Description

Technical Field

[0001] This invention belongs to the field of hygiene product packaging bags, and specifically relates to a hygiene product packaging bag with mosquito-repellent function. Background Technology

[0002] Disposable hygiene products are susceptible to insect bites and damage during production, transportation, and storage, leading to product contamination and increased risk of bacterial growth. To ensure the hygiene and integrity of products during storage, transportation, and sales, disposable hygiene products are typically sealed in individual packaging bags. Current disposable hygiene product packaging bags are mostly made of plastic film or composite film materials, primarily focusing on moisture protection, dust prevention, and basic physical isolation, which are insufficient to provide effective protection against external biological factors. In high-temperature, high-humidity environments or environments with active mosquitoes, mosquitoes can easily remain on the surface of the packaging bags and even breed, posing a risk of carrying bacteria and microorganisms and causing secondary contamination, thus affecting the safety of hygiene products and the user experience. While existing technologies may employ insect-repellent packaging to avoid insect infestation, the following problems still exist: 1. Simply spraying insect repellent on the surface or placing insect repellent sachets inside the packaging is not effective. The insect repellent in simple spraying is volatile and has a short protection time, making it difficult to form a long-lasting protection. While placing insect repellent sachets inside the packaging can appropriately increase the protection time, the protection effect on the outside of the packaging and distant areas is poor due to the packaging and location. It is difficult to form a comprehensive insect repellent field, resulting in poor insect repellent effect. Furthermore, the use of the product inside the packaging bag is easily affected by the damage of the sachet. 2. Traditional mosquito repellent packaging uses a single mosquito repellent ingredient, and most of them use chemical repellents (such as DEET, permethrin, etc.). A single mosquito repellent ingredient is not effective against different mosquitoes, and chemical ingredients are not suitable for use with products on intimate areas. They are also volatile and toxic, which is not friendly to infants, young children and pregnant women, and is not convenient for use in the field of hygiene products. Summary of the Invention

[0003] (a) Technical problems to be solved In order to overcome the shortcomings of the existing technology, a hygiene product packaging bag made of plant essential oils or plant extracts is proposed, which has multiple and comprehensive long-lasting mosquito repellent functions, in order to solve one or more of the problems mentioned in the background art.

[0004] (II) Technical Solution This invention is achieved through the following technical solution: This invention proposes a hygiene product packaging bag with mosquito-repellent function, the structure of which includes a bag body; The bag is characterized by having a mosquito-repellent functional layer, which contains mosquito-repellent microparticles. These microparticles are formed by encapsulating and loading mosquito-repellent active ingredients with a slow-release material. The slow-release material includes β-cyclodextrin, chitosan, glycerin, and deionized water. The mosquito-repellent active ingredients include citronellal, eucalyptol, eugenol, menthol, artemisia argyi extract, azadirachtin, and a solubilizer.

[0005] Furthermore, both the inner and outer surfaces of the bag are provided with mosquito-repellent functional layers.

[0006] Furthermore, the mosquito-repellent functional layer is a thin film layer.

[0007] Furthermore, the ratio of the mosquito-repellent active ingredients is as follows: citronellal 30: limonene 20: eugenol 10: menthol 5: artemisia extract 20: azadirachtin 15: solubilizer 100.

[0008] Furthermore, the cosolvent is glycerol or butanediol diluted with water.

[0009] Furthermore, the concentration of the glycerol or butanediol is 50%.

[0010] Furthermore, the ratio of the sustained-release material is 50 β-cyclodextrin: 10 chitosan: 5 glycerol: 20 deionized water, and the ratio of the sustained-release material to the mosquito-repellent active ingredient is 1:15.

[0011] Furthermore, the glycerol in the sustained-release material is 100% glycerol.

[0012] A hygiene product packaging bag with mosquito-repellent function, characterized by comprising the following steps: S1. Dissolve citronellal, citronellol, eugenol, menthol, artemisia argyi extract, and azadirachtin in 50% glycerin or butylene glycol in a certain proportion, mix well, and obtain the active ingredients for mosquito repellency. S2. Dissolve β-cyclodextrin in deionized water at 40–60℃, slowly add the biological mosquito-repellent active ingredient dropwise, and stir to encapsulate it; add chitosan solution and glycerin, homogenize, and obtain slow-release mosquito-repellent microparticles.

