None-out Straw / Straw

None-out Straw
None-out Straw

When drinking soft drinks with a straw, we always spill them just out of slightly incaution.
That is because the straw in being is tightly in contact with the pack, which makes the air pressure from inside the pack easily extrudes the liquid out from the straw.

None-out Straw, through the changing of a normal straw’s shape – big bottom and small top, makes the straw and the pack apart after inserting. In this way, when one squeezes the pack, air comes out from the gap between the straw and the pack, and awkward scenes like spilling liquid everywhere are smartly avoided.
