Abstract
An applicator and/or scrub saturated with a desired fluid is packaged in a sealed, liquid-impervious pouch. The liquid-carrying applicator or scrub is made from open-cell, polyurethane foam. A cylinder of the foam is mounted on a stick. The tip end of the foam applicator is fastened to the tip of the stick in a manner that creates a rounded smooth tip. The tip end of the foam applicator may be formed into a smaller brush-like shape.
Claims15
An applicator and cleansing swab comprising:
- a stick handle to be held;
- a first three-dimensional piece of open-cell polyurethane foam mounted on the stick handle at a first end so that said handle pierces the foam material;
- glue on the first tip end of said handle fastening said first foam piece to said stick whereby the end of said foam adjacent to the tip of said handle is attached to said handle by the glue so that the tip of said handle is encased by the foam end;
- a second three-dimensional piece of open-cell, polyurethane foam material of coarser structure than said first piece, mounted on the stick handle at the second end so that said handle pierces the foam material;
- glue on the second tip end of said handle fastening said second foam piece to said stick whereby the end of said foam adjacent to the tip of said handle is attached to said handle by the glue so that the tip of said handle is encased by the foam end;
- and
- a disinfecting fluid contained within said first piece of open-cell foam whereby said second piece of foam at the second end of the said handle may be used to scrape and clean a wound and said first piece of foam at the first end of said handle is used to apply disinfecting fluid to the clean wound.

A fluid dispensing pack containing applicators therein comprising:
- a flexible envelope of liquid-impervious material, said envelope being sealed on all sides;
- a separate chamber in said envelope, containing topical application fluid separated from the envelope by a perforatable seal barrier;
- whereby squeezing said separate chamber will break the seal barrier causing topical application fluid therein to enter the envelope;
- and
- at least one applicator swab located in said envelope, said swab comprising:
- a stick handle to be held;
- a three-dimensional piece of foam mounted on the stick handle so that said handle pierces the foam material;
- and
- adhesion means on the tip of said handle fastening said foam to said stick whereby the end of said foam adjacent to the tip of said handle is attached to said handle by the adhesion means so that the tip of said handle is encased by the foam;
- and
