Closure cap for closing a container

Abstract

The invention relates to a closure cap for closing the pouring opening of a container, comprising a cylindrical threaded part including an open rim and an internal thread, which can cooperate with an external thread of a container neck of the container, a tamper-evident band, which is designed to be held at a protrusion formed at the container neck, and a retaining device including a first and a second end, the first end being fixedly connected to the open rim of the threaded part, and the second end being fixedly connected to the tamper-evident band. The retaining device comprises two first outer retaining strips and at least one second inner retaining strip, the at least one second retaining strip being arranged between the first retaining strips, and the first retaining strips being longer than the at least one second retaining strip.

         5 . The closure cap according to  claim 2 , wherein the first retaining strips and the at least one second retaining strip cooperate so as to become latchingly engaged in the second position, whereby the threaded part is fixed when the first and the at least one second retaining strips are in the second position. 
     
     
         6 . The closure cap according to  claim 2 , wherein the first retaining strips and the at least one second retaining strip form a snap-on hinge in that, in the second position, the at least one second retaining strip is bent, and the two first retaining strips are tensioned. 
     
     
         7 . The closure cap according to  claim 1 , wherein two second retaining strips are present. 
     
     
         8 . The closure cap according to  claim 1 , wherein the first and second retaining strips are formed of the tamper-evident band by way of cuts at the tamper-evident band. 
     
     
         9 . The closure cap according to  claim 1 , wherein in the first position, the second retaining strips are separated in each case from the first retaining strips by a first cut. 
     
     
         10 . The closure cap according to  claim 7 , further comprising a web is formed at the tamper-evident band between the two second retaining strips. 
     
     
         11 . The closure cap according to  claim 1 , wherein the first and second retaining strips each comprise a first and a second leg, the first and second legs being connected to one another by an arc, and the first legs including first ends that are fixedly connected to the open rim of the threaded part, and the second legs include second ends that are fixedly connected to the tamper-evident band. 
     
     
         12 . The closure cap according to  claim 11 , wherein in the first position, the first and second legs are in each case separated from one another by a second cut. 
     
     
         13 . The closure cap according to  claim 11 , wherein the arcs of the first retaining strips or the arcs of the second retaining strips face one another in the first position. 
     
     
         14 . The closure cap according to  claim 1 , wherein the first retaining strips are in each case separated from the tamper-evident band by a third cut. 
     
     
         15 . The closure cap according to  claim 14 , wherein the second retaining strips are in each case separated from the tamper-evident band by a fourth cut. 
     
     
         16 . The closure cap according to  claim 15 , wherein the first and fourth cuts are C-shaped. 
     
     
         17 . The closure cap according to  claim 14 , wherein the second cuts of the first retaining strips and the third cuts are connected to one another. 
     
     
         18 . The closure cap according to  claim 12 , wherein the first cuts and the second cuts of the second retaining strips are connected to one another. 
     
     
         19 . The closure cap according to  claim 1 , further comprising a plurality of protrusions formed on an inside of the tamper-evident band, and the first and second retaining strips are formed of the tamper-evident band above the plurality of protrusions. 
     
     
         20 . A container, comprising:
 a container body;   a container neck adjoining the container body;   an external thread formed at the container neck; and   a closure cap for closing a pouring opening provided within the container neck, the closure cap comprising:
 a cylindrical threaded part including an open rim and an internal thread, which cooperates with the external thread of the container neck,
