Conventionally, in a mushroom culturing process, as shown in FIG. 7, a bottle-shaped mushroom cultivation container 23 is filled with a mushroom culture medium 24, inoculated with a seed fungus, and the mushroom cultivation container 23 is covered with a cap 100. A method of culturing for a predetermined period is used. The mushroom cultivation container cap 100 does not completely seal the mushroom cultivation container 23, but is provided so that air can flow through a filter.
[0003]
Next, the configuration of the mushroom cultivation container cap 100 will be described. FIG. 4 is an exploded view showing a configuration of the cap 100 for a mushroom cultivation container. As shown in the figure, a cap 100 for a mushroom cultivation container includes a cap body 11 and an upper lid 12, and a filter 14 is mounted between the two. FIG. 5 is a top view of the mushroom cultivation container cap 100 with the filter mounted therein, and shows the positional relationship of each part. FIG. 6 is a sectional view thereof.
Each part of the cap body 11 and the upper lid 12 is integrally formed by plastic molding.
[0004]
The cap body 11 is provided with a cylindrical upper lid fitting portion 21 provided upward from the outer peripheral portion of the circular plate-shaped inner lid portion 20, and is concentric with the upper lid fitting portion 21 on the lower surface of the inner lid portion 20. Is provided with a cylindrical container fitting portion 19. The upper cover fitting portion 21 is formed to have a larger diameter than the container fitting portion 19. Further, the inner peripheral projection 21a is provided on the inner periphery of the opening end of the upper lid fitting portion 21 over the entire periphery.
On the upper surface of the inner lid portion 20, a plurality of support ribs 16 are erected at equal intervals so as to draw an arc of substantially the same diameter or a slightly smaller diameter concentric with the container fitting portion 19. .
[0005]
Further, a first ventilation hole 17 which is opened in a slit shape is provided in the inner lid portion 20 outside the supporting rib 16 (see FIG. 5). Further, a plurality of second ventilation holes 18 that are open in a circular shape at a position separated from the support rib 16 by a predetermined distance are provided inside the support rib 16 of the inner lid portion 20.
[0006]
On the other hand, the upper lid 12 is formed by arranging the main body fitting portion 22 and the plurality of pressing ribs 15 on the same surface side of the circular plate-shaped lid 26.
The cylindrical main body fitting portion 22 is disposed concentrically with the lid 26 at a position slightly inside the outer periphery of the lid 26. Further, on the outer peripheral surface of the main body fitting portion 22, an outer peripheral projection 22a is provided over the entire periphery.
A plurality of pressing ribs 15 are provided so as to extend radially from the center of the lid 26.
[0007]
The filter 14 made of synthetic resin, paper, nonwoven fabric, or the like has a circular shape large enough to cover a plurality of the second ventilation holes 18 at a time inside the plurality of support ribs 16 on the upper surface of the inner lid 20. Is formed in a sheet shape.
In addition, the filter 14 has air permeability that allows the flow of air necessary for the growth of mycelium, and does not allow a filter having a size larger than a predetermined size to pass therethrough so as to prevent invasion of various bacteria that inhibit culture of the mycelium. Has a function.
[0008]
The mushroom cultivation container cap 100 having the above-described configuration is configured such that the main body fitting portion 22 is connected to the upper lid fitting portion with the filter 14 placed on the upper surface of the inner lid portion 20 and inside the plurality of supporting ribs 16. The cap body 11 and the upper lid 12 are fitted and used.
At this time, the outer peripheral projection 22a of the main body fitting portion 22 and the inner peripheral projection 21a of the upper lid fitting portion 21 are prevented from coming off, and the cap main body 11 and the upper lid 12 are securely fitted. . In this state, the outer peripheral end surface of the lid 26 is aligned with the outer surface of the upper lid fitting portion 21. Further, the supporting rib 16 is in contact with the lid 26, and the pressing rib 15 presses the filter 14 against the inner lid 20 from above. The outer end portions 15 b of the plurality of pressing ribs 15 arranged radially are located near the supporting ribs 16.
[0009]
When using the cap 100 for the mushroom cultivation container to which the filter 14 is attached, the bottle mouth of the mushroom cultivation container 23 is fitted into the fitting portion 19 for use. At this time, a plurality (for example, four) of projections (not shown) are provided at equal intervals on the inner peripheral surface of the container fitting portion 19, and the projections (not shown) relate to the outer peripheral projections near the bottle mouth of the mushroom cultivation container 23. Because they fit together, they are securely fitted to the bottle mouth.
[0010]
The flow of air inside and outside the mushroom cultivation container to which the mushroom cultivation container cap 100 is fitted is schematically indicated by, for example, an arrow A in FIG. 5 and an arrow B in FIG. That is, the air is mainly circulated through the first ventilation hole 17, the gap 27 between the two supporting ribs 16, and the second ventilation hole. At this time, since the filter 14 is provided so as to cover the second ventilation hole, the air passes through the filter 14 and the invasion of various bacteria and the like into the mushroom cultivation container can be prevented.
