Great Lids for Even Greater Coffee
01 · The Opportunity
Great coffee, not so great lids
Qahwa BLK put a lot of effort into roasting, brewing and serving high‑quality coffee. But one improvement opportunity kept showing up in daily operations and customer feedback: leaking plastic lids.
During barista prep, delivery runs, and in customers’ cars, lids would occasionally pop, drip, or simply not seal well enough, costing time, good coffee, and a bit of trust with each spill.
- Complaints from delivery drivers and customers about leaking drinks
- Extra time spent double‑checking lids or re‑preparing orders
- Using two lids for one cup - doubling the consumption of BLK's lids
02 · The RZ Solution
Engineering a tight, reliable lid–cup system
RZ were adamant to find a solution in make the coffee drinking experience pleasant for both offering and enjoying parties.
RZ worked to develop the lid until they reached the desired outcome: a lid that clicks firmly into place, stays sealed when drinks are carried or transported, and still feels comfortable to drink from. Multiple samples were tested in store - shaken, stacked, delivered - ensuring no Qahwa BLK coffee was spilled.
- Careful fit testing between lids and existing cup sizes and materials
- Ongoing supply of the approved non‑leaking lids through RZ as a single vendor
03 · Results & Impact
No spills, stronger customer confidence
Since switching to the new lids developed by RZ, Qahwa BLK has seen a dramatic drop in complaints related to leaking drinks. Staff now spend less time re‑preparing orders, use a single lid for a single cup (as should be), and delivery partners feel more confident transporting full trays of coffee.
For customers, the change is simple but powerful: their drink is enjoyed the way it should — intact and without mess. For Qahwa BLK, this small packaging upgrade supports the bigger promise of quality in every cup.
- Near‑zero leak incidents reported after rollout of the new lids
- Smoother operations with fewer remakes and less waste
- Better to-go and delivery experiences
