A mint tin was Carol Vaziri’s first answer to the problem of carrying dog treats. In written answers for Debjo, the Piper Loop Pets co-founder recalled what bothered her about bags and pouches: “I hated carrying treats in a plastic bag or a pouch, because they’d always end up a crumbly mess.”
The container needed to fit into the places she already carried things. Vaziri described the goal this way: “I wanted something I could just grab and go, something that could live in my pocket, my purse, or the glove box.”
She said an engineer friend helped with prototypes as the idea moved toward a tin small enough for a pocket and sized for a walk or training session. The borrowed container also made one design problem clear.
Vaziri explained: “A flat tin like a mint tin has to come all the way out of your pocket, and you need two hands to open it.”
The next decision changed its orientation: “We stood it up.”
Vaziri described what the upright shape and flip-top lid were intended to change: “Turning it upright with a flip-top lid means you can reach into your bag or pocket and get a treat out with one hand, without even looking.”
Her example is a walk with several tasks already competing for attention: “If you’ve ever juggled a leash, a coffee, and a poop bag at the same time, you know why that matters.”
Vaziri also described the rattle of treats as a cue she used with her own dog. The lid and sound became parts of the same object: “So it’s a to-go container, a sound cue and the treats, all in one.”
