Abstract
Abstract An elongated tubular bag of plastics film material is heat sealed to form a hermetically sealed container portion for enclosing a predetermined volume of fluid. An elongated handle member of relatively rigid plastics material, extends longitudinally within the container portion and has one or more pointed tip portions. The bag is folded back against the container portion to form a tab portion, and the folded end portion of the bag and the pointed tip portion of the handle member are inserted within a slot formed within a resilient sponge-like swab or applicator. When the projecting tab portion is pulled, the handle member pierces one or more holes within the container portion of the bag so that the fluid may be dispensed into the center portion of the applicator in response to pressure applied to the bag.
