Description

  The present invention relates to an apparatus for cooling a liquid such as a baby bottle.

  In the past, it was recommended that hot water of 40-60 ° C. be used as the temperature for dissolving powdered milk for infants. Recently, however, the standard for the temperature of hot water to be melted has changed due to health problems of infants. According to the “Guidelines for Safe Formulation, Storage and Handling of Infant Formulas” published by WHO (World Health Organization) and FAO (United Nations Food and Agriculture Organization) in 2007, “Boiled hot water” After that, the milk powder should be melted at a temperature of 70 ° C. or higher ”. This is because recent studies have found that bacteria harmful to infants can survive in the milk powder and cause infections by those bacteria.

However, it is difficult to cool milk powder melted with hot water of 70 ° C or higher. As a general cooling method, there is a method in which running water is applied uniformly to the entire baby bottle. However, it cools relatively quickly, but it requires a large amount of water because it is done with running water. It is difficult to do it every time you suck. As another method, a method of shaking in a container containing cooling water is conceivable, but it may take time if ice is not used, or it may be too cold if ice is added too much, Adjustment is difficult.
Moreover, in order to melt powdered milk at a temperature of 70 ° C. or higher, it is necessary to handle 80 ° C. hot water in consideration of the warming of the baby bottle. This is hot to hold by hand and takes time to cool down the human skin.

  Thus, for example, Patent Document 1 discloses a cooling device with a built-in temperature sensor for a baby bottle in which a coolant and a temperature sensor are provided in a cooling cylinder and the temperature is notified by an external liquid crystal thermometer.

Patent Document 2 discloses a baby bottle with a cooling device that cools by jetting low-pressure carbon dioxide.
Furthermore, Patent Document 3 discloses a cooling device including an outer container for containing ice and water and an inner container adapted to fit at least a part of the outer container. A beverage bottle of the shape is sealed and cooled. In Patent Document 3, a beverage container is disposed horizontally on a bowl immersed in ice and water, and the beverage container is cooled while being rotated by a roller. However, the beverage container is immersed in the head of the beverage container.

  However, it is necessary to dissolve the milk powder in the baby bottle and quickly put it near body temperature. Especially for infants who want to have milk and cry in the middle of the night, it is important to have a suitable temperature in a short time. In the method as described above, cooling may take some time. Also, it is difficult to check the proper temperature with the eyes because the work is often done in the dark at night.

Furthermore, Patent Document 3 discloses a cooling device including an outer container for containing ice and water and an inner container adapted to fit at least a part of the outer container. Although the bottled bottle is sealed and cooled, it is a large-scale operation and there is no rotation, so cooling cannot be expected in a short time. In addition, in Patent Document 3, a beverage container is placed horizontally on a bowl immersed in ice and water, and the beverage container is cooled while rotating with a roller, but the beverage container is immersed in the head, In the case of a baby bottle, the nipple part is immersed in water and is unsanitary and cannot be used.
Thus, requiring a complicated procedure for cooling is not desirable for a frequently used feeding apparatus. In addition, considering that the feeding period is about one year, it is hesitant to prepare expensive instruments, and easy cleaning to keep the body hygienic and hygiene management during cooling are also important. Is an element. Therefore, a simple cooling device that does not take time and can easily achieve an appropriate temperature in a short time is desired.

  Therefore, an object of the present invention is to provide a baby bottle cooler that can cool a liquid to an appropriate temperature easily, hygienically and inexpensively.

  In order to solve the above-mentioned problems, the baby bottle cooler according to the present invention has a cooling cylinder that covers the baby bottle.

  According to the present invention, it is possible to provide a baby bottle cooler that can be simply and quickly hygienic and can cool a liquid to an appropriate temperature at low cost using home ice or the like.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<First embodiment>
FIG. 1 is a cross-sectional view of a baby bottle cooler 1 according to a first embodiment of the present invention.
As shown in FIG. 1, a baby bottle cooler 1 according to one aspect of the present invention includes a baby bottle table 3 that holds a baby bottle A in a cooling cylinder 4 and stores a cooling medium 9 such as ice or water. Indicates a space. The baby bottle A cools the liquid inside the baby bottle A with a cooling medium 9 such as ice or water disposed in the cooling cylinder 4.

