1. Field of the Invention
The present invention is directed generally to collapsible containers and more particularly to collapsible containers for storing and transporting industrial goods and food products including liquids and solid/liquid mixtures.
2. Description of the Related Art
Presently, many liquid and solid/liquid mixtures are stored and/or transported in wooden boxes or containers lined with one or more sheets of plastic. The wooden containers include a plurality of uprighted and interconnected side panels extending upwardly from a base and defining an open interior of the container. The open interior may be covered by a removable lid disposed along the top portions of the panels. The lid is secured to the top portions of the panels by metal banding or strapping wrapped around the outside of the container. The uprighted panels may also be held in place by metal banding or strapping.
These prior art containers have several drawbacks. For example, they are bulky and heavy. Because the wood is porous, the contents of the container may rot or become infested or otherwise contaminated. Assembly and disassembly of these containers requires tools such as banding tools and cutters to remove bands. The banding is hazardous and creates a risk of injury caused by wood splinters and the sudden release of energy stored in the metal banding. Further, repeated assembly and disassembly damages the wood and after repeated assembly/disassembly cycles, renders the wood unsuitable for container construction.
Therefore, a need exists for a collapsible container for storing liquid and solid/liquid mixtures. A further need exists for a collapsible container that may be assembled and disassembled manually without the use of tools. A need also exists for a method of securing a lid to the panels of the container without the use of metal banding. Further, a need exists for shipping and/or storage containers constructed from a non-porous material that prevents rot, infestation, and contamination.
As used herein, the term “goods” refers to materials and items that may be placed into a container for storage and/or transport. These materials and items include without limitation personal property, articles of trade, wares, merchandise, agricultural products, processed food products, bulk solid items, liquids, and the like. In particular embodiments, the term “goods” may refer to liquid/solid suspensions including food products
As used herein, the term “composite material” refers to a material constructed using two or more component materials combined to produce a material with properties considered superior to the properties of either component material alone. Composite materials may include a fiber material embedded in a matrix material. For example, composite materials may include a synergistic mixture of glass fibers and a polymer, such as polypropylene, polyethylene terephthalate (PET), and polyvinyl chloride (PVC). When glass fibers are properly combined with the polymer, the resultant composite material may have substantial strength and stiffness relative to its weight. Composite materials characteristically perform over a broad temperature range and may be used to reduce the complexity of many structures.
The present invention is directed toward a collapsible container 10. Referring to

The use of composite materials to construct the panels 20A and 20B may produce panels that are lightweight when compared to the prior art wooden panels used to construct containers. The challenges of using the composite material to construct the container 10 led to the invention of novel edge joining components and structures. Aspects of the present invention relate to how the panels 20A and 20B are joined to a base 30 as well as how adjoining panels 20A and 20B are connected together to form corners 44A, 44B, 44C, and 44D of the container 10. As will be discussed in detail below, the panels 20A of the first panel type differ from the panels 20B of the second panel type in the manner in which the panels 20A of the first panel type are coupled to the base 30.
Referring to
Each of the panels 20A and 20B is coupled by its bottom portion 90 to the base 30. The base 30 has a perimeter portion 130 defining a central or center portion 132. The bottom portion 90 of each of the uprighted panels 20 is arranged around the perimeter portion 130 of the base 30 in an alternating fashion with each of the panels 20A of the first panel type being flanked by a pair of panels 20B of the second panel type. Each of the panels 20 has an inside facing face 170 defining a portion of the interior 12 of the container 10 and an outward facing face 180 opposing the inside facing face 170. Each of the panels 20 may have a thickness defined between the outward facing face 180 and the inside facing face 170 of about 0.5 inches to about 2 inches. In particular embodiments, the thickness of the panels 20 may be about 0.75 inches to about one inch.
In the embodiment depicted in
Each of the panels 20A and 20B is coupled to the pair of panels flanking it by an edge joining assembly 140 (see
The edge joining assembly 140 may include a first elongated joining member 150 and a second elongated joining member 160. The first elongated joining member 150 longitudinally engages the second elongated joining member 160 and locks therewith to prevent the lateral disengagement of the first elongated joining member 150 from the second elongated joining member 160.
