Closure device with support ring

A closure device for closing a container,

• wherein the closure device comprises a basic member,
• wherein the basic member provides a channel extending along a closure axis with an inlet opening and a pouring opening axially opposite the inlet opening,
• wherein the pouring opening is arranged in an imaginary pouring plane configured substantially perpendicular to the closure axis,
• wherein the basic member comprises a first guiding means,
• wherein the basic member comprises a fastening means,
• wherein the closure device comprises a closure cap,
• wherein the closure cap has a cap cover and an axially extending cap skirt adjoining the cap cover on a circumferential side,
• wherein the closure cap has a second guiding means,
• wherein the closure cap and the basic member are configured such that
• in a closed state of the closure device, the first guiding means and the second guiding means are in engagement with one another and the closure cap closes the pouring opening, and
• in an open state of the closure device, the first guiding means and the second guiding means are disengaged and the closure cap releases the pouring opening at least in sections,
• wherein the closure device comprises an anchor ring and a connecting device,
• wherein the connecting device connects the anchor ring to the closure cap,
• wherein the anchor ring is in engagement with the fastening means both in the closed state and in the open state of the closure device in such a way that the closure cap is connected to the basic member by the connecting device and the anchor ring even in the open state,
• wherein the basic member has an additional support means,
• wherein the additional support means is arranged axially between the fastening means and the first guiding means,
• wherein the additional support means has a first surface element with a surface normal,
• wherein the surface normal points in the direction of the pouring plane,
• wherein the closure device is configured such that, in the open state of the closure device, the closure cap can be brought into a first position in which the closure cap abuts neither against the first surface element nor against a first edge delimiting the first surface element, and can be brought into a second position in which the closure cap abuts against the first surface element or against the first edge or against the first surface element and the first edge,
• wherein the closure cap is mounted in the second position in a stabilised manner relative to the basic member.
