Description

petri dish

technical field

The utility model relates to the field of containers, in particular to a petri dish for cultivating microorganisms.

Background technique

U.S. Patent (patent No. is: 5021351) discloses a kind of vessel, and its structural feature is: the cross-section of vessel cover is trapezoidal, is certain angle between the rib on the vessel cover and the outer wall of vessel body, and its deficiency is: The seal between the dish cover and the dish body is not good, and it is inconvenient to lift the dish cover and the dish body together, especially inconvenient to turn the dish cover and the dish body upside down to facilitate microbial cultivation.

Contents of the invention

The purpose of this utility model is to solve the defects of the above-mentioned prior art, and to provide a petri dish which is simple in structure and easy to take and place.

The technical scheme adopted by the utility model. This petri dish mainly includes a dish body and a dish cover, wherein the dish body and the dish cover respectively include a dish body bottom wall, a dish cover bottom wall, and a dish body side wall and a dish cover extending from the outer circumference of the bottom wall. The side walls are respectively formed with openings of the dish body and the opening of the dish cover. After the dish body and the dish cover are closed, an airtight accommodating cavity is formed between the two, so that microorganisms can be cultured. The dish body and the dish cover can be perfectly circular, oval, square, pentagonal, hexagonal or any other suitable shape. Wherein, a circular ring is arranged on the outer surface of the side wall of the dish, and the size of the circular ring is convenient for the experimental operator to touch the circular ring with the mother finger and index finger or middle finger with one hand and lift it up together. It is advisable for the dish body and the dish cover to turn over the dish body and the dish cover even with the ring as the focus point. Generally, the outer diameter of the ring needs to be greater than or equal to the outer diameter of the side wall of the vessel cover.

The beneficial effect of the utility model is: because the outer surface of the side wall of the dish body is provided with a circular ring roughly in the middle, the ring has a function similar to a handle, thereby solving the problem of inconvenient lifting of the dish body and the dish cover at the same time problem; and it is also convenient to turn the dish body and the dish cover upside down with the ring as the focus point, so as to facilitate the cultivation of microorganisms.

Description of drawings: dish cover 1, dish cover bottom wall 1-1, dish cover side wall 1-2, dish cover opening 1-3, dish body 2, ring 2-1, dish body bottom wall 2-2, dish Body side wall 2-3, dish body opening 2-4, accommodating cavity 2-5.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further introduced: this petri dish mainly comprises dish body 2 and dish lid 1 that are made by transparent material, and wherein, dish body 2 and dish lid 1 have dish body bottom wall 2-2 respectively , the dish cover bottom wall 1-1 and the dish body side wall 2-3 and the dish cover side wall 1-2 extending vertically upward from the outer periphery of the bottom wall, so the dish body 2 and the dish cover 1 are respectively formed with a dish body opening 2 -4 and lid openings 1-3. . After the dish body 2 and the dish cover 1 are closed, an airtight accommodating cavity 2-5 is formed between the two, so that microorganism culture can be carried out. In order to facilitate the experimenter to open the dish cover 1 with one hand, the inner diameter of the side wall 1-1 of the dish cover is slightly larger than the outer diameter of the side wall 2-3 of the dish body, so that there is a loose fit between the dish body 2 and the dish cover 1. In order to keep the receiving chamber 2-5 sealed, the upper edge of the side wall 2-3 of the dish body and the inner surface of the bottom wall 1-1 of the lid of the dish need to be flat, so that after the body 2 and the lid 1 are closed, the side wall of the body of the dish will be flat. There is no gap between the upper edge of 2-3 and the inner surface of the lid bottom wall 1-1. The dish body 2 and the dish cover 1 can be in a perfect circle, ellipse, square, pentagon, hexagon or any other suitable shape, and only a perfect circle is drawn as a preferred technology in the diagram of this patent application plan. The most important technical feature of the utility model is that a circular ring 2-1 is arranged at the roughly middle part of the outer surface of the side wall 2-3 of the dish body. Touch the ring 2-1 with your thumb and forefinger or middle finger and lift the vessel body 2 and the vessel cover 1 together, even use the circle 2-1 as the force point to turn over without opening the vessel body 2 and the vessel cover 1 The dish body 2 and the dish cover 1 are advisable. In a preferred technical solution, the outer diameter of the ring 2-1 needs to be greater than or equal to the outer diameter of the side wall 1-2 of the vessel lid. In order to prevent the "lifting" of the bottom wall 1-1 of the lid due to the side wall 1-2 of the lid touching the ring 2-1, the inner surface of the bottom wall 1-1 of the lid cannot be in contact with the side wall 2-1 of the bowl body. The upper edge of 3 is sealed and combined, and there is a certain gap between the lower edge of the side wall 1-2 of the dish cover and the upper surface of the ring 2-1 (shown in Figure 7). When in use, the experimenter only needs to pinch the outer diameter of the ring 2-1 with the thumb and forefinger or middle finger with one hand, and can put the lid 1 and the body 2 together without opening the lid 1 and the body 2. Pick up and even turn the dish cover 1 and dish body 2 upside down with the outer diameter of the ring 2-1 as the focus point, so the operation is very convenient.
