ABSTRACT:
A vacuum seal container comprises a cylindrical container body having a peripheral seal extending therearound and a lid including an outer skirt for engaging the seal. The skirt defines an access port for communication with a vacuum-generating source. The lid further includes seating nodes which seat the lid in a raised position to form an interior air passageway for air evacuation. At reaching a threshold pressure difference between the inside and outside of the container, the seating nodes and the sidewall deform to lower the lid which blocks the interior air passageway to form a vacuum seal.
