Overview

The THERMOS FUNtainer 12oz is a stainless-steel, vacuum-insulated kids bottle designed for everyday school, daycare and short-trip use. At 12 ounces (≈355 mL), it’s sized for preschoolers through early-elementary children who need a compact, easy-to-carry bottle that still holds a useful amount of water. Double-wall vacuum insulation keeps drinks cold for up to 12 hours while the durable stainless-steel construction stands up to drops and rough play. The removable silicone straw with a hygienic flip cover and a soft-touch integrated carry handle make it easy and sanitary for kids to use. The bottle is BPA-free and dishwasher-safe, though the lid and straw are best cleaned by hand. Not for hot liquids.

Key Features

  • Capacity: 12 ounces (≈355 mL) — compact for backpacks and lunchboxes.
  • Insulation: Double-wall vacuum insulated stainless steel keeps cold drinks up to 12 hours.
  • Drinking system: Removable silicone straw with a hygienic flip cover to protect the mouthpiece.
  • Carry & durability: Integrated soft-touch handle and rugged stainless-steel construction built for kids.
  • Care & safety: BPA-free materials; bottle is dishwasher-safe (hand wash recommended for lid and straw to preserve seals and silicone).

Pros & Cons

Pros

  • Keeps drinks cold up to 12 hours thanks to double-wall vacuum insulation.
  • Durable stainless-steel body resists dents and stands up to typical kid wear-and-tear.
  • Compact 12 oz (≈355 mL) size tailored to small hands and lunchboxes.
  • Hygienic flip cover over a removable silicone straw reduces germ exposure.
  • Integrated soft-touch carry handle makes it easy for kids to carry independently.

Cons

  • Not intended for hot liquids, so it’s not suitable for warm beverages.
  • 12 oz capacity may be too small for older kids or long days without refills.
  • Straw and lid have small parts that require thorough cleaning and can retain moisture if not dried properly.
  • Although the bottle itself is dishwasher-safe, THERMOS recommends hand washing the lid and straw for longevity.

Recommendations

  • Preschool and early elementary students who need a lightweight, easy-to-hold water bottle for school or daycare.
  • Families who want a durable, insulated bottle for short car trips, playground outings, and field trips.
  • Parents who prioritize hygiene — the flip cover and removable straw make daily cleaning and protection easier.
  • Caregivers looking for a spill-resistant, insulated option that’s easier for small hands to manage than adult-sized bottles.

Frequently Asked Questions

No. The FUNtainer 12oz is designed for cold beverages only. The straw lid and flip cover are not intended for hot liquids and using hot drinks could damage components or create pressure build-up.
