Abstract
An integrally molded carrier for carrying three containers by their necks includes a substantially planar web having three nodes and defining three annular support rings. Annular neck-engaging flanges integral with the web are arranged around the inside of the support rings for releasably engaging the necks of containers. The centers of the support rings are situated in the web such that they correspond to the three corners of a triangle.
Description
BACKGROUND OF THE INVENTION
Multiple bottle carriers for holding and carrying bottles or jugs by their necks are well known. A common type of commercially available carrier is fabricated from thin gauge sheets of plastic. The thin planar sheet is die-cut to provide holes for engaging the necks of the containers and holes for grasping the carrier, and is thermo-formed into a three- dimensional shape to provide structural integrity to the carrier. There are several problems with this carrier. First, the thermo-formed plastic sheet shrouds the container, obscuring visibility of the product and product labels. Second, the thin gauge of the plastic material makes the carrier uncomfortable to carry.
An integrally molded carrier for carrying multiple containers by their necks is disclosed in commonly owned U.S. Pat. No. 6,129,397. The carrier disclosed therein is designed to carry six large bottles, typically one-gallon plastic jugs containing a liquid such as milk, fruit juice or water. While such products are sold in bulk in packs of six, it is advantageous from a pricing standpoint for retailers to sell
64
ounce or half-gallon bottles three to a package.
Carrying handles for three bottles, however, are awkward and difficult to use. An example of such a carrier is shown in U.S. Pat. No. 4,093,295, which discloses an in-line design bottle carrier capable of carrying three bottles by their necks by means of three uniformly spaced split collars mounted within a frame interconnected by a single row of longitudinally extending rigid bars. The carrier features two loops on the outside of the necks of the bottles which must be pulled up and grasped by the user. These handles tend to stick up above the necks of the bottles, making the bottle/carrier combination difficult to ship. The 295 carrier is also difficult to apply to groups of three bottles with automated equipment. In addition the in-line design of the 295 carrier makes the lifting of three half-gallon bottles awkward.
BRIEF SUMMARY OF THE INVENTION
The present invention provides an integrally molded carrier for carrying multiple containers by their necks and includes a substantially planar web having three nodes defining three annular supports. A flexible annular neck-engaging flange integral with the web is arranged within each annular support for releasably engaging the necks of containers. The centers of the annular supports correspond to the three corners of a triangle, preferably a right triangle.
In one embodiment, the web has three branches including a medial branch and a pair of lateral branches extending from each side of the medial branch so as to form a substantially T-shaped web structure. The web may include scalloped edges adjacent the medial branch for providing a comfortable gripping handle for the carrier.
In a second embodiment, the web is substantially triangular in shape with the sides of the triangle being inwardly radiused, and includes an arcuate opening which, together with the web, forms a handle.
The geometry of both web designs provides a balanced bottle carrier that enables three bottles to be lifted by hand and easily carried. With the web's triangle geometry, the three bottles are balanced relative to the gripping handle so that their weight is distributed evenly.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Referring to the drawings, wherein like numerals generally refer to the same elements, there is shown in
FIGS. 1-3
a bottle carrier
10
for carrying three bottles that includes a substantially planar web
12
having three nodes preferably formed from a flexible material such as plastic. Web
12
has three branches: a shorter medial branch
14
and a pair of laterally extending longer branches
16
and
18
which join medial branch
14
so as to form a T-shaped structure. Branches
16
and
18
are preferably canted slightly at an angle from medial branch
14
. Web
12
includes an inner portion
20
which is continuous and flat. Support ridges
22
,
24
and
26
are formed on the peripheral edges of the three branches to provide structural rigidity. Support ridges
22
and
24
are radiused so as to create scalloped portions
22
a
and
24
a
along medial web branch
14
.
Each of the branches
14
,
16
and
18
terminate in nodes having identical flexible annular neck-engaging structures
28
,
30
and
32
that are integral with web
12
. Because the neck-engaging structures are identical, for simplicity, details of their structure will be limited to a single such structure, i.e., neck-engaging structure
30
.
