Definitions

  • the invention relates to a container with a crimp closure, consisting of a lower part, in particular a menu bowl, with a bottom, adjoining side walls and an outer peripheral flange running around the upper edge thereof, and a lid as an upper part consisting of film material in the form of a rectangular Foil blank, the four corners of which are folded over to form folding tabs on the upper side of fold lines that run obliquely to the edges of the foil blank, and whose sides, when placed on the lower part, parallel to the edge flange, are flanged on all sides around the edge flange and pressed together with the same.
  • Such a container is described and shown in DE-OS-3 100 761. Characterized in that the four corners of the lid are folded over on its top and thus form pull-tabs, the lid can be detached from the lower part of the container designed as a menu tray in such a way that contamination from dripping food residues or liquid splashing due to difficult opening is not to be feared .
  • the well-known menu bowl has a rounded edge flange at the corners, which limits the size of the pull tabs. If, in fact, a film blank of normal size is used, which protrudes by about an edge flange width beyond the outer dimensions of the edge flange on all four sides before flanging, relatively small pull tabs result due to the relatively small corner radius, which are difficult to grasp with the fingers. In addition, when the flange is opened in the corner area by pulling the tab over the relatively small corner radius of the edge flange, there is locally highly uneven loading of the pull tab, which often has the consequence that the tabs tear and tear due to excessive stress.
  • the subject of DE-OS-3 018 876 is a lid made of film material for all-round crimping with a peripheral edge flange of a menu tray which is also rounded at the corners.
  • the right-angled film cut is first folded with the four corners around fold lines on its upper side which run obliquely to the edges of the film cut.
  • the resulting grip tabs on the two opposite sides are then folded onto the top, whereupon the edge area is angled downwards to form rounded corners.
  • the production of such a cover requires a larger number of individual steps for the formation of the grip tongues, which is why the device required for this is relatively complex.
  • more handles are required to open the container than with the container according to the aforementioned DE-OS-3 100 761.
  • the two handle tongues provided on the opposite sides of the container require additional material expenditure, which is required for the series production of the menu trays with a lid has a significant impact in large numbers.
  • DE-PS-1 586 221 is a method for closing filled menu trays and the like with foil lids to form tear tabs.
  • the manufacturing process explained there is relatively complex and requires a considerable amount of material to form the tear tabs.
  • cover closures for menu trays and the like are known in practice, in which a tip formation is provided as a pull-on tab below the edge flange in the corner region. This area is not visible when the menu tray is filled with the user, so that he has to try to grasp the tip by pressing below the edge flange in order to be able to open and pull off the lid. Due to the not completely drip-tight closure, fingers are often soiled by escaping, in particular liquid, food.
  • the invention has for its object to improve the container of the type outlined at the outset so that a user-friendly opening possibility is possible without damaging or destroying the lid with the smallest possible film cut for the lid.
  • edge flange of the lower part of the container has chamfered corners which run essentially parallel to the fold lines.
  • the invention allows a comparatively inexpensive production with a simple device for containers with a crimp closure.
  • DE-AS-1 807 305 describes Plastic container in the form of regular polygons, each with a circumferential edge flange of constant width, onto each of which a lid of such a size and shape and in such an arrangement is sealed to the container that the corner regions of the lid protrude at least four flange edges, so that four tear-open tabs are formed are achieved and according to the task that replacement tabs are available for opening the container if a tear-open tab is damaged.
  • the lid is square with a side length equal to the distance between two opposite flange edge sides and is arranged in such a way that its square regions protrude on four mutually opposite flange edge sides.
  • the sealing closure is completely tight and requires considerably greater opening forces.
  • the corner areas of the sealed lid protruding from the edge flange can easily be damaged or even torn off on the way to the consumer.
  • they are bent downwards, the consumer can only attempt to grasp them by pressing buttons below the edge flange, in contrast to the crimp closure according to the invention, in which the pull tabs are arranged in a clearly visible and protected manner on the top side of the lid.
  • the seal can only be opened by holding the container and pulling a pull-up tab upwards in the diagonal direction of the container, while in the flare lock according to the invention two diagonally opposite pull-tabs are pulled outwards at the same time and then downwards and then upwards along the longitudinal edges of the container to then do the same with the other two corner pull tabs.
  • the lid edges flanged under the edge flange detach from the edge flange, starting from the corners at whose pull tabs are pulled. Overall, the crimp closure according to the invention is much easier to open and with less risk of contamination than the known seal closure.
  • the lower container part can have bevels in the other corner areas as well as on its edge flange.
  • Such bevels can be limited, for example, to the upper edge of the side wall of the lower container part, but can also extend over their entire height to the bottom.
  • FIG. 1 shows a right-angled, cut-to-size film cut 10 made of aluminum, from which the lid for closing a lower container part 12 made of aluminum, for example a menu tray, is to be produced.
  • the four corners 14 are folded over fold lines 16 onto the top of the film blank 10, which run obliquely to the edges 18 of the film blank 10, preferably forming an angle of 135 ° with them. In this way, there are 14 pull tabs 20 at the four corners.
  • FIGS. 2 and 4 show that the menu shell 12 has an edge flange 22 which runs around the top, the corners 24 of which are chamfered and run parallel to the fold lines 16.
  • the edge region 26 of the lid 28 shown in FIG. 2 is angled downward, as a result of which the lid 28 is ready for use to close the menu tray 12.
  • FIGS. 3 and 4 show the fastening of the cover 28 to the menu tray 12, around the edge flange 22 of which the edge region 26 of the cover 28 is flanged.
  • arrows A indicate the loosening of two diagonally opposite pull tabs 20 and arrows B indicate the subsequent loosening of the other two pull tabs 20.
  • the pull tabs 20 are first pulled outward in the container plane and then downward until the entire edge region 26 of the cover 28, which is flanged under the edge flange 22, gradually releases. Then, as shown in FIG. 8, the cover 28 can be lifted upwards in a non-destructive and effortless manner.
  • the container remains in place throughout the entire opening process. Due to the lifting of the lid 28 above the menu tray 12, residues of filling material adhering to the underside of the lid 28 only drip back into the menu tray 12 and thus do not contaminate the dining area.
