ARTICLE CARRIER
Abstract
An article carrier of the basket style comprises medial handle
structure, riser panels secured to the ends of the handle
structure, end walls secured medially thereof to the riser panels,
side walls foldably joined at their end edges to the corresponding
end edges of the end walls, at least one partition element
interconnecting each side wall and the handle structure to form a
plurality of article receiving cells on each side of the handle
structure, bottom panels foldably joined to the bottom edges of the
side walls respectively and arranged to be interconnected to form a
composite bottom panel, the dimensions of the cells on each side of
the handle structure in a direction longitudinally of the carrier
being less than the diameters of the packaged articles so that the
sum of the diameters of the articles packaged and of the partition
elements in each row of cells is greater than the length of the
handle structure and of each side wall. The carton is formed
completely except for the composite bottom panel and is lowered
from above into enveloping relationship relative to a group of
articles to be packaged, the articles having upwardly tapered upper
portions to facilitate loading and preferably the partition
elements being extensible whereby relative movement in a direction
which is transverse to the carrier handle is accommodated between
the side walls and the handle structure to facilitate manual access
to a hand gripping opening formed in the handle structure.

Claims
The embodiments of the invention in which an exclusive property or
privilege is claimed are defined as follows:
1. A package comprising a plurality of articles arranged in
side-by-side rectilinear relation and each having an upwardly
tapered upper portion and a lower portion of greater transverse
dimension than the upper portion and carrier structure including a
handle, riser panels connected to the ends of said handle and
extending downwardly therefrom, end walls secured medially thereof
to said riser panels at each end of the carrier, a pair of side
walls foldably joined at their end edges to corresponding end edges
of said end walls, at least one partition element interconnecting
each side wall and said handle structure to form a plurality of
article receiving cells on each side of said handle structure, said
partition elements being adjoined at at least one end through a
carton panel having an adjacent curved slit to render said
partition elements extensible thereby to accommodate outward
movement of said side walls relative to said handle structure, the
length of said handle structure and of said side walls and the
width of said end walls being such that the cells are oversized
relative to the upper portion of the articles and undersized
relative to the lower portions of the articles to such an extent
that a gripping force is applied to the lower portions of the
articles when loaded into the carrier due to tension stress in said
handle structure, said side walls and in said end walls, an
initially open bottom panel foldably joined to the bottom edge of
each of said side walls, and locking tabs and locking apertures
formed respectively in said bottom panels and interconnecting said
bottom panels after the articles are loaded into the carrier
through the open bottom thereof.
Description
Known article carriers of the basket style are constructed and
specially adapted for machine drop loading wherein the articles to
be loaded into the carrier are automatically dropped from above the
carrier into the respective article receiving cells thereof. Of
course the cells in such a carrier must exceed in size in any
transverse direction the corresponding transverse dimension of the
articles to be packaged in order to insure effective loading.
It is also known that basket style article carriers may be
constructed with undersized cells whereby the resultant package is
in effect a tight unitary article enveloping structure which
permits little if any relative movement between the packaged
articles. Such tight packages are not feasible for use in
conjunction with automatic droploading operations for obvious
reasons and hence have not met with substantial practical
acceptance.
It has also been suggested that certain advantages may attend
loading basket style carriers by introducing the articles from an
open bottom or conversely by lowering a basket style carrier on to
an assembled group of articles from above, the carrier bottom being
open during such loading operations and then being closed following
envelopment of the articles. Such known procedures have not been
employed in conjunction with tight packages in so far as is
known.
According to this invention a basket style carrier is completely
formed except for its bottom structure and the transverse
dimensional relationship between the cells of the carrier and the
diameter of the articles to be packaged is such that the carrier
cells when filled are tightly disposed about the articles, the
tight finished carton being effective to prevent jostling of the
articles and being made possible due to the fact that the packaged
articles have upwardly tapered upper portions which facilitate
guiding the carton into article enveloping relationship even though
the cells are undersized. Of course a tight package can be
constructed of material such as paperboard which is substantially
lighter in weight than would otherwise be required. In accordance
with a feature of the invention, the partition elements are
extensible so as to facilitate manual grasping of the carrier
handle and carrying of the carrier by affording hand gripping space
immediately adjacent the handle structure.
