Abstract

The invention provides a mixing apparatus. The mixing apparatus includes a first container, wherein the first container comprises: a first port; and a mixing chamber. The mixing apparatus further includes a second container, wherein the second container is adapted to receive the first container, and a seal disposed between the first container and the second container. In addition, the mixing apparatus includes a channel between the first port and the mixing chamber, wherein the channel is defined by the seal and the first container. In some examples, the seal includes: a first seal portion; and a transition seal portion, the transition portion comprising: a seal split; and an air intake channel.

First claim

1 . A mixing apparatus comprising:
a first container, wherein the first container comprises:
a first port; and
a mixing chamber for mixing milk with steam and/or air;
a second container, wherein the second container is adapted to receive the first container; a seal disposed between the first container and the second container; and a channel between the first port and the mixing chamber, wherein the channel is defined by the seal and the first or second container.

2 . The mixing apparatus of claim 1 , wherein the first container comprises a raised container portion, and wherein the channel is further defined by the raised container portion.

3 . The mixing apparatus of claim 2 , wherein the raised container portion causes an indentation in the seal of greater than 0.2 mm.

4 . The mixing apparatus of claim 1 , wherein the seal comprises a raised seal portion, and wherein the channel is further defined by the raised seal portion.

5 . The mixing apparatus of claim 1 , wherein the second container comprises:
a second port; and a third port, wherein the third port in assembled condition is connected to the mixing chamber, and wherein the channel further connects the second port to the first port and the mixing chamber.

6 . The mixing apparatus of claim 1 , wherein the seal comprises:
a first sealing portion; a second sealing portion comprising a first seal port; and a third sealing portion.

7 . The mixing apparatus of claim 6 , wherein at least one of a: seal thickness seal width, and shore hardness of the first, second, or third sealing portions are different to a corresponding parameter of an other sealing portion of the first, second, or third sealing portions.

8 . The mixing apparatus of claim 6 , wherein the channel comprises:
a first channel portion, wherein the first channel portion is defined by the first sealing portion and the first container, and wherein the first channel portion is connected to the first port; a second channel portion connected to the first channel portion, wherein the second channel portion is defined by the second sealing portion and the first container; and a third channel portion connected to the first and second channel portions and the mixing chamber wherein the third channel portion is defined by the third sealing portion and the first container.

9 . The mixing apparatus of claim 8 , wherein the first channel portion is adapted to receive milk by way of the first port.

10 . The mixing apparatus of claim 8 , wherein the second channel portion is adapted to receive steam by way of the first seal port.

11 . The mixing apparatus of claim 8 , wherein the third channel portion is adapted to receive input from the first and second channel portions, and wherein the third channel portion is adapted to impart a Venturi effect on the received input.

12 . The mixing apparatus of claim 6 , wherein the seal comprises a span seal.

13 . The mixing apparatus of claim 12 , wherein a span width of the first, second and third sealing portions are different to each other.

14 . The mixing apparatus of claim 1 , wherein a shore hardness of the seal is in the range of 30 to 60 shore.

15 . A coffee maker, the coffee maker comprising;
a liquid coffee extraction apparatus; and the mixing apparatus of claim 1 .

16 . The mixing apparatus of claim 2 , wherein the raised container portion causes an indentation in the seal of greater than 0.5 mm.

17 . A mixing apparatus comprising:
a container, wherein the first container comprises:
a port; and
a mixing chamber for mixing milk with steam and/or air;
a seal; and a channel between the port and the mixing chamber, wherein the channel is defined by the seal and the container.
