Vacuum container with reclosable sealing closure having a vacuum release sealing button

A vacuum container assembly adapted for enclosing a food product, comprising a cup-shaped container including an upper peripheral rim portion defining an open top chamber, a closure covering said chamber and having a peripheral skirt portion, a releasable and reclosable coupling connecting said skirt portion of said closure to said rim portion of said container, a fluid-tight seal between said closure and said rim portion and for holding a partial vacuum within said chamber, said closure having an integral and upwardly projecting inverted cup-shaped vacuum release button defined by a score line and a flexing portion within said closure, said score line partially surrounding a base portion of said button, a sealant material extending upwardly into said button and having an outwardly projecting lower flange underlying said score line and releasably bonded to a bottom surface of said closure, said flange of said sealant material being effective to peel away from said closure in response to downward pressure on said button for defining a vacuum release passage between said closure and said flange, and said flange of sealant material being effective to return into contact with said closure for reclosing said vacuum release passage in response to releasing the downward pressure on said button.
