Description

  The present invention relates to a mascara device for attaching a mascara (decorative material) onto the eyelashes along the curl direction of the eyelashes by automatically rotating the brush hairs.

Mascara is a type of cosmetics that makes your eyelashes appear dark, long, or curled, and is available in three types: liquid, solid, and cream. Is the mainstream and some are transparent.
The mascara is usually stored in a bottomed cylindrical container, and a rod-shaped brush is inserted into the container, and the mascara is attached to the brush hair (see FIG. 2). For example, FIG. ), (B), pulling out the brush 20 from the container and holding it in the hand, applying the brush hair 21 to the eyelash a, and turning the wrist, the brush 20 (brush) along the curl direction of the eyelash a The hair 21) is rotated to apply the mascara b adhering to the brush hair 21 to the eyelashes a.

At this time, for beginners, persons with poor hand movement, and persons with inconvenience in hand movement, the operation of rotating the bristle 21 along the eyelashes a turning the wrist is not easy, and the operation is successful. Can not.
For this reason, various mascara tools for automatically rotating the brush 20 that is the subject of the present invention have been devised (see Patent Documents 1 to 3).

A mascara tool for automatically rotating this type of brush 20 will be described with reference to FIGS. 1 to 4 showing an embodiment according to the present invention. It is generally composed of a rod-shaped brush 20 to be inserted and gripping portions 30 and 40 that rotatably support the brush 20, and a motor 43, a power source (battery) 45 and a control board 44 are accommodated in the gripping portion. It is.
This mascara tool has a gripping part by hand, drives a motor 43 with a switch 46, rotates the brush 20 by this drive, applies the brush hair 21 in the rotated state to the eyelash a, The mascara b is adhered on the eyelash a along the curl direction and the eyelash a is curled. Alternatively, after the brush hair 21 is applied to the eyelash a, the motor 43 is driven to attach and curl the mascara b to the eyelash a.

  Moreover, in order to make the mascara b adhere smoothly to the eyelashes a, there is one that vibrates the brush 20 (see Patent Document 1). The vibration of the brush 20 is performed by the vibration accompanying the rotation of the eccentric vibrator by the rotation shaft provided with an eccentric vibrator (eccentric block) on the rotation shaft of the motor (see FIG. 6 of this application). At this time, there are those that only vibrate the brush 20 and do not rotate the brush 20, and those that vibrate and rotate the brush 20.

The mascara tool for automatically rotating the brush 20 is effective in terms of simplifying the mascara operation, but if the stored mascara b is used up, the mascara tool is all discarded.
Under the growing environmental problems of today, the discarded mascara tools still have a motor 43 and a battery 45 that can be used sufficiently, and the disposal of the motor is a problem.

Moreover, in the mascara device that vibrates the conventional brush 20, the device that does not rotate the brush 20 needs to rotate the wrist (brush 20) to rotate the device (brush 20).
For the mascara tool that vibrates and rotates the brush 20, the rotational speed for obtaining the vibration and the rotational speed for rotating the brush 20 are usually several thousand rpm (several thousand times / minute) for the former vibration. In contrast, the brush rotation is several tens of rpm (several tens of times / minute). For this reason, what rotates the brush 20 itself by the vibration of the conventional brush 20 cannot obtain an appropriate rotation number (vibration frequency) of both, and there is usually a problem that the rotation of the brush 20 is not smooth. . In addition, it can be considered that the rotational speed (frequency) of the eccentric vibrator and the rotational speed of the brush 20 are made appropriate by the speed reducer, but two speeds (shafts) having different rotational speeds are output by the speed reducer. When trying to do so, there is a problem that the speed reducer becomes large. The mascara device is desired to be compact, which is against the request.

  In the present invention, the first problem is to make this kind of mascara device friendly to environmental problems even under the growing environmental problems. The first problem is to make the rotation speed and frequency of the brush 20 appropriate. Let it be the second issue.

In order to achieve the first object, the present invention is that the mascara container and the brush are not easy to wash the attached mascara, so they are discarded or collected, and other motors and the like are It can be reused by the user.
Reusing a durable object such as a motor in this way saves resources and is environmentally friendly. Resource saving and reuse means reducing waste and saving money. In particular, mascara has become a part of women's lifestyles, and environmental friendliness in their lives is a growing awareness of today's ecology.

