ABSTRACT:
The invention relates to a container (1) with a child-resistant cup-shaped closure (10), the opening of the said container (1) being a neck (2) with an external thread (3) in the form of a thread groove (4) for interaction with a radial projection (15) on the internal circular side wall (11) of the cup-shaped closure (10), whereby the thread (3) has a blocking device in that side (4a) of the thread groove (4) which is in frictional engagement with the projection (15) when the closure (10) is being unscrewed, so that the projection is caught by the blocking device when unscrewing the closure.
