Containers and closures

Abstract

There is a resealable closure for plastic containers of a type having a mouth ( 7 ) formed with an inner neck bore ( 8 ) and spaced apart neck stubs ( 9 ) arranged around the outside of the neck. The closure in one position of use has a top panel ( 1 ), a peripheral downwardly extending skirt ( 2 ) with inwardly directed locking lugs ( 3 ) and an inner spigot seal ( 4 ) dimensioned for an interference fit into said neck bore ( 8 ). The closure is adapted to removably seal the container by push fitting the spigot seal ( 4 ) into engagement with said neck bore and subsequently locking the closure by rotation to a position where the locking lugs ( 3 ) align under the neck stubs ( 9 ).

1 . A resealable closure and a container, the container having a neck with an inner bore and spaced apart stubs arranged around the outside thereof, said closure in one position of use having a top panel, a peripheral downwardly extending skirt with inwardly directed locking lugs and a spigot seal formed on an inside surface of said top panel dimensioned for an interference fit into said bore whereby the closure is adapted to removably seal said container by push fitting the spigot seal into engagement with said bore at an unlocked position where the lugs are offset to clear said neck stubs and subsequently rotating said closure to a locked position where the lugs align under said neck stubs. 
     
     
         2 . The resealable closure and container as claimed in  claim 1  wherein the stubs and locking lugs are dimensioned and positioned to cause distortion upon rotation said closure to said locked position whereby frictional resistance holds the closure at said locked position. 
     
     
         3 . The resealable closure and container as claimed in  claim 1  wherein said locking lugs and stubs are shaped to enable said closure to move in either rotational direction between said locked and unlocked positions. 
     
     
         4 . The resealable closure and container as claimed in  claim 1  wherein said stubs have locating flats for engagement with the locking lugs. 
     
     
         5 . The resealable closure and container as claimed in  claim 1  wherein the closure has a profile which matches the shape of said container when at said locked position. 
     
     
         6 . The resealable closure and container as claimed in  claim 1  wherein said locking lugs are in the form of tapered catch plates to enable initial locking of the closure onto the container without rotation. 
     
     
         7 . The resealable closure and container as claimed in  claim 5  wherein said profile is hexagonal. 
     
     
         8 . The resealable closure and container as claimed in  claim 5  wherein said profile is rectangular. 
     
     
         9 . A resealable closure for a container, said closure in one position of use having a top panel, a peripheral downwardly extending skirt with inwardly directed locking lugs and a spigot seal formed on an underside surface of said top panel. 
     
     
         10 . The resealable closure as claimed in  claim 9  wherein said locking lugs are in the form of tapered catch plates.
