Introduction
Vacuum bottles, commonly known as thermos flasks, are ubiquitous in modern life. They serve the simple yet essential function of maintaining the temperature of their contents, whether hot or cold. Despite their straightforward purpose, vacuum bottles have been integrated into various cultures in unique and interesting ways. This blog post explores the role of vacuum bottles across different cultures, highlighting their history, significance, and diverse applications.
1. The Origin and Evolution of Vacuum Bottles
