ABSTRACT:
A plastic bag opening device has a flexible U-shaped member which can be slipped over the slit edge of a plastic bag. Adhesive means which are affixed to the inside of the ends of the U-shaped member contact the sides of the plastic bag when the U-shaped member is forced to a closed position. As the U-shaped member is flexed to an open position the sides of the bag adhere to the respective adhesive means and are pulled apart from each other. The ends of the U-shaped member are held apart by inwardly facing protrusions yet a positive clamping action of the adhesive means on the sides of the plastic bag is obtained by a pair of inwardly facing tips.
