Abstract
Abstract A corrugated, one-piece, die-cut packing pad for insertion into opposite sides of a shipping carton for cushioning and supporting a device transported in the carton and spacing and precluding movement of the device relative to the sidewalls of the carton. The pad has a central, substantially solid front panel inserted between the transported device and a sidewall of the carton and a plurality of relatively pivotable, upright, hinged posts attached to opposite side edges of the front panel which when folded relative to each other in accordian style contact the sidewalls of the carton and serve to clamp the device between the front panels of the pads inserted between the opposite sidewalls of the carton and the device. A top panel is hinged to spaced portions of the top of the front panel and foldable 90° relative thereto to overlie the device during shipment to provide cushioning for the top of the device during shipment.
