Description

  The present invention relates to a nail art stamp that can be easily stamped by repeating a pattern on the surface of a nail.

In recent years, nail art for drawing a pattern on the surface of a nail with a brush or pen using various color nail polish has been widely performed.
In order to draw a beautiful pattern on the surface of the nail with a brush or pen, there is a problem that it requires some skill and takes a long time.
In order to solve this, a nail art is applied to the nail surface by pressing the stamp portion against the nail surface of the finger placed on the upper surface of the nail surface of the finger positioned on the upper surface and the nail surface positioned by placing the finger on the upper surface. Proposed is a nail art stamp apparatus comprising: a stamp body for transferring an image; and a guide frame that is positioned on the stamp stand and guides the pressing operation of the stamp body to guide the stamp portion to an appropriate position with respect to the nail surface. (See Patent Document 1).

However, the above-mentioned prior art requires that a pattern be transferred by applying a coating agent such as ink or nail polish to the surface of the stamp part once and then pressing the nail surface. There is a problem in that an operation of attaching the coating agent to the film is necessary.
It is an object of the present invention to provide a nail art stamp capable of repeatedly and easily drawing a pattern on a nail surface.

As a result of intensive studies to solve the above problems, the present inventor has found that the above problems can be solved, and has completed the present invention.
That is, according to the present invention, a penetrating mark made of a porous elastic body is provided at the tip of a handle, and the penetrating mark can absorb and hold nail ink, and a pattern-shaped nail ink stain is formed on the surface of the penetrating mark. The present invention provides a nail art stamp capable of being repeatedly stamped, characterized by having a lead-out portion.
The present invention also provides a nail art stamp in which the pattern-shaped nail ink oozing portion is a pattern-shaped convex protrusion in the nail art stamp.
The present invention also provides a nail art stamp in which a penetrating mark is provided between the tip of the handle and the penetrating mark via a holder.

The present invention also provides a nail art stamp in which the body of the holder is thinner than the thickness of the handle.
The present invention also provides a nail art stamp in which the penetrating mark is provided at the tip of the handle via a cushioning material.
The present invention also provides a nail art stamp in which the cushioning material is a sponge-like elastic body and the penetrating mark is attached to the cushioning material via an adhesive layer.
The present invention also provides a nail art stamp in which a weight is built in a holder in the above nail art stamp.
The present invention also provides a nail art stamp in which the nail ink is absorbed and retained in the permeation mark.

  The nail art stamp of the present invention can be repeatedly and easily drawn on the surface of the nail.

The nail art stamp of the present invention will be described with reference to the drawings.
FIG. 1 shows a perspective view of one embodiment of the nail art stamp of the present invention, and FIG. 2 shows a state of the nail art stamp of the present invention in a state in which the handle, the holder and the cap are pulled apart. A cross-sectional view is shown, and FIG. 3 shows a cross-sectional view in which the handle of the nail art stamp of FIG. 2 is moved in the direction of the arrow and connected to the holder, and the cap is pulled apart.
4 and 5 each show a schematic cross-sectional view of an embodiment of the nail art stamp of the present invention at the upper part thereof, and a plan view of the permeation mark at the lower part thereof. In addition, the arrow described in the plan view of the permeation mark means that the section showing the arrow is a schematic sectional view of the upper part.

  The permeation mark 3 is made of a porous elastic body. The porous elastic body can absorb and hold nail ink. Further, the permeation mark 3 has a pattern-shaped nail ink exuding portion on the marking surface. Thereby, when the penetration mark 3 is pressed against the surface of the nail, the nail ink can ooze out from the pattern-shaped nail ink oozing portion provided on the marking surface. In order to exhibit this function, it is necessary that the pores in the porous elastic body communicate with each other. The diameter of each hole is not particularly limited, but the average diameter of the holes is preferably 1 to 100 μm, more preferably 6 to 50 μm, more preferably 12 to 30 μm, and particularly preferably 15 to 25 μm. As the porous elastic body, a continuous foamed porous elastic body is optimal.

