Abstract

A glove packaging comprises a container for holding the gloves and a barrier positioned to cover at least a portion of an opening in the container. The barrier protects the gloves from airborne particles and other materials or contaminants that may contaminate the gloves prior to removal from the packaging. The barrier also includes an antimicrobial material for protecting the gloves from microorganisms, pathogens or other materials or contaminants that come in contact with the barrier to further reduce the possibility of contamination.

Claims (28)

1. A packaging for holding and dispensing gloves, the packaging comprising:

a container with a cavity configured to hold the gloves, the container having an opening through which the gloves are removable from the container; and

a barrier attached to the container and covering at least a portion of the opening of the container, the barrier including an antimicrobial material, the antimicrobial material including a combination of zinc-based and silver-based materials which collectively exhibit a minimum 4-log reduction of one or more predetermined pathogens, contaminants, or both,

wherein the antimicrobial material includes approximately 0.075% to 0.1% of total weight of the zinc-based material and approximately 0.1% to 0.5% of total weight of the silver-based material.

2. The packaging of claim 1 , wherein the zinc-based material has a specific gravity of approximately 1.8 and a time-weighted average (TWA) of approximately 0.35 mg/m 3 , and the silver-based material has a specific gravity of approximately 2.7 and a time-weighted average (TWA) of approximately 10 mg/m 3 .

3. The packaging of claim 1 , wherein the antimicrobial material exhibits a minimum 4-log reduction of Staphylococcus aureus ( S. aureus ), methicillin resistant Staphylococcus aureus (MRSA), Klebsiella pneumonia ( K. pneumonia ), Escherichia coli ( E. coli ), Pseudomonas aeruginosa , or Acinetobacter baumannii , or any combinations thereof.

4. The packaging of claim 1 , wherein the antimicrobial material exhibits at least approximately a 4.9 log reduction of S. aureus , at least approximately a 4.9 log reduction of K. pneumonia , at least approximately a 6.0 log reduction of E. coli , and at least approximately a 5.2 log reduction of MRSA.

5. The packaging of claim 1 , wherein the antimicrobial material further exhibits bactericide, fungicide, or algaecide characteristics, or any combinations thereof.

6. The packaging of claim 1 , wherein at least a portion of the barrier is corona treated to thereby increase the surface tension of the barrier.

7. The packaging of claim 1 , wherein at least a portion of the barrier is treated to thereby increase the surface tension of the barrier to at least approximately 42 dynes.

8. The packaging of claim 1 , wherein the barrier exhibits a minimum peel-force strength of at least approximately 166 N/m.

9. The packaging of claim 1 , wherein the barrier exhibits an average maximum pull-off force of at least approximately 184 N/m.

10. The packaging of claim 1 , wherein the barrier comprises a polymeric film.

11. The packaging of claim 10 , wherein the antimicrobial material is added to the barrier by mixing the antimicrobial material with the barrier before extrusion thereof.

12. The packaging of claim 1 , wherein the barrier has a thickness of from about 1 mil to about 6 mils.

13. A packaging for holding and dispensing gloves, the packaging comprising:

a container with a cavity configured to hold the gloves, the container having an opening through which the gloves are removable from the container; and

a barrier attached to the container and covering at least a portion of the opening of the container, the barrier including an antimicrobial material, the antimicrobial material including a combination of zinc-based and silver-based materials which collectively exhibit a minimum 4-log reduction of one or more predetermined pathogens, contaminants, or both,

wherein the silver-based material comprises glass, oxide, and silver phosphate, and wherein the zinc-based material comprises Bis(1-hydroxy-2(1H)-pyridinethionato-O,S)-(T-4) zinc and 2-Pyridinol-1-oxide.

14. The packaging of claim 13 , wherein the antimicrobial material includes approximately 0.075% to 0.1% of total weight of the zinc-based material and approximately 0.1% to 0.5% of total weight of the silver-based material.

15. The packaging of claim 13 , wherein the zinc-based material has a specific gravity of approximately 1.8 and a time-weighted average (TWA) of approximately 0.35 mg/m 3 , and the silver-based material has a specific gravity of approximately 2.7 and a time-weighted average (TWA) of approximately 10 mg/m 3 .

16. The packaging of claim 13 , wherein the antimicrobial material exhibits at least approximately a 4.9 log reduction of S. aureus , at least approximately a 4.9 log reduction of K. pneumonia , at least approximately a 6.0 log reduction of E. coli , and at least approximately a 5.2 log reduction of MRSA.

17. The packaging of claim 13 , wherein at least a portion of the barrier is corona treated to thereby increase the surface tension of the barrier.

18. The packaging of claim 13 , wherein the barrier exhibits a minimum peel-force strength of at least approximately 166 N/m.

19. The packaging of claim 13 , wherein the barrier exhibits an average maximum pull-off force of at least approximately 184 N/m.

20. A glove container for holding and dispensing a plurality of gloves, the container comprising:

a polyhedral paper-based body portion configured to enclose therein the plurality of gloves, the body portion defining an opening through which one or more of the gloves is removable by a user; and

a polymeric film adhered to an underside surface of a top wall of the body portion, the polymeric film covering the opening and including a slit through which one or more of the gloves is removable by the user, the polymeric film including an antimicrobial material, the antimicrobial material including approximately 0.075% to 0.1% of total weight of a zinc-based material and approximately 0.1% to 0.5% of total weight of a silver-based material.
