An injection molding mechanism and method of its use for the formation in a single sequence of operations of weld-line free cylindrical container body portions having a central opening at one end. The central opening is formed by the removal of the central top sprue portion of the container body. The container body produced by this mechanism can be used as a pressurizable dispensing container.

Method for producing a weld-line free injection molded plastic container

A side dispensing-closure for a container wherein the dispensing-closure is made of a resilient plastic and includes a dispenser which is integral with a container cap for closing the container. The dispenser includes a recess in the top surface of the container cap for housing a dispensing orifice and a fluid passageway between the interior of the container and the dispensing orifice. A cover attached at one end of the recess encloses the dispenser orifice and fluid passageway and includes a plug extending from the underside of the top surface thereof which is mated with an opening in the passageway to open and close the passageway leading to the orifice when the cover is open or closed to provide a dispensing and non-dispensing position. The dispenser can be readily operated to dispense a material from the container while the cap is retained in place on the container.
