Description

Technical Field

[0001] The utility model relates to the field of culture dishes, in particular to a plastic culture dish that is easy to hold. Background Art

[0002] A culture dish is a laboratory ware used for culturing microorganisms or cells, consisting of a flat disc-shaped bottom and a cover, usually made of glass or plastic. The materials of culture dishes are basically divided into two categories, mainly plastic and glass. Glass culture dishes can be used for culturing plant materials, microorganisms, and adherent cultures of animal cells. Plastic culture dishes may be made of polyethylene, and there are disposable and reusable ones, which are suitable for operations such as inoculation, streaking, and separating bacteria in the laboratory and can be used for culturing plant materials.

[0003] Currently, circular culture dishes are widely used in microbiology laboratories or animal and plant tissue culture operations. Such circular culture dishes have the following disadvantages: it is very inconvenient to conduct comparative experiments on bacteria and animal and plant tissues because the interior of the culture dish cannot be partitioned; in most cases, when an operator pours the culture medium into the culture dish, it is impossible to ensure the consistency and uniformity of the thickness of the culture medium. At this time, the operator will hold the culture dish and shake it back and forth until the culture medium seems to have the same thickness around. However, since most culture dishes are circular and made of glass or plastic, the culture dish may slip out of the hand during the shaking process, affecting the accuracy of the experimental results. Therefore, we propose a plastic culture dish that is easy to hold. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , an easy-to-grip plastic Petri dish, including a Petri dish lid 1, a Petri dish 2 and an easy-to-grip component 3. The bottom end of the Petri dish lid 1 is connected to the Petri dish 2, and an anti-slip ring 9 is provided on the upper end of the Petri dish lid 1. A spacer 10 is installed inside the Petri dish 2. A positioning opening 6 is provided on the outer side of the Petri dish 2, and the Petri dish 2 is connected to the easy-to-grip component 3 through the positioning opening 6 provided on the first positioning plate 5. A second positioning plate 7 is provided inside the easy-to-grip component 3, and an anti-slip sheet 13 is provided on the outside.

[0025] Furthermore, the Petri dish lid 1 is a transparent plastic shell. An anti-slip structure 4 is provided on the outer surface of the Petri dish lid 1. Positioning blocks 14 are evenly distributed around the inner wall of the Petri dish lid 1 inside the Petri dish lid 1, and a sealing ring 15 is provided inside the Petri dish lid 1.

[0026] Furthermore, the Petri dish 2 is a transparent plastic container. Positioning grooves 11 are evenly distributed around the outer wall of the Petri dish 2 on the upper surface of the outer side of the Petri dish 2. A first positioning plate 5 is provided on the outer surface of the Petri dish 2. And three spacers 10 of the same size as the easy-to-grip component 3 are installed inside the Petri dish 2 to isolate the space inside the Petri dish 2. Positioning openings 6 are evenly distributed around the first positioning plate 5 on the first positioning plate 5.

[0027] Furthermore, the easy-to-grip component 3 is a transparent plastic hollow cone with its tip cut off, and a circular hollow for facilitating the installation of the Petri dish 2 is provided at the center position inside the easy-to-grip component 3.

[0028] Further, the second positioning plate 7 is a circular plastic thin sheet, and a connecting shaft is installed above the position of the second positioning plate 7. Positioning shafts 8 evenly distributed around the connecting shaft are arranged inside the connecting shaft, and rotating shafts 12 evenly distributed around the connecting shaft are arranged at the upper end of the connecting shaft. The anti-slip sheet 13 is a circular plastic thin sheet obliquely installed on the rotating shaft 12.

[0029] Further, the rotating shaft 12 is a rotatable movable plastic dial, and when the rotating shaft 12 rotates above the positioning shaft 8, the anti-slip structure 4 on the dish cover 1 is in frictional contact with the rotating shaft 12.

[0030] Further, the anti-slip ring 9 is a circular fixed thin ring respectively fixed to the upper end of the dish cover 1 and the lower end of the culture dish 2, and an extended thin sheet of the spacer 10 is arranged at the center position of the lower end of the culture dish 2.
