One  Nurse,  One  Rule,  One  Innovative  Solution:  The  Splitflask  Story
Splitflask founder Cheryl
Splitflask founder Cheryl

The idea for Splitflask came from a simple daily challenge I faced as a NICU nurse: I could only bring one drink container to work. This rule often forced me to choose between my morning coffee and staying hydrated with water throughout my shift. My husband noticed the trail of half-finished Starbucks lattes I’d leave in the car, and he realized the waste wasn’t just about the coffee—it was about having to choose between two essentials because of workplace rules.

Seeing my frustration, he envisioned a solution: a flask that could hold both hot and cold drinks at the same time. With this, I wouldn’t have to sacrifice my coffee for water or the other way around. That’s how Splitflask was born—a simple yet innovative answer to a problem many of us face, designed to make life just a little bit easier.

Frequently asked questions

Can Splitflask really keep drinks both hot and cold at the same time?

Absolutely! Splitflask’s advanced double-walled vacuum insulation technology provides two separate thermal environments within one bottle. This ensures your iced tea stays perfectly chilled while your hot cocoa remains deliciously warm for hours.

Can Splitflask fit in my car cupholder?

Absolutely. Splitflask fits in the majority of car cup holders.

Is Splitflask dishwasher safe?

Yes, Splitflask is dishwasher safe! You can conveniently place it in the dishwasher for easy cleaning without worrying about damaging its durable stainless steel construction or leak-proof seal.
