A large number of threads are formed on the outer circumferential surface of the upper part of the container 2 and a plurality of threads are formed on the inner circumferential surface of the cavity of the lower part of the lid 1 to rotate the container 2 in the lower cavity of the lid 1 The container 2 can be joined to the lid 1 by inserting.

Fig. 3 is a plan view of the lid 1 shown in Fig. 1, and Fig. 4 is a bottom view of the lid 1 shown in Fig. The cosmetic case shown in Figs. 1-4 is an example of a case for containing semi-solid cosmetics such as a cold cream, a nutrition cream, etc., and the cylindrical container 2 and the lid 1 are formed in a shape of a rectangular barrel, It will be appreciated by those skilled in the art that the present invention can be easily modified into other shapes,

1, the lid 1 includes a lid housing 11, a marking section 12, a sterilizing section 13, a battery 14, a solar cell 15, a charging circuit 16, A converter 17, an optical sensor 18, a contact sensor 19, and a control unit 110. [ Since most of the components of the present embodiment are applied to the inside of the lid 1, the height of the lid 1 is enlarged so that the components described above can be more clearly expressed. That is, the display unit 12, the sterilizing unit 13, the battery 14, the solar cell 15, the charging circuit 16, the converter 17, the optical sensor 18, the contact sensor 19, 110 may be formed in the form of a thin film, so that the actual lid 1 can be made very thin compared to the shape shown in Fig. The electrical connection between these components is omitted in FIG. 1 to avoid complication of FIG. 1 and is shown in the form of a block diagram in FIG.

The lid housing 11 is a housing of a cylindrical lid 1, one end of which is closed and the other end is open, and on the inner circumferential surface thereof, a plurality of threads for engaging with the container 2 are formed. A circular concave portion for providing a marking portion 12 is formed at the center of the upper surface of the lid housing 11. A rectangular concave portion for mounting a plurality of solar cells 15 is formed on the circumferential surface of the concave portion. And a circular concave portion for providing at least one optical sensor 18 is formed on the outermost side of the circumferential surface. A circular concave portion for providing the sterilizing portion 13 is formed at the center of the bottom surface of the lid housing 11. A rectangular concave portion for providing at least one contact sensor 19 is provided at the edge of the concave portion. .

A battery 14, a charging circuit 16, a converter 17, and a control unit 110 are installed in the hollow portion of the lid housing 11 in a hollow cylindrical shape inside the lid housing 11 do. 1, the charging circuit 16, the converter 17, and the control unit 110 are configured such that the electronic elements constituting each of them are integrated to form a single printed circuit board (PCB) And can be implemented as a single integrated circuit. A disk-shaped partition having an outer diameter equal to the inner diameter of the hollow portion of the lid housing 11 may be placed on the bottom surface of the hollow portion inside the lid housing 11. A battery 14 is installed on the partition, and a disk-shaped partition can be placed on the battery 14. The partition has a circular concave portion for installing the sterilizing portion 13 thereon. A plurality of threads are formed on the outer circumferential surface of each of the compartments and a plurality of threads are formed on the inner circumferential surface of the hollow portion of the lid housing 11 so that the respective compartments are inserted into the hollow portion of the lid housing 11, And can be fixedly coupled to a suitable height of the hollow portion of the housing 11. [

The cover 12 is turned on at the time when the brightness of the periphery of the cover 1 becomes equal to or greater than the critical brightness in accordance with whether power is supplied from the converter 17 controlled by the controller 110, The light for marking the cosmetic case is diverted to the outside of the lid 1 by using the visible ray LED 122 which is turned off based on the time when the lid 1 is separated from the opening of the container 2 . Since the cosmetic case is generally manufactured in a small size that can be held in the hand, the battery 14 installed inside the lid 1 is mainly a coin-type miniature battery. Due to the capacity limitation of the battery 14, only a very small amount of electric energy can be stored in the battery 14 of this embodiment. The visible light LED 122 may be configured to reduce the brightness of the periphery of the cover 1 in order to minimize the consumption of electric energy of the visible light LED 122 that generates light in the visible light range from the electric energy stored in the battery 14. [ Is turned off based on the time point at which the container 2 is opened.

Cosmetic cases are usually mixed with other objects in bags such as women's handbags, shoulder bags, etc., and are small in size and are not easily found when the bag is opened. It takes a bag to look for a cosmetic case, which is a significant inconvenience to the user of the cosmetic case. There are even cases where the contents of the bag are exhausted by inverting the bag to find the cosmetic case. While the bag is closed, light can not enter the inside of the bag, and the light enters the inside of the bag only when the bag is opened. According to this embodiment, since the light is emitted from the cosmetic case inside the bag when the bag is opened, the cosmetic case can be clearly identified from other objects inside the bag.

