大変であり、労力も必要だし時間もかかるものである。However, in the course of culturing, it is necessary to observe the state of culture, such as the observation of colonies. The observation is open to the public, but this is not easy only for microbes. Therefore, the lid 103 is actually opened and observation is performed using a magnifying lens (magnifying glass) or the like. However, the cultivation of specimens such as bacteria
It is not performed in one petri dish, but is performed using a plurality of petri dishes even for one subject. When the number of subjects is several, the number becomes extremely large. For example, when the same subject is to be cultured simultaneously in a plurality of different types of culture media, a plurality of Petri dishes into which each of those culture media is injected are required. Even when culturing a specimen, a petri dish into which a medium corresponding to the number of the specimen is injected is required. It is difficult to observe a large number of petri dishes with a magnifying glass by opening the lid each time, which requires labor and time.

のものでよい。In FIG. 1, a petri dish 1 includes a main body 2,
The main body 2 is composed of a bottom plate 4 and a side wall 5 in a circular dish shape, and the lid body 3 is a top plate 6.
Into a shape that can be fitted to the main body 2 with the side wall 7 and
Each is made of synthetic resin or glass. The shape of the petri dish 1 is not limited to the illustrated embodiment, and may be a conventionally known one.

の全体がフレネルレンズ８に形成されてもよい。A Fresnel lens 8 is formed on a part of the top plate 6 of the lid 3. As shown in FIG. 2, the Fresnel lens 8 is formed by forming a plurality of grooves 8a in a concentric orbicular shape on the inner surface of the top plate 6. Accordingly, the Fresnel lens 8 can be formed at the same time by forming a shape corresponding to the mold and integrally molding the lid 3 with a transparent synthetic resin or glass. In this example, the Fresnel lens 8 is formed at the center of the top plate 6, but the present invention is not limited to this, and the position and size can be freely selected. Further, the Fresnel lens 8 is not a part of the top plate 6 but the top plate 6.
May be formed in the Fresnel lens 8.

The culture state of the culture medium is such that the lid 3 is fitted to the main body 2,
The image can be enlarged and observed through the Fresnel lens 8.

易であるし、安価に提供できる。As described above in detail, according to the present invention, since the top plate of the lid is entirely or partially formed in the Fresnel lens, the lid is opened one by one or another magnifying glass is used. Without leaving the lid fitted to the main body,
Observation of the culture state in the petri dish can be easily performed through the Fresnel lens. Since the lid is not opened and another magnifying glass is not used, no labor or effort is required and the system is efficient. In addition, since it is a Fresnel lens, it can be integrally molded at the time of molding the lid, and is extremely easy to manufacture and can be provided at low cost.
