ABSTRACT:
A dust bag for applying powder insecticide to animals includes an outer mesh bag, an inner mesh bag, a waterproof lining between the two bags, and a double bag cartridge for containing the insecticide. The inner bag is placed inside of the outer bag with a dust chamber presented between the bottom ends of the bags to receive powder passing through the inner bag. The inner bag is characterized by a closer mesh weave than the outer bag, and the two woven bags cooperate with the waterproof lining to prevent rainwater from contaminating the powder while metering the flow of the insecticide to the animals. The cartridge is supported on the bottom of the inner bag and comprises a double bag arrangement with offset holes in the two bags for preventing water entry. The invention also contemplates a novel closure structure for a bag wherein a U-shaped hanger is coupled with a flap which closes an opening in the bag. An arm projects from each end of the U-shaped hanger and flexible cable means is wrapped around the arm to cause a moment which forces the flap into its closed position. An alternative load opening and closure comprises a slit through the bag oriented approximately 20.degree. from vertical and a similarly angled waterproof strip having velcro fasteners for closing the slot.
