Provided is a method for manufacturing a preform (1). The method includes injecting into a cavity of a mold through the gate: (i) a first colored resin (R1) for a first predetermined time period, and (ii) a second colored resin (R2), having a color different from that of the first colored resin, for a second predetermined time period.

Blow molded articles having a predetermined feature incorporated into the wall provided by variations in the thickness of the wall of the article corresponding to a predetermined pattern etched into the preform from which the article was formed. Also, etched preforms for making blow molded articles and methods for making such preforms and articles.

Method of making a blow molded article from a preform including: a) providing a preform of a thermoplastic material having a plurality of effect structures each having an effect surface having a normal with an orientation, the preform having a body with one or more walls and an opening, wherein at least a portion of the one or more walls of the preform has a three-dimensional pattern of cavities and/or protrusions thereon; and b) blow molding the preform to form a blow molded article, wherein the step of blow molding the preform changes the orientation of the normal of at least some of the effect surfaces of the effect structures to create a visual effect in at least one wall of the blow molded article.

The present invention relates to a multilayer container preform and a multilayer container, said preform or container comprising a base, a body and a neck finish, said base and body comprising an outer layer defining an exterior surface, an inner layer defining an interior surface and interior space, and an intermediate layer disposed between the outer layer and the inner layer, said outer layer and said inner layer comprising a primary material selected from the group consisting of a 2,5-furandicarboxylate polyester or co-polyester or a blend thereof, and said intermediate layer comprising a secondary material different from the primary material, but compatible with the primary material. The invention relates to methods of producing such a multilayer container preform and multilayer container

A blow molded article having a body portion that includes one or more walls surrounding an interior space. The one or more walls have an article inner surface, an article outer surface, and a wall thickness. At least a portion of the one or more walls includes one or more effect structures each having an effect surface normal having an orientation. Further there is a first region including a plurality of first effect structures having a first Average Normal Orientation, a second region including a plurality of second effect structures having a second Average Normal Orientation which is different from the first Average Normal Orientation, and a visual effect resulting from the difference between the first Average Normal Orientation of the effect structures in the first region and the second Average Normal Orientation of the effect structures in the second region.

A blow molded monolayer article. The article has a hollow body defined by a wall. The wall has one or more regions comprising a first composition and one or more regions formed by a second composition.

A plastic container including a container body (1) made from a colored olefin resin and a decorative layer (3) laminated on the outer surface thereof. The decorative layer includes a transparent adhesive resin layer (3b), a transparent polyester resin layer (3a) which is the outer surface layer, and an intermediate gradation layer (3c) including a portion of which the thickness gradually varies in the direction of height of the container. The gradation layer is formed of a transparent polyester resin blended with a coloring agent. The thickness of the container body varies in response to a change in the thickness of the gradation layer in a manner such that the thickness of the container body portion which is the total thickness of the thickness of the container body and the thickness of the decorative layer is not varied by the presence of the gradation layer.

A method includes injection molding a preform using a two phase injection system having a first phase in which a material is injected into the preform and a second phase in which the material is injected into the preform. The preform is disposed in a mold. The preform is blow molded into an intermediate article. The intermediate article is trimmed to form a finished container. The first phase includes injecting a material into the preform to form a single layer of the preform and the second phase includes injecting the material to form inner and outer layers and an intermediate layer between the inner and outer layers. The inner and outer layers include the material and the intermediate layer includes at least one additive. Finished containers are disclosed.
