“help-yourself”bottle / Product Design

We designed bottle opener in new way,embed it into the design of the bottle.when you open a bottle ,you'll just take advantage of the special structure of the bottom that you can take off the cap of the bottle.
The concept is putting the problem and problem-solving method together.By means of their own tiny adjustment
to solve their own problem.Don't need to ues other tools. Aovid the inconvenience that must search for the other
specific tools to solve the problem.
