Abstract
Abstract Cushioning unit for use inside a packing box includes a hollow carrier, such as a tube or box, for accommodating the article to be packed, and pieces of resilient material, such as foamed plastic, secured to exterior of the carrier and adapted to engage the inner surfaces of the box walls. Resilient pieces may include a main rectangular pad secured to each end of carrier, and auxiliary pads secured to center of each side of main pad, only the edges of the pads engaging the packing box walls. Alternatively, each main rectangular pad may have spaced pads secured to its sides, spaced pads making face-to-face contact with packing box walls. Resilient buffer may be secured to inner surface of each packing box end wall.
