Abstract
Abstract A flexible package of halogen solutions, such as alcohol or water based tinctures of iodine. In certain embodiments, the package is formed of a laminate comprising an inner layer of cast polyvinylchloride, a layer of adhesive, a layer of vinylidene chloride copolymer on the adhesive and an outer layer of polyethylene terephthalate. In other embodiments, a thin aluminum foil coated with paper or cellophane is adhered on to the terephthalate film so as to form the outer layer of such a laminate.

Claim 1
Independent Claim
17 words
A packaging as defined in claim 1 wherein the halogen solution comprises a water-base tincture of iodine.
Claim 2
Dependent Claim
17 words
A packaging as defined in claim 1 wherein the halogen solution comprises an alcohol-base tincture of iodine.
Claim 3
Dependent Claim
24 words
A packaging as defined in claim 1 wherein a layer of a compatible adhesive is provided at least between the second and third lamina.
Claim 4
Dependent Claim
200 words
A packaging consisting essentially of, in combination, a halogen solution and a flexible generally fluid-impervious enclosure for retaining said solution and protecting the same from ambient environment, said enclosure being comprised of a relatively thin flexible and heat-sealable sheet, said sheet comprising a plurality of lamina adhered to each other along configurous surfaces thereof. a first lamina being formed of a relatively thin aluminum foil having a protective coating on one surface thereof to provide vapor-impermeability and printability to said packaging, a second lamina strongly adhered to said first lamina along the exposed aluminum foil surface and bieng formed of polythylene terephthalate resin to provide structural strength to said packaging, a third lamina strong adhered to said second lamina and being formed of a vinylidene chloride copolymer resin to provide vapor-impermeability to said packaging, and a fourth lamina strongly adhered to said third lamina and being formed of a cast polyvinylchloride resin to provide chemical inertness and heat-sealability to said packaging, said enclosure surrounding said solution so that only a face portion of said fourth lamina contacts said solution and so that peripheral edge portions of said fourth lamina are heat-sealed to one another to form a generally fluid-impervious seal.
