Product Life Cycle

What has negatively impacted the creation of glass Coke bottles?

The production of plastic Coke bottles now make individuals look at glass bottles as a classic item.

What developments have impacted the design, sales, usability, or market status of the glass Coke Bottle?In the past, the item would hit the shelves at random occasions, but currently they are stocked in many stores year-round and can be easily found. The glass Coke bottle has always stayed the same since 1915 as no innovations have been made.

Premanufacture: Raw Material ExtractionGlass containers are commonly made with a combination of many oxides or oxygen-based compounds and are referred to as “soda-lime” glass. The combination of raw materials, such as sand, soda ash, limestone and cullet (recycled broken or waste glass used in glassmaking) creates glass containers that are durable, strong, inexpensive and that can be shaped easily. The goal is to use the most economical and high-quality raw materials available.

Premanufacture: Material Processing

Silica sand is obtained.

Sodium carbonate is added to the sand, as it lowers the temperature necessary to make glass suitable for

public use. However, it permits water to pass through the glass, so calcium oxide (limestone) is added to

negate this property. Oxides of magnesium and/or aluminum may also be added to make the glass more

durable.

Iron impurities in the sand make glass appear greenish, therefore they are removed for the production of

the coca-cola glass bottle.

Cullet also know as recycled, broken, or wasted glass is retrieved and added to the raw materials as it

reduces greenhouse gas emissions by lowering the temperature required for the melting process.

Generally, these additives take up no more than 26 to 30 percent of the glass mixture.

All materials are stored in silos, weighed, then combined and heated in a gas fired furnace (2800-3000

Degrees Fahrenheit ) until liquidation.

Manufacture: Component ManufactureThe materials are fed through one end of a furnace as a combustible mixture of natural gas and air creates the desired temperature slightly greater than 2800 degrees Fahrenheit.

As the materials melt and produce glass, it is then forced through a spout in the bottom of the furnace called an orpheus ring.

The glass is then cut by shears to create a “gob” of glass. Each “gob” is large enough to create one bottle.

At this stage, the glass is sent to the forming machine as compressed air transforms the “gobs” into a blank form, which is then blown into the final shape of the coke-bottle in a mold

The molded bottles are then coated in a thin layer of tin, afterwards they are annealed (A process to relieved the stress placed on glass during the cooling period).

The bottles are finally duracoated with a thin layer of polymer to provide them with a scratch resistant coating.

Manufacture: Assembly

The bottles are inspected before being filled.

As for the bottles that don’t meet requirements are broken down and reused.

Bottles that meet the Coca-Cola Company’s requirements are then filled and packaged to be distributed by bulk.

Product Delivery: Packaging and DistributionThe glass bottles are packaged in four different continents, Asia, Africa, South America and Europe. As they are then shipped out to many supermarkets, gas stations, restaurants etc.

Use: Installation & Use

Coca-Cola can have many uses as it can act as a sweetener, flavoring agent, or an just can be directly consumed or mixed with other sweets, foods, or beverages.

Use: Maintenance & Upgrading

The key to maintaining a glass coke bottle is to handle it carefully as for glass bottles of the Coca-Cola brand have been stored and treated as collectables by many individuals for decades.

Disposal

Glass bottles and jars are 100% recyclable and can be recycled endlessly without any loss in

purity or quality. The container and fiberglass industries collectively purchase 3 million tons

of recycled glass annually, which is then broken down (Cullet), remelted and repurposed for

use in the production of new containers and fiberglass products.
