Description

The present invention relates to a double eyelid forming device that forms a double eyelid on the eyelid, for example, to artificially change a single eyelid into a double eyelid.

Conventionally, there is known a double eyelid forming device that forms a double eyelid by artificially creating wrinkles in the left-right direction slightly above the edge of the upper eyelid.

An example of this type of double eyelid forming instrument is an ophthalmic bougie, which is a medical instrument used for forming tear ducts, but because it is rigid and has a thin tip, it can also be used to form a double eyelid by pressing the tip against the eyelid.
As an ophthalmic bougie, for example, the one described in Patent Document 1 is known.

Typically, when using a bougie as a double eyelid forming device, two bougies are used. For example, the desired wrinkles are created by pressing the tips of the two bougies against the eyelid with a space between them and widening the distance between the two tips. The temporary wrinkles are then fixed with adhesive to form a double eyelid.

However, a double eyelid forming device consisting of two bougies must be operated by holding each bougie with both hands. Therefore, if you try to create wrinkles on your eyelids yourself, a great deal of dexterity is required, and it is not always easy to create wrinkles. For example, it is difficult to create wrinkles while holding a hand mirror, and it is also difficult to move each hand in the appropriate direction while looking at the reversed images of yourself reflected in the mirror in front of you.

In response to this, there is a demand for a double eyelid forming device that can be used with one hand so that people can relatively easily create the above-mentioned eyelid creases on their own. However, it cannot be said that sufficient research has been done on a double eyelid forming device that can be operated with one hand to create double eyelid creases.

Therefore, the objective of the present invention is to provide a double eyelid forming device that allows the user to create double eyelid creases using only one hand.

The double eyelid forming device according to the present invention is a double eyelid forming device for forming double eyelids by creating wrinkles in the left-right direction on an eyelid,
The device comprises two elongated base members arranged parallel to each other, and a connecting member connecting the two base members,
The base material has, on one side and the other side in a longitudinal direction, a contact portion that is brought into contact with an eyelid and an operation portion that receives a finger force for moving the base material,
The contact portions of the two base materials are adjacent to each other, and the operation portions of the two base materials are adjacent to each other,
The present invention is characterized in that, by using the principle of leverage, at least a part of the connecting member serves as a fulcrum, and by moving the operating parts closer to each other, the abutment parts move farther apart from each other.

According to the double eyelid forming device having the above configuration, the contact parts can be moved away from each other by applying force from the fingers to each of the two operating parts and moving the operating parts closer to each other. By increasing the distance between the two contact parts while pressing them against the eyelid, wrinkles for forming a double eyelid can be created between the two contact parts while pulling the skin of the eyelid. Since force can be applied to each contact part from, for example, the thumb and index finger, the above double eyelid forming device can be used with one hand.
In this way, with the above-mentioned double eyelid forming device, double eyelids can be formed even with one hand.

In the above double eyelid forming device, the connecting member has two plate-shaped bodies overlapping each other in a thickness direction between the two base materials,
The two plate-like bodies are bonded to one of the base materials and the other of the base materials,
the connecting member has an engaging portion that engages the two plate-like bodies in an overlapping state,
the engaging portion is configured to relatively rotate the two plate-like bodies about a rotation axis extending in a thickness direction of the plate-like bodies,
The rotation axis may serve as the fulcrum, and the contact portions may be configured to move farther apart by moving the operation portions closer to each other.
With this configuration, the two plate-shaped bodies are engaged in an overlapping state at the pivot point that serves as the fulcrum of the lever principle, so that the two plate-shaped bodies can rotate relative to each other in an overlapping state. Therefore, the rotation of the two plate-shaped bodies becomes a stable movement, and the stable rotation is transmitted to each substrate joined to each plate-shaped body. Since the stable rotation is transmitted to each substrate, the movement of the abutting portions of the two substrates moving away from each other is stable. Therefore, double eyelid wrinkles can be created more easily.

In the above double eyelid forming device, the connecting member has a rod-shaped elastic body,
one side and the other side in the longitudinal direction of the rod-shaped elastic body are joined to one of the base materials and the other of the base materials, respectively;
A part of the rod-shaped elastic body arranged between the two base materials may serve as the fulcrum, and the abutment portions may be configured to move further apart by moving the operating portions closer to each other.
With this configuration, the elasticity of the rod-shaped elastic body, which serves as the fulcrum of the leverage principle, allows the operating parts to approach each other so that the abutting parts separate, and then the force applied to the operating parts is released, allowing the double eyelid formation device to return to its original state before the force was applied.As a result, there is no need to manually return the double eyelid formation device to its original state each time a wrinkle is created, making it easier to handle the double eyelid formation device.

