Embodiment 1

[0066] A fragrance emitting pad according to the present invention may be constructed comprising a 30 gsm primary layer of spunlace nonwoven material, and a second non-porous layer of 10 gsm polyethylene film. Has a solubility parameter δ of 14.8 ca A sytrenic block copolymer structural adhesive of ® , in an amount of 5 gsm, was applied to the bottom surface of the primary layer to adhere the primary layer to the second layer. The bottom surface of the second layer is provided with a solubility parameter δ of 15 pa The styrenic (sytrenic) block copolymer positioning adhesive. will be given by having a solubility parameter δ of 22.2 f A fragrance consisting of eugenol was applied to the top surface of the primary layer in an amount of 10 gsm. In this example, the absolute difference between the solubility parameters for the structural adhesive and the fragrance is 7.4, and the absolute difference between the solubility parameters for the positioning adhesive and the fragranc...
