Description

Technical Field

[0001] The invention relates to the field of freeze-drying bottles, and in particular to a freeze-drying bottle with a sealing member spirally installed and an assembly method thereof. Background Art

[0002] Vacuum freeze-drying technology originated in the 1920s. Due to the limitations of vacuum and refrigeration technology at that time, it was not used for freeze-drying of biological samples until the 20th century. In recent decades, vacuum freeze-drying technology has developed rapidly. Products from agriculture, forestry, animal husbandry, sideline production, fishery and other livelihood industries can all use this technology to make freeze-dried foods, condiments, instant foods, etc., providing reliable storage guarantees for life science research, drug development and production, food production and preservation. In recent years, vacuum freeze-drying technology has been widely used in the research and manufacturing of biological products, enzymes, medicines, foods and microorganisms, especially in the drying of heat-labile samples. It is an indispensable technical means. Vacuum freeze-drying technology is used to concentrate and dry biological samples, drug samples and biological extracts, water-soluble intermediates in chemical synthesis, while removing water from the samples well, it can also maintain the integrity of the sample components. The application range of vacuum freeze-drying technology is extremely wide. Any water-containing, non-toxic and non-corrosive items can be made into dried products using freeze-drying technology. This technology has unique advantages, such as : The items are not easily oxidized, their biological, chemical structure, activity and physical properties remain basically unchanged, the composition of the items is stable, and the activity of the items is protected to the greatest extent; it can best maintain the original properties of the items; it can remove more than 95% of the moisture in the items, which is conducive to the long-term preservation of the items; it preserves the physical, chemical and biological properties of the items to the greatest extent; the external vacuum freeze dryer is in a vacuum state, and the sample bottles of low-temperature frozen samples can be connected to the outside of the freeze-drying chamber. The samples can be loaded or unloaded at any time through the sample valve on the freeze-drying chamber. The water and other solvents in the low-temperature frozen samples are converted directly from solid to gas through sublimation without passing through the liquid state. The water is condensed and discharged through the cold trap collector, and what remains in the sample bottle is a complete concentrated dry sample; it is convenient for the immediate need to dry water-containing products in scientific research work; the use of this instrument to freeze-dry various water-soluble samples to be dried basically replaces the rotary evaporation process of water contained in water-soluble intermediates in the process of chemical synthesis of drugs, improves the efficiency of the synthesis work, and greatly saves the time spent by scientific researchers in the rotary evaporation process.

[0003] Currently, the body of a freeze-drying bottle is made of glass and the bottle cap is made of rubber. When in use, the glass bottle mouth needs to be inserted into the groove of the rubber outer cap with force. The metal or glass connecting tube and the rubber bottle cap are also inserted and connected, and force is required to ensure that these parts are properly spliced. When inserting with force, deviation and slippage are likely to occur, causing the freeze-drying bottle to fall or even break. Summary of the Invention

[0004] The purpose of the present invention is to provide a freeze-drying bottle with a spiral seal and an assembly method to solve the above problems.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] refer to Figures 1 to 5, a sealing screw-mounted freeze-drying bottle, comprising a bottle body 1 and a bottle cap 5, wherein the bottle body 1 is provided with an external thread 2 for threaded connection with the internal thread 6 on the bottle cap 5, the bottle cap 5 is provided with an internal thread 6 and a connecting pipe 7, the connecting pipe 7 is used to communicate with an external vacuum freeze dryer, so that the dry cold air of the external vacuum freeze dryer enters the freeze-drying bottle, characterized in that: a buckle 9 is provided in the cavity of the bottle body 1, for positioning a dryness indicating tube 8 in the cavity of the bottle body 1, the bottle cap 5 is provided with an internal thread 6, a dryness indicating tube 8 is provided in the cavity of the bottle body 1, for detecting the dryness and humidity in the cavity of the bottle body 1, the dryness indicating tube 8 is connected to the bottle body 1 through the buckle 9, the tube cap of the dryness indicating tube 8 is provided with a micro-hole, the external thread 2 and the internal thread 6 are matched in size to ensure that the two can be connected;

[0029] The external thread 2 includes a front end 3 and a rear end 4. The external thread 2 is located outside the bottle body 1 and is used to facilitate connection with the bottle cap 5.

