Glass Bottle Glossary
Absolute volume |
The absolute volume of the container when
filled to the rim. |
ACL |
See Applied Ceramic Labeling |
Amber glass |
A brown-colored glass used principally for beer,
medicine and liquor containers. The color decreases the effect of some forms
of light which would be injurious to the contents of the container. |
Annealing |
A controlled temperature process in which glass is gradually
cooled in ovens or lehrs to avoid the creation of stresses and strains within
the glass due to natural or uneven cooling. The annealing temperature in
glass is about 1000 degrees F. |
Applied Ceramic Labeling (ACL) |
Colored lettering or design of a ceramic nature
fused onto bottles. Employs screen printing to transfer glass frit (pow-
dered glass colorant) to the surface of a bottle or glass container. The
design is fired, heated in a lehr, and becomes permanently fused. |
Bar top |
A closure with a cork lower and a usually an upper
made from plastic, metal or wood. It may also refer to the neck finish that
matches this type of closure. |
Batch |
The mixture of ingredients used to make the molten
glass. The batch for soda lime glass consists primarily of silica sand,
sodium carbonate (known as soda ash), calcium oxide (lime), magnesium oxide,
and aluminum oxide. |
Bevel |
The sloping edge of a container or part. A bevel
adds a short flat span at the junction of two sides of a container. |
Bottle Decoration |
All design aspects that are applied after the bottle
itself has been produced. This includes coloration, frosting, decal baking,
labeling, and any other modifications. |
Capsule |
Pre-printed, heatshrink foil or plastic tube that
fits over the neck of the bottle and closure and provides tamper evidence. |
Ceramic heat transfer labeling |
Similar to applied ceramic labeling, this is a
process that uses a printed decal affixed to the surface of the glass. The
glass is fired, heated in a lehr, and becomes permanently fused. |
Choked Neck |
A narrowed or constricted opening in the neck
of a container. |
Closure |
Any structure or device designed to close off the
opening of a container and prevent loss of its contents. |
Cobalt Glass |
A deep blue glass coloured by adding cobalt
compounds. |
Cold end |
The last stage in glass-container production which
consists of inspecting the containers for defects, labeling the containers,
and packaging the containers for shipment. |
Continuous Thread |
An uninterrupted protruding helix on the neck of a
container to hold a screw-type closure. Continuous thread finishes have GPI
finish designations in the 400 series. |
Crown Cap |
This is a crimped closure. Flutes are pressed into
the flaring skirt of a shallow metal disk, which holds an inner disk of
resilient lining material that forms the actual seal. |
Cullet |
Crushed recycled glass that is added to the glass
furnace |
Embossing |
Raised design or lettering on the surface of the
glass. |
Etching |
A method of frosting the surface of a glass bottle
by exposing it to a solution of concentrated acid. |
Fill volume (Fill point) |
The level to which a container must be filled to
furnish a designated quantity of the contents. |
Flint glass |
Flint glass is optical glass that has relatively
high refractive index. The term flint derives from the flint nodules found in
the chalk deposits of southeast England that were used as a source of high
purity silica. |
Frosting |
A method of bottle decoration that gives the surface
of the glass a frosted look. Frosting can be accomplished by decal labeling
or by acid etching. |
Gob |
A cylindrical mass of molten glass that is cut off
as it extrudes from the furnace. The gob is directed into the mold
where it is shaped. |
GPI |
Glass Packaging Institute – an American standards
organization which helps set standards for bottle necks and closures. |
Hot end |
The first stage of glass-container production which
typically employs high amounts of heat to produce and shape a glass
container. |
Internal Treatment (dealkalization) |
A treatment to improve the chemical resistance of
the inside surface, usually accomplished through the injection of a sulfuror
fluorine containing gas mixture into bottles at high temperatures. The
treatment renders the container more resistant to alkali extraction, which
can cause increases in product pH, and in some cases container degradation. |
Lehr |
A continuous-belt oven for the annealing of glass,
and for fusing of ce- ramic color onto glass. |
Lug cap |
Interrupted thread finishes with the GPI finish
number designations in the 2000 series. Lug caps are often used for jars and
for ketchup bottles. |
Metallized Closure |
Plastic closures with a surface deposit of aluminum
coated with lac- quers to render a decorative metallic effect. |
Neck finish |
The configuration of a container top shaped to
accommodate a closure. |
Parison |
Preliminary form of the final container that is
produced after the gob gets shaped in the first stage mold. |
Pilferproof Seal |
A seal that cannot be opened without partially destroying
the cap or otherwise showing evidence of tampering. |
Punt |
The concave indentation at the bottom of a bottle -
most commonly found on wine bottles. |
Reshipper Carton |
Shipping container in which empty unit containers
are received and intended to be used as shipping containers for the product
packaged in the unit containers. |
ROPP cap |
Rolled On Pilfer Proof cap |
Sleeve Label |
See Capsule |
Soda-lime glass |
See flint glass |
Spray Coloration |
A method of adding color to the surface of a bottle
by spraying the surface and then baking the color into the glass. Spray
coloration can be done in a multitude of colors, intensities and gradations. |
Stelvin finish/closure |
The Stelvin(R) neck finish can be found on some
glass wine bottles. It is a screw thread finish designed to accomodate the
Stelvin(R) closure, an aluminium cap with a tamper evident breakaway band.
Offers prod- uct preservation, a modern look and practicality. |
Tamper evidence |
A closure or liner system incorporating a feature
that visually indicates if the closure has been removed or the product has
been exposed. Removal of the closure or liner system activates the indicating
feature. |
Transfer Bead |
A projecting bead on the outer surface of some glass
containers, usu- ally just below the finish, to provide a surface of
engagement for the jaws of handling devices during manufacture. |
Type I glass |
A borosilicate glass which releases the least amount
of alkali. It is commonly used for pharmaceutical or fine chemical products
that are sensitive to PH changes. |
Type II glass |
A soda lime glass (Type III) that has been
de-alkalized by treating the interior surfaces to eat away the alkali on or
near the glass surfaces. The undesirable characteristic of Glass is that the
treating etches the surface, causing a frosted appearance. |
Type III glass |
A soda lime glass and the most common in use. Type
III is compatible with most items: food, beverages, common chemicals, etc. |
