ABSTRACT:
A sampling bag such as for sampling of liquids or other material is provided with an improved wire-type closure. A pair of wires are connected to the front and rear walls of the bag, and extend outwardly beyond the side edges of the bag. Facing adhesive strips are secured to the front and rear walls of the bag along the length of the wires, and the ends of the adhesive strips extend beyond the ends of the wires. The adhesive strips are secured to each other beyond the wire ends, to enclose the wire ends. In this manner, contact of the wire ends with the walls of the bag is prevented when the wire ends are bent inwardly to close the bag.
