Abstract

A closure unit includes a closure head that closes a container by applying a closure onto a container opening thereof, a grouper that brings closed containers close together to form a bundle of closed containers, and an adhesive applicator that applies adhesive to a circumferential side wall of a container.

First claim

Having described the invention, and numerous embodiments thereof, what is claimed as new and secured by Letters Patent is:

1. An apparatus comprising:
a closure unit comprising:
a container-delivery element,
a transport element defining a transport route,
a closure head, and
a first adhesive applicator, and
a grouper,

wherein said container-delivery element is structured and configured to deliver a first unclosed container to said transport element,
wherein said closure head is structured and configured to permit a closure to be screwed onto a container opening of the first container along a portion of the transport route to close the first container,
wherein said first adhesive-applicator is structured and configured to apply a first adhesive-spot to a desired location on a circumferential side wall of said first container at a position along the transport route,
wherein said closure unit is structured and configured to provide controlled rotation of said first container about a vertically-oriented container axis thereof to position the first container to receive the first adhesive spot at the desired location on the circumferential side wall of the first container, and
wherein said grouper is structured and configured to bring said first container and a second container together to promote adhesive engagement between said containers, thereby forming a bundle of at least said first and second containers.

2. The apparatus of claim 1 , wherein said closure head causes said first container rotation of said container.

3. The apparatus of claim 1 , wherein said controlled rotation of said first container takes place through rotation of a surface with which said first container is in contact.

4. The apparatus of claim 1 , wherein said controlled rotation of said first container takes place through rotation of a surface upon which said first container stands.

5. The apparatus of claim 1 , further comprising a sensor, wherein said sensor is configured to detect an actual rotation position of said first container.

6. The apparatus of claim 1 , further comprising a rotation-angle sensor for determining an extent to which said first container has rotated.

7. The apparatus of claim 1 , wherein said closure unit comprises said transport element for transport of said first container from said container delivery element to a container outlet.

8. The apparatus of claim 7 , wherein said transport element is configured to rotate continuously.

9. The apparatus of claim 7 , wherein said transport element is configured to rotate intermittently.

10. The apparatus of claim 7 , wherein said transport element comprises a rotor configured to rotate about a vertical machine axis.

11. The apparatus of claim 1 , further comprising a compacter on which containers are pressed together to promote adhesive connection between said containers.

12. The apparatus of claim 11 , further comprising a hardener disposed at said compacter.

13. The apparatus of claim 1 , further comprising a second adhesive-applicator, wherein said second adhesive-applicator applies a second adhesive-spot to said circumferential side wall of said first container, wherein said first and second adhesive-spots are at different circumferential angles.

14. The apparatus of claim 13 , wherein said first and second adhesive-spots are offset by ninety degrees.

15. The apparatus of claim 13 , wherein said first adhesive-applicator is configured to apply said first adhesive-spot prior to said controlled rotation and said second adhesive-applicator is configured to apply said second adhesive-spot after said controlled rotation.

16. The apparatus of claim 1 , wherein said first adhesive-applicator is configured to apply said first adhesive-spot prior to said controlled rotation.

17. The apparatus of claim 1 , wherein said first adhesive-applicator is configured to apply said first adhesive-spot after said controlled rotation.

18. A method for forming a bundle of containers, wherein the method comprises:
delivering filled containers to a closure unit, said containers being at least one of labeled and printed upon before being delivered to the closure unit,
providing closures for closing each of said containers at said closure unit,
closing each of said containers with a corresponding closure at said closure unit,
rotating each of said containers about a vertical axis thereof within said closure unit to orient said containers,
applying adhesive onto circumferential side walls of said rotated and oriented containers at said closure unit,
after having applied adhesive onto said circumferential side walls, removing said closed containers from said closure unit and bringing said closed containers together to promote adhesive engagement between said closed containers, and
compacting said adhesively engaged closed containers to form said bundle.

19. The method of claim 18 , wherein rotating each of said containers about a vertical axis thereof comprises using a closure head to rotate a container.

20. The method of claim 18 , further comprising causing rotating each of said containers about a vertical axis thereof, applying adhesive onto said circumferential side walls of said containers, and closing each of said containers with a corresponding closure all occur in sequence within a transport route inside said closure unit.
