CROSS REFERENCES TO RELATED APPLICATIONS
This is a continuation-in-part of an earlier filed application Ser.
No. 15,408, filed Mar. 2, 1970 and abandoned concurrently with the
filing of this application.
BACKGROUND OF THE INVENTION
This invention relates to a multiple-article carrier in general and
more particularly, to a multiple-article carrier of the wrap-around
variety and having a novel end panel retention means which serves
as a secondary means of retaining the article in the package.
As is well known in the prior art, the use of one-way, disposable
containers such as bottles and cans has increased rapidly in recent
years. The increased use of these containers has led to an
increased demand for less expensive carriers which might be
discarded after a single use. As is also well known in the prior
art, this demand for less expensive carriers led to the development
of the wrap-around style carriers which require a reduced amount of
blank material, and hence, which can be produced at a reduced
cost.
For the most part, the prior art wrap-around carriers have proven
quite satisfactory; however, under certain circumstances it has
been possible for the articles in the end positions of the package
to slip therefrom. For this reason, several attempts have been made
to securely fix the end articles in position. For example, it is
known to utilize various cutouts, flaps and tabs, either singly or
in combination to improve the retention characteristic of the
wrap-around carrier.
One such attempt is shown in the patent to Wesselman, U.S. Pat. No.
2,276,129, issued on Mar. 10, 1942 wherein a pair of retention end
panels 16 are formed by cutting the panels out of the side panels 3
and 13 thereby considerably weakening the carrier. A similar type
end panel is formed in the patent to Gray, U.S. Pat. No. 2,527,478,
issued Oct. 24, 1950 with the panel being formed mostly from the
bottom panel 10, also structurally weakening the carrier. Carriers
of these types have the disadvantage of being expensive to form and
use and also are not readily adapted to handle both bottles and
cans.
Other retention means in the form of corner panels have been tried
as illustrated by the patent to Hickin, U.S. Pat. No. 3,429,496
issued Feb. 25, 1969 and the patent to Fielding U.S. Pat. No. RE.
24,667, issued July 14, 1959. These carriers have the disadvantage
of not having the secondary retention means formed at the central
portion of the article to be carried to give maximum protection
from bottle dropout if the primary retention means fails. For
example the Hickin retention panel 30 will serve to retain only the
upper portion of the bottle 11 if the bottom primary retention
means 25 fails thereby possibly allowing the bottle to drop out of
the carrier. In a similar manner the Fielding carrier may not be
able to prevent a bottle dropout in the event either the upper or
lower corners 18 fail, since this carrier contains no secondary
retention means for double protection.
A similar situation may be encountered in the Chidsey patent, U.S.
Pat. No. 2,687,247, issued Aug. 24, 1954 wherein no secondary
retention means is provided for bottle dropout. In addition, this
carrier failed to provide adequate primary retention means which
would allow the carrier to be completely turned over without having
a bottle or can drop from the carrier.
BRIEF DESCRIPTION OF THE INVENTION
In order to overcome the problems encountered in these prior art
devices, there has been provided, by the subject invention, a new
and improved wrap-around article carrier having a secondary
retention means in the form of adjustable end panels which may be
located near the central portion of the end bottles or cans. The
secondary retention means thus formed and located provides maximum
protection from bottle dropout in the event the primary retention
means fails for reasons known in the art. With the adjustable end
panel, the carrier is more readily adapted to handle the large
variety of bottles and cans on the market today.
Accordingly, it is an object of this invention to provide an
improved wrap-around style carrier having an improved secondary
retention end panel which serves as a secondary means of retaining
the articles in the carrier in the event the primary retention
means fails. Still another object of this invention is to provide a
wrap-around article carrier having a secondary retention end panel
which can be easily erected to a finished package and which
provides maximum protection against bottle dropout. Yet another
object of this invention is to provide a retention end panel which
may be conveniently used in wrap-around carriers for both bottles
and cans. These and other objects and advantages will be apparent
from the description hereinafter set forth and the accompanying
drawings.
