Description

[Detailed description of the invention]

[0001]

The present invention aims to provide a mushroom cultivation paper stopper cap, particularly a mushroom cultivation paper stopper cap for an enoki mushroom culture bottle , which is suitable for automation .

[0002]

2. Description of the Related Art Conventionally, as a cap for a mushroom cultivation paper stopper, one having a lower lid fitted into a culture bottle mouth and an upper lid for stopping a paper stopper has been used (for example, Japanese Utility Model Publication No. 62-35317).
The structure is such that the upper lid is put on the lower lid in a cap shape, and the outer circumference of the paper is folded and bent between the peripheral edges of the cap to stop. Therefore, such a thing is called a paper stopper cap.

[0003]

With such a structure, the durability of the paper stopper is good. However, in assembling, the outer periphery of the flat paper is bent between the peripheries of the cap to be clamped. It takes a great deal of power and it is extremely difficult to assemble and replace a huge number of tens to hundreds of thousands. In addition, simply holding paper in a flat state between the upper and lower lid caps as in Japanese Utility Model Application Publication No. The paper had to be folded and pinched. Furthermore, as mushroom cultivation grows in scale,
To make cultivation automatic,
A durable mushroom cultivation paper stopper cap suitable for attaching
There was no.

[0004]

Therefore SUMMARY OF THE INVENTION In a paper plug cap comprising a top cover 2 which stop lower lid 1 and paper cover sheet 3 fitting to the culture bottle mouth, cylindrical stop ring 4 and the downward lid 1 bottle mouth Stop
In order ring top a and than stop ring and Kami受stay 8 having a lid retaining ring 5 and Kami受ring 6 and the air outlet 7 in the center of the large-diameter single piece, said upper lid retaining ring 5 inner peripheral
Constitutes a fitting recess 13 of the upper lid 2, and the upper lid 2 is fitted with the lower lid 1 .
The paper receiving ring 9 and the paper receiving stay 11 having an air port 10 in the center are integrally molded products. The paper receiving ring 6 and the paper pressing ring 9 Alternatively, a plurality of concave-convex fitting strips are used.

[0005]

With such a structure, the lower lid 1 has an upper lid stopper.
The upper cover 2 is inserted from above into the fitting recess 13 on the inner circumference of the
Since it is a structure that is fitted and integrated, it can be easily assembled, does not require large force for assembling, etc., and flat paper is sandwiched between the paper receiving ring 6 and the paper pressing ring 9 by the uneven fitting strip at the outer peripheral portion. As a result, invasion of various bacteria is prevented. Also cultivation bottle
Attach, remove, or plant paper stopper caps
Use a manipulator or a simple chuck to rearrange culture bottles
When performing, the paper stopper of the present invention is
Cultivation bottles with caps are easy to grip on the neck,
A retaining ring 4 that makes it difficult for the growing bottle to come off
There is a wide part consisting of the lower cultivation bottle neck and the upper part
There is a protrusion of the stop ring 5 to prevent falling
It is easy to handle with the chuck of the gasifier and does not fall.

1 to 3 show a lower cover 1, FIG. 1 is a plan view, FIG. 2 is an enlarged sectional view taken along line AA in FIG. 1, and FIG. 3 is an enlarged sectional view taken along line BB in FIG. As is apparent from these figures, the lower lid 1
Is a retaining ring 4 fitted to the outer periphery of the bottle opening 12 shown in FIG.
And an upper cover stopper ring 5, a paper receiving ring 6, and a paper receiving stay 8 having an air port 7 in the center. The stop ring 4 is provided with four stop ribs 4a on the inner wall of the stop ring 4 to the bottle mouth. Eight contact projections 4b are provided on the bottle mouth. A detachable slope 5a, which is an inclined groove, is provided at an upper edge portion of the upper lid stopper ring 5 to facilitate release of the fitted state with the upper lid 2. Further, four long communication holes 6a are provided at the boundary between the upper cover stopper ring 5 and the paper receiving ring 6 for discharging condensed water. The upper cover stopper ring 5 is also provided with a rib 5b for maintaining engagement with the upper cover. The upper surface of the paper receiving ring 6 is a holding projection 6b.

4 to 6 show the upper cover 2, FIG. 4 is a plan view, FIG. 5 is an enlarged sectional view taken along the line CC in FIG. 4, and FIG.
It is an expanded sectional view. As can be seen in FIG.
The paper cover ring 9 and a paper receiving stay 11 having an air port 10 in the center are integrally molded products. An engagement protrusion 9a with the lower cover 1 is provided on the outer periphery of the paper holding ring 9.
There is also a holding recess 9b for holding the paper stopper 3 between the holding lid 6 and the holding protrusion 6b on the upper surface of the lower lid 1. The projection 2a provided on the upper surface of the upper lid 2 has a function of preventing slippage with the bottom surface of the container when it is accommodated in the container and stacked.

FIG. 7 shows a use state of the paper stopper cap composed of the lower lid 1 and the upper lid 2. Nipping convex part 6b and nipping concave part 9b
A paper stopper cap comprising a lower lid 1 and an upper lid 2 sandwiching a paper stopper 3 between them is fitted into the bottle opening 12. A stopper rib 4 a on the inner wall of the stopper ring 4 is engaged with the thick edge of the bottle opening 12. The lower lid 1 and the upper lid 2 are not disengaged by the engagement of the rib 5b and the engagement projection 9a.

FIG. 8 shows a second embodiment of a paper stopper cap comprising a lower lid 1 and an upper lid 2. As shown in FIG. In this example, a recess is provided near the center of the holding projection 6b on the upper surface of the lower lid 1, and the holding recess 9b of the upper lid 2 is provided.
Are provided near the center of the paper stopper 3 so that the paper stopper 3 is sandwiched between them. The paper stopper is more firmly sandwiched by complicated irregularities, and at the same time, invasion of various bacteria is prevented. As shown in FIG. 9, the recess near the center of the holding projection 6b and the projection of the holding recess 9b of the upper lid 2 are small and sharp.
Further, the retention function is improved, and there is no invasion of various bacteria.
The fitting structure of the upper lid 2 and the lower lid 1 may be reversed in FIGS. 7 to 9 so that the upper lid 2 covers the outer surface of the upper lid retaining ring 5 of the lower lid 1.

[0010]

[Effects of the Invention] Since the mushroom cultivation paper stopper cap of the present invention has the above-described structure, a large amount of force is not required for clamping the paper stopper when assembling. Easy. Also, there is no invasion of various bacteria, and good mushroom growth can be achieved.
