Container method for product integrity and identification
A container method for product integrity and identification includes a bottle formed from a resin comprising polyethylene terephthalate and a first set of dye stuffs present in the bottle in an amount sufficient to absorb visible and ultraviolet wavelengths which may cause product degradation. A second set of dyestuffs is present in the bottle in an amount sufficient to provide an identifying blue color of the bottle while enabling sufficient transmission of the light for visual inspection of the product contained in the bottle.
1 . A method for storing a pharmaceutical formulation comprising chlorine dioxide, said method comprising:
forming a bottle of a resin comprising polyethylene terephthalate with a first set of dyestuffs present in said bottle in an amount sufficient to absorb visible and ultraviolet wavelengths less than about 420 nm, a second set of dyestuffs present in said bottle in an amount sufficient to absorb visible wavelengths greater than about 500n, the first and second dyestuffs sets allowing transmission of visible blue wavelengths for enabling visual inspection of the product contained in said bottle and providing a product identifying color to said bottle, disposing the pharmaceutical formulation in said bottle; and sealing said bottle.
2 . An ophthalmic product comprising:
a method for storing a pharmaceutical formulation comprising a liquid ophthalmic formulation degrading upon exposure to light of wavelength up to about 420 nm, said formulation comprising chlorine dioxide, said method comprising forming a relatively flat sided dropwise dispensing squeeze bottle for containing the formulation, said bottle being formed from a polyethylene terephalate resin absorbing ultraviolet light at wavelengths below about 312 nm, said bottle having a minimum wall thickness of between about 0.5 mm and about 2 mm and a volume of between about 5 cc and 15 cc first dyestuffs present in said bottle for absorbing visible and ultraviolet light wavelengths between about 312 nm, and about 420 nm, the combination of first dyestuffs and bottle resin reducing degradation of said formulation by light of wavelength up to about 420 nm; and second dyestuffs present in said bottle absorbing most visible wavelengths greater than about 500 nm said first and second dyestuffs being present in amounts providing a product identifying blue color to said bottle while at the same time enabling visual inspection of the formulation through the bottle;
disposing the pharmaceutical formulation in said bottle; and
sealing said bottle.
3 . The method according to claim 2 wherein forming the bottle includes using first dyestuffs comprising yellow and green dyes.
4 . The method according to claim 3 wherein forming the bottle includes using second dyestuffs comprising blue and purple dyes.
