Flexible Food Storage Jar | DeliOne Flex'n Jar from the USA

DeliOne Flex'n Jar (USA) – Winner of the Red Dot Design Award. Featuring a one-press collapsible and one-pull expandable design, it allows for height adjustment based on food quantity without fixed crease lines. Made from Japanese platinum food-grade silicone, it squeezes out excess air to slow oxidation and can be turned inside out for thorough cleaning. Reuse one jar over 5,000 times and say goodbye to disposable plastic containers forever.

Built on the core concept of "Less Air, More Freshness," the DeliOne Flex'n Jar completely reinvents food storage. The jar body is crafted from Japanese platinum-grade food silicone, which is supple and resilient, allowing it to collapse in a second with a gentle press and expand instantly with a light pull. Unique to this design, there are no fixed crease lines; you can compress it to match the exact height of the food inside. Combined with its airtight lid, it squeezes out excess air, reducing contact between food and oxygen—keeping cookies crisp, nuts fresh, and coffee bean aroma long-lasting. As you eat, the jar shrinks, maximizing space in your cupboards and fridge. The flexible body can be completely inverted for a direct, thorough wash, reaching crevices that glass or rigid plastic containers can't. The material is BPA-free, heat-resistant up to 220°C, and suitable for everything from the freezer to the microwave and dishwasher. From morning cereal and lunch leftovers to afternoon snacks and market groceries, one jar is your perfect companion all day long.

Do you struggle with these issues?

• Cookies, nuts, and cereals stored in large jars lose their freshness and turn soggy as the food level drops and air increases.
• Kitchen cupboards and fridges never have enough space, cluttered with bulky half-empty containers.
• Glass jars are heavy and fragile, while rigid plastic boxes are impossible to clean in corners and rims, trapping odors and oily residues.
• Relying on disposable plastic boxes and bags for takeout and shopping is wasteful, and finding better alternatives is difficult.
• Wanting to take food containers out, on trips, or camping, but finding rigid boxes bulky and impossible to downsize.

Why choose DeliOne Flex'n Jar?

Most collapsible containers on the market have fixed crease lines, limiting you to "full" or "collapsed" modes without middle-ground adjustment. Many are made from low-grade silicone or plastic blends that crack easily at fold lines or retain a plastic smell. DeliOne Flex'n Jar features a patented, award-winning structure that is creaseless, infinitely height-adjustable, and transforms in a second, truly adapting to your food volume while expelling air. Made with Japanese platinum food-grade silicone (80% non-fossil based), it is durable, neutral in flavor, and BPA-free. Designed for over 5,000 reuses and fully washable inside out, it offers hygiene levels far superior to any rigid container. This is not just a container; it's a smarter, more sustainable way to preserve your food.

Three Key Features

1. One-Second Transformation × Creaseless Infinite Compression

Collapses with a light press, expands with a light pull—all in a second. Expertly designed without fixed crease lines, it compresses to any height required. As your food level drops, your jar shrinks to match, saving every inch of space.

2. Airtight Air Extraction × Minimal Air for Maximum Freshness

After compressing the jar to push out excess air and securing the lid, you significantly reduce contact with oxygen, slowing down oxidation and moisture absorption. Keep cookies crisp, nuts and coffee beans aromatic, and fruits and vegetables fresher for longer.

3. Fully Invertible Cleaning × No Dead Corners

The flexible silicone body can be turned completely inside out, allowing you to wash the interior walls, base, and folds directly. No residue or odor is left behind, and it is dishwasher safe. Reach the corners that glass and plastic simply cannot with the Flex'n Jar.

How to Use

Pro-Tips

• For dry goods (cookies, cereal, nuts), compress and vent after each use to maintain maximum freshness.
• When storing soups or liquid-heavy foods, compress to the desired height before pouring to prevent spills.
• When preparing instant cereal or hot drinks, seal the lid and shake gently; no spoon needed!
• Ensure the jar is completely dry before collapsing and stacking for storage to save space and prevent odors.
• Perfect for packed lunches—compress, seal, and toss in your bag without worrying about leaks.

Usage Precautions

• Always open or loosen the lid before microwave heating to prevent steam pressure buildup; avoid prolonged heating of the lid.
• Do not use over an open flame, stovetop, or electric heating element; keep temperatures below 220°C.
• Do not use sharp objects, hard brushes, or steel wool to clean, as these may scratch the silicone.
• When storing hot drinks or soup, the silicone body is soft—hold the base steady when opening and be careful of steam.
• Deeply pigmented sauces (curry, tomato sauce) may cause slight staining over long periods, which does not affect function; wash promptly.
• Wash before first use and after every subsequent use; discontinue use if the jar is damaged or the lid becomes warped.
• Keep out of reach of children.
