Carrier and method
Abstract
The carrier has a central vertical support panel structure, and
a pair of foldable receptacles extending outwardly from opposite
sides of the vertical support structure. The receptacles have
automatically-opening bottom walls with symmetrical bottom panels
which overlap to even-out the strength of the bottom walls and
minimize areas of reduced strength. At least two opposed bottom
panels are shaped to interlock with one another to hold the carrier
open once it has been unfolded. Elongated, connected reinforcing
flanges strengthen the carrier in the vertical direction. Double
and triple-ply reinforcement panels are used to form a four or
six-ply handle structure for improved strength.

Description
[0001] This application is a continuation-in-part of U.S. patent
application Ser. No. 11/804,147, filed May 16, 2007, which is a
continuation-in-part of U.S. patent application Ser. No.
10/737,612, filed Dec. 16, 2003 and of Ser. No. 10/939,264, filed
Sep. 10, 2004. The disclosures of those patent applications are
incorporated herein by reference.
[0002] The carriers described in the above-identified pending U.S.
applications are superior in many respects to other carriers used
or proposed in the past. They can support relatively large loads,
they have relatively large areas available on which to place
advertising, they have bottom walls which open automatically when
the side edges of the folded carrier are pressed together, and they
have means for holding the carrier in its open, unfolded condition
automatically, without using the hand or a machine element.
[0003] Furthermore, the carriers are economical to manufacture,
requiring less material than many prior carriers, and, when folded,
occupy less surface area than many prior carriers so as to minimize
packaging size and shipping costs when the carriers are shipped in
folded form.
[0004] Despite the superior features of the foregoing carriers, it
is an object of this invention to provide a carrier, a method of
manufacturing the carrier, and a blank from which to fabricate the
carrier which has improved strength, ease of fabrication and use,
and is possible to manufacture even more economically.
[0005] In accordance with the present invention, the foregoing
objects are satisfied by provided a carrier with a central support
structure comprising at least one vertical support panel, a pair of
foldable receptacles extending outwardly from opposite sides of the
central support structure when the carrier is unfolded, and an
automatically opening bottom wall in each of the receptacles.
[0006] Preferably, the central support structure has two vertical
support panels each of which has an upper handle section which
extend above the foldable receptacles by a substantial distance and
has a hand hole near the upper edge. Each vertical support panel
has at least one, and preferably two foldable reinforcement panels
which are folded over onto and secured to each of said upper
sections.
[0007] Preferably, the vertical support panels are joined together
along a fold line at their upper edges.
[0008] The reinforced vertical support panels preferably are
secured to one another back-to-back. This gives a central support
structure with a two-ply thickness in the lower portion, and has a
four-ply, and preferably six-ply thickness in the upper handle
section, which makes the carrier very strong.
[0009] Advantageously, the reinforcement panels are formed from
material which otherwise would be scrap or waste material, so that
the reinforcement is provided without increasing the amount of
material used to make the carrier, and without extra fabrication
steps in the process of making the carrier.
[0010] Each bottom wall preferably includes flanges extending from
the lower edge of each of four side-walls for each of the
receptacles, with two opposed flanges, being shaped to interlock
with the other panel to hold the carrier open after it has been
unfolded.
[0011] Preferably, each of the two flanges has a lateral edge which
engages a lateral edge on the other during the unfolding of the
bottom structure whereby the two lateral edges engage one another
to hold the carrier open.
[0012] Preferably, each of the two interlocking flanges is, at its
widest, substantially as wide as the bottom in each receptacle, so
that the wide part of each flange extends substantially up to the
opposite side-wall, thus providing increased strength for the
bottom wall.
[0013] Preferably, the two flanges are symmetrical with respect to
one another to give a bottom of more nearly uniform strength over
the entire surface of the bottom wall.
[0014] Also, the two flanges are of complementary shape; that is,
one is wide where the other is narrow, etc.
[0015] In another aspect, the invention resides in a bottom wall
structure for a carrier, in which two opposed bottom flanges,
shaped to interlock with one another, are connected to other bottom
flanges which pull the two panels together to interlock them and
hold the carrier open when it is unfolded.
[0016] Preferably, the opposed flanges are of complementary shape,
overlap one another and form an upper surface for the bottom wall
in which the strength is distributed over the surface of the bottom
wall.
[0017] Also preferably, the bottom wall structure includes two
other flanges which are interconnected with one another so that the
bottom wall structures unfold automatically when the carrier is
unfolded, and the carrier can be fully opened by a single opening
movement.
