Abstract

An apparatus for manufacturing carbonated water according to the invention can quickly produce carbonated water with a high carbonic acid gas content which does not easily lose carbonic acid gas and hence satisfactorily stimulates the throat with agreeable pungency. Since it has a simple configuration and hence is economic and effective, it can suitably be used in an carbonated beverage supplying apparatus such as an automatic vending machine, an automatic dispenser or the like. With such an arrangement, the apparatus improves its safety and hence can constantly supply delicious carbonated water.

Claims

1. An apparatus for manufacturing carbonated water by contact between carbonic acid gas and water introduced into a carbonic acid gas pressure container, said apparatus comprises a cylindrical mist chamber arranged in the carbonic acid gas pressure container and having its top and peripheral walls hermetically sealed, said cylindrical mist chamber being provided with a spray at the top for introducing water therein and a semispherical projection having a diameter smaller than the inner diameter of the cylindrical mist chamber at the bottom, a coupling member for connecting said semispherical projection and the peripheral wall of the cylindrical mist chamber, said coupling member being provided with a large number of small holes for allowing water to pass therethrough, and a cylindrical metal network having open top and bottom and arranged under the coupling member so that water drops discharged from the spray collide with the surface of the semispherical projection and are atomized and dispersed in the cylindrical mist chamber to sufficiently get in touch with carbonic acid gas before they flow down through the small holes and the cylindrical metal network to the bottom of the carbonic acid gas pressure container.

2. An apparatus for manufacturing carbonated water according to claim 1, wherein the cylindrical metal network is so arranged that a lower end thereof is constantly held in contact with the carbonated water in the carbonic acid gas pressure container.
