Stopper for bottles and similar containers

Abstract

A stopper for containers with a neck. The stopper includes a resilient and deformable tubular cylindrical assembly ( 20 ) that partially receives a pin assembly ( 70 ) through one end and a plug assembly ( 100 ) through the other end. The tubular cylindrical assembly ( 20 ) includes a central through opening ( 21 ) where the pin assembly ( 70 ) and the plug assembly ( 100 ) mate urging closer together as pin assembly ( 70 ) is rotated. The frustroconical distal termination of the plug assembly ( 100 ) pushes the end ( 22 ) of the tubular cylindrical assembly ( 20 ) towards the internal surface of the container neck achieving the sealing engagement that protects the contents of the container.

       5 . A bottle stopper, comprising: 
 A) a deformable and resilient tubular cylindrical member having an elongated body with first and second ends with a central through opening, said first end including a first peripheral flange, and the diameter of said elongated body being substantially the same as the diameter of the internal surface of a bottle neck;    B) a pin assembly having third and fourth ends, said third end including a second peripheral flange having substantially the same diameter as the diameter of said first peripheral flange and further including a threaded portion adjacent to said fourth end and extending a first predetermined distance; and    C) an elongated plug assembly having fifth and sixth ends, said fifth end having a frustroconical shape with the broader end defining the distal termination of said fifth end and said sixth end including an opening with an adjacent central threaded cavity that extends axially within said plug assembly a second predetermined distance from said sixth end, said threaded central threaded cavity cooperatively receives said threaded portion within said central through opening and said fifth end is urged against said second end so that said cylindrical tubular member houses said threaded portion and said plug assembly being partially inserted within said neck and said threaded portion is rotated and caused to travel axially within said central threaded cavity toward said fifth end thereby causing said frustroconical shaped fifth end to deform radially outwardly said second end resulting in a sealed engagement against said internal surface.    
   
   
       6 . The stopper set forth in  claim 5  wherein said tubular cylindrical member is made out of a soft rubber material.  
   
   
       7 . A bottle stopper, comprising: 
 A) a deformable and resilient tubular cylindrical member having an elongated body with first and second ends with a central through opening, said first end including a first peripheral flange, and the diameter of said elongated body being substantially the same as the diameter of the internal surface of a bottle neck;    B) a pin assembly having third and fourth ends, said third end including a second peripheral flange having substantially the same diameter of said first peripheral flange and said fourth end including an opening with an adjacent central threaded cavity that extends axially within said pin assembly a predetermined distance from said fourth end; and    C) an elongated plug assembly having fifth and sixth ends, said fifth end having a frustroconical shape with the broader end defining the distal termination of said fifth end and said elongated plug assembly having an external threaded portion adjacent to said sixth end and extending a first predetermined distance matingly receivable within said threaded cavity so that said cylindrical tubular member houses said threaded portion and said plug assembly being partially inserted within said neck, said pin assembly is rotated causing said plug assembly to travel axially within said threaded cavity toward said second peripheral flange thereby causing said frustroconical shaped fifth end to deform said second end resulting in a sealed engagement against said internal surface.    
   
   
       8 . The stopper set forth in  claim 7  wherein said tubular cylindrical member is made out of a soft rubber material.
