FAQ
Frequently Asked Questions
Q: What is the capacity of this food jar, and is it suitable for a typical lunch portion?
A: This food jar has a 400ml (approximately 13.5 oz) capacity, which is ideal for a single serving of soup, stew, rice with side dishes, or leftovers. It is well-suited for an average adult lunch portion, but may be small for very large appetites. We recommend using it for soups, porridge, or small meals.
Q: How long does the vacuum insulation keep food hot or cold?
A: The double-wall vacuum insulation can keep hot food above 60°C (140°F) for up to 6 hours and cold food below 10°C (50°F) for up to 6-8 hours, depending on the initial temperature of the food, the ambient temperature, and how often the lid is opened. Pre-heating the jar with hot water or pre-cooling it with cold water before filling will maximize performance.
Q: Is the stainless steel food-safe and dishwasher safe?
A: Yes, the interior and exterior are made of high-quality 304 stainless steel, which is food-grade, BPA-free, and rust-resistant. The jar is not recommended for dishwasher use as prolonged high heat may damage the vacuum seal. Hand washing with warm soapy water and a soft sponge is recommended for longevity.
Q: Is the lid leak-proof? Can I carry it in my bag without spilling?
A: The lid is designed with a silicone sealing gasket to prevent leaks when tightly closed. It is not intended for carbonated or extremely liquid-thin foods without caution. For best results, ensure the lid is fully screwed on and avoid overfilling. It is safe to carry upright in a bag for most semi-liquid foods like soup, but for very watery contents, we recommend storing it upright.
Q: Can I use this container for both hot and cold foods?
A: Absolutely. The vacuum insulation works both ways: it keeps hot foods hot and cold foods cold. It is perfect for hot soup, pasta, or rice, as well as cold salads, fruit, yogurt, or even ice cream. Just remember not to microwave or freeze the jar itself, as that can damage the vacuum layer.
Q: What is the warranty policy for this product?
A: This product comes with a 12-month limited warranty against manufacturing defects, such as vacuum failure or lid malfunction. Normal wear and tear, dents from drops, or damage from improper cleaning are not covered. If you experience any issues, please contact our customer service with your order number for a replacement or refund.
Q: What are the external dimensions and weight of this food jar?
A: The jar has a diameter of approximately 9 cm (3.5 inches) and a height of about 14 cm (5.5 inches). It weighs roughly 300 grams (10.5 ounces), making it compact and lightweight enough to fit in most standard lunch bags or backpacks.
Q: Do you offer custom printing or logo options for bulk orders?
A: Yes, for bulk or wholesale orders, we offer customization options including laser engraving or screen printing of your logo or design. Minimum order quantities apply. Please contact our sales team with your requirements for a quote and lead time.

Usage Instructions & Precautions
How to Use and Maintain Your Food Jar
- Pre-heating/Pre-cooling: For best thermal performance, fill the jar with boiling hot water (for hot foods) or ice cold water (for cold foods) and let it sit for 5 minutes before emptying and adding your food.
- Filling: Do not overfill; leave a small gap at the top to allow the lid to seal properly. Ensure the lid is screwed on tightly.
- Cleaning: Hand wash only with warm water and mild detergent. Use a soft sponge to avoid scratches. Rinse thoroughly and dry upside down with the lid off. Never use abrasive cleaners or bleach.
- Do NOT: Microwave, put in freezer, or use in dishwasher (prolonged heat can damage vacuum seal). Avoid dropping or hitting the jar harshly as dents can affect insulation.
- Storage: Store with the lid off or loosely placed to allow air circulation and prevent odors.
- Safety: Always check the temperature of food before serving, especially when heating to avoid burns. The outer surface may become warm when containing hot food, but not hot enough to harm.
- Leak Prevention: Ensure the silicone gasket is clean and properly seated. Do not use for carbonated beverages as pressure may cause leakage.
