Bottle With A Secure Cap

Abstract

A bottle ( 1 ) with a secure cap ( 7 ), comprising a bottle having an open neck ( 2 ) and a first retaining flange ( 3 ) around at least a portion of the neck; and a push-on cap ( 7 ) fitted over the neck ( 2 ), the cap having an outlet with a valve ( 32 ) for controlling flow through the outlet and a second retaining flange ( 9 ) positioned so that, upon placement of the cap ( 7 ) on the bottle ( 1 ), the first and second retaining flanges ( 3,9 ) deflect relatively to one another as they pass and snap back into place once they have passed with a shoulder ( 41 ) of the first retaining flange engaging a shoulder ( 131 ) on the second retaining flange to hold the cap securely on the bottle.

1 . A bottle with a secure cap comprising:
 a bottle, having an open neck and a first retaining flange around at least a portion of the neck; and   a push-on cap fitted over the neck, the cap having an outlet and a second retaining flange positioned so that, upon placement of the cap on the bottle, the first and second retaining flanges deflect relatively to one another as they pass and snap bad into place once they have passed with a shoulder of the first retaining flange engaging a shoulder on the second retaining flange to hold the cap securely on the bottle;   one of the bottle neck and cap having a protrusion Which fits into a complimentary recess on the other of the bottle neck and cap to substantially prevent rotation of the cap and bottle.   
     
     
         2 . A bottle according to  claim 1 , wherein the first and second flanges are configured so that one or both of them is arranged to be damaged if the cap is removed from the bottle thereby compromising the functionality of the cap. 
     
     
         3 . A bottle according to  claim 1 , wherein the cap is provided with an auxiliary flange which is positioned so that, with the cap on the bottle, the first retaining flange is retained between the second retaining flange and the auxiliary flange, 
     
     
         4 . A bottle according to  claim 1 , wherein there is more than one protrusion and corresponding complimentary recess. 
     
     
         5 . A bottle according to  claim 1 , wherein the recess is defined by a pair of ribs which extend between an outer skirt of the cap and an inner circumferential element which defines the second retaining flange. 
     
     
         6 . A bottle, according to  claim 1 , the outlet having a valve for controlling flow through the outlet. 
     
     
         7 . A bottle according to  claim 1 , wherein the outlet is closed by a closure which is operable by a non-rotational movement. 
     
     
         8 . A bottle with a secure cap comprising:
 a bottle having an open neck and a first retaining flange around at least a portion of the neck; and   a push-on cap fitted over the neck, the cap having an outlet which is closed by a closure which is openable by a non-rotational movement and a second retaining flange positioned so that, upon placement of the cap on the bottle, the first and second retaining flanges deflect relatively to one another as they pass and snap back into place once they have passed with a shoulder of the first retaining flange engaging a shoulder on the second retaining flange to hold the cap securely on the bottle;   one of the bottle neck and cap having a protrusion which fits into a complimentary recess on the other of the bottle neck and cap to limit or prevent rotation of the cap and bottle.   
     
     
         9 . A bottle according to  claim 8 , wherein the closure is a resiliently deformable member. 
     
     
         10 . A bottle according to  claim 8 , wherein the first and second flanges are configured so that one or both of them is arranged to be damaged if the cap is removed from the bottle thereby compromising the functionality of the cap. 
     
     
         11 . A bottle according to  claim 8 , wherein the cap is provided with an auxiliary flange which is positioned so that, with the cap on the bottle, the first retaining flange is retained between the second retaining flange and the auxiliary flange. 
     
     
         12 . A bottle according to  claim 1 , wherein there is more than one protrusion and corresponding complimentary recess. 
     
     
         13 . A bottle according to  claim 1 , wherein the recess is defined by a pair of ribs which extend between an outer skirt of the cap and an inner circumferential element which defines the second retaining flange. 
     
     
         14 . A bottle according to  claim 1 , the outlet having a valve for controlling flow through the outlet.
