 4 has a seepage-proof structure. When menstrual blood seeps down from the surface layer 1, it flows along the flow-guiding layer 4 to the toilet paper layer 2, and then seeps into the absorbent core layer 3. When the user uses the product, menstrual blood will not seep back out, thus making the product drier and more comfortable to use.

[0033] In one embodiment, an organic antibacterial agent is disposed within the flow-guiding layer 4. By disposing of the antibacterial additive in the flow-guiding layer 4, menstrual blood is subjected to the action of the organic antibacterial agent as it flows through the flow-guiding layer 4, thereby inhibiting the growth and reproduction of microorganisms in the menstrual blood.

[0034] In this embodiment, the flow-guiding layer 4 containing organic antibacterial agent is implemented by adding an organic antibacterial agent solution to the fibers of the flow-guiding layer 4. After the fibers are combed, hot air from a drying device penetrates the fiber web, causing it to be heated and bonded to form an antibacterial nonwoven fabric, thereby obtaining the flow-guiding layer 4 material containing organic antibacterial agent.

[0035] In other embodiments, an organic antibacterial additive is disposed in the tissue paper layer 2.

[0036] Alternatively, organic antibacterial agents may be added to both the toilet paper layer 2 and the diversion layer 4.

[0037] Alternatively, organic antibacterial agents may be added to both the toilet paper layer 2 and the absorbent core layer 3.

[0038] Alternatively, organic antibacterial agents may be added to both the flow-guiding layer 4 and the absorption core layer 3.

[0039] Alternatively, organic antibacterial agents may be added to the flow guide layer 4, toilet paper layer 2, and absorbent core layer 3.

[0040] That is, organic antibacterial agents can be added to any one or any two of the following layers: the distribution layer 4, the toilet paper layer 2, and the absorbent core layer 3, or all three layers can contain organic antibacterial agents.

[0041] Organic antibacterial agents are added to each layer of the structure to comprehensively inhibit the growth and reproduction of microorganisms.

[0042] In this embodiment, the toilet paper layer 2 containing organic antibacterial agent is obtained by uniformly spraying the organic antibacterial agent solution onto the toilet paper layer 2 material and then drying and curing it.

[0043] Furthermore, both the bottom surface of the sanitary napkin body 105 and the side wings 6 are provided with an adhesive layer 7. When using it, the user only needs to stick the adhesive layer 7 to the underwear to secure it, which is more convenient for female users. Moreover, the adhesive layer 7 is adhered to the release paper inside the outer packaging 8, and the outer packaging 8 has an easy-tear tab. When using it, the user only needs to remove the easy-tear tab and then remove the sanitary napkin body 105 from the inside of the outer packaging 8 to use it, thus achieving convenient use.

[0044] In this invention, when using the antibacterial sanitary napkin, the user reduces the growth and invasion of bacteria through the organic antibacterial agent inside the sanitary napkin body 105. Then, by setting a breathable bottom film layer 5, it is easy to meet the needs of women for breathability and comfort when using the sanitary napkin, thus ensuring the antibacterial and sterilization needs of women when using the sanitary napkin, thereby improving the practicality and usability of the sanitary napkin.

[0045] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
