Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a cap for a mushroom cultivation bottle, and in particular,
The present invention relates to a mushroom cultivation bottle cap that allows air to flow uniformly into the cultivation bottle from the top surface of the lid.

(Conventional technology and its problems) In the artificial cultivation of mushrooms such as enoki mushrooms, a mushroom cultivation bottle is filled with a culture medium and heat sterilized, and then the inside and outside of the mushroom cultivation bottle are blocked to some extent to prevent bacteria. In order to prevent oxygen from entering the bottle and to introduce oxygen into the bottle to prevent oxygen deficiency, the opening of the bottle is plugged.

Conventionally, paper stoppers and lids made of synthetic resin have often been used as this type of stopper, but when using paper stoppers, the paper stopper is placed on the opening of the mushroom cultivation bottle. , it is necessary to fasten the circumference with a rubber ring, and this fastening work is extremely complicated. For this reason, in recent years, synthetic resin lids have been widely used. This synthetic resin lid is
A hollow part was provided in the flange part that bulged out on the outer periphery of the upper part of the lid, and a foamed urethane was placed in this hollow part as a filter, so that the outside air and the inside of the cultivation bottle passed through the hollow part.

In particular, the opening to the outside of the hollow portion is formed in the bottom surface of the bulging portion of the flange portion. Therefore, since air flows into the bottle from the opening at the outer periphery, the air flows along the wall surface of the bottle opening, which causes a problem in that the growth of the fruiting body in the central part is delayed.

Therefore, an object of the present invention is to provide a mushroom cultivation bottle cap that allows air to flow into the mushroom cultivation bottle from the top surface of the cap.

(Problems to be Solved by the Invention) The present invention eliminates the above problems and includes the following configuration.

As shown in FIG. 1, the lower part of the lid having a partition wall 16 in the middle is a fitting part 14 that fits into the bottle mouth 12a of the mushroom cultivation bottle 12, and a hollow part 22 is formed above the partition wall 16. Then, through holes (opening 12a, small hole 16b) are bored in the upper surface of the hollow part 22 and the partition wall 16,
It is characterized in that a filter member (urethane foam 30) is disposed in the hollow part 22 to allow air to flow into the pin 12 from the upper surface of the hollow part 22.

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

FIG. 1 shows a vertical cross-sectional side view of a cap for a mushroom cultivation bottle of the present invention, and FIG. 2 shows a side view.

10 is a cap fitted around the outer periphery of the bottle 12a of the mushroom cultivation bottle 12. The lower part of this cap 10 is a fitting part 14 that fits into the bottle opening 12a, and this fitting part 14 is partitioned off by a partition wall 16. Further, the partition wall 16 is formed to be larger than the diameter of the fitting portion 14, and the portion of the partition wall 16 outside the diameter of the fitting portion 14 is a flange portion 16A. A standing wall 18 stands up from the periphery of the flange portion 16A, and a closing lid 20 that covers the top surface of this standing wall 18 is fitted.

A hollow portion 22 is formed by the partition wall 16, the standing wall 18, and the closing lid 20.

The boundary line of the flange portion 16A of the partition wall 16 (fitting portion 1
Four arcuate pieces 24 are erected on the circumferential surface of the cylindrical member 4 (at opposing positions) (see FIGS. 3 and 4). In addition, through holes 26 communicating with the outside are formed in the flange portions 16A between the pieces 24 and the upright walls 18, respectively. Furthermore, the partition wall 16 has a communication hole 1 that communicates the inside of the cultivation bottle 12 and the hollow part 22.
6a are bored in eight rectangular shapes. In addition, the partition wall 16
A small hole 16b is bored in the center of the hole 16b, and a cylindrical body 28 stands upright surrounding the small hole 16b.

Furthermore, a foamed urethane 30 is disposed in the hollow portion 22 as a filter member. This urethane foam 30 is formed into a donut shape and is supported by the pieces 24, 24, 24, 24 and the cylindrical body 28. 32 is a holder, and this holder 32 includes a cylindrical portion 34 that fits into the cylindrical body 28, and a cylindrical portion 32.
It is formed from a flange portion 32b extending horizontally from the upper end edge of a.

At the center of the closing lid 20 is a flange portion 3 of a holder 32.
An opening 20a smaller in diameter than 2b is bored. Then, while placing the craft IE 34 as a filter member on the flange portion 32b of the holder 32, the closing lid 20
is fitted onto the upright wall 18.

Since the cap 10 is constructed as described above, air flowing from the through hole 26 formed in the flange portion 16A passes through the urethane foam 30 to the communication hole 16a.
・Flows into the mushroom cultivation bottle 12 from the water. Also closed lid 2
The air flowing in from the opening 20a of
Air flows into the center of the bin 12a of the mushroom cultivation bin 12 through the.

Further, the urethane foam 30 can be removed from the cap 10 by removing the closing lid 20 and washed.

In the above embodiment, the cylindrical body 28 erected on the partition plate 16 is not necessarily required, and only the holder 32 may be used. Furthermore, the kraft paper 34 may be laid on the top surface of the partition wall 16.Furthermore, the entire cap 10 may be formed into a cylindrical shape, and the flange portion 16A of the partition wall 16 does not necessarily have through holes.
It is not necessary to drill 6.

FIGS. 5 and 6 show modified examples. In this example, the shape of the communication hole 16a (including the small hole 16b) formed in the partition wall 16 is different, and the cylinder body 28 is not provided upright in the partition wall 16.The other configuration is the same as that of the above embodiment. It is composed of

(Effects of the Invention) As described above, this invention allows air to flow into the mushroom cultivation bottle from the top surface of the cap, so it has great effects such as being able to uniformly supply air to the mushroom cultivation bottle. play.

Although the present invention has been variously explained above with reference to preferred embodiments, 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. It is.