[0018] Also in accordance with the invention, a blank is provided
for use in fabricating the carrier from a single piece of sheet
material. Preferably, the blank has a pair of vertical support
panels hinged together along a fold line at the top edge, with
three serially-connected receptacle wall sections connected at one
edge of each vertical support panel.
[0019] Each vertical support panel has a width substantially
greater than the receptacle wall sections secured to it, thus
leaving at least one, and preferably two additional panels secured
to one edge of each vertical support panel in its upper handle-hole
containing section.
[0020] Each additional panel is foldable onto one of the upper
handle-hole containing sections and has a handle hole to match the
handle hole in the upper section of the vertical panel when folded
over on it, thereby forming a multi-layer reinforced hand-hold
structure when the additional panels are secured together with the
vertical panels, preferably with adhesive.
[0021] Extending from the outermost edge of the last panel in the
series is an elongated attachment flange which is approximately as
long as the vertical support panels. The attachment flanges are
connected together at one end along a fold line.
[0022] When the carrier is fabricated, preferably, the wall
sections are folded relative to one another along fold lines
parallel to the vertical edges of the support panels, and the
elongated attachment flanges are secured to the panels along edges
to reinforce the panels and provide improved vertical lift strength
for the carrier.
[0023] The vertical support panels can be hinged together along a
fold line at the upper edges of the panels, and are left free from
one another so the panels can be swung apart. Preferably, the
panels are glued together back-to-back.
[0024] The invention also contemplates the provision of a carrier
using such elongated attachment flanges for connecting the vertical
support panels together, as well as reinforcing them.
[0025] The foregoing and other objects and advantages of the
invention will be set forth in or apparent from the following
description and drawings.

carrier shown in FIGS. 1 and 2, and
[0029] FIG. 4 is a top plain view of another blank used to

2.
GENERAL DESCRIPTION
[0030] The carrier 10 shown in FIGS. 1 and 2 includes a central
support structure 12 comprising two vertical support panels 14 and
16 hinged together along their top edges 13, and either adhered
together back-to-back, or, alternatively, left free to swing apart
from one another. Panel 16 is show only in FIG. 3. Reinforcement
panels 18 and 20 are glued to the upper portions of the support
panels 14 and 16. A handle hole 22 with a guard member 24 is
located in the center of each of the upper portions of the panels
14 and 16 to form a handle structure for lifting and carrying the
carrier and its contents.
[0031] A pair of foldable receptacles 26 and 28 extend outwardly
from opposite sides of the central support structure 12. Each
receptacle has four walls, one of which is formed by one of the
vertical support panels 14 or 16. The receptacle 26 has a series of
side-wall panels 30, 32, and 34 connected together along fold lines
and extending outwardly from the panel 14 when the carrier is
unfolded. Similarly, receptacle 28 has a series of side-wall panels
36, 38, and 40 extending outwardly from the panel 16.
[0032] Each of the receptacles has a bottom wall structure 42 or 44
which opens automatically when the folded-up carrier is pressed
together at the sides in the directions of the arrows 94 and 96
shown in FIG. 2 so as to quickly open and prepare the carrier for
receiving objects to be carried.
[0033] The carrier is shown in FIG. 1 in the position it takes
after the single motion pushing the edges of the folded blank
together. The bottom wall structure 42 or 44 is only partially
unfolded.
[0034] Each of the bottom wall structures 42 and 44 includes four
flanges, each secured to the lower edge of one of the four
side-walls of each of the two receptacles 26 and 28.
Bottom Structure
[0035] It is particularly advantageous that two opposed ones of
those flanges, such as the uppermost flanges 46 and 47 are recessed
in one section and are shaped to overlap and interlock with one
another so as to hold the carrier in the unfolded condition shown
in FIG. 1 without the use of one's hands or mechanisms.
[0036] The recesses are in opposite sections so that the flanges
overlap one another and each has a lateral edge. The lateral edges
are positioned so that they engage with one another such as at the
location 92 shown in FIG. 1 when the flanges 46 and 47 are
interlocked. This prevents the fiberboard material of which the
carrier is made from folding up and thus returning to its folded
condition. This holds the receptacles open to allow beverage
bottles or other objects to be loaded into the carrier and press
the bottom panels downwardly to flatten them.
[0037] Preferably, the flanges are symmetrical with respect to one
another, with respect to a longitudinal center line 51 and a
transverse center line 53 (FIG. 2) of each bottom wall. This helps
to even-out the bottom strength and minimize weak spots.
