Natural Language Definition
EN
An enclosure is a material artifact that bears the function of surrounding and separating objects or substances within its closed boundary from the external environment, providing containment, protection, or isolation.
PT-BR
Um invólucro é um artefato material que tem a função de envolver e separar objetos ou substâncias dentro de seu limite fechado do ambiente externo, proporcionando contenção, proteção ou isolamento.

spatial containment — the enclosure maintains a separation between interior and exterior regions without a directed material flow
An enclosure is characterised by its structural boundary function rather than by a process it transforms; its process participation is in protection, containment, and isolation processes.
