ABSTRACT:
The collapsible bag is provided with bellows type folds along two opposed sides of the substantially rectilinear bag and a third side of the bag is connected to the two opposed sides by a pair of foldable gussets to allow for an extra large opening at one end of the bag to facilitate the removal of the contents from the bag. The bag may then be refolded into its initial substantially rectilinear shape and the end of the bag may be folded down to a reduced rectilinear size depending upon the volume of the contents left in the bag. After folding down the end of the bag the same may be secured by folding over the ends of a wire which is secured in and extends beyond the folded over end edge of the fourth side of the bag. Suitable stiffening members may be inserted into two sides of the bag and may be either removed or folded down as the contents of the bag diminish to facilitate the reduction in the size of the bag.
