Abstract

An apparatus and method of orienting and decorating container end closures is provided. More specifically, the present invention relates to apparatus and methods used to position container end closures in a predetermined orientation and then decorate a predetermined portion of the end closures.

Claims

1. A method of orienting and decorating an end closure, comprising:

providing a plurality of end closures which are adapted for interconnection to a neck of a container;

feeding at least one end closure into a first end of a guide assembly of an orientor;

engaging an orientation head of the orientor with an exterior surface of the end closure;

rotating the at least one end closure to align the at least one end closure in a predetermined orientation;

placing the end closure on a holder proximate to a second end of the guide assembly;

disengaging the orientation head from the end closure; and

decorating a predetermined portion of the exterior surface of the end closure with at least one of an image, a laser marking, a code, and a text message while the end closure is held by the holder.

2. The method of claim 1, wherein the guide assembly further comprises an inner rail interconnected to an outer rail, the inner and outer rails separated by a distance approximately equal to a height of the end closure.

3. The method of claim 1, wherein the guide assembly of the orientor has a substantially arcuate shape.

4. The method of claim 1, wherein the orientation head of the orientor is interconnected to a distal end of a spoke, and wherein a proximal end of the spoke is interconnected to a hub of the orientor.

5. The method of claim 4, wherein the spoke is operable to rotate the orientation head around a longitudinal axis of the spoke.

6. The method of claim 5, wherein the spoke is adapted to begin rotating the orientation head at a first point and stop rotating the orientation head at a second point as the hub of the orientor rotates axially.

7. The method of claim 6, wherein the first point is proximate to the first end of the guide assembly and the second point is between the first end and the second end of the guide assembly.

8. The method of claim 6, wherein the spoke further comprises a first gear adapted to engage a bevel gear of the hub, and wherein the first gear and the bevel gear are adapted to initiate rotation of the orientation head at the first point and stop rotation of the orientation head at the second point.

9. The method of claim 4, wherein the orientor is operable to rotate the end closure around a longitudinal axis of the spoke while the orientation head remains aligned with the predetermined orientation, and wherein the orientation head is operable to stop the rotation of the end closure when the end closure is aligned in the predetermined orientation.

10. The method of claim 1, wherein decorating a predetermined portion of the exterior surface of the end closure further comprises:

providing one or more printing blankets with a recess adapted to receive a pull tab which is interconnected to the exterior surface of the end closure;

removably affixing the printing blankets onto a drum of a printer;

forming the image on a print head;

applying ink to the image;

transferring the ink from the print head to a predetermined portion of the printing blankets; and

transferring the ink from the printing blankets to the predetermined portion of the exterior surface of the end closure.

11. An apparatus for receiving and orienting an end closure which is adapted for interconnection to a neck of a container, comprising:

an arcuate guide assembly comprising a first end and a second end, the first end adapted to receive an end closure and the second end adapted to release the end closure;

a hub operable to rotate proximate to the arcuate guide assembly at a predetermined rate;

a plurality of spokes radially interconnected to the hub; and

an orientation head interconnected to a distal end of each spoke, the orientation head adapted to engage an exterior surface portion of the end closure at the first end of the arcuate guide assembly and align the end closure to a predetermined orientation as the orientation head and the end closure move from the first end to the second end of the arcuate guide assembly.

12. The apparatus of claim 11, wherein the arcuate guide assembly further comprises an inner portion spaced from an outer portion, wherein at least a portion of the exterior surface portion of the end closure contacts the inner portion and at least a portion of an interior surface portion of the end closure contacts the outer portion.

13. The apparatus of claim 11, wherein the orientation head further comprises a body portion interconnected to the spoke, a face portion comprising a substantially planar surface orientated in a plane generally perpendicular to the body portion, and a pocket formed in a portion of the face portion, the pocket comprising a geometric profile adapted to receive a pull tab interconnected to the exterior surface portion of the end closure.

14. The apparatus of claim 11, wherein the orientation head engages the exterior surface of the end closure and rotates the end closure as the end closure travels between the first end and second end of the arcuate guide assembly.

15. The apparatus of claim 14, further comprising:

a bevel gear operably engaged to the hub, the bevel gear comprising a face portion oriented substantially perpendicular to an axis of rotation of the hub, and teeth formed on a portion of an annulus of the face portion; and

a pinion gear interconnected to the spoke, wherein teeth of the pinion gear engage the teeth formed on the bevel gear to rotate at least a portion of the spoke and the orientation head.

16. The apparatus of claim 11, wherein the apparatus is operable to rotate the end closure as the orientation head and the end closure move between the first end and second end of the arcuate guide assembly.

17. A method of orienting a metallic end closure, comprising:

providing an orientor comprising;

an arcuate guide assembly including a first end, a second end, and a means for engaging and supporting an end closure;

a hub operable to rotate at a predetermined rate;

a plurality of spokes extending radially from the hub; and

an orientation head interconnected to the distal end of each spoke, the orientation head having a face portion adapted to engage an exterior surface portion of an end closure, wherein each of the plurality of spokes are adapted to move the face portion of the orientation head interconnected thereto from the first end to the second end of the arcuate guide assembly;

receiving an end closure at the first end of the arcuate guide assembly, wherein a pull tab interconnected to the exterior surface portion of the end closure is positioned proximate to a face portion of one of the orientation heads;

rotating the hub, wherein the face portion of the orientation head engages the end closure and moves the end closure from the first end to the second end of the arcuate guide assembly; and

rotating the end closure around a longitudinal axis of the spoke associated with the orientation head, wherein the end closure and the pull tab are aligned in a predetermined orientation when the end closure exits the second end of the arcuate guide assembly.

18. The method of claim 17, wherein the orientor further comprises:

a bevel gear interconnected to the hub, the bevel gear comprising a predetermined number of teeth formed on a portion of the bevel gear; and

a pinion gear interconnected to each of the plurality of spokes, wherein when the hub rotates, the teeth of the pinion gears engage the teeth of the bevel gear and at least a portion of each spoke and the orientation head interconnected thereto rotates.

19. The method of claim 17, wherein the spoke is biased in a radially extended position, and wherein the face portion of the orientation head applies a force to the exterior surface portion of the end closure when the end closure is engaged to the face portion of the orientation head.

20. The method of claim 17, further comprising disengaging the orientation head from the end closure after the end closure is aligned in a predetermined orientation.
