Here, the inner container 110 is a container for receiving the contents in the cosmetic container, it is cylindrical.

The outer container 112 maintains a predetermined distance from the outer surface of the inner container 110 and accommodates the inner container 110. The outer container 112 has the same shape as the inner container 110 but has an enlarged size thereof. .

Here, the outer container 112 is higher in durability than the inner container 110, it is preferable to apply a material having a low thermal conductivity. This is because the outer container 112 is directly exposed to the outside and is easily exposed to the external shock, and it is necessary to minimize the transfer of external heat into the cosmetic container. Therefore, the material of the outer container 112 may be applied to a synthetic resin such as glass or polyethylene.

In addition, the inner container 110 has a relatively high thermal conductivity, so that the phase change material 60, which will be described below, to easily sense the temperature inside the container, is a metal having a property that is harmless to direct contact with cosmetics, that is, aluminum. It is preferable to set it as metallic substance, such as tin-plated iron and stainless steel.

The partition structure 20 is a structure that partitions a plurality of spaces formed between the inner container 110 and the outer container 112, and is disposed perpendicular to the wall surfaces of the inner container 110 and the outer container 112, Space can be arranged regularly.

The partition wall structure 20 may be applied to various forms such as honeycomb, lattice, and irregular shapes as long as the above object is achieved.

A partial perspective view of the honeycomb sidewall structure 22 that can be applied to the present invention is shown in FIG. 2, and a partial perspective view of the lattice sidewall structure 24 is shown in FIG. 3.

In this case, the filling form may be applied to any one or a mixture of powdered phase change material 62, granular phase change material 64, capsule phase change material. Here, the capsule type refers to a form in which a micrometer level, a capsule of a fine size in a range of 1 to 10 μm, surrounds a phase change material powder or granules.

The phase change material 60 is a latent heat storage material having a large amount of heat absorption and heat release due to high latent heat during phase change, and means a material used for the purpose of storing energy or maintaining a constant temperature.

The phase change material 60 can be divided into organic and inorganic forms. For example, high purity alkanes include normal alkanes such as n-tetradecane, n-pentadecane and n-octadecane, and calcium chloride as a hydrated salt compound. Hydrates, hydrated compounds and mixed compounds of organic compounds can be used.

Types and physical properties of the high purity alkanes are shown in Table 1 below.

Product code Molecular formula Molecular Weight Melting point Latent heat n-Dodecane C12H26 170 g / mol -10 215 kJ / kg n-Tetradecane C14H30 198 g / mol  5 236 kJ / kg n-Pentadecane C15H32 212 g / mol  9 178 kJ / kg n-Hexadecane C16H34 226 g / mol 18 231 kJ / kg n-Heptadecane C17H36 240 g / mol 22 176 kJ / kg n-Octadecane C18H38 254 g / mol 28 241 kJ / kg

Such high purity alkanes are chemically stable, have a long life, are easy to handle, and can be recycled as non-toxic materials.

In the present invention, the temperature control principle inside the cosmetic container according to the application of the phase change material 60 is as follows.

 If the temperature in the cosmetic container is higher than the melting point of the specific phase change material as the external temperature increases, the temperature in the cosmetic container may be lowered by absorbing heat of fusion due to the melting of the phase change material. On the other hand, when the temperature in the cosmetic container is lower than a predetermined range as the external temperature is lowered, as the phase change material solidifies again, it is possible to release the solidification heat to increase the temperature in the cosmetic container.

By the heat absorption or heat release of the phase change material 60, the temperature inside the cosmetic container can always maintain a certain range. According to the proper storage temperature according to the use and properties of cosmetics can be applied to the phase change material 60 having a various melting point, preferably, a phase change material having a melting point of 20 ~ 28 ℃ can be applied.

The nozzle 130 is a passage for pulling up the cosmetics accommodated in the inner container 110, the upper end of which is integrally connected to the pump-type discharge part 150, and the lower end is disposed soaked in the received cosmetics.

The pump-type discharge part 150 includes a pump and a discharge port, and functions to pull up and discharge cosmetics through the nozzle 130 by adjusting the pressure by the pump. This form is a known structure that is applied to a variety of containers such as cosmetics will be omitted a detailed description thereof.

The stopper 140 is provided at the connection portion between the nozzle 130 and the cosmetic discharge part 150, and supports the nozzle 130 and the pump discharge part 150, and at the same time, the inner container 110 and the outer container 112. The inlet of the cosmetic container including a) can be sealed to prevent foreign substances from penetrating into the container or vice versa.

The stopper 140 is transparent and has a pupil formed therein, and may fill the pupil with Zion ink 70.

The Zion ink 70 is an ink that changes color according to temperature change, and is also called a thermochromic pigment, a thermocolor, and a reversible color change is applied to a metal complex salt, a cholesteric liquid crystal, a metamo color, and the like. can do.

When discharging the cosmetics in the container, the Zion ink 70 senses the temperature of the cosmetics passing through the nozzle 130 penetrating the center of the stopper 140, and a color change may occur according to the corresponding temperature. Accordingly, the user can visually check the color change through the stopper 140, and can determine whether the cosmetic of the appropriate temperature is used.

In this case, the color change of the Zion ink 70 generally occurs in the range of about -15 to 70 ° C., and a corresponding color in a specific temperature range may be set by various combinations.