Further, the baby bottle base 3 is a rotating body 2 that rotates. The rotating body 2 is provided with a bearing 6 on the rotating shaft 11 at the lower part of the baby bottle base 3 and holds the upper part of the baby bottle A with the hand 10 so that the baby bottle A is rotated together with the baby bottle base 3. Rotate. By rotating the rotating body 2 in this manner, the liquid inside the baby bottle A gradually rotates and flows moderately, and a boundary layer is hardly formed between the baby bottle A and the liquid, so that the heat exchange efficiency is increased. However, the liquid inside is quickly cooled.
The baby bottle base 3 has a shape surrounding the lower part of the baby bottle, and the cooling cylinder 1 has a cylindrical shape with a bottom that covers the baby bottle A while leaving the head of the baby bottle A. Here, the rotation shaft 11 and the axis of the baby bottle base are made the same, but by changing the rotation of the baby bottle, it is easy to promote stirring of the liquid inside the baby bottle and stirring of the cold insulator in the cooling cylinder.

  Thus, by rotating the place requiring cooling time together with the baby bottle A depending on the heat transfer by the natural convection of the liquid, the liquid inside is also appropriately stirred, and efficient heat exchange is promoted. Thereby, the user can cool the liquid quickly and easily. As the cold insulator, a gel-like cold insulating material, a heat storage material or the like encapsulated in a bag in addition to ice or water, or a capsule-like or microencapsulated one may be used. Moreover, rotation can be continued by forming a turntable heavily with a thick metal.

  The present cooling tool is not limited to the above, and many alternatives, modifications, and variations will be apparent to those skilled in the art.

  For example, the appearance of the cooling cylinder 4 may be enhanced by applying a paint, a coloring process, a flocking process, or applying a cloth or skin. In order to prevent only the rotating body 2 from rotating with respect to the baby bottle A, an annular slip stopper formed of a material such as a resin may be provided at the opening edge of the rotating body 12. As the bearing, a thrust ball bearing is effective.

<Second Embodiment>
FIG. 2 is a sectional view of a baby bottle cooler 1a according to the second embodiment of the present invention. As shown in FIG. 2, the baby bottle cooler 1a is provided with a rotating base 5 at the lower part of the cooling cylinder 4a, and by turning a handle 12 provided on the rotating base 5, the crank 13 is rotated by a rotating shaft 11 via gears 14 and 14a. A rotating body 2a having a structure in which the cooling cylinder 4a is rotated by the gear 15a provided to the lower part of the cooling cylinder 4a via the gear 15 is shown. Moreover, the baby bottle base 3a is provided inside the cooling cylinder 4a, and the baby bottle base 3a is attached by the turntable 5 and the fitting portion 8. The baby bottle base 3a is provided with a fastener 41 for supporting the bottom of the baby bottle A using a leaf spring, for example, so that the baby bottle A is pushed in so that it can be easily fixed by the elasticity of the leaf spring. The rotating body 2a containing a refrigerant-holding body such as ice or water rotates around the baby bottle A and promotes cooling of the liquid inside the baby bottle A. The forward rotation and the reverse rotation can be arbitrarily changed according to the rotation direction of the rotating crank. Here, although the axis of the cooling cylinder 4a is the same as the axis 11, the stirring of the refrigerant retaining body may be promoted by changing the center.

<Third embodiment>
FIG. 3 is a sectional view of a baby bottle cooler 1b according to the third embodiment of the present invention. Hereinafter, components having the same configuration as in the above embodiment are denoted by the same symbols, and detailed description thereof is omitted.

