ABSTRACT:
A liquid storage container has a tubule (11) which is open at one end and which is closed in liquid-tight manner at the front end face by a closure (12) which can be removed and/or opened for the filling of liquid into the tubule and/or for the removal thereof. An auxiliary closure cap (14) is provided for the closed tubule and has a locking ring 13 at its front open side. The auxiliary closure cap (14) is mountable onto the front end of the tubule (11), so that it covers over the closure (12) towards the outside. The locking ring (13) then snaps over a latch means (15) provided at the outer wall of the tubule (11) in its front region. The locking ring (13) is contrived so that it cannot be straightforwardly removed from the latch means by pulling it axially in the forward direction. In this way it is possible to check whether the liquid storage container has been tampered with.
