Abstract
A packaging and stabilizing system and method for creating a pallet of vertically aligned rolls of material. The packaging system includes a plurality of individual interlocking devices that each extend between the cores of a pair of rolls on the pallet. The interlocking devices are installed to create a lattice pattern between the rolls on the pallet such that the rolls are stabilized and prevented from tipping. Each individual roll of the pallet can be removed by first removing the interlocking devices connecting the roll to the remaining rolls in the pallet. Once the interlocking devices are removed, the roll can be removed without compromising the stability of the remaining rolls on the pallet.
Description
- The present application is based on and claims priority to U.S. Provisional Patent Application Serial No. 60/400,653 filed on Aug. 1, 2002.
- The present invention relates to a packaging system for use in packaging vertically-oriented rolls of material. More specifically, the present invention relates to a packaging system for interlocking vertically-oriented rolls of material on a pallet such that the rolls of material can be individually stacked and later removed while the remainder of the rolls on the pallet are stabilized.
- Many types of materials required by industry are supplied in large quantities by rolling the material about a hollow, substantially cylindrical core. Depending on the type of goods, the core may be formed from cardboard, plastic, metal or some other type of material. Alternatively, rolls of material can also be formed without a core. After the material has been wound onto a roll during manufacture, a desired number of individual rolls are packaged together and sent to the consumer.
- When packaging rolled goods for shipment, warehouse handling or storage, it is a conventional practice to stack the individual rolls on a pallet such that the rolls are vertically-oriented relative to their longitudinal axis. In a typical pallet system, the rolls may be packaged in a number of individual rows with each row having a number of rolls. Depending upon the length of the rolls, multiple layers may be stacked onto a single pallet. Typically, once a pallet is formed, packaging material, such as stretch wrap or shrink-wrap and paperboard end protectors, are used to secure the pallet and prevent the rolls from tipping during storage and shipment.
- Presently, a packaging system exists that includes a top cardboard or paperboard template that includes multiple die cut openings positioned to receive a core extension of each roll when the rolls are stacked on a pallet. The template interlocks the individual rolls by utilizing a plastic plug that passes through an opening in the template and into the core extension. When the template is installed on the rolls assembled on a pallet, the template prevents the rolls from tipping. However, this type of packaging system has a significant drawback in that once the template is removed, the individual rolls are no longer interlocked and can tip. Typically, the entire interlocking template must be removed from the top of a pallet of rolls prior to the rolls being unstacked. Additionally, when the rolls are initially stacked at the manufacturer, the template is not positioned on the pallet until the entire pallet has been formed.
- When such a pallet is delivered to a consumer, the consumer removes the outer packaging material, including the top template, and removes the individual rolls of material one at a time. During the unloading of a pallet after the outer packaging material has been removed, it is possible for the rolls to be bumped and fall onto the floor from the pallet. Since some pallets are stacked such that the rolls are between six inches and four feet above the floor, a falling roll of material could be severely damaged upon contact with the floor. The damage to a roll could be so severe that the entire roll would need to be scrapped.
- In addition to the problems identified above, currently available packaging system typically require many separate, individual components to provide an interlock between the plurality of stacked, vertical rolls. The numerous parts required increases the packaging costs of the rolls of material. Further, once the rolls have been unloaded, the numerous packaging materials required to interlock the rolls of vertically aligned material creates a significant amount of scrap material that must be disposed of by the consumer.
- Therefore, a need exists for a packaging system that allows vertical stacked rolls of material to be interlocked with each other to prevent tipping of the individual rolls during either the stacking or unstacking process. Further, a need exists for a packaging system that allows individual rolls from the pallet to be removed while allowing the remaining rolls in the pallet to be stabilized. Further, a need exists for a packaging system that is inexpensive and easy to install.
- The present invention generally relates to a packaging system for stabilizing a plurality of vertically-oriented rolls on a pallet. The packaging system of the present invention allows the rolls to be removed from the pallet individually while maintaining the stability of the remaining rolls on the pallet.
