  • the disadvantage of these known containers and packaging is that they are relatively unstable. In particular, in the corner areas of the containers, i.e. in the areas where the side walls of the container meet, instability occurs when pressure is applied, which can ultimately lead to the destruction of the container or packaging.
  • a generic container is used in accordance with the Features of claim 1, a blank according to the features of claim 8 and a packaging according to the features of claim 14.
  • Advantageous embodiments with expedient further developments of the invention are specified in the respective dependent claims, wherein advantageous embodiments of the container are to be regarded as advantageous embodiments of the blank and the packaging and vice versa.
  • a first aspect of the invention relates to a container, in particular for holding a food product, comprising at least one base wall element, a flange element spaced from the base wall element, the flange element surrounding at least one receiving opening.
  • the container has side wall elements connecting the base wall element and the flange element.
  • At least one flange tab is hinged to one of the side wall elements and designed to rest against the flange element.

  • the corner tab comprises a base element hinged to the flange element and an adhesive tab connected to the base element via a bending line.
  • the length of the base element can be selected such that the bending line between the base element and the adhesive tab lies in the area of the base wall element. This ensures that the corner tabs fit into the overall construction of the container without causing the overall construction to warp.
  • the base element it is possible for the base element to have identical or different widths in the direction parallel to the base wall element. This ensures that the base element can be adapted to different designs, in particular different sizes or designs of the side wall elements.
  • the side wall elements each have at least one adhesive tab on their side ends protruding from the base wall element, whereby the adhesive tabs are designed to connect to one another and to a corresponding base element of the corner tab.
  • the design of these adhesive tabs increases the stability of the container as a whole.
  • At least one adhesive tab is hinged to the front of the flange element via a bending line in such a way that the adhesive tab can be connected to an inner side of the respective side wall element.
  • This embodiment also significantly increases the stability of the container, particularly in the area of the front sides of the container.
  • the longitudinal side wall elements in particular each consist of at least two partial wall elements, the partial wall elements being connected to one another via respective bending lines.
  • the containers can be more easily stacked into one another due to this construction.
  • Longitudinal side wall elements are understood to mean the side wall elements that are longer when viewed from above.
  • a second aspect of the invention relates to a blank made of a flat material for producing a container, in particular a container for receiving a food product.
  • the blank comprises a base wall element, a flange element, wherein the flange element surrounds at least one receiving opening, and wherein the base wall element and the flange element are connected to one another via a side wall element.

  • At least one corner tab is hinged to the flange element via at least one fold line in each case, such that the corner tab protrudes into the receiving opening and, when the container is folded,
  • the one-piece design of the cut and the design of the corner tabs result in a simple and cost-effective manufacture of the resulting container and a significant improvement in the stability of the container in question.
  • folding line or "bending line” refer to lines along which corresponding elements of the container can be brought to one another at predetermined angles.
  • Bending lines also refer to folding, creasing or perforation lines or combinations thereof.
  • Folding lines also refer to creasing, bending or perforation lines or combinations thereof.
  • the corner flap comprises a base element hinged to the flange element and an adhesive flap connected to the base element via a bending line.
  • the length of the base element can be dimensioned such that the bending line lies in the area of the base wall element when the container is folded. It is also possible for the base element to have identical or different widths in the direction of the receiving opening.
