Abstract
There is described a case for valuable documents, such as notably checks, credit cards, bank notes, etc., comprised of a box with a lid and a closure which may only be opened by inputting a code number, as well as a capsule or phial filled with a pressurized liquid which can destroy or make useless said documents, in which said capsule or phial is made completely or partly from fusible material, and said capsule or phial may be opened or unplugged electrically when electric or electronic means the case is fitted with, are operated due to any break-in attempt.
Claims7
A case for the protection of documents, comprising:
- a closure having box and lid portions which are movable between a closed position and an open position which provides access to the interior of the closure;
- locking means for locking said closure in said closed position, said locking means being unlockable in response to a selected command to allow at least one of said box and said lid portions to be moved to said open position;
- an electrical energy source within said closure;
- capsule means within said closure containing a pressurized liquid material for at least partially destroying the documents when placed in contact therewith, said capsule means having a fusible portion which is openable in response to an electrical opening signal;
- microprocessor means having a plurality of logical OR gates, connected to said electrical energy source, having a plurality of inputs and an output connected to said capsule means for generating said electrical opening signal in response to at least one of said inputs being activated;
- reeiving means for receiving code numbers and having an output connected to said locking means to send said selected command to said locking means in response to a valid code number being received by said receiving means;
- and
- sensing means for sensing various modes of attempted unauthorized entry into said closure connected to electrically activate said microprocessor means inputs, whereby said electrical opening signal is applied to said capsule means to release said liquid material to to said documents upon the sensing of an attempted unauthorized entry into said closure.

- a closure having box and lid portions which are movable between a closed position and an open position which provides access to the interior of the closure;
- locking means for locking said closure in said closed position, said locking means being unlockable in response to a selected command to allow at least one of said box and said lid portions to be moved to said open position;
- an electrical energy source within said closure;
- capsule means within said closure containing a pressurized liquid material for at least partially destroying the documents when placed in contact therewith, said capsule means having a fusible portion which is openable when energized by an electrical energy source;
- means for connecting said electrical energy source to said capsule means so as to energize said fusible portion to release said liquid material onto said documents;
- microprocessor means connected to said electrical energy source, having at least one input and at least one output connected to said locking means for generating said selected command in response to said at least one input being activated;
- electrical keyboard input means for receiving code numbers and having an output electrically connected to said at least one microprocessor input, said electrical keyboard input means and said microprocessor means being connected to send said selected command to said locking means in response to a valid code number being received by said keyboard input means;
- and
- said keyboard input means and said microprocessor means being connected so as to neutralize keyboard entry upon two attempts to enter at least one unvalid code number via said keyboard input means.
