  • Patent number: 4925040
    Abstract: A child's canteen having a latched pivotally mounted cap on its top which when closed engages a spring-loaded tubular member which extends into the interior of the canteen. The cap normally holds the tubular member in a retracted position. However, when the latched cap is released, the tubular member pops up through the top of the canteen and causes the cap to swing open. The contents of the canteen may now be sucked through the tubular member.

  • Patent number: 4732303
    Abstract: A cover assembly for a thermos, or other bottle, which includes a dispensing spout which is movable between a closed and an open position. The dispensing spout has an opening extending through it which becomes aligned with an opening in the cover when the spout is turned to its open position. The spout also includes a vent which becomes aligned with a vent in the cover when the spout is in its open position. The opening and vent in the cover are both closed and sealed by the spout when the spout is turned down to its closed position. The spout is held in its open and closed positions by a snap-acting leaf spring element which causes the spout to be snapped to its open or closed position when the spout is turned manually in one direction or the other. The dispensing spout may be used either to pour the contents out of the bottle, or to receive a drinking straw into the interior of the bottle.
