    CROSS REFERENCE TO RELATED ORDERS
    [0001] This application claims the benefit of U.S. patent application serial number 61/539,784 filed September 27, 2011, the description of which is hereby incorporated by reference as if set forth herein in its entirety. FUNDAMENTALS OF THE INVENTION
    [0002] This invention relates to containers and, more particularly, the marking of components of metal cans with machine readable information.
    [0003] Two-piece metal cans include a can body to which one end of the can is attached through a seam. Commercial two-piece beverage cans are formed by a stamping and ironing process that forms the sidewall of the body integral with the base. Three-piece metal cans include a cylindrical body, each end of which has a can end attached by a seam.
    [0004] Two-piece beverage cans are produced in vast quantities for use in beverages and foods; Three-piece beverage cans are produced in vast quantities for food uses. In this way, can components have to be produced at high speeds.
    [0005] Conventional beverage cans and many easy-open food cans have pull tabs. Pull tabs are formed from sheet metal in a tab press. Because of the quantities required, conventional tab presses form multiple tabs at a time in two, three, or four tab lanes.
    [0006] Typically, pre-varnished aluminum coil is fed into a shell press to form can end shells. A pre-varnished aluminum coil is fed into a tab press to form the pull tabs. The wraps and pull tabs are combined in a converting press to form the unsewn can end.
    [0007] Decoration of can ends, especially pull tabs, is known. For example, US patent number 6,105,806 describes laser engraving or removing portions of a coating on a pull tab. US patent number 6,498,318 recognizes difficulties in marking metal cans and describes the use of metal pull tab load ablation.
    [0008] You are aware of a conventional commercial system for laser engraving of pull tabs that includes a CO2 laser that often operates at around 100W. Each lane of a tab press has its own laser so that the tab press can operate at about 700 tabs per minute with a laser with a resolution or dimension of approximately 100 microns. Typically, a dark colored varnish is removed by the laser to expose the bare aluminum in the form of a simple logo or a few characters. Limiting the process speed is also a limiting the amount of decoration.
    [0009] Laser marking of coatings is employed for flexible and cardboard packaging for various marking applications. Typically, a thermally active pigment is loaded into a clear or light-colored varnish, and a CO2 laser induces a color change. For example, a laser can be applied to a white lacquer label to display black text. Laser marking systems of this type are from Sun Chemical under the trade name Sunlase and employ a 100 micron YAG laser. SUMMARY OF THE INVENTION
    [00010] A high-speed, high-resolution laser marking decoration process is provided for can ends, especially can end center panels, can end mandrel walls, and can pull tabs. Can ends and pull tabs resulting from the process are also provided.
    [00011] The method of decorating can ends comprises the steps of: providing a can end substrate, such as a can end center panel, mandrel wall, and/or pull tab, of a metallic material, such as like aluminum, or, in some cases, steel; coating at least a portion of the can end substrate, preferably with a varnish, which includes a photonically active component; and applying a laser to the coated substrate to change the appearance of at least a portion of the photonically active component substantially without burning, chemical etching or varnish ablation, thereby forming an image.
    [00012] Preferably, the photonically active component includes a thermally active pigment. Preferably, the change in appearance is a change in color, such as from transparent or light in color to an opaque or darker color.
    [00013] Preferably, a CO2 laser is employed that has a beamwidth that is less than about 50 microns, more preferably not more than about 30 microns, more preferably not more than about 10 microns, and preferably about 5 microns. In this way, the image can be formed by dots that have a dimension of less than about 50 microns, preferably not more than about 30 microns, more preferably not more than about 10 microns, and preferably about 5 microns. In this way the image can be formed from dots that have a dimension of less than approximately 50 microns.
    [00014] It has been contemplated that the laser marking process can be applied to the end load coil or tab load, applied to the tabs after the tab press before the converting press, applied to the end wraps after the tab press casing before the converting press, or after the converting press at the unsewn can end.
    [00015] It has been conjectured that the decorated ends may be adequate to withstand pasteurization up to 75°C for 20 minutes, such as what can be found by the beverage can ends after sewing. Also, it has been conjectured that the decorated ends may be adequate to withstand retort temperatures of up to 131 °C for 90 minutes, such as might be encountered by food can ends after sewing. In this way, the inventive method includes the steps of pasteurization or retort.
