[0002] Culture dishes are laboratory vessels, mainly made of glass and plastic, usually used for culturing microorganisms or cells, wherein the glass culture dishes are reusable, and the plastic culture dishes are mostly disposable. Culture dishes are generally composed of a disc-shaped bottom and a cover, and are one of the most common experimental apparatus in biochemical laboratories.
[0003] The current culture dishes have structural deficiencies, for example: when picking up the culture dishes, the bottom and the cover are not closed by friction, causing the culture dish bottom to slide off during the process of picking up the culture dish; or when stacking multiple culture dishes, they are unstable and easy to tip over and break; furthermore, some culture dishes do not have counting grids, which is not convenient for colony counting in different places, that is, it is not convenient to count the number of colonies of the collected or detected objects, and thus it is not suitable for colony culture experiments that require counting in different areas.
[0004] To solve the problem of colony counting, the existing patent CN206956033U discloses a hand sampling plate culture dish to meet the demand of hand contact sampling. The grid strip includes first and second grid strips perpendicular to each other, and any two first and second grid strips are perpendicular to each other to form a grid, which is convenient for colony counting, but multiple hand sampling plate culture dishes are still unstable when stacked, thus there is a possibility of tipping over.

DETAILED DESCRIPTION

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used in the description of the disclosure herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.
[0034] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below in combination with specific embodiments:
[0035] Please refer to Figure 1 , which is a microorganism culture dish 10 for easy use according to an embodiment of the present disclosure, comprising an upper cover 100 and a culture bottom plate 200.
[0036] As shown in Figures 3 to 6 , the culture bottom plate 200 comprises a culture plate 210 and a bottom plate body 220 connected together, the culture plate 210 is provided with a plurality of division strips 211 and counting cells 212, each counting cell 212 is arranged between the plurality of division strips 211, the outer side of the upper cover 100 is provided with a first anti-skid pattern 101, and the outer side of the bottom plate body 220 is provided with a second anti-skid pattern 220a; in combination with Figure 2As shown, the inner side of the upper cover 100 has a frosted area 102, the outer periphery of the culture substrate 210 is provided with an outer periphery protruding ring 2101, and the outer side of the outer periphery protruding ring 2101 has a third anti-skid pattern 2101a. When the upper cover 100 is combined with the culture base plate 200, the frosted area 102 corresponds to the third anti-skid pattern 2101a. Figure 3 and Figure 5 As shown, one side of the culture substrate 210 has an arc-shaped area 210a, the counting grid 212 and the division strip 211 are located in the arc-shaped area 210a, and the base plate body 220 is provided with a limiting groove 221. The opening direction of the limiting groove 221 is away from the culture substrate 210, and the limiting groove 221 is used for corresponding to the upper cover 100 of another microbial culture dish 10 during stacking operation.
[0037] In this embodiment, the inner side of the upper cover 100 of the microbial culture dish 10 has a frosted area 102, and the outer side of the outer periphery protruding ring 2101 has a third anti-skid pattern 2101a. The frosted area 102 and the third anti-skid pattern 2101a are arranged so that when the upper cover 100 is combined with the culture base plate 200, the upper cover 100 is less likely to be separated from the culture base plate 200 when a person holds the microbial culture dish 10; the limiting groove 221 can be used for stacking multiple microbial culture dishes 10 through the limiting groove 221. When multiple microbial culture dishes 10 are used, each upper cover 100 is affected by the corresponding limiting groove 221, and the multiple microbial culture dishes 10 are less likely to be tilted; the culture substrate 210 is provided with the division strip 211 and the counting grid 212 to facilitate colony counting. In addition, one side of the culture substrate 210 has an arc-shaped area 210a, so that the culture forms an arc when it is on the culture substrate 210, which facilitates sampling of the colonies. In summary, the microbial culture dish 10 of the present scheme has high convenience of use.
