The present invention relates to labels and, more particularly, to a uniquely configured container label having a piggyback panel. The container label is specifically configured for mounting on a container utilizing conventional labeling machinery.
In the prior art there exist container labels comprised of a base panel carrying a typically smaller piggyback panel. The piggyback panel is generally centered on the base panel within an interior region of the base panel. The piggyback panel is coated with an adhesive such as a pressure-sensitive adhesive allowing it to adhere to the base panel. The base panel is typically fabricated from paper stock that is permanently bonded on one side to a container such as a beer bottle. The opposite side of the base panel may be prepared so that it has a reduced amount of tackiness. For example, the opposite side of the base panel may be coated with a release layer such as silicone. The piggyback panel is mounted such that a portion of the marking indicia that is printed on the base panel is not visible unless the piggyback panel is peelably removed.
Because the base panel is coated with the release layer, the pressure-sensitive adhesive on the piggyback label has a reduced affinity for the base panel such that the piggyback panel is releaseably bonded to the base panel. In this configuration, the piggyback panel may be removed such that the marking indicia underneath the piggyback panel may be viewed. A consumer may purchase the container bearing such a container label and may peel back the piggyback panel from the larger base panel in order to reveal the marking indicia otherwise hidden by the piggyback label. The marking indicia may consist of text or graphics, or a combination thereof. The release layer on the base panel allows a user to repeatedly and alternately peelably remove and re-adhere the piggyback panel to the base panel. Container labels that are configured in such a manner include two layers of material in areas where the piggyback panel covers the base panel. However, remaining areas of the container label, such as the perimeter area, are comprised of only a single layer of material.
In automated labeling machinery, container labels are applied to containers in assembly line fashion at a high rate of speed. In certain types of labeling machinery, the container labels are mounted in a stacked formation within a stationery label magazine. The stack of container labels is held within the label magazine by guide fingers that are affixed to an end of the label magazine. The guide fingers are disposed around the perimeter of the foremost container label. A spring biases the stack of container labels against the guide fingers such that the foremost container label is advanced toward the end of the label magazine with the guide fingers preventing inadvertent dispensing of the container labels. A rotor comprised of multiple glue pallets is rotated past the label magazine. The foremost container label is held at its perimeter against the guide fingers until the glue pallet rotates past the container label, picking up the foremost container label in the magazine rack due to a coating of adhesive on the container label. The glue pallet then carries the container label past a moving conveyor of containers whereupon the container label is then transferred to the surface of one of the containers.
Ideally, the label magazine dispenses the container labels in singulated fashion such that only a single container label is transferred to each glue pallet as the glue pallet rotates past the label magazine. Container labels having a uniform thickness throughout permit the use of conventional labeling machinery wherein only a single container label is dispensed to each glue pallet. However, as was mentioned above, container labels carrying a piggyback panel have increased thickness where the piggyback label covers the base panel as compared to the thickness at the perimeter area. Due to this disparity in thickness, the biasing spring in the label magazine forces multiple container labels out of the label magazine each time a glue pallet passes the label magazine. The multiple dispensing of container labels leads to binding or jamming of the labeling machinery, mislabeling of the containers and a waste of unused container labels. Furthermore, the jamming may potentially cause damage to the labeling machinery and require that the labeling machinery be shut down, reducing production output.
The present invention specifically addresses and alleviates the above referenced deficiencies associated with the use of container labels having piggyback panels. More specifically, the present invention allows for the use of container labels having piggyback panels in label magazines of conventional labeling machines by equalizing the container label thickness between the perimeter and the interior region such that container labels are dispensed from the label magazine in one-at-a-time fashion.
The container label comprises a base panel having a series of perimeter, tabs and a piggyback panel disposed thereupon. The perimeter tabs advantageously allow for the use of the container labels in a label magazine of a conventional labeling machine. The base panel material may be a paper material such as conventional paper stock. The base panel has a base panel top surface, a base panel bottom surface and a base panel perimeter. The base panel perimeter defines a first printed area of the base panel top surface adapted for printing marking indicia therewithin. The first printed area effectively encompasses the entirety of the base panel top surface. A majority of the base panel top surface is also coated with a release layer such as silicone. However, a series of elongate perimeter zones spaced along the base panel perimeter are free of the release layer. Such perimeter zones are also free of marking indicia. Importantly, the perimeter zones are generally spaced around the base panel perimeter so as to correspond to the placement and spacing of guide fingers of the label magazine such that the container labels are restrained at each of the perimeter tabs by a corresponding one of the guide fingers.
