Abstract
The present invention provides a petri dish to solve the technical problems that the seal and ventilating state of a petri dish cannot be switched freely. The petri dish includes a dish plate and a dish cover capable of covering the dish plate; the dish plate is provided with a dish core internally; the sidewall of the dish plate is provided with a plurality of rows of inner through holes; the inner through holes in any row have the same spacing, and distance between centers of adjacent inner through holes is 2 times greater than the diameter; the outer diameter of the dish plate is corresponding to the inner diameter of the dish cover; the sidewall of the dish cover is provided with outer through holes in the same distribution as the inner through holes on the sidewall of the dish plate; and the upper surface of the dish cover is provided with a stop ring. the inner and outer through holes can be completely displaced by rotation of the dish cover or dish plate, or partially opposite, in order to achieve ventilation or sealing of the petri dish, as well as transition and transformation of ventilation and sealing. In addition, the outer through holes can serve as the point of strength for fingers to open the cover, so as to conveniently open the cover. The stop ring can enhance the stability for tacking the petri dishes.
Description
Technical field
The invention belongs to biological medicine experimental apparatus field, particularly relate to a kind of culture dish.
Background technology
Culture dish is used for cultivating microorganism (antibacterial and fungus) and cell (such as mammalian cell, cell tissue etc.) in the laboratory of biology or medical science.Different culture culture environment is different, and some needs to seal, and some needs ventilative, and it is ventilative that some needs sealing, some stage to need in some stage.Existing culture dish or be closed type, or vapor-permeable type, it is impossible to freely change sealing, under ventilative two states, it is difficult to adapt to the cultivation of some different culture, more cannot cultivate and need to realize sealing, breathing freely, in different phase, the culture changed.
Summary of the invention
The present invention solves that technical problem that the sealing of culture dish, ventilative state cannot freely change provides a kind of culture dish.
The technical solution used in the present invention is: a kind of culture dish, including ware dish and the ware lid that can cover on ware dish of culture dish；It is provided with ware core in described ware dish；On described ware dish sidewall, distribution straggly has some row's inner via holes, and the equal and adjacent inner via hole distance of center circle of inner via hole spacing in arbitrary row is more than 2 times of diameter；Described ware dish external diameter and described ware lid internal diameter are corresponding；Described ware lid sidewall is provided with and the accessibke porosity of inner via hole same distribution on ware dish sidewall；Described ware cap upper surface is provided with spacing ring.Rotate ware lid or ware dish, it is possible to inner via hole, accessibke porosity are staggered completely relatively or completely, it is also possible to part relatively, thus it is ventilative or seal to realize culture dish, and the ventilative and transition that seals and conversion.In addition, accessibke porosity be also used as open ware lid time finger impetus so that ware lid open more laborsaving.Spacing ring can improve stability when culture dish stacks.
As preferably, described ware lid inwall is provided with sealant；The through described sealant of described accessibke porosity.Sealant can reduce frictional force when coordinating pressure and rotation and opening and closing between ware dish, ware lid, and sealing effectiveness is more preferably.
As preferably, described spacing ring is uniformly divided into multistage, every one section vacant one section.So not only economize in raw materials, and reduce the frictional force of spacing ring and top ware dish when stacking, and finger can direct sending on earth, it is easier to inserting of top ware dish.
As preferably, described inner via hole and accessibke porosity are two rows.
The present invention has the advantage that and has the benefit effect that owing to the present invention adopts as above technical scheme, rotate ware lid or ware dish, can so that inner via hole, accessibke porosity stagger completely relatively or completely, can also partly relatively, thus it is ventilative or seal to realize culture dish, and the ventilative and transition that seals and conversion；Therefore both may be used for cultivating the culture needing to seal, it is also possible to cultivation needs ventilative culture, it is also possible to certain stage in growth course of cultivating needs the culture sealed, certain stage needs are ventilative, increases the culture dish scope of application；Additionally, accessibke porosity be also used as open ware lid time finger impetus so that ware lid open more laborsaving；Spacing ring can improve stability when culture dish stacks.

Detailed description of the invention
For the summary of the invention of the present invention, feature and effect can be further appreciated that, hereby enumerate following example, and it be as follows to coordinate accompanying drawing to describe in detail:
As shown in Figure 1, Figure 2 and Figure 3, the present embodiment is a kind of culture dish, including ware dish 1 and the Ke Gai ware lid 2 on ware dish 1 of culture dish；It is provided with ware core 3 in described ware dish 1；On described ware dish 1 sidewall, along the circumferential direction distribution has inner via hole 4, inner via hole 4 to be divided into two rows, and the equal and adjacent inner via hole distance of center circle of inner via hole 4 spacing in arbitrary row is more than 2 times of diameter；Stagger mutually in two row inner via hole 4 vertical direction positions；Described ware dish 1 external diameter and described ware lid 2 internal diameter are corresponding；Described ware lid 2 sidewall is provided with and the accessibke porosity 4 ' of inner via hole 4 same distribution on ware dish 1 sidewall；Namely can be completely superposed by rotation ware dish 1 or ware lid 2, inner via hole 4 and accessibke porosity 4 ' or stagger completely or half-open semi-closure；Described ware lid 2 inwall is provided with sealant 6；The through described sealant 6 of described accessibke porosity 4 '；Described ware lid 2 upper surface is provided with spacing ring 5；Described spacing ring 5 is uniformly divided into multistage, every one section vacant one section.
When the culture that cultivation needs are breathed freely or culture need the ventilative stage, inner via hole and accessibke porosity can be made to be completely superposed or partially overlap by rotation ware dish or ware lid, it is achieved breathing freely of culture dish；When cultivation needs the culture sealed or culture to need the stage sealed, by rotation ware dish or ware lid, inner via hole and accessibke porosity can be staggered completely, it is achieved the sealing of culture dish.
Above one embodiment of the present of invention is described in detail, but described content has been only presently preferred embodiments of the present invention, it is impossible to be considered the practical range for limiting the present invention.All equalizations made according to the present patent application scope change and improvement etc., all should still belong within the patent covering scope of the present invention.
