Description

The present invention relates to a cap for a cultivation container for mushrooms, and particularly relates to a form of a cap surface.

A mushroom cultivation container containing a medium with a moisture content and humidity suitable for culturing is sterilized at 100 ° C. to 120 ° C. in a heating kettle, and then cooled to 15 ° C. to 20 ° C. by a cooling room or water cooling. Is done. Thereafter, the sterilized and cooled cultivation container is inoculated with the inoculum, and the culture process is started.

In order to cool the cultivated container subjected to the heat sterilization treatment in the cooling chamber, an electric charge is greatly increased. Therefore, the cultivated container subjected to the heat sterilization treatment is cooled by showering of cooling water. Moreover, the method (henceforth a "water cooling method") which immerses the cultivation container heat-sterilized in the cold water in a water tank, and is cooled is employ | adopted.

As a cap for cultivation containers used during the cooling treatment of such cultivation containers, it prevents invasion of germs into the cultivation container while ensuring gas exchange between carbon dioxide gas generated in the cultivation container and external oxygen. In order to do so, a cap has been proposed in which a filter using urethane, paper, or the like is incorporated between the front lid portion and the back lid portion (see, for example, Patent Document 1).

In addition, the problem of increased costs associated with the increase in the number of parts and assembly man-hours due to the addition of such a filter is solved, and the disadvantage of clogging of the gas exchange vents due to the entry and adhesion of mycelia into the filter In order to solve this problem, a cap for a mushroom cultivation bottle related to a structure such as a ventilation path has been proposed (see, for example, Patent Document 2).

The caps attached to such conventional mushroom cultivation containers are all related to improvements in securing gas exchange between carbon dioxide gas generated in the cultivation container and external oxygen, and the inside of the cap Concerning structure. All the surface portions of the cap are flat circular bodies.

FIG. 3 shows a configuration example of a conventional cap. As shown to a figure, it is comprised by the front side cover part 52 which covers the cap upper surface, and the back side cover part 51 which covers the opening part of the cultivation container 40, and ventilation for taking in external air in a cultivation container in the back side cover part 51 A hole 22 is provided. The shape of the upper surface (front side cover part) 55 of such a cap is a flat circular shape, and the outer peripheral end part 56 of the front side cover part is not formed with a peripheral part depending on the inner side of the end part. A protrusion 57 for fitting the front-side lid 52 into the back-side lid 51 is formed facing downward on the inner periphery.

When such a conventional cap is used to cool the cultivation container 40 by flowing shower-like water from above the cap as a cooling process for the cultivation container, water is introduced into the cap from the joint portion a between the front lid portion 52 and the back lid portion 51. However, there was a problem that the water that entered the cap entered the cultivation container and the amount of moisture and humidity of the medium changed, causing mushrooms to grow poorly. Further, while such a conventional cap is used for a long period of time, the front cover portion 52 of the cap may be warped, so that a gap is generated in the joint portion a, and water can easily enter the cap. .

In addition, since the shape of the upper surface 55 of the front lid portion 52 of the conventional cap is a flat circular shape, shower water that falls from above the cap can be used when used in a situation where the cap is not kept completely horizontal. There is also a problem that the cooling water does not flow uniformly on the surface of the cultivation container and the cooling efficiency of the cultivation container is lowered. In general, since the cultivation container is used by being stacked in a plurality of stages in the container, it is difficult to keep the cap horizontal, and this problem always occurs.

Furthermore, since the upper surface 55 of the front lid portion 52 of the conventional cap is flat or warped, water has accumulated on the upper surface 55 of the front lid portion 52 after the cooling process is completed and the cooling shower is stopped. Accumulated water leads to deterioration of the inoculation device, and also impairs the cleanliness of the inoculation room. Such a problem also occurs in the cooling process by the water cooling method. That is, water generated by condensation or the like from the bottom of the cultivation container or the container that accommodates it accumulates on the upper surface of the cap of the cultivation container accommodated in the lower stage of the container, leading to the propagation of germs.

The present invention has been made in view of the above circumstances, prevents intrusion of cooling water falling from above into the cultivation container, and evenly flows the cooling water to the surface of the cultivation container to increase the cooling efficiency of the cultivation container. An object of the present invention is to provide a cap for a mushroom cultivation container that can prevent water from accumulating on the cap surface.

An object of the present invention is a cap 10 for a mushroom culture container provided with a vent for performing gas exchange between at least carbon dioxide generated in a cultivation container and external oxygen, and is semicircular in a upward direction. This is solved by a cap for a culture vessel comprising a surface portion 11 that forms a bulge of and a peripheral edge portion 12 that hangs down from the outer peripheral end of the surface portion. The bulge of the surface portion 11 is preferably about 1 to 2 mm in height considering that several stages of cultivation containers are stacked.

