Abstract

Abstract A method of sterile packaging which involves the steps of partially filling a container with any of a number of antibacterial agents in liquid or semi-liquid form which contain iodine as the active ingredient, then sealing the container so that the air space is formed above the liquid within the container, and finally heating the container and its contents (which may include a solid object to be sterilized immersed or partially immersed in the liquid) to a temperature substantially below the boiling point of the liquid, and at a pressure of about one atmosphere, until the interior surfaces of the container above and below the liquid level, and the entire contents of such containers, are sterilized.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 99 words
A METHOD OF STERILE PACKAGING COMPRISING THE STEPS OF PARTIALLY FILLING A CONTAINER WITH A SOLUTION OF A STANDARD ANTIBACTERIAL AGENT HAVING AN AVAILABLE IODINE CONCENTRATION WITHIN THE RANGE OF 0.0012 TO 3.0 PERCENT; THEN SEALING SAID CONTAINER TO PROVIDE A GAS SPACE ABOVE SAID SOLUTION WITHIN THE SEALED CONTAINER; AND THEREAFTER HEATING SAID CONTAINER AND ITS CONTENTS TO A TEMPERATURE SUBSTANTIALLY BELOW THE BOILING POINT OF SAID SOLUTION AND AT A PRESSURE OF ABOUT ONE ATMOSPHERE UNTIL THE INTERIOR SURFACES OF SAID CONTAINER ABOVE AND BELOW THE LIQUID LEVEL, AND THE ENTIRE CONTENTS OF SAID CONTAINER, ARE STERILIZED.
Claim 2
Independent Claim 99 words
A METHOD OF STERILE PACKAGING COMPRISING THE STEPS OF PARTIALLY FILLING A CONTAINER WITH A SOLUTION OF A STANDARD ANTIBACTERIAL AGENT HAVING AN AVAILABLE IODINE CONCENTRATION WITHIN THE RANGE OF 0.0012 TO 3.0 PERCENT; THEN SEALING SAID CONTAINER TO PROVIDE A GAS SPACE ABOVE SAID SOLUTION WITHIN THE SEALED CONTAINER; AND THEREAFTER HEATING SAID CONTAINER AND ITS CONTENTS TO A TEMPERATURE SUBSTANTIALLY BELOW THE BOILING POINT OF SAID SOLUTION AND AT A PRESSURE OF ABOUT ONE ATMOSPHERE UNTIL THE INTERIOR SURFACES OF SAID CONTAINER ABOVE AND BELOW THE LIQUID LEVEL, AND THE ENTIRE CONTENTS OF SAID CONTAINER, ARE STERILIZED.
Claim 3
Dependent Claim 26 words
The method of claim 1 in which said container and its contents are heated to a temperature within the range of about 130* to 150* F.
Claim 4
Dependent Claim 12 words
The method of claim 1 in which said gas space contains air.
Claim 5
Dependent Claim 35 words
The method of claim 1 wherein the contents of said container includes a solid object to be sterilized, said method comprising the step of placing said object within said container prior to said sealing step.

The method of claim 4 wherein at least a portion of said object is disposed in said space above the level of said liquid.
Claim 7
Dependent Claim 26 words
The method of claim 5 wherein the portion of said object is disposed above the level of said liquid throughout said filling, sealing, and heating steps.
Claim 8
Dependent Claim 33 words
The method of claim 2 in which said container and its contents are heated to a temperature within the range of 140* to 150* F. for a period in excess of two hours.
