Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a liquid cosmetic applicator, and is applicable to mascara,
This invention relates to a liquid cosmetic applicator that can be widely applied to manicure, eyeliner, eyebrow, eyeshadow, etc.

[Prior art]

A conventional liquid cosmetic applicator consists of a container containing liquid cosmetic and an applicator body that can be inserted into the container, and is used by attaching the cosmetic to the tip of the applicator body. It's summery. Note that when the applicator main body is taken out from the container, the cosmetic material adhering to the tip of the applicator main body is squeezed out by the squeezing part provided at the opening of the container, so that it becomes an appropriate amount.

[Problem that the invention attempts to solve]

However, with conventional liquid cosmetic applicators, when the applicator body is removed from the cosmetic container or when the applicator body is returned to the container after being used, the cosmetic always adheres to the squeezed part, which prevents the application from being applied. The cosmetic also adheres to the shaft of the tool body. When the applicator main body is pulled out and used, there is a problem that the cosmetics adhering to the shaft of the applicator main body may adhere to clothes or skin, which is not desirable.

In addition, liquid cosmetics that adhere to the shaft of the applicator body or the squeezed portion of the container harden and are not used effectively, resulting in the problem of wasted cosmetics.

The present invention was devised in view of the problems of the prior art, and its purpose is to provide a liquid cosmetic applicator in which cosmetics do not adhere to the shaft of the applicator body.

[Means to solve the problem]

In order to achieve the above object, the liquid cosmetic applicator according to the present invention includes a cosmetic supply section that pushes out the contained liquid cosmetic by movement of a built-in piston in the container, and communicates with the cosmetic supply section. and a cosmetic lead-out part into which the tip region of the applicator main body is inserted, and the piston of the cosmetic supply part is moved as necessary to guide the cosmetic to the cosmetic lead-out part. be.

[Effect]

When using the applicator, the piston of the cosmetic supply section is moved to guide the cosmetic to the cosmetic delivery section, so that the cosmetic can be used to the last without wasting it.

Since only the tip region of the applicator main body is taken in and out of the cosmetic outlet portion, liquid cosmetic does not adhere to the shaft portion of the applicator main body.

〔Example〕

Next, an embodiment of the present invention will be described using a mascara applicator as an example.

Figure 1 shows one embodiment of the present invention.
Figure a is a partially cutaway plan view of the mascara applicator with the lid open, Figure 1 b is a plan view thereof, and Figure 1 c is a front view of the mascara applicator with the lid closed. Figure 1 d is its right side view, Figure 1 e

The lid body 6 is assembled so that it can be opened and closed through the lid body 6. container 2
An inner lid 8 is attached to the opening, and a cutout 9
A part of the applicator main body 32 housed in the container 2 is visible through.

As shown in FIG. 1e, the supply section 10 is defined by a rectangular cylinder 12 supported by a cylinder support frame 11a of a frame body 11, a piston 14 built into this cylinder 12, and a piston 14. The mascara solution (hereinafter referred to as
This device is composed of a liquid (referred to as a solution) L and a knock mechanism 16 for moving a piston 14, and is assembled into a frame 11 to form a unit as shown in FIG. 1F.

The cylinder 12 is transparent so that the remaining amount of solution L in the cylinder chamber can be seen. In addition, an opening 11c is formed in the main plate 11b of the frame 11, and the piston 14 is colored in a conspicuous color such as red. It is now possible to confirm that the amount is small. The outer peripheral surface of the piston 14 is made of seal rubber to keep the cylinder chamber in a liquid-tight state, and as the piston 14 moves forward, the solution L is pushed forward from the discharge port 12a. Further, as shown in FIG. 1b, a mirror M is attached to the main plate 11b, so that it can be used without using a separate mirror.

A check washer 15 is provided on the back side of the piston 14 (on the right side in FIG. 1A), and the peripheral edge thereof is brought into contact with the inner circumferential surface of the cylinder. Therefore, the piston 14 can only move forward and cannot move backward. It's becoming like that. Also, there is a rod 17 on the back side of the piston 14.
This rod 17 is supported by a knob member 18 that is assembled to the main plate 11b of the frame 11 so as to be slidable in the front and rear directions.
The knob member 18 has a U-shaped cross section, and its inner circumferential edge is in contact with the outer circumferential surface of the rod 17, and has a groove in the direction in which the piston 14 enters the cylinder 12 (leftward in FIG. 1a). Rods are allowed to move, but
A check washer 19 is provided to prevent the rod from moving in the direction of escape from the cylinder 12 (rightward in FIG. 1a).

