Embodiment Construction

[0011]Referring now to the drawings, there is illustrated in FIG. 1 an air freshening article, indicated generally at 10, in accordance with this invention. The illustrated air freshening article 10 is, in large measure, conventional in the art and is intended merely to illustrate one environment in which this invention may be used. Thus, the scope of this invention is not intended to be limited for use with the specific structure of the air freshening article 10 illustrated in FIG. 1. On the contrary, as will become apparent below, this invention may be used in any desired environment for the purposes described below.

[0012]The illustrated air freshening article 10 is a urinal screen that is adapted for use in a conventional urinal (not shown), such as commonly found in public restrooms. Alternatively, the air freshening article could be incorporated into or onto a product for automatically flushing a toilet or urinal. Additionally, this invention may be embodied as any one of a wid...

Abstract

An air freshening article, such as a deodorizing urinal screen, includes a body that is formed from a fragranced plastic that includes a plastic loaded with a fragrance material. The fragrance material is included in an amount of at least 15% by weight of the fragranced plastic. A method of producing a deodorizing urinal screen includes a fragrance loading stage in which a plastic is loaded with a fragrance material to produce a fragranced plastic. The fragranced plastic includes at least 15 wt % fragrance material. In a molding stage subsequent to the fragrance loading stage, the fragranced plastic is molded into the urinal screen.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuing application of U.S. application Ser. No. 12 / 152,627, filed May 15, 2008, which claims the benefit of U.S. Provisional Application No. 60 / 930,202, filed May 15, 2007, which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]This invention relates in general to air fresheners for masking or suppressing undesirable odors. In particular, this invention relates to an improved structure for an air freshening article and to an improved method of manufacturing same.[0003]There are many environments in which it is desirable to mask or suppress undesirable odors. For example, it is known that in restrooms, urinals may emit offensive odors. Additionally, in many other environments (typically relatively small enclosed environments), it is desirable to provide fresh or pleasant odors. For example, it is known to provide fresh or pleasant odors within the relatively small enclosed environment of a veh...
