Cap
A cap is a fitted covering for the head, often with a brim or visor, commonly worn for protection, style, or as a symbol of affiliation in sports or professions. In a broader context, it means to impose an upper limit on something, like costs or quantities, which has become a key tool in modern policy-making to manage resources and prevent overreach.

The invention of the modern bottle cap in 1892 by American inventor William Painter not only stemmed from the word 'cap' but also transformed the beverage industry by enabling sealed bottles, preventing spoilage for millions. Today, this simple design is used on over 300 billion bottles annually, indirectly influencing global recycling efforts as plastic caps make up a significant portion of ocean plastic waste.
