Description
BACKGROUND OF INVENTION
1. Field of the Invention
The present invention relates to disposable containers. More particularly, the present invention relates to containers for storing and dispensing a liquid.
2 Description of Related Art
With the increased use of what can be characterized as up-scale coffee at meetings and the like, there is a need to provide an economical service of supplying such coffee from an off site location. Typically, the coffee is ordered from a shop specializing in what can be characterized as “up-scale” coffee. Most usually, the coffee is delivered in relatively large vacuum containers. A problem with such delivery is that the vacuum containers must be retrieved by the coffee shop sometime after the conclusion of the consumption of the coffee contained therein. Typically what this entails is that a person from the coffee shop must coordinate a return trip to retrieve the vacuum containers. This trip is sometimes difficult to coordinate and certainly entails the time of at least one person to make the return trip to retrieve the empty vacuum containers. Alternatively, a fiber beverage container may be used to transport the coffee. Such beverage container is detailed in U.S. Pat. No. 5,715,992. The beverage container disclosed in the '992 patent has a major disadvantage from an ergonomic standpoint. The spout out of which the coffee is poured is located proximate the top side of the beverage container. Accordingly, the beverage container must be tipped through an exaggerated rotation in order for the coffee contained therein to be discharged through the upwardly disposed spout. Such tipping can expose the hand of the user to hot vapors emanating from the heated coffee. Further, in order to fully discharge the coffee contained in the container, the container must be tipped to an orientation in which the side having the spout disposed therein is substantially downward and horizontal. The action of the operator to effect such disposition is a nearly unnatural pouring action.
A further disadvantage of the container disclosed in the '992 patent is that a spout
9
must be fixedly internally disposed in the front
13
of the container. In the production process, the spout must be separately formed and then must be fitted to the container. After insertion of the spout, the container is no longer flat when in the folded disposition, making packing and shipping more difficult.
There is a need in the industry for a disposable container to transport beverages. Clearly an advantage of such a container is the fact that the container is readily disposable after use, thereby making a return trip by the provider unnecessary. The container should be ergonomically designed in order to readily facilitate the discharge of beverage therefrom. Further, it is desirable that such container substantially shield the hand of the user from any hot vapors emanating from the hot coffee.
SUMMARY OF THE INVENTION
The present invention substantially meets the aforementioned needs of the industry. Principally, by locating the spout from which the coffee is discharged proximate the bottom side section of the container, substantially all of the coffee contained therein may be discharged with virtually no tilting action on the part of the user of the container. Additionally, a shield is provided to substantially deflect hot vapors away from the hand of the user of the container.
The present invention is a disposable container that includes support structure that is shiftable between a disposable disposition and an erect disposition, the support structure defining an interior container space when in the erect disposition. The erect support structure has a bottom side section and a generally opposed and spaced apart top side section. A first end section extends between the bottom side section and the top side section and has an aperture defined therein, the aperture being disposed proximate the bottom side section. A second end section is spaced apart from the first end section and extends between the bottom side section and the top side section.
In a further embodiment, the present invention is a disposable container that includes support structure that is shiftable between a disposable disposition and an erect disposition, the support structure defining an interior container space when in the erect disposition. The erect support structure has a first end section, the first end section having an aperture defined therein, the aperture being disposed proximate a bottom side section. A bladder for holding a liquid is disposable in the interior container space.

DETAILED DESCRIPTION OF THE DRAWINGS
The disposable container of the present invention is shown generally at
10
in the drawings. The disposable container
10
includes a support structure
12
and, in a preferred embodiment, a bladder
14
. The support structure
12
is formed from a blank
16
as depicted in
FIGS. 3-5
. The blank
16
is erectable from the folded dispositions of
FIGS. 3-5
to the erect dispositions of
FIGS. 1 and 2
.
The blank
16
of the support structure
12
is foldable to define components comprising a center support section
18
, a first end support section
20
, a second end support section
22
, and a handle
24
. The center support section
18
includes a bottom side section
26
, first side sections
28
a
,
28
b
, second side sections
30
a
,
30
b
, and overlapping top side sections
32
a
,
32
b.