The series of perimeter tabs are sized complimentary to and are aligned with the perimeter zones. Each one of the perimeter tabs defines a perimeter tab bottom surface that is coated with an adhesive layer such as a pressure-sensitive adhesive. Because the perimeter zones are free of the release layer and marking indicia, the adhesive layer permanently bonds the base panel to the perimeter tab. Importantly, it is preferable that no less that two of the perimeter tabs are disposed on a side of the base panel perimeter such that the perimeter tabs correspond to the placement of the guide fingers of the label magazine from which the container labels may be dispensed.
The piggyback panel may be of a generally smaller size than the base panel perimeter. The piggyback panel has a piggyback panel bottom surface that is coated with the adhesive layer. However, because the base panel top surface is coated with the release layer, the adhesive layer on the piggyback panel bottom surface has a reduced affinity for the base panel such that the piggyback panel may be alternately peeled away and reapplied to the base panel. When the piggyback panel is partially peeled away from the base panel, an area of the base panel top surface that is otherwise hidden by the piggyback panel is exposed. The piggyback panel may also be reapplied to the base panel to cover up the area of the base panel.
Although the piggyback panel may have a circular shape with the base panel having an orthogonal shape, it is contemplated that there are many shapes that may be utilized for the piggyback panel and the base panel. However, the variety of configurations in which the base panel may be shaped is more limited as the shape of the base panel perimeter must be compatible with the cross-sectional shape of the label magazine of a labeling machine. The piggyback panel perimeter may include a peel tab protruding outwardly therefrom to aid in peeling the piggyback panel away from the base panel in order to expose graphics that may be hidden underneath the piggyback panel.
These, as well as other features of the present invention will become more apparent upon reference to the drawings wherein:
Referring now to the drawings wherein the showings are for purposes of illustrating the present invention and not for purposes of limiting the same,
In the container label 16 shown in
A majority of the base panel top surface 52 is coated with a release layer 82 except for a series of elongate perimeter zones 56 spaced along the base panel perimeter 54 that are free of the release layer 82. Such perimeter zones 56 are also free of marking indicia. Importantly, the perimeter zones 56 are generally located around the base panel perimeter 54 corresponding to the placement of guide fingers 44 of the label magazine 38 as shown in FIG. 6. The release layer 82 may be a coating of a release compound such as silicone that is sprayed on the base panel top surface 52 excluding the areas defined by the perimeter zones 56.
The series of elongate perimeter tabs 58 are sized complimentary to and are aligned with the perimeter zones 56. As can be seen in
Each one of the perimeter tabs 58 defines a perimeter tab bottom surface 62 that is coated with an adhesive layer 80. Such adhesive layer 80 may be a pressure-sensitive adhesive. Because the area of the base panel top surface 52 excludes the release layer 82 in the perimeter zones 56, the adhesive layer 80 on the perimeter tab bottom surface 62 permanently bonds the base panel 50 to the perimeter tab 58. The series of elongate perimeter tabs 58 may be substantially identically shaped although it is contemplated that differently shaped perimeter tabs 58 may be utilized on a single one of the base panels 50.
The perimeter tabs 58 may be shaped and placed in a manner shown in
As shown in
An example of the application of the container label 16 can be seen in
As is shown in
As can be seen in
Referring to
Turning now to a discussion of the method of making the container labels 16 of the present invention,
The paper stock 86 is then fed to a release layer print head 110 wherein the release layer 82 is applied to a substantial portion of the paper stock top surface 90 except within areas defined by the series of elongate perimeter zones 56 spaced along the base panel perimeter 54. The perimeter zones 56 are thus free of the release layer 82. Such perimeter zones 56 correspond to those described above and can be seen in
As is shown in
After the peel-off 96 liner is removed, the substrate 100 is laminated onto the paper stock 86 such that the substrate bottom surface 104 contacts the paper stock top surface 90 to form a label assembly 106. Due to the coating of the release layer 82 on a substantial portion of the paper stock top surface 90, the pressure-sensitive adhesive on the substrate bottom surface 104 forms a releasable bond between the substrate 100 and the paper stock 86. However, in areas defined by the perimeter zones 56 that are free of the release layer 82, the pressure-sensitive adhesive on the substrate bottom surface 104 forms a permanent bond between the substrate 100 and the paper stock 86.
After the laminating step, the label assembly 106 is fed to a first substrate print head 112. Optionally, a second substrate print head 114 may be included in the label press 84. However, as in the paper stock print head 108, any number of substrate print heads may be included in the label press 84 depending on the variety of colors that are to be printed. The first substrate print head 112 and the second substrate print head 114 are utilized to print marking indicia within a second printed area 76 on the substrate top surface 102. The second printed area 76 can be seen in FIG. 3. The second printed area 76 generally corresponds to the area defined by the piggyback panel perimeter 66. However, in addition to the area defined by the piggyback panel perimeter 66, the second printed area 76 may additionally include the areas defined by the series of perimeter tabs 58.
