Abstract
Abstract A sterilization system preferably utilizing two baths in which articles to be sterilized are immersed into a first bath where the articles are conditioned and then into a second bath containing a sterilizing solution where they are sterilized. The ingredients for the sterilization system are stored in hermetically sealed pouches which are opened just prior to use to release and activate the system. The sterilization system utilizes a chlorine solution which is highly efficacious while being non-corrosive and having a reduced toxicity and prolonged shelf life, and may be utilized by relatively untrained personnel.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
115 words
A package for components for a mixture of the type in which the components are to remain separate until mixed for use, comprising a plurality of layers of superimposed plastic film heat sealed at their edge portion to define a plurality of compartments each sealed from one another, and color indicator means in at least one of said compartments which when mixed with at least one of the components in another compartment effects a color change of at least one of said components to thereby provide visual indication of an internal leak between compartments before the package is opened, thereby providing a visual integrity check at the time the packaging is about to be used.
Claim 2
Dependent Claim
115 words
A package for components for a mixture of the type in which the components are to remain separate until mixed for use, comprising a plurality of layers of superimposed plastic film heat sealed at their edge portion to define a plurality of compartments each sealed from one another, and color indicator means in at least one of said compartments which when mixed with at least one of the components in another compartment effects a color change of at least one of said components to thereby provide visual indication of an internal leak between compartments before the package is opened, thereby providing a visual integrity check at the time the packaging is about to be used.
Claim 3
Dependent Claim
77 words
A package according to claim 1, wherein said plastic film has heat sealed lower edge portions which converge toward one another to form a funnel-like lower end portion on said package such that cutting through said funnel-like lower end through all of said superimposed layers of plastic film simultaneously opens all of said compartments so that the components in each compartment simultaneously flow out from the package and mix with one another to thereby activate said mixture.
Claim 4
Dependent Claim
210 words
A safety and mixing package for components of a sterilizing solution used for sterilizing medical articles and of the type in which the components are to remain separate until mixed and activated for use, comprising a plurality of layers of superimposed plastic film heat sealed at their edge portion to define a plurality of compartments each sealed from one another, said plastic film having heat sealed lower edges with at least portions thereof converging toward one another to form a funnel-like lower end on said package such that cutting of said funnel-like lower end through all of said superimposed layers of plastic film simultaneously opens all of said compartments so that the components in each compartment simultaneously flow out from the package and mix with one another to thereby activate said sterilizing solution, and color indicator means in at least one of said compartments which when mixed with at least one of the components in another compartment effects a color change of at least one of said components to thereby provide visual indication of any internal leak between compartments before the package is opened, thereby providing a safety and visual integrity check at the time the packaging is to be used and precluding inadvertent use of a defective sterilizing solution.
Claim 5
Dependent Claim
210 words
A safety and mixing package for components of a sterilizing solution used for sterilizing medical articles and of the type in which the components are to remain separate until mixed and activated for use, comprising a plurality of layers of superimposed plastic film heat sealed at their edge portion to define a plurality of compartments each sealed from one another, said plastic film having heat sealed lower edges with at least portions thereof converging toward one another to form a funnel-like lower end on said package such that cutting of said funnel-like lower end through all of said superimposed layers of plastic film simultaneously opens all of said compartments so that the components in each compartment simultaneously flow out from the package and mix with one another to thereby activate said sterilizing solution, and color indicator means in at least one of said compartments which when mixed with at least one of the components in another compartment effects a color change of at least one of said components to thereby provide visual indication of any internal leak between compartments before the package is opened, thereby providing a safety and visual integrity check at the time the packaging is to be used and precluding inadvertent use of a defective sterilizing solution.
Claim 6
Dependent Claim
46 words
A safety and mixing package according to claim 3, wherein there is a center compartment and two outer compartments, said color indicator means being disposed in said center compartment such that any leakage between either outer compartment and said center compartment will effect said color change.
Claim 7
Dependent Claim
44 words
A safety and mixing package according to claim 3, wherein one of said compartments contains a chlorine solution, a second contains phosphate, and a third contains a nonionic surfactant, said color indicator means comprises a colorant added to at least one of said components.
Claim 8
Dependent Claim
25 words
A safety and mixing package according to claim 5, wherein said color indicator is selected from the group consisting of chlorophenol red and sodium chromate.
Claim 9
Dependent Claim
141 words
A package for components of a mixture of the type in which the components are to remain separate until mixed for use comprising a plurality of layers of superimposed plastic film heat sealed at their edge portion to define a plurality of compartments each sealed from one another, each of said compartments containing at least one of the components of said mixture, at least two of said compartments being separated by a double wall thickness of plastic film such that the double wall film defines a closed chamber therebetween, and color indicator means in said closed chamber which when mixed with at least one of the components in a juxtaposed compartment effects a color change to thereby provide visual indication that a lead has occurred, thereby providing a visual integrity check at the time the packaging is about to be used.
Claim 10
Dependent Claim
141 words
A package for components of a mixture of the type in which the components are to remain separate until mixed for use comprising a plurality of layers of superimposed plastic film heat sealed at their edge portion to define a plurality of compartments each sealed from one another, each of said compartments containing at least one of the components of said mixture, at least two of said compartments being separated by a double wall thickness of plastic film such that the double wall film defines a closed chamber therebetween, and color indicator means in said closed chamber which when mixed with at least one of the components in a juxtaposed compartment effects a color change to thereby provide visual indication that a lead has occurred, thereby providing a visual integrity check at the time the packaging is about to be used.
Claim 11
Dependent Claim
41 words
A package according to claim 7 further comprising a double wall thickness of plastic film at the external face of an outside compartment of said package to define an external closed chamber, and color indicator means in said external closed chamber.
