Description
FIELD OF THE INVENTION
[0001] The present application is directed to plastic bottles,
typically blow molded from PET material. In particular, the present
application is directed to such plastic bottles that include
gripping sections for round bottles of relatively large capacity,
e.g., 60 oz, 64 oz, 96 oz, 128 oz., etc.
BACKGROUND OF THE INVENTION
[0002] Many 96 oz. bottles are commercially available and prevalent
in consumer settings, such as grocery stores. See, e.g., U.S. Pat.
Nos. 6,273,282, 6,796,450, 6,257,433, 6,044,997 and 5,762,221. In
addition, so-called pinch grip containers are prevalent in the
field, especially in regard to 64 ounce bottles, see, e.g., U.S.
Pat. No. 5,165,557. However, there is an ever growing need to
improve bottles in terms of gripability, pourability, labeling,
reducing weight, decreased weight/material and/or increased
strength, etc.
[0003] Thus, a need has developed in the bottling art to provide
address one or more of these challenges.
BRIEF SUMMARY OF THE INVENTION
[0004] One aspect of the present invention relates to an improved
bottle design having a gripping section located above the bottle
label panel to enable labeling with a wrap around label using a
wrap around labeling machine.
[0005] Another aspect is to allow for material reduction, while
maintaining the bottle's strength and load capacity, as well as the
bottle's ability to accommodate for or otherwise resist vacuum
deformation.
[0006] Another aspect is to provide improved gripping and/or
pourability, e.g., by providing one or more raised beads in the
grip area of each gripping portion, and/or positioning and/or
dimensioning the gripping section relative to the remainder of the
bottle.
[0007] Another aspect is to provide an improved and/or coordinated
logo scheme, by providing relatively large logo areas on the upper
and lower portions of the bottle that are aligned and/or
coordinated with one another.
[0008] Another aspect is to provide for vacuum deformation flex
panels in the base, upper and/or lower portions of the bottle to
accommodate for any forces introduced during the pasteurization
process during a filling operation.
[0009] Another aspect is directed to a bottle having a reinforced
upper portion of the dome portion thereof, e.g., on a generally
round bottle.
[0010] The bottle described herein may be a hot-fillable or
cold-fillable plastic bottle. In one form, the bottle is made from
blow-molded plastic (e.g., PET or another suitable plastic).
[0011] According to one aspect of the invention, there is provided
a plastic bottle comprising a main body defining an upper portion
and a lower portion, the lower portion including a plurality of
vacuum flex panels, said lower portion including upper and lower
label bumpers to receive a wrap around label; and a
circumferential, recessed waist portion defining a transition
between the upper and lower portions of the main body, wherein the
upper portion includes a dome with a gripping section having a pair
of opposed grip portions positioned above the waist and recessed
into the upper portion.
[0012] One or more reinforcing or strengthening members, e.g.,
ribs, may be provided about or within the grip portions. For
example, one or more laterally extending ribs (e.g., 1-4 or more)
may be provided between the grip portions on the rear side of the
bottle. An arch body and/or ribs may be provided about the
perimeter or in the vicinity of the grip portion. The terms
"vertical" and "lateral" or horizontal are taken when the bottle is
resting upright on its base.
[0013] These and other aspects will be described in or apparent
from the following description of preferred embodiments.

DETAILED DESCRIPTION OF EXAMPLES
[0023] The following description is provided in relation to several
examples that may share common characteristics and/or features. It
is to be understood that one or more features of any one example
may be combinable with one or more features of the other examples.
In addition, any single feature or combination of features in any
of the examples may constitute an additional aspect of the
invention.
