Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a culture vessel used for culturing an object to be cultivated, such as mushrooms such as enokitake mushrooms and shimeji mushrooms, or tissues of orchids and lilies.

[0002]

2. Description of the Related Art In general, so-called bottle culture using a wide-mouthed bottle-shaped culture container is generally used for cultivating mushrooms (objects to be cultured) such as enoki mushrooms and shimeji mushrooms. Hereinafter, the procedure of the bottle culture will be described.

That is, a medium containing water by mixing sawdust, bran and the like is filled in the culture container, and the culture container is sterilized by heating and then left to cool in a sterile room. afterwards,
The medium in the culture vessel is inoculated with the inoculum of mushrooms in a sterile room. Then, the culture container after the inoculation is carried to the culture chamber, so that the hyphae in the culture container grow in the culture chamber.

By the way, when the culture medium in the culture container is dried, the growth of the mycelium of the fungi is inhibited, so that the opening of the culture container is closed with a lid, but the opening of the culture container is completely closed. If it is hermetically sealed, the oxygen necessary for the growth of the mycelia will not be sufficiently supplied into the culture container.

For this reason, the lid is provided with a ventilation hole so that the inside of the culture vessel can be ventilated. However, when various bacteria enter the culture vessel through the ventilation hole, the medium in the culture vessel and Mycelia of mushrooms rot. Conventionally, as a measure against this, for example, as shown in FIG. 11, a culture container is provided from a vent hole (31) through a filter (32) made of sponge or the like.
(6) The outside air is vented into the inside.

By the way, in order to reduce the drying of the culture medium in the culture vessel (6), it is preferable to make the vent hole (31) as small as possible. However, if the ventilation hole (31) is made too small, the amount of ventilation into the culture container (6) is reduced, and the growth of the hyphae of mushrooms is inhibited.

[0007]

Therefore, the vent hole (3
The size of 1) will be determined according to the oxygen consumption of fungi of mushrooms in the culture vessel (6), and the oxygen consumption is the kind of mushroom or culture in the culture vessel (6). Depends on temperature. In order to deal with this, conventionally, a lid is prepared according to the type of mushroom and the culture temperature, and the lid is replaced according to the type of mushroom to be cultured and the culture temperature. As a result, it took a lot of time to manage the lid.

Moreover, the culture temperature may be adjusted while confirming the growth of mycelia. For example, when the culture temperature is raised, the oxygen consumption of the bacteria also increases accordingly. However, since the size of the conventional vent hole (31) is fixed, when the culture temperature is raised, the amount of aeration into the culture container (6) becomes insufficient and mycelia grow sufficiently. Can not. INDUSTRIAL APPLICABILITY The present invention makes it possible to adjust the amount of aeration into the culture container, reduce the labor of managing the lid, and to sufficiently grow the culture target to enhance the productivity of the culture of the culture target. The purpose is to

[0009]

In order to achieve the above object, the present invention is configured as follows, as shown in FIGS. 1 to 5, for example. With the lid (1) removably fitted in the opening (7) of the culture vessel (6), the filter (4) provided on the lid (1) through the ventilation hole (10) formed in the lid (1). In the culture container configured to ventilate the outside air into the culture container (6) via the (1), the culture container from the ventilation hole (10) of the lid (1).
(6) The lid (1) is provided with ventilation control means capable of controlling the amount of ventilation to the inside.

[0010]

The present invention operates as follows, for example, as shown in FIGS. Open the lid (1) with the opening (7) of the culture vessel (6)
Air is filtered through the ventilation hole (10) when
The culture container (6) is ventilated through (4). As a result, the inside of the culture vessel (6) is ventilated. On the other hand, the aeration amount is adjusted by the aeration control means according to the kind of the culture object such as mushrooms to be cultured in the culture container (6) and the culture temperature.

[0011]

The present invention has the following effects because it is configured and operates as described above. Since the aeration amount into the culture container is configured to be adjustable by the aeration adjusting means, the aeration amount can be set according to the kind of the mushroom or the like to be cultured (culture target) and the culture temperature. In other words, one lid can handle the type of the culture object and the culture temperature, and it is not necessary to prepare the lid for the amount corresponding to the type of the culture object and the culture temperature as in the conventional case. Therefore, it is possible to reduce the labor of managing the lid, to make it possible to appropriately grow the amount of aeration in the culture container to sufficiently grow the culture target, and to obtain a good quality culture target and to culture the culture target. Productivity can be increased.

According to a second aspect of the present invention, a lid is formed by using two upper and lower lids that are fitted to each other, and the upper lid is rotatable in the circumferential direction of the lower lid. If the upper lid is provided with a ventilation hole and the ventilation hole faces the opening of the lower lid so as to ventilate into the culture vessel, the lid is fitted into the opening of the culture vessel. The amount of aeration into the culture container can be adjusted by rotating the upper lid in the state of being combined. That is, if the lid is removed from the culture container for adjusting the ventilation amount, various bacteria may enter the culture container, but in the present invention, the ventilation amount can be adjusted while the lid is fitted in the culture container. Therefore, it is possible to prevent the invasion of various bacteria and the like into the culture container due to the removal of the lid, and to adjust the aeration amount into the culture container according to the change of the culture temperature. Moreover, since the upper surface of the upper lid has a relatively large area, the vent hole can be formed large.

Further, when the ventilation hole is directly opened and closed to adjust the ventilation amount into the culture container as described in claim 3, the opening and closing degree of the ventilation hole becomes the ventilation amount as it is. The air volume can be adjusted more accurately.

Further, as described in claim 4, a lid is formed by using two upper and lower lids fitted to each other, and the upper lid is configured to be rotatable in the circumferential direction of the lower lid. When the ventilation hole is provided in the peripheral portion of the lid and the opening is provided in the center of the lower lid, rotate the upper lid with the lid still fitted to the culture container as described above. In addition to being able to adjust the amount of aeration into the culture container, the length of the aeration path in the lid can be increased to increase the length of the filter through which the outside air passes, and high filtration performance can be obtained.

Further, as described in claim 5, the filter is sandwiched in a compressed state between the opening / closing wall and the fitting groove and between the upper end portion of the side wall of the fitting groove and the upper lid, and the filter is If it is configured to be molded into a substantially rectangular shape in a longitudinal sectional view, the upper lid is rotated with the lid still fitted to the culture container as described above, and the amount of ventilation into the culture container is increased. In addition to being able to adjust the air flow rate, the outside air will pass through the filter many times while flowing from the ventilation hole to the opening, and the same filtering performance as using a multilayer filter can be obtained while using one filter. Therefore, the filter can be efficiently used to obtain high filtration performance.

Further, as described in claim 6, the upper lid and the lower lid are provided with markers so that the rotational position of the upper lid can be confirmed, so that the upper lid and the lower lid can be fed into the culture container from the ventilation hole. The amount of ventilation can be adjusted accurately.
