The sprayer device utilizes a friction held piston that fires automatically upon full depression of the firing cap. A user may procure a monodose of medicine by (i) unlocking a child resistant mechanism; (ii) applying compressive force against the firing cap to first compress the spring and then to push the piston out of a friction area such that the spring causes the distal end of the piston to break the medicine container to drive medicine through the spray nozzle. The device includes a tear-away child resistant outer locking mechanism. Different length stops meter the amount of medicine dispensed. A two cap plug cap on the proximal and distal ends of the medicine package act as pistons. A piercer attached to a proximal end of the monodose medicine package moves upwardly when the piston is fired to pierce the medicine package and to drive medicine through the spray nozzle.