The double eyelid forming device further includes two protruding members protruding from each substrate toward the adjacent substrate,
The protruding members are arranged so as to be able to abut against each other,
The contact portions of the protruding members may serve as the fulcrum, and the contact portions may be configured to move further apart by moving the operating portions closer to each other.
With this configuration, the principle of leverage can be utilized more reliably, so that the operation of moving the operating portions closer to each other to move the contact portions away from each other can be performed more reliably.

The double eyelid formation device described above may further include fixing members attached to the operating parts for fixing fingers therein.
With this configuration, for example, a force can be applied to the operating parts to bring them closer together while the thumb and index finger are fixed to the fixing member, so that the force of the fingers can be stably applied to the operating parts, making it easier to operate the double eyelid forming device and more convenient to create double eyelid creases.

In the above double eyelid forming device, each tip portion of the abutment portion may be curved toward the adjacent base material.
With this configuration, when the contact parts are separated by applying force to the operating part as described above, the tip part can be moved in a direction substantially opposite to the direction in which the tip of the tip part faces while being pressed against the eyelid. This makes it possible to prevent the tip of the tip part from getting caught on the eyelid. Therefore, it is possible to more easily create double eyelid wrinkles.

The double eyelid forming device of the present invention allows you to create double eyelid creases with just one hand.

FIG. 13 is a perspective view of a double eyelid forming device according to another embodiment (third embodiment).

One embodiment (first embodiment) of the double eyelid forming device according to the present invention is described below.

The eyelid that is treated with the above-mentioned double eyelid forming device 1 is usually the upper eyelid. The above-mentioned double eyelid forming device 1 may be used to create wrinkles on the upper eyelid to form a double eyelid, or may be used to create wrinkles on the lower eyelid (for example, a tear trough). In this specification, creating a tear trough on the lower eyelid is also referred to as forming a double eyelid.
Hereinafter, the double eyelid forming device 1 of this embodiment will be described in detail, taking as an example a case in which a double eyelid is formed by creating a wrinkle slightly above the edge of the upper eyelid.

As shown in FIGS. 1 to 5, the double eyelid forming device 1 of this embodiment is a double eyelid forming device 1 for forming a double eyelid by, for example, creating a wrinkle S in the left-right direction on an upper eyelid M,
The device comprises two elongated base members 10 arranged parallel to each other, and a connecting member 20 connecting the two base members 10,
The base material 10 has, on one side and the other side in a longitudinal direction, a contact portion 12 to be brought into contact with an eyelid and an operation portion 11 to receive a finger force for moving the base material 10,
The contact portions of the two base members 10 are adjacent to each other, and the operation portions of the two base members 10 are adjacent to each other.
Using the principle of leverage, at least a part of the connecting member 20 serves as a fulcrum, and as the operating portions 11 approach each other, the abutting portions 12 move further away from each other.

The fulcrum is located between the operating parts 11 and the contact parts 12 in the longitudinal direction of the base material 10. The fulcrum is located between the two base materials 10. When using the double eyelid formation device 1, the two operating parts 11 that receive the force of the fingers become the force points in the principle of leverage. The two contact parts 12 that come into contact with the eyelids become the points of action in the principle of leverage. Because the double eyelid formation device 1 has the above-mentioned configuration, the contact parts 12 can be moved away from each other by moving the operating parts 11 closer to each other. Note that in this specification, it does not matter which force acts on the operating parts 11 or the contact parts 12 is larger.

As shown in Figures 1 to 5, the double eyelid forming device 1 of this embodiment further includes fixing members 30 attached to the operating parts 11 for fixing the fingers.

In the double eyelid formation device 1 of the present embodiment, the connecting member 20 has two plate-like bodies 21 overlapping each other in the thickness direction between the two base materials 10,
The two plate-like bodies 21 are bonded to one base material 10 and the other base material 10,
The connecting member 20 has an engaging portion 22 that engages the two plate-like bodies 21 in an overlapping state,
The engagement portion 22 is configured to allow the two plate-like bodies 21 to rotate relatively around a rotation axis extending in the thickness direction of the plate-like bodies 21.
The rotation axis serves as a fulcrum, and as the operation portions 11 are brought closer to each other, the abutment portions 12 are configured to move farther apart from each other.

With this configuration, the two plate-like bodies 21 are engaged in an overlapping state at the pivot point that serves as the fulcrum of the lever principle, and so the two plate-like bodies can rotate relative to one another while overlapping. This results in stable rotation of the two plate-like bodies, which is then transmitted to each of the substrates joined to each plate-like body. As stable rotation is transmitted to each substrate, the movement of the contacting portions of the two substrates moving away from each other is stable. This makes it easier to create double eyelid creases.

The eyelids before treatment with the above-mentioned double eyelid forming device 1 are usually single eyelids, but the above-mentioned double eyelid forming device 1 may be used on double eyelids to change the appearance of existing double eyelids.

