Synthetic bottle closure

Abstract

A closure ( 1 ) closes a mouth ( 2 ) of a bottle ( 3 ), wherein the bottle is made of glass and has an external outwardly extending integral collar ( 4 ) which extends fully around an outside of the neck of the bottle and is of a constant shape and size at any location around the periphery. The seal ( 5 ) is held under compression against an uppermost rim ( 6 ) of the bottle mouth ( 2 ) and surface ( 7 ), which is adapted to engage with compression force the seal ( 5 ). Upon extraction of portion ( 8 ) from within the mouth of the bottle, a “popping” sound is achieved by having the position of a sealing part ( 9 ) of the portion somewhat below the mouth prior to extraction so that there will be upon extraction an evacuation of the headspace within the bottle.

1 . A bottle closure where the bottle is of a type having a mouth to be closed, the closure having a body having an outer surround adapted to engage with an interlocking fit, an outwardly extending integral collar of the neck of the bottle, a seal adapted to be held under compression by the body against an uppermost rim of the bottle mouth, and a portion of the body adapted to be located within the mouth of the bottle and, at least during extraction, to effect a seal with an inner surface of the mouth of the bottle.  
   
   
       2 . A bottle closure as in  claim 1  further characterized in that the seal is comprised of at least in part a material providing substantial resistance to the passage of oxygen there through.  
   
   
       3 . A bottle closure as in  claim 1 , further characterized in that the seal is of a form and positioned as a part of the closure such that it will extend substantially across the mouth of the bottle when the closure is in a closure position in respect of a bottle so as to provide thereby at least substantial resistance of gas passage there past or there through.  
   
   
       4 . A bottle closure as in  claim 1 , further characterized in that the body is comprised of at least two parts which are assembled together with the seal held between the two parts where one of the parts is comprising the portion of the body adapted to be located within the mouth of the bottle.  
   
   
       5 . A bottle closure as in  claim 4  further characterized in that the body is an assembly where the portion of the body adapted to be located within the mouth of the bottle is attached to a portion of the body by connecting means.  
   
   
       6 . A bottle closure as in  claim 4  further characterized in that the two parts are joined by a metal means projecting mutually through the respective parts.  
   
   
       7 . A bottle closure as in  claim 4 , further characterized in that the two parts are joined by at least one finger of plastics material extending through the seal.  
   
   
       8 . A bottle closure as in  claim 1 , further characterized in that the interlocking fit is effected by an inwardly directed lip adapted to engage a lower edge of an integral collar of the bottle.  
   
   
       9 . A bottle closure as in  claim 8  further characterized in that the inwardly directed lip is attached to a remainder of the body such that the lip can be manually separated from the remainder of the body whereby to reduce the interlocking effect to allow for subsequent removal of the closure from a closure position in relation to a bottle.  
   
   
       10 . A bottle closure as in preceding  claim 9  further characterized in that the inwardly directed lip is provided by a tear away strip.  
   
   
       11 . A bottle closure in  claim 1 , that creates a liquid seal upon reinsertion of said closure in the bottle mouth of said bottle.  
   
   
       12 . A bottle closure as in  claim 1 , further characterized in that the inner portion of the body provides an outer surface which is provided by a thin wall such that there can be effected substantial resilience to maintain a closure, to afford, upon being withdrawn, a sealing engagement with the inner surface of the mouth of the bottle thereby.  
   
   
       13 . A bottle closure as in preceding  claim 4  further characterized in that the two parts are joined by a metal staple.  
   
   
       14 . A bottle closure as in  claim 1 , further characterized in that the closure has the body providing an outer surround and a projecting portion of the body adapted to be located projecting substantially into the mouth of the bottle moulded as integral one with the other.  
   
   
       15 . A bottle closure as in  claim 1 , further characterized in that the portion adapted to be located within the mouth of a bottle is of a shape where there is a bulbous end provided by a thin wall of plastics material.  
   
   
       16 . A bottle closure as in preceding  claim 15 , further characterized in that there is further included a gas resistant sealing material extending between a wall defining an upper end of the portion adapted to be located within the mouth of a bottle.  
   
   
       17 . A bottle closure as in  claim 1 , further characterized in that the portion adapted to be located within the mouth of a bottle is of a shape and length such that when extracted from a selected bottle with a selected quantity of liquid in the bottle that it can be expected to provide a popping sound.  
   
   
       18 . A bottle closure as in  claim 1 , further characterized in that the body is made from injection moulded plastics material.  
   
   
       19 . A bottle closure as in  claim 1 , further characterized in that there is included a further member including a projecting portion extending into an inner portion of the body so as to be supported thereby and including a further part or parts providing visually attractive features.  
   
   
       20 . The combination of a bottle and a closure according to  claim 1 , when in a closing position with respect to the mouth of the bottle.  
   
   
       21 . The combination of a bottle and a closure according to  claim 1 , further characterised in that said closure covered by a capsule.  
   
   
       22 . A method of closure of a bottle which includes the steps of inserting a closure characterized according to  claim 1 , into a bottle including forcing the inwardly directed lip to ride over and behind the edge of the integral collar and being arranged so that this will, in this position, effect substantive compression of a seal between the body of the closure and an uppermost edge of the rim of the bottle.  
   
   
       23 . A method as in preceding  claim 19  further characterized in that the body includes means adapted to receive a further member.  
   
   
       24 . A method as in preceding  claim 19  further characterized in that such a further member includes a projecting portion extending into an inner portion of the body so as to be supported thereby and including a further part or parts providing visually attractive features.
