## Abstract

A milk beverage feeding device includes an undiluted-solution storage storing a milk-beverage undiluted solution; an undiluted-solution feeder feeding the milk-beverage undiluted solution; a vapor feeder feeding a pressurized vapor in a pressurized state; an air feeder feeding compressed air in a compressed state; and a mixer mixing the milk-beverage undiluted solution fed from the undiluted-solution storage through the undiluted-solution feeder, the pressurized vapor fed from the vapor feeder, and the compressed air fed from the air feeder to form a mixture and feed the mixture as a milk beverage to a beverage container.

## Claims

### Claim 1

A milk beverage feeding device comprising
an undiluted-solution storage configured to store a milk-beverage undiluted solution;
an undiluted-solution feeder configured to feed the milk-beverage undiluted solution;
a vapor feeder configured to feed a pressurized vapor in a pressurized state;
an air feeder configured to feed compressed air in a compressed state;
a mixer configured to mix the milk-beverage undiluted solution fed from the undiluted-solution storage through the undiluted-solution feeder, the pressurized vapor fed from the vapor feeder, and the compressed air fed from the air feeder to form a mixture and feed the mixture as a milk beverage; and
a foamer device including a passage to transfer the milk beverage, the passage having an intersection point connecting an axis of an upstream side of the passage to an axis of a downstream side of the passage at an acute angle to cause the milk beverage to hit a wall surface of the passage when the milk beverage transferred through the passage to increase the foaming quality of the milk beverage.

### Claim 2 (depends on 1)

The milk beverage feeding device according to claim 1, wherein the undiluted solution storage is a bag-in-box which is a box-like container accommodating a bag-like container enclosing a milk-beverage undiluted solution.

### Claim 3

A milk beverage feeding device comprising:
an undiluted-solution storage configured to store a milk-beverage undiluted solution;
an undiluted-solution feeder configured to feed the milk-beverage undiluted solution;
a vapor feeder configured to feed a pressurized vapor in a pressurized state;
an air feeder configured to feed compressed air in a compressed state; and
a mixer configured to mix the milk-beverage undiluted solution fed from the undiluted-solution storage through the undiluted-solution feeder, the pressurized vapor fed from the vapor feeder, and the compressed air fed from the air feeder to form a mixture and feed the mixture as a milk beverage to a beverage container, the mixer including
a channel extending in a vertical direction, and
a check valve provided in the channel to allow a fluid to pass therethrough upward from below but restrict the fluid to pass therethrough downward from above, wherein
the pressurized vapor and the compressed air having passed through the check valve are mixed with the milk-beverage undiluted solution fed through the undiluted-solution feeder on an upper side of the check valve in the channel.
