Description

The present invention relates to a metallic glitter cap. More specifically, the present invention relates to a metallic luster pattern cap suitable for a cosmetic container cap or the like having a beautiful curved surface with a curved arc shape.

(Prior Art) Conventionally, as a cap such as a cosmetic container having metallic luster. Directly covered with a gold crown, transferred with a metal vapor deposition foil instead of being covered with a gold crown, in some cases transferred with a linear metal vapor deposition foil, and further pre-corroded with a gold crown, corrosion treatment In addition to the pattern transferred with a metal vapor deposition foil, the pattern transferred with an etching-processed plate, or the like by vacuum deposition of metal or chemical plating.

(Problems to be solved by the invention) In these caps having a metallic luster, a cap with a gold crown shows the original brilliance of metal, but there are many drawbacks in terms of process complexity, cost, etc. When a metal vapor deposition foil is used instead of a gold crown, even if it has an advantage of low cost, it is limited to the area where the glitter pattern by the metal vapor deposition foil is attached, and the original luxury and heavyness of the metal glitter pattern are lacking. In addition, the conventional engraving plate has a constant engraving, which causes little change.When deeply engraving, there is a problem that the material turns up at the edge of the plate. It is liable to be damaged, and when the foil is worn, the material may be exposed, resulting in a rough touch, unpleasant appearance, and unclear patterns.

As a result of various studies, the present inventors have reached the present invention,
The present invention press-transfers a hot stamp foil onto a surface of a base material made of a molding material such as plastics according to claim 1 by using an engraving tool capable of piercing a rope pattern or the like. A metallic bright pattern cap having a concave arc-shaped curved bright surface layer, and a desired pattern formed on the surface of a base material made of a molding material such as plastics according to claim 2. An object of the present invention is to provide a metallic glitter pattern cap characterized in that a depressed arc-shaped curved bright surface layer is formed by press-transferring a hot stamp foil using an electroforming plate in which a pattern or the like is duplicated. .

(Means for Solving the Problems) In order to achieve the above object, in the metallic glitter pattern cap of the present invention, the hot stamp foil is pressed against the surface of the substrate made of a molding material such as plastics. In the transferred structure, a recessed arc-shaped curved bright surface layer is formed by using an engraving tool capable of punching a rope-shaped pattern or the like, or an electroforming plate on which a desired pattern or pattern is reproduced. is there.

When the depression type arcuate curved bright surface layer is formed, the hot stamp foil is transferred by pressing the surface of the material with an embossing tool having a metal rope structure such as stainless steel, or the depression type The hot stamp foil is transferred by pressing the surface of the base material with an electroformed plate that can be punched with curved engraved parts, and the hot stamp foil is transferred to the base material using a conventional etching plate. Unlike the bright surface layer in which the recessed portion is formed of a concave recessed engraved portion, in the present invention, the maximum portion of the engraved portion is perforated in the shape of an arc of a pot bottom shape, and a net stamp foil is formed on the upper surface thereof. In this structure, the transferred curved bright surface layer is formed.

(Function) In the curved bright surface layer of the metallic glitter pattern cap configured as described above, when the hot stamp foil is pressed and transferred onto the surface of the substrate, it is strongly pressed in the conventional recessed engraving state. When it is inserted, the base material is turned up, and not only the foil is easily scratched by the edge of the plate, but also the disadvantages such as the foil being cut off at the bottom end edge portions of the concave depression and the base material being partially exposed. However, in the configuration of the present invention, the hot stamp foil is pressed and transferred onto the upper surface of the maximum portion of the engraved portion, which is a depression type, formed in the arc shape of the pot bottom shape, so that transfer foil breakage and the like are prevented. The metallic glitter is further improved by irregular reflection of the curved bright surface layer.

Further, even in the case of imprinting and pressing transfer onto the surface of a base material having a partial surface portion such as a cap, compared to the impact of an etching plate which forms a conventional concave depression state, it is formed in a curved shape in the present invention. Since it is pressed by the arcuate contact surface of a rope or the like, the impact when a stamping tool or electroforming plate is pressed against the surface of the base material is mitigated, and both ends of the recessed part are curled up. Even if a bulging part is formed on the curved drilled end, it is within the range that can be adjusted by the pressing conditions, etc., and the extent of that is the function of the boundary line demarcated by the recess. And acts to clarify the sharpness of the contour of the curved bright surface layer.

(Example) Hereinafter, the structure of the present invention will be described based on illustrated examples.