- The packaging system of the present invention includes a plurality of individual interlocking devices that can be configured based on the application such that one size will fill most applications by bending or folding in the appropriate position. Once the interlocking device has been properly sized, the interlocking devices are positioned between a pair of rolls on the pallet. The interlocking devices extend between the open cores of a pair of rolls and interlock a pair of rolls to each other. The interlocking devices are positioned between the rolls on the pallet to create a lattice extending between the roll cores such that the rolls are adequately stabilized.
- During the initial formation of the pallet, an interlocking device is positioned between each roll and another roll on the pallet as each roll is added to the pallet. In this manner, the pallet is stabilized during the entire time it is being constructed, unlike the packaging system of the prior art. Likewise, when the pallet of vertically-oriented rolls is disassembled, the individual interlocking devices are sequentially removed only as individual rolls are removed to allow the pallet to maintain its stabilization while allowing the individual rolls to be removed.

- FIG. 10 is a perspective view of a backing member used with the alternate embodiment of the packaging and stabilizing system of the present invention.
- Referring first to FIG. 1, thereshown is a prior art packaging and stabilizing system10. The prior art packaging system 10 is utilized to stabilize a pallet of closely spaced
rolls 12 for shipping. Each of therolls 12 is vertically-oriented for shipment. - As illustrated in FIG. 1, each of the
rolls 12 is supported at its lower end by abottom template 14 having a series ofdie cut openings 16. Thedie cut openings 16 are each sized to receive a core extension that extends past the lower edge of the film wound upon each of therolls 12. Thebottom template 14, in turn, is supported upon thepallet 18 for shipping. - Once the pallet of
rolls 12 has been assembled onto thebottom template 14, atop template 20 is positioned on the top end of eachroll 12 to secure the rolls in an ordered, packaged condition. As illustrated in FIG. 1, thetop template 20 includes a series ofdie cut openings 22 each sized to receive anupper core extension 23 formed on each of therolls 12. As illustrated in FIG. 2, once thetop template 20 has been positioned as shown, anindividual backing member 24 andend plug 26 are inserted into each of thecore extensions 23 to secure thetop template 20 in the position as shown. In the preferred embodiment of the invention, thebottom template 14, thetop template 20 and thebacking members 24 are all formed from cardboard or paperboard, while theend plug 26 is formed from a plastic material. - Although the packaging system10 shown in FIG. 1 is effective for stabilizing a pallet of vertically-oriented rolls during shipment, significant drawbacks exist during the assembly and disassembly of the pallet. As can be understood in FIG. 1, when a
roll 12 is to be removed from the pallet, all of the individual end plugs 26 andbacking members 24 must first be removed from the cores of the plurality ofrolls 12. Once all of the end plugs 26 andbacking members 24 have been removed, thetop template 20 can be lifted from the pallet and therolls 12 removed individually. - As can be understood in FIG. 1, once the
top template 20 has been removed, the rolls of material are no longer stabilized and are thus subject to tipping. This condition exists both during the initial stacking and subsequent unstacking of the rolls to form a pallet for shipment. Additionally, the packaging system 10 of the prior art includes many individual components, including thetop template 20, the plurality ofindividual backing members 24, and end plugs 26 that must be stored prior to assembly and disposed of once the pallet has been unstacked. - Referring now to FIG. 3, thereshown is a first embodiment of the packaging and stabilizing
system 30 of the present invention. Thepackaging system 30 provides a system for stabilizing a plurality ofindividual rolls 12 loaded onto a pallet while allowing the individual rolls 12 to be removed from the pallet one at a time while simultaneously maintaining stability for the remaining rolls on the pallet. Additionally, thepackaging system 30 of the present invention allows the loaded rolls to be stabilized during the formation of the pallet as each individual roll is added to the pallet. - As illustrated in FIG. 3, each
individual roll 12 includes acore extension 32 that extends above thetop edge surface 34 of the roll. Thecore extension 32 in the preferred embodiment of the invention extends approximately ¼ to one inch above thetop edge surface 34 and defines anopen center 36 that extends along the entire longitudinal length of theroll 12. Alternatively, the core may be flush with thetop edge surface 34. - In accordance with the present invention, the
