1. A system for applying a fluid, comprising: a packet containing a fluid, the packet comprising: first and second opposing packet sides defining therebetween a sealed space containing the fluid;a frangible area configured to rupture upon compressing the packet to release the fluid from the packet; anda collapsibility feature enabling the first packet side of the packet to invert from a convex position to a concave position upon compressing the packet so that the formerly sealed space is substantially completely collapsed; andan applicator device comprising: a handle having a proximal end and a distal end, the handle comprising: a receptacle at the proximal end of the handle, the receptacle configured to receive the packet of the fluid and facilitate expulsion of the fluid from the packet;a flexible lid configured to sealingly enclose the packet within the receptacle and configured to deflect in response to application of exterior pressure enabling application of the exterior pressure to the packet when disposed within the receptacle to thereby compress the packet to release the fluid from the packet;a base extending radially outwards at a non-zero angle from the distal end of the handle and configured to direct flow of the released fluid, the base including a distal opening and an outer wall projecting transversely outwards from the base and circumferentially disposed about the distal opening; andan applicator pad configured to be coupled to the base, in fluid communication with an interior portion of the receptacle, wherein a portion of the pad is inserted within the distal opening of the base and a portion of the pad is wrapped around the outer wall to circumscribe the portion of the pad within the distal opening. 2. The system of claim 1, wherein the receptacle has a substantially round shape. 3. The system of claim 2, wherein a central receptacle axis through the substantially round shape of the receptacle is oriented at an angle relative to an axis perpendicular to a plane including the base. 4. The system of claim 3, wherein the angle is approximately 90 degrees. 5. The system of claim 3, wherein the packet has a substantially round shape that is configured to fit concentrically within the substantially round shape of the receptacle. 6. The system of claim 5, wherein the receptacle and the packet have corresponding orienting features that orient the packet with respect to the receptacle. 7. The system of claim 6, wherein the orienting features comprise a structure on the receptacle that deviates from the substantially round shape of the receptacle and a corresponding structure on the packet that deviates from the substantially round shape of the packet. 8. The system of claim 7, wherein the orienting features comprise corresponding protrusions on the receptacle and the packet. 9. The system of claim 8, wherein the protrusion on the receptacle is configured to orient the packet with the protrusion of the packet positioned toward the base. 10. The system of claim 9, wherein the protrusion on the packet comprises the frangible area of the packet. 11. The system of claim 5, wherein the first packet side comprises a first central portion and a first peripheral portion, and the second packet side includes a second central portion and a second peripheral portion; wherein the first and second packet sides of the packet are sealed to each other at a junction between the first peripheral portion and the second peripheral portion; andwherein the first central portion has a smaller diameter than the second peripheral portion, thereby forming the collapsibility feature. 12. The system of claim 1, wherein the lid is sealingly attached to a rim of the receptacle using an ultrasonic weld. 13. The system of claim 1, wherein the applicator device comprises at least one venting feature configured to allow air flow into or out of the receptacle. 14. The system of claim 13, wherein the venting feature comprises an area at a junction between the flexible lid and the receptacle that is left unsealed. 15. The system of claim 1, wherein the packet contains a fluid comprising a topical antiseptic. 16. The system of claim 15, wherein the topical antiseptic comprises at least one active ingredient chosen from ethanol, isopropyl alcohol, other alcohols, and combinations thereof; benzalkonium chloride; benzethonium chloride; chlorhexidine gluconate; chloroxylenol; cloflucarban; flourosalan; hexachlorophene; hexylresorcinols; iodine containing compounds; biguanide derivatives (or a salt thereof); povidone iodine; povidone iodine with alcohol, ethanol, isopropyl alcohol, other alcohols, and combinations thereof. 17. The system of claim 15, wherein the fluid further comprises a polyoxyethylene (POE)-based nonionic surfactant. 18. The system of claim 17, wherein the nonionic surfactant is at least one surfactant selected from Poloxamer 124, POE (9) lauryl ether, and POE (10) lauryl ether. 19. The system of claim 15, wherein the topical antiseptic comprises a biguanide derivative or a salt thereof. 20. The system of claim 19, wherein the biguanide derivative or salt thereof is olanexidine [1-(3,4-dichlorobenzyl)-5-octylbiguanide] or a salt thereof. 21. The system of claim 20, wherein the topical antiseptic comprises olanexidine gluconate. 22. The system of claim 19, wherein the biguanide derivative or a salt thereof is present at a concentration of about 0.05 to about 5.0% (w/v of biguanide base). 23. The system of claim 15, wherein the fluid further comprises a polyoxyethylene-based nonionic surfactant at a concentration of about 0.05 to about 16% (w/v). 24. The system of claim 1, wherein the applicator device is provided in ready to use form, wherein the packet is sealed within the receptacle and the applicator pad is attached to the base.
