Support is provided so that the feeding bottle B is rotatably supported in a state of being formed at an angle with respect to the horizontal. Thereby, the nipple portion of the breast bottle B can be prevented from coming into contact with the cooling medium in the cooling tank 2.

Here, the nipple portion of the nursing bottle B is provided for the baby to be contained in the mouth, and therefore it is extremely important for hygiene to prevent contact with the cooling medium when it is used in a public place such as a commercial establishment.

In this regard, for example, in the case of a canned beverage such as beer, since the person who drinks the beverage is not an infant, even if the canned beverage is immersed in cold water for cooling, the whole is not in the water and there is no special. problem.

In view of the cooling efficiency, in order to increase the contact area between the cold water and the tank surface as much as possible, it is desirable to traverse the filling beverage so that its longitudinal axis is horizontal, so that the entire tank is not in the water as much as possible.

On the other hand, in the case of the feeding bottle B, the nipple portion cannot be made to be in the water for hygienic reasons, so that the cooling in the horizontal state (the horizontal state) cannot be performed, which is unique to the feeding bottle B. Happening. The present invention is also completed in consideration of the conditions unique to the feeding bottle.

Next, the operation of the feeding bottle cooling device 1 of the present embodiment will be described.

In the state shown in Figs. 1 and 2, when the driving source 8 including the motor is started and the pair of side roller members 5A are rotationally driven, the feeding bottle B is rotated about its longitudinal axis.

Here, the side roller member 5D disposed on the inner side of the lid member 10 elastically presses the side peripheral surface of the feeding bottle B from above, so that the vibration of the feeding bottle B is suppressed and the rotation operation is stabilized, and the rotation operation can be stabilized. It is sure to prevent the bulging of the feeding bottle B when rotating.

Further, when the feeding bottle B is rotated inside the cooling medium (cold water), the milk contained in the inside of the feeding bottle B is stirred, so that the cooling efficiency is improved, and the milk can be quickly cooled.

Specifically, milk of a high temperature of about 70 ° C can be cooled to 50 ° C or less in a short time (less than 5 minutes (preferably 1 minute, 2 minutes)). Further, the temperature of the milk inside the feeding bottle B is made uniform by the stirring effect caused by the rotation.

The cooling efficiency (heat transfer rate) and the amount of heat to be cooled vary depending on the material of the feeding bottle B or the milk capacity. Therefore, the control unit 14 can set an appropriate cooling time in accordance with the material or the capacity.

Specifically, the cooling efficiency of the glass bottle N is higher than that of the resin bottle B made of a polypropylene (PP), so that a relatively short cooling time is set in the case of cooling the glass bottle B. On the other hand, a relatively long cooling time is set in the case of cooling the feeding bottle B made of polypropylene.

Further, the setting of the cooling time and the rotation speed can be performed not only according to the material of the feeding bottle B but also by the capacity of the feeding bottle B. That is, in the case of the long-sized large-capacity feeding bottle B1, the cooling time is extended, or the rotation speed is increased. On the other hand, in the case of the short-sized small-capacity feeding bottle B2, the cooling time is reversed or the rotation speed is delayed.

As shown in FIG. 1 and FIG. 2, the temperature sensor 16 for detecting the temperature of the cooling medium during cooling or the temperature of the milk inside the feeding bottle B may be set, thereby performing the temperature according to the temperature detected by the temperature sensor 16. Automatic control. As the temperature sensor 16, a non-contact temperature sensor 16 can also be used.

As shown in Fig. 19, the operation panel 17 (provided on the main body casing 3) of the bottle-cooling device 1 of the present embodiment includes when the material of the breast bottle B is glass and when it is polypropylene (PP). The changeover switch 18 is switched to select whether the breastfeeding bottle B is a long-sized (large-capacity) or a short-sized (small-capacity) push switch 19, 20, and a start button 21 that starts the cooling by rotating the breastfeed bottle B.

Furthermore, a dial type mechanism can also be used in the operation panel 17.

Further, according to the capacity and material of the feeding bottle B, the switching switch 18 and the pressing switches 19 and 20 on the operation panel 17 are appropriately operated, thereby selecting an appropriate speed (rotation speed) corresponding to the capacity and material of the feeding bottle B. ) and cooling time (rotation time). Thereby, overcooling or insufficient cooling can be prevented, so that the milk in the feeding bottle B can be adjusted to a suitable temperature.

Further, as a modification of the above embodiment, as shown in FIG. 20, the cover member 10A may be attached to the main body casing 3 so as to be openable and closable by a hinge structure.

According to the feeding bottle cooling device 1 of the present embodiment, the milk adjusted to a temperature higher than a suitable temperature (for example, 70 ° C) can be quickly cooled to a suitable temperature without relying on a human hand. .

Therefore, the operator can use the time previously spent to cool the milk, for example, The cleaning of the utensils used in the milk adjustment, etc., thereby reducing the operational burden.

Further, according to the breast bottle cooling device 1 of the present embodiment, it is not necessary to cool the tap water from the faucet as it was previously cooled by a human hand, and thus the water saving effect can be expected.

Incidentally, in the lounge of a commercial establishment (department store, etc.), after all, it is sometimes impossible to use the tap of the tap water (the tap water flows out from the tap). In this regard, the bottle-cooling device 1 of the present embodiment can ensure the amount of cold water equivalent to the amount of cold water poured into the cooling tank 2 (it can also be water obtained by mixing ice cubes in water at normal temperature). The cooling of the feeding bottle B can be performed, so that the restriction on the place when the cooling of the feeding bottle B is performed can be greatly alleviated.

Further, the operation panel 17 and the control unit 14 can set an appropriate cooling rate (rotation speed) and a cooling time (rotation time) according to the capacity or material of the feeding bottle B, thereby preventing overcooling or insufficient cooling of the milk.

Further, in the above-described embodiment, the configuration in which the feeding bottle B is rotated by the driving source 8 such as a motor has been described as an example. In the feeding bottle cooling device of the present invention, the feeding bottle B can be rotated by hand. .

Further, in the above embodiment, the configuration of the discharge device 15 for discharging the cooling medium from the cooling tank 2 has been described as an example. However, in the bottle-cooling device of the present invention, the discharge device is not an essential component.