For a better understanding of the invention reference may be had to
the following detailed description taken in conjunction with the
accompanying drawings in which FIG. 1 is a perspective view of a
completely set up but unloaded carton formed according to the
invention; FIG. 2 is a plan view of the blank from which the carton
of FIG. 1 is formed; FIGS. 3, 4 and 5 depict sequential gluing and
folding operations through which the blank of FIG. 2 is manipulated
to form the completed and collapsed carrier as shown in FIG. 5, the
bottom wall being left open as shown in FIG. 5; FIG. 6 is a side
view showing a step in the loading of the carrier whereby the
carrier of FIG. 5 is first set up and then lowered downwardly from
above into enveloping relationship relative to a group of articles
to be packaged; and in which FIG. 7 is a cross-sectional view taken
along the line designated 7--7 in FIG. 6.
In the drawings the numeral 1 designates a side wall of the carrier
to the bottom edge 2 of which a bottom panel 3 is foldably joined.
A plurality of locking tabs 4 are formed along one edge of bottom
panel 3. End wall panel 5 is foldably joined to side wall 1 along
fold line 6 while end wall 7 is foldably joined to side wall 1
along fold line 8.
For the purpose of rendering the carton corners readily conformable
with the packaged articles, a pair of weakened lines 9 and 10 are
formed in side wall 1 near the end edges 6 and 8 thereof and
weakened lines 11 and 12 are formed in end wall panels 5 and 7
respectively. In like fashion weakened lines 13 and 14 are formed
in end wall panels 5 and 7 near the opposite edges thereof.
For interconnecting the tray portion of the carrier with its handle
structure, a pair of riser panels 15 and 16 are foldably joined
along fold lines 17 and 18 to the inner edges of end wall panels 5
and 7 respectively.
The handle structure of the carton is of a composite construction
and includes a handle panel 19 foldably joined along fold line 18
to riser panel 16 together with a handle panel 20 foldably joined
to handle panel 19 along a medial fold line 21. Hand gripping
apertures 22 and 23 are formed in handle panels 19 and 20
respectively.
The handle structure of the carton is reinforced by reinforcing
panels 24 and 25 which are foldably joined to handle panels 19 and
20 along fold lines 26 and 27 respectively. Handle panels 24 and 25
are interconnected with each other along medial fold line 28 and
hand gripping apertures 29 and 30 are formed in handle panels 24
and 25 respectively.
For the purpose of subdividing the carrier on one side of the
handle into cells, one or more partition elements are provided.
Such elements are designated in the drawings by the numerals 31 and
32. Partition element 31 is foldably joined to side wall 1 along
fold line 33 and to handle panel 19 along fold line 34. Similarly
partition element 32 is foldably joined to side wall 1 along fold
line 35 and to handle panel 19 along fold line 36.
The opposite side of the carrier is of generally similar
construction and comprises a riser panel 37 which is foldably
joined to riser panel 15 along medial fold line 38 together with
riser panel 39 which is foldably joined to handle panel 20 along
fold line 40. End wall 41 is foldably joined to riser panel 37
along fold line 42 while end wall 43 is foldably joined to riser
panel 39 along fold line 44. Side wall 45 is foldably joined along
fold line 46 to end wall panel 41 and along fold line 47 to end
wall panel 43.
For the purpose of rendering the corners of the carton yieldable,
weakened fold lines 48 and 49 are formed in side wall 45 and
similar weakened lines 50 and 51 are formed in end wall panel 41
while weakened lines 52 and 53 are formed in end wall panel 43.
The bottom panel 54 is foldably joined along fold line 55 to the
bottom edge of side wall 45. A plurality of retaining tabs 57 are
formed in bottom wall panel 54 and define openings for receiving
the locking tabs 4 as is obvious.
For dividing one side of the carton into a plurality of cells, a
partition element 58 is foldably joined to side wall 45 along fold
line 59 and to handle panel 20 along fold line 60. Similarly a
partition element 61 is foldably joined to side wall 45 along fold
line 62 and to handle panel 20 along fold line 63.
In order to form the carrier, an application of glue is first made
to the blank of FIG. 2 as indicated by stippling in that figure.
Thereafter reinforcing panels 24 and 25 are elevated and folded
toward the right along fold lines 26 and 27 to occupy the positions
depicted in FIG. 3.
An application of glue is then made to the blank as shown in FIG. 3
and as indicated by stippling in that figure. Thereafter end wall
panels 5 and 41 and the structure associated therewith are elevated
and folded toward the right along the fold lines 6 and 46 to occupy
the positions depicted in FIG. 4. This action causes the riser
panels 15 and 37 to become adhered to the inner surfaces of handle
panels 19 and 20 and of reinforcing panels 24 and 25.