  Specifically, the present invention provides a bottomed cylindrical mascara storage container, a rod-shaped brush inserted into the storage container, and a handle of the brush rotatably supported coaxially with the opening of the storage container. A cylindrical support portion to be attached and a cylindrical operation portion that is coaxially attached to the cylindrical support portion, the operation portion being provided with a motor, a motor control board, a battery, and an operation switch. By attaching the operation part to the cylindrical support part, the rotation shaft of the motor is detachably connected to the handle of the brush, and the rotational force of the motor is transmitted to the brush.

  With this configuration, the mascara storage container, the brush, and the support portion thereof are discarded, but the operation unit that stores the motor or the like is the support of the parts including the new mascara storage container, the brush, and the support portion thereof. A new mascara tool is constructed by attaching to the part. At this time, if the brushes and the like that are discarded are also collected and reused, resources are further saved (eco-friendly). For collection, eco-points can be given as discount points for new brushes.

  In this configuration, the motor, the motor control board, and the battery are housed in a cylindrical member, and one end portion of the cylindrical member is fitted into the operation portion, and the other end portion of the cylindrical member is connected to the support portion. If the operation part is attached to the support part by being fitted into the support part, the operation part can be easily attached to the support part, and the brush drive part and the operation part are provided in the cylindrical member. Therefore, by further disassembling the cylindrical member, it becomes easy to reuse the motor and the like therein. Further, there is an advantage that the drive unit and the like can be repaired by replacing the cylindrical member. Furthermore, since the motor or the like is housed in the cylindrical member, it is easy to separate them, and the possibility of disposal or reuse is high.

In order to achieve the second problem, the present invention is configured to perform rotation and vibration of the brush by separate motors in view of the trend toward miniaturization of today's small (micro) motors.
Today, small motors are increasingly miniaturized (micro), and less space is required for two motors than the reduction gears that output two rotations (shafts) with different rotation speeds. In addition, both motors can be easily provided on the same axis, and vibrations can be smoothly transmitted to rotating bristles, and a smooth application of mascara due to the vibrations can be obtained. If the center of rotation of the brush and the center of vibration are deviated, the vibration will adversely affect the rotation, such as shake of the center of rotation, and stable rotation cannot be expected.

As a specific configuration of the invention for achieving the second problem, a configuration in which another motor is fixed to the brush hair rotation motor and an eccentric vibrator is provided on the rotation shaft of the other motor is provided. Can be adopted.
Thus, if the two motors are fixed and integrated with each other, the stable rotation and vibration of the brush can be obtained in the same manner as when “rotation” and “vibration” are performed with one motor. At this time, it is preferable that the shaft centers (rotating shafts) of both motors are on the same axis.

  In addition, the said structure which achieves the 1st subject and the said structure which achieves the 2nd subject can be used together in a mascara tool, or can be provided separately, respectively. For example, the configuration in which the brush rotates and vibrates with two motors is not limited to the mascara device having the above-described configuration that achieves the first problem, but can also be employed in a mascara device that automatically rotates the conventional brush 20.

As described above, the present invention has a configuration including the bottomed cylindrical mascara storage container, the rod-shaped brush, the support portion of the brush, and the operation unit, so that the operation unit can be reused. It becomes a gentle thing.
In addition, if the bristles rotate and vibrate with two motors, the optimum number of bristles and the optimum frequency can be easily controlled by controlling the number of revolutions of the individual motors without increasing the size. Can get to.

An embodiment is shown in FIGS. 1 to 5. In this embodiment, a bottomed cylindrical mascara storage container 10, a rod-shaped brush 20 inserted into the storage container 10, and a handle 21 of the brush 20 are rotatable. A cylindrical support portion 30 that is supported and coaxially attached to the opening portion 11 of the storage container 10 and a cylindrical operation portion 40 that is coaxially attached to the cylindrical support portion 30. These 10,2 0,3 0,40 is an integral molded product made of each of the synthetic resin, from the viewpoint of environmental protection, it is preferable that the resin is to employ a biodegradable resin.

