Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of biomedical equipment, and particularly relates to a culture dish. Background Art
[0002] A culture dish is a common experimental apparatus for culturing cells, tissues or biological individuals, which consists of a flat disc-shaped or square disc-shaped bottom and a corresponding-shaped upper cover. Common materials used for making culture dishes include glass and plastic. Culture dishes made of glass can usually be reused after being sterilized by high temperature and high pressure, while culture dishes made of plastic are generally for single use. Culture dishes can meet the cultivation of microorganisms such as bacteria, fungi, protozoa, as well as cells or tissues of animals and plants, and can also be used to cultivate whole plant individuals.
[0003] In related technologies, when cultivating plants vertically, in order to simulate root shading, mainly the root part in the culture dish is wrapped with tinfoil outside the culture dish. Although the process is relatively simple, it can only partially block the light irradiating on the plant roots, and a large amount of light can still pass through the upper part of the culture dish and irradiate on the roots through the gap between the culture medium and the external tinfoil.

Detailed implementation manners
[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative efforts belong to the protection scope of the present utility model. In addition, it should be understood that the specific implementation manners described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model. In the present utility model, unless otherwise stated, the orientation words such as "upper" and "lower" generally refer to the upper and lower in the actual use or working state of the device, specifically the drawing direction in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.
[0034] Please refer to Figure 1-2 , an embodiment of the present application provides a culture dish, including:
[0035] A culture dish body 2, in which a first light-shielding plate 22 is arranged. The first light-shielding plate 22 divides the culture dish body 2 into an adjacent first light-shielded part 23 and a first light-transmitting part 21. The height of the first light-shielding plate 22 is less than the height of the culture dish body 2;
[0036] A culture dish cover 1, in which a second light-shielding plate 12 is arranged. The second light-shielding plate 12 divides the culture dish cover 1 into an adjacent second light-shielded part 13 and a second light-transmitting part 11. The second light-shielded part 13 corresponds to the first light-shielded part 23, and the second light-transmitting part 11 corresponds to the first light-transmitting part 21. The second light-shielding plate 12 has a first end and a second end arranged oppositely, and gaps 14 are arranged between the first end and the second end and the adjacent culture dish cover 1 respectively.
[0037] It can be understood that after the culture dish body 2 is combined with the culture dish cover 1, the first light-shielding plate 22 corresponds to the second light-shielding plate 12, and a slit is formed between the first light-shielding plate 22 and the second light-shielding plate 12. At the same time, the first light-shielding plate 22 and the second light-shielding plate 12 jointly divide the culture dish chamber into a light-transmitting chamber and a light-shielding chamber. The light-transmitting chamber is composed of the first light-shielding plate 22, the second light-shielding plate 12, the first light-transmitting part 21 and the second light-transmitting part 11, and the light-shielding chamber is composed of the first light-shielding plate 22, the second light-shielding plate 12, the first light-blocking part 23 and the second light-blocking part 13. The light-transmitting chamber and the light-shielding chamber are communicated by a slit formed between the first light-shielding plate 22 and the second light-shielding plate 12. During use, a solid culture medium 3 is spread into the culture dish. Specifically, it is only necessary to make the surface of the solid culture medium 3 cover the surface of the first light-shielding plate 22, and after the culture dish body 2 is combined with the culture dish cover 1, the surface of the solid culture medium 3 does not touch the second light-shielding plate 12. When culturing plants vertically, plant seeds are sown on the solid culture medium 3 at the upper edge of the first light-shielding plate 22 on the side of the light-transmitting chamber. After the seeds germinate, the above-ground parts of the plants grow normally under light in the light-transmitting chamber, and the roots of the plants will grow downward along the surface of the solid culture medium 3 and enter the light-shielding chamber through the gap formed by the second light-shielding plate 12 and the solid culture medium, and grow in the dark state.
[0038] Compared with the traditional wrapping method and covering method, the operation process of the culture dish of the present application is simple, and it can better simulate the requirement of the plant roots to avoid light during natural growth, saving costs and greatly improving work efficiency.
[0039] In some embodiments, the materials of the first light-shielding plate 22, the second light-shielding plate 12, the first light-blocking part 23 and the second light-blocking part 13 independently include one or more of brown plastic, black plastic, brown glass and black glass.
[0040] In some embodiments, the materials of the first light-transmitting part 21 and the second light-transmitting part 11 independently include one or more of transparent plastic and transparent glass.
