    Abstract: A package (10) of an infusible substance, typically tea or coffee, is disclosed. This package (10) preferably comprises a tubular structure (17) of a liquid permeable material which contains the infusible substance. The structure has a lower portion (11) and an upper portion (12) and is sealed at a lower end (13) and an upper end (14) in a manner such that when the lower portion (11) is immersed in a liquid, the infusible substance is retained substantially within the structure (17) whilst the liquid permeates the infusible substance and the upper portion (12) projects out of the liquid to facilitate gripping thereof. In this way, the package (10) containing tea leaves, may be immersed, for example, in a cup of hot water to produce tea.
