ABSTRACT:
A packaging system for receiving an article into an open, rectangular foldable container without lifting the article relative to the container. The open foldable containers include four vertical walls, a pair of bottom end flaps depending from a pair of walls, and a pair of bottom side flaps depending from the other pair of walls. The pair of bottom end flaps are formed with at least two vertically extending slots which are spaced apart from each other. Each of the bottom flap members is initially coplanar with the respective walls, with the bottom of the container being open. The packaging machine includes a conveyor system including a number of chains which are equal to the number of slots formed in the bottom end flaps of the container, the chains extending parallel to each other and are spaced apart so as to correspond to the spacing of the slots. An article to be packaged is introduced onto the conveyor system, and the container is placed therearound with the container oriented such that the pair of bottom end flaps are distributed in vertical planes perpendicular to the length of the chains and with the slots in the pair of bottom end flaps being fitted over the respective chains. The packaging machine also includes means located along the conveyor system for folding the pair of bottom end flaps to a closed position while the container is placed around the article on the chains. The pair of bottom side flaps of the container are then folded to a closed position by known folding means.
