METHODS OF DELIVERING FRAGRANCE USING ETHYLENE VINYL ACETATE RIBBON
First Claim
1. A substrate in a form of a transparent sheet comprising:
- a copolymer of an olefin and at least one olefin derivative; and
a fragrance,wherein the substrate is substantially free of homopolymeric material,wherein the substrate has a thickness of from about 10 to about 50 mils, andwherein the time required for the substrate to achieve about 50% cumulative fragrance depletion ranges from about 5 to about 40 days.

Abstract
A substrate for delivering a fragrance to the surroundings is disclosed, wherein the substrate comprises: (i) at least one copolymer of an olefin and one or more ethylene derivatives selected from a group consisting of vinyl esters of saturated carboxylic acids, propenyl esters of saturated carboxylic acids, olefmically unsaturated organic acids or esters, and mixtures thereof, and (ii) a fragrance in an amount sufficient to be released to the surroundings at a sustained, controlled rate. Preferably, the substrate is in a form of a transparent sheet so that the substrate can be conveniently and discreetly attached to a surface and deliver a fragrance impregnated therein to the surroundings.
