Blow molded plastic container having improved top load strength

摘要

A blow molded plastic container includes a main body portion having an upper surface and a finish portion that extends from the upper surface. A reinforcing strut is provided on the upper surface of the main body portion adjacent to the finish portion for providing increased structural rigidity and top load strength to the container. The reinforcing strut may be fabricated in a manner that promotes drainage of fluid from the container, such as by defining a downwardly sloping inner channel that leads to the finish portion when the container is inverted.

主权项

1. A blow molded plastic container, comprising:
a main body portion having a central longitudinal axis and an upper surface; a finish portion adapted to receive a closure, the finish portion being unitary with the main body portion and extending upwardly from the upper surface to define a maximum height; and a reinforcing strut defined in the upper surface, the reinforcing strut having a transition region proximate the finish portion and a generally planar top surface extending therefrom, the reinforcing strut increasing in height relative the upper surface with increasing distance from the transition region, wherein the reinforcing strut contacts the finish portion along at least 20% of the maximum height.