In the embodiment depicted in
The second side portion 120 of the back panel 60 is adjacent to the second side portion 120 of the second side panel 80. Either the first elongated joining member 150 or second elongated joining member 160 is coupled to the second side portion 120 of the back panel 60. The other of the first elongated joining member 150 and second elongated joining member 160 is coupled to the second side portion 120 of the second side panel 80. The longitudinal locking engagement of the first elongated joining member 150 and the second elongated joining member 160 couples the back panel 60 to the second side panel 80 and prevents their lateral disengagement. The longitudinally locked together first elongated joining member 150 and the second elongated joining member 160 may form a second corner 44B between the back panel 60 and the second side panel 80. The second corner 44B may have a second angle “θ2.” The second angle “θ2” is preferably about 90°. However, embodiments in which the angle “θ2” is greater or less than about 90° are also within the scope of the present invention.
The second side portion 120 of the front panel 50 is adjacent to the second side portion 120 of the second side panel 80. Either the first elongated joining member 150 or second elongated joining member 160 is coupled to the second side portion 120 of the front panel 50. The other of the first elongated joining member 150 and second elongated joining member 160 is coupled to the second side portion 120 of the second side panel 80. The longitudinal locking engagement of the first elongated joining member 150 and the second elongated joining member 160 couples the front panel 50 to the second side panel 80 and prevents their lateral disengagement. The longitudinally locked together first elongated joining member 150 and the second elongated joining member 160 may form a third corner 44C between the front panel 50 and the second side panel 80. The third corner 44C may have a third angle “θ3.” The third angle “θ3” is preferably about 90°. However, embodiments in which the angle “θ3” is greater or less than about 90° are also within the scope of the present invention.
The first side portion 110 of the back panel 60 is adjacent to the first side portion 110 of the second side panel 80. Either the first elongated joining member 150 or second elongated joining member 160 is coupled to the first side portion 110 of the back panel 60. The other of the first elongated joining member 150 and second elongated joining member 160 is coupled to the first side portion 110 of the second side panel 80. The longitudinal locking engagement of the first elongated joining member 150 and the second elongated joining member 160 couples the back panel 60 to the second side panel 80 and prevents their lateral disengagement. The longitudinally locked together first elongated joining member 150 and the second elongated joining member 160 may form a fourth corner 44D between the back panel 60 and the second side panel 80. The fourth corner 44D may have a fourth angle “θ4.” The fourth angle “θ4” is preferably about 90°. However, embodiments in which the angle “θ4” is greater or less than about 90° are also within the scope of the present invention.
As is also appreciated by those of ordinary skill, while the container 10 has been described as having a total of four panels, two each of panels 20A and 20B, it is apparent to those of ordinary skill that a container (not shown) having more than four panels 20A and 20B may be constructed by joining a greater number of panels 20A and 20B together pair-wise using the edge joining assemblies 140 and such embodiments are within the scope of the present invention.

Each of the inside sidewall 208 and the outside sidewall 209 may have a width “W1.” The relieved portion 220 may have a width “W2” that is approximately equal to the width “W1” of the inside sidewall 208 and the outside sidewall 209. The relieved portion 224 may have a width “W3” that is approximately equal to the width “W1” of the inside sidewall 208 and the outside sidewall 209. The relieved portion 220 may be formed in the first side portion 110 by removing surface material from the inside facing face 170 and/or the outside facing face 180 along a portion of the first side portion 110 using any conventional method(s) known in the art such as milling, planing, sanding, sawing, and the like Alternatively, the relieved portion 220 may be molded or otherwise formed at the desired size without the need for removing material. In particular embodiments, the first side portion 110 may be compressed to form the relieved portion 220. The relieved portion 224 may be similarly formed in the second side portion 120 using any method suitable for forming the relieved portion 220 in the first side portion 110.
The locking portion 210 includes an outwardly projecting, longitudinally extending key portion 212. The elongated key portion 212 has a top end portion 213 formed in the top end portion 152 of the first elongated joining member 150 and a bottom end portion 214 formed in the bottom end portion 154 of the first elongated joining member 150. In the embodiment depicted in
While the embodiment of the key portion 212 depicted in the drawings has a generally tapered cross-sectional shape that is narrower near mating surface 218 and widens the farther the key portion 212 projects therefrom, those of ordinary skill in the art appreciate that alternate cross-sectional shapes, including a generally T-shaped or knob-shaped cross-sectional shape (see a key portion 1212 depicted in
An angle “α” may be defined between the mating surface 218 of the angled stop wall 216 and the inside sidewall 208. In various embodiments, the angle “α” is about 450. In alternate embodiments, the angle “α” is about 90°. In further embodiments, the angle “α” is about 180°. The invention is not limited by the magnitude of the angle “α” and alternate magnitudes of the angle “α” are within the scope of the invention.
