  • Publication number: 20020145000
    Abstract: A non-spillable beverage container. The container includes a cover having a straw opening and a second vent opening. The vent opening is covered by a diaphragm attached at a plurality of points on the second vent opening. The diaphragm prevents the passage of air through the vent opening. With the vent opening covered, liquid contained within the container is locked within the container and prevented from exiting through a straw inserted within the straw opening. When a user inhales through the straw, air drawn through the straw from the interior of the container causes the diaphragm to bend downwardly and allow the passage of air into the container. The liquid may then exit through the straw. When the user discontinues inhaling through the straw, the diaphragm closes the vent opening and prevents liquid from exiting via the straw.

  • Patent number: 5307950
    Abstract: 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.