The practitioner who uses the double eyelid formation device 1 is not particularly limited. For example, the double eyelid formation device 1 may be used to perform a treatment on one's own eyelids, or on the eyelids of another person. In other words, the person being treated may be the practitioner using the double eyelid formation device 1, or may be a different person. However, since the double eyelid formation device 1 can be used with one hand, it is suitable for use in forming double eyelids on one's own eyelids.

The double eyelid formation device 1 is preferably large enough so as not to obstruct the view of the patient in front of the eyes. The relatively small size of the double eyelid formation device 1 has the advantage that it is easy to operate while looking in a mirror, for example, when forming a double eyelid on one's own eyelid.

The substrate 10, the fixing member 30, and the plate-like body 21 are formed of, for example, a resin material (plastic material), a rubber material, a wood material, etc. Examples of resin materials include polyolefin resin materials such as polyethylene and polypropylene, polyester resin materials such as polyethylene terephthalate, polyamide resin materials such as polyamide 66, acrylic resin materials, and ABS resin (styrene/acrylonitrile/butadiene copolymer) materials.

The substrate 10 may be, for example, a long, thin plate. The tip of the contact portion 12 of the long, thin plate-shaped substrate 10 is in the shape of a long, thin rod so as to be in contact with the eyelid.

The longitudinal length of the elongated plate-like substrate 10 may be, for example, 30 mm or more and 100 mm or less. The width of the elongated plate-like substrate 10 may be, for example, 3 mm or more and 20 mm or less. If the width varies partially, it is preferable that the length of the widest part is the above value. The thickness of the elongated plate-like substrate 10 may be, for example, 0.5 mm or more and 4.0 mm or less. If the thickness varies partially, it is preferable that the thickness of the thickest part is the above thickness.

In this embodiment, the two base materials 10 are both elongated plate-like as shown in Figures 1 to 3. The two base materials 10 are arranged so that one surface of each of them faces each other. The operation portions of the two base materials 10 are arranged adjacent to each other, and the abutment portions are arranged adjacent to each other. The tip portions of the abutment portions 12 are also arranged adjacent to each other.
When the double eyelid formation device 1 is viewed from the front to the back of the person to be treated, immediately before the contact portion 12 comes into contact with the eyelid during use, the two base materials 10 are positioned so as to be, for example, parallel to each other.
Since the two base materials 10 are arranged with a gap between them, the distance ensures a certain degree of visibility for the patient. Therefore, when forming double eyelids by oneself, the patient can perform the treatment while looking in a mirror. Therefore, it is relatively easy to form double eyelids by oneself.

The tip portions of the contact portions 12 of the substrate 10 are preferably curved. In this embodiment, the tip portions of the contact portions 12 are curved toward the adjacent substrate 10. Preferably, the tip portions are curved so that they approach the adjacent substrate 10 as they approach the tip. In addition, the tip portions of the contact portions 12 are preferably curved so that the tip direction faces the eyelid during use. For example, when the two contact portions 12 are pressed against the eyelid, the direction in which the tip of each contact portion 12 faces is a part of the eyeball behind the eyelid.
With this configuration, when the contact parts 12 are moved farther apart by applying force to the operating part 11 as described above, the tip part can be pressed against the eyelid and moved in a direction substantially opposite to the direction in which the tip of the tip part faces. This makes it possible to create wrinkles along the curve of the edge of the eyelid, forming a natural double eyelid.

The tip portion of the abutment portion 12 may be curved, for example, so that the radius of curvature is 1.0 mm or more and 10.0 mm or less, or 2.0 mm or more and 6.0 mm or less.

The double eyelid forming device 1 described above is configured such that, when in use, the tip portions of the contact portions 12 of the two substrates 10 are pressed against the upper eyelid, causing each tip portion to bite into the eyelid. The two substrates 10 have sufficient rigidity to maintain a rod shape when each tip portion is pressed against the eyelid. Furthermore, as shown in FIG. 4, the distance between the tip portions is increased by moving the operating portion 11 closer to each other as described above and separating the contact portions. At this time, wrinkles can be created between the two tip portions by pulling the skin of the eyelid. The wrinkles created temporarily in this way can be fixed with adhesive applied to the eyelid to form a double eyelid.

By creating wrinkles by pulling the skin of the eyelid as described above, wrinkles can be created more reliably than when the wrinkles are created by simply inserting the bougie or the like. Specifically, by creating wrinkles while pulling the skin of the eyelid so that the tip parts of the two contact parts 12 are moved away from each other, the skin in contact with the tip parts, i.e., the skin at both ends of the wrinkle, is pulled left and right. This applies tension to the skin in the length direction of the wrinkle, making it possible to create deeper wrinkles. In addition, wrinkles can be created between the two tip parts from one tip part to the other tip part. Therefore, wrinkles can be created reliably between the two tip parts. Furthermore, by creating wrinkles in this way, the wrinkled state can be maintained for a while even if the tip parts of the contact parts 12 are moved away from the eyelid. In this respect, wrinkles can also be created reliably.

