Container body and its method of making
The present invention relates to a method of making a container body ( 8 ), comprising the steps of: i) providing a round container body ( 8 ); ii) forming at least one circumferential bead ( 2 ) in the container body ( 8 ); and iii) axially compressing the container body ( 8 ) to kink and axially close the kinked bead ( 10 ), and to such container body ( 8 ) and container comprising same.
1. A method of making a container body, comprising the steps of:
i) providing a round container body;
ii) forming at least one circumferential bead in the container body;
iii) axially compressing the container body to kink and axially close the bead, thereby creating a kinked bead; and
iv) radially compressing the kinked bead, thereby creating a radially compressed, kinked bead.
2. The method according to claim 1 , wherein the bead has a symmetrical shape and in step iii) kinking is initiated at one side of the symmetrical bead.
3. The method according to claim 1 , wherein the bead has an asymmetrical shape such that the kinking force is different at both bead sides.
4. The method according to claim 1 , wherein the radially compressed, kinked bead is is caused to extend radially outwardly of an outer surface of the container body by radial expansion of the container body and is then radially compressed by a compression tool.
5. The method according to claim 1 , wherein the kinked bead is radially inwardly compressed to create the radially compressed, kinked bead.
6. The method according to claim 1 , further comprising the step of providing printed information on the container body, which printed information is separated from a container body section in which the circumferential bead is to be formed.
7. The method according to claim 1 , wherein the bead has the form of a serpentining bead, a wavy bead, and/or an ornamental bead.
8. A container comprising a container body provided with at least one circumferential axially closed and kinked bead,
wherein the kinked bead is radially compressed.
9. The container according to claim 8 , wherein the bead extends radially outwardly or inwardly from the container body wall.
10. The container according to claim 8 , further comprising printed information at both sides of the kinked bead.
11. A container body obtainable by the method according to claim 1 .
12. The container according to claim 8 , wherein the bead extends radially outwardly or inwardly from a container body wall of the container body.
13. The method according to claim 2 , wherein the bead has an asymmetrical shape such that the kinking force is different at both bead sides.
14. The method according to claim 6 , wherein the printed information is present at both sides of the closed and kinked bead and is provided in a flushing manner.
15. The container according to claim 10 , wherein the printed information at both sides is printed in a flushing manner.