packaging system 30 includes a plurality ofindividual interlocking devices 38 that each extend between the core of a pair of adjacent rolls. Each interlockingdevice 38 secures a pair of interlocking rolls to each other such that the plurality of interlockingdevices 38 create a lattice pattern to provide stability for the pallet of rolls during assembly, packaging, shipment and disassembly of the pallet. - As can be seen in FIG. 5, more than one interlocking
device 38 can be positioned in acore 32 of anindividual roll 12. Thus, an individual roll can be interlocked with more than one adjacent roll such that the series of interlockingdevices 38 create a stabilized pallet of rolls. - Referring now to FIGS. 3 and 6, thereshown is the preferred embodiment of the interlocking
device 38 in accordance with the present invention. The interlockingdevice 38 is formed from a single sheet of die-cut cardboard or paperboard material. Thedevices 38 include a spanningsection 40 sized to extend between a pair of adjacent cores when the outer diameters of therolls 12 are positioned in contact with each other. - As shown in FIG. 3, the spanning
section 40 is connected between a pair ofvertical legs vertical legs section 40 between a pair of rolls. In the preferred embodiment of the invention, each of thevertical legs wings vertical legs section 40 has a length of approximately {fraction (7 3/8)} inches as measured between thefirst end 52 and thesecond end 54 of the spanningsection 40. - Referring back to FIG. 6, the interlocking
device 38 includes anintermediate fold line 50 that allows the length of the spanningsection 40 to be adjusted. In the embodiment of the invention illustrated in FIG. 6, thefold line 50 is {fraction (5 3/4)} inches from the first end. However, it should be understood that the position of thefold line 50 can be modified depending upon the preferred distance between the cores of the rolls to be stacked on a pallet. - Referring back to FIG. 6, each of the
vertical legs wings outer edges corner 63 to aid in guiding thevertical legs section 40 is approximately two inches in the preferred embodiment of the invention. Although specific measurements for the sections of the interlockingdevice 38 are presented, it should be understood that the physical dimensions of the interlockingdevice 38 can be modified depending upon the roll size and the configuration of the rolls on a pallet. The measurements given are not meant to be limiting but are merely presented for illustrative purposes. - As can be understood in a comparison of FIGS. 3 and 6, the interlocking
device 38 is die-cut from a single sheet of cardboard and is created in a flat, storage condition shown in FIG. 6. In the storage condition shown in FIG. 6, multiple interlockingdevices 38 can be stacked on top of each other and thus occupy a small space. Thus, before the interlockingdevices 38 are used, the interlocking devices can be compactly stacked and stored. - When the interlocking
device 38 is to be used, the interlockingdevice 38 is folded along thefirst end 52 and thesecond end 54 to define thevertical legs wings respective fold lines 56 and 58 (FIG. 6) such that the interlockingdevice 38 is in the operating condition shown in FIG. 3. As discussed previously, the interlockingdevice 38 can be folded alongline 50, depending upon the diameter of rolls being stacked utilizing the system of the present invention. - Referring back to FIGS. 3 and 4, assembly of a pallet of vertically-oriented rolls utilizing the
packaging system 30 of the present invention will now be described. Initially, one of therolls 12 a is positioned on a pallet in a vertical orientation. After thefirst roll 12 a has been positioned, asecond roll 12 b is placed adjacent to thefirst roll 12 a and an interlockingdevice 38 a is positioned between the two adjacent rolls to secure the rolls to each other. Anotherroll 12 c is then placed on the pallet and yet anotherindividual interlocking device 38 b is used to secure the newly placedroll 12 c to the prior placedroll 12 a. This process continues until the interlockingdevices 38 are arranged in a lattice pattern and the entire pallet of vertically-oriented rolls are assembled, as shown in FIG. 4. - Referring now to FIG. 5, once the entire pallet of vertically-oriented rolls are assembled, several of the rolls, such as
roll 12 c, receive multiple interlockingdevices 38. As shown in FIG. 5, roll 12 c includes three interlockingdevices 38 such that theroll 12 c aids in stabilizing more than one row of the rolls assembled on the pallet. As can be seen in FIG. 5, thewings devices 38 are received within theopen center 36 to hold the interlockingdevice 38 in place. In the pallet configuration shown in FIG. 4, the pallet includes four rows each including five rows of material. Alternatively, as illustrated in FIG. 7, the pallet can be arranged such that the pallet includes five rows of rolls where each row includes five rolls. In the packaging arrangement shown in FIG. 7, the rolls are closely spaced and provide an alternate method of packaging rolls on a pallet. In the packaging arrangement shown in FIG. 7, the interlockingdevices 38 are utilized in a lattice pattern to stabilize the rows and thus illustrate the flexibility of the packaging system of the present invention. - Once the pallet of rolls is assembled, as shown in FIGS. 4 and 7, the series of
