Abstract
A tumbler is formed of injected plastic material that has different directional strengths by injecting the plastic material somewhat tangentially to cause the plastic material to move peripherally in the rim defining portion of the mold cavity in order to have the weaker directional strength also extend peripherally to thereby increase the tumbler's resistance to lengthwise splitting from the rim to the bottom and in which the mold is vented into a cooling passageway.
