Class Information
Number: 425/564
Name: Plastic article or earthenware shaping or treating: apparatus > Female mold and charger to supply fluent stock under pressure thereto in fluid-tight relationship (e.g., injection mold, etc.) > With means between charger and mold to cut off flow of fluent stock (e.g., needle valve, baffle, etc.) > Nozzle valve
Description: Apparatus including, along the stock material passage, a coupling between the forcing means and the shaping cavity wherein a projection is provided from the structure extending from the forcing means and a corresponding pocket is formed in the structure extending to the shaping cavity, such that the projection is adapted to sealingly fit into the pocket; wherein the blocking means is positioned in the projection, in the vicinity of the portion to be received by the pocket.
