A system for applying a fluid, comprising: a packet containing a fluid, the packet comprising: first and second opposing packet sides (42, 44) defining therebetween a sealed space containing the fluid; 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; a frangible area configured to rupture upon compressing the packet to release the fluid from the packet; and a 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, wherein the first central portion has a smaller diameter than the second peripheral portion, thereby forming the collapsibility feature; and an 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 base oriented at an angle relative to the receptacle and configured to direct flow of the released fluid, the base including an outer portion defining a distal opening; and an applicator pad configured to be coupled to the base, in fluid communication with an interior portion of the receptacle via the distal opening of the base, 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 portion. a packet containing a fluid, the packet comprising: first and second opposing packet sides (42, 44) defining therebetween a sealed space containing the fluid; 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; a frangible area configured to rupture upon compressing the packet to release the fluid from the packet; and a 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, wherein the first central portion has a smaller diameter than the second peripheral portion, thereby forming the collapsibility feature; and first and second opposing packet sides (42, 44) defining therebetween a sealed space containing the fluid; 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; a frangible area configured to rupture upon compressing the packet to release the fluid from the packet; and a 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, wherein the first central portion has a smaller diameter than the second peripheral portion, thereby forming the collapsibility feature; and 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 base oriented at an angle relative to the receptacle and configured to direct flow of the released fluid, the base including an outer portion defining a distal opening; and an applicator pad configured to be coupled to the base, in fluid communication with an interior portion of the receptacle via the distal opening of the base, 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 portion.
