Abstract

A liquid carrying, thermoplastic coated paperboard container including a top end closure, a four-sided body portion, and a bottom end closure, wherein various end closure panels are folded so as to abut against one another to become sealed thereagainst. To effectuate the sealing, a pressure sensitive, food grade adhesive is applied to at least one of each two abutting surfaces and the abutting surfaces are pressed together without the application of heat or high frequency vibration. The adhesive may be applied to the blank during the converting process, or while the blank is being formed into a container on the forming, filling and sealing machine.
