Abstract
An inexpensive disposable antiseptic applicator swab made on a blister forming and sealing machine in which complimentary pockets are made in thermoplastic sheets to form a chamber that receives a crushable glass ampoule containing the antiseptic liquid. The thermoplastic sheets are then heat sealed, leaving an opening into said chamber, said opening being covered by a foam applicator tip through which the antiseptic liquid can penetrate.
