STL BIG BITE 4
- Model: LEAKPROOF
- JAN: 358
Five containers.
Every course, covered.
The Big Bite 5 rounds out the Nutri-Lock lineup with five stainless steel containers at graduated sizes, from a 300ml side to a 570ml salad dabba — enough range to pack a genuinely complete meal in one insulated pouch.
Five sizes, one complete meal.
Two full-size mains, a side, and a genuinely sized salad dabba — sized to cover a whole plate, not just one dish.
What the construction says about how long this lasts.
Five pieces at different sizes puts more variety of demand on the seal and the steel — here's how it holds up.
Steel sized for a full plate
Two 450ml containers cover the mains — a curry and a rice or noodle dish — while the 300ml container handles a lighter side. The two 570ml pieces, one main-sized and one the salad dabba, mean this set can carry a genuinely complete meal rather than a single dish stretched across smaller compartments.
Every container is food-grade stainless steel with a mirror-finished interior, resisting stains from oil and turmeric and making daily cleaning fast across five separate pieces.
A seal that scales with the set
With five containers of varying sizes, consistency in the seal matters more, not less. The molded stainless steel lid and 180-degree clip design apply the same closing pressure regardless of container size, so the leak-proof, air-tight seal holds whether it's the 300ml side or the 570ml main.
The soft carry pouch is built to carry the combined weight of all five pieces without sagging, while its insulation keeps the largest containers just as warm as the smallest.
What makes up the Big Bite 5.
Five graduated steel containers
Two 450ml, one 300ml, and one 570ml container, plus a 570ml salad dabba — enough range to plate a full meal.
100% leak-proof, air-tight seal
Every container holds a genuinely air-tight seal, keeping gravies, rice, and liquids contained through the whole commute.
Molded stainless steel lids
Durable, warp-resistant lids that hold their seal and shape well beyond a single season of daily use.
180° detachable clip lock
A single clip rotation opens or seals each container — fast, one-handed, and consistent across all five pieces.
570ml salad / side dabba
A genuinely large bonus container — big enough for a proper salad or a full side, not just a garnish portion.
Dual-tone navy & sky blue finish
A cohesive, elegant colourway across all five pieces, distinguishing containers at a glance while looking considered as a set.
Mirror-finished interiors
A polished steel interior on every container, simplifying cleaning and keeping the set hygienic across daily use.
Food-grade, rust-free steel
Built to outlast disposable containers entirely, with no rusting or degradation even under daily hot-food contact.
Insulated soft carry pouch
A structured pouch that holds its shape under the combined weight of five containers while keeping food warmer for longer.
BPA-free construction
Every plastic element, including the salad dabba, is BPA-free — food safety built in rather than bolted on.
Built for a complete plate, not one dish.
Five containers at different sizes opens up more than a standard tiffin can cover.
Mains, side, and salad
Two 450ml mains, a 300ml side, and a proper salad dabba — a complete plate rather than a single-dish lunch.
Two people, five containers
The spread of sizes makes it easy to split between two people, each getting a main, a side, and a share of the salad.
A full day, pre-portioned
Five sealed containers make it simple to portion an entire day's meals the night before, each dish kept separate.
A dedicated salad course
The 570ml salad dabba is large enough to carry an actual salad as a full component of the meal.
Picnics & day trips
Enough total volume across five pieces to cover a family picnic, with the insulated pouch holding temperature throughout.
Beyond just lunch
At home, the five containers double as fridge-safe storage for leftovers in a range of portion sizes.
What arrives in the pouch.
Big Bite 5 vs. Big Bite 4.
The step up from four to five containers adds real range, not just an extra piece.
| Aspect | Big Bite 5 | Big Bite 4 |
|---|---|---|
| Total containers | 5 steel pieces + range from 300–570ml | 4 steel pieces + range from 300–450ml |
| Largest container | 570ml main + 570ml salad dabba | 450ml main + 570ml salad dabba |
| Best suited for | A full plated meal or two people sharing | A generous single-person meal |
| Seal | 100% leak-proof across all five | 100% leak-proof across all four |
Care that protects the seal across five pieces.
More containers in rotation means the basics matter a bit more, not less.
Hand wash the lids
The clip mechanism lasts longest away from repeated dishwasher heat — warm water and mild soap by hand is safest across all five.
Dry fully before sealing
Air-dry every container and lid before closing for storage — trapped moisture is the main cause of lingering odour in steel.
Skip the steel wool
A soft sponge keeps the mirror finish intact across every container; abrasive scrubbers dull the polish over time.
Spot-clean the pouch
Wipe the exterior fabric rather than soaking it — this preserves the insulation and shape of the pouch under the combined load.
Fill hot, not boiling
Warm food is what the seal and lid finish are designed around — very high heat repeatedly can stress the clip's grip over time.
Check all five clips
With five containers in daily rotation, run each 180° clip through its motion every few weeks to confirm the seal still holds.
The most complete plate in the Nutri-Lock range.
The Big Bite 5 covers a full meal's worth of range — two mains, a side, an extra main-sized container, and a real salad dabba, all sealed and insulated in one pack. It's built for the day the meal has more than one course.