[0013] S3. Add to the packaging bag.

[0014] Furthermore, the mixing method in S1 employs ultrasonic mixing.

[0015] Furthermore, the addition method in S3 is coating, impregnation, or compounding.

[0016] (III) Beneficial Effects One of the above technical solutions has the following advantages or beneficial effects: 1. By using plant essential oils or plant extracts: citronellal, citronellol, eugenol, menthol, artemisia argyi extract and azadirachtin, multiple mixed mosquito-repellent active ingredients are formed with a solubilizer. Then, through the synergistic work of β-cyclodextrin, chitosan and glycerin, a complex encapsulation or loading system is constructed to encapsulate or load the mosquito-repellent active ingredients, forming microparticles. This can effectively reduce their volatilization rate, allowing the mosquito-repellent active ingredients to be continuously released for a longer period of time, avoiding the problem of short protection time, and significantly improving the durability and stability of the mosquito-repellent effect. 2. This invention incorporates the mosquito-repellent function into the packaging bag rather than the hygiene product itself. By adding this feature to the bag, a comprehensive and long-lasting mosquito-repellent environment can be formed throughout the bag during storage and transportation. This effectively reduces the risk of mosquito contact and contamination, avoiding problems such as inadequate protection and disruption to the normal use of the product.

[0017] 3. Enhanced Protective Effect with Complex Ingredients: Citronellol acts on olfactory receptor proteins (ORs) on mosquito antennae, causing olfactory interference; combined with eucalyptol, it further reduces the excitability of mosquito olfactory nerves, interfering with mosquitoes' host-locating behavior; eugenol inhibits the mosquito's central nervous system, affecting nerve impulse transmission; menthol activates the mosquito's TRP-like ion channels, causing abnormal cold stimulation and sensory disturbances; Artemisia argyi extract interferes with mosquitoes' sense of smell and inhibits feeding; and azadirachtin interferes with ecdysone, inhibiting larval development and interfering with reproduction. This multi-faceted approach protects mosquitoes from olfaction, nervous system, sensation, feeding, and reproductive interference, ensuring effective protection. All ingredients are plant essential oils or extracts, free from volatile toxicities or other harmful components, making the product suitable for use in intimate areas, for infants, and for pregnant women. Attached Figure Description

[0018] Other features, objects, and advantages of the present invention will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings: Figure 1 This is a schematic diagram of the structural layers of the present invention; In the diagram: bag body-1, mosquito repellent layer-2, mosquito repellent microparticles-3. Detailed Implementation

[0019] Example 1: The present invention will be further described in detail below with reference to embodiments, but the implementation of the present invention is not limited thereto.

[0020] like Figure 1 As shown, the present invention provides a hygiene product packaging bag with mosquito-repellent function: its structure includes a bag body 1; The bag body 1 is characterized by having a mosquito-repellent functional layer 2, and mosquito-repellent microparticles 3 are provided in the mosquito-repellent functional layer 2. The mosquito-repellent microparticles 3 are formed by encapsulating and loading mosquito-repellent active ingredients with a slow-release material. The slow-release material includes β-cyclodextrin, chitosan, glycerin and deionized water. The mosquito-repellent active ingredients include citronellol, eucalyptol, eugenol, menthol, artemisia argyi extract, azadirachtin and solubilizer.

[0021] In one embodiment, the inner and outer surfaces of the bag 1 are provided with a mosquito-proof functional layer 2.

[0022] In one embodiment, the mosquito-repellent functional layer 2 is a thin film layer.

[0023] In one embodiment, the ratio of the mosquito-repellent active ingredient is: citronellal 30: citronellol 20: eugenol 10: menthol 5: artemisia extract 20: azadirachtin 15: solubilizer 100.

[0024] In one embodiment, the cosolvent is glycerol or butanediol diluted with water.

[0025] In one embodiment, the concentration of the glycerol or butylene glycol is 50%.

