Latest Patents

One of Mierzwiak's latest patents is the "Pierce and Cut Closure." This invention is a cut and pierce closure molded from a rigid plastic material for a container whose open mouth is normally sealed by a thin membrane applied to the rim of the container. The closure is designed to be removably applied to the container in a closing orientation by interengaging helical threads on the exterior of the neck of the container and an annular skirt of the closure. To dispense the contents of the container, the closure is removed and reapplied in an inverted orientation. A flange extension of the closure skirt surrounds the rim of the container and serves to center the closure in its inverted orientation on the container. The top panel of the closure features a double-ended arcuate shoulder that engages the membrane when the closure is in its inverted orientation, maintaining tension in the portion of the membrane in contact with the shoulder. A sharp cutting element projects axially from the shoulder and functions to pierce the membrane when the closure is reapplied. This innovative design allows for the dispensing of the container's contents while ensuring that the severed membrane remains affixed to the rim, preventing it from dropping into the container.
