Abstract
A syrup container system for post-mix beverage dispensing systems comprising filling a blow molded, multi-layer PET container with syrup and connecting the container to a post-mix beverage dispenser through a syrup pump. The PET container includes a release agent such as a layer of EVOH located outside of the inner PET layer and an air vent partway through the container wall terminating at the inner PET layer or at the adjacent release layer, so that the inner PET layer can separate from the remainder of the wall and collapse around the remaining syrup as it is withdrawn, without the need for venting the syrup chamber to atmosphere. The PET container also includes a polyethylene closure sealing the container opening and coupling means for connecting to a quick-disconnect coupling on the distal end of a syrup line. The PET container is disposable and recyclable.
