Cultural Tip
In most Spanish‑speaking countries ‘tupper’ (or ‘tupperware’) is the everyday word for any reusable plastic food container, regardless of brand. The adjective ‘hermético’ is often used to stress that the lid closes tightly, a feature prized for keeping food fresh and for avoiding spills when transporting meals. When speaking formally you might prefer ‘recipiente’ or ‘envase’, but in casual conversation ‘tupper’ is perfectly natural.
