An object of the present invention has a high air-tightness, for example, water and molasses to feed rice, and adding a lactic acid bacteria suitable for carrying out the anaerobic fermentation by, flexible container securely perform movement after the packing and the packing by bag, and an object thereof is to provide a silo, and the silo system. A This silo 1 has a hollow container body 4 at the upper opening, the fitting portion 2 including a predetermined protruding shape that is integrally molded on the upper edge portion of the container body 4 in a portion thereof and has a protruding portion 3 which protrudes so as to be larger inner diameter than the side face of the container body, a locking portion 6 which is recessed towards the inside so as to be smaller than the inner diameter side of the container body, the top of the container body 4 In the bottom, the bottom 8 has a side surface which is recessed towards the inside so that the side face than the smaller inner diameter of the container body 4, at least one of the inside air and moisture in the container main body provided on the lower side of the container body 4 and a lower discharge section 9 for discharging to the outside.BACKGROUND 1【課題】高い気密性を有し、例えば飼料用米に水分や糖蜜、乳酸菌を添加して嫌気性発酵を行うのに好適で、フレコンバッグによる梱包並びに梱包後の移動を確実に行える、サイロ、及びサイロシステムを提供することを目的とする。【解決手段】このサイロ1は、上部開口で中空の容器本体4と、容器本体4の上端縁部分に一体成型された所定の突出形状を含む嵌合部2をその一部に有し、上記容器本体の側面より大きな内径となるように突出した突出部3と、容器本体の側面より小さい内径となるように内部に向けて凹んだ係止部6と、容器本体4の最下部において、上記容器本体4の側面より小さい内径となるように内部に向けて凹んだ側面を有する底部8と、容器本体4の下方に設けられ上記容器本体の内部の空気と水分の少なくともいずれかを外部に排出するための下方排出部9とを備えている。【選択図】図1
