Problems solved by technology

This requires operators to have a high degree of proficiency and to be very careful, but it is still prone to the following unfavorable situations: (1) long-term operation figure 1 When the petri dish with smooth surface is prone to slipping, etc., it is easy to operate for a long time figure 2 When the petri dish is placed in the petri dish, it is easy to accidentally grab the dish cover 1 but not the hand ring 3. The consequence is that the culture in the petri dish may be pollute

[0058] Figure 7 schematically shows image 3 in the lid and Figure 5 A perspective view of a petri dish formed by the dish body in , where the petri dish is in a closed state. Figure 8 schematically shows Figure 7 Side cutaway view of a Petri dish. In the illustrated closed state, the vessel cover 10 covers the upper open space of the vessel body 20 .

[0059] In consideration of the survival of organisms in the petri dish, the inside of the petri dish and the outside of the petri dish are generally capable of air circulation. In order to realize air circulation, the commonly used method in the prior art is to arrange several protrusions at the intersection of the top wall and the side wall of the dish cover, so that the top wall of the dish cover and the end of the side wall of the dish body form between each protrusion. air channel. Different schemes are adopted in this embodiment, such as Figure 8 As shown in the enlarged part circled in the center, the sidewall...

[0086] Figure 17 It schematically shows a perspective view of a culture dish according to yet another embodiment of the present invention, wherein the culture dish is in an open state. Figure 17 Reference numeral 110 in the figure represents a dish cover, 113 represents a warped portion on the side wall of the dish cover, 120 represents a dish body, 123 represents a raised portion, and 126 represents a handle ring. The petri dish in this embodiment is square; according to the teaching of this diagram, those skilled in the art can modify it to obtain a rectangular petri dish, and further can modify it to obtain other polygonal petri dishes.

[0087] As shown in the figure, the end of the side wall of the vessel cover 110 is formed with a warped portion 113, and the warped portion 113 may extend along the entire circumference of the side wall of the vessel cover 110, or may be arranged only on the raised portion 123. at the corresponding location. For the setting of the tilt...

[0092] Figure 18 It schematically shows a perspective view of a culture dish according to yet another embodiment of the present invention, wherein the culture dish is in an open state. Figure 18 Reference numeral 110 represents the dish cover, 113 represents the warping portion on the side wall of the dish cover, 130 represents the dish body, 133 represents the holding ring, and 134 represents the long groove on the holding ring. The petri dish in this embodiment is square; according to the teaching of this diagram, those skilled in the art can modify it to obtain a rectangular petri dish, and further can modify it to obtain other polygonal petri dishes.

[0093] As shown in the figure, the end of the side wall of the vessel cover 110 is formed with a warped portion 113 . It should be noted that, in this embodiment, the warping portion 113 is only provided at a position corresponding to the long groove 134 , instead of extending along the entire circumference of the side wa...

Abstract

The invention relates to a culture dish. The culture dish comprises a culture dish body. The culture dish body comprises a bottom wall and a lateral wall extending along the periphery of the bottom wall. The bottom wall and the lateral wall form an upper opened space, which is suitable for accommodating a culture. The culture dish also comprises a culture dish cover. The culture dish cover comprises a top wall and a lateral extending along the periphery of the top wall. The culture dish cover can cover the upper opened space from a position above the culture dish body. A first locking part is formed on the lateral wall of the culture dish cover. A second locking part is formed on the lateral wall of the culture dish body. When the first locking part and the second locking part are locked by each other, the culture dish cover is opened in a specific angle relative to the culture dish body. The provided culture dish has the advantages that the culture dish can be placed on a workbench during the process of long term operation in an open state, the operation stability is improved, the size of the opening of the culture dish cover is guaranteed, at the same time, the left hand of a user is freed, and the user can use his left hand and right hand to carry out pipetting or other operations.

Description

technical field [0001] The invention relates to the technical field of cell or microorganism culture; in particular, the invention relates to a petri dish which is easy to operate. Background technique [0002] As containers for culture media, petri dishes have been used for decades in the field of cell or microbial culture technology and are often used in laboratories. Petri dishes are usually round and consist of a body containing the medium and a matching lid. The dish cover is placed on the dish body, which can prevent the medium from being polluted by microorganisms in the external environment, and at the same time allow air to pass through to facilitate the survival, growth, observation and detection of cells or microorganisms. Materials for making petri dishes include glass, synthetic resins, quartz, and corrosion-resistant metals (rarely used). [0003] figure 1 and figure 2 There are two existing common petri dish structures. [0004] figure 1 The culture dis...
