Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a cap for mushroom cultivation bottles.

(Prior Art) Artificial cultivation of mushrooms such as enoki mushrooms and shimeji mushrooms has been widely practiced using cultivation bottles. In cultivation using this cultivation bottle, a culture medium consisting of sawdust, rice bran, etc. is filled into the cultivation bottle, and then sterilized, followed by inoculation of seed bacteria and the cultivation process begins.

Incidentally, the cultivation bottle filled with culture medium is covered with a cap until the cultivation process is completed. The purpose of this cap is to prevent bacteria from entering the cultivation bottle, to keep the medium filled in the cultivation bottle at an appropriate temperature and humidity, and to allow an appropriate amount of air to flow through the medium. It is also something that is provided.

After the sterilization process is carried out as described above, the inoculum is inoculated into each cultivation bottle. For example, in the case of shimeji mushrooms, a considerable amount of inoculum is inoculated due to the nature of mushrooms. Figure 4 shows the inoculum inoculation state in shimeji mushroom cultivation.As shown in the figure, culture medium 1 is filled up to near the bottle mouth, seed culture 2 is filled into the bottle mouth so as to cover culture medium 1, and the cap is filled with culture medium 1. When the cap 3 is fitted, the inoculum 2 is pressed against the inner lower surface of the cap 3 to prevent a gap from forming between the inoculum 2 and the cap 3. When cultivating shimeji mushrooms, if the seed fungus dries, the surface of the seed fungus solidifies and mushrooms will not form from the seed fungus. Therefore, it is an essential condition for cultivation that the starter fungus is not allowed to dry out, and for this reason, the starter fungus 2 and cap 3 are always Being in contact.

The caps shown in FIGS. 4 and 5 are conventional examples of caps for cultivating shimeji mushrooms.

The cap 3 shown in FIG. 4 is provided with a bulge 4 on the bottom surface of the cap for holding down the seed bacteria 2, and a vent 5 for allowing air to flow through the bottom surface of the bulge 4.
is provided. In addition, a ventilation material such as urethane foam 6 is housed in the upper part of the bulging portion 4 to allow the circulation of outside air and to maintain a constant environment in the cultivation bottle.

The cap shown in FIG. 5 has a bulge 4 on the lower surface of the cap having a smaller diameter than the cap shown in FIG.
It has been established.

(Problems to be solved by the invention) As mentioned above, caps for cultivation bottles are used to keep the seed bacteria and culture medium in an appropriate temperature and humidity environment. A bulge 4 is provided to prevent the seed from drying out, and a vent 5 is provided.
is provided.

However, as shown in FIGS. 4 and 5, in the conventional cap, the vent hole 5 and the urethane foam 6 are
Since the two parts are in direct contact with each other, there is a problem that the vent hole 5 is easily clogged with sawdust or the like.

In fact, after the culture medium is filled into the cultivation bottle, the cultivation bottle is capped and sterilized by heating in a sterilization pot, but at this time, the ventilation port 5 is blocked by the candy-like substance released from the decomposition of the medium. This often happens. Further, although the cap is properly cleaned with a brush, the use of the brush may end up clogging the vent 5 instead.

This is because the vent 5 is in direct contact with the urethane foam 6, so of course the urethane foam 6 itself must be replaced with a new one.
Although it is possible to eliminate the clog by re-drilling the vent hole, it is time consuming and usually the entire cap is replaced.

In addition, Fig. 6 shows an example in which a vent hole 5 is provided on the side surface of the bulging portion 4 in order to prevent the vent hole 5 from clogging as described above, but in this case, the culture medium surface is When the inoculum remaining in the center of the inoculum is pressed by the bulge 4, there is a problem that the inoculum tends to dry out because the inoculum and the vent 5 are close to each other.

The present invention was developed in view of the above-mentioned problems, and its purpose is to provide a cap for artificial cultivation of mushrooms such as shimeji mushrooms using cultivation bottles, which is easy to use and eliminates clogging of the ventilation holes. The purpose is to provide a good cap for mushroom cultivation.

(Means for Solving the Problem) The present invention has the following configuration to achieve the above object.

That is, a storage space is provided by sandwiching a ventilation material such as urethane foam between the cap body having a fitting wall that is attached to the mouth of a mushroom cultivation bottle, and the cap body at the upper part of the cap body. a lid body portion that is opened and fitted, and the lid body portion or the cap body portion is provided with an outside air communication portion that allows outside air to flow through the ventilation material stored in the storage space;
The top wall of the cap main body that supports the lower surface of the ventilation material is provided with a bulge that bulges in a direction in which the top wall bulges at the center in a direction that presses the inoculum planted on the medium material, and the bulge The top wall connected to the base of the part is provided with recesses in which the top wall is partially depressed in the direction of expansion of the bulge at predetermined intervals in the circumferential direction, and the radial direction of the recess is It is characterized in that a ventilation hole communicating with the inside of the bulge and opening in the side direction is provided at the end of the bulge.