In the above-mentioned double eyelid forming device 1, when the two substrates 10 are parallel as shown in FIG. 2, the distance (length) between the two substrates 10 may be 5 mm or more and 30 mm or less. Such a distance is preferably 7.5 mm or more, and more preferably 25 mm or more. Such a distance is preferably 10 mm or less, and more preferably 20 mm or less.

The cross-sectional shape of the operating section 11 of each substrate 10 cut perpendicularly to the longitudinal direction of the substrate 10 is not particularly limited. Such a cross-sectional shape may be an elongated ellipse, or a polygon such as a hexagon, rectangle, or triangle. The corners of the polygonal cross section may be rounded. In addition, a protrusion or depression may be formed on the surface of each substrate 10 along the longitudinal direction.

For example, as shown in FIG. 5, the double eyelid formation device 1 is configured such that, during use, the contact portion 12 is positioned above the operating portion 11 and the tip portion of the contact portion 12 is pressed against the upper eyelid M.
The two tip portions, which are separated from each other immediately before use, are arranged, for example, so that each tip direction faces the upper eyelid M and faces the central portion in the left-right direction of the upper eyelid M. In addition, the two tip portions are arranged with a distance between them that is shorter than the length of the wrinkles S to be made in the upper eyelid M.
When the distance between the contact portions 12 is increased by bringing the operating portions 11 closer to each other as described above, wrinkles S can be formed between the two tip portions as shown in Fig. 5. Therefore, wrinkles S can be created without pressing the tip portions against all of the wrinkles S to be created. This makes it possible to reduce the contact area with the skin when creating wrinkles S. Therefore, when forming a double eyelid by a method in which the skin of the upper and lower eyelids is glued together with an adhesive across the wrinkles S, the smaller contact area with the skin reduces adhesion interference with the skin.

The cross-sectional shape of the contact portion 12 of each substrate 10 cut perpendicularly to the longitudinal direction of the substrate 10 is not particularly limited. Such a cross-sectional shape may be a perfect circle, an ellipse, or a polygon such as a rectangle or a triangle. The corners of the polygonal cross section may be rounded.

It is preferable that the tip of the contact portion 12 is rounded. This helps prevent pain in the eyelid when the tip is pressed against the eyelid.

In this embodiment, the double eyelid forming device includes a connecting member 20 that is disposed between two substrates 10 and connects adjacent substrates. The connecting member 20 has two plate-like bodies 21 that overlap each other in the thickness direction between the two substrates 10, and an engaging portion 22 that engages the overlapping plate-like bodies. One plate-like body 21 is joined to one substrate 10, and the other plate-like body 21 is joined to the other substrate 10. The engaging portion 22 is configured to allow the two plate-like bodies 21 to rotate relatively around a rotation axis that extends in the thickness direction of the two plate-like bodies 21.

In this embodiment, the connecting member 20 is disposed between two adjacent substrates 10. The connecting member 20 is also disposed between the contact portion 12 and the operating portion 11 in the longitudinal direction of each substrate 10. More specifically, the connecting member 20 is disposed closer to the operating portion than the central portion of the two substrates 10 in the longitudinal direction.

Each plate-like body 21 is joined to one of the substrates 10. For example, as shown in FIG. 2, a part of the end face of the plate-like body 21 is joined to a part of one surface of the plate-like portion of the substrate 10. In other words, one plate-like body 21 extends from a part of the inner surface of one substrate 10 toward the other substrate 10 with said direction as its surface direction, and the other plate-like body 21 extends from a part of the inner surface of the other substrate 10 toward the one substrate 10 with said direction as its surface direction.

The thickness direction of the two overlapping plate-like bodies 21 is perpendicular to the direction in which the two substrates 10 face each other, and perpendicular to the longitudinal direction of the two substrates 10. Therefore, the above-mentioned rotation axis direction is perpendicular to both the direction in which the two substrates 10 face each other and the longitudinal direction of the two substrates 10. Therefore, the above-mentioned double eyelid forming device is configured so that one plate-like body 21 and one substrate 10 joined to the plate-like body 21, and the other plate-like body 21 and the other substrate 10 joined to the plate-like body 21 can rotate in the opposite directions relative to each other around the rotation axis of the engagement part 22, so that the operating parts can be moved closer to each other or farther away from each other. Similarly, it is configured so that the abutting parts can be moved closer to each other or farther away from each other. In this embodiment, the two substrates 10 move around the rotation axis so as to follow the imaginary plane formed between the two adjacent substrates 10.

