Description

[Detailed description of the invention] This invention relates to a cap for a bottle for mushroom cultivation, and is particularly suitable for the cultivation of Japanese shimeji mushrooms. Pressure is applied under moderate pressure conditions that can prevent excessive drying or excessive humidity of the mushroom-growing surface, and as a result, improvement in mushroom quality and harvest rate can be expected.

The method of artificially cultivating honshimeji mushrooms is not fundamentally different from that of other mushrooms such as enoki mushrooms, but in terms of cultivation techniques, it is different from the following methods of artificially cultivating other mushrooms. They have somewhat different singularities.

(b) To prevent drying of the mushroom-growing surface 3 on the surface of the seed bed 2 filled to the vicinity of the mouth of the cultivation bottle 1 as shown in Figure 1a, and as shown in Figure 1b as a later step. In order to prevent the mushroom-growing surface 3 from losing its shape when scraping the bacteria, a cap 4 such that an inner lid 5 compresses the mushroom-growing surface 3 is attached to the mouth of the bottle.

(b) The cultivation period for hon-shimeji mushrooms is about 50 days longer than that for other mushrooms such as enoki mushrooms (about 55 days for enoki mushrooms and about 55 days for hon-shimeji mushrooms).
100 days), in the above cultivation bottle 1, if too much air is supplied into the bottle, the mushroom-growing surface 3 will become too dry.
On the other hand, if it is too low, there will be a lack of oxygen and excessive humidity, creating conditions that make it easy for bacteria to invade. Therefore, the air supply holes 6 provided in the inner lid 5 of the cap 4 need to be smaller in diameter and fewer in number than the pores in the cap of other mushroom cultivation bottles, but if the pores are small, the seed bed Mushroom growth surface 3
The pores 6 are likely to become clogged at the contact surface with the pores, and it is necessary to devise a position where the pores 6 are provided to prevent clogging.

(c) In order to produce high-quality mushrooms, as shown in Figure 1b, after the specified ripening period has elapsed, the cap 4 is removed and a portion of the mushroom-producing surface 3 of the seed bed is left in place to remove unnecessary material. Bacteria scraping is performed by scraping off the surrounding area 9.

In this way, in the cultivation method of Hon Shimeji mushrooms, it is basically essential to hold down the mushroom-growing surface of the seed bed with a cap to prevent it from drying out, and to reduce the amount of air entering compared to other mushroom cultivation methods. required as a condition of

In order to satisfy these conditions, as shown in Fig. 2, the cap of the conventional bottle for cultivating shimeji mushrooms is embedded in the seed bed part 2 at the center of the lower surface of the inner lid 5 to form a mushroom-growing surface 3. A protrusion 7 is provided to compress the seed bed, and the protrusion 7 does not come into contact with the mushroom generation surface 3 of the seed bed.
It has been proposed that air holes 6 are provided in the inner cover 5 around the periphery of the inner lid 5 (Utility Application No. 158227-1987).

However, in the above-mentioned improved cap, since the mushroom-growing surface 3 is compressed and hardened by the protrusion 7, the mushroom-growing surface 3 loses its shape around the mushroom-growing surface 3 during subsequent bacterial scraping. Although it has the advantage that it can be removed without any damage, it has the disadvantage that the protrusion 7 completely compresses the mushroom-growing surface 3, which hinders the growth of bacteria on the mushroom-growing surface 3, resulting in a delay in bacterial circulation. It was found that there were problems in terms of economic efficiency when viewed as a cultivation method.

The purpose of this proposal is to solve the problems of conventional cultivation bottle caps while taking into consideration the various conditions of the Honshimeji cultivation method as described above. A ring-shaped protrusion that digs deeply from the lower surface of the inner lid toward the mushroom-producing surface at the center of the seed bed in the bottle mouth is provided on the center side of the pore, and the mushroom is surrounded by the annular protrusion. On the inside, the lower surface of the inner lid is slightly protruded downward than the peripheral part of the inner lid where the pores are provided, so as not to compress the mushroom-growing surface too strongly.
It is characterized by providing a covering portion for the mushroom-growing surface.

