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 fabric and elastomeric material (referred to as a fabric trilayer) combined with a sealant may be applied in such a fashion so as to eliminate or minimize air entrapment in an elastomeric composite structure that forms a seal-sealing volume. The performance of the self-sealing volume is dramatically improved with this minimizing of air entrapment. Surprisingly and unexpectedly, this construction approach may be accomplished without significantly adding to the weight or thickness of the volume and without affecting the outer dimension of the self-sealing volume. Thus, a method and system for forming a self-sealing volume are described. The system includes an elastomeric composite structure comprising at least one layer of an elastomeric material derived from a neat (no solvent) elastomeric material that does not substantially react at room temperature.

A method for producing a container having a threaded wide neck, includes steps of: heating a preform having a polyester body, on which there is mounted a polyolefin sleeve positioned next to an area of the body corresponding to the wide neck of the container; introducing the heated preform, with the sleeve, into a mould having the footprint of the container, including a threaded area having the footprint of the wide neck; injecting a pressurised fluid into the preform in order to form a blank of the container including a lower portion including the wide neck with a thread formed in the sleeve and an upper portion above the wide neck; separating the upper portion from the lower portion that thus forms the container.
