Care and Use


Care and Use: FUNtainer™ Beverage Bottle


Before first use, and as soon as possible after each use, wash all parts with warm, soapy water.

Rinse thoroughly and allow to dry.

  • DO NOT use abrasive cleansers or scrubbers as they may dull the finish.
  • DO NOT use bleaches or cleaners containing chlorine on any parts of the product.

All parts are top rack dishwasher safe; however, hand washing is recommended for best results.

For maximum thermal efficiency, prechill beverage bottle prior to use. Fill with cold tap water, attach lid, let stand 5 to 10 minutes and empty.

This product is leak-proof only when the lid is in the closed and locked position.