Neck-engaging structure
30
is provided with a circumferential ridge
30
a
to provide structural rigidity and with annular flange
30
b
. Annular flange
30
b
is flexible for ease in placing over and removing the same from a bottle neck, and is joined to circumferential ridge
30
a
by radial ribs
30
c
. Annular flange
30
b
is frusto-conically shaped so as to flex in an upward direction when the bottle carrier is pushed in a downward direction over the necks of the bottles and then to bear at an upward angle against the weight of the bottles when the carrier is lifted. Annular flange
30
b
also has inner edge portions
30
d
that are substantially flat. The flat portions of annular flanges
30
b
make it easier to engage a bottle neck with the annular flange and also make it easier to disengage the carrier when pry tab
30
h
is lifted. Annular flange
30
b
is also provided with sets of reinforcing ribs
30
e
that extend in a generally radial direction and sets of relief slots
30
f
also extend radially, permitting the annular flanges to flex when the necks of bottles are either engaged or disengaged.
Annular neck-engaging structures
28
,
30
and
32
are preferably arranged so that their centers, when joined by imaginary lines, form the corners of a triangle, preferably substantially a right triangle. This geometry provides balance for the three bottles held by the carrier. When balanced against each other in this fashion, even heavy half-gallon bottles are easy to carry when using the web
12
as a handle.
Pry tab
30
h
is useful for disengaging the annular neck-engaging structure from the necks of the bottles. Adjacent pry tab
30
h
on the inside of support ridge
30
a
is an open space
30
g
. In other words, annular flanges
30
b
do not complete a full circle inside the support ribs but instead a space is left to further facilitate their removal from the necks of the bottles held by the carrier. The flanges still have the structural rigidity necessary to support the weight of the bottles because the flanges are shaped frusto-conically extending in an upward direction and are structurally reinforced by the radial support ridges
30
e.
Referring to
FIG. 4
, there is shown a second embodiment of the invention comprising a bottle carrier
10
′ having three nodes that includes a web
12
′, the central portion of which is generally triangular in shape with inwardly radiused sides
40
,
42
and
44
. Each of the radiused sides are provided with support ridges
22
,
24
and
26
. An arcuate opening
46
in web
12
′ is provided adjacent one of the three nodes to provide, in cooperation with the web
12
′, a handle for the carrier
10
′. Arcuate opening
46
is also provided with a support ridge
48
around its periphery.
The three nodes of carrier
10
′ are each provided with identical annular neck-engaging structures
28
′,
30
′and
32
′ having similar but not identical construction to the neck-engaging structures
28
,
30
and
32
of carrier
10
. Each neck-engaging structure is provided with a circumferential ridge
30
a
, an annular flange
30
b
and slots
30
f
; however, the reinforcing ribs
30
e
are provided only on the inner portion of annular flange
30
b
, there is no open space
30
g
nor are there any radial ribs
30
c.
Although the carrier web is preferably arranged in the shape of a right triangle, it does not have to be shaped in a right triangle to function properly. Any triangular shape will provide the benefits of the invention as long as the bottles held by the laterally disposed flanges are substantially evenly balanced relative to the medial branch of the web. Thus triangular shapes other than right triangles may be employed. Other types of neck-engaging flanges may work as well. For example, flat flanges, not conically shaped, may have enough structural rigidity to grasp and hold the necks of bottles. Nor is it necessary for the embodiment shown in
FIGS. 1-3
that the flanges be set apart from the annular supporting ribs by radial ribs; the web and the flanges may be integral as shown for the embodiment in
FIG. 4
if the web material is strong enough. A preferred material of construction is flexible polyolefin, more preferably high density polyethylene and most preferably recyclable high density polyetheylene.
The terms and expressions which have been employed in the foregoing specification are used therein as terms of description and not of limitation, and there is no intention in the use of such terms and expressions of excluding equivalents of the features shown and described or portions thereof, it being recognized that the scope of the invention is defined and limited only by the claims which follow.
