BACKGROUND OF THE INVENTION
The present invention relates to a cap for a mushroom cultivation container.
[0002]
[Prior art]
Conventionally, in the cultivation process of mushrooms, as shown in FIG. 7, a bottle-shaped mushroom cultivation container 23 is filled with a mushroom medium material 24 and inoculated with an inoculum, and the mushroom cultivation container 23 is covered with a cap 100. The method of culturing for a predetermined period is used. This cap 100 for mushroom cultivation containers does not completely seal the mushroom cultivation container 23 but is provided so that air can flow through a filter.
[0003]
Next, the structure of the cap 100 for mushroom cultivation containers is demonstrated. FIG. 4 is an exploded view showing a configuration of the mushroom cultivation container cap 100. As shown in the figure, a cap 100 for a mushroom cultivation container is composed of a cap body 11 and an upper lid 12, and is used with a filter 14 mounted between them. FIG. 5 is a top view of the cap 100 for a mushroom cultivation container in which a filter is mounted, 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 molded by plastic molding.
[0004]
The cap body 11 is provided with a tubular upper lid fitting portion 21 provided upward from the outer peripheral portion of the circular plate-shaped inner lid portion 20, and the lower surface of the inner lid portion 20 is concentric with the upper lid fitting portion 21. A cylindrical container fitting portion 19 is disposed in the container. The upper lid fitting portion 21 has a larger diameter than the container fitting portion 19. Further, the upper lid fitting portion 21 is provided with an inner peripheral projection 21a over the entire circumference inside the opening end.
Further, a plurality of supporting ribs 16 are erected on the upper surface of the inner lid portion 20 at equal intervals so as to draw a circular arc that is concentric with the container fitting portion 19 and has substantially the same diameter or slightly smaller diameter. .
[0005]
Further, the inner lid portion 20 outside the supporting rib 16 is provided with a first vent hole 17 opened in a slit shape (see FIG. 5). A plurality of second ventilation holes 18 that are circularly open are provided at positions spaced apart from the support ribs 16 by a predetermined distance on the inner side of the support ribs 16 of the inner lid portion 20.
[0006]
On the other hand, the upper lid 12 is formed by disposing a main body fitting portion 22 and a plurality of pressing ribs 15 on the same surface side of a circular plate-like lid body 26.
The cylindrical main body fitting portion 22 is disposed concentrically with the lid body 26 at a position slightly inside from the outer periphery of the lid body 26. An outer peripheral protrusion 22 a is provided on the outer peripheral surface of the main body fitting portion 22 over the entire periphery.
A plurality of pressing ribs 15 are provided so as to extend radially from the center of the lid body 26.
[0007]
The filter 14 made of synthetic resin, paper, nonwoven fabric, or the like is a circle having a size so as to cover the plurality of second vent holes 18 at a time within the plurality of supporting ribs 16 on the upper surface of the inner lid portion 20. It is formed into a sheet shape.
Further, the filter 14 has air permeability that enables air necessary for hyphal growth, and does not allow passage of a size larger than a predetermined size so as to prevent invasion of germs that inhibit the hypha culture. It has a function.
[0008]
The cap 100 for a mushroom cultivation container having the above-described configuration is configured so that the main body fitting portion 22 is the upper lid fitting portion while the filter 14 is placed inside the plurality of supporting ribs 16 on the upper surface of the inner lid portion 20. The cap body 11 and the upper lid 12 are fitted together and used.
At this time, the outer peripheral protrusion 22a of the main body fitting portion 22 and the inner peripheral protrusion 21a of the upper lid fitting portion 21 are engaged to prevent the cap main body 11 and the upper lid 12 from being securely fitted. . In this state, the outer peripheral end surface of the lid body 26 is aligned with the outer surface of the upper lid fitting portion 21. Further, the supporting rib 16 abuts on the lid body 26, and the pressing rib 15 presses the filter 14 against the inner lid portion 20 from above. Further, the outer end portions 15 b of the plurality of pressing ribs 15 arranged in a radial shape are located in the vicinity of the supporting ribs 16.
