Back~round of the Invention


Various types of carriers have been revealed in the patent arts and
have been used commercially for assembling a predetermined number of
containers, often six in number, for carrying of the containers. Typically,
six cans may be carried together, and in a preferred form of package there
5 is a sheet of plastic having six apertures therein respectively slightly less
in diameter than the cans, so that the plastic material is stretched about
the respective cans in generally inverted conical shape, thus secrely under-
lying the can beads to prevent undesired withdrawal of the cans. As is
known, a lateral movement of a can stretches the respective encircling
lo band so that the can can be tipped from carrying position. Such carriers
are shown, for example, in U.S. Patent Nos. 2,~74,~35 and 3,g74,502.
Larger numbers of cans have been handled by similar carriers, see for
example, U.S. Patent No. 4~OI8J331 shows a carrier of the type in question
for 12 cans.


Under some circumstances a package of 12 cans may be somewhat
unstable or difficult to carry, and in U.S. Patent No. 4,269,30~ there is
shown and described a plastic encircling band which circumscribes the 12
cans and holds them in close continuous relation. The band is provided
with a handle for carrying of the 12 pack.


20 Summary of the Present Inve~tion

The present invention seeks to provide an encircling band carrier
for a plurality of cylindrical containers which may be otherwise
secured together, which carrier ensures stability of the resulting
package of containers.
More specifically, this invention seeks to provide an
integral band plastic carrier for a double six pack of cans, or a double

1 four pack of bottles in which each of the subpackages is fully
encircled,
In one broad aspect, the invention pertains to a package
unit comprising a plurality of cylindrical containers arranged in
rows and columns, and a package unit carrier comprising a first
resilient strip circumscribing all of the containers in surface
contact therewith and an intermediate resilient strip integral with
the first strip and extending between spaced portions thereof. The
intermediate strip extends between predetermined adjacent containers
in surface engagement therewith, each of the containers being
engaged by at least one of the strips to provide a stable package.
The invention also pertains to a package unit carrier comprising
a first integral resilient plastic strip formed as a continuous
loop, handle means integral therewith, and an intermediate strip
extending across the loop and having opposite ends integral with
the first strip.
More particularly, the present invention provides for a plastic
package unit which completely encircles a group of cylindrical
containers, such as a double six pack of cans, or a double four pack
of bottles. A subsidiary dividing band is provided which lies
between the subpacks, such as the two six packs of cans, whereby
each subpack is retained in stable condition independently, while
the total package is also retained in stable condition. The band
or package unit is initially provided stamped from a sheet of plastic
material in collapsed condition, with the outer portion thereof
forming the overall encircling band, and with an inner portion providing
a collapsed separating strip. Successive package units are integrally
joined together in an elongated strip, and are separated preferably
after assembly with the cans or other containers.

Detailed Description of the Illustrated Embodiment


Referring now in ~reater particularity to the drawings, and first to
FIGS. 19 2 and 5, there will be seen a plurality of cylindrical containers,
specifically cans 20 totalling 12 in the illustrative example. As seen in
FIG. 1, the cans are displayed with their axes in horizontal disposition in
20 four columns oI three cans each. The two left columns are secured to-
gether by a pJastic can carrier 22, preferably made of polyethylene, the
carrier shown in the aforesaid U.S. Patent No. 2,874,S35 being illustrative.
A similar carrier 24 secures the two right columns of cans together. There
are thus two six packs of cans which could be carried separately, ~enerally



-- 4 --

,, :

11757~37 Case 3906 20

with the can axes in vertical position. Although such carriers are set
forth in detail in prior art patents, such for exampied the aforesaid U.S.
Patent No. 2,874,835, it is noted by way of summary at this point that
each such carrier comprises an apertured sheet having six apertures therein,
5 each slightly less in diameter than a can, thus effectively providing six
separate bands which aggressively grip the cans beneath the beads thereof.
Inherent resilient or stretchable characteristics of the plastic material allow
a can to be pulled a slight distance sideways to stretch the respective
band, whereby the can can be tipped away from the respective carrier.