The first component of the support section
12
is the bottom side section
26
. The bottom side section
26
is preferably formed in a parallelogram shape defined by parallel, spaced apart fold lines
34
a
,
34
b
and parallel, spaced apart fold lines
36
a
,
36
b
. It should be noted that the fold lines
34
a
,
34
b
and
36
a
,
36
b
, as well as all the succeeding fold lines to be described, may be scored in the material forming the blank
16
in order to facilitate readily folding along such fold lines.
The first side sections
28
a
,
28
b
, are defined by the previously described fold lines
34
a
,
34
b
and the fold lines
38
a
,
38
b
, respectively. The fold lines
38
a
,
38
b
are preferably disposed in a parallel relationship with fold lines
34
a
,
34
b
. First side sections
28
a
,
28
b
are further defined by fold lines
40
a
,
40
b
. The fold lines
40
a
,
42
a
, and
40
b
,
42
b
are preferably not parallel, thereby defining first side sections
28
a
,
28
b
in generally trapezoidal shapes.
Outboard of first side sections
28
a
,
28
b
of the center support section
18
on the blank
16
depicted in
FIG. 3
, are second side sections
30
a
,
30
b
. The second side sections
30
a
,
30
b
are defined in part by fold lines
38
a
,
38
b
and
44
a
,
44
b
, respectively. Preferably, the fold lines
38
a
and
44
a
are disposed in a parallel relationship and the fold lines
38
b
and
44
b
are also disposed in a parallel relationship. The second side sections
30
a
,
30
b
are further defined by end margins
46
a
,
46
b
, respectively, and fold lines
48
a
,
48
b
, respectively. As with first side sections
28
a
,
28
b
, the second side sections
30
a
,
30
b
are trapezoidal in shape, the end margins
46
a
,
46
b
not being in a parallel relationship with respect to the fold lines
48
a
,
48
b
, respectively.
As depicted in
FIG. 3
, the overlapping top side sections
32
a
,
32
b
are disposed outboard from the blank
16
of the second side sections
30
a
,
30
b
. The overlapping top side sections
32
a
,
32
b
are defined by an edge margin
50
a
,
50
b
disposed in a parallel relationship to the fold lines
44
a
,
44
b
, respectively. The overlapping top side section
32
b
is additionally defined by the fold line
51
. The fold line
51
is collinear with the edge margin
50
b
. As will be described below, handle
24
is formed integral with the overlapping top side section
32
b
along the fold line
51
.
The ends of the overlapping top side sections
32
a
,
32
b
are defined by parallel and spaced apart fold lines
52
a
,
52
b
and fold lines
54
a
,
54
b
, respectively.
The second support section
12
component is the first end support section
20
. The first end support section
20
of the blank
16
is formed of front outer panel
60
, front inner panels
62
a
,
62
b
, and tabs
64
a
,
64
b.
The front outer panel
60
includes a hexagonal panel
66
. The hexagonal panel
66
is defined by fold line
36
a
and parallel, spaced apart fold line
71
. Hexagonal panel
66
is further defined by side margins
68
a
,
68
b
adjoining fold lines
70
a
,
70
b
. Outer panel tabs
72
a
,
72
b
are formed integral with hexagonal panel
66
along fold lines
70
a
,
70
b
, respectively. The tabs
72
a
,
72
b
are defined by an outer margin
74
.
A spout aperture
76
is defined in the hexagonal panel
66
. The spout aperture
76
is disposed proximate the bottom side section
26
adjacent to the fold line
36
a.
A tongue
78
is formed integral with the hexagonal panel
66
along fold line
71
. The tongue
78
has an upper portion
80
separated from a lower portion
82
by the fold line
83
. A slit
84
is defined in the lower portion
82
extending substantially between the fold line
71
and a semi-circular cutout
86
. The semi-circular cutout
86
has its base resting along the fold line
83
.
