Abstract:
A product containment and delivery system for a comparatively viscous product, said containment and delivery system comprising in combination: (i) a comparatively high viscosity product having a viscosity of at least about 10,000 cps, said high viscosity product being a liquid or semi-liquid; and (ii) a flexible resiliently deformable, multi-layered plastic container having an inner polymer layer and an outer polymer layer, said inner polymer layer defining an inner surface of said container and said outer polymer layer defining a flexible outer surface of said container; characterized in that said inner layer comprises a material which is selected from the group consisting of polyesters, thermoplastic cellulosic, polycarbonates, polymethylmethacrylates, polyvinylchlorides, polyvinylidene chlorides, ethylene vinyl acetates with vinyl acetate content of at lest about 7.5%, ethylene vinyl alcohol copolymers, ionomer resins having at least 10% carboxylic acid groups neutralized by an alkali metal ion, and mixtures thereof, said inner polymer layer is bonded to said outer polymer layer, and said system has a residual level of less than 5% of said product.
