Abstract

A method and apparatus for packaging sterile surgical masks so that individual masks can be dispensed one at a time without disturbing the masks remaining in the dispenser. The method employs stacking surgical masks one upon another and aligning the tie strings so that they have essentially the same direction. The stack of sterile surgical masks with tie strings thus aligned is then inserted into a bag and the bag is tied at one end so as to enclose the masks therein. The bag and its contents are then sterilized and placed in a container. Both the bag and the container are long enough to permit the tie strings to trail loosely behind the stack of masks, and the bag and container are wide enough to permit the tie strings at the sides of the stack of masks to lie loosely and in a generally horizontally aligned fashion, thus permitting the masks to be serially removed without tangling the tie strings.

Claims

1. A method of packaging surgical masks such that said masks can be dispensed one at a time without entangling the tie strings of the masks, the method comprising the steps of:

stacking said surgical masks one upon the other;

gathering said tie strings into columns at each corner of the stack of said masks;

providing a container having a length that is long enough to permit the tie strings at one end of said stack of masks to be extended toward one end of said container, and a width that is wide enough to permit the tie strings at the other end of said stack to be extended along the sides of said stack toward said end of the container; and

inserting said surgical masks into said container such that said tie strings will trail loosely behind and at the sides of said stack of masks so as to permit each mask to be freely withdrawn from said container without entangling other masks.

2. A method as defined in claim 1 wherein said step of inserting said stack of surgical masks comprises placing the narrower edge of said masks adjacent to the access opening of said container.

3. A method as defined in claim 1 wherein said step of inserting said stack of surgical masks comprises placing the wider edge of said masks adjacent to the access opening of said container.

4. A method as defined in claim 1 wherein said inserting step comprises the steps of:

enclosing said stack of surgical masks in a gas permeable bag that generally corresponds in length and width to the length and width of said container;

enclosing said stack of masks within said bag;

placing said bag within said container; and

enclosing said container.

5. A method as defined in claim 4 further comprising the step of perforating said bag so as to provide a tear out section in said bag for later removal of said surgical masks from said bag.

6. A method as defined in claim 1 further comprising the step of sterilizing said container and its contents.

7. A method of packaging surgical masks such that said masks can be dispensed one at a time without entangling the tie strings of the masks, the method comprising the steps of:

stacking said surgical masks one upon the other;

gathering said tie strings into columns at each corner of the stack of said surgical masks;

providing a container having a length that is long enough to permit the tie strings at one end of said stack of masks to be extended toward one end of said container, and a width that is wide enough to permit the tie strings at the other end of said stack to be extended along the sides of said stack toward said end of the container;

inserting said stack of surgical masks into a gas permeable bag that generally corresponds in length and width to the length and width of said container, thereby permitting said tie strings to trail loosely behind and at the sides of said stack of masks;

closing said bag so as to enclose said stack of masks therewithin;

sterilizing said bag and its contents by gas treatment;

placing said bag in said container; and

enclosing said container.

8. A stack of sterile surgical masks in a package, said masks further including tie strings at each ends, the package comprising a container having a length being long enough such that the tie strings at one end of said stack of masks extend free from entanglement toward one end of said container, said container further having a width being wide enough such that the tie strings at the other end of said stack extend free from entanglement along the sides of said stack toward said end of the container, said container further having opening means for acessing said stack of surgical masks to be dispensed one at a time without entangling the tie strings of the masks.

9. A package as defined in claim 8 further comprising a bag to be placed in said container and which encloses therein said stack of masks, said bag having a length that is long enough to permit the tie strings at one end of said stack of masks to be extended toward one end of said container, said bag further having a width that is wide enough to permit the tie strings at the other end of said stack to be extended along the sides of said stack toward said end of the container, and said bag further having first opening means which are recloseable for placing said stack of surgical masks into said bag and second opening means adjacent to said surgical masks for accessing said stack of surgical masks.

10. A package as defined in claim 9 wherein said second opening means comprise a perforated portion of said bag that may be removed to expose said masks to finger access.

11. A package as defined in claim 8 wherein the opening means of said container comprises a lid having means for relocking said lid to close said container, and means for removing said lid from said container when desired.