Reference numeral 20 denotes a guide that is vertically installed on the main plate 11b and supports the knob member 18, and engages with a protrusion 21 that projects on the outside of the side wall of the knob member, thereby regulating the amount of protrusion of the knob member 18 out of the container. It is also a stopper member. The reference numeral 18a designates a knock head, and a part of the side wall of the container with which the knock head 18a engages is cut out, and the knock head 18a protrudes into the cutout 2a.
The tip of 8a is substantially flush with the surface of the side wall of the container. Reference numeral 22 denotes a return spring (plate spring) provided on the knock member 18, which comes into contact with a protrusion 24 protruding from the main plate 11b, and returns the knob head 18a.

The inside of the cylinder 12 communicates with a brush insertion section 30 which is a solution outlet section via a bypass 26, and the solution L pushed out by the piston 14 is guided to the brush insertion section 30.

A bellows part 100 is provided in the middle of the bypass 26, and this bellows part 100 is a pressure adjusting member supported by a compression spring 102. That is, the solution L pushed out from the cylinder 12 is not all pushed out to the brush insertion part 30, but a part of it is temporarily stored in this bellows part 100, and is transferred to the brush 32d.
When the brush is pulled out from the brush insertion section 30, it is delivered to the brush insertion section 30. In this embodiment, the spring constant of the compression spring 102 is set such that approximately half of the solution L pushed out from the cylinder 12 by the knock action of the knock head 18a is guided to the bellows part 100 and the remaining half to the brush insertion part 30. And the volume of the bellows portion 100 is adjusted.

The applicator main body 32 is located inside the brush insertion portion 30.
A brush 32a is inserted. Applicator body 3
2 is composed of a brush 32a to which the solution L is attached, a brush shaft portion 32b, and a handle 32c which is a knob, and a housing recess 31 is formed in the container 2 to accommodate this applicator body 32. . The housing recess 31 has a cutout in the side wall region of the container 2 as shown by reference numerals 3a and 3b, and the cutouts 3a and 3b are connected to the cutout 9 of the inner lid 8, and the opening region 9 , 3a, 3b and pick the handle 32c, from which the applicator main body 32 can be taken in and out as shown by the arrows in FIG. 1B.

Further, on the open end side of the brush insertion section 30, a squeezing rubber 34 whose inner peripheral edge is press-fitted to the brush shaft section 32b is provided. When removing the brush 32a from the section 30, the brush 3
2a is squeezed to optimize the amount of the attached solution L.

Note that reference numeral 6a is a hook protruding from the lid 6, and reference numeral 3c is an engaging portion that engages with the hook 6a protruding from the container, which is an opening/closing lock mechanism for the lid 6.

Next, the procedure for using this mascara applicator will be explained.

First, even if the engagement between the hook 6a and the engaging portion 3c is released, the lid 6 may be opened or the lid 6 may be left closed, but when the knob head 18a is pressed with a finger, the rod 17 is integrated with the knob member 18. The piston 14 moves forward and pushes out the solution L from the discharge port 12a. Then, when you stop pressing your finger, Rod 17
is movable to the left with respect to the check washer 19. In other words, the check washer 19 is movable to the right with respect to the rod 17, and the knob member 18 is returned to its original position by the action of the return spring 22. Return. At this time, the piston 14 is maintained in this advanced position by the action of the check washer 15. Then, the solution L pushed out from the cylinder 12 is guided to the brush insertion part 30 through the bypass 26, and the brush 32a
Attach to. Also, at this time, a part of the solution L pushed out from the cylinder 12 enters the bellows part 100 and resists the biasing force of the compression spring 102.
Inflate 0. When the applicator main body 32 is pulled out from the brush insertion section 30, the brush insertion section 30
communicates with the atmosphere, the pressure balance within the brush insertion section 30 is disrupted, and the solution L is further guided into the brush insertion section 30.

Note that if the solution L introduced into the brush insertion part 30 by one knock is insufficient, by knocking two or three times, the piston 14 will move forward as shown by the arrow in FIG. A proportional amount of solution L is introduced into the brush insert 30.

When the solution L introduced into the brush insertion portion 30 adheres to the brush 32a, the applicator main body 32 is pulled out to the right in FIG. 1b by holding the handle 32c and used. After using the applicator body 32, the applicator body 32 is inserted back into its original position.

The opening for putting in and taking out the applicator body 32 is as follows.
The large cutout prevents the brush 32a from coming into contact with the periphery of the opening when the applicator main body 32 is taken in and out. Also, the brush 3 of the applicator body 32
Brush insertion part 30 where only part 2a is a solution outlet part
Since it is used by being put in and taken out, there is no risk of the solution L adhering to the shaft portion 32b, and therefore there is no problem such as staining hands or clothes with the solution.

Further, since the solution L in the cylinder 12 is guided into the brush insertion part 30 in a small space, the solution L can be used without wasting it.

