ARTICLE CARRIER AND BLANK THEREFOR
TECHNICAL FIELD
The present invention relates to a blank for forming a carrier and to the
carrier itself. More
specifically, but not exclusively, the invention relates to a blank for
forming carrier of the basket-
style wherein a medial partition divides the carrier into at least two cells,
and wherein a carrying
handle is provided which facilitates the transport of the carrier.
BACKGROUND
In the field of packaging it is known to provide basket-style article carriers
for carrying multiple
articles. Basket-style article carriers are well known in the art and are
useful for enabling
consumers to transport, store and access a group of articles for consumption.
These carriers
typically have a handle on top, such that the carrier mimics a conventional
basket, and typically
include a riser or medial partition from which the handle is fashioned. For
cost and
environmental considerations, such cartons or carriers need to be formed from
as little material
as possible and cause as little wastage in the materials from which they are
formed as possible.
Typically blanks for forming such carriers are arranged on a blank grid ¨ the
more blanks that
can be fitted onto the grid, the less material that is wasted. In certain
applications, a too close
arrangement of too tight nesting of blanks in a blank grid can be
disadvantageous. This is
because the closer fitting of the blanks makes it difficult to separate and
remove the cut blanks,
without tearing of the blanks, from a larger sheet of material from which a
plurality of individual
blanks are cut. Accordingly there is a balance between the total number of
blanks in a blank grid
that are cut simultaneously from a single sheet, and the time taken in
carefully removing those
blanks without tearing.
The present invention seeks to provide an improvement in the field of basket-
style article
carriers, typically formed from paperboard or the like.
SUMMARY
According to a first aspect of the present invention there is provided a blank
for forming a
basket-style carrier. The blank comprises a plurality of panels for forming
walls of the carrier
including a first side panel, a second side panel and a bottom panel. The
first side panel is
hinged to the bottom panel and the bottom panel is asymmetrical and has first
and second
opposed end edges. The first end edge is offset from a first end edge of the
adjacent first side

panel by a first distance. The second end edge of the bottom panel is offset
from a second end
edge of the adjacent first side panel by a second distance (D5). The first
distance is greater than
the second distance. The bottom panel may also comprise a beveled corner,
which beveled
corner is located at an intersection of the first end edge of the bottom panel
with a free side
edge of the bottom panel, which free side edge is opposite from a side edge of
the bottom panel
that is hinged to the first side panel.
The first end edge of the bottom panel is off-set, in other words, laterally
spaced from a notional
line passing through the first end edge of the first side panel. Similarly,
the second end edge of
the bottom panel is off-set by being laterally spaced from a notional line
passing through the
second end edge of the first side panel. By reducing the overall size of the
bottom panel and by
skewing its position to the side and making it "off-center", when adjacent
blanks are nested, a
greater space (cut-out region) is provided between adjacent blanks in the
grid, thus enabling
them to be more easily separated from one another and from the sheet of
material from which
they are struck, even when the number of blanks in the blank grid results in
tight and close
positioning of blanks. The non-rectangular, i.e. beveled corner further
increases the separation
between blanks and permits easier release of adjacent blanks from the blank
grid. By beveling
or otherwise shaping the an edge of the bottom panel a cut-out section between
adjacent
nested blanks in the blank grid may be shaped to lead into a cut line and
promote easy removal
of blanks along cut-lines and mitigate against unintentional tearing of corner
portions (or other
parts) of blanks, which it is known, can otherwise occur. Of particular
benefit is the provision of a
beveled corner, optionally angled in the region of 45 which creates a vertex
where converging
cut lines (for example the free edge of the bottom panel and the first end
edge of the bottom
panel) promote complete removal of blanks from the blank grid without tearing.
Optionally, the bottom panel is asymmetrical about a central axis of the first
side panel.
Optionally, the first side panel has a width defined as the distance between
first and second end
edges thereof, and wherein the bottom panel has a width defined as the
distance between first
and second opposed end edges thereof, the width of the bottom panel may be
less than the
width of the first side panel, and a notional half-way line of the bottom
panel may be off-set from
a notional half-way line of the first side panel.

