Abstract
A paper container has a bottom in which there is impressed a deformation groove to allow the bottom to deform in response to reduced internal pressures occurring as a hot liquid cools inside of the closed container. The bottom is formed in a continuous one-step process in which a series of coaxially arranged, telescoping tools travel relative to one another along a common axis to form the bottom with the deformation groove and a bent outer edge.
