A cartridge (10) for forming a beverage includes a container (12) defining an interior space (14), a filter (30), a beverage medium (20) contained in the interior space, an a filter guard (40). The filter (30) may be arranged so that liquid that interacts with the beverage medium flows through the filter to exit the interior space. The container may include a surface arranged to be pierced by a piercing member (52) to permit beverage to exit the container. The filter guard (40) may be arranged to contact the piercing member (52) to resist damage to the filter when the container surface is pierced. In one embodiment, the filter guard (40) and filter (30) may be in contact with the container surface that is pierced, yet damage to the filter that might be caused by the piercing element may be avoided. |
