Description

Technical Field

[0001] This utility model relates to the field of cell culture technology, and in particular to a cell culture dish and its storage support frame. Background Technology

[0002] A petri dish is a small, shallow, transparent, covered container, mainly consisting of a flat, round dish body and a lid. It is used to hold culture media and for culturing microorganisms in an incubator. Primarily used in biological experiments for cell or microbial culture, petri dishes are widely used in experiments and teaching in fields such as medicine, microbiology, and biomedicine due to their ease of use. For example, in microbiology experiments, petri dishes are used to hold growth media to cultivate microorganisms. Named after its inventor, the German bacteriologist Julius Richard Petri, it is also known as a Petri dish or culture plate.

[0003] Most cell culture dishes available on the market are typically placed directly on a table or in an incubator during use. In this case, the cell culture dishes are prone to displacement or even tipping over if subjected to external force. Alternatively, to save space inside the incubator, two or more cell culture dishes are stacked on top of each other. Stacked cell culture dishes are also prone to tipping over if subjected to external force. In addition, during experimental culture, the lids need to be opened frequently to add liquid, and the opening of the lids can easily cause the dishes to collide and tip over. Therefore, all of the above phenomena can easily lead to the spillage of materials from the cell culture dishes, affecting the normal operation of cell culture. Utility Model Content

[0004] In order to solve the problems of poor stability of existing cell culture dishes, which are easy to tip over during use and cause the culture medium to spill, this utility model discloses a cell culture dish and its storage support frame.

[0005] The specific technical solution of this utility model is as follows:

[0006] This utility model provides a cell culture dish, including a dish body for holding culture medium and a dish lid disposed above the dish body. The inner diameter of the dish lid is larger than the diameter of the dish body. The downward-extending sidewall of the edge of the dish lid is provided with a vent hole, and the upward-extending sidewall of the edge of the dish lid forms an annular cavity. The top sidewall of the dish body is provided with a vent groove, and the bottom sidewall of the dish body extends downward to form a support structure.

[0007] In some embodiments, the lid is further defined as having a metal sheet embedded in its top, and also includes an adsorption component, which includes a magnetic sheet and a ring disposed above the magnetic sheet, the magnetic sheet being adsorbed and connected to the metal sheet.

[0008] In some embodiments, the ring edge is further defined as having a connecting rod, the end of the connecting rod away from the ring being connected to a rotating ball, the magnetic plate having a spherical groove, the rotating ball being engaged in the spherical groove and being able to rotate within the spherical groove.

[0009] In some embodiments, the outer wall of the dish is further provided with an anti-slip structure, which is symmetrically arranged on the outer wall of the dish.

[0010] Preferably, the anti-slip structure is a frosted layer or a serrated ring.

[0011] Preferably, the vessel body and the vessel lid are made of polystyrene.

[0012] This utility model also provides a storage support rack for stacking the cell culture dishes, including an annular base and an annular top. Both the annular base and the annular top are provided with cross supports. The annular base and the annular top are connected by three longitudinal support rods, wherein the distance between two adjacent support rods is greater than the outer diameter of the dish cover, and the distance between the remaining adjacent support rods is less than the outer diameter of the dish cover.

[0013] Preferably, a handle is connected above the top of the annular frame.

[0014] The beneficial effects of this utility model are as follows: The cell culture dish structure provided by this utility model has a unique design, making it more stable when stacked and preventing spillage. In addition, when cell culture dishes are shaken and mixed on the table, the bottom of the dish is easily rubbed. The support structure design at the bottom of the dish can effectively reduce bottom friction and ensure the transparency of the dish for easy observation. Furthermore, this utility model also provides a storage support rack for fixing stacked cell culture dishes, ensuring the stability of the cell culture dishes during transfer, culture, sterilization and other processes, making it highly practical.

[0025] The present invention will be further described in detail below with reference to the following embodiments.

[0026] like Figure 1-8 As shown, this utility model provides a cell culture dish, including a dish body 10 for holding culture medium and a dish lid 20 disposed above the dish body 10. Both the dish body 10 and the dish lid 20 are designed with transparent materials to facilitate observation of the cell culture process during the culture process.

[0027] like Figure 1-2 As shown, the inner diameter of the lid 20 is larger than the diameter of the dish body 10, allowing the lid 20 to be directly attached to the dish body 10. The downward-extending sidewall of the lid 20 has ventilation holes 21, while the upward-extending sidewall forms an annular cavity 22. The top sidewall of the dish body 10 has a ventilation groove (not shown in the figure), and the bottom sidewall of the dish body 10 extends downward to form a support structure 11. The ventilation groove can be a micro-groove, as long as it allows for ventilation. The ventilation groove and ventilation holes 21 enable gas flow and exchange, ensuring the oxygen and carbon dioxide required during cell culture. Simultaneously, the ventilation holes 21 on the side of the lid 20 prevent contamination of the culture medium. The annular cavity 22 above the lid 20 ensures stability when multiple cell culture dishes are stacked. The bottom of the dish body 10 of the stacked cell culture dishes can extend into the annular cavity 22, ensuring stability and preventing slippage.

