Abstract: A drinking container configurable between a drinking configuration and a whistling configuration. The drinking container comprise a main portion defining a liquid receiving cavity and a whistling portion positioned below the main portion and operatively connected thereto. The whistling portion comprises a whistle and is translatable relative to the main portion to configure the drinking container between the drinking configuration and the whistling configuration. When the drinking container is configured in the drinking configuration, a section of the liquid receiving cavity is sealed and prevents fluid communication between the liquid receiving cavity and the whistle while allowing the liquid receiving cavity to hold a liquid therein When the drinking container is configured in the whistling configuration, the section of the liquid receiving cavity is unsealed and allows fluid communication between the liquid receiving cavity and the whistle.

Abstract: A vessel adapted to hold a liquid and having a top portion and bottom portion, the top portion having an opening adapted for the injection of and the removal of the liquid, the bottom portion having an opening including threads. A whistle member capable of producing a whistling sound, the whistle member including threads adapted to be removably attached to the opening of the bottom portion of the vessel by interacting with the threads of the opening, such that after the liquid is removed from the vessel the whistle can be removed from the bottom portion and used to produce whistling sounds.
