Collection: Stainless Steel Food Jars

Why Stainless Steel Food Jars

High-quality stainless steel resists odors and stains, while vacuum insulation minimizes heat transfer so meals stay at safe, enjoyable temperatures. Whether you pack hearty chili, ramen, overnight oats, or fruit and yogurt, an insulated jar offers convenient portability with fewer spills. With Preply’s curated selection, you get practical capacities, user-friendly lids, and rugged builds that fit modern, on-the-go lifestyles.

Key Features to Look For

• Double-wall vacuum insulation to hold heat or cold for hours.
• Leak-resistant lids with silicone gaskets for confident carry.
• Wide-mouth openings for easy filling, eating, and cleaning.
• BPA-free components in contact surfaces and gaskets.
• Condensation control to keep exteriors dry in cold use.
• Portable capacities (10–24 oz) for kids, commuters, and hikers.
• Integrated utensil storage or nesting lids (select models).

Use Cases

Work & Commute: Pack soup, stew, curry, or pasta to avoid takeout and manage portions. School & Campus: Prep mac and cheese, dumplings, fried rice, or porridge in durable jars kids and students can open easily. Outdoors & Travel: Keep oatmeal hot for trailheads or chilled fruit for beach days without bulky coolers.

Pairing with Other Collections

For full-day carry, combine jars with Everyday Daypacks or Classic Lunch Totes that include upright bottle sleeves. Use Bento Box Carriers for sides and snacks, and add Reusable Ice Packs when packing cold items. Organize cutlery and napkins in compact Boxes & Bags to keep lids and spoons clean.

Packing & Temperature Tips

1. Pre-heat or pre-chill: Fill the jar with hot water for 5 minutes (hot foods) or ice water (cold foods), then empty and load.
2. Fill efficiently: Leave a small headspace so the lid seals without pressure buildup.
3. Layer smart: Dense items like grains or noodles at the bottom; broths or sauces on top.
4. Seal promptly: Close the lid right after filling to reduce heat loss or warming.
5. Check tightness: Ensure the gasket is seated; avoid overtightening to protect threads.

Care & Cleaning

Rinse after use and wash with mild soap; use a soft bottle brush for the interior and lid channels. Remove silicone gaskets periodically to clean residue under the seal and air-dry fully. Avoid bleach or abrasive pads that can damage finishes. For lingering aromas, soak with warm water and baking soda, then rinse thoroughly.

Size & Capacity Guide

• 10–12 oz (Kids/Light Meals): Great for yogurt, oatmeal, or side soups.
• 14–16 oz (Daily Standard): Most versatile for single-serve soups, pasta, or rice bowls.
• 18–24 oz (Hearty/Full Meal): Extra space for stews, substantial grains, or layered salads.

How to Choose

1. Match your meals: Soup lovers may prefer taller profiles; mixed bowls suit wider jars.
2. Lid design: Select simple twist lids for reliability; consider vented caps for steam release.
3. Grip & carry: Look for textured exteriors or handles if you open jars on the move.
4. Jar diameter: Ensure it fits your lunch bag or side pocket upright.
5. Maintenance ease: Fewer parts and wide mouths speed cleaning and drying.

FAQs

How long do jars keep food hot or cold?
Performance varies by capacity and insulation, but many maintain temperature for several hours when pre-heated or pre-chilled.

Are the lids leakproof?
Most lids are leak-resistant with silicone gaskets; use sealed containers for thin liquids if carrying horizontally.

Can I put jars in the dishwasher?
Many bodies are top-rack dishwasher safe; hand-wash lids and gaskets for longevity. Check individual product care notes.
