Abstract (en)
[origin: EP2128041A1] The shell (1) has a blank made of a paper material and comprising an inwardly directed curl (3). The blank is connected in a casing-shape by overlapping (7) two longitudinal edges of the blank. The inwardly directed curl is glued or sealed on an inner side of the outer shell in a region of overlapping. The blank comprises a recess at one of the longitudinal edges in the region of overlapping, so that a region (15) of the curl running parallel to the shell at the overlapping leads to a total thickness that corresponds to three-way material thickness of the blank. An independent claim is also included for a method for manufacturing an outer shell for a double-walled cup.
