Abstract

See full text

A pump mechanism for vacuum sealing an airtight cavity formed by a container and a lid, including a bore having a first one-way seal allowing air from the airtight cavity to enter the bore and blocking air inside the bore from returning to the airtight cavity and a second one-way seal allowing air inside the bore to leave the bore without returning to the airtight cavity and blocking air outside of the bore from entering the bore, a piston disposed inside the bore, and a chamber of air enclosed by the bore, the first and second one-way seals, and the piston, wherein actuation of the piston in a first direction causes air to evacuate the airtight cavity and enter the chamber through the first one-way seal, and wherein actuation of the piston in a second direction causes air to exit the chamber through the second one-way seal.
