Description

[Detailed description of the invention] (Industrial application field) The present invention relates to caps for mushroom cultivation bottles.

(Prior Art) Usually, in the artificial cultivation of mushrooms, cultivation is carried out by using a wide-mouthed cultivation bottle and filling the wide-mouthed bottle with a culture medium up to the height of the shoulder.

By the way, the inventor had previously developed a border food in which mushrooms are enlarged into a block shape by binding primordia made of mycelial tissue, and a method for cultivating the same, so that the mushrooms can be adapted to Western cuisine that uses knives and forks. , has filed a patent application (Japanese Unexamined Patent Publication No. 2-5854).

According to this method of cultivating border foods, the mycelial mass grows densely on the fungal bed surface. If grown in the inner space, the roots of the mycelial mass will be buried below the bottle mouth, making it difficult to harvest.

Therefore, as shown in FIG. 5, the inventor filled the culture medium up to a level where the top surface was slightly lower than the bottle opening of the cultivation bottle 10, then sterilized and inoculated the culture bottle using a conventional method. A cap (not shown) is placed on the cylindrical body for culturing, and when the fungal bed surface swells and a primordium consisting of hyphal tissue is generated after the cultivation is completed, the cap is removed and a new molded cylinder 12 with an enlarged upper part is formed. Attached to the bottle mouth, the primordium is elongated into the growth cylinder 12 while suppressing the growth of the bacterial mass in the growth chamber under conditions of oxygen deficiency and carbon dioxide excess compared to the normal atmosphere. The hyphae are bound together and grown into large hyphal masses.

At the time of harvesting, the molded cylinder 12 is opened at the overlapped portion and removed from the bottle mouth to expose the mycelial mass, which is then cut with a knife or the like and harvested.

(Problem to be solved by the invention) However, the above method has the following problems.

In other words, because the fungal bed surface is set at a high position that is slightly lower than the bottle opening, the space inside the bottle opening is narrow when the cap is placed over the bottle opening, and therefore sufficient oxygen cannot be secured and the growth of mycelium is hindered. This method has the problem that the process is slow and the culture period is long. Another problem is that when primordia are generated on the bacterial bed surface, the primordia adhere to the filter member of the cap, clogging the filter member and further deteriorating the culture conditions.

Therefore, the present invention was made to solve the above two problems.The purpose of the present invention is to improve the cap, secure a wide space inside the bottle opening during culture, and prevent clogging of the filter member. To provide a cap for a mushroom cultivation bottle that does not cause mushroom growth.

(Means for Solving the Problems) According to the present invention, the above object is achieved by providing a cap for a mushroom cultivation bottle that has a filter member and that fits over the bottle mouth to allow ventilation into the bottle mouth through the filter member. A mushroom cultivation bottle characterized in that a portion of the cap that fits into the bottle mouth and reaches the bottom surface of the cap is formed into a cylindrical portion having a length approximately corresponding to the length of the bottle neck of a normal cultivation bottle. This can be achieved by using a cap.

(Function) The part from the fitting part of the cap to the bottle opening to the bottom surface of the cap is formed into a cylindrical part with a length approximately equivalent to the length of the neck of a normal mushroom cultivation bottle, so it is easy to cultivate the medium. Even if the bottle is filled close to the mouth of the bottle, when the cap is fitted, there will be enough space above the medium to supply the sufficient amount of oxygen necessary for mycelial culture, and after the culture is complete, the mycelium will remain in the mycelial bed. Even if the hyphae rise from above, the hyphae will not adhere to the lower surface of the cap, and the filter member will not be clogged, allowing for good hyphae culture.

(Embodiment) A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows a cross-sectional view of cap 20. FIG.

22 is an upper lid part, and 24 is a lower lid part.

A fitting cylinder part 26 is vertically provided on the periphery of the upper lid part 22, and a protrusion part 28 is provided around the middle part of the outer wall of the fitting cylinder part 26.

Further, a flange portion 30 is provided on the upper edge of the upper lid portion 22 to protrude outward.

The lower lid part 24 includes a cylindrical part 34 in which a fitting part 32 to the bottle opening is formed at the lower end, a flange part 36 extending outward from the upper end of the cylindrical part 34, and a flange part 36 extending upwardly from the edge of the flange part 36. It consists of a vertically installed fitting cylinder part 38.

A protrusion 40 corresponding to the protrusion 28 described above is formed on the inner wall of the fitting cylindrical portion 38 .

A relatively large ventilation hole 42 for air circulation is opened in the upper surface of the lower lid part 24, and a relatively small ventilation hole 44 is also opened in the flange part 36.

