Description

Technical Field

[0001] This utility model relates to the field of microbial agent storage technology, and in particular to a microbial agent protective storage bottle resistant to low-temperature shock. Background Technology

[0002] Microbial agents are important active preparations in agriculture, medicine and environmental protection, and their long-term storage stability directly affects their practical application effects.

[0003] When storing microbial agents, traditional glass or plastic storage bottles experience repeated crystallization of internal moisture during temperature fluctuations, forming sharp ice crystals that pierce microbial cell membranes or damage spore structures, leading to a significant decrease in agent activity. Ordinary storage bottles lack antioxidant design, and residual oxygen inside the bottle or oxygen seeping in from the outside accelerates the metabolic decay of the agent. Existing bottle sealing structures are easily deformed by external forces, causing vacuum failure. Therefore, we propose a low-temperature impact-resistant microbial agent protective storage bottle. Utility Model Content

[0022] This invention features a double-layered bottle design, with an impact-resistant outer layer and a low-temperature-resistant inner layer.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figure 1The illustrated microbial agent protective storage bottle with low-temperature shock resistance includes a bottle body, a functional structure, an adsorption structure, and a protective mechanism. The bottle body is double-layered, with the functional structure located on the inner wall of the bottle body, the adsorption structure located inside the bottle body, and the protective mechanism located at the top of the bottle body. The double-layered design, with its impact-resistant outer layer and low-temperature-resistant inner layer, prevents ice crystal formation during temperature fluctuations, thus avoiding impact on the microorganisms inside the bottle. Simultaneously, the protective mechanism prevents external oxygen from entering the bottle, preventing oxidation of the microbial agent and degradation of active ingredients, thereby ensuring the stability of the storage bottle during use.

[0027] The container includes an outer storage bottle 101 and an inner storage bottle 102. The inner storage bottle 102 is fixedly inserted into the inner wall of the outer storage bottle 101. A filling structure, including nano-aerogel 301, is provided between the outer storage bottle 101 and the inner storage bottle 102. The outer storage bottle 101 and the inner storage bottle 102 are hollow, and the nano-aerogel 301 is filled between them. The outer storage bottle 101 is made of polycarbonate, and the inner storage bottle 102 is made of borosilicate glass. The polycarbonate outer storage bottle 101 has good impact resistance, and the borosilicate glass inner storage bottle 102 has... Excellent low-temperature resistance; simultaneously, the space between the outer storage bottle 101 and the inner storage bottle 102 is vacuum-sealed and filled with nano-aerogel 301. Nano-aerogel 301 effectively blocks external temperature fluctuations such as high-temperature exposure or low-temperature freezing, maintaining a constant temperature inside the bottle and preventing the bacterial agent from becoming inactive due to sudden temperature changes. The vacuum environment almost completely eliminates gas heat transfer. Working synergistically with nano-aerogel 301, it provides excellent thermal insulation between the outer storage bottle 101 and the inner storage bottle 102, making it less prone to ice crystal formation during temperature fluctuations and preventing damage to the microbial cell membranes inside the storage bottle. The density of nano-aerogel 301 is only 3-150 kg / m³. 3 It can withstand high pressure, buffer vibration or compression during transportation, and prevent the inner bottle from breaking. At the same time, the nano aerogel 301 supports the storage outer bottle 101 and the storage inner bottle 102, avoiding deformation due to the pressure difference between the inside and outside of the storage outer bottle 101 and the storage inner bottle 102.

[0028] The functional structure includes a slow-release membrane 401, which is coated and disposed on the inner wall of the storage inner bottle 102. The slow-release membrane 401 is made of a mixture of sodium alginate and mannitol, and its thickness is 50-100 micrometers. The slow-release membrane 401 is formed on the inner wall of the storage inner bottle 102 by spraying. Sodium alginate is a natural polysaccharide that forms a hydrophilic three-dimensional network structure after dissolving in water. When the membrane is sprayed, this network can absorb and lock in moisture, while slowly releasing moisture through hydrogen bonds and capillary action. The porous structure of the gel allows moisture to diffuse at a controllable rate, avoiding rapid evaporation or leakage. The slow-release membrane 401 provides a continuous humidity environment for the microbial agent. Mannitol is a small molecule polyol with strong hydration capacity. It can adsorb moisture in the environment or retain moisture inside the membrane, delaying membrane drying. Mannitol may form a microcrystalline structure in the membrane and gradually release water when dissolved, further extending the moisturizing time. Sodium alginate provides a macroscopic slow-release framework, while mannitol fills the microscopic moisture regulation. The combination of the two achieves a more precise slow-release effect. Both materials are non-toxic to microorganisms and may provide carbon sources, such as mannitol, which can be utilized by some bacterial species, indirectly supporting the activity of the microbial agent. Thus, the slow-release membrane 401 can slowly release water to maintain the rehydration activity of the microbial agent.

[0029] The adsorption structure includes an adsorption block 501, which is located at the bottom of the inner cavity of the storage bottle 102. The adsorption block 501 contains composite particles of manganese dioxide and activated carbon. The activated carbon has a high specific surface area and porous structure, which can physically adsorb harmful gases such as ethylene, hydrogen sulfide, and ammonia that are metabolized by microorganisms or seeped into the environment, thus preventing these gases from accumulating and inhibiting the activity of the bacterial community or causing bacterial cell decay. As a catalyst, manganese dioxide can oxidize reducing gases such as ethylene and H2S into harmless products such as CO2, H2O, or sulfates. It is especially important for the removal of ethylene. Moreover, in the humid environment inside the storage bottle 102, manganese dioxide can slowly react with oxygen, thereby reducing the oxygen concentration inside the storage bottle and preventing the bacterial agent from oxidizing and losing its effectiveness. At the same time, the activated carbon can also adsorb excess moisture inside the storage bottle, preventing moisture accumulation and resulting in local high humidity, thus preventing the bacterial agent from clumping or becoming moldy.

[0030] The protective mechanism includes a bottle opening 201, a top cover 202, and a one-way valve 203. The bottle opening 201 is fixedly connected to the top of the inner storage bottle 102. The top cover 202 is fitted onto the outer wall of the bottle opening 201. The one-way valve 203 is installed on the outer wall of the top cover 202. By setting the one-way valve 203, the air intake channel is automatically closed by the air pressure difference when the cover is opened, which can prevent oxygen from entering the storage bottle and prevent the bacterial agent in the storage bottle from contacting oxygen and causing degradation of active ingredients, thereby improving the protective effect of the storage bottle on the microbial agent. A silicone sealing ring is set inside the top cover 202 so that the top cover 202 can seal the inside of the storage bottle after it is placed on the bottle opening 201.

[0031] When using the storage bottles, dispense 100 grams of bacterial powder into each bottle, then evacuate the storage bottles to a vacuum level of less than 10 Pa and close the one-way valve 203.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
