ABSTRACT:
A divided cell carton for fragile articles, such as eggs, has a tray portion with divider walls providing a plurality of open top cells and a lid portion with a central longitudinal channel having alternating depending struts bottoming on the divider walls and depending straps between the struts. Each strap has a pair of opposed resilient fingers positioned to bias the articles in adjacent cells against the bottoms and sides of the cell walls for firmly seating the articles in the cells. The inner ends of the fingers of each pair are connected by a resilient bridge acting as a hair pin spring to stiffen the fingers. The bridge configuration may have many different forms to suit conditions so that the fingers will be effective to act on articles of different sizes in the cells, thus providing a standard size carton that can safely house articles of many different sizes.
