ABSTRACT:
In a container cap, comprising a primary cap provided with an outlet opening in a top wall thereof, and fitted to a mouth of a container, and a secondary cap having an end hinged to the top wall of the primary cap, a slide member slidably overlies an upper surface of the primary cap, and includes a ramp projection projecting vertically therefrom and a lateral projection extending laterally therefrom, and a cover member overlies the slide member. The ramp projection is adapted to move the secondary cap vertically in an opening direction by engaging the secondary cap via the cover member while the lateral projection is adapted to engage an inner surface of the hinge to force the secondary cap in an opening direction. Because the cover member overlies the slide member, the content of the container dripping or spilled from the outlet opening is shielded from the slide member by the cover member. To positively prevent the content from getting into the sliding surfaces of the slide member and to thereby ensure satisfactory operation of the mechanism for opening the secondary cap, preferably, the outlet opening is surrounded by an annular boss, and the cover member is provided with a boot portion closely surrounding the annular boss.
