The cooling of internal liquid is promoted by rotating the rotating body 11.

Description

  The present invention relates to a device for cooling a liquid in 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.

  However, for infants who want to have milk at night and cry, it is important to keep the 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.

  Thus, requiring a complicated procedure for cooling is not desirable for a frequently used feeding apparatus. Considering that the sucking period is about one year, it is sought to prepare expensive instruments, and the ease of cleaning is an important factor to keep the body hygienic. Therefore, a simple cooling device that does not take time and can easily achieve an appropriate temperature in a short time is desired.

  Then, an object of this invention is to provide the baby bottle cooler which can cool a liquid to a suitable temperature simply and quickly.

  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.

  ADVANTAGE OF THE INVENTION According to this invention, the baby bottle cooler which can cool a liquid to appropriate temperature simply and quickly can be provided.

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

<First embodiment>
Fig.1 (a) is sectional drawing of the baby bottle cooler 1 which concerns on 1st embodiment of this invention.

  As shown in FIG. 1A, the baby bottle cooler 1 according to one aspect of the present invention includes a rotating body 11 and a rotating table 12 on which the rotating body 11 is placed.

  The rotating body 11 is formed to have a cylindrical cooling cylinder 111 having a bottom surface at one end, and a rotating shaft 121 for connecting the rotating body 11 to the rotating table 12. The cooling cylinder 111 is formed in a shape (for example, a cylindrical shape) that comes into contact with the outer surface when the baby bottle A is fitted. The cooling cylinder 111 may be made of any material having a high thermal conductivity, and examples thereof include metals such as aluminum and stainless steel.

  The turntable 12 is, for example, a circular pedestal, and a ball bearing 122 is fixed at the center thereof. The ball bearing 122 further has a through hole (not shown) for the bearing at the center thereof, and supports the rotating body 11 by connecting the rotating shaft 121. One end of the rotating shaft 121 is fixed to the center of the bottom surface of the rotating body 11, and the other end is inserted through a ball bearing 122 into a bearing hole 123 provided in the rotating table 12. Therefore, the rotator 11 is pivotally connected to the turntable 12 with the rotation axis 121 perpendicular to the horizontal plane as the center of rotation.

  In such a baby bottle cooler 1, when the baby bottle A containing a liquid that requires cooling is inserted into the cooling cylinder 111 of the rotating body 11 that has been cooled in advance by a freezer or a refrigerator, the rotating body 11 is rotated. The baby bottle A rotates with the rotation of the body 11, and the liquid inside also flows moderately. Thereby, since it becomes difficult to produce a boundary layer between the baby bottle A and the liquid, the heat exchange efficiency is increased, and the liquid inside is quickly cooled.

  As described above, depending on the heat transfer by the natural convection of the liquid, a cooling time is required. However, by rotating the baby bottle A, the liquid inside is appropriately stirred and the efficient heat exchange is promoted. Thereby, the user can cool the liquid quickly and easily.

  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 surface of the rotating body 11 or the rotating table 12 may be enhanced in appearance by applying paint, color treatment, hair transplantation, or applying cloth or skin. In addition, by configuring the rotating body 11 and the turntable 12 so as to be detachable, the cooled rotating body 11 can be replaced at any time and more efficient cooling can be performed. Further, in order to prevent only the rotating body 11 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 11. As the ball bearing, a thrust ball bearing is effective.

<Modification 1>
FIG.1 (b) is sectional drawing of the baby bottle cooler 1a which concerns on the modification 1 of 1st embodiment of this invention. As shown in FIG.1 (b), the baby bottle cooler 1a has the rotary body 11a which provided the cold insulating material 112 inside the cooling cylinder 111a. The cold insulating material 112 is provided so as to be detachable from the cooling cylinder 111a, and only this can be removed and cooled in a refrigerator or a freezer. As the cold insulating material 112, a gel agent (propylene glycol or the like), a superabsorbent polymer polymer (sodium polyacrylate), or a natural polymer that can be used after being cooled or frozen can be used. Moreover, it is also possible to use salt water (melting | fusing point-22 degreeC of a saturated salt solution).

  In addition, although the cold insulating material 112 is used only for the wall surface of the cooling cylinder 111a here, you may utilize for the bottom face. Moreover, it is good also as a structure wound around the cooling cylinder 111a. Moreover, when using such a cold insulating material 112 inside, it is desirable to use a material with low heat conductivity for the cooling cylinder 111a. Furthermore, the cooling cylinder 111a and the cold insulating material 112 may be integrally formed.

<Modification 2>
Moreover, the rotary body 11 does not necessarily have such a shape. FIG. 2 is a perspective view of a baby bottle cooler 1b according to Modification 2 of the first embodiment of the present invention. As shown in FIG. 2, the baby bottle cooler 1 b has a rotating body 11 b in which a cooling cylinder 111 b is provided that is provided with a rotary hinge 113 in the longitudinal direction of the cooling cylinder 111 and can be opened and closed. The cooling cylinder 111b further includes an optional fastener 114, and can be fixed so that the baby bottle A is sandwiched inside. Here, although the cooling cylinder 111b is shown as a plate shape, it may have a shape such as a mesh or a net as long as the cold insulating material 112 can be held. Further, the cold insulating material 112 may be formed in a bag shape to wrap the baby bottle A.