Further, the porous elastic body of the permeation mark 3 needs to have a capacity capable of absorbing and holding enough nail ink so that the pattern can be repeatedly stamped on the surface of the nail, and the capacity is preferably repeated more than 30 times. It is a capacity that can be repeatedly stamped 50 times or more. The upper limit of the capacity is preferably a capacity that can be repeatedly stamped 200 times or less, more preferably a capacity that can be repeatedly stamped 150 times or less, and particularly preferably a capacity that can be repeatedly stamped 120 times or less. If the capacity is too large, a problem occurs when the long-term storability of the nail ink is poor.
Moreover, 0.1-10 mm is preferable, as for the thickness of the porous elastic body of the penetration mark 3, 0.3-5 mm is more preferable, and 0.5-2.5 mm is especially preferable.

  The porous elastic body of the permeation mark 3 is manufactured from one or a mixture of two or more kinds of natural rubber, synthetic rubber and thermoplastic elastomer, and a mixture of natural rubber and synthetic rubber or thermoplastic elastomer is preferable. Examples of the synthetic rubber include ethylene-propylene rubber, ethylene-propylene-diene rubber, ethylene-vinyl acetate rubber, butadiene rubber, chloroprene rubber, styrene-butadiene rubber, acrylic rubber, silicone rubber, polyurethane rubber, and the like. Examples of the thermoplastic elastomer include polyolefin-based thermoplastic elastomers, chlorinated polyethylene-based thermoplastic elastomers, polystyrene-based thermoplastic elastomers, polyurethane-based thermoplastic elastomers, polyester-based thermoplastic elastomers, polyamide-based thermoplastic elastomers, and the like. Of these, polyolefin-based thermoplastic elastomers are preferable, and polyethylene-based thermoplastic elastomers are particularly preferable.

  The porous elastic body can be obtained by mixing a foaming agent into the rubber or thermoplastic elastomer or a precursor thereof and foaming. Further, a foam having closed cells is broken by using a needle punch or the like to obtain open cells, or a rubber and / or elastomer described in JP-B-47-39212 is used as a polyolefin-based thermoplastic elastomer. A method of treating with calcium sulfite or an inorganic acid that dissolves calcium sulfate, as described in JP-B-57-42651, nonionic surfactant or polyhydric alcohol, water or acidic aqueous solution insoluble in organic solvents A method of washing a molded product obtained by kneading with a polyolefin thermoplastic elastomer, which is soluble in a powdery material, and molding this, such as calcium carbonate and magnesium carbonate described in the specification of Japanese Utility Model No. 53-143033 The polyolefin resin is uniformly filled with acid-soluble fine particles that are soluble in acid, and then circled with an extruder. After molding to Jo, to dissolve the fine particles filled with hydrochloric acid or nitric acid, a method of obtaining a continuous porous body of porosity 60% to 70% can be mentioned.

The nail ink oozes out from the nail ink oozing portion on the surface of the penetrating mark 3 and adheres to the surface of the nail, thereby forming a pattern. Therefore, the nail ink exudation portion on the surface of the permeation mark 3 has a pattern shape.
A pattern can be made into various shapes, such as a character, a symbol, a line, a mark, or one or a combination of two or more thereof. Specific examples of patterns include, for example, heart marks, stars, human faces, lips, eyes, heads, hands, fingers, feet, etc., plants such as flowers, leaves, trees, grass, dogs, cats, rabbits, birds Various patterns such as animals such as animals, statues, buildings, and towers can be mentioned. The maximum size of the pattern is preferably in the range of 1 to 10 mm, particularly preferably in the range of 1 to 5 mm.