In accordance with the present invention, the foregoing and other
objects, are accomplished with a carrier, of the wrap-around
variety which may be formed from a single sheet of blank material,
which blank is cut and scored to form said carrier. The carrier
will comprise top, side and bottom panels and secondary retention
end panels suitably secured to said side panels. The end panel or
strap will be conveniently positioned in the central portion of the
package ends and serves as a secondary means of retention in the
event of failure of the standard primary retention means.

PREFERRED EMBODIMENT OF THE INVENTION
The essence of the present invention resides in the secondary means
employed in combination with a conventional wrap-around carrier
having a standard primary retention means to prevent articles from
slipping or dropping out of such carriers through the open or
substantially open ends thereof whenever the primary retention
means fails. More particularly, the essence of the present
invention resides in the use of a secondary retention means in the
form of a retention end panels or straps which panels or straps are
(1) suitably secured to the side panels of such a carrier through a
gusset-like arrangement of panels, and (2) are separated from both
the top and bottom panels and are located in the central portion of
the bottle or can to provide maximum protection from bottle or can
dropout. As will become more apparent from the disclosure set forth
hereinafter, the separation of the secondary retention panel from
both the top and bottom panel of the carrier affords protection in
the central portion of the open end area with a minimum amount of
blank material and a maximum amount of protection. In turn, the
central positioning of the secondary retention panel permits its
use in combination with carriers designed for either bottles or
cans of all types and shapes since the protection afforded is
independent of the article's shape at either the top or bottom
thereof.
Although the secondary retention panel of the present invention, as
has been previously noted, is equally adaptable for use with
carriers designed for either bottles or cans, the invention will be
described herein, for convenience, by reference to a preferred
embodiment thereof; ie. by reference to a carrier specifically
designed for chimed cans. The modifications which would be
necessary to convert the can carrier, as illustrated, so as to
facilitate the packaging of bottles therein, will, of course, be
obvious to those of ordinary skill in the art.
Referring then to FIG. 1, there is shown a unitary sheet of blank
material which is cut and scored so as to define the bounds of the
various panels and other elements of a carrier within the scope of
the present invention. The blank may be prepared from paper,
paperboard, polymeric sheet material, etc. As can be seen in the
Figure, the blank comprises a top panel, 1, which is pivotally
connected to side panels, 2 and 2' along scored fold lines, 3--3
and 3'--3'. In the embodiment illustrated, the top panel, 1, is
separated from the side panels, 2 and 2', along cut lines, 4--4 and
4'--4'. As will be more readily apparent from the disclosure as set
forth hereinafter, the cut lines, 4--4 and 4'--4', define slits in
the upper portion of the side panels, 2 and 2', respectively, which
serve as a portion of the primary means of retaining the articles
in the carrier by holding the upper chimes of cans when such
containers are placed in the carrier.
Margins, 5 and 5', are pivotally attached to side panels, 2 and 2',
respectively, along scored fold lines, 6--6 and 6'--6' and
separated therefrom by cut lines 7--7 and 7'--7'. The cut lines,
7--7 and 7'--7', are fashioned so as to provide slots in the lower
portions of side panels, 2 and 2', respectively, for receiving the
outer portions of the bottom chimes of cans placed in said carrier.
The slots formed by the cut lines 7--7 and 7'--7' form the
remaining portion of the primary retention means for retaining the
articles in the carrier. The primary retention means just described
is well known in the art and forms no part of the subject invention
except as used in combination with the new secondary retention
means hereinafter described.
