ABSTRACT:
The specification discloses a plastic collapsible article carrier having open and collapsed positions and adapted to be formed by the injection molding of plastic within opposing dies. The article carrier includes first and second end walls parallel to one another when the carrier is in the open position. The carrier further includes first and second side walls parallel to one another, which are hingedly joined to edges of the first and second end walls to extend perpendicularly to the first and second end walls when the article carrier is in the open position. Portions of the side walls have heights less than the height of the end walls. The first side wall is vertically spaced from the second side wall such that portions of the side walls are vertically offset to enable molding thereof in opposing dies. The article carrier is divided into a plurality of receiving cellular compartments between the first and second side walls by first and second dividing walls disposed parallel to one another and parallel to the end walls. The dividing walls are hingedly joined at spaced locations between the first and second side walls. A bottom member is hingedly joined to edges of at least one of the walls, wherein the article carrier may be folded about the hinged attachments to a flat collapsed position and folded to the open position to form a plurality of open ended cellular compartments for receiving articles such as beverage bottles and the like.
