Abstract

A package for holding and dispensing surgical masks, respirators, face shields and other articles having eye shields made from a substantially transparent, flexible material susceptible to abrasion or scratching. The surgical masks are stacked within the container one upon another and a fanning force is applied to each eye shield such that the eye shields become semi-rigid and fan apart, one from the next in the stack. In such condition scratching caused by the eye shields rubbing against each other is virtually eliminated, and the surgical masks are dispensed in a convenient scratch-free manner.

Claims

1. A method of packaging and dispensing a plurality of face shields each comprising a flexible, substantially transparent, abrasion sensitive eye shield portions, the method comprising the steps of:

providing a container having a bottom comprising a raised central portion with an apex along a line parallel to a minor axis of the container;

stacking the face shields within the container such that the eye shield portions are in a bent configuration over the raised central portion of the container; and

applying a fanning force to the plurality of face shields such that the eye shield portions are held in a semi-rigid, separated condition so that abrasion of the eye shield portions is minimized.

2. The method of claim 1 wherein the raised central portion comprises an inverted V.

3. The method of claim 1 wherein the face shield comprises a surgical face mask material attached to the eye shield portion.

4. The method of claim 3 wherein the face shield further comprises attachment means attached thereto adapted to position the face shield around the head of a wearer, and further wherein the raised central portion comprises a cut-out adapted to position the attachment means below the raised central portion.

5. The method of claim 4 wherein the attachment means are selected from a group comprising tie strings, elastic bands or ear loops.

6. A method of packaging and dispensing a plurality of face shields each comprising a flexible, substantially transparent, abrasion-sensitive eye shield portions, the method comprising the steps of:

providing a container having a major and a minor axis and a bottom comprising a raised central portion with an apex along a line parallel to a minor axis of the container; and

stacking the face shields within the container so that the eye shield portions are in a bent configuration over the raised central portion of the container such that the eye shield portions are held in a semi-rigid, separated condition so that abrasion of the eye shield portions is minimized.

7. The method of claim 6 wherein side walls of the container apply a compressive force to maintain the eye shield portions in the bent configuration.

8. The method of claim 6 wherein the raised central portion comprises an inverted V.

9. The method of claim 6 wherein the face shield comprises a surgical face mask material attached to the eye shield portion.

10. The method of claim 9 wherein the face shield further comprises attachment means attached thereto adapted to position the face shield around the head of a wearer, and further wherein the raised central portion comprises a cut-out adapted to position the attachment means below the raised central portion.

11. The method of claim 10 wherein the attachment means are selected from a group comprising tie strings, elastic bands or ear loops.

12. A package for retaining and dispensing a plurality of face shields each comprising a flexible, substantially transparent, abrasion-sensitive eye shield portions, the package comprising:

a container having a bottom comprising a raised central portion with an apex along a line parallel to a minor axis of the container;

a stack of face shields within the container such that the eye shield portions are in a bent configuration over the raised central portion of the container; and

means for applying a fanning force to the plurality of face shields such that the eye shield portions are held in a semi-rigid, separated condition so that abrasion of the eye shield portions is minimized.

13. The package of claim 12 wherein the raised central portion comprises an inverted V.

14. The package of claim 12 wherein the face shield comprises a surgical face mask material attached to the eye shield portion.

15. The package of claim 14 wherein the face shield further comprises attachment means attached thereto adapted to position the face shield around the head of a wearer, and further wherein the raised central portion comprises a cut-out adapted to position the attachment means below the raised central portion.

16. The package of claim 15 wherein the attachment means are selected from a group comprising tie strings, elastic bands or ear loops.

17. A package for retaining and dispensing a plurality of face shields each comprising a flexible, substantially transparent, abrasion-sensitive eye shield portions, the package comprising:

a container having a major and a minor axis and a bottom comprising a raised central portion with an apex along a line parallel to a minor axis of the container; and

a plurality of face shields stacked within the container so that the eye shield portions are in a bent configuration over the raised central portion of the container, each eye shield portion being held in a semi-rigid, separated condition so that abrasion of the eye shield portions is minimized.

18. The package of claim 17 wherein the container comprises side walls for apply a compressive force to maintain the eye shield portions in the bent configuration.

19. The package of claim 17 wherein the raised central portion comprises an inverted V.

20. The package of claim 17 wherein the face shield comprises a surgical face mask material attached to the eye shield portion.

21. The package of claim 20 wherein the face shield further comprises attachment means attached thereto adapted to position the face shield around the head of a wearer, and further wherein the raised central portion comprises a cut-out adapted to position the attachment means below the raised central portion.

22. The package of claim 21 wherein the attachment means are selected from a group comprising tie strings, elastic bands or ear loops.
