20130181005 | NO STRAW LIQUID POUCH - A flexible tube check valve is introduced within a fluid path for leakage protection from flexible liquid containers. The flexible check valve can be a crossbill valve comprising multiple flexible members that restrict the flow of fluid in a tubular member. The flexible check valve is preferably functionally integrated with the container itself to prevent liquid from exiting a container. Preferably, the flexible check valve is a crossbill valve that is encapsulated within a flexible tube and mechanically attached to the flexible container. Alternatively, the check valve is manufactured as part of the flexible container. Liquid is designed to only flow through when an external compressive force (e.g. users fingers or lips) is applied to the valve. When force is no longer applied to the valve section, the valve returns to its normally closed position and fluid is wholly or substantially prevented from exiting. An alternative medical embodiment uses a flexible tube extension between the flexible liquid container and the flexible tube valve. A coupling connector may be added between the flexible tube extension and flexible tube valve. | 07-18-2013 |
20110108613 | SNAP-FIT VALVE AND STRAW ASSEMBLY AND METHOD OF USING SAME - The present invention relates to a leakage prevention straw, a method of manufacturing the leakage prevention straw, and containers employing the leakage prevention straw. In accordance with the present invention, the leakage prevention straw has an open-ended, hollow tube; an open-ended, hollow receiver sealably mounted on the tube; a valve assembly sealably engaging the receiver; and a resilient locking adapter disposed on the tube and lockingly engaging the valve assembly to secure the valve assembly in liquid seal engagement with the receiver. The valve assembly has a hollow, open-ended, resilient enclosure and a check valve disposed within the enclosure. Although the check valve is biased in a closed position, the check valve opens upon manual manipulation of the enclosure. | 05-12-2011 |
