Definitions

  • This invention relates generally to the subject of containers, for example metal or plastic containers for consumer products such as food and beverages. More particularly, the invention relates to cans and can ends having a manually manipulable tab used for opening such a container that contains a promotional or decorative image.
  • Figure 1 is a perspective view of a conventional prior art beverage can 10.
  • the can 10 is formed from a one-piece drawn and ironed cup. The cup walls are stretched in a can body making station to form the side wall 12 of the can.
  • a neck 14 is formed on the upper portion of the can by a set of necking stations, such as described in the patent to Caleffi et al., U.S. No. 4,774,839 or Tung et al., U.S. No. 5,755,130.
  • the can is sent to a flanging station where a flange is formed around the upper peripheral edge of the can.
  • the flange is seamed to the peripheral edge of a can end 18 after the can is filled, in accordance with well-known techniques.
  • the can end 18 includes a generally flat center panel 19, integrally connected to a circumferential countersink which is surrounded by a peripheral flange or curl.
  • the center panel includes score lines which defines a panel, which when opened, allows the contents of the can to be removed.
  • the scored portion 20 cooperates with a manually manipulable tab 22 so as to enable the user to either remove, for example, most of the center panel, such as in a full panel easy open end that is used for cans containing cat food, snacks or other foods, or to remove or open the pour panel of a beverage can.
  • the score 20 defines a pour panel 21 which, after opening, remains attached to the center panel by a hinge (not shown).
  • the pour panel is opened by the tab 22.
  • Tab 22 is secured to the center panel 19 by a rivet 32.
  • the user inserts a finger underneath the tab 22 and lifts the tab up, causing the rivet 32 to pull up, which initiates the pop or initial fracture of the score line 20. Further lifting of the tab 22 further propagates the severing of the score to complete the opening of the can. At that point the user may pour the contents out of the can or drink from the can.
  • Patent 3,822,496 shows a can with a detachable display plate or button that is affixed to a pull-ring of a can. Additionally, beverage cans have been previously sold in the United States with alpha-numeric characters formed on the tab with ink-jet printing.
  • Published PCT application PCT/GB00/00463, publication no. WO 00/47487 published August 17, 2000 discloses methods and apparatus for printing on tabs and various features for promotional containers and container ends.
  • EP-A-1,123,772 discloses a laser apparatus which provides markings on a tab surface.
  • An end for a can such as a can containing food or beverages for human consumption, is provided that includes a scored portion forming a frangible portion in the end.
  • a manually manipulable tab secured to the end is provided and has a first end portion and a second end portion and first and second opposite sides. The first end portion cooperates with the scored portion to open the end when the second end portion is lifted up with the user's finger or other implement.
  • the tab further comprises a tab surface extending across the tab between the first and second sides.
  • the tab surface is distinctively decorated, as by forming a promotional or decorative image in the tab.
  • the promotional image is formed as a combination of a void in the tab and laser etching of the tab surface in the region adjacent to the void.
  • the tab is colored and laser etching bums the color off the tab to reveal the base color of the tab material.
  • the promotion image is formed by applying a layer of a color agent to the tab surface (such as by applying a lacquer containing a color agent to the tab), feeding the tab material to a laser station where a portion of the color agent is burned off revealing the silver aluminum color below the color agent, then feeding the tab into a press where the tab features are formed.
  • the press includes a stamping tool that forms the void forming part of the promotional or decorative image.
  • the end in accordance with the invention can be provided for any suitable can, for example a can for containing a human or animal food product.
  • the can comprises an aluminum beverage can, but cans for snack foods (e.g., peanuts), or other types of products can be used with the inventive ends and tab.
  • the end may be a full panel easy open end, in which full panel is removed, or an end in which the tab is used to open a pour panel in the end to provide a means of access to the contents of the can.
  • the promotional or decorative image may be a logo or trademark of the manufacturer of the contents of the can, or other a promotional or fanciful image associated with the manufacturer of the contents of the can.
  • Other examples of promotional images would be letters, numbers, symbols, or fanciful shapes.
  • Figures 3 is a plan view of an inventive end 18 for the can 10 of Figure 1.
  • the end 18 has a scored portion 20 for defining an opening in the end, and a manually manipulable tab 22 having the promotional or decorative image 30 formed therein.
