DETAILED DESCRIPTION Embodiments of the present invention (hereinafter referred to as “examples of the present embodiment”) will be described below with reference to the drawings.

First, the basic principle of the mascara tool for mascara application and eyelash curler with heater mechanism (hereinafter, this may be simply referred to as a mascara tool) according to this embodiment will be described.

The mascara tool includes a mascara accommodating portion and a cap portion.
The mascara accommodating portion is an open container that accommodates the mascara, and an elastic ironing member formed of a material such as rubber is provided on the inner wall near the opening end.

The cap portion closes the mascara accommodating portion when the mascara tool is stored. The cap portion has a protruding portion that protrudes in a stepped manner from the holding portion and the holding portion.
The gripping part is a part held by fingers when performing mascara application or the like with a cap part extracted from the mascara storage part.
The projecting portion has a mascara application area and a hot viewr area for performing mascara application and the like.
The area for applying mascara is, for example, a part that is formed in a comb-like shape on one outer surface of the projecting portion and is used to apply the adhered or impregnated mascara to the eyelashes when extracted from the mascara accommodating portion. When the cap portion is extracted from the mascara accommodating portion, the mascara that is excessively adhered to the mascara application area is rubbed with an elastic ironing member and removed to an appropriate amount.
The eyelash curler area with a heater mechanism (hereinafter referred to as a hot-viewer area) has a built-in electric heater and a built-in heater section in which a plurality of grooves are formed at a predetermined pitch in the axial direction of the surface. (1) a cover and (2) a cover that covers a part or all of the groove so as to be exposed. When using the hot-viewer area by pulling it out of the mascara housing part, apply the heater built-in part, more precisely the groove part of the heater built-in part, with the groove part of the heater built-in part or all exposed from the cover part. A part for curling eyelashes. The groove portion of the heater built-in portion is thin and heat is easily transmitted to the built-in electric heater, and the temperature is relatively high. On the other hand, the portion where the groove portion of the heater built-in portion is not formed (this portion is referred to in the following description). Yamabe) is thick, so the heat of the built-in electric heater is difficult to transfer and the surface temperature is relatively low.
Since the mascara tool is used for both mascara application and the eyelash curler with a heater mechanism (hot buller), there is no need to use two types of cosmetics, a so-called automatic mascara container and a hot buller with a built-in brush and stick. Convenient.

In the storage state where the gripper closes the mascara storage part, the mascara tool covers the groove part of the heater built-in part with the cover part, and in the state of use as a hot viewr that pulls the gripping part out of the mascara storage part, It has a coating and exposure switching mechanism that exposes part or all of the groove (hereinafter, this may be simply referred to as coating and exposure switching mechanism). The exposure by the cover part may be only the groove part of the hot-viewer area, or the entire hot-viewer area including the groove part and the peak part.
The covering and exposure switching mechanism is biased by an actuator. An actuator, in a broad sense, refers to a mechanical element that converts input energy into physical motion. Here, an actuator operates a coating and exposure switching mechanism, and in this case, the input energy is electric energy, electromagnetic energy, or the like. In addition to force energy, hydraulic energy, etc., human power is also included. The same applies to the following examples.

Since the groove part of the heater built-in part is always covered with the cover part in the storage state, the mascara adheres to or accumulates in the groove part of the heater built-in part during storage, which hinders proper curling when used as a hot-viewer. There is no fear, and even if the heater built-in part is heated during storage for some reason, heat transfer to the mascara is reduced, and quality deterioration due to mascara heat is reduced.
On the other hand, when the groove part of the heater built-in part is exposed from the cover part in the use state, even if the hot eyelasher area is accidentally applied to other parts of the face when curling the eyelashes, the mountain part of the heater built-in part is protected. In addition, the groove portion of the heater built-in portion does not directly touch the skin or the like. Further, as will be described later, the surface temperature of the heater built-in portion, more precisely, the surface temperature of the groove portion is set to a low temperature, for example, about 60 to 80 ° C., as long as it does not impair the action of the hot buller. Even if the groove directly touches the skin or the like, there is no fear of burns.