The plate-shaped body 21 is made of, for example, resin. It is preferable that the material of the plate-shaped body 21 is the same as the material of the base material 10.

The engagement portion 22 has, for example, a hinge mechanism, and is configured so that the two plate-like bodies 21 can be rotated relatively around a rotation axis that passes through the two overlapping plate-like bodies 21 in the thickness direction by the hinge mechanism.
Specifically, the engagement portion 22 has a cylindrical pin member arranged in a through hole that penetrates the two overlapping plate-like bodies 21 in the thickness direction, and the pin member is arranged so that the cylindrical axis direction of the pin member is the penetrating direction of the through hole, thereby forming a hinge mechanism in which the cylindrical axis of the pin member serves as the above-mentioned rotation axis.
Since the two plate-like bodies 21 are respectively joined to one base material 10 and the other base material 10, the double eyelid formation device is configured so that the two base materials 10 can rotate about the rotation axis. As a result, the double eyelid formation device is configured so that, by using the principle of leverage, the engagement portion 22 of the connecting member 20 serves as a fulcrum, and by moving the operation portions 11 closer to each other, the abutment portions 12 move further apart from each other.

In this embodiment, the double eyelid forming device has a fixing member 30 for stably applying force from a finger to the operating part 11 of the base material 10. The fixing member is attached to the operating part 11 of the base material 10. The fixing member 30 has an annular body 31, for example, as shown in FIG. 1.

The ring-shaped body 31 of the fixing member 30 has, for example, a shape with a part of a ring missing. In other words, the ring-shaped body 31 has, for example, a shape in which one end of a linear member arranged to draw a ring is joined to the operating unit 11 and the other end is separated from the one end. The surface direction of the imaginary circle drawn by the ring-shaped body 31 and the extension direction of the base material 10 to which the ring-shaped body 31 is joined are, for example, perpendicular.

The fixing member 30 is configured so that a finger can be inserted into the inner space of the ring-shaped body 31 and fixed in the inner space of the ring-shaped body 31. The two fixing members 30 are configured so that, for example, one can fix an index finger and the other can fix a thumb. Since the ring-shaped body 31 has a shape in which a part of the ring is missing, even if the thickness of the finger inserted in the inner space of the ring-shaped body 31 is larger than the diameter of the ring-shaped body 31, the two ends of the ring-shaped body 31 can be spaced apart from each other, so that the finger can be inserted into the inner space while expanding the diameter of the ring-shaped body 31. Therefore, the initial diameter of the ring-shaped body 31 may be smaller than the thickness of the thumb, for example.

The above-mentioned double eyelid forming device 1 is configured so that finger force can be applied to each of the operating parts 11 of the two base materials 10 by two fingers fixed respectively by two fixing members 30. In other words, it is configured so that finger force can be transmitted to each of the operating parts 11 via each fixing member 30. The above-mentioned double eyelid forming device 1 is configured so that the contact parts 12 are moved further apart by bringing the operating parts 11 closer to each other by the force of the two fingers. Note that force may also be applied directly to the operating parts 11 by the fingers fixed by the two fixing members 30.

The fixing member 30 is made of, for example, resin. It is preferable that the material of the fixing member 30 is the same as the material of the base material 10.

Next, the double eyelid formation device 1' of another embodiment (second embodiment) will be described below.

In detail, the double eyelid forming device 1′ of another embodiment (second embodiment) is as shown in FIGS. 6 to 8,
A double eyelid forming device for forming double eyelids by creating wrinkles in the left-right direction on an eyelid,
The device comprises two elongated base members 10 arranged parallel to each other, and a connecting member 20 connecting the two base members 10,
The base material 10 has, on one side and the other side in the longitudinal direction, a contact portion 12 that is brought into contact with the eyelid and an operation portion 11 that receives a finger force for moving the base material 10,
The contact portions of the two base members 10 are adjacent to each other, and the operation portions are adjacent to each other.
Using the principle of leverage, at least a portion of the connecting member 20 serves as a fulcrum, and as the operating portions 11 are brought closer to each other, the abutting portions 12 are configured to move further away from each other.

In addition, in the double eyelid formation device 1′ of another embodiment (second embodiment), the connecting member 20 has a rod-shaped elastic body 25,
One side and the other side in the longitudinal direction of the rod-shaped elastic body 25 are joined to one base material 10 and the other base material 10, respectively.
A part of the rod-shaped elastic body 25 arranged between the two base members 10 serves as a fulcrum, and by using the principle of leverage, the contact portions 12 are configured to move further apart by moving the operating portions 11 closer to each other.

