  • Patent number: 7451873
    Abstract: A packaging card for holding a refill spool. The packaging card includes a hanger cut-out for hanging the refill spool on a display rack. The packaging card comprises a main panel, a bottom panel, a support panel and an end panel. The main panel is connected to the bottom panel by a hinged connection such as a crease line. The bottom panel and the support panel are connected by a crease line. The support panel is also connected to the end panel by a crease line. The end panel is affixed to a portion of the main panel using an adhesive, and the end panel and support panel form a buttress to support the bottom panel. The bottom panel provides a support platform for holding the spool. The crease lines between the end, support and bottom panels allow the packaging card to be folded flat, for example, for packing and shipping to the refill spool manufacturer.