Even when the bag is opened, the inside of the bag is somewhat dark, so that the user can immediately find the cosmetic case as soon as the bag is opened. Generally, while the bag is closed, the inside of the bag is in a brightness state close to 0 lux, and while the bag is opened, the inside of the bag is in a brightness state exceeding at least 10 lux. In this embodiment, the threshold brightness may be any value between 1 lux and 10 lux. If the critical brightness is any value between 1 lux and 10 lux, the visible light LED 122 is operated at the moment when the bag is opened, and light is emitted from the cosmetic case inside the bag.

On the other hand, the lid 1 may be detached from the container 2 long after the user unpacks the lid 1 from the container 2 immediately after opening the bag. In this case, if the ON state of the visible light LED 122 is continuously maintained from the time when the brightness of the periphery of the lid 1 is equal to or greater than the critical brightness to the time when the container 2 is opened, Can be consumed. It is sufficient that the cosmetic case emits for a period of time such that the user can find the cosmetic case after opening the bag, for example, for 2 to 5 seconds. The visible light LED 122 of the marking section 12 is placed in the container 2 from the point of time when the brightness of the periphery of the lid 1 becomes equal to or higher than the critical brightness in order to further reduce the power consumption of the battery 14. [ The time when the brightness of the periphery of the cover 1 becomes equal to or greater than the threshold brightness may be turned off when the threshold time elapses from the time when the brightness becomes greater than the threshold brightness . For example, the threshold time may be any value between 2 and 5 seconds.

On the other hand, if the length of the section from the time when the brightness of the periphery of the lid 1 is equal to or higher than the critical brightness to the time when the container 2 is opened is less than the critical length, Is turned on at the time when the brightness of the periphery of the container 1 becomes equal to or greater than the critical brightness and is turned off at the time when the container 2 is opened. The fact that the container 2 has been opened means that the user has found the cosmetic case, so there is no need to emit light from the cosmetic case.

Referring to FIG. 1, the marking portion 12 is composed of a glazing panel 121, at least one visible light LED 122, and a printed circuit board 123. According to the embodiment shown in FIG. 1, one visible light LED 122 is applied to the indicator 12, but a larger number of visible light LEDs 122 are applied according to the brightness of each visible light LED 122 It is possible. 2-3, the glazing panel 121 is a flat panel panel attached around the entrance of the concave portion on the upper surface of the lid housing 11, and is provided with a specific pattern of material having a light transmittance higher than that of the surrounding material Respectively. That is, the glazing panel 121 is composed of a central panel of a specific pattern shape having a high light transmittance and a peripheral panel having a low light transmittance which is bonded to and surrounds the central panel. For example, the peripheral panel of the glazing panel 121 may be made of an opaque material and the center panel may be made of a translucent material of a specific color.

Each visible light LED 122 generates visible light from the power output from the converter 17, which is installed on the bottom surface of the concave portion of the upper surface of the lid housing 11 and is controlled by the control unit 110, So that light of a specific pattern is emitted from the pattern panel 121. [ Since the light transmittance of the panel having the specific pattern located at the center of the pattern panel 121 is higher than the light transmittance of the surrounding panel, the specific pattern portion is brighter than the surrounding area when the pattern panel 121 is irradiated with visible light. An example of a specific pattern formed on the pattern panel 121 is a symbol representing a characteristic cosmetics. In Fig. 2-3, "S" is shown as an example of the symbol. Thus, the user can discover the cosmetic case immediately as soon as the bag is opened owing to the brightly shining symbol inside the bag, and the user can be aesthetized with respect to the symbol, so that the brand value of the symbol can be improved. In addition, the user can identify from which symbol the cosmetic case is a cosmetic case.

The printed circuit board 123 is attached to the bottom surface of the concave portion of the upper surface of the lid housing 11 and the visible light LED 122 is mounted on the conductive pattern of the cover plate 11, In the bottom surface of the concave portion on the upper surface of the body. The visible light LED 122 may be electrically connected to the converter 17 through the conductive pattern of the printed circuit board 123. The printed circuit board 123 may not be needed if the visible light LED 122 can be electrically connected directly to the converter 17. [ Meanwhile, as shown in FIG. 1, a diffusion lens that surrounds each visible light LED 122 may be attached to each visible light LED 122. The diffusing lens diffuses the light emitted from the visible light LED 122 so that the light of the visible light LED 122 can be uniformly irradiated to the entire lower surface of the pattern panel 121.

