ABSTRACT:
A child-proof screw-cap closure is described which can be screwed onto a bottle or the like container and comprises an inner cap, an outer cap, a coupling member and a sealing member, which inner cap possesses an inner chamber and a cavity, connected with one another by a passage and a channel with a window between the cavity and the chamber, and which outer cap possesses a projecting zone with at least one niche, which zone projects so far into the interior of the outer cap that, in the non-actuating position, it at least partially covers the window of the channel and prevents passage of the coupling member through the channel, whilst when the outer cap is rotated so that the niche faces the window, the coupling member can pass from the cavity into the window and project into the niche, as a result of which a positive engagement is made between the inner and outer cap and both caps can be unscrewed from the mouth of the container.
