Abstract
Abstract A cushioned folder for a flat article such as a book or the like is provided with protecting cells on the four boundaries thereof. The folder is formed from a cut and scored blank of paperboard or the like to provide foldably interconnected major and minor walls connected as a tubular sleeve. A cavity is defined in the folder for a flat article and consists of first and second flaps connected to opposite sides of one of the major walls, the flaps being foldable into position to embrace opposite sides of the flat article. The first and second flaps partly define cells for protecting opposite ends and sides of the article, one of the major walls and one of the flaps defining extensions upon folding of the flaps to position, these extensions being embraced by closure flaps which are folded to define a pair of opposing protecting cells. The first and second flaps and one of said major walls are slit to provide tab elements cooperating with the minor walls for defining protecting cells for the ends of the article.

403 words
A cushioning folder for a book or similar article, said folder being formed from a cut and scored blank of paperboard or the like and being characterized by cells disposed along all edges thereof for protecting an article to be positioned in said folder, said folder comprising: a. first and second generally rectangular major panels hingedly interconnected by a minor panel disposed therebetween, said major panels being folded relative to one another to place one of said major panels in an overlying relationship with the other of said major panels; b. said first major panel having a plurality of first flaps and a second flap foldably connected to each of the two free parallel edges thereof which are adjacent said minor panel; c. said first flaps being foldably connected to said second flap and to said major panel with said first flaps being in abutting relationship with opposed edges of an article positioned on said major panel and said second flaps being in overlying relationship with respect to said article; d. cell forming means formed from said second flaps and said major panel to partly define cells for protecting two edges of said article, said cell-forming means comprising an extension from said major panel and an extension from said second flap when said second flap is folded to a position of abutting relationship with said article, said extensions extending outwardly from said two free parallel edges; e. additional cell-forming means formed from said first and second flaps and said major panel, said addItional cushioning means being adjacent the ends of said flaps and being parallel to said minor panel to partly define cells for protecting said article along the two remaining parallel edges of said major panel; f. each of said additional means comprising tab elements from said first major panel and said first and second flaps and partially defined by cut lines positioned parallel to the remaining parallel edges of said major panel each of said tab elements forming a barrier between said article and the corresponding edge of said major panel; 22 g. said minor panel being in abutting relationship with said tab elements; h. additional first and second flaps formed adjacent an edge of said second major panel in parallel relationship with said minor panel with said additonal first flap being in abutting relationship with said tab elements and said additional second flap being secured to said first major panel.
