Abstract: A canteen for children whose structure incorporates a drinking straw that also functions as a stopper. The canteen includes a cylindrical container for the liquid to be dispensed and a removable cover which is screwed onto the rim of the container and is provided with an off-center coupler. One end of the coupler projects from the underside of the cover to form a lower nipple to which is attached a long dip tube that extends into the container. The other end of the coupler projects from the top side of the cover to form an upper nipple to which is attached a short, flexible mouth tube, which in combination with the dip tube functions as a drinking straw. Mounted over the cover is a dome having a slot therein, the dome being turnable with respect to the cover from a drinking mode position in which the mouth tube then projects upwardly through the slot, to a sealing mode position in which the mouth tube is bent under the dome and is pinched at the bend so that it now acts as a stopper to seal the container.
