Bottle or container closure for the precise addition of a contents constituent

Abstract

A bottle or container closure for a precise addition of a contents constituent includes a lower part having internal threads for a leak-proof application for the bottle or container, in which the lower part of the closure includes, in a clearance area, a chamber that can be closed with a membrane liner opening toward the bottom of the closure, which has a dome-shaped top side that includes a penetrating pin projecting downwardly inside the dome-shaped top side. The dome-shaped top side can be pressed downwardly, via deformation, so that the projecting pin can be pressed through the membrane liner. A pouring spout is located adjacent the chamber on the lower part of the closure, which releases through suction, or pressure, on the bottle or container. A covering lid is hinged to the lower part of the closure and can be swung on the body of the closure, in which a plug or a sleeve is present on the bottom side of the covering lid, so that the pouring spout can be closed in a leak-proof manner by the swinging of the covering lide on the lower part of the closure.

1 . A bottle or container closure for a precise addition of a contents constituent, comprising: 
 a pouring spout;    a covering lid;    a projecting pin; and,    a lower part having means for leak-proof assembly onto a bottle or container spout, said lower part further including a chamber within a clearance area closable with a membrane liner fused on an opening towards a bottom of said chamber with said chamber having a dome-shaped top side with said projecting pin projecting downwardly inside said dome-shaped top side of said chamber and with said dome-shaped top side being pressable downwardly under deformation through said membrane liner, said lower part having said pouring spout arranged adjacent said chamber with said covering lid being hinged to, and swingable on, said lower part.    
   
   
       2 . The bottle or container closure for a precise addition of a contents constituent according to  claim 1 , wherein said dome-shaped top side of said chamber includes strengthening ribs.  
   
   
       3 . The bottle or container closure for a precise addition of a contents constituent according to  claim 1 , further comprising a plug or sleeve on a bottom side of said covering lid and having stabilizing flanks for allowing said pouring spout to be closed in a leak-proof manner via swinging said cover lid on said lower part of said bottle or container closure.  
   
   
       4 . The bottle or container closure for a precise addition of a contents constituent according to  claim 1 , wherein said pouring spout is located at a periphery of said lower part and lying opposite a hinge for allowing said covering lid to be swingable on said lower part and with an upper portion of said lower part of said bottle or container closure forming a covered cap having a circular recess at an outer rim of said circular cap for seating a rim of said covering lid for closing said covering lid.  
   
   
       5 . The bottle or container closure for a precise addition of a contents constituent according to  claim 4 , wherein said pouring spout has an entry on an inner side for receiving a sleeve formed on a bottom side of said covering lid, said sleeve having a projecting bulge for a leak-proof closing of said covering lid.  
   
   
       6 . The bottle or container closure for a precise addition of a contents constituent according to  claim 5 , wherein said sleeve comprises stabilizing flanks surrounding said pouring spout for aiding in said leak-proof closing of said covering lid.  
   
   
       7 . The bottle or container closure for a precise addition of a contents constituent according to  claim 1 , wherein said projecting pin is part of a piercing device comprised of said dome-shaped top side in a lidded cover, or cap cover, that projects outwardly on said lower part of said bottle or container closure in a first position and is pressable into a second position via said deformation, said second position being an inward or lower projecting position, said piercing device having on its inner side, centrally located, said projecting pin, with strengthening ribs, projecting downwardly.  
   
   
       8 . The bottle or container closure for a precise addition of a contents constituent according to  claim 1 , wherein said dome-shaped top side includes stabilizing ribs on its bottom side, said stabilizing ribs being spirally-arranged.  
   
   
       9 . The bottle or container closure for a precise addition of a contents constituent according to  claim 1 , wherein said pouring spout has, on an inner side, a pressure membrane for preventing liquid constituent present in a bottle or container from leaking when said covering lid is open.  
   
   
       10 . The bottle or container closure for a precise addition of a contents constituent according to  claim 9 , wherein said pressure membrane allows release of said liquid constituent to pass through said pouring spout upon external pressure of the bottle or container.