    [00016] One end of the decorated can comprises: an end casing and a pull tab, each of the end casing and the pull tab comprising preferably aluminum, but possibly also steel, and a liner, the liner comprising a varnish and a photonically active component; and an image applied to at least one of a center panel of the end casing and an underside of the pull tab, the image formed by applying a laser that changes the appearance of at least a portion of the photonically active component substantially without burning. , chemical etching or varnish ablation.
    [00017] Preferably, the image is a color that is darker than the varnish. Also, preferably, the image may be formed by dots, and the dots have a dimension of less than about 50 microns, preferably not more than about 30 microns, more preferably not more than about 10 microns, and preferably about 5 microns.
    [00018] Also, a decorated can end that has machine readable codes such as QR codes on the center panel is provided. The ends have (i) an unopened configuration in which the end is sealed and (ii) an open configuration in which the contents of the beverage can are accessible. The end of the can comprises an end casing and a pull tab. The pull tab has an orientation that is approximately parallel to a center panel of the end casing in the unopened configuration, and is capable of being actuated into an upright position by lifting one end of the pull tab to break a notch in the center panel. and in this way reach the open configuration. Preferably, the end of the can is an end of the aluminum beverage can. Ends from other materials or uses may also be employed, such as aluminum or steel ends for food cans. The term "vertical portion" is used to describe the position of the pull tab at which breakage and opening of the serving mouth panel of a beverage end occurs. When used with food can ends, it is the position of the pull tab at which opening of the relevant portion of the panel occurs.
    [00019] The various images, such as QR codes distributed around a rivet that couples the tab to the center panel, are located in a center panel of the end casing, each of the images being machine readable. The various images are located on the center panel in such a way that the pull tab hides a portion of each of the images, regardless of the rotational position of the pull tab. Thus, none of the various images are readable when the beverage can is in its unopened configuration. Then, at least one of the images is completely exposed, intact and capable of being read by a machine when the tab is actuated to its vertical portion position, even if the end tear panel is displaced.
    [00020] Images can be formed from inkjet printing, laser engraving and/or by another means well-versed in the art. The end can be aluminum or steel. Images can also be formed by applying a laser that changes the appearance of at least a portion of a photonically active component substantially without burning, chemical etching, or ablation of the varnish.
    [00021] A method of providing information at one end of the canister described above is also provided. The method comprises the steps of: providing an end of the metal beverage can including: an end wrapper, a pull tab, and several images located on a center panel of the end wrapper, each of the images being machine readable, the plural images being located on the center panel in such a way that the pull tab hides a portion of each of the images, independent of the rotational position of the pull tab such that none of the plural images are readable; and lifting one end of the pull tab until the pull tab is partially vertical to break a notch in the center panel, whereby, in the partially vertical position, at least one of the images is fully exposed, intact and readable. by a machine. The step of reading the image is performed with a machine while the tab is in a partially vertical position.
    [00022] A can end is provided which is capable of having (i) an unopened configuration in which the end is sealed and (ii) an open configuration in which, after application of the end to a can body, the contents of the can are accessible. The can end comprises: an end casing and a pull tab, the pull tab having an orientation that is approximately parallel to a center panel of the end casing in the unopened configuration, the pull tab being capable of being actuated to a partially vertical position lifting one end of the pull tab to break a notch in the center panel and thereby achieve the open configuration; and a machine readable image located on either the top or bottom side of the tab, the machine readable image having a size of no more than 6mm by 6mm.
    [00023] Preferably the machine readable code has a size of at least 2mm by 2mm, or at least 3mm by 3mm, and more preferably at least 4mm by 4mm and no more than 5mm by 5mm . Preferably, the machine readable code is a 14 by 14 module matrix barcode.
    [00024] Preferably, the machine that reads the information formed by the photon-sensitive ink is a portable wireless communication device, i.e. a smart phone of the type operated by ubiquitous common users (in other words, a "smart phone" such as an iPhone or phone operating on the Android operating system, equipped with a camera and the ability to tele-download applications), unlike the type of industrial one-dimensional or two-dimensional barcode readers that are employed for manufacturing or inventory purposes in an industrial environment or resale.

    [00039] The preferred marking system employs a conventional varnish in which a photonically active component, such as a pigment, dye, dye or ink compound or the like commercially available from Datalase, is added. A laser causes local change in appearance - that is, perceptible visual attributes - of the photonically active component and/or varnish. Several possible arrangements or modalities were contemplated in which the laser can be applied to photonically active components to create a color change, and thus form an image.
