Abstract
Abstract A composite container is provided for use in the bulk handling of comminuted materials and the like. The container includes a foldable outer carton having sidewall panels and full overlapping end closure flaps which cooperate to define a productaccommodating compartment, and a pliable bag disposed within the compartment and having an open upper end for product loading. The wall portions of the bag are affixed to the interior surfaces of the carton sidewall panels and the portions of the bag circumjacent the open upper end are releasably affixed to the closure flaps defining the carton upper end. The bag portion of the first folded closure flap projects beyond the distal edge of the flap so that the projecting bag portion overlies a portion of the bag attached to a second closure flap, opposed to said first folded closure flap, and thus, retains the projected bag portion in linear contact with the overlapped bag portion of the second closure flap at the fold line connection between the second closure flap and a sidewall of the container.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
218 words
A composite container comprising a foldable carton having four sidewall panels foldably interconnected and defining a product-accommodating compartment, and closure flaps foldably connected to the top and bottom edges of said sidewall panels and being foldable into overlapping relation so as to form top and bottom end walls for the compartment, a first of said closure flaps forming the top end wall spanning the entire distance between the opposed sidewall panels defining said compartment; and a pliable bag disposed within said compartment, said bag having a closed bottom subtended by the carton bottom end wallforming closure flaps, wall portions of said bag being affixed to the interior surfaces of said sidewall panels forming said compartment, and portions of said bag circumjacent the open end thereof being releasably affixed to the carton top end wallforming closure flaps, the segment of the bag releasably affixed to said top end wall-forming first closure flap projecting beyond the distal edge of said first folded closure flap and said bag segment overlying a portion of the bag attached to the inner surface of a second closure flap opposed to said first closure flap at the foldline connection between said second closure flap and a sidewall panel, whereby the overlying bag segment and bag portion are retained in linear contact at said foldline connection.
Claim 2
Dependent Claim
