Stackable bulk fluid storage container

A stackable bulk fluid storage container comprising:

• a frame assembly including a lower frame member having longitudinal rails and an upper frame member having longitudinal guides, wherein the lower frame member is arranged in spaced relation to the upper frame member by a plurality of vertically extending posts;
• a fluid storage vessel for storing a fluid including:
• first and second end walls held in spaced relation by first and second side walls, a top wall and a bottom wall which defines a sealed fluid storage volume;
• a baffle assembly including a plurality of baffle plates disposed in a space relationship in the fluid storage volume;
• a fill port disposed in an upper region of the fluid storage vessel and in fluid communication with the fluid storage volume for filling the fluid storage volume;
• a first port formed through one of the first and second end walls in an upper region of the fluid storage vessel and in fluid communication with the fluid storage volume for venting the fluid storage volume to maintain an atmospheric pressure therein;
• and
• a second port formed through one of the first and second end walls in a lower region of the fluid storage vessel and in fluid communication with the fluid storage volume for draining the fluid storage volume;
• a height of the first end wall that is less than a height of the second end wall, and the fluid storage vessel further comprises a ramped section extending from the top of the first end wall to the top wall configured to facilitate loading and stacking of a second bulk fluid storage container onto the bulk storage container in a vertically stacked relationship;
• wherein the frame assembly provides an exoskeletal structure surrounding the fluid storage vessel and is configured to support a second bulk fluid storage container in the vertically stacked relationship.

A stackable bulk fluid storage system comprising:

• first and second bulk fluid storage containers, each of the first and second bulk fluid storage containers comprising:
• a fluid storage vessel defining a fluid storage volume for storing a fluid, the fluid storage vessel includes a top port formed in the fluid storage vessel for filling the fluid storage volume, one or more upper ports formed in the fluid storage vessel for venting the fluid storage volume to maintain an atmospheric pressure therein and one or more lower ports formed in the fluid storage vessel for draining the fluid storage volume;
• and
• a frame assembly surrounding the fluid storage vessel to provide an exoskeletal structure, the frame assembly having a lower frame member including longitudinal rails arranged below the fluid storage vessel, an upper frame member having longitudinal guides arranged above the fluid storage vessel and a plurality of posts circumscribing the fluid storage vessel and extending between the lower frame member and the upper frame member, wherein the frame assembly of at least the first bulk storage container comprises a ramped section in a front-end region extending from a front end wall to a perpendicular top wall configured to facilitate loading and stacking of the second bulk fluid storage container onto the first bulk storage container in a vertically stacked relationship, wherein the frame assembly is an integral part of the bulk fluid storage container;
• wherein the first bulk fluid storage container supports the second bulk fluid storage container in the vertically stacked relationship and the longitudinal guides on the first bulk fluid storage container cooperate with the longitudinal rails on the second bulk fluid storage container for aligning the first and second bulk fluid storage containers in the vertically stacked relationship.
