A method for inspecting a blow molded container having a finish, a base, a body between the finish and base, and etching at the base, the method comprising:
- identifying where on the base the etching is located;
- designating the base as accurately blow molded if the etching is located at a predetermined location of the base;
- and
- designating the base as not accurately blow molded if the etching is not located at the predetermined location of the base.
A container formed from a preform by stretch blow molding, the container comprising:
- a finish at a first end of the container, the finish configured to cooperate with a closure to close the container;
- a base at a second end of the container that is opposite to the first end;
- a body between the finish and the base;
- and
- an etched portion of the base, etching of the etched portion is a visual indicator configured to show whether the base is accurately blow molded or not accurately blow molded;
- wherein:
- when the etching is at a predetermined location of the base, the base is accurately blow molded;
- and
- when the etching is not at the predetermined location of the base, the base is not accurately blow molded.
A preform configured to form a container by stretch blow molding, the preform comprising:
- a finish portion at a first end of the preform, the finish portion is a container finish of the container;
- a base portion at a second end of the preform that is opposite to the first end of the preform, the base portion configured to form a container base of the container;
- a body portion between the finish portion and the base portion, the body portion configured to form a body of the container;
- and
- an etched portion of the base portion including etching, the etching is a visual indicator configured to show when the container base is accurately blow molded and when the container base is not accurately blow molded;
- wherein:
- when the etching is at a predetermined location of the container base, the container base is accurately blow molded;
- and
- when the etching is not at the predetermined location of the container base, the container base is not accurately blow molded.
