ARTICLE CARRIER
Abstract
An article carrier having top, bottom and sidewalls foldably
joined together to form a tubular structure for disposition about a
plurality of articles arranged in side-by-side rectilinear relation
in at least one row includes at certain corners of the carrier a
pair of divergent fold lines arranged to form a web panel which
effectively aids in retaining the articles in the wrapper against
dislodgment through the open ends thereof. Where apertures are
formed at the carrier corners for receiving portions of the
packaged articles to aid in retaining the articles, the web panel
formed by divergent fold lines also inhibits tearing of a blank and
thus further enchances package security.

Claims
The embodiments of the invention in which an exclusive property or
privilege is claimed are defined as follows:
1. An article carrier having spaced top, bottom and sidewalls
foldably joined together along transverse fold lines to form a
tubular structure disposed about a plurality of articles arranged
in side-by-side rectilinear relation in at least one row, and
wherein the improvement comprises a pair of outwardly diverging
fold lines extending to the adjacent end edges of the walls
adjoined by one transverse fold line from a vertex point spaced
inwardly from said end edges of said structure and disposed in
general coincidence with said one of said transverse fold lines to
define an article-retaining rupture-inhibiting unitary web panel
disposed in a single plane astride one corner of the carrier.
2. An article carrier according to claim 1 wherein an
article-gripping aperture is formed along said one transverse fold
line and where said vertex point is disposed immediately adjacent
the outer portions of the periphery of said aperture.
3. An article carrier according to claim 4 wherein said
article-gripping aperture is formed in an inwardly bevelled panel
forming a part of one of the walls adjoined by said one transverse
fold line.
4. An article carrier according to claim 1 wherein said web panel
is of a substantially triangular configuration and wherein the
single plane thereof is disposed in angular relation to the planes
of both of the walls adjoined by said one transverse fold line.
Description
The well-known corner weakness of article carriers may be overcome
at least partially by utilizing a pair of parallel fold lines which
are slightly offset from the corner of the package and which
interconnect the end edge of the package with an article-receiving
aperture formed at the package corner. Such an arrangement is
primarily adaptable for use in conjunction with the packaging of
cans having end flanges.
According to the present invention, divergent fold lines are
utilized at certain corners of a tubular package and serve to
improve substantially the article-retaining capability of the
tubular structure. Furthermore, such diverging fold lines when
utilized according to this invention in close proximity to corner
apertures, formed in the tubular structure for receiving portions
of the packaged items, significantly inhibit the tendancy of the
package to tear at the corners. The invention is useful in
packaging both cans and bottles but is particularly well adapted
for bottle packages.
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 an article carrier constructed
according to the invention;
FIG. 2 is a plan view of a blank from which the carrier depicted in
FIG. 1 is formed;
FIG. 3 is an enlarged fragmentary plan view of a portion of the
blank depicted in FIG. 2 and represents one form of the invention;
and in which
FIG. 4 is a perspective fragmentary view of another form of the
invention.
In the drawings the numeral 1 designates the top panel of a wrapper
in which a plurality of apertures 2, 3 and 4 are formed for
receiving the necks of the packaged bottles "B." Sidewalls 5 and 6
are foldably joined to top wall 1 along fold lines 7 and 8
respectively. A removable tear strip 9 is formed in sidewall 1 and
is of conventional construction. A fold line 10 is formed in
sidewall 6 and functions in a manner similar to tear strip 9 to
facilitate folding of the sidewalls in such manner as to cause the
sidewalls to conform generally with the exterior configuration of
bottles "B."
The panel formed at the lower edge of sidewall 5 and forming a part
thereof is a bevelled panel 11 which is foldably joined along fold
line 12 to the upper portion of sidewall 5 and in which
conventional corner apertures 13, 14 and 15 are formed. As is well
known, portions of the bottle "B" extend into the apertures 13, 14
and 15 which aid in retaining the bottles against dislodgment
through the open ends of the wrapper. As utilized herein, bevelled
panel 11 is considered as a part of sidewall 5.
The bottom wall of the carrier is a composite structure comprising
a pair of lap panels 16 and 17 which are foldably joined along fold
lines 18 and 19 respectively to the bottom edges of sidewalls 5 and
6.
In order to tighten the blank about a group of articles to be
packaged, a plurality of conventional tightening apertures 20 and
21 are formed in lap panel 16 and similar tightening apertures 22
and 23 are formed in lap panel 17. As is well understood in the
art, suitable machine elements enter the tightening apertures 20,
21 and 22, 23 and move in opposite directions underneath the
bottles "B" to tighten the blank about the article group.
Once the wrapper is tightened, it is locked by driving the locking
tabs 24 and 25 formed in lap panel 16 through the openings defined
by retaining tabs 26 and 27 formed in lap panel 17.
According to this invention, package security is substantially
enhanced by web panels formed at the lower corners of the package.
In the drawings, these web panels are generally designated by the
numerals 28-31. The web panels 28 and 30 are arranged with respect
to their associated apertures 13 and 15 in an identical manner
while the web panels 29 and 31 are of similar configuration and are
similarly related to the lap panel 17 and the sidewall 6.
As can best be seen in FIG. 3, web panel 30 is defined by a pair of
outwardly divergent fold lines 32 and 33 which intersect at a
vertex point 34. As is apparent from FIG. 2, vertex point 34 is
disposed in general alignment with the fold line 18 by which the
sidewall 5 is adjoined to lap panel 16. Web 30 and its fellow 28
are disposed in a single plane astride the lower left-hand corner
of the package as shown in FIG. 1 when the package is assembled and
when so disposed effectively aid in retaining the bottles "B"
against dislodgment through the open ends of the wrapper. Of course
such retaining function is in addition to that afforded in known
manner by the corner apertures such as 13, 14 and 15. In addition
to aiding in retaining articles within the wrapper, the web panels
28 and 30 also serve to inhibit tearing of the wrapper from
apertures 13 and 15 outwardly to the edge of the blank. Stated
otherwise, by substituting the divergent fold lines 32 and 33 for a
conventional continuation of the fold line 18, effective provision
is made for inhibiting tearing of the blank from apertures 13 and
15 along an imaginary fold line aligned with fold line 18 which of
course is not incorporated in the blank.
On the other side of the carrier web panels 29 and 31 are of
identical construction. For example, and as best shown in FIG. 4
web panel 31 is defined by a pair of divergent fold lines 35 and 36
which intersect at vertex point 37 disposed in alignment with fold
line 19. As is apparent from FIGS. 1 and 4, web panel 31 is
disposed at an angle to sidewall 6 and to lap panel 17 and is
astride the lower right-hand corner of the package as shown in FIG.
1. Web panel 31 and its associated fellow web panel 29 thus aid
significantly in retaining the bottles "B" against dislodgment
through the open ends of the tubular structure. Panels 29 and 31
are particularly effective since article-receiving apertures such
as 13, 14 and 15 are not incorporated along the right-hand corner
of the carrier and in general coincidence with the fold line 19.
The web panels 28-31 do not require any special treatment when the
carrier is formed since these web panels automatically assume their
angular positions when the bottom lap panels are folded at an angle
to their associated sidewalls.
