Abstract

A container comprising a container body ( 1 ) including an opening ( 4 ), a cap ( 5 ) to close the opening ( 4 ) and a collar ( 6 ), the collar ( 6 ) being arranged to fit between the container body ( 1 ) and the cap ( 5 ) so as to secure the cap ( 5 ) to the container body ( 1 ), the collar ( 6 ) being moveable between a contracted configuration and an expanded configuration such that circumferential parts ( 7 B) thereof are radially movable between inner and outer positions in the contracted and expanded configurations, the collar ( 6 ) and cap ( 5 ) being provided with mutually engageable parts ( 7, 5 D, 5 E, 5 F) permitting rotation of the cap ( 5 ) relative to the collar ( 6 ), said rotation causing and/or permitting movement of the collar ( 6 ) between the contracted and expanded configurations.

       19 . A container comprising a container body including an opening and having an externally projecting lip around said opening, a cap to close the opening and a collar, the collar being arranged to fit between the container body and the cap so as to secure the cap to the container body, the collar being moveable between a contracted configuration and an expanded configuration such that circumferentially extending parts of the collar are radially movable between inner and outer positions in the contracted and expanded configurations, the collar being mountable over the projecting lip in the expanded configuration and the collar, or at least parts thereof, being enagageable with an underside of the lip in the contracted configuration, the collar and cap being provided with mutually engageable parts permitting rotation of the cap relative to the collar, said rotation causing and/or permitting movement of the collar between the contracted and expanded configurations. 
   
   
       20 . A container as claimed in  claim 19  in which the collar comprises a ring, the diameter of which is reduced or enlarged to move between said contracted or expanded configurations. 
   
   
       21 . A container as claimed in  claim 20  in which the circumference of the ring can be reduced or enlarged so as to reduce or enlarge its diameter. 
   
   
       22 . A container as claimed in  claim 19  in which the cap and collar are initially pre-assembled wherein the collar is mounted over said projecting lip whilst assembled with the cap. 
   
   
       23 . A container as claimed in  claim 19  in which the collar is disposed removable from the container body together with the cap. 
   
   
       24 . A container as claimed in  claim 20  in which an upper edge of the ring engages the underside of the lip. 
   
   
       25 . A container as claimed in  claim 24  in which substantially the entire ring engages under the lip. 
   
   
       26 . A container as claimed in  claim 19  in which the collar comprises a ring with a break in it which permits the collar to move between expanded and contracted configurations. 
   
   
       27 . A container as claimed in  claim 19  in which the collar comprises a ring at least portions of which are resiliently circumferentially extendable such that the collar can move between expanded and contracted configurations. 
   
   
       28 . A container as claimed in  claim 19  in which the collar has a plurality of circumferentially extending radially movable parts which engage under the lip in the contracted configuration. 
   
   
       29 . A container as claimed in  claim 19  in which, in use, after being moved to the contracted configuration, the resilience of the collar, or parts thereof, moves the collar back to the expanded configuration. 
   
   
       30 . A container as claimed in  claim 19  in which the collar has one or more inwardly directed projections for engaging one or more stop features on the container body so as to inhibit rotation on the collar relative to the container body at least in the tightening direction. 
   
   
       31 . A container as claimed in  claim 30  in which said stop feature comprises one or more shallow recesses in an external wall of the container body. 
   
   
       32 . A container as claimed in  claim 30  in which said stop feature comprises one or more projections immediately beneath a lip of the container body. 
   
   
       33 . A combination for closing an opening of a container body having an externally projecting lip around the opening, the combination comprising a cap and a collar, the collar being arranged to fit between the container body and the cap so as to secure the cap to the container body, the collar being moveable between a contracted configuration and an expanded configuration such that circumferentially extending parts of the collar are radially movable between inner and outer positions in the contracted and expanded configurations, the collar being mountable over the projecting lip in the expanded configuration and the collar, or at least parts thereof, being engageable with an underside of the lip in the contracted configuration, the collar and cap being provided with mutually engageable parts permitting rotation of the cap relative to the collar, said rotation causing and/or permitting movement of the collar between the contracted and expanded configurations.