[0009]
When using the mushroom cultivation container cap 100 to which the filter 14 is attached, the bottle mouth of the mushroom cultivation container 23 is fitted into the container fitting portion 19 for use. At this time, a plurality (for example, four) of protrusions (not shown) are provided at equal intervals on the inner peripheral surface of the container fitting portion 19, and are related to the outer peripheral protrusions near the bottle mouth of the mushroom cultivation container 23. Since it fits, it is securely inserted into the bottle mouth.
[0010]
The flow of air inside and outside the mushroom cultivation container with the mushroom cultivation container cap 100 fitted therein is schematically shown, for example, by an arrow A in FIG. 5 or an arrow B in FIG. That is, the air is mainly circulated through the first vent hole 17, the gap 27 between the two support ribs 16, and the second vent hole. At this time, since the filter 14 is disposed so as to cover the second ventilation hole, the air passes through the filter 14 and can prevent invasion of germs and the like into the mushroom cultivation container.
[0011]
[Problems to be solved by the invention]
However, since the filter 14 is formed in a thin sheet shape, the filter 14 is easily deformed, and the surface may be undulated including moisture. When the filter 14 is undulated and deformed at the outer peripheral portion thereof, a portion where the filter 14 is not in close contact with the inner lid portion 20 is generated between the plurality of pressing ribs 15 arranged radially. If there is a portion in the outer peripheral portion of the filter 14 that is floating from the inner lid portion 20, the air circulates inside and outside the mushroom cultivation container without passing through the filter 14. With this, it is not possible to satisfactorily prevent invasion of germs and the like into the mushroom cultivation container.
[0012]
Accordingly, the present invention has been made to solve these problems, and an object of the present invention is to provide a cap for a mushroom cultivation container in which the flow of air inside and outside the mushroom cultivation container is surely made through a filter. There is to do.

DETAILED DESCRIPTION OF THE INVENTION
Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is an exploded view showing a configuration of a cap for a mushroom cultivation container according to the present invention. FIG. 2 is a top view of the cap for a mushroom cultivation container according to the present invention, and shows the 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 a mushroom cultivation container of the present invention is characterized by providing a filter pressing ring 13, and FIGS. 4, 5, and 6 are used for other configurations. Since it is the same as the cap 100 for the mushroom cultivation container described above, the same number is attached in the figure and the description is omitted.
[0017]
A plurality of support ribs 16 (four in the figure) are arranged in the cap body 11, and one second is provided on the inner side of each of the support ribs 16 by the same distance 28 (see FIG. 2) from the support rib 16. 18 is arranged. A plurality (four) of the second vent 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 substantially the same diameter. 20 is accommodated inside a plurality of support ribs 16. Thereby, the filter 14 can be easily accommodated without being obstructed by the supporting ribs 16, and can cover the plurality of second vent holes 18 at a time with a margin.
[0018]
With respect to the cap body having the above-described configuration, the filter pressing ring 13 has an outer diameter that is substantially the same as the diameter of the filter 14, and a width that is substantially the same as the distance 28 as shown in FIG. 13a.
As shown in FIGS. 2 and 3, such a filter pressing ring 13 has a cap body 11 sealed with an upper lid 12 in a state of being overlapped on the outer periphery of the filter 14 inside a plurality of supporting ribs 16. Have been used.
At this time, the plurality of pressing ribs 15 arranged in a radial pattern have a length that extends to the vicinity of the supporting rib 16 so as not to interfere with the supporting rib 16. 14 is sandwiched between the outer end portion 15 b side of the plurality of pressing ribs 15 and the inner lid portion 20.
[0019]
Therefore, the thickness 13 h of the filter pressing ring 13 is formed to a thickness that does not hinder the fitting of 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.
Thus, when the filter pressing 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 support rib 16, which is an air passage. The outer shape is not completely blocked.
[0020]
Further, the filter pressing ring 13 has a certain amount of pressure so that the outer peripheral portion of the filter 14 superimposed on the filter pressing ring 13 is pressed against the inner lid portion 20 by the pressing rib 15 as uniformly as possible through the filter pressing ring 13. It has rigidity.
