This disclosure relates generally to a spool packaging assembly, more particularly, a paperboard spool configured to transition between a retention position and an open position.
Filament products can be supplied to end users on storage spools. The filament product can include new filaments and/or existing filaments that are going to be left on a reel for any length of time. The storage spool can protect the filament product during shipping, handling, and general use.
With conventional storage spools, there are two commonly used methods for supplying the filament product. The filament is either directly wound onto the spool, or the filament is wound into a loose coil and placed onto the spool. Typically, fly fishing lines are packaged based on the latter method. The spool includes an arbor for supporting the filament and two flanges for retaining the filament on the arbor. To allow the loose coil to be placed onto the arbor, the spool can be separated into at least two parts, and the flanges can be separated from one another to allow the coil to be placed on the arbor. Enough clearance must be provided between the internal diameter of the coil and the outside diameter of the arbor of the spool to allow the coil to be loaded onto the arbor. However, multiple part spools have drawbacks. For example, there is a potential to pinch the filament between mating surfaces of the spool parts, which can ruin the filament product. Further, the multiple parts can inadvertently separate while in use at high speeds causing tangling, bending, or other damage to the filament. Also, many conventional storage spools are made of plastic, and are discarded after the filament has been dispensed.
The foregoing background discussion is intended solely to aid the reader. It is not intended to limit the innovations described herein. Thus, the foregoing discussion should not be taken to indicate that any particular element of a prior system is unsuitable for use with the innovations described herein, nor is it intended to indicate that any element is essential in implementing the innovations described herein.
The foregoing needs are met, to a great extent, by the spool assembly disclosed in the present application. There is a global push to reduce single use plastic products. The spool assembly disclosed herein comprises a single piece paperboard spool that is eco-friendly and solves the short comings of the multiple piece spool designs.
An aspect of the present disclosure provides a spool for supporting a roll of material. The spool comprises an arbor, a first flange, and a second flange. The arbor extends about an arbor axis and includes a plurality of arbor panels connected to each other and spaced about the arbor axis. The first and second arbor panels of the plurality of arbor panels each include a first arbor edge, and a third arbor panel of the plurality of arbor panels includes a second arbor edge. The first arbor edges of the first and second arbor panels are spaced from the second arbor edge of the third panel in an arbor direction, which is substantially parallel to the arbor axis.
The first flange includes a first plurality of flange panels. A first flange panel of the first plurality of flange panels is rotatably connected to the first arbor edge of the first arbor panel, and a second flange panel of the first plurality of flange panels is rotatably connected to the first arbor edge of the second arbor panel. The second flange is connected to the second arbor edge of the third arbor panel.
The first flange is configured to transition between a retention configuration and an open configuration. In the retention configuration, the first and second flange panels of the first plurality of flange panels extend from the respective first arbor edges to a retention height. In the open configuration, the first and second flange panels of the first plurality of flange panels extend from the respective first arbor edges to an open height. The retention height and the open height extend in a flange direction from the arbor axis. The flange direction is substantially perpendicular to the arbor axis. The retention height is greater than the open height such that in the retention configuration, the roll of material is substantially prevented from removal from the arbor along the arbor axis by the first and second flanges, and in the open configuration, the roll of material is removable from the arbor in the arbor direction.
Another aspect of the present disclosure provides a method of assembling a paperboard spool from a one-piece paperboard blank. The method comprises: connecting a first arbor panel of a plurality of arbor panels to a second arbor panel of the plurality of arbor panels, wherein the first and second arbor panels form at least a portion of an arbor that extends about an arbor axis; forming a first flange panel crease line between the first arbor panel and a first flange panel of a first plurality of flange panels such that the first flange panel is rotatable relative to the first arbor panel; and forming a second flange panel crease line between the second arbor panel and a second flange panel of the first plurality of flange panels such that the second flange panel is rotatable relative to the second arbor panel.
The first plurality of flange panels compose a first flange that is configured to transition between a retention configuration and an open configuration. In the retention configuration, the first and second flange panels of the first plurality of flange panels extend from the respective first and second arbor edges to a retention height. In the open configuration, the first and second flange panels of the first plurality of flange panels extend from the respective first and second arbor edges to an open height. The retention height is greater than the open height.
Another aspect of the disclosure provides a spool that holds an item that can be coiled. The spool includes a barrel and spaced flanges. The item to be carried by the spool is disposed on the barrel between the flanges. One of the flanges is collapsible to allow an item that is already coiled to be loaded onto the barrel. In the collapsed condition, the collapsible flange is substantially the same size in cross section as the barrel. In one configuration, the collapsible spool is tapered down in cross section away from the barrel to facilitate loading of the coiled item on the spool.