individual interlocking devices 38 provide stability for the entire pallet such that the pallet can be shipped without fear of tipping of any of the individual rolls. - Once the pallet of rolls is at its desired location, each of the
rolls 12 can be removed without disrupting the stability of the remaining rolls on the pallet. For example, to removeindividual roll 12 d (FIG. 4), the interlockingdevices roll 12 d is only partially broken. Once the interlockingdevices roll 12 d, theroll 12 d can be lifted from the pallet while the lattice pattern between the remaining rolls on the pallet continues to stabilize the pallet to prevent tipping. This process is repeated for each of the rolls on the pallet until the pallet has been completely unloaded. - Referring now to FIGS.8-10, thereshown is a second embodiment of the packaging system of the present invention. In the second embodiment of the
packaging system 60, an alternate type of interlocking device is utilized to stabilize the rolls on the pallet. In the second embodiment of thepackaging system 60, a sheet ofplastic 62 is draped over the top ends of eachroll 12 as the rolls are added to the pallet. As illustrated in FIG. 9, after the sheet ofplastic material 62 has been installed, a backingmember 64, having a plurality of extendingtabs 66 extending from aflat face 67, is inserted into thecore 68 of theroll 12. As illustrated in FIG. 10, thetabs 66 includeend points 70 that pierce theplastic sheet 62. Once the backingmember 64 is in place, anend plug 66 is inserted into the core to lock the core in place relative to the sheet ofplastic material 62. - Referring back to FIG. 8, once the pallet has been assembled, the sheet of
plastic material 62 acts as an interlocking device between the individual rolls of material. - Once the pallet of rolls has been delivered to a desired location, each of the individual rolls can be removed from the pallet by cutting the
plastic sheet 62 around the roll being removed or by simply folding back the plastic sheet after thecore plug 66 andbacking member 64 have been removed. Once theplastic sheet 62 has been cut or folded, the individual roll can be removed and the backingmember 64 and end plug 66 discarded. - As can be understood in FIG. 8, when an individual roll is removed, the remaining portion of the
plastic sheet 62 maintains the stability of the remaining rolls to prevent the rolls from tipping. In the preferred embodiment of the invention, theplastic sheet 62 is formed from a clear material such that the plastic material can be cut or folded without damaging the rolls. - Although not illustrated in the Figures, another alternate embodiment of the invention is contemplated in which individual rubber band-type elements can be used between the core extensions of adjacent rolls. The rubber band elements would replace the
individual interlocking devices 38 shown in FIG. 3. It is contemplated that a rubber band device would extend between adjacent rolls and that several rolls in the pallet may have more than one rubber band extending around its core extension. Like the interlockingdevices 38 shown in FIG. 3, rubber bands would allow each individual roll to be removed separately while maintaining the stability of the entire pallet. - In addition, it is contemplated by the inventor that the cardboard or
paperboard interlocking devices 38 shown in FIG. 3 could be replaced by a plastic U-clip having a pair of vertical legs and a spanning section. A plastic U-clip would function identically to the interlockingdevices 38 shown in FIG. 3 and would provide the required stability and individual removability of the rolls of material. - Although several embodiments of the invention are described in the present disclosure, it is contemplated by the inventor that other interlocking devices are within the scope of the present invention. The interlocking devices of the present invention provide stability for a pallet of vertically-oriented rolls while allowing the rolls to be individually removed without disrupting the overall stability of the remaining rolls. Further, the packaging system of the present invention reduces the number of discarded components as compared to the prior art packaging system10 illustrated in FIG. 1.
- Having described the presently preferred embodiments, it is to be understood that the invention may be otherwise embodied within the scope of the appended claims.
