Filed:

Nov 27, 2002

Appl. No.:

10/306921

Inventors:

Christopher J. Olson - Superior CO
Harold Cook, Jr. - Evergreen CO

Assignee:

Omnitech International, Inc. - Golden CO

International Classification:

B21D 5144

US Classification:

413 12, 413 14, 413 16, 413 17, 220266, 220270, 2203091

Abstract:

The disclosed invention describes a container end that can be easily opened and does not rely on a conventional metal tab, riveted onto the end, thereby avoiding the problems and the cost associated with such a tab. The invention utilizes a traditional container end shell with a separate and distinct piece that is formed independently and is inserted into a countersink which is placed on the outer surface of the container end shell. The removal of this separate piece exerts a force or causes a change in the properties of the container wall in the countersink area, initiating and proliferating a discontinuity in the container wall, thereby creating an opening in the container. This change in the properties of the container wall can be mechanical, chemical, thermal or any other modality, which has the ability to influence the integrity of the container wall.

US Classification:

72 94, 7240503

Abstract:

Apparatus and method for forming (e. g. die necking) open ends of open-ended metal container bodies. An exemplary embodiment provides a number of movable holders for container bodies that move the container bodies along a path extending through the apparatus. A motor advances the holders and container bodies along the path in steps with pauses between each step. Each step advances one or more container bodies (and preferably two or more). One or more groups of work stations positioned adjacent to the path provides tool sets for carrying out a forming operation on one (and preferably two or more) container bodies simultaneously. Individual container bodies, or more preferably groups of two or more, are subjected to one or more forming operations during passage along the path (preferably the periphery of one or more star wheels).

Inventors:

Christopher Olson - Superior CO, US

Assignee:

OMNITECH INTERNATIONAL, INC - Golden CO

International Classification:

B65B 7/28

US Classification:

215044000

Abstract:

Disclosed is an unique reclosable metal bottle in which a trim portion of the neck can be reused and mounted on the neck as a collar, or a separate collar provided, that has the structural rigidity necessary to form threads or lugs for recloseability. Thin wall metal bottles, having thicknesses on the order of thin wall metal cans currently in use, can be made using this process with minimal material waste since the trim neck portion is reused as a threaded collar. Structural rigidity and strength can be added by using fillers to backfill the indentations of the threads in the collar. Threads or lugs can be used, including pressure release lugs, that add both safety and convenience. Since the reclosable metal bottle is an all-metal container, the bottle can be recycled without introducing contaminants.

Appl. No.:

11/843265

Inventors:

Christopher Olson - Superior CO, US
Edmund Gillest - Arvada CO, US

International Classification:

B65D 1/02
B65B 7/28

US Classification:

215040000, 053488000

Abstract:

Disclosed is a metal bottle seal that is disposed on the curl of the metal bottle. The bottle seal may be held in place by crimping of the curl. In addition, adhesive may be used to hold the bottle seal on the curl. Adhesives can be used that fill discontinuities that may exist in the curl as a result of substantial drawing and ironing of the metal. Further, the metal bottle seal can be made of a material or laminated with a material that is soft enough to fill the discontinuities. The seal can be preformed as a continuous annulus for easy application to the top of the metal bottle. The metal bottle seal can also be used in conjunction with a cap seal to ensure an adequate and reliable seal.
