About The Invention
This 32 oz stainless steel cup is a secure and innovative solution for protecting your beverage in shared or high-risk environments. Made from double-wall, vacuum-insulated stainless steel, it keeps drinks hot for up to 12 hours and cold for up to 24. Its durable, matte, powdercoated exterior comes in black, deep green, and charcoal gray—designed to resist scratches and maintain a sleek, tactical appearance.
What sets this cup apart is its dual-locking lid system, which can only be unlocked using a small tubular key. The key disengages two locking mechanisms: one that secures the lid to the body of the cup and another that controls the mouth flap, ensuring your drink remains tamper-proof and spill-resistant. When locked, the cup is completely sealed, making it ideal for travel, military use, or workplaces where security and hygiene are a priority.
The cup measures approximately 10 inches tall with a 3.5-inch base diameter, fitting most cup holders and gear slots. Its high capacity and security features make it perfect for military personnel, first responders, travelers, students, and professionals who need both volume and peace of mind. This cup combines functionality, protection, and durability—making it an essential tool for everyday use in demanding environments.

About the Inventor
About the Developer
Walter came up with the idea of a lockable cup while serving in the military, where shared spaces and constant movement made it easy for drinks to be spilled, lost, or tampered with. He needed a way to keep my beverage secure, clean, and portable during long shifts and field operations. The concept was born from firsthand experience and a desire for practical, everyday protection in demanding environments. (Then he thought this could be for everyone). Walter contacted the Mars Rising Network and had a provisional and design patent application filed and had the invention designed properly so that he may see success with this great idea and turn it into a real product.
He is actively seeking a company that would have an interest in licensing the product for royalty. Working with Mars Rising Network, this essential new design concept was refined and prepared to be presented as a commercial product.
