Description
[0001] 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
[0002] 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
[0003] 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.
[0004] 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.
[0005] 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.
[0006] 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.
[0007] 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

SUMMARY OF THE INVENTION
[0008] 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.

is oriented at a different angle than the inclined shoulder wall at
another portion of the container neck. More specifically, a first
neck portion has an inclined shoulder wall with radius R.sub.1 and
extending inwardly and upwardly at a first neck angle A.sub.3 to
shoulder wall radius R.sub.7. On an opposing side, the contoured
neck has an inclined shoulder wall with shoulder radius R.sub.1 and
extending inwardly and upwardly at contoured neck angle A.sub.1
which is distinct from the first neck angle A3. The inclined
shoulder wall extends upwardly to shoulder wall radius R.sub.6. As
illustrated in FIG. 4A, a contoured neck profile radius R.sub.2
comprises a radius around the center axis of the container of
between approximately 30 and 180 degrees, and has a distinct
geometric profile when compared to a contoured neck profile on
another portion of the container. More preferably, R.sub.2
comprises a radius of between approximately 30 and 120 degrees. In
a preferred embodiment, R.sub.2 comprises a radius of 90 degrees.
In various embodiments, standard neck profile radius R.sub.5
comprises a radius of between approximately 180 and 330 degrees.
More preferably, R.sub.5 comprises a radius of between
approximately 240 and 330 degrees. In a preferred embodiment,
R.sub.5 comprises a radius of 270 degrees.
[0047] In the embodiment of FIG. 4E, contoured neck angle A.sub.1
comprises an angle of 38 degrees and expansion neck angle A.sub.2
comprises an angle of 14 degrees. The contoured neck with end
closure 10 portion is generally positioned opposite the primary
opening area 32 and score 30.
[0048] The standard neck of container 2 is shown as FIG. 4D
generally comprising peripheral curl 16, countersink 18, inner
panel wall 20, standard neck angle A.sub.3 and chuck wall 24 with
chuck wall upper end 28 and chuck wall lower end 26. Note that in
the portion of the container 2 configured with a standard neck as
depicted in detail in FIG. 4D, the portion of the container neck 4
that is opposite the chuck wall 24 is not parallel, and distinct
from the embodiment shown in FIG. 4E.
[0049] More specifically, a novel contoured neck of container 2 is
shown as FIG. 4E, generally comprising a peripheral curl 16, a
countersink 18, an inner panel wall 20, a contoured neck angle
A.sub.1 and chuck wall 24 with chuck wall upper end 28 and chuck
wall lower end 26. Inclined shoulder wall 34 extends upward and
inwardly, and transitions to an inclined shoulder radius R.sub.6.
Note that in the embodiment depicted in detail in FIG. 4E, the
portion of the container neck 4 that is opposite the chuck wall 24
is substantially parallel from the uppermost portion of the chuck
wall to substantially a lowermost portion of the countersink. As
appreciated by one skilled in the art, variations of the distance
between the chuck wall and container neck opposite the chuck wall
may be common based on design parameters. FIGS. 5A-C depict a
beverage container 2 with contoured neck 4 wherein the contoured
neck is a full contour and contoured to the end closure shape. FIG.
5A is a top plan view of container 2 and depicts end closure 10
which generally comprises a tab 12, central panel 14 and peripheral
curl 16. FIG. 5B is a front elevation view of container 2 with
identified detail area A. FIG. 5C is a detail area A of FIG. 5B and
generally depicting a unique and novel cross-sectional upper neck
region which is substantially a mirror image of the profile of the
end closure extending from the peripheral curl to the countersink.
In various embodiments, contoured neck lower radius R.sub.3
comprises a radius of between approximately 0.04 and 0.30 inches.
More preferably, R.sub.3 comprises a radius of between
approximately 0.04 and 0.10 inches. In a preferred embodiment,
R.sub.3 comprises a radius of 0.052 inches. In various embodiments,
contoured neck lower radius R.sub.4 comprises a radius of between
approximately 0.04 and 0.30 inches. More preferably, R.sub.4
comprises a radius of between approximately 0.04 and 0.10 inches.
In a preferred embodiment, R.sub.4 comprises a radius of 0.043
inches. In the embodiment of FIGS. 5A-C, the portion of the
container neck 4 that is opposite the chuck wall 24 is
substantially parallel and substantially in contact with the chuck
wall 24.
[0050] FIG. 6 depicts a partial front elevation view of an
alternative embodiment of a beverage container 2 comprising end
closure 10 and a non-concentric shoulder and neck portion, wherein
one portion of the inclined shoulder wall is oriented at a
different angle than the inclined shoulder wall at another portion
of the container. More specifically, a first neck portion 4 has an
inclined shoulder wall with radius R.sub.1 and extending inwardly
and upwardly at a first neck angle A.sub.3 to standard neck
inclined shoulder wall radius R.sub.7. The shoulder 6 transitions
to an inclined shoulder wall 34 which extends upwards and inwards,
and transitions to the standard neck inclined shoulder wall radius
R.sub.7. On an opposing side, the contoured neck has an inclined
shoulder wall with shoulder radius R.sub.1 and extending inwardly
and upwardly at contoured neck angle A.sub.1 which is distinct from
the first neck angle A3. The inclined shoulder wall extends
upwardly to contoured neck inclined shoulder wall radius R.sub.6.
The shoulder 6 transitions to an inclined shoulder wall 34 which
extends upwards and inwards, and transitions to the contoured neck
inclined shoulder wall radius R.sub.6.
