A sealing mechanism for sealing thermoplastic-coated container sealing fins, including a movable sealing jaw and an oppositely disposed fixed sealing jaw. The sealing jaws have parallel, dead-ended grooves formed in the sealing surface thereof, wherein two adjacent grooves cross each other in an X-configuration at their longitudinal mid-point. Engagement of the inter-groove lands against heated outer sealing panels causes the thermoplastic to become molten and flow to the X-configuration area. When cooled, the concentrated thermoplastic serves to seal off the crevice between adjacent folded-over, inner panel segments of the container sealing fin.

Sealing mechanism

A top closure arrangement for an oblong rectangular, gable top container, wherein selected score lines are formed on the wider top closure panels defining panel segments for inward folding during the sealing process. A pour spout fitment is thus mounted on one of the narrow, outer flat closure panels for more convenient handling of the container by the consumer during the pouring process.