The second elongated joining member 160 may include a connector 226 integrally formed with or coupled to a locking portion 240. The connector 226 is configured to be coupled to either the first side portion 110 or the second side portion 120 of one of the panels 20.

The locking portion 240 of the second elongated joining member 160 may include an angled stop wall 250. In various embodiments, the channel 246 of the keyway portion 242 extends inwardly into the locking portion 240 in a direction substantially orthogonal to the angled stop wall 250.
While the embodiment of the channel 246 of the keyway portion 242 depicted in the drawings has a generally tapered cross-sectional shape that is wider near mating surface 252 and narrows as the keyway portion 242 extends inwardly into the locking portion 240, those of ordinary skill in the art appreciate that alternate cross-sectional shapes, including a generally T-shaped or knob-shaped cross-sectional shape (see a keyway portion 1242 depicted in
An angle “β” may be defined between the mating surface 252 of the angled stop wall 250 and the inside sidewall 228 of the connector 226. In various embodiments, the angle “β” is about 45°. In alternate embodiments, theangle “β” is about 90°. In further embodiments, the angle “β” is about 180°. The invention is not limited by the magnitude of the angle “β” and alternate magnitudes of the angle “β” are within the scope of the invention.
The angled stop wall 216 of the locking portion 210 of the first elongated joining member 150 bears against the angled stop wall 250 of the locking portion 240 of the second elongated joining member 160 when the key portion 212 of the first elongated joining member 150 is received inside the keyway portion 242 of the second elongated joining member 160. In this manner, the angles “α” and “β” of the angled stop walls 216 and 250 determine the angles “θ1,” “θ2,” “θ3,” and “θ4,” defined between the adjacent panels 20 at the corners 44A, 44B, 44C, and 44D, respectively.
With reference to
As is apparent to those of ordinary skill, the connector portion 221 may be configured to receive preferentially only the relieved portion 201.

The connector portion 225 may be formed in the second side portion 120′ using any method suitable for forming connector portion 221 in the first side portion 110′. The relieved portion 201 may be formed in the connector 200′ using any method suitable for forming the relieved portion 220 in the first side portion 110. Alternatively, the relieved portion 201 may be formed in the connector 200′ in the same manner the key portion 212 is formed in the locking portion 210 of the first elongated joining member 150. The relieved portion 203 may be formed in the connector 226′ using any method suitable for forming the relieved portion 201 in the connector 200′.
As is apparent to those of ordinary skill, one of the first and second elongated joining members 150 and 160 may include the connector 200 while the other of the first and second elongated joining members 150 and 160 includes the connector 200′. In various embodiments, the relieved portion 220 may be formed in the first side portion 110 permitting it to be coupled to one of the first elongated joining member 150 and the second elongated joining member 160 but not the other. As is apparent to those of ordinary skill, in such embodiments, because the first side portion 110 includes the relieved portion 220, the second side portion 120 includes the connector portion 225. In alternate embodiments, the first side portion 100 includes the connector portion 202 and the second side portion 120 includes the relieved portion 220.
With reference to
The connector 1200 includes a connector portion 1202. The connector portion 1202 includes a longitudinally extending inside sidewall 1208 spaced apart from a longitudinally extending spaced apart outside sidewall 1209 and defining an interior 1204 therebetween. The inside sidewall 1208 includes a contoured surface 1205 facing into the interior 1204. The contoured surface 1205 includes an inwardly projecting portion 1235 that projects into the interior 1204 between the sidewalls 1208 and 1209, thereby narrowing a portion 1236 of the interior 1204 adjacent the inwardly projecting portion 1235.
