Closure made of a flexible plastic for containers, especially for bottles

Abstract

The inventive closure includes an annular part, to which a lid is joined by a hinge, and a the spout that is pushed inside the annular part. When pushing the spout into the annular part, the edge of the spout abuts against segments and is thus brought into the optimal drop-preventing shape. When closing the lid, the air in the slot can escape through the outlets so that it does not impede the closing or have the tendency to open the closure. Also during closing, the upper end of the spout comes into contact with the supporting surfaces, which are arranged in an interspaced manner inside the slot, whereby remaining liquid can be accommodated in the cavities.

1 . A closure of flexible plastic for containers, comprising: 
 a ring which has means for securing the closure to a container neck;    a lid which is joined to the ring by means of a hinge; and    a stopper that is surrounded on an upper end by an annular slot, having a tubular spout, which can be introduced sealingly by its lower end into the container neck and on the upper end has a drip-preventing edge of the spout, which when the closure is closed, engages the annular slot of the lid.    
     
     
         2 . The closure of  claim 1 , wherein the annular slot is formed by a space between the stopper and an annular flange disposed coaxially to the stopper.  
     
     
         3 . The closure of  claim 2 , wherein the outlet is formed by a slit in the annular flange.  
     
     
         4 . The closure of  claim 1 , wherein a diameter (d v ) of the spout measured via edges of the spout is greater than an outer diameter (d n ) of the annular slot.  
     
     
         5 . The closure of  claim 1 , wherein supporting surfaces for an end of the spout are provided, spaced apart from one another, on a bottom of the annular slot.  
     
     
         6 . The closure of  claim 1 , wherein a collar on the spout is provided, which when the closure is placed on the container neck comes to rest on an end of the container neck.  
     
     
         7 . The closure of  claim 6 , wherein the lid has cuffs which rest on the collar when the closure is closed.  
     
     
         8 . The closure of one of  claim 1 , formed as one piece.  
     
     
         9 . The closure of  claim 1 , wherein the spout is inserted as a separate part into the ring.  
     
     
         10 . The closure of  claim 1 , comprising a proof-of-originality strip that can be broken off.  
     
     
         11 . A closure of flexible plastic for containers, comprising: 
 a ring which has means for the closure to a container neck;    a lid which is joined to the ring by means of a hinge; and    a stopper that is surrounded on an upper end by an annular slot, having a tubular spout, which can be introduced sealingly by its lower end into the container neck and on the upper end has a drip-preventing edge of the spout, which when the closure is closed, engages the annular slot of the lid, wherein a diameter (d v ) of the spout measured via edges of the spout is greater than an outer diameter (d n ) of the annular slot.    
     
     
         12 . The closure of  claim 3 , wherein a diameter (d v ) of the spout measured via edges of the spout is greater than an outer diameter (d n ) of the annular slot.  
     
     
         13 . The closure of  claim 12 , wherein supporting surfaces for an end of the spout are provided, spaced apart from one another, on a bottom of the annular slot.  
     
     
         14 . The closure of  claim 13 , wherein a collar on the spout is provided, which when the closure is placed on the container neck comes to rest on an end of the container neck.  
     
     
         15 . The closure of  claim 14 , wherein the lid has cuffs which rest on the collar when the closure is closed.  
     
     
         16 . The closure of  claim 15 , formed as one piece.  
     
     
         17 . The closure of one of  claim 16 , wherein the spout is inserted as a separate part into the ring.  
     
     
         18 . The closure of  claim 17 , comprising a proof-of-originality strip that can be broken off.
