Abstract
A carton is provided with an automatic bottom panel, which extends from a side panel, and has two converging reverse-scored fold lines, which extend outwardly from the side panel. One end flap featuring an angled score is folded up from the automatic bottom panel and is glued to its body panel. Adhesive is applied only above the diagonal folding score, leaving the unglued section free to fold in reverse in the bottom formation. The other end panel bottom flap is folded inwardly in the box joining process and a second of that flap with another diagonal score is folded in reverse for glue application. As the main panels are folded in the final gluing process the reverse folded glued section adheres to the outside surface of the previously mentioned major bottom flap. As the carton is brought into square during the erection process, the flaps self-form into a solid, full-overlapping bottom.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is directed to cartons fabricated from paper, paperboard and/or corrugated paperboard. In particular, the present invention is directed to cartons that are configured for rapid set-up.
2. Prior Art
A rapid deployment carton is disclosed in Mueller, U.S. Pat. No. 5,887,782. The carton of Mueller '782 has an automatic bottom panel, which extends from a side panel, and has two converging reverse-scored fold lines, which extend outwardly from the side panel. End flaps are folded up form the automatic bottom and are adhesively connected to the end panels to form double ply side walls. One of the end flaps has a diagonal fold line, with portions of the flap above the diagonal fold line only being adhered to the end panel. The angles of the reverse scored fold lines are selected to allow the automatic bottom panel to be deployed from a folded position alongside the side and end panels to an assembled position perpendicular to the side and end panels, by displacing one side panel with respect to the other.
However, the Mueller '782 carton employs a bottom panel design which requires complex folding and gluing steps, in order to convert the raw die cut blank into a collapsed box.
It would be desirable to provide a carton, fabricated from paper, paperboard or corrugated paperboard, that has a self-deploying or at least partially self-deploying bottom structure, to enable rapid set-up from a collapsed configuration to a ready-to-use configuration.
It would further be desirable to provide such a carton, that has an improved bottom panel configuration, that provides for simpler folding and gluing of the bottom panels to the side walls, to create the collapsed carton.
These and other desirable characteristics of the present invention will become apparent in view of the present specification, including claims, and drawings.
SUMMARY OF THE INVENTION
The present invention comprises, in part, a carton, having a self-deploying bottom, comprising four serially connected rectangular sidewalls. Each sidewall is pivotably connected to the two sidewalls serially adjacent to it, so that the four sidewalls may be articulated between a substantially flattened orientation and an articulated set-up orientation, in which the four sidewalls are positioned in a rectangular configuration.
A first bottom panel is pivotably connected to a first one of the sidewalls, the first bottom panel having a first portion emanating along a first bottom panel first fold line from the first one of the sidewalls and a second portion, emanating from the first portion of the first bottom panel along a first bottom panel first fold line extending at an oblique angle to the first bottom panel first fold line.
A first deployment panel is pivotably connected to a second one of the side walls serially adjacent to the first one of the sidewalls, the first deployment panel having a first portion emanating along a first deployment panel first fold line from the second one of the sidewalls and a second portion, emanating from the first portion of the first deployment panel along a first deployment panel second fold line extending at an oblique angle to the first deployment panel first fold line.
The second portion of the first bottom panel and the second portion of the first deployment panel are pivotably connected along a first deployment panel third fold line extending substantially normal to at least one of the first bottom panel first fold line and the first deployment panel first fold line, when the carton is in its set-up configuration;
A second deployment panel is pivotably connected to a third one of the sidewalls, serially adjacent to the first one of the sidewalls, at an end of the first one of the sidewalls opposite the first deployment panel, the second deployment panel having a first portion emanating from the third one of the sidewalls along a second deployment panel first fold line, and a second portion emanating from the first portion of the second deployment panel along a second deployment panel second fold line.
An inside surface of the first portion of the first deployment panel is juxtaposed to and connected to an inside surface of the second one of the sidewalls.
An inside surface of the second portion of the second deployment panel is juxtaposed to and connected to an outside surface of the first bottom panel;
A second bottom panel is pivotably connected to a bottom edge of a fourth one of the sidewalls.
When the carton is in its flattened configuration, the first bottom panel is juxtaposed and parallel to the inside surface of the first sidewall, the first deployment panel is juxtaposed and parallel to the inside surface of the second sidewall, and the second portion of the second deployment panel is folded back upon the first portion of the second deployment panel;
Upon movement of the carton from its flattened configuration to the set-up configuration, the second portions of the first and second deployment panels pull the first bottom panel down to a position perpendicular to the sidewalls when the sidewalls attain their rectangular set-up configuration.
The second bottom panel is subsequently folded down to a position juxtaposed and parallel to and above the first bottom panel.
In a preferred embodiment of the invention, the carton further comprises at least two interlocking top panels emanating from top edges of at least two of the sidewalls, for creating a closure of the top of the carton.
