The system (100) includes a dispenser (102) defining a first reservoir (108) therein and comprising a check valve (112) communicating with the first reservoir (108) and an exterior of the dispenser (102). The system (100) also includes a refill cartridge (104) defining a second reservoir (128) therein and including a valve-piercing element (126) configured to be received through the check valve (112), such that, when the valve-piercing element (126) is received through the check valve (112), the second reservoir (128) of the refill cartridge (104) fluidly communicates with the first reservoir (108) of the dispenser (102) via the valve-piercing element (126). ## Claims ### Claim 1 A system for dispensing fluidic deodorant, comprising: a dispenser defining a first reservoir therein and comprising a first check valve communicating with the first reservoir and an exterior of the dispenser; and a refill cartridge defining a second reservoir therein and comprising a valve-piercing element configured to be received through the first check valve, such that, when the valve-piercing element is received through the first check valve, the second reservoir of the refill cartridge fluidly communicates with the first reservoir of the dispenser via the valve-piercing element, wherein the refill cartridge comprises a flexible pouch, wherein the refill cartridge comprises a second check valve to retain fluid in the second reservoir until the fluid in the second reservoir is at a predetermined pressure; and the fluidic deodorant, wherein the fluidic deodorant is a non-compressible fluidic deodorant. ### Claim 2 (depends on 1) The system of claim 1, wherein the valve-piercing element extends into the first reservoir of the dispenser when the valve-piercing element is received through the first check valve. ### Claim 3 (depends on 1) The system of claim 1, wherein the valve-piercing element comprises an elongate body defining a conduit therein in communication with the second reservoir, the elongate body defining an opening in communication with the conduit. ### Claim 4 (depends on 3) The system of claim 3, wherein the opening of the elongate body extends into the first reservoir when the valve-piercing element is received through the first check valve. ### Claim 5 (depends on 3) The system of claim 3, wherein at least a portion of the first check valve seals with the elongate body when the elongate body is received into the first check valve, so as to prevent fluid flow between at least a portion of the elongate body and the first check valve. ### Claim 6 (depends on 1) The system of claim 1, wherein the first check valve defines a resiliently expandable conduit, and wherein the valve-piercing element expands a diameter of at least a portion of the resiliently expandable conduit when the valve-piercing element is received through the first check valve. ### Claim 7 (depends on 1) The system of claim 1, wherein the dispenser further comprises a pressure relief valve communicating with the first reservoir. ### Claim 8 (depends on 7) The system of claim 7, wherein the pressure relief valve is configured to open when a pressure within the first reservoir of the dispenser meets or exceeds a predetermined threshold. ### Claim 9 (depends on 7) The system of claim 7, wherein the dispenser comprises an applicator in fluid communication with the first reservoir, and wherein the pressure relief valve and the first check valve are disposed on a bottom of the dispenser, opposite from the applicator. ### Claim 10 A refillable underarm deodorant dispensing system, comprising: a dispenser comprising: a housing defining a first reservoir therein configured to contain a fluid; an applicator coupled with the housing, such that at least a portion of the applicator is configured to rotate relative to the housing, the applicator being configured to receive the fluid from the first reservoir; a first check valve extending through a wall of the housing and communicating with the first reservoir, wherein the first check valve comprises a resilient body defining a first conduit extending therein, the first conduit having an open end communicating with an exterior of the housing and a sealing end communicating with the first reservoir, wherein the sealing end is biased toward a closed configuration in which fluid is prevented from traversing the first conduit; and a refill cartridge comprising: a second housing defining a second reservoir therein, wherein the second housing comprises a flexible pouch, wherein the refill cartridge comprises a second check valve to retain fluid in the second reservoir until the fluid in the second reservoir is at a predetermined pressure; and a valve-piercing element extending from the second housing, the valve-piercing element comprising a proximal end coupled with the second housing, a distal end, and an elongate body extending between the proximal end and the distal end, the elongate body defining a second conduit therethrough and an opening positioned on or near the distal end, the opening being in communication with the second reservoir via the second conduit, wherein the elongate body of the valve-piercing element is configured to be received through the first conduit of the resilient body of the first check valve to open the sealing end of the first check valve, such that, when the elongate body is received through the first conduit of the resilient body of the first check valve, the second reservoir of the refill cartridge fluidly communicates with the first reservoir of the dispenser via the second conduit of the elongate body of the valve-piercing element. ### Claim 11 (depends on 10) The system of claim 10, wherein the elongate body of the valve-piercing element of the refill cartridge expands and seals with at least a portion of the first conduit of the resilient body of the first check valve, when the valve-piercing element is received through the first check valve. ### Claim 12 (depends on 11) The system of claim 11, wherein the dispenser further comprises a pressure relief valve communicating with the first reservoir of the dispenser, the pressure relief valve being configured to release a gas at a predetermined pressure from the first reservoir to the exterior of the housing. ### Claim 13 (depends on 10) The system of claim 10, wherein said first reservoir is configured to house the fluid at a constant ambient pressure. ### Claim 14 (depends on 1) The system of claim 1, wherein the flexible pouch is movable between a sealed configuration when no pressure is applied to the refill cartridge and a fluidly open configuration when the predetermined pressure is applied to the refill cartridge. ### Claim 15 A kit, comprising: a dispenser defining a first reservoir therein and comprising a first check valve communicating with the first reservoir and an exterior of the dispenser; and a plurality of refill cartridges, each of said refill cartridges defining a second reservoir therein and comprising a valve-piercing element configured to be received through the first check valve, such that, when the valve-piercing element is received through the first check valve, the second reservoir of the refill cartridge fluidly communicates with the first reservoir of the dispenser via the valve-piercing element, wherein the refill cartridge comprises a flexible pouch, wherein the refill cartridge comprises a second check valve to retain fluid in the second reservoir until the fluid in the second reservoir is at a predetermined pressure, wherein each of said refill cartridges comprises a non-compressible fluidic deodorant.