    [00040] It has been conjectured that images may be formed by laser markings applied to the ends of food or beverage cans or food or beverage pull tabs. Images broadly encompass decorations such as aesthetically pleasing logos, engravings or marks, or information such as text or QR codes.
    [00041] In this regard, Figure 1A illustrates a beverage can 10 which includes a can body 12 and a sewn can end 14. The end 14 includes a center panel 20 and a mandrel wall 22. The finished end is also includes a pull tab 26 attached to the center panel by a rivet. The pull tab is shown in its fully actuated position after it has broken the notch to create the serving opening. An image, which is a QR code 28, is located on the underside of tab 26 such that it would be visible only after actuation of tab 26. The present invention is not limited to beverage can ends, but encompasses other ends, such as the ends of food cans.
    [00042] Figures 1B and 1C illustrate a beverage can end with a configuration known in the industry as a DRT end. Figures ID and 1E illustrate a beverage can end with a configuration known in the industry as a Stolle end. Each of the modalities in the figures has a QR code printed on the underside of the tab.
    [00043] The present invention encompasses machine readable codes formed on the underside of the tab, on the upside of the tab (not shown in the figures), and both. Machine readable code encompasses matrix barcode or two-dimensional barcode, including but not limited to QR codes, data matrix codes, and inverses thereof.
    [00044] It has been determined that the two-dimensional code on either underside or upside of the tab is not more than approximately 6mm x 6mm, and above all preferably around 5mm x 5mm. The minimum size depends on the resolution and speed of the laser, printer, or other means to form the code, the speed of movement of the tab charge or dwell time of the stationary tab charge or tabs during marking, and the resolution capability of the wireless communication device and software to detect and process the data. Preferably, the minimum size is 2mm x 2mm, 3mm x 3mm, or 4mm x 4mm, allowing for predictable advances in technology.
    [00045] The machine readable code can be formed by any means, including a process of applying a laser to the photon-sensitive ink described herein, conventional laser engraving, conventional printing and the like. Co-pending US patent application 13/584521 entitled "Laser Marking System and Method" (Legal document number CC-5636/A0560US) describes a preferred method of marking while the tab load is continuously moving, and the present invention encompasses marking during the dwell period as the tab load moves to the tab press or as the tab moves to the converting press.
    [00046] As an example for using machine readable code (such as a QR code or data matrix code or their inverses) on a tab, a user can scan the code on the tab or anywhere on the container using a wireless communication device that connects to a software teletransfer location that automatically installs an application, commonly referred to as an "app." The app can display a splash screen on the wireless communication device and then display a conventional camera view on the device. If the app was previously teletransferred to the wireless communication device, teletransferring the app may not be necessary.
    [00047] The wireless communication device can then provide instructions to "sweep back the tab" (for example, where the tab is marked on the underside) and display a schematic showing where to find the machine-readable code. According to the instructions, the user can then scan the machine-readable code and a message may appear, such as "you've won - scan the can for reward!"
    [00048] The wireless communication device can then display another scheme with instructions to scan the container or a portion of the container that can function as a marker. The wireless communication device may, in this regard, interact with the recipient, such as displaying or teletransferring a video, playing or teletransferring a music track, providing reward points, requiring augmented reality as generally described in the co-pending patent application US 61/612,064, entitled, "Device, System, and Method for Facilitating Interaction Between a Wireless Communication Device and a Package having a Unique Identifier" (Legal document number CC-5616/A0556 US), or the like.
    [00049] Upside code and underside codes can also interact. For example, the code on the top panel might identify the game or category, and the code on the underside might provide additional information, such as identifying whether it has won a game or horse racing award.
    [00050] Figure 2 is a perspective view of a beverage can with multiple images on its central panel. In the image of Figure 2, the beverage can has a can end 14' that includes four QR codes 28' located around the center panel 20'. The codes 28' are oriented and spaced such that no code is completely unobstructed from above by the tab 26' regardless of the orientation or position of the tab while not actuated in its ready position, as manufactured.
    [00051] Each of figures 3A to 3F shows one end of the can with four QR codes 28'. In each figure, the codes are in the same position, but tab 26' is shown in various positions in Figures 3A to 3F to illustrate that, regardless of the position of tab 26', no code 28' is completely unobstructed from above.
