The invention relates to a container made from thermoplastic polymer with at least one inner reinforcing rib in a container wall, wherein the reinforcing rib is formed by at least one linear groove track in a container outer wall, the groove track extends over a length on the container outer wall, the groove track is formed by a multiplicity of depressions in the container outer wall, said depressions being arranged at a distance from one another, and wherein material bridges are provided between each of the depressions, said material bridges each having a smaller depth than the depressions. The invention furthermore relates to a method for producing such a container by extrusion blow molding or thermoforming.

In a synthetic resin blow molded bottle, reduced pressure absorbing panel portions and column portions are formed alternately in the circumferential direction. Each column portion has a diameter that gradually increases downward and that remains substantially constant vertically. Each reduced pressure absorbing panel portion includes a pair of panel side edge portions, which is bent to the inner side from the adjacent column portions, a panel surface portion, which connects the pair of panel side edge portions, and a panel lower edge portion, which is bent to the outer side from a lower end edge of the panel surface portion. The panel surface portion of each reduced pressure absorbing panel portion includes a panel upper-side surface portion, whose diameter gradually increases downward, and a panel lower-side surface portion, which connects the panel upper-side surface portion and the panel lower edge portion and which has a substantially constant diameter vertically.

The present invention is directed to a process for making a low coefficient of friction (COF) high gloss polyolefin bottle by the following: a) adding a high gloss metallocene polyethylene during a manufacturing process on the outer layer of a container; b) adding a slip agent on the outer layer of the container wherein the container has a gloss range greater than 60 gloss units with a coefficient of friction of less than 0.25.
