Description

Technical Field

[0001] This utility model relates to the field of petri dish technology, and in particular to a foldable biological petri dish. Background Technology

[0002] Foldable culture dishes are biological culture containers made of flexible materials or with special structural designs that can change their shape or volume as needed. Their core feature, which distinguishes them from traditional rigid (such as glass or hard plastic) culture dishes, is their ability to deform.

[0003] Traditional biological culture dishes are mostly rigid, one-piece structures, which have problems such as large space occupation, high transportation costs, and poor stacking stability. Existing foldable culture dishes are mostly made of flexible materials, but they have problems such as insufficient sealing and poor mechanical strength. Therefore, we propose a foldable biological culture dish. Utility Model Content

[0004] In view of the problems of existing rigid culture dishes being non-foldable and flexible culture dishes having insufficient performance, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A foldable biological culture dish includes a base plate, the base plate being foldably connected to a movable plate via a folding piece, the base plate being also sealed to the movable plate via a sealing structure, and the sealing structure being installed on the edge of the base plate and the movable plate.

[0007] The folding plate has a flexible V-shaped structure. One end of the folding plate is fixedly installed on the base plate, and the other end of the folding plate is fixedly installed on the movable plate, so as to realize the folding function of the petri dish, significantly reduce the space occupation when not in use, and at the same time take into account the airtightness requirements after folding to avoid culture medium leakage or contamination.

[0008] As a technical solution of the foldable biological culture dish of this utility model, magnetic rings are installed on both the base plate and the movable plate. When in the unfolded state, the magnetic rings are attracted and fixed to the positioning groove on the matching incubator, so as to improve the operational stability and positioning accuracy, and are especially suitable for batch operation scenarios in the laboratory.

[0009] As a technical solution of the foldable biological culture dish of this utility model, the sealing structure includes a lower convex ring edge installed on the edge of the base plate, and an annular sealing groove is provided on the top of the lower convex ring edge.

[0010] As a technical solution of the foldable biological culture dish of this utility model, the sealing structure further includes an upper convex ring edge installed on the edge of the movable dish body. The bottom of the upper convex ring edge is equipped with a deformable sealing ring corresponding to the annular sealing groove. The sealing ring is adapted to the annular sealing groove. When in the folded state, the sealing ring is compressed and deformed to form a sealing barrier, so as to significantly improve the anti-pollution ability and the reliability of long-term storage.

[0011] As a technical solution of the foldable biological culture dish of this utility model, the base plate and the movable plate are both made of transparent polystyrene, and the inner surfaces of the base plate and the movable plate are treated by plasma process to form a hydrophilic cell culture layer, so as to meet the needs of optical observation and improve the success rate of cell culture.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] 1. This utility model, through the combined design of flexible V-shaped folding sheet and sealing structure, not only achieves volume reduction after folding and reduces transportation / storage costs, but also solves the problem of insufficient sealing of flexible materials, while taking into account both mechanical strength and airtightness.

[0014] 2. This utility model, by adopting magnetic positioning and a hydrophilic culture layer design, can optimize the experimental process from two dimensions: ease of operation and cell growth environment, so as to meet the needs of modern biological experiments for high efficiency and high success rate.

[0026] Reference Figures 1-4 A foldable biological culture dish is provided, which includes a base plate 1, a movable plate 2 that is foldably connected to the base plate 1 via a folding piece 3, and the base plate 1 is also sealed to the movable plate 2 via a sealing structure, and the sealing structure is installed on the edge of the base plate 1 and the movable plate 2.

[0027] The folding plate 3 has a flexible V-shaped structure. One end of the folding plate 3 is fixedly installed on the base plate 1, and the other end of the folding plate 3 is fixedly installed on the movable plate 2. The folding plate 3 is made of silicone or TPU material, with a folding angle of 60°-90°. When unfolded, it lays flat at 180°. In application, the flexible V-shaped folding plate 3 connects the base plate 1 and the movable plate 2, realizing the foldable function of the petri dish. This significantly reduces the space occupied when not in use. At the same time, the design of the sealing structure takes into account the airtightness requirements after folding, avoiding leakage or contamination of the culture medium.

