Lunchbox Range Design & Development · Newell Brands - Sistema, NZ · 2024–26
Heatables
Microwave safe food containers
End-to-end NPD lead for a $40M USD revenue target (3 YR) — from consumer research and product strategy through to launch-ready SKUs already on shelves at select ANZ retailers, with full launch across ANZ, NA, and EMEA by June 2026. Co-inventor of a patent-pending lever mechanism that solved a critical usability-performance trade-off in leakproof lunchbox design.
Project Summary
Problem
No leakproof, microwave-safe adult lunchbox in the Sistema range.
My Role
End-to-end NPD lead — research, concept, IP, design, and launch as the technical and design resource across 5 functions.
Outcome
8 SKUs, $40M USD target, 90%+ consumer validation, 1 patent co-invented.
Research & Analysis
User Research
Target Demographic: Adults in the workforce — men and women, ages 26–60
Research Approach
A mixed-methods research strategy was employed to ground the design brief in real consumer behaviour and market context.
A. Market Visits
Retail audits across six Auckland stores assessed the existing lunchbox landscape, price positioning, and competitive shelf presence for the adult segment:
- Woolworths
- Farmers
- Pak'nSave
- Two Dollar Store
- Typo
- Briscoes
Competitive Landscape
Primary competition in ANZ: Decor. Sistema's existing range had been widely copied by private label brands — eroding shelf differentiation and shifting the brief from incremental improvement to IP-protected innovation.

Questionnaire Findings
How adults actually lunch
Beyond ranking features, the questionnaire surfaced four behavioural patterns that directly shaped the design brief — what people eat, how much they pack, whether they reheat, and how they store their food at work.
Q What do you generally have in your lunchbox?
Q Do you generally heat your meals in the microwave?
Q How many items do you pack for lunch generally?
Q Do you store your lunchbox in the workplace refrigerator?
Consumer questionnaire insights — n=48
48% answered Bowl / Container type — 90% also preferred warm meals
58% answered Yup (store in fridge) — 89% also preferred warm meals
34% answered 15–30 mins prep time — 91% also preferred warm meals
64% answered 1 to 2 items packed — 95% also preferred warm meals
Cross-question correlation — majority who selected each option also preferred warm meals (Q5)

Insight & Ideation
From insight to concept
Research findings directly informed the concept direction — an adult-first lunchbox range engineered around portion control, leakproof performance, and modular flexibility for the modern workday.
User research and secondary analysis of existing leakproof bento products revealed a critical friction point: while the wiper seal delivered strong leakproof performance, it significantly compromised the opening experience — making the lunchbox unnecessarily difficult to use day-to-day.
The design challenge became clear: solve for usability without sacrificing performance.
Concept Exploration
Ideation
Three concept directions were developed as low-fidelity CAD models to communicate the initial idea: a 2-shot injection moulding process with a live hinge in polypropylene. The three directions — Bold, Bolder, and Boldest — explored progressive levels of form confidence, from a minimal enclosed profile to a more expressive, divided container architecture.
Following technical review with Engineering teams — and drawing on experience from previous live hinge products in the range — it was determined that a PP live hinge carries a high fail rate under repetitive microwave heat cycling. The project direction then pivoted to a separate-part lid and base, opening the path to a 3-shot tooling solution and the clip mechanism that became the defining innovation of the range.

Mechanism Design
The lever clip — Core Product Detail
The integrated lever is moulded directly into the clip body — eliminating any separate component while reducing the opening force required.
IP-protected by design — the lever mechanism patent creates a competitive moat private-label brands cannot cross. Differentiation is functional, not just aesthetic.

