Metered dose applicators that irradiate a portion of light sensitive product. When a dropper applicator is secured to a reservoir, a usable volume inside the dropper is reduced. As the dropper is removed from the reservoir, the usable volume in the dropper increases, creating a suction within the dropper that draws product into the dropper from the reservoir. When the dropper is off the reservoir, then a button that is accessible to a user is used to increase and decrease the size of the usable volume. The button also turns on a light that is effective to activate the product as it is being dispensed from the dropper.

1. A metered dose applicator comprising: a container for holding a flowable product;a closure that can be seated and unseated from the container;a dropper having a central longitudinal axis and a usable volume, wherein the dropper slides along the central longitudinal axis relative to the closure when the closure is being seated or unseated from the container;wherein a negative pressure is created in the dropper as the closure is being unseated from the container. 2. The applicator of claim 1 further comprising: a flowable product in the container, wherein a portion of the flowable product is drawn into the usable volume of the dropper as a result of the negative pressure in the dropper; anda light source that is able to shine on the portion of flowable product when the portion of flowable product is in the usable volume. 3. The applicator of claim 1 wherein the size of the usable volume can change. 4. The applicator of claim 3 wherein the size of the usable volume increases as the closure is being unseated from the container, and decreases as the closure is being seated onto the container. 5. The applicator of claim 3 further comprising: a piston that fits inside the dropper, such that: the piston and dropper can slide up and down relative to each other;a water tight seal is provided between a portion of the dropper and a portion of the piston; anda first spring that compresses and elongates as the piston and dropper slide relative to each other. 6. The applicator of claim 5 wherein the size of the usable volume increases as the piston slides up relative to the dropper, and decreases as the piston slides down relative to the dropper. 7. The applicator of claim 6 further comprising: a flowable product in the container, wherein a portion of the flowable product is drawn into the usable volume of the dropper as the piston slides up relative to the dropper, and a dose of flowable product flows out of the usable volume as the piston slides down relative to the dropper; anda light source that is able to shine on the portion of flowable product when the portion of flowable product is in the usable volume. 8. The applicator of claim 7 where in the size of the dose is between 0.1 mL and 10 mL. 9. The applicator of claim 7 wherein the light source is housed in a portion of the piston, and the piston is transparent or translucent to a specific wavelength of light emitted by the light source. 10. The applicator of claim 9 further comprising: a power source;an on and off switch; andelectrical connections between the light source, the power source and the switch, such that when the switch is closed, power flows from the power source to the light source and when the switch is open, power does not flow from the power source to the light source. 11. The applicator of claim 10 further comprising a button accessible by a user, that is able to close and open the on and off switch in cooperation with a second spring, and that is able to lower and raise the piston relative to the dropper, in cooperation with the first spring, wherein the piston is lowered only after the on and off switch is closed. 12. The applicator of clam 10 wherein the power source is one or more batteries housed in the piston, and the batteries are removable or replaceable. 13. The applicator of claim 10 wherein the light source is one or more light emitting diodes having a peak wavelength and a power output, wherein at least 25% of the power output of the one or more light emitting diodes is directed into cone whose central axis coincides with the longitudinal axis of the dropper, the cone having an apex angle of 15° to 90°. 14. The applicator of claim 13 wherein 50%-60% of the power output is directed into cone with an apex of 15° to 30°, and the peak wavelength of light is between 315 nm and 1400 nm. 15. A dropper applicator according to claim 1 wherein the container contains a light sensitive product that can be activated by a light source that emits a specified wavelength of light. 16. The dropper applicator according to claim 15 wherein the light sensitive product comprises a molecule that is susceptible to photodecomposition. 17. The dropper applicator according to claim 16 wherein the molecule is a photoinitiator. 18. The dropper applicator according to claim 17 wherein the photoinitiator is benzoin, a peroxide, an azo-compound, nitrogen dioxide, or combinations thereof. 19. The dropper applicator according to claim 15 wherein the light sensitive product is activated by a light source having a peak wavelength between 100 nm and 390 nm. 20. The dropper applicator according to claim 19 wherein the light sensitive product is activated by a light source having a peak wavelength between 100 nm and 280 nm. 21. The dropper applicator according to claim 19 wherein the light sensitive product is activated by a light source having a peak wavelength between 280 nm and 315 nm. 22. The dropper applicator according to claim 19 wherein the light sensitive product is activated by a light source having a peak wavelength between 315 nm and 390 nm. 23. The dropper applicator according to claim 15 wherein the light sensitive product is activated by a light source having a peak wavelength between 390 nm and 750 nm. 24. The dropper applicator according to claim 15 wherein the light sensitive product is activated by a light source having a peak wavelength between 750 nm and 1,400 nm.
