Three-part closure sealing and dispensing device for all types of Containers

Abstract

A container closure device with a flexible three-dimensional formed sealing wad with a circumferential ridge, the closure body ( 1 ) is formed with a top wall and a cylindrical wall, wherein the top wall has a circumferential trapezoidal groove on the inner side of its rim, adjacent to the cylindrical wall. A sealing wad ( 2 ) is arranged below the inner side of the top wall of the closure body, whereby the ridge is located under the groove and has an internal circumferential recess in the ridge running around the perimeter of the underneath side of the sealing wad, serving to receive the edge of the spout forming the opening of the container, whereby the protruding ridge is oversized compared to the groove, the width of the recess is reduced and compressed when the ridge is forced into the groove. The recess has sealing fingers and on its inner and outer side walls which creates the seal with the container.

         5 . Closure device according to  claim 1 , characterized in that the inside of the cylindrical wall has a thread for screwing it onto the spout of a container. 
     
     
         6 . Closure device according to any one of the preceding claims, characterized in that glue and/or bonding agent is applied in the recess or spout so that the sealing wad ( 2 ) is bonded to the edge of the spout. 
     
     
         7 . Closure device according to  claim 6 , characterized in that the sealing wad ( 2 ) has a child resistant tamper-proof closure lid. 
     
     
         8 . Closure device according to  claim 7 , characterized in that the closure lid is formed in the sealing wad by a circumferential weakened indentation in the sealing wad. 
     
     
         9 . Closure device according to  claim 8 , characterized in that the closure lid has a recess for placing a finger therein or a hinge pull-ring tab leaver. 
     
     
         10 . Closure device according to any one of the preceding claims, characterized in that an aluminium induction sealing foil lamination ( 3 ) is attached to the underneath side of the sealing wad ( 2 ). 
     
     
         11 . Closure device according to any one of the preceding claims, characterized in that closure device has an oxygen scavenger device. 
     
     
         12 . Closure device for the opening of a container comprising
 a closure body ( 1 ) with a top wall and a cylindrical wall, wherein the top wall has a circumferential trapezoidal groove on the inner side of its rim adjacent to the cylindrical wall, and wherein the groove has a top wall ( 1   a ) and inner and outer angle side walls ( 1   c  and  1   d ), and a flat sealing wad ( 5 ) arranged below the inner side of the top wall of the closure body, whereby a recess groove ( 13 ) is formed on the inside of the cylindrical wall into which the outer edge of the sealing wad ( 2 ) protrudes to be held therein loosely   so that the sealing wad ( 5 ) is pressed into the groove by the edge  10  of the spout forming the opening of the container when the closure body ( 1 ) is put onto the container engaging the edge ( 10 ) of the spout.   
     
     
         13 . Closure device according to any one of the preceding claims, characterized in that the closure device has a dispensing compartment ( 16 ) for a container, the closure body ( 1 ) being operable to dispense at least one product carried by the compartment device ( 16 ) into the container, the container having a spout portion with which the closure body ( 1 ) is engaged, the closure device comprising.
 a compartment to contain at least one product to be dispensed, the compartment being adapted to fit at least partly within the container spout and being defined by a substantially cylindrical side wall, a top wall, and a removable bottom wall, wherein the removable bottom wall is detachably engaged with the closure body ( 1 ).
