Claim 3

The protective cap of claim 1 in which said first chamber has a plurality of inwardly directed ribs which function as energy directors for ultrasonic welding of said absorbant material to said inner chamber.

Claim 4

The protective cap of claim 1 wherein said internal connecting means of said second inner chamber comprise internal threads for threaded cooperation with external threads.

Claim 5

The protective cap of claim 1 further comprising a plurality of gripping fins on an exterior portion of said protective cap.

Claim 6

The protective cap of claim 1 wherein said absorbent material is tube shaped.

Claim 7

The protective cap of claim 1 wherein said skirt of said protective cap is proportioned to securely engage a mating flange of a connector received therein.

Claim 8

A protective cap for an externally threaded, flanged medical connector which securely receives and provides antibacterial effect to the medical connector, said cap comprising: a first, outer chamber having an external opening and having a plurality of inwardly directed ribs, an absorbent material lining said inner chamber, carried on the inner surfaces of said ribs, said absorbent material retaining a liquid antiseptic; a second, inner chamber, smaller than said first chamber and adjacent and open to said first chamber, having internal threads for threaded cooperation with external threads of a connector; and a skirt defined by said external opening to said first inner chamber for sealingly engaging a flange of a connector received in said cap.

Claim 9

A protective cap for an externally threaded, flanged medical connector which securely receives and provides antibacterial effect to the medical connector, said cap comprising: a first, outer chamber having an external opening and having a plurality of inwardly directed ribs, an absorbent material lining said inner chamber, carried on the inner surfaces of said ribs, said absorbent material retaining a liquid antiseptic; a second, inner chamber, smaller than said first chamber and adjacent and open to said first chamber, having internal threads for threaded cooperation with external threads of a connector; and a skirt defined by said external opening to said first inner chamber for sealingly engaging a flange of a connector received in said cap.

Claim 10

The protective cap of claim 7 wherein said absorbent material is made of polyether-based polyurethane and said antiseptic is povidone iodine.

Claim 11

The protective cap of claim 7 wherein a removable water vapor barrier lid completely covers said external opening to said first chamber, and adheres to an outer face of said skirt.

Claim 12

The protective cap of claim 7 wherein said cap wall is made of polyester.

Claim 13

A protective cap for an externally threaded, flanged medical connector which securely receives and provides an antibacterial effect to the medical connector, said cap comprising: a first, outer chamber having an external opening, a tubular thermoplastic, absorbent sponge, said outer chamber having a plurality of inwardly directed ribs serving as energy directors for ultrasonic welding of said tubular absorbent sponge to the inner surfaces of said ribs, said absorbent sponge carrying liquid antiseptic; a second, inner chamber, smaller than said first chamber and adjacent and open to said first chamber, having internal threads for threaded cooperation with external threads of a connector; a skirt defined by said external opening to said first inner chamber for sealingly engaging a flange of a connector received therein; and a removable water vapor barrier lid covering and adhering to an outer face of said skirt.

Claim 14

A protective cap for an externally threaded, flanged medical connector which securely receives and provides an antibacterial effect to the medical connector, said cap comprising: a first, outer chamber having an external opening, a tubular thermoplastic, absorbent sponge, said outer chamber having a plurality of inwardly directed ribs serving as energy directors for ultrasonic welding of said tubular absorbent sponge to the inner surfaces of said ribs, said absorbent sponge carrying liquid antiseptic; a second, inner chamber, smaller than said first chamber and adjacent and open to said first chamber, having internal threads for threaded cooperation with external threads of a connector; a skirt defined by said external opening to said first inner chamber for sealingly engaging a flange of a connector received therein; and a removable water vapor barrier lid covering and adhering to an outer face of said skirt.

Claim 15

The protective cap of claim 11 wherein said skirt of said protective cap defines an annular shoulder which engages an annular flange on said connector to form an annular seal area.

Claim 16

An antibacterial closure system, said system comprising: a protective cap for a connector; said connector comprising a main tubular member having external connecting means; said protective cap comprising: a first, outer chamber having an external opening and fixedly lined with an absorbent material, said absorbent material retaining an antiseptic; and a second, inner chamber having a closed end, smaller than said first chamber and adjacent to said first chamber and communicating therewith for receiving said external connecting means of said connector, the external opening of the first inner chamber being defined by a skirt, said connector defining a flange which is sealingly surrounded by said skirt.

Claim 17

An antibacterial closure system, said system comprising: a protective cap for a connector; said connector comprising a main tubular member having external connecting means; said protective cap comprising: a first, outer chamber having an external opening and fixedly lined with an absorbent material, said absorbent material retaining an antiseptic; and a second, inner chamber having a closed end, smaller than said first chamber and adjacent to said first chamber and communicating therewith for receiving said external connecting means of said connector, the external opening of the first inner chamber being defined by a skirt, said connector defining a flange which is sealingly surrounded by said skirt.

Claim 18

The antibacterical closure system of claim 13 wherein said first chamber has a plurality of inwardly directed ribs serving as energy directors for ultrasonic welding to said absorbent material to said inner chamber.

Claim 19

The antibacterical closure system of claim 13 wherein said external connecting means of said connector comprise external threads, and wherein said internal connecting means of said second inner chamber of said protective cap comprise internal threads for receiving said external threads of said connector.
