OPENING FEATURE FOR BOTTLE CARRIER
Abstract
A carrier for a plurality of similar articles such as bottles is
formed from a unitary blank of foldable paperboard to provide a
carton sleeve having opposed side walls and opposed end walls, the
side walls extending over the tops of the articles and being joined
to define a top wall. The end walls have indented upper portions
maintained in position by gusset elements flanking the inner sides
of upper portions of the side walls. A line of weakness extends
from each edge of the top panel in convergent directions to
intersect at a pull tab in one of the side walls, there by defining
a tear panel which when removed exposes the tops of the bottles for
easy removal from the carrier.

Claims
I claim:
1. A carrier carton, for packaging a plurality of similar articles,
formed from a unitary blank of foldable paperboard, comprising: a.
opposed pairs of end and side walls foldably joined by fold lines
to form a rectangular carton structure i. said opposed pair of side
walls each having a height equal to the height of said articles;
ii. said opposed pair of end walls, each being hinged at opposite
sides thereof to respective side walls and having a height equal to
the height of said side walls; b. each of said end walls including
an upper portion defined by; score lines therein extending in
converging directions from adjacent corners of said rectangular
carton structure; ii. gusset panels defined by said score lines and
said fold lines whereby each of the upper areas of said end walls
may be folded inward; c. each of said side walls extending in
convergent directions with respect to each other near the upper
portions thereof upon folding of said gusset panels; d. a flat
bottom wall including a pair of panels hinged to lower edges of
respective side walls and secured to each other in overlapped
relationship; e. a flat top wall parallel to said bottom wall and
including a pair of panels hinged to upper edges of respective side
walls and secured to each other; f. a continuous tear panel in said
top wall and the upper portion of one of said side panels; i. said
tear panel being defined by a line of weakness extending from each
free edge of said top wall in a convergent direction to the other
line of weakness and intersecting in the upper portion of said one
side panel. ii. whereby upon opening of said tear panel the
structural integrity of said tubular structure is unimpaired.
2. A carrier carton according to claim 1 wherein a tear tab is
provided in said one side panel at one intersection of said lines
of weakness.
3. A carrier carton, for packaging a plurality of similar articles,
formed from a unitary blank of foldable paperboard, comprising: a.
opposed pairs of end and side walls foldably joined by fold lines
to form a rectangular carton structure; i. said opposed pair of
side walls each having a height equal to the height of said
articles; ii. said opposed pair of end walls being hinged at
opposite sides thereof to respective side walls and having a height
equal to the height of said side walls; b. each of said end walls
including an upper portion defined by; i. score lines therein
extending in converging directions from adjacent corners of said
rectangular carton structure; ii. gusset panels defined by said
score lines and said fold lines whereby each of the upper areas of
said end walls may be folded inward; c. each of said side walls
extending in convergent directions with respect to each other near
the upper portions thereof upon folding of said gusset panels; d. a
flat bottom wall including a pair of panels hinged to lower edges
of respective side walls and secured to each other in overlapped
relationship; e. a flat top wall parallel to said bottom wall and
including a pair of panels hinged to upper edges of respective side
walls and secured to each other; i. said flat top wall being free
from attachment from said end walls but having bearing contact with
upward folded in portions thereof; f. a continuous tear panel in
said top wall and the upper portion of one of said side panels; i.
said tear panel being defined by a line of weakness extending from
each free edge of said top wall in a convergent direction to the
other line of weakness and intersecting in the upper portion of
said one side panel; ii. whereby upon opening of said tear panel
the structural integrity of said tubular structure is
unimpaired.
4. A carrier carton according to claim 3, wherein a tear tab is
provided in said one side panel at an intersection of said lines of
weakness.
Description
PRIOR ART
This application is an improvement over the carrier structure
disclosed in Charles R. Helms application Ser. No. 30,917, filed
Apr. 22, 1970, now U.S. Pat. No. 3,627,193 for Carriers Formed From
Sleeves and Gusset Folded Bottom Closure Panels.
The structure according to the present invention comprehends a
bottle carrier which is substantially closed to light, and featured
by the provision of structure enabling the carrier to be opened
readily for removal of the contents thereof without destroying
completely its usefulness or integrity.
DRAWINGS
FIG. 1 is a plan view of a cut and scored blank for forming an
article carrier according to the present invention;
FIG. 2 is a perspective view of a completed carton formed from the
blank of FIG. 1;
FIG. 3 is a bottom view thereof; and
FIG. 4 is a sectional view looking in the direction of the arrows
4--4 of FIG. 2.
Referring to FIG. 1 there is shown a blank 10 for forming an
article carrier 10A for enclosing a group of bottles B and having
the opening feature according to the present invention. Blank 10
has a first lower enclosure flap 12 connected to a front panel 13
along a fold line 14. An opposing closure flap 16 is connected to a
back panel 17 along a continuation of the fold line 14. Closure
flap 12 has a glue patch GP thereon, so that closure flap 12 may be
placed into overlapping relationship with respect to closure flap
16 to close the bottom of the carton 10A seen in FIG. 2.
The first end panel 18 of carrier 10A has gusset flap elements 19
and 21 extending from the lower end thereof, these flap elements
being capable of being folded upon themselves along an individual
score line 20 in each. Gusset flap elements 19 and 21 are also
defined by a continuation of score lines 22 and 23 defining first
end panel 18 and a continuation of the score line 14 of front panel
13. Likewise, an opposed end panel 24 has gusset flap elements 26
and 27 foldably upon themselves along an individual score line 28
in each. One pair of such gusset flap elements is defined by the
continuation of a score line 29 and by a continuation of the score
line 14, while the other pair of such gusset flap elements is
defined by a continuation of a fold line 31 and a continuation of
the fold line 14.
Carton blank 10 includes a pair of inclined end panels 32 foldable
with respect to the first and second end panels 18 and 24 along a
fold line 33. Inclined end panels 32 converge towards each other,
and each is defined by converging gusset fold lines 34 and by
triangular gusset panels 36 also defined by a continuation of the
score lines 22, 23, 29 and 31 as the case may be.
An underlapping top flap 37 extends from the front panel 13, and is
foldable with respect thereto along a score line 35. An overlapping
top flap 38 which extends from the back panel 17 is foldable with
respect thereto along a continuation of the score line 35.
The overlapping and underlapping top flaps 38 and 37 are glued
together in a conventional gluing operation.
The two flaps 37 and 38 are each provided with fold-down tabs 39
defined by an essentially semi-circular cut line 40 and a score
line 41. When tabs 39 are folded down, they are in register and
define a pair of spaced finger holes for the transport of the
filled container 10A.
The top panels 37 and 38 may also be provided with converging lines
of weakness 42, which extend from each free edge of the top wall as
defined by top flap 38, the line of weakness commencing at the ends
of flap 38. These extend into the top portion of panel 17 and
terminate at their intersection in a tear tab 43. The precise
configuration of the line of weakness 42 or the tear tab 43 may be
as chosen, but irrespective of the form thereof they define a tear
panel 44, which when removed enables the contents of carrier 10A to
be removed readily.
It should be noted that the top panels 37 and 38 are free from
attachment from the end panels 18 and 24 so that the contents of
the carrier to be readily removed by the tearing at the lines of
weakness 42. Moreover, the top panels 37 and 38 rest upon the tops
of the end walls 18 and 24 to thereby provide a carrier which is
substantially light tight.
