Welcome to Anatomy 101. Today, we will take a brief look at all the parts and pieces that make up our beloved thermos bottles. These lessons are intended to get you acquainted with the many names and purposes of each part.
In 1892, the first successful vacuum bottle was created in a laboratory by James Dewar, an English scientist. Since then, millions and millions of bottles have been produced. But what parts actually make up these bottles? For our demonstration, we will be focusing mainly on the traditional steel/glass vacuum bottle of the 1950s and 1960s. Let us begin!
Lesson One: The Sleeve
The steel tube into which the glass filler is inserted to form the traditional vacuum bottle (thermos). The sleeve consists of the litho, top and bottom rims, and the base (bottom). For character kits, the sleeve is usually lithographed with the same theme as the lunch box.

Lesson Two: The Stopper
The cork, rubber, or plastic piece that prevents the contents of the bottle from spilling out, as well as keeping hot or cold by means of sealing in the air.
|
Lesson Three: The Collar
The plastic or metal piece that threads onto the top (open end) of the sleeve and conceals the glass filler. The collar basically "holds" the bottle together, as the sleeve, stopper, and cup all connect at the collar.
|
Lesson Four: The Cup
The plastic drinking cup which fits on top of the thermos bottle. The cup is securely held in place by screwing onto the collar.
|
Lesson Five: The Glass Filler
The breakable glass insert of a traditional vacuum bottle. Injection molded plastic bottles brought glass fillers to extinction.
|
Lesson Six: The Gasket
The gasket is positioned at the inside top of the collar. When the collar fits onto the sleeve, the gasket forms a seal between the glass filler and collar, thus preventing any liquids from spilling inside the sleeve.
|
Lesson Seven: The Shock Absorber
The shock absorber is located at the inside bottom (base) of the sleeve. The shock absorber cushions the glass filler, keeping the glass from breaking during normal use.
