pillbox

Pillbox is a term that can refer to several box-shaped objects or concepts. The most common senses are a small, lidded container for pills, a compact military fortification, and a type of hat named for its boxy shape. The unifying idea is the compact, box-like form.

Pillbox as a container describes a compact case used to carry or store medications. These containers are typically made of plastic or metal and may be cylindrical or rectangular. They often include a snap or screw-on lid and, in many jurisdictions, child-resistant closures. Pillboxes may be simple single-compartment boxes or feature multiple compartments to organize various pills or vitamins, making them convenient for travel or daily use.

Pillbox as a defensive fortification refers to a small, single-purpose outpost or gun post used in the 20th century. Usually constructed of concrete or earth, these structures are low-profile with narrow openings (embrasures) for rifles or small artillery. Pillboxes are designed to provide protected firing positions while remaining difficult to detect and resistant to small arms fire. They were common in coastal, border, and field defenses and are often found in fortified lines from various conflicts, including World War I and World War II.

Pillbox hat is a fashion item popular in the mid-20th century, particularly the 1950s. It is a small, brimless hat with a short crown that sits close to the head, often made from felt, wool, or straw and sometimes adorned with decorative accents. The hat’s box-like silhouette gave rise to its name and contributed to a distinctive, formal look associated with that era.

In everyday language, “pillbox” thus denotes both a practical container and two distinct uses—military architecture and a vintage hat—sharing a common compact, boxy form.
