Description

  The present invention relates to a container-equipped beverage cooling apparatus that cools and provides beverages contained in containers such as PET bottles, bottle cans, and glass bottles.

  In recent years, with the spread of PET bottles and the like, many people carry bottle containers containing beverages such as tea and sports drinks. The bottle container has a screw-type cap at the mouth, and after the required amount of beverage has been drunk, the cap can be closed again to save the rest and drink it later. If such a beverage is a beverage for cooling, it is required to keep the beverage in a cooled state. Conventionally, the cooled beverage in a container is put in a heat insulating bag-like case or cooled. The cooled state of the beverage is maintained by replacing the drink with a metal or glass heat insulating water bottle.

On the other hand, as a device for cooling a beverage placed in a bottle or the like, as shown in Patent Document 1 below, a device using an electronic cooling element such as a Peltier element has been proposed. If such a cooling device is used also for a portable bottle container, a drink can be drunk in the always cooled state.

  However, among the conventional methods described above, the method of placing in a heat-insulating bag-like case does not have sufficient cold insulation properties, making it impossible to keep cold for a long time. In addition, the method of replacing with a heat insulating water bottle has a problem in that it is inconvenient to carry in a bag or the like because the size and weight increase.

    In addition, when using a cooling device that uses an electronic cooling element, cooling the entire bottle container with an electronic cooling element increases the overall size of the cooling device and requires a power source with a large current capacity. There is a problem that it is not.

  In view of such a problem, the present invention aims to use a small-sized cooling device, without requiring a large current capacity, and to drink a well-cooled beverage at any time.

In order to solve the above-mentioned problem, a cooling device for a beverage in a container according to claim 1 includes a main body case having a cap portion that can be attached to a drinking mouth of a bottle container at a lower portion of one end portion in the length direction, and the main body case.

The container-packed beverage cooling device of the present invention has the following effects.
That is, in the beverage cooling device for a container according to claim 1, when drinking the beverage from the bottle container, only a small amount of the beverage flowing in the cooling pipe just before entering the mouth is cooled by the electronic cooling element. Therefore, the cooling device is small in size, does not require a large current capacity, and can drink a well-cooled beverage at any time. Further, since the cooling pipes are arranged in a meandering shape or a spiral shape, the length of the cooling pipes in contact with the electronic cooling element is increased, the heat exchange rate is improved, and the beverage cooling efficiency is increased. Furthermore, since the vibrator and the dry battery are provided at the end of the main body case opposite to the side where the cap part is provided, a large vibration is obtained by the vibrator, thereby improving the boundary layer between the inner wall of the cooling pipe and the beverage. The heat exchange rate is further improved by stirring and renewing the beverage boundary layer. Furthermore, the heat-radiating surface of the electronic cooling element also vibrates to improve the heat exchange rate with air, and a heat-dissipating fan is not required simply by providing a heat-dissipating plate.

Further, in the cooling device for a beverage in a container according to claim 2 , a hook embedded with a weight is provided on the opposite side of the main body case where the electronic cooling element , vibrator and dry battery are provided.
