A system of the present invention for applying a substance to an applied area includes a patch (11), as well as apparatus (12, 14, 16, 18 and 21) and methods for making the same. The patch includes backing material (52) and a tri-laminate (54), with a dose of medication sealed therebetween in reservoir (62). To facilitate and increase transdermal and/or topical application of the medication to the applied area, such as the skin of a user, the tri-laminate includes a layer material (68) having at least one opening therein (64), which permits the medication to flow through each opening without tearing or ripping the layer of material covering the reservoir.
