  • the fillet can extend up to 180 ° at the transition between cover collar and cover plate.
  • the cover collar is formed in the direction of the open side of the lid to the bead following up to its lower edge in the form of a truncated cone.
  • Such a design of the cover collar facilitates the sliding of the lid on the upper edge of a container to be closed and ensures, for example, a self-centering of the lid when pushed. Also, the stackability of the lid is much easier by such a design of the cover collar.
  • a section of the reinforcing ring arranged above the cover bottom has an outer diameter which is smaller than an inner diameter of the cover collar below the bead, and an inner diameter of the bead is smaller than the outer diameter of the reinforcing ring above the cover bottom.
  • the bead extends radially outward relative to a section of the cover collar which is directly adjacent to the cover plate.
  • the bead can receive a mouth roll of a container to be closed and thereby ensure a secure locking of the lid on the container.
  • the reinforcing ring is provided on an upper side of the lid base with a rolling ring extending over the circumference of the lid with a substantially circular cross-section.
  • Such a rolling ring serves to stiffen the lid, wherein the rolling ring can rest on the cover plate in order to increase the reinforcing effect.
  • the rolling ring can also serve as a support surface when stacking several cups.
  • the rolling ring rests on the upper side of the lid bottom.
  • the reinforcing ring is provided on an upper side of the lid base with a peripheral frame.
  • Such a frame serves to stiffen the lid and may be cylindrical or tapered upwards in the form of a truncated cone. As frame a 180 ° turned over and verpresster edge is called. Such a frame allows a very rigid construction of the multi-part lid according to the invention.
  • the frame is cylindrical.
  • the frame is frustoconical.
  • a frusto-conical, upwardly tapering design of the frame facilitates the stackability of multiple covers.
  • the reinforcing ring lies flat against a circumference of the cover collar.
  • a flat contact of the reinforcing ring on a circumference of the cover collar ensures a secure connection and a very stable design of the lid according to the invention.
  • the reinforcing ring has a radially outwardly extending bead, the radially outer
  • Top serves as a support surface for stacking another similar lid.
  • a lower, peripheral edge of the cover collar and / or the reinforcing ring is in the stacked state of two similar cover on the support surface at the top of the bead.
  • the reinforcing ring above and below the circumferentially circumferential bead is connected to the cover collar by gluing or sealing.
  • the lid according to the invention can be made particularly stable and thus be made for example of thinner paper material.
  • the presentation of the Fig. 1 shows a multi-part paper lid 10 having a base body 12 and a reinforcing ring 14 which surrounds the base body 12.
  • the lid 10 is placed on a cup 16.
  • the base body 12 is made of a one-piece paper blank and has a cover plate 18 and a circumferential cover collar 20 extending from the cover plate 18.
