Abstract
Abstract The present invention is a spray container for use in applying a cyanoacrylate ester composition which is a liquid and which is disposed in the spray container. The spray container includes a container which is constructed from an air-impermeable material and which has a valve with a nozzle. The spray container also includes a spraying mechanism which has a spray head with one or more apertures or orifices and a cylinder with a piston. The movement of the piston in the cylinder draws the liquid into the spray head in order to atomize and spray the liquid through the apertures upon forward movement of the piston. The spray container discharges the fine mist of atomized particles of the cyanoacrylate ester composition onto two opposing surfaces which are to be adhesively joined together or fumes an object suspected of containing latent fingerprints.

A spray container for use in a self-contained fingerprinting kit or for use in applying adhesive material which comprises: a. a container associated with a valve with a nozzle; b. a cyanoacrylate ester which is a liquid disposed in said container; and c. discharging means for discharging a fine mist of atomized particles of said cyanoacrylate ester through said nozzle for fuming an object suspected of containing latent fingerprints or for discharging onto at least one of two opposing surfaces which are to be joined.
Claim 2
Dependent Claim
85 words
A spray container for use in a self-contained fingerprinting kit or for use in applying adhesive material which comprises: a. a container associated with a valve with a nozzle; b. a cyanoacrylate ester which is a liquid disposed in said container; and c. discharging means for discharging a fine mist of atomized particles of said cyanoacrylate ester through said nozzle for fuming an object suspected of containing latent fingerprints or for discharging onto at least one of two opposing surfaces which are to be joined.
Claim 3
Dependent Claim
30 words
The spray container of claim 1 wherein said cyanoacrylate ester is dispersed in a chlorinated organic solvent to produce a mixture of said chlorinated organic solvent and said cyanoacrylate ester.
Claim 4
Dependent Claim
51 words
The spray container of claim 2 wherein a fluorescent dye is added to said mixture of said chlorinated organic solvent and said cyanoacrylate ester in order to generate fluorescent vapor fumes whereby said latent fingerprints become exposed when an ultraviolet light source is shined on said object containing said latent fingerprints.
Claim 5
Dependent Claim
32 words
The spray container of claim 1 wherein said discharging means is a spring actuated pump device which includes a discharge valve for effecting spraying of a desired quantity of said cyanoacrylate ester.
Claim 6
Dependent Claim
14 words
The spray container of claim 1 wherein said discharging means is a hand-held apparatus.
Claim 7
Dependent Claim
68 words
The spray container of claim I wherein said discharging means is a spraying mechanism which includes a spray head with one or more apertures or orifices and a cylinder with a piston wherein the movement of said piston in said cylinder draws the liquid cyanoacrylate ester into said spray head in order to atomize and spray said liquid through said apertures upon oppositely disposed movement of said piston.
Claim 8
Dependent Claim
112 words
7 . An aerosol spray container for use in a self-contained fingerprinting kit, said aerosol spray container comprising: a. a container associated with a valve with a nozzle; b. a hydrocarbon propellant which is disposed in said container; c. a mixture of a chlorinated organic solvent and a cyanoacrylate ester which is disposed in said container and which is discharged along with said hydrocarbon propellant through said nozzle of said valve of said container whereby said aerosol spray container discharges a fine mist of atomized particles of said mixture of said chlorinated organic solvent and said cyanoacrylate ester along with said hydrocarbon propellant for fuming an object suspected of containing latent fingerprints.
Claim 9
Dependent Claim
112 words
7 . An aerosol spray container for use in a self-contained fingerprinting kit, said aerosol spray container comprising: a. a container associated with a valve with a nozzle; b. a hydrocarbon propellant which is disposed in said container; c. a mixture of a chlorinated organic solvent and a cyanoacrylate ester which is disposed in said container and which is discharged along with said hydrocarbon propellant through said nozzle of said valve of said container whereby said aerosol spray container discharges a fine mist of atomized particles of said mixture of said chlorinated organic solvent and said cyanoacrylate ester along with said hydrocarbon propellant for fuming an object suspected of containing latent fingerprints.
Claim 10
Dependent Claim
52 words
The aerosol spray container of claim 7 wherein a fluorescent dye is added to said mixture of said chlorinated organic solvent and said cyanoacrylate ester in order to generate fluorescent vapor fumes whereby said latent fingerprints become exposed when an ultraviolet light source is shined on said object containing said latent fingerprints.
Claim 11
Dependent Claim
