Definitions

  • the invention relates to a deep-drawn tray, in particular an aluminum tray, having a rolled edge corresponding substantially to EP 2 334 564 and the preamble of claim 1 .
  • the cited document discloses the production of a tray made of aluminum, in particular for food or beverage ingredients but also for animal food, with a rolled edge in which the inside and outside are colored differently, on the one hand to allow for a visually appealing appearance after sealing a plate onto it, on the other hand to provide, by appropriate combination of the interior color and the exterior color, wherein the former is also visible on the roll edge from the outside, to the user joy and/or information about the contents of the still closed shell or other information by means of the visually pleasing impression.
  • sealable lacquer on an aluminum tray is also disclosed in DE 690 28 628 T2, the translation of EP 468 079.
  • this is done by the features specified in the characterizing part of claim 1 , in other words, that during imprinting of the tray which on its bottom surface, the outer surface, receives an imprint of information and/or a decorative motif, in the area of its rolled edge is provided on the later inside and/or the later outside with a colored lacquer overprint, which optionally also extends into the region of the sealing face and/or the sealing surface opposite to the outer surface.
  • the aluminum trays for the intended use are imprinted on the outside prior to the deep draw process and, either during printing or independently of printing prior to printing, markers which can be of various types, which effect the placement of the deep draw tool and of the stamping tool, are applied to the web. Therefore, during the printing process, it will pose not problem to apply, precisely matching these markings on the desired side of the continuous material, be it the later inside and/or the later outside, printing material exclusively in the area of the later rolled edge, optionally also extending into the region of the sealing face and/or the sealing surface opposite to the outer surface. Since this is a printing process, preferably a gravure printing process, it is easily possible to apply various colors, which thus enable correct color coding or visually appealing running colors (rainbow, etc.).
  • the accuracy of the color application is to be kept, without much adjustment, in such close geometric tolerances that, if so desired, the actual sealing face of the plate which lies within the rolled edge and/or the surface opposite to this area may be kept free of the lacquer application, so that any sealing properties of the lacquer would in this case not need to be considered.
  • the user may continue to be assured of the appearance of the interior of the tray familiar to and appreciated by him, especially when the tray comes in contact with the food, the animal food, or the beverage additives, and the consumer's negative assessments known from the prior art have no basis.
  • FIG. 1 shows a perspective top view of the underside of an “upside down” tray according to the invention
  • FIG. 2 shows a top view of the empty tray in a perspective view from a viewpoint similar to that of FIG. 1 ;
  • FIG. 3 shows a section in the region of the rolled edge in a purely schematic fashion and highly magnifies
  • FIG. 4 shows a variant of the minor figure of FIG. 1 with indicated multi-colored coding
  • FIG. 5 shows a view in accordance with FIG. 2 with an additional lacquer application on the sealing face.
  • FIG. 1 Shown in FIG. 1 is an example of a deep-drawn aluminum tray 1 usually with an imprint on the bottom and optionally on the slanted side walls 3 , as well as on the stiffening ribs within side wall 3 and on the colored rolled edge 4 , the imprints for the most part not shown in the figure.
  • Coloring 5 is indicated by the dots only in the minor character depicted in a larger scale.
  • tray 1 may be uncolored aluminum, it may be a lacquer or plastic coating, optionally mostly yellow or golden, or any other design desired by the manufacturer, the filler, or the consumer. It is vital and evidently shown in the figure that the rolled portion of the rolled edge 4 on the inside 2 of the aluminum foil from which the tray was deep-drawn is colored, so that the color becomes visible from the outside during rolling, both from below ( FIG. 1 ) as well as seen from above ( FIG. 2 ).
  • the rolled edge is shown “neutral” in FIG. 3 , because while in most cases it is rolled in such a manner that the inside of the foil is rolled outwards, there are also applications in which the outside is rolled inward. Most of time, the roll is situated completely or substantially below or above the sealing face 6 , and rarely, as shown, in a centered manner. Through this neutral depiction, FIG. 3 is intended to indicate all these possibilities. Depending on the intended rolling direction, the ink application should be carried out on the “right” side, which is not a problem with the commonly available printing presses.
  • FIG. 2 shows the variant in which the coloring covers only the area of the rolled edge but not, or hardly, the shoulder 6 of the tray on which the sealing with the plate (not shown) takes place. Since in almost all applications the inside of an aluminum tray is coated with a sealable plastic layer, such as to preserve the content from direct contact with the aluminum, this solution still provides the entire or almost entire shoulder surface extending in form of a ring around the opening of the tray for sealing with the plate.
  • FIG. 5 shows a variant in which the lacquer also covers the sealing face 6 ; it may either be itself sealable or shine through from under the then preferred transparent sealing layer.
  • the variant in which the opposite surface 7 ( FIG. 1 ) facing sealing face 6 is imprinted is not shown.
  • paint or “lacquer” is to be understood in the broadest sense and includes all materials that can be applied by a printing process.
  • the change in color, brightness, intensity along the roll edge may be due to purely aesthetic reasons but may also encode information as is known mutatis mutandis from the bar code and other identification features.
  • Markers may be printed onto the continuous material; they may also consist of imprints of continuous material, and they may consist of “multiple parts” per later tray, for example, to specify the correct angular position in respect to the deep draw mold and the like, as provided for in the prior art.
