Thermos Powered Jeep Production

• CATEGORIES: Advertising & Brochures, Features

This ad by the American Thermos Bottle Company was published in the May 22, 1943, issue of the Saturday Evening Post. I believe the takeaway from this ad is, If Thermos products are good enough for workers building jeeps, than they are good enough for the average American. However, there seems to be a lack of evidence that Willys and Ford employees were using Thermos products.

    A lot of people in manufacturing jobs use to carry lunch pails including kids in school. These were made to carry Thermos Bottles. The Thermos Bottle contents could be coffee, soup, milk, etc. In the 1940’s people understood this.

    I probably should have rephrased my introduction as a question. I knew vacuum bottles were very common at the time (and were common for me when I was a kid going to school in the 1970s — mom would put soups in my “thermos” for lunch, which was synonymous with vacuum bottle for me). Were there other vacuum bottle makers apart from Thermos or if you had a vacuum bottle, it was almost certain it was a Thermos? … I may have to google this later.

    My dad carried one just like this for years in his lunch bucket. After he wore that one out, he got a much larger thermos and made a handle for it and used that for years as well. You could buy replacement liners for them also.

    Interesting enough, Thermos attempted to make “vacuum flask” and Thermos synonymous in the early 20th century, but then realized the company might lose it’s Trademark, so reversed course. But, its reverse attempt eventually failed when a judge eventually ruled that “thermos” had become a generic term for the vacuum flask (though Thermos with a cap “T” did remain a Thermos trademark).


    thermos bottles – – we were too poor to afford one — so us mountain kids just did without — in fact one family was so poor they ate blue jays — true story

    I don’t know if Blue Jays taste like chicken, but I have had occasion during the course of my career to eat crow a few times. Not tasty, and the end result is not being able to sit down without pain. LOL!!!!!!
