Basket carrier with squaring tabs

A basket-style carrier designed to be automatically squared during fabrication. Squaring tabs at the lower ends of riser panels extend into slots in the end edges of the outer bottom panel flap to align the bottom panel flaps. The tabs are then folded over and glued to the outer face of the outer bottom panel flaps to strengthen the bottom panel.

FIELD OF THE INVENTION 
This invention relates to basket-style carriers for carrying articles such 
as beverage bottles. More particularly, it relates to a basket-style 
carrier capable of being more readily and efficiently squared up prior to 
forming the bottom panel. 
BACKGROUND OF THE INVENTION 
Basket-style carriers are commonly employed to package beverage bottles. A 
conventional arrangement includes a separate cell for each bottle and a 
center handle partition. Normally, the carriers are fabricated from a 
blank which is folded and glued into collapsed carrier form, after which 
the collapsed carrier is erected. In one design the bottom panel is 
integrally formed so that when the collapsed carrier is erected bottles 
may be inserted down onto the bottom panel through the open cells. In 
another design the bottom panel is formed by connecting the bottom panel 
forming flaps after the bottles have been inserted into the cells. The 
bottles are commonly inserted in this latter design by moving an opened 
carrier down over a group of stationary bottles, although the bottles may 
also be inserted by moving them down into the opened carrier. 
In either case, the carrier must be squared prior to forming the bottom 
panel, and the subsequently formed bottom panel must be maintained in 
squared condition. This can be a difficult task inasmuch as the loading of 
an opened carrier can leave the bottom panel forming flaps in a position 
which, if maintained, will result in an out-of-square bottom. Even though 
an out-of-square bottom can be made structurally sound, the carrier does 
not present as attractive an appearance as a carrier which has been first 
squared up and the various carrier elements connected so as to maintain 
the squared condition. 
Attempts have been made to provide bottom panel structures which overcome 
these problems. For example, U.S. Pat. No. 4,989,799 discloses 
basket-style carriers incorporating center keel tabs which extend through 
slots in the bottom panel flaps and are then folded back into the interior 
of the carrier through another slot in the outer bottom panel flap. This 
arrangement is intended to provide a square bottom panel by maintaining 
both bottom panel flaps in the desired relationship with each other and 
with the center handle panel. However, it requires the bottom panel flaps 
to be precisely aligned in order to receive the keel tabs. In addition, 
the tab folding operation requires relatively complicated machinery which 
can also slow the speed of the packaging line. 
Another problem with basket-style carriers is the lack of rigidity 
encountered in a typical design in which the center handle panel is 
connected only to the end panels and is spaced from the bottom panel. 
Attempts have been made to strengthen such a structure by providing center 
keel tabs which are adhered to the bottom panel. Examples of such a design 
are found in U.S. Pat. Nos. 4,915,218 and 4,919,261 which disclose keel 
tabs that are folded and glued to the inner face of one of the bottom 
panel forming flaps. Such an arrangement does not assist in squaring the 
bottom panel, but only strengthens it after the bottom panel has been 
formed. 
It would be highly desirable to be able to square the bottom panel of a 
basket-style carrier in a simple but reliable manner, while at the same 
time strengthening the bottom panel. 
BRIEF SUMMARY OF THE INVENTION 
The invention relates to basket-style carriers of the type comprised of 
opposite side panels connected to a bottom panel, opposite end panels 
connected to the side panels, a centrally located handle panel, an outer 
bottom panel flap foldably connected to one of the side panels and an 
inner bottom panel flap foldably connected to the opposite side panel. The 
outer bottom panel flap at least partially overlaps the inner bottom panel 
flap and is connected to it to form the bottom panel. In accordance with 
the invention, slots in the outer bottom panel flap adjacent each end 
panel are substantially aligned with the handle panel and receive squaring 
tabs connected to tab support means. The squaring tabs are folded back and 
are adhered to the outer face of the outer bottom panel flap. 
The squaring tabs cause the bottom panel to be squared by guiding the outer 
bottom panel flap into place as the slots in the bottom panel flap slide 
over the tabs. After the outer bottom flap is adhered or otherwise 
connected to the inner bottom panel flap, the squaring tabs are folded 
over and glued to the outer bottom panel flap to further strengthen the 
bottom panel. 
The slots are formed so that the edge over which the squaring tabs are 
folded is a straight edge parallel to the handle panel. The spacing 
between this edge and an opposite tapered edge facilitates entry of the 
tabs into the slots. In a preferred design, the squaring tab support means 
are riser panels connected to both the end panels and the handle panel. 
