Description

Technical Field

[0001] This utility model relates to the field of cell culture technology, specifically to a resealable, moisture-proof, and oxidation-proof dry powder cell culture medium bottle. Background Technology

[0002] Dry powder cell culture medium bottles are specially designed for storing dry powder cell culture media. These bottles are typically made of high-quality plastic or glass, offering excellent sealing, chemical resistance, and transparency to ensure the dry powder culture medium remains dry and unspoiled during storage, and to facilitate observation and handling by researchers.

[0003] Traditional dry powder cell culture medium bottles are usually single-use and sealed. Although desiccants are added during packaging, they only play a certain role during the initial packaging. Once used and opened multiple times, their protective effect is greatly reduced, providing favorable conditions for the growth of microorganisms. Microbial contamination can destroy the components of the culture medium and affect the normal progress of cell culture. To address the above problems, a dry powder cell culture medium bottle that can be opened multiple times is provided to prevent moisture and oxidation. Utility Model Content

[0004] The purpose of this utility model is to provide a resealable, moisture-proof, and oxidation-proof dry powder cell culture medium bottle to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a resealable, moisture-proof, and oxidation-proof dry powder cell culture medium bottle, comprising a storage bottle, a lower cap screwed to the bottle mouth of the storage bottle, an upper cap screwed to the top of the lower cap, a fixing plate disposed in the middle of the inner cavity of the lower cap, a rotating rod rotatably connected to the top of the fixing plate via a bearing, a rotating plate fixedly sleeved on the outside of the rotating rod, multiple storage cavities opened on the rotating plate, a baffle disposed in the middle of the inner cavity of each storage cavity, two vent holes opened at the bottom of the inner cavity of each storage cavity, the two vent holes being located on both sides of the baffle, an antioxidant and a desiccant disposed in the inner cavity of each storage cavity and located on both sides of the baffle, a through hole opened on the fixing plate, the through hole being aligned with the two vent holes at the bottom of one of the storage cavities, and a switching component disposed on the upper cap.

[0005] Preferably, a sealing ring is provided at the bottom of the inner cavity of the lower screw cap.

[0006] Preferably, the sealing ring is a rubber ring.

[0007] Preferably, both the lower and upper caps have anti-slip ridges on their outer circumference.

[0008] Preferably, the switching assembly includes a rotating column, a plug rod, a socket, a frame, a worm gear, a knob, and a worm wheel. The rotating column is rotatably connected to the middle of the upper cover via a bearing. The worm wheel is fixedly sleeved on the top of the rotating column. The plug rod is fixedly connected to the bottom of the rotating column. The socket is opened at the top of the rotating rod. The frame is set at the top of the upper cover. One end of the worm gear is rotatably connected to the front end of the inner cavity of the frame via a bearing. The other end of the worm gear extends to the rear end of the frame and is fixedly connected to the knob.

[0009] Preferably, the worm gear meshes with the worm wheel.

[0010] Preferably, the inner cavity of the insertion hole and the outer wall of the insertion rod are adapted to fit each other and are both hexagonal.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. By removing the upper cap from the lower cap, it is easy to fill the storage cavity on the rotating plate with antioxidants and desiccant. After filling with the appropriate antioxidants and desiccant, insert the rod into the insertion hole, rotate the upper cap to screw it onto the lower cap, and after removing the material from the storage bottle, tighten the lower cap onto the storage bottle. By rotating the knob, the knob drives the worm gear to rotate. Since the worm gear meshes with the worm wheel, when the worm gear rotates, it causes the worm wheel to drive the rotating column and the rod to rotate. Because the rod is inserted into the inner cavity of the insertion hole and both the outer wall of the rod and the inner cavity of the insertion hole are hexagonal, when the rod rotates... When rotated, the insertion hole drives the rotating rod and rotating plate to rotate, causing the vent of the storage chamber for the already clumped antioxidant and desiccant to deviate from the through hole, and aligning the vent of the storage chamber for the fresh antioxidant and desiccant with the through hole. This maintains the dryness of the storage bottle and solves the problem that traditional dry powder cell culture medium bottles are usually single-use sealed structures. Although desiccants are added during packaging, they only play a certain role during the initial packaging. Once used and opened multiple times, their protective effect is greatly reduced, providing favorable conditions for the growth of microorganisms. Microbial contamination can destroy the components of the culture medium and affect the normal progress of cell culture. Attached Figure Description