    [00052] Each of Figures 4A to 4C shows a unique location of the group of four QR codes 28' with the tab in the fully actuated open position to illustrate that, regardless of the location of the codes 28', at least one code is fully exposed , uninterrupted or contiguous, and readable from above when the tab is fully actuated to its vertical position, such as upon opening. It should be understood that the number, spacing and size of codes may vary based on aesthetic and functional considerations. Furthermore, the embodiments shown in Figure 4A to 4C are not limited to employing a laser as described herein, but also encompass conventional processes such as ink jet printing to form QR codes as described.
    [00053] Figure 5 illustrates a beverage end 14" which includes a center panel 20", mandrel wall 22" and tab 26". A 28" image, which is multiple graphics, is located in the central 20" panel.
    [00054] The following is a description of the location of the application of the laser marking process in the process of manufacturing the end or pull tab, followed by a description of the preferred type of laser and a description of the photon-sensitive components that it is conjectured might be employed.
    [00055] As illustrated in figure 6, the laser marking process can be performed on the coil of tab load before it enters the tab press. Known methods can be employed to register the marked coil for accurate tab formation in relation to the images created by the laser marking. Thus, the output of the tab press in figure 6 would be tabs marked. As used herein, the term "coil" refers to coiled metal load and encompasses flat metal sheets that have been cut from the roll.
    [00056] As illustrated in figure 7, the laser marking process can be performed on the tabs after they are formed in the tab press, but before they are connected to the end casings in the converting press.
    [00057] As illustrated in figure 8, the laser marking process can be performed on the tabs and/or ends of the can, such as on the center panel or mandrel wall, after the ends are formed in the converting press.
    [00058] As illustrated in figure 9, the laser marking process can be performed on the can end filler metal in the coil before the metal enters the shell press. In this regard, laser markings may be formed on the coil portions of what will be formed on the central end panels and/or mandrel walls. Known methods can be employed to register the marked coil for accurate tab formation.
    [00059] As illustrated in figure 10, the laser marking process can be performed on the can end casings after they are formed in the casing press, but before they enter the converting press. Preferably, for each of the applications described herein, the tab loading spool and/or the end loading spool is supplied by the manufacturer with the pre-applied varnish. The present invention encompasses applying varnish at any stage prior to laser marking.
    [00060] Preferably, a CO2 laser having a characteristic beam size or width of less than 50 microns, more preferably less than 30 microns, more preferably less than 10 microns, and preferably approximately 5 microns. A CO2 laser of this type can be employed with the photon-sensitive components commercially supplied by Datalase.
    [00061] The inventors contemplate the use of a photonically active component in the can end varnish and/or pull tab that changes appearance when irradiated by a laser, preferably an infrared CO2 laser or a near infrared laser, to create images monochrome lasers in black or color. As used herein, the term "photonically active component" encompasses compositions of pigments or the like which are capable of changing appearance upon application of a laser. In other words, when a laser impinges on the material that includes the photonally active component, the photonically active component causes a change in appearance in the component or varnish in a way that is visually perceptible. The following are examples of photon-active component technology that one can surmise can be employed in present marking systems, methods, and products.
    [00062] Several pigments have been proposed to allow marking by applying a laser. For example, a plastic molding composition comprising a polyoxymethylene and char is described in patent applications WO-A-OO/43456, JP-A-11001065, EP-A0522370, EP-A-0797511 US patent numbers 5,053,440 and 5,350,792. A copper hydroxy phosphate for laser marking is described in US patents 5,928,780, 6,017,972 and 6,019,831. US Patents 5,489,639 and 5,884,079 describe additional suitable compounds.
    [00063] US patent number 7,485,403 describes oxyanions of a multivalent metal, especially ammonium octamolybdate, with the formula (NH4)4Mo8026 ("AOM"), in combination with polymer binders such as those with a labile group, absorb at the wavelength of CO2 laser light (10,600 nm) and undergo a color change because of a change in the oxidation state. The blend is not at temperatures typically found in pasteurization.
    [00064] Also, several compositions that change color or otherwise produce a change in visual appearance by applying a NIR laser have been described. For example, W005/068207 describes the use of NIR laser radiation (ie, at 800 to 2000 nm) to initiate a color change reaction when an NIR-absorbent metal salt is used in combination with a substance that normally passes through a color change reaction at a much longer wavelength (-10,600 nm), eg AOM. Various metal salts are described, including copper salts such as copper hydroxy phosphate.
    [00065] JP8127670 describes the use of reduced titanium oxide compounds for incorporation in thermoplastic, for laser marking.
