The present invention relates to cardboard containers and, more particularly, to cardboard containers utilized on conventional pallets.
Numerous corrugated containers have been proposed over the years for confining and protecting heavy or bulky palletized loads. Wooden pallets are in widespread use in industrial or warehouse environments where they are stacked upon one another until use, and thereafter forcibly manipulated and moved about by powerful fork-lift trucks. During transit, these heavily laden pallets are routinely subjected to mechanical stresses and shocks as they are aggressively and sometimes carelessly moved about during typical loading and unloading operations. A variety of heavy duty, corrugated boxes have been designed strictly for pallet use. Many of these fold together and have a plurality of locking straps or flaps that interconnect with portions of the pallet. Most have a base that engages the pallet with an upright, generally tubular body that is polygonal in shape (octagonal and hexagonal configurations are the most common).
Many of the prior art large-capacity pallet boxes must be inverted before unfolding. Either the box must be handled by two workers, or one worker must push it against a wall or similar stationary object to force it to deploy. Typically, six to eight flaps must be manually aligned and interfitted with two or more major flaps on the bottom locking the device together. Once the main bottom flaps are locked, the box is turned over for use. Some boxes of this description are so flimsy that the mere act of flipping them over forces the box apart, necessitating re-assembly prior to loading. Pallet boxes are used in various food industries and may be filled with a thousand or more pounds of meat product such as chicken, beef, or pork.
Because of these heavy loads, the prior art pallet containers are also susceptible to bulging on all sides. The bulging often prevents the most economical packing of pallets and transport of the containers, which results in higher shipping costs. In some cases, the bulging can cause collapse of the container and result in spillage of the contents of the containers.
It would therefore be desirable to develop a pallet container that is durable, not susceptible to bulging, and can be easily deployed from a flat state by a single person without the need of special tools or equipment.
The pallet container of the present invention has eight side walls, a bottom piece, two leg flaps that are used to automatically deploy the container from a flat, collapsed position, and a series of inside folds and outside folds. The pallet container is constructed from one or more blanks made of cardboard. The blanks used to make the pallet container may have different configurations. The pallet container has an open and a closed position and can be converted from one position to the other by a single person without the need of special tools or equipment.
These and other features, objects and advantages of the present invention will become better understood from a consideration of the following detailed description of the preferred embodiments and appended claims in conjunction with the drawings as described following:
With reference to
As described herein, the pallet container 10 can be constructed from blanks having different configurations.
In the first preferred embodiment, as shown in
The first row 38 is joined to the second row 40 along score line 78. The second row 40 of blank 100 is comprised of a glue flap 60, an inside fold 62, a first leg flap 34, an inside fold 64, an outside fold 66, a first bottom flap 30, an outside fold 68, an inside fold 70, a second leg flap 36, an inside fold 72, an outside fold 74, a second bottom flap 32, and an outside fold 76.
The glue flap 60 is joined to the inside fold 62 along score line 42. First leg flap 34 is joined to inside fold 62 along score line 80 on one side and joined to inside fold 64 along score line 82 on the other side. Inside fold 64 is joined to outside fold 66 along score line 44. First bottom flap 30 abuts, but is not joined to, the outside fold 66 on one side and the outside fold 68 on the other side. The outside fold 68 is joined to the inside fold 70 along score line 50. The second leg flap 36 is joined to inside fold 70 along score line 84 on one side and to inside fold 72 along score line 86 on the other side. Inside fold 72 is joined to outside fold 74 along score line 52. Second bottom flap 32 abuts, but is not joined to, the outside fold 74 on one side and the outside fold 76 on the other side. The inside folds 62, 64, 70, 72 are triangular-shaped, preferably in the shape of a right triangle.
The first bottom flap 30 and second bottom flap 32 are preferably in the shape of pentagon. The top side of the flaps 30, 32 is along score line 78. The bottom side (or free side) of the flaps 30, 32 is parallel to the top side. Joined to the two parallel left and right sides of the first bottom flap 30 via score lines 88 are inside flaps 90. Joined to the bottom side of the flap 30 via score line 92 is glue flap 94. Joined to the two parallel sides of the second bottom flap 32 via score lines 96 are inside flaps 98.
