ABSTRACT:
Liquid storage tank containing a collapsible bag of flexible impervious sheet material supported by a collar within the tank which floats on the stored liquid and moves with the liquid thereby dividing the interior of the shell into an air and a liquid space. The bag has an external skirt of a similar flexible sheet material attached to the supporting collar which lies between the bag and adjacent tank side walls to reduce abrasion and catching of the bag and tank walls particularly during tank emptying and filling procedures.
