However, since these culture vessels have poor air permeability, they can be used by loosening the screw caps, cotton plugs, paper stoppers, etc. in order to supply oxygen and carbon dioxide required for respiration and photosynthesis of the cultures. Although gas is exchanged using aluminum foil, etc., it is often the case that sufficient ventilation cannot be ensured. Further, in order to ensure air permeability, it is necessary to always loosen the plugs of the above-mentioned opening, so that the dissipation of the medium becomes large, and therefore the concentration of the medium is increased, which inhibits the growth of the culture, and is always a bacteria. There are problems such as being exposed to the risk of intrusion. In addition, these culture vessels have narrow openings, making it very difficult to manipulate the culture, and the operation of loading and unloading the culture requires a lot of experience and time, and sometimes the culture is damaged and damaged. The reality is that there are many problems, such as a decrease in the rate.

Therefore, while maintaining various properties such as light transmittance and durability, it has sufficient air permeability for growing a culture without invasion of various bacteria, has a small loss of medium, and is easy to operate. There is a need for good culture vessels. In order to achieve the above object, a culture container in which a fluorine-containing molten resin film having high gas permeability is processed into a bag shape has been proposed (see JP-A-63-198972). However, for some culture targets or culture conditions, higher gas permeability is required, and since the melting temperature of fluororesin is as high as about 300 ° C, the heat bonding operation during film processing is not easy. It became clear. Further, the fluororesin is not practical because it is relatively expensive and inferior in operability.

Japanese Unexamined Patent Publication (Kokai) No. 3-277268 discloses a cell culture bag using a film made of a polymer alloy of low density polyethylene and linear low density polyethylene, but low density polyethylene also has sufficient gas permeability. However, there is a problem that the bag-like form is inferior in operability. Furthermore, in recent years, porous membranes have begun to be used in some culture vessels, but the material of these porous membranes is generally a substance having a high light transmittance, but diffused reflection of light rays occurs due to porosity, Therefore, there was great resistance to use such an opaque material in a culture container where photosynthesis is important.

Further, since many culture vessels need to be sterilized before use, the porous membrane material that can withstand this treatment temperature is limited, and it is inevitable for culture vessels that require high air permeability. There is no choice but to use a large area porous membrane
Therefore, there has been a limit to the use of a porous film that shields light rays. In addition, as a method of using the porous membrane, since a method of applying an adhesive to the porous membrane and attaching it to the culture container has been taken, there is a problem that the replacement of the porous membrane cannot be easily performed, and thus it is practical. is not.

As shown in the table, the culture container of the present invention has a very good growth condition of the cultured seedlings, has a wider opening than the conventional culture container, and can be easily sealed. No special experience is required for planting or removing, and it can be done easily in a short time without being contaminated by various bacteria. Furthermore, by using a light-permeable container and a porous membrane with high gas permeability, it is possible to keep the gas, water, and light environment inside the culture container optimal, and create an optimal growth environment for the contents. Workability has also been improved by adopting a structure that allows easy replacement of the membrane. Since the container can be manufactured by the conventional general-purpose manufacturing method, an inexpensive and practical culture container can be provided.
