Abstract
A room air freshener adapted to be used in connection with a register vent. The structure of the freshener is especially formed to be attached to the vent register and includes a formed handle adapted to keep the freshener material adjacent to the grid of the register vent. A certain range in the amount of mass of the freshener is required for a certain volume of air for best operation of the freshener.
Claims25
An air freshener for attachment to a fan stem having forced air flowed relative thereto and comprising:
- a scented clip formed from a flat sheet of polymeric material impregnated with a scented material, said sheet being perforated by a series of openings to allow air flow therethrough, said flat sheet being elongated and formed with legs defining a slot longitudinal of said elongation, said slot having a wider opening along said slot sized to engage said stem to hold such sheet in position on said stem for flow of said forced air through said openings.
An air freshener for mounting through a register vent including an array of louvers arranged to define on one side a working plane, said louvers being angled at a predetermined angle relative to said plane, said freshener comprising:
- a sheet of polymeric material formed with a planar section for laying along said array of louvers in said working plane and impregnated with scented material and formed with a series of air passage openings;
- said sheet further being formed with a handle including a transition neck projecting at said predetermined angle relative to said planar section for, when said section is positioned in said working plane, engaging a selected one of said louvers;
- and
- said handle being further formed with a tongue projecting therefrom and configured to, when said planar section is disposed in said working plane and said handle engaged with said selected one louver, engaging an adjacent louver to cooperate in holding said planar section positioned in said working plane.
An air freshener for insertion between adjacent louvers of an air vent and comprising:
- a planar sheet section of polymeric material for positioning in an installed position in a plane behind said vent, impregnated with scented material, and formed with a series of air passages;
- and
- mounting means including a transition neck, configured to be, when said sheet section is in said installed position in said plane behind said vent, angled outwardly along one of said adjacent louvers, and a tongue configured to angle from said neck to engage the other of said adjacent louvers and cooperate in holding said sheet section in said installed position.
A louver mounted air freshener including:
- a sheet of polymeric material configured with a planar section disposed in a selected plane and impregnated with scented material and formed with a series of air passages spaced throughout;
- said sheet including a transition neck angling away from the plane of said planar sheet at an obtuse angle and configured on the distal extremity with a hand grasp section;
- and
- said hand grasp section including a tongue angling from said handle toward said plane and configured to project at an acute angle relative to said transition neck.
A method of supplying air freshener to an enclosed area having a fixture mounted from a mounting stem disposed in a flow of moving air and including:
- selecting an air freshener constructed of an integral sheet of polymeric material impregnated with a scented material, having openings spaced throughout for flow of air thereinto, and formed with a pair of co-extensive resilient legs spaced apart to form an elongated open ended slot, at least one of the legs formed medially with a cut out confronting the other leg and configured such that it may be received over such stem;
- and
- mounting such freshener from said stem by inserting such legs over such stem to register it with said cut out to position said freshener in said air flow for flow of air into said openings to freshen the air in said enclosed area.
