Abstract
Abstract A safe, effective self-defense device including a container having a non-toxic deterrent fluid mixture therein is disclosed. The container is provided as a thin-walled, manually-collapsible, squeeze bottle having a nozzle, a nozzle closure cap and a sealing substance positioned in the nozzle, which cap can be removed and the sealing substance ejected from the nozzle by a single hand of the user. The deterrent mixture includes a surfactant lachyrmal agent, a food-grade dye and an odor or oleofactory agent.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
254 words
A safe, effective self-defense device including container means, and a deterrent fluid including at least one of a lachrymal agent, a dye and an olefactory agent disposed in said container means, said container means being formed of a flexible material having sufficiently thin walls to enable collapsing at said walls by one hand of a user to enable selective discharge of said deterrent fluid by said user for self-defense, wherein the improvement in said self-defense device comprises: said container means being provided with nozzle means having an inlet portion, an outlet portion and a throat portion of reduced diameter disposed therebetween, said nozzle means being formed to produce a coherent stream of said fluid upon manual collapsing of the walls of said container means; and nozzle sealing and closure means mounted to said nozzle means and including cap means mounted to said nozzle means and a sealing substance positioned in said throat portion downstream of said inlet portion of said nozzle means, said nozzle sealing and closure means being formed to prevent accidental discharge of said deterrent fluid from said container means, and said cap means further being formed for rapid removal from said nozzle means with the hand of the user used to collapse said walls and said sealing substance being selected for rapid ejection from said throat portion and said nozzle means upon collapsing of said container for discharge of said deterrent fluid through said nozzle means after ejection of said sealing substance upon continued collapsing of said container by the user.
Claim 2
Dependent Claim
254 words
A safe, effective self-defense device including container means, and a deterrent fluid including at least one of a lachrymal agent, a dye and an olefactory agent disposed in said container means, said container means being formed of a flexible material having sufficiently thin walls to enable collapsing at said walls by one hand of a user to enable selective discharge of said deterrent fluid by said user for self-defense, wherein the improvement in said self-defense device comprises: said container means being provided with nozzle means having an inlet portion, an outlet portion and a throat portion of reduced diameter disposed therebetween, said nozzle means being formed to produce a coherent stream of said fluid upon manual collapsing of the walls of said container means; and nozzle sealing and closure means mounted to said nozzle means and including cap means mounted to said nozzle means and a sealing substance positioned in said throat portion downstream of said inlet portion of said nozzle means, said nozzle sealing and closure means being formed to prevent accidental discharge of said deterrent fluid from said container means, and said cap means further being formed for rapid removal from said nozzle means with the hand of the user used to collapse said walls and said sealing substance being selected for rapid ejection from said throat portion and said nozzle means upon collapsing of said container for discharge of said deterrent fluid through said nozzle means after ejection of said sealing substance upon continued collapsing of said container by the user.
Claim 3
Dependent Claim
39 words
The self-defense device as defined in claim 1 wherein, said deterrent fluid includes a dye which is a mixture of Red Dye No. 3 and Red Dye. No. 40 in about equal proportions to produce a blood red color.
Claim 4
Dependent Claim
197 words
In a self-defense device including container means; and a deterrent fluid including at least one of a lachrymal agent, a dye and an olefactory agent disposed in said container means; said container means being formed of a flexible material having sufficiently thin walls to enable collapsing of said walls by one hand of a user to enable selective discharge of said deterrent fluid by said user for self-defense, said container means further having nozzle means formed to produce a coherent stream of said deterrent fluid upon manual collapsing or said walls, and said container means having removable cap means mounted to said nozzle means to prevent accidental discharge of said deterrent fluid from said container means; the improvement comprising: said nozzle means include a nozzle shoulder formed in an exterior surface thereof, said cap means is formed as a resiliently displaceable cap having a cap shoulder formed for mating interengagement with and snap-acting release from said nozzle shoulder, and said cap includes securement means coupled to said cap and formed for securement to one of said user and the clothing of said user for removal of said cap by pulling said device away from said securement means.
Claim 5
Dependent Claim
197 words
In a self-defense device including container means; and a deterrent fluid including at least one of a lachrymal agent, a dye and an olefactory agent disposed in said container means; said container means being formed of a flexible material having sufficiently thin walls to enable collapsing of said walls by one hand of a user to enable selective discharge of said deterrent fluid by said user for self-defense, said container means further having nozzle means formed to produce a coherent stream of said deterrent fluid upon manual collapsing or said walls, and said container means having removable cap means mounted to said nozzle means to prevent accidental discharge of said deterrent fluid from said container means; the improvement comprising: said nozzle means include a nozzle shoulder formed in an exterior surface thereof, said cap means is formed as a resiliently displaceable cap having a cap shoulder formed for mating interengagement with and snap-acting release from said nozzle shoulder, and said cap includes securement means coupled to said cap and formed for securement to one of said user and the clothing of said user for removal of said cap by pulling said device away from said securement means.
