Abstract
A method for supplying syrup to a post-mix beverage dispensor comprising filling a blow molded, multi-layer PET container with syrup and connecting the container to the post-mix beverage dispenser through a syrup pump. The PET container includes an outer PET layer and a delaminatable inner PET layer and at least one air vent partway through the container wall terminating at the inner PET layer, such that the inner PET layer can separate from the remainder of the wall and collapse around the remaining syrup as it is withdrawn, without the need for venting the syrup chamber to atmosphere.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.