Next, the present invention will be explained with reference to the embodiments shown in FIG. It is. The cap 14 consists of an outer cover 18 and an inner cover 15 that are arranged horizontally in parallel, and the inner cover 15 is located inside an inner circumferential wall 20 having an inner diameter large enough to fit on the outer circumferential surface of the bottle mouth 19. It is set in. Further, at the center of the lower surface of the inner lid 15, a peripheral edge 22 of the tip protrudes toward the inside of the bottle spout 19 so as to dig deeply into the mushroom-growing surface 13 of the seed bed 12 filled in the bottle spout 19. An annular protrusion 21 is provided around the periphery. A vertical pore 16 is provided around the periphery of the inner lid 15 to introduce air into the bottle mouth 19 from a filter 23 arranged between the inner lid 15 and the outer lid 18. The annular protrusion 21 is protruded so as to be located closer to the center than the air hole 16 on the lower surface of the inner lid 15 .

Further, on the inside surrounded by the annular protrusion 21, the lower surface of the inner lid is slightly protruded below the peripheral part where the pores 16 are provided, so that the inner lid 15
A flat covering part 17 is provided such that the central lower surface of the seed bed part 12 contacts the mushroom-producing surface 13 at the center of the seed bed part 12. Note that this covering portion 17 may be solid as shown in FIG. 3, or may be hollow.

The outer cover 18 is provided on the upper edge of the inner circumferential wall 20 of the inner cover like a known one, and the above-mentioned outer cover 18 is provided in the space between the inner cover 15 and the outer cover 18 surrounded by the upper edge of the inner circumferential wall 20. A filter 23 made of urethane such as the one shown in FIG. An air inflow slit 25 is provided between the outer peripheral wall 24 of the outer lid 18 and the inner peripheral wall 20, and air holes 26 are provided at the upper edge of the inner peripheral wall 20.
The outside air passes through the slit 25 through the pores 26, and is supplied to the seed bed section 12 inside the bottle through the pores 16 of the inner lid 15 after removing germs with the filter 23.

As described above, the cap 14 according to the present invention has a tip periphery 22 located at the center of the lower surface of the inner lid 15 and a seed bed portion 12.
An annular protrusion 21 that digs deeply into the mushroom-producing surface 13 of the annular protrusion 2 is provided, and the lower surface of the inner lid surrounded by the annular protrusion 21
As shown in FIG.
When the cap 14 is placed in the bottle opening 19, the annular protrusion 21 digs deeply into the seed bed 12, and the covering part 17 covers the mushroom-growing surface 13 at the center of the seed bed.
Contact coating is carried out with moderate contact pressure without compressing too strongly. In this case, the covering part 17 comes into contact with the mushroom-producing surface 13, but the peripheral part of the inner lid 15 where the pores 16 are formed outside the annular protrusion 21 has a thinner wall thickness than the covering part 17. A space is formed between the lower seedbed 12 and the pores 1 provided at the periphery of the inner lid toward the inside of this space.
6, air sterilized by the filter 23 is introduced.

However, since the annular protrusion 21 is deeply wedged into the seed bed 12, the air introduced into this space is absorbed by the wall-like protrusion 21 embedded in the seed bed 12. , the direct inflow toward the inner covering part 17 is blocked, and a very small amount of air that passes under the seed bed part 12 along the surface of the annular protrusion 21 is blocked inside the covering part 17. It will be passed to As a result, the mushroom-growing surface 13 of the seed bed part that comes into contact with the covering part 17 is given conditions for introducing an extremely small amount of air, so that it does not become excessively dry or humid, and the surface is prevented from being excessively compressed. The conditions are optimal for the growth of the seed bacteria without causing hardening, and the conditions surrounding the bacteria can be made significantly better than in the case of conventional caps of this type.

Further, since an annular protrusion 21 is provided on the outer periphery of the covering portion 17, which digs deeply into the seed bed portion 12, when the cap 14 is removed after a predetermined ripening period, as shown in FIG. An annular groove 27 is formed on the outside of the mushroom-producing surface 13 of the seed bed 12 after the annular protrusion 21 has exited. Therefore, when scraping the seed bed 12 as shown in FIG. You can easily set it up without having to do anything. Of course, the operation of scraping off the seed bed 12 can be carried out extremely easily due to the presence of the annular groove 27 between it and the mushroom-producing surface 13.

As described above, according to the cap of the present invention, compared to conventional caps of this kind, the mushroom-growing surface 13 can be properly protected by the covering part 17 during the growing period of the seed bed part 12, and the annular protrusion part 21 can be properly protected. With this arrangement, the fungus scraping process can be performed easily and efficiently, and the quality and harvest rate of mushrooms can be expected to be improved.
