A refillable cosmetic compact with an engaged configuration that permits a cosmetic product to be retained by the cosmetic compact and a disengaged configuration that permits the cosmetic product to be inserted into and removed from the cosmetic compact, wherein the cosmetic compact comprises: a product base insert with a floor and a sidewall wherein the floor and the sidewall define a cavity for receiving the cosmetic product; a base structure with a floor, an outer wall structure that projects from an outer portion of the floor, an inner wall structure that projects from an inner portion of the floor, and a cavity for receiving the product base insert, wherein the inner wall structure defines an actuation opening that passes through the base structure and wherein the actuation opening is open to the product base insert; wherein the product base insert is repositionable in relation to the base structure between an engaged configuration within the cavity that permits a cosmetic product to be retained and a disengaged configuration wherein the cosmetic product can be released from or inserted into the cosmetic compact; and wherein the product base insert can be ejected from the engaged configuration to the disengaged configuration by a pressing on the product base insert through the actuation opening that passes through the base structure, characterized in that the refillable cosmetic compact has a longitudinal direction and wherein the base structure retains a plurality of resiliently deflectable catch members that project generally in the longitudinal direction from the floor of the base structure, wherein the product base insert has a corresponding plurality of apertures for receiving the catch members, wherein a converging surface is retained by the product base insert in relation to each aperture, wherein each converging surface has a sloped portion disposed at a distal portion of the aperture that converges toward a longitudinal centerline of the product base insert, and wherein the converging surfaces are positioned to engage distal portions of the catch members as the product base insert is repositioned from the disengaged configuration to the engaged configuration to induce a deflection of the catch members laterally inwardly and to permit a deflection of the catch members laterally outwardly as the product base insert is repositioned from the engaged configuration to the disengaged configuration. a product base insert with a floor and a sidewall wherein the floor and the sidewall define a cavity for receiving the cosmetic product; a base structure with a floor, an outer wall structure that projects from an outer portion of the floor, an inner wall structure that projects from an inner portion of the floor, and a cavity for receiving the product base insert, wherein the inner wall structure defines an actuation opening that passes through the base structure and wherein the actuation opening is open to the product base insert; wherein the product base insert is repositionable in relation to the base structure between an engaged configuration within the cavity that permits a cosmetic product to be retained and a disengaged configuration wherein the cosmetic product can be released from or inserted into the cosmetic compact; and wherein the product base insert can be ejected from the engaged configuration to the disengaged configuration by a pressing on the product base insert through the actuation opening that passes through the base structure, characterized in that the refillable cosmetic compact has a longitudinal direction and wherein the base structure retains a plurality of resiliently deflectable catch members that project generally in the longitudinal direction from the floor of the base structure, wherein the product base insert has a corresponding plurality of apertures for receiving the catch members, wherein a converging surface is retained by the product base insert in relation to each aperture, wherein each converging surface has a sloped portion disposed at a distal portion of the aperture that converges toward a longitudinal centerline of the product base insert, and wherein the converging surfaces are positioned to engage distal portions of the catch members as the product base insert is repositioned from the disengaged configuration to the engaged configuration to induce a deflection of the catch members laterally inwardly and to permit a deflection of the catch members laterally outwardly as the product base insert is repositioned from the engaged configuration to the disengaged configuration.
