ThermoFlask insulated 20 oz food jars 2-pack — Pink & Blue, vacuum-sealed, leak-resistant (Hot 12H / Cold 24H)

ThermoFlask 20 oz Insulated Food Jars (two-pack) are stainless-steel containers engineered to keep meals hot up to 12 hours or cold up to 24 hours while remaining leak-resistant and easy to carry.

If you pack lunches, bring soups to work, or want chilled snacks for day trips, these ThermoFlask jars deliver dependable temperature control in a compact, everyday size. This two-pack includes two 20-ounce jars finished in complementary colors so you can separate meals, share with a family member, or alternate uses. Each jar pairs vacuum insulation with a screw-top lid and practical details designed for routine use at home, school, or outdoors.

How long will food stay hot or cold in these jars?

ThermoFlask uses double-wall vacuum insulation and Temp-Lock technology to slow heat exchange. Expect warm foods to stay hot for up to 12 hours and chilled items to remain cold for as long as 24 hours under normal conditions.

• 12 hours of heat retention for soups, stews, and hot casseroles
• 24 hours of cold retention for salads, yogurt, and fruit
• Consistent results depend on initial food temperature and ambient conditions

Are these jars leakproof and easy to transport?

Yes—each jar features a screw-on lid engineered to create a tight seal, reducing spills when placed inside backpacks or lunch bags. An integrated handle makes it simple to carry, and a silicone base prevents slipping and protects surfaces.

• Screw-top lid for a secure, leak-resistant closure
• Easy-grip handle for one-handed carrying
• Non-slip silicone base to stabilize jars on tables and counters

What materials and care instructions should I know?

These food jars are constructed from 18/8 food-grade stainless steel with a durable powder-coat exterior that resists chips and maintains grip. They are BPA-free and designed to avoid flavor transfer. For cleaning convenience, they are dishwasher-safe, though hand washing will extend finish longevity.

• 18/8 stainless steel interior for neutral taste and durability
• Powder-coated exterior in pink and blue for wear resistance and aesthetics
• Dishwasher-safe, BPA-free, and backed by a limited lifetime warranty

What meals fit best in a 20 oz jar and how can I use the two-pack?

A 20-ounce capacity is versatile for single-serve portions like soups, grain bowls, oatmeal, and chilled fruit or salads. The two-pack lets you prep different meals at once or keep an alternate dish cool while enjoying a hot entrée.

• Portion soups, stews, and chili for lunch or travel
• Store overnight oats, salads, or cold desserts without sogginess
• Use one jar for hot items and the other for cold to maintain meal balance

Who is this for? These ThermoFlask 20 oz jars suit commuters, parents packing lunches, students, and outdoor enthusiasts who need reliable temperature control without bulky containers. They’re ideal when you want separate portions, simple cleaning, and a durable build that travels well in backpacks, tote bags, or picnic baskets. If you prioritize leak resistance, neutral flavor retention, and a compact size that accommodates a full meal, this two-pack offers practical daily performance and color-coded convenience.
