Openable

Openable is an adjective used to describe objects that are designed to be opened. An item is openable when it incorporates a mechanism—such as a lid, hinge, cap, door, or flap—that provides access to its interior or contents. The term is commonly applied in product design, packaging, architecture, and logistics, and may imply a balance between ease of access and security, durability, or containment.

In packaging, openable containers use resealable closures, seals, grips, and sometimes tamper-evident features to allow repeated access while protecting contents. In furniture and building design, openable elements like doors, windows, drawers, and panels facilitate use, ventilation, and maintenance, and may include ergonomic or accessibility considerations.

In computing and digital contexts, the concept of openable is extended to resources (files, documents, dialogs) and user interfaces that can be opened by an action. Although openable is primarily used for physical items, it appears in documentation and specifications to denote items that expose interior content or options when engaged.