The storage container 10 stores a liquid mascara b containing fibers, and the properties of the mascara b are set appropriately in terms of the size, amount and viscosity of the fiber in consideration of automatic spin coating.
The brush 20 includes a brush bristle 21 that is curled on a linear body in which a wire at the tip thereof is spirally twisted, and a handle 22 in which an end of the brush bristle 21 is press-fitted and fixed. The amount, length, and density of the eyelashes (brush hairs) 21 are also set appropriately in consideration of automatic rotation application. Further, as shown in FIG. 1, the peripheral surface of the bristles 21 is curved in a concave arc shape (drum shape) so that the peripheral surface follows the shape of the eyelashes, so the mascara b is evenly aligned with the eyelashes a. Can be applied.

A cylindrical rubber packing 12 is fitted into the opening 11 of the container 10 by engaging the annular protrusions 12a on both end faces thereof with the end face or step of the opening 11. The packing 20 suppresses the leakage of the mascara b from the container 10, and when the brush 20 is extracted from the container 10, when the brush hair 21 touches, the mascara b in the brush hair 21 is appropriately scraped off. Make drops.
In addition, when the brush 20 is stored in the container 10, the packing 12 can be brought into contact with the brush handle 22 to reliably prevent the mascara b from leaking out.

The support portion 30 has a partition wall 31 in the middle, and the brush 20 is inserted into the support hole 32 in the center of the partition wall 31 from the brush bristles 21 side (from the right side in FIG. 2B to the left). ), The brush 20 is attached to the support 30. At that time, the protrusion 23 at the end of the handle 22 abuts against the partition wall step portion 31a around the support hole 32 to prevent further insertion. That is, the brush 20 does not come out from the support portion 30 to the container 10 side.
The brush 20 may be attached by inserting the handle 22 into the support hole 32 and then attaching the brush bristles 21 to the handle 22. Alternatively, the handle 22 with the brush bristles 21 may be inserted into the support holes 32. In the latter case, the bristles 21 bend and pass through the support holes 32. A cross-shaped groove 24 is formed on the end surface of the protrusion 23 (see FIG. 4).

The operation unit 40 includes a covered cylindrical cap 41 and a resin tubular member 42 with one end fitted to the cap 41. As shown in FIG. 5, the cylindrical member 42 has a half-cylindrical cylindrical shape, and is provided with a motor 43 in the front part and two control boards 44 in the rear part by fitting. A battery 45 is provided on one control board 44, and a switch 46 is provided on the other control board 44. The pair of halved cylindrical portions may be connected as shown in the figure or may be separated without being connected, but the two are fitted and integrated by the configuration of the projection 42a and its fitting hole 42b and the like. .
The battery 45 is attached by fitting a stopper 47 to the control board 44. For this reason, the battery 45 can be replaced by removing and attaching the stopper 47.

The motor 43 is provided with a cruciform projection 48 on a rotating shaft that protrudes from the center of the end face via a speed reducer 43a. As shown in FIGS. Is fitted and fixed, the cross-shaped projection 48 is located at the center of the other end surface of the cylindrical member 42.
Therefore, when the other end portion of the cylindrical member 42 is fitted into the support portion 30, the projection 48 is fitted into the cross-shaped groove 24 of the brush handle 22 as shown in FIG. The rotational force is transmitted to the brush 20 through the cross-shaped protrusion 48 and the groove 24.

  As shown in FIG. 4, the switch 46 is turned on when the actuator 46a is in a solid line state and all power to the control circuit and the motor 43 is cut off and moved to a one-dot chain line state. For example, when the motor 43 performs forward rotation (right rotation) and is moved to a two-dot chain line state, the motor 43 performs reverse rotation (left rotation). The actuator 46a fits into a knob 49 as shown in FIG. As shown in FIG. 3, the knob 49 is fitted in the sliding guide 41a of the cap 41 and is movable in the guide length direction. By the movement, the actuator 46a is moved to the above-mentioned "stop" and "forward rotation". , Move to “reverse” position. Corresponding to the movement position of the knob 49, a display to that effect is made on the surface of the cap 41. In each figure, reference numeral 42d denotes a substrate support rod.

