Anatomy Of A BOTTLE Flashcards
The flat, circular top surface of the finish which
makes direct contact with the closure to form a
seal. It’s sometimes referred to as the “land.”
Sealing Surface
A spiral-shaped ridge on the finish of a bottle
intended to mesh with a similarly sized screw-type
closure to seal the container.
Thread
A horizontal ridge at the base of the finish used for
transferring the bottle from one part of the
production process to the next.
Neck Ring or Transfer Bead
The slight vertical ridge that runs through the neck ring
and the rest of the finish. It indicates where
two halves of the finish molds were joined.
Mold Seam
The main part of the bottle where the sidewalls are
usually (but not always) vertical.
Body
The entire lower part of the bottle below the
sidewalls. It includes the heel, base and
pushup.
Bottom
It may have letters and symbols
molded into it that indicate the number of the mold
cavity that produced the container and the
manufacturer. The manufacturer symbol is called a
“punt mark”.
Bottom
The manufacturer symbol is called a
Punt mark
The lower part of the bottle where the body
(sidewall) turns from vertical to horizontal.
Heel
It joins the sidewall to the bottom-bearing surface
and may have a small recessed spot that serves as a
registration device for labeling and decorating
equipment.
Heel
An inward dome in the center of the base. The
resulting ring around the outside of the bottom
ensures stability, providing an even bearing surface
upon which the bottle rests
Pushup:
The top part of the container, above the neck, shaped
to accommodate a specific closure.
Finish
The portion of the container that is above the shoulder
and below the finish. It is where the crosssection
of the bottle grows smaller to join the finish.
Neck
The part of the bottle that joins the wide main body
and the narrower neck.
Shoulder
A flat area on the body of the bottle that can accept
the application of a label.
Label Panel:
The bottom plate is the part of the mold that shapes
the bottom of the container. It is a slight
horizontal ridge formed in the joint between two parts
of the mold.
Mold Parting Line:
An even bearing surface that forms a ring around the
outside of the bottom upon which the bottle rests. On
glass containers, this ring usually is given a stippled
finish in the mold to mask scratches that occur during
handling