[0038] The bottom wall structures 42 and 44 are shown in FIG. 1
with the bottom panels, such as 46, 47, in an intermediate position
to which they are automatically pulled by the interconnection of
the bottom flanges to unfold the bottom wall structures
automatically. Thus, the panels 46 and 47 are shown in positions
above their lower-most positions which they will attain when a
beverage bottle is deposited on top of the panels.
[0039] Dividers 50 and 52 (as well as dividers for the other
receptacle 28, which are not shown in FIG. 1), are provided to
divide each receptacle into three compartments so that each
receptacle holds three bottles or other containers. Each of the
dividers 50, 52 has a glue tab 54 or 56 which is glued to the
surface of the panel 32 or 38 opposite the central support
structure.
[0040] The carrier 10 shown in FIGS. 1 and 2 is particularly well
suited for use as a six-pack carrier for beverage containers such
as bottles, etc., and is highly advantageous for use in bottling
plants where the carriers are filled with beverages to be shipped
to stores for sale.
Carrier Blank
[0041] Now referring to FIG. 3, as well as to FIGS. 1 and 2, each
of the four recessed flanges 46, 47, 48, and 49 has a tab extending
outwardly from one edge. The flanges 46 and 49 have a tab 82 or 122
extending from the short side edge of the flange.
[0042] The flanges 47 and 48 have tabs 84 and 86, respectively,
extending out of a longer side edge.
[0043] As it can be seen in FIG. 1, as well as FIG. 3, the tab 84
in the flange 47 fits into a slot 124 in the panel 32 near the
bottom edge of the panel, and the tab 82 fits into a slot 118 in
the bottom edge of the panel 30 when the panel 46 is pressed to its
lower-most position. Thus, the tabs on the flanges 46, 47, 48, and
49 fit into slots in the side-walls which hold those panels
downwardly when beverage containers or other objects are loaded
into the carrier and depress the panels downwardly. This helps hold
the bottom wall down solidly and minimize the chance that the
carrier will accidentally close after being opened.
Interlocking Flanges
[0044] As it is shown best in FIG. 3, each of the bottom flanges
46-49 has an outermost edge 98, 128, 104, or 138, and an inner
recessed edge 100, 130, 140, or 106. The corner of the recess is
rounded, and the recess forms a lateral edge 110, 132, 142, or 112.
At the opposite end of each flange a truncated triangular extension
102, 136, 146, or 108 is provided for extra strength.
[0045] Extending from the lower edge of each of the shorter
side-wall panels 30, 34, 36, and 40 is a triangular flange 76, 58,
64, or 70 with an attached glue tab 78, 60, 66, or 72 secured to
the first flange along a fold line 80, 62, 68, or 74.
[0046] As it is shown in FIG. 2, the glue tabs 60, 66, 72, and 78
are glued, respectively, to the flanges 49, 46, 47, and 48.
Advantageously, the glue tab is elongated, preferably to equal the
width of the widest portion of each of the flanges 46-49 so as to
extend as far as possible along the flange to which it is attached,
thereby strengthening the bottom structure of each receptacle,
without using excess material.
[0047] Optionally, a slit 134, 114, 144, or 116 can be provided at
the junction between the lateral edge and the inner edge of each of
the four flanges 46-49 to provide for more positive locking
engagement between the edges of adjacent panels.
[0048] As it is shown in FIG. 3, dividers 154 and 158 with glue
tabs 156 and 160 are provided for the receptacle 28 but are not
shown in either of FIGS. 1 and 2. Each of the dividers 50 and 154
is "nested" with another divider 52 or 158 to save material.
[0049] In FIG. 3, fold lines are indicated with the letter "F", and
areas to be glued, in one embodiment of the carrier, are marked
with the letter "G".
[0050] In accordance with another feature of the present invention,
elongated attachment flanges 148 and 150 are secured to the
outermost edge of the panels 34 and 36, respectively. The flanges
148 and 150 are attached together along the fold line 152, with a
notch 162 being cut in the material adjacent the fold line 152 to
match with the notch 164 at the upper edges of the vertical support
panels.
[0051] Since the flanges 148 and 150 are relatively wide, and are
approximately as tall as the vertical support panels, and are
secured together at 152, they provide exceptional reinforcement of
the edges of the vertical support panels, as well as secure anchors
for the ends of the side-wall panel series forming the side-walls
of the carriers. This further increase the load carrying capability
of the carrier.
[0052] The bottom construction of the carrier 10 is very
advantageous. Because the flanges 46, 47, and 48, 49 overlap one
another, are symmetrical and extend completely across the bottom
wall of each receptacle, the strengthening added by the flanges is
well distributed over the bottom wall so as to minimize any points
of weakness in the bottom wall.