As shown in
The bottom piece 28 of the container is formed by joining bottom flaps 30, 32 via glue flap 94. The glue flap 94 of the first bottom flap 30 is preferably glued to the exterior surface of second bottom flap 32. As shown in
The deployment process of converting the container 10 from a flat position (as shown in
The second step of the deployment process is the bottom closing process. With the container 10 in the upright position as shown in
To convert the container 10 back from the open position to the closed position, first wall 12 and fifth wall 20 are pulled outward and away from one another. This causes the container 10 to collapse along score line 118 and score line 120. The bottom piece 28 also folds inward along score line 92. The deployment and collapsing process can easily be performed by a single person.
In addition to being utilized in the deployment and collapsing processes, score lines 118, 120 provide an advantage over prior art containers by preventing the risk of bulging on all sides of the container 10. By being susceptible to bulging along score lines 118, 120, bulging at the third wall 16 and/or seventh wall 20 is therefore prevented. Maintaining the integrity of third wall 16 and seventh 20 is essential to ensure the most economical packing and transport of the multiple pallets with pallet containers.
In the second preferred embodiment, as shown in
The inside flaps 98 joined to the second bottom flap 32 are also notched, thus creating notches 206 between the inside flaps 98 and the second bottom flap 32. The bottom side of second bottom flap 32 is also double notched, thus creating notches 208.
As shown in
Once the bottom piece 28 is formed, the inside flaps 90, 98 are bent upward along score lines 88, 96 and abut first wall 12 and fifth wall 18 in the interior of the container 10. One notch 204 and one notch 206 abut one another in the interior of the container and form slots 212. Once the free ends of first leg flap 34 and second leg flap 36 are received through slots 210 in the bottom piece 28, the free ends are folded parallel to the interior surface of the bottom piece 28 and are received and secured by slots 212.

To construct the pallet container 10 from the blank 800, the eight walls are folded inward along the score lines 42, 44, 46, 48, 50, 52, 54, 56 of the first row 38. Glue flap 58, which is joined to first wall 12, is attached to eighth wall 26 to form the octagon opening 122 of the container 10. Glue flap 58 is preferably glued to the exterior surface of the eighth wall. Glue flap 60 of the second row 40 of the blank 100 is similarly attached to the outside fold 76. When glue flaps 58, 60 are attached to the eighth wall 26, score line 42 is aligned with side edge of the eighth wall 26.
As shown in
In the version of this embodiment comprising score line 118 and score line 120, the first step of the deployment of the container 10 constructed from blank 800 is the same as previously described. However, in the absence of score line 118 and score line 120, the configuration of the container 10 constructed from blank 800 in the flat position is different from the previously described embodiments. Specifically, the container 10 is folded along score line 44 and score line 52 when in the flat position, instead of score lines 118, 120.
In the top opening step of the deployment process of the container, the user pushes score line 44 and score line 52 towards each other. This action transitions the container 10 into the open position. An opening 122 in the top end of the container 10 is created by the eight joined walls 12, 14, 16, 18, 20, 22, 24, 26.
The second step of the deployment process is the bottom closing process. Once the top of the container 10 has been opened, the container 10 preferably is turned upside down to secure the bottom piece 28 of the container 10 by interlocking the first bottom flap 802 and the second bottom flap 808. As explained above, the flaps 802, 808 are interlocked by hooking locking tab 810 into notch 816 and hooking locking tab 814 into notch 812. This causes locking tab 810 to rest on the top surface of second bottom flap 808 and locking tab 814 to rest on the top surface of first bottom flap 802.
Once the bottom piece 28 is assembled, pressure is exerted on the first leg flap 34 and the second leg flap 36. The pressure can be applied manually when the container 10 is upside down or by rocking the container 10 back-and-forth on first leg flap 34 and second leg flap 36 when the container 12 is in the upright position. This pressure causes the leg flaps 34, 36 fold under the bottom piece of the container 10 along score line 78. During the folding process of first leg flap 34, outside fold 76 (connected to glue flap 60) is forced to fold on top of first leg flap 34 along score lines 78, 42, and 80. Thus, inside fold 62 is folded between outside fold 76 and first leg flap 34. Similarly, outside fold 66 is forced to fold on top of first leg flap 34 along score lines 78, 44, and 82. Thus, inside fold 64 is folded between outside fold 66 and the first leg flap 34. During the folding process of second leg flap 36, outside fold 68 is forced to fold on top of second leg flap 36 along score lines 78, 50, and 84. Thus, inside fold 70 is folded between outside fold 68 and second leg flap 36. Similarly, outside fold 74 is forced to fold on top of second leg flap 36 along score lines 78, 52, and 86. Thus, inside fold 72 is folded between outside fold 74 and second leg flap 36. In application, the weight of the load inside the container 10 holds the first leg flap 34 and the second leg flap 36 parallel with bottom piece 28, and thus allows the flaps 34, 36 to serve as reinforcement to the bottom piece 28 of the container.