  The baby bottle cooler 1b has a rotating body 2b for rotating the baby bottle A and a cooling cylinder 4b mounted on a rotating table 5a, and a lid 7 is disposed on the upper part. The lid 7 prevents the refrigerant retaining body from jumping out of the rotating body 2b by rotation and prevents the baby bottle from tilting. A battery 32, a motor 31 and an electronic circuit are arranged inside the turntable 5a, and the rotation of the rotating body 2b is started and stopped by SW30.

  Although not shown, the crank or motor may be replaced with a spring or the like for driving.

  According to such a configuration, the baby bottle A is rotated to moderately agitate the internal liquid and promote efficient heat exchange. In addition, since the energy stored by the mainspring becomes rotational energy, the user does not have to wait until the cooling is completed, and can perform it simultaneously with other operations.

  In addition, it is good also as a structure that a music flows with the music box 33 etc. according to rotation of a mainspring. Thereby, the user can know by sound that the cooling is finished.

  In order to further increase the stirring of the rotating body 2b, a transmission unit 20 as shown in FIG. 5 may be used. FIG. 5 is an explanatory diagram of the transmission unit 20 according to the third embodiment of the present invention.

  Specifically, as shown in FIG. 5, by providing a cam 21 having an eccentric disc around the rotating shaft 11, the spring force of the holding spring 22 that contacts the cam 21 changes periodically. As a result, the holding spring 22 periodically accelerates and decelerates the cam 21 and rotates the rotating shaft 11 in a variable speed manner. When a multi-stage gear is provided, the fluctuation cycle can be changed depending on which gear is provided with such a mechanism. Thus, the liquid inside is prevented from rotating integrally with the surroundings, and a boundary layer is not easily formed between the liquid and the liquid is more stirred, and heat exchange is promoted more efficiently. Thereby, the user can cool the liquid quickly.

<Fourth embodiment>
FIG. 4 is a plan view of a baby bottle cooler 1c according to the fourth embodiment of the present invention. As shown in FIG. 4, the baby bottle cooler 1c has a rotating body 2c mounted on a turntable 5b. The rotating body 2c is provided with a baby bottle base 3a inside the cooling cylinder 4c. For example, the meteor gear mechanism 40 is provided so that the cooling cylinder 4c and the baby bottle base 3a change in the opposite direction or the number of rotations. Indicates a rotating object. Further, the cooling cylinder 4c incorporates a SW for rotation, a battery, a motor, and a driving device. Furthermore, an appropriate temperature is notified by providing a temperature sensor 34 near the lower part of the baby bottle A. The temperature sensor 34 is fixed to the cooling cylinder 4c, measures the temperature while sliding the bottom of the center of the baby bottle, notifies not only the appropriate temperature, but also prevents the supercooling by stopping the rotation.

  The rotation mechanism is not limited to the above, and the agitation may be automatically promoted by using a motor or the like that irregularly changes the rotation speed or repeats normal rotation and inversion.

  FIG. 6 is an explanatory diagram of a rotating unit according to the fourth embodiment of the present invention. The explanation of the rotating body 2c using the meteor gear mechanism 40 is shown. An internal gear 18 is provided at the bottom of the cooling cylinder 4c, the sun gear 16 is fixed, the meteor carrier 17 is rotated by rotation of the shaft 11, the internal gear 18 is rotated via the meteor gear 19, and the cooling cylinder 4c is rotated. The meteor carrier 17 is provided with a baby bottle base 3a. Thus, when the shaft 11 is rotated, the baby bottle base 3a is rotated and the cooling cylinder 4c is rotated in the opposite direction. Thereby, stirring of the fluid in the baby bottle A and stirring of the cold insulator can be performed, and cooling can be performed efficiently. When the internal gear 18 is fixed and the shaft 11 is rotated, the shaft and the meteor carrier 17 are rotated. When the baby bottle base 3a is fixed to the shaft 11 and the cooling cylinder is fixed to the meteor carrier 17, the baby bottle base 3a and the cooling cylinder 4c rotate in opposite directions. Thus, the combination of the rotation of the cooling cylinder and the baby bottle base can be selected by utilizing the fact that each rotation changes by fixing any of the internal gear, the meteor carrier, and the sun gear.
