SPILL-RESISTANT CONTAINER WITH REINFORCED COLD PLUG

摘要

A sippy cup (100) or other spill-resistant container including a cold plug (120) for cooling liquids placed therein. The sippy cup (100) includes a cup body (110) that surrounds a beverage storage chamber. A bottom wall (115) of the cup body (110) defines an opening. In one embodiment, a support flange (130) extends upward from the bottom wall (115) into the fluid storage chamber and surrounds the opening. In another embodiment, a support flange extends upward through the opening into the fluid storage chamber from a sleeved cap. The cold plug (120) structure includes a tube-shaped body (121) enclosing a refrigerant (125) and having a closed end that extends through the central opening into the fluid storage chamber. A base (127) of the cold plug structure is secured to the bottom wall of the cup body, and is supported by the support flange to prevent displacement of the cold plug caused by dropping or otherwise jarring the sippy cup.
