Abstract
A container for holding and facilitating dispensing of a substance. The container has a body with a peripheral wall defining a storage space for a substance and an opening in communication with the storage space to facilitate introduction of a substance into the storage space and dispensing of a substance from the storage space. The body has a top and bottom, a top wall, a bottom wall, and oppositely facing wall surfaces on the peripheral wall between the top and bottom of the body. There is a fold structure on the body that causes a part of the body to reposition in a predetermined manner relative to another part of the body as an incident of the captive force being exerted on the oppositely facing wall surfaces. The fold structure includes a fold line that extends substantially fully between the top and bottom of the body and over a substantial portion of the bottom wall.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to containers of the type used to hold non-rigid, pourable materials and, more particularly, to a container that can be reconfigured to facilitate the discharge of the materials therefrom.
2. Background Art
A myriad of different non-rigid, pourable substances are sold in containers for dispensing by an end user. Exemplary of such substances are toothpaste, consumable substances such as ketchup, honey, beverages, and the like, adhesives, lubricants, etc. A typical container for these substances will have a generally cylindrical body with a discharge opening over which a removable cap is placed.
Some such substances are held in containers having a substantially fixed configuration. For example, beverages are commonly sold in glass or metal containers. These containers must be inverted to allow gravitational flow of the substance through the discharge opening. While this type of container is suitable for most consumable beverages, there are problems associated with these containers when they are used to dispense more viscous substances.
For example, ketchup is offered by various manufacturers in both glass bottles and plastic “squeeze bottles”. Most people have experienced problems in discharging ketchup from a glass bottle. Patrons in restaurants can frequently be seen pounding on the bottom of the inverted bottle or hitting the neck thereof to initiate discharge and ultimately choosing the unsanitary route and placing an eating utensil through the discharge opening to start the flow of the ketchup.
Aside from this problem is the problem of exhausting substantially the entirety of the substance from the glass container. When the user stores the glass containers with ketchup or salad dressing therein, the remaining amounts settle to the bottom of the container. Discharge involves inverting the bottle to cause the remaining substance to flow, often slowly, by gravity up to and out of the discharge opening. This is aggravated by the fact that the substance over long periods of time may lose moisture and solidify at the bottom of the container. This problem is often addressed by putting the cap over the container and storing the container on a flat surface, such as a countertop, in an inverted position until all of the substance migrates to the vicinity of the discharge opening. Alternatively, the consumer will avoid this inconvenience and discard the container with a significant amount of the usable substance still therein. While this may increase sales to a manufacturer, it is inefficient and often frustrating to a consumer.
Squeeze bottles obviate the above problems to a certain extent. A typical squeeze bottle will be made from a plastic material that is shape-retentive but deformable under a predetermined pressure to reduce the storage volume, increase the internal pressure, and cause an expulsion of the substance under pressure through the discharge opening. This type of container typically has a bottom wall with a large enough footprint to stably support the container in an upright, storage position. The bottom wall of the container is, by reason of its configuration, relatively rigid. The most conveniently squeezable portion of the container is the mid-portion thereof. In a full container, pressure at the mid-portion results in flow division, with the material above the mid-portion being forced toward the discharge opening and the substance below the mid-portion being urged toward the bottom of the container. As the substance is exhausted and the substance level is below the mid-portion, the user is required to reposition the substance above the mid-portion before squeezing. This may be accomplished by inverting the container for some time or by sharply thrusting the container so that the momentum of the substance causes it to reposition toward the upper region of the container. This is obviously inconvenient and often requires strength not possessed by a consumer. Thus, the squeezable container is likewise difficult to fully empty, potentially leading to significant amounts of waste.
A further problem with a squeezable container is that the material may not have the resilience to re-assume an undeformed state after it is squeezed. This may be aggravated over time as the material loses its initial resilience. Further, the user may have a tendency to exert an excessive squeezing pressure on the container, particularly when the quantity of the substance is relatively small. In a worst case, this could lead to a rupture of the container, most commonly at a molding seam.
