Description

TECHNICAL FIELD OF THE INVENTION

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

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 while the packaging closure is being applied thus sealing the product packaging on a filling line. In this regard, often loading forces in excess of 175 pounds (lbs) can be applied to the top of the product packaging to apply and seal the packaging with a closure.
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.
There is a long felt need for a system and method to enable the high column load during filling and closure application to be isolated to the top portion of the product packaging and to avoid packaging deformation or crushing during the fill and or application of the closure to seal the beverage. In addition, there is a long felt need for a low cost metal package well suited for food and beverage applications, as well as a need for other types and kinds of packages that have thin and or weaker side wall constructions. In addition, there is a need to overcome the shortcomings mentioned above as well as to overcome other shortcomings. All of which gives rise to the present invention.

SUMMARY OF THE INVENTION

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.
Additional 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, and an open end. An outsert is applied around the open end of the shaped metal vessel, the outsert comprising a carry ring. 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.

DETAILED DESCRIPTION OF THE INVENTION

A. Shaped Metal Vessel
A shaped metal vessel is used in the present invention. Details of such shaped metal vessels can be found in the co-pending patent application entitled “SHAPED METAL VESSEL”, inventor John E. Adams et al., which was filed concurrently with the present application and is incorporated herein by reference in its entirety.
Turning now to the drawings in greater detail, it will be seen that in FIG. 1 there is illustrated one example of a system and method of isolating column loading and mitigating deformation of shaped vessels during fill and or closure application. In an exemplary embodiment, a plurality of shaped vessels 102A-C comprising outsert 106A-C can be formed by way of a plurality of cylindrical tubes and conveyed on a carrier 304. A carry ring can then be formed and or added to shaped vessel 102A-C. A carry ring support 302A-B can be used to support the shaped vessel during fill and or application of a closure 202. In this regard, a column load can be isolated between the carry ring and the open end of the shaped vessel 102C during shaped vessel 102 filling and or when the closure 202 is being applied.
For purposes of disclosure, column load also referred to as axially loading is defined as a load or force along or parallel to a concentric with a primary axis. In this regard, the primary axis is from the top open end to the bottom sealed end of the shaped vessel 102. In an exemplary embodiment, such a column load is typically present during fill and or when the closure is being applied to the shaped vessel 102 and when the shaped vessels are stacked on top of each other, such as when forming pallets of stacked product, store displays, storage of finished product, and or is present in other situations, as may be required and or desired in a particular embodiment.
In addition, for purposes of disclosure, a cylindrical tube is defined as the space enclosed by a cylindrical surface. As example, a soda or vessel can be referred to as a cylindrical tube. Furthermore, shaped vessel 102 can be referred to as a shaped metal vessel.
An advantage of isolating the column to the area between the carry ring and the open end of the shaped vessel 102A-C is that such column loading does not get applied to the area of the shaped vessel below the carry ring. As such, isolating the column load to the area between the carry ring and the open end of the shaped vessel effectuates the ability to manufacture a thinner walled shaped vessel, from metal or other materials, that might otherwise deform and or crush under high column loading. An economic advantage is that thinner walled vessels have less material and are less costly to manufacture. This is particularly true regarding metal vessels. A marketing and fabrication advantage is that the thinner walled vessels can be easier to shape and form, which effectuates the ability to create highly shaped vessels by numerous molding methods including blow molding, pressure ram, embossed, rolled, hydro formed, pneumatic formed, stamped halves, and or other methods, as may be required and or desired in a particular embodiment.
Referring to FIG. 2A-2C there is illustrated one example of product packaging also referred to as shaped vessel 102 or shaped metal vessel 102 comprising a column load-bearing outsert 106 having a carry ring 108.

In a plurality of exemplary embodiments the size of the shaped vessel can vary to accommodate shaped vessels that are small, medium, and large, as may be required and or desired in a particular embodiment. As example and not a limitation such dimensional aspect for a typical 500 milliliter (ml) vessel can be as follows. The total length of the shaped vessel 120 ‘A’ can be in the range of 230 mm to 280 mm, with a preferred length in the range of 251 mm.

