Abstract: A capsule for use in preparing a beverage in a beverage preparation device that has a brewing chamber. The capsule has a body having a cup shape that defines an internal cavity within which to contain a beverage ingredient, and a flange that extends radially outwardly from a mouth of the body. The flange includes a chamber engagement portion that, during preparation of a beverage, is to be in engagement with components of the beverage preparation device that define the brewing chamber. The body and the flange are formed of compressed pulp fibre material. The chamber engagement portion of the flange has a density of the pulp fibre material that is less than the maximum density of the pulp fibre material in the body.

Abstract: A packaging material is provided including a substrate, and an oxygen transmission inhibiting layer that is carried by the substrate. The oxygen transmission inhibiting layer is formed of a composite material including a linear polysaccharide medium within which one or more additives are dispersed. The composite material is capable of forming a substantially continuous film to provide a barrier to transmission of oxygen gas. The oxygen transmission inhibiting layer is configured within the packaging material at a thickness that is efficacious in inhibiting the transmission of oxygen gas therethrough. A packaging device has two or more component parts, at least one of which is formed of the packaging material. The component parts of the packaging device are shaped and/or configured to be assembled to define an interior region within which goods are to be contained.