The double eyelid forming device 1′ of another embodiment (second embodiment) further includes two protruding members 40 protruding from each base material 10 toward the adjacent base material 10 (the facing base material),
The protruding members are arranged so as to be able to abut against each other,
The contact portions of the protruding members serve as fulcrums, and by moving the operating portions 11 closer to each other, the contact portions 12 move further away from each other according to the principle of leverage.
Moreover, the double eyelid formation device 1' of another embodiment (second embodiment) further comprises fixing members 30 attached to the operation parts 11 for fixing the fingers.

The double eyelid formation device 1' of another embodiment (second embodiment) has a similar configuration to the double eyelid formation device of the above-mentioned embodiments unless otherwise specified, but differs from the double eyelid formation device of the first embodiment described above at least in that the connecting member 20 has a rod-shaped elastic body 25 instead of the two plate-shaped bodies 21 etc., as shown in FIG. 6, and that it further has two protruding members 40 protruding from each base material 10 towards the adjacent base material 10.
In the double eyelid formation device 1' of another embodiment (second embodiment), the base material 10 and the fixing member 30 may be the same as those described above.

In the double eyelid forming device 1' of another embodiment (second embodiment), the connecting member 20 has a rod-shaped elastic body 25 that connects the two base materials 10 together. The shape of the rod-shaped elastic body 25 is, for example, linear, curved, bent, or annular. The rod-shaped elastic body 25 deforms when force is applied to the operating part 11 of the base material 10, but has elasticity that allows it to return to its original shape when the force is released.

One end of the rod-shaped elastic body 25 is joined to one of the substrates 10, and the other end is joined to the other substrate 10. The shape of the rod-shaped elastic body 25 is, for example, annular as shown in FIG. 6. The annular rod-shaped elastic body 25 has a shape with part of a ring missing. Also, one end of the ring-shaped rod-shaped elastic body 25 is joined to one of the substrates 10, and the other end is joined to the other substrate 10.

More specifically, the ring-shaped rod-shaped elastic body 25 is arranged so as to penetrate the two substrates 10. More specifically, as shown in Figs. 6 to 8, both ends of the ring-shaped rod-shaped elastic body 25 are respectively joined to the outer surfaces of the plate-shaped portions of the adjacent substrates 10. The rod-shaped elastic body 25 is joined to the outer surface of one substrate 10 at one end, extends from the joined portion toward the operating unit 11 in the longitudinal direction of the substrate 10, and extends through a through hole formed in one substrate 10 into the space between the two substrates 10. The rod-shaped elastic body 25 is also joined to the outer surface of the plate-shaped portion of the other substrate 10 at the other end, extends from the joined portion in the same manner, and extends through a through hole formed in the other substrate 10 into the space between the two substrates 10. The rod-shaped elastic body 25 extending from both ends is connected in the space between the two substrates 10 to form a ring. The shape of this rod-shaped elastic body 25 is annular with part of the ring missing, and the opening of the missing part faces the abutment part 12 in the longitudinal direction of the substrate 10.

In the double eyelid forming device 1', a part of the ring-shaped rod-shaped elastic body 25 can serve as a fulcrum of the principle of leverage. Specifically, the part of the ring-shaped rod-shaped elastic body 25 with a part of the ring missing that is closest to the operating unit 11 can serve as a fulcrum of the principle of leverage. Specifically, when the two operating units 11 are brought closer to each other as described above in a state in which the two protruding members 40 described in detail later are not in contact with each other, the part of the ring-shaped rod-shaped elastic body 25 that is closest to the operating unit 11 (the central part farthest from both ends) serves as a fulcrum, and both ends of the ring-shaped rod-shaped elastic body 25 move away from each other (the space in the missing part of the ring expands) due to the principle of leverage. As a result, the central part serves as a fulcrum, and the distance between both ends of the ring-shaped rod-shaped elastic body 25 that are separated from each other widens, while the two abutting parts 12 move away from each other.

The rod-shaped elastic body 25 is made of, for example, resin. It is preferable that the material of the rod-shaped elastic body 25 is the same as the material of the base material 10.

The eyelid formation device 1' includes two protruding members 40. Each protruding member 40 protrudes from one of two adjacent substrates 10 toward the other. Each protruding member 40 is disposed between the operating portion 11 and the contact portion 12 in the longitudinal direction (extension direction) of the substrate 10. For example, each protruding member 40 is disposed closer to the operating portion than the rod-shaped elastic body 25 in the longitudinal direction of the substrate 10.