Flap, 8, is pivotally attached to margin, 5, along scored fold
lines, 9--9, and separated therefrom along irregular cut lines,
10--10, which cut lines define locking tabs, 11--11. Flap, 8, is
formed with cutouts, 12--12, which, in part, define locking bars,
13--13. A locking flap, 14, is cut from margin, 5', and pivoted
thereto along scored fold line, 15. The locking flap, 14, carries
locking tabs, 16--16, which are pivotally connected thereto along
scored fold lines, 17--17. Locking bars, 18--18, are formed, in
part, by the cut lines which define the terminal boundaries of the
locking tabs, 16--16, and, in part, by a continuation of this line
which cooperates with curved cut lines, 19, and 20, to define a
cutout, 21. Separating tabs, 22--22, are also cut from margin, 5',
and pivoted thereto along scored fold lines, 23--23. Tabs, 24--24,
are fashioned so as to provide a slit in the separating tabs,
22--22, to facilitate a portion of the can chimes when such
containers are packaged in the carrier.
The top panel, 1, is also cut so as to define separating tabs,
25--25, which are pivotally attached thereto along scored fold
lines, 26--26. Tabs, 27--27, are fashioned so as to provide slits
in the separating tabs, 25--25, which will facilitate a portion of
the upper chimes of cans which are packaged in the carrier. The top
panel is also provided with tabs, 28--28, which are pivotally
attached thereto along scored fold lines, 29--29. These tabs may be
rotated downwardly so as to provide means for lifting the carrier
when erected.
The novel secondary retention means in the form of retention end
panels, 30 and 30', are secured at their respective ends along
scored fold lines, 31 and 32 and 31' and 32', to side panels, 2 and
2'. As can be seen in the Figure, the secondary retention end
panel, 30, is secured to side wall panel, 2, through a combination
of triangular folding panels, 33 and 34, which are pivotally
attached to each other along scored fold lines, 35, and to the
secondary retention end panel along scored fold line, 36.
Similarly, the secondary retention end panel, 30', is secured to
side panel, 2, through a combination of triangular folding panels,
33' and 34', which are pivotally attached to each other along
scored fold line, 35', and to the secondary retention end wall
along scored fold line, 36'. The secondary retention end panel, 30,
is attached to side panel, 2', through triangular folding panels,
37 and 38, which are foldably attached to each other along scored
fold line, 39, and to secondary retention end panel, 30, along
scored fold line, 40. In the same manner, the secondary retention
end panel, 30', is secured to side panel, 2', with triangular
folding panels, 37' and 38', which are hinged along scored fold
line, 39', to each other and to the secondary retention end panel,
30', along scored fold line, 40'.
In order to better understand the present invention, reference is
now made to FIG. 2, which is a perspective view of a package
embracing said invention. As can be seen in the Figure, the
secondary retention end panels, 30 and 30', assuume a position
along the ends of the erected carrier and extend substantially
perpendicular to and between side panels, 2 and 2'. As before
mentioned the slots formed by the cut lines 7--7, 7'--7', 4--4 and
4'--4' form the primary means of retaining the articles in the
carrier. The secondary retention end panels, 30 and 30', are moved
into place by folding the triangular folding panels into an
overlapping relationship and moving the overlapping panels into a
juxtaposition with respect to the side panels, 2 and 2'. This is
best seen by reference to triangular folding panels, 37 and 38, in
the Figure. As can be seen, triangular folding panel, 37, is
rotated about scored fold line, 32, and extended inwardly
therefrom. At the same time, triangular folding panel, 38, is
pivoted about scored fold line, 39, and extends outwardly therefrom
when panels, 37 and 38, become adjacent. As can also be seen in the
Figure, panels, 37 and 38, assume a juxtaposition with respect to
side panel, 2'. It will be appreciated that triangular folding
panels, 33 and 34, 33' and 34', and 37' and 38', assume similar
positions although not clearly shown in the Figure. In general, the
elevation of the secondary retention end panels, 30 and 30', can be
varied over the entire height of the carrier; however, it is
preferred that the secondary retention end panels be positioned so
as to contact the carried articles at or near the central portion
thereof since in that position the maximum protection against
bottle dropout is attained and the carrier is able then to
accommodate various sizes and shapes of bottles or cans. It will be
appreciated that the elevation of the secondary retention end
panels can be varied by varying the size and angle of the
triangular folds. Moreover, the width of the secondary retention
end panels may be varied over a wide range; however, a panel of
about one (1 inch) inch height is adequate for most
applications.
