Abstract

Abstract A one-piece paperboard blank for erecting into a carton for holding and displaying a stacked array of generally flat rectangular boxes includes generally right triangular-shaped sides, a back, a base, and a partially open top portion into which the rectangular boxes are received. The carton includes an inclined support panel disposed wholly within the carton and extending from the top of the back panel to a point intermediate the bottom panel. Cushion flaps are provided inside of the carton contiguous with the opposite sides thereof, whereby the stack of rectangular boxes are disposed at an inclined angle within the carton, and are resiliently gripped by the opposed cushion flaps. The forwardmost portion of the top of the carton is closed by a panel containing indicia.

Claim 1
Independent Claim 248 words
A carton for holding and displaying a stacked array of generally flat rectangular boxes disposed at an inclined angle to the vertical, said carton comprising: a base; first and second upstanding side panels, each of said side panels being hingedly connected to said base, said side panels being substantially triangular in configuration; first and second pairs of cushion flaps, each of said pairs of cushion flaps being hingedly connected to one of said side panels, each of said cushion flaps being substantially triangular in configuration; a composite rear panel formed of four interengaging flaps respectively connected to said side panels and said base; an interior inclined wall member hingedly connected at its top edge to the top edge of said composite rear panel, each of the opposite side edges of said interior wall member being hingedly connected to one of said pairs of cushion flaps; a base support member hingedly connected to the lower edge of said inclined wall member and disposed flush against said base; first and second side support members, each of said side support members being hingedly connected to one of said side panels, and extending from its respective side panel toward the opposite side panel; an inclined indicia panel hingedly connected to said base and disposed one the top surfaces of said side support panels; and a plurality of locking flaps hingedly connected in succession to said inclined indicia panel, said locking flaps being disposed on the lower surface of said side support members.
Claim 2
Dependent Claim 248 words
A carton for holding and displaying a stacked array of generally flat rectangular boxes disposed at an inclined angle to the vertical, said carton comprising: a base; first and second upstanding side panels, each of said side panels being hingedly connected to said base, said side panels being substantially triangular in configuration; first and second pairs of cushion flaps, each of said pairs of cushion flaps being hingedly connected to one of said side panels, each of said cushion flaps being substantially triangular in configuration; a composite rear panel formed of four interengaging flaps respectively connected to said side panels and said base; an interior inclined wall member hingedly connected at its top edge to the top edge of said composite rear panel, each of the opposite side edges of said interior wall member being hingedly connected to one of said pairs of cushion flaps; a base support member hingedly connected to the lower edge of said inclined wall member and disposed flush against said base; first and second side support members, each of said side support members being hingedly connected to one of said side panels, and extending from its respective side panel toward the opposite side panel; an inclined indicia panel hingedly connected to said base and disposed one the top surfaces of said side support panels; and a plurality of locking flaps hingedly connected in succession to said inclined indicia panel, said locking flaps being disposed on the lower surface of said side support members.
Claim 3
Dependent Claim 20 words
