Abstract: A drinking spout for beverage cans, bottles, cups or handheld containers that temporarily hold a drinking fluid (beverage), which can be carbonated or a hot drink under pressure and which is closed off by the spout. Spilling of the fluid held therein is prevented during awkward drinking situations such as in cars while driving, walking or other less controlled drinking conditions. The fluid in the container, remains under pressure while permanent access is possible through the spout. The spout comprises a suction piece that is leak tight attached to a valve housing which holds a spring, a centrally perforated inverted membrane and a valve. When suction is applied to the spout, the inverted membrane moves downwards thereby opening the valve against the internal pressure of the bottle or container and allowing fluid to pass to the mouth. When the suction stops, a spring closes the valve. Air venting is provided, through the same valve, when the internal gas pressure drops below the atmospheric pressure.

Abstract: The invention relates to an “SRS” with suction spout for beverage cans (canteens), bottles, cups or handheld containers that temporarily hold a carbonated fluid or hot drink under pressure and that is closed off with a top, holding an SRS. Spilling of the fluid held therein is prevented during awkward drinking situations such as in cars while driving, walking or other less controlled drinking conditions. The fluid in a beverage can, remains under pressure of the carbonation process while permanent access is possible through the subject SRS. For non pressurized fluids air is entered through the same valve in order to prevent a vacuum in the container when being emptied, which would reduce the fluid flow while drinking. In all situations and positions of the container, no spilling of the fluid is possible. In case of an aluminum beverage cans, the spout is permanently attached to the lid of the can, but may be removable when used for a drinking cup, bottle or handheld container.

Abstract: The metered dual dispenser cap is for dual compartmented squeeze type containers which separately contain two distinct materials. The metered dual dispenser cap has a lower portion which is reciprocally attached to an upper portion. The lower portion has two inlets, each regulated by one way valves. The two inlets lead to two chambers which in turn lead through two outlet shafts to two dispensing outlets in the upper portion. The flow from the two chambers to the two dispensing outlets is regulated by two one way valves which are controlled by a push button on top of the cap. The volume expansion of the chambers, as the upper portion is pulled away from the lower portion, may be determined from optional scale gradations on the outer male wall. The scale gradations are increasingly exposed as the upper portion is pulled away to increase the volume in the chambers.