As can also be seen in the Figure, margins, 5 and 5', overlap so as
to enable the engagement of the various locking elements. The
locking mechanism as illustrated is identical with that disclosed
and claimed in U. S. Pat. No. 3,098,583 which was granted in July
23, 1963 to Earle C. Sherman and Raymond A. Cote. As illustrated,
locking tabs, 11--11, engage locking bars, 18--18. This is
accomplished by rotating flap, 8, about scored fold lines, 9--9, so
as to move the locking tabs out of the plane of the margin, 5, and
then rotating the flap, 8, back to its original position and below
margin, 5'. It will be appreciated that the locking bars, 18--18,
were rendered accessible by rotating the locking flap, 14, out of
the plane of margin, 5', prior to engagement. After the locking
elements are engaged, the locking flap is margin, then rotated back
into a position below flap, 8, and the locking tabs, 16--16, pushed
into engagement with locking bars, 13--13. The operation of this
locking mechanism is clear from the disclosure of U. S. Pat. No.
3,098,583, and the disclosure of which is incorporated herein by
reference to the extent necessary. As can also be seen in the
Figure, separating tabs, 22--22, are rotated so as to extend
upwardly, thereby preventing direct contact between the parallel
rows of articles packaged in said carrier. Similarly, separating
tabs, 25--25, are rotated out of top panel, 1, and extend
downwardly from the top of said carrier, thereby affording
separation between the parallel rows of carried articles at the top
thereof.
It is believed that the manner in which the secondary retention end
panels, 30 and 31, are positioned and held in place will be clear
by reference to FIG. 3, which is a partial top view of a carrier
such as that shown in FIG. 2 with cans placed therein and with a
portion of the top cut away. As can be seen in the Figure, the
secondary retention end panel, 30, will contact the terminal
articles, 41--41, packaged in said carrier at a point below the
chimes thereof, and hence, in the central portion of said articles.
At the same time the primary retention means will retain the chimes
of the cans placed in the carrier. As can also be seen in the
Figure, folding panel, 37, contacts side panel, 2', and is
overlapped by triangular folding panel, 38, which is pivoted about
scored fold line, 39. The end panel is thus held in place by the
force exerted by the carried article, 41, on triangular folding
panels, 37 and 38, and side wall, 2'. It will be appreciated that
the internal structure with respect to the other triangular folding
panels is identical to that shown.
The elevation of the triangular folding panels is illustrated in
FIG. 4 which is a sectional view of the carrier as shown in FIG. 3
taken along lines, 4--4, with certain irrelevant detail omitted. As
can be seen in FIG. 4, triangular folding panels, 33 and 37,
contact the side panels, 2 and 2', respectively, over the full
height of said triangular panels. As can also be seen in the
Figure, the triangular folding panels are held firmly in place by
the carried articles in the area of overlap which is illustrated by
the height of scored fold lines, 35 and 39.
From the foregoing it can be seen that there has been provided a
new and improved wrap-around article carrier which has formed
thereon secondary retention panels which are positioned at the
central portion of the cans or bottles contained in the carrier.
With the secondary retention panels thusly positioned the carrier
is able to accommodate varying sizes and shapes of bottles or cans
while offering maximum protection from bottle dropout. The
secondary retention means acts in conjunction with the standard
primary retention means to offer a positive two fold protection
from bottle dropout.
Although the present invention has been described and illustrated
by reference to a particular embodiment, it will be readily
apparent that the present invention lends itself to various
modifications which will be obvious to those skilled in the art.
Accordingly, reference should be made solely to the appending
claims to determine the scope of the invention.