[0041] In some embodiments, the materials of the first light-shielding plate 22, the second light-shielding plate 12, the first light-blocking part 23 and the second light-blocking part 13 are the same as the materials of the first light-transmitting part 21 and the second light-transmitting part 11, and are all light-transmitting materials. Then, a light-blocking coating is coated on the surfaces of the materials of the first light-shielding plate 22, the second light-shielding plate 12, the first light-blocking part 23 and the second light-blocking part 13. The light-blocking coating is a conventional material in the art and can be obtained commercially.
[0042] Please refer to Figure 4, 9, and 10, in some embodiments, the height of the first light shield 22 is less than the height of the culture dish body 2. Thus, when adding the solid medium 3 into the culture dish body 2, it is convenient for the solid medium 3 to cover the upper part of the first light shield 22, so as to form a slit between the second light shield 12 and the solid medium 3, which is convenient for observing the growth of plant roots after planting plant seeds and placing them vertically.
[0043] Exemplarily, the height of the second light shield 12 is greater than the height of the culture dish cover 1. When adding the solid medium 3 into the culture dish body 2, the solid medium 3 covers the upper part of the first baffle. At the same time, when the culture dish cover 1 is covered with the culture dish body 2, a slit is formed between the second light shield 12 and the solid medium 3.
[0044] Also exemplarily, the height of the second light shield 12 is equal to the height of the culture dish cover 1. When adding the solid medium 3 into the culture dish body 2, the solid medium 3 covers the upper part of the first baffle. At the same time, when the culture dish cover 1 is covered with the culture dish body 2, a slit is formed between the second light shield 12 and the solid medium 3.
[0045] Furthermore exemplarily, the height of the second light shield 12 is less than the height of the culture dish cover 1. When adding the solid medium 3 into the culture dish body 2, the solid medium 3 covers the upper part of the first baffle. At the same time, when the culture dish cover 1 is covered with the culture dish body 2, a slit is formed between the second light shield 12 and the solid medium 3.
[0046] Please refer to Figure 1 , 3, 5, and 6, in some embodiments, there are notches 14 provided between the first end and the second end and their adjacent culture dish covers 1 respectively. It can be understood that due to the setting of the notches 14, when the culture dish cover 1 is covered with the culture dish body 2, the notches 14 coincide with the annular wall of the culture dish body 2 in contact with them, which is convenient for the culture dish cover 1 to be covered with the culture dish body 2.
[0047] Please refer to Figure 2 , 7, 8, 9, and 10, in some embodiments, the culture dish body 2 includes a bottom plate 25, the bottom plate 25 has a first surface, and a first annular wall 26 is provided along the outer periphery of the first surface. The first light shield 22 is located on the bottom plate 25 within the first annular wall 26.
[0048] Please refer to Figure 1 , 4, 6, 9, and 10, in some embodiments, the culture dish cover 1 includes a top plate 15, the top plate 15 has a second surface, and a second annular wall 16 is provided along the outer periphery of the second surface. The second light shield 12 is located on the top plate 15 within the second annular wall 16, and the notches 14 are provided between the first end and the second end and their adjacent second annular walls 16 respectively.
[0049] Please refer to Figure 3 Figures 5 and 6. In some embodiments, the width of the notch 14 is adapted to the width of the second annular wall 16. In this way, when the culture dish cover 1 is covered with the culture dish body 2, the notch 14 and the second annular wall 16 just fit together, and the gap between the two is minimized, resulting in a good light-blocking effect.
[0050] It can be understood that the first light-blocking plate 22 is located on the bottom plate 25 within the first annular wall 26, that is, the first light-blocking plate 22 is fixed to the bottom plate 25 within the first annular wall 26. The first light-blocking plate 22 has a third end and a fourth end arranged opposite to each other, and the third end and the fourth end are respectively in contact with the inner walls of the adjacent first annular wall 26.
[0051] Exemplarily, the first light-blocking plate 22 is located at the central axis position of the bottom plate 25. In this way, the first light-blocking plate 22 divides the culture dish body 2 into an equal-sized first light-shielding part 23 and a first light-transmitting part 21. At the same time, the second light-blocking plate 12 is located at the central axis position of the top plate 15. In this way, the second light-blocking plate 12 divides the culture dish cover 1 into an equal-sized second light-shielding part 13 and a second light-transmitting part 11. At this time, the sizes of the light-transmitting chamber and the light-blocking chamber are the same, which is used for cultivating plants with relatively short roots.
