Definitions

  • the invention relates to a lid for disposable containers, in particular for menu trays, made of aluminum foil or the like. with a profiling formed in the lid surface and arranged asymmetrically to the lid center, with a circumferential flanged edge strip and with grip tabs, which are also optionally provided with profiling in the form of beads formed between the grip flap end and the flanged edge strip.
  • Stackable lids for disposable containers are known.
  • the lids should also meet another requirement if possible: They should be easy to open without the risk that parts of the contents of the filled disposable container spill out when opened due to sudden unwanted rolling up or tearing.
  • the lid should be able to be removed as completely as possible in one operation. A removal of two Sharing would still be acceptable.
  • the opening poses a particular problem, among other things, because the lid has to seal this disposable container tightly by flanging the circumferential flange edge of the disposable container.
  • a lid handle tabs are provided, through which, among other things. the opening of the closed disposable container is to be facilitated.
  • profiles are formed on these grip tabs, the grip tabs also preferably being of different lengths.
  • the profiles of the gripping tabs located opposite one another are offset from one another in order to improve the ability to unstack them. It has been shown that these grip tabs do not yet guarantee optimal opening of the lid.
  • the object of the present invention is therefore to develop the lid so that it can be easily, defined and removed as completely as possible from the closed disposable container without the risk that parts of the contents of the disposable container accidentally spill or leak when opened.
  • the design according to the invention defines the lid at any point on the peripheral grip tab or along a bead and further below the flare tearable.
  • the inventive design of an incision or a notch on a bead creates a tear-open tab, which tears open along the bead when torn open.
  • the wider flanged edge strips or the additional grip tab strips also create a narrow, downward-facing grip tab on the sides on which no grip tab is provided.
  • the flanging process creates a relatively sharp, circumferential crease line, which means a weakening of the material and thus forms a target tear line along which the lid tears open exactly, relatively easily and in a defined manner without the use of greater forces.
  • the beads and thus the incision or the notch are formed obliquely, as is specified in a further development of the task solution according to the invention in claim 5, there is a more favorable tearing transition from the grip tab via the flanging into the crease line between the flanging and the flap. If the beads of a grip tab are formed obliquely, the beads of the other grip tab of the cover lying opposite need no longer be arranged offset to improve the denesting.
  • incisions or notches can also be provided on these, as stated in claim 6.
  • the incision or the notch is formed along the fold line of a bead, as indicated in claim 7.
  • the design according to the invention according to claims 8 and 9 provides for the cover to be provided with a predetermined tear-open area in the form of a circumferential material weakening in the region of the later flanged edge or the later flare already during manufacture, or the target tear-open area in the form of a circumferential material weakening during the flanging process, i.e. during Closing the container.
  • the tearing process from the grip tab can take place at any peripheral point. Opening a closed disposable container is made considerably easier. Rolling lid parts are no longer available. The risk of splashing part of the contents of the container when opening is practically completely eliminated.
  • the lid designed according to the invention can practically be lifted from the container as a whole flat lid after being torn open all round.
  • the drawing shows a lid 2 with a circumferential, upwardly curved edge 4 and an adjoining, downwardly bent flanged edge strip 6 and an additional circumferential handle flap strip 46.
  • an outwardly directed grip flap extension 8 or 10 is provided on two opposite sides of the cover.
  • the lid has a rectangular shape with rounded corners 12, 14, 16 and 18.
  • the handle flap extensions are formed on the short sides of the rectangle 2 0 , 22; but they can also be formed on the longer sides of the rectangle 24, 26 or on all sides of the rectangle.
  • An asymmetrically arranged profiling 3o is formed on the lid surface 28.
  • the handle tab extensions are, as shown (Fig. 1 and 2), also provided with a profile in the form of beads 32.
  • the beads 32 are, as shown, rib-like elevations and can be, for example, rectangular or trapezoidal in section.
  • the beads can run perpendicular (Fig. 1) or obliquely (Fig. 2) to the sides of the rectangle.
  • the handle flap extensions can have different widths, as shown.
  • An incision 36 or a notch 38 is provided along at least one bead 32, ie preferably along a fold line 34 of this bead. This incision or this notch need not extend over the entire length of the bead, see reference numerals 40 and 42 in FIGS. 1 and 2.
  • This kink line 5o represents a kind of desired tear line. If, for example, the lid 2 is torn open, for example on the handle tab 8, along the incision 36 or 4o or the notch 38 or 42, the lid tears all around relatively easily exactly along the kink line 5o on.
  • the cover 2 can also be torn open along the flanging in a defined manner without providing incisions or notches. The lid can then be lifted off the container as a whole.
  • the transition from the incision 36 or 4o or the notch 38 or 42 to the crease line 5o via the flange 44 is facilitated in that, as shown in FIG. 2, the beads 32 are not perpendicular, but rather obliquely to the cover side or run to the flange 6.
  • the other flap 1o can also be provided with an incision 52 and a notch 54, in order to be able to start the tearing process here again if the tearing along the buckling line 5o does not take place in one operation should go.
  • FIGS. 7-9 show a lid 2, 2 'with a lid surface 4 and a circumferential flanged edge strip 6, 6', 6 "and an adjoining grip flap strip 8.
  • the flanged edge strip 6, 6 ', 6" has at least in part a smaller one Thickness than the rest of the lid.
  • the lid 2 ' is shown in the flanged state on a container 10'.
  • the material-weakened flanged edge strip 6 is flanged around a circumferential flanged edge or circumferential bead 12.
  • the grip tab strip 8 is at the bottom.
  • FIG. 8 shows a special possibility for weakening the flanged edge strip of the cover in a defined manner for the tearing process; the flanged edge strip is given the shape of an inwardly curved bead 6 '(FIG. 8 left) or an outwardly curved bead 6 "(FIG. 8 right) by reshaping, here by embossing. In contrast to the illustration, the bead can also run in an arc shape.
  • the weakening of the material creates a predetermined tear-open area 6, 6 ', 6 "along which the cover 2, 2' struggles los and defined about the circumference of the container 1 0 'is tearable, so that it can be removed practically as a whole lid from the container after tearing.
