Abstract:
1. In combination: a) a container for a flowable material, the container having a peripheral wall bounding a storage space into which flowable material can be introduced and in which introduced flowable material can be confined, the storage space having a volume, the peripheral wall having a plurality of accordion folds that permit reconfiguring of the wall so as to thereby vary the volume of the storage space; and b) at least one restrictor assembly that in an operative position cooperates with the container to control reconfiguring of the peripheral wall by limiting expansion of the accordion folds, the restrictor assembly having a positively fixed length configuration, extending continuously around the outside of the container and in the operative position closely surrounding the container over substantially the entire fixed length of the restrictor assembly and exerting a force upon the container to control expansion of the accordion folds to a first state and thereby reconfiguring of the peripheral wall into one predetermined state wherein the storage space will accept a first predetermined maximum volume of flowable material, the restrictor assembly changeable from the operative position to another position wherein the restrictor assembly does not surround the container so as to limit expansion of the accordion folds, the accordion folds expandable from the first state into a second state with the at least one restrictor assembly in the another position wherein the peripheral wall is reconfigured to another predetermined state wherein the storage space will accept a second predetermined maximum volume of flowable material that is greater than the first predetermined volume of flowable material.
