A closure assembly for a container filled or fillable with a pourable product comprising at least: - a collar delimiting a pouring outlet configured to allow for the outflow of the pourable product from the container, wherein the collar includes an outer threaded portion; - a lid having a first rim and including an inner threaded portion, wherein the inner threaded portion and the outer threaded portion are configured to allow for fastening the lid to the collar by rotating the lid relative to the collar in a first rotation direction and for loosening the lid from the collar by rotating the lid relative to the collar in a second rotation direction, opposite to the first rotation direction; - a ring member having a second rim facing the first rim; - a first coupling element and a second coupling element angularly distanced from each other and each having a first end (101A, 102A) connected to the lid and a second end (101B, 102B) connected to the ring member; wherein, in each of said first coupling element and second coupling element, the first end (101A, 102A) is positioned downstream of the second end (101B, 102B) along the second rotation direction; characterized in that the closure assembly further comprises - a cutting device configured to rupture a separation membrane sealing a pouring hole provided in the container; - a control device configured to control the cutting device from a rest position to an operative position in which the cutting device is adapted to rupture the separation membrane, wherein the control device comprises control flaps connected to the lid; - a tamper-evidence ring and at least one rupturable coupling bridge designed to rupturably connect and/or rupturably connecting the ring member and the tamper-evidence ring to one another. - a collar delimiting a pouring outlet configured to allow for the outflow of the pourable product from the container, wherein the collar includes an outer threaded portion; - a lid having a first rim and including an inner threaded portion, wherein the inner threaded portion and the outer threaded portion are configured to allow for fastening the lid to the collar by rotating the lid relative to the collar in a first rotation direction and for loosening the lid from the collar by rotating the lid relative to the collar in a second rotation direction, opposite to the first rotation direction; - a ring member having a second rim facing the first rim; - a first coupling element and a second coupling element angularly distanced from each other and each having a first end (101A, 102A) connected to the lid and a second end (101B, 102B) connected to the ring member; wherein, in each of said first coupling element and second coupling element, the first end (101A, 102A) is positioned downstream of the second end (101B, 102B) along the second rotation direction; characterized in that the closure assembly further comprises wherein, in each of said first coupling element and second coupling element, the first end (101A, 102A) is positioned downstream of the second end (101B, 102B) along the second rotation direction; characterized in that the closure assembly further comprises - a cutting device configured to rupture a separation membrane sealing a pouring hole provided in the container; - a control device configured to control the cutting device from a rest position to an operative position in which the cutting device is adapted to rupture the separation membrane, wherein the control device comprises control flaps connected to the lid; - a tamper-evidence ring and at least one rupturable coupling bridge designed to rupturably connect and/or rupturably connecting the ring member and the tamper-evidence ring to one another.
