Abstract: A cap for modifying the contents of a container with a modifying composition. The cap system permits a user to agitate the contents of the container without spillage. A collar assembly is removably mounted to the neck of a container and an elongated plunger shank is partially housed therein with a compartment for storing the composition. Upon the application of force on the plunger shank, the foil sheet covering the bottom hits the puncturing protrusion of the activator assembly, releasing the modification composition while maintaining the container in watertight condition preventing any spillage if shaken. The seal previously achieved by the shank is not being achieved by the valve seat of the spout assembly.

Abstract: A system for generating water with predetermined amount of ozone dissolved and minimum entrained ozone. The system includes the use of an entrained gas separator assembly in series with the recirculating plumbing feeding and discharging ozone enriched water. The novel entrained gas separator assembly allows the water with dissolved ozone to pass through while extracting the entrained ozone for subsequent use or destruction. The entrained gas separator includes a secondary tank with an off gas valve for releasing the entrained gases including ozone. A cylindrical member with a helicoidal wall and centrally perforated tube defines a helicoidal path that forces the water down allowing the entrained ozone to pass through. The ozone concentration is kept within predetermined levels with the use of an ozone analyzer mounted close to the outlet of the holding or contact tank, as well as a number of sensors and bypass valves that are computer controlled.
