Abstract
The present disclosure relates to an integrated liner-based system having an overpack and a liner provided within the overpack, the liner comprising a mouth and a liner wall forming an interior cavity of the liner and having a thickness such that the liner is substantially self-supporting in an expanded state, but is collapsible at a pressure of less than about 20 psi. The liner and overpack may be made by blow molding the liner and the overpack at the same time using nested preforms.

A liner-based system comprising:
- an overpack;
- and
- a liner provided within the overpack, the liner comprising a mouth and a liner wall defining an interior cavity of the liner, the liner including a top portion and a bottom portion separated by a non-sloping portion, the liner defining a plurality of vertically disposed grooves and a plurality of horizontally disposed grooves along a circumference of the non-sloping portion of the liner, wherein the overpack includes a top portion and a bottom portion separated by a non-sloping portion, the overpack defining a plurality of vertically disposed grooves and a plurality of horizontally disposed grooves along a circumference of the non-sloping portion of the overpack, the plurality of vertically disposed grooves of the overpack being co-extensive with the plurality of vertically disposed grooves of the liner, and the plurality of horizontally disposed grooves of the overpack being co-extensive with the plurality of horizontally disposed grooves of the liner.
