Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of container sealing, in particular to a glass bottle rubber stopper fixing and air pressure balancing device. Background Art
[0002] In the pharmaceutical and biological products industries, there are many solutions that need to be stored under sterile conditions, and their containers are mostly glass bottles or plastic bags. When glass bottles are used, the following factors may cause the solutions to be contaminated by microorganisms and become scrapped.
[0003] For some solutions that require high-temperature sterilization, the internal temperature and pressure change dramatically before and after sterilization. The thermal expansion and contraction of the solution and the bottle may cause the stopper seal to fail.
[0004] During the sterilization process (116-121°C) and when the pressure is released after sterilization is completed, the solution in the glass bottle will boil violently, pushing up the rubber stopper or even breaking the stopper and gushing out.
[0005] Or when a glass bottle containing a large amount of solution is being transported, the liquid inside shakes, causing the pressure change and loosening of the rubber stopper. As the rubber stopper is used for a longer time, its surface gradually ages and grooves appear, and the rubber stopper no longer fits tightly against the bottle mouth, which can easily cause sealing failure.
[0006] The use of plastic bags or plastic buckets can usually avoid the above problems to a certain extent. However, due to their material properties, general plastic bags and plastic buckets cannot withstand high temperature and high pressure sterilization (116-121°C) when filled with solutions. Glass bottles are not affected by high temperature and high pressure, so glass bottles, especially large-capacity glass bottles (generally referring to a volume of 10 to 20 liters), still have a wide range of usage scenarios. Utility Model Content
[0007] The utility model aims to provide a glass bottle rubber plug fixing and air pressure balancing device to solve the problems of loose sealing and inconvenient sealing operation in the existing glass bottle sealing technology.
[0008] The technical solution of the utility model to solve the above technical problems is as follows:
[0009] A glass bottle rubber plug fixing and air pressure balancing device, comprising a bottle body, a rubber plug arranged on the top of the bottle body, and a fixing component for fixing the rubber plug on the top of the bottle body, wherein a pressure balancing component is inserted on the top of the rubber plug;
[0010] The fixing assembly comprises a clamping hoop arranged at the bottle mouth, a pressing rod detachably connected to two ends of the clamping hoop, and a fastener movably connected to the pressing rod.
[0011] The clamp and the pressure rod adopt a detachable connection design, and the fasteners with movable connections make the fixing components easy to install and disassemble, and facilitate regular cleaning and inspection of the stopper and the bottle to ensure hygiene and safety during use.
[0012] Furthermore, the pressure balancing assembly includes an exhaust pipe connected to the rubber plug, a first flexible pipe connected to the outer end of the exhaust pipe, and an air filter connected to the outer end of the first flexible pipe.
[0013] Furthermore, the diameter of the rear end of the air filter is greater than the diameter of the front end.
[0014] Furthermore, a liquid delivery tube and a second flexible tube connected to the outer end of the liquid delivery tube are inserted into the top of the rubber plug.
[0015] Furthermore, a sealing member for sealing the liquid delivery pipe is provided at the outer end of the liquid delivery pipe.
[0016] Furthermore, the lower end of the liquid delivery tube is arranged in the bottle body, and a second flexible tube is arranged at the bottom of the liquid delivery tube.
[0017] Furthermore, a circular gasket is provided between the clamp and the pressure rod.
[0018] Furthermore, the shape of the pressure rod is a concave structure.
[0019] The utility model has the following beneficial effects:
[0020] The utility model can automatically adjust the gas flow and keep the pressure inside the bottle stable when the pressure inside and outside the bottle changes through the pressure balance component (including the exhaust pipe, the first flexible tube and the air filter), thereby enhancing the sealing effect between the rubber plug and the bottle mouth to prevent leakage. It is particularly suitable for storing volatile liquid products or liquid products with high sealing requirements. At the same time, the addition of the circular gasket further balances the force and protects the bottle body from damage. The special design of the air filter (the diameter of the rear end is larger than the front end) helps to filter impurities in the air more efficiently. At the same time, when used in combination with the silicone tube, the device can be used in occasions where it is necessary to control gas exchange or maintain a specific gas environment, which increases the flexibility of application.

Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0025] Please refer to Figure 1-2 The utility model provides a glass bottle stopper fixing and air pressure balancing device, wherein a bottle body 1 serves as a basic container, and an opening for receiving the stopper is preset on the top. The stopper 2 has a size that fits the opening of the bottle body, and an interface for a pressure balancing component is provided on the top. The fixing component includes a clamp 3 arranged at the bottle mouth, a pressure rod 4 detachably connected to both ends of the clamp 3, and a fastener 5 movably connected to the pressure rod 4. The clamp 3 is installed on the top of the bottle body, close to the edge of the bottle mouth, and is used to fix the pressure rod. Both ends of the pressure rod 4 are detachably connected to the two ends of the clamp, and a concave structure is adopted to enhance the contact stability with the clamp and the fastener. The fastener 5 is movably connected to the pressure rod, and is used to adjust the pressure applied by the pressure rod to the stopper to ensure the stability of the stopper.
[0026] Please refer to Figure 1 The pressure balance assembly includes an exhaust pipe 11 connected to the rubber plug 2, a first flexible pipe 12 connected to the outer end of the exhaust pipe 11, and an air filter 7 connected to the outer end of the first flexible pipe 12. The exhaust pipe 11 is connected to the top of the rubber plug as a pressure conduction channel. The first flexible pipe 12 is connected to the outer end of the exhaust pipe 11 to provide a flexible connection. The air filter 7 is located at the outer end of the first flexible pipe 12, and its rear end diameter is larger than the front end, which is conducive to gas circulation and filtering of external impurities.
[0027] Please refer to Figure 1-2 , a liquid delivery tube 13 is also inserted at the top of the rubber plug 2, and a seal 6 for sealing the liquid delivery tube 13 is provided at the outer end of the liquid delivery tube 13. The lower end of the liquid delivery tube 13 is arranged in the bottle body 1, and a second flexible tube 14 is arranged at the bottom of the liquid delivery tube 13. The liquid delivery tube 13 is inserted into another interface at the top of the rubber plug 2, and is equipped with a seal 6 to provide a way for liquid to enter and exit the bottle body. The seal 6 can be a sealing clamp. The second flexible tube 14 is arranged at the bottom of the liquid delivery tube 13 to facilitate the inflow and outflow of liquid in the bottle. The circular gasket is placed between the clamp and the pressure rod to expand the contact area between the pressure rod 4 and the rubber plug 2, so that the pressure rod 4 continuously applies downward pressure to the rubber plug 2 to fix it firmly. The first flexible tube 12 and the second flexible tube 14 can be silicone tubes.
[0028] Working principle: When in use, first assemble the rubber plug 2 to the top of the bottle body 1, then adjust the fastener 5 through the combination of the clamp 3 and the pressure rod 4 to apply appropriate pressure to the rubber plug to ensure sealing. The pressure balance component allows external gas to adjust the pressure in the bottle through the air filter 7, while the liquid delivery tube 13 and the second flexible tube 14 facilitate the inflow and outflow of the liquid in the bottle. After removing the seal 6, connect the infusion pipeline to the liquid delivery tube 13, take another section of hose, connect one end to the air filter 7, and the other end to the vacuum pump. When the vacuum pump applies positive pressure, the liquid in the bottle is pumped out, and when the vacuum pump applies negative pressure, the liquid elsewhere is sucked into the bottle.
[0029] The present embodiment provides a sealing cover structure suitable for use in large-capacity glass bottles, suitable for high-pressure steam sterilization and aseptic storage, which can ensure that the rubber stopper is loosened due to thermal expansion during sterilization, and can also avoid loosening of the rubber stopper due to changes in internal air pressure during storage.