Another aspect of the disclosure provides a spool that is made from a foldable material such as a paperboard or a polymer board. The spool is provided in the form of a flat blank with fold lines scored, cut, or embossed. The spool is erected and adhesive and interlocking elements are provided to maintain the erected condition. In one configuration, the spool can be partially erected into an intermediate condition where it is flat for convenient storage and shipping. In this configuration, the final erection step does not require additional adhesive to complete the erection of the spool.
Another aspect of the disclosure provides a method for loading a coiled item on a spool which includes the steps of collapsing a flange of the spool to a cross section no larger than the cross section of the barrel, sliding the coiled item over the collapsed flange and onto the barrel, and then unfolding the collapsed flange to its expanded condition where it retains the coiled item on the barrel.
Another aspect of the disclosure provides a method for forming a spool wherein a blank is provided and erected to a generally flat intermediate condition with portions secured by adhesive. Later, after the adhesive is cured, the spool is erected into its erected condition using only interlocking connections that do not require adhesive.
Another aspect of the disclosure provides a paperboard spool for fly fishing line wherein the spool can be erected from a flat blank. The spool includes a barrel formed from four walls. Two flanges project outwardly from the outer perimeter of the barrel. The spool provides a collapsible flange that collapses to a loading condition wherein the collapsed flange is in the form of a pyramidal frustum formed by folding corner webs inwardly. The spool has an intermediate condition during its erection wherein all of the adhesive connections are made and wherein the spool can be placed in a substantially flat condition with the barrel walls being parallel and folded down to be substantially parallel with the flanges.

The arbor 102 extends about an arbor axis 90. In an aspect, the arbor axis 90 extends through a radial center of the arbor 102. The arbor 110 includes a plurality of arbor panels 110. Each of the arbor panels 110 is connected to each of the other arbor panels 110 in series. For example, a first arbor panel 110a is connected to a second arbor panel 110b. In an aspect, the plurality of arbor panels 110 comprises four panels (as illustrated), such that the arbor 102 forms a substantially rectangular cross-sectional shape when viewed along the arbor axis A. It will be appreciated that the arbor 102 can comprise a different number of panels. For example, the arbor 102 can comprise three panels or five or more panels.
Each of the arbor panels 110 includes a first arbor edge 112 and a second arbor edge 114. Each of the first arbor edges 112 is spaced from the respective second arbor edge 114 in an arbor direction A. The arbor direction A is substantially parallel to the arbor axis 90. Each of the arbor panels 110 further includes a third arbor edge 115 and a fourth arbor edge 117. The third arbor edge 115 of an arbor panel 110 is connected to a corresponding fourth arbor edge 117 of an adjacent arbor panel 110. For example, the third arbor edge 115 of the first arbor panel 110a is connected to the fourth arbor edge 117 of the second arbor panel 110b. Similarly, the third arbor edge 115 of the second arbor panel 110b is connected to a fourth arbor edge 117 of a third arbor panel 110c (see
In an aspect, the third and fourth arbor edges 115 and 117 of each arbor panel 110 extend in a direction substantially parallel to the arbor axis 90. The first, second, third, and fourth arbor edges 112, 114, 115, and 117 can define a substantially rectangular arbor panel 110. In an alternative aspect, the third and fourth arbor edges 115 and 117 are angularly offset from one another (e.g. not substantially parallel to one another), such that each arbor panel 110 includes a trapezoid shape, rhombus shape, combinations thereof, or other quadrilateral shape. In another alternative, each arbor panel 110 can include fewer or more than four arbor edges and can define a triangular shape, hexagon shape, combinations thereof, or other shape. In an aspect, each arbor panel 110 is substantially planar such that each arbor edge (e.g. edges 112, 114, 115, and 117) extends along a substantially similar plane.
The connection between the respective third and fourth arbor edges 115 and 117 of adjacent arbor panels 110 can include a crease line. The crease line can include a fold or bend in the spool 100 material. The crease line can allow each arbol panel 110 to rotate relative to an adjacent arbor panel 100 about the crease line. It will be appreciated that the connection between respective third and fourth arbor edges 115 and 117 can comprise other types of rotatable connections that allow the arbor panels 110 to rotate relative to adjacent arbor panels 110.