[0024] FIGS. 1-9 show examples of bottles made according to the
present invention. In the figures, reference number 10 designates a
plastic bottle or container, e.g. a polyethylene terephthalate
(PET), hot-fillable or cold-fillable beverage bottle. Typically, a
hot fillable bottle will include one or more (e.g., 4-6) vacuum
flex panels for deformation portions 55, while it is not necessary
for cold fill bottles to include such vacuum panels. However, a hot
fillable bottle can be used for cold fill applications. The bottle
may have a filling capacity of 64 oz., 60 oz., 96 oz., or smaller
than 60 oz. or larger than 96 oz., e.g., 128 oz., etc. Also, while
described in conjunction with round bottles, the features described
herein may also have application to other types of bottles, e.g.,
rectangular bottles, etc.
[0025] The bottle 10 includes a finish or neck 30 and a main body
40 that extends away from the neck 30. The neck 30 may be
crystallized to have a substantially opaque or white appearance, as
is well known in the art. However, it is not necessary to provide a
crystallized neck. The body portion 40 includes an upper portion 45
and a lower portion 50, which in the exemplary embodiment has the
vacuum flex panels or deformation portions 55, which may be in the
form of panel sections recessed into the lower portion, e.g., 1-5
mm or more. The vacuum deformation portions 55 accommodate internal
forces tending to collapse the bottle inwardly due to filling the
container 10 with a liquid at an elevated temperature, e.g., a
pasteurization temperature. After the container 10 is hot-filled
and capped, cooling of the liquid tends to collapse the vacuum
deformation portions 55. Each vacuum deformation portion 55 may
include at least one, e.g., 2-3, stiffening structures 56, e.g.,
truncated pyramids, to add rigidity, e.g., to prevent more than a
certain amount of deformation of the vacuum deformation portions
55. Upper portion 45 is shorter than the lower portion 50 in the
illustrated embodiment, although they could have the same height or
the lower portion 50 could be shorter than the upper portion 45. A
base or heel portion 25 is provided below the lower portion 50.
[0026] The bottle 10 is manufactured, for example, using a
blow-molding process which is well known. During blow-molding, a
preform (not shown) is expanded and assumes the shape of an
interior molding surface, i.e., a mold (not shown), to form a
substantially transparent, biaxially-oriented bottle. The neck 30
of the preform is not expanded and remains as the neck 30 of the
bottle 10. The neck 30 includes threads and an open mouth 35 for
receiving a screw-on cap (not shown). The lower portion of the
preform is expanded to form the body portion 40 of the bottle 10,
including the upper portion 45 and the lower portion 50.
[0027] While this example relates to hot-fill applications, it is
also contemplated that the bottle 10 can be used in cold-fill
applications. For example, the bottle can be made using an aseptic
cold-fill line.
[0028] Further, the lower portion 50 of the bottle 10 is adapted to
receive a label 61 (FIG. 4) which is wrapped, e.g., shrink-wrapped,
around the lower portion 50 and the vacuum deformation portions 55.
For example, the label 61 (only a portion is shown) wraps about the
entire perimeter of the bottle 10. The upper limit of label 61 is
positioned below an upper transition shoulder 54 between the top
and bottom portions 45, 50 of the body portion 40. A lower
transition shoulder 54.1 defines a lowermost boundary of the label
61. The label 61 could include one or more separate parts to be
individually applied to the label area.
[0029] A front side 45F (FIG. 4) of the upper portion includes a
logo portion 53 positioned opposite to a rear side 45R. The lower
portion 50 includes the wrap around label 61 having a logo 61.1
that aligns or is coordinated (e.g., size wise) with the logo
portion 53 provided on the upper portion 45 of the main body 10.
The logo portion 53 may possess a degree of vacuum deformation
capacity. Logo portion 53 may be embossed or debossed into the
upper portion 45. In addition, or in the alternative, logo portion
53 may also take the form of an adhesive label.