The outside sidewall 1209 includes a contoured surface 1207 facing the interior 1204. The contoured surface 1207 includes an inwardly projecting portion 1211 that projects into the interior 1204 between the sidewalls 1208 and 1209, thereby further narrowing the portion 1236 of the interior 1204 adjacent the inwardly projecting portion 1211. In the embodiment depicted in
The inside sidewall 1208 has an inside distal end 1237 and the outside sidewall 1209 has an outside distal end 1238. The inside distal end 1237 includes a tapered sidewall 1241 extending distally and outwardly from the inside facing contoured surface 1205, widening the interior 1204 between the distal ends 1237 and 1238. The outside distal end 1238 includes a tapered sidewall 1245 extending distally and outwardly from the inside facing contoured surface 1207, widening the interior 1204 between the distal ends 1237 and 1238. An open-ended tapered portion 1243 of the interior 1204 may be defined between the tapered sidewalls 1241 and 1245.
The second elongated joining member 1160 includes a connector 1226 integrally formed or coupled to a locking portion 1240. The connector 1226 may be substantially identical to the connector 1200 of the first elongated joining member 1150. The locking portion 1240 may be substantially similar to the locking portion 240 depicted in
In embodiments of the container 10 that include the first elongated joining member 1150 and second elongated joining member 1160, the relieved portion 220 of the first side portion 110 and the relieved portion 224 of the second side portion 120 may be shaped substantially similarly to the interior 1204 of the connector 1200 of the first elongated joining member 1150. For example, the inside facing face 170 along the relieved portion 220 of the first side portion 110 may include a recessed portion (not shown) configured to receive the inwardly projecting portion 1235 of the inside sidewall 1208 and the outside facing face 180 along the relieved portion 220 of the first side portion 110 may include a recessed portion (not shown) configured to receive the inwardly projecting portion 1211 of the outside sidewall 1209. In this manner, the inwardly projecting portions 1235 and 1211 may be seated inside the recessed portions to resist disengagement of the first elongated joining member 1150 or the second elongated joining member 1160 from the first side portion 110. The recessed portions may formed by compressing a portion of the first side portion 110. Alternatively, the recessed portions may be formed using any conventional method(s) known in the art such as milling, planing, sanding, sawing, and the like. In further embodiments, the recessed portions may be molded or otherwise formed at the desired size without the need for removing material.
In various embodiments, the relieved portion 224 of the second side portion 120 may be shaped in a substantially identical manner allowing the inwardly projecting portions 1235 and 1211 to be seated inside the recessed portions and thereby resist disengagement of the first elongated joining member 1150 or the second elongated joining member 1160 from the second side portion 120.
The connector portion 1202 may be coupled or affixed to the relieved portion 220 or the relieved portion 224 in any manner suitable for coupling the connector portion 202 to the relieved portion 220 of the first side portion 110 or the relieved portion 224 of the second side portion 120. As is apparent to those of ordinary skill, the various corners 44A, 44B, 44C, and 44D may be constructed using any of the of the embodiments of the edge joining assembly 140 disclosed herein. Further, different embodiments of the edge joining assembly 140 may be used to construct the various corners 44A, 44B, 44C, and 44D of a single embodiment of the container 10.

In the embodiment depicted in
In particular embodiments, a single groove 410A or 410B is formed along each of the sides 403 of the perimeter portion 404. In the embodiment depicted in the figures, each of the grooves 410A of the first groove type are open ended, extending along the entire side 403 in which the groove 410A is formed to create a first open end 412 and a second open end 413 opposite the first open end 412. Each of the grooves 410B of the second groove type extend along only a portion of the side 403 in which the groove 410B is formed and terminate short of the groove 410A. In such embodiments, a portion 414 of the top surface 400 of the bottom panel 320 separates each groove 410A from the adjacent grooves 410B flanking it. In alternate embodiments, each of the grooves 410A of the first groove type extends only a portion of the length of the side 403 in which the groove 410A is formed. In some embodiments, each of the grooves 410B of the second groove type extend along the entire side 403 in which the groove 410B is formed.
In an alternate embodiment of the bottom panel 320 depicted in
The grooves 410A or 410A′, or in the alternative, the groove shape shown as grooves 410A″ in
As mentioned above, the panels 20A of the first panel type differ from the panels 20B of the second panel type in the manner in which the panels 20A of the first panel type are coupled to the base 30. Specifically, the bottom portion 90 of the panels 20A of the first panel type differs from the bottom portion 90 of the panels 20B of the second panel type. The grooves 410A and grooves 410A″ of the first groove type are configured to receive the bottom portion 90 of the panels 20A of the first panel type. The grooves 410B of the second groove type are configured to receive the bottom portion 90 of the panels 20B of the second panel type.