The sterilizing unit 13 is turned on at a time point when the brightness of the periphery of the lid 1 becomes equal to or higher than the critical brightness according to whether or not power is supplied from the converter 17 controlled by the control unit 110, The cosmetics located inside the container 2 are sterilized by using at least one ultraviolet LED 131 which is turned off based on the time when the container 2 is opened by separating the container 2 from the container. As described above, only a very small amount of electric energy can be stored in the battery 14 of the present embodiment. In order to minimize the energy consumption of the ultraviolet LED 131 which generates light in the ultraviolet region from the electric energy stored in the battery 14 in this embodiment, the ultraviolet LED 131 is disposed in such a manner that the brightness of the periphery of the lid 1 exceeds the critical brightness And is turned off based on the time when the container 2 is opened.

 The ultraviolet LED 131 of the sterilizing section 13 is set such that the brightness of the periphery of the lid 1 is lower than the threshold brightness of the ultraviolet light LED 131 of the sterilizing section 13 in order to further reduce the power consumption of the battery 14 similarly to the visible light LED 122 of the marking section 12. [ The time from the time when the brightness of the peripheral area of the cover 1 to the time when the container 2 is opened to the time when the container 2 is opened exceeds the critical time, Can be turned off at the elapsed time. The survival rate of bacteria is known to be exponentially decreased with respect to the product of the intensity of ultraviolet rays and the irradiation time of ultraviolet rays. That is, when ultraviolet rays are irradiated to cosmetics located inside the container 2, almost all the bacteria existing on the surface of the cosmetics die at the moment of irradiation.

For example, the threshold time applied to the ultraviolet LED 131 may be any value between 2 seconds and 5 seconds, which is the same as the threshold time applied to the visible light LED 122. [ The threshold time applied to the ultraviolet LED 131 and the threshold time applied to the visible light LED 122 may be the same to simplify the control operation of the control unit 110. [ Alternatively, the threshold time applied to the ultraviolet LED 131 may be longer than the threshold time applied to the visible light LED 122 in order to improve the sterilizing ability of the sterilizing unit 13.

The ultraviolet LED 131 of the sterilizing section 13 is set such that the brightness of the periphery of the lid 1 is lower than the threshold brightness of the ultraviolet light LED 131 of the sterilizing section 13 in order to further reduce the power consumption of the battery 14 similarly to the visible light LED 122 of the marking section 12. [ The time when the length of the section from the time when the container 2 is opened to the time when the container 2 is opened is equal to or less than the critical time is the time when the brightness of the periphery of the lid 1 becomes equal to or greater than the critical brightness, Off. It is useless to sterilize the cosmetics while the container 2 is open since the cosmetics located inside the container 2 may be contaminated by the user from time to time if the container 2 is opened.

If the user uses cosmetics located inside the container 2 after detaching the lid 1 from the container 2, the cosmetics may be contaminated by the user. If the container 2 is closed by the user joining the lid 1 to the container 2 after the contamination of such cosmetics, the contamination degree of the cosmetic product can be increased due to the propagation of bacteria in the container 2. [ The ultraviolet LED 131 of the sterilizing section 13 is attached to the container 2 by the cover 1 unlike the visible light LED 122 of the marking section 12 for preventing the cosmetic contamination from increasing and sterilizing It is possible to alternately repeat on and off at regular intervals for a predetermined time from the time when the container 2 is sealed. For example, the ultraviolet LED 131 of the sterilizing section 13 can alternately repeat on and off at intervals of 10 seconds for one minute from the time when the container 2 is sealed. The on / off alternation of the ultraviolet LED 131 is an operation for maintaining the sterilizing power for a relatively long time while minimizing power consumption.

 Referring to FIG. 1, the sterilizing unit 13 includes at least one ultraviolet LED 131 and a printed circuit board 132. According to the embodiment shown in FIG. 1, five ultraviolet LEDs 131 are applied to the sterilizing unit 13, but fewer or more ultraviolet LEDs 131 are applied depending on the brightness of the ultraviolet LEDs 131 It is possible. Each of the ultraviolet LEDs 131 generates ultraviolet rays from the power output from the converter 17 which is provided on the bottom surface of the concave portion of the lower surface of the lid housing 11 and is controlled by the control unit 110, To sterilize cosmetics located inside the container 2.