[0021]
In the mushroom cultivation container cap 10 equipped with the filter 14 and the filter pressing ring 13 according to the above configuration, the outer periphery of the filter 14 is pressed so as to be in close contact with the inner lid 20 by the pressing rib 15 via the filter pressing ring 13. It is done. Therefore, even if the filter 14 is in a deformed state in which it undulates, it does not float from the upper surface of the inner lid portion 20 at the outer peripheral portion. As a result, when the outer peripheral portion of the filter 14 is in close contact with the upper surface of the inner lid portion 20 over the entire periphery, the plurality of second vent holes 18 are covered with the single filter 14 without any gaps. In addition, since the filter press ring 13 does not hinder the flow of air inside and outside the mushroom cultivation container, the flow of air is surely made through the filter 14.
[0022]
The present invention is not limited to the above embodiments, and many modifications can be made without departing from the spirit of the invention.
In order to ensure the air flow inside and outside the mushroom cultivation container through the filter 14, the outer periphery of the portion covering the second ventilation hole of the filter 14 is internally connected by the pressing rib 15 via the filter pressing ring 13. What is necessary is just to press the lid | cover part 20 and closely_contact | adhere. In addition, "the outer periphery of the part which covers the 2nd vent hole of a filter" here shows the outer periphery of the part which covers the several 2nd vent hole collectively, when the 2nd vent hole is provided with two or more. .
Therefore, even if the filter pressing ring 13 has an outer diameter smaller than the diameter of the filter 14, it may have a size that is superimposed on the outer periphery of the portion of the filter 14 that covers the second vent hole. At this time, the filter pressing ring 13 may be placed on the filter 14 so as to surround the portion of the filter 14 covering the second vent hole, and the cap body 11 and the upper lid 12 may be fitted in this state.
[0023]
In addition, when the cap main body 11 and the upper lid 12 are fitted, if the holding rib 15 is disposed at a position relatively away from the supporting rib 16 or if the distance 28 is a very small length, it is sure. In addition, the width 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 pressing rib 15 via the filter pressing ring 13, and the second vent hole 18 is somewhat blocked. May be.
Alternatively, the filter pressing ring 13 may be larger than the outer diameter of the filter 14 and completely cover the outer periphery of the filter. In this case, the wavy filter 14 can be brought into close contact with the inner lid portion.
[0024]
Furthermore, when the cap main body 11 and the upper lid 12 are fitted, the filter pressing ring 13 is attached to the lower ends of the plurality of pressing ribs 15 so that the filter pressing ring 13 satisfactorily surrounds the portion that covers the second vent hole of the filter 14. It may be fixed to the part. According to this, it is possible to prevent forgetting to store the filter pressing ring 13 in the cap 10 for a mushroom cultivation container.
[0025]
FIG. 8 is a perspective view of a cap body 31 having another shape. The cap main body 31 is the same as the cap main body 11 shown in FIG. 1 except for the shape of the second vent hole 18. In the cap body 31, a plurality (four in the figure) of supporting ribs 16 are arranged so as to draw an arc concentric with the inner lid portion 20. On the other hand, a plurality (four in the figure) of the second ventilation holes 18 are concentric with the inner lid portion 20 on the inner side of the support ribs 16 and from one circle having a smaller diameter than the arc of the support ribs 16 described above. An inner lid portion 20 is formed in a plurality of fan shapes to be formed. In other words, the second vent hole 18 is disposed at a certain distance from the support rib 16.
The present invention is also suitable for such a cap body 31, and the outer periphery of the portion covering the second vent hole of the filter can be satisfactorily adhered to the inner lid portion using the filter holding ring as described above. it can.
Anyway, according to this invention, since the existing cap for mushroom cultivation containers can be used, it is advantageous.
[0026]
【The invention's effect】
According to the present invention, even if there is a wave-like deformation in the filter, the outer periphery of the portion covering the second vent hole of the filter can be satisfactorily adhered to the inner lid portion, and air circulation inside and outside the mushroom cultivation container can be achieved. Certainly done through a filter. Thereby, invasion of various germs and the like into the mushroom cultivation container can be prevented.
