Abstract

Abstract A pest collection-disposal device includes a means for establishing an air stream in an air duct forming at least a segment of a housing for the device. Positioned in the duct is a disposable pest collection cartridge. The cartridge comprises an elongated body having a flexible closure means and a filter means. The closure means deflects under the influence of an air stream from a closed position to provide an entrance thereto for insects entrained in the air stream. The filter means separates insects from the air stream. Upon termination of air flow, the flexible closure member is restored to an initial position to entrap the pest between the flap and filter means. The duct in one embodiment includes an expandable and retractable array of elongated telescoping members. In a further embodiment, the cartridge is positioned in one of the elongated duct members.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 212 words
An improved pest collection device consisting of an expandible and retractable array of interconnected, hollow duct members, at least one of said a duct members is adapted for sliding telescopic motion, said duct members positioned at least partly in an adjacent member to vary the length of the array, at least one of said duct members having an electric power supply compartment, a motor fan compartment, and an insect collection compartment wherein said collection compartment has a disposable-replaceable cartridge means which comprises: an elongated hollow body having inlet and outlet ends, a flexible closure member positioned at said inlet end and is deflectable to provide an entrance to the hollow body when an air stream flows therein, and a filter means positioned adjacent said outlet end of said hollow body through which said air stream flows for removing a pest entrained in said air stream; whereby, the disposable cartridge enables pests to be collected and disposed of without presenting an unsanitary, or unsightly condition, as well as inhibiting escape of insects from within the cartridge during disposal, each of said compartments arranged to enable air to flow into said device at an inlet of said insect collection compartment and flow to said motor fan compartment and to be exhausted from said array.
Claim 2
Dependent Claim 212 words
An improved pest collection device consisting of an expandible and retractable array of interconnected, hollow duct members, at least one of said a duct members is adapted for sliding telescopic motion, said duct members positioned at least partly in an adjacent member to vary the length of the array, at least one of said duct members having an electric power supply compartment, a motor fan compartment, and an insect collection compartment wherein said collection compartment has a disposable-replaceable cartridge means which comprises: an elongated hollow body having inlet and outlet ends, a flexible closure member positioned at said inlet end and is deflectable to provide an entrance to the hollow body when an air stream flows therein, and a filter means positioned adjacent said outlet end of said hollow body through which said air stream flows for removing a pest entrained in said air stream; whereby, the disposable cartridge enables pests to be collected and disposed of without presenting an unsanitary, or unsightly condition, as well as inhibiting escape of insects from within the cartridge during disposal, each of said compartments arranged to enable air to flow into said device at an inlet of said insect collection compartment and flow to said motor fan compartment and to be exhausted from said array.
Claim 3
Dependent Claim 17 words
The device of claim 1 wherein at least one of said duct members is non-tubular in shape.
Claim 4
Dependent Claim 41 words
The device of claim 1 wherein at least one duct member is adapted for telescopic retraction into the interior of an adjacent duct member for storage and for extension from said adjecent duct member to increase the length of the device.
Claim 5
Dependent Claim 25 words
The device of claim 1 wherein a duct member is formed of a transparent polymer plastic having said filter means and closure member positioned therein.
Claim 6
Dependent Claim 22 words
The device of claim 4 wherein said transparent duct member includes an interior surface which is coated inside with a pigmented adhesive.
Claim 7
Dependent Claim 13 words
The device claim 5 wherein said transparent duct member includes an uncoated segment.
