Description

[Detailed description of the invention] (Field of industrial application) This invention belongs to the field of mushroom cultivation, and is used as a lid for a cultivation bottle that facilitates humidity and ventilation adjustment during mushroom cultivation.

(Prior Art) A filter is used in the lid of a mushroom cultivation bottle to prevent germs and to control humidity and ventilation. Generally, the filter is used by being fitted into a recess provided vertically on the top surface of the lid. When this lid is used on a cultivation bottle and culture begins in the culture room, the surface of the filter fitted in the recess is exposed to the atmosphere, so air and moisture that have passed through the filter are supplied to the culture medium, and conversely, air and moisture are supplied to the culture medium. Exhaust gas is exhausted to the outside through a filter. However, in a culture room, the vapor density is high, so water droplets generated on shelves, etc., fall onto the filters along with dirt and other particles. The water droplets pass through the filter and provide more water than necessary to the culture medium, causing the growth of bacteria and impeding the growth of mushrooms. For this purpose, many cultivation bottles are covered with sheets to prevent water droplets, but this poses problems such as steaming inside the bottles and deteriorating the cultivation environment.

(Problem that the invention aims to solve) In the conventional cultivation bottle lid mentioned above, a part of the filter is exposed to the outside air, so the filter is covered with an umbrella-shaped lid to prevent direct contact with water droplets, etc. The idea is to drain water droplets to the outside, and also to make it possible to adjust the amount of ventilation using an umbrella-shaped lid.

(Means for solving the problem) The bottom edge of the disk body has a ring leg that fits over the mouth of the cultivation bottle, the upper edge has a brim of the required thickness, and the center part has a large ring. A ring wall is provided on the periphery of the hole as a hole so as to protrude above and below the disk body. The height of the upper part of the ring wall is lower than the edge of the brim, and the upper wall has large grooves diagonally cut out, and a small hole is bored in the middle of each groove, and a hole is bored in the bottom of the lower part. It is covered with a bottom plate. At the boundary between the ring wall and the surface of the disk body, a groove is dug into which the peripheral wall of the umbrella disk described below will fit, and the surface of the disk body is sloped downward from the upper edge of the groove toward the brim edge to drain water to the brim edge. A hole is drilled for the purpose. The umbrella plate is made by installing a peripheral wall vertically around the bottom edge of the top plate, drilling grooves and holes in the same wall in the same phase as the grooves and holes in the ring wall, inserting a filter into the ring wall, and forming the umbrella plate. This purpose is achieved by selecting the height of the umbrella board so that the top plate of the umbrella board and the upper surface of the brim are on the same horizontal plane when fitted to the ring wall.

(Function) Water that drips or condenses on the top of the umbrella disc flows down to the disc body and is drained from the holes in the brim edge. By rotating the canopy disc and overlapping its grooves and holes with the same grooves and holes in the ring wall of the disc body, the amount of ventilation can be increased, and by overlapping the grooves in the canopy disc with the holes in the ring wall, the holes in the canopy disc and the grooves in the ring wall can be increased. Since the holes also overlap, the amount of ventilation is suppressed to a small level by the holes. Since the upper surface of the brim and the top surface of the umbrella board are on the same horizontal plane, it is stable even when the cultivation bottles are stacked.

(Example) To explain an example of this invention, a disc body 1 of the lid body made of synthetic resin has a ring leg 2 of a required depth hanging from the bottom periphery to fit over the mouth of a cultivation bottle. The peripheral edge of the surface is a flange edge 3 having a thickness that makes it easy to handle the lid body, and a ring wall 4 is provided on the inner peripheral edge of a large hole bored in the center to protrude above and below the disk body 1. The ring wall 4 has an upper height lower than the height of the collar edge 3, a lower depth shallower than the ring leg 2, and a groove 5 with a large depth and width diagonally in the upper wall. A small hole 6 is bored in the middle of each groove 5, and a bottom plate 8 with a hole 7 in the center of the lower bottom surface closes the groove. At the boundary between the ring wall 4 and the surface of the disk body 1, there is a groove 10 into which the lower part of the peripheral wall of the umbrella disk 9 described below is fitted.
The surface of the disc body 1 is sloped downward from the upper edge of the groove 10 toward the collar edge 3, and a hole 1 is formed in the collar edge 3.
I'm wearing 1. The umbrella board 9 has a peripheral wall 1 on the bottom edge of the top board.
2 is vertically installed at a height close to the height from the bottom of the groove 10 to the top of the ring wall 4, and the groove 5 and the hole 6 in the ring wall 4 are provided with holes of the same size and in the same phase. It has a groove 5' and a hole 6', and a synthetic resin filter 13 is fitted into the ring wall 4, and an umbrella plate 9 is fitted thereon, and the ring wall 4 is used by fitting it into a cultivation bottle.

(Effects of the invention) Excess moisture does not enter the culture medium of the cultivation bottle, and the amount of ventilation can be adjusted freely, which has the effect of increasing cultivation efficiency.
