Title: A METHOD OF MOLDING A CONTAINER INCORPORATING SURFACE INDICIA AND THE CONTAINER
Abstract:
A method of forming a container (1) and a container (1) formed thereby. A preform (2), having a generally cylindrical body (60, 8) extending between a closed end (12) and an open mouth, is placed within a mold (20, 22) having surfaces corresponding in shape to the desired container (1). An incompressible medium, which is the end product that remains in the molded container (1), is injected under pressure into the preform (2). Under the influence of the incompressible medium, the preform (2) is expanded into contact with the surfaces defining the cavity, simultaneously forming and filling the container (1). During expanding of the preform (2), portions of the plastic material are forced into a series of recesses (72) defined in the cavity surface (82, 85). With the incompressible medium contained therein, the container (1) is removed from the mold (20, 22) and including a series of raised dots corresponding to the series of recesses (72) defined in the cavity surface (82, 85).