This embodiment is configured as described above. From the state of FIG. 5, the motor 43, the control board 44, the battery 45, etc. are incorporated into the cylindrical member 42, and as shown in FIGS. One end portion of the cylindrical member 42 is fitted into the cap 41 to form the operation unit 40, and the other end portion of the cylindrical member 42 is fitted into the support portion 30 to which the brush 20 is attached, thereby supporting the support portion 30. The operation unit 40 is attached to the.
The operation part 40 (support part 30) with the brush 20 is inserted into the container 10 from the opening part 11 and the brush 20 is screwed into the opening part 11, thereby obtaining a mascara tool in a non-use state (sales state) (FIG. 2 state).

At the time of use (in mascara), first, as shown in FIG. 1, after holding the gripping part (supporting part 30 and operation part 40) by hand and pulling out the brush 20 from the container 10, with the switch 46, The motor 43 is driven, and the brush 20 is rotated by this driving.
Next, as shown in FIG. 11, the brush 20 in the rotated state is applied to the eyelashes a, and the mascara b is attached onto the eyelashes a along the curling direction of the eyelashes a as well as the conventional manner. Let it curl. Alternatively, after the brush 20 is applied to the eyelash a, the motor 43 is driven to attach and curl the mascara b to the eyelash a.
At this time, depending on the gripped hand, for example, when holding with the right hand, if it is the upper eyelash a, the brush 20 is rotated right (clockwise) toward the tip, and if it is the lower eyelash a, The brush 20 is rotated counterclockwise.

At the time of this mascara, since the brush 20 rotates, the eyelashes a are uniformly wrapped and applied one by one, so that the finish is also beautiful. For this reason, even a beginner or a handicapped person can perform a beautiful mascara. The rotation of the brush 20 may be set as appropriate based on the properties such as the viscosity of the mascara b, and is, for example, 28 to 35 times / minute (rpm).
Further, since the brush 20 vibrates to some extent by driving the motor 43, the application of the mascara b can obtain a sufficient volume and long (maintenance for a long time) effect by applying the vibration to the rotation. The effect can be obtained smoothly.

In order to reliably obtain the vibration of the brush 20, for example, the structure shown in FIG. In this structure, another motor 51 is fixed to the motor 43 on the same axis, and an eccentric vibrator 52 is provided on the rotating shaft of the motor 51. At this time, the motors 43 and 51 and the speed reducer 43a are as small as possible. For example, it is set within the cylindrical member 42 of FIG.
With this configuration, the motor 43 is energized and the motor 51 is energized, and the eccentric vibrator 52 rotates to give vibrations to both the motors 43 and 51 so that the brush 20 vibrates. For this reason, the brush 20 vibrates reliably with rotation and applies the mascara b. At this time, the presence or absence of vibration of the brush 20 may be selected separately from the rotation of the brush 20. For example, a switch for driving (energizing / de-energizing) the vibration motor 51 can be provided separately. The rotation of the motor 51 may be appropriately set based on the properties such as the viscosity of the mascara b, and is set to, for example, 7000 to 8000 times / minute (rpm).

In the above embodiment, the switch 46 is a slide type, but may be a push button type or a rotary (rotation) type. For example, as shown in FIG. 7, instead of the knob 49, a slider 55 is provided that fits on the protrusion 56 of the cylindrical member 42 and is movable in the length direction. It can be a rotary type fitted to the actuator 46a (see FIG. 8).
The cap 41 is, for example, a cylindrical shape shown in the figure and is fitted to the cylindrical member 42 so as to be rotatable around its axis, and the projection 57 of the cap 41 is fitted to the inclined groove 58 of the slider 55 (see FIG. 8). . Therefore, if the cap 41 is rotated left and right around its axis, the actuator 46a of the switch 46 is in the state shown in FIGS. 9 (a), 9 (b) and 9 (c) as described above. Thus, for example, the motor 43 is rotated to the left, stopped, and rotated to the right. The protrusion 57 is in the form of a rod so that it is sunk from the inner surface of the cap 41 (projecting from the surface shown in FIG. 7) when the cap 41 is fitted into the cylindrical member 42, and is fitted into the inclined groove 58 by being pushed in after fitting. (State shown in FIG. 8). The protrusion 57 is fixed to the cap 41 with an adhesive or the like after being fitted into the inclined groove 58.

