## Abstract

The present invention seeks to provide a solution to the problem of personal security by providing a hand-held device that can be legally taken anywhere which will allow a user to effectively deliver a non-pressurized, dry, irritating, non-lethal powder to the eyes of the attacker. Anti-caking material and organic projection material assists with effective delivery. Descriptive labels assure that security officers recognize it as an innocent, food-grade item.

## Claims

### Claim 1

An irritant delivery device consisting of:
a. A hand-held, pocket-sized container;
b. A food-grade, dry irritant material kept inside the container;
