Description

Technical Field

[0001] The utility model relates to the technical field of culture dishes, in particular to a microbial culture dish. Background Art

[0002] Microbial culture dishes are indispensable tools in biological experiments. Their main function is to provide a sterile and suitable environment for the separation, purification and cultivation of microorganisms. By inoculating the sample to be tested on the culture medium in the culture dish, the growth of microorganisms can be observed, including characteristics such as colony morphology, color, and growth rate, so as to identify, count, or study the physiological and biochemical characteristics of microorganisms. Culture dishes mainly include glass and plastic (such as polystyrene, polypropylene, cellulose acetate or polyethylene). Glass culture dishes are usually used in situations that require higher heat resistance and chemical stability, while plastic culture dishes are popular because of their lightness, unbreakableness and low cost.

[0003] During the actual use of the culture dish, it is necessary to prevent the bottom and cover of the culture dish from accidentally detaching. In the prior art, as disclosed in Chinese utility model patent CN202023077158.9, an anti-falling microbial culture dish is magnetically attracted to the cover and the bottom of the dish; as disclosed in Chinese utility model patent CN202021020521.0, a new type of microbial culture dish is designed with a connector between the bottom and the cover of the culture dish so that the connecting ends of the two are always in a closed state.

[0004] During the actual use of the culture dishes, they also need to be stacked to cope with the situation of being placed in a small space (such as placing them in a transfer box or a constant temperature box). This situation generally requires the use of a culture dish rack or a transfer rack, such as a microbial culture dish rack disclosed in Chinese utility model patent CN202023122234.3, or a stackable microbial culture dish disclosed in Chinese utility model patent CN202320750918.2.

[0005] However, none of the above-mentioned public documents has a structure that can prevent the bottom and cover of the culture dish from accidentally separating and can stably stack the culture dishes, which causes many inconveniences in the actual use of the culture dishes.

Specific embodiments

[0028] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments may be combined with each other.

[0029] As Figures 1 to 8 shown in the embodiment of the microbial culture dish of the present utility model, the microbial culture dish includes a dish bottom 1, a dish lid 2, a bottom plug 3 and a lid plug 4 that are all annular. The dish bottom 1, the dish lid 2, the bottom plug 3 and the lid plug 4 are all provided with a central through hole. A bottom plug 3 is fixedly provided in the central through hole of the dish bottom 1, and a lid plug 4 is fixedly provided in the central through hole of the dish lid. The upper end of the bottom plug 3 is threadedly connected to the lower end of the lid plug 4. The upper end of the lid plug 4 can be embedded in the lower end of the bottom plug 3. The upper end of the lid plug 4 protrudes from the upper surface of the dish lid 2. The central through holes of the bottom plug 3 and the lid plug 4 are used to pass through the support rod 5 for stacking.

[0030] Since the dish bottom 1 and the bottom plug 3 are fixedly connected, and the dish lid 2 and the plug lid 4 are fixedly connected, after the bottom plug 3 and the lid plug 4 are threadedly connected, the dish bottom 1 and the dish lid 2 can be fixedly connected to prevent them from separating due to accidents.

[0031] Since the upper end of the plug 4 can be inserted into the lower end of the bottom plug 3, and the upper end of the plug 4 protrudes from the upper surface of the dish cover 2, when it is necessary to stack multiple culture dishes in this factual example, the plug 4 of the lower culture dish can be inserted into the bottom plug 3 of the upper culture dish, so that the upper and lower culture dishes can be stably stacked together to prevent accidental collapse.

[0032] Since the central through holes of the bottom plug 3 and the plug 4 can pass through the support rod 5, multiple culture dishes can be passed through the central through holes of the bottom plug 3 and the plug 4 onto the support rod 5, making the stacking of multiple culture dishes more stable; specifically, the support rod 5 can be a round rod, and a base 51 is fixedly provided at the bottom end of the support rod 5.

[0033] In this factual example, since the upper end of the plug 4 can be inserted into the lower end of the bottom plug 3, and the upper end of the bottom plug 3 is threadedly connected to the lower end of the plug 4, the support rod 5 only contacts the central through hole of the plug 4; this can also prevent the support rod 5 from bending due to external force extrusion on the support rod 5, or when an external force extrudes the culture dish, the external force is preferentially applied to the dish cover 2 to avoid further affecting the dish bottom 1 (the culture substance is in the dish bottom 1).