  When the cap 41 has a cylindrical shape without a lid, the rotation is smooth, but since one end of the cylindrical member 42 is in an open state, one end of the cylindrical member 42 closes one end opening of the cap 41. A closed plate 59 is provided (see FIGS. 7 and 8). Since the cap 41 can be rotated even if it has a lid, the closing plate 59 can be provided on the cap 41 to form a lidded cylindrical cap 41 (see FIG. 2).

  In any of the above embodiments, the battery 45 may be a dry battery, but may be a rechargeable battery or a 100 V charging function may be added to the operation unit 40.

FIG. 8 shows an embodiment in which a vibration mechanism of the brush 20 by the motor 51 and a switch switching mechanism by the rotation of the cap 41 are adopted.
As shown in this embodiment, when the hook pattern 26 is provided on the brush handle 22 and the hook 20 is pressed against the packing 12 when the brush 20 is inserted into the container 10, the packing 12 is temporarily assumed. Even if the mascara b enters and tries to leak through the brush handle 22, the pressure contact prevents the leakage. The protrusion 26 may be any shape as long as it can prevent leakage even if it has a bulge shape or the like, for example. The contact between the protrusion 26 (the bulging portion) and the packing 12 may be a contact pressure that is sufficient to prevent contact and effectively prevent leakage of the mascara b, even if it is not a pressure contact.

As shown in FIG. 10, it is also possible to obtain leakage of the mascara b and smooth rotation of the brush 20 (brush handle 22) through the bearing 27. At this time, when the cylindrical support 30 is attached to the storage container opening 11, the packing 12 is pressed against the bearing 27 so that the mascara b in the storage container 10 does not leak.
Moreover, as shown in the figure, the threaded portion of the support portion 30 into the container 10 can be configured with a cylindrical member 35. The cylindrical member 35 has an internal thread formed on the inner surface thereof that is screwed with the threaded portion of the container opening 11, and the outer surface is a male screw that is threaded with the inner surface of the cylindrical section of the support portion 30 or a spline shape. Fixed to. An adhesive is used as necessary for the fixing. Further, a plurality of cylindrical projections 36 are provided around the side surface of the lid of the cylindrical member 35, and the projections 42e of the cylindrical member 42 of the operation unit 40 are fitted into the projections 36 so that the two 35 and 42 are integrated. It is supposed to be. By this integration, both the cylindrical members 35 and 42 are positioned, that is, the operation unit 40 and the support unit 30 are positioned.
Further, as shown in the figure, a rotary bush 28 may be provided on the operation unit 40 side, and the brush handle 22 may be inserted and fixed to the bush 28. In this case, the rotational force of the motor is transmitted to the bush 28 by the groove 24 and the projection 48. At this time, in the configuration not including the bearing 27 of FIG. 8, when the cylindrical support portion 30 is attached to the storage container opening portion 11, the hook-like projection 26 covers the tip portion of the bush 28.

  As described above, if leakage of the mascara b from the container 10 or the support portion 30 is prevented, there is no possibility that the mascara b enters the operation portion 40, and the rotation of the conventional mascara by entering the rotating portion of the mascara. It will not lead to defects. Moreover, the member which cannot be reused by adhesion of the mascara b becomes the container 10 and the brush 20, which is advantageous for resource saving. At this time, if necessary, the bush 28 and the cylindrical member 35 (including the bearing 27) may be replaced. However, these 28 and 35 are less likely to be attached to the mascara b, and may be used by cleaning. Is expensive.

  Incidentally, the configuration of the vibrations by the separate motor, the hook-like protrusion 26, the bearing 27, the cylindrical member 35, the protrusion 36, and the like is not limited to the above-described embodiments, and the mascara tool for automatically rotating various conventional brushes 20 A mascara tool that is not automatically rotated can be used as appropriate.
