SHARE / Outdoor water bottle

SHARE is an outdoor water bottle; its highlight is that users can share the water in their own bottles with others. When a few friends go out for outdoor sports, what to do if some have finished the water in their bottles but are
still thirsty and need more water?SHARE has a roll of folded paper cups (replaceable after use) inside it. When a friend needs water, users can
just gently rotate the bottom to expose cups, tear off a paper cup, and share the water in their bottles.
