Seat and snap-close lids on deli salad/dip containers
Reser's core retail products are deli salads and Stonemill Kitchens dips packed in rigid tubs that require a snap-fit lid to fully engage around the rim for a leak-proof, refrigerated-safe seal. Pressing and seating a lid uniformly around the perimeter so it clicks into full engagement is a contact task: the lid must align to the rim and the system must confirm the snap occurred all the way around, not just at the front edge. It sits at end-of-primary-packaging ahead of date coding and palletizing. Because an incompletely seated lid can leak or compromise refrigerated shelf life and food safety, undetected partial closures are costly. This is often machine-handled today, but per-container snap confirmation is where feel adds value. We identified this through our own research; we have not confirmed the specifics with the customer directly. This page is our researched read — a starting point for that conversation.

Is this the actual task and sequence? What are the real tolerances, cycle rate, and reject criteria, and which steps are today's manual bottleneck? Answering these is what turns this from a researched signal into a validated use case.
