Abstract
A container having panels that contain a bag of strip material. The container is movable between a confining position enclosing the bag of strip material and a position in which the bag is relaxed so as to relax snags of looped elastic material that may have arisen during transit. During transit, the strip material has a tendency to flow from the top and over the edges of the bulk to work its way along the sides, potentially snagging with adjacent loop material. During dispensement of the strip material, these snags may give rise to tension spikes. By displacing the panels of the container out of the confining position and into a relaxed position, the confining forces become relieved and thereby the snags relax. The tension spikes otherwise arising during dispensement are thereby eliminated.