  According to such a structure, the operation | work which installs the baby bottle A in the cooling cylinder 111b becomes easy. Further, since the cooling cylinder is tightened in the circumferential direction by the fastener 114, the cold insulating material 112 is in close contact with the baby bottle A without any gap, and the cooling effect is further enhanced.

<Second Embodiment>
FIG. 3 is a perspective view of the baby bottle cooler 2 according to the second embodiment of the present invention. Hereinafter, the same symbols are attached to components having the same configurations as those of the above-described embodiments and modifications, and detailed description thereof is omitted.

  The baby bottle cooler 2 includes a receiving base 21 for placing the baby bottle A and the rotating body 11b, and a support base 22 that supports the receiving base. The cradle 21 places the baby bottle A held on the rotating body 11b in a state where the baby bottle A is inclined with respect to the horizontal plane. This can be done by providing a ball bearing 122 and a bearing hole 123 (not shown) in the cradle 21 and fitting a rotating shaft formed on the bottom surface of the rotating body 11b. Alternatively, a rotating plate is provided on the upper surface of the ball bearing 122, and the bottom surface of the rotating body 11b is placed on the rotating plate and rotated.

  The cradle 21 includes a gear 211, a knob 212, a spring 213, and a roller 214. When the user turns the knob 212, the gear 211 that receives the rotation winds the spring 213. The mainspring 213 is stored. The mainspring 213 gradually releases the accumulated force and rotates the roller 214 for a certain time (for example, 3 minutes). The roller 214 is formed in parallel with the central axis of the rotating body 11b and the cooling cylinder 111b, and transmits its rotation to the rotating body 11b. As a result, the rotating body 11b rotates on the cradle 21 with the rotating shaft 121 tilted with respect to the horizontal plane as the center of rotation. Of course, any drive mechanism may be used. For example, the roller 214 may be rotated by a motor instead of the mainspring.

  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 power accumulated by the mainspring 213 becomes rotational energy, the user does not have to wait until the cooling is completed, and can perform it simultaneously with other work.

  In addition, it is good also as a structure that a music flows with a music box etc. according to rotation of the mainspring 213. FIG. Thereby, the user can know by sound that the cooling is finished. Further, by providing the circuit board 221 on the support base 22 and the temperature sensor 215 in the cooling cylinder, sound may flow when the liquid inside is cooled to a predetermined temperature. Furthermore, a liquid crystal temperature sensor can be attached to the cooling cylinder or baby bottle A so that the appropriate temperature can be identified by color.

<Third embodiment>
FIG. 4A is an exploded explanatory view of the cooling cylinder 31 used in the baby bottle cooler 3 according to the third embodiment of the present invention, and FIG. 4B is the third embodiment of the present invention. It is a perspective view of the baby bottle cooler 3 concerned. As shown in FIGS. 4A and 4B, the baby bottle cooler 3 includes a cooling cylinder 31 and a receiving base 32 that detachably supports the cooling cylinder 31.

  The cooling cylinder 31 is a hollow cylinder that is divided into two in the vertical direction, and includes a main body member 31a for covering the lower side of the baby bottle A and a lid member 31b for covering the upper side. The cradle 32 includes two receiving members 321 a and 321 b that receive the cooling cylinder 31. The receiving member 321a receives the tapered extension portion 311 provided on the bottom surface of the main body member 31a of the cooling cylinder 31 in the groove 322a and supports it. The other receiving member 321b receives and supports the groove 322b carved in the lid member 31b of the cooling cylinder 31.

  In addition, the cradle 32 includes a rotation lever 322 and a roller 323 connected via a rotation crank 321 to rotate the cooling cylinder 31. When the rotation lever 322 is rotated, the rotation is transmitted to the roller 323 via the rotation crank 321. The roller 323 is in contact with the cylindrical end portion 312 of the extending portion 311, and rotates the cooling cylinder 31 around an axis parallel to the horizontal plane. The forward rotation and the reverse rotation can be arbitrarily changed according to the rotation direction of the rotating crank.

  According to such a configuration, when the baby bottle A is rotated sideways, the liquid inside is moderately agitated to promote efficient heat exchange. Thereby, the user can cool the liquid quickly and easily.

<Fourth embodiment>
FIG. 5 is a front view of the baby bottle cooler 4 according to the fourth embodiment of the present invention. As shown in FIG. 5, the baby bottle cooler 4 includes a rotating body 41 that houses the cooling cylinder 111 and a rotating table 42.

  The turntable 42 includes a U-shaped member 421 and a ring-shaped member 422 fixed to the two sides of the member 421 with screws 423. The member 422 can be fixed obliquely with respect to the two sides of the member 421 by fitting the cooling cylinder 111 inside thereof. Such a rotating body 41 rotates in a state where the central axis of the cooling cylinder 111 is inclined with a rotation axis 121 perpendicular to the horizontal plane as a rotation center.