Another object of the present invention is to form a corrugated protrusion 13 at the lower end of the peripheral edge 12 according to the present invention, and to form a plurality of ribs 14 that protrude perpendicularly to the upper surface of the surface 11 that forms the bulge. Or by forming a plurality of grooves 15 radially from the apex on the upper surface of the surface portion 11. The height of the rib 14 is approximately the same as the height of the bulge of the surface portion 11. Moreover, the some groove | channel 16 connected with each groove | channel 15 formed in the said surface part 11 can be formed in the surrounding surface of the said peripheral part 12 which concerns on this invention. The shape of the grooves 15 and 16 may be a corrugated pattern in which a continuous pattern of irregularities is formed.

Further, the object of the present invention is further advantageously solved by forming the cap of the present invention integrally and using a soft plastic such as polypropylene as the material.

And the cap which concerns on this invention is applied also to the cover body for cultivation containers of the double structure of a front side cover part and a back side cover part as shown in FIG. 2, FIG. In this case, the cap according to the present invention constitutes the front side lid. A back side cover part is equipped with the ventilation hole for fitting the inside of the surface part 11 and the peripheral part 12 of this cap 10, and performing the gas exchange with the carbon dioxide gas and external oxygen which generate | occur | produce in the container for cultivation at least. What is necessary is just to have, and the thing etc. which were equipped with the filter between the front side cover part and the back side cover part may be sufficient, and the structure etc. may be what as long as the cap of this invention fits.

In addition, when the cap of the present invention has a single structure that does not include a back side lid portion, for example, an engaging claw that abuts the neck portion of the cultivation container facing inward is formed at the lower end of the peripheral edge portion 12 to A vent hole for performing gas exchange is formed at intervals, and a protrusion is formed at an appropriate interval portion that abuts the opening edge of the cultivation container on the back surface of the front surface portion 11 to form a vent hole at the interval between the protrusion portions. It can be configured.

In the present invention, since a semi-disc-shaped bulge is formed on the cap surface portion upward, water does not collect on the cap surface, and a peripheral portion depending from the outer peripheral end of the surface portion is formed. The cooling water from the inside does not enter the cap and the cultivation container.

In the present invention, the corrugated protrusion 13 is formed at the lower end of the peripheral portion, the plurality of ribs 14 are formed on the upper surface of the surface portion, or the plurality of grooves 15 are formed radially from the apex on the upper surface of the surface portion. Further, since the plurality of grooves 16 communicating with the grooves formed in the surface portion are formed on the peripheral surface of the peripheral portion, the cooling water showered from above is uniformly flowed to the surface of the cultivation container. Thus, the cooling efficiency of the cultivation container can be increased. In addition, by integrally molding the cap according to the present invention, the manufacturing cost can be reduced, and by making the material a soft plastic such as polypropylene, the cultivation container, the back lid portion can be easily engaged, fitted and removed. be able to.

According to the present invention, water does not accumulate on the cap surface, and cooling water from above can be prevented from entering the cultivation container through the cap. The cooling water showered from above can be made to flow uniformly over the surface of the cultivation container to increase the cooling efficiency of the cultivation container. Therefore, it is possible to maintain an appropriate amount of moisture and humidity of the culture medium in the cultivation container, and it is possible to prevent the growth failure of mushrooms and the propagation of various germs, and it is possible to shorten the cooling time of the cultivation container and to perform the cooling process. Enables cost reduction.

The present invention will be specifically disclosed below. FIG. 1 is a perspective view showing a schematic appearance of a cap for a culture container for mushrooms according to the present invention. As shown in the figure, the present invention is composed of a surface portion 11 formed with a semi-disc-shaped bulge upward and a peripheral edge portion 12 depending from an outer peripheral end portion of the surface portion. A wave-shaped protrusion 13 is formed, and a plurality of ribs 14 projecting vertically with the same height as the bulge are formed on the upper surface of the surface portion 11, and the upper surface of the surface portion 11 is radial from the apex to the periphery. A plurality of grooves 15 are formed, and a plurality of grooves 16 communicating with the grooves 15 formed in the surface portion 11 are formed on the peripheral surface of the peripheral edge portion 12.

The surface portion 11 having a semi-disc-shaped bulge upwards quickly drains downward without accumulating shower water and water drops falling from above. The peripheral part 12 is integrally molded by the same member as the surface part 11 and covers the whole opening part of the cultivation container 40 or accommodates the back side cover parts 31 and 51 inside thereof. The corrugated protrusion 13 is formed at the lower end of the peripheral edge 12 and allows water flowing down from the surface portion 11 to flow downward uniformly without concentrating from the tip of the corrugated protrusion.

