Problems solved by technology

[0002] At present, the petri dishes, especially the disposable petri dishes used in the hospital, all include a bottom plate and a top cover with a slightly smaller diameter than the bottom plate. Several protrusions are set on the bottom surface of the inner wall of the chassis to support the top cover to prevent the top cover from being in close contact with the chassis and to make the culture dish breathable; therefore, the bottom surface of the inner wall of the chassis cannot be used to coat the culture medium to cultivate microorganisms
[0003] Because the disposable petri dish can only use the top cover as a culture place, and the bottom plate is only used as a protective device to prevent the contamination of bacteria, therefore, the utilization rate of the inner space of the petri dish is very low; and this traditional disposable petri dish is used Finally, the chassis and top cover will be discarded, which makes the defect of low utilization rate of the petri dish more prominent, increases the cost of using a disposable petri dish, and is not conducive to environmental protection and saving

Embodiment Construction

[0022] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0023] Such as figure 1 and figure 2 As shown, a petri dish includes a chassis 1 and a top cover 2 with a diameter slightly smaller than that of the chassis 1. Several protrusions 3 are arranged on the inner bottom surface of the chassis 1 near the side wall to support the side wall of the top cover 2. Prevent the top cover 2 from being in too close contact with the chassis 1, so as to increase the air permeability of the culture dish. The significant difference from the traditional culture dish is that: the inner bottom surface of the chassis 1 is also provided with a raised inner ring 4, when the top cover 2 When buckled in the chassis 1, the side wall of the top cover 2 is placed between the inner ring 4 and the side wall of the chassis 1; ...

Abstract

The invention relates to a culture dish. The culture dish comprises a base plate and a top cover the diameter of which is slightly smaller than that of the base plate, wherein the bottom surface, close to the side wall, inside the base phase is provided with a plurality of lugs; the bottom surface inside the base phase is also provided with a protruded inner ring; when the top cover is covered inthe base plate, the side wall of the top cover is arranged between the inner ring and the side wall of the base plate; and a gap is reserved between the top of the inner ring and the top surface inside the top cover, and the gap is larger than thickness of a culture medium. The culture dish is simple in structure; the inner space of disposable culture dish is fully utilized, thus the utilization rate of the disposable culture dish is improved, namely the cost is reduced, so that the culture dish is environmentally-friendly and saving; and the culture environments of the base plate and the topcover are consistent, and the interior humidity of the culture dish is constant.

Description

technical field [0001] The invention relates to an appliance used in medical experiments, in particular to a disposable petri dish. Background technique [0002] At present, the petri dishes, especially the disposable petri dishes used in the hospital, all include a bottom plate and a top cover with a slightly smaller diameter than the bottom plate. Several protrusions are arranged on the bottom surface of the inner wall of the chassis to support the top cover to prevent the top cover from being in close contact with the chassis, so that the petri dish is ventilated; therefore, the bottom surface of the inner wall of the chassis cannot be used to coat the culture medium to cultivate microorganisms. [0003] Because the disposable petri dish can only use the top cover as a culture place, and the bottom plate is only used as a protective device to prevent the contamination of bacteria, therefore, the utilization rate of the inner space of the petri dish is very low; and this t...
