Abstract
A paperboard tray for holding spaced rows of flat articles. A divider separating the rows includes sloped walls which, along with sloped wall portions in the side panels of the tray, serve to support the articles. A web connecting an outer end flap to a divider wall acts as a stop member to automatically position the end of the inner end flap as the overlapping flaps are moved into position during the formation of the tray from a blank.