The free end of flap 808 consists of a notch 816 which creates a locking tab 814. The surface of the first bottom flap 802 also has an opening 906, preferably in the shape of an oval, shaped to receive the free end of first leg flap 902. The surface of the second bottom also has an opening 908, preferably in the shape of an oval, shaped to receive the free end of second leg flap 904.
To construct the pallet container 10 from the blank 900, the eight walls are folded inward along the score lines 42, 44, 46, 48, 50, 52, 54, 56 of the first row 38. Glue flap 58, which is joined to first wall 12, is attached to eighth wall 26 to form the octagon opening 122 of the container 10. Glue flap 58 is preferably glued to the exterior surface of the eighth wall. Glue flap 60 of the second row 40 of the blank 100 is similarly attached to the outside fold 76. When glue flaps 58, 60 are attached to the eighth wall 26, score line 42 is aligned with side edge of the eighth wall 26.
The bottom piece 28 of the container is formed by interlocking the first bottom flap 802 and the second bottom flap 808. The flaps 802, 808 are interlocked by hooking locking tab 810 into notch 816 and hooking locking tab 814 into notch 812. This causes locking tab 810 to rest on the top surface of second bottom flap 808 and locking tab 814 to rest on the top surface of first bottom flap 802.
As shown in
With the absence of score line 118 and score line 120, the configuration of the container 10 constructed from blank 900 in the flat position is different from the first seven previously described embodiments. Specifically, the container 10 is folded along score line 44 and score line 52 when in the flat position.
In the top opening step of the deployment process of the container, the user pushes score line 44 and score line 52 towards each other. This action transitions the container 10 into the open position. An opening 122 in the top end of the container 10 is created by the eight joined walls 12, 14, 16, 18, 20, 22, 24, 26.
The second step of the deployment process is the bottom closing process. Once the top of the container 10 has been opened, the container 10 preferably is turned upside down to secure the bottom piece 28 of the container 10 by interlocking the first bottom flap 802 and the second bottom flap 808. As explained above, the flaps 802, 808 are interlocked by hooking locking tab 810 into notch 816 and hooking locking tab 814 into notch 812. This causes locking tab 810 to rest on the top surface of second bottom flap 808 and locking tab 814 to rest on the top surface of first bottom flap 802. To further secure the bottom piece of the container 10, the free end portion of first leg flap 1002 is received through hole 1006 in first bottom flap 802 and the free end portion of second leg flap 1004 is received through hole 1008 in second bottom flap 808. Once the free ends of the leg flaps 1002, 1004 are received by the holes 1006, 1008, the free ends are folded parallel to the interior surface of the bottom piece 28 to lock them into place.
Once the bottom piece 28 is assembled, pressure is exerted on the first leg flap 34 and the second leg flap 36. The pressure can be applied manually when the container 10 is upside down or by rocking the container 10 back-and-forth on first leg flap 34 and second leg flap 36 when the container 12 is in the upright position. This pressure causes the leg flaps 34, 36 fold under the bottom piece of the container 10 along score line 78. During the folding process of first leg flap 34, outside fold 76 (connected to glue flap 60) is forced to fold on top of first leg flap 34 along score lines 78, 42, and 80. Thus, inside fold 62 is folded between outside fold 76 and first leg flap 34. Similarly, outside fold 66 is forced to fold on top of first leg flap 34 along score lines 78, 44, and 82. Thus, inside fold 64 is folded between outside fold 66 and the first leg flap 34. During the folding process of second leg flap 36, outside fold 68 is forced to fold on top of second leg flap 36 along score lines 78, 50, and 84. Thus, inside fold 70 is folded between outside fold 68 and second leg flap 36. Similarly, outside fold 74 is forced to fold on top of second leg flap 36 along score lines 78, 52, and 86. Thus, inside fold 72 is folded between outside fold 74 and second leg flap 36. In application, the weight of the load inside the container 10 holds the first leg flap 34 and the second leg flap 36 parallel with bottom piece 28, and thus allows the flaps 34, 36 to serve as reinforcement to the bottom piece 28 of the container.