Furthermore, by making the unit shown in FIG. 1f replaceable, it is only necessary to replace some of the units in the cosmetic applicator, and the cost becomes correspondingly cheaper.

FIG. 2 shows the main structure of a second embodiment of the present invention, with FIG. 2a being a cross-sectional view before the lock is clicked, and FIG. 2b is a cross-sectional view when the lock is locked.

In these figures, reference numeral 42 is a cylinder containing the solution L, and a piston 44 that can only move forward is housed inside. A knob member 48 is assembled to one end of the cylinder 42. code 4
5 is a check washer, 46 is a coil spring for returning the knob member, and 49 is a check washer that only allows the rod 47 to move forward. The rest is the same as the previous embodiment, and the explanation thereof will be omitted by giving the same reference numerals.

Then, use your finger to touch the knob head 48 of the knob member 48.
When a is clicked, the knock member 48 and the piston 4
4 move forward together, and from the state shown in Figure 2 a to the second
The state shown in Figure b is reached. The solution L pushed out by the piston 44 causes the bellows portion 100 to swell, and a portion thereof is guided to the brush insertion portion 30 through the bypass 26. Knock head 4
When released from 8a, the return spring 46 acts to return the knob member 48 to its original position. At this time,
Piston 44 is retained in this advanced position by check washer 45. When the button is clicked two or three times, the piston 44 moves forward in sequence as shown by the arrows in FIG. Note that the reference numeral 48 is a guide for the rod 47.

FIG. 3 shows the main structure of a third embodiment of the present invention, with FIG. 3a being a cross-sectional view before the lock is clicked, and FIG. 3b is a cross-sectional view when the lock is locked.

In this example, the cylinder 5 containing the solution L is
A piston 54 that can only move forward is housed within the cylinder 52, and a knock head 53 is located at the end of the cylinder 52.
is formed. That is, the cylinder 52 is provided with a function as a knock member, and the structure is simple and compact. Reference numeral 55 is a non-return washer which is used to move the piston 54 forward together with the cylinder 52 by the notch of the notch head 53. Further, reference numeral 53a is an air hole.

Further, the cylinder 52 is directly connected to the brush insertion portion 30 via the bypass 26, and the cylinder 52 is directly connected to the brush insertion portion 30 via the bypass 26.
A bellows portion 100 is provided at the front end of the bellows. Therefore, by the knocking operation of the knocking head 53, all of the solution L pushed out from the cylinder 52 is guided to the brush insertion portion 30. And Figure 3b
In the knocked state shown in the figure, the return spring 46
acts, and the cylinder 52 attempts to return to its original position. When you release your finger from the head 53, the cylinder 52 returns to its original position, but the bypass 26
Since the diameter of the piston 54 is small and the nokhead side of the piston 54 is at atmospheric pressure, the cylinder 52 is quickly returned to its original position, so a negative pressure acts inside the cylinder 52, causing the piston 54 to move back slightly. , it does not return to its original position, and as a result it stops at a position moved forward from its original position. Furthermore, at this time,
The air inside the brush insertion part 30 is pushed by the solution L led from the bypass 26 to swell the bellows part 100, and when the applicator main body 32 is extracted from the brush insertion part 30, the air is released from the opening of the squeezing rubber 34 to the outside. run away to

The rest is the same as the first embodiment, and the explanation thereof will be omitted by giving the same reference numerals.

FIG. 4 is a sectional view showing the main structure of the fourth embodiment of the present invention, in which a threaded rod 66 with a left-handed thread is inserted into the cylinder 62, and this threaded rod is also inserted into the cylinder 62. Piston 64 screwed with 66
is located. A seal rubber is provided around the outer peripheral surface of the piston 64 to keep the inside of the cylinder chamber in a liquid-tight state. Reference numeral 68 denotes a rotary knob assembled to the end of the threaded rod via a ratchet mechanism 69, which transmits rotational force in the clockwise direction but rotates idly in the counterclockwise direction. When the knob 68 is turned clockwise, the threaded rod 66 also rotates, and the piston 64 moves forward by an amount proportional to the amount of rotation of the knob 68. In this embodiment, the frictional force between the inner peripheral surfaces of the piston 64 and the cylinder 62 is increased by the rotation of the threaded rod 66.
In other words, the rotation of the threaded rod 66 prevents the piston 64 from rotating together with the threaded rod 66; A guide member that engages with the piston 64 may extend in the inner axial direction of the cylinder 62 to prevent the piston 64 from rotating.

FIG. 5 shows a fifth embodiment of the present invention.

In this embodiment, the cylinder 73 and the brush insertion portion 30 are formed directly on the container 72, and the applicator main body 80 is provided with a function as a knob member.

