<p>A collapsible container has a front face and a collapsible backing, wherein the container volume decreases as product is removed, and the collapsible backing collapses by vacuum as the container volume decreases. The front face may be flexible and thus susceptible to losing its original shape as the container volume decreases, but is nevertheless designed to retain its shape by having a frame around at least a portion of its perimeter. The front face may instead be adapted to retain its shape as the collapsible backing collapses upon a decrease in the container volume. The collapsible container is of particular beneficial use in a dispenser housing having a sight window in a front wall thereof, the sight window being aligned with the front face of the collapsible container.</p> |
