In this guide, we’ll explore the design features, patent marks, and production details. These elements will help you figure out when your Coke bottle was made.
Historical Evolution of Coca-Cola Bottles
The Coca-Cola bottle has changed a lot since the late 1800s. It went from early Hutchinson bottles to the modern contour design. This shows the brand’s dedication to innovation and what people like.
Hutchinson Bottles (1890s-1900s)
The Hutchinson bottle was the first for Coca-Cola, used from the mid-1890s to early 1900s. It had a special stopper design. Today, these bottles are very valuable to antique coke bottle valuation collectors because they’re rare and historic.
Straight-Sided Bottles (1900-1920)
The straight-sided bottle was used from 1900 to 1920. It came in different sizes, colors, and markings. These bottles helped Coca-Cola grow, as the brand spread across the United States.
Contour “Hobbleskirt” Bottles (1916-Present)
The contour “hobbleskirt” bottle, introduced in 1916, is now the symbol of Coca-Cola. Its unique shape was trademarked in 1961. The bottle has changed over time, with new materials like aluminum and plant-based plastics. This shows Coca-Cola’s focus on innovation and being green.
“The form of the Coca‑Cola bottle has evolved over the years, including updates such as the aluminum bottle introduced in the 21st century.”
Coca-Cola’s packaging changes show the brand’s ability to keep up with new trends and tech. Yet, it still holds onto the classic contour bottle’s charm.
How to Date a Coke Bottle by Design Features
Figuring out a Coke bottle’s age and where it was made isn’t just about looking for dates or codes. The bottle’s design holds clues to its past. From the glass shape and color to the manufacturing marks and seams, each detail tells a story.
Bottle Shape Identification
The Coke bottle has changed over the years, with three main styles. The Hutchinson bottle, popular in the late 1800s and early 1900s, has high shoulders and straight sides. Then, there’s the straight-sided bottle, used from 1900 to 1920, with a simple shape.
The contour or “hobbleskirt” bottle, introduced in 1916, is the most recognizable. It has a distinctive pinched waist.
Glass Color Variations
Coke bottles have been made in many glass colors, from clear to amber and green. Amber bottles were more common in the South and Midwest. Green glass was used in other areas.
These color differences can help date a bottle. Certain colors were used during specific times or in certain places.
Manufacturing Marks and Seams
The way Coke bottles were made left marks that help date them. Early bottles with an applied top show stretch marks and seam lines that don’t reach the lip. Machine-made bottles have seam lines that go all the way to the top.
Contour bottles might have small date marks on the waist or heel. These marks can tell you exactly when they were made.
| Bottle Feature | Clues to Age |
|---|---|
| Bottle Shape | Hutchinson (1890s-1900s), Straight-Sided (1900-1920), Contour “Hobbleskirt” (1916-Present) |
| Glass Color | Clear, Amber (South/Midwest), Green |
| Manufacturing Marks | Applied Top Seams, Machine-Made Seams, Date Codes |
By looking closely at a Coke bottle’s design, collectors can learn a lot. They can find out when it was made, where, and its place in the brand’s history.
Patent Markings and Production Dates
Figuring out the age of Coca-Cola bottles often involves looking at patent markings and production dates. These details help us understand how old and real your vintage Coca-Cola bottle collection is.
“U.S. Pat. Office, 6-1/2 oz.” is a common marking on Coke bottles. It means the bottle was made between 1958 and 1965. Older bottles might say “U.S. Pat. Office, 6 oz.” (1951-1958) or “Pat. D-105529” (1938-1951).
Bottles with “Pat’d Dec. 25, 1923” were made from 1928 to 1938. Those with “Pat’d Nov. 16, 1915” were produced from 1916 to 1928.
Date codes on the bottle’s waist or heel can also tell us when it was made. For example, “42 L 87” means it was made in 1942. But, bottles from 1938 and before might not have these markings.
“Identifying the patent markings and production dates on vintage Coca-Cola bottles can be a fascinating window into the brand’s rich history.”
Knowing how to read these patent and date codes is key for identifying old Coke bottles and authenticating vintage Coca-Cola bottle collections. By looking closely at these details, collectors can learn the history behind each bottle.
Decoding Bottle Base Markings
Looking at the base of a Coca-Cola bottle can tell you a lot. For years, the company marked the bottoms with city names and codes. This helps collectors figure out when and where the bottle was made.
City Names and Manufacturer Codes
Until the early 1960s, bottles showed the city of production on the base. This helps narrow down where the bottle came from. Companies also used special codes like “CHATT” for Chattanooga Glass and “LGW” for Laurens Glass Works.
Date Code Systems
Figuring out the date codes on Coke bottles can be tricky. Early bottles (1916-1938) had two-digit year codes on the heel. From 1938 to 1965, codes were on the waist. After 1960, the codes changed again, making it harder to tell when they were made.
| Bottle Type | Date Code Location | Date Code Format |
|---|---|---|
| Early Contour (1916-1938) | Heel | Two-digit year |
| Mid-Century (1938-1965) | Waist | Varies |
