Abstract

A shipping container comprising a carton and a liner bag therein. The open end of the bag extends above the horizontal plane of the closing flaps of the carton to an extent exceeding the width of a flap. The top of the bag is closed by elongating and bringing together opposite sides to form a flexible body longitudinally parallel to and extending between two opposing flaps of a pair. The carton and bag are simultaneously closed and a substantially tight seal for the bag is formed by first infolding one of the flaps of the pair, and thereby the body. Thereafter, the opposing flap of the pair is infolded, which also folds the body again and interleaves the body between the two flaps to form two longitudinal closure folds. The body may be of sufficient length to be folded over the second flap to form an additional closure fold. Finally, the flaps of the other pair are infolded whereby the folded body projecting over these flaps is infolded to form transverse closure folds.

Claims

1. A lined shipping container comprising:

a. a quadrilateral carton having a body portion, a closed end for the body portion, and hinged top flaps arranged in opposed pairs;

b. a liner bag within said carton, said liner bag having a content portion and a closure;

c. said closure being formed by contacting elongated opposing side portions of said bag;

d. said closure extending above the horizontal plane of said top flaps of said carton;

e. said closure further extending substantially parallel to and between one pair of said opposing carton flaps with the vertical dimension of said closure being substantially greater than thE width of the flap of said pair of carton flaps so that the infolding of one of said pair of carton flaps covering a portion of said closure and the infolding of the opposing flap of said pair together cause the interleaving of the remainder of the closure between the flaps to thereby form two longitudinal closure folds;

f. the remainder of said closure extending beyond the lastfolded flap of said pair of opposing flaps, which remainder is folded over the last-folded flap to provide an additional and third closure fold, and the ends of the folded-over closure projecting over the other pair of opposed flaps in the infolded condition to form transverse closure folds.
