Abstract: A flat-bottom bag is provided having a folded bottom. Improved adhesive patterns are provided on the bag prior to folding. A first adhesive is provided in a plurality of parallel lines interiorly disposed in a bottom end of the bag. The lines are arranged on front and rear walls parallel to the side walls so that one outer line is positioned on each side of the front and rear walls with corresponding inner lines positioned so that when the sides are folded inwardly, each outer line intersects and contacts one respective inner line in an overlapping manner. This arrangement provides a securing of all interior edges of the folded bottom. A second adhesive can be applied to the exterior of the bag to bond front and rear flap extensions to each other and to the folded sides, forming the flat bottom. In an embodiment, an outer bottom flap is formed by slits in the front flap extension.

Abstract: A flat-bottom bag is provided having a folded bottom. Improved adhesive patterns are provided on the bag prior to folding. The bag has a generally planar front wall, a generally planar rear wall which is substantially parallel to the front wall, and a pair of gussetted side walls connecting said front and rear walls. A pair of adhesive patterns are provided, one on an interior of the front wall and one on an interior of the rear wall. Each of the adhesive patterns has a pair of squares. A pair of first flap extensions are provided. Each first flap extension has a pair of overlapping triangular sections. The triangular sections are formed by a folding over of the front wall and the rear wall such that each square is folded over diagonally so that the adhesive pattern will overlie itself. Additional adhesive strips secure the first flap extensions to the bottom. This arrangement provides a securing of all interior edges of the folded bottom.

Abstract: A sack or bag has a front wall and a rear wall which are respectively connected laterally by a lateral fold, with a strip of the front wall together with the lateral folds on at least one of the two initially open ends being folded about a first folding line running transverse to the longitudinal axis. The corresponding strip of the rear wall remains in place and the folded-over strip of the front wall, as well as the strip left in place on the rear wall, are once again folded around the outer edge of the folded-over strip and attached in this position on the outside of the sack or bag. To make a sack or bag with a tight, leak-proof bottom portion, a corner tuck each is formed on both sides between the strips of the rear wall initially left in place and the side folds folded over together with the folded strip.

Abstract: A shopping bag for general purpose use in constructed from a sheet of fabric and formed by a series of steps into top and base portions integrally connected to side panels and back and front panels joined by a single seam which extends the length of the bag. The folding operation creates a multiple ply border about the upper or open portion of the bag. Selvage on the fabric is directed to form a portion of the base such to extend around the perimeter of the base integrally connected with the side panels and the back and fornt panels. A pleated construction of the side panels allows the bag to fold compactly when not in use such as when being carried or transported. The mouth of the bag when accepting articles is generally rectangular in shape. The inner and outer creases of the bag are reinforced from top to botton thus imparting to the side panels a rigidity which projects them essentially transversely to the back and front panels when the bag is trimmed for use.
