ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a device for curling eyelashes in an upward curl, and more particularly, to a device which is able to create a desired curl or reshaping in less treatment time and of longer duration than conventional eyelash curlers by either the application of pressure alone or by a simultaneous application of pressure and prescribed heat.
2. Description of Related Art
For many years, various devices for use in the curling of eyelashes have been available in order to satisfy the female's desire for enhanced beauty, especially pertaining to the eyes. Some examples include pincer shaped forming devices whose negative results include the undesirable pulling out of lashes during use thereof. Use of a forming liquid is another method for eyelash shaping, and this method often results in stiff, unnatural looking and feeling lashes.
Efforts to overcome the faults of the aforementioned devices resulted in the development of several eyelash curlers such as Korean Utility Model Nos. 81-2113, 83-1178, and 90-7561. Each of these devices uses a battery heated rod, causing the eyelashes to curl upward by slight pressure at the base of the eyelash. Curlers using only the heated rod method of curling lashes suffer from their inability to form the eyelash into a curved shape that follows the contour of the eye since the heated rod can only lift a segment of lashes at a time, requiring repeated applications that may vary in effectiveness according to the proficiency and/or experience of the user. Under these circumstances, a uniform curling angle across all lashes becomes difficult. Additionally, such eyelash curlers using a heat-generating member for increasing a temperature of the device often cannot control the rise in temperature without specially designed controls or interruption of treatment. This results in both an inconvenient and inefficient operation and excessive battery use. Also, the danger of skin or eyelash burn exists and the user is not able to accurately estimate a remaining battery life of the device.
The inconvenient practice of interrupting the operation of the curler in order to sufficiently cool the over-heated heat-generating member will always be present without a method of determining the remaining battery life and will surely cause a more frequent replacement of batteries.
Additionally, conventional eyelash curlers do not have a function to check usable power remaining in the batteries.
Since such conventional eyelash curlers do not have functions to indicate a temperature status of the heater or a battery power status, improper and/or unsafe operations may result.
That is to say, when the power switch is turned “on” to use an eyelash curler, a heater therein starts generating heat and the temperature of the heater should rise to a predetermined temperature prior to use. However, the conventional eyelash curler can not indicate a heated state of the heater so that during operation, the eyelashes fail to form into a well-curved shape or sometimes eyelashes become burned due to over-heating of the heat-generating member.
Further, since conventional eyelash curlers do not have a function to check the state of batteries therein and to indicate a heater temperature status thereof, there is an inconvenient problem such that the power of the eyelash curlers is occasionally automatically turned off during use.
SUMMARY OF THE INVENTION
The herein described invention is presented to solve the faults of conventional devices for curling eyelashes.
One object of the present invention is to provide an improved device for curling eyelashes which is able to promptly, conveniently and automatically form eyelashes into a curled shape by an application of pressure only.
Yet another object of the present invention is to provide an improved device for curling eyelashes which is able to promptly, conveniently and automatically form eyelashes into a curled shape by a simultaneous application of heat and pressure.
Another object of the present invention is to provide enhanced safety through an improved device for curling eyelashes by preventing over-heating and by automatically controlling the heating temperature of a heat generating member to a suitable temperature for curling eyelashes in a combined application of heat and pressure.
It is still a further object of the present invention to lengthen the expected life span of the batteries through a power saving feature.
A further object of the present invention is to provide an improved device for curling eyelashes which is able to indicate heater status by turning on a red light emitting diode (LED) when the power switch is turned “on” and by subsequently turning on a green LED after the heater is heated to a proper eyelash curling temperature. Also, this invention is able to alert a user to a battery power status by observing LED displays.
A further object of the present invention is to provide an eyelash curler which is simple to manufacture and easy to use.
These, and other objects of the invention are achieved by providing a device for curling eyelashes which enables prompt, convenient, and automatic formation of eyelashes into a curled shape by either a sole application of pressure or by a simultaneous application of heat and pressure. Overheating of the eyelash curler is prevented by automatically controlling the heating temperature of the heater to a suitable temperature for curling eyelashes. The device particularly includes a main body having a handle and a forwardly curved extension part on each side of the main body and sited in an upper part of the handle, the handle portion having optional batteries therein; a forming member installed on the top end of both extension parts, the forming member having an eyelash-line shape and a circular bottom with an opening longitudinally formed therein; a heating member for heating the eyelash opening part of the forming member; a pressurizing member movable up and down installed between extension parts of the main body and having a silicon pad attached to an upper part thereof, the silicon pad conforming closely to the lower part of the forming member; a rising and falling member installed on the main body for raising the pressurizing member; a power switch for controlling the heating member installed on the main body; and an indicating lamp representing the state of power installed on the main body.
Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the inventions, are given by way of illustration only since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
