The structure of the dish cover is improved to drain condensate water formed in the dish cover, so that the situation that the condensate water falling back to the petri dish to pollute the culture medium is avoided. The setting of an identification area allows collectors and experimenters to effectively distinguish the cover and body of the petri dish when they use the petri dish; and the identification of petri dishes is clear and standardized, so that the experimenters can quickly distinguish petri dishes in different areas to improve the working efficiency.

Description

NOVEL PETRI DISH LU505146

BACKGROUND OF THE INVENTION

[0001] Technical Field

[0002] The present invention relates to the technical field of petri dishes, and in particular to a novel petri dish.

[0003] 2. Description of Related Art

[0004] A petri dish is a conventional labware commonly used for the cultivation of microorganisms or cells. A traditional petri dish consists of a flat disc-shaped dish body and a dish cover. The cover simply covers the dish body.

As the cover and dish body are simply combined, the dish body is very prone to fall off during the moving process. As a result, the interior of the petri dish is polluted or the dish body is broken to interrupt research activities. In addition, it is difficult for a first operator to distinguish between the cover and dish body of the petri dish to cause improper operation and artificial contamination of the petri dish.

[0005] During the using process of the petri dish, the water in the culture medium inside the dish body and the water in the culture evaporate on the inner wall of the dish cover to form condensate water, and the condensate water is likely to fall back into the petri dish and affect the culture results.

[0006] Patent CN 112266853 A discloses an anti-pollution microbial petri dish. Although the petri dish enables condensate water to flow downwards, the condensate water that flows downwards is ultimately stored in the bottom of the dish and cannot be discharged.

BRIEF SUMMARY OF THE INVENTION

[0007] To overcome the above defects, the present invention discloses a LUS05146 novel petri dish, including a dish body and a dish cover, where flanges being convex outwards in the horizontal direction are formed in the opening edge of the dish body; grooves matched with the flanges for application are formed at the edge of the inner wall of the dish cover; and in a locked state, the flanges are inserted into the grooves.

[0008] Based on the above technical solution, the number of the flanges is at least two.

[0009] Based on the above technical solution, the inner wall surface of the dish cover is integrally a non-flat surface with a high middle and a low surrounding area.

[0010] Based on the above technical solution, the inner wall surface of the dish cover is a curved surface.

[0011] Based on the above technical solution, the inner wall surface of the dish cover is a conical surface.

[0012] Based on the above technical solution, the inner wall surface of the dish cover is a camber surface.

[0013] Based on the above technical solution, an identification area is arranged on the outer wall surface of the dish cover.

[0014] The novel petri dish has the beneficial effects that the dish body and dish cover of the petri dish are locked through the flanges and grooves, so that the problem that the dish body is likely to fall off during the moving process is avoided; and in addition, the locking structure is simple. The structure of the dish cover is improved to drain condensate water formed in the dish cover, so that the situation that the condensate water falling back to the petri dish to pollute the culture medium is avoided. The setting of the identification area facilitates LUS05146 the differentiation of different petri dishes when a large number of petri dishes are used.

DETAILED DESCRIPTION OF THE INVENTION

[0023] In order to further explain the technical means and effects adopted by the present disclosure to achieve an intended purpose thereof, the specific implementation mode, structure, characteristics and effects of the present disclosure will be described in detail below with reference to the drawings and preferred embodiments.

[0024] Embodiment 1

[0025] As shown in FIGs. 1 and 2, a novel petri dish, including a dish body (1) and a dish cover (2), where flanges (1-1) being convex outwards in the horizontal direction are formed in the opening edge of the dish body (1); grooves (2-1) matched with the flanges (1-1) for application are formed at the edge of the inner wall of the dish cover (2), and in a locked state, the flanges (1-1) are inserted into the grooves (2-1).

[0026] As shown in FIG. 7, in the unlocked state of the dish body and dish cover (as shown in A in FIG. 7), the dish body and dish cover can be opened at will; by rotating the dish body 1 in the direction indicated by the arrow in A in

FIG. 7 or rotating the dish cover 2 in the opposite direction, the flanges 1-1 of the dish body 1 will be inserted into the grooves 2-1 in the inner wall of the dish cover 2, so that locking of the dish body 1 and dish cover 2 can be realized (as shown in B in FIG. 7).

[0027] As a specific embodiment, the number of flanges 1-1 is at least two, the number of flanges shown in FIG. 5 is four, and they are distributed at the opening edge of the dish body 1 at equal intervals. Correspondingly, as shown in

FIG. 6, four grooves 2-1 are correspondingly formed in the dish cover 2.

[0028] For the petri dish with the above structure, the dish body 1 is not LUS05146 prone to fall off during the moving process, so that the culture in the petri dish is prevented from being polluted. At the same time, the locking structure of the dish body 1 and dish cover 2 is very simple, so that it is convenient to open and lock. 5 [0029] In order to solve the technical problem in the prior art that condensate water 1s likely to form on the inner wall of the dish cover and drips on the culture during the using process of the petri dish, the present application provides a specific embodiment. Specifically, as shown in FIGs. 3 and 4, the inner wall surface of the dish cover 2 1s integrally a non-flat surface with a high middle and a low surrounding area (the high middle and the low surrounding area are talked about in the direction of FIGs. 3 and 4, that is, the dish cover 2 is in an inverted state).

[0030] Although there are many non-flat structures that are high in the middle and low in the surrounding area, as a specific embodiment, as shown in

FIGs. 2 and 3, the inner wall of the dish cover 2 is a curved surface, and more specifically, the curved surface is a circular arc surface.

[0031] In addition to the curved surface, as another specific embodiment, as shown in FIG. 4, the inner wall surface of the dish cover 2 is a conical surface.

[0032] The inner wall surface of the dish cover 2 with the above two structures can both drain the condensate water that accumulates on the inner wall surface of the dish cover 2 during the using process.

[0033] Many petri dishes are used simultaneously in many experiments.

Especially in hospitals, cultures from many departments are sent to the laboratory department for cultivation and examination. In this case, in order to distinguish petri dishes with different experimental purposes, the sampler will label and LUS05146 distinguish them with a pen by applying adhesive tapes to the dish covers. The differentiation method is not standardized and accurate. In order to solve the problem, the present application provides a specific embodiment for the experimenter to label and distinguish the petri dish. Specifically, the outer wall of the dish cover 2 is provided with an identification area 2-2. Taking the application in hospitals as an example, the identification area 2-2 can be printed with markings in advance to distinguish departments, samplers, dates, and experimental categories, and then the samplers fill in specific information with a pen on the markings. During the experiment, the experimenter can easily distinguish different cultures. As another feasible solution, the identification area 2-2 can also be directly attached to the dish cover 2 with the adhesive label printed with the department, sampler, date, and experimental category, and the details will not be described.

[0034] The petri dish in the application can be made of plastics, such as

PP, PE, etc., and can be discarded directly after use.

[0035] It should be understood that although the present description is described in terms of the implementation, not every implementation includes only one separate technical solution, and such a description mode of the description is merely for the sake of clarity. A person skilled in the art should take the description as a whole, and the technical solutions in all the embodiments may be appropriately combined to form other implementations that can be understood by a person skilled in the art.
