Description

The present invention relates to a thermometer attached to the outside of a baby bottle and measuring the temperature of milk inside the baby bottle.

Conventionally, in order to measure the temperature of milk in a baby bottle, a baby bottle having a thermometer attached to the inner wall of the baby bottle (see, for example, Patent Document 1), the inside of the baby bottle via a good heat conductive film. There are thermometers that detect the temperature of milk (see, for example, Patent Document 2), and thermometers with a metal plate and liquid crystal attached to the outside of a baby bottle (see, for example, Patent Document 3).

In order to prepare baby's milk, it is necessary to pour boiling water of 70 degrees or higher into a baby bottle containing powdered milk and cool it to an appropriate temperature of about 40 degrees. It is also a busy time for the mother to prepare milk for the baby, and during that time, cool the hot milk with cold water for a short time, check the temperature of the baby bottle by hand, and cool it again with cold water. Finally, drop a few drops of milk on the skin of your wrist and check that you are breastfeeding. This is a heavy burden for mothers because it takes time and effort when they are busy and they have to prepare milk many times day and night. To reduce this burden, there are thermometers that measure the temperature of milk.

A thermometer that installs a thermometer inside the baby bottle and measures the temperature of the milk put in the baby bottle can accurately measure the temperature of the milk, but since the thermometer is installed inside the baby bottle, it is hygienic. (See, for example, Patent Document 1). When measuring by attaching a thermometer to the outer surface of the baby bottle, it is impossible to detect the temperature at a practical level because the heat conductivity of the baby bottle is low and the thermometer is in contact with cold water, so the temperature is directly inside the baby bottle. There is a thermometer in which a thin film with high thermal conductivity and a temperature sensitive part in contact with it are attached to the nipple part without inserting a meter. Even in this thermometer, since the thin film comes into contact with milk, care must be taken for hygienic handling (see, for example, Patent Document 2). As a thermometer that measures the temperature of milk without coming into direct contact with the milk in the baby bottle, there is a thermometer in which a metal plate with good heat conduction is brought into close contact with the outer wall of the baby bottle and a liquid crystal that changes color depending on the temperature is attached to the outside thereof (for example, patent). (See Document 3), but there is a problem that the accurate temperature is not displayed when the baby bottle is cooled with cold water.

In order to solve the above-mentioned problems, the thermometer for baby bottles according to the present invention has the following means.

The first means is provided with a temperature-sensitive portion that is in thermal contact with the outer wall of the baby bottle and a transparent heat insulating body that covers the temperature-sensitive portion and adheres to the baby bottle.

The second means is characterized in that the transparent heat insulating body is composed of a container having a transparent upper surface portion facing the lower surface portion in close contact with the baby bottle and a gas enclosed in the container. ..

The third means is characterized in that the transparent heat insulating body is composed of airgel.

According to the first solution, the temperature of the milk in the baby bottle can be measured by a temperature sensitive portion attached to the outside of the baby bottle, and the indicated value can be directly visually observed through the heat insulating body.

According to the second solution, since the heat insulating body is composed of a container and a gas, the temperature sensitive portion can be arranged outside the heat insulating body, but the temperature sensitive portion is further provided inside the heat insulating body. It can also be enclosed.

According to the third solution, since the heat insulating body is a transparent solid substance, the container of the heat insulating body is not always necessary, so that the structure is simplified.

According to the present invention, the temperature of the milk inside the baby bottle can be measured from the outside of the baby bottle by heat-contacting the temperature-sensitive portion to the outside of the baby bottle and bringing the heat insulating body into close contact with the heat-sensitive portion. .. As a thermometer for measuring the temperature of milk, there are a thermometer inserted in a baby bottle and a thermometer for measuring by thermally contacting milk through a good heat conductive thin film. Although they can measure the temperature of milk, they require the thermometer to be sterilized each time breastfeeding, which does not reduce the burden on the mother, but also increases the burden. The liquid crystal attached to the outside of the baby bottle without being covered with insulation cannot measure the temperature of milk under the influence of cooling water.

By bringing the baby bottle thermometer of the present invention into close contact with the outside of the baby bottle and cooling the baby bottle with cold water, the milk can be efficiently cooled to an appropriate temperature in a short time and easily without any trouble. As the material of the temperature sensitive part, a liquid crystal temperature indicating sheet, a bimetal, or an organic liquid is preferable, and these temperature sensitive parts are directly contacted with the outside of the baby bottle or thermally contacted with the outside of the baby bottle via a thin film. By adhering the heat insulating body from above, the temperature sensitive part can accurately measure the temperature of the milk. The measured temperature is displayed on the display and can be seen directly through the transparent insulation.

Since the thermometer for baby bottles of the present invention does not need to be sterilized and is removable, the baby bottle can be easily washed. In addition, since it is removable, it can be attached to a baby bottle that the mother wants to use, so it is also a feature that a specific baby bottle is not selected. From these things, the said problem can be solved.

Is.

Hereinafter, embodiments of the thermometer for baby bottles according to the present invention will be described with reference to FIGS. 1 to 4.

It should be noted that this description is an example showing the scope of claims, and does not mean that the scope of claims is limited to this description.

The first embodiment is an example in which the first and second solutions are carried out, and the structure of the thermometer for baby bottles will be described with reference to FIG.

FIG. 1A is a perspective view showing a baby bottle thermometer 2 in close contact with the baby bottle 1. FIG. 1B is an end view taken along the line AA of FIG. 1A and shows the structure of the heat insulating body 5. The heat insulating body 5 is composed of a container 6 including a side wall 7, an upper surface portion 8, and a lower surface portion 9, and a gas 10 enclosed in the container 6. The temperature sensing portion 3 is in close contact with the lower surface portion 9, and the display portion 4 faces the upper surface portion 8. The temperature measured by the temperature sensing unit 3 is displayed on the display unit 4, and can be visually recognized from the outside of the heat insulating body 5 through the transparent gas 10 and the transparent upper surface portion 8.