Optionally, a center line of the blank is defined by a notional line through
the center of blank 10,
positioned half-way along the length of the blank.
A corner distance may be defined as the distance between a notional line
coincident with the
first end edge of the bottom panel and a notional line coincident with a
termination of the
beveled corner along said free side edge. A first center distance may be
defined as the distance
between the first side edge of the bottom panel and the centerline. The corner
distance may be
greater than or equal to the first center distance and the corner distance may
be less than or
equal to three times the first center distance.
Optionally, said first distance may be greater than the first center distance
and the first may be
less than two times the first center distance.
Optionally, a corner depth of the beveled corner is defined by the formula:
D3 = D4xtan(180 ¨ 9), wherein '0' is an angle defined by the free side edge
and the beveled
corner (59). Optionally, said angle '0' is greater than or equal about 100
and is less than 145 .
Optionally, the second side panel is spaced from and located opposite to the
first side panel,
and wherein a securing panel is hinged to the second side panel, the securing
panel is for
attachment to the bottom panel, and the securing panel is asymmetrical about a
central axis of
the adjacent second side panel and has first and second opposed end edges.
Optionally, the
first end edge of the securing panel is offset from a first end edge of the
adjacent second side
panel by a first distance. The second end edge of the securing panel may be
offset from a
second end edge of the adjacent second side panel by a second distance, and
the first distance
is greater than the second distance.
Optionally, the first end edge of the securing panel is offset from the first
end edge of the
adjacent second side panel by a similar distance to that first distance which
first end edge of the
bottom panel is offset from the first end edge of the first side panel.
Optionally, the blank is removed from a blank grid.
Optionally, the blank is cut from a larger sheet of material along with a
plurality of other similar
such blanks and wherein said other similar such blanks and said blank are
closely nested on
said larger sheet of material.

is generally "Z"-
shaped or at least comprises an angled portion. It is envisaged that the
bevelled corner of a
bottom panel may be provided by at least one angled straight line and in some
alternative
embodiments by more than one angled and contiguous cut lines. Additionally or
alternatively,
the bevelled corner in some arrangements may be provided by a curvilinear cut
line or an
arcuate cut line that leads into the corner of the cut-out region to allow the
blank to be peeled off
the blank grid optionally starting in that corner.

handle opening is defined in part by a cut line. Optionally, the third handle
opening is defined by
a third handle aperture A4 struck from first partition panel 26a.
Optionally, a portion of the second partition panel 26b forms a fourth handle
panel. The portion
of the second partition panel 26b which forms the fourth handle panel
comprises a fourth handle
structure A3 defined therein. The fourth handle structure A3 comprises a
fourth handle opening
A3. The fourth handle opening is defined in part by a cut line. Optionally,
the fourth handle
opening is defined by a fourth handle aperture A3 struck from second partition
panel 26b.
The first and second partition panels 26a 26b are hinged together along a
common top edge by
interrupted fold line 31. The fold line 31 may be oriented to extend in a
longitudinal direction in a
set up carrier 90. The fold line 31 may be substantially parallel to the
bottom panel 22 in a setup
carrier 90. The fold line 31 may substantially perpendicular to the fold line
29a which hinges the
second handle panel 30a to the second partition panel 25.
The blank 10 is arranged so as to comprise a first row or linear series L1 of
panels 24a, 16b, 14,
16a, 26a/28 and a second row or linear series L2 of panels 24b, 20b, 18, 20a,
26b. The first row
L1 of panels is hinged to the second row L2 of panels by the fold line 33
between the first and
second riser panels 24a, 24b; by the fold line 31a between the first and
second handle panels
30a, 30b; and by the interrupted fold line 31 between the first and second
partition panels 26a,
26b. The outer perimeter of the first and second linear series of panels L1,
L2 defines a general
footprint of the blank 10. Depending from the second side panel 14, and thus
from the first linear
series panels L1 is the securing panel 12. Similarly, on the opposite side of
the blank 10, the
bottom panel 22 extends from the first side panel 18 beyond the second linear
series L2.
In the present arrangement, it can be seen that the securing panel 12 is not
fully co-extensive
with the second side panel 14. Whereas a left-hand edge 69 of the securing
panel 12 is laterally
spaced from the fold lines 15b at a fourth distance, the right-hand edge 67 of
the securing panel
12 is laterally spaced further from the fold lines 15a at a third distance.
The third distance is
greater than the fourth distance. Stated differently, the securing panel 12 is
asymmetrical about
a center axis of the adjacent second side panel 14. To illustrate this, a cut
out region C2 is
shown in bold outline. The cut out region 02 is not part of the blank 10 and
is a cut and removed
portion.

