Apparatus and method for injection molding opening devices on sheet packaging material for packaging pourable food products

An opening device for a sealed package containing a pourable food product and having at least one removable portion includes a frame defining a pour opening and having a fastening portion fixable to the package about the removable portion. A cap is adapted to be fitted to the frame to close the pour opening and is removable from the pour opening to permit pour-out of the food product. An anchoring portion which engages the pour opening is fixable directly to the removable portion, and is removable from the pour opening to at least partly detach the removable portion from the package. The anchoring portion is connected integrally to the frame by a breakable connecting mechanism, and is connected to the cap so as to move together with the cap when removing the cap from the pour opening.
