This kind of bottle has a change at neck with an adjustable structure. The bottleneck can be adjusted 360°to fulfill different angles of drinking need. Distinguishing from present bottles, the user doesn’t need to raise head up when drinking the last drop with this one, which avoids the discomfort on neck and water inhaling. The "free drinking" bottle gives drinking more simple, safety and comfort.
