Definitions

• the present invention relates to a closure assembly according to the preamble of the independent claims.
• the assembly comprises a closure spout and a closure cap.
• the closure spot is adapted to be fitted to the neck of a container and comprises a dispensing opening.
• the closure cap comprises an upper wall and a skirt de ⁇ pending therefrom, adapted to be fitted to the closure spout to close the container, especially for use on pressurized contain ⁇ ers such as carbonated beverage containers .
• Sport caps differ from the more traditional so-called single caps in that they are adapted to provide a dispensing outlet for directly drinking off. Generally they have two areas of sealing: i) between the closure and the container neck (similar as single caps have); and ii) between two or more parts of the closure.
• the two parts of the closure may include, for example, a spout with an outlet or dispensing opening adapted to be used for directly drinking off.
• Such sports caps permit people to have their beverages in an "on the go drinking" and especially an athlete, particularly a cyclist, to drink during sports activity.
• the threads comprise a single, substantially continuous thread portion on the container neck with a low thread pitch angle, typically less than 50°.
• the low pitch angle is needed in order to ensure that the closure does not unscrew spontaneously under pressure from inside the con ⁇ tainer.
• the low pitch of the helical threads also means that the closure typically needs to be rotated through more than 360° to disengage it completely from the container neck.
• EP0868358 proposes a neck and a single-cap closure which are constructed and arranged to provide a vent for venting gas from the container neck at least when the closure is in an intermedi ⁇ ate position.
• the closure comprises means for blocking or re ⁇ stricting rotation beyond the intermediate position when there is an axial pressure in a direction emerging from the container neck. These means are part of the screw thread as well of the container neck as of the closure.
• the invention provides a closure assembly compris ⁇ ing a closure spout adapted to be fitted to the neck of a con ⁇ tainer and a closure cap adapted to be fitted to the closure spout to close the container.
• the closure spout comprises a dis ⁇ pensing opening.
• closure spout has narrowed cylindrical neck with a smooth and slightly rounded lip to permit drinking directly from the container.
• the closure cap comprises an upper wall and a skirt depending therefrom.
• the closure cap has a first retaining arrangement comprising one or more elongate first retaining segments. Each first retaining segment has upper and lower first retaining surfaces.
• upper means directed away from the container when the assembly is applied to the container and “lower” means directed towards the container when the assembly is applied to the container.
• the closure spout has at least one substantially continuous sec ⁇ ond retaining arrangement comprising one ore more elongate sec ⁇ ond retaining segments.
• Each second retaining segment also has upper and lower second retaining surfaces.
• the lower second retaining surface has no pitch or at least a relatively lower pitch in a first region, a relatively higher pitch in a second region displaced from the first region in an unscrewing direction and no pitch or at least a relatively lower pitch in a third region displaced from said second region in a unscrewing direction.
• the present invention shall be understood as also implying a closure assembly wherein the first retaining arrangement is on the closure spout and a substantially continu ⁇ ous second retaining arrangement is on the closure cap.
• the pitch of the second retaining surface is different in three different regions there is a different axial interaction between the first and the second retaining elements in the dif ⁇ ferent regions.
• a lower pitch provides for a stronger axial in ⁇ teraction which may prevent a sudden unintentional removing of the closure cap in case there is internal pressure.
• the rota ⁇ tion angle for opening the cap is smaller as compared with a low pitch thread.
• the closure cap may be removed in a controlled way especially in a first opening phase, when for the first time gas may escape from the container and a third phase, just before the closure cap is completely unscrewed.
• the closure spout may be adapted to fit to the container in any intended way, for example having s screw thread being suitable for standard container necks.
• the second retaining arrangement comprises a lower stopping area adjacent to said first region which provides a stopping abutment surface.
• the first retaining arrangement comprises a corresponding lower abutment surface on at least one of said first segments, which abuts against said lower stopping area to block or restrict rotation of said clo ⁇ sure cap in the direction of screwing on (hereinafter screwing direction) to define or to support the fully secured position.
• the second retaining arrangement comprises an upper stopping area adjacent to said third region which provides a stopping abutment surface.
• the first retaining arrangement comprises a corresponding upper abutment surface on at least one of said first segments which abuts against the upper stopping area to block or restrict rota ⁇ tion of said closure cap in the screwing direction to define or to support the fully secured position.
• Such an upper area pro ⁇ vides for an even better protection against overtightening.
• the stopping abutment surface may be part of the lower second retaining surface, may pass into the lower second retaining sur ⁇ face or may be a separate surface.
• the stopping abutment surface preferably tends to a rotational direction, more preferably the stopping abutment surface normal is perpendicular to the main axis of the closure assembly.
• said lower second re ⁇ taining surface further comprises a blocking step adjacent to said third region to provide a blocking abutment surface.
• the first retaining arrangement comprises a corresponding blocking abutment surface on at least one of said first segments which abuts against said blocking step to block or restrict rotation of said closure in an unscrewing direction at an intermediate position when said closure cap is under axial pressure in a di ⁇ rection emerging from the closure spout.
• closure spout and closure cap are constructed and arranged to provide a vent for venting gas from said con ⁇ tainer at least when said closure cap is in said intermediate position .
• closure spout and closure cap are con ⁇ structed and arranged to enable said step and said first retain ⁇ ing segments to be moved out of engagement by axial displacement of the closure cap downwardly, i.e. towards the container, on said closure spout at said intermediate position.
• Such an arrangement is therefore responsive not only to internal pressure acting on the closure cap, but also to external pres ⁇ sure applied by the person unscrewing the closure cap.
• closure cap will be held at the intermediate position until the internal pressure has reduced to a low level at which the closure cap may be easily pressed downwards. Further more, should the closure begin to spin uncontrollably when it is first unscrewed, the arrangement will act to hold the closure at the intermediate position until the pressure is re ⁇ cuted .
• At least a part of the lower surface and/or the stop ⁇ ping abutment surface in the first region of the second retain ⁇ ing segment forms a matching fit with at least a part of said upper surface and/or the corresponding abutment surface on one of said first retaining segments when the closure is fully se ⁇ cured on the container spout.
• At least a part of the lower sur ⁇ face and/or the stopping abutment surface in said third region of the second retaining segment forms a matching fit with at least a part of the upper surface and/or the corresponding abut ⁇ ment surface on one of said first retaining segments when the closure cap is fully secured on the closure spout.
• At least a part of the lower surface of the second retaining segment in the third region forms a matching fit with at least a part of the upper surface of the first segment sur ⁇ face when the closure cap is at said intermediate position and outwardly displaced on said container spout