Each protruding member 40 has a semi-cylindrical shape, for example, a cylinder divided in half along the axis of the cylinder. Each semi-cylindrical protruding member 40 is joined to each base material 10. Specifically, the flat portion (cut surface when divided as described above) of the outer surface of each protruding member 40 is joined to each base material 10. Each semi-cylindrical protruding member 40 is arranged so that the cylindrical axis direction is the front-rear direction (the front-rear direction of the patient during use). In other words, the cylindrical axis direction of each semi-cylindrical protruding member 40 is perpendicular to both the longitudinal direction of the base material 10 and the direction in which the two base materials 10 face each other. The eyelid formation device 1' having two protruding members 40 arranged in this way is configured so that the outer surfaces of the protruding members 40 can abut (contact) each other. For example, as shown in FIG. 7, the curved surfaces of the protruding members 40 are configured to abut each other.

As shown in FIG. 7, for example, the eyelid formation device 1' is configured such that the curved surfaces of two semi-cylindrical protruding members 40 can make line contact with each other along the cylindrical axis direction. The two protruding members 40 are fixed to two substrates 10 (one substrate 10 and the other substrate 10), respectively. Therefore, when the distance between the contact portions of the two substrates 10 becomes closer or farther, the contact position on the curved surfaces of the two protruding members 40 changes. In other words, the curved outer surface of one protruding member 40 moves in a rolling manner in the circumferential direction on the curved outer surface of the other protruding member 40, thereby changing the contact position on the curved surfaces of the two protruding members 40.

The protruding member 40 is made of, for example, resin. It is preferable that the material of the protruding member 40 is the same as the material of the base material 10.

The area where the two semi-cylindrical protruding members 40 come into contact with each other (the area of line contact described above) can serve as a fulcrum of the lever principle in the double eyelid forming device 1'.

Referring to FIG. 7, when the contact portions of the two substrates 10 are closer to each other, the two protruding members 40 are separated from each other. When the distance between the operating parts 11 is reduced from this state, the part of the annular rod-shaped elastic body 25 closest to the operating parts 11 serves as a fulcrum until the two protruding members 40 come into contact with each other, and the distance between the contact portions 12 increases due to the principle of leverage. When the distance between the operating parts 11 is further reduced, the two protruding members 40 come into line contact with each other as described above. When the distance between the operating parts 11 is further reduced, the contact position of the parts where the two protruding members 40 come into line contact with each other (parts in line contact) changes, and the contact parts become a fulcrum, and the distance between the contact portions 12 increases further due to the principle of leverage.

According to another embodiment of the double eyelid forming device 1', in addition to the ring-shaped rod-shaped elastic body 25 that can serve as the fulcrum of the lever, the two protruding members 40 can also serve as the fulcrum of the lever. The two protruding members 40 abut against each other and act as the fulcrum, so that the fulcrum function is more stable. Therefore, the movement of the double eyelid forming device 1', in which the abutting parts move away from each other as the operating parts are brought closer to each other, becomes more stable. Therefore, the desired wrinkles can be created on the eyelids more easily and accurately.

Next, another embodiment (third embodiment) of the double eyelid forming device 1" will be described below.

The double eyelid forming device 1 ″ of another embodiment (third embodiment) is a double eyelid forming device for forming double eyelids by creating wrinkles in the left-right direction on the eyelids, as shown in FIG. 9 .
The device comprises two elongated base members 10 arranged parallel to each other, and a connecting member 20 connecting the two base members 10,
The base material 10 has, on one side and the other side in the longitudinal direction, a contact portion to be brought into contact with the eyelid and an operation portion 11 to receive a finger force for moving the base material 10,
The contact portions of the two base members 10 are adjacent to each other, and the operation portions are adjacent to each other.
Using the principle of leverage, at least a portion of the connecting member 20 serves as a fulcrum, and as the operating portions 11 are brought closer to each other, the abutting portions 12 are configured to move further away from each other.

In a double eyelid forming device 1 ″ of another embodiment (third embodiment), the connecting member 20 has a rod-shaped elastic body 25,
Both ends (one end and the other end) of the rod-shaped elastic body 25 in the longitudinal direction are joined to one base material 10 and the other base material 10, respectively.
A part of the rod-shaped elastic body 25 arranged between the two base members 10 serves as a fulcrum, and as the operation portions 11 are brought closer to each other, the contact portions 12 are configured to move further away from each other.

Unless otherwise specified, the double eyelid formation device 1" of another embodiment (third embodiment) has a similar configuration to the double eyelid formation device of the second embodiment described above; however, as shown in FIG. 9, it differs from the double eyelid formation device of the second embodiment at least in that it is not equipped with either the fixing member 30 or the protruding member 40.
In the double eyelid forming device 1 ″ of another embodiment (third embodiment), the same material as that described above can be used as the base material 10 .