[0026] In one embodiment, the ratio of the sustained-release material is 50 β-cyclodextrin: 10 chitosan: 5 glycerol: 20 deionized water, and the ratio of the sustained-release material to the mosquito-repellent active ingredient is 1:15.

[0027] In one embodiment, the glycerol in the sustained-release material is 100% glycerol.

[0028] When used, the active ingredients in this mosquito repellent product, through the addition of citronellal, act on olfactory receptor proteins (ORs) on the antennae of mosquitoes, causing olfactory interference. Combined with citronellol, it further reduces the excitability of the olfactory nerves in mosquitoes, interfering with their host-locating behavior. Eugenol then has an inhibitory effect on the central nervous system of mosquitoes, affecting nerve impulse transmission. Menthol activates the TRP-like ion channels of mosquitoes, causing abnormal cold stimulation and sensory disturbances. Artemisia argyi extract interferes with mosquitoes' sense of smell and inhibits feeding. Finally, azadirachtin interferes with ecdysone, inhibiting larval development and interfering with reproduction. This allows the product to protect mosquitoes from multiple aspects, including olfaction, nervous system, sensation, feeding, and reproductive interference, ensuring effective protection. Furthermore, all ingredients are plant essential oils or plant extracts, without any volatile toxicity or other ingredients that may cause discomfort to humans, making the product packaging suitable for use in intimate areas, for infants, and for pregnant women. The active ingredients for mosquito repellent are encapsulated or loaded with a slow-release material composed of β-cyclodextrin, chitosan, glycerol, and deionized water. β-cyclodextrin is used for molecular encapsulation. β-cyclodextrin has a unique truncated pyramidal ring structure, which is hydrophilic on the outside and has a hydrophobic cavity inside. This hydrophobic cavity can "load" individual small molecules to form stable host-guest inclusion complexes. This hydrophobic cavity can act like a "microcapsule" to "load" appropriately sized hydrophobic molecules (or the hydrophobic part of the molecule) into it, forming stable host-guest inclusion complexes through van der Waals forces and hydrophobic interactions, which can improve the stability and water solubility of the ingredients. Chitosan, on the other hand, can be loaded at the micron / nanoscale. Chitosan is a natural cationic polysaccharide with good film-forming properties, biocompatibility, and adsorption properties. Unlike cyclodextrin, chitosan cannot form molecular cavities on its own, but it can be loaded through film formation: after drying, the chitosan solution forms a dense film that can act as a protective coating, encapsulating the components within. The addition of glycerol makes the chitosan film more flexible and helps stabilize the entire system. In use, the mixed solution can be applied to the packaging bag as a film through coating, impregnation, or compounding. After drying, a composite functional film with embedded β-cyclodextrin-essential oil inclusion complex and plasticized chitosan as the matrix is ​​obtained. The mosquito-repellent active ingredient is protected by β-cyclodextrin and further fixed and controlled for release by the chitosan-glycerol network, effectively reducing its evaporation rate and allowing for sustained release of the mosquito-repellent active ingredient over a longer period, avoiding short-term protection and significantly improving the durability and stability of the mosquito-repellent effect.

[0029] Among the active ingredients, the inclusion of glycerin or butylene glycol can better dissolve components that are not easily soluble.

[0030] Example 2: A hygiene product packaging bag with mosquito-repellent function, characterized by comprising the following steps: S1. Dissolve citronellal, citronellol, eugenol, menthol, artemisia argyi extract, and azadirachtin in 50% glycerin or butylene glycol in a certain proportion, mix well, and obtain the active ingredients for mosquito repellency. S2. Dissolve β-cyclodextrin in deionized water at 40–60℃, slowly add the biological mosquito-repellent active ingredient dropwise, and stir to encapsulate it; add chitosan solution and glycerin, homogenize, and obtain slow-release mosquito-repellent microparticles.

[0031] S3. Add to the packaging bag.

[0032] In one embodiment, the mixing method in S1 is ultrasonic mixing. Ultrasonic mixing can better homogenize the particles, making the protective layer on the packaging bag more uniform.

[0033] In one embodiment, the addition in S3 is done by coating, impregnation, or compounding.
