<p>The combination of a container for flowable material and at least one restrictor assembly. The container has a peripheral wall bounding a storage space into which flowable material can be introduced and in which flowable material can be confined. The storage space has a volume and is reconfigurable to thereby vary the volume. The at least one restrictor assembly cooperates with the container to control reconfiguring of the peripheral wall.</p> |