The double eyelid forming device 1" of another embodiment (third embodiment) does not have a fixing member 30, but by directly placing a finger on the operating unit 11, as in the second embodiment described above, the part of the annular rod-shaped elastic body 25 closest to the operating unit 11 becomes the fulcrum, and by bringing the operating units closer together, the abutting parts can be moved away from each other. This operation creates wrinkles in the eyelids to form a double eyelid.
When using the double eyelid formation device 1" of another embodiment (third embodiment), the two substrates 10, which are spaced apart from each other, can be moved stably by inserting fingers between adjacent operation units 11. For example, the two substrates 10 can be moved stably by pressing the two substrates 10 from both sides with the thumbs and middle fingers to bring the operation units closer together, while inserting the index fingers between the two operation units 11. This makes it possible to stably increase the distance between the two contact portions 12, making it easier to create wrinkles.

The double eyelid forming device of each of the above-mentioned embodiments is preferably used, for example, to artificially change the eyelids of a patient who originally has a single eyelid into a double eyelid. It may also be used, for example, to make the eyes of a patient who has double eyelids look larger, to change the impression of the eyes by changing the double eyelids into ones with different wrinkle inclinations, such as parallel double eyelids and divergent double eyelids, to neatly arrange the shape of the wrinkles so that they match the shape of the eye opening (edge of the eyelid), and to change the original double eyelids into a different double eyelid. It may also be used, for example, to artificially form a tear bag on the lower eyelid.

When forming double eyelids using the double eyelid forming device of each of the above-mentioned embodiments, it is necessary to maintain the wrinkles created in the eyelids. Methods for maintaining the wrinkles include, for example, a method of sandwiching the wrinkles and adhering the skin on both the upper and lower sides with an adhesive, and a method of creating a coating on the surface of the eyelid, creating wrinkles, and maintaining the wrinkles by the shape-retaining power of the coating.
The double eyelid forming device of each of the above-mentioned embodiments may be used when forming a double eyelid by the former method, or may be used when forming a double eyelid by the latter method.

The double eyelid forming device of each of the above-mentioned embodiments can be used non-therapeutically for cosmetic purposes to improve the appearance of the eyes. Examples of cosmetic purposes include making the eyes appear larger, making the eyes appear younger, or changing the impression of the eyes due to droopy or slanted eyes according to preference.

The double eyelid forming device of the present invention is as exemplified above, but the present invention is not limited to the above-exemplified embodiment. In addition, the present invention can employ various forms that are used in general double eyelid forming devices, etc., as long as they do not impair the effects of the present invention.

The double eyelid formation device of each of the above-mentioned embodiments has a configuration in which the tip portions of the abutment portions 12 of the two base materials 10 can approach each other and abut, but the double eyelid formation device of the present invention may be configured to keep the two tip portions apart. For example, the double eyelid formation device of the present invention may include an abutment prevention member that prevents the two tip portions from abutting. The abutment prevention member is, for example, disposed between the two base materials and closer to the tip portions of the abutment portions in the longitudinal direction of the base materials than the portion that serves as the fulcrum of the lever principle. Also, for example, the double eyelid formation device of the present invention may have a configuration in which the rotation of the hinge mechanism of the engagement portion of the first embodiment is limited to prevent the two tip portions from abutting.
With this configuration, the two tip portions can be kept apart from each other, eliminating the need for an operation to separate the two tip portions that are in contact with each other, making the double eyelid formation device easier to use.

In the double eyelid forming device of the above embodiment, for example, two fixing members are simply attached to two base materials, but the double eyelid forming device of the present invention may be configured to be compact so that it can be easily stored when not in use. For example, the double eyelid forming device of the present invention may be configured so that the arrangement of the annular body can be changed with the joint between the base material and the annular body of the fixing member as the base point, and thus the surface direction of the virtual circle drawn by the annular body of the fixing member can be changed. Specifically, the double eyelid forming device may be configured so that the surface direction of the virtual circle and the direction in which the base materials face each other are perpendicular when not in use. In this case, the arrangement of the annular body may be changed so that the annular body of the fixing member and the abutment portion approach each other, or the arrangement of the annular body may be changed so that the annular body of the fixing member and the abutment portion move away from each other.
The double eyelid forming device may be configured so that the position of the annular body can be changed with the joint between the base material and the annular body of the fixing member as a base point so that the plane direction of the virtual circle is perpendicular to the front-rear direction during use. In this case, the position of the annular body may be changed so that the two base materials are sandwiched between the two annular bodies of the fixing member in the front-rear direction during use.

The double eyelid forming device of the present invention may further include a hook. To form a double eyelid, an adhesive or the like is required to fix the wrinkles created in the eyelid. For this reason, a container for storing the adhesive or the like is often required. Therefore, the double eyelid forming kit of the present invention includes at least the above-mentioned double eyelid forming device and a container for storing the adhesive to be applied to the skin to fix the wrinkles, and the double eyelid forming device may have a hook, and the container may have a hook receiver that engages with the hook. This allows the double eyelid forming device and the container to be stored together.
