wiwens 32oz Thermo Food Jar — Wide-Mouth Vacuum Insulated Stainless Steel, Leakproof with Spoon

The wiwens 32oz Thermo Food Jar is a wide-mouth, double-wall vacuum insulated stainless steel lunch container that keeps hot food hot and cold food cold while staying leakproof and portable.

This insulated food jar combines a 32-ounce capacity with practical everyday features — a removable inner bowl for portioning, a hidden folding spoon, a leakproof silicone seal, and a non-slip base. Built from 18/8 food-grade stainless steel with a threaded lid and internal silicone ring, it’s designed to carry soups, stews, salads, and meal preps to school, work, or outdoor activities. Preheating or pre-chilling before filling improves temperature retention.

How long will this jar keep my soup hot or my salad cold?

The double-wall vacuum insulation maintains high temperatures for up to 6 hours and cold temperatures for up to 8 hours under normal conditions. Actual retention depends on initial food temperature, ambient conditions, and whether you preheat or pre-chill the jar.

• 6 hours of warmth for hot meals when preheated with hot water for 10–20 minutes.
• Up to 8 hours cold when chilled in the fridge for 10–20 minutes prior to filling.
• Wide mouth allows quick filling and faster cooling or reheating access.
• 18/8 stainless steel interior resists odor and flavor transfer.

Is the jar truly leakproof and easy to carry?

Yes — an internal silicone sealing ring combined with a threaded lid design creates a tight, leak-resistant closure. The lid also includes a discreet exhaust valve for safe opening after transporting warm meals.

• Threaded lid plus internal silicone ring for reliable leak protection.
• Exhaust valve releases pressure before opening hot containers.
• Hidden folding spoon stored inside the lid for convenience.
• Anti-slip silicone base prevents sliding or rolling on surfaces.

Can I separate different foods inside the container?

The jar includes an internal bowl compartment that helps keep components separate — ideal for soups with toppings, rice and curry, or entrees and sides. A silicone cover over the inner compartment adds another layer of spill protection.

• Removable inner bowl lets you portion and separate items.
• Silicone cover over inner compartment prevents cross-contamination and leaks.
• Wide opening makes scooping and washing simple and hygienic.

How do I get the best results and care for this food jar?

Preheat with hot water or pre-chill in the refrigerator for optimal temperature performance. Open the exhaust valve and let the jar sit five minutes before unscrewing the lid for easier opening when carrying hot foods. Hand washing is recommended to preserve seals and finish.

• Preheat: pour hot water in jar for 10–20 minutes before filling with hot food.
• Pre-chill: refrigerate the empty jar 10–20 minutes before using for cold meals.
• Always open the exhaust valve and wait five minutes to release pressure safely.
• Recommended age 3+; hand wash seals and inner bowl for longevity.