Patent-pending lever clip — CAD cross-section showing pivot geometry
Multiple ideation rounds explored ways to reduce the effort required to open the seal. The winning solution was an integrated lever feature on the lift mechanism — a simple, intuitive addition that makes the lunchbox effortless to open while fully maintaining its leakproof integrity and passing all required performance testing qualifications.
Patent-pending co-invention — the integrated lever lift mechanism is filed with Sistema's Legal and Regulatory teams, with Shruti named as co-inventor.
Range Design
Design intentions across the range
Each product in the range was designed around a specific use occasion — the clip mechanism for everyday leakproof carry, round formats for portion-controlled nesting and compact storage, and the steamer insert for hot meal preparation at the desk.
Lever clip — leakproof carry, easy open
Round nesting 2-pack — compact storage
Steamer insert — hot meal prep, microwave-ready
Product Design
Features engineered around the brief
Every feature traces back to a research finding — from the wiper seal's leakproof performance to the microwave-safe base, the integrated handle, and the clip mechanism that resolves the usability-performance tension.
Prototyping
SLA prototypes — validating form and fit
High-fidelity SLA prototypes were produced to validate final form language, clip ergonomics, and stacking configuration ahead of tooling sign-off. Prototypes were reviewed with R&D, CMF, and Manufacturing teams as part of the stage-gate process.
Two design changes surfaced through SLA review and tooling evaluation:
- PP rib added to clip interior — ensures TPE overmould fills cleanly and consistently during the 3-shot process
- Wall added to external clip face — conceals hinge detail, improves tooling quality, and created a dedicated logo zone for planogram presence when the product faces sideways in pack
CMF
Colour, material & finish
The three colourways — teal, navy, and purple — sit within the broader colour categories standard to Sistema and the food storage category, selected specifically for their appeal to the adult demographic.
A key CMF insight shaped the colour application strategy: microwave use with food items such as tomato-based sauces causes discolouration on internal PP surfaces. While harmless, this staining renders the container visually unpleasant well before the end of its functional lifespan. To mitigate this, the PP substrate was specified in a darker tint to absorb staining without showing it, while the TPE overmould was applied in the lighter tint — preserving the fresh, two-tone aesthetic that defines the range. This decision was made in collaboration with the CMF team; the discolouration insight was a direct contribution from Shruti as design lead.

Dark tint — PP base & clip body
Light tint — TPE overmould
Navy

Purple

Each colourway applies the darker tint to PP and the lighter tint to TPE — a functional CMF decision to manage microwave staining over product lifespan

Design for Manufacturing
Technical Specifications
Manufacturing Approach
The MicroBento clip is produced using a 3-shot injection moulding process — a single tool that sequences three materials in one cycle, eliminating assembly labour and reducing component count.
Shot 1 — PP base: Coloured PP forms the base body.
Shot 2 — PP Lid: Clear PP fills lid cavities. Part thickness is high at 2.5mm to reduce deformation through repeated microwave use.
Shot 3 — TPE Base and Seal: TPE overmoulds on PP base and forms the leakproof wiper seal on the lid.
All materials are food-contact compliant — PP and TPE grades specified to meet FDA and EU food-safety regulations.
Stage-gate outcome: The TPE sleeve was originally specified to support an insulated safe-hold feature claim. Performance testing did not validate sufficient thermal insulation, so the feature claim was reduced to non-slip base only — a direct result of stage-gate qualification.

Reflections
What I'd do differently
If running this programme again, I would bring Manufacturing into the ideation phase earlier — the 3-shot tooling decision was made mid-development and, while it proved to be the right call, earlier manufacturing input would have reduced iteration cycles on the clip geometry. I would also expand the primary research sample and geographic spread beyond Auckland; the 63-person questionnaire was directionally strong but a broader, multi-market dataset would have given the brief greater rigour at senior stakeholder review.
The pivot from aesthetic differentiation to IP-protected design was the most consequential decision on this project — and it came from directly using the existing product, observing its shortcomings first-hand, and recognising that the real gap was in the product experience, not just aesthetic. That's a lesson I carry forward: the most important strategic insights often surface through hands-on experience in the field, not in the boardroom.
