1. A head assembly for a brewing apparatus, comprising: (a) a movable lid portion having a top surface, a bottom surface and an opening therethrough;(b) a fixed base portion having a brewing cartridge opening and a top surface, a bottom surface and an opening therethrough, the moveable lid portion being rotatable between an open position for receiving the brewing cartridge, and a closed position for sealing the brewing cartridge between the fixed base portion and the moveable lid portion;(c) a slideable lock having a first end coupled to the top surface of the moveable lid portion and having a second end of the slideable lock terminating in a hook and extending through the opening in the moveable lid portion and the opening in the fixed base portion to provide a locked position for engaging the bottom surface of the fixed base portion when the moveable lid portion is in the closed position, and an unlocked position for releasing the bottom surface of the base portion;(d) an axis point connected to the moveable lid portion, for moving the slideable lock between the locked and unlocked positions; and(e) a cover or a handle movably coupled to the first portion of the slideable lock such that pressure on the cover or handle rotates the moveable lid portion to the closed position, and slides the lock into the locked position. 2. The brewing apparatus of claim 1 wherein the moveable lid portion further comprises a lever, a base plate and a support tower extending upwards from the base plate, the support tower rotatably supporting the lever at a second axis point. 3. The brewing apparatus of claim 2 wherein one end of the lever has a bearing surface for facilitating motion of the second end against the cover. 4. The brewing apparatus of claim 3 wherein the bearing surface is provided by a roller bearing. 5. The brewing apparatus of claim 1 wherein the moveable lid portion is biased towards the open position. 6. The brewing apparatus of claim 1 wherein the slideable lock is biased towards the unlocked position. 7. The brewing apparatus of claim 1, further comprising an injection pin connected to the lid portion for piercing the brewing cartridge in the closed position. 8. The brewing apparatus of claim 1, further comprising: a cartridge holder rotatably mounted within the fixed base portion and having a resting position for receiving the brewing cartridge, and an ejection position for ejecting a spent brewing cartridge. 9. The brewing apparatus of claim 8, further comprising: an arm having a first end fixed to the moveable lid portion and a second end configured to contact the cartridge holder;wherein movement of the movable lid portion from the closed position to the open position causes movement of the arm for contacting the cartridge holder and rotating the cartridge holder to the ejection position. 10. The brewing apparatus of claim 9 wherein the arm is configured to contact a dog rotatably connected to the cartridge holder, and wherein the dog is configured to resist rotation in a first direction for causing the cartridge holder to rotate, and then to rotate in an opposite second direction. 11. The brewing apparatus of claim 1, further comprising: a shuttle supporting an extraction pin and slideably mounted within the fixed base portion, the shuttle having a resting position and a brewing position for piercing a cartridge with the extraction pin;wherein the hook is configured to engage the shuttle for sliding the shuttle to a brewing position. 12. The brewing apparatus of claim 11 wherein the extraction pin has a bend therein. 13. A head assembly for a brewing apparatus, comprising: (a) a fixed base portion;(b) a movable lid portion having a top surface, a bottom surface and an opening therethrough, the moveable lid portion coupled to the fixed base portion, the moveable lid portion being rotatable between an open position for receiving a brewing cartridge, and a closed position for sealing the cartridge between the moveable lid portion and the fixed based portion;(c) a lock having a first end slideably coupled to the top surface of the moveable lid portion and a second end of the lock extending through the opening in the moveable lid portion to provide a locked position for engaging the fixed base portion when the lid portion is in the closed position, and an unlocked position for releasing the base portion;(d) an articulated arm having a first end connected to the first end of the lock, an opposing second end of the articulated arm connected to the moveable lid portion, and a hinge between the first end and the second end, the articulated arm being configured to articulate about the hinge between a bent position for placing the lock in the unlocked position, and a straightened position for placing the lock in the locked position; and(e) a cover movably coupled to the moveable lid portion and configured for abutting the articulated arm adjacent to the hinge when the moveable lid portion is in the closed position, such that pressure on the cover rotates the moveable lid portion to the closed position, and subsequently displaces the articulated arm to the straightened position. 14. The head assembly of claim 13, comprising a second articulated arm having a first end connected to the lock, an opposing second end connected to the moveable lid portion, and a hinge between the first end and the second end. 15. The head assembly of claim 13, the cover having an internal ledge configured to contact the articulated arm adjacent to the hinge. 16. The head assembly of claim 13, further comprising a spring having a first end connected to the moveable lid portion and a second end connected to an inside wall of the cover, wherein the spring is compressed when the moveable lid portion is in the closed position and the lock is in the locked position. 17. A head assembly for a brewing apparatus, comprising: (a) a fixed base portion;(b) a movable lid portion having a top surface, a bottom surface and an opening therethrough coupled to the fixed base portion, the moveable lid portion being rotatable between an open position for receiving a brewing cartridge, and a closed position for sealing the cartridge between the moveable lid portion and the fixed base portion;(c) a lock having a first end slideably coupled to the top surface of the moveable lid portion and a second end of the lock extending through the opening in the moveable lid portion to provide a locked position for engaging the fixed base portion when the moveable lid portion is in the closed position, and an unlocked position for releasing the fixed base portion; the lock having a toothed rack disposed on the first end thereof;(d) a cover or handle movably coupled to the first end of the lock with a pinion gear configured to engage the toothed rack, such that rotation of the cover or handle relative to the fixed base portion rotates the pinion gear and slides the lock to the locked position or the unlocked position on the fixed base portion. 18. The head assembly of claim 17, further comprising: a track affixed to an interior surface of the cover and defining a channel;a bolt slideable within the channel between a raised position and a lowered position, and having a pin extending into a slot defined within the pinion gear;the slot including a pit, for receiving the pin when the bolt is in the lowered position and preventing rotation of the pinion gear and handle. 19. The head assembly of claim 1 wherein the slideable lock is locked and unlocked by a tower and cover combination, a lever and cover combination or a handle and rack and pinion combination. 20. The brewing apparatus of claim 19 wherein the first end of the slidable lock is a planar member and the hook of the lock includes a pair of hooks depending from opposing sides of the planar member, the planar member being slidably coupled to the moveable lid portion.
