  • the sealing ribs 41 consist of the container material and are integrally formed.
  • the container upper edge 40 is here surrounded by a radially outside arranged, circumferential and downwardly projecting web 43 which fits tightly against the radially outwardly projecting circumferential ribs 9 of the container.
  • the groove bottom forming horizontal cover portion 44 extends radially outwardly beyond the web 43, so that the Abgleitschräge 17 is made steeper than in the previous embodiments. Between web 43 and sliding bevel 17 stiffening ribs 45 may be provided.
  • substantially vertical stiffening ribs 46 are provided on the projections 29 provided on the inner side of the lid, which are connected to the outer, substantially vertical and substantially horizontal region of the projecting segments 29 and terminate in front of the circumferential sealing edge 20.
  • the stiffening ribs may also be pulled forward to the sealing edge 20, but preferably they do not rest linearly against the sealing edge in order to avoid sealing errors due to shrinkage, in particular not at the level of the sealing abutment region of the sealing rib on the container inner wall, or with a vertical region, whose vertical extent is significantly smaller than the vertical extent of the reinforcing rib at the level of the inner edge of the projection.
  • the stiffening ribs 45 formed in this way can correspondingly also be located on an inner side be provided circumferential edge of the lid, which is not broken down into protruding and recessed areas.
  • the inner cover area 49 is arranged below the lower edge of the sealing rib, wherein the stiffening ribs 46 preferably at the level of the inner lid or below the lower edge of the sealing rib 20 on the inner wall of the projections or the peripheral edge, without being limited thereto.
  • the stiffening ribs 45 can simultaneously serve as support on the cover located underneath and in this case lie linearly or else punctiform on the upper side of the inner protrusions 29 or peripheral edges.
  • the lid is supported on the underlying lid with the below the locking edge down under projecting web 47 on the surrounding, the Abgleitschräge 17 surrounding bead 48 from.
  • the sealing rib 20 is hereby spaced from the adjacent lid, they may possibly also be supported on this.
  • FIG. 9 shows a further embodiment of a container, which represents a modification of the container according to FIG.
  • the difference to the cover of Figure 1 is the arrangement of the reinforcing rib 16, which is here arranged directly on the container outer wall 3.
  • the patch lid is located laterally on the outside of the reinforcing rib 16 with its inside.
  • the reinforcing rib has approximately the strength of the container wall.
  • the reinforcing rib 16 protrudes radially up to the radial outer surface of the ribs 9.
  • the embodiment of the container of Figure 1 is particularly advantageous because there the Reinforcing rib stabilized the peripheral edge 5 and cooperates particularly vorteihaft with the effective range of the container wall with the circumferential rib 20.
