Leakproof mechanism & CapCup
The clear main lid presses into the glass cup. A vent in the small CapCup releases air while closing; cap contraction creates an air-pressure-assisted seal. The soft silicone sip tip completes the drinking closure.
CapCup covers the drinking area between sips to help protect it from everyday dust and splashes. Its appearance design patent application was filed in October 2025 and is pending.

Frequently asked questions
Is it completely leakproof?
Yes under our internal test conditions. Correctly assembled and fully closed cups passed a 24-hour inverted water test and vigorous shaking with no leakage observed.
Can I put it in a bag?
Yes. Confirm the main lid is fully seated, the silicone sip tip and PP straw are correctly installed, and CapCup is fully closed before carrying.
How does the seal work?
The vented CapCup lets air escape during closing; as the cap contracts, the pressure-assisted action tightens the drinking closure.
What does CapCup protect?
When closed, CapCup covers the drinking area to help shield the straw tip from everyday dust and splashes.
Is CapCup patented?
The appearance design patent application was filed in October 2025 and is pending; no granted-patent claim is being made.
Can it hold hot or carbonated drinks?
Hot beverages are supported up to 80 degrees C / 176 degrees F with a burn caution. For carbonation, do not shake and open CapCup slowly away from the face.
Is it dishwasher safe?
Yes. Secure CapCup, the silicone sip tip, PP straw, and other small components in the top rack or a dishwasher basket.

Made for real mornings
