A stopper device is disclosed. The stopper device includes a substantially tubular support defining a first axis, and a tab extending along a second axis substantially perpendicular to the first axis. A cap is hinged to the support to pivot between a closed position and an open position. A tamper-proofing band is connected to the cap in its closed position via at least one breakable bridge situated along a third axis in a portion of the tamper-proofing band. The third axis is substantially perpendicular to the first and second axes when the cap is closed. The cap is pivoted from the closed position to the open position by squeezing along the third axis. During a first stage of the squeezing, the at least one breakable bridge is broken, and during a second stage of the squeezing after the first stage, the fastener tab disengages from the cap opening.

1. A stopper device for stopping a neck of a container, said stopper device comprising: a support that is substantially tubular, that defines a first axis, that is suitable for being secured to the neck, and that is provided with a fastener tab extending from the support along a second axis that is substantially perpendicular to the first axis;a cap that has a substantially annular section and that is also hinged to the support to pivot between a closed position and an open position, the fastener tab being suitable for engaging in an opening provided in the cap when said cap is in the closed position; anda tamper-proofing band having a substantially annular section, wherein the tamper-proofing band is carried movably by the support and is connected to the cap in its closed position via at least one breakable bridge, wherein the at least one breakable bridge is situated along a third axis in a portion of the tamper-proofing band, and wherein the third axis is substantially perpendicular to the first axis and the second axis when the cap is in the closed position,wherein the cap is configured to be pivoted for a first time from the closed position to the open position by squeezing laterally along the third axis, wherein during a first stage of the squeezing, the at least one breakable bridge is configured to be broken, and during a second stage of the squeezing after the first stage, the fastener tab is configured to disengage from the opening of the cap. 2. A device according to claim 1, wherein the device is provided with a plurality of bridges that are situated along the third axis in the portion of the tamper-proofing band. 3. A device according to claim 1, wherein the support is provided both with a spout forming the upper portion of the support and also with at least one opening ramp arranged in such a manner that a first end of the ramp that faces towards the spout has a height greater than the height of the opposite second end of the ramp that faces towards the outside of the support. 4. A device according to claim 3, wherein the spout is of cylindrical shape that is centered on the first axis and that has a base that is either circular or egg-shaped with its longer dimension disposed along the second axis. 5. A device according to claim 3, wherein two sets of the at least one breakable bridge are situated on respective sides of the spout that are mutually opposite along the second axis. 6. A device according to claim 1, wherein the device is provided with at least one supporting means that is adapted to guide the tamper-proofing band as it falls, once the at least one breakable bridge has been broken. 7. A device according to claim 6, wherein the supporting means includes a plurality of fins that are uniformly interposed between the tamper-proofing band and the support. 8. A device according to claim 2, wherein the device is provided with engagement means for engaging the fastener tab in the opening of the cap when the cap is moved to its closed position. 9. A device according to claim 8, wherein said engagement means include a first ramp that slopes towards an opening in the spout while going towards the first axis, and that is formed by the upper face of the fastener tab. 10. A device according to claim 9, wherein said engagement means include a second ramp that slopes towards the opening of the spout while going towards the first axis, when the cap is in the closed position, that is formed by an end of the cap, and that is suitable for coming into contact with the fastener tab. 11. A device according to claim 2, wherein the device has retaining means for mechanically retaining the fastener tab in the opening of the cap in the event that the cap is not squeezed sufficiently for it to take up an egg-shaped section, said retaining means including firstly a first slope that slopes towards the spout while going towards the first axis, and that is formed by the lower face of the fastener tab, and secondly a second slope that is complimentary to the first slope and that is formed by the lower edge of the opening of the cap. 12. A device according to claim 1, wherein, in its closed position, the cap closes off the support in leaktight manner, and wherein the support continues to be closed off by the cap in leaktight manner while the cap goes from its closed position to an intermediate position between its closed and its open positions, said intermediate position being taken up by the cap only once the fastener tab is fully disengaged from the opening of the cap.