The first arbor edge 112 of each arbor panel 110 is rotatably connected to the first flange 104. The rotatable connection between each first arbor edge 112 and the first flange 104 can include a crease line. The crease line can include a fold or bend in the spool 100 material. In an aspect, the first arbor edge 112 of every arbor panel 110 is rotatably connected to the first flange 104. Alternatively, fewer than all the first arbor edges 112 of each arbor panel 110 are connected to the first flange 104. For example, an arbor 102 that includes four arbor panels 110 can have two first arbor edges 112 of two of the arbor panels 110 connected to the first flange 106, while two first arbor edges 112 of two of the other arbor panels 110 are not connected to the first flange 104.
The second arbor edge 114 of each arbor panel 110 is rotatably connected to the second flange 106. The rotatable connection between each second arbor edge 114 and the second flange 106 can include a crease line. The crease line can include a fold or bend in the spool 100 material. In an aspect, the second arbor edge 114 of every arbor panel 110 is rotatably connected to the second flange 106. Alternatively, fewer than all the second arbor edges 114 of each arbor panel 110 are connected to the second flange 104. For example, an arbor 102 that includes four arbor panels 110 can have two second arbor edges 114 of two of the arbor panels 110 connected to the second flange 106, while two second arbor edges 114 of two of the other arbor panels 110 are not connected to the second flange 106.
The connection between the first arbor edges 112 of each arbor panel 110 with the first flange 104 and the connection between the second arbor edges 114 of each arbor panel 110 with the second flange 106 can be substantially symmetric when viewed in a direction substantially perpendicular to the arbor axis 90. For example, each first arbor edge 112 and each second arbor edge 114 can be connected to the respective first flange and second flange 104 and 106 in a substantially similar manner. In an alternative aspect, each arbor panel 110 that has a first arbor edge 112 connected to the first flange 104 has a second arbor edge 114 that is not connected to the second flange 106. And each arbor panel 110 that has a second arbor edge 114 connected to the second flange 106 has a first arbor edge 112 that is not connected to the first flange 104. In this aspect, the first and second flanges 104 and 106 are circumferentially offset from each other when viewed along the arbor axis 90. It will be appreciated that other alternative connections between the arbor panels 110 and the first and second flanges 104 and 106 can be considered that are consistent with the aspects described herein.
The first flange 104 includes a first plurality of flange panels 116. The first plurality of flange panels 116 comprises a first inner plurality of flange panels 118 and a first outer plurality of flange panels 120. The first inner plurality of flange panels 118 extend from the arbor 102 to the first outer plurality of flange panels 120. The first outer plurality of flange panels 120 extend to an end 121 of the first flange 104.
Each of the first arbor edges 112 of the arbor panels 110 is rotatably connected to a respective one of the first inner plurality of flange panels 118. For example, the first arbor panel 110a is rotatably connected to a first inner flange panel 118a. Similarly, the second arbor panel 110b is rotatably connected to a second inner flange panel 118b. Each of the first outer plurality of flange panels 120 is rotatably connected to an edge of a respective one of the first inner plurality of flange panels 118. The rotatable connection between each of the panels 110, 118, and 120 can include a crease line formed in the material composing the spool 100.
The rotatable connection between each first arbor edge 112 of the arbor panels 110 and the respective one of the first inner plurality of flange panels 118 can extend in a direction that is substantially perpendicular to the arbor axis 90. Each of the first inner plurality of flange panels 118 can rotate between at least 90 degrees and 180 degrees relative to the respective arbor panel 110 to which the inner flange panel 118 is connected. For example, when one of the first inner plurality of flange panels 118 is rotated approximately 90 degrees relative to the respective arbor panel 110 to which it is connected, the inner flange panel 118 extends in a direction away from (e.g. radially outward) the arbor axis 90 such that the flange panel 118 is substantially perpendicular to the arbor axis 90. When one of the first inner plurality of flange panels 118 is rotated approximately 180 degrees relative to the respective arbor panel 110 to which it is connected, the inner flange panel 118 extends in a direction substantially parallel to the arbor axis 90. In this orientation (e.g. 180 degree rotation), the inner flange panel 118 can be substantially planar with (e.g. align along the same plane) the respective arbor panel 110 to which it is connected. It will be appreciated that each of the first inner plurality of flange panels 118 can rotate to an angle relative to the respective arbor panel 110 to which it is connected that is greater than 180 degrees and less than 90 degrees to facilitate receiving and retaining the roll of material 108 onto the arbor 102, as further described below.