The outer shape of the heat insulating body 5 may be a rectangular parallelepiped, an elliptical column, or a cylinder, of which a cylinder is preferable. The width and depth of the upper surface portion 8 and the lower surface portion 9 of the heat insulating body 5 are considered to be 15 mm to 80 mm, of which 40 mm is preferable. The height of the heat insulating body 5 is considered to be 5 mm to 30 mm, of which 20 mm is preferable. As the gas 10, air, nitrogen gas, and argon gas, which are transparent and have low thermal conductivity, can be considered, and of these, air is preferable. The upper surface portion 8 of the container 6 may be a transparent plastic having a low thermal conductivity, but acrylic is preferable among the plastics. Since the heat response of the temperature sensitive portion 3 depends on the heat transfer of the lower surface portion 9, it is desired that the lower surface portion 9 is close to the thermal conductivity of the baby bottle 1 and is as thin as possible. From this, a plastic having high strength can be considered, but among the plastics, a polyethylene terephthalate film is preferable. The thickness of the lower surface portion 9 is considered to be 10 μm to 1000 μm, but is preferably 30 μm. The lower surface portion 9 is preferably transparent, but may be opaque. When the lower surface portion 9 is transparent, in order to improve heat transfer from the baby bottle 1 to the temperature sensitive portion 3, the temperature sensitive portion 3 and the display portion 4 may be arranged outside the heat insulating body 5 and brought into close contact with the baby bottle. can. The side wall 7 has a low thermal conductivity and needs to have sufficient strength to maintain the shape of the heat insulating body 5. The side wall 7 may or may not be transparent. In order to prevent cooling water from entering between the baby bottle 1 and the lower surface portion 9, an elastic material is desirable for the side wall 7, and closed cell type fluorine sponge, silicon sponge, and polyethylene sponge are used as the elastic material. However, it is preferably a silicone sponge. All of the side wall 7 may be sponge, but only the vicinity of the lower surface portion 9 may be sponge.

The second embodiment is an example in which the first and third of the above-mentioned solutions are carried out, and the structure of the thermometer for a baby bottle will be described with reference to FIG.

FIG. 2A is a perspective view showing a baby bottle thermometer 2 in close contact with the baby bottle 1. FIG. 2B is an end view taken along the line AA of FIG. 1A and shows the structure of the heat insulating body 5 (described above). The heat insulating body 5 is a columnar transparent airgel 11. Since airgel is a transparent solid substance, it does not require a container and can be used alone as a heat insulating body 5. Since the wavelength of light scattered in the liquid crystal temperature indicator sheet 12 in close contact with the baby bottle 1 and the airgel 11 changes depending on the temperature of the milk in the baby bottle, the color change of the liquid crystal temperature indicator sheet 12 can be visually observed through the airgel 11. The temperature of the milk can be measured.

The third embodiment is an example in which the first and second solutions are implemented. The temperature-sensitive part is a liquid crystal display sheet, and will be described with reference to FIG.

3 (a), 3 (b), and 3 (c) are end views of AA of FIG. 1 (a) (described above). In FIG. 3A, the liquid crystal temperature indicating sheet 12 which is a temperature sensitive portion also serves as the lower surface portion 9 in FIG. 1B (described above). When the liquid crystal temperature indicating sheet 12 has both water resistance and strength, it can serve as both a temperature sensitive portion and a lower surface portion.

In FIG. 3B, the liquid crystal temperature indicating sheet 12 which is a temperature sensitive portion is in close contact with the upper side of the lower surface portion 9. When the water resistance and strength of the liquid crystal temperature indicating sheet 12 are not sufficient, the liquid crystal temperature indicating sheet 12 can be put inside the heat insulating body 5 to protect it.

In FIG. 3C, the liquid crystal temperature indicating sheet 12 which is a temperature sensitive portion is in close contact with the lower side of the lower surface portion 9. If the liquid crystal temperature indicator sheet 12 to be used has water resistance but is not strong enough, the liquid crystal temperature indicator sheet 12 can be reinforced by the lower surface portion 9.

Example 4 is an example in which the first and second solutions are implemented. The temperature-sensitive part is a glass ball part containing alcohol, and will be described with reference to FIG.

FIG. 4A is a top view of a heat insulating body 5 composed of a gas 10 and a container 6 (described above) for enclosing the gas 10 and a top view of an organic liquid in which alcohol is used as the material of the temperature sensitive portion 3. Yes, FIG. 4 (b) is an end view of AA of FIG. 4 (a). The display unit 4 is a thin glass tube, and has a spiral shape so as to fit inside the heat insulating body 5. Air is used as the gas 10. The temperature sensitive portion 3 is attached to the upper surface of the lower surface portion 9. The upper surface portion 8 is a transparent acrylic plate, and the indicated value of the display portion 4 can be visually recognized from the outside of the heat insulating body 5. Here, a glass container filled with alcohol is used as the temperature-sensitive portion 3, but a bimetal may be used.

An adhesive film 13 having good thermal conductivity is added to the lower surface of the lower surface portion 9, and the heat insulating body 5 is brought into close contact with the baby bottle 1 via the adhesive film 13. A rubber band may be used to bring the heat insulating body 5 into close contact with the baby bottle 1. Further, the heat insulating body 5 may be brought into close contact with the baby bottle 1 by pressing the belt with an adhesive material or the belt with a suction cup attached to the heat insulating body 5 against the baby bottle 1 while pulling. Further, the heat insulating body 5 and the baby bottle 1 may be fixed with clips.
