The outer section defines a removable section which has a first perforation generally parallel to the back seam and an edge that is generally parallel to the bag bottom and intersects the first perforation. Alternatively, a second perforation may be provided along the edge. The outer panel is about as wide as the bag and the removable section is less than one-half the width of the outer panel. The first perforation is positioned between the back seam and side edge of the removable section. The first perforation may be adjacent the back seam and the second perforation is adjacent the bag bottom.A blank for forming said bag from a web is also disclosed.

Abstract: A stabilized flexible container for receiving flowable materials includes a top wall, a bottom wall, and a perimeter wall formed from four double layered side walls seamed together along adjacent side edges. The exterior layer of the double layered side walls is greater in length than the interior layer and is folded inwardly upon itself and stitched along the side edges to form a pocket in a space between the interior and exterior layers of the double layered side wall with the side edges of the exterior layer in the pocket region being free from the seam connecting the adjacent side walls. The interior layers of the side walls are seamed together in the pocket region and are seamed along their bottom edges to the perimeter of the bottom wall. Rigid panels are inserted into the space between the interior and exterior layers of the side walls and are secured in the pocket to prevent the rigid panels from slipping out of the side walls.

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.

Abstract: A disposable or reusable and reclosable gussetted plastic bag capable of being compactly stored as a food container in freezers, yet capable of standing with an upright spout in a microwave oven for non-spill thawing and cooking of food contained in the bag. The bag is formed of two wing-shaped pouches on either side of the upright spout. The bag preferably has inner and outer skin layers of different heat sealing temperatures so that peripheral sealing is effected only with the inner skin layers, allowing the wing-shaped pouches to be formed out of a gussetted bottom without sealing of the outer skin layers of the gusset walls facing one another. Two pairs of relief seals are located adjacent each gusset joint at both edges of the bag. Each seal is positioned 45.degree. off the gusset joint and preferably has a rounded peak shape. The heat seals are formed by applying heat adjacent each gusset joint with a hot bar or other heat sealing device following formation of the bag.

Abstract: A self-expanding flexible pouch that can be used as the measuring device for reconstituting a concentrated product contained therein. The flexible pouch includes an extensible stay located in the throat area of the pouch that is biased toward a circular or elliptical configuration but initially held substantially flat in a stressed condition by the pouch's sealed top portion. When the pouch's top portion is removed, the extensible stay expands to its unstressed circular configuration and thereby expands and opens the pouch's throat area.
