ABSTRACT:
An air-treating article of the type having an enclosed volatile composition which will permeate through a film to be dispensed to the atmosphere. A grill-like cover member protects the film from human contact and a peelable impermeable strip under the cover member is adhered to the film until it is peeled away by means of a leader. The leader is attached at its proximal end to one end of the strip, overlies the strip under the cover member, and terminates in a gripping end outside the cover member. The strip may be peeled away to expose the film while the cover member remains in place protecting the film. In preferred embodiments the composition is a free liquid, and a use-up indicator is provided.