  • the tab 22 is secured to the end 18 by a rivet 32 or other suitable structure that allows the tab 22 to remain fixed to the end 18 when the tab is manipulated by the user to open the can 10.
  • the tab 22 has a first end portion 34 and a second end portion 36 and first and second opposite sides 38 and 40, respectively.
  • the first end portion 34 is forced into the region 37 bounded by the scored portion 20 to open the end when the second end portion 36 is lifted up with the user's finger or other implement.
  • the tab further comprises a tab surface 41 extending across the tab 22 between the first and second sides 38 and 40.
  • the tab surface 41 has a promotional or decorative image 30 formed therein.
  • the tab is coated with a lacquer or other pigment to form a colored tab (e.g., black, red or blue), and the promotional image 30 is formed by forming a void 50 in the tab and laser etching of the color adjacent the void in a predetermined pattern or arrangement 52 to reveal the base metal (aluminum).
  • the combination of the void 50, which reveals the color of the end panel 19 (which may be colored, e.g., gold, or uncolored, i.e., silver), plus color tab surface 41, plus laser etching at 52 forms a distinctive container end.
  • the color of the end panel 19 which would also be viewed through the void 50 in the tab
  • the color applied to the tab surface 41 and the color of the base tab material (silver for an aluminum tab) in the region 52 where the laser has burned off the color.
  • the particular image shown in Figure 3 is a promotional or decorative image in the shape of the star.
  • the star has a circular punched hole 50 and the points 52 of the star consist of areas where the laser has burned off the color or coating applied to the tab surface.
  • the void 50 reveals the gold color
  • the silver points 52 against the black tab background in the tab surface 41 forms a highly distinctive arrangement.
  • the resulting star presents no sharp surfaces to the user which could possible injure the user when the can is opened.
  • the combination of void feature and laser etching opens many new possibilities for decoration of tabs for cans.
  • Figure 4 shows a decorative image in the form of the letter "1" with the bar 50 formed as a void and the base and upper left hand portions of the number formed as laser etchings of the tab surface to burn off color that is applied to the tab.
  • the tab has no color and the laser etching bums off the coating to the aluminum base stock, which may result in a darkening of the tab color in the area 52.
  • the promotional or decorative image consists of the letter "P" and is formed from a void 50 and a laser etching in region 52. The laser etching and void could be reversed in the examples of Figures 4 and 5, of course.
  • Various types of promotional or decorative images 30 may be formed in the tab surface, such as logos, sports team logos, trademarks, an image of a product or feature suggesting the contents of the can, letters, numbers, symbols of various kinds, arbitrary designs, and so on.
  • the promotional image 30 is formed in the tab 22 by first applying a layer of a color agent or lacquer containing a color agent to the tab surface, or by buying pre-coated tab stock, and then removing a portion of the color agent in predetermined locations using a laser.
  • the tab stock is then introduced into a tab forming press (such as a press from Dayton Reliable Tool).
  • the tab is then formed in the press.
  • One of the operations of the press includes a stamping operation wherein the void 50 is stamped out of the tab surface.
  • the void will normally be formed immediately adjacent to where the color etching has occurred, so that the laser etching and the void together form a single unitary image.
  • a logo in the shape of a bull's head.
  • the laser etching is performed to etch out the shape of the horns, ears and nose of the bull, revealing these features in the base material color.
  • the remainder of the tab surface is colored tab material.
  • An inverted triangle is stamped from the tab surface to form the basic head shape.
  • the laser etching of the tab surface 41 in region 52 could be performed after the tabs have been formed and affixed to the end in a shell conversion press. With this embodiment, precise positioning of the end relative to the laser would have to be maintained in order to insure that the etching is performed at the correct locations.
  • Still further embodiments would introduce three-dimensional shapes to the tab from embossing or debossing, in addition to the etching and void forming features described herein.
  • the metal in the tab surface 41 is either pressed down (towards the end panel 19) or raised.
  • the techniques of the invention can be applied to various types of ends for containers, and representative examples include ends for can for food, beverage and other types of products.
  • Figure 3A is an alternative arrangement of the embodiment of Figure 3, in which the laser etching is applied to trace a circular outline 52A and the outline 52B of the points of the star feature, showing the color of the panel 19 showing through the void 50.