First leg flap 34 is joined to inside fold 62 along score line 80 on one side and joined to inside fold 64 along score line 82 on the other side. Inside fold 64 is joined to outside fold 66 along score line 44. First bottom flap 802 abuts, but is not joined to, the outside fold 66 on one side and the outside fold 68 on the other side. The outside fold 68 is joined to the inside fold 70 along score line 50. The second leg flap 36 is joined to inside fold 70 along score line 84 on one side and to inside fold 72 along score line 86 on the other side. Inside fold 72 is joined to outside fold 74 along score line 52. Second bottom flap 808 abuts, but is not joined to, the outside fold 74 on one side and the outside fold 76 on the other side. Inside folds 62, 64, 70, 72 are triangular-shaped, preferably in the shape of a right triangle.
The top sides of first bottom flap 802 and second bottom flap 808 are along score line 78. The bottom side (free end) of the flap 802 consists of a notch 812 which creates a locking tab 810. The free end of flap 808 consists of a notch 816 which creates a locking tab 814. Attached to one side of flap 802 along score line 1042 is a locking piece 1038. Similarly, attached to one side of flap 808 along score line 1044 is a locking piece 1040.
To construct the pallet container 10 from the blank 1000, the eight walls are folded inward along the score lines 42, 44, 46, 48, 50, 52, 54, 56 of the first row 38. Glue flap 58, which is joined to first wall 12, is attached to eighth wall 26 to form the octagon opening 122 of the container 10. Glue flap 58 is preferably glued to the exterior surface of the eighth wall. Glue flap 60 of the second row 40 of the blank 100 is similarly attached to the outside fold 76. When glue flaps 58, 60 are attached to the eighth wall 26, score line 42 is aligned with side edge of the eighth wall 26.
The bottom piece 28 of the container is formed by interlocking the first bottom flap 802 and the second bottom flap 808. The flaps 802, 808 are interlocked by hooking locking tab 810 into notch 816 and hooking locking tab 814 into notch 812. This causes locking tab 810 to rest on the top surface of second bottom flap 808 and locking tab 814 to rest on the top surface of first bottom flap 802.
In the top opening step of the deployment process of the container, the user pushes score line 44 and score line 52 towards each other. This action transitions the container 10 into the open position. An opening 122 in the top end of the container 10 is created by the eight joined walls 12, 14, 16, 18, 20, 22, 24, 26.
The second step of the deployment process is the bottom closing process. Once the top of the container 10 has been opened, the container 10 preferably is turned upside down to secure the bottom piece 28 of the container 10 by interlocking the first bottom flap 802 and the second bottom flap 808. As explained above, the flaps 802, 808 are interlocked by hooking locking tab 810 into notch 816 and hooking locking tab 814 into notch 812. This causes locking tab 810 to rest on the top surface of second bottom flap 808 and locking tab 814 to rest on the top surface of first bottom flap 802. As shown in
Locking piece 1038 is then folded downward along score line 1042 thereby locking first bottom flap 802 to first wall 12. Similarly, locking piece 1040 is received by flap 1036. Locking piece 1040 is then folded downward along score line 1044 thereby locking second bottom flap 808 to fifth wall 20.
Once the bottom piece 28 is assembled, pressure is exerted on the first leg flap 34 and the second leg flap 36. The pressure can be applied manually when the container 10 is upside down or by rocking the container 10 back-and-forth on first leg flap 34 and second leg flap 36 when the container 12 is in the upright position. This pressure causes the leg flaps 34, 36 fold under the bottom piece of the container 10 along score line 78. During the folding process of first leg flap 34, outside fold 76 (connected to glue flap 60) is forced to fold on top of first leg flap 34 along score lines 78, 42, and 80. Thus, inside fold 62 is folded between outside fold 76 and first leg flap 34. Similarly, outside fold 66 is forced to fold on top of first leg flap 34 along score lines 78, 44, and 82. Thus, inside fold 64 is folded between outside fold 66 and the first leg flap 34. During the folding process of second leg flap 36, outside fold 68 is forced to fold on top of second leg flap 36 along score lines 78, 50, and 84. Thus, inside fold 70 is folded between outside fold 68 and second leg flap 36. Similarly, outside fold 74 is forced to fold on top of second leg flap 36 along score lines 78, 52, and 86. Thus, inside fold 72 is folded between outside fold 74 and second leg flap 36. In application, the weight of the load inside the container 10 holds the first leg flap 34 and the second leg flap 36 parallel with bottom piece 28, and thus allows the flaps 34, 36 to serve as reinforcement to the bottom piece 28 of the container.
