Resource-saving closure device

Abstract

A closure unit for selectively closing or releasing a container opening of a container. The closure unit includes a closure cap, wherein the closure cap has a cap cover plate and a cap skirt adjoining the cap cover plate on the circumferential side. The cap skirt extends at least in sections cylindrically and/or conically about a closure cap axis. The cap skirt has an outer surface directed away from the closure cap axis and an inner surface directed towards the closure cap axis. The closure cap has a first guide which is arranged on the inner surface of the cap skirt, wherein the first guide is configured and arranged in such a way that it can be brought into engagement with a second guide of a container in order to close the container opening of the container.

1 . A closure unit for selectively closing or opening a container opening of a container, wherein the closure unit comprises:
 a closure cap, wherein the closure cap has a cap cover plate and a cap skirt adjoining the cap cover plate on the circumferential side,   wherein the cap skirt extends at least in sections cylindrically and/or conically around a closure cap axis,   wherein the cap skirt has an outer surface directed away from the closure cap axis and an inner surface directed towards the closure cap axis,   wherein the closure cap has a first guiding means which is arranged on the inner surface of the cap skirt,   wherein the first guiding means is configured and arranged in such a way that it can be brought into engagement with a second guiding means of a container in order to close the container opening of the container,   wherein a lattice structure band composed of a plurality of first recesses and webs is provided in the inner surface of a cylindrical section of the cap skirt,   wherein the lattice structure band extends in the circumferential direction and has a sequence of the webs and first recesses,   wherein a first recess is arranged in each case between two webs in the circumferential direction,   wherein the lattice structure band is arranged on a side of the first guiding means facing away from the cap cover plate and/or on a side of the first guiding means facing the cap cover plate and/or between two guiding means segments arranged one above the other in the direction of the closure cap axis.   
     
     
         2 . The closure unit according to  claim 1 , wherein the lattice structure band has at least two sections spaced apart from each other in the circumferential direction. 
     
     
         3 . The closure unit according to  claim 1 , wherein the lattice structure band extends over at least one circumferential angle section over which the first guiding means extends. 
     
     
         4 . The closure unit according to  claim 1 , wherein the dimension of the lattice structure band or its section in the direction of the closure cap axis corresponds in each case to the length of the respective first recess including the side walls of the first recess adjoining in the direction of the closure cap axis in this direction and is smaller than the extent of the first guiding means in the direction of the closure cap axis. 
     
     
         5 . The closure unit according to  claim 4 , wherein the first guiding means has at least one second recess which extends in the direction of the closure cap axis and whose dimension in the direction of the closure cap axis is greater than or equal to the extent of the guiding means in the direction of the closure cap axis. 
     
     
         6 . The closure unit according to  claim 5 , wherein elevations are configured on the outer surface of the cap skirt, wherein each elevation runs parallel with a second recess in such a way that the cap skirt has a U-shaped profile in the region of the second recess. 
     
     
         7 . The closure unit according to  claim 5 , wherein the lattice structure band is arranged in a section of the cap skirt which is arranged below the end of the second recess facing away from the cap cover plate, or begins in a section of the cap skirt at this end of the second recess and extends in the axial direction away from the cap cover plate. 
     
     
         8 . The closure unit according to  claim 5 , wherein the plurality of first recesses, viewed in the circumferential direction, are arranged in sections lying between two circumferentially adjacent second recesses. 
     
     
         9 . The closure unit according to  claim 1 , wherein each first recess has a rectangular, triangular, circular, elliptical or polygonal shape or a shape composed of these shapes when viewed in the plane of an unrolled cap skirt. 
     
     
         10 . The closure unit according to  claim 1 , wherein the first recesses have similar shapes when viewed in the plane of the unrolled cap skirt. 
     
     
         11 . The closure unit according to  claim 1 , wherein the first recesses are arranged in a section of the lattice structure band in groups of three first recesses arranged next to each other in the circumferential direction. 
     
     
         12 . The closure unit according to  claim 1 , wherein the recess base of each first recess is planar in shape and extends parallel or obliquely to the closure cap axis. 
     
     
         13 . The closure unit according to  claim 1 , wherein the lattice structure band extends, optionally in sections, over a circumferential angle of at least 180°. 
     
     
         14 . A combination comprising: a container with closure unit according to  claim 1 ,
 wherein the container has a container opening and a second guiding means and the closure unit cooperates with the container for selectively closing or releasing the container opening, wherein the first guiding means of the closure unit can be brought into engagement with the second guiding means of the container for this purpose.   
     
     
         15 . The closure unit according to  claim 4 , wherein the webs extend in each case over the entire dimension of the respective lattice structure band in the direction of the closure cap axis.