Similarly, the bottom panel 22 is not fully co-extensive with the first side
panel 18. Whereas a
left-hand end edge 63 of the bottom panel 22 is laterally spaced from a
notional line aligned with
fold line 17b by a small distance (second distance D5; see Figure 8), the
right hand end edge 61
of the bottom panel 22 is laterally spaced from a notional line aligned with
the fold line 17a by a
greater distance (first distance Dl; see Figure 8). The first distance D1 is
greater than the
second distance D5. Stated differently, the bottom panel 22 is asymmetrical
about a center axis
of the adjacent first side panel 18. To illustrate this, a second cut out
regionC1 is shown in bold
outline. The cut out region Cl is not part of the blank 10 and is a cut and
removed portion. It is
removal of this cut out region Cl that gives the bottom panel 22 an asymmetric
shape. The
bottom panel 22 being asymmetric refers to it being asymmetrical about a
center axis of the
adjacent first side panel 18. This also results in the spacing between the
bottom wall 22 of the
assembled carrier 90 and the end wall 16a/20a being larger than the spacing
between the
bottom wall 22 of the assembled carrier 90 and the end wall 16b/20b (see
Figure 5). The
asymmetry of the bottom panel 22 whilst not aesthetically unpleasing is
unusual; furthermore,
the removal of additional material (cut out regions Cl and 02) increases
wastage, which is.
unusual. However, very beneficially, the blank 10 described and illustrated
herein provides for a
reduction in overall wastage of blanks 10 which are formed (by "cutting",
"blanking" or "striking")
from a larger sheet of material 'S'. See Figure 3 wherein an arrangement of
blanks are nested
on a sheet '5'.
As can be seen in Figure 3, the arrangement of six blanks 10a, 10b, 10c, 10d,
10e, 10f is a
close-fitting arrangement in order to maximize the number of blanks 10 that
can be cut from
such a single sheet '5'. In the layout shown, a bottom panel 22 of a first
blank 10a is positioned
back-to-back with a bottom panel 22 of a second blank 10b, such that "right-
hand" or "first-
edges" 61 are facing each other. A cut-out region '03' is disposed between the
adjacent blanks
10a, 10b. It is because of the additional cut-out region 'Cl' provided on each
blank 10a, 10b, in
other words, because of the asymmetrically arranged and re-sized bottom panel
22 with
beveled corner, that a "Z"-shaped cut-out region '03' is formed. By offsetting
the bottom panel
22 of nested blanks 10a, 10b, and cutting a bevel on the corner, a gap
(Canyon) is created that
gives the blanking grid room to break the carton blanks 10a, 10b, 10c, 10d,
10e, 10f apart
without ripping or tearing the corners of the bottom panels 22 of the blanks.
In this way the cut
out region or cut out area C3 between nested blanks 10a, 10b etc. is increased
and this
improves cutting speeds, the number of sheets per hour that can be cut and
processed is
increased, and the quality risks associated with prior art blanking grids are
reduced. The
CA 2976824 2017-08-21

