A portable personal dispenser comprising: (a) a personal dispenser refill unit including: a collapsible container having an interior volume holding a fluid, a collapsible dosing chamber communicating with said fluid in said container, and an outlet path fluidly communicating with said collapsible dosing chamber and communicating externally of said interior volume of said container, wherein operating said collapsible dosing chamber dispenses a dose of said fluid through said outlet path and out at an exit of said outlet path, whereby said interior volume of said collapsible container decreases by the volume of said dose; and (b) a handheld refill unit casing comprising: a housing defining an interior retaining said refill unit, an exit opening in said housing communicating with said outlet path such that fluid dispensed out said exit of said outlet path also exits said housing through said exit opening, a pump opening in said housing, a contour extending into said interior of said housing to urge said collapsible dosing chamber to be positioned in and aligned with said pump opening when said refill unit is retained in said container such that said collapsible dosing chamber is operated by being manipulated at said pump opening, whereby said contour maintains the positioning and alignment of said collapsible dosing chamber with said pump opening as said interior volume of said collapsible container decreases, and a pump lock having a lock position and an unlock position, wherein, when in said lock position, said collapsible dosing chamber cannot be manipulated through said pump opening, and, when in said unlock position, said collapsible dosing chamber can be manipulated through said pump opening to dispense said fluid in said container.
