The plastic foil molding defines the front side of the blister package and the opaque cover foil defines the back side of the blister package, and the blister package additionally has in a certain region, which is formed outside of the region of the cavities of the plastic foil molding and is arranged overlapping at least the transparent region of the opaque cover foil, a semi-transparent function layer. The semi-transparent function layer is constituted such that the blister package has in the transparent region of the opaque cover foil upon viewing in incident light a first, visually recognizable color and upon viewing in transmitted light has a second, visually recognizable color. ## Claims ### Claim 1 A blister package comprising: a plastic foil molding furnished with cavities; and an opaque cover foil having at least one transparent region arranged outside of the cavities, wherein the plastic foil molding defines the front side of the blister package and the opaque cover foil defines the back side of the blister package, and wherein the blister package further comprises a semi-transparent function layer in a certain region, which is formed outside of the region of the cavities of the plastic foil molding and is arranged overlapping at least the transparent region of the opaque cover foil, and wherein the semi-transparent function layer is constituted such that the blister package has in the transparent region of the opaque cover foil, upon viewing in incident light a first, visually recognizable color and upon viewing in transmitted light, a second, visually recognizable color. ### Claim 2 (depends on 1) The blister package according to claim 1, wherein the semi-transparent function layer is formed on a carrier substrate and the carrier substrate furnished with the semi-transparent function layer is arranged between the plastic foil molding and the opaque cover foil. ### Claim 3 (depends on 1) The blister package according to claim 1, wherein the semi-transparent function layer is formed on a carrier substrate, and the opaque cover foil is arranged between the plastic foil molding and the carrier substrate furnished with the semi-transparent function layer. ### Claim 4 (depends on 1) The blister package according to claim 1, wherein the semi-transparent function layer is formed either directly on the plastic foil molding or within the plastic foil molding. ### Claim 5 (depends on 1) The blister package according to claim 1, wherein the semi-transparent function layer has a multilayer construction having two semi-transparent metallic layers and a dielectric layer arranged between the two semi-transparent metallic layers. ### Claim 6 (depends on 5) The blister package according to claim 5, wherein the two semi-transparent metallic layers are formed independently of each other from a metal and the metal respectively is chosen from the group consisting of Al, Ag, Ni, Cr, Cu, Au and an alloy of one or several of the hereinabove mentioned elements and the dielectric layer is a SiO2 layer, a ZnO layer, an Al2O3 layer, a TiO2 layer, a layer of a nitride or oxynitride of the elements Si, Zn, Al or Ti or a MgF2 layer or a nitrocellulose layer, obtainable by printing technology. ### Claim 7 (depends on 6) The blister package according to claim 6, wherein the two semi-transparent metallic layers are chosen from Al or Ag and the dielectric layer is a Si02 layer. ### Claim 8 (depends on 5) The blister package according to claim 5, wherein the blister package in the transparent region of the opaque cover foil upon viewing in incident light appears gold-colored and upon viewing in transmitted light has a blue color tone. ### Claim 9 (depends on 1) The blister package according to claim 1, wherein the semi-transparent function layer is obtainable by printing technology by means of an effect pigment composition. ### Claim 10 (depends on 1) The blister package according to claim 1, wherein the opaque cover foil is a metallic foil and the transparent region of the opaque cover foil is formed in the form of a recess in the opaque cover foil. ### Claim 11 (depends on 1) The blister package according to claim 1, wherein the blister package is a blister for pharmaceutical products. ### Claim 12 A method for manufacturing a blister package, the method comprising: providing a plastic foil molding furnished with cavities; providing an opaque cover foil having at least one transparent region; a covering the plastic foil molding furnished with the cavities with the cover foil such that the at least one transparent region is arranged outside of the cavities, the plastic foil molding defines the front side of the blister package and the opaque cover foil defines the back side of the blister package; and providing a semi-transparent function layer to the blister package in a certain region, which is formed outside of the region of the cavities of the plastic foil molding and is arranged overlapping at least the transparent region of the opaque cover foil, wherein the semi-transparent function layer is constituted such that the blister package has in the transparent region of the opaque cover foil, upon viewing in incident light, a first, visually recognizable color and upon viewing in transmitted light, a second, visually recognizable color.
