PACKAGING AND FILLING DEVICE, PAPER CONTAINER, AND BLANK

摘要

The present invention provides a packaging and filling device, a paper container, and a blank in which appropriate measures can be taken against penetration leakage from an end surface. For a blank for a paper container that has an upper part, a bottom part, and a cylindrical main body having four side walls and a square cross-section, and is formed by a packaging and filling device, the packaging and filling device comprises a loading means for retrieving the blank and loading a cylindrical blank, a bottom-part-molding means for molding the bottom part of the cylindrical blank and obtaining a container, a filling means for filling the container with a liquid food item from an upper opening, and an upper-part-sealing means for heat-sealing the upper opening.
