Abstract
Abstract A system for impregnating and dispensing a swab. An outer bag is provided having at least one swab and a burst pouch located therein. The burst pouch is opened within the bag while the bag is sealed, impregnating the swab before its removal. The bag is then opened, and the impregnated swab is removed through an access opening in the bag. The access opening is located so that the bag may be lain horizontally without liquid in the bag spilling from the bag. The pouch is oriented in the bag to be in proximity to the absorbent head of the swab.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
132 words
A system for impregnating and dispensing a swab, comprising a. an outer, sealed bag having at least one swab located therein, said bag comprising opposite, generally flat, flexible sides sealed along side edges and end edges thereof, b. a frangible pouch disposed within said sealed bag, said pouch containing a liquid and including means for opening said pouch while sealed within said bag for releasing said liquid within said sealed bag to impregnate said swab so that said swab becomes an impregnated swab, and c. access means on one side of said bag extending laterally across a portion of said one side and being spaced from the side edges and end edges of said bag for allowing removal of an impregnated swab from said bag while excess liquid remains within said bag.
Claim 2
Independent Claim
132 words
A system for impregnating and dispensing a swab, comprising a. an outer, sealed bag having at least one swab located therein, said bag comprising opposite, generally flat, flexible sides sealed along side edges and end edges thereof, b. a frangible pouch disposed within said sealed bag, said pouch containing a liquid and including means for opening said pouch while sealed within said bag for releasing said liquid within said sealed bag to impregnate said swab so that said swab becomes an impregnated swab, and c. access means on one side of said bag extending laterally across a portion of said one side and being spaced from the side edges and end edges of said bag for allowing removal of an impregnated swab from said bag while excess liquid remains within said bag.
Claim 3
Dependent Claim
20 words
A system according to claim 1 in which said means for opening comprises an area of weakening in said pouch.
Claim 4
Dependent Claim
40 words
A system according to claim 1 in which said means for opening comprises an excess quantity of entrapped air within said pouch such that compression of said pouch causes the entrapped air to fracture said pouch to release said liquid.
Claim 5
Dependent Claim
26 words
A system according to claim 1 in which said access means comprises a line of weakening in one wall of said bag on said one side.
Claim 6
Dependent Claim
14 words
A system according to claim 4 in which said line of weakening is perforated.
Claim 7
Dependent Claim
31 words
A system according to claim 1 in which said access means comprises a slit in one wall of said bag on said one side, and including release means sealing said slit.
Claim 8
Dependent Claim
16 words
A system according to claim 6 in which said release means comprises a peel away tab.
Claim 9
Dependent Claim
23 words
A system according to claim 1 in which said means for opening comprises means to pierce said pouch while seated within said bag.
Claim 10
Dependent Claim
23 words
A system according to claim 8 in which said means to pierce comprises a clip engaging said pouch and having a puncturing tip.
Claim 11
Dependent Claim
14 words
A system according to claim 1 including means for metering liquid impregnating said swab.
Claim 12
Dependent Claim
53 words
A system according to claim 10 in which said access means comprises a slit and said swab includes an absorbent head, and said metering means comprises sizing of said slit relative to said absorbent head such that said slit squeezes excess liquid from said head as said swab is removed through said slit.
Claim 13
Dependent Claim
15 words
A system according to claim 11 including a peel away tab releasably sealing said slit.
Claim 14
Dependent Claim
16 words
A system according to claim 1 including means for orienting said pouch within said sealed bag.
Claim 15
Dependent Claim
30 words
A system according to claim 13 in which said swab includes an absorbent head, and in which said means for orienting comprises means for retaining said pouch proximate said head.
Claim 16
Dependent Claim
58 words
A system according to claim 14 in which said pouch has a given width, and in which said means for retaining comprises a partial barrier formed in said bag intermediate opposite ends of said bag, said barrier having a gap for passage of said swab therethrough, said gap having a width dimension not greater than said given width.
Claim 17
Dependent Claim
22 words
A system according to claim 15 in which said barrier comprises a heat seal in front and rear films forming said bag.
Claim 18
Independent Claim
156 words
A method of impregnating and dispensing a swab located in combination with a liquid-filled frangible pouch in a sealed outer flexible bag comprising opposite sides and ends sealed along respective side and end edges thereof, the bag having an access location on one side located intermediate the side and end edges and extending laterally across a portion of said one side intermediate the side and end edges for allowing removal of the swab, comprising the steps of a. opening the pouch within the sealed outer bag to release the liquid from the pouch, b. impregnating the swab with liquid released within the sealed bag, c. opening the bag at the access location to form a dispensing slit in one wall of the bag intermediate the side edges of the bag, forming a reservoir in the bag when the bag lies on a side opposite said one side, and d. removing the swab through the dispensing slit.
Claim 19
Independent Claim
156 words
A method of impregnating and dispensing a swab located in combination with a liquid-filled frangible pouch in a sealed outer flexible bag comprising opposite sides and ends sealed along respective side and end edges thereof, the bag having an access location on one side located intermediate the side and end edges and extending laterally across a portion of said one side intermediate the side and end edges for allowing removal of the swab, comprising the steps of a. opening the pouch within the sealed outer bag to release the liquid from the pouch, b. impregnating the swab with liquid released within the sealed bag, c. opening the bag at the access location to form a dispensing slit in one wall of the bag intermediate the side edges of the bag, forming a reservoir in the bag when the bag lies on a side opposite said one side, and d. removing the swab through the dispensing slit.
Claim 20
Dependent Claim
32 words
A method according to claim 17 in which method step "a" includes applying pressure to the pouch to cause the liquid within the pouch to fracture the pouch to release the liquid.
Claim 21
Dependent Claim
37 words
A method according to claim 17 in which means is provided to pierce said pouch while sealed within said bag, and method step "a" includes using the pierce means to fracture the pouch to release the liquid.

45 words
A method according to claim 17 in which the access location includes a line of weakening, and method step "c" includes stretching the bag at the line of weakening to form the slit in the bag by severing the bag along the line of weakening.
Claim 23
Dependent Claim
40 words
A method according to claim 17 in which the slit is preformed in the bag and is overlain by a peel away tab sealing the slit, and method step "c" includes removing the peel away tab to expose the slit.
Claim 24
Dependent Claim
