Definitions

  • the invention relates to a stackable lid for disposable containers, in particular for menu trays made of aluminum foil or the like, with a profiling formed asymmetrically in the lid surface to the center of the lid, with an outer circumferential, almost right-angled, slightly outwardly inclined flap and handle tab strip that are provided on two opposite cover sides, approximately at right angles projecting outwards, with different lengths of handle tab extensions, which are provided with mutually staggered profiles, according to DE-A No. 3146676.
  • the longer handle flap extension is divided into two by a central recess and the shorter handle flap extension extends approximately over the entire straight part of the lid side or only over a central section of the lid side.
  • the design according to the invention allows a three-point holder to be realized by rotating successive lids to be stacked against one another by 180 °, namely by the two lateral parts of the longer handle flap extension (two points) on one side and by holding the handle flap extension in the center (third point). on the other side, so that the lids can be safely removed from the stack individually.
  • the design according to the invention facilitates unstacking by hand, because the individual lids can be easily gripped by the handle bottle extensions.
  • the design according to the invention also enables unstacking with the aid of machines in a simple and safe manner.
  • the drawing shows a lid 2 with a circumferential, upwardly curved edge 4 and an adjoining, downwardly angled flanged edge and handle bottle strip 6.
  • the strip 6 has handle bottle extensions 7, 10 directed outward on two opposite sides of the cover.
  • the lid has a rectangular shape with rounded corners 12, 14, 16 and 18.
  • the handle tab extensions 7, 10 are formed on the short sides of the rectangle 20, 22.
  • the handle tab extensions can also be formed on the longer sides of the rectangle 4, 26 or on all sides.
  • the grip tab extension 7 is longer than the grip tab extension 10; it therefore protrudes further from the strip 6 than the extension 10.
  • the handle tab extension 7 has a central arcuate recess 11 which separates the handle tab extension 7 into two lateral parts 8 and 9.
  • the recess 11 need not be arcuate, it can also be rectangular or triangular, for example.
  • the one-piece handle flap extension 10 is arranged in the center of the side 22 and has a width which corresponds to the maximum width of the recess 11. However, it can also extend over the entire straight part of the side 22 of the cover (shown in broken lines).
  • the depth (maximum) of the recess 11 corresponds approximately to the length of the two parts 8 and 9.
  • the possible connecting web between the two parts 8 and 9 should in any case be narrower than the length of the handle tab 0.
  • the recess 11 can at the same time serve as the beginning of a circumferential tear line provided in the edge region of the lid in a lid crimped on a container by gripping the part 8 or 9 and tearing the lid film outwards in the direction of the lid edge.
  • An asymmetrically arranged profiling 30 is formed on the lid surface 28, in the drawing in the form of a circular decentralized elevation 32, from which eight ribs 34 radiate, which end at the curved edge 4.
  • the radiating ribs 34 are connected to one another by a circumferential elevation 36 that runs parallel and at a distance from the edge 4.
  • the center 38 of the circular elevation 32 lies on the longer center line 40 of the rectangular cover 2, namely at a distance from the center 42 of the cover.
  • the center 38 can also lie on the shorter center line 43 or at any point outside the center 42 of the cover.
  • the elevations are approximately trapezoidal in section (FIG. 2) and are preferably produced using the deep-drawing process.
  • the profiling need not have the uniform shape shown in the drawing, mirror-symmetrical to an axis 44. Any shape is possible.
  • the cross section of the elevations or ribs also need not be trapezoidal; it can also be rectangular or arched.
  • the profiling can also consist of individual elevations distributed over the cover surface. It is only necessary to ensure that these individual elevations are distributed irregularly or are arranged asymmetrically according to a grid with respect to the center or the symmetry axes of the cover.
  • the handle tab extensions can, as shown, also be provided with a profile 46, here in the form of rib-like elevations over the length of the handle tab extensions.
  • the elevations of the two handle flap extensions are offset from one another with respect to the center line 40 of the cover 2.
  • the one-piece handle tab extension 10 preferably has a central bead 48 which additionally stiffens the handle tab extension. As shown, a further bead 50, 52 can be arranged on both sides at a distance from the bead 48.
  • the one-piece handle flap extension 10 can, as shown in FIG. 3, be designed as an arc-shaped flap 54 with lateral flanks 56 and 58 which gradually merge into the edge of the lid. It can also be designed similarly to the handle flap extension 10 according to FIG. 1 (reference number 59), but with lateral flanks 60, 62 gradually transitioning into the edge of the cover. The flanks can also be designed in a straight line with a very slight inclination. The gradual flank transitions increase the rigidity of the tab extension 10.
  • flanks into the edge region of the cover can end, as shown, at a clear distance from the round corners 14 and 16 of the cover.
  • the flanks can also result from the curves, which is shown in dash-dot lines for a flank 64 of the handle flap extension 59.
  • the tab extensions 7 and 10 are designed so that a three-point bracket or support can be implemented for each lid.
  • the three points of the holder are formed by the two parts 8 and 9 of the two-part handle tab 7 and the third point by the one-piece handle tab 10, namely by its central region, which is essentially formed by the central bead 48.
  • the lids formed according to the above description need only be rotated successively in each case with respect to the respectively adjacent lid in order to prevent the lids lying one above the other from jamming. This makes the unstacking much easier.
  • a shorter one-piece handle bottle extension 10 and the two parts 8 and 9 of the longer handle bottle extension 7 lie alternately on the one and opposite side of the lid stack.
  • the shorter one-piece handle tab extensions 10 are then accessible or graspable or fixable in the area of the central recesses 11 of the longer handle tab extensions 7, while the two parts 8 and 9 of these longer handle tab extensions 7 protrude with respect to the shorter handle tab extensions 10 and are laterally accessible or accessible or are fixable.
  • the top lid in each case can be removed, for example, with the aid of at least two suction heads, without the risk that the lid or a plurality of lids underneath can be lifted at the same time.