  In such a baby bottle cooler 4, when the baby bottle A is inserted into the cooling cylinder 111 and the rotating body 41 is rotated, the baby bottle A rotates and the liquid inside is greatly stirred, and the heat exchange efficiency is further increased. The liquid inside increases quickly. In addition, although it is the structure which rotates the rotary body 41 by hand here, you may use the accumulation | storage force by an electric type or a spring.

<Fifth embodiment>
FIG. 6 is a front view of the baby bottle cooler 5 according to the fifth embodiment of the present invention. As shown in FIG. 6, the baby bottle cooler 5 is such that the rotating base 11 rotates the rotating body 11 as in the first embodiment, but the mechanism is different.

  The rotating body 11 is connected to the turntable 52 by a rotating shaft 521. The turntable 52 includes a rotation lever 522, a rotation crank 523, and two gears 524 and 525. When the rotating lever 522 is rotated, the rotation is transmitted to the gear 524 via the rotating crank 321. The gear 524 rotates the gear 525 that meshes with itself, and the rotation is transmitted to the rotating shaft 521 to rotate the rotating body 11.

  According to such a configuration, the user can easily rotate the rotating body with the rotary lever. The forward rotation and the reverse rotation can be arbitrarily changed according to the rotation direction of the rotating crank.

<Modification 3>
In order to further increase the stirring of the rotating body 11, a rotating mechanism as shown in FIG. 7 may be used. FIG. 7 is an explanatory diagram of a rotation mechanism according to Modification 3 of the fifth embodiment of the present invention.

  Specifically, by providing a plate cam 521a having an eccentric disc around the rotation shaft 521, the spring force of the holding spring 521b that contacts the plate cam 521a changes periodically. As a result, the holding spring 521b periodically accelerates and decelerates the plate cam 521a, and rotates the rotating shaft 521 in a shift manner. When a multi-stage gear is provided, the fluctuation cycle can be changed depending on which gear is provided with such a mechanism. As a result, the internal liquid is prevented from rotating integrally with the surroundings, a boundary layer is hardly formed between the liquid and the liquid, and heat exchange is more efficiently promoted. Thereby, the user can cool the liquid quickly.

<Modification 4>
The rotating mechanism is not limited to the above, and may be configured to be capable of automatically stirring using a motor or the like. FIG. 8 is a cross-sectional view of a baby bottle cooler 5a according to Modification 4 of the fifth embodiment of the present invention.

  Specifically, the turntable 52a includes a switch 526 that switches on / off of rotation, a motor 527 that rotates the gear 524 and the gear 525 in conjunction with the switch, and a battery 528 that supplies power to the switch 526 and the motor 527. And further comprising. According to such a configuration, since the motor 527 automatically rotates the gear, the user can save the trouble of rotating the rotating body.

  Further, by providing the music box 540 operated by the motor 527, the user can know that the motor is being driven. Furthermore, it is possible to employ a configuration in which the motor is automatically stopped by a timer or a temperature sensor. At that time, the music box 540 also stops at the same time as the motor stops, so that the user can quickly know that the cooling has ended.

<Modification 5>
In addition, it is good also as a structure which provides a rotation mechanism in the rotary body 11 side. FIG. 9 is a cross-sectional view of a baby bottle cooler 5b according to Modification 5 of the fifth embodiment of the present invention.

  The baby bottle cooler 5 b includes a rotating body 51 b including a cooling cylinder 111 b and a rotating table 52 b, and the rotating shaft 521 is fixed to the rotating table 52 b via a ball bearing 122. The rotating body 51b includes a switch 526 for switching on / off of rotation, a motor 527 for rotating a gear 529a for rotating the rotation shaft 521 in conjunction with the switch, and a battery 528 for supplying power to the switch 526 and the motor 527. And further comprising. The gear 529a rotated by the motor 527 transmits the rotation to the meshing gear 529b and rotates the rotating shaft 521 fixed thereto. A temperature sensor 530 is provided in the cooling cylinder 111b, and when the liquid inside is cooled to a predetermined temperature, the fact is notified by voice.

  The baby bottle cooler according to the present invention has been described above. According to the baby bottle cooler according to the present invention, since the baby bottle A rotates and the liquid inside is stirred, a boundary layer is hardly formed between the baby bottle A and the liquid, and the heat exchange efficiency is increased. . As a result, the liquid inside is quickly cooled.

  The rotation direction of the rotating body is not limited to one direction, and may be configured to periodically rotate in the reverse direction. For example, forward rotation and reverse rotation of a certain period may be repeated by simply rotating the rotating crank in one direction. Moreover, it is also possible to employ a configuration in which the motor automatically performs forward rotation and reverse rotation at a constant cycle. Furthermore, it is good also as a structure which does not provide a rotation mechanism but cools only with a cooling cylinder.
