Method of isolating column loading and mitigating deformation of shaped metal vessels

Abstract

The present invention relates to a method of isolating column loading and mitigating deformation of shaped metal vessels, the method comprising forming a cylindrical metal tube into a shaped metal vessel, the shaped metal vessel comprising a sealed end, an open end, and an integral carry ring proximate the open end. Column load is isolated between the open end and the carry ring by supporting the shaped metal vessel by the carry ring. The shaped metal vessel is sealed with a closure, wherein deformation of the shaped metal vessel between the sealed end and the carry ring due to column load is minimized during application of the closure.

TECHNICAL FIELD OF THE INVENTION[0001]This invention relates to a method of isolating column loading and mitigating deformation of shaped metal vessels, the method comprising forming a cylindrical metal tube into a shaped metal vessel, the shaped metal vessel comprising a sealed end, an open end, and an integral carry ring proximate the open end. Column load is isolated between the open end and the carry ring by supporting the shaped metal vessel by the carry ring. The shaped metal vessel is sealed with a closure, wherein deformation of the shaped metal vessel between the sealed end and the carry ring due to column load is minimized during application of the closure.BACKGROUND OF THE INVENTION[0002]Before our invention product packaging, often formed from sheet metal or metal slugs had to be designed with wall thicknesses sufficient to avoid deformation or crushing when high column loads were applied to the top of the product packaging. Such high column loads can typically occur whi...

Benefits of technology

[0006]The shortcomings of the prior art are overcome and additional advantages are provided through the provision of a method of isolating column loading and mitigating deformation of shaped metal vessels, the method comprising forming a cylindrical metal tube into a shaped metal vessel, the shaped metal vessel comprising a sealed end, an open end, and an integral carry ring proximate the open end. Column load is isolated between the open end and the carry ring by supporting the shaped metal vessel by the carry ring. The shaped metal vessel is sealed with a closure, wherein deformation of the shaped metal vessel between the sealed end and the carry ring due to column load is minimized during application of the closure.

Problems solved by technology

Such high column loads can typically occur while the packaging closure is being applied thus sealing the product packaging on a filling line.

A shortcoming is that in designing packaging with thinner walls to support column loads more material is used in the product packaging, which raises the cost of the packaging.

Another shortcoming is that product packaging with thicker walls can be more difficult to shape and as such can limit the types and or kinds of possible functional and ornamental product packaging design options.
