Abstract

An end closure for food and beverage containers is provided. The end closure comprises a contoured neck feature configured for increased strength and alignment with a user's lips. The contoured neck may further comprise features increasing container buckling strength and reducing user spillage.

Description

The present application is a continuation-in-part of U.S. Design patent application No. 29/430,744, filed Aug. 29, 2012, the entire disclosure of which is hereby incorporated herein by reference in its entirety.

FIELD OF THE INVENTION

The present invention relates generally to beverage container necks. More specifically, the present invention relates to beverage container necks with contoured neck features configured for increased buckling strength and alignment with a user's lips.

BACKGROUND

Containers, and more specifically metallic beverage containers, are typically manufactured by interconnecting a beverage container body with a beverage container end closure. It is generally known to provide beverage container necks which interconnect to beverage container end closures. The beverage container neck typically reduces and then expands the beverage container body diameter before engaging with the end closure. Conventional container necks include a shoulder portion, which reduces the body diameter to a waist diameter, and an upper portion that expands the neck portion to engage the end closure through a peripheral curl and chuck wall. Conventional beverage container necks disclose geometries of moderate contours, that is, moderate reductions in waist diameter and moderate expansions to an end closure. Conventional designs do not feature substantially parallel neck and chuck wall portions. As such, these designs traditionally retain beverage product within a geometric gap between the chuck wall and the neck. Also, these designs are of limited strength, for example limited in buckling strength when stacked upon one another. Furthermore, conventional cans provide a less satisfying drinking experience, as demonstrated by, for example, increased spillage caused by inadequate contact between a user's lips and the can's neck area.
Some efforts to improve the drinking experience of beverage containers, such as minimizing spillage, include U.S. Pat. No. 3,704,805 to Sheafe and U.S. Patent Application No. 2006/0131255 to Blondeel. Sheafe discloses a beverage container with a removable panel portion formed by a peripheral score line. The end panel has a concave portion extending into a score line and on both sides of a removable panel portion to enable an upper lip of a person drinking from the container to extend into the concave portion. The concave portion of the end panel is said to facilitate drinking from the container. Blondeel discloses a detachable element to engage a can's opening area. Each of Sheafe and Blondeel, however, fail to teach several novel features of the present invention, including an inclined shoulder wall extending inwardly and upwardly to a contoured neck portion, the contoured neck portion extending upwardly and outwardly to the upper end of the can. Sheafe and Blondeel are each incorporated by reference in their entireties for all purposes.
Some patents attempt to improve beverage container drinkability and minimize spillage by creating one or more openings. These patents include U.S. Pat. No. 7,513,383 to Hwang and U.S. Pat. No. 4,289,251 to Maliszewski, which are incorporated herein by reference in their entireties. Hwang discloses an opening device for a can, with distinct first and second opening portions so that the fluid may flow more consistently from the can. Maliszewski discloses a container end closure with a first score line defining a first displaceable panel portion and second score line defining a second displaceable panel portion. Neither of Hwang nor Maliszewski, however, disclose several novel features of the present invention, including an inclined shoulder wall extending inwardly and upwardly to a contoured neck portion, the contoured neck portion extending upwardly and outwardly to the upper end of the can.
Some efforts have been made to adjust or offset the countersink portion of beverage containers for increased functionality, cost, and/or manufacturability. These efforts include U.S. Patent Application Publication No. 2012/0125935 to Nguyen (“Nguyen I”) and U.S. Pat. No. 7,100,789 to Nguyen (“Nguyen II”). Nguyen I features a metallic container end closure with an outwardly-oriented countersink which enables the container to withstand significant internal pressures yet save material costs. Nguyen II discloses a beverage container end closure that utilizes less material and has a chuck wall with improved buckle strength attributed to an inwardly oriented concave arch. However, each of Nguyen I and Nguyen II fail to teach several novel features of the present invention, including an inclined shoulder wail extending inwardly and upwardly to a contoured neck portion positioned at a radius at least 0.07 inches reduced from the can diameter, the contoured neck portion extending upwardly and outwardly to the upper end of the can. Nguyen I and Nguyen II are each incorporated by reference in their entireties for all purposes. Container end closures that employ other unique geometries are disclosed in U.S. Pat. Nos. 7,506,779; 5,685,189; 6,126,034; 6,460,723; 6,968,724 and U.S. Patent Application Publication Nos. 2002/015807 and 2005/0029269, which are each incorporated herein by reference.
For purposes of further disclosure, the following references generally related to container end panels are hereby incorporated by reference in their entireties: U.S. Patent Application Publication No. 2012/0031056 to Chastem; Japanese Patent Publication No. JP2002145263 to Yoshihiko; and Japanese Patent Publication No. JP2000159229 to Yoshihiko

SUMMARY OF THE INVENTION

Accordingly, the present invention contemplates a novel system, device, and methods for providing a food and beverage container neck with contoured neck features configured to reduce retained product, increase container strength, and provide an enhanced drinking experience. More specifically, the contoured neck feature reduces retained product by minimizing the gap between the container neck and the chuck wall of an end closure, increases strength such as stacking, compressive strength or buckling strength, and enables a user to engage the contoured neck feature with minimal spill-over by presenting an improved alignment with a user's lips.
