Abstract
A three-dimensional structure of concentric rings forming a container of plastic material. A plurality of concentric ring-shaped wall elements adjoin each other to form an inner surface of the container. Adjacently adjoining wall elements are connected and inclined with respect to each other. The wall elements are connected to each other with a ring-shaped area of reduced wall thickness, forming a film hinge. The wall elements are inclined so that they can be turned down over adjoining elements to collapse the container.
Claims5
A three-dimensional structure of concentric rings forming a collapsible container of plastic material with an inner surface (1) and a plurality of adjoining concentric, ring-shaped wall elements, wherein respectively adjoining said wall elements are positioned at an angle of inclination with respect to each other, the collapsible container comprising:
- inclined wall elements (20, 21, 22) of said wall elements each respectively disposed between two generally vertical wall elements (30, 31, 32) of said wall elements, each said adjoining wall elements (20, 30;
- 21, 31;
- 22, 32) respectively connected with respect to each other with a ring-shaped area (40-45) of reduced wall thickness, whereby said inclined wall elements (20, 21, 22) can be turned down over adjoining said vertical wall elements (30, 31, 32) and wherein a corresponding said angle of inclination of each of said inclined wall elements (20, 21, 22) increases as a mean diameter of each said inclined wall element (20, 21, 22) decreases.