In many instances, it is convenient to carry 12 cans as a unit, rather
than six. Thus, in accordance with the present invention, a 12 pack band
or package unit carrier 26 is provided.


The shape of the 12 pack band or package unit carrier 26 in blank
form before assembly with the cans is shown in FIG. 2 and comprises a
continuous outer strip 28 having arcuate end portions extending over
greater than a semicircle and ~oin to elongated reversely curved portions
32 integrally interconnecting the arcuate portions. The strip 28 is of uni-
form width and at its vertical centerline is provided with integral attach-
ment polnts 34 for narrower V-shaped strips 36-1 and 36-2 arranged hori-
zontally in mirror-image relation. The apices of the strips 36-1 and 36-2
are rounded as indicated at 38-1 and 38-2, while the roots 40-1 and 40-2,
and 42-1 and 42-2 are also rounded to avoid stress areas that might tezr.


The pack band or package unit carrier 26 is completed by a handle
44 integral with the strip 28. The handle is symmetrical about the vertical
midline of the carrier and is integral with the reversely curved portion 32.

The handle 44 is provided with two apertures 46 and 48 in mirror-image
relation. Since the apertures are of the same shape, only the left one is
described, and includes an elongated, rather narrow opening 50 running the

117578~
Case 3906 20




length of the aperture 46, and having a generally circular enlargement 52
at the upper edge of the narrow portion 50 and at the left end thereof.
This leaves a flap 54 which can be folded up. An integral tab 56 on the
vertical midline of the carrier connects the central portion of the handle
5 with the strip 28. The first two fingers of a hand may be inserted through
one of the apertures 46 and 48, while the last two fingers are inserted
through the other of these apertures. The flap 54 in each instance rolls
up to present a smooth, surface engagement with the fingers, rather than
a sharp edge. This promotes comfort of the person doing the carrying,
10 and also inhibits tearing of the plastic material.


A succession of 12 pack bands or package unit carriers 26 is pro-
vided in the form of a continuous web, and ragged lines 58 at either end
in FIG. 2 indicate where successive carriers are supplied integrally joined
toE~ether. The connection preferably is severed during or immediately prior
15 to assembly with a pair of six packs, hereinafter respectively referred to
by numerals 60 and 62.


As shown in Fl(~. 1, the strip 28 is extended around the two six
packs 60 and 62 with the respective intermediate strips 36-1 and 36-2
pulling together as a single, straight strip 36. As will be appreciated, the
20 length of the strip 28 and of the strip 36 are such that they will fit in
the positions just shown and described, each under some tension. Accord-
ingly, all of the cans are held in tight assemblage whereby the double six
packs can conveniently be carried by the handle 44 without danger of any

of the cans coming loose either from the package unit carrier 26, or from
24 the respective six carriers 22 and 24.


A modification of the invention as just described is shown in FIGS.
3 and 5. In this embodiment oi the invention, the parts are essentially
identical with those previously described and are correspondingly numbered.


~:175787 Case 3906 20


The distinction is that the handle 44 has been moved to the left end of
the strip 28. The handle is provided with two apertures 60 and 62, again
in mirror-image relation. Due to the shape of the arcuate end portion 30
the inner edge of each aperture is a continuous curve at 64, while the
5 outer edge 66 thereof is straight. This results in a relatively large di-
mension at the maximum upper and lower vertical limits, but with a very
restricted opening adjacent the hori~ontal centerline. Accordingly, the
integral center tab 68 may be scored or otherwise weakened as indicated
at 70 so that when it is desired to pick up a double six pack the tab 68
10 may be readily torn to allow all four fingers to be inserted comfortably
in the apertures 64 and 66.


An embodiment of the invention adapted for carrying eight bottles
is shown in FIGS. 4 and 6. The parts are generally similar or identical to
those previously shown and described, and therefore similar parts are iden-

15 tified by similar numerals with the addition of the suffix a. Points oIdistinction are that the strip 28a is narrower than the strip 28, while the
intermediate strip 36a is considerably shorter, having to span only two
bottles 20a, instead of three cans. Accordingly, as seen in FIG. 4, the
strips 36a-1 and 36a-2 do not extend as far to the right and to the left
20 as is the case with the corresponding intermediate strip portions in FIG.
2.