The carrier is readily formed from a compact integral blank. 
These and other features and aspects of the invention will be readily 
ascertained from the detailed description of the preferred embodiments 
described below.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring to FIG. 1, the basket-style carrier 10 of the invention includes 
a central handle panel 12 connected to riser panels 13 and 14 which in 
turn are connected to end panels 16. The end panels are connected to side 
panels 18, and the side panels are connected to bottom panel 19. 
Individual cells for receiving bottles or other articles are formed by 
straps 20 which extend from the side panels 18 to the handle panel 12. The 
handle panel includes a handle opening 22 and the carrier further includes 
corner cutouts 24 which extend into the adjacent side and end panels. This 
construction allows substantial portions of the end bottles in the carrier 
to be viewed, which is advantageous where the shape of the bottles 
contributes to brand identification. 
Each end panel 16 is formed from two end panel sections which are connected 
by fold lines to the adjacent riser panel 13 or 14. In the end panel 
facing away from the viewer, end panel sections 26 are connected to the 
riser panel 14 by fold lines 28. In the end panel facing the viewer, end 
panel sections 30 are connected to the riser panel 13 by fold lines 32. 
The bottom panel 19 is formed from two overlapping and interconnected 
flaps 33 and 34. The features of the invention which produce the desirable 
squaring effect and which contribute to the strength of the bottom panel 
are hidden in this view but are described in detail below. 
Referring to FIG. 2, wherein like reference numerals to those used in FIG. 
1 denote like elements, a blank 35 for forming the carrier is shown as 
being of generally rectangular shape except for outwardly extending bottom 
panel flaps. Preferably, the blank is formed from paperboard of the type 
conventionally used in the carrier industry. Centrally located at the 
right side of the blank are two similar outer handle panel sections 12 
connected together by a central fold line 36. Immediately to the left of 
the panel sections 12 are two similar inner handle panel sections 38, 
which are connected to each other by central fold line 40 and are 
connected to the panel sections 12 by fold line 42. Cutouts 44 in the 
inner handle panel sections are aligned with the handle cutouts 22 in a 
carrier formed from the blank, and the fold line 40 is an extension of the 
fold line 36. Cutout 46 between the fold lines 36 and 40 facilitates 
folding and determines the shape of the handle panel corners. Cutout 47, 
which interrupts the fold line 40, also facilitates the folding process. 
The outer ends of the straps 20 at the right of the blank are connected to 
the outer handle panel sections 12 by fold lines 48 while the outer ends 
of the straps at the left of the blank are connected to the inner handle 
panel sections 38 by fold lines 50. The inner ends of the straps are 
connected to the side panel sections 18 by fold lines 52. One of the side 
panel sections 18 is connected along fold line 54 to bottom panel flap 33, 
which is the outer or major flap in the bottom panel of a carrier, and the 
other side panel section is connected along fold line 56 to bottom panel 
flap 34, which is the inner or minor flap in a bottom panel. The side 
panel sections 18 are connected by fold lines 58 to end panel sections 26, 
which in turn are connected along fold lines 28 to riser panel flaps 14. 
Similarly, the side panel sections are connected at their opposite ends by 
fold lines 60 to end panel sections 30, which in turn are connected along 
fold lines 32 to riser panel flaps 13. Other than the edges of the handle 
panel sections formed by the cutout 46 and by fold lines 36, 40, 42 and 
28, the edges of the handle panel sections are formed by slits separating 
the handle panel sections from the cell divider straps and from the side 
and end panel sections, producing free edges when the blank is formed into 
a carrier. 
The carrier blank described thus far is typical of one form of blank for 
forming a basket-style carrier whose cells are separated by straps. In 
accordance with the invention, bottom panel squaring tabs 62 are connected 
by fold lines 64 at the ends of the riser panel flaps 13 and 14 
corresponding to their lower ends in a carrier formed from the blank. The 
squaring tabs are generally triangular in shape with a rounded apex. In 
addition, the outer bottom panel flap 33 includes slots 66 extending in 
from the side edges of the flap. As shown in greater detail in FIG. 3, 
each slot 66 is formed by a cutout having an edge 68 which is parallel to 
the fold lines 58 and 36. The opposite edge 70 forms an acute angle with 
the edge 68 and is rounded at its juncture with the outer edge of the flap 
33 as indicated at 72. A short transverse edge 74 connects the inner ends 
of the slot edges 68 and 70. 
