Abstract
Abstract A device for blurring valuable documents such as banknotes includes means for delivering a blurring or discoloring liquid to deface banknotes contained within an enclosure upon a breach of security afforded by the enclosure. At least one spongy element placed close to the edges of the banknotes which are stacked on edge in the enclosure with which is associated a tank for defacing liquid. Upon the occurrence of a breach the defacing liquid soaks the spongy element which engages the upper cut edges of the banknotes to allow the defacing liquid to migrate on and between the cut edges of these banknotes stored within the enclosure. The device is particularly applicable to cash boxes for automatic bank bills dispensers.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
142 words
In combination, an enclosure, a plurality of documents disposed within the enclosure, and a device associated with said enclosure for defacing said documents when security afforded by said enclosure to said documents is breached; each of said documents being bounded by cut edges, said documents being disposed in generally vertical planes and being arranged face-to-face in a stack having an upper surface; said device including a spongy element disposed above said stack in close proximity to the upper surface thereof, a tank operative associated with said element, and a defacing liquid normally stored in said tank; said liquid being released to soak said element upon breaching of said security whereby said liquid migrates through said element to said upper surface, and contacts those of said cut edges that are disposed at said upper surface and migrates between said documents to deface same.
Claim 2
Dependent Claim
142 words

Claim 3
Dependent Claim
45 words
A combination according to claim 1, wherein the said tank is incorporated into the spongy element and the latter is interposed between the top surface of the stack and a fluid-tight wall of the enclosure and assumes the shape of at least one frangible pocket.
Claim 4
Dependent Claim
29 words
A combination according to claim 2, wherein with said tank is associated with first means that causes perforation of the tank when there is a breach of said security.
