The dish cover is mostly flat or slightly arc structure, and is used in cooperation with the dish bottom for the culture of microorganism, cell and other samples. In the culture process, the internal environment of the culture dish is relatively closed, and the temperature, humidity and other conditions are suitable for sample growth.

[0003] However, in the culture process, due to the change of temperature and humidity, water beads are easily formed in the dish. When the cover is opened, these water beads can flow into the culture medium, causing local dilution of nutrient components, interfering with the growth of bacterial colonies, changing the morphology of bacterial colonies, and affecting the accuracy of subsequent detection work such as separation, counting and the like. SUMMARY

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0022] In the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating the connection relationship between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a novel petri dish, including a base 1 and a lid 2, which are interlocked. The lid 2 includes an outer cover 21, a water-receiving layer 22, and a water collection hole 23. The outer cover 21 is made of glass or plastic and is used to maintain a basic closed environment of the petri dish, preventing external impurities from entering the petri dish and protecting the internal sample from external interference. A water-receiving layer 22 is provided at the bottom of the outer cover 21. The water-receiving layer 22 is made of glass or plastic, and its outer annular edge is seamlessly connected to the outer cover 21 to ensure airtightness and prevent water droplet leakage. Layer 22 is wavy, and the height of the water receiving layer 22 reaches a maximum of about 5 mm at a distance of 3 mm from the inner edge of the outer cover 21, which facilitates the flow and collection of water droplets when the plate is inverted. A water collection hole 23 is provided in the center of the ring of the water receiving layer 22. The water collection hole 23 is recessed into the outer cover 21 and is about 2 mm from the top of the outer cover 21. When the petri dish is inverted for culture, the water droplets generated inside the petri dish will be guided down through the water receiving layer 22 by gravity and collected into the cover 2 through the water collection hole 23. When the plate is upright and the cover is opened, the liquid in the cover 2 will slide into the water receiving layer 22, preventing water droplets from dripping directly onto the culture medium.

[0024] like Figure 3As shown, the water-receiving layer 22 includes a recessed area 221 in the middle and symmetrically arranged raised areas 222 on both sides. A water collection hole 23 is provided in the middle of the recessed area 221. The edges of the recessed area 221 and the raised areas 222 on both sides are rounded. The combination of the recessed area 221 and the raised areas 222 on both sides presents a wave-like shape, which facilitates the flow and collection of water droplets when inverted. At the same time, by increasing the adhesion area of ​​water droplets, the risk of water droplets gathering and dripping is reduced.

[0025] Working principle: When the petri dish is inverted for culture, the culture medium is fixed in the bottom 1 of the dish and the lid 2 is placed on top. Water droplets generated inside the petri dish will be guided down through the water receiving layer 22 by gravity and collected in the water collection hole 23 into the lid 2. When the dish is upright and the lid is opened, the outer cover 21 is opened and the liquid on the lid 2 will slide down to the raised areas 222 on both sides under the guidance of the concave area 221. The concave area 221 and the raised areas 222 on both sides increase the adhesion area of ​​the water droplets, thus preventing the water droplets from dripping directly onto the culture medium.

[0026] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