[0011]
[Problems to be solved by the invention]
However, since the filter 14 is formed in a thin sheet shape, it is easily deformed, and the surface may undulate due to the inclusion of moisture and the like. When the filter 14 is wavy and deformed at its outer peripheral portion, a portion where the filter 14 is not in close contact with the inner lid portion 20 occurs between the plurality of pressing ribs 15 arranged radially. If there is a portion of the outer periphery of the filter 14 that is floating from the inner lid 20, air flows inside and outside the mushroom cultivation container without passing through the filter 14. In this case, invasion of various bacteria and the like into the mushroom cultivation container cannot be satisfactorily prevented.
[0012]
Therefore, the present invention has been made to solve these problems, and it is an object of the present invention to provide a cap for a mushroom cultivation container in which the flow of air inside and outside the mushroom cultivation container is ensured through a filter. Is to do.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is an exploded view showing a configuration of a mushroom cultivation container cap according to the present invention. FIG. 2 is a top view of the cap for mushroom cultivation container according to the present invention, showing a positional relationship of each part. FIG. 3 is a sectional view thereof.
[0016]
As shown in FIGS. 1, 2 and 3, the cap 10 for mushroom cultivation containers of the present invention is characterized in that a filter holding ring 13 is provided, and for other configurations, FIGS. Since it is the same as the cap 100 for the mushroom cultivation container described above, the same reference numerals are given in the figures and the description is omitted.
[0017]
A plurality of (four in the figure) supporting ribs 16 are provided in the cap body 11, and one inside each is provided with the same distance 28 (see FIG. 2) from the supporting rib 16 to form the second ventilation hole. 18 are provided. The plurality (four) of the second ventilation holes 18 are formed by opening the inner lid portion 20 in the same circular shape.
The filter 14 is made of synthetic resin, paper, nonwoven fabric, or the like, and is formed in a circular sheet shape having a diameter slightly smaller than the inner diameter of the support rib 16 formed in an arc shape, or a substantially same diameter. 20 are housed inside the plurality of supporting ribs 16. Thereby, the filter 14 can be easily stored without being hindered by the supporting ribs 16, and can cover the plurality of second ventilation holes 18 at a time with a margin.
[0018]
With respect to the cap body having the above configuration, the filter holding ring 13 is formed so that the outer diameter thereof is substantially the same as the diameter of the filter 14 and, as shown in FIG. 13a.
As shown in FIGS. 2 and 3, the cap main body 11 is sealed by the upper lid 12 in a state where the cap main body 11 is overlapped on the outer peripheral portion of the filter 14 inside the plurality of support ribs 16 as shown in FIGS. Being used.
At this time, since the plurality of pressing ribs 15 arranged radially have a length extending to the vicinity of the supporting rib 16 so as not to interfere with the supporting rib 16, the filter pressing ring 13 14, the plurality of holding ribs 15 are sandwiched between the outer end portions 15 b of the holding ribs 15 and the inner lid portion 20.
[0019]
Therefore, the thickness 13 h of the filter holding ring 13 is formed to a thickness that does not hinder the fitting between the cap body 11 and the upper lid 12. Further, the thickness 13h is of course a thickness that does not completely close the gap 27.
As described above, when the filter holding ring 13 is mounted in the mushroom cultivation container cap 10 together with the filter 14, the gap 27 between the second ventilation hole 18 and the supporting rib 16, which is an air passage, is provided. Is formed so as not to completely obstruct the.

Here, the “outer perimeter of the portion covering the second vent hole” of the filter indicates the outer perimeter of the portion covering the plurality of second vent holes collectively when a plurality of second vent holes are provided. .
Therefore, even if the filter holding ring 13 has an outer diameter smaller than the diameter of the filter 14, the filter holding ring 13 may have a size that is superimposed on the outer periphery of the portion of the filter 14 that covers the second ventilation hole. In this case, it is preferable that the filter holding ring 13 is placed on the filter 14 so as to surround a portion of the filter 14 that covers the second ventilation hole, and the cap body 11 and the upper lid 12 are fitted in this state.
[0023]
Also, when the cap body 11 and the upper lid 12 are fitted together, if the pressing rib 15 is arranged at a position relatively distant from the supporting rib 16, or if the distance 28 is a very small length, it is ensured. The length of the width 13a is made larger than the distance 28 so that the outer peripheral portion of the filter 14 is pressed by the holding rib 15 via the filter holding ring 13, so that the second ventilation hole 18 is somewhat closed. May be.
Further, the filter holding ring 13 may have a larger outer diameter than the outer diameter of the filter 14 and may completely cover the outer peripheral portion of the filter. In this case, the corrugated filter 14 can be brought into close contact with the inner lid.
[0024]
Furthermore, when the cap main body 11 and the upper lid 12 are fitted together, the filter holding ring 13 is attached to the lower ends of the plurality of holding ribs 15 so that the filter holding ring 13 satisfactorily surrounds the portion covering the second ventilation hole of the filter 14. It may be fixed to a part. According to this, it is possible to prevent the user from forgetting to store the filter holding ring 13 in the mushroom cultivation container cap 10.
