Abstract: A thread and punch lock for article carriers includes a first closure panel with a plurality of spaced tongues along its terminal end. A locking tab is provided in longitudinal line with each tongue and adjacent thereto. The tab extends in opposing direction to the tongue; the tab and tongue together forming a locking unit. The second closure panel includes two substantially parallel, transversely elongated slits for receiving each locking unit when the closure panels are in proper overlapping relation. Disposed between these slits is the closure panel material forming a protector strap. The closure panels are locked together by inserting the tongue through the slit furthest from the edge of the second closure panel. The tab is then punched in the slit nearest the edge of the second closure panel so as to overlie the second closure panel and create edge to edge engagement. The protector strap overlies the tab along the interior of the carrier to hold the tab in locked engagement and provide extra strength.

Abstract: An article wrapper for an article, or plurality of articles in at least one row, is formed from an elongated blank having a top panel, a pair of side panels connected to the top panel along fold lines, and a pair of bottom panels with each of the bottom panels connected to the adjacent side panels at two score lines. Compression tabs are positioned between the bottom score lines to allow tightening of the wrapper by squeeze guides. The bottom panels are arranged in overlapping relation and secured to each other by an adhesive, for example, after tightening the wrapper. The uppermost bottom score line adjacent each of the side panels enables a right angle corner to be formed at the bottom of each of the side panels so that each of the side panels presents an uninterrupted surface. The tabs are tucked under the bottom so as to be hidden from view.

Abstract: An article carrier is formed from an elongated blank having overlapping bottom panels to support articles in at least one row. One of the bottom panels has a plurality of spaced tongues at its terminal end. A plurality of separate locking tabs are longitudinally aligned with each tongue. The other of the bottom panels has transversely elongated apertures with each of the apertures receiving one of the tongues. Each of the tongues has engagement with one transverse edge of the aperture and one of the plurality of separate locking tabs has an edge to edge overlying engagement with the opposite transverse edge of the aperture. Each of the apertures is increased in size in accordance with which of the separate locking tabs overlies the opposite transverse edge of the aperture. Each of the separate locking tabs are selected for use in accordance with the dimensions of the adjacent article or articles supported by the carrier.

Abstract: Apparatus for continuously feeding and controlling wraparound carrier for packaging a plurality of articles or containers is disclosed. The carriers are of the type having at least two draw-down and feed openings, one opening formed on each side thereof. Each carrier is initially partially wrapped about a plurality of containers. The carrier and container assemblies move along a guide track to the entrance of the carton draw-down (tightening) conveyor line of the present invention. The conveyor line comprises a pair of continuously moving timing chains having a plurality of draw-down lugs pivotally attached to and spaced apart along the chain. Each lug includes a tongue portion adapted for insertion through the openings to feed and to draw down the side walls, and also to control the positioning and movement of the containers.
