Abstract
A closure, particularly for use on liquid-packing containers, comprising a first substantially circular portion from the periphery of which a second substantially cylindrical portion projects substantially orthogonal to the first portion, the closure comprising a sealing system provided with a first sealing element associated with the first portion and second and third sealing elements associated with the second portion, the first, second and third sealing elements cooperating with the packing container. The first and the third sealing elements provide sealing by deformation when the closure is applied to the container. The second sealing element provides sealing by direct compression when the closure is applied to the container.
