Abstract

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.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 177 words
A disposable antiseptic applicator swab manufactured on a blister forming and sealing machine comprising: a cylindrical crushable glass ampoule having antiseptic liquid therein, a plastic blister package having identical complimentary parts forming a chamber and a flange section, the latter being provided with a channel extending from said chamber to the edge of said flange, said flange having undercut portions at the side edges of said flange adjacent to said channel, the cross section of said blister chamber being slightly larger than the cross section of said ampoule resulting in a relatively tight fit of said ampoule in said blister chamber, and an elongated applicator foam tip folded over said flange at the end thereof having said channel and in communication with the latter so that said antiseptic liquid will penetrate said foam tip when said glass ampoule is crushed, the width of said elongated applicator pad being greater than the width of said flange having the channel therein to prevent contact of the edges of said flange with the channel therein from contact with a patient.
Claim 2
Dependent Claim 177 words
A disposable antiseptic applicator swab manufactured on a blister forming and sealing machine comprising: a cylindrical crushable glass ampoule having antiseptic liquid therein, a plastic blister package having identical complimentary parts forming a chamber and a flange section, the latter being provided with a channel extending from said chamber to the edge of said flange, said flange having undercut portions at the side edges of said flange adjacent to said channel, the cross section of said blister chamber being slightly larger than the cross section of said ampoule resulting in a relatively tight fit of said ampoule in said blister chamber, and an elongated applicator foam tip folded over said flange at the end thereof having said channel and in communication with the latter so that said antiseptic liquid will penetrate said foam tip when said glass ampoule is crushed, the width of said elongated applicator pad being greater than the width of said flange having the channel therein to prevent contact of the edges of said flange with the channel therein from contact with a patient.
