Abstract
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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
153 words
In an air-treating article of the type having an enclosure with a permeable film portion which is non-porous and becomes saturated with a volatile composition, through which a volatile composition will permeate to be dispensed to the atmosphere as a vapor, the improvement comprising: (a) a cover member covering the permeable film from manual contact and having openings to facilitate air movement against the film; (b) an impermeable strip under the cover member and peelably adhered to the permeable film to prevent dispensing prior to peeling therefrom; and (c) a leader attached at its proximal and to one end of the impermeable strip, overlying the strip over the length thereof under the cover member, and terminating in a gripping end outside the cover member, whereby the impermeable strip may be peeled away to expose the permeable film by pulling the leader while the cover member remains in place to protect the permeable film.
Claim 2
Dependent Claim
153 words
In an air-treating article of the type having an enclosure with a permeable film portion which is non-porous and becomes saturated with a volatile composition, through which a volatile composition will permeate to be dispensed to the atmosphere as a vapor, the improvement comprising: (a) a cover member covering the permeable film from manual contact and having openings to facilitate air movement against the film; (b) an impermeable strip under the cover member and peelably adhered to the permeable film to prevent dispensing prior to peeling therefrom; and (c) a leader attached at its proximal and to one end of the impermeable strip, overlying the strip over the length thereof under the cover member, and terminating in a gripping end outside the cover member, whereby the impermeable strip may be peeled away to expose the permeable film by pulling the leader while the cover member remains in place to protect the permeable film.
Claim 3
Dependent Claim
16 words
The article of claim 1 wherein the volatile composition within the enclosure is a free liquid.
Claim 4
Dependent Claim
32 words
The article of claim 2 wherein the film and liquid have optical qualities such that the presence of the liquid can be seen through the permeable film, thereby providing a use-up indicator.