The first end support section
20
includes generally opposed inner panel halves
62
a
,
62
b
. The inner panel halves
62
a
,
62
b
are formed integral with the overlapping top side sections
32
a
,
32
b
, respectively, along the fold lines
52
a
,
52
b
, respectively. Each of the inner panel halves
62
a
,
62
b
has a cooperative cutout
90
a
,
90
b
respectively defined therein. As will be seen, the cutouts
90
a
,
90
b
cooperate to define an aperture that is generally the same size as the spout aperture
76
and is brought into registry with the spout aperture
76
when the support structure
12
is in its erect disposition. The periphery of the inner panel halves
62
a
,
62
b
is generally defined by an extension of the edge margin
50
a
,
50
b
, respectively, side margins
92
a
,
92
b
, side margins
94
a
,
94
b
, and end margins
96
a
,
96
b
, respectively. The two tabs
64
a
and
64
b
of the first end support section
20
are positioned generally between the front outer panel
60
and the two front inner panels
62
a
,
62
b
. The tabs
64
a
,
64
b
are generally trapezoidal in shape being defined by four sides. The four sides of the tabs
64
a
,
64
b
are defined by fold lines
40
a
,
40
b
, side margins
98
a
,
98
b
, side margins l
00
a
,
100
b
, and end margin
102
a
,
102
b
, respectively. It should be noted that side margins
100
a
and l
00
b
lie substantially coincident with side margins
68
a
,
68
b
of the front outer panel
60
and are preferably formed by making a single cut separating tabs
64
a
,
64
b
from hexagonal panel
66
.
The third component of the support section
12
is the second end support section
22
. Second end support section
22
of the support structure
12
is preferably formed of seven individual subcomponents. The seven individual subcomponents are bottom flap
104
, ears
106
a
,
106
b
, locking tabs
108
a
,
108
b
, and top flaps ll
0
a
,
110
b.
The bottom flap
104
is formed integral with the bottom side section
26
along fold line
36
b
. The bottom flap
104
has two projections
112
a
,
112
b
. The projections
112
a
,
112
b
generally flank a locking cutout
114
. The locking cutout
114
is defined in part by lower margin
116
.
The ears
106
a
,
106
b
are generally triangular in shape and are formed integral with the first side sections
28
a
,
28
b
, respectively, along the fold lines
42
a
,
42
b
, respectively.
The locking tabs
108
a
,
108
b
are disposed generally outboard of the locking ears
106
a
,
106
b
. The locking tabs
108
a
,
108
b
are formed integral with second side sections
30
a
,
30
b
, respectively, along the fold lines
48
a
,
48
b
, respectively. Each of the locking tabs
108
a
,
108
b
has a tab projection
118
a
,
118
b
, respectively. As will be seen, the tab projections
118
a
,
118
b
play a key role in locking the second end support section
22
in the erect configuration.
The top flaps ll
0
a
,
110
b
are formed integral with the overlapping top side sections
32
a
,
32
b
, respectively, along fold lines
54
a
,
54
b
, respectively.
The final major component of the blank
16
of the support structure
12
is the handle
24
. The handle
24
is formed integral with the overlapping top side section
32
b
along the fold line
51
.
The handle
24
has two handle halves
120
a
,
120
b
that are generally mirror images of each other. The handle
24
functions as a support device when grasped by a human hand, as depicted in FIG.
1
. The handle halves
120
a
,
120
b
are joined along the fold line
121
. Each of the handle halves
120
a
,
120
b
has a finger cutout
122
a
,
122
b
, respectively. Additionally, handle half
120
a
includes a cutout insert
124
disposed within the finger cutout
122
a
. The cutout insert
124
is formed integral with the handle half
120
a
along fold line
126
. Cutout insert
124
is additionally defined by marginal cut
128
extending from the ends of the fold line
126
around the periphery of the finger cutout
122
a
and the cutout insert
124
.
The blank
16
of the support structure
12
may be cut, stacked, and shipped substantially as depicted in FIG.
3
. Preferably, the blank
16
is prefolded as depicted in
FIGS. 4 and 5
. The preferred folding action is depicted as arrows
1
and
2
in FIG.
4
. The overlapping top side section
32
b
disposed on the overlapping top side section
32
a
and adhered thereto by glue or other means of bonding along glue line
130
. The glue line
130
is brought into registry with strip
131
on the underside of top side section
32
a
, front inner panel
62
a
and top flap
110
a
. Strip
131
is depicted in phantom in FIG.
