Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention relates to a culture container used for culturing plants and the like.

(Prior Art) In recent years, so-called culture in which microorganisms, plant tissue cells, etc. are divided and multiplied has been actively carried out, and in particular, cell culture called tissue culture is the cultivation of cell groups or tissue pieces. This culture requires a medium, and various containers are used to contain it. For example, it is common practice to use shears made of thick plastic material.

An agar medium is placed in the chalet main body, a tissue piece is placed in this medium, and after the chaire main body is covered with a lid, it is placed in a thermostatic chamber and cultured for a long period of time.

(Problem that the invention attempts to solve) It is necessary to regularly observe the growth status and occurrence of contamination of tissue fragments inside the shear, but in the above-mentioned shear, the tissue fragments are small. Due to the depth of the container, it was difficult to observe from the top of the shear dish, which required a long time to observe, resulting in problems such as delays in detecting abnormalities.

In view of this, the present invention has been designed to facilitate culture medium dispensing, planting tissue pieces, and transplanting to other containers, while also making it possible to clearly observe the interior from the top plate of the lid and to stack a large number of containers. The purpose of this invention is to provide a container to solve the conventional problems as described above.

[Structure of the idea]

(Means for Solving the Problems) The present invention for achieving the above object provides a culture container that has a container body and a lid that closes an upper opening of the container body. The main body is made of a permeable plastic material, and has a bottom and side walls for accommodating the culture medium, and is formed into a shallow container shape. The lid has a top plate and a side wall and is formed into a deep container shape, and a connecting portion that can be fitted into the main body connecting portion is provided at the lower end of the side wall, and the lid has a top plate and a side wall. The culture container is characterized in that a lens is formed on the plate, and the upper surface of the lens portion is recessed in a circular shape so that the bottom of the container body can be fitted into the culture container so that the culture container can be stacked.

(Function) With this structure, a culture medium can be housed in the container body, and tissue pieces of plants to be cultured can be easily placed therein, and transplantation is also easy, and light can be easily transmitted through the vertically long lid. This allows plant culture to be carried out without interfering with plant culture. Furthermore, by forming a lens on the top plate of the lid of the culture container, it is possible to magnify and observe the internal state.

(Example) The present invention will be described below with reference to the example shown in FIGS. 1 and 2.

The culture container 1 according to the present invention has a wall thickness of 1.5 m/m.
It consists of a transparent container body 2 and a lid 3 which are separately injection molded from a plastic material such as polycarbonate.

The container body 2 has a bottom portion 4 that protrudes downward in a circular manner.
and a shallow side wall 5 provided around it, a male thread-shaped part 6a is formed at the joint part 6 at the upper end of the side wall 5, and a side wall is formed between the side wall 5 and the joint part 6. A cylindrical side wall 7 having an outer diameter slightly larger than 5 is formed.

In the illustrated example, the lid 3 includes an octagonal top plate 9, eight vertically long side walls 8 that are inclined to open outward as they go downward from the top plate 9, and a side wall 8 that continues below the side wall 8. The inner diameter of the side wall 10 is slightly larger than the outer diameter of the side wall 5 of the container body 2. The container body 2 is provided inside the side wall 10.
A female threaded portion 11a is formed in the coupling portion 11 which is fitted into the male threaded portion 6a of the coupling portion 6.
Further, a recess 12 is formed in the top plate 9 to prevent bending, and a lens 13 is integrally formed in this recess. By fitting the bottom part 4, the lens 13 can be stacked even if there is a problem.

The lens 13 has a plano-convex lens structure with a flat surface on the outside and a convex lens on the inside. When the distance to the object to be observed is a, the distance to the image is b, and the focal length of the lens is f, a<f. It is desirable to obtain a virtual image, and the magnification factor X=b/a is in the range of 1.3<X<2.0.

Next, the operation of the above embodiment will be explained.

First, a culture medium 14 is placed in the container body 2, and a piece of tissue such as a plant is placed therein. When placed on the floor, since the container body 2 is shallow, the culture medium is located close to the upper end of the container body 2, making it easy to work and align the orientation.

Next, in order to fit the lid 3 onto the container body 2, the male threaded part 6a of the joint part 6 of the container body 2 and the female threaded part 11a of the joint part 11 of the lid 3 are screwed together. installation is completed.

The culture container 1 with the lid 3 connected in this way has excellent light transmittance, and since the joining part 11 between the lid 3 and the container body 2 is also located at a low position near the container body 2, direct light from above does not enter the culture container 1. There is no obstruction to the culture medium, and the entire surface of the container can be exposed to it, and the lens 13 provided on the top plate 9 of the lid 3 magnifies details such as the growth status of tissue pieces inside the culture container 1. and can be observed.

In this embodiment, a case has been described in which the container body 2 is circular and the lid is octagonal; however, these shapes and the structure of the joints 6 and 11 are not limited to the illustrated embodiment. do not have. Further, a ventilation hole may be provided in the top plate 9 of the lid 3, and the lens 13 may of course have a Fresnel lens structure. Furthermore, the lens 13 is not molded integrally with the lid 3, but is molded separately, and the concave portion 1 of the lid 3 is molded separately.
It may be attached to 2.

[Effect of idea]

As explained above, the culture container according to the present invention is
The container body and lid are made of a plastic material with good optical transparency, and the container body has a shallow bottom and the lid has a deep bottom, making it possible to connect both, making it easy to dispense the culture medium inside the container body and insert tissue pieces into the culture medium. Planting and transplanting to other containers can be easily done by removing the lid, and since the lid has excellent light transparency, direct light can be received over the entire surface of the container. In particular, the lens installed on the top plate of the lid makes it extremely easy to magnify and observe the details inside the culture container, making it possible to accurately grasp the growth status of tissue pieces and the occurrence of contamination. can do. In addition, even when the container body and lid are combined, the joint is close to the culture, so this joint does not block the incidence of light, and ventilation conditions are improved, resulting in faster absorption of CO ₂ . , it can also have excellent effects on plant growth.

Since the container is made of thin-walled plastic, it is lightweight, inexpensive, and disposable, so it can be cultured in a new, clean, and highly transparent state at any time.

Furthermore, even though there is a lens on the top plate of the lid, the containers have a stackable structure, so they can be stacked from any direction, and since they are non-directional containers, they can be used in future robots and automatic transplanting machines. It has many excellent effects, such as being compatible with automation of development etc.
