       BACKGROUND OF THE INVENTION 
       [0004]    1. Field of the Invention 
         [0005]    The present invention relates to garbage bags and particularly to a flow-through fragrance filter patch which is mounted in a venting aperture of trash bag, which allows for release of air trapped between the trash bag and the trash receptacle and which scents the escaping air. 
         [0006]    2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 1.98 
         [0007]    Most trash receptacles are lined with plastic garbage bags; however a problem occurs when filling the trash bag in that the air trapped between the bag and the receptacle prevents the bag from being filled completely, as shown in  FIG. 1 . When the plastic trash bag is inserted into a trash can and the bag is stretched over its top rim, air is trapped between the can and bag. When garbage is loaded into the plastic bag, the trapped air can prevent filling the bag to more than 50 percent capacity. A user must release the trapped air by removing the bag from the top rim of the can and re-stretching the bag over the top rim. These actions are time consuming and the released air is often unpleasant. Vented trash cans and vented retaining clamps or rings for the bags have been proposed as a solution to the problem, but often the bag retainers take as much time to employ as releasing the bag from the top of the can and vented trash cans present a mess if the plastic bag leaks. 
         [0008]    Conventional trash bags do not provide an effective means for controlling odors. Some plastic bags are impregnated with odor eating compositions or have fragrances added to the plastic during the manufacturing process, but this does not help with the problem of trapped air between the plastic bag and the trash receptacle. 
         [0009]    U.S. Patent Application #20070248291, published Oct. 25, 2007 by Reeves, indicates a vented plastic bag which is adapted for containing a powdery product. The plastic bag includes a plurality of walls joined together and formed of a flexible plastic material. The walls define a fill opening for receiving the powdery product into the plastic bag. At least one of the bag walls defines a ventilation zone including a plurality of spaced-apart perforations. A filter medium overlies the ventilation zone and covers the plurality of perforations to substantially capture and retain the powdery product within the plastic bag during fill and ventilation. 
         [0010]    U.S. Pat. No. 6,135,637, issued Oct. 24, 2000 to Kim, claims a compressible disposal plastic trash sack having series of vertical air slots made up of fine perforations on upper portions of both sack walls that break open from stress of compression to allow excess air inside sack to discharge to outside atmosphere. The discharge of air facilitates sack to compact upon its self and flexible trash contents within, further minimizing sack volume and continually maximizing receptacle holding capacity for the duration which compression is generated by weight of other sacks or applied by persons. U.S. Pat. No. 5,213,141, issued May 25, 1993 to Dorman, describes a debris collection and disposal system for collection and transfer of lawn debris consists of a vented collapsible bag and a rigid container, for structure for releasably inter-engaging them in mouth-to-mouth relationship. 
         [0011]    U.S. Pat. No. 2,092,969, issued Sep. 14, 1937 to Gustafson, indicates a vented garbage can liner in which apertures are provided in the liner to vent the air between the liner and the receptacle. 
         [0012]    U.S. Pat. No. 6,808,073, issued Oct. 26, 2004 to Cuisinier, shows a bag assembly with a connection means for temporarily binding nesting bags to each other and preferably for later additionally acting as a closure means for those same bags. The assembly is configured such that an adhesive is revealed when a nested bag is removed from the assembly. That same adhesive then provides a closure means for the orifice of the bag. Furthermore, the bag body, and identical bag bodies, may possess air holes. Air holes are positioned and structured to allow trapped air between the nested bag bodies and trapped air between the bag assembly and the support device to escape. 
         [0013]    U.S. Pat. No. 4,978,231, issued Dec. 18, 1990 to Ling, puts forth a multiple disposable plastic bag assembly comprised of multiple disposable plastic bags nested one within another to form a bag assembly, characterized in that sticking elements are made on the circular top edge of the opening of the bag body for sticking of the bag assembly to a wastebin to allow the disposable plastic bag assembly to be torn up consecutively bag by bag so as to minimize time consumption in placing individual bags in a wastebin and to facilitate packing up garbage within a bag of the assembly. The two opposite large surfaces of the bag body are provided with a plurality of fine air holes to prevent air collection between the wastebin and the bag body so as to facilitate placing of the bag assembly in a wastebin. The fine air holes are in the form of arcuate slits. 
