Spill resistant lid

A spill resistant lid adapted to be removably and sealably attached to an open topped container having an outside wall with a lip around the top of the outside wall and an inside wall with the inside wall forming an inside diameter of the container, comprising:

• a first cylindrical wall;
• a second cylindrical wall spaced inwardly from and connected to the first cylindrical wall to form a channel therebetween to receive the open top of said container;
• a ridge in the first cylindrical wall extending into the channel, said first cylindrical wall and ridge cooperating to allow the first cylindrical wall and ridge to move under downward pressure applied to the lid with regard to the container to enlarge the channel when the top of the container with container lip is inserted into the channel and the ridge to move inwardly toward the outside wall of the container below the lip when the lid is in sealing position over the top of the container, the interaction of the ridge and lip tending to secure the lid to the container over the open top of the container;
• an inner bead extending from the second cylindrical wall into the channel, said bead having a normal outside diameter larger than the inside diameter of the open container at a location along the inside wall of the container contacted by the inner bead when the lid is in sealing position over the top of the open container;
• and
• a central lid portion secured to the second cylindrical wall and closing the area inside the second cylindrical wall, said central lid portion including a third cylindrical wall and a web joining the third cylindrical wall to the second cylindrical wall, the web position and orientation with respect to the second and third cylindrical walls being deformable as the lid is placed in sealing position over the open topped container to allow the inner bead to move inwardly and the receiving channel to receive the top of the container and to apply sealing pressure of the inner bead against the inside wall of the container when the lid is placed in sealing position over the open topped container;
• a discharge opening in the central lid portion for discharge of liquid from the container so that a user can drink from the container with the lid in sealing position over the container;
• and
• a spout aligned with the discharge opening to aid the user in aligning the discharge opening with the user's mouth.

• an inner bead extending from the second cylindrical wall into the channel, said bead having a normal outside diameter larger than the inside diameter of the open container at a location along the inside wall of the container contacted by the inner bead when the lid is in sealing position over the top of the open container;
• and
• a central lid portion secured to the second cylindrical wall and closing the area inside the second cylindrical wall, said central lid portion including a third cylindrical wall which forms a reservoir, and a web joining the third cylindrical wall to the second cylindrical wall, wherein the third cylindrical wall is displaced downwardly when the lid is placed in sealing position over the open topped container and the web is displaced at a downward angle with respect to the second cylindrical wall to allow the inner bead to apply sealing pressure against the inside wall of the container;
• and
• a discharge opening in the central lid portion for discharge of liquid from the container so that a user can drink from the container with the lid in sealing position over the container.
