Abstract
Abstract The invention relates to an intraoral dispensing apparatus for rendering the breath of a person aromatically pleasant. A vesicle is disposed about and in contact with the gingiva or dental gums and contains a supply of breath deodorizing or sweetening solution, which may include medications. A valve is provided for selectively dispensing solution as desired by the user, and is activated by finger pressure on the outside of the cheek. The dispensing valve operates only selectively to release solution to avoid flavor contamination of food when eating. Filling means are provided to recharge the vesicle. An alternative model is adaptable for use with dentures and can comprise a vesicle formed from a single layer of material attached about its periphery on the gingival surface of the denture. Other alternatives include combination of the foregoing with a bite opener, temporo-mandibular joint syndrome corrector, herbst appliance, etc.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
123 words
A gingival breath deodorizer comprising: a body molded for attachment and close fitting relationship to dental gingiva; a vesicle disposed within the body, said vesicle being suitable for retention of fluid; a selectively operable filling aperture in fluid communication with the vesicle; said vesicle being defined by a premanufactured, substantially cylindrical, flexibly sided bladder attached to a buccal portion of the body and having at least one selectively operable orifice in fluid communication with the vesicle to serve as filling and dispensing means; and a first orifice at a first end of the bladder service as the filling means and a second orifice at a second end of the bladder serving as the dispensing means, each orifice also acting as a check valve.
Claim 2
Dependent Claim
123 words
A gingival breath deodorizer comprising: a body molded for attachment and close fitting relationship to dental gingiva; a vesicle disposed within the body, said vesicle being suitable for retention of fluid; a selectively operable filling aperture in fluid communication with the vesicle; said vesicle being defined by a premanufactured, substantially cylindrical, flexibly sided bladder attached to a buccal portion of the body and having at least one selectively operable orifice in fluid communication with the vesicle to serve as filling and dispensing means; and a first orifice at a first end of the bladder service as the filling means and a second orifice at a second end of the bladder serving as the dispensing means, each orifice also acting as a check valve.
Claim 3
Dependent Claim
15 words
The deodorizer of claim 1 in which at least one orifice is a duckbill valve.
Claim 4
Dependent Claim
167 words
A gingival breath deodorizer comprising: a body molded for attachment and close fitting relationship to dental gingiva; a vesicle disposed within the body, said vesicle being suitable for retention of fluid; and a selectively operable dispensing valve in fluid communication with the vesicle, said dispensing valve being comprised of: a base fabricated of a resiliently compressible material; upper tapered surfaces having a minimum diameter exteriorly; a tapered diameter opening penetrating the body for fluid communication with the vesicle, walls of said opening being tapered with a minimum diameter exteriorly and said walls being shaped to mate with the upper tapered surfaces of the valve to effect sealing therebetween; and an umbrella portion projecting about the opening and attached to the upper tapered surfaces, such that when pressure is manually applied to the umbrella portion, said pressure results in temporary compression at the base and temporary separation of the upper tapered surfaces from mating walls of the opening thereby allowing fluid retained in the vesicle to selectively escape.
Claim 5
Dependent Claim
167 words
A gingival breath deodorizer comprising: a body molded for attachment and close fitting relationship to dental gingiva; a vesicle disposed within the body, said vesicle being suitable for retention of fluid; and a selectively operable dispensing valve in fluid communication with the vesicle, said dispensing valve being comprised of: a base fabricated of a resiliently compressible material; upper tapered surfaces having a minimum diameter exteriorly; a tapered diameter opening penetrating the body for fluid communication with the vesicle, walls of said opening being tapered with a minimum diameter exteriorly and said walls being shaped to mate with the upper tapered surfaces of the valve to effect sealing therebetween; and an umbrella portion projecting about the opening and attached to the upper tapered surfaces, such that when pressure is manually applied to the umbrella portion, said pressure results in temporary compression at the base and temporary separation of the upper tapered surfaces from mating walls of the opening thereby allowing fluid retained in the vesicle to selectively escape.
