A dispenser includes a flexible outer tube, a flexible inner tube in the outer tube, a plunger switch, a spring biased valve assembly having a rotation actuator, and a cap. After cap removal, a rotation of the rotation actuator enables an extrusion of a material in the outer tube out of the spout of the valve assembly via a material dispensation tunnel of the rotation actuator when the outer tube is depressed. A further rotation of the rotation actuator enables an extrusion of a material in the inner tube out of the spout of the valve assembly via the material dispensation tunnel when the outer tube is depressed. A still further rotation of the rotation actuator enables a mixed extrusion of the materials in both the inner and outer tubes out of the spout of the valve assembly via the material dispensation tunnel when the outer tube is depressed.

1. A dispenser comprising: a flexible outer tube comprising a spout, external threads proximate to the spout, an annular protrusion between the external threads and the spout, an indicating mark proximate to one end of the external threads, and an internal space;a flexible inner tube disposed in the outer tube and comprising an inner space, a front extension, a protuberance in the front extension, a passageway on a front edge of the front extension, and a channel member through the protuberance and being in communication with the inner space of the inner tube and a space in front of the inner tube;a plunger switch comprising a hollow cylindrical body, a shank projecting forward from a center of a front end of the cylindrical body, a molded key on a surface of the shank, two passages on a front edge of the cylindrical body, and two channel members on the front end of the cylindrical body proximate to the shank wherein the channel members are in communication with an internal space defined by the cylindrical body and a space in front of the plunger switch, and the cylindrical body is fitted in the front extension of the inner tube;a valve assembly comprising a cylindrical rotation actuator including a stepped-diameter stem projecting from a front end, an inward extending rim on a rear end, an internal cylindrical member including a material dispensation tunnel through both the cylindrical member and the stem, an axial slot on an inner surface of the cylindrical member, and an indication unit on an outer surface of the rotation actuator; and a spout releasably secured onto the stem wherein the key of the plunger switch slides in the slot so that both the plunger switch and the rotation actuator are capable of co-rotating;an elastic member put on the spout of the outer tube; anda cap comprising internal threads on an inner surface adjacent to a rear opening, and an engagement surface adjacent to the internal threads,wherein in a closed state of the dispenser the internal threads of the cap are secured to the external threads of the outer tube with the elastic member being biased between a blind end of the rotation actuator and the protrusion of the outer tube, and the material dispensation tunnel being blocked by the shank; andwherein in response to unfastening and removing the cap the elastic member expands to push the rotation actuator until the rim is stopped by the protrusion of the outer tube with the material dispensation tunnel being not blocked by the shank such that:a rotation of the rotation actuator communicates one of the passages with the passageway so as to extrude a material contained in the outer tube out of the spout of the valve assembly via the passageway, one of the passages, and the material dispensation tunnel when the outer tube is depressed;a further rotation of the rotation actuator communicates one of the channels with the channel member so as to extrude a material contained in the inner tube out of the spout of the valve assembly via the channel member, one of the channels, and the material dispensation tunnel when the outer tube is depressed; anda still further rotation of the rotation actuator communicates both the other passage with the passageway and the other channel with the channel member so as to extrude the material in the outer tube out of the spout of the valve assembly via the passageway, the other passage, and the material dispensation tunnel and extrude the material in the inner tube out of the spout of the valve assembly via the channel member, the other channel, and the material dispensation tunnel respectively when the outer tube is depressed with the materials of both the inner and outer tubes being mixed in the material dispensation tunnel. 2. The dispenser of claim 1, wherein the indication unit comprises first, second, third, and fourth indication marks; and wherein a first rotation of the rotation actuator points the indicating mark at the first indication mark with both the inner and outer tubes being blocked by the plunger switch, a second rotation of the rotation actuator points the indicating mark at the second indication mark with the material in the outer tube communicating with both the plunger switch and the valve assembly for dispensation and the inner tube being blocked by the plunger switch, a third rotation of the rotation actuator points the indicating mark at the third indication mark with the materials in both the inner and outer tubes communicating with both the plunger switch and the valve assembly for dispensation, and a fourth rotation of the rotation actuator points the indicating mark at the third indication mark with the material in the inner tube communicating with both the plunger switch and the valve assembly for dispensation and the outer tube being blocked by the plunger switch. 3. The dispenser of claim 1, wherein the elastic member is a torsion spring. 4. The dispenser of claim 1, wherein the material in the inner space of the outer tube is a viscous first cosmetic material. 5. The dispenser of claim 1, wherein the material in the inner space of the inner tube is a viscous second cosmetic material. 6. The dispenser of claim 1, wherein the outer tube further comprises an annular flange on a stepped-diameter inner surface of the spout. 7. The dispenser of claim 1, wherein the cylindrical body of the plunger switch comprises an annular flange on an end surface adapted to engage with a rear end of the material dispensation tunnel. 8. The dispenser of claim 1, wherein the valve assembly further comprises a ring having two opposite elongated apertures on a surface, and wherein the rotation actuator further comprises two opposite pegs on an outer surface, the pegs being slidably disposed in the elongated apertures when the ring is mounted on the rotation actuator so as to cause the dispensation by rotating the ring with the pegs sliding in the elongated apertures.
