It is CC sectional view taken on the line in (A) (C). 3 is a partially enlarged sectional view of FIG. 1B, FIG. 4 is a sectional view taken along line IV-IV in FIG. 3, FIG. 5 is a sectional view taken along line VV in FIG. is there.

  In FIG. 1, reference numeral 10 denotes a cylindrical grip portion having one end closed, and has a thickness (for example, a diameter of about 1.5 cm) that allows the user to hold the pen on the fingertip. A battery (single type) 12 is accommodated in the grip portion 10. Reference numeral 14 denotes a switch. A brush holding portion 16 is fixed to the upper end of the grip portion 10. The brush holding portion 16 is a plug portion 18 whose lower end closes the upper end opening of the grip portion 10, and a small-diameter cylindrical portion 20 extending from the center of the upper surface of the plug portion 18 in the longitudinal direction of the grip portion 10. A wiring hole 22 is formed in the brush holding portion 16 so as to open at both upper and lower ends along the central axis.

  Reference numeral 24 denotes a cylindrical brush portion. The cylindrical brush portion 24 is made of a heat-resistant flexible resin, and a large number of protrusions 26 are integrally formed on the outer periphery thereof in a substantially stab-like shape. The stab-like protrusion 26 is sufficiently thin and flexible. As shown in FIG. 2A, the cylindrical brush portion 24 is formed with a large number of cuts 30 that are positioned symmetrically with respect to the center line 28 and arranged in two rows in the longitudinal direction.

  This notch 30 is for facilitating the bending of the cylindrical brush portion 24, and opens widely on the outer peripheral surface of the cylindrical brush portion 24, and this opening is perpendicular to the width direction (longitudinal direction of the cylindrical brush portion 24). The direction is a substantially double circle (see FIG. 2B). The phantom line in FIG. 3 indicates the curved position of the cylindrical brush portion 24. In this embodiment, the notch 30 passes through the wall (wall forming the cylinder) of the cylindrical brush portion 24 and communicates with the inside of the cylinder. That is, it is a hole. The upper end of the cylindrical brush part 24 is closed and the lower end is open.

  A temperature sensor 32 is attached to the outer periphery of the lower portion of the cylindrical brush portion 24, and a lower portion of the sensor 32 is an insertion portion 34 that is inserted into the cylindrical portion 20 of the brush holding portion 16. Here, the temperature sensor 32 is in the form of a tape that utilizes the thermal effect (liquid crystal thermography) of the liquid crystal, and the color of the reflected light changes depending on the temperature change. Therefore, the temperature of the cylindrical brush part 24 can be known by confirming this color.

  Reference numeral 36 denotes a heating element that can be plastically deformed. As shown in FIG. 6, the heating element 36 is obtained by folding one end (upper end) of a coiled nichrome wire 38 and covering the folded straight portion with a heat-resistant insulating tube 40.

  The heating element 36 is inserted into the cylindrical brush portion 24. In actuality, first, both ends of the nichrome wire 38 of the heating element 36 are aligned and inserted into the wiring hole 22 from the upper end of the cylindrical portion 20 of the brush holding portion 16, and connected to the switch 14 and the battery 12 in the grip portion 10. Thereafter, the cylindrical brush portion 24 is mounted on the heating element 36 while being inserted, and the insertion portion 34 is press-fitted into the cylindrical portion 20 of the brush holding portion 16 and fixed. As a result, when the switch 14 is turned on, current can be passed from the battery 12 to the heating element 36 to generate heat. Further, the temperature of the cylindrical brush portion 24 can be known from the color change of the temperature sensor 32.

  Next, an example of usage will be described with reference to FIG. The switch 14 is turned on, and the temperature of the heating element 36 is confirmed by the color of the temperature sensor 32, while the cylindrical brush portion 24 is bent in accordance with the roundness of the eyelid of the user, the alignment of the eyelashes, and the preference. At this time, the heating element 36 is formed by winding the nichrome wire 38 in a coil shape, and has a property of maintaining a bent state, that is, a property of being plastically deformable, so that the cylindrical brush portion 24 maintains a curved state. The cylindrical brush portion 24 can be bent lightly and easily by setting the cut 30 to the inner diameter side or the outer diameter side.

  When curling the upper eyelashes 42, as shown in FIG. 7A, the cylindrical brush portion 24 is applied to the eyelashes 42 from below, and the eyelashes 42 are guided between the stab-like projections 26 and guided upward. As shown in FIG. 7B, air heated by the heating element 36 is cut from the cut (hole) 30 by making the cut (hole) 30 on the inner diameter side of the curved cylindrical brush portion 24 face the eyelash 42. It can be applied well to the eyelashes 42. Therefore, the eyelashes 42 can be curled efficiently and in a short time.

  Similarly, when the lower eyelash 44 is curled, as shown in FIG. 7C, the curved cylindrical brush portion 24 may be brought into contact with the eyelash 44 from above and moved downward. At this time, if the cylindrical brush portion 24 is curved along the curvature of the hairline of the eyelash 44, the notch (hole) 30 opens toward the eyelash 44, and the eyelash 44 is curled efficiently. be able to.
