Description

  The present invention relates to a sake warming device for preventing hot sake from cooling during drinking.

  Conventionally, as disclosed in Patent Document 1, as this kind of liquid warming device, a thermoelectric element, a thermistor, a temperature control unit, and the like are attached to the bottom of the liquid bottle, and the temperature is detected by this thermistor. A technique has been proposed in which a temperature controller adjusts a current flowing from the power supply of the thermoelectric element to the thermoelectric element, thereby controlling the temperature of the bottle to a predetermined temperature.

Further, as disclosed in Patent Document 2, a technique has been proposed in which an air layer is provided between an outer container having a decent shape and an inner container held in the outer container.

  However, in the conventional example, in the technical content disclosed in Patent Document 1, a thermoelectric element, a thermistor, a temperature control unit, and the like are attached to a bottle, so that the configuration of the heat retaining device itself becomes complicated and expensive. . In addition, the inner shape of the sake skirt itself is restricted so that the thermoelectric element can be efficiently brought into contact with the outer surface of the sake bottle, so that there is a problem that the bottle used conventionally cannot be used as it is.

  Further, in the technical content disclosed in Patent Document 2, the outer container has a virtue shape, so that the virtue conventionally used cannot be used as it is. In addition, there is a problem that the heat retention effect is extremely low because the temperature is kept only by the air layer.

  Therefore, the present invention has been devised in view of the above-mentioned circumstances that existed in the past, and a liquid thermal insulation device that can be used as it is, has a high thermal insulation effect, and can be manufactured at low cost. The purpose is to provide.

In order to solve the above-mentioned problem, in the present invention, the inner container is configured to be capable of accommodating the bottle P, and to fill the heat storage material 4 into the inside of the cavity formed on each of the peripheral wall portion and the bottom portion having heat insulation. 2 and an outer container 3 having a heat insulating property, which is formed by sealingly covering the outer peripheral surface of the inner container 2 with a heat insulating air layer 5 interposed therebetween.
The heat storage material 4 can be polyethylene glycol or a gelling agent.

  In the liquid thermal insulation device according to the present invention configured as described above, the inner container 2 filled with the heat storage material 4 is heated to a predetermined temperature by being pre-warmed with hot water or a microwave oven, etc. The sake of the sake bottle P stored in the container 2 is kept warm. Further, the outer container 3 covered in a sealed manner via the heat retaining air layer 5 maintains the heat storage state of the inner container 2 at a constant temperature. In this way, the cooperative action between the heat storage effect of the inner container 2 and the heat retaining effect of the outer container 3 allows the hot sake of the sake bottle P stored in the inner container 2 to be kept warm for a long time.

  According to the present invention, the conventional liquid bottle P can be used as it is, and it can be produced at a high heat retaining effect and at a low cost. In particular, because of the double structure of the inner container 2 filled with the heat storage material 4 and the outer container 3 having the heat insulating air layer 5, the predetermined heat retaining device itself is heated in advance with hot water or a microwave oven or the like. The heat can be stored at the temperature, and the sake of the sake bottle P stored in the inner container 2 can be efficiently kept warm.

  BEST MODE FOR CARRYING OUT THE INVENTION The best mode for carrying out the present invention will be described below with reference to the drawings. Reference numeral 1 shown in the figure denotes a bottle holder for storing sake bottle P in order to prevent hot sake from cooling during drinking. As shown in FIG. 1, as shown in FIG. 1, for example, an inner container 2 formed in a cup shape by a heat-insulating synthetic resin material such as polymethylbenthene, and an outer peripheral surface of the inner container 2 And a heat-insulating outer container 3 covered in a sealed manner. Further, the thickness of each of the peripheral wall portion and the bottom portion of the inner container 2 is slightly increased, and a cavity corresponding to a cup is formed inside the thick portion. A heat storage material 4 such as polyethylene glycol or a gelling agent is filled.

  Further, as a specific assembling structure of the outer container 3 with respect to the inner container 2, an annular stepped portion 6 is provided on the inner peripheral portion of the upper opening edge of the inner container 2, and the upper opening side of the cylindrical outer container 3 has an inner diameter. By folding back in a substantially inverted U-shape toward the direction, an annular flange-shaped annular anchoring portion 7 is formed, and the inner peripheral portion of the lower opening edge of the outer container 3 is tightly aligned with the outer diameter portion of the inner container 2. A slightly thicker fitting portion 8 is formed so as to fit and form a gap for forming the heat retaining air layer 5 between the outer container 3 and the inner container 2. When assembling the inner container 2 to the outer container 3, the upper opening side of the inner container 2 is inserted from the lower opening side of the outer container 3, and the annular anchoring portion 7 of the outer container 3 is inserted into the step portion 6 of the inner container 2. Engage. At this time, the outer diameter portion of the inner container 2 is tightly fitted and held by the thick fitting portion 8 formed on the inner peripheral portion of the lower opening edge of the outer container 3, whereby the outer container 3 and the inner container 2 Thus, an annular warm air layer 5 is formed. In addition, an engagement portion between the annular anchoring portion 7 of the outer container 3 and the step portion 6 of the inner container 2 is fixed with an adhesive or the like as necessary.

  Next, the method of using the structure according to the present invention will be described. First, the inner container 2 filled with the heat storage material 4 is heated to a predetermined temperature by warming it with hot water or a microwave oven. Then, sake bottle P may be stored in inner container 2 to keep the sake of sake bottle P warm. Before storing the bottle P, boiling water may be put in the inner container 2 if necessary. At this time, the outer container 3 covered in a sealed manner via the heat retaining air layer 5 can keep the heat storage state of the inner container 2 at a constant temperature. The sake of the sake bottle P stored in the inner container 2 is kept warm for a long time in cooperation with the heat retaining effect of the container 3.

FIG. 3 is a partial sectional view of a use state showing a best mode for carrying out the present invention.
