Systems and Related Methods for Manufacturing Ring Pull Bottle Crown

Abstract

Equipment and related methods for manufacturing ring pull crowns are disclosed herein. In one embodiment, a method of manufacturing a ring pull crown comprises forming a plurality of crown bodies from a first source material, and forming a plurality of pull ring and tab assemblies from a second source material. In addition, such a method may comprise forming a plurality of ring pull crowns by combining each crown body of the plurality of crown bodies with a corresponding pull ring and tab assembly from the plurality of pull ring and tab assemblies. Also, such method may also comprise forming a circumferential skirt that descends below a top of each ring pull crown, and removing the plurality of ring pull crowns from the first source material.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This non-provisional application claims the benefit of U.S. Provisional Application No. 61 / 986,521 under 35 U.S.C. §119(e). In addition, the disclosures of U.S. Pat. Nos. 8,061,544, 8,276,773, 8,365,940, 8,608,006, and 8,944,264, and U.S. patent application Ser. Nos. 14 / 098,208, 14 / 244,571, and 14 / 605,704, all by the same inventor, are incorporated herein by reference for all purposes.BACKGROUND[0002]1. Field of the Disclosure[0003]This invention relates in general to sheet metal manufacturing processes, and more particularly to systems and related methods for manufacturing ring pull bottle crowns.[0004]2. Background[0005]A beverage bottle that opens manually with relative ease, without the use of a bottle opener, has been a long-felt need for beverage providers. Bottle caps must be tightly secured to the bottle opening to prevent spillage of the contents, loss of pressure (in the case of pressurized or carbonated beverages) and to mainta...

AI Technical Summary

Benefits of technology

The patent is about a new system and method for making ring pull bottle crowns. The system has the advantage of being able to make the ring, tab, rivet, and cap using a single machine. The pull ring can also be produced in a separate color from the crown body. Another advantage is that printed material can appear on the crown surface, rivet, and corrugation. This invention makes it easier and more efficient to produce these rings for bottles.

Problems solved by technology

The tight seal makes it difficult to open a bottle by hand.

Such ring pull crowns, however, are notoriously difficult to open because they require the exertion of an uncomfortable amount of force to break the seal and then pull the tab back (tearing the metal) to remove the cap.

The MAXICROWN® provides a pull ring disposed along the side of the neck of the bottle as an extension of the crown and thus is problematic for use with standard angle-crimping bottle capping machines.