A filter member 46 made of sponge is disposed within the fitting cylinder part 38 of the lower cover part 24, and the upper cover part 22 is fitted by the fitting cylinder part 38, and the protrusions 28.4 of each other are fitted together.
0 prevents removal and assembling.

The length of the lower lid part 240 cylinder part 34 is approximately the same as the length of the bottle neck of a normal mushroom cultivation bottle, for example, 25 mm.
It is formed to have a length of ~30 mm.

In addition, the fitting portion 32 at the lower end of the cylindrical portion 34 is connected to the cylindrical portion 34 in the illustrated example.
The lower end surface of the cylinder contacts the upper end surface of the bottle mouth when it is fitted into the bottle mouth, and the inner wall surface of the fitting part 32 contacts the outer end surface of the flange part 10b formed on the bottle mouth 10a. It is designed to fit tightly.

Although the fitting portion 32 is not shown, it is formed to have a bifurcated cross section.
The bottle opening 10a may fit tightly into the groove.

Next, an example of a method for cultivating border foods using the above-mentioned cap will be explained.

FIG. 2 shows a cultivation bottle 10, which has the shape of a normal wide-mouth bottle.

First, a culture medium is filled into the cultivation bottle 10 so that the top surface is located at a position slightly lower than the bottle opening of the cultivation bottle 10.

Thereafter, the above-mentioned cap 20 is fitted onto the bottle mouth, and sterilization is carried out in a conventional manner using a sterilization pot as appropriate.

Next, remove it from the sterilization pot, cool it, and then put cap 2 on it.
0, inoculate the seed culture onto the medium, cover with the cap again, and culture the mycelium in the culture chamber.

As is clear from Figure 3, there is a cap 20 above the medium.
The cylindrical portion 34 secures a space approximately the same size as the neck of a normal cultivation bottle, and within this space there are ventilation holes 44,
Outside air is circulated through the filter member 46 and the ventilation holes 42, thereby enriching the amount of oxygen and promoting the cultivation of mycelia.

In the case of the oyster mushroom fungus, the culture period is about 25 days, and at the end of this period, the mycelia actively proliferate in the medium, and the culture ends.

When the culture is completed, the bacteria are scraped if necessary (bacterium scraping is not necessary), and the cultivation bottle 10 is transferred to the growth chamber.

Keep the growth room dark. During the initial stage in the growth room, provide sufficient ventilation and provide plenty of fresh air to encourage further growth of mycelium. Then, the hyphae swell up from the surface of the medium, and a primordium consisting of hyphal tissue develops.

Even if primordia are generated in this way, there is sufficient space between the culture medium surface and the lower surface of the cap, so the conventional method in which primordia adhere to the lower surface of the cap and clog the filter member 46 is avoided. The problem will be resolved.

After the primordium is generated, the cap 20 is removed and the above-described molded cylinder 12 is attached to the bottle mouth in place of the cap 20. Thereafter, the mycelial mass can be grown within the molded cylinder 12 in the same manner as the method disclosed in Japanese Patent Application Laid-Open No. 2-5854.

In addition, although the above description has been made using an example of a food product, the present invention is not limited to this, and can also be used as a cap for a bottle for artificially cultivating ordinary mushrooms such as enokitake.

For example, in the case of enoki mushrooms, the cultivation bottle is filled with a culture medium almost up to the bottle opening, the cap 20 is fitted over the bottle opening in the same manner as described above, the mycelia are cultured, and the fruiting bodies are germinated after the bacteria are scraped. After germination of the fruiting bodies, it is recommended to wrap paper around the opening of the bottle as usual to allow the fruiting bodies to grow (see Figure 4).

Harvesting is easy by removing the wrapping paper to expose the roots.

Although various preferred embodiments of the present invention have been described above, the present invention is not limited to the above-mentioned embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. be.

(Effects of the Invention) As described above, according to the present invention, the portion from the fitting part of the cap to the bottle opening to the bottom surface of the cap has a length approximately equivalent to the length of the neck of a normal mushroom cultivation bottle. Because it is formed into a cylindrical part, even if the culture medium is filled close to the mouth of the cultivation bottle, there is enough space above the culture medium when the cap is fitted, and the sufficient amount of oxygen required for mycelial culture. Furthermore, even if the mycelium rises from the surface of the fungal bed after the cultivation is completed, the mycelium will not adhere to the bottom surface of the cap, and the filter member will not be clogged, allowing for good mycelial culture. Effective.
