Patent ID: 8439213

Claim:
A security closure assembly ( 1 ) for a mouth of a container having a longitudinal axis, comprising: a pourer unit ( 2 ) having a lower portion ( 3 ) for fixing to the mouth of the container and an upper pouring portion ( 4 ); a removable cap ( 6 ) which can be fitted onto the pourer unit ( 2 ) as far as a closure position in which the cap ( 6 ) is in abutment with a stop surface ( 4 a ), the cap ( 6 ) having at least one resiliently deformable peripheral lip portion ( 7 ); and an outer covering ( 8 , 9 ) including: an upper sleeve element ( 8 ) which closely surrounds the cap ( 6 ) leaving the lip portion ( 7 ) thereof substantially exposed, and a lower sleeve element ( 9 ) which is separate from the upper sleeve element ( 8 ) and closely surrounds the lower portion ( 3 ) of the pourer unit ( 2 ) and which, prior to a first opening of the closure assembly ( 1 ), extends at a predetermined distance (d) from the upper sleeve element ( 8 ) and at least partially surrounds the lip portion ( 7 ) of the cap ( 6 ), wherein, after the first opening of the closure assembly ( 1 ), that is, a first disconnection of the cap ( 6 ) from the pourer unit ( 2 ), the lip portion ( 7 ) is released from the lower sleeve element ( 9 ) and, upon subsequent re-closure, extends outside the lower sleeve element ( 9 ) and indicates that the closure assembly ( 1 ) has been opened, wherein prior to the first opening of the closure assembly ( 1 ), the lower sleeve element ( 9 ) of the outer covering ( 8 , 9 ) keeps the lip portion ( 7 ) in a radially compressed condition in which it is drawn in resiliently towards the longitudinal axis of the closure assembly ( 1 ), and is resiliently biased towards an opened-out condition in which it is opened out radially, and wherein after the first opening of the closure assembly ( 1 ), the lip portion ( 7 ) is arranged in the opened-out condition, in which it extends at least partially radially outside of the lower sleeve element ( 9 ) so as to permit subsequent re-fitting of the cap ( 6 ) on the pourer unit ( 2 ) as far as said closure position in which the lower sleeve element ( 9 ) and the upper sleeve element ( 8 ) once more extend the predetermined distance (d) apart.
