Definitions

  • the invention relates to a lid for sealing onto a preferably bowl-shaped vessel provided with an edge flange.
  • the invention has for its object to design a lid of the type mentioned so that the food packaged in the container can be heated in the closed state and still there is no danger to the container or the lid by the water vapor generated.
  • the lid is provided at least at one point on its circumference with three cutting lines, one of which introduces both sides of the sealing seam from the bottom facing the vessel and the third at a short distance from the inner bottom from the top and that the lid is off one between its two surfaces and parallel to these fissile material.
  • the cutting lines each extend at least to the middle of the lid material.
  • the lid is made of cardboard and is coated so that it can be sealed on its underside, at least in the area of the sealing seam to be produced.
  • Cardboard material can be split relatively easily, so that the steam valve can be opened easily; however, the sealable coating ensures that the lid is securely closed with the vessel.
  • a tab is formed on the lid in the region of the three cutting lines, which tab projects beyond the edge of the vessel.
  • This protruding flap can be easily grasped and the splitting of the lid can thus be accomplished particularly easily.
  • FIG. 1 denotes a flat lid which is intended for sealing onto a container provided with an edge flange.
  • a flap 2 is formed on this cover 1, on the inner boundary line of which a cutting line 3 is provided from the underside.
  • the cover 1 also has a cutting line 4, which is also introduced from below and is at a distance from the outer edge.
  • a further cutting line 5 runs over the corner of the lid provided with the rag, this third cutting line being introduced into the lid from above.
  • the lid 1 is sealed onto a bowl-shaped vessel 6 which has an edge flange 7 which serves to produce the sealed seam between the lid and the vessel.
  • the tab 2 protrudes over this edge flange 7 and serves as a handle for opening the packaging formed from container and lid.
  • All three cutting lines 3, 4 and 5 protrude slightly further than the middle of the material thickness into the lid 1, so that when tearing open with the aid of the flap 2 a secure material splitting takes place approximately in the middle of the lid material.
  • FIGS. 4 and 5 A lid 1 thus split is shown in FIGS. 4 and 5.
  • the complete rag and the upper half of the lid section delimited by the innermost cutting line 5 are removed, whereby a section of the cutting line 4 is exposed, so that steam arising in the interior of the vessel can escape.
  • a central section of the cover 1 can be cut out along the section line 4, the sealing seam between the cover and the edge flange remaining.
  • Cardboard which is coated with a sealable plastic at least in the area of the sealing seam, has proven particularly useful as the material for the lid. For special filling goods, however, it is advisable to coat the entire inside of the lid with such a plastic.