The rib 14 is formed on the surface portion 11 where the bulge is formed, and uniformly disperses water falling from above on the surface portion 11. Although the case where six ribs 14 are formed is shown here, the number of ribs can be arbitrarily selected. Further, grooves 15 and 16 are formed in the surface portion 11 or the peripheral portion 12 thereof. It is desirable that the groove 15 of the surface portion 11 and the groove 16 of the peripheral edge portion 12 communicate with each other. When the ribs 14 are not formed on the surface portion, these grooves suppress the concentration of the flow path of water that falls from the surface portion 11 via the peripheral edge portion 12 to one place, and the water falls as a whole. It is what I did. The shape of the groove may be a V-shaped notch, but may be a rounded unevenness or a continuous waveform pattern.

In consideration of mass production and manufacturing costs, it is convenient to integrally form the cap of the present invention, and in consideration of the engagement, fitting and detachment processing with the cultivation container and the back cover, the cap of the present invention The material is advantageously a soft plastic such as polypropylene.

FIG. 2 is a schematic sectional side view of a culture container cap for mushrooms according to the present invention, FIG. A shows a state in which the cap according to the present invention is provided with a back side lid 31 inside, and FIG. The state which removed the cap from the back side cover part 31 is shown. Here, the cap 10 which concerns on this invention comprises the front side cover part, and has shown the structure provided with the back side cover part 31 fitted inside the surface part 11 and the peripheral part 12 of this cap. Outside air A is introduced into the cap from the ventilation space between the peripheral edge portion 12 and the back lid portion 31 through the ventilation hole 22. Gas exchange is performed between the carbon dioxide gas generated in the cultivation container 40 and the oxygen in the outside air A through the vent hole 23. That is, oxygen is supplied from the outside air A to the cultivation container through the vent hole 23, and carbon dioxide gas generated by the activity of mushroom mycelia is discharged from the cultivation container to the outside.

Here, a filter is not attached between the front lid portion and the back lid portion 31 constituting the present invention, but the back lid portion mounted inside the present invention is provided with a filter or shown here. However, the present invention relates to the form of the front cover, and the structure of the back cover applied to the present invention may be anything. It is not particularly limited.

Next, the operation and operation of the cap of the present invention will be described with reference to FIGS. Shower-like cooling water W or water-drop-like cooling water W whose temperature is controlled falls from above the cap 10 onto the surface portion 11 of the cap. Since the surface portion 11 is raised in a dome shape toward the apex, the shower-like or water-drop-like cooling water W falling on the cap 10 is quickly removed downward without staying there. For this reason, it is possible to prevent harmful effects caused by water accumulated on the cap surface.

Moreover, the shower-like cooling water W that has fallen on the surface portion 11 is divided into six by the ribs 14 formed on the surface portion 11 and flows down toward the peripheral edge portion 12. Since the cooling water W is equally divided into six parts, the amount of the cooling water W flowing from the surface portion 11 to the surface of the cultivation container 40 is uniform here. Then, the cooling water W that has flowed down the surface portion flows down from the tip of the corrugated protrusion 13 along the surface of the peripheral portion. Since the corrugated protrusions 13 are formed at equal intervals at the tip of the peripheral edge portion 12, the cooling water W flows down more evenly with respect to the surface of the cultivation container 40.

Further, as shown in FIG. 1, grooves 15 and 16 are formed in the surface portion 11 and the peripheral portion 12. Therefore, the cooling water W that has fallen on the surface portion 11 flows along the grooves 15 and 16 from the surface portion toward the peripheral portion, and more uniformly flows on the surface of the cultivation container 40. The cooling water W flowing down in this way cools the surface of the cultivation container 40 and efficiently cools the medium contained therein.

In addition, as shown in FIG. 2, the cap according to the present invention has the peripheral edge portion 12 integrally formed of the same member as the surface portion 11, covers the entire opening of the cultivation container 40, and the back side lid portion 31 is In order to be accommodated inside, the cap according to the present invention has a structure in which the opening or the back side lid of the cultivation container is covered like an umbrella. That is, it plays the role of the umbrella of the opening part of a cultivation container and a back side cover part. Therefore, the cooling water W does not enter the inside of the cultivation container and the inside of the back cover part.

According to the present invention, water does not accumulate on the cap surface, and cooling water from above can be prevented from entering the cultivation container through the cap. Since the cooling efficiency of the cultivation container can be increased by flowing shower-like cooling water over the surface of the cultivation container, in the cooling treatment by showering after the heat sterilization treatment, this poor growth that can be cultivated can be prevented. Therefore, the cooling time can be shortened and the cooling efficiency can be increased to greatly reduce the cost. Moreover, the same effect can be acquired also in a water cooling system. Therefore, it is possible to efficiently cool the cultivation container and shift to a culture process in an environment suitable for mushroom cultivation, and the present invention can be expected to contribute to the cultivation of mushrooms.
