A pair of openings in the top of a container for liquids are normally closed by a pair of stoppers. The stoppers are mounted on the arms of a Y-shaped spring. The leg of the spring extends through a hole in the side of the container. The leg is connected to the upper end of a handle, which is connected to the container so that the handle pivots about the lower end of the handle. As the handle is pivoted, the leg of the spring is pulled outward through the hole in the side of the container. As the leg is pulled, the arms of the spring are pulled through a restraint, which pushes the arms together. This action pulls the stoppers away from the openings in the top of the container. The container also has a straw and a one-way valve. The valve allows air to enter the container, but does not allow liquid to spill from the container.