In a preferred embodiment of the invention, the carton further comprises a top panel emanating from the top edge of each of the sidewalls, wherein at least two of the top panels have free edges operably configured to interlock with one another to provide a closure of the top of the carton.
Preferably, the first bottom panel and the first deployment panels are contiguous and monolithically formed. In an embodiment of the invention, the second bottom panel is discontiguously formed with respect to the first bottom panel. In an alternative embodiment of the invention, the first bottom panel, the first deployment panel and the second deployment panel are contiguously and monolithically formed.
The present invention also comprises, in part, a carton, having a self-deploying bottom, comprising four serially connected rectangular sidewalls.
Each sidewall is pivotably connected to the two sidewalls serially adjacent to it, so that the four sidewalls may be articulated from a substantially flattened orientation, to a set-up orientation, in which the four sidewalls are positioned in a rectangular configuration;
A first bottom panel is pivotably connected to a first one of the sidewalls, the first bottom panel having a first portion emanating along a first bottom panel first fold line from the first one of the sidewalls and a second portion, emanating from the first portion of the first bottom panel along a first bottom panel first fold line extending at an oblique angle to the first bottom panel first fold line.
A first deployment panel is pivotably connected to a second one of the side walls serially adjacent to the first one of the sidewalls, the first deployment panel having a first portion emanating along a first deployment panel first fold line from the second one of the sidewalls and a second portion, emanating from the first portion of the first deployment panel along a first deployment panel second fold line extending at an oblique angle to the first deployment panel first fold line.
The second portion of the first bottom panel and the second portion of the first deployment panel are pivotably connected along a first deployment panel third fold line extending substantially normal to at least one of the first bottom panel first fold line and the first deployment panel first fold line, when the carton is in its set-up configuration.
A second deployment panel is pivotably connected to a third one of the sidewalls, serially adjacent to the first one of the sidewalls, at an end of the first one of the sidewalls opposite the first deployment panel, the second deployment panel having a first portion emanating from the third one of the sidewalls along a second deployment panel first fold line, and a second portion emanating from the first portion of the second deployment panel along a second deployment panel second fold line.
The second portion of the second deployment panel is pivotably connected to the first bottom panel, along a second deployment panel third fold line to a third portion of the first bottom panel, that is in turn, connected to the first portion of the first bottom panel along a third bottom panel fold line that extends obliquely to the first bottom panel first and second fold lines.
An inside surface of the first portion of the first deployment panel is juxtaposed to and connected to an inside surface of the second one of the sidewalls.
An inside surface of the first portion of the second deployment panel is juxtaposed to and connected to an inside surface of the third one of the sidewalls.
A second bottom panel is pivotably connected to a bottom edge of a fourth one of the sidewalls.
When the carton is in its flattened configuration, the first and second portions of the first bottom panel are juxtaposed and parallel to the inside surface of the first sidewall, the third portion of the first bottom panel is folded back over the first portion of the first bottom panel, the first deployment panel is juxtaposed and parallel to the inside surface of the second sidewall, and the second portion of the second deployment panel is folded back upon the first portion of the second deployment panel.
Upon movement of the carton from its flattened configuration to the set-up configuration, the second portions of the first and second deployment panels pull the first bottom panel down to a position perpendicular to the sidewalls when the sidewalls attain their rectangular set-up configuration.
The second bottom panel is subsequently folded down to a position juxtaposed and parallel to and above the first bottom panel.
In this alternative embodiment of the invention, the carton further comprises at least two interlocking top panels emanating from top edges of at least two of the sidewalls, for creating a closure of the top of the carton. Preferably, the carton comprises a top panel emanating from the top edge of each of the sidewalls, wherein at least two of the top panels have free edges operably configured to interlock with one another to provide a closure of the top of the carton.

128
is placed down on the outside surface of first wall panel
112
.
This results in a collapsed, fully glued carton blank
110
as shown in the lower left view of FIG.
3
. By pressing distally positioned corners I and II of blank
110
toward one another, corners III and IV are forced away from one another. As the four wall panels move from a flattened orientation, to a rectangular configuration, panel
126
unfolds and flattens, panel
144
pulls upon panel
142
, in turn pulling panel
140
from its position folded generally parallel to and against third wall panel
116
, to a position over and parallel to panel
144
, and perpendicular to first-through-fourth wall panels
112
,
114
,
116
and
118
. Finally, panel
120
is pushed down over panel
140
, to complete the set-up of carton
110
.
After carton
110
has been filled, the open top is closed, by first folding over second top flap
164
, and then first and third top flaps
160
and
166
, respectively. Finally, fourth top flap
170
is folded over, and tabs
172
and
174
are tucked into apertures
168
,
162
, respectively.