[0030] Bottle 10 includes a shoulder or dome portion 60 and a
gripping section 64 provided below shoulder 60. As shown in FIG. 8,
gripping section 64 includes a pair of grip portions 65 and a rear
wall 65.1 that connects the grip portions 65. Each grip portion 65
is inwardly recessed into the body portion 40. For example, the
grip portions 65 on opposite sides of the bottle 10 are spaced a
distance that is less than the width of the upper portion of the
bottle. Preferably, each grip portion 65 in particular a grip area
65.2 thereof, is recessed to a depth that progressively increases
when moving from the rear side 65R to the front side 65F of the
grip area 65.2. For example, the depth d12 at or near the rear side
65R is about 2-10 mm, e.g., about 3-5, and the depth d11 at or near
the front side 65F of the grip area 65.2 is about 5-25 mm, e.g.,
about 15-20 mm, as shown in FIG. 8. In embodiments, the depth may
be only a few millimeters, e.g., 1-5 mm, of a generally constant
depth.
[0031] Main body 40 includes a recessed or pinched waist portion 57
that divides the upper and lower portions 45, 50. As seen in FIG.
9, in cross section, the waist portion 57 has a generally round
shape with generally flat portions 57.1 positioned just below or
aligned with the grip portions 65. This flattened section may
influence the shape of the lower part of the grip portions as seen
in the top view of FIG. 5.
[0032] Although not shown, the border of each grip portion 65 may
include a ledge that improves gripability. Such a ledge if provided
would substantially surrounds the entire grip portion 65, although
it is possible that less than the entire perimeter of the grip
portion 65 includes the ledge. Further, although the grip portion
65 is shown as generally square or slightly trapezoidal with
rounded corners, it can take the form of other shapes such as
circles, diamonds, rectangles or other geometric shapes.
[0033] As shown in FIG. 8, in cross section, each gripping section
64 has three sides defining a generally U-shape, made up from the
generally parallel grip areas 65.2 and the wall 65.1 connecting the
grip areas 65.2. The upper ends of the generally U-shape grip
section 64 are flared outwards to connect to the curved or
cylindrical front surface 45F of the upper portion 45.
[0034] Each grip area 65.2 that extends from an imaginary plane P,
running parallel to and adjacent a longitudinal axis A of the main
body 10, to the rear wall 65.1 of the upper portion. As such, the
grip portions 65 are oriented asymmetrically on the upper portion.
A front wall 65.3 of the grip portion 65 transitions or flares into
the front side 45F of the upper portion 45 which is generally
cylindrical and corresponds to a maximum diameter of the upper
portion 45 at that point. The grip portions 65 include upper and
lower side walls 65U, 65L (FIG. 7) that, together with front wall
65.3, transition the grip area 65.2 to surrounding portions of the
upper portion 45 that are not recessed.
[0035] Each grip area 65.2 has at least one raised bead 90 (e.g.,
1-5 mm) extending generally vertically. The at least one bead 90
may include at least three beads having the same or different
heights. In the example shown in FIG. 7, the middle bead has a
length which is longer than the adjacent beads. At least one of the
beads is positioned along a transition between the grip area 65.2
and the front wall 65.3 of the grip portion 65.
[0036] Each bead 90 may be angled relative to a longitudinal axis
of the main body. The upper part of each bead has an upper portion
angled at an angle a towards a front side of the upper portion. The
angle a is about 1-15 degrees, e.g., about 3-5 degrees or about
5-10 degrees.
[0037] The rear wall 65.1 is dimensioned to engage a user's palm,
with the user's fingers and thumb engage the opposed grip portions
65 or grip or areas 65.2. The rear wall 65.1 includes at least one
lateral rib 75 extending between the opposed grip portions 65, for
strength and grippability. The at least one lateral rib 75 may
comprise at least 2-4 or more lateral ribs that are parallel to one
another and the waist portion 57. The lateral rib 75 is recessed
into the rear portion (e.g., 1-5 mm), but it may protrude as
well.
