AI Technical Summary

Technical Problem

Existing methods for irreversibly degrading or spoiling banknotes, such as pyrotechnics, ink defacement, and adhesive bonding, face challenges in ensuring quick, unstoppable, and secure degradation, particularly in preventing criminals from removing or reusing partially degraded banknotes.

Method used

A device for mixing and dispensing a multi-component composition, comprising a supply opening, a mixing chamber, and a dispensing opening with a controllable valve, allows for swift and reliable mixing and dispensing of a two-component adhesive. This adhesive is designed to permeate between banknotes, cure quickly, and form a solid block, rendering the banknotes unusable.

Benefits of technology

The device effectively renders banknotes worthless by ensuring rapid and complete adhesion and curing of the adhesive, thereby deterring criminal attempts to steal or reuse the banknotes, while maintaining security features for identification and reimbursement purposes.

Abstract

The invention relates to a device for mixing and dispensing a composition consisting of multiple components. The device comprises a supply opening for a first component, a mixing chamber for mixing the first component with a second component, and a dispensing opening for dispensing the composition comprising a mixture of the first and second components. The device further comprises means for establishing a fluid communication from the supply opening to the dispensing opening, wherein the connecting means comprise a controllable valve. The invention further relates to a device for spoiling securities, like banknotes, stored in a lockable space. The spoiling device comprises a mixing and dispensing device of the type described above and a distribution system connected to the dispensing opening thereof for distributing the composition consisting of multiple components in the lockable space. The invention also relates to a method for spoiling securities, like banknotes, stored in a lockable space, comprising the steps of supplying a first component, supplying a second component, mixing the first and second components into a composition consisting of multiple components, and distributing the composition consisting of multiple components over the securities. And finally, the invention relates to a composition consisting of multiple components, including a first component which comprises a liquid adhesive, and a second component which comprises a powdery activator.
