A plastic bottle, made of polyethylene (PE), polypropylene (PP), or poly(ethylene terephthalate) (PET), blown with a very thin overall wall thickness within the range 0.1 to 0.3 mm, includes a triangular or polygonal cross-section, the bottle being preferably surrounded by a supporting jacket. The bottle can be blown with a uniform wall thickness and adequate strength without the need for reinforcing ribs via walls formed by pressing them against the surface of a blow mold which has been worked at least in some areas by etching, form-cutting or eroding, having features with heights of 0.05 to 0.15 mm.

Plastic container pack with a paperboard Jacket

A package for pourable substances like liquids or loose fine granulates includes an inner plastic container holding the substance to be packed and a cardboard envelop surrounding the plastic container, wherein the plastic container is a thin-walled hollow plastic body made by a blowing process. The envelope, when set up as a package, is at least locally in contact with the plastic container and is fitted with apertures facilitating its holding the plastic container. The hollow plastic body has at least two straight surfaces substantially forming one edge, in which a region of the associated side has a recess, and apertures in the cardboard envelope formed as a supporting case correspond to the recess in the edge region of the hollow plastic body to provide a handle.