It is also known to use non-shape-retentive containers to dispense substances. For example, toothpaste is commonly placed in a tube that can be rolled from the bottom end to force the paste up toward the discharge opening where it can be easily squeezed out. While this is an effective way of facilitating substance discharge, ofttimes this makes product identity difficult. An important feature of most every container is the ability to present to the supplier and/or manufacturer an opportunity to place their identity on the product which remains through its useful life. Used toothpaste tubes commonly become a wrinkled, unappealing mass. At some point, the advertising material on the container becomes completely obliterated. Product identification for purposes of reordering may be made difficult or impossible.
While the obscuring of the product or supplier/manufacturer identity may be nothing more than a marketing problem in the aftermarket, sometimes these containers include directions or warnings that are important for safe use thereof. The user may be deprived of this information, which could result in an improper and, in a worst case, dangerous use of a product.
Generally, both of the squeezable and deformable containers, described above, may be difficult or inconvenient to use for someone with limited strength or a handicap, such as arthritis.
Another problem with squeezable containers is that often the quality of the substance discharge is compromised. For example, a substance such as ketchup may separate, with the solid particles in the solution migrating downwardly, leaving primarily liquid at the top. By squeezing the mid-portion, initially the liquid will be discharged. While this problem could be alleviated by shaking and pre-mixing the substance in the container, this may not be a common practice for the consumer.
Still other substances may be made of multiple components which tend to naturally separate under gravitational force. By squeezing the container at the mid-portion, lighter components are pressed upwardly for discharge while heavier components may be squeezed even further to the bottom of the container.
SUMMARY OF THE INVENTION
In one form of the invention, a container is provided for holding and facilitating dispensing of a substance. The container has a body with a peripheral wall defining a storage space for a substance and an opening in communication with the storage space to facilitate introduction of a substance into the storage space and dispensing of a substance from the storage space. The body has a top and bottom, a top wall, a bottom wall, and oppositely facing wall surfaces on the peripheral wall between the top and bottom of the body. There is a fold structure on the body that causes a part of the body to reposition in a predetermined manner relative to another part of the body as an incident of a captive force being exerted on the oppositely facing wall surfaces. The fold structure includes a fold line that extends substantially fully between the top and bottom of the body and over a substantial portion of the bottom wall.
A cap can be removably connected to the body to selectively block the body opening.
In one form, the peripheral wall has a circumference and the fold line has first and second portions that are spaced from each other around the circumference of the body and extending over the bottom wall substantially fully between the first and second portions.
The fold line may extend over at least a part of the top wall of the body.
The fold structure may be made up of accordion folds having a length extending in a direction between the top and bottom of the body.
In one form, the peripheral wall has an outer surface that has at least one of a) a cylindrical outline, b) an elliptical outline, and 3) an oval outline in cross-section.
The accordion folds may reside within the outline of the peripheral wall or extend outwardly therefrom.
The body may be made from a shape retentive material. The body has an undeformed state and a deformed state in which the body is in with a predetermined captive force applied. The body substantially assumes the undeformed state after the predetermined captive force is removed.
The body may be formed as one piece.
In another form of the invention, a container is provided for holding and facilitating dispensing of a substance. The container has a body with a peripheral wall defining a storage space for a substance and an opening in communication with the storage space to facilitate introduction of a substance into the storage space and dispensing of the substance from the storage space. The body has a top and bottom, a top wall, a bottom wall, a front wall and a rear wall facing oppositely to the front wall. Structure is provided on the body for causing the body to reconfigure in a predetermined manner as an incident of the front and rear walls being moved towards and away from each other. The structure may include a plurality of accordion folds on the bottom wall of the container.
The structure may include non-straight folds that extend around the opening.
The structure may further include accordion folds on the top wall of the body.
The structure may include accordion folds extending between the top and the bottom of the body.
