“The world’s only coffee cup sleeve that stops leaks at the source.”
THE PROBLEM
"The world's first hot cup sleeve that keeps coffee in your cup, not on your clothes."
WHY LEAKS HURT YOUR BOTTOM LINE
A small design flaw creates three major burdens at scale
Operational Cost
Extra cups and napkins quietly add up to millions in avoidable expense each year
Customer Experience
Spills lead to frustration, complaints and diminished brand trust
Environmental impact
Double-cupping and napkin overuse generate unnecessary waste, undermining sustainability goals
"Stops the leak at the source"

THE SOLUTION
JavaMac® addresses the problem at the source - without redesigning the cup, lid or workflow.
​
HOW IT WORKS
DripSafe ® technology integrates an absorbent liner, wicking away leaking fluid into the sleeve away from your hands, when the sleeve is positioned near the rolled lip of cup.​
​
When fluid escapes at the seam, it is captured and redirected before it can drip onto hands or clothing.
​
No behavior change required.
No new cup design required.
DESIGNED FOR THE REAL WORLD
JavaMac® fits seamlessly into existing operations:
-Compatible with standard paper cups-
-Works with existing lids-
-No changes to exmployee workflow-
THE IMPACT
Small Changes. Massive Scale
Before JavaMac®:
-
Drips force shops to hand out extra napkins and replace spilled drinks.
-
Each replacement costs time, materials, and goodwill.
-
Billions of napkins and cups wasted annually → increased costs and landfill impact.​
After JavaMac®
-
Drips are caught before they spill.
-
Shops save money with fewer wasted napkins and cup replacements.
-
Faster service and cleaner customer experience.
-
Stronger eco-credentials by reducing unnecessary paper waste.
For large coffee chains, these small per-cup savings add up to millions annually — while elevating the customer experience.
Operational Impact
Reduces material waste and lower per-drink costs
Customer Impact
Cleaner hands, fewer complaints, better experiences
Environmental Impact
Less paper waste without asking customers or staff to change behavior

OUR STORY
​​
In 2009, I was walking through downtown Palm Springs with my father-in-law after picking up coffee. As we stepped off the curb to cross the street, I looked down and saw coffee dripping all over my tan slacks and shirt. Confused, I checked the cup — nothing was leaking from the sipper. Looking closer, I realized the coffee was escaping from beneath the lid. At that moment, I knew this was a problem worth solving.
​
After returning home to Sherman Oaks, I began working on early prototypes. Through testing, it became clear that the issue wasn’t the lid at all — it was the paper cup itself. Specifically, the overlap where the paper forms a vertical seam. When the lip is rolled, that seam creates a subtle height difference, allowing liquid to seep between the cup and the lid.
The solution wasn’t to redesign the cup, but to mitigate the failure exactly where it occurs.
​
The name JavaMac™ combines “Java,” a common term for coffee, with “Macintosh” — the British word for a raincoat, named after Charles Macintosh, who patented a rubberized waterproof fabric in 1824.
​
Those early prototypes worked. That work ultimately led to the granting of a U.S. Utility Patent for JavaMac™ with DripSafe™ technology.
