ABSTRACT:
An automatic pop-up straw assembly comprises an outer tube, an inner tube, a resilient tube and a base. An air-tight connection between the inner tube and the resilient tube is achieved by inserting a reduced diameter of the second head of the resilient tube into the inner tube. Because the inner tube and the resilient tube are slidably received in the outer tube after the base is secured to the outer tube, the straw assembly is ready to be retained within a container with the compression of a helical tube of the resilient tube and the assembly will automatically pop-up when a cap of the container is opened.