[0034] In this way, the microbial culture dish of the present utility model can not only achieve a stable fixed connection between the dish bottom 1 and the dish cover 2, prevent the dish bottom and the dish cover from accidentally separating, but also multiple culture dishes can be stably stacked to prevent accidental collapse during stacking.

[0035] In an embodiment of the present application, preferably, both the dish bottom 1 and the dish cover 2 include an outer peripheral wall and an inner peripheral wall. The outer peripheral wall of the dish cover 2 is outside the outer peripheral wall of the dish bottom 1, and the inner peripheral wall of the dish cover 2 is inside the inner peripheral wall of the dish bottom 1; in this way, the culture substance in the culture dish can be cultured only in the dish bottom 1, and the outer peripheral wall and the inner peripheral wall of the dish bottom 1 play an isolation role, so that the culture substance generally does not contact the dish cover 2.

[0036] In an embodiment of the present application, preferably, two sealing rings 21 are fixedly provided in the dish cover 2, and the two sealing rings 21 respectively abut against the top of the outer peripheral wall and the top of the inner peripheral wall of the dish bottom 1; in this way, when it is necessary to perform sealed culture, only the bottom plug 3 and the plug 4 need to be tightened threadedly to obtain a relatively sealed culture environment, without the need to use sealing means such as a sealing film, paraffin film or plastic wrap. The sealing process is simple and easy to operate and can ensure the sealing effect, preventing unsealing caused by improper operation.

[0037] In an embodiment of the present application, preferably, as Figure 8 shown, fixing blocks 22 for embedding the sealing rings 21 are provided on the inner wall of the dish cover 2.

[0038] If sealed culture is not required, the sealing rings can be removed, and a gap is provided between the outer peripheral wall and the inner peripheral wall of the dish cover 2 and the dish bottom 1, and this gap still exists when the bottom plug 3 and the plug 4 are tightened threadedly.

[0039] In an embodiment of the present application, preferably, the outer peripheral wall of the dish cover 2 inclines outward, and the inner peripheral wall of the dish cover 2 inclines inward, so as to facilitate covering the dish cover 2 onto the dish bottom 1.

[0040] In an embodiment of the present application, preferably, a radial partition wall 11 is provided between the outer peripheral wall and the inner peripheral wall of the dish bottom 1, so that separated culture can be carried out within the dish bottom 1; when sealed separated culture needs to be carried out within the dish bottom 1, the sealing ring 21 can be modified, and a sealing piece at the top end of the partition wall 11 can be added to complete the sealed separated culture.

[0041] In an embodiment of the present application, preferably, an axial rib c is provided in the central through hole of the dish bottom 1 and the dish cover 2, and rib grooves d are correspondingly provided on the outer walls of the bottom plug 3 and the cover plug 4, and the axial rib c and the rib grooves d cooperate to prevent circumferential offset.

[0042] In an embodiment of the present application, preferably, the dish bottom 1 and the bottom plug 3 are fixedly connected by interference fit and / or glue bonding, and the dish cover 2 and the cover plug 4 are fixedly connected by interference fit and / or glue bonding.

[0043] In an embodiment of the present application, preferably, a stacking ring 41 is fixedly provided between the upper end and the lower end of the cover plug 4, and the bottom surface of the stacking ring 41 is fixedly connected to the dish cover 2; the stacking ring 41 creates a gap between the stacked culture dishes, preventing adjacent culture dishes from knocking against each other.

[0044] In an embodiment of the present application, preferably, a base 51 is fixedly provided at the bottom end of the support rod 5, and an anti-collision ring 52 is further provided on the base 51 at the bottom end of the support rod 5. The anti-collision ring 52 has a similar function to the stacking ring 41, playing a role in preventing knocking between the culture dish and the base 51.

[0045] In an embodiment of the present application, preferably, axial anti-slip ribs 42 arranged at equal intervals in the circumferential direction of the outer wall are provided on the outer wall of the upper end of the cover plug 4; when a staff member holds the upper end of the cover plug 4 and picks up the dish cover 2 or unscrews / tightens the dish cover 2, the anti-slip ribs 42 play an anti-slip effect, making it easier for the staff member to pick up the dish cover 2 or unscrew / tighten the dish cover 2.

[0046] In an embodiment of the present application, preferably, axial grooves 31 arranged at equal intervals in the circumferential direction of the inner wall are provided on the inner wall of the lower end of the bottom plug 3, and the anti-slip ribs 42 can be embedded into the axial grooves 31 to prevent rotation between two culture dishes when the culture dishes are stacked.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
