ABSTRACT:
An openable seal member for a container includes a tube extending across the sealed area of the container for flow communication between the interior and exterior thereof. A flexible plastic pocket member seals and encloses the outer end of the tube. Tear means are provided for opening the pocket member, comprising a circumferential line of tearing weakness positioned about the pocket member in transverse relation to the longitudinal axis of the tube. In accordance with this invention, a flexible generally conical portion is positioned between the outer end of the tube and the tear means, with the conical portion diverging outwardly and constituting an inner portion of the pocket member, to define upon opening of the seal member, an enlarged, protective area surrounding the outer end of the bore of the tube.