The bottles, as shown in FIG. 5, are arranged in two groups of four,
and each group preferably is held together by a plastic carrier (not shown)
receiving the necks of the bottles, and generally is similar to the plastic
25 six pack carriers of FIG. 1, but with smaller holes having greater spacing.
The two four pack units are arranged with one vertically above the other,

~ith the strip 28a encircling the assemblage, and the intermediate strip
36a extending between the two four bottle units whereby the eight bottles
are securely held together for transpor t, hanging from the handle 44a.


~l~S787
Case 3906 20




A further embodiment of the invention is shown in FIG. 7. This
embodiment is generally similar to those previously disclosed, and similar
parts are identified by similar numerals with the addition of the suffix b
to avoid prolixity of discussion. The handle 44b is shown at the left end,
5 as in FIGS. 3 and 4, but it could equally well be along the top as indi-
cated in broken Jines, and as previously shown in FIG. 2. The essential
distinction of the present embodiment over prior embodiments is that the
strips 36b-1 and 36b-2 ultimately forming the center strip 36 are of
generally horseshoe-shaped configuration rather than V-shaped. Thus, there
are side legs 72-1 and 74-1 in close proximity and near parallelism with
the adjacent reverse curved sections 32b, connected by a large arcuate
section 76. Similarly, there are straight legs 72-2 and 74-2 interconnected
by a large arcuate section 78. With the proximity to the reversely curved
strip portions 32b, there are integral connections 80-1, 80-2, 82-1 and 82-2
15 between the respective legs and the respective reverse curvature portions
of the strip 30b. These interconnections are rather narrow, and may be
weakened by means such as score lines for ready severability during assembly
of the carrier with the containers. Prior to such severing, the connections
hold the center strip portions 36b-1 and 36b-2 in the same plan as the
20 balance of the carrier 36b without requiring any separate handling thereof.


The carrier of ~IG. 7 is especially adapted for retaining eight bottles,
but it could be used for a double six pack if dimensions were changed
accordingly. Additional embodiments especially adap~ed to carry eight
bottles are shown in FIGS. ~, 9 and 10. With reference at this time to
25 FIG. 8, parts there are similar to those previously described, and similar

numerals are utilized with the addition of the suffix _ to identify like
parts. Distinctions reside in the fact that the arcuate end portions 30c
are of considerably greater arcuate extent than in previous embodiments,
and instead of having the arcuate portions at opposite ends of the carrier


~17S787 Case 3906 20


merge into a single rather long portion of reverse curvature, there are
rather short portions of reverse curvature of considerably smaller radius
joining the end portions to straight side portions 86. This resu~ts in the
top and bottom portions of the strip 86 being considerably closer together
5 than in previous embodiments of the invention. The strip portions ulti-
mately to form the intermediate or divider strip 36c are again of generally
horseshoe shape, but considerably narrower (less height from top to bottom
in FIG. 8). The adjacent end of the leg pairs 72c-1, 74c-1 and 72c-2,
74c-2 are integrally interconnected by roots 88-1 and 88-2. The roots
have margins of relatively small radius to avoid stress concentrations, and
a central aperture 90 is defined by the roots and associated structure.


Attention next should be directed to the embodiment of FIG. 9 in
which like numerals are again utilized to identify similar parts, this time
with the addition of the suffix d. Production of the embodiment illustrated

15 in FIG. 9 results in a minimum of scrap, since the width of the blank is
minimized. The arcuate end portions 30d extend over only 180, and are
of shorter radius than in previous embodiments. There are no reversely
curved or inverse sections such as 32 or 84, but rather the straight side
portions 86d are tangent to the arcuate end portions 30d. It will be

20 apparent in connection with both embodiments of FIGS. 8 and 9 that the
roots 88-1 and 88-2 could be scored or otherwsie weakened to facilitate
severence thereof upon assembly of the carrier with a plurality of bottles.


