Patent ID: 8623404

Claim:
An oxybutynin medicine system, comprising: first and second opposing flexible plies forming a pouch comprising an enclosure; a seal, extending along at least a portion of a perimeter of the opposing plies with an enclosed cavity between the plies; first and second opposing tabs, formed by a portion of the respective first and second opposing plies which extend beyond the seal; an oxybutynin transdermal matrix or liquid reservoir system patch, disposed in the enclosed cavity between the first and second opposing plies, comprising: i) a backing layer; ii) oxybutynin; iii) an adhesive layer with an exposed perimeter, wherein the adhesive layer comprises an adhesive; and iv) a resilient release liner, removably attached over the adhesive layer so as to generate a spring force when displaced out of the flat configuration sufficient to overcome an adhesive force between the patch and one of the plies; the seal including a polyacrylonitrile copolymer resin; and the first and second opposing flexible plies having: i) a closed configuration in which a majority of the two plies are disposed in a planar layer; and ii) an open configuration in which at least a portion of the two plies are separated along the seal and pulled out of the planar layer and back across the planar layer to present the oxybutynin transdermal patch between the two plies.
