The phenomenon will not occur.

  Since the vertical support bar 140 is fixed to the vertical fixing groove 111 and the horizontal support band 150 is fixed to the horizontal fixing groove 112, the vertical support bar 140 and the horizontal support band 150 are not out of position. The container body 110 is always firmly and securely fastened to support the container body 110.

  In addition, a vertical fixing groove 111 and a horizontal fixing groove 112 are formed in the container body 110, and several inward ribs 117 are formed on the upper surface of the container body 110. By forming 114 and 115, the overall strength of the container body 110 made by molding a synthetic resin material is increased.

  In addition, when the intermediate bulk container 100 according to the present invention is stacked up and down, as shown in FIGS. 4, 6, and 7, the upper cover 130 has a fitting protrusion 132 protruding upward and is fitted to the lower support 120. A groove 125 is formed, and the fitting protrusion 132 of the intermediate bulk container 100 positioned on the lower side is fitted into the fitting groove 125 of the intermediate bulk container 100 laminated on the upper side, and thus the layers are laminated vertically. Each intermediate bulk container 100 maintains a stable state without rolling or coming off.

  In addition, the intermediate bulk container 100 according to the present invention has forklift claw insertion grooves 124 formed on both lower sides of the lower support 120, so that the heavy intermediate bulk container 100 inside and outside 1 ton can be easily transferred.

  As shown in FIGS. 4 and 5, several support rod insertion grooves 127 are formed in the upper portion of the lower support base 120 in the horizontal direction, and the container main body 110 is formed in each support rod insertion groove 127. Since the bottom support rod 126 for supporting the lower portion of the container body 110 is provided, the lower support base 120 sufficiently supports the container body 110 in which heavy contents are accommodated, thereby providing a solid intermediate bulk container 100.