In one form, the peripheral wall has a circumference, with the accordion folds at first and second locations spaced around the circumference of the peripheral wall and each having a length extending between the top and bottom of the container.
The accordion folds on the bottom wall may extend continuously between the according folds at the first and second locations.
In one form, the bottom wall has an area and the accordion folds on the bottom wall extend over substantially the entire area of the bottom wall.
In another form of the invention, a container is provided for holding and facilitating dispensing of a substance. The container has a body with a peripheral wall defining a storage space for a substance and an opening in communication with the storage space to facilitate introduction of a substance into the storage space and dispensing of a substance from the storage space. The body has top and bottom and an outer wall with oppositely facing wall surfaces between the top and bottom of the body. A fold line has a first portion that extends between the top and bottom of the body and causes a part of the body to reposition in a predetermined manner relative to another part of the body as an incident of a captive force being exerted on the oppositely facing wall surfaces. The peripheral wall has a first circumference with the outer wall having a second circumference. The circumference of the outer wall may be substantially greater than the circumference of the peripheral wall.
The folds may extend over each of the top and bottom walls continuously between the first and second locations on the peripheral wall. The body opening may be offset from the folds.

DETAILED DESCRIPTION OF THE DRAWINGS
In FIGS.
1
-
3
, a first form of container, according to the present invention, is shown as
10
. The container
10
has a body
12
with a peripheral wall
14
defining a storage space
16
for a substance and a bottom wall
17
for supporting the container
10
in an upright position on a subjacent support surface. The precise substance that is placed in the container
10
is irrelevant to the invention. The substance is preferably a non-rigid, pourable substance that is conventionally caused to be dispensed from a container, such as toothpaste, edible products such as ketchup and salad dressing, oils, adhesives, caulking, shampoos, creams, gels, and the like. A reduced diameter neck
18
is provided on a top wall
19
of the container
10
and defines an opening
20
in communication with the storage space
16
to facilitate introduction of a substance into the storage space
16
and dispensing of the substance from the storage space
16
. A cap
21
is removably connected to the neck
18
, as through cooperating threads, to selectively block the opening
20
.
The peripheral wall
14
has oppositely facing first and second wall surfaces
22
,
24
extending substantially fully between the top and bottom of the container
10
. The first wall surface
22
is viewable in elevation as seen in FIG.
2
. The second wall surface
24
is viewable by turning the body
12
through 180° around a vertically extending center line (VCL) from the
FIG. 2
position. The wall surface
22
at the front of the container
10
has a substantial area to accommodate written materials or logos shown generically at
26
. The written material may include a description of the contents of the container
10
, cautionary material, directions for use, etc. The wall surface
24
at the rear of the container
10
may bear similar messages or logos, as shown generally at
28
.
Fold structure
30
is provided, with portions
31
,
32
thereof at diametrically opposite locations on the container
10
. The third wall surface is viewable in elevation in
FIG. 1
with the fourth wall surface viewable by turning the body
12
through 180° around the vertically extending center line. A horizontal center line (CL—one shown) for each of the third and fourth wall surfaces is located between the first and second wall surfaces
22
,
24
. The first, second, third and fourth wall surfaces are viewable in succession by rotating the body
12
around the vertically extending center line (VCL). The portions
31
,
32
of the fold structure
30
are the same, with the exemplary fold structure portion
31
being defined by a zigzag pattern of flat wall parts
34
,
36
,
38
,
40
which produce accordion folds. The third and fourth wall surfaces have a width dimension (W). The accordion wall surfaces occupy substantially less than the width dimension for each of the third and fourth wall surfaces.