Referring to
The grooves 410A of the first groove type include an undercut portion 460A sized and shaped to receive the toe portion 450A of the bottom portion 90 of the panels 20A. The undercut portion 460A extends inwardly from the groove 410A and toward the center portion 132 of the base 30. The undercut portion 460A extends the entire length of the groove 410A at a location juxtaposed with the toe portion 450A when the bottom portion 90 is received within the groove 410A. In the embodiment depicted in the figures, the toe portion 450A traverses the entire length of the relieved portion 440A. However, in alternate embodiments, the toe portion 450A and corresponding undercut portion 460A may traverse only a portion of the length of the relieved portion 440A and groove 410A, respectively.
Referring to
Engagement between the toe portion 450 and the undercut portion 460A prevents the panel 20A from pivoting outwardly away from the interior 42 of the container 10. However, a predetermined amount of inwardly directed rotational force (i.e., force applied in a direction opposite the direction indicated by arrow “B1”) could pivot the panel 20A inside the groove 410A inwardly toward the interior 42 of the container 10, and thereby extract the toe portion 450A from the undercut portion 460A, and dislodge the relieved portion 440A from the groove 410A. In this manner, each of the panels 20A may be disassembled from the base 30.
An alternate embodiment of the panels 20A of the first panel type and the grooves 410A′ of the first groove type is illustrated in

In the embodiment depicted in
Referring to
Like each of the grooves 410A, which are open ended, extending along the entire side 403 in which the groove 410A is formed to create a first open end 412 and a second open end 413 opposite the first open end 412, the grooves 410A′ may be open ended. In alternate embodiments, the relieved portion 440A′ may be installed in the groove 410A′ by placing the panel 20A in an upright orientation and sliding the relieved portion 440A′ into one of the open ends of the groove (and thereby the toe portion 450A′ into the undercut portion 460A′) adjacent to one of the sides 403 (see
In the embodiment depicted in
Each of the panels 20A is connected to the base 30 by an elongated anchor member 1430A coupled to a corresponding panel anchor strip 1406A disposed on the top surface 1400 of the bottom panel 1320. The anchor member 1430A includes a connector 1432A integrally formed with or coupled to an anchor portion 1434A. The relieved portion 92 is received inside the connector 1432A of the anchor member 1430A. The connector 1432A may be substantially identical to the connector 200 of the first elongated joining member 150. In the embodiment depicted in the figures, the connector 1432A includes a longitudinally extending sleeve or connector portion 1433A having an interior 1435 defined between a pair of sidewalls 1437 and 1439. The interior 1435 is sized and shaped to receive the relieved portion 92 therein. Each of the sidewalls 1437 and 1439 may extend laterally and upwardly along the relieved portion 92.
The connector 1432A may be affixed to the relieved portion 92 in any manner suitable for affixing the connector 200 of the first elongated joining member 150 to the first or second side portions 110 and 120 of one of the panels 20A and 20B.
In the embodiment depicted in the figures, the connector 1432A is offset laterally from the anchor portion 1434A creating an overhanging portion 447A. The overhanging portion 447A may be adjacent to the outside facing face 180 of the panel 20A. An underside 449A of the overhanging portion 447A may bear against the top surface 1408A of the panel anchor strips 1406A when the anchor member 1430A is coupled thereto.
The anchor portion 1434A may be substantially identical to the relieved portion 440A described above. Alternatively, the anchor portion 1434A may include a toe portion 4450A″ that extends laterally therefrom away from the center portion 132 of the base 30 when assembled therewith.
The toe portion 4450A″ may have a bead-like cross-sectional shape. As is apparent to those of ordinary skill in the art, while the cross-sectional shape of the toe portion 4450A″ differs from the cross-sectional shape of toe portion 450A depicted in the figures, the toe portion 4450A″ is equivalent to the toe portion 450A and functions in a substantially identical manner thereto. Further, those of ordinary skill will readily recognize alternate cross-sectional shapes suitable for use with the toe portion 450A and the toe portion 4450A″, such as square, rectangular, oval, trapezoidal, arbitrary, and the like, and such embodiments are within the scope of the present invention.
In various embodiments, the anchor portion 1434A includes a downwardly extending projection 451. In embodiments wherein the connector 1432A is offset laterally from the anchor portion 1434A, the downwardly extending projection 451 may be offset laterally from the bottom portion 90 of the panel 20A.
