Claims20
A container comprising:
- a top wall;
- a bottom wall opposite the top wall;
- and
- a side wall extending from the top wall to the bottom wall,
- wherein the bottom wall comprises a first portion extending transverse to the side wall and a second portion extending transverse to the first portion, the second portion being spaced apart from the side wall by the first portion,
- wherein the bottom wall comprises a shelf extending inwardly from the second portion, the shelf defining a panel configured to move outwardly and inwardly relative to the side wall through the shelf during pressure application, the panel comprising a center portion and a plurality of spaced apart radial segments disposed circumferentially about the center portion, the center portion being concave, at least one of the segments being tapered toward the center portion.

A container comprising:
- a top wall;
- a circumferential bottom wall opposite the top wall;
- and
- a side wall extending from the top wall to the bottom wall,
- wherein the bottom wall comprises a first portion extending transverse to the side wall and a second portion extending transverse to the first portion, the second portion being spaced apart from the side wall by the first portion,
- wherein the bottom wall comprises a shelf extending inwardly from the second portion, the shelf defining a panel configured to move outwardly and inwardly relative to the side wall through the shelf during pressure application, the panel comprising a center portion and a plurality of spaced apart radial segments disposed circumferentially about the center portion, the center portion being concave, at least one of the segments being tapered toward the center portion,
- wherein the first portion and the second portion define a gap that separates the bottom wall from the side wall, and
- wherein the gap prevents the bottom wall from rubbing against the side wall during the outwardly and inwardly movement of the panel relative to the side wall.
