ABSTRACT:
A blade holder and nozzle assembly connectable to a flexible container closure element such that when the blade holder and nozzle assembly is connected to the flexible closure a circular opening is formed in the flexible closure and surfaces on the blade holder and nozzle assembly and on the flexible closure are urged into sealing relation. The assembly comprises a hollow, tubular body having a shoulder extending around the interior thereof dividing the interior of the body into a threaded bore in the lower end of the body and a nozzle in the upper end of the body. A single cutting blade having a pointed end and a single cutting edge is secured to the shoulder and extends into the threaded bore such that as the body is threadedly secured to a flexible closure element, the cutting blade pierces the upper surface of the closure element and as the body is rotated the blade cuts a circular opening in the upper end of the closure element. The shoulder in the body moves into sealing engagement with the closure element about the periphery of the circular opening formed therein. Liquid from a container can be poured through the opening formed in the closure element and dispensed through the nozzle.
