  • the consumer may wish to pour a large quantity of motor oil from the container 15.
  • the consumer may wish to remove the entire closure 10 from the container 15.
  • the contents are readily poured from the container 15.
  • This manner of removal of the closure 10 will lead to at least partial fracture of the frangible bridges 18 and these will provide an indication that the closure 10 has been removed previously from the container 15.
  • the consumer only wishes to dispense a small quantity of the contents with little or no mess, the option is open to use the tube 22. In this case the consumer would remove the tube 22 from the container 15. insert it into the bore 32 in the closure 10 and push downwardly until the tube 22 breaks through the membrane 35.
  • the retaining flanges 29 would spring outwardly so preventing the tube 22 falling out of the closure 10 during pouring of the contents from the container.
  • the tube 22 can be re-sealed by screwing the tube closure 25 back into the tube 22 and pushing the tube 22 fully into the container 15 until the tube closure 25 abuts the outer surface of the top portion 11.
