Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to metering medicine dosages and particularly to the need for supplying users with premeasured dosage packaging. More particularly, the present invention relates to child resistant premeasured packaging which will be convenient and efficient yet difficult for children to breach. Specifically, the present invention involves a child resistant, disposable, premeasured dosage spoon useful for liquid, powder, bead, slurry or other flowable medicine.




2. Information Disclosure Statement




The following patents relate to the state of the art in the field of disposable spoons for metered dosage medicine:




U.S. Pat. No. 5,988,459 to Nelson et al. describes a child-resistant package including a multilayered polymeric tray having a basin and a brim. The tray has a plastic structural layer and a bonding layer. A multilayered polymeric cover has a cross-oriented, tear-resistant layer, a bonding layer, and a moisture-barrier layer between the tear-resistant layer and the bonding layer of the cover. The bonding layer of the cover is sealed to the bonding layer of the brim of the tray to form a closed cavity between the tray and the cover.




U.S. Pat. No. 5,975,305 to Steven J. Barger describes a unit dose spoon having a bowl portion, a recessed handle portion communicating with the bowl portion. An upwardly extending pedestal is mounted in the recessed handle portion and is provided with an upwardly extending cutting blade on the top surface thereof. A container is integrally hinged to the free end of the handle portion and contains a unit dose of fluid such as medicine, which is sealed in the container by a rupturable plastic cover. When the container is folded forwardly toward the handle portion and pushed downwardly toward the pedestal, the blade thereon punctures the plastic cover to allow fluid to flow from the container into the recessed handle portion and into the bowl portion. The unit dose spoon is formed of molded plastic and is disposable.




U.S. Pat. No. 4,724,615 to Mackles et al. describes a medicine spoon having a spoon bowl with a handle, and a flat cover completely covering the bowl in a closed position in which the cover bears against the edge of the bowl. The cover has a handle attached to the bowl handle for pivotal movement between the closed and open positions, and the cover has an opening through which an amount of a foam product from a dispenser may be fed to the bowl in the closed position of the cover. The underside of the cover scrapes along the upper edge of the bowl for wiping the underside clean during movement of the cover to its open position. Stop shoulders in the form of continuous flanges are provided on the bowl and cover for both limiting the cover to its completely closed position and for preventing leakage of product through the cover when filling.




U.S. Pat. No. 1,474,443 to Robert B. Rhyne describes in a medicine spoon, the combination with a bowl portion and a handle therefor; of a cover for the bowl thereof and having an angularly disposed handle, the angular juncture of the cover and its handle being engaged with the handle of the spoon to form a fulcrum, and said handle of the cover being arranged in space relation to the spoon handle and adapted to be moved toward the spoon handle to cause said angular juncture to fulcrum and move the cover away from the bowl of the spoon.




Notwithstanding the prior art, the present invention is neither taught nor rendered obvious thereby.
