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

The DeliOne Flex'n Jar — Winner of the Red Dot Design Award. Featuring a one-press collapse and one-pull expansion mechanism, this jar adjusts to any height without preset creases. Crafted from premium Japanese platinum food-grade silicone, it lets you push out excess air to slow oxidation and can be turned inside out for thorough cleaning. Reusable over 5,000 times, it’s time to say goodbye to disposable plastic containers.

Built on the core concept of "Less Air, More Freshness," the DeliOne Flex'n Jar has completely reimagined food storage. The body is made from Japanese platinum food-grade silicone, providing both flexibility and resilience; it collapses in a second with a gentle press and expands instantly with a light pull. Unique to its design, the jar has no fixed creases, allowing it to compress to the precise height of your food. When paired with the airtight lid, it squeezes out excess air, reducing contact with oxygen—keeping crackers crunchier, nuts fresher, and coffee beans more aromatic. As you consume the contents, the jar shrinks along with them, maximizing your cupboard and fridge space. The soft body can even be inverted, allowing you to flip the inner walls out for direct rinsing—a deep-clean capability impossible with glass or hard plastic jars. BPA-free and heat-resistant up to 220°C, it is safe for everything from the freezer to the microwave and dishwasher. From breakfast cereal to microwave lunches, afternoon snacks, and grocery shopping, it’s the one jar for your entire day.

Do you face these common struggles?

• Opening a large jar of crackers, nuts, or cereal only to have the contents soften and lose freshness as you finish them, due to the excess air inside.
• Kitchen cupboards and fridges always feeling crowded with half-empty storage containers.
• Heavy, fragile glass jars or hard plastic containers with hard-to-clean corners that trap odors and oil stains.
• Relying on disposable plastic bags and boxes for takeaway or groceries, despite knowing it's not environmentally friendly.
• Needing a container for travel or camping that won't take up space or remain bulky after use.

Why choose the DeliOne Flex'n Jar?

Most foldable containers on the market feature one or two fixed creases, limiting them to just "fully open" or "fully collapsed," with no adjustment for partial portions. Many are made from low-quality silicone or mixed plastics, prone to white stress marks, cracking, or retaining a chemical odor. The DeliOne Flex'n Jar uses a patented Red Dot Design Award-winning structure to provide infinite height adjustment, one-second transformation, and true volume compression based on food quantity to remove air. Featuring Japanese platinum food-grade silicone (80% non-fossil based raw material), it is flexible, durable, neutral in taste, and BPA-free. Designed for over 5,000 reuses and fully reversible for cleaning, its hygiene far surpasses any hard container. This is not just a container—it is a smarter, more sustainable way to preserve your food.

Three Key Features

1. One-Second Transformation × Infinitely Adjustable Compression

Collapse with a light touch and expand with a quick pull—all in under a second. Designed without preset creases, it compresses to any height based on the remaining food volume, saving space instantly.

2. Vacuum Compression × Minimum Air, Maximum Freshness

By compressing the jar to expel air before sealing the lid, you drastically reduce food oxidation and moisture absorption. Keep your crackers crispy, nuts and coffee beans fragrant, and fruits and vegetables fresh for longer.

3. Reversible Cleaning × No Hidden Corners

The flexible silicone body can be turned completely inside out, allowing for direct rinsing of the inner walls, bottom, and folds. It's dishwasher-safe and ensures no residue or odors remain—a level of cleanliness glass and plastic simply cannot reach.

Instructions for Use

Pro Tips

• For dry goods (crackers, cereal, nuts), compress and expel air every time you finish serving to maintain peak crispness.
• When storing liquids, compress the jar to the desired height before pouring to avoid spills.
• Use it to make oatmeal or mix hot drinks: seal the lid and shake to mix—no spoon required.
• Ensure the jar is completely dry before collapsing for storage. Flat stacking saves space and prevents odors.
• Great for work lunches: compress to save space in your bag and minimize spills.

Precautions

• When microwaving, open or loosen the lid to prevent steam pressure buildup; do not expose the lid to high heat for extended periods.
• Do not place in direct contact with flames, stove tops, or heating elements. Maintain temperature under 220°C.
• Do not use sharp objects, hard brushes, or steel wool to clean, as these may scratch the silicone.
• When holding hot liquids, handle with care as the silicone is flexible; use the base to support it and watch for steam when opening.
• Dark-colored sauces (curry, ketchup) may cause slight staining over long periods, which does not affect function. Wash as soon as possible.
• Wash before and after each use. Discontinue use if the jar or lid becomes damaged.
• Keep out of reach of children.
