  • Patent number: 5464107
    Abstract: A hollow plastic container including a coextruded translucent plastic outer layer, an opaque plastic inner layer, and a viewing stripe of translucent or clear plastic material extending longitudinally in the inner layer. In one form the container viewing stripe is in the inner layer made of clear plastic material placed behind a thin translucent layer. In another form, the stripe is made of the same translucent plastic material as the outer layer. In a further form an additional inner layer is provided of translucent or clear plastic material. The hollow plastic container is made by coextruding a parison of at least two plastic layers to form an outer translucent plastic layer and an inner opaque plastic layer, and simultaneously coextruding a viewing stripe in the inner layer and extending longitudinally of the parison. This method allows production of a distinct viewing stripe of the same nominal outside color of an otherwide opaque plastic container.