The groove 410A″ formed in the panel anchor strip 1406A may include an undercut portion 4460A″ configured to receive the toe portion 4450A″ in substantially the same manner the undercut portion 460A (see
Referring to
The groove 410A″ may include a bottom surface 453 having an interior longitudinally extending groove 455 formed therein. The interior groove 455 is sized and shaped to receive the downwardly extending projection 451 when the anchor portion 1434A is received inside the groove 410A″. Engagement between the downwardly extending projection 451 and the interior groove 455 may help maintain the panel 20A in an upright orientation. Engagement between the overhanging portion 447A and the top surface 1400 of the bottom panel 1320 may help prevent the panel 20A from rotating outwardly within the groove 410A″.
Referring to
The grooves 410B of the second groove type include an undercut portion 460B sized and shaped to receive the toe portion 450B of the bottom portion 90 of the panels 20B. The undercut portion 460B extends laterally outwardly from the groove 410B and away from the center portion 132 of the base 30. The undercut portion 460B extends along the groove 410B with the toe portion 450B received therein when the bottom portion 90 is received within the groove 410B. In the embodiment depicted in the figures, the toe portion 450B extends along the entire length of the relieved portion 440B. However, in alternate embodiments, the toe portion 450B and corresponding undercut portion 460B may extends along only a portion of the length of the relieved portion 440B and groove 410B, respectively.
A method of assembling the panel 20B into the groove 410B will now be described. First, each of the panels 20B of the container 10 is uprighted, with the bottom surface 454B of the bottom portion 90 of each panel 20B placed adjacent to an opening 456B of the corresponding groove 410B with the inside facing face 170 facing the interior 42 of the container 10. The relieved portion 440B of each of the panels 20B is then directed downwardly, in the direction indicated by arrow “C” to snap fit into the groove 410B. The panel 20B may be directed downwardly by pressure applied by the user to the top portion 100 or elsewhere on the panel 20A. A predetermined amount of outwardly directed force or pressure applied to the inside facing face 170 of the panel 20B forces or directs the toe portion 450B into the undercut portion 460B of the groove 410B.
The goods 14 inside the interior 42 of the container 10 may bear against the inside facing face 170, exerting a force thereupon, and maintain the toe portion 450B inside the undercut portion 460B of the groove 410B. Engagement between the toe portion 450B and the undercut portion 460B prevents the panel 20B from pivoting inwardly toward the interior 42 of the container 10. If the predetermined amount of outwardly directed force or pressure applied to the inside facing face 170 of the panel 20B is removed or reduced below a predetermined threshold value, the toe portion 450B may disengage with the undercut portion 460B, allowing the relieved portion 4440B to be removed from the groove 410B, by an upwardly directed force, i.e., a force in a direction opposite the direction indicated by arrow “C”. In this manner, the panels 20B may be disassembled from the base 30. The predetermined amount of outwardly directed force or pressure applied to the inside facing face 170 of the panel 20B by the goods 14 may be removed or reduced by moving all or a portion of the goods 14 contained in the container 10.

Each of the panels 20B is connected to the base 30 by an elongated anchor member 1430B coupled to a corresponding panel anchor strip 1406B disposed on the top surface 1400 of the bottom panel 1320. The anchor member 1430B includes a connector 1432B integrally formed with or coupled to an anchor portion 1434B. The relieved portion 92 is received inside a connector 1432B of an anchor member 1430B. The connector 1432B may be substantially identical to the connector 1432A of the anchor member 1430A and therefore will not be described in detail.
The anchor portion 1434B may be substantially identical to the relieved portion 440B (see
In the embodiment depicted in the figures, the connector 1432B is offset laterally from the anchor portion 1434B creating an overhanging portion 447B. The overhanging portion 447B may be adjacent to the outside facing face 180 of the panel 20B. An underside 449B of the overhanging portion 447B may bear against the top surface 1408B of the panel anchor strips 1406B when the anchor member 1430B is coupled thereto. Engagement between the underside 449B of the overhanging portion 447B and the top surface 1408B of the panel anchor strips 1406B help prevent the anchor portion 1434B from rotating inside the groove 410B and thereby disengaging the toe portion 450A from the undercut portion 460B and potentially disassembling the panel 20B from the base 30.