[0038] Bottle 10 may include an arch body 70 for each grip portion
65 positioned at least along a portion of a rear wall 65.1 of the
grip portion 65. The arch body 70 may be recessed or protruding,
e.g., 1-5 mm, and is positioned between the rear side 65R of each
grip area 65.2 and the at least one lateral rib 75 that extends
between the grip portions 65. Each arch body 70 may also extend
adjacent a top border 65T of the grip portion 65, as seen in FIG.
7.
[0039] Bottle 10 may include at least one rib 80 (1-5 ribs)
positioned on a front side 45F of the upper portion 45, adjacent
each said grip portion 65. The at least one rib 80 extends between
the neck 30 to the waist portion 57. One of the ribs 80 may extend
past arch body 70, as seen in FIG. 7. The combination of ribs 75
and 80 along with arch body 70 (and even the logo portion 53)
cooperates to provide improved strength (e.g., top loading
strength), and/or resistance to squeezing and vacuum deformation
forces, while at the same time requiring less material usage.
[0040] The bottle may also include a vacuum array, e.g., including
one or more vacuum deformation portions positioned on the top
portion 45 of the main body. For example, grip portion 65 and/or
logo portion 53 may possess vacuum deformation capacity.
[0041] In this particular embodiment, bottle 10 has a volume
capacity of about 96 oz. Exemplary dimensions d1-d12 of the bottle
are shown in the various drawings, for example:
[0042] d1 is about 290-310 mm or about 300 mm;
[0043] d2 is about 120-130 mm or about 125 mm;
[0044] d3 is about 40-50 mm or about 45 mm;
[0045] d4 is about 70-80 mm or about 75 mm;
[0046] d5 is about 70-80 mm or about 75 mm;
[0047] d6 is about 15-25 mm or about 20 mm;
[0048] d7 is about 125-135 mm or about 120 mm;
[0049] d8 is about 140-150 mm or about 145 mm;
[0050] d9 is about 70-90 mm or about 75-80 mm;
[0051] d10 is about 40-50 mm or about 45 mm;
[0052] d11 is about 5-25 mm or about 15-20 mm;
[0053] d12 is about 2-10 mm or about 3-5 mm;
[0054] d13 is about 130-135 mm or about 135 mm; and
[0055] d14 is about 60-70 mm or about 65 mm.
Those of ordinary skill in the art would appreciate that aspects of
the present invention are applicable to other containers, such as
round or polygon shaped, e.g., square, pentagon, hexagon, septagon,
octagon, etc., bottles, which may have different dimensions and
volume capacities (+/-10-20% or more).
[0056] The grip portion 65 is adapted to be grasped by the fingers
and thumb of a person of average size, for example, an average
woman having a size 7 hand. For example, as shown in FIG. 3, the
distance d9 between the grip portions 65 is about 70-90 mm, e.g.,
about 75-80 mm, although the distance can range lower than 70 and
higher than 90. However, the grip portion 65 is not limited for use
by a person having average size hands.
[0057] As seen in the cross-sectional view of FIG. 8, at least a
portion the grip area 65.2 of the grip portion 65 is provided near
or at the longitudinal axis A of the main body of the bottle to
facilitate holding of and pouring liquid contents from the
container 10. However, as seen in FIGS. 3, 4 and 7, the grip
portions 65 are above the waist portion 57 and therefore above the
center of gravity.
[0058] While the invention has been described in connection with
what are presently considered to be the most practical and
preferred embodiments, it is to be understood that the invention is
not to be limited to the disclosed embodiments, but on the
contrary, is intended to cover various modifications and equivalent
arrangements included within the spirit and scope of the invention.
For example, while an exemplary hot-fellable container has been
described, the disclosure is not limited to such and
non-hot-fellable containers are also possible in which event vacuum
panels would not be required. In addition, while PET containers
made using a blow-molding process have been described, other
materials and manufacturing processes are also possible. For
example, the container can be made using extrusion molding or other
stretch molding techniques, and the container could be made from
materials such as, for example, polypropylene, high density
polypropylene, polyolefin, styrene and other similar plastic
materials.