(Function) When the cap is attached to the cultivation bottle, the inoculum is pressed by the swollen lower surface. In addition, outside air flows through the vent provided at the base of the bulge. Since the vent opens toward the side of the bulge and the vent does not come into direct contact with the vent material such as urethane foam, it is less likely to become clogged.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail based on the accompanying drawings.

FIG. 1 is a bottom view showing an embodiment of a mushroom cultivation bottle cap according to the present invention, FIG. 2 is a front view, and FIG. 3 is a side sectional view.

In FIG. 3, reference numeral 10 denotes a lid portion that covers the opening surface of the upper portion of the cap, and this lid portion 10 is removably fitted into an annular side wall 12 of the cap main body.

14 is a top wall of the cap main body, and the annular side wall 12 is provided around the periphery of the top wall 14. 16
is an annular inner wall provided inside the annular side wall 12.

A fitting wall 18 extends downward from the peripheral edge of the top wall 14 in a short cylindrical shape, and the cap is attached by fitting the fitting wall 18 to the mouth of the cultivation bottle.

Reference numeral 20 denotes a bulge projecting downward from the center of the ceiling wall 14, and 22 is a lower bottom portion of the bulge 20.
The lower bottom portion 22 is formed into a curved surface with a slightly raised central portion.

Reference numeral 24 denotes vent holes provided in the tapered side wall of the bulging portion 22, and in the embodiment, four vent holes are provided at equal intervals on the circumferential side of the bulging portion 20. As shown in FIGS. 2 and 3, this vent hole 24 is formed by recessing the ceiling wall 14 in the direction in which the bulge 20 expands, at a position connected to the top wall 14 at the base of the bulge 20. The recessed portion 26 is formed by opening the side surface of the tip thereof. The depression depth of the recess 26 is shallower than the amount of bulge of the bulge 20, and as shown in FIG. 3, the portion of the ceiling wall 24 in which the recess 26 is formed has a stepped shape.

Note that an outside air communication portion 28 is provided between the annular side wall 12 and the annular inner wall 16. Further, a support wall 30 having an upper edge at the same height as the top wall 14 is provided on the lower bottom portion 22 of the bulging portion 20 in a cross shape as shown in FIG.

When using the cap of this embodiment, the urethane foam 32 is stored in the ventilation material storage space formed between the top wall 14 and the lid part 10, and the inner area of the annular inner wall 16 is The urethane foam 32 is stored and used (within the shaded area in FIG. 2).
The support wall 30 reinforces the bulge 20 so that it does not deform, and supports the urethane foam 32 so that its lower surface does not enter into the bulge 20.

In the cap of the above embodiment, as described above, the vent 24 provided in the bulging part 20 communicates with the inside of the bulging part 20 and opens in the radial direction of the bulging part 20, so that sawdust etc. This has the effect of preventing the vent hole 24 from being blocked by sawdust or candy-like substances generated when the culture medium is sterilized.

Further, since the vent hole 24 and the urethane foam 32 do not come into direct contact with each other, it is possible to eliminate clogging of the vent hole due to direct contact between the urethane foam and the vent hole.

Furthermore, since the opening of the vent 24 is located at a position away from the lower bottom 22 of the bulge 20 that presses the seed bacteria, the seed bacteria will not dry out even when the seed bacteria are being pressed.

In this cap, the vent 24 is connected to the bulge 2.
By providing it on the side of 0, the opening area can be made relatively large, and in the example, the opening area can be made about 1.5 times that of the conventional example.

In addition, after inoculating the inoculum with shimeji mushrooms, when scraping the inoculum, only the central part of the inoculum is left and the surrounding inoculum is removed as shown by the broken line in FIG. By providing the lower bottom portion 22 in a spherical shape, it is possible to easily press the seed bacteria after scraping the bacteria.

Further, although the material of the cap in the above embodiment is not particularly limited, the cap in the above embodiment has a bulging portion 20 and a recessed portion 2.
6, etc., is configured to be a shape that can be easily cut out, and can be easily manufactured by molding using synthetic resin or the like.

The shape of the vent described above is not particularly limited to a cap for cultivating shimeji mushrooms, and can be similarly applied to caps for cultivating other mushrooms such as enoki mushrooms.

The present invention has been variously explained above using preferred embodiments, but the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. That's true.

(Effects of the invention) According to the cap for mushroom cultivation bottles of the present invention, by providing a vent that opens on the side of the bulge provided in the cap, the culture medium or inoculum, etc. to be filled in the cultivation bottle is This prevents the vents from clogging. In addition, since the vent is provided to open at the base of the bulge and is away from the bottom part that comes into contact with the inoculum, it has great effects such as allowing suitable mushroom cultivation without drying out the inoculum. .
