Seal for flexible container having flexible, generally conical portions

An openable seal member for a container having an interior defined by a peripheral sealed area, said seal member comprising a first tube having an outer end and adapted to extend across a section of the sealed area with said outer end in flow communication with the container interior;

• a plastic pocket member including a generally conical flexible inner portion extending axially outwardly from said first tube outer end and defining a protective area resiliently disposed toward a generally circular configuration radially of the first tube axis and surrounding said first tube outer end, said pocket member further including a flexible outer portion extending axially outwardly from said inner portion and sealingly closing said first tube outer end and said surrounding protective area, said generally conical inner pocket member portion being flexibly retained by said pocket member outer portion in a generally oval configuration radially of the axis of said first tube;
• means defining a preweakened tear line extending circumferentially about said pocket member generally between said inner and outer portions thereof and operative for permitting the manual separation of said outer pocket member portion from said inner pocket member portion, thereby opening said pocket member for access to said first tube outer end, said generally conical inner pocket member portion resiliently returning upon said separation toward said generally circular configuration;
• and an inner tube mounted within said first tube, said inner tube defining a rupturable member positioned at a location spaced from said first tube outer end and sealing the interior of said pocket member from the container interior.
