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. In order to make it possible for a user who does not know the position of the blocking device in relation to the projection (15) on the inside (12) of the circular wall (11) of the closure (10) to open the container, the width (b) of the thread groove (4) on the last portion of the rotation which is closest to the container (1), is expanded in axial direction in relation to the width (a) of the remaining outermost portion of the thread groove (4) and the passage between the expanded portion and the remaining portion of the thread groove (4) is configured as a stop (7, 8) to catch the projection (15) of the closure (10). |
