Corrugated storage container

A container for the transport and storage of bulk material, the container comprising:

• an upper box section having an upper interior volume, the upper box section including first and second corrugated side walls, first and second corrugated end walls, and a top wall having an inlet formed therein;
• a lower funnel section having a lower interior volume disposed at a bottom of the upper box section opposite the top wall and terminating at an outlet, the lower funnel section including first and second side plates extending downwardly and inwardly from the first and second side walls, respectively, first and second end plates extending downwardly and inwardly from the first and second end walls, respectively, and a radiused corner section joining each of the first and second side plates with each of the first and second end plates;
• a vertical post disposed between adjacent side walls and end walls to form corners therebetween, wherein each vertical post has an L-shaped cross section having a first flange joining a side wall and a second flange joining an end wall such that the vertical posts are integrated into the upper box section;
• a plug plate located in each of the vertical posts, each plug plate having an upper region disposed within the vertical post and a lower region extending from the vertical post at an angle relative to the vertical post, the lower region having a curved cut-out portion,
• wherein each plug plate is formed to provide a downward transition between the upper box section and the lower funnel section for directing bulk material stored in the vertical post down into the lower funnel section;
• and
• a frame configured to support the upper box section and the lower funnel section, the frame including a first set of cross beams extending between an upper end of adjacent vertical posts, a second set of cross beams extending between adjacent vertical posts at the bottom of the upper box section, a third set of cross beams extending between the lower end of adjacent vertical posts, and an angular gusset located beneath each of the first and second side plates and each of the first and second end plates, wherein the angular gussets extend outwardly from the third set of cross beams to support the funnel section;
• and
• wherein the upper interior volume and the lower interior volume define a container storage volume for receiving bulk material through the inlet and discharging bulk material through the outlet.
