DUST-FREE ARTIFICIAL NAIL
TECHNICAL FIELD
The following disclosure relates to a dust-free artificial nail, and in
particular, to a dust-free artificial nail which seals a gap between the
artificial
nail and a nail in order to prevent a hair from being caught between the
artificial nail and the nail.
BACKGROUND
Generally, an artificial nail bed with a nail shape is attached to a nail to
freely change the change of the nail. At this time, the artificial nail bed is
attached to the nail by using an adhesive.
However, as shown in FIG. 1, a gap creates between an artificial nail
bed 10 and a nail 1 due to the thickness of an adhesive 5 used for attaching
the artificial nail bed 10. Therefore, if unconsciously touching hairs in a
state
where the artificial nail bed 10 is attached to the nail, a hair is caught at
the
gap between the nail and the artificial nail bed 10 and stuck to the adhesive
5, which makes the adhesive dirty. In this case, the adhesive performance of
the adhesive deteriorates, and the hair caught at the artificial nail due to
the
adhesive causes a pain and thus gives a person an unpleasant feeling. In
other words, while the hair is caught, impurities may easily penetrate into
the
adhesive, which deteriorates the adhesive force of the adhesive 5 and allows
the artificial nail bed 10 to be easily separated from the nail 1. In
addition,
since the other end 14 and a nail wall 16 of the artificial nail bed 10 are
1
CA 02794041 2012-11-01
exposed, when a person grips an article by the hand, the other end 14 or the
nail wall 16 may collide with the article, which may make the artificial nail
bed
be instantly separated from the nail 1. At this time, if the artificial nail
bed
10 is abruptly separated from the nail 1, an impact may be applied to the nail
1, which may cause a pain. In addition, while a person is moving, the other
end 14 and the nail wall 16 of the artificial nail bed 10, exposed out, may
scratch a human body and make a hurt thereto.
SUMMARY
An embodiment of the present disclosure is directed to providing a
dust-free artificial nail which prevents a hair from being caught at an
artificial
nail by sealing a gap between the artificial nail and the nail and allows an
adhesive force of an adhesive to be maintained for a long time by preventing
impurities from penetrating into the adhesive while the hair is caught.
In one general aspect, there is provided a dust-free artificial nail, which
includes: one end formed to have a curvature in the same direction of a free
edge of a nail; the other end located at an opposite side to one end; an
artificial nail bed having nail walls located at both sides of one end and the
other end and having a nail shape so that an adhesion surface thereof is
attached to the nail; and a snug fit extending from the other end of the
artificial nail bed and having a curved surface toward the adhesion surface.
According to an embodiment of the present disclosure, the snug fit may
further extend from the wall of the artificial nail.
In addition, the dust-free artificial nail may further include an adhesive
2
CA 02794041 2012-11-01
attached to the adhesion surface; and a protrusion formed on the adhesion
surface at a border line of the adhesive toward one end of the dust-free
artificial nail.
At this time, the thickness of the protrusion may be 50% to 100% of the
thickness of the adhesive.
In addition, the length of the snug fit may be 1% to 30% of the length of
the artificial nail bed.
In addition, the snug fit may be inclined at 5 to 80 from an upper
surface of an end of the artificial nail bed oriented to a nail wall toward
the
adhesion surface.
According to the present disclosure, since a gap between the nail and
the artificial nail bed may be minimized, it is possible to prevent a hair
from
being caught at the artificial nail when the hair is arranged by using the
hand,
thereby minimizing the inconvenience of a user. In addition, since it is
minimized that dust enters through the gap between the nail and the artificial
nail bed, the adhesive may maintain its adhesive force for a long time, and it
is possible to prevent the artificial nail bed from being separated from the
nail
as the other end and the nail wall of the artificial nail bed are collided
with an
article during activity. In addition, even though the nail grows for a certain
period, the other end of the artificial nail bed may be kept in contact with a
cuticle.

DETAILED DESCRIPTION OF EMBODIMENTS

CA 02794041 2012-11-01
FIG. 2 is a perspective view showing a dust-free artificial nail 100
according to an embodiment of the present disclosure.
As shown in FIG. 2, the dust-free artificial nail 100 according to the
present disclosure includes one end 112 formed to have a curvature in the
same direction as a free edge of a nail 1, the other end 114 located at an
opposite side to one end 112, an artificial nail bed 110 having nail walls 116
located at both sides of one end 112 and the other end 114 and having a nail
shape so that an adhesion surface 119 thereof is attached to the nail, and a
snug fit 120 extending from the other end 114 of the artificial nail bed 110
and curved toward the adhesion surface 119.
