Use & Care

Lid Attachment

Make sure the lid is perfectly aligned with the screw thread. For optimal seal twist until indicators on lid and tumbler are aligned.

Condensation

My First Tervis™ sippy cup is double-wall insulated and will prevent condensation from forming under most conditions. However, on very humid days you may experience a small amount of condensation.

Hot Liquids

My First Tervis™ sippy cup can hold hot liquids, but we do not recommend microwaving liquid as it could burn your child. We recommend testing liquid temperature before giving to child. If you do warm liquids with a microwave, the My First Tervis™ sippy cup lid must be removed for safety.

Cold Liquids

You can refrigerate the My First Tervis™ sippy cup.

NOTE: We do not recommend using ice in My First Tervis™ sippy cup.

Carbonated and Pulpy Beverages

Carbonated beverages can generate pressure inside the My First Tervis™ sippy cup and may cause it to leak. Our sippy cup is not intended for carbonated or pulpy beverages. These types of beverages may impede performance of the lid valve. The My First Tervis™ sippy cup is intended for non-carbonated drinks such as water, milk and pulp-free juice.

Dishwasher & Cleaning

The My First Tervis™ sippy cup and lid are dishwasher safe, top rack only. There is no need to remove internal o-ring (silicone ring on lid) for normal cleaning.

Valve must be removed from lid for proper dishwasher cleaning. A loop on the valve allows you to attach it to a lid handle to help prevent the valve from being lost or damaged during cleaning.

Removal & Reinsertion of Valve

To remove the valve, unscrew lid from My First Tervis™ sippy cup and pull out valve.

To insert valve, press firmly with finger until the valve is completely seated in top and bottom slots.

Removal & Reinsertion of O-Ring (not required for everyday cleaning)

To remove the o-ring, unscrew lid from My First Tervis™ sippy cup. Place the lid in one hand and with your other hand, pinch the o-ring between your finger and thumb and pull out. Please use care not to over stretch o-ring.

To insert the o-ring, press firmly with finger until the o-ring is completely seated in groove.

Do not place in dishwasher. Only use mild dish detergent and a non-abrasive sponge or cloth. Rinse with water and towel dry.

Do not store near heat sources, including stovetop, oven, radiator, heat vents or leave outdoors for an extended period of time. Exposure to excessive heat may damage the ice bucket.

Do not place in microwave.

The Legacy Classic Water Bottle is intended for cold non-carbonated drinks. Hot liquids and carbonated beverages generate pressure inside the water bottle that may cause it to leak.

If the water bottle is leaking, make sure that the gasket is correctly placed in the lid and that your water bottle lid is securely fastened to the water bottle.

The water bottle and lid are dishwasher safe, top rack only. Do not remove internal gasket (silicone ring inside lid) for normal cleaning.

Removal & reinsertion of gasket

To remove the gasket, unscrew lid from water bottle, open lid and pull back into a locked position. Repeatedly tap base of lid on flat surface until gasket comes loose.

To insert gasket, press firmly with finger until gasket is completely seated in groove.

Lid Application

Make sure the lid is perfectly aligned with the bottle screw thread before securely fastening it to the water bottle. This can be achieved by either lining up the lid latch to the emblem on front, or the ounces on back, depending on which way you prefer the emblem to be facing when drinking, then screwing the lid on tightly.