By exerting a captive force, such as through the application of forces F
1
, F
2
in Opposite directions on the wall surfaces
22
,
24
, the wall parts
42
,
44
defining the wall surfaces
22
,
24
, are caused to reposition in a predetermined manner relative to each other. As the forces F
1
, F
2
are applied, the wall parts
34
,
36
fold against each other about a fold line
46
, with the wall parts
38
,
40
folding against each other in a similar fashion about a fold line
48
. The wall parts
36
,
38
fold relative to each other about a fold line
50
, with the wall parts
34
and
40
folding relative to the wall parts
42
,
44
, respectively, about fold lines
52
,
54
. Through this folding action, the effective volume of the storage space
16
is reduced, thereby causing the substance in the container
10
to be expelled under pressure through the opening
20
.
In this particular embodiment, the fold lines
46
,
48
,
50
,
52
,
54
extend fully from the bottom edge
56
of the container
10
to the neck
18
. The invention contemplates that the fold lines
46
,
48
,
50
,
52
,
54
could extend less than the entire height of the container
10
. Further, the fold lines
46
,
48
,
50
,
52
,
54
extend over the bottom wall
17
fully between the fold structure portions
31
,
32
.
With this arrangement, the curved wall parts
42
,
44
maintain their shape and relative position as the forces F
1
, F
2
are applied thereto. Typically, the forces F
1
, F
2
are applied by grasping the container in the user's hand and using the fingers to draw the container compressibly into the palm to effect expulsion of the substance in the container
10
. Preferably, the body
12
is made in one piece from a plastic or other shape-retentive material that will deform as described above and reassume an undeformed state after the forces F
1
, F
2
are removed.
Accordingly, the surfaces
22
,
24
may remain substantially undeformed through the life of the container
10
. As a result, the message/logos
26
,
28
thereon remain intact as a convenience to the user and for product identity. At the same time, the expulsion of the substance is facilitated by the fold structure
30
,
32
, which also facilitates collapsing of the container to squeeze the contents therefrom.
Another feature of the present invention is the provision of V-shaped recesses
58
,
60
,
62
,
64
, with the recesses
60
,
62
being formed by the fold structure
30
over the bottom wall
17
. Exemplary recess
58
is bounded by wall parts
66
,
68
which meet at a fold line
70
. As the wall surface
24
at the bottom of the container
10
is pressed toward the wall surface
22
, the wall part
66
moves against the wall part
68
. This causes the wall part
24
to collapse inwardly toward the wall part
66
, thereby collapsing the space
72
between the wall parts
44
,
66
and thereby urging the substance upwardly beyond the recess
58
. Accordingly, the recesses
58
,
60
,
62
,
64
serve the dual purposes of a) reducing the volume of the storage space
16
for the contained substance at the bottom of the container
10
and b) facilitating squeezing of the substance from that part of the container
10
at the height of the recesses
58
,
60
,
62
,
64
. Accordingly, the substance at the bottom of the container
12
can be (conveniently squeezed upwardly in the container
10
for proper mixing with the remaining substance and expulsion through the opening
20
. This is the same type of action that is commonly produced by squeezing a tube of toothpaste from the bottom thereof. This arrangement permits a relatively complete exhaustion of the container substance.
To increase the footprint of the container
10
, an optional cap
74
can be provided on the bottom wall
17
of the container
10
.
As shown in phantom in a variation in
FIG. 2
, the container need not be uniformly cylindrical along its entire height. In this case a peripheral wall
14
′ defining the storage space
16
′ can have a circumference less than that of the outer peripheral wall
14
. This produces an exposed display area that is greater than that afforded by the circumference of the peripheral wall
14
′. Purveyors can thus sell a relatively small quantity of substance with a greater display area than would normally be permissible by the peripheral wall
14
′ for better product promotion. In this embodiment, the size of the space
16
′ also decreases from top to bottom.
In another variation, the neck
18
and cap
21
can be offset as shown in phantom lines in FIG.
1
. This allows the fold lines
46
,
48
,
50
,
52
,
54
to extend fully over the top wall
19
, as shown also in phantom lines, so that the neck
18
does not interfere with the collapsing.
In FIGS.
