TODAY’S PATENT – NUT OPENER
Nut Opener invention pertains to a novel approach for effortlessly splitting challenging pistachio nuts that are only slightly open. The design revolves around a singular pointed splitting wedge-shaped tooth situated on an upper jaw. This inventive tooth configuration yields a remarkable 4-fold increase in force and mechanical advantage.
This heightened leverage enables the efficient engagement and splitting of even problematic pistachios possessing minimal fissures on their rear side. Notably, the tooth can be skillfully angled and honed, prompting the nut to be drawn into the splitter due to the advantageous alignment of the tooth as it is inserted into the nut’s notch.
Invented by John W. Jessen and applied for patent grant in 2012. The application was granted patent on 13-10-2015 with the patent no. US9155424B2. As the tooth advances through the notch, the rounded, perpendicular surfaces flanking the splitter tooth permit the shell halves of the nut to glide smoothly. This interaction maintains the nut’s structural integrity during the splitting process.