[0028] Reference Figure 1 and Figure 4 Both the base plate 1 and the movable plate 2 are equipped with magnetic rings 4 (neodymium iron boron magnetic rings, 0.5mm in diameter). When in the unfolded state, the magnetic rings 4 are attracted and fixed to the positioning groove on the matching incubator. They automatically attract when the distance between the magnetic rings 4 and the positioning groove (containing ferromagnetic material) of the incubator is ≤2mm, with a positioning deviation of <0.3mm. In application, the setting of the magnetic rings 4 enables the culture dish to be quickly attracted and fixed to the incubator in the unfolded state, improving operational stability and positioning accuracy, and is especially suitable for batch operation scenarios in the laboratory.

[0029] Reference Figures 2-4 The sealing structure includes a lower convex ring 501 (height 1.5-2mm) installed on the edge of the base plate 1. The top of the lower convex ring 501 has an annular sealing groove 502 (depth 0.8mm). The sealing structure also includes an upper convex ring 503 installed on the edge of the movable plate 2. The bottom of the upper convex ring 503 is equipped with a deformable sealing ring 504 (silicone sealing ring, circular cross-section, diameter 1.2mm) corresponding to the annular sealing groove 502. The sealing ring 504 is adapted to the annular sealing groove 502. When in the folded state, the sealing ring 504 is compressed and deformed to form a sealing barrier. The sealing ring 504 is compressed and deformed by 30%-40% to fill the annular sealing groove 502. In application, the matching design of the lower convex ring 501 and the upper convex ring 503, combined with the deformable sealing ring 504, forms a double sealing barrier through compression when folded, which significantly improves the anti-contamination ability and the reliability of long-term storage.

[0030] Reference Figures 1-4 Both the base plate 1 and the movable plate 2 are made of transparent polystyrene, which is injection molded to a thickness of 1.2mm. The inner surfaces of both the base plate 1 and the movable plate 2 are treated with plasma to form a hydrophilic cell culture layer. The inner surfaces are treated with oxygen plasma (50W power, 120 seconds) to reduce the contact angle to below 20° and form a hydrophilic layer. In application, the transparent polystyrene material meets the requirements of optical observation, and the hydrophilic cell culture layer enhances cell adhesion efficiency and improves the success rate of cell culture through plasma technology.

[0031] The working principle of this utility model is as follows: When it needs to be unfolded for use, the edge of the movable plate 2 is pinched and unfolded upward to 180°, the folding piece 3 is straightened and locked at the angle, and then the unfolded culture dish is placed in the incubator. The magnetic ring 4 automatically adsorbs the positioning groove to ensure that the base plate 1 and the movable plate 2 are horizontally fixed. Then, liquid culture medium is injected into the base plate 1, and overflow into the annular sealing groove 502 is avoided. At the same time, the movable plate 2 is closed, and the upper convex ring edge 503 is pressed to make the sealing ring 504 completely pressed into the annular sealing groove 502 to form a seal. Finally, it is placed in a 37°C, 5% CO2 incubator. The transparent material makes it easy to observe with a microscope.

[0032] When it is necessary to fold and store the petri dishes, remove the culture medium and rinse the base plate 1 and movable plate 2 with deionized water. Then, pinch the movable plate 2 and fold it down to 60°. The folding piece 3 is bent and stored, and the magnetic rings 4 attract each other to lock the folded state. Then, stack multiple folded petri dishes to reduce the height and store them in a dry environment.

[0033] This invention provides a foldable biological culture dish. The combination design of the flexible V-shaped folding plate 3 and the sealing structure not only reduces the volume after folding and lowers the transportation / storage cost, but also solves the problem of insufficient sealing of flexible materials. It also balances mechanical strength and airtightness. At the same time, the design of magnetic positioning and hydrophilic culture layer can optimize the experimental process from the two dimensions of ease of operation and cell growth environment, so as to meet the needs of modern biological experiments for high efficiency and high success rate.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
