Abstract:
An enclosure method comprising a first enclosure portion and a second enclosure portion configured to mate with the first enclosure portion. A receptacle is provided on the first enclosure portion. The receptacle has a frangible wall portion accessible from an exterior of the first enclosure portion. The frangible wall portion is operable to be broken from outside the enclosure method. A protrusion is provided on the second enclosure portion and the protrusion is operable to be received in the receptacle. A first locking member is connected to the frangible wall portion to extend inside the receptacle and a second locking member is provided on the protrusion. The second locking member is configured to engage the first locking member such that separation of the first and second enclosure portions is prevented unless the frangible wall portion is deliberately broken.
