Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
146 words
A personal assault deterrent device comprising: a capsule formed of a single thickness of plastic material, said capsule having a free and uncovered outer surface and an inner surface; a rupturable sealed glass ampoule positioned within said capsule, said ampoule containing therein a volatile composition of a nature adapted to deter and repel a potential assailant, said ampoule having an outer surface in contact with said inner surface of said capsule; said capsule having perforations extending entirely through said single thickness of plastic material, from said free and uncovered outer surface thereof to said inner surface thereof; and said capsule being sufficiently rigid to resist substantial deformation during normal handling, but said capsule being sufficiently deformable such that forceful manual pressure applied to said capsule will cause deformation thereof and will cause said ampoule to rupture, whereby said volatile composition will be dispersed through said perforations.
Claim 2
Dependent Claim
146 words
A personal assault deterrent device comprising: a capsule formed of a single thickness of plastic material, said capsule having a free and uncovered outer surface and an inner surface; a rupturable sealed glass ampoule positioned within said capsule, said ampoule containing therein a volatile composition of a nature adapted to deter and repel a potential assailant, said ampoule having an outer surface in contact with said inner surface of said capsule; said capsule having perforations extending entirely through said single thickness of plastic material, from said free and uncovered outer surface thereof to said inner surface thereof; and said capsule being sufficiently rigid to resist substantial deformation during normal handling, but said capsule being sufficiently deformable such that forceful manual pressure applied to said capsule will cause deformation thereof and will cause said ampoule to rupture, whereby said volatile composition will be dispersed through said perforations.
