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.
Claims17
A liner-based system comprising:
- a collapsible liner disposed within an overpack configured to dispense a fluid contained within the collapsible liner by collapsing the collapsible liner, wherein the liner and overpack are made by blow molding the liner and the overpack at the same time using nested preforms, the collapsible liner and the overpack being comprised of different materials having different melting points,
- wherein the liner has a thickness such that the liner is substantially self-supporting in an expanded state, and
- wherein the collapsible liner defines surface features configured to be predisposed against collapsing of the collapsible liner when not in active dispense, the surface features of the collapsible liner defining a plurality of vertically disposed grooves and a plurality of horizontally disposed grooves along a circumference of the collapsible liner,
- wherein the plurality of vertically disposed grooves of the collapsible liner and the plurality of horizontally disposed grooves of the collapsible liner outline a plurality of rectangular-shaped panels spaced around the circumference of the collapsible liner.
An integrated liner-based system comprising:
- an overpack;
- and
- a collapsible liner provided within the overpack, the collapsible liner comprising a mouth and a liner wall forming an interior cavity of the collapsible 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;
- wherein the liner and overpack are made by blow molding the liner and the overpack at the same time using nested preforms;
- and
- wherein the collapsible liner defines surface features configured to be predisposed against collapsing of the collapsible liner when not in active dispense, the surface features of the collapsible liner defining a plurality of vertically disposed grooves and a plurality of horizontally disposed grooves along a circumference of the collapsible liner,
- wherein the plurality of vertically disposed grooves of the collapsible liner and the plurality of horizontally disposed grooves of the collapsible liner outline a plurality of rectangular-shaped panels spaced around the circumference of the collapsible liner.
