Abstract
Abstract An improved laundry bag is disclosed which includes a combined bag closure and support band or flap having a specially configured lower edge which intersects the side seams of the bag at an acute angle. This angle of intersection distributes stresses developed in use in the closure and support band or flap so that the tendency to tear at the side seams or elsewhere is reduced substantially. The bag preferably is made from bias-cut material, which minimizes puckering of seams and adds extra stretchiness to the product. The bag also includes an improved form of handle pocket at its lower end. A method of manufacture which minimizes material wastage is also disclosed.

Claim 1
Independent Claim
161 words
In a bag which includes a wall portion and a flap secured to the upper portion of said wall portion, said flap having a bag-open position in which said flap forms a pocket with a downwardly directed mouth to receive a means for supporting said bag, and a bag-closed position in which said pocket has been pushed inside out and slipped over an opening in the top of the bag, said flap being attached to opposite sides of the wall portion by a pair of upstanding seams, with which the lower edge of said flap intersects, the improvement characterized in that said flap, when laid flat in an unstretched condition, is narrower at the center than at the side edges thereof, and said lower edge, viewed with the flap in both the bag-open position and the bag-closed position, intersects with each of said seams at an acute angle, said flap being otherwise free of seams which intersect with said lower edge.
Claim 2
Dependent Claim