3
.
To erect the support structure
12
of the disposable container
10
as depicted in
FIGS. 4 and 5
, pressure may be applied inwardly on the fold lines
38
a
and
38
b
. It should be noted that in the folded configuration of
FIGS. 4 and 5
, the fold lines
38
a
,
38
b
form the side margin of the folded blank
16
. Such pressure causes the center support section
18
to form a generally hexagonal shape in cross section as depicted in
FIGS. 1 and 2
. The first end support section
20
and the second end support section
22
may then be put in place to afford an element of rigidity to the now hexagonal center support section
18
.
Commencing with the second end support section
22
(as depicted in FIG.
2
), in a preferred order, the top flap
110
a
,
110
b
is folded downward through an arc of approximately 90 degrees. It should be noted that due to the gluing along glue line
130
, the top flaps
110
a
,
110
b
are held together as a unitary structure.
The next step is to fold the two ears
106
a
,
106
b
inward along fold lines
42
a
,
42
b
. The ears
106
a
,
106
b
are rotated through an arc of approximately 90 degrees to lie in substantially the same plane as the top flap
110
a
,
110
b.
The next step is to fold the bottom flap
104
upward through an arc of approximately 90 degrees such that it partially overlies the top flaps
110
a
,
110
b
in a parallel relationship thereto.
Finally, the locking tabs
108
a
,
108
b
are rotated inward along fold lines
48
a
,
48
b
, respectively. Such rotation through an arc of approximately 90 degrees provides that a portion of the respective locking tabs
108
a
,
108
b
overlies the projections
112
a
,
112
b
of the bottom flap
104
. The tab projections
118
a
,
118
b
are then tucked in behind the lower margin
116
of the locking cutout
114
of the bottom flap
104
to create an interlocking relationship between the locking tabs
108
a
,
108
b
and the bottom flap
104
. This interlocking relationship locks the second end support section
22
in place providing a measure of rigidity to both the second end support section
22
and the center support section
18
of the blank
16
.
Turning to the first end support section
20
(as depicted in FIG.
1
), erection of the first end support section
20
is accomplished first by rotating the inner panel halves
62
a
,
62
b
downward through an arc of substantially 90 degrees along the fold line
52
a
,
52
b
. It should be noted that inner panel half
62
b
overlies a portion of inner panel
62
a
and is affixed thereto along the previously noted glue line
130
. In such disposition, the cutouts
90
a
,
90
b
act cooperatively to define an aperture having substantially the same shape as the spout aperture
76
. In such disposition, the end margins
96
a
,
96
b
are substantially parallel to and proximate the fold line
36
a
. The tabs
64
a
,
64
b
may then be folded inward by rotating the tab
64
a
,
64
b
through a substantially 90 degree arc about the respective fold lines
40
a
,
40
b.
The front outer panel
60
is then rotated into place by folding the front outer panel
60
upward through an arc of substantially 90 degrees about the fold line
36
a
. Prior to reaching the full upward travel of the front outer panel
60
, the tabs
72
a
,
76
b
are folded inward along fold lines
70
a
,
70
b
such that the tabs
72
a
,
72
b
frictionally engage the inner surface of the second side sections
30
a
,
30
b
. The fold lines
70
a
,
70
b
are then parallel to and proximate the end margins
46
a
,
46
b
of the second side sections
30
a
,
30
b
, respectively. The disposition of the front outer panel
60
with respect to the front inner panel
62
a
,
62
b
is such that the spout aperture
76
is in registry with the aperture defined by cutouts
90
a
,
90
b
. It should be noted that preferably the length dimension of the top side sections
32
a
,
32
b
(taken along fold lines
44
a
,
44
b
) is greater than the length dimension of bottom side section
26
(taken along fold lines
34
a
,
34
b
). The first end support section
20
then slants rearward from the fold line
71
to the fold line
36
a
and is therefore not parallel with second end support section
22
.
