Swollen / Trash

Do you want to have a trash can that it will never overflow ?
Sometimes people may become too lazy to dump garbage after working all day, but when ashcan are full out of rubbish, there is a trash can like bottomless pit , you can plug lots of garbage that it won’t full.
Do you want it?
Trash can exudes taste and food debris will bring ants, scientists pointed out that the rubber can effectively prevent the ants, Therefore, I choose this material of rubber, the inspiration is from balloon. Rubber’s elasticity can make balloon inflate and shrink repeatedly, I designed this lines with the garbage been thrown into and be expanded constantly Unt
