OPENING ARRANGEMENT FOR PACKAGES

摘要

The invention relates to an opening arrangement for a package of the type which comprises a double-walled triangular lug (15) communicating with the interior of the package and being connected to one lateral edge (14) of the package and which comprises a sealing fin (10) extending over the top side (11) of the package and the said triangular lug (15). On both sides of the base line of the sealing fin (10) parallel tearing perforation lines (6) located opposite one another are provided which at a point on the top side of the triangular lug (15) converge uniformly in an arc-shaped manner so as to extend over the lateral edges (13) of the triangular lug (15) and converging on the underside of the triangular lug (15) without the said tearing perforation (6,6') having any breaks or point of discontinuity other than those arising in connection with the perforation (6') passing over the lateral edge (13) of the triangular lug (15).
