Rapidly cooling food and drinks

1. A pod for providing a single serving of a cooled food or drink, the pod comprising:

a substantially rigid container having a first end and a sidewall, the first end and the sidewall together defining an interior, a portion of the first end configured to be opened by an application of a force;

a mixing paddle movably disposed within the interior of the substantially rigid container; the mixing paddle operable to stir at least one ingredient;

a drive head coupled to the mixing paddle such that rotation of the drive head causes rotation of the mixing paddle, the drive head comprising exterior threads on a cylindrical outer surface and defining a receptacle for engaging with a driveshaft of a machine to couple rotation of the driveshaft and the drive head; and

a seal member fixed to a second end of the substantially rigid container, the seal member comprising an internal thread engaged with the exterior threads of the drive head such that a rotation of the drive head in a first direction relative to the seal member fixed in position causes an axial translation of the drive head relative to the seal member and into the interior.

2. The pod of claim 1 , wherein the drive head is axially moveable between an engaged position in which the internal thread of the seal member and the external threads of the drive head are engaged and a disengaged position in which further rotation of the drive head in the first direction rotates the drive head without further translating the drive head into the interior.

3. The pod of claim 2 , wherein the drive head and the seal member are configured such that rotation of the drive head in a second direction opposite the first direction causes an axial translation of the drive head away from the interior.

4. The pod of claim 1 , wherein the drive head comprises a sealing element that limits fluid flow between the drive head and the seal member when the drive head is in its engaged position.

5. The pod of claim 4 , wherein the sealing element comprises an o-ring.

6. The pod of claim 4 , wherein the sealing element of the drive head is spaced apart from the seal member when the drive head is in its disengaged position.

7. The pod of claim 6 , wherein air is allowed to enter to the pod once a substantial seal is broken and the air is used to aid in stirring of the cooled food or drink and a production of overrun.

8. The pod of claim 1 , wherein the at least one ingredient for forming the single serving of the cooled food or drink is disposed within the interior of the substantially rigid container.

9. The pod of claim 1 , wherein the drive head is rotationally coupled to the mixing paddle by a permanent connection.

10. The pod of claim 9 , wherein the drive head is molded to the mixing paddle.

11. The pod of claim 1 , wherein the drive head is rotationally coupled to the mixing paddle by a friction connection that is formed by engaging one or more grooves of the drive head onto complementary one or more edges of the mixing paddle.

12. The pod of claim 1 , wherein the drive head comprises a cylindrical section that is configured to center the drive head and the mixing paddle in the pod when the threaded connection is disengaged.

13. The pod of claim 1 , wherein the mixing paddle contacts a lip of the substantially rigid container when the drive head is in its disengaged position.

14. The pod of claim 1 , wherein the mixing paddle comprises bent portions mated to the drive head for providing the rotational coupling between to the drive head and the mixing paddle.