In an exemplary embodiment where the shaped vessel 102 is fabricated from metal the thickness of the metal can be in the range of 0.0030 inch to 0.0250 inch.
B. Method of Making the Shaped Metal Vessel
Referring to FIG. 12 there is illustrated one example of a method of isolating column loading and mitigating deformation of shaped vessels 102 during closure 202 applications. In an exemplary embodiment, a cylindrical tube fabricated from metal, or other material can be molded and or formed into a shaped vessel 102. A carry ring can then be formed in the shaped vessel 102 proximate the open end of the shaped vessel 102. The contour vessel 102 can then supported by the carry ring to isolate the column load associated with the application of a closure 202 to the region between the open end and the carry ring. In this regard, isolating the column load to the open end of the shaped vessel 102 minimizes deformation of the shaped vessel 102 resultant from column loading during application of the closure 202. The shaped vessel 102 can then be sealed with the application of a closure 202. The method begins in block 1002.
In block 1002 a cylindrical tube is formed or otherwise shaped into a shaped vessel 102. In an exemplary embodiment, a cylindrical tube can be formed by injection molding, cupping, drawn and ironing (D&I), draw or re-draw (DRD) of sheet metal, impact extrusion of metal slugs, and or by other methods, as may be required and or desired in a particular embodiment. The cylindrical tube can be formed into a shaped vessel 102 by way of one or more or the following methods blow molding, pressure ram, embossing or de-embossing, die forming, trimming, shaping, hydro forming, pneumatic forming, rolled, necking or contouring, stamped halves, and or by other methods, as may be required and or desired in a particular embodiment.
In contrast to polyethylene terephthalate (PET) vessel forming, wherein the carry ring can be part of the injection molded preform and thus present prior to the step of molding, the method of the present invention forms the carry ring either as a separate step after the vessel is formed or during the forming of the vessel. This is considered an advantage in the present invention and is due in part to the fact that no preform exists and often the starting material is sheet metal or metal slug and as such molding or forming of the vessel is required prior to being able to add and or form a carry ring.
For purposes of disclosure embossed is defined as an embellishment such as indicia having a raised pattern on a surface. De-embossed is defined as an embellishment such as indicia having a sunken pattern on a surface. In the present invention such a surface can be the surface of the shaped vessel 102, the closure 202, and or other surfaces, as may be required and or desired in a particular embodiment.
Though advantageously the vessel 102 can create an iconic shaped vessel, the trade off can be a very thin walled vessel that can no longer support a column load that is generated while applying the closure to the vessel. In other embodiments, the cost of the shaped vessel 102 may be directly proportional to the amount of material such as aluminum or other material used to form the vessel. As an example and not a limitation, the more metal needed to make the vessel the higher the cost of the vessel. As such, it may be highly desirable to minimize vessel cost by making the shaped vessel with wall thicknesses as thin as possible to save material costs. In an exemplary embodiment, such shaped vessels 102 fabricated form metal or metal alloy can be shaped with wall thicknesses in the range of 0.0030 inch to 0.0250 inch.
In an exemplary embodiment, the shaped vessel 102 has a sealed end and an open end. In this regard, product can be put into the shaped vessel 102 and with a closure 202 seal the product into the shaped vessel 102. The method continues in block 1004.
In block 1004 a carry ring is formed proximate the open end of the shaped vessel 102. In this regard, a carry ring can be used to support the shaped vessel during fill and or application of the closure 202. Such application of a closure 202 can introduce a column load in the range of generally 30 lbs to 800 lbs depending on the type, kind, and manner that the closure is applied. In this regard, without supporting the shaped vessel 102 by the carry ring, such a column load could be sufficient to deform and or crush the thin walled shaped vessel 102.
In an exemplary embodiment, a carry ring can be formed into the wall of the shaped vessel and illustrated in FIGS. 7A-7B and or formed by other methods, as may be required and or desired in a particular embodiment. The method then continues in block 1006.
In block 1006 the column load is isolated between the carry ring and the open end of the vessel by supporting the shaped vessel with a carry ring support 302. As such, resultant from the shaped vessel 102 being supported by the carry ring support 302, the shaped vessel below the carry ring does not receive sufficient column load during application of the closure 202 to cause deformation and or crushing of the thin walled body portion of the shaped vessel 102. The method continues in block 1008.
In block 1008 the shaped vessel 102 is sealed with a closure 202. In an exemplary embodiment, for example and not a limitation, the shaped vessel can be filled with a product such as a refreshing COCA-COLA product prior to the shaped vessel being sealed. During such shaped vessel 102 sealing, depending on the closure type, for example a threaded closure, a crown type finish, metal or plastic closure, and or other types and kinds of closures, as may be required and or desired in a particular embodiment. Column load can range generally from 30 lbs to 800 lbs depending on the type, kind, and manner that the closure is applied.
An advantage with the present invention is that with the use of a carry ring, significantly higher column load forces can be used in the application of putting the closure onto the shaped vessel 102. In this regard, other types and kinds of closure 202 that currently cannot be used to seal vessels due to high column load damaging the vessel, can be used with the present invention due in part to the fact that the column load can be isolated between the carry ring, by way of the carry ring support 302 and the open end of the shaped vessel 102.