With reference to
The first plurality of flange panels 116 further includes the second inner flange panel 118b and a second outer flange panel 120b rotatably connected to the second inner flange panel 118b at an edge 122b. The second inner flange panel 118b can be connected to the second outer flange panel 120b in a substantially similar manner as the first inner flange panel 118a is connected to the second outer flange panel 120a as described above. In an aspect, the first outer flange panel 120a is rotatably connected to the second outer flange panel 120b. In an aspect, the rotatable connection between the first and second outer flange panels 120a and 120b is defined by a crease line 124. It will be appreciated that the rotatable connection between the first and second outer flange panels 120a and 120b can be defined by alternative structures, such as, multiple crease lines 124, flexible panels, combinations thereof, or still other structures. The first and second inner flange panels 118a and 118b and the first and second outer flange panels 120a and 120b can be configured such that the first inner flange panel 118a and the first outer flange panel 120a are mirror images of the second inner flange panel 118b and the second outer flange panel 120b.
With reference to
The first plurality of flange panels 116 can further include a third inner flange panel 118c, a fourth inner flange panel 118d, a third outer flange panel 120c, and a fourth outer flange panel 120d. The third and fourth inner flange panels 118c and 118d and the third and fourth outer flange panels 120c and 120d can be configured substantially similarly to the first and second inner flange panels 118a and 118b and the first and second outer flange panels 120a and 120b, respectively. Each of the third and fourth inner flange panels 118c and 118d can extend from a respective first arbor edge 112 of the arbor. Each of the third and fourth outer flange panels 120c and 120d can extend from the respective third and fourth inner flange panels 118c and 118d.
With reference to
In an alternative or additional aspect, at least one of the first plurality of inner flange panels 118 can be configured to connect with a respective one of the first plurality of outer flange panels 120. The connection between at least one of the first plurality of inner flange panels 118 and the respective one of the first plurality of outer flange panels 120 can selectively retain the first flange 104 in the retention configuration, as further described below.
The first flange 104 is configured to transition between the retention configuration (see
The retention height is greater than the open height to allow the roll of material 108 to be inserted onto and about the arbor 102 (see
In the retention configuration, the roll of material 108 is substantially prevented from removal from the arbor 102 along the arbor axis 90 by the first and second flanges 104 and 106 (see
The first flange 104 can be transitioned from the retention configuration to the open configuration by rotating one or more of the first plurality of flange panels 116. For example, the first and second inner flange panels 118a and 118b can be rotated from approximately 90 degrees relative to the respective arbor edge 112 to an angle of greater than approximately 90 degrees. In an aspect, the first and second inner flange panels 118a and 118b can be rotated to approximately 180 degrees. Rotation of the first and second inner flange panels 118a and 118b causes the respective first and second outer flange panels 120a and 120b to rotate about the respective edges 122a and 122b. As the first and second inner flange panels 118a and 118b and the first and second outer flange panels 120a and 120b rotate from 90 degrees toward 180 degrees relative to the arbor 102, the first flange 104 extends axial outward from the arbor 102 in the arbor direction A. When the first and second inner flange panels 118a and 118b reach the open height, the roll of material can be positioned on the arbor 102 by moving the roll of material along the arbor axis 90.
To transition the first flange from the open configuration to the retention configuration, the first and second inner flange panels 118a and 118b are rotated toward the 90 degree position relative to the respective arbor panel 110. As the first and second inner flange panels 118a and 118b and the first and second outer flange panels 120a and 120b rotate toward 90 degrees relative to the arbor 102, the first flange 104 retracts axially inward toward the arbor 102 in a direction opposite the arbor direction A. After the first and second inner flange panels 118a and 118b reach the retention height H, the roll of material 108 is retained on the arbor 102.
The first flange 102 can be selectively retained in the retention configuration by connected the first connect element 126 to the second connect element 128. In an aspect, in the retention configuration of the first flange 104, a surface of the first outer flange panel 120a abuts against a surface of the first inner flange panel 118a, and a surface of the second outer flange panel 120b abuts against a surface of the second inner flange panel 118b. One or both of the sets of abutting surfaces of the first inner and outer flange panels 118a and 120a and the second inner and outer flange panels 118b and 120b can include connect elements (see e.g.
It will be appreciated that the third and fourth inner flange panels 118c and 118d and the third and fourth outer flange panels 120c and 120d can be moved and/or transitioned substantially similarly as the first and second inner flange panels 118a and 118b and the first and second outer flange panels 120a and 120b to transition the first flange 104 between the retention configuration and the open configuration.
It will be appreciated that the second flange 106 can be configured substantially similarly to the first flange 104. For example, the second flange 106 can include a second plurality of flange panels 132. The second plurality of flange panels 132 can transition the second flange 106 between a retention configuration to retain the roll of material 108 on the arbor 102, and an open configuration to allow the arbor 102 to receive the roll of material 108 and to allow the roll of material 108 to be removed from the arbor 102. It will be appreciated that the first and second flanges 104 and 106 can be configured differently from one another. For example, the second flange 106 can be configured such that the second flange is retained or locked in the retention position. To receive and remove the roll of material 108 from the arbor 102, the first flange 104 is selectively transitioned between the retention and open configurations.