In particular embodiments, the first elongated member 150 and second elongated member 160 are fixedly installed on the panels 20A and 20B before the panels 20A and 20B are coupled to the base 30. In such embodiments, the panels 20A must be installed before the panels 20B. Otherwise, the first elongated member(s) 150 and/or second elongated member(s) 160 installed on the panels 20B will interfere with leaning the panels 20A inwardly during insertion into the grooves 410A. After a pair of panels 20A flanking a selected panel 20B are installed, the selected panel 20B may be installed therebetween by inserting the key portion 212 of the first elongated joining members 150 of the edge joining assemblies 140 adjacent to the first and second side portions 110 and 120 of the selected panel 20B into the keyway portion 242 of the second elongated joining members 160 of the edge joining assemblies 140 adjacent to the first and second side portions 110 and 120 of the selected panel 20B, and sliding the key portions 212 downwardly within the keyway portions 242 until the relieved portion 440B of the selected panel 20B is received inside the corresponding groove 410B. When the key portion 212 of the first elongated joining members 150 is received inside the keyway portion 242 of the second elongated joining member 160, the mating surface 218 may be slid longitudinally along the mating surface 252 to allow the key portion 212 to slide within the keyway portion 242.
Referring to
The container 10 may be disassembled by eliminating or reducing the outwardly directed force or pressure applied to the inside facing face 170 of the panel 20B below the predetermined threshold value and upwardly lifting the selected panel 20B thereby sliding the key portions 212 upwardly within the keyway portions 242 until the relieved portion 440B of the selected panel 20B is removed from the corresponding groove 410B and the key portions 212 of the edge joining assemblies 140 adjacent to the first and second side portions 110 and 120 of the selected panel 20B exit the keyway portions 242 of the edge joining assemblies 140 adjacent to the first and second side portions 110 and 120 of the selected panel 20B. Then, each of the panels 20A may be leaned inwardly and lifted out of their corresponding grooves 410A. In this manner, the container 10 is collapsed or disassembled without the use of hand tools.
While assembly and disassembly of the container 10 has been described with reference to the first elongated joining members 150 and the second elongated joining members 160, it is appreciated by those of ordinary skill in the art that the first elongated joining members 1150 is substantially similar to the first elongated joining member 150 and the second elongated joining member 1160 is substantially similar to the second elongated joining member 160, and embodiments of the container 10 incorporating the first and second elongated joining members 1150 and 1160 may be assembled and disassembled in a substantially similar manner. Similarly, the first elongated joining members 150′ is substantially similar to the first elongated joining member 150 and the second elongated joining member 160′ is substantially similar to the second elongated joining member 160, and embodiments of the container 10 incorporating the first and second elongated joining members 150′ and 160′ may be assembled and disassembled in a substantially similar manner.

An alternate embodiment of the container 10 will now be described. Referring now to
The container 10′ differs from the container 10 with respect to the structure of the corners 44A, 44B, 44C, and 44D. Specifically, each of the corners 44A, 44B, 44C, and 44D is not formed by the edge joining assembly 140. Instead, each of the corners 44A, 44B, 44C, and 44D is formed by a bent portion 600, 610, 620, and 630, respectively, of the panels 20A′. Each of the bent portions 600, 610, 620, and 630 extends substantially vertically between the bottom portion 90 and the top portion 100 of one of the panels 20A′. The bent portions 600, 610, 620, and 630 may be formed in the panels 20A′ using any method known in the art.
With reference to
While in the embodiment depicted in the figures the bent portions 600, 610, 620, and 630 are provided in the panels 20A′ of the first panel type, i.e., the first and second side panels 70′ and 80′, those of ordinary skill in the art appreciate that the bent portions 600, 610, 620, and 630 may be provided in the panels 20B′ of the second panel type, i.e., the front and back panels 50′ and 60′, and such embodiments are within the scope of the present invention. Further, only the first side portion 110 of the panels 20A′ and the second side portion 120 of the panels 20B′ may include a bent portion. Alternatively, only the first side portion 110 of the panels 20B′ and the second side portion 120 of the panels 20A′ may include a bent portion.

