Abstract

The mascara applicator includes: a container 1 for housing mascara liquid; an application body 2 to be attached to and detached from the container 1; and a shaping body 3 to be attached to and detached from the application body 2. The application body 2 includes an application rod 11 in a shape of a hollow shaft to be inserted into the container 1 and an application portion 12 provided at an end portion of the application rod 11. The shaping body 3 includes a shaping rod 21 to be housed by insertion into the application rod 11, a heating shaping portion 22, and a heater 29. The heater 29 can be switched between an OFF state and two stages of ON states. A heat generating temperature of the heater 29 in a state in which the shaping body 3 is attached to the application body 2 is set to be lower than a heat generating temperature of the heater 29 in a state in which the shaping body 3 is detached from the application body 2.

First claim

The invention claimed is:

1. A cosmetic tool system comprising:
a main body portion forming a proximal end of the cosmetic tool for grasping by a user;
a heating rod provided at a distal end of the main body portion and extending distally away from the main body portion, the heating rod having a heating portion formed at a distal-most portion thereof, the heating portion including a heater disposed within the heating portion;
at least two combing attachments having a plurality of comb teeth or bristles on an exterior surface thereof for combing and/or applying a composition to eyelashes, the at least two combing attachments being detachably coupled to the main body portion or the heating rod such that only one of the at least two combing attachments can be coupled at a time, the at least two applicator attachments include a first combing attachment and a second combing attachment, wherein:
the first combing attachment is detachably coupled to the main body portion through a first connection structure such that when coupled, the first combing attachment covers the heating rod and heating portion thereof; and
the second combing attachment is detachably coupled to the heating rod through a second connection structure such that when coupled, the second combing attachment covers the heating portion and a majority of the heating rod is exposed;

each of the at least two combing attachments having a sensor structure at a connection portion between the respective combing attachment and the main body portion or the heating rod, the main body portion having a sensor structure at the connection portion thereof which cooperatively functions with the sensor structure of the first combing attachment to sense whether or not the first combing attachment is attached to the main body portion and the heating rod having at least one sensor structure at the connection portion thereof which cooperatively functions with the sensor structure of the second combing attachment to sense whether or not the second combing attachment is attached to the heating rod;
wherein the heater is configured to set a first heating temperature of the heating rod such that the heating rod is heated at the first heating temperature when the first combing attachment is sensed to be attached to the main body portion,
the heater is configured to set a second heating temperature of the heating rod such that the heating rod is heated at the second heating temperature when the second combing attachment is sensed to be attached to the heating rod, and
the first heating temperature is different from the second heating temperature.

2. The cosmetic tool according to claim 1 ,
wherein
the heating portion is formed as a heating shaping portion for shaping eyelashes,
the first combing attachment is formed as an application body for applying mascara liquid,
the application body having:
a cap to be attached to the main body portion by the first connection structure,
an application rod in a shape of a hollow shaft supported by the cap, and
an application portion provided at an end portion of the application rod, and

an outer face of the heating shaping portion is covered with the application portion in a state in which the application body is attached to the main body portion.

3. The cosmetic tool according to claim 1 ,
wherein the heating rod extends along a longitudinal direction thereof, having a proximal end portion and a distal end portion in the longitudinal direction wherein the proximal end portion is closer to the main body portion than the distal end portion,
the heating portion is disposed at the distal end portion of the heating rod and formed as a heating shaping portion for shaping eyelashes,
the second attachment is formed as an eyelash shaping body for shaping the eyelashes,
the eyelash shaping body having:
a comb frame that is configured to be attached to the heating shaping portion by the second connection structure and
a shaping comb portion that is provided to an outer face of the comb frame to shape the eyelashes, and
an outer face of the heating shaping portion is covered with the comb frame in a state in which the eyelash shaping body is attached to the heating rod.

4. The cosmetic tool according to claim 1 ,
wherein the first sensor structure is formed by paired connection terminals provided to the main body portion and the sensor structure of the first combing attachment is a conductive terminal and
the conductive terminal makes the paired connection terminals electrically continuous with each other so that an attached state of the first combing attachment is sensed in a state in which the first combing attachment is attached to the main body portion.

5. The cosmetic tool according to claim 1 ,
wherein the first sensor structure is formed by a light sensor provided to the main body portion and the sensor structure of the first combing attachment is a light shielding body and
a light receiving state of the light sensor is switched by the light shielding body so that an attached state of the first attachment is sensed in a state in which the first attachment is attached to the main body portion.

6. The cosmetic tool according to claim 1 ,
wherein the first sensor structure is formed by a reed switch provided to the main body portion and the sensor structure of the first combing attachment is a magnet and
the reed switch is switched by the magnet so that an attached state of the first attachment is sensed in a state in which the first attachment is attached to the main body portion.

7. The cosmetic tool according to claim 1 ,
wherein the second sensor structure is formed by paired connection terminals provided to the heating rod and the sensor structure of the second combing attachment is a conductive terminal and
the conductive terminal makes the paired connection terminals electrically continuous with each other so that an attached state of the second attachment is sensed in a state in which the second attachment is attached to the heating portion.

8. The cosmetic tool according to claim 1 ,
wherein the second sensor structure is formed by a light sensor provided to the heating rod and the sensor structure of the second combing attachment is a light shielding body and
a light receiving state of the light sensor is switched by the light shielding body so that an attached state of the second attachment is sensed in a state in which the second attachment is attached to the heating portion.

9. The cosmetic tool according to claim 1 ,
wherein the second sensor structure is formed by a reed switch provided to the heating rod and the sensor structure of the second combing attachment is a magnet and
the reed switch is switched by the magnet so that an attached state of the second attachment is sensed in a state in which the second attachment is attached to the heating portion.

10. The cosmetic tool according to claim 1 , wherein
the heater sets another heating temperature of the heating rod, which is different from any of the first and second heating temperatures, when none of the first and second attachments is sensed and while power is on to the heater.

11. The cosmetic tool according to claim 1 , further comprising:
a third combing attachment having a hollow frame with a plurality of comb teeth or bristles on an exterior surface thereof, the third combing attachment is detachably coupled to the heating rod through a third connection structure such that when coupled, the heating portion is disposed within the hollow frame of the third combing attachment and a remaining portion of the heating rod is exposed;
and the third combing attachment having a sensor structure at the third connec
