Abstract
A solid fragrance carrier comprising a fragrance-containing polymeric matrix adhesively bonded to a filter or filter bag for filtering an air stream in a vacuum cleaner for providing a fragranced scent to air exhausted from the vacuum cleaner.
Claims12
A filter for filtering an airstream in a vacuum cleaner, the vacuum cleaner having a suction source for drawing the airstream from a surface to be cleaned to a debris collector for collecting dirt and debris carried by the airstream, the filter comprising:
- a frame with an edge defining an open area through which air may pass;
- a filter media mounted to the frame and covering the open area;
- and
- an adhesive comprising a fragrance-containing polymeric matrix adhesively bonded directly to the frame adjacent the edge of the frame and directly to the filter media adjacent the edge of the frame to join the frame with the filter media;
- wherein the filter media is secured to the frame by the adhesive bond formed by the fragrance-containing polymeric matrix.
A filter bag for use in a vacuum cleaner, the vacuum cleaner having a suction source for drawing an airstream from a surface to be cleaned to the filter bag for collecting debris carried by the airstream, the filter bag comprising:
- at least one non-porous portion;
- porous walls made from a porous material and defining an interior storage space such that dirt and debris entrained in the airstream are filtered out of the airstream and collected within the interior storage space of the filter bag as the airstream passes through the porous walls;
- and
- an adhesive comprising a fragrance-containing polymeric matrix adhesively bonded to the at least one non-porous portion of the filter bag.
A method of forming a solid fragrance carrier on a filter element in a vacuum cleaner comprising:
- mixing a liquid polymeric gel with a liquid fragrance to form a fragranced gel;
- curing the fragranced gel to form a solidified fragranced gel;
- subsequent to forming the solidified fragrance gel, heating the solidified fragranced gel to soften the solidified fragrance gel;
- applying the softened fragranced gel to a filter element for a vacuum cleaner;
- and
- curing the fragranced gel to solidify the fragranced gel on the filter element such that the fragranced gel adhesively bonds to the filter element.
