The invention relates to applicators for applying a solution or other composition (e.g., an antiseptic composition) to skin of a patient. The applicator may include a container body having a proximal end, a distal end, and a frangible member disposed at the distal end of the body. The applicator includes a first position where the container body and frangible member are a unitary piece (e.g., blow molded as a single piece), and a second position when the frangible member is rotated relative to the body to irreversibly break a weak point therebetween, releasing the composition in the hollow body through an opening. A porous applicator head may be positioned adjacent the distal end of the body and frangible member, so that the composition flows out the body, through the opening, and onto the head. The applicator may be formed in a blow-fill-seal process for improved sterility and ease of manufacture.

1. A method of making an aseptic applicator comprising the steps of: (a) extruding a polymeric material;(b) placing said extruded material into a blow mold;(c) molding the extruded material by placing a blow pin into a first end of the extruded material and using pressure to form the material into a
1. A method of making an aseptic applicator comprising the steps of: (a) extruding a polymeric material;(b) placing said extruded material into a blow mold;(c) molding the extruded material by placing a blow pin into a first end of the extruded material and using pressure to form the material into a container body shape comprising a neck portion having a plurality of outwardly extending protrusions at the first end and a substantially hollow handle at a second end;(d) filling said container body at the first end, using said blow pin, with an aseptic composition comprising: (i) an antimicrobial agent and (ii) an alcohol;(e) retracting said blow pin, creating a frangible member at the first end having one or more wings extending toward the second end and adjacent the outwardly extending protrusions of the neck portion of the container body, and sealing the filled container body at the first end, the frangible member and filled container body being a sealed unitary structure of said polymeric material;(f) attaching a porous applicator head to said unitary structure at the first end to form the aseptic applicator; and(g) retaining the porous applicator head with the one or more wings which extend adjacent to the neck portion of the container body. 2. The method of claim 1, wherein said polymeric material is selected from the group consisting of: polyolefins, polypropylene, polyethylene, high density polyethylene, low density polyethylene, ethylene/propylene copolymers, ethylene/butylene copolymers, vinyl, vinyl polymers, acrylic polymers, polyesters, polyethylene terephthalate, polybutylene terephthalate, polyvinyl alcohol, polyamides, polyvinychloride, polyvinylidene chloride, ethylene vinyl alcohol, chlorotrifluoroethylene, polytetrafluoroethylene, chlorotriflouroethylene, polyvinylidene fluoride, copolymers of perfluorinated monomers with partially fluorinated monomers, tetraflouroethylene/hexafluoropropylene/vinylidene, and any mixtures or combinations thereof. 3. The method of claim 2, wherein an inorganic oxide material is incorporated into the polymeric material from which the container body and frangible member are formed. 4. The method of claim 1, wherein said polymeric material is translucent. 5. The method of claim 1, wherein said container body is flexible and deforms under pressure. 6. The method of claim 1, wherein said antimicrobial agent is at least one of chlorhexidine gluconate or povidone iodine. 7. The method of claim 1, wherein said alcohol is selected from the group consisting of: methanol, ethanol, isopropyl alcohol, and butyl alcohol, and any mixtures or combinations thereof. 8. The method of claim 1, further comprising the step of: (h) sterilizing said aseptic applicator using ethylene oxide gas. 9. The method of claim 8, wherein the container body is formed from a single layer of the polymeric material and less than 250 ppm of ethylene oxide penetrates the aseptic applicator into the aseptic composition during sterilization. 10. The method of claim 8, wherein less than 100 ppm of ethylene oxide penetrates the aseptic applicator into the aseptic composition during sterilization. 11. The method of claim 1, wherein vacuum pressure is used to mold the material into the container body shape. 12. The method of claim 1, wherein pressure from compressed gas is used to mold the material into the container body shape. 13. The method of claim 1, further comprising the step of: (h) sterilizing said aseptic applicator using one or more of the following methods: ethylene oxide gas sterilization, dry heat sterilization, UV sterilization, steam sterilization or any combinations thereof. 14. A method of making an aseptic applicator comprising the steps of: (a) extruding a polymeric material;(b) placing said extruded material into a blow mold; and(c) molding the extruded material by placing a blow pin into a first end of the extruded material and using pressure from the blow pin to form the material into an elongate container body shape having an axis extending between the first end and a second end;(d) filling said container body using said blow pin with an aseptic composition comprising: (i) antimicrobial agent, (ii) an alcohol, and (iii) a dye or colorant;(e) retracting said blow pin to form a frangible member at the first end, the step of forming the frangible member sealing the filled container body, the frangible member and filled container body being a unitary structure;(f) attaching a porous applicator head to said unitary structure to form the aseptic applicator;(g) retaining the porous applicator head with one or more wings extending from the frangible member, the wings containing one or more protrusions positioned adjacent to an undercut portion of said container, the undercut aligning with the one or more of the protrusions of the one or more wings to prevent substantial axial movement after the frangible member is broken from the container body; and(h) sterilizing said aseptic applicator using ethylene oxide gas. 15. The method of claim 14, wherein the container body is formed from a single layer of said polymeric material. 16. The method of claim 14, wherein said antimicrobial agent is chlorhexidine gluconate. 17. The method of claim 14, wherein less than 250 ppm of ethylene oxide penetrates the aseptic applicator into the aseptic composition during sterilization. 18. The method of claim 14, wherein vacuum pressure is used to mold the material into the container body shape. 19. The method of claim 14, wherein pressure from compressed gas is used to mold the material into the container body shape. 20. A method of making an aseptic applicator comprising the steps of: (a) extruding a polymeric material;(b) placing said extruded material into a blow mold; and(c) molding the extruded material by placing a blow pin into a first end of the extruded material and using pressure to form the material into a single layer container body shape comprising a neck portion at the first end, the neck having an undercut and a plurality of outwardly extending protrusions, and a substantially hollow handle at the second end;(d) filling said container body using said blow pin with an aseptic composition comprising: (i) antimicrobial agent, (ii) an alcohol, and (iii) a dye or colorant;(e) retracting said blow pin to create a frangible member at the first end and sealing the frangible member to form a frangible member having one or more wings extending toward the second end and adjacent the neck of the container body, the wings of the frangible member each comprising at least one inward protrusion extending between outwardly extending protrusions of the neck portion, the frangible member and filled container body being a unitary structure;(f) attaching a porous applicator head to said unitary structure wherein the one or more wings which extend adjacent to the neck portion of the container body and the outwardly extending protrusions of the neck portion retain the porous applicator head;(g) sterilizing said aseptic applicator using ethylene oxide gas; and(h) packaging said sterilized aseptic applicator into an external packaging comprising at least one flexible portion.
