Abstract

There is described a spout (4) for opening devices (3) of sealed packages (1) of pourable food products. The spout (4) has an annular flange (7) fixable to a respective package (1), and a tubular neck portion (8) projecting from the flange (7) and defining, with the flange, a through opening (6) through which to pour the food product; and the spout (4) also has, at least at a section crosswise to the axis (A) of the opening (6), a constriction (13) constricting flow of the pourable food product.

Description

technical field [0001] The present invention relates to a spout of an opening device for a sealed package of a pourable food product. Background technique [0002] It is well known that many pourable food products such as juices, UHT (Ultra High Temperature Treated) milk, wine, ketchup, etc. are sold in packages made of sterilized packaging materials. [0003] A typical example of this type of packaging is the parallelepiped-shaped packaging for liquid or pourable food products known as Tetra Brik Aseptic (registered trademark), which is produced by folding and sealing laminated strip packaging materials. [0004] The packaging material has a multi-layer structure generally comprising a base layer for stiffness and strength which may include layers of fibrous material such as paper or mineral-filled polypropylene material; and a plurality of heat-sealed layers such as polyethylene film A layer of plastic that covers both sides of the base layer. [0005] In the case of ase...
