Abstract
A reclosable opening device for a sealed package of a pourable food product includes a frame fitted about a pierceable portion of the package and defining a through pour opening; a removable threaded cap that screws onto the frame to close the pour opening; a tubular cutter engaging the pour opening and having a cutting device which cooperates with the pierceable portion to unseal the package; a first connector connecting the cap to the cutter, and which, as the cap is unscrewed, pushes the cutter towards the pierceable portion and a second connector connecting the frame to the cutter, and which, in use, feed the cutter along a predetermined piercing path through the pierceable portion in response to unscrewing of the cap; and the piercing path, as the cap is unscrewed, has a first portion of pure axial translation, followed by a second portion of both axial and rotary motion.