In the basic principle of the mascara tool according to the present embodiment, it is preferable that the mascara tool has an erroneous entry prevention mechanism that prevents the gripping portion from entering the mascara accommodating portion with the heater built-in portion exposed.
When the heater built-in part is exposed from the cover part, the electric heater is usually switched on, but the gripping part cannot enter the mascara storage part due to the action of the erroneous entry prevention mechanism. There is no risk that the mascara will deteriorate due to the heat of the electric heater.
Further, in the basic principle of the mascara tool according to the present embodiment, the mascara tool preferably has an automatic power-off mechanism (automatic switch-off mechanism) of the electric heater.
Even if the power heater is forgotten to be turned off when stored after use, the electric heater can be turned off reliably, and even if the built-in heater is exposed from the cover due to some abnormality, There is no degradation.
The erroneous entry prevention mechanism and the automatic switch-off mechanism may have only one of them or both.

When the mascara tool is used, it is preferable that the surface temperature of the heater built-in portion in the hot-viewer area is 60 to 80 ° C. and the surface temperature of the mascara application area is about 40 ° C. or less.
If the surface temperature of the heater built-in part is extremely lower than 60 ° C, the effect as a hot-viewer may be impaired. On the other hand, if the surface temperature of the heater built-in part is extremely higher than 80 ° C, the eyelashes may be damaged. In addition, there is a possibility that the mascara housed in the mascara housing section may be subjected to a heat change due to the residual heat of the hot builer area immediately after the hot builer area is housed in the mascara housing section after use. In addition, if the surface temperature of the mascara application area is extremely higher than 40 ° C., the mascara accommodated in the mascara accommodation portion by the residual heat of the mascara application area immediately after the mascara application area is accommodated in the mascara accommodation portion after use. May cause heat changes.
The temperature conditions of the hot-viewer area and the mascara application area are determined by the heater conditions such as the heating amount of the electric heater, the layout of the hot-viewer area and the mascara application area, and the material of the protrusion. This can be realized by selecting and determining and determining the thickness of the heater built-in portion that incorporates the electric heater.

Next, regarding the mascara tool according to the first example of the present embodiment, a cross-sectional view showing the storage state of the mascara tool in FIG. 1 or a state before use, and the heater built-in portion in FIG. A description will be given with reference to an external view showing the state where the heater is built and an external view showing the state where the heater built-in portion of FIG. 2B is exposed from the cover member.

The mascara tool 10 includes a mascara accommodating portion 12 and a cap portion 14.
Mascara A is accommodated in the mascara accommodating portion 12. An elastic ironing member 16 made of rubber or the like is provided on the inner wall near the opening end of the mascara accommodating portion 12.
The cap part 14 has a grip part 18 and a projecting part 20 that projects from the grip part 18 in a stepped shape. FIG. 1 shows a state where the protruding portion 20 is inserted into the mascara accommodating portion 12 and the gripping portion 18 closes the mascara accommodating portion 12, that is, a storage state.

The protruding portion 20 includes a rod-shaped member 24 having a heater built-in portion 22 in the vicinity of the tip. Reference numeral 32 denotes an electric heater built in the heater built-in unit 22. A large-diameter portion 26 is preferably provided in a step shape at the tip of the rod-like member 24 at the end of the heater built-in portion 22. On the other hand, a protrusion 28 is also provided at the rear end of the rod-shaped member 24. The rod-shaped member 24 is slidably contacted and fitted by a cover member (cover portion) 30. The rear end (right side portion in FIG. 1) of the cover member 30 is fixed to the grip portion 18. The large-diameter portion 26 and the elastic ironing member 16 constitute an automatic switch-off mechanism that automatically turns off the power switch of the electric heater 32, details of which will be described later.
The heater built-in portion 22 is formed with a plurality of groove portions 22-2 at a predetermined pitch in the axial direction of the surface. A portion where the groove portion 22-2 is not formed becomes a peak portion 22-1. On the outer surface of the cover member 30, the same number of slits 34 perpendicular to the axial direction at the same pitch as the groove 22-2 on the surface of the heater built-in portion 22 are formed in the axial direction in the same number as the groove 22-2. As the heater built-in portion 22 and the cover member 30 slide relative to each other by one slit 34, the groove 22-2 is covered with the cover member 30 and the slit 34 is formed in the heater built-in portion as shown in FIG. 22 is clogged with a thread crest 22-1, or the groove 22-2 of the heater built-in portion 22 is exposed through the slit 34 as shown in FIG. The heater built-in portion 22 and the cover member 30 constitute a hot-viewer area 36.
For example, a comb-tooth-shaped mascara application area 38 is formed on the surface opposite to the side where the slit 34 is formed, which is the other outer surface of the cover member 30.

