A hand held blow molded plastic bottle having a vent passage extending along the interior of the bottle shoulder from the top of the body to the bottom of the neck. During pouring, air flows through the vent passage to a vacuum produced pocket in the bottle and liquid flows from the bottle in a continuous, controllable and rapidly laminar stream.

A hand held blow molded plastic bottle with improved pour characteristics, said bottle having a continuous and handle-free outer surface generally symmetrical about an axis and including a generally cylindrical body easily gripped in a single hand for manipulation and pouring of liquid out through the mouth; a base on the bottom of the body; a shoulder on the top of the body; a generally cylindrical neck on the top of the shoulder; a generally cylindrical neck flash on the top of the neck, the neck flash having a diameter less than the diameter of the neck; a radial inward step joining the neck to the neck flash; a thread on neck flash; a dam partially closing the interior of the neck at the radial inward step, the dam and the neck defining a pouring mouth communicating with the interior of the bottle, an integral vent tube extending along the one side of the neck and shoulder and having an upper mouth opening through the dam a distance from the pouring mouth and facing outwardly of the bottle and a lower mouth opening into the interior of the body; a continuous weld seam joining the length of the vent tube to the shoulder and neck of the bottle without breaks extending through the weld seam, the vent tube having an outer wall spaced from the axis of the bottle a distance approximately equal to the distance the surface of the neck and shoulder on the opposite side of the bottle from the outer wall is spaced from the axis of the bottle, a pair of angled interior walls joined to and extending to either side of the weld seam along the length of the vent tube between the upper and lower mouths, said interior walls joining the outer wall to the weld seam at the shoulder so that the shoulder portion of the vent tube is generally triangular in transverse cross section, and a pair of opposed side walls extending along the neck, said opposed side walls joining the outer wall to the interior walls at the neck so that the neck portion of the vent tube is generally pentagonal in transverse cross section, and a pair of vee-shaped recesses each extending along one side of the weld seam between the ends of the vent tube.
