Abstract: A heating attachment for improving uniformity of microwave heating of a food product in a food container. The heating attachment has a microwave shield of microwave-reflective material. An attachment member is configured for attaching the shield to a food container in an operative association in which the container is disposed in a heating space by the shield. In this association, the shield improves the uniformity of microwave heating of a food product within the container. The heating attachment sufficiently surrounds the container in the operative association to capture the container for promoting breakage of the heating attachment when the container is removed therefrom to inhibit or prevent reuse of the heating attachment.

Abstract: The invention relates to a capsule for the preparation of a beverage obtained by supplying hot water within the capsule under pressure and releasing the beverage from the capsule. The capsule includes a food substance therein, a first surface adapted to be traversed by a flow of water entering the capsule, and a second surface adapted to be traversed by a flow of beverage exiting the capsule. The second surface is adapted to deform outwardly upon action of the inside water pressure thereon. Also, that surface includes at least one opening member capable of deforming inwards the capsule upon a mechanical reaction force applied from outside onto the closure member as a result of the deformation of the second surface due to the build-up of the inside pressure.
