ABSTRACT:
A tubular article, such as a plastic bottle, of optionally stepped cross-sections, with one section next to one of the steps incorporating near vertical tucks permits collapsing of the article. Under an axial force, the bottle or article will collapse in a telescoping manner by inverting inside for outside of the section with the tucks. The invention of the tucks stretch or expand them which increases the area enclosed by the cross-section and thereby allows the telescoping in a pre-determined manner. Reversing the axial force will cause the collapsed container to extend or expand.
