Abstract

The invention provides a container formed of a common one-piece multilayer thermoplastic substrate. The container wall has an outer layer and an adjacent underlying layer. And the underlying layer hasa colorant visible through the outer layer. The colorant in the underlying layer can be one or more pigments and or one or more dyes.

Description

technical field [0001] The present invention relates to a container formed from a one-piece multilayer thermoplastic substrate, the lower layer having a colorant visible through the outer layer. Background technique [0002] Blow molded containers are widely used as the preferred packaging for pourable consumer products. Such containers are typically formed from a single layer of material and have a uniform visual appearance. For example, the container may be transparent or translucent or opaque and have a single color. Decoration may be provided in the form of a label. Labels such as direct object printing, pressure sensitive labels, heat transfer labels, shrink sleeve labels, and in-mold labels are commonly used. [0003] A more refined visual appearance of the container can be provided by the use of colorants in the component materials of the container. Colorants such as dyes and pigments are commonly used. To enhance the visual effect of the colorant in the containe...
