Abstract
A packaging container is manufactured through fold forming, vacuum forming, injection molding or other processing to shape a plastically deformable, flexible material, comprising a tubular container body with two longitudinal edges which delimit between them a mainly flat container wall. In order to prevent deformation and/or cracking of the packaging container with normal handling of the side walls, the packaging container is provided with reinforcing elements formed through plastic deformation of the wall material in the region of the longitudinal edges. The reinforcing elements strengthen and stiffen the container and enable it to be conveniently gripped with the hand without the risk of the edges and/or the adjacent side walls being cracked or deformed.
Claims19
Packaging container, manufactured from a plastically deformable, flexible material, comprising:
- a tubular container body having at least two longitudinal edges which delimit between them a mainly flat side wall;
- and
- one or more reinforcing elements formed in the tubular container body in a corresponding number of regions near a corresponding number of the longitudinal edges, the reinforcing elements including one or more plastic deformations in the material which reinforce the corresponding number of longitudinal edges.
Packaging container manufactured from a plastically deformable material, comprising:
- a tubular container body having at least two longitudinal edges which delimit between them a mainly flat side wall of the container, the side wall being plastically deformed to form one or more reinforcing elements in a corresponding number of regions near a corresponding number of the longitudinal edges, the reinforcing elements being arranged along only a central part of the corresponding number of longitudinal edges.
