Description

Culture dish cover and culture dish Technical Field The utility model relates to the technical field of biomedical related equipment, in particular to a culture dish cover and a culture dish. Background A dish is a laboratory vessel for the cultivation of microorganisms or cells, consisting of a flat bottom and a lid, generally made of glass or plastic. When the culture dish is needed to be used, a culture medium and microorganisms or cells to be cultured are placed in the culture dish, then the placed microorganisms and cells are uniformly coated by a coating rod, and finally the culture work of various microorganisms and cells is completed. Wherein the application work of microorganisms or cells is performed by laboratory staff through the existing application bar, i.e., the laboratory staff takes the application bar and then uniformly applies the bacterial-containing culture solution to the entire upper surface of the culture medium with the application bar, the coating process has poor coating effect and low efficiency, and the cover is opened for a long time in the coating process, so that the risk of exogenous pollution is increased. Disclosure of utility model The utility model aims to solve at least one of the technical problems in the related art to a certain extent, and provides a culture dish cover and a culture dish, which have good coating effect and simple and efficient operation, and particularly, the cover and the bottom are in a cover-closed state in the coating process, so that the risk of exogenous pollution is reduced. Therefore, one object of the present utility model is to provide a culture dish cover, which comprises a cover body, wherein the outer edge of the cover body is provided with a downward flanging, a containing cavity is formed in the cover body, a plurality of balls are arranged in the containing cavity, a ball passing hole communicated with the containing cavity is formed in the lower end face of the cover body, and the diameter of the ball passing hole is matched with the diameter of the ball, so that the ball can pass through the ball passing hole. The ball in the lid can make the ball fall into in the culture dish when the lid closes on current culture dish drain pan, accomplishes the coating to the microorganism in the culture dish along with the rocking of culture dish, after the culture dish is invertd at last, the ball can get back to through ball hole and hold the intracavity for the ball is adorned behind the coating with the microorganism separation on culture medium and the culture medium, reduces the influence to the microorganism on the culture medium in the follow-up culture process. Preferably, the cover body is provided with a protective patch for covering the ball through hole, and the protective patch is attached to the cover body in a tearing manner. The ball through hole can be sealed through the protective paster, and the protective paster is torn when the cover body is required to be used, so that the cover body can be used for covering the bottom shell of the culture dish. Preferably, the ball through hole is communicated with the outer edge position of the accommodating cavity. Preferably, the center of the bottom surface of the accommodating cavity is provided with a convex guiding inclined surface for driving the balls to move along the horizontal direction in a direction away from the center line of the accommodating cavity. The ball in the accommodating cavity can move to the position abutting against the side wall of the accommodating cavity along the radial direction under the condition that the cover body is horizontally placed through the guide inclined surface, and the ball can sequentially drop into the culture dish below from the ball passing hole along with the shaking of the cover body. Preferably, the cover body is arranged on the lower end face corresponding to the accommodating cavity in an inclined mode, and the through hole is positioned at a position, along the vertical direction, of the lower end face. The lower terminal surface that the slope set up not only can make the ball that holds the intracavity fall into the culture dish of below through ball hole in proper order under self action of gravity before the coating, and the ball also can roll towards ball hole place through the lower terminal surface of this slope when finishing the coating back to invert the culture dish moreover, finally fall back to holding the intracavity. Preferably, the cover body comprises an upper cover and a lower cover, the upper cover and the lower cover are detachably connected, the upper cover and the lower cover surround to form a containing cavity, and the through ball hole is positioned on the lower cover. The cover body consists of a detachable upper cover and a detachable lower cover, so that the cover body and the balls in the cover body are cleaned and disinfected after the cover body is conveniently detached.
