INFUSION PACKAGES

摘要

An infusion package (1) has two panels (2, 3), each of which has been formed to a hemispherical shape. The panels are sealed together around their peripheral margins (4) to form an infusion containing chamber that contains an infusible substance, such as tea or coffee. When the package (1) is immersed in hot liquid (e.g. by pouring water at 850C to 1000C onto it) it will tend to re-adopt its formed shape and thus an expanded, three-dimensional, volume.
