Blow Molding
A method of fabrication in which a warm plastic parison (hollow tube) is placed between the two halves of a mold (cavity) and, by using air pressure, the parison is forced to assume the shape of the cavity. The air pressure is introduced through the inside of the parison. The air pressure forces the plastic against the surface of the mold that defines the shape of the container.
Injection Molding
A molding procedure whereby a heat-softened plastic material is forced from a cylinder into a relatively cool cavity giving the article the desired shape.
Mold
The cavity or matrix into which the plastic composition is placed and from which it takes its form.
Amber

Closure
A devise used to seal off the opening of the bottle to prevent the loss of its contents.
Finish
The plastic forming the opening of a container and shaped to accommodate a specific closure.
Lug
A type of thread configuration designed so the thread segments are disposed equidistantly around a bottle neck (finish). The closure has matching portions that engage each of the thread segments.