A slide switch (power switch) 40 as an actuator is provided in the vicinity of the boundary between the grip portion 18 and the protruding portion 20. An angle-shaped member 40 a is provided inside the slide switch 40. The angle-shaped member 40 a is fixed to a fixing member 29 that is fixed to the protrusion 28. By sliding the slide switch 40 to the right in FIG. 1 while applying a predetermined force with fingers, the rod-like member 24 slides one slit 34 leftward, and from the cover member 30 to the groove portion 22-of the heater built-in portion 22. 2 is exposed as shown in FIG. On the other hand, by sliding the slide switch 40 to the left in FIG. 1, the rod-shaped member 24 slides to the right, and the hot-viewer area 36 is in the state shown in FIG.
The slide switch 40 and the protrusions 28 having the angle-shaped members 40 a and the cover member 30 are covered with the heater built-in portion 22 by the cover member 30 in the storage state where the grip portion 18 closes the mascara accommodating portion 12. A covering and exposure switching mechanism that partially exposes the heater built-in portion 22 from the cover member 30 in a use state as a hot buoyer that extracts from the mascara accommodating portion 12 is configured.
Here, the covering and exposure switching mechanism is sufficient if the cover member 30 or the heater built-in portion 22 slides in the axial direction relative to the counterpart, and the cover member 30 is slid instead of the rod-shaped member 24. It may be.
In FIG. 1, reference numeral 42 indicates a battery serving as a power source for the electric heater. However, the power source is not limited to the battery. The description of the detailed structure such as nichrome wire and the electrical connection structure constituting the electric heater is omitted.

The operation of the mascara tool 10 according to the first example of the present embodiment configured as described above will be described.

In a state where the mascara tool 10 shown in FIG. 1 is stored or in a state before use, the grip portion 18 of the cap portion 14 closes the mascara accommodating portion 12, and the mascara A is held in the mascara accommodating portion 12.
At this time, the mascara application area 38 is immersed in the mascara A, and the mascara A adheres or accumulates.
Since the hot-viewer area 36 is covered with the groove portion 22-2 of the heater built-in portion 22 by the cover member 30, the mascara A adheres to the groove portion 22-2 of the heater built-in portion 22 during storage and serves as a hot-viewer. The heat transfer to the mascara A is reduced even if the heater built-in portion 22 is heated during storage for any reason.

When the projecting portion 20 is pulled out from the mascara receiving portion 12 in order to use the mascara tool 10, the mascara application area 38 is rubbed by the elastic squeezing member 16, and the mascara A that adheres excessively to the mascara application area 38 is To the proper amount.

The slide switch 40 is slid by applying a predetermined force to expose the groove portion 22-2 of the heater built-in portion 22 from the cover member 30, and the electric heater 32 is turned on. When the power is turned on, for example, the surface temperature of the heater built-in portion 22 is raised to, for example, about 70 ° C. and maintained at that temperature after a time of about several minutes.
The heater built-in portion 22 heated through the slit 34 of the cover member 30 in the hot-viewer area 36 is applied to the eyelashes to curl the eyelashes. At this time, since the portion other than the exposed groove portion 22-2 of the heater built-in portion 22 is covered with the cover member 30, the groove portion 22-2 of the heater built-in portion 22 does not touch any part of the face other than the eyelashes.

After curling the eyelashes, the mascara application area 38 maintained at a temperature of 40 ° C. or lower is applied to the eyelashes to apply mascara A to the eyelashes.
The curling and mascara application may be in reverse order.

When the curling and mascara application is finished, the slide switch 40 is slid by applying a predetermined force, the electric heater 32 is turned off, and the portions other than the heater built-in portion 22 are covered with the cover member 30 to accommodate the mascara.
