Sterilization wrap with additional strength sheet
View Patent ↗A sterilization wrap is provided. The sterilization wrap includes a first sheet that is configured for providing a barrier to prevent at least some bacteria from passing therethrough while allowing sterilization gas to pass therethrough. A second sheet is attached to the first sheet. The second sheet is located on the first sheet so that a perimeter of the second sheet is contained entirely within a perimeter of the first sheet.
1. A sterilization wrap, comprising:
a first outer sheet adapted for use in a sterilization environment, said first sheet providing bacterial filtration to prevent at least some bacteria from passing therethrough, said first sheet configured to allow sterilization gas to pass therethrough for sterilizing objects, said first sheet having a perimeter and having an upper surface with a surface area, said first sheet includes a laminate that has a spunbonded layer, a meltblown layer, and a spunbonded layer, wherein the laminate has a basis weight of from 16.96 gsm to 118.69 gsm; and
a second inner sheet attached to said upper surface of said first sheet, said second sheet having a perimeter and said second sheet located on said first sheet so that said perimeter of said second sheet is contained entirely within said perimeter of said first sheet, said second sheet having an upper surface with a surface area, said second sheet containing an absorbent material and being configured to allow sterilization gas to pass therethrough, wherein said second sheet has a basis weight higher that the first sheet and greater than 118.69 gsm;
wherein said surface area of said second sheet is less than half of said surface area of said first sheet, and wherein said first and second sheets are releasably attached to one another through an attachment selected from the group consisting of hook and loop fasteners and tape.
2. The sterilization wrap as set forth in claim 1 , wherein said second sheet is configured for providing a barrier so as to prevent at least some bacteria from passing therethrough.
3. The sterilization wrap as set forth in claim 1 , wherein said second sheet has a higher porosity than said first sheet.
4. The sterilization wrap as set forth in claim 1 , wherein both said first and second sheets have a rectangular shaped upper surface, and wherein said second sheet is oriented on said upper surface of said first sheet such that the sides of said second sheet are oriented at 45° angles to the sides of said first sheet.
5. The sterilization wrap as set forth in claim 1 , wherein the surface area of said second sheet is from 18% to 44% of the surface area of said first sheet.
6. The sterilization wrap as set forth in claim 1 , wherein said second sheet is attached over the entire area of the bottom surface of said second sheet to said first sheet.
7. The sterilization wrap as set forth in claim 1 , wherein said second sheet is attached over less than the entire area of the bottom surface of said second sheet to said first sheet.
8. The sterilization wrap as set forth in claim 1 , wherein the perimeter of said second sheet is attached to said first sheet.
9. The sterilization wrap as set forth in claim 8 , wherein the perimeter of said second sheet is attached intermediately to said first sheet.
10. The sterilization wrap as set forth in claim 1 , wherein said first sheet includes an additional laminate that has a spunbonded layer, a meltblown layer, and a spunbonded layer, and wherein said pair of laminates are joined by a plurality of spaced apart and separate bond points.
11. The sterilization wrap as set forth in claim 1 , wherein said second sheet is oriented from 20° to 70° in relation to the sides of the first sheet.
12. The sterilization wrap as set forth in claim 1 , wherein the second sheet includes a high loft material.
13. The sterilization wrap as set forth in claim 1 , wherein the first sheet is made from a pair of laminates.
14. The sterilization wrap as set forth in claim 13 , wherein the pair of laminates are joined by a plurality of spaced apart and separate bond points.
