Abstract
The present invention is a mechanically operating device used for packaging and applying a product. A molded product traverses through a barrel as an actuator sleeve is rotated. The actuator sleeve rotates an actuator, propelling a driver through the barrel. The driver is keyed into the barrel using a clutch washer—the clutch washer prevents the rotation of the driver. Mechanical actuating splines on the actuator engage the threads of the driver. The forward motion of the driver transversely pushes a cup out from an orifice of the barrel. The molded product is fitted within the cup. A cap is hermetically sealed to a barrel to create dynamic vapor chamber that prevents any contamination or alteration of the molded product. Primary and secondary seals between the barrel and the cap as well as between the cup and the barrel maintain the airtight feature of the dynamic vapor chamber.
