THERMOS Stainless King food jar 47oz, Matte Stainless Steel — vacuum-insulated, leak-resistant travel food container

The THERMOS Stainless King 47oz Food Jar is a heavy-duty, vacuum-insulated container that keeps meals hot up to 10 hours and cold up to 24 hours while remaining leak-resistant and travel-ready.

Whether you commute, hike, or need a reliable desk lunch solution, this matte stainless-steel food jar stores full meals and beverages with dependable temperature retention. Built with double-wall 18/8 stainless steel and Thermos vacuum insulation technology, the container includes two 20oz plastic inserts for portioning or sauces, a secure lid with pressure-relief stopper, and an ergonomic handle for carrying. It’s designed to be compact enough for backpacks and roomy enough to hold soups, stews, salads, or chilled treats without sweating or warming exterior surfaces.

How well does it preserve food temperature for a full day?

The Steel King uses vacuum-insulated double walls to minimize heat transfer, so hot foods stay hot for up to 10 hours and cold foods stay cold for up to 24 hours under normal conditions. Preheating or pre-chilling the jar before filling will improve performance for longer retention.

• Vacuum insulation for extended temperature control
• Hot retention: up to 10 hours (varies with ambient temperature)
• Cold retention: up to 24 hours for chilled meals and drinks
• Preheat/pre-chill step recommended for best results

What makes it practical for travel and outdoor use?

This food jar prioritizes portability and spill prevention: a leak-resistant lid secures contents, a pressure-relief stopper prevents messy eruptions, and a comfortable handle makes one-handed transport easier. The durable 18/8 stainless-steel shell resists dents and wear, and the exterior stays cool to the touch with hot contents and sweat-proof with cold ones.

• Leak-proof lid design when properly closed
• Pressure-relief stopper reduces spills during opening
• Wide-mouth opening for easy filling and eating on the go
• Lightweight yet rugged 18/8 stainless-steel construction

Can I portion meals or store different foods inside?

Yes. The jar includes two removable 20oz plastic containers that let you separate sauces, sides, or snacks from mains to avoid sogginess and make portioning simple. The wide-mouth design makes loading, scooping, and cleaning straightforward.

• Two included 20oz plastic inserts for portion control or condiments
• Wide opening accommodates bowls, ladles, and utensils
• Components disassemble easily for hand washing or top-rack dishwasher use
• Compact footprint fits most lunchboxes and backpacks

How do I clean and maintain the Thermos Stainless King?

The Stainless King disassembles for cleaning: remove inserts and lid parts, then wash by hand or place components on the top rack of a dishwasher as recommended. To maximize lifespan, rinse promptly after acidic or oily foods and occasionally preheat or pre-chill before use to preserve seal performance.

• Top-rack dishwasher safe for most parts (follow care instructions)
• Hand wash lid components and inserts if preferred
• Rinse promptly after use to prevent lingering odors or stains
• Preheat with boiling water for 5–10 minutes before filling hot meals
