Abstract
An applicator for dispensing a solution having two or more components includes a hollow body having a head provided at one end of the hollow body for dispersion of the solution and a breaking mechanism attached to the hollow body. The breaking mechanism includes at least one projection extendable into an interior of the hollow body. The applicator further includes a plurality of ampoules placed in the interior of the hollow body. The plurality of ampoules contains the two or more components. Upon activation of the breaking mechanism, the at least one projection applies a force to the plurality of ampoules such that the plurality of ampoules break and release the two or more components to form the solution.
Claims15
A method for storing, mixing, and applying a solution having a first component and a second component which inhibits exposure of the first and second components to air and moisture until just prior to application, said method comprising:
- hermetically sealing the first component within a first at least one ampoule;
- hermetically sealing the second component within a second at least one ampoule;
- disposing the first at least one ampoule and the second at least one ampoule within a hollow body, the hollow body having:
- a head for dispersion of the solution;
- a first breaking mechanism having a projection extendable into an interior of the hollow body;
- and
- a second breaking mechanism, the first breaking mechanism and the second breaking mechanism disposed on a side of the hollow body, the first breaking mechanism aligned with the second breaking mechanism;
- activating the first breaking mechanism such that the projection applies a force to break the first at least one ampoule and the second breaking mechanism to break the second at least one ampoule and release the first and second components from the first at least one ampoule and the second at least one ampoule;
- and
- topically applying the solution having the first and second components through the head.
A method for storing, mixing, and applying a solution having a first component and a second component which inhibits exposure of the first and second components to air and moisture until just prior to application, the first component being hermetically sealed within a first at least one ampoule, the second component being hermetically sealed within a second at least one ampoule, the first at least one ampoule and the second at least one ampoule disposed within a hollow body having a head for dispersion of the solution, a first breaking mechanism having at least one projection extendable into an interior of the hollow body to break the first at least one ampoule, and a second breaking mechanism to break the second at least one ampoule, the first breaking mechanism configured to rotate about a first pivot point in a plane in a first direction and the second breaking mechanism configured to rotate about a second pivot point in the plane in a second direction opposite the first direction, the first breaking mechanism and the second breaking mechanism disposed on a side of the hollow body, the first breaking mechanism aligned with the second breaking mechanism, the method comprising:
- activating the first breaking mechanism such that the at least one projection applies a force to break the first at least one ampoule and the second breaking mechanism to break the second at least one ampoule and mix the first and second components from the first at least one ampoule and the second at least one ampoule;
- and topically applying the solution having the first and second components through the head.