[0028] like Figure 2As shown, the support structure 11 at the bottom of the dish 10 can be a ring-shaped support base. After the culture medium is placed in the cell culture dish and inoculated, it is necessary to shake the culture medium to mix it. The existing cell culture dish 10 is directly moved horizontally on the table to mix it, which will cause friction at the bottom of the dish 10. The design of the support structure 11 can not only achieve horizontal movement and mixing, but also prevent friction at the bottom of the dish 10, ensuring that the bottom of the dish 10 remains transparent after multiple uses.

[0029] like Figure 2-4 As shown, in some embodiments, the top of the lid 20 is further defined as having a metal sheet 23 embedded within it. The metal sheet 23 can also be replaced with one embedded with metal powder. An adsorption component is also included, comprising a magnetic sheet 24 and a finger ring 25 positioned above the magnetic sheet 24. The magnetic sheet 24 is adsorbed onto the metal sheet 23. When the lid 20 needs to be opened frequently, the operator's hand can easily slip due to the smooth surface of the lid 20. Therefore, when the lid 20 needs to be opened, an adsorption component can be provided on the lid 20. When not in use, it can be removed. The magnetic sheet 24 of the adsorption component is magnetically attracted to the metal sheet 23. The operator's finger is placed on the finger ring 25, facilitating the opening of the lid 20, making it extremely convenient to use.

[0030] like Figure 5-6 As shown, in some embodiments, the ring 25 is further defined with a connecting rod 26 on its edge. A rotating ball 27 is connected to the end of the connecting rod 26 away from the ring 25. A spherical groove 28 is provided on the magnetic plate 24, and the rotating ball 27 is engaged within the spherical groove 28 and can rotate within it. The ring 25 can achieve a rotatable connection with the metal plate 23 via the rotating ball 27, facilitating changes in the angle of the ring 25 and allowing the operator to easily insert their fingers into the ring 25. When not in use, the adsorption assembly can be removed from the lid 20.

[0031] like Figure 4 As shown, in some embodiments, the outer wall of the dish 10 is further provided with an anti-slip structure 12, which is symmetrically arranged on the outer wall of the dish 10. During the experiment, the dish 10 is frequently picked up and put down, and the anti-slip structure 12 on the dish 10 can effectively increase friction and prevent the cell culture dish from tipping over or the liquid from spilling.

[0032] Preferably, the anti-slip structure 12 is a frosted layer or a serrated ring. Both the frosted layer and the serrated ring design provide an anti-slip effect, effectively preventing the operator from experiencing operational instability due to the size difference between the outer diameter of the lid 20 and the outer diameter of the dish body 10 during the placement, grasping, opening, or moving of the cell culture dish, which could lead to the dish body 10 filled with culture medium spilling or even falling.

[0033] Therefore, preferably, the material of the dish body 10 and the dish lid 20 is polystyrene, but it can also be glass, depending on the need.

[0034] like Figure 7 As shown in Figure 8, this utility model also provides a storage support rack for stacking the cell culture dishes, including an annular rack bottom 31 and an annular rack top 32. Both the annular rack bottom 31 and the annular rack top 32 are provided with cross brackets 33. The annular rack bottom 31 and the annular rack top 32 are connected by three longitudinal support rods 34, wherein the distance between two adjacent support rods 34 is greater than the outer diameter of the dish cover 20, and the distance between the remaining adjacent support rods 34 is less than the outer diameter of the dish cover 20. When researchers culture, store, or transfer cells, they can place stacked cell culture dishes on a storage support rack. Of the three support rods 34, only the distance between two adjacent support rods 34 is greater than the outer diameter of the dish lid 20, which can be used as the entrance and exit for placing and removing cell culture dishes. The distance between the remaining adjacent support rods 34 is less than the outer diameter of the dish lid 20, which can be used to limit the placement of the culture dishes and ensure their stability. The storage support rack can be used to place stacked cell culture dishes in an incubator for culture, to sterilize stacked cell culture dishes, or to transfer them, preventing the cell culture dishes from tipping over and ensuring the stability of the cell culture dishes during the stacking process.

[0035] Preferably, a carrying handle 35 is connected above the top of the annular frame 32. The carrying handle 35 can be a wristband, a hook, etc., making it more convenient and easier to use.

[0036] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