Inside the container 72, there is a pump 76 and a squeezing rubber 77.
and a pusher 78 are sequentially inserted and arranged.
A brush insertion portion 30 is formed within the pump 76, and a solution reservoir chamber 82 is formed adjacent to the pump 76. This solution reservoir chamber 82 is a passage 82a.

Next, the procedure for using the mascara applicator of this fifth embodiment will be explained.

The handle 80 of the applicator body which is the knob head
When c is clicked in the direction of the arrow, the pump 76 moves forward and the solution L in the reservoir chamber 82 flows into the pump communication groove 76a.
It is guided into the brush insertion part 30 through. At this time, the air in this brush insertion part 30 is pushed out from the passage 84 to the bellows part 100, causing the bellows part 100 to bulge. And the handle 8 which is the knob head
When the pressure 0c is stopped, the applicator main body 80, which is a knock member, returns to its original position due to the action of the return spring 86. However, since the passage 76a has a small diameter and the return speed of the knock member is fast, negative pressure acts within the solution reservoir chamber 82. Therefore, the solution L is guided into the solution reservoir chamber 82 from within the cylinder 73 communicating with the solution reservoir chamber 82 , and the solution L is introduced into the solution reservoir chamber 82 .
The piston 74 advances to a position where the pressure inside the cylinder 73 is the same as that of the cylinder 73. When the applicator main body 80 is pulled out, the air inside the bellows part 100 is squeezed out from the rubber 7.

Note that 75 is a check washer, 72a is an air hole, 80a and 80b are brushes of the applicator body,
This is the shaft. The rest is the same as the above example,
By assigning the same reference numerals, the explanation thereof will be omitted.

FIG. 6 shows a sixth embodiment of the present invention.

In the first to fifth embodiments described above, the cylinder containing the solution L and the brush insertion part are arranged in parallel, but in this embodiment, the cylinder and the brush insertion part are arranged in series. It is distinctive in that it is placed in

Reference numeral 92 is a cylinder, which houses a piston 74.
is capable of moving only forward (movement in the direction of the arrow) and is threadedly connected to the knob member accommodating portion 94. In addition, the code|symbol 95 is a screw connection part.

A pump 9 is provided in this knob member accommodating portion 94.
6, a squeezing rubber 77 and a pusher 78 are inserted and arranged in order. Inside the pump 96, there is a solution reservoir chamber 8.
A brush insertion portion 30 is formed which communicates with the inside of the cylinder 92 via 2. Further, the solution reservoir chamber 82 and the brush insertion portion 30 communicate with each other through a small diameter passage 96a. This brush insertion portion 30 communicates with a pressure relief chamber 104 on the outer periphery of the pump 96 via a passage 103. A balance piston 97 is attached to the outer periphery of the pump 96 and is slidable in an airtight manner within the knock member accommodating portion 94, and a coil spring 97a is interposed on one side of the balance piston 97. Note that 92b and 94a are air holes, 98 is an O-ring, and 97b is a stopper protruding from the other surface of the balance piston 97. The rest is the same as the fifth embodiment, and the explanation thereof will be omitted by giving the same reference numerals.

Next, the procedure for using the applicator of this example will be explained.

When the handle 80c, which is the knock head, is pushed in, the pump 96 moves forward, and the solution L in the solution reservoir chamber 82 is guided into the brush insertion part 30 through the passage 96a. On the other hand, the air in the brush insertion part 30 is driven from the passage 103 to the pressure relief chamber 104, presses the balance coil spring 97a, and moves the balance piston 97 to the left in FIG. When the knock of the knock head 80c is closed, the pump 96 returns to its original position by the action of the return spring 86. At this time, because the passage 96a has a small diameter, negative pressure acts within the solution reservoir chamber 82, and this solution reservoir chamber 82
The inside of the cylinder 92, which communicates with the cylinder 92 through the passage 92a, also becomes negative pressure. Therefore, the piston 74 moves to a position where the pressure is balanced, as indicated by the arrow in FIG.

In addition, in the first to sixth embodiments described above, the present invention has been explained using a mascara applicator as an example, but the application of the present invention is not limited to a mascara applicator, but can also be applied to a manicure applicator. Needless to say, it can be widely used as a liquid cosmetic applicator for eyeliners, eyebrows, eye shadows, and the like.

[Effect of idea]

As is clear from the above description, according to the liquid cosmetic applicator according to the present invention, the piston of the cosmetic supply section is moved to insert the cosmetic in the supply section into the tip region of the applicator main body. Since the cosmetic is guided to the cosmetic outlet, the cosmetic can be used to the end without wasting it.

Since only the tip region of the applicator body is taken in and out of the cosmetic delivery part where the cosmetic is guided, the cosmetic does not adhere to the shaft of the applicator body, and therefore the cosmetics do not stick to the hands or clothes. There is no risk of contaminating it.
