AI Technical Summary

Technical Problem

Plastic beverage containers deform under vertical compression, leading to deformation at the base or center, which causes tilting and permanent design changes, affecting stability and brand image, especially in lighter containers.

Method used

A deformable deformation section is introduced in the upper part of the container, specifically below the shoulder, allowing elastic deformation and compression, supported by rib geometry to stabilize the container.

Benefits of technology

The deformable section absorbs vertical forces, preventing permanent deformation and maintaining container integrity, ensuring stability and preventing tilting, even with low weights.

Abstract

A plastic container (1) for holding liquids, in particular beverages, comprising a bottom section (2), a base body (4) adjoining the bottom section (2) which forms a receiving volume for holding the liquid and which extends in a longitudinal direction (L) of the plastic container, a shoulder area (8) adjoining the base body in the longitudinal direction (L) in which a cross-section decreases in the longitudinal direction (L), and an opening area (10) adjoining the shoulder area (8) in the longitudinal direction (L) in which an opening is formed through which the liquid can be supplied to the container, wherein the shoulder area and the opening area are arranged in an upper section (A1) of the plastic container with respect to the longitudinal direction (L), characterized in thatthat the plastic container has a deformation section (6) in the upper section (A1) and in the longitudinal direction (L) below the opening section (10), in which the plastic container (1) is elastically deformable with respect to its longitudinal direction.
