 Method for sterile packaging and wetting of articles

Details
Inventors: Franchi, Richard M.;
Assignee:
Primary Examiner: Sipos; John
Assistant Examiner:
Attorney, Agent or Firm:

A method of sterile packaging and wetting articles within the package which involves the steps of partially filling a container with any of a number of anti-bacterial agents in liquid or semi-liquid form, then placing articles into the container, then sealing the container so that an air space is formed above the liquid within the container, then heating the container and its contents to a temperature substantially below the boiling point of the liquid, and at a pressure of about one atmosphere, until the surfaces within the container above and below the liquid level, and the entire contents of such container, are sterilized, and finally cooling the container and its contents to a temperature at or below the dew point of the air space until the surfaces within the container and above the liquid level are wetted by the condensed liquid from the air.

DETAILED DESCRIPTION What is claimed is: 1.
A method of sterile packaging and wetting of articles comprising the sequential steps of partially filling a container with a solution of a standard anti-bacterial agent; then placing an article in the container so that the article is partially above the solution; then sealing said container to provide a gas space above the solution within the sealed container; then heating said container and its contents to a temperature substantially below the boiling point of the solution and at a pressure of about one atmosphere until all the surfaces inside the container above and below the solution, and the entire contents of the container, are sterilized; and thereafter cooling the container and its entire contents to a temperature at which condensation occurs on the surfaces inside the container that are above the solution until condensation occurs.
2.
The method of claim 1 in which the anti-bacterial agent is selected from the group consisting of iodophor, sodium ethylmercurithiosalicylate, quartenary ammonium salts, and halogenated bis-phenols.
3.
The method of claim 2 in which the container and its contents are heated to a temperature within the range of 120.
degree.
to 210.
degree.
F.
4.
The method of claim 2 in which the gas space contains air.
5.
The method of claim 2 in which the container and its contents are heated to a temperature within the range of 130.
degree.
to 150.
degree.
F.
for at least 2 hours.
6.
The method of claim 1 in which the solution is standard anti-bacterial agent having an available iodine concentration within the range of 0.
0012 to 3.
0 percent.
7.
The method of claim 6 in which the container and its contents are heated to a temperature within the range of 120.
degree.
to 150.
degree.
F.
8.
The method of claim 1 in which the solution is an aqueous solution of a halogenated 2,2'-bis-phenol having a concentration within the range of 0.
25 to 4.
0 percent.
9.
The method of claim 1 in which the solution is an aqueous solution of a quaternary ammonium salt having a concentration within the range of 0
