straw- / Straw, Lifestyle, Drink

straw-

When we drink beverages or milk which are stored in boxes, after inserting a straw, we sometimes use more strength to pick up the box unconsciously. However, due to the full drinks, especially when you pick up the box firstly, a little bit of power will also make the liquid extrusion outside the box.
The mouth of our straw can be closed lightly when it is be produced. When people pick up the box at the first time, the liquid can’t be extrused outside because of the closing mouth of the straw. People just bite the mouth of the straw to be open when they put the straw into their mouth naturally.
