Abstract
Abstract A carton filled with a chain of interconnected open bags arranged in a plicated array is disclosed. A process for filling the carton is disclosed in which the chain of bags is fed into an inverted container, closed end first, with the bags being laid in horizontal layers. Each layer is folded back on the preceding layer to produce a plicated array. At the completion of carton loading, the trailing edge of the web preferably is fed along one end wall of the container and out an opening near or at what will become the top of the container. The container is then closed and inverted. The first bag in is the first bag out and it is positioned adjacent to a dispensing opening. The last bag in, which will be the last bag out, also projects exteriorly of the carton and is fixed in place as by taping it to the side of the carton. The plicated array has alternate folds spaced inwardly from the ends of the container.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
166 words
A method of shipping and dispensing a web of interconnected bags each open along one face at its top comprising: (a) feeding the bags, closed end first, into an inverted carton through an opening near the bottom of the carton; (b) positioning the web in layers parallelng the top of the carton by feeding the web back and forth zig-zag fashion to arrange the web in layers with folds at both ends of each layer; (c) forming alternate folds near each end of the carton first adjacent to and then spaced from the end to develop a relatively flat plicated array while allowing the weight of the web itself to compress the array; (d) closing the bottom of the carton once filled; (e) transporting the carton and its contents to a dispensing station and positioning the carton right side up at the dispensing station; and, (f) dispensing the bags from the top of the carton on a first in, first out, last in, last out basis.
Claim 2

Claim 4
Independent Claim
125 words
A method of packaging for dispensing a web of interconnected bags each open along one face at its top comprising: (a) feeding the bags, closed end first, into an inverted carton through an opening near the bottom of the carton; (b) positioning the web in layers paralleling the top of the carton by feeding the web back and forth zig-zag fashion to arrange the web in layers with folds at both ends of each layer; (c) forming alternate folds at each end of each layer to develop a plicated array; and, (d) feeding a last bag in the web from the bottom along a reach between the array and a wall of the carton and positioning the last bag near the top of the carton.
Claim 5
Independent Claim
125 words
