Abstract: A child's liquid drink container in the form of a canteen which is equipped with a drinking straw. The canteen has a dome-shaped rotatable cover with a hole in one side. The cover may be rotated to a first angular position in which an internal closure member closes the hole with the straw retracted into the cover. The cover may also be rotated to a second angular position in which the closure member moves away from the hole and in which the straw is caused to project out through the hole. This enables one to drink the liquid contained in the canteen quickly and easily and without the need to remove the cover.