The snug fit 120 may not only extend from the other end 114 but also
extend along the nail wall 116. As the snug fit 120 is formed to extend from
the other end 114 and the nail wall 116 of the artificial nail bed 110, a gap
formed between the artificial nail bed 110 and the nail 1 may be closed due
to the thickness of an adhesive 5.
In other words, if the adhesive 5 is applied to an adhesion surface 119
which is a lower surface of the artificial nail bed 110, the artificial nail
bed 110
is attached to the nail 1 by means of the adhesive 5. At this time, since the
adhesive 5 has a certain thickness, a gap is formed at an contour line of the
artificial nail bed 110 where the adhesive 5 is not applied, and impurities
such
as hairs and dust penetrate into the gap. Therefore, the adhesive 5 and the
artificial nail bed 110 may be contaminated, and the adhesive force of the
adhesive 5 may be deteriorated due to the impurities. In order to solve this
problem, in the present disclosure, the snug fit 120 is formed at a contour
portion of the artificial nail bed 110 except for its one end 112, namely to
CA 02794041 2012-11-01
extend from the other end 114 and the nail wall 116.
FIG. 3 is a cross-sectional view showing the dust-free artificial nail 100
according to an embodiment of the present disclosure, which is attached to
the nail 1.
First, the snug fit 120 of the dust-free artificial nail 100 according to the
present disclosure is formed to extend from the other end 114 of the
artificial
nail bed 110. Since the snug fit 120 is curved toward the adhesion surface
119, it is possible to prevent impurities from penetrate from the other end
114
where a cuticle Q is located. At this time, in the dust-free artificial nail
100,
as shown in FIG. 3a which is an enlarged view, the snug fit 120 located at the
other end 114 may be attached to the nail 1 in a state of being further curved
with the force toward one end 112 while supporting the cuticle Q.
If the dust-free artificial nail 100 is attached to the nail 1 so that the
snug fit 120 receives a force, even though the nail 1 grows for a certain
period, a gap may not be created between the cuticle Q and the dust-free
artificial nail 100. In other words, as shown in FIG. 3b which is an enlarged
view, if the force supporting the cuticle Q is lessened as the nail 1 grows,
the
snug fit 120 supports the cuticle Q, and so the degree of curving becomes
gentle. Therefore, even though the actual length of the snug fit 120 has not
changed but the length of the nail 1 changes, the snug fit 120 keeps in
contact with the cuticle Q, and so a gap is not crated between the cuticle Q
and the dust-free artificial nail 100. By adhering the snug fit 120 to the
nail 1
as described above, it is possible to prevent impurities from being caught
between the artificial nail bed 110 and the nail 1. In addition, even though
the nail grows for a certain period, the snug fit 120 may keep in a contact
with
6
CA 02794041 2012-11-01
the cuticle.
The dust-free artificial nail 100 according to the present disclosure may
also be attached to the nail 1 from the first, as shown in FIG. 3b which is an
enlarged view. In other words, the dust-free artificial nail 100 may be
attached to the nail so that the snug fit 120 does not receive a force by the
cuticle Q.
In addition, a protrusion 118 may be further formed at the adhesion
surface 119 of the dust-free artificial nail 100. The adhesive 5 may not be
attached to the entire adhesion surface 119 but may be attached to a part
thereof. At this time, since the snug fit 120 is formed except for a portion
of
one end 112 of the artificial nail bed 110, the adhesive 5 may be isolated
from impurities. Further, in a
dust-free artificial nail according to an
embodiment of the present disclosure, the protrusion 118 may also be
installed at one end 112 of the artificial nail bed 110 so that the adhesive 5
is
isolated from impurities. In other words, the protrusion 118 may be formed to
protrude at a location of the border line of the adhesive 5 located at one end
112 of the artificial nail bed 110. The protrusion 118 may be formed along
the entire border line of the adhesive and also be formed as a plurality of
dots. If the protrusion 118 is formed as described above, it is possible to
prevent impurities from being stuck in the gap formed by the adhesive 5 at
one end 112 of the artificial nail bed 110.
At this time, the height of the protrusion 118 is preferably 50% to 100%
of the thickness of the adhesive 5. For example, if the thickness of the
adhesive 5 is assumed to be 1, if the height of the protrusion 118 is smaller
than 0.5, a gap between the protrusion and the nail increases, and so
7
CA 02794041 2012-11-01
impurities may penetrate between the protrusion 118 and the nail 1. If the
height of the protrusion 118 exceeds 1, the dust-free artificial nail 100 may
not be easily adhered to the nail 1 due to the protrusion 118. In other words,
if the height of the protrusion 118 is in the range of 0.5 to 1, even though a
gap is present between the protrusion 118 and the nail 1, it is possible to
prevent impurities from penetrate through the gap.