The first and second substrate print heads 112, 114 may be configured to print marking indicia on the perimeter tabs 58 and the piggyback panel 64 in a manner similar to the marking indicia of the first printed area 74. In this manner, the appearance of the container label 16, as defined by the colors, text, and graphics thereof, may be aesthetically consistent between the base panel 50, the perimeter tabs 58 and the piggyback panel 64. As was earlier mentioned, the paper stock print head 108 is configured to print within the first printed area 74. The first printed area 74 generally corresponds to an area defined by the base panel perimeter 54 excluding the perimeter zones 56. The third printed area 78 may be disposed within the first printed area 74 and may be completely or partially hidden by the piggyback panel 64, as is shown in FIG. 3.
Referring still to
The first die cutter 116 also cuts the substrate 100 to form the series of elongate perimeter tabs 58 in a manner wherein the perimeter tabs 58 are sized complimentary to and are generally aligned with the perimeter zones 56. The substrate 100 may be cut such that the perimeter tabs 58 are located in a manner similar to that shown in
Such perimeter tabs 58 of shorter length may be generally aligned with the perimeter zones 56 as shown in FIG. 1. However, preferably no less that two of the perimeter tabs 58 are disposed along each of the base panel sides 122 such that the perimeter tabs 58 generally correspond to the guide fingers 44 of the label magazine 38 from which they may be dispensed, as can be seen in
After leaving the first die cutter 116, the label assembly 106 is fed to a remainder label stock removal station 116a as shown in FIG. 7. The remainder label stock removal station 116a is configured for removing or peeling the remainder label stock portion of the substrate 100 away from the paper stock top surface 90 leaving the piggyback panel 64 and the perimeter tabs 58 attached to the paper stock 86. As was mentioned earlier, due to the coating of the release layer 82 on the base panel top surface 52, the piggyback panel 64 is releaseably bonded to the paper stock 86 while the perimeter tabs 58 are permanently bonded to the paper stock 86. The remainder label stock removal station 116a may comprise a take-up roll, as is shown in
After leaving the remainder label stock removal station 116a, the label assembly 106 is comprised of the web of paper stock 86 with portions of the substrate 100 being formed as repeating patterns of the piggyback panel 64 and the perimeter tabs 58. The label assembly 106 is then fed to a second die cutter 118 that cuts through the paper stock 86 in order to form the base panel 50, leaving a remainder paper stock portion (not shown). The base panel perimeter 54 defines the final shape of the container label 16. The substrate 100 is cut such that the base panel perimeter 54 encompasses the perimeter tabs 58 and the piggyback panel 64.
A remainder paper stock removal station 118a may be included in the label press 84, as can be seen in FIG. 7. The remainder paper stock removal station 118a is configured for removing or peeling the remainder paper stock portion away from the paper stock top surface 90 leaving the piggyback panel 64 and the perimeter tabs 58 attached to the paper stock 86. Like the remainder label stock removal station 116a, the remainder paper stock removal station 118a may comprise a take-up roll, as is shown in
As was indicated above, the first die cutter 114 may form the base panel 50 into a substantially orthogonal shape defining four base panel sides 122 thereof. Such an orthogonal shape of the base panel 50 may comprise a rectangular shape as is shown in
Turning now to
Also shown in
The label magazine 38 is also shown in
As can be seen in
As the rotor 26 continues to rotate past the label magazine 38, the adhesion between the glue and the base panel bottom surface 124 overcomes the restraining force of the guide fingers 44 upon the perimeter tabs 58, allowing for the gradual removal of the foremost one of the container labels 16 from the label magazine 38. Advantageously, the perimeter tabs 58 provide an additional layer of material such that the total thickness of the container label 16 in the area of the piggyback panel 64 is substantially equal to the total thickness in the areas of the perimeter tabs 58. This substantially equalized thickness allows the guide fingers 44 to restrain the container labels 16 against the biasing force of the spring 48 such that the dispersal of more than one container label 16 at a time is prevented. In this manner, only a single container label 16 is dispensed onto each of the glue pallets 28.
Referring still to
The container label 16 is then applied to a container 12 by intimate contact of the container 12 surfaces with the glue-coated base panel bottom surface 124 as the container 12 bears against the resilient pressures pad 22. Protruding edges of the container label 16 are then smoothed down into conformity with the container 12 by rollers or brushes 18 located downstream of the gripper cylinder 20 in the direction of movement of the container conveyor 14. After the adhesive layer 80 that is interposed between the base panel 50 to the container 12 has formed a permanent bond therebetween, the piggyback panel 64 may be partially peeled away from the base panel 50, exposing the third printed area 78 of the base panel top surface 52 that is otherwise hidden underneath the piggyback panel 64. The piggyback panel 64 may also be reapplied to the base panel 50 to cover up the third printed area 78.
