Abrégé

The invention relates to a thermoformed lid 4 and a packing container for food, the former comprising a container lower part 1, which has a container base 2 and a container wall 3 that surrounds a receiving area of the packing container made of plastic, and comprising a container lid 4, which is to be arranged on the container wall 3 so as to close the receiving area 5. The container lid 4 has a lid base 6 and a circumferential lid wall 7 which is inclined relative to the lid base 6. A latching or snapping element 8, 28 is formed on the lid edge face pointing towards the lid center for releasably latching to the upper edge 9 of the container wall 3 and for holding the container lid 4 on the container wall of the lower part 1 as the container 1.

Abrégé

The invention relates to a process for producing thermoformed articles such as food packagings or parts thereof with a mechanical weakening between adjoining functional areas, which, for utilization by a user, can be at least partly separated at the mechanical weakening, in a thermoforming die having an upper die and a lower die, the mechanical weakening being introduced with a three-dimensional extension during the period of time during which the material to be formed is located in the thermoforming die, and a thermoforming die for implementing the process.

Abrégé

The invention relates to methods for producing a thermoformed item, in particular a packaging item, such as a container or a container lid, and to a thermoformed item, in particular a packaging item, such as a container or a container lid. At least one threaded segment or lug segment protruding in the radial direction is formed on such an item in order to provide a thread-like or bayonet-coupling-like structure and thus a capability of closing the item.

Abrégé

The invention relates to a method for the production of thermoformed articles (38), such as food packaging or parts thereof, with a mechanical weakening (34) between mutually adjoining function areas, which can be separated at least partly from one another at the mechanical weakening (34) for utilization by the user, in a thermoforming die with an upper and a lower die. The mechanical weakening is introduced during the period, in which the material, which is to be shaped, is present in the thermoforming die, by a three-dimensional extension. Furthermore, the invention relates to a thermoforming die for implementing the method.

Abrégé

The invention relates to a method for the production of lids (1) made of a foil material, for cups for storing liquids, wherein the film web (2) is fed into a first forming station (I). A shape (3) of a finished lid is formed in the film web by plastic thermoforming. The film web (2) with the lid shapes embossed in said web is then incrementally fed to further processing stations (II to IV). A plurality of lid shapes (3) may be deep drawn or embossed in a larger group and may be processed in groups by the plurality of stations, before they are separated into groups.
