Ark Sip Tip Cup with Select Flow Valve

This cup makes drinking easier for individuals who have difficulty generating and maintaining suction. An individual can either suck from the straw themselves, or you can assist by "pumping" the fluid up the straw with the flexible lid. Simply cover the vent hole with your finger and press down several times until the liquid reaches the desired height. The Select-Flow Valve will keep the straw full of fluid, thereby reducing the air ingested and the effort required for each sip (notice the juice staying at the top of the straw in one of the images above). The valve also slows the flow of fluid, which allows for more control over the quantity of fluid taken with each sip and helps to ensure that fluid is deposited in the front of the mouth. This pack comes with a 230ml tumbler, a spill resistant lid, a select-Flow valve, 10 x straws, and a free lip blok (to prevent the straw from pushing too far into the mouth).