[0030] The connecting tube 7 is threadedly connected to the bottle cap 5 to facilitate the disassembly and assembly of the connecting tube 7. The connecting tube 7 is connected to the cavity of the bottle body 1 and is used to allow the dry cold air of the external vacuum freeze dryer to enter the freeze-dried bottle to quickly process the product inside. The gas in the freeze-dried bottle can also be extracted, and the extracted water vapor can be liquefied and discharged by the external vacuum freeze dryer.

[0031] The external thread 2 and the internal thread 6 are both in a uniform spiral shape, so as to ensure that the two can be threadedly connected.

[0032] The front end 3 is located on the bottle body 1 close to the opening of the bottle body 1, and the rear end 4 is located on the side of the bottle body 1 away from the opening of the bottle body 1, which is used to ensure that the front end 3 is connected to the internal thread 6 first, and then the rear end 4 is connected to the internal thread.

[0033] The front end 3 is specifically made of a rigid material to ensure good stability after being connected to the internal thread 6. The rear end 4 is specifically made of a flexible material to ensure that the rear end 4 can play a sealing role after entering the internal thread 6.

[0034] The end of the front end 3 is fixedly connected to the end of the rear end 4 , and both the front end 3 and the rear end 4 are bonded to the bottle body 1 to ensure that both can be locked into the internal thread 6 .

[0035] The cross-sectional size of the rear end 4 is larger than that of the front end 3. The front end 3 and the rear end 4 match the shape of the internal thread 6 to ensure that the front end 3 can be easily locked into the internal thread 6. The rear end 4 needs to increase the force to lock into the internal thread 6. As the rear end 4 is continuously locked into the internal thread, the force required to lock the rear end 4 into the internal thread 6 becomes greater and greater, which makes it convenient to judge the locking amount of the rear end 4 and ensures that the rear end 4 is in close contact with the internal thread 6 to play a sealing role.

[0036] The bottle body 1 is made of a transparent material, which is used to facilitate observation of the product in the cavity of the bottle body 2 and the dryness indicator tube 8.

[0037] The bottle body 1 is made of environmentally friendly plastic.

[0038] The dryness indicator tube 8 is specifically a transparent porous tube filled with a color-changing dryness indicator, and is used to detect the dryness and humidity in the cavity of the bottle body 1.

[0039] A method for assembling a freeze-drying bottle with a screw-mounted seal, comprising: a freeze-drying bottle with a screw-mounted seal according to any one of claims 1 to 8

[0040] S1. First, snap the dryness indicator tube 8 into the buckle 9 of the bottle body 1 cavity, and simultaneously thread the connecting tube 7 into the bottle cap 5. During this process, the connecting tube 7 passes through the bottle cap 5, so that the connecting tube 7 is in communication with the cavity of the bottle body 1.

[0041] S2. Then place the bottle cap 5 on the bottle body 1, and then gently rotate the bottle cap 5. During this process, the front end 3 can be easily locked into the internal thread 6 of the bottle cap 5. When the front end 3 is completely locked into the internal thread 6, the rear end 4 begins to be locked. Since the size of the rear end 4 is larger than the front end 3 and the hardness is smaller, the operator needs to increase the rotational force on the bottle cap 5 when the rear end 4 is locked into the internal thread 6. When the operator continues to rotate the bottle cap 5 for more than one circle, it stops. At this time, the assembly of the freeze-dried bottle is completed.

[0042] The above embodiments are used to further illustrate the present invention, but the present invention is not limited to these specific embodiments. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be understood to be within the scope of protection of the present invention.
