Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 344 words
An assembly for making a container for cake and the like, comprising an elongate paper blank having a plurality of parallel fold lines therein extending parallel to a pair of opposite end edges thereof, said blank having slots and cooperating tabs at the opposite end edges thereof whereby the blank may be folded at the fold lines and the tabs and slots interlocked to define a sleeve, a pair of end blanks each having a main portion and a plurality of peripheral flaps thereon at the side edges thereof, each flap joined along a fold line at the sIde edge thereof to the main portion and having a further fold line spaced between the side edges thereof and extending parallel to the side edges and defining a pair of flap sections, a pair of locking tab means projecting from at least one end edge of the flaps, whereby the flaps may be folded about the fold lines inwardly toward the main portion with the flap sections contiguous to one another and perpendicular to the plane of the main portion, one of the tab means of one flap received behind the flap sections of an adjacent flap and the other tab means of said one flap received between the flap sections of said adjacent flap, to define an upstanding peripheral wall secured only by the interlocked tab means and flaps, one of said end blanks having a bottom plate secured thereto on the side thereof opposite the peripheral wall and having edge portions projecting outwardly beyond said wall, the peripheral wall of said one end blank having a size such as to be received in one end of the sleeve with said one end of the sleeve supported on the outwardly projecting edge portion of the bottom plate, and the peripheral wall of the other end blank having a size such as to receive the other end of the sleeve therein, said sleeve being foldable to a collapsed position and the end blanks cooperable with one another to define a container for the collapsed sleeve.