- 11 -
increased and specifically shaped cut out region 03 between basket bottom
panels 22, with an
angle on a corner allows for the blanking grid to turn 90 degrees without it
being torn. Further
beneficially, the invention allows a cutting team to die-cut faster, with a
reduced set-up time,
thus reducing labor costs. In prior art blanking arrangements (as shown in
Figure 2) significant
labor of a die-cutting team and dozens of hours may be required to produce new
tooling to
make sure that it would not rip or tear the carton blanks during blanking. The
present invention
now allows for reduced set-up time, for faster die-cutting speeds to be used
and for longer
period and with a reduced risk of poor-quality.
For reference, Figure 2 illustrates a sheet of material S' from which six
known blanks 10a', 10b',
10c', 10d, 10e', 10f' are formed. In order to maximize the number of blanks
10a', 10b', 10c',
10d', 10e', 10f that can be struck from a standard sized sheet of material
`S", it is typical to nest
blanks 10' as shown, with a bottom panel 22' of a first blank 10b' being
disposed immediately
adjacent to a bottom panel 22' of a second blank 10a'. As shown, the bottom
panel 22 is
substantially fully co-extensive with the first side panel 18'. The bottom
panel 22' is
symmetrically positioned relative to the first side panel 18'. In other words,
a notional center line
of the first side panel 18' is in line with a notional center line of the
bottom panel 22'. The sheet
of material 'S shown in Figure 2 is a standard sized sheet, and six blanks
10a', 10b', 10c', 10d',
10e', 10f', each for forming a basket style carrier that can contain a 2 x 3
arrangement are
arranged thereon. However, the blanking grid can sometimes cause tearing of
the blanks when
the individual blanks are removed, and as described above this leads to a
reduction in quality,
slower production time and increased cost. The area of the cut out region 03'
between nested
blanks 10a', 10b', 10c', 10d', 10e', 10f is smaller than the new area of the
cut out region 03
between nested blanks 10a, 10b etc.
By forming the blanks 10 as show in Figure 1 and arranging them as shown in
Figure 3, the
basket carriers 90 produced therefrom are lower in cost, produced more quickly
and suffer far
less from low-quality issues.
Referring to Figures 1 and 3-7, and in particular Figures 6, 7 and 8 a set of
definitions and
dimensional relationships, which may be used in the specification and claims,
are listed which
help to characterize beneficial features of the new blank 10. It will be
understood that the
definitions are provided in relation to the blank(s) illustrated and that the
definitions are accurate
for the illustrated blank and that for blanks of other materials and sizes

Turning to the construction of the carrier 90 from the blank 10 the carrier 90
may be formed by a
series of sequential folding operations in a straight-line machine so that the
carrier 90 may not
be required to be inverted to complete its construction. Construction of the
blank 10 into a
.. carrier 90 is conducted in a usual manner and will therefore only be
described briefly.
Glue or other adhesive treatment is applied to the first partition panel 26a
in the region of the
third handle structure A4. Similarly, glue or other adhesive treatment is
applied to the second
partition panel 26b in the region of fourth handle structure A3. The first and
second handle
panels 30a, 30b are folded 180 about fold lines 29b, 29a respectively and
into face-contacting
and affixed relationship with the first partition panel 26a and second
partition panel 26b.
Glue G or other adhesive treatment is applied to the first securing tab 42a,
second securing tab
41b, third securing tab 52a, and fourth securing tab 51b. The blank 10 is then
folded about the
fold lines 25a, 25b so as to bring the first and second securing tabs 42a, 41b
into face
contacting relationship with the second side panel 14 and secured thereto. The
second and third
securing tabs 52a, 51b are brought into face contacting relationship with the
first side panel 18
and are secured thereto.
The blank 10 is folded about fold lines 23a, 23b, such that portions of the
first and second riser
panels 24a, 24b are brought into face contacting relationship with the second
and fourth end
panels 16b, 20b.
Glue or other adhesive treatment is then applied to the second riser panel 24b
and to the
.. second partition panel 26b.
CA 2976824 2017-08-21

-14-
Second securing panel 43a may then be folded about fold line 43b and glue or
other adhesive
treatment applied to second securing panel 43a.
The blank 10 is then folded about fold lines 31a, 33 and 31 to bring the first
partition panel 263
into face contacting relationship with the second partition panel 26 and
secured thereto. The first
riser panel 24a is brought into face contacting relationship with the second
riser panel 24b and
is secured thereto.
Glue or other adhesive treatment is then applied to bottom panel 22, in
alternative embodiments
glue may be applied to the securing panel 12 (see Figure 7).
To complete the construction of the blank 10, the bottom panel 22 is folded
about fold line 21,
such that the securing panel 12 is secured to the bottom panel 22. A flat
collapsed carrier is
thereby formed; the flat collapsed carrier can be opened into a basket-style
article carrier 90, as
shown in Figures 4 and 5. When the flat collapsed carrier is opened into a
basket-style carrier
90 by separating the first and first side panels 14, 18, the partition
structures are automatically
erected.
Once the carrier 90 is erected, the first and second handle panels 30a, 30b,
first and second
.. partition panels 26a, 26b, and first and second riser panels 24A, 24B form
a medial partition
structure that is disposed medially and substantially within the interior of
the carrier 90 defined
by the outer wall panels 18, 20b, 16b, 14, 16a, 20a. The medial partition
divides the interior of
the carrier 90 into two separate cells. The partition panels 40a, 40b 50a, 50b
further divide the
basket carrier into cells.
As can be seen best in Figure 5, the asymmetric bottom panel 22 is spaced
further from the
second end wall 16a, 20a than it is from the first end wall 16b, 20b. The
similar asymmetric
shape and size of the securing panel 12 enables a secure connection between
the securing
panel 12 and bottom panel 22. In spite of the beveled corner 59 and reduced
width of the
bottom panel 22 (because of the addition cut-out region 'Cl'), a sufficiently
secure connection
between the bottom panel 22 and securing panel 12 is ensured because a glue
area G1 in that
corner region (see Figure 7) is sufficiently large enough. Should dimension
'D4' and/or
dimension 'D3' be too small and/or dimension 'D2' too large, the security of
the bond between
the securing panel 12 and bottom panel 22 in that corner region may be
compromised and

