Snapping the blockade overhang of the box package applying and at with respect to arrival manner and

摘要

PROBLEM TO BE SOLVED: To provide a method which prevents the occurrence of wrinkles due to thermal pressure and prevents the occurrence of a gap between a closed seal and the upper surface of a box-shaped package when a band-shaped closed seal including the overhangs of the upper ends of the box-shaped package is folded down so as to laminate the overhangs on the side surfaces of the closed seal, and also to provide a new device used for the same.;SOLUTION: The box-shaped packages are intermittently carried on a conveyer while being sequentially filled with tea bags or the like in a group of a predetermined number. The package has an opening provided with overhangs on both the sides thereof. Both the overhangs are abutted and sealed in a band shape, and then the band-shaped closed seal is folded down toward the side surfaces of the package (1). The external surfaces of both the sides of the box-shaped package under the overhangs on both the sides of the closed seal are preheated enough for fusion, and the overhangs on both the sides are folded down and superposed upon the external surfaces of both the sides of the package, thus the overhangs and the external surfaces are internally fused with each other.;COPYRIGHT: (C)2003,JPO