[0038] It can be understood that the inner side of the upper cover 100 has a frosted area 102, which can increase the friction between the inner side of the upper cover 100 and the outer side of the outer periphery protruding ring 2101 when the upper cover 100 is combined with the culture base plate 200, which makes it difficult for a person to hold the microbial culture dish 10 and cause the culture base plate 200 to fall off. In addition, one side of the culture substrate 210 has an arc-shaped area 210a, and the culture generally adheres to the edge of the counting grid 212, so that the culture forms an arc when it is on the culture substrate 210, that is, the amount of culture on the edge part of the culture substrate 210 is more, and the amount of culture on the center part of the culture substrate 210 is less, thereby facilitating sampling operation of the microorganisms.
[0039] In another embodiment, the maximum thickness of the arc-shaped area 210a is 1.5 mm.
[0040] As Figure 4 and Figure 5As shown, in one embodiment, the cross-sectional area of the base plate body 220 gradually increases in the direction away from the culture medium plate 210. This makes the bottom of the base plate body 220 have a larger projected area on the plane, so that the microbial culture dish 10 can be placed more stably on the plane (such as a laboratory table, incubator, etc.), and prevents the microbial culture dish 10 from tilting due to the bottom of the base plate body 220 having too small a projected area on the plane.
[0041] In one embodiment, the cross-sectional diameter of the culture medium plate 210 is 60 ± 5 mm. In this embodiment, the cross-sectional diameter of the culture medium plate 210 is 55 mm.
[0042] In one embodiment, the cross-sectional diameter of the bottom of the limiting groove 221 is 63±3mm. In this embodiment, the cross-sectional diameter of the bottom of the limiting groove 221 is 60mm.
[0043] like Figure 6 As shown, in one embodiment, the dividing strip 211 includes a plurality of horizontal dividing strips 2111 and a plurality of vertical dividing strips 2112. The extension line of any horizontal dividing strip 2111 is perpendicular to the extension line of any vertical dividing strip 2112. Both the horizontal dividing strips 2111 and the vertical dividing strips 2112 are located within the arc-shaped area 210a. The horizontal dividing strips 2111 are connected to the horizontal line of the counting grid 212, and the vertical dividing strips 2112 are connected to the vertical line of the counting grid 212. It can be understood that any horizontal dividing strip 2111 is perpendicular to any vertical dividing strip 2112. When the extension lines of multiple horizontal dividing strips 2111 are perpendicular to the extension lines of vertical dividing strips 2112, a grid is formed. Specifically, when any two adjacent horizontal dividing strips 2111 and any two adjacent vertical dividing strips 2112 are perpendicular, a counting grid 212 can be formed. Thus, the culture medium plate 210 has multiple counting grids 212, making it convenient for operators to sample the culture medium located in the counting grid 212.
[0044] like Figure 6 As shown, in one embodiment, multiple horizontal dividing strips 2111 are equidistantly arranged. It can be understood that when multiple horizontal dividing strips 2111 are equidistantly arranged, such that when any two adjacent horizontal dividing strips 2111 and any two adjacent vertical dividing strips 2112 perpendicularly form a counting cell 212, the length of the counting cell 212 in the vertical direction is equal. This provides better visibility for operators conducting microbial culture experiments, meaning they can visually observe that the vertical lengths of the multiple counting cells 212 are consistent.
[0045] like Figure 6As shown, in one of the embodiments, the plurality of vertical division bars 2112 are equidistantly arranged. It can be understood that when the plurality of vertical division bars 2112 are equidistantly arranged, in the case that the counting grids 212 are vertically formed by any two adjacent horizontal division bars 2111 and any two adjacent vertical division bars 2112, the length of the counting grids 212 in the horizontal direction is equal, which makes it easier for the operator to visually observe the uniform length of the plurality of counting grids 212 in the horizontal direction, thereby achieving the effect that the experimental conditions of the various colonies in different counting grids 212 are consistent.