Simultaneously riser panels 16 and 39 are elevated and folded
toward the left along fold lines 18 and 40 to occupy positions
indicated in FIG. 4. This action of course causes the riser panels
16 and 39 to adhere at the upper ends thereof to the inner surfaces
of handle panels 19 and 20. The carrier then appears as depicted in
FIG. 4.
In order to complete the folding and gluing operations, an
application of glue is made to the carrier as indicated by
stippling in FIG. 4 after which side wall 1 and portions associated
therewith which are disposed above the fold lines 21, 28 and 38 are
elevated and folded forwardly to occupy the positions depicted in
FIG. 5. FIG. 5 shows the carrier collapsed following completion of
manufacture by a carton manufacturer after which it is shipped to a
user such as a bottler.
The particular handle structure is shown as an example only. Of
course the invention is not limited to any particular handle
arrangement and handle structures other than that shown may be used
in practicing the invention.
In order to apply the carrier to a group of bottles, the carrier is
first partially set up by drawing the side walls apart and by
applying a force to the right hand edge of the carrier as shown in
FIG. 5 while holding the side walls 1 and 45 against sidewise
displacement. This action causes the walls to occupy the positions
depicted in FIG. 6 where the carrier is shown immediately above a
group of bottles "B" whose upper portions or necks "N" are upwardly
tapered. In FIG. 6 the carton is shown in the process of being
lowered downwardly into enveloping relationship with respect to a
group of bottles "B". After the side walls 1 and 45 reach their
lowermost positions, bottom wall panel 54 is folded inwardly
underneath the bottles "B" followed by inward folding of bottom
wall panel 3 to cause the locking tabs 4 to become aligned with
retaining tabs 57. Thereafter the locking tabs 4 are driven through
the openings defined by the retaining tabs 57 and the carrier is
then complete. Ordinarily the bottles rest upon a conventional
sword or the like and move continuously throughout the packaging
operation during the lowering and locking operations.
While the carrier of this invention may be loaded by hand or by any
suitable apparatus, the machine of U.S. Pat. No. 3,747,294 granted
July 24, 1973 is well adapted for use in loading the carrier of
this invention.
It will be understood that the invention is not limited to cartons
having locking tabs and that other means such as glue may be used
to adjoin the panels 3 and 54.
As has been explained and as is apparent from FIG. 7, the
transverse dimensions or nominal diameters such as "D" of the
bottles plus the thickness "T" of the partition elements such as 58
and 61 when added together constitute an appreciably greater
overall longitudinal distance than is the length of the handle
structure "S" or the length of either side wall 1 or 45. Thus the
cells are undersize and conformance of the corners of the cells is
necessary. Furthermore, the loading of the carrier is feasible with
the undersized cells due to the guiding action of the upwardly
tapered neck portions "N" of the bottles "B". It is also apparent
that the weakened lines such as 10, 12 and 14 facilitate
conformance of the corners of the carrier with the adjacent
bottles. Since the articles are gripped by the tension force of the
side and end walls and of the handle structure and partition
elements, very little load is applied to the bottom wall directly.
Furthermore from FIG. 7 it is apparent that the partition straps
58, 61, 31 and 32 bow outwardly to accommodate the oversized middle
bottle on each side of the handle structure "S". It is also
apparent that the resulting package is well adapted to be formed on
automatic high speed machinery and that when completely finished,
the tightness of the various carton panels insures that the
packaged bottles "B" are held immovable with respect to each other
and hence are protected against breakage due to jostling. In
addition, the tightness of the wrapper is possible due to the novel
method by which the package is formed and can be achieved with
minimum thickness of material such as paperboard.
The term "diameter" is sometimes used herein to denote the the
dimension "D" of the articles "B" and is an apt term where the
articles are circular in cross-section. The term is also used in
denote articles of different cross sectional configuration such as
hexagonal, octagonal and the like. If the number of faces is
increased sufficiently the article approaches a circular cross
sectional configuration.
To facilitate carrying and to provide hand room adjacent handle
structure "S", the partition elements such as 31, 32, 58 and 61 are
extensible. Toward this end, curved slits 64 and 65 are formed in
side wall 1 and in handle panel 19 near the fold lines 33 and 34
respectively as is best shown in FIG. 1. Similar slits are formed
near the ends of partition elements 32, 58 and 61 and serve to
accommodate relative transverse movement of the side walls and
handle structure.