    [00066] U.S. Patent No. 5,578,120 describes the use of an inorganic laser beam absorbing substance and a dye. Examples of the dyes which can be used include those mentioned in JP-A-49-82340, including zinc oxide semiconductors and titanium dioxide semiconductors.
    [00067] U.S. patent no. 5,911,921 describes the use of non-stoichiometric ytterbium phosphate to produce NIR-absorbent inks, such as for anti-theft bar code printing.
    [00068] US patent application number US20100015558A1 describes a non-stoichiometric compound such as r-ITO, for example, in the form of a nanopowder, as an absorber of near-infrared radiation in the region of 900 to 2,500 nm to create a contrasting image when incorporated, for example, in an AOM-based ink formulation and subjected to laser radiation in the near-infrared region of the electromagnetic spectrum (780 to 2,500 nm). A metal salt as an IR-functional color descriptor/absorber material which, upon absorption of radiation from a laser source, can directly produce a color forming reaction when in combination with a component that would otherwise undergo the desired reaction by irradiation at a longer wavelength. For example, it can be used in combination with an anionic oxymetal component in an applied coating to generate a distinct color image. Alternatively, a color forming component is used to generate a distinct image. A fiber, diode, diode array or CO2 laser for imaging applications can be used.
    [00069] U.S. patent no. 6,602,595 describes the use of non-stoichiometric nanomaterials for use in paints, such as r-ITO (reduced indium tin oxide), which acts as an NIR absorber.
    [00070] W02009093028A2 describes a compound that will undergo a color change upon irradiation. The compound has the general structure: X-C=C-C=C-Y-(CO)n-QZ, wherein X is H, alkyl or -Y-(CO)n-QW; each Y is the same divalent alkylene group or a different group; Q is O, S or NR; R is H or alkyl; W is H, alkyl or Z; each Z is the same unsaturated alkyl group or a different group; and each n is 0 or 1.
    [00071] EP1365923B2 describes laser marking of an object that includes a material including a functional group and a metallic or acidic compound that causes an elimination reaction upon irradiation with a laser, to form a contrasting color reaction product. The process comprises directing a laser beam to the areas of the object to be marked. For example, using a carbohydrate and a metal salt, effective marking can be achieved on the coating of a pill or other edible material. It has been conjectured that these compositions can be used at one end of the can.
    [00072] US patent application number US20090117353 Al describes a method for marking a substrate by coating the substrate with a white or discolored solution of a soluble alkali or alkaline earth metal salt of a weak acid, and then irradiating areas of the substrate to be marked in such a way that these areas change color. The substrate typically comprises a polysaccharide material, preferably a cellulosic material such as cellulose, and it has been conjectured that this process may be employed on a metal substrate such as a can end and/or pull tab. As used herein, the claimed step of applying a laser to the coated substrate encompasses the color change described in this paragraph.
    [00073] Preferably, the image produced by the presented process produces a dot with a diameter or other characteristic dimension (such as width, if the laser marking is producing a line) of no more than approximately 50 microns, preferably no more than approximately 30 microns, more preferably not more than about 10 microns, and most preferably about 5 microns. It is understood that a stitch formed in the manner described herein may merge with an adjacent stitch. In this way, the diameter or characteristic dimension of the point can be measured by initial formation or at any other convenient time.
    [00074] The expression "substantially without burning, chemical etching or varnish ablation" does not require loss of matter. It has been conjectured that a slight haze from the application of the laser beam when used in flexible patent applications, in fact, indicates gas emission, loss of volatile matter, or other loss of matter. The present invention encompasses a certain loss of matter during laser application, as long as it does not constitute burning, chemical etching, or ablation as these terms are commonly understood.
    [00075] You are aware of a conventional commercial system for laser engraving of pull tabs that includes a CO2 laser that often operates at around 100W. Each lane of a tab press has its own laser, so that the tab press can operate at about 700 tabs per minute with a laser with a resolution or dimension of approximately 100 microns. Typically, a dark colored varnish is removed by the laser to expose bare aluminum in the form of a simple logo or a few characters. Limiting the process speed is also a limiting the amount of decoration.
    [00076] Laser marking of coatings is employed for flexible and cardboard packaging for various marking applications. Typically, a thermally active pigment is loaded into a clear or light-colored varnish, and a CO2 laser induces a color change. For example, a laser can be applied to a white lacquer label to display black text. Laser marking systems of this type are available from Sun Chemical under the trade name Sunlase and employ a 100 micron YAG laser.
