Closing cap for a container

Abstract

Closure cap ( 1 ), produced by a plastics injection molding process, for a container ( 5 ) such as a bottle, has a closure lower part ( 2 ) and a closure cover ( 3 ) joined integrally to it by way of a hinged joint. The cover ( 3 ) pivots by a hinge ( 8 ) and latches in place in an open state to a closure lower part back wall ( 12 ). A latching projection ( 26 ) also is formed on this wall. A latching edge ( 27 ) on the closure cover ( 3 ), which latching edge, in the latching state, is overrun by the latching edge ( 27 ), is positioned to engage beneath the latching projection ( 26 ). An extension of the latching projection ( 26 ) intersects a vertical (V-V) through the hinge axis. The latching projection ( 26 ) is formed so as to yield during an overrunning in the pivoting direction.

       14 . Closure cap ( 1 ), suitable for production by a plastics injection molding process, for a container ( 5 ) including a bottle, the closure cap comprising a closure lower part ( 2 ) and a closure cover ( 3 ) which are joined integrally by a joint having a hinge, the closure cover ( 3 ) being pivotable by the hinge ( 8 ) and being latched in place in an open state to a back wall ( 12 ) of the closure lower part ( 2 ); wherein the closure cap further comprises a latching projection ( 26 ) formed on the back wall, and a latching edge ( 27 ) located on the closure cover ( 3 ); wherein the latching protection ( 26 ), in a latching state, is overrun by the latching edge ( 27 ), and the latching edge ( 27 ) is positioned such that it engages beneath the latching projection ( 26 ); wherein an extension of the latching projection ( 26 ), in the direction of its protrusion (z), as seen in cross section, intersects a vertical (V-V) through the hinge axis (x-x) below the hinge axis (x-x); and wherein the latching projection ( 26 ) is formed so as to yield during the overrunning in the pivoting direction (arrow y) of the latching edge ( 27 ) of the closure cover ( 3 ).  
   
   
       15 . Closure cap according to  claim 14 , wherein the latching edge ( 27 ) is formed closed to the pivot axis.  
   
   
       16 . Closure cap according to  claim 14 , wherein the boundary edge ( 15 ), associated with the latching projection ( 26 ) of the closure cover ( 3 ), is cut open in the axial direction of the hinge ( 8 ) to form the latching edge ( 27 ).  
   
   
       17 . Closure cap according to  claim 16 , wherein the latching projection ( 26 ) is formed as a resilient tongue.  
   
   
       18 . Closure cap according to  claim 16 , wherein the latching projection ( 26 ) is rooted in the axial region of the hinge ( 8 ).  
   
   
       19 . Closure cap according to  claim 14 , wherein the hinge axis (x-x) is disposed in the plane region of a closure top ( 19 ) of the closure lower part ( 2 ).  
   
   
       20 . Closure cap according to  claim 14 , wherein a formation of the latching projection ( 26 ) enables its surface to complement the hinge region.  
   
   
       21 . Closure cap according to  claim 16 , wherein the latching projection ( 26 ), located axially in front of the hinge ( 8 ), is provided in a pair.  
   
   
       22 . Closure cap according to  claim 14 , wherein the latching edge ( 27 ) is visible in a side view of the closed closure cap ( 1 ).  
   
   
       23 . Closure cap according to  claim 14 , wherein the latching edge ( 27 ), when the closed closure cap ( 1 ) is seen in plan view, is integrated in a peripheral boundary line ( 14 ) of the closure cap.  
   
   
       24 . Closure cap according to  claim 16 , wherein the latching projection ( 26 ) is formed centrally between two hinges ( 8 ,  8 ′).  
   
   
       25 . Closure cap according to  claim 14 , wherein the latching projection ( 26 ) has a rounded edge contour ( 33 ).  
   
   
       26 . Closure cap according to  claim 14 , wherein the latching projection ( 26 ) narrows in terms of cross section toward its free edge region.
