Re-closure device for pop top containers

An improved pop top beverage container having an interior for housing a carbonated beverage which will go flat if left opened for a predetermined period of time, said container including a top lid having a lid opening and a pop top assembly including a tab member lever including a first end portion adapted to be grasped by one or more of a persons fingers for applying a lifting force thereto for opening the container, and an opposite end portion including a lip for bearing down on the surface of the original seal for unseating said seal and exposing the lid opening, and an intermediate portion including a portion containing a rivet means, the improvement comprising:

• said rivet means including a top rivet head having a downwardly disposed stem portion, a bottom rivet head having a upwardly disposed hollow cylindrical stem including a hollow central interior adapted to retainably receive the downwardly distending stem portion of said top rivet therein, said rivet assembly interconnecting said tab member lever with said seal,
• an integrally-formed, double-lobed sealing means wherein each of said lobes is a generally oval-shaped member dimensioned to overlay and cover said lid opening for sealing same, said oval-shaped lobes being interconnected by an integral neck portion, said neck portion being operatively coupled to said rivet means for rotation therewith;
• one of said oval-shaped lobes being originally disposed under said lid opening for covering same in a seal-forming airtight manner, said original sealing lobes being unseated by the downward application of force applied from said opposite end portion of said lip at the opposite end portion of said tab member lever as first end portion is lifted for bending said neck portion before said first oval-shaped lobe into the interior of the container for fully exposing said lip opening;
• and
• the opposite one of said lobes being responsive to the rotation of said tab member lever about said rivet means for repositioning said second lobe under said lip opening and overlying said same for resealing said lip opening to prevent the escape of carbonized gases from the interior of said container so as to prevent the beverage contained therein from going flat, said opposite one of said lobes being responsive to the rotation of said tab member lever in the opposite direction for unseating said seal and reexposing said lid opening for enabling the remaining beverage to be removed from the container.

An improved beverage container having an interior for containing liquid, a lid for sealing the container, and a lid opening, said improvement comprising:

• a pop top tab assembly including a tab member having one end portion adapted to be lifted by the application of force thereto, a pivot means operatively connecting the intermediate portion of said tab member to the lid and the opposite end portion including a lip, said lip being pushed downward in response to the lifting at the opposite end of said tab member;
• a first sealing member dimensioned to overlay said lid opening and being adapted to be operatively disposed beneath said opening within the interior of said container for sealing said lid opening;
• a second sealing member integral with a portion of said first sealing member for resealing said lid opening once said first sealing member has been unseated;
• said first sealing member being responsive to the application of downward force applied thereto by the opposite end of said tab member for unseating said first seal member and bending same into the interior of said container for fully exposing the lid opening;
• and
• means responsive to the rotation of said tab member in a first direction about said pivot means for repositioning said second seal under the said opening for resealing same in an airtight manner to prevent the escape of gas from the interior of said container and responsive to the rotation of said tab member in the opposite direction for reopening said lid opening and reexposing said opening to enable the remaining beverage store therein to be removed.