4
-
6
, a modified form of container, according to the present invention, is shown at
80
. The most significant difference between the container
80
and the container
10
, previously described, is that the container
80
has a fold structure
82
with an accordion-type arrangement with six flat wall parts
84
,
86
,
88
,
90
,
92
,
94
as compared to the corresponding five wall parts
34
,
36
,
38
,
40
,
42
on the container
10
. Additionally, recesses
96
at the bottom of the container
80
have a shorter vertical extent than do the recesses
58
,
60
,
62
,
64
in the container
10
.
Another modified form of container, according to the present invention, is shown at
98
in FIGS.
7
-
9
. The container
98
is similar to the container
80
, with the primary difference being that a part of the fold structure at
100
projects outwardly from the cylindrical outline
102
for the outer surface
104
of the peripheral wall
106
. Wall parts
108
,
110
are foldable relative to each other about a fold line
112
. The wall part
108
is foldable relative to a shallower wall part
114
around a fold line
116
. The wall part
110
is foldable relative to a shallower wall part
118
about a fold line
120
.
The surfaces
108
,
110
,
114
,
118
cooperatively define a conveniently grippable portion of the container
98
and also increase the storage capacity for the container
98
over that which the container
98
would have if the same type of fold structure
100
did not project outside of the container outline
102
.
The recesses
122
at the bottom of the container
98
have a vertical extent that is greater than that for the recesses
96
on the container
80
and less than that for the recesses
58
,
60
,
62
,
64
for the container
10
.
A further modified form of container, according to the present invention, is shown at
124
in FIGS.
10
-
12
. The container
124
is similar to the container
98
, with the primary difference being that the fold structure
126
does not project to within the container outline
128
. Whereas the container
98
has two wall parts
108
,
110
that are foldable against each other, the fold structure
126
has a first pair of wall parts
130
,
132
that are foldable towards each other about a fold line
134
and a second pair of wall parts
136
,
138
that are foldable against each other about a fold line
140
. The wall parts
132
,
136
are foldable relative to each other about a fold line
141
. The wall part
130
is foldable relative to a wall part
142
about a fold line
144
, with the wall part
138
being is foldable relative to a wall part
146
about a fold line
148
. With this arrangement, the capacity of the container
124
is increased by an amount equal to the space bounded by the wall parts
130
,
132
,
136
,
138
,
142
,
146
outside of the container outline
128
. Recesses
150
at the bottom of the container
124
have a vertical extent on the order of that for the recesses
96
on the container
80
.
A further modified form of container, according to the present invention is shown at
160
in FIGS.
13
-
15
. The container
160
has a fold structure
162
having features of the fold structures
30
,
82
,
100
,
126
on the containers
10
,
80
,
98
,
124
. The fold structure
162
has shallow and deep wall parts
164
,
166
which are foldable relative to each other about a fold line
168
and shallow and deep wall parts
170
,
172
foldable relative to each other about a fold line
174
. The wall parts
166
,
172
are foldable relative to each other about a fold line
176
. A certain amount of the volume reduction resulting from the projection of the surfaces
164
,
166
,
170
,
172
to within the container outline
178
is compensated for by the projection of the wall parts
166
,
172
outside of the container outline
178
.
In
FIG. 16
, a further modified form of container, according to the present invention, is shown at
180
. The container
180
has first and second fold lines
182
,
184
. The fold line
182
allows one part
186
of a peripheral wall
188
to be folded in a predetermined manner relative to another part
190
of the peripheral wall
188
. In this case, the fold line
182
is defined by scoring which produces a weakening, so that the fold line
182
acts as a hinge. The fold line
182
can extend to a diametrically opposite location on the container
180
.
The fold line
184
has spaced weakening lines
192
which cause a part
194
of the peripheral wall
188
to fold in a predetermined fashion relative to the wall part
190
. The fold line
192
can likewise extend to a diametrically opposite location on the container
180
.