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 4 This utility model provides a technical solution: a resealable, moisture-proof, and oxidation-proof dry powder cell culture medium bottle, comprising a storage bottle 1, a lower cap 2 screwed to the spout of the storage bottle 1, an upper cap 3 screwed to the top of the lower cap 2, a fixing plate 5 disposed in the middle of the inner cavity of the lower cap 2, a rotating rod 7 rotatably connected to the top of the fixing plate 5 via a bearing, a rotating plate 8 fixedly sleeved on the outside of the rotating rod 7, multiple storage cavities 9 opened on the rotating plate 8, a baffle 10 disposed in the middle of the inner cavity of the storage cavity 9, two vent holes 11 opened at the bottom of the inner cavity of the storage cavity 9, the two vent holes 11 being located on both sides of the baffle 10, an antioxidant and a desiccant disposed in the inner cavity of the storage cavity 9 and located on both sides of the baffle 10, a through hole 6 opened on the fixing plate 5, the through hole 6 being aligned with the two vent holes 11 at the bottom of one of the inner cavities of the storage cavity 9, a switching component disposed on the upper cap 3, by removing the upper cap 3 from the lower cap 2, thereby facilitating the filling of the storage cavities on the rotating plate 8. The inner cavity of chamber 9 is filled with antioxidants and desiccants. After filling with the appropriate antioxidants and desiccants, insert the rod 14 into the insertion hole 12, rotate the upper rotating cap so that it is screwed onto the lower rotating cap 2. After taking out the material from storage bottle 1, tighten the lower rotating cap 2 onto storage bottle 1. By switching the component settings, the rotating rod 7 and rotating plate 8 can be rotated, causing the vent hole 11 of the already clumped antioxidant and desiccant storage cavity 9 to deviate from the through hole 6, so that the vent hole 11 of the fresh antioxidant and desiccant storage cavity 9 is aligned with the through hole 6, thereby continuing to keep the storage bottle 1 dry. This solves the problem that traditional dry powder cell culture medium bottles are usually single-use sealed structures. Although desiccants are added during packaging, they only play a certain role during the initial packaging. Once used and opened multiple times, their protective effect is greatly reduced, providing favorable conditions for the growth of microorganisms. Microbial contamination will destroy the components of the culture medium and affect the normal progress of cell culture.

[0020] In this embodiment, a sealing ring 4 is provided at the bottom of the inner cavity of the lower screw cap 2, which can achieve a seal between the bottle mouth of the storage bottle 1 and the lower screw cap 2.

[0021] In this embodiment, the sealing ring 4 is a rubber ring, which has corresponding elasticity and good sealing effect.

[0022] In this embodiment, anti-slip ridges are provided on the outer circumference of both the lower cap 2 and the upper cap 3 to prevent slippage when rotating the upper cap 3 or the lower cap 2.

[0023] In this embodiment, the switching assembly includes a rotating column 13, a plug rod 14, a socket 12, a frame 15, a worm gear 16, a knob 17, and a worm wheel 18. The rotating column 13 is rotatably connected to the middle of the upper cover 3 via a bearing. The worm wheel 18 is fixedly sleeved on the top of the rotating column 13. The plug rod 14 is fixedly connected to the bottom of the rotating column 13. The socket 12 is opened at the top of the rotating rod 16. The frame 15 is set at the top of the upper cover 3. One end of the worm gear 16 is rotatably connected via a bearing. At the front end of the inner cavity of the frame 15, the other end of the worm gear 16 extends to the rear end of the frame 15 and is fixedly connected to the knob 17. After filling with the appropriate antioxidant and desiccant, insert the insertion rod 14 into the insertion hole 12, rotate the upper rotating cover to screw it onto the lower rotating cover 2, and after removing the material from the storage bottle 1, tighten the lower rotating cover 2 onto the storage bottle 1. By rotating the knob 17, the knob 17 drives the worm gear 16 to rotate. Since the worm gear 16 and the worm wheel 18 are connected... The meshing mechanism allows the worm gear 16 to rotate, causing the worm wheel 18 to drive the rotating column 13 and the insertion rod 14 to rotate. Since the insertion rod 14 is inserted into the inner cavity of the insertion hole 12 and both the outer wall of the insertion rod 14 and the inner cavity of the insertion hole 12 are hexagonal, the rotation of the insertion rod 14 causes the insertion hole 12 to drive the rotating rod 7 and the rotating plate 8 to rotate. This causes the vent hole 11 of the already clumped antioxidant and desiccant storage chamber 9 to deviate from the through hole 6, and the vent hole 11 of the fresh antioxidant and desiccant storage chamber 9 to align with the through hole 6. This helps to maintain the dryness of the storage bottle 1, solving the problem that traditional dry powder cell culture medium bottles are usually single-use sealed structures. Although desiccants are added during packaging, they only play a certain role during the initial packaging. Once used and opened multiple times, their protective effect is greatly reduced, providing favorable conditions for the growth of microorganisms. Microbial contamination can destroy the components of the culture medium and affect the normal progress of cell culture.

[0024] In this embodiment, the worm 16 meshes with the worm wheel 18, and the worm 16 and the worm wheel 18 have a self-locking effect, which can prevent the vent 11 from deviating from the through hole 6 after the new antioxidant and desiccant are switched.

[0025] In this embodiment, the inner cavity of the insertion hole 12 and the outer wall of the insertion rod 14 are adapted to each other and are both hexagonal, so that when the insertion rod 14 rotates, it drives the insertion hole 12 to drive the rotating rod 7 and the rotating plate 8 to rotate.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