As shown in

The second row of blank 1102 is comprised of glue flap 706, an inside fold 70, a second leg flap 1106, an inside fold 72, an outside fold 74, a second bottom flap 1114, and an outside fold 76.
The glue flap 60 of blank 1100 is joined to the inside fold 62 along score line 42. First leg flap 1104 is joined to inside fold 62 along score line 80 on one side and joined to inside fold 64 along score line 82 on the other side. Inside fold 64 is joined to outside fold 66 along score line 44. First bottom flap 1112 abuts, but is not joined to, the outside fold 66 on one side and the outside fold 68 on the other side. The glue flap 706 of blank 1102 is joined to the inside fold 70 along score line 50. The second leg flap 1106 is joined to inside fold 70 along score line 84 on one side and to inside fold 72 along score line 86 on the other side. Inside fold 72 is joined to outside fold 74 along score line 52. Second bottom flap 1114 abuts, but is not joined to, the outside fold 74 on one side and the outside fold 76 on the other side. The inside folds 62, 64, 70, 72 are triangular-shaped, preferably in the shape of a right triangle.
The first bottom flap 1112 and second bottom flap 1114 are substantially in the shape of pentagon. The top side of flap 1112 is along double score lines 78, 1124. The top side of flap 1114 is along double score lines 716, 1126. The bottom side (free end) of the flaps 1112, 1114 is parallel to the top side. Joined to the bottom side of flap 1112 is glue flap 1132. The flap 1112 is separated from glue flap 1132 by two score lines 1128, 1130. The double score lines are used to prevent the corrugated material from splitting or fracturing when the blanks are folded. The top corners of the first bottom flap 1112 include rounded sections 1134, 1136 positioned between the double score lines 78, 1124. Similarly, the top corners of the second bottom flap 1114 include rounded sections 1138, 1140 positioned between the double score lines 716, 1126. These rounded sections prevent tearing of the bottom flaps 1112, 1114 when the blanks 1100, 1102 are folded along score lines 46, 48, 54, 56.
The free end of flap 1104 includes two hooked portions 1108 positioned opposite one another. The free end of flap 1106 includes two hooked portions 1110 positioned opposite one another. The surface of the first bottom flap 1112 has two openings 1116 shaped to receive one hooked end 1108 of flap 1104 and one hooked end 1110 of flap 1106. The surface of the second bottom flap 1114 also has two openings 1118 shaped to receive one hooked end 1108 of flap 1104 and one hooked end 1110 of flap 1106. The bottom flaps 1112, 1114 each also include an oval opening 1120, 1122. The openings serve as hand holes for use while assembling the container 10 formed from blanks 1100, 1102.
To construct the pallet container 10 from blanks 1100, 1102, glue flap 1132 is attached to second bottom flap 1114. To construct the top piece of the container 10, glue flap 58 of blank 1100 is attached to eighth wall 26 of blank 1102. Glue flap 60 is also attached to outside fold 76. In addition, glue flap 704 of blank 1102 is attached to fourth wall 18. Glue flap 706 is also attached to outside fold 68. Once the eight walls are folded inward along the score lines 42, 44, 46, 48, 50, 52, 54, 56, the octagon 122 opening of the container 10 is formed.
The deployment process of the container 10 constructed from blanks 1100, 1102 is the same as previously described. Once the container 10 is deployed, to further secure the bottom piece 28 of the container 10, one hooked end 1108 of first leg flap 1104 is received and secured through opening 1116 in first bottom flap 1112 and the other hooked end 1108 is received and secured through opening 1118 in second bottom flap 1114. One hooked end 1110 of the second leg flap 1106 is received and secured through the second opening 1116 in the first bottom flap 1112 and the other hooked end 1110 is received and secured through the second opening 1118 in second bottom flap 1114. Using the hooked ends 1108, 1110 to further secure the bottom piece 28 of the container 10 is optional. In other words, the container 10 is fully functional without locking the hooked ends 1108, 1110. The hand holes 1120, 1122 may assist the assembler in locking the hooked ends 1108, 1110 in the receiving slots 1116, 1118. To collapse the container 10 formed from blanks 1100, 1102, the hooked ends 1108, 1110 must be removed from the openings 1116, 1118 and the container 10 may be collapsed as previously described.