The marking surface of the permeation mark 3 may be a flat surface, but is preferably provided with a convex protrusion 2. It is preferable that the tip of the convex protrusion 2 is a flat surface. The flat portion at the tip of the convex protrusion 2 may be a pattern.
The thickness of the convex protrusion 2 is preferably 0.01 to 2 mm, and more preferably 0.02 to 0.5 mm. If the thickness of the convex protrusion 2 is too large, the nail is curved and slippery, which is not preferable because the pattern is shifted when stamped on the nail.
The place where the nail ink oozes out from the permeation mark 3 is preferably only the flat portion at the tip of the convex protrusion 2. That is, it is preferable that the surface of the permeation mark 3 on which the convex protrusion 2 is not provided closes the hole of the porous elastic body so that the nail ink does not ooze out. Moreover, it is preferable that the side surface part of the convex projection part 2 also closes the hole of the porous elastic body so that the nail ink does not ooze out.

Further, when the protruding surface 2 is not provided on the surface of the penetrating mark 3, the surface of the penetrating mark 3 other than the nail ink exuding portion is porous elastic so that the nail ink does not exude. It is preferable to close the body hole. Thereby, the nail ink oozes out only from the pattern portion, and a clear pattern can be formed on the nail.
As a method for closing the pores of the porous elastic body, the surface of the porous elastic body is fused and sealed by a method of covering with a non-porous film, a plate making process using a thermal head, a plate making process using flash flashing, a thermal transfer method, etc. The method etc. are mentioned.

In the plate making process using flash flashing, the surface of the porous elastic body is irradiated with light such as infrared rays, and the heating material is heated so that it becomes a mirror image and negative with respect to the pattern shape. By melting the surface layer, a non-nail ink bleeding portion and a nail ink bleeding portion are formed.
As a specific example of the plate making process by flash flashing, for example, light is applied to the surface of a porous elastic body in which a black pigment such as carbon black is previously blended or a layer containing a black pigment is laminated on the surface in advance. Examples of the method include producing a penetrating mark made of a porous elastic body in which open cells are blocked by heating the black pigment to melt the surface of the porous elastic body. In addition, it can replace with a black pigment | dye and the other heat generating material which generate | occur | produces with the light irradiated from a light source can be used. Examples of other heat generating materials include phthalocyanine pigments (see, for example, JP-A-9-314972). In addition, to form a layer containing black pigment, a composition containing black pigment, a resin component and, if necessary, a diluent is applied to the surface of the porous elastic body and dried as necessary. can do. As a resin component, the resin component etc. which are used for a normal adhesive agent are mentioned. The resin component preferably has no adhesiveness after light irradiation.

The penetrating mark 3 may be directly attached to the tip of the handle 1, but the holder 5 of the penetrating mark 3 may be held and attached to the tip of the handle 1. When the holder 5 is equipped, the handle 1 and the permeation mark 3 can be easily attached. The holder 5 has a handle attachment portion 7 and a penetration mark attachment portion 6.

A shape similar to that of the handle 1 is preferable.
The body portion 8 of the holder 5 is preferably thinner than the handle 1. If the body portion 8 of the holder 5 is thick, the position where the pattern is applied may not be clearly recognized when stamped on the nail as viewed from above the handle 1. By narrowing the trunk portion 8 of the holder 5, there is an advantage that it is easy to clearly recognize the position where the pattern is applied when stamping on the nail as viewed from above the handle 1. In particular, when the thickness of the handle 1 is 10 mm or more, it is preferable to make the trunk portion 8 of the holder 5 thinner. The degree of thinning is preferably 5 to 50% thinner than the thickness of the handle 1 and particularly preferably 10 to 40% thinner.

The thickness of the buffer material 4 is preferably 1 to 20 mm, more preferably 5 to 15 mm, and particularly preferably 7 to 13 mm.

The buffer material 4 is preferably one that is crushed and shrunk when force is applied. The cushioning material 4 that is crushed and shrunk can reliably give the pattern of the nail art stamp to the surface of the nail that is a curved surface when stamping on the nail with the nail art stamp. When the nail art stamp is released from the nail, the cushioning material 4 that has been crushed and shrunk returns to its original shape.
The degree to which the cushioning material 4 is crushed and shrunk is preferably 20 to 90%, particularly 30 to 70%, with respect to the thickness when no force is applied when actually stamping the nail with a nail art stamp. preferable.