• At least one of the first retaining segments comprises a back off cam arranged on the upper first retaining surface which abuts against a blocking step of the second retaining arrangement to block or restrict rotation of said closure in an unscrewing direction at the basically fully secured position.
• the back off cam provides for a resistance against simply start ⁇ ing to open the closure cap by turning it, especially in case there is an internal pressure.
• the back off cam may prevent a self-opening of the closure cap, for example during a transport of the container.
• An axial force from the inside of the container together with an accidental torque due to for example an external vibration would not be sufficient to open the closure cap.
• the back off cam may be constructed and arranged so as to get over the restriction relatively easily when opening torque is applied by a user, especially in case the closure assembly com ⁇ prises further safety features as described above.
• the first retaining arrangement is constructed and arranged such that when the closure cap is fully secured on the closure spout the first retaining arrangement contacts both the first and third region of the second retaining arrangement to provide a holding force in axial direction.

• the first retaining arrangement may comprise at least two axially displaced retaining segments whereof one contacts a first retaining region and a second one contacts a third retain ⁇ ing region in the fully secured position. Since in the first and third regions of the second retaining ar ⁇ rangement the segments have no pitch or have at least a lower pitch than in the second region, the contact between the first retaining segments and the first and third regions of the second retaining arrangement, primarily provides for an axial holding force. The axial force is necessary to hold the closure cap at the closure spout, especially when an internal pressure arises due to degassing of the beverage.
• the first retaining arrangement comprises at least one retaining segment with both an upper abutment surface and a back off cam, preferably addi ⁇ tionally an upper surface which provides for an axial force to ⁇ wards the second retaining arrangement when the closure cap is in the fully secured position, preferably with no pitch.

• closure spout is meant to remain fixed on the container when the closure assembly is opened and the closure cap is removed form the closure spout. Moreover in order to allow a comfortable opening of the closure assembly the closure spout should be blocked from rotating with respect to the container.