[0052] Also exemplarily, the first light-blocking plate 22 is located on one side away from the central axis of the bottom plate 25. In this way, the first light-blocking plate 22 divides the culture dish body 2 into a structure with one side larger and one side smaller. The larger side is the first light-shielding part 23, and the other side is the first light-transmitting part 21. At the same time, the second light-blocking plate 12 is located on one side away from the central axis of the bottom plate 25. In this way, the second light-blocking plate 12 divides the culture dish cover 1 into a structure with one side larger and one side smaller. The larger side is the second light-shielding part 13, and the other side is the second light-transmitting part 11. At this time, the light-transmitting chamber is smaller than the light-blocking chamber, which is used for cultivating plants with relatively long roots.
[0053] It can be understood that the central axis of the bottom plate 25 is parallel to the central axis of the bottom plate 25.
[0054] Please refer to Figure 2, 7 and 8, in some embodiments, light blocking strips 24 are respectively arranged at both ends of one side of the first light blocking plate 22 close to the first light shielding portion 23. Each light blocking strip 24 abuts against the adjacent first annular wall 26, and the height of each light blocking strip 24 is the same as the height of the first annular wall 26. It can be understood that the width of each light blocking strip 24 is greater than the width of the notch 14, so as to completely block the light between the notch 14 and the first annular wall 26. It can be understood that the height of each light blocking strip 24 is the same as the height of the first annular wall 26, which is convenient for the cover 1 of the culture dish to be covered with the main body 2 of the culture dish, and at the same time, the light blocking effect is good. The purpose of setting the light blocking strip 24 is to block the light coming through the gap between the notch 14 and the first annular wall 26, so as to further make the light shielding chamber in a dark state.
[0055] In some embodiments, the material of the light blocking strip 24 is one or more of brown plastic, black plastic, brown glass, and black glass.
[0056] In some embodiments, the material of the light blocking strip 24 is the same as that of the first light transmitting portion 21 and / or the second light transmitting portion 11, and then a light shielding coating is coated on the surface of the light blocking strip 24. The light shielding coating is a conventional material in the art and can be obtained commercially.
[0057] Please refer to Figure 9 and 10 , in some embodiments, the cross-section of the first light blocking plate 22 is smaller than the cross-section of the second light blocking plate 12. In this way, when culturing vertically and the cover 1 of the culture dish slides up and down, the width of the slit between the first light blocking plate 22 and the second light blocking plate 12 can be ensured to be sufficient.
[0058] In some embodiments, the thickness of the first light blocking plate 22 is 3 - 5 mm, for example, it can be 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, etc. Within this thickness range, it is beneficial to cooperate with the second light blocking plate 12 to form a slit, and when the cover 1 of the culture dish slides up and down, the width of the slit between the first light blocking plate 22 and the second light blocking plate 12 can be ensured to be sufficient.
[0059] In some embodiments, the thickness of the second light blocking plate 12 is 2 - 4 mm, for example, it can be 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, etc. Within this thickness range, it is beneficial to cooperate with the first light blocking plate 22 to form a slit, and when the cover 1 of the culture dish slides up and down, the width of the slit between the first light blocking plate 22 and the second light blocking plate 12 can be ensured to be sufficient.
[0060] Please refer to Figure 9 and 10, in some embodiments, when the culture dish cover 1 is configured to be closed with the culture dish body 2, the first light shielding plate 22 corresponds to the second light shielding plate 12, and a slit is formed between the first light shielding plate 22 and the second light shielding plate 12. During use, a solid culture medium 3 is laid in the culture dish. Specifically, it is only necessary to make the surface of the solid culture medium 3 cover the surface of the first light shielding plate 22, and after the culture dish body 2 and the culture dish cover 1 are combined, the surface of the solid culture medium 3 does not touch the second light shielding plate 12. When cultivating plants vertically, plant seeds are sown on the solid culture medium 3 at the upper edge of the first light shielding plate 22 on the side of the light-transmitting chamber. After the seeds germinate, the above-ground parts of the plants grow normally under light, and the roots of the plants will grow downward along the surface of the solid culture medium 3 and enter the light-shielding chamber through the gap formed by the second light shielding plate 12 and the solid culture medium, and grow in the dark state.
[0061] In some embodiments, the width of the slit is 1.5 - 4 mm, for example, it can be 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, etc. Within the width range of the slit, it is beneficial to observe the rooting situation of the seeds.
[0062] In some embodiments, the shape of the culture dish body 2 is circular or polygonal, and the shape of the culture dish cover 1 is the same as that of the corresponding culture dish body 2. In this way, the application range is wide.
[0063] The embodiments of the present invention have been introduced in detail above. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