The precise appearance and structure defined by the spool 100 can be modified without departing from the scope of the present disclosure. For example, the connect elements 126 and 128 can be located on different panels of either of the first and second flanges 104 and 106. In another alternative, the spool 100 could have fewer or more inner panels and/or fewer or more outer panels configured to transition between retention and open configurations. In another alternative aspect, each of the outer flange panels 120 can be connected to each adjacent outer flange panel 120.
With reference to
The arbor 302 includes a plurality of arbor panels 310. Each of the arbor panels 310 includes a substantially triangular shape. Each of the arbor panels 310 is connected to each adjacent arbor panel 310 in series about an arbor axis 290. In an aspect, every other arbor panel 310 spaced about the arbor axis 290 includes a first arbor edge connected to the first flange 304. Each of the other every other arbor panels 310 spaced about the arbor axis 290 includes a second arbor edge that is connected to the second flange 306. For example, a first arbor panel 310a and a third arbor panel 310c of the plurality of arbor panels 310 each include a first arbor edge. The first arbor edge of both the first and third arbor panels 310a and 310c is rotatably connected to a respective flange panel of a plurality of flange panels 316. A second arbor panel 310b of the plurality of arbor panels 310 is positioned circumferentially between the first and third arbor panels 310a and 310c. The second arbor panel 310b includes a second arbor edge that is connected to the second flange 306. The configuration of the plurality of arbor panels 310 can circumferentially offset the first flange 304 from the second flange 306 when viewed along the arbor axis 290 (see
The method of assembling the spool 500 includes forming crease lines 511 in the blank 501 between each of the plurality of arbor panels 510. Each of the crease lines 511 can allow each arbor panel 510 to rotate relative to an adjacent arbor panel 510. Crease lines 513 can be formed between each of the plurality of arbor panels 510 and respective inner flange panels of a plurality of inner flange panels 518. Each of the crease lines 513 can allow each of the plurality of inner flange panels 518 to rotate relative to a respective one of the plurality of arbor panels 510. Crease lines 515 can be formed between each of the plurality of inner flange panels 518 and respective outer flange panels of a plurality of outer flange panels 520. Each of the crease lines 515 can allow each of the plurality of outer flange panels 520 to rotate relative to a respective one of the plurality of inner flange panels 518. A crease line (see e.g. crease line 124 in
Spool 2 can be folded into the intermediate condition of
Spool 2 can be erected from the flat condition shown in
Once in the erected condition, spool 2 can be loaded with a coiled item either by winding the item around barrel or by sliding the coiled item over collapsible flange 8. Some coiled items such as fly fishing line are coiled during manufacturing and it is not desirable to uncoil the line from its condition and rewind it onto barrel 4. As such, collapsible flange 8 can be changed to its collapsed condition shown in
Barrel 4 includes four walls 20, 22, 24, and 26 with walls 22 and 26 being formed by barrel half walls 28 that have mechanically interlocking end portions 30. In some configurations, a user can optionally use adhesive to secure the interlocking end portions 30. The interlocking end portions 30 can include, for example, corresponding snap-fits, interference fits, or other corresponding connection or interlocking portions. Walls 20 and 24 and parallel and hinged at or to flanges 6 and 8. These hinges allow flange 8 and barrel 4 to pivot down to the substantially flat condition when they are in the intermediate condition.
Fixed flange 6 includes two main layers and an attachment flange 32 used to anchor barrel wall 24. Attachment flange is adhered to a portion of the inner surface of flange 6 inside barrel 4. The two main layers of flange 6 include an outer panel 34 (defining a portion of opening 10) and first 36 and second 38 inner panels which are folded against and adhered to outer panel 34. First inner panel overlaps and defines a portion of opening 10. Barrel wall 20 is connected to an inner end of second inner panel 38. Flange 6 can be octagonal.
Collapsible flange 8 includes two main layers defined by an outer panel 44 and first 46 and second 48 inner panels which are adhered to outer panel. First inner panel 46 is connected to the top of barrel wall 20 and second inner panel 48 is connected to the top of barrel wall 24.
Collapsible flange 8 can include a rectangular or square central portion 50 from which four tapered subpanels 52 extend. It will be appreciated that fewer or more subpanels 52 can extend from the central portion 50.
The spool assemblies disclosed herein can comprise a single piece paperboard spool that is eco-friendly and solves the short comings of the multiple piece spool designs.
