Abstract: The present invention overcomes many of the shortcomings inherent in previous containers for packaging potato chips and/or crisps, corn based chips and/or crisps, cookies and the like. The improved implosion-resistant container of the present invention utilizes flowing geometries mechanisms which allow a hermetically sealed container to smoothly change its geometric shape thereby adjusting its internal volume in response to changes in environmental conditions.

The improved container of the present invention may also include a variety of other stress dissipating mechanisms that counteract the forces causing thermo-plastic container deformation, implosion and loss of seal integrity.
