Abstract
Abstract Preferrably made of a one-piece blank of relatively stiff paper material, a book cover when unfolded, forms a horizontal tube structure comprising rear and bottom walls and a front upwardly, rearwardly slanted panel to support a book. This front panel has two full-height slits, spaced equally from each side edge respectively, and two side flaps swung to lie on its undersurface and extending beyond the slits respectively; the marginal lanes of the distal edge of each flap being pasted to the underside of the front panel, only between the slits, thereby forming pockets, the slits being the entrances thereto respectively for the book''s cover panels.

In a book cover-easel combination, a book cover made of relatively stiff and resilient paper sheeting, or the like, and adopted to form a horizontally positionable triangular tubular structure, comprising: a rectangular base panel adapted to rest on a horizontal surface; a rectangular front panel, hingedly connected along one major edge of said base panel and adapted to lie flat against said base panel or to slant rearwardly and upwardly away from said one edge; a rectangular leg panel hingedly connected to the upper edge of said front panel and adapted to lie against said front panel or to fold downwardly toward the opposite major edge of said base panel when said front panel is slanted upwardly from said base panel; at least two trapezoidal flap portions, each being hingedly connected to the opposite major edge of said base panel, said flap portions being adapted to extend upwardly to cover a portion of the external surface of said leg panel, adhesive means adjacent the distal free edges of said flap portions, said adhesive means being located on one side of said flaps portions so that when the structure is folded to form a triangular tube or easel the flap portions are attached to the external surface of the leg panel; first and second flap elements hingedly connected along the minor opposite edges of said front panel, glue lanes along the distal free edges of said flap elements whereby these elements are adapted to be secured to the back surface of said front panel; and said front panel having two spaced slits, parallel to the minor edges of said front panel and located adjacent the minor edges of said panel so that the slits lie between the respective glue lanes and the hinged edge of each of said flap elements when the flap elements are attached to the back of said face panel so as to form two pockets within said front panel adapted to receive opposite lid portions of a book and adapted to retain a book to said front panel when said cover is in its closed folded position and also when the front panel and leg panel are opened out to form a triangular easel.