         [0014]    U.S. Pat. No. D525,877, issued Aug. 1, 2006 to Wingfield, concerns the ornamental design for an air-vented tieless trash bag with elastic cord. 
         [0015]    U.S. Pat. No. 6,003,717, issued Dec. 21, 1999 to Long, illustrates a combination of loop-tie trash liner in combination with a trash container, and a method of using them to dispose of waste material. In the preferred embodiment, there is a notch in the edge of the opening of the bag, between two openings of the tubular channel, whereby air may be vented when the bag is placed inside the trash container. The trash liner is a bag having an opening and a body without perforations, with the opening of the bag having an edge within which is a tubular channel, and a flexible tying member passing through the tubular channel. Opposite ends of the tying member extend from openings in the tubular channel. The trash liner may be fastened on a trash container by inserting the body of the bag into the trash container, placing the edge of the opening of the bag over the rim of the trash container, and tying the opposite ends of the tying member together. Trash placed within the trash container may be safely removed by untying the ends of the tying member, removing the edge of the opening of the bag from the rim of the trash container, closing the opening of the bag, and again tying the ends of the tying member to secure closure of the bag. 
         [0016]    U.S. Patent Application #20070020410, published Jan. 25, 2007 by Sasine, describes a method and process of collecting, packaging and processing recyclable waste which shows, in  FIG. 5 , plastic bags that include one or more air release holes. The release holes are formed near the neck of bags and are configured to allow air to be easily released from bags when bags are compacted by a baler.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0039]    In  FIG. 1 , a prior art trash container with an air impermeable prior art trash bag  40  traps air  50  between the trash container  60  and the bag  40  with the top of the bag sealed around the top rim of the trash container. 
         [0040]    In  FIGS. 2-5 , a vented fragrant air release filter device  10  for a trash bag  40  comprises a patch  20  formed of an air release filter material  21  impregnated with a scent to produce a fragrance in air  50 A passing through the filter material and an adhesive border  22  for adhering the patch  20  to the bag  40  over an air release hole  41  through the bag near the top. 
         [0041]    In  FIGS. 2-5 , a patch  20  adheres to a plastic trash bag  40  over a hole  41  through a side of the trash bag  40  spaced near a top opening in the trash bag. The patch comprises a flat strip of air permeable filter material  21  impregnated with a scented substance for imparting a fragrance to the air  50 A passing through the filter material  21  and an outer border  22  around the filter material having an adhesive on one face of the border to adhere the patch  20  to the bag  40  around the hole  41  for filtering all of the air passing through the hole. The patch  20  is positioned so that with the bag  40  inserted in a trash container and the edge  42  of the top opening in the bag draped over a top rim around a trash container  60  opening, the patch releases air  50 A from between the trash container and the bag  40 , so that the bag can be filled completely to the total size of the trash container interior with no trapped air between the bag and the trash container and impart a fragrance to the air passing through the filter material. 
         [0042]    In  FIGS. 4 &amp; 5 , the patch  20  comprises a sheet of adhesive material adhered to the filter material  21  with the sheet of adhesive being larger in area than the filter material so that the outer perimeter of the adhesive sheet overlaps the filter material to form the adhesive outer border  22 . The adhesive sheet contains openings therethrough permitting the filter material to admit the released air therethrough. 
         [0043]    The patch further comprises a peel-off cover strip over the adhesive border so that the cover strip is removable to adhere the patch over a hole cut in an existing trash bag. The hole through the bag  41  is cut and the patch adhered over the hole in a production run of a number of bags and a quantity of the bags containing patches are packaged together. 
         [0044]    In use, with the Fragrance Filter Patch Bags of the present invention air escapes from between the bag and the can through the Fragrance Filter Patches so the trash can gets completely filled easily without air between the bag and the can to prevent the trash from filling the can. The air is scented by passing through the Scented Filter Patch to cover up the trash smell for a more pleasant experience in filling or emptying the trash can. New Hunter Fragrance Filter Patch Bags have a single Fragrance Filter Patch near the top of the bag to allow the air to escape from between the can and the bag and to scent the air at the same time with any of a variety of scents imparted to the air by the filters which are impregnated with a scent. 
         [0045]    It is understood that the preceding description is given merely by way of illustration and not in limitation of the invention and that various modifications may be made thereto without departing from the spirit of the invention as claimed.