In the present invention, the amount of overlap of the bottom flaps may be full, as shown in
FIGS. 1-3
and
4
(left side), or partial as shown in
FIG. 4
(right side). By full overlap, it is meant that each of panel
20
(or
120
) and panel
40
(or
140
) extend substantially across the entire width of the bottom of the set-up carton. In other words, panels
20
and
40
each have a width that is almost equal to the side-to-side width of second wall panel
14
and fourth wall panel
18
. The alternative construction of
FIG. 4
b
, a partial overlap, panels
120
and
140
has a width (up and down direction in
FIG. 4
b
) that is substantially less than the (side-to-side) width of respective first and third wall panels
212
and
216
.
FIG. 4
also shows two other possible embodiments. In the lower left of
FIG. 4
, the sequence of panels along the length of the blank has been indexed by two panels (i.e., the unattached bottom panel and its corresponding length panel are the third panels, left to right, as opposed to being the leftmost panels). In the lower right of
FIG. 4
, a blank is formed, in which the length panel from which the unattached bottom panel emanates has been split in two (the seam for forming the carton is in the middle of a length panel, instead of being located at one of the corners of the erected carton). Aside from these differences, once formed into cartons, the operation of the cartons from these blanks is substantially the same as described with respect to the previously discussed embodiments.
The embodiments of
FIGS. 1-4
are provided with self-deploying bottoms, but panels
30
and
32
(or
130
and
132
or
230
and
232
), which remain vertical, only along side second wall panels
14
,
114
and
214
, respectively, after set-up of the respective embodiments, do not provide significant stacking reinforcement to the set-up cartons.
Accordingly,
FIGS. 5 and 6
illustrate a further alternative embodiment of the invention, in which stacking reinforcement is provided in addition to the self-deploying bottom of the previously described embodiments.
FIG. 5
illustrates an alternative embodiment of the present invention, in which the carton has inner reinforcing sidewall panels. Blank
310
comprises first wall panel
312
, second wall panel
314
, third wall panel
316
and fourth wall panel
318
. First flap
320
extends from the bottom edge of first wall panel
312
. Second flap
322
, comprising panels
330
and
332
, separated by fold line
334
and cut
331
, emanates from the bottom edge of second wall panel
314
. Third flap
324
, comprising panels
338
,
340
and
339
, separated by fold lines
341
and
337
, respectively, emanates from the bottom edge of third wall panel
316
. Fourth flap
326
, comprising panels
342
and
344
, separated by fold line
345
and cut
343
, emanates from the bottom edge of fourth wall panel
318
. Die cut holes
336
may be provided at the roots of fold lines
334
and
345
, to alleviate bunching of the corrugated material, during articulation of the carton. Second flap
322
, third flap
324
and fourth flap
326
are contiguously formed. Strip
328
is provided, for adhesive attachment to an outer or inner surface of first panel
312
.
To form a carton from blank
310
, second flap
322
, third flap
324
and fourth flap
325
are folded up and over second wall panel
314
, third wall panel
316
, and fourth wall panel
318
, respectively. The juxtaposed surfaces of second wall panel
314
and panel
330
are adhesively affixed to one another, as shown in the upper left of FIG.
6
. Similarly, the juxtaposed surfaces of fourth wall panel
318
and panel
344
are adhesively affixed to one another, as shown in the upper left of FIG.
6
. First wall panel
312
, with panel
320
folded up, is folded about fold line
346
, to overlie second wall panel
314
and a portion of third wall panel
316
, and folded up flaps
322
,
324
, respectively. Fourth wall panel
318
is folded over, about fold line
348
Prior to folding fourth wall panel
318
over, adhesive is also applied to the upwardly facing side of strip
328
, so that when fourth wall panel
318
is folded about fold line
348
, strip
328
is placed down on the outside surface of first wall panel
312
. This results in the flattened, collapsed carton
310
of the lower left of FIG.
6
.
To set-up the carton, the distal edges are pressed toward one another, as in the other embodiments, panels
342
and
332
pull on panels
339
,
338
respectively, to, in turn, pull down panel
340
. When the wall panels reach a rectangular configuration, panel
324
becomes flattened, and permits panel
320
to be pushed down on top of it to complete set-up of the carton.
The embodiment of
FIGS. 5 and 6
is provided with enhanced stacking strength in that panels
330
and
344
are substantially whole, extending completely from top to bottom alongside panels
314
and
318
, respectively, thus providing that two of the side walls of the carton have a double thickness.
While the carton of
FIGS. 5 and 6
is shown, without top panels, it is understood that a further alternative embodiment, incorporating the top panels of the embodiments of
FIG. 3
, may be provided, and would be within the scope of the present invention.
The foregoing description and drawings merely explain and illustrate the invention, and the invention is not limited except insofar as the appended claims are so limited, as those skilled in the art who have the disclosure before them will be able to make modifications and variations therein without departing from the scope of the invention.