In this embodiment, if the first elongated joining member 150 is rotated 180°, the angle “α′” is defined between the mating surface 218 and the outside sidewall 209 (which would have been the inside sidewall 208 had the first elongated joining member 150 not been rotated 180°), otherwise, the angle “α′” is defined between the mating surface 218 and the inside sidewall 208. If the second elongated joining member 150 is rotated 180°, the angle “β′” is defined between the mating surface 252 and the outside sidewall 230 (which would have been the inside sidewall 228 had the second elongated joining member 160 not been rotated 180°), otherwise, the angle “β′” is defined between the mating surface 252 and the inside sidewall 228. In other words, the sidewall used to define the angles “α′” and “β′” does not change with the orientation of the first elongated joining member 150 and the second elongated joining member 160, respectively.
In the embodiment depicted in the figures, the angles “α′” and “β′”. total about 90°. In alternate embodiments, each of the angles “α′” and “β′” may be about 90°. Therefore, when the key portion 212 of the first elongated joining member 150 is inserted into the keyway portion 242 of the second elongated joining member 160, and the mating surface 218 is adjacent to and sealed with the mating surface 252, instead of constructing a corner, the edge joining assembly 140 constructs a linear section 700A, 700B, 700C, or 700D of container 10′.
In the embodiment depicted in
The first elongated joining member 150 of the edge joining assembly 140 nearest the corner 44B is not rotated and the second elongated joining member 160 of the same edge joining assembly 140 is rotated 180°. When the key portion 212 of the first elongated joining member 150 is inserted into the keyway portion 242 of the second elongated joining member 160, the edge joining assembly 140 constructs the linear section 700B of the container 10′.
The first elongated joining member 150 of the edge joining assembly 140 nearest the corner 44C is not rotated and the second elongated joining member 160 of the same edge joining assembly 140 is rotated 180°. When the key portion 212 of the first elongated joining member 150 is inserted into the keyway portion 242 of the second elongated joining member 160, the edge joining assembly 140 constructs the linear section 700C of the container 10′.
The first elongated joining member 150 of the edge joining assembly 140 nearest the corner 44D is rotated 180° and he second elongated joining member 160 of the same edge joining assembly 140 is not rotated. When the key portion 212 of the first elongated joining member 150 is inserted into the keyway portion 242 of the second elongated joining member 160, the edge joining assembly 140 constructs the linear section 700D of the container 10′.
While particular arrangements of the first elongated joining member 150 and second elongated joining member 160 used to construct the linear sections 700A, 700B, 700C, and 700D of container 10′ have been described, those of ordinary skill in the art appreciate that alternate configurations of the first elongated joining member 150 and second elongated joining member 160 may be used to construct a linear section of the container 10′ and such embodiments are within the scope of the present invention.

A portion 680A of the first side panel 70A′ located between the bent portion 600 and the first end portion 110 may be adjacent to and/or rest upon the portion 414′ of the top surface 400 nearest the corner 44A. A portion 680B of the first side panel 70A′ located between the bent portion 610 and the second end portion 120 may be adjacent to and/or rest upon the portion 414′ of the top surface 400 nearest the corner 44B. A portion 680C of the second side panel 80A′ located between the bent portion 620 and the second end portion 120 may be adjacent to and/or rest upon the portion 414′ of the top surface 400 nearest the corner 44C.

The container 10′ may be assembled in the same manner the container 10 is assembled. The bottom portion 90 of the panels 20A′ may be substantially identical to the bottom portion 90 of the panels 20A allowing the panels 20A′ to be assembled with the base 30′ in the same manner the panels 20A are assembled with the base 30. The bottom portion 90 of the panels 20B′ may be substantially identical to the bottom portion 90 of the panels 20B. However, because the groove 410B′ is longitudinally shorter than the groove 410B, the bottom portion 90 of the panels 20B′ may be correspondingly shorter than the bottom portion 90 of the panel 20B. The panels 20B′ may be assembled with the base 30′ by inserting the bottom portion 90 into the groove 410B′ in the same manner the panels 20B are assembled with the base 30. The container 10′ may be disassembled in the same manner the container 10 is disassembled.

The foregoing described embodiments depict different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely exemplary, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected,” or “operably coupled,” to each other to achieve the desired functionality.
While particular embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that, based upon the teachings herein, changes and modifications may be made without departing from this invention and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of this invention. Furthermore, it is to be understood that the invention is solely defined by the appended claims. It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations).
Accordingly, the invention is not limited except as by the appended claims.
