Cap assembly for mushroom cultivation bottle

A cap assembly for a cultivation bottle for mushrooms, the cap assembly comprising:

• a bottle fitting member comprising:
• a large-diameter hollow cylindrical part configured to cover an outer periphery of a mouth part of the cultivation bottle;
• a small-diameter hollow cylindrical part positioned above and concentrically with the large-diameter hollow cylindrical part and having an inner diameter smaller than an inner diameter of the large-diameter hollow cylindrical part;
• and
• a connecting part that extends laterally and connects the large-diameter hollow cylindrical part with the small-diameter hollow cylindrical part;
• and
• a bowl-shaped member comprising:
• a base portion at a first end;
• an upper edge at an opposite second end;
• a bowl-shaped portion rising upward from the base portion to the upper edge, the bowl-shaped portion having an arcuate inner surface;
• and
• an internal hollow cylindrical portion positioned within the bowl-shaped portion on the base portion and projecting upwardly beyond at least a portion of the arcuate inner surface towards the upper edge;
• wherein the internal hollow cylindrical portion of the bowl-shaped member has an inner diameter that corresponds to the inner diameter of the small-diameter hollow cylindrical part of the bottle fitting member and is configured to elongate a hard tip portion of mushroom fruiting bodies growing in the cultivation bottle and up through the cap assembly;
• and
• wherein the bowl-shaped member is configured to be separable from the bottle fitting member to facilitate harvesting of the mushroom fruiting bodies and removal of a section of the elongated hard tip portion.

A method of growing and harvesting mushrooms in a cultivation bottle using a cap assembly, comprising:

• mounting a cap assembly on a mouth part of the cultivation bottle for growing mushrooms;
• growing the mushrooms from inside the cultivation bottle and up through the cap assembly;
• harvesting the mushrooms after growth of the mushrooms has ended;
• and
• cutting off a hard tip part of a harvested mushroom at a midsection location, wherein the cap assembly comprises:
• a bottle fitting member configured to fit onto the mouth part of the cultivation bottle, and
• a bowl-shaped member configured to be placed on the bottle fitting member, wherein the bowl-shaped member comprises:
• a base portion at a first end;
• an upper edge at an opposite second end;
• a bowl-shaped portion rising upward from the base portion to the upper edge, the bowl-shaped portion having an arcuate inner surface;
• and
• an internal hollow cylindrical portion positioned within the bowl-shaped portion on the base portion and projecting upwardly beyond at least a portion of the arcuate inner surface towards the upper edge;
• wherein the internal hollow cylindrical portion corresponds to the bottle fitting member and is configured to increase the height of the bottle fitting member above the mouth part of the cultivation bottle, to thereby elongate a hard tip portion of mushroom fruiting bodies growing in the cultivation bottle and up through the cap assembly.
