Collapsible bottle / Collapsible drinking bottle

Collapsible bottle

When you have bought a bottle of purified water, it looks just like other bottles.
But when you have drunk a half of it, you feel it a bit space consuming when hold in hand or put into backpacks, you can compress it from two ends of the bottle, into a smaller one.
At last, when you have drunk all of it, you can compress it into the smallest size before throwing it into the rubbish bin; this will gain convenience for recycling and help to reduce transportation cost.
