International Classification:
B65D 8800
US Classification:
141 8, 141 5, 141 18, 141 86, 220565, 22056011, 22056004, 220 15, 220 861, 280830, 137376, 137592
Abstract:
A container for holding a solid, liquid and/or gaseous phase product therein and for use within a transportable or stationary support structure. The container maximizes the compressed product volume contained therein and prevents liquid and/or contaminant entrainment during gaseous product delivery from liquid phase product. The system allows for product withdraw when the level is above the delivery valves using, at a minimum, two delivery legs linked by a compartment or housing that connects the delivery point and a container head space via a removable manway.

International Classification:
B08B005/00
US Classification:
137 1504, 137574, 134 2218, 220563
Abstract:
A vessel for the storage and transportation of bulk volumes of a fluid is described herein and a method for using same. The vessel contains a plurality of dividers that apportion the internal volume into a number of sections. The dividers within the vessel aid in minimizing sloshing of the fluid contained therein during transport. In addition, the dividers optimize the fluid flow pattern thereby allowing for the continuous purge of the vessel without the need for the application of a partial or full vacuum.
