Abstract
A liner for use with a fluid dispensing vessel. The liner includes a flexible pouch defining an interior region and configured to be placed in a fluid dispensing vessel. The pouch includes a top end that is partially sealed and that includes a first opening. The pouch includes a fluid passageway defined by at least two sealed boundaries and that leads from the opening to the interior region. The pouch includes a bottom end that includes a second opening. The liner includes a fluid dispensing fitment connected to the pouch and configured to be in fluid communication with interior region via the second opening. When fluid is poured into the interior region of the pouch through the opening, it can be dispensed from the pouch through the fitment.

A liner for use with a fluid dispensing vessel, comprising:
- a flexible pouch having a top end, a bottom end, and first and second sides that define an interior region, the pouch being configured to be placed in a fluid dispensing vessel;
- a top region of the pouch including:
- a first seal that defines the top end,
- a perforation located below the first seal, that is generally parallel to the first seal,
- and that extends from the first side across a portion of the width of the pouch;
- and
- a second seal that is located between the perforation and the second side of the pouch;
- wherein a portion of the top region can be torn from the pouch along the perforation from the first side toward the second side but not beyond the second seal to create a tear strip and to create a top opening in the pouch that leads to the interior region, wherein the second seal connects the tear strip to the pouch and wherein the tear strip can be used to tie up the pouch to close off the top opening;
- a bottom region of the pouch that includes a bottom opening;
- a fluid dispensing fitment connected to the pouch and configured to be in fluid communication with the interior region via the bottom opening;
- and
- wherein fluid is poured into the interior region of the pouch through the top opening, the top opening is closed off with the tear strip, and liquid is dispensed from the pouch through the fitment.

A liner for use with a fluid dispensing vessel, comprising:
- a flexible pouch having a top opening, a sealed bottom region, and a front panel, a rear panel, a first side panel, and a second side panel that define an interior region, wherein the front, rear, and first and second side panels each include a triangular bottom portion, and the first and second side panels are folded inward to have gussets, and
- a fluid dispensing fitment connected to the pouch and configured to be in fluid communication with the interior region,
- wherein, when the pouch is filled with fluid through the top opening, the gussets unfold and the triangular bottom portions fold such that the bottom region becomes generally flat along a bottom end and has a generally quadrilaterally shaped footprint and liquid is dispensed from the pouch through the fitment.
A method of making a gusseted liner for use with a beverage dispensing vessel, comprising:
- forming a tube of plastic film;
- folding the tube to have a front panel, a rear panel, a first folded side panel extending between the front and rear panels, and a second folded side panel extending between the front and rear panels;
- slitting the tube to separate the front panel from the first and second side panels;
- forming a hole in the front panel;
- connecting a fluid dispensing fitment to the front panel such that the fitment is in fluid communication with the hole;
- sealing an inner side of the front panel to top inner sides of the first and second folded side panels with side seals;
- sealing the inner side of the front panel to the top inner sides of the folded first and second side panels with first bottom seals;
- sealing an inner side of the rear panel to bottom inner sides of the first and second folded side panels with second bottom seals;
- trimming excess film located beneath the first and second bottom seals to define triangular shaped bottom ends of the front panel, rear panel, and first and second side panels;
- and
- trimming film located at the top of the tube to define a top end of the liner.
