JP3828959B2 - Cooling box for portable cooler boxes for cosmetics, etc. - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cool box of a portable cooler box such as a cosmetic that needs to be stored and stored at a substantially constant temperature.
[0002]
[Prior art]
Some cosmetics and pharmaceuticals are required to be kept in good quality at all times, so it is necessary to store them at an almost constant temperature. It may be stored or used for a long time, and in such a case, it may be difficult to maintain the quality of some cosmetics.
[0003]
As a countermeasure for this, if there is a cooler box for cosmetics that cools the refrigerator with a cooler covered with heat insulating material that contains various cosmetics in bottles, lotions, lipsticks, etc., the quality of these cosmetics will be improved. It can be maintained in a good condition for a long period of time, and it is always cool and cool and comfortable when used.
Conventionally, as exemplified in the invention of JP-A-5-1877 relating to a refrigerator, in a refrigerator or the like in which a heat insulating material is filled between an outer box and an inner box, a cooled electric wire or the like is electrically connected by heat conduction. Since the temperature is also low at the wire outlet portion of the storage case, there is a problem that dew condensation occurs on the wire under the humid conditions of the outside air in contact therewith.
[0004]
In general, when the inner and outer containers are integrally fixed with screws in the cool box of the cooler box, the temperature at the lower end of the screw also decreases due to heat conduction from the head of the screw cooled in the cool box, and Condensation will occur on the outer surface of the outer container.
On the other hand, as described above, in the portable cooler box such as cosmetics to be carried outside and stored in an environment with different temperature conditions, the outer container of the cooler box as described above, that is, Condensation on the outer case is a problem that must be prevented.
[0005]
[Problems to be solved by the invention]
As described above, the present invention includes a heat insulating material provided between the outer container and the inner container, and the inner container of the cool box that cools the inner container is fixed to the outer container through screws. It is an object of the present invention to provide a cold storage box for a portable cooler box such as a cosmetic that can prevent condensation on the screw-fixed back surface of the outer container.
[0006]
[Means for Solving the Problems]
The cooler of the portable cooler box such as the cosmetic of the present invention has a heat insulating material between the bottomed outer container and the inner container, and attaches a cooling device so as to come into contact with the inner container, and has good thermal conductivity. The bottom part of the inner container and the bottom part of the outer container made of material are connected and fixed by screws through screw bosses, and the plate-like body is between the heat insulating material and the bottom part of the outer container, and from the cooling device to the bolt position. Consists of a cool box for portable cooler boxes such as stretched cosmetics.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the cool box of the present invention will be described below with reference to the drawings. The cool box 7 is installed in a portable cooler box 1 such as a cosmetic as shown in FIG. As shown in the figure, it has a power jack (not shown) that can be input from a general power source or a power source of an automobile, a power switch 2 is provided, a lid 3 that can be opened and closed at the top, A mirror 4 is attached and a portable handle 5 is provided.
[0008]
Further, as shown in FIG. 1, a cool box 7 covered with a heat insulating material 6 is provided, and a tray 8 for storing cosmetics and the like can be stored in the cool box 7. An inner lid 9 for maintaining performance can be attached to the upper surface of the cool box 7.
In FIG. 3, reference numeral 10 denotes a cotton space, which can be used as cotton or an accessory case. An air inlet 11 and an air outlet 12 are provided on the outer surface of the cooler box 1.
[0009]
Next, the above-described cool box 7 is the one in which the heat insulating material 6 is provided between the bottomed outer container 15 and the inner container 14 each having a deep bottom, and the inner container 14 is provided with the cool box 7. Since the cooling device 13 composed of a Peltier element that exhibits an efficient cooling effect for cooling is attached, the inner container 14 is formed of a material having good thermal conductivity.
Therefore, the bottom portion of the inner container 14 is provided with concave screw holes as shown in FIG. 1 at the four corners, while the screw boss portion 16 is provided on the inner side of the bottom of the outer container 15 corresponding to these screw holes. The bottom portion of the inner container 14 is fixed to the bottom portion of the outer container 15 via a screw 17 screwed into the screw hole and the screw boss portion 16.
[0010]
In this case, as shown by an arrow X in FIG. 1, the low temperature in the cool box 7 is transmitted to the outer surface portion of the outer container 15 to which the inner container 14 is fixed via the screw 17 through the screw 17. Condensation will occur depending on the temperature and outside air humidity.
Therefore, in the present invention, a plate-like body having good thermal conductivity is stretched between the heat insulating material 6 and the inner surface of the outer container 15. More specifically, the plate-like body 19 is laid on the inner surface of the outer container 15 and stretched so as to be sandwiched by the heat insulating material 6 extending from the heat dissipation plate 18 of the Peltier element as the cooling device 13 to the screw boss portion 16. As the plate-like body 19, for example, an aluminum plate can be used.
[0011]
Therefore, the heat transmitted from the heat radiating plate 18 to the plate-like body 19 is transmitted to the screw boss portion 16 at the bottom on the outer container 15, and the outer container 15 indicated by the arrow X due to the low temperature transmitted from the head of the screw 17. It is possible to prevent condensation on the outer surface. Depending on the degree of condensation, a film-like material such as aluminum foil may be used.
[0012]
【The invention's effect】
According to the cool box of the present invention described above, the inner container and the outer container with the heat insulating material interposed are fixed at the bottom, and the cooler box such as a cosmetic containing the cool box is sufficiently portable. Withstands vibration and the inner container is fixed to the outer container via a plate with good thermal conductivity and screws, preventing condensation due to heat transfer from the fixing screws to the outer surface of the fixed part The function as a portable cooler box for cosmetics and the like can be achieved.
