octopus straw cup / Straw cup

flexible straw cup design which is able to control water pressure

Conventional straw cup for babies has stuffed nozzle to prevent spilling water and chocking when babies drinking while lying down.
However, this nozzle makes it hard to drink water while sitting or lying down.
This cup makes drinking easier by being able to control water pressure.
If you push the cup harder, more water comes out.