In the dust-free artificial nail 100 according to the present disclosure,
the adhesive 5 may be either a double-sided adhesive tape or a nail glue.
FIG. 4 is a front view showing the dust-free artificial nail 100 according
to an embodiment of the present disclosure, which is mounted to the nail 1.
As shown in FIG. 4, the snug fit 120 extending from the nail wall 116
prevents impurities from being caught in a gap formed between the side of
the nail 1 and the artificial nail bed 110 due to the adhesive 5. In addition,
it
is possible to prevent the artificial nail bed 110 from colliding with an
article
and being separated from the nail 1, and it is also possible to prevent a
human body from being damaged due to an end of the nail wall 116. In other
words, different from a conventional artificial nail where the other end 114
and the nail wall 116 of the artificial nail bed 110 are exposed, the dust-
free
artificial nail 100 according to the present disclosure gives an effect as if
the
other end 114 and the nail wall 116 of the artificial nail bed 110 come in
contact with the nail 1 due to the snug fit 120 extending from the artificial
nail
bed 110. Therefore, it is possible to prevent the dust-free artificial nail
100
from colliding with an article and being separated, and it is also possible to
prevent the other end 114 and the nail wall 116 of the artificial nail bed 110
from scratching and injuring a human body.

CA 02794041 2012-11-01
FIG. 5 is a partially-sectioned view showing the dust-free artificial nail
according to an embodiment of the present disclosure. Even though FIG. 5
shows only the snug fit 120 connected to the other end 114 of the artificial
nail bed 110 for easy understanding, the snug fit 120 connected to the nail
wall 116 of the artificial nail bed 110 is also formed with the same
conditions
and with the same angle and length as the snug fit 120 connected to the
other end 114, without being limited to the above.
As shown in FIG. 5, the dust-free artificial nail according to the present
disclosure has a greater curvature than the artificial nail bed 110.
Therefore,
the snug fit 120 is curved further toward the adhesion surface 119 in
comparison to the artificial nail bed 110. At this time, at a point where the
snug fit 120 and the artificial nail bed 110 encounter, an angle 0 between a
tangential line of the upper surface of the snug fit 120 and a tangential line
of
the upper surface of the artificial nail bed 110 is in the range of 50 to 80 .
This allows a gap between the artificial nail and the nail to be effectively
closed by the snug fit. If the angle 0 is smaller than 5 , the curvature is
similar to that of the artificial nail bed, and so hairs or impurities may
penetrate thereto. In addition, if the angle 0 exceeds 80 , the terminal of
the
snug fit 120 may push the nail and apply a force in a direction opposite to
the
adhesive force of the adhesive 5. Therefore, at a point where the snug fit
120 and the artificial nail bed 110 encounter, the angle 0 between the
tangential line of the upper surface of the snug fit 120 and the tangential
line
of the upper surface of the artificial nail bed 110 is in the range of 5 to
80 .
In addition, regarding the length t of the snug fit 120, the length
connected to the artificial nail bed 110 may vary according to the angle 0 of
9
CA 02794041 2012-11-01
the snug fit 120. Here, the length of the snug fit 120 is preferably 1% to 30%
of the length of the artificial nail bed 110. If the length of the snug fit
120 is
smaller than 1% of the length of the artificial nail bed 110, even though the
snug fit 120 has an angle 0 of 80 , hairs or impurities may be caught in the
gap between the artificial nail and the nail due to the small length. In
addition, since the snug fit 120 has a greater curvature than the artificial
nail
bed 110, if the length of the snug fit 120 exceeds 30% of the length of the
artificial nail bed 110, when being applied to the nail, the attachment force
of
an adhesive tape located at the end of the artificial nail bed 110 formed at a
mounting location of the snug fit 120 and near the nail wall may be
deteriorated. Therefore, the length of the snug fit 120 is preferably 1% to
30% of the length of the artificial nail bed 110. Here, the length of the
artificial nail bed 110 represents not only a length between one end 112 and
the other end 114 of the artificial nail bed 110 but also a length till the
nail
wall 116. Therefore, the length of the snug fit 120 connected to the nail wall
116 is substantially determined based on a length of the artificial nail bed
110
in the width direction.
While the present disclosure has been described with respect to the
specific embodiments, it will be apparent to those skilled in the art that
various changes and modifications may be made without departing from the
spirit and scope of the disclosure as defined in the following claims.
