Cap device for mixing different kinds of materials separately contained therein and in bottle

Abstract

A cap device for bottles allows an additive and a material to be separately stored in the cap device and a bottle, thus preventing the additive from being undesirably added to the bottled material. Furthermore, the cap device may contain a semisolid additive therein, as desired, thus allowing a user to mix the semisolid additive with the bottled material to prepare a mixture. The cap device has a cap body tightened to a mouth or an open lower end of the bottle, with an additive discharging means provided in the cap body to discharge the additive from a space inside the cap body into the bottle. The cap device further has a valve means for opening or closing the discharging means, according to a rotating action of the cap device relative to the bottle. The valve means includes a valve part which is brought into close contact with or spaced apart from the discharging means, thus closing or opening the discharging means to allow the additive to be discharged into the bottle to prepare the mixture. The valve means further includes a plurality of radial or vertical ribs which are integrated with the valve part into a single structure.