It will be seen from FIG. 2 and the foregoing description that the blank is 
basically comprised of two identical half-blank sections differing only by 
the presence of the squaring tabs on one of the sections and the different 
size bottom panel flaps connected to each section. 
Still referring to FIG. 2, to form a carrier from the blank the inner 
handle panel sections 38 are coated with adhesive, as shown in stipple, 
and are then pivoted about fold line 42 onto the outer handle panel 
sections 12. This results in the interim form of blank illustrated in FIG. 
4, in which the handle panel sections are adhered together. The next step 
is to apply adhesive to the areas of the riser panel flaps 13 and 14 shown 
in stipple in FIG. 4, and then to fold the end panel sections 30 about the 
fold lines 60. At this time the riser panel flaps 14 are also folded in 
about the fold lines 28. These steps adhere the riser panel flaps 13 and 
14 to the handle panel sections 38 and 12 to produce the interim form of 
blank shown in FIG. 5. 
The final sequence of the forming operation is to apply adhesive to the 
stippled areas of the folded riser panel flaps 13 and 14 and to the 
stippled areas of the inner and outer handle panel sections 38 and 12, as 
shown in FIG. 5, and to then fold the blank about the central fold lines 
36 and 40. This produces the collapsed carrier illustrated in FIG. 6, in 
which the end panels formed from the end panel sections 26 extend out from 
the side panels 18 in folded condition and the end panels formed from the 
end panel sections 30 are inwardly folded between the side panels. The 
squaring tabs 62 and the bottom panel flaps are still in unfolded 
condition at this point. 
To form a loaded carrier from the collapsed carrier of FIG. 6, the 
collapsed carrier is squared up by pressing the outer ends of the 
outwardly extending end panel sections toward the opposite end, as is well 
known in the industry. The opened carrier is then aligned with a group of 
bottles B to be packaged and lowered down over them, as depicted in FIG. 
7. Of course the carrier could be opened as described and bottles loaded 
into it by lowering them down into the carrier instead of lowering the 
carrier down over the bottles. During the bottle loading step the bottom 
panel flaps 33 and 34 and the squaring tabs 62 remain unfolded. After the 
carrier reaches it final position relative to the bottles, the bottom 
panel is formed by first folding in the inner bottom panel flap 34, then 
folding the outer bottom panel flap 33 to overlap the inner flap. As the 
outer bottom panel flap 33 moves into place the rounded corners 72 and 
tapered edges 70 of the slots 66 initially contact the squaring tabs 62 
and, in conjunction with the transverse edges 74, guide the bottom panel 
flap 33 to a position engaging the straight edge 68. This procedure places 
the bottom panel flaps in a position which forms a square bottom panel. 
The bottom panel flaps and the squaring tabs are illustrated in FIG. 8 
after the bottom panel flaps have been folded into place but before the 
squaring tabs have been folded, and are shown in FIG. 9 at their final 
position after being folded into place and glued to the outer bottom panel 
flap. This fixes the bottom panel in its squared condition and adds 
additional strength to the bottom panel. It further strengthens the entire 
carrier since the handle panel, through the riser panels and squaring 
tabs, are rigidly connected to the bottom panel. 
It is not necessary that the squaring tabs be connected to the blank on the 
same side as the outer bottom panel flap. The tabs can just as well be 
connected on the same side as the inner bottom panel flap. In either case, 
however, the slots 66 in the major bottom panel flap are arranged so that 
their straight edges 68 are the inner edges of the slots and the tapered 
edges 70 are the outer edges of the slots. Although the dimensions of the 
squaring tabs and the slots may vary according to the design of the 
carrier, the length of the slots should be such that the transverse edges 
74 are spaced apart a distance substantially equal to the distance between 
the bases of the tabs 62 at the fold lines 64. The edges 74 thus prevent 
the tabs 62 from moving to an out-of-square position, assuring that the 
bottom panel is properly formed. 
Although the bottom panel flaps have been described as being attached to 
each other by adhesive, bottom panel flaps which are interconnected by 
mechanical locks could be employed instead. It will be understood, 
however, that even in such an arrangement the squaring tabs are glued to 
the outer face of the outer bottom panel flap. 
It will be apparent that although the invention has been described in 
connection with a carrier designed for holding bottles, it applies equally 
to carriers designed to hold other types of articles instead. It is 
contemplated that the invention need not necessarily be limited to all the 
specific details described in connection with the preferred embodiments, 
but that changes to certain features of the preferred embodiment which do 
not alter the overall basic function and concept of the invention may be 
made without departing from the spirit and scope of the invention defined 
in the appended claims.