The printed circuit board 132 is attached to the bottom surface of the concave portion of the lower surface of the lid housing 11 and the ultraviolet LED 131 is mounted on the conductive pattern of the printed circuit board 132, And can be installed on the bottom surface of the concave portion on the bottom surface. The ultraviolet LED 131 may be electrically connected to the converter 17 through the conductive pattern of the printed circuit board 132. The printed circuit board 132 may not be needed if the ultraviolet LED 131 can be electrically connected directly to the converter 17. [ 1, a diffusion lens that surrounds the UV LEDs 131 may be attached to the respective UV LEDs 131. As shown in FIG. The diffusing lens diffuses the light emitted from the ultraviolet LED 131 so that the light of the ultraviolet LED 131 can be uniformly irradiated onto the entire surface of the cosmetic.

The battery 14 stores electrical energy. This may be a non-rechargeable primary battery or a rechargeable secondary battery. The lithium-based battery is suitable because the battery 14 of this embodiment requires a high energy density due to the limitation of the size of the cosmetic case. When the battery 14 is a primary battery, there is an inconvenience that the battery 14 needs to be replaced with a new battery when the electric energy stored in the battery 14 is exhausted. On the other hand, when the battery 14 is a secondary battery, it is inconvenient to charge the battery 14 periodically. In order to solve this inconvenience, a docking station for charging the battery 14 may be provided while acting as a pedestal of the cosmetic case.

On the other hand, in an environment where the cosmetic case is mainly provided outside the room, rather than indoors, sunlight may be irradiated on the cosmetic case. In such an environment, the battery 14 may be charged using the light energy of the sunlight irradiated on the lid 1. [ At least one solar cell 15 provided on the upper surface of the lid 1 generates electrical energy from the light energy of the sunlight irradiated on the lid 1 and the battery 14 is charged by the charge And can store the electrical energy generated by the solar cell 15 through the circuit 16. According to the embodiment shown in Figs. 1-3, eight solar cells 15 are provided on the top surface of the lid 1, but depending on the energy conversion efficiency of each solar cell 15, 15) may be installed.

Fig. 5 is a view showing the electrical connection relationship among the components of the lid 1 shown in Fig. The charging circuit 16 converts at least one of the output voltage and the output current of the solar cell 15 to a size suitable for charging the battery 14 under the control of the controller 110. [ The charging circuit 16 may be omitted if the output voltage and the output current of the solar cell 15 are suitable for charging the battery 14. In this case, the output power of the solar cell 15 is controlled by the control unit 110 Can be supplied directly to the battery 14. The converter 17 converts at least one of the output voltage and the output current of the battery 14 into a size suitable for driving the visible light LED 122 and the ultraviolet LED 131 under the control of the controller 110. [ The direct current is output from the battery 14 and the direct current is input to the visible light LED 122 and the ultraviolet LED 131. Thus, the converter 17 is a kind of DC / DC converter. The converter 17 may be omitted if the output voltage and the output current of the battery 14 are suitable for driving the visible light LED 122 and the ultraviolet LED 131. In this case, 110 and may be supplied to the visible light LED 122 and ultraviolet LED 131 directly.

The light sensor 18 is installed at the outermost circumference of the upper surface of the lid housing 11 to detect the brightness of the surroundings of the lid 1 and generates a signal indicating the detection result and outputs the signal to the control unit 110. This optical sensor 18 may be implemented as an illuminance sensor. The contact sensor 19 is provided at the edge of the concave portion of the lower surface of the lid housing 11 to detect whether the container 2 is open by detecting whether the container 2 and the lid 1 are engaged. More specifically, the contact sensor 19 detects whether or not the container 2 is open by detecting whether or not the edge of the concave portion of the lower surface of the lid housing 11 is in contact with the upper end of the container 2, And outputs the generated signal to the control unit 110. [ This contact sensor 19 can be implemented as a miniature pushbutton switch.

The controller 110 controls the charging circuit 16 according to the state of the battery 14 so that the battery 14 can be smoothly charged. For example, in the case of a lithium-based battery, the control unit 110 allows a large amount of current to flow into the battery 14 when the voltage of the battery 14 is low, and when the voltage of the battery 14 approaches the full- And controls the charging circuit 16 so that a small amount of current can flow into the battery 14. [ The controller 110 also controls the battery 12 for each of the indicator 12 and the sterilizer 13 based on at least one of the value of the output signal of the optical sensor 18 and the value of the output signal of the contact sensor 19.
