Abstract: A collapsible container having a generally cylindrical configuration including at least an upper thicker section and a lower thicker section, and at least one thinner section positioned between the upper and lower thicker sections. When the container is collapsed, the upper and lower thicker sections are telescoped within one another and the thinner section is folded therebetween. The container is made of a monolayer of a thermoplastic polymer having a flex modulus of from 60,000 to 160,000 psi and a heat distortion temperature at 66 psi of greater than 170 degrees F. A process for making the collapsible container using extrusion blow molding is also disclosed.