Preferably, 1.5 to 4 mm is particularly preferable.

  In order to adhere the permeation mark 3 to the buffer material 4, it may be adhered via an adhesive layer, or may be adhered by thermal fusion or the like. When the penetrating mark 3 is adhered to the buffer material 4 via the adhesive layer, it is possible to prevent the nail ink soaked in the penetrating mark 3 from being soaked into the buffer material 4. As an adhesive used for the adhesive layer, various adhesives can be used.

It is preferable that the buffer material 4 does not soak or hardly soak nail ink. That is, it is preferable that the nail ink is soaked only in the porous elastic body constituting the permeation mark 3. It is not preferable that nail ink soaks into the buffer material 4, since the nail ink soaked into the buffer material 4 oozes out and adheres to the nail when a nail art stamp is applied to the nail.
As for the length of the buffer material 4, 1-30 mm is preferable normally and 3-22 mm is especially preferable.
The cushioning material 4 with the permeation mark 3 is attached from the tip of the handle 1 when attached only to the handle 1 without the holder 5, or from the tip of the holder 5 when the holder 5 is attached to the handle 1.

The interval between the convex outer ring zones 10 is preferably 0.5 to 5 mm, and particularly preferably 0.8 to 3 mm.

The outer periphery of the holder 5 may be threaded instead of the convex outer ring zone 10, and the cap 13 may be attached to the holder 5 by further threading the inner surface of the cap 13. Moreover, as shown in FIG. 3, when threading 15 is performed together with the convex outer ring zone 10 on the outer periphery of the holder 5, the airtightness of the cap 13 can be further enhanced.
In order to prevent the nail ink from evaporating, it is preferable to increase the airtightness of the cap 13 by laminating a thin film 16 on the inner surface of the cap 13.
Examples of the material of the thin film 16 include the same rubber and elastomer as the material of the permeation mark 3 and the buffer material 4, and further, the same resin as the material of the handle 1 can be mentioned. A soft material is preferred.

Specifically, it is preferable to provide a convex flange 9 on the outer periphery of the holder 5. It is preferable that the convex flange 9 also functions as a handle for fitting the handle when fitted with the handle 1.
The holder 5 is preferably formed by integrally forming the groove 11, the groove 12, the convex outer ring band 10, and the convex flange 9.

  The penetration mark 3 can be joined to the nail ink tank 17 as shown in FIG. In this case, when the nail ink in the permeation mark 3 is used, the nail ink can be infiltrated sequentially from the nail ink tank 17. The nail ink tank 17 is preferably structured to be stored inside the handle 1. The top of the nail ink tank is preferably sealed so as to be removable with a tank lid 18. Connecting the nail ink tank 17 to the holder 5 is preferable because it can be easily attached to the handle 1.

The nail ink occlusion body 19 made of the same material as the permeation mark 3 is preferable because both can be easily thermally bonded and bonded together.

In addition, it is preferable that the upper part of the nail ink occlusion body 19 accommodates a hard presser 20 that functions to support the permeation mark 3 so as not to fall into the handle 1.
Examples of the material of the hard presser 20 include hard plastic and hard foamed plastic (such as hard foamed polystyrene).
It is preferable to prevent a pattern error or a color error by displaying the color or pattern of the nail ink on the top or side of the pattern 1.
In addition, if the holder 5 is equipped, the handle 1 and the permeation mark 3 can be easily replaced. In this case, if the handle 1 is made of a transparent or translucent material, the holder 5 can be easily seen from the outside of the handle 1 and is absorbed and held by the penetrating mark 3 on the surface of the holder 5 or the nail ink tank 17. It is preferable to display the color of the nail ink that is present since the color of the nail ink can be confirmed from the outside of the pattern 1 while the pattern 1 is held by hand even after the pattern 1 is attached.