At this point, the handle
24
is placed into its erect disposition. This is accomplished by rotating the handle
24
through an arc of approximately 90 degrees along the fold line
51
. The handle half
120
b
is then rotated downward along fold line
121
through an arc of substantially 180 degrees to lie parallel with handle
120
. At this point the finger cutouts
122
a
,
122
b
are in registry. The cutout insert
124
is then rotated through an arc of substantially 180 degrees such that the cutout insert
124
passes through the finger cutout
122
b
and lies along side the surface of the handle half
120
b
. In this way, the cutout insert
124
tends to lock the handle halves
120
a
,
120
b
together.
Finally, the tongue
78
is folded rearward along fold line
71
to a point where the slit
84
engages the handle
24
, thereby assisting in locking the handle halves
120
a
,
120
b
together. The upper portion
80
of the tongue
78
is then bent rearward about the fold line
83
to a position substantially overlying the front portion of the handle
24
. In this disposition, the upper
80
and the lower portion
82
of the tongue
78
substantially shield the hand of a user that is grasping the handle
24
from hot liquid vapors.
In a preferred embodiment, the container
10
includes a liquid bladder
14
. The liquid bladder
14
of the present invention is depicted in
FIGS. 6 and 6
a
. Bladder
14
includes a liquid receptacle
142
. In a preferred embodiment, the liquid receptacle
142
is formed of a clear plastic material that is designed to retain and hold liquids having a temperature of up to 250 degrees F. The liquid receptacle
142
is bonded to a semi-rigid neck
144
. The neck
144
preferably has a circular cross section having a diameter that is slightly less than the diameter of the spout aperture
76
. The neck
144
terminates in a threaded mouth
146
. The threaded mouth
146
has a diameter that is greater than the diameter of the spout aperture
76
. A threaded cap
148
is provided to sealingly engage the threads of the threaded mouth
146
.
In an alternative embodiment of the bladder
14
, depicted in
FIG. 6
a
, the threaded cap
148
has a preferably integrally formed spigot
150
. The spigot is provided with a valve handle
152
for selectively opening and closing a valve (not shown) disposed within the spigot
150
.
In operation, after erection of the support structure
12
of the disposable container
10
, the liquid receptacle
142
of the bladder
14
is inserted through the spout aperture
76
. The neck
44
is engaged within the spout
76
. When the support structure
12
is supported on its second end support section
22
, the liquid receptacle
142
depends from the neck
144
and is supported by the periphery of the threaded mouth
146
(the mouth
146
opening generally upward). In this disposition, the threaded cap
148
may be removed from the threaded mouth
146
and liquid may be poured into the liquid receptacle
142
through the neck
144
.
After the liquid receptacle
142
has been substantially filled with liquid, the threaded cap
148
can be sealingly engaged with the threaded mouth
146
. The support structure
12
of the disposable container
10
may be then turned to any other disposition without fear of discharge of liquid from the bladder
14
.
In the alternate embodiment in which the threaded cap contains a threaded spigot
150
, the disposable container
10
may be supported on its bottom side section
26
proximate the edge of a supporting structure such that the spigot
150
projects over the edge of the supporting structure. A cup or other liquid receptacle may be then placed beneath the threaded spigot
150
. Actuation of the valve handle
152
to open the valve (not shown) will then result in the discharge of liquid from the liquid receptacle
142
.
It should be noted that the support structure
12
of the disposable container
10
has a plurality of uses. One such use is as a biodegradable semi-permanent birdhouse. For such use, the support structure
12
is preferably formed of a weather resistant fiberboard or plastic material. In use, the disposable container
10
is placed in a location to attract nesting birds. At the end of the nesting season, when an ordinary birdhouse must be cleaned out, the disposable container
10
is simply removed and disposed of with the accumulated nesting material inside. For such use, the cutouts
122

,
122
b
in the handle
24
are preferably a circular aperture through which a cord may be passed to suspend the container
10
from a tree branch or the like.
Those skilled in the art will recognize that there are numerous variations and modifications of this invention which are encompassed by its scope. Accordingly, the foregoing description should be considered illustrative of the invention and not deemed to limit its scope.