[0053] Furthermore, when the bottom panels 46, 47 and 48, 49 lock
together edge-to-edge, this creates an extremely stable structure
to hold the carrier open and prevent it from relapsing in the
direction of the arrow 166 in FIG. 1 to fold up again due to the
natural resilience of the fiberboard material.
[0054] The tabs on the bottom panels and the slots near the bottom
edges of the side-walls of the receptacles help in holding the
bottom panels down and preventing the bottom from unfolding.
[0055] It should be understood that additional or differently
placed tabs and slots can be provided as desired instead of, or in
addition to, the tabs and slots shown in the drawings.
[0056] It should be understood that the carrier construction
described herein, with minor modifications, can be used highly
advantageously for carrying out food from a vending establishment,
such as a concession stand in a sports arena, a fast food
restaurant, etc. Carriers specially adapted for such use are shown
in my above-identified co-pending patent applications, and it is
unnecessary to describe them in detail here. However, in general,
the modifications usually would be to enlarge the compartments
receiving the beverage containers to receive large cups, reduce the
number of compartments, increase the height of the vertical support
panels, and supply top trays with slots in the bottom to receive
the vertical support panels, to enable the carrying of solid foods
in the top trays, using only one hand to carry everything.
[0057] As it is noted above, the vertical support panels 14, 16 can
be secured together back-to-back with glue, as indicated by the "G"
markings in FIG. 3. Alternatively, the vertical support panels 14
and 16 and their reinforcing panels 18, 20 can be secured together
only along fold lines 172, 170 so that the inside walls of the
panels 14, 16 can bear advertising, promotional materials, etc.,
which the customer can access by simply swinging the two
receptacles apart. This is a type of carrier sometimes referred to
as a "saddlebag" carrier.
[0058] If the saddlebag type of construction is selected, the
flange 148 is glued to the back side of panel 14, and the flange 15
is glued to the back side of panel 16. The flanges 150, 148, remain
attached at the fold line 152.
FIG. 4 EMBODIMENT
[0059] FIG. 4 shows another embodiment of the invention. It is
shown in the form of a blank 180 like the blank shown in FIG. 3,
with changes. The same parts bear the same reference numerals as in
FIG. 3.
[0060] A significant change in the blank 180 is the addition of
further reinforcing panels 182 and 184 made out of scrap material
shown in FIG. 3 at the ends of the reinforcing panels 18 and 20.
These further reinforcing panels do not add any materials costs
since they are made out of material which otherwise would be
scrap.
[0061] The panels 182 and 184 are secured to the ends of panels 18
and 20, respectively, along fold lines 188 and 190. The further
reinforcing panels also have elongated hand holes 22 of the same
size as the holes 22 in panels 14, 16 18 and 20. They are
positioned so as to align with the hand holes in panels 14, 16, 18
and 20 so as to form a single hand-hold for the carrier.
[0062] The additional reinforcement panels 182 and 184 are folded
over onto panels 18 and 20 and glued thereto, and then the
combination is folded over onto the upper portions of the vertical
support panels 14 and 16.
[0063] The vertical support panels 14 and 16 are folded along a
fold line 172 securing them together at their top edges.
[0064] Similarly the reinforcement panels 18, 20, 182 and 184 are
folded respectively, along lines 170 and 186.
[0065] The result of this change is a handle structure of six-ply
thickness. This supplies extraordinary strength where it is very
much needed, thus effectively enabling the carrier to withstand
both wet-tests and dry tests for strength while holding very large
loads.
[0066] Additional differences between the blank shown in FIG. 4 and
that shown in FIG. 3 are the use of glue tabs 194, 200, 208 and
214. These glue tabs are foldable along fold lines 192, 198, 206
and 212, respectively.
[0067] The narrow side walls 34 and 36 have semi-triangular shaped
extending flaps 204 and 216 respectively, and the side walls 30 and
40 have similarly shaped flaps 196 and 210. The four glue tabs are
glued to their adjacent flaps during the manufacturing process, to
form a strong, automatically opening bottom for each of the carrier
receptacles.
[0068] The resulting carrier looks substantially the same as the
carrier shown in FIGS. 1 and 2 but is even stronger than that
carrier, made so without any additional cost of materials.
[0069] The above description of the invention is intended to be
illustrative and not limiting. Various changes or modifications in
the embodiments described may occur to those skilled in the art.
These can be made without departing from the spirit or scope of the
invention.
