Abstract

The packaging (420) for sponge or porous polymeric devices, e.g., scrubbing brush. The packaging includes a sponge or porous polymeric device (425) therein. A preservative is included in the packaging to prevent bacterial growth on the sponge device.

Claims

1. A storable porous polymeric device comprising:

a porous polymeric member, the member comprising an outer surface and a plurality of impurities distributed through the member, said plurality of impurities including a sodium concentration of less than about 0.2 parts per million;

a preservative applied to said porous polymeric member; and

a containment package enclosing and sealing said preservative and said porous polymeric member within said containment package.

2. The device of claim 1 wherein said preservative capable of repelling charged particles from the porous polymeric member.

3. The device of claim 1 wherein containment package is heat sealed.

4. The device of claim 1 wherein said containment package is provided to enclose and seal said porous polymeric member in a cleanroom to substantially reduce particulate contamination from said porous polymeric member.

5. The device of claim 1 further comprising a package including a preservative therein within said containment package to preserve said porous polymeric member.

6. The device of claim 1 wherein said containment package is a class 10 clear polymer bag.

7. The device of claim 1 wherein said porous polymeric member is selected from a material including polyvinyl acetal porous elastic material.

8. The device of claim 1 wherein said porous polymeric member has a sodium concentration level of less than 0.20 parts per million.

9. The device of claim 1 wherein the porous polymeric member is selected from a brush, a puck, a pad, or a plug.

10. The device of claim 1 wherein said preservative comprises an ammonium bearing compound.

11. The device of claim 1 wherein said preservative comprises an ammonium hydroxide compound to increase a pH factor of said porous polymeric member to reduce a bacterial growth on said porous polymeric member.

12. A packaging apparatus for porous polymeric members, said packaging apparatus comprising:

a porous polymeric member comprising a volume of polyvinyl alcohol material;

a preservative applied homogeneously through said volume of polyvinyl alcohol;

a containment member applied to enclose and seal said porous polymeric member and said preservative within said containment member;

wherein said preservative prevents substantial growth of an organic matter on said porous polymeric member.

13. The apparatus of claim 12 wherein said preservative comprises an ammonium bearing compound to increase a pH factor of said porous polymeric member.

14. The apparatus of claim 12 wherein said containment member is heat sealed to seal and enclose said porous polymeric member and said preservative within said containment member.

15. The apparatus of claim 12 wherein said porous polymeric member is characterized by a shelf live of at least one year from a packaging date for said porous polymeric member.

16. The apparatus of claim 12 further comprises an outer enclosure for enclosing and sealing said containment member.

17. The apparatus of claim 12 wherein said wherein said containment member comprises an inert gas within said containment member.
