Apparatus for mounting a liner comprising a liner discharge component to a container

A method for mounting an adapter to a discharge nipple of a container comprising a rigid outer wall, a top surface, and a bottom surface defining a cavity, the method comprising:

• mounting a nipple adapter to the discharge nipple of the container, wherein the nipple adapter comprises a nipple adapter body having a nipple adapter input opening, a nipple adapter output opening and a nipple adapter central lumen extending therebetween, and wherein the nipple adapter body comprises a nipple adapter seat;
• disposing a liner discharge fitment comprising a discharge fitment input opening, a discharge fitment output opening and a passageway extending therethrough in the discharge nipple of the container such that a radially extending flange extending about a perimeter of the discharge fitment output opening is disposed against the nipple adapter seat;
• and
• mounting an elbow adapter comprising an elbow adapter input opening, an elbow adapter output opening and an elbow adapter passageway extending therebetween to the nipple adapter, wherein the elbow adapter body comprises an elbow adapter seat for engaging the flange of the liner discharge fitment against the nipple adapter seat.

A discharge element for selectively discharging the contents of a container comprising an outer wall, a top surface, and a bottom surface defining a cavity, the container further comprising an outlet formed in the bottom surface and fluidically connected to the cavity, the discharge element comprising:

• a nipple adapter comprising a nipple adapter body having a nipple adapter input opening, a nipple adapter output opening and a nipple adapter central lumen extending therebetween, and further wherein the nipple adapter body comprises a nipple adapter seat;
• and
• an elbow adapter comprising an elbow adapter body having an elbow adapter input opening, an elbow adapter output opening and an elbow adapter passageway extending therebetween, wherein the elbow adapter body comprises an elbow adapter seat;
• a discharge fitment configured to be received in the nipple adapter central lumen, the discharge fitment comprising an inlet, an outlet, and a neck portion having a passageway extending therethrough, the neck portion extending through the nipple adapter central lumen and terminating at the outlet in a radially-extending outlet flange;
• wherein the flange of the discharge fitment is configured to be seated against (i) the nipple adapter seat, and (ii) the elbow adapter seat, whereby to form a fluidic seal between the nipple adapter output opening and the elbow adapter input opening.