A further embodiment of the invention as disclosed herein is shown
in FIG. 10. Similar parts again are identified by like numbers with the


25 addition of the suffix e. This form of the invention is similar to that in
FIG. 9 in that there are straight upper and lower portions 86e of the
outer strip 28e. In this instance the curved end portions 30e are of
greater diameter and the straight portions 86e thus are spaced farther


~17S787 Case 3906 20

apart. The portions 36e-1 and 36e-2 destined to form the intermediate
strip are semi-circular in the present form of the invention, and are
joined along the horizontal median line of the carrier 36d by a crossbar
88 integrally formed therewith and having fillets formed by small radii.
As in prior forms of the invention, the two strip portions 36e-1 and 36e-2
are being pulled together, not apart, and there is no particular danger of
a split between these strip portions. Nevertheless, it is preferred that
the strip portions be joined to one another by a small radius at either
end to avoid any provlems of splitting or tearing.

A still further modification of the invention is shown in FIG. 11,
again with similar elements identified by like numerals with the addition
of the suffix f. The distinction being that intermediate strip 36f is a
single strip rather than a double strip. It is, therefore, noted that the
intermediate strip 36f initially is secured with a vertical upper portion
34f connected at 42f to the straight portion 31f of the strip 2~f. The
strip continues down to an upwardly curved, nearly semi-circular portion
64f, which then reversely curves into a horizontal section 66f ]oined to
the straight upper portion 31i along a fracture line 68f which may be
perforated, creased, or otherwlse weakened for severability at that location
during assembly. The horizontal portion 66f continues into a substantially
semi-circular portion 70f which leads to a slightly inclined upward portion
72f connected to the reverseiy curved strip portion 32f along a severability
line 74f which may be perforated, creased, or otherwise weakened for sub-
sequent severance durlng assembly of the carrier with a double six pack of
cans. The intermediate strip portion 72f continues into a generallv semi-
circular portion 76f which continues vertically down at 78f in alignment
with the upper portion 34f, being integrally connected to the reversely
curved strip portion 32f at the roots 40f. The two semi-circular portions
64f and 76f abut and are in~egrally Joined to one another along a severable
area 80 which again may be perf orated, creased, or otherwise weakened.

- 10 -

~ ~ ~ f C~ ~ Case 39G6 20




The upper portion of the strip 36f defines an aperture 82f between
the intermediate and the horizontal strip portion 31f, while a like aper-
ture ~4f is defined between the lower portion of the intermediate strip
36f and the reversely curved strip portion 32f. The generally straight
5 portions 66f and 72f of the intermediate strip, plus the semi-circular por-
tion 70f, and adjacent portions of the smaller radius semi-circular portions
64f and 76f define another aperture ~6f.


In each embodiment of the inven~ion as shown and described herein,
there is provided a band-type carrier for a 12 pack of cans or an eight
pack of bottles which has a band encircling the outside of the package,
and which further has an intermediate band extending between containers
within the package, whereby every container is engaged by a portion of
the pack band or package unit carrier, thereby to provide enhanced stability
for the overall package. The carrier is inexpensive to produce, being made
15 from a thermoplastic resin such as polyethylene, and being stamped from a
continuous web of such material with the scrap being capable of reclama-
tion. In the instance of the embodiments of FIGS. 2 through 10, the inter-
mediate strip or band comprises initially a pair of narrow strips initially
displaced from one another, which strips are pulled into close contiguity
20 upon assembly with the containers, forming in effect a single strip. The
carrier forms surface engagement with the containers as the parts are
stressed into position. In the instance of the embodiment of FIG. 11, the
intermediate strip comprises but a single initially collapsed strip or band.


The specific examples of the invention as herein shown and described

25 are for illustrative purposes. Various changes in struction will no doubt
occur to those skilled in the art, and will be understood as forming a part
of the present invention insofar as they fall within the spirit and scope of
the appended claims.