In
FIG. 17
a modified form of container, according to the present invention, is shown at
200
. The container
200
has a substantially flat front wall
202
and rear wall (not shown) to provide a substantial usable area for writing and/or a logo, which may be applied thereto through a label
204
that can be suitably attached, as by an adhesive. The container
200
has fold structure
206
at diametrically opposite sides thereof. In cross-section, the container
200
has either an oval or a square shape.
In
FIG. 18
a further modified form container, according to the present invention, is shown at
210
, and has a generally oval body
212
with fold structure
214
at its sides.
In
FIG. 19
, the invention is incorporated into a drum container
220
. The drum container
220
has fold structure at
222
in the form of accordion folds extending continuously through 360° over a top wall
224
, bottom wall
226
, and peripheral wall

therebetween. A cap
229
is offset from the accordion folds. The drum
220
could be any size ranging from several ounces to conventional 45 or 55 gallon capacity, or even greater. The fold structure
222
may include accordion folds as shown in phantom lines over substantially the entire peripheral wall
228
to facilitate a more compact collapsing of the drum container.
This construction, when used on high volume (1000's of gallons) containers, allows the containers to be collapsed, as for introduction into tight areas, after which the containers can be expanded to full size. This may obviate reconfiguration of an edifice around the container.
A lifting loop
230
can be provided on the top wall
224
on the fold structure
222
. Handles or openings
232
may be located in the raised portions of the accordian folds to facilitate lifting and transportation of the drum container
220
. The handles/openings
232
can be molded directly into the drum container
220
.
A bung opening
234
can be provided on or in between accordion surfaces to mount spigots or other valves.
In
FIG. 20
, a further modified form of container is shown at
240
having a body
242
with a top wall
244
with a neck
246
thereon and an opening
248
through the neck
246
. Fold line structure at
250
extends vertically along the peripheral wall
252
of the body
242
and has a non-straight path that curves around the neck
246
. This allows collapse of the body
242
around the neck
246
without having to offset the neck
246
from the fold line structure
250
, as shown in FIG.
1
. The fold line structure
250
may extend continuously to and over a bottom wall (not shown) to permit a compact collapsing to occur.
In each embodiment, the flexibility at the fold lines can be enhanced by scoring continuously or in the form of serration. Alternatively, a reduced thickness can be provided at the fold lines through the molding process. The fold lines can be extended over substantially the entirety of the peripheral surface of each container to facilitate collapse thereof to a compact state continuously through 360° around the top, bottom and peripheral walls.
While the invention performs well with shape-retentive container materials, the invention contemplates making the containers from any material that is not shape-retentive, such as aluminum or other metal. Non-shape retentive material such as paper, cloth, composites, etc. could also be used. With these materials, reconfiguration is facilitated by the present invention to a permanently collapsed state. Combinations of shape-retentive and non-shape retentive materials are also contemplated. The non-shape retentive materials allow for compact collapsing of the containers as for ecologically effective disposal. Using the shape-retentive materials, this same collapsed state can be maintained, such as with the container
10
, by tightening the cap
21
in place with the container
10
collapsed. The container can then either be disposed of or re-pressurized to allow filling to its expanded capacity for re-use.
By facilitating reconfiguration of containers, the invention makes everyday use of products potentially easier for children, handicapped persons, or persons with arthritis and allows these same persons to potentially relatively easily compact the container for disposal after use.
The invention permits other products, such as caulking, to be discharged without the need for a separate tool, such as a dispensing “gun” as is commonly used with caulking. This is a convenience and results in a cost saving to the consumer.
The expandable nature of the container allows it to be partially collapsed when filled so as to occupy less space. Volatile materials and highly expandable materials are allowed to expand and contract without unduly stressing the container.
The invention has a potentially universal use, such as in aircraft, ships, automobiles, above ground, in-ground, and underwater tanks.
The foregoing disclosure of specific embodiments is intended to be illustrative of the broad concepts comprehended by the invention.