[0046] As shown in FIG. 1, the plurality of horizontal division bars 2111 and the plurality of vertical division bars 2112 are arranged on the culture plate 210, and the plurality of horizontal division bars 2111 and the plurality of vertical division bars 2112 are arranged in a grid manner. Figure 6 As shown, in one of the embodiments, the ratio of the distance D1 formed by two adjacent horizontal division bars 2111 to the distance D2 formed by two adjacent vertical division bars 2112 is 1:1, i.e. D1:D2 = 1:1. It can be understood that when any two adjacent horizontal division bars 2111 and any two adjacent vertical division bars 2112 are perpendicular and the distance ratio is 1:1, the extension lines of the two adjacent horizontal division bars 2111 and the extension lines of the two adjacent vertical division bars 2112 form a square-shaped counting grid 212. In this way, the microbial culture dish 10 has a plurality of square-shaped counting grids 212, which optimizes the arrangement of the counting grids 212 and enables the culture plate 210 to have more square-shaped counting grids 212 in a limited space, thereby facilitating the consistency and repeatability of the experimental conditions.
[0047] In one of the embodiments, the number ratio of the horizontal division bars 2111 to the vertical division bars 2112 is 1:1. In this embodiment, in the case that the plurality of horizontal division bars 2111 are equidistantly arranged and the plurality of vertical division bars 2112 are equidistantly arranged, a plurality of square-shaped counting grids 212 can be formed. When the number ratio of the horizontal division bars 2111 to the vertical division bars 2112 is 1:1, i.e. the number of the horizontal division bars 2111 is equal to the number of the vertical division bars 2112, the plurality of square-shaped counting grids 212 can form a square-shaped counting grid 212 as a whole, thereby facilitating the identification and experimental operation of the operator.
[0048] As shown in FIG. 1, the plurality of horizontal division bars 2111 and the plurality of vertical division bars 2112 are arranged on the culture plate 210, and the plurality of horizontal division bars 2111 and the plurality of vertical division bars 2112 are arranged in a grid manner. Figure 5 As shown in FIG. 1, the plurality of horizontal division bars 2111 and the plurality of vertical division bars 2112 are arranged on the culture plate 210, and the plurality of horizontal division bars 2111 and the plurality of vertical division bars 2112 are arranged in a grid manner. Figure 7 As shown, in one of the embodiments, the groove bottom of the limiting groove 221 has an anti-slip rough area 2211. It can be understood that when the groove bottom of the limiting groove 221 has the anti-slip rough area 2211, since the groove bottom is used to abut against the upper cover 100 of another microbial culture dish 10 during stacking operation, and the groove bottom has the anti-slip rough area 2211, which is a rough surface, this increases the friction between the limiting groove 221 and the upper cover 100, and it is less likely that the culture bottom plate 200 and / or the upper cover 100 will be positionally deviated to cause tilting. Figure 7The bottom surface of the bottom plate 200 is formed with a roughened area 2211, which is located at the bottom of the limiting groove 221.
[0049] In one embodiment, the height of the peripheral protruding ring 2101 is 4-6mm. In this embodiment, the height of the peripheral protruding ring 2101 is 4mm.
[0050] In one embodiment, the height of the bottom plate body 220 is 4-6mm. In this embodiment, the height of the bottom plate body 220 is 4mm.
[0051] Compared with the prior art, the present disclosure has at least the following advantages:
[0052] The microorganism culture dish 10 described above has the following advantages: the inner side of the upper cover 100 is provided with a frosted area 102, and the outer side of the peripheral protruding ring 2101 is provided with a third anti-skid pattern 2101a, so that when the microorganism culture dish 10 is held by a human hand, the upper cover 100 is less likely to be separated from the culture bottom plate 200; the limiting groove 221 is provided, so that a plurality of microorganism culture dishes 10 can be stacked through the limiting groove 221, and when the plurality of microorganism culture dishes 10 are stacked, each upper cover 100 is affected by the corresponding limiting groove 221, so that the plurality of microorganism culture dishes 10 are less likely to be tilted; the culture substrate 210 is provided with a partition strip 211 and a counting grid 212, so as to facilitate colony counting; in addition, one side of the culture substrate 210 is provided with an arc-shaped area 210a, so that the culture substrate 210 forms an arc shape when the culture substrate 210 is used, which facilitates colony sampling; in summary, the microorganism culture dish 10 of the present scheme has high convenience in use.
[0053] The above-described embodiments only express several embodiments of the present disclosure, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the disclosed patent. It should be noted that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure.
