Definitions

  • the invention relates to a cover according to the preamble of claim 1.
  • Lids for disposable containers are known.
  • the lids should also meet another requirement if possible: they should be easy to open without the risk of parts of the contents of the filled disposable container splashing when opened.
  • the opening is a special problem because the lid has to seal this disposable container tightly by flanging it on the circumferential flange edge of the disposable container.
  • DE-A 2454645 which shows a lid of the type mentioned at the outset
  • DE-A 2140733 to provide tear-open tabs on the lid, possibly in combination with prepared tear lines
  • torn-open lid parts roll up like a spring due to the inherent tension and in the process splash food parts adhering to them when detached from the container.
  • the removal of the other lid parts still remaining on the container is also very laborious, and there is even a risk of injury to the sharp tear edges.
  • the object of the present invention is therefore to design the lid of the type mentioned at the outset in such a way that it can be removed from the closed disposable container easily, defined and as completely as possible without the risk that parts of the contents of the disposable container accidentally splash or when opened emerge.
  • a circumferential handle tab strip projecting downwards also arises on the sides on which no individual handle tab is provided.
  • a circumferential crease line is formed between the flanging and this tab strip, 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 tearing process can be initiated at any point along the circumferential handle flap extension or along a bead, which can be further improved by providing an incision or a notch on a bead.
  • the beads, the incision or the notch are formed obliquely, there is an even more favorable tearing transition from the grip tab via the flanging into the crease line between the flanging and the grip tab.
  • incisions or notches can also be provided on these.
  • the incision or the notch is preferably formed along the fold line of a bead.
  • the cover blank for a cover can already be provided with a target tear-open area in the form of a circumferential material weakening strip (claims 8 and 9) in the area of the later flanged edge or the later flanging.
  • the invention considerably simplifies the opening of a closed disposable container. Rolling lid parts can no longer arise. The risk of splashing parts of the contents of the container when opening is practically completely eliminated.
  • the lid designed in accordance with the invention can be lifted effortlessly as a whole flat lid from the container after being torn open all around.
  • the drawing shows a cover 2 with a circumferential, upwardly curved edge 4 and an adjoining, downwardly bent flanged edge strip 6 and an additional circumferential grip flap strip 46.
  • An outwardly directed grip flap 8 or 10 is provided on two opposite cover sides.
  • the lid has a rectangular shape with rounded corners 12, 14, 16 and 18.
  • the handle straps are formed on the short sides of the rectangle 20, 22; but you can also choose the length Ren rectangular sides 24, 26 or be formed on all rectangular sides.
  • An asymmetrically arranged profiling 30 is formed on the lid surface 28.
  • the handle straps 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 grip tabs can have different widths.
  • an incision 36 or a notch 38 is preferably provided along a fold line 34 of this sikke.
  • This incision or this notch need not extend over the entire length of the sikke, see reference numerals 40 and 42 in FIGS. 1 and 2.
  • the flaring process creates a relatively sharp crease line 50 between the flare 44 and the strip 46 or the tab 48, which is formed all around underneath the flare 44.
  • This kink line 50 represents a kind of predetermined tear line. If, for example, the cover 2 is torn open, for example on the grip tab 8, along the incision 36 or 40 or the notch 38 or 42, the cover tears open relatively easily exactly along the kink line 50 all around.
  • 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 40 or the notch 38 or 42 to the crease line 50 via the flange 44 is facilitated by the fact 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 tab 10 can also be provided with an incision 52 and a notch 54, in order, if necessary, to be able to start the tearing process again here, if the tearing along the crease line 50 does not take place in one operation should go.
  • FIGS. 7-9 show a cover 2, 2 'with a lid surface 4 and a circumferential flanged edge strip 6, 6', 6 "and an adjoining flap tab 46.
  • the flanged edge strip 6, 6 ', 6" has a smaller one, at least in parts Thickness than the rest of the lid.
  • the cover 21 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 46 is at the bottom.
  • FIG. 8 shows a special possibility of 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, in this case by embossing.
  • the bead may also run in an arched manner, as shown.
  • the weakening of the material creates a desired tear-open area 6 ', 6 ", along which the lid 2, 21 can be torn open effortlessly and in a defined manner approximately at the circumference of the container 10', so that it can be removed from the container practically as a whole lid after the tear-open.
