Claim 1
Independent Claim
174 words
A carrier-bag of flexible sheet material formed from a substantially rectangular sheet of said material by folding and seaming, the bag comprising in its flattened, empty state: A substantially rectangular back panel; two front panels lying upon the back panel, each joined along one edge to one of a pair of opposite edges of the back panel, and each front panel extending at least a part but not substantially more than half of the distance between said opposite edges; an extension of the edge of each front panel opposite the said joined edge, each extension being backwardly folded upon the front panel to cover at least a portion of the depth thereof; a handle in or attached to each said extension; and seams extending along each of the two remaining edges of the back panel, said seams joining together these edges of the back panel and the corresponding side edges of the front panels and extensions thereof, the remaining edges and folds extending between said seams and being free across substantially their whole length.
