wherein the piercing member is configured to pierce the first frangible region of the body, and wherein the piercing member is configured to pierce the second frangible region of the lid.
2. The capsule according to claim 1 , wherein the piercing member is elongate and the opposing ends are configured to pierce the lid and the body respectively.
3. The capsule according to claim 1 , wherein the piercing member, in cross section, defines regions of relatively larger and reduced radial extent.
4. The capsule according to claim 1 , wherein the piercing member comprises a central elongate core, and a plurality of ribs extending therefrom along at least part of the length of the central elongate core.
5. The capsule according to claim 4 , wherein the ribs extend substantially radially away from the central elongate core.
6. The capsule according to claim 1 , wherein the piercing member has a substantially x-shaped cross section.
7. The capsule according to claim 1 , wherein the piercing member comprises a plurality of locating braces, and wherein at least some of the locating braces extend laterally from the elongate direction of the piercing member, and retain the piercing member in position inside the capsule with the opposing ends adjacent the first and the second frangible regions of the capsule.
8. The capsule according to claim 1 , wherein an end of the piercing member comprises one or more flanges for enlarging a hole formed by the piercing member on piercing of the frangible region of the capsule.
9. The capsule according to claim 1 , wherein the piercing member is formed as a separate part, and is not attached to the remainder of the capsule.
10. A dispensing apparatus comprising:
a mount for receiving the capsule according to claim 1 , containing the flavoring to be added to the beverage; and
an engaging portion configured to engage with the piercing member positioned within the capsule and pierce the first and/or the second frangible region of the capsule,
wherein the dispensing apparatus is configured to provide relative movement of the mount and the engaging portion between a retracted position and an engaged position in which the engaging portion is configured to engage with the piercing member in the capsule.
11. The dispensing apparatus according to claim 10 , the dispensing apparatus being configured to be retrofittable to an existing beverage dispensing unit.
12. The dispensing apparatus as claimed in claim 10 , wherein the engaging portion is a beverage dispensing nozzle.
13. The dispensing apparatus as claimed in claim 10 , wherein the engaging portion is movable relative to the dispensing apparatus.
14. The dispensing apparatus as claimed in claim 10 , wherein the dispensing apparatus comprises a tap operable to both open a valve and move the engaging portion to engage with the piercing member in the capsule mounted in the mount.
15. The dispensing apparatus as claimed in claim 10 , wherein the mount is removable from the dispensing apparatus.
16. The dispensing apparatus as claimed in claim 10 , wherein the mount comprises a through hole, which is restricted at one end to retain the capsule within the through hole, while allowing beverage to flow there through.