accordingly, it is preferred if the corner distance (D4') is greater than or
equal to the first center
distance (D2') and that the corner distance (D4') is less than or equal to
three times the first
center distance ( D2 D4 < 3xD2 ). For similar reasons, additionally or
alternatively, it is
preferred if a corner depth (D3') of the beveled corner (59) which is defined
by the formula:
D3 = D4x tan(1 80 ¨19) , is controlled by the angle '0' (the angle defined by
the free side edge 'E'
and the beveled corner 59 is greater than or equal about 100 and is less than
about 145 .
It can be appreciated that various changes may be made within the scope of the
present
invention. For example, the size and shape of the panels and apertures may be
adjusted to
accommodate articles of differing size or shape. The carrier may be configured
and arranged to
package a different number of articles. In such embodiments, the carrier may
comprise an
alternative number of partition structures so as to separate adjacent
articles. In the first
illustrated embodiment, the side and end walls 20, 22, 16/18, 24/26 are
substantially of the
same height as the bottles contained within the carrier. In other embodiments,
a top cover may
additionally be applied to the carrier to more fully enclose the tops of the
articles, albeit utilising
the recess for accessing the carrying handle. In yet other embodiments, the
side and end walls
20, 22, 16/18, 24/26 are not substantially of the same height as the bottles
contained within the
carrier.
It will be recognised that as used herein, directional references such as
"top", "bottom", "base",
"front", "back", "end", "side", "inner", "outer", "upper" and "lower" do not
necessarily limit the
respective panels to such orientation, but may merely serve to distinguish
these panels from
one another.
As used herein, the terms "hinged connection" and "fold line" refer to all
manner of lines that
define hinge features of the blank, facilitate folding portions of the blank
with respect to one
another, or otherwise indicate optimal panel folding locations for the blank.
Any reference to
"hinged connection" should not be construed as necessarily referring to a
single fold line only;
indeed a hinged connection can be formed from two or more fold lines wherein
each of the two
or more fold lines may be either straight/linear or curved/curvilinear in
shape. When linear fold
lines form a hinged connection, they may be disposed parallel with each other
or slightly angled
with respect to each other. When curvilinear fold lines form a hinged
connection, they may
intersect each other to define a shaped panel within the area surrounded by
the curvilinear fold
CA 2976824 2017-08-21

- 16 -
lines. A typical example of such a hinged connection may comprise a pair of
arched or arcuate
fold lines intersecting at two points such that they define an elliptical
panel therebetween. A
hinged connection may be formed from one or more linear fold lines and one or
more curvilinear
fold lines. A typical example of such a hinged connection may comprise a
combination of a
linear fold line and an arched or arcuate fold line which intersect at two
points such that they
define a half moon-shaped panel therebetween.
As used herein, the term "fold line" may refer to one of the following: a
scored line, an
embossed line, a debossed line, a line of perforations, a line of short slits,
a line of half-cuts, a
single half-cut, an interrupted cut line, a line of aligned slits, a line of
scores and any
combination of the aforesaid options.
It should be understood that hinged connections and fold lines can each
include elements that
are formed in the substrate of the blank including perforations, a line of
perforations, a line of
short slits, a line of half-cuts, a single half-cut, a cut line, an
interrupted cut line, slits, scores,
any combination thereof, and the like. The elements can be dimensioned and
arranged to
provide the desired functionality. For example, a line of perforations can be
dimensioned or
designed with degrees of weakness to define a fold line and/or a severance
line. The line of
perforations can be designed to facilitate folding and resist breaking, to
facilitate folding and
facilitate breaking with more effort, or to facilitate breaking with little
effort.