1 to 3, on the surface of the base material 2 of the metallic glitter pattern cap 1 made of plastics material, as shown in the partially enlarged sectional schematic view of FIG. A metallic bright pattern of discontinuous image lines is formed by a combination of a concave portion 3 which is engraved in a circular shape and a concave portion 3'which is also a narrow concave shape and is curved. 4 is a hot stamp foil adhesive layer, 5 is a metal vapor deposition layer, and 6 is a top coat layer, which is a concave and arcuate curved bright surface composed of concave portions 3 and 3'having the desired marking depth. A large number of layers 7 and 7'are formed as a discontinuous image line adjacent to the non-marked portion 8 which is not marked, and further, at the week edge end of the recessed curved concave portions 3 and 3 ' As shown in the figure, the bulging portion 9 in a slightly raised state is formed.

In FIG. 1 to FIG. 3, a metal stamped hot stamp foil is brought into contact with the surface of a base material 2 made of a plastics material, and a concave portion 3 such as a rope-like pattern is appropriately provided from the upper surface thereof.
Using an engraving tool (not shown) capable of forming 3 ', press transfer under the conditions of heating temperature, time, and pressure to form arcuate recessed portions 3, 3'of a desired engraving depth. In the concave portion, as shown in FIG. 2, the adhesive layer 4, the metal vapor deposition layer 5 and the top coat layer 6 are integrally bonded and fixed with the adhesive layer 4 inside, and the arc-shaped depressed curved bright surface. The layers 7, 7'are formed. As shown in FIG. 1, a large number of wide recesses 3 and a narrow width of recesses 3 ′ are formed as a discontinuous image line on the surface of the base material 2 in a geometric pattern as a whole. The recessed arc-shaped curved bright surface layers 7 and 7 ′ have extremely excellent sharpness of the contour of the drawing due to the presence of the adjacent non-engraved portion 8 or the bulging portion 9, and have a recessed curved shape. In addition, since the holes are formed discontinuously, a pattern having an extraordinary and prominent metallic luster is manifested due to diffuse reflection different from, for example, protrusions.

The bulging portion 9 at the peripheral edge of the recessed portions 3 and 3'is also to the extent that the hot stamp foil is pressed and transferred to the portion to make it good, and the image line of the metallic glitter pattern is more clearly shown. The metallic glitter pattern cap 1 is, for example, a rope-like body made of metal such as stainless steel and having a mesh size of about 70 mesh or less, and a rope-like pattern impregnated with silicone if necessary, on the surface of a molding made of an AS resin base material 2. Engraving tool (not shown) capable of forming
Using appropriate heating temperature, time, and pressure conditions, press transfer is performed to form arc-shaped recesses 3 and 3 ′ having a desired marking depth, and in the recesses, an adhesive agent for hot stamp foil is used. Curved bright surface layers 7 and 7'in which the metal vapor deposition layer 5 and the top coat layer 6 are integrally bonded and fixed with the layer 4 inside, are formed. With such a configuration, unlike the conventional concave recessed portion, both the shallow portion of the marking and the deep portion of the pot bottom at the maximum portion of the concave portion are obtained on the curved arc surface, and Depression part
Since the brilliance of 3,3 'is remarkably different, a metal brilliant pattern cap having a wide variety of brilliance can be obtained by appropriately setting the desired pattern depth.

The metallic luster pattern cap of the invention described in claim 1 has the above-mentioned constitution.

Next, FIG. 4 and FIG. 5 show the structure described in claim 2 of the claims, and in the figures, the curved concave portions 3, 3 ′ are shown.
Is the same as that of FIG.
Has a wide width and the recess 3'has a narrow width. In this case, a slightly raised bulge 9 is formed at the peripheral edge of the curved recess 3,3 ', and a hot stamp inside. The foil adhesive layer 4, the metal vapor deposition layer 5, and the top coating layer 6 are commonly bonded and fixed in this order to exhibit a curved arc shape. However, claim 1 is a substantially monotonous curved depression type. On the other hand, in claim 2, although the recessed portions 3 and 3'perforated as shown in FIG. 5 are of a curved type, the constituent elements thereof have a relatively short number of wavelengths. It has a structure in which a protrusion is formed. Further, in the second aspect, since an electroforming plate capable of precise copying is used, either continuous image lines and / or discontinuous image lines can be adopted as desired.

The metallic luster pattern cap 1'shown in FIG. 6 is hot stamped, for example, by using an electroforming plate (not shown) in which a fiber plain weave pattern is precisely duplicated on the surface of a molding cap made of resin as the base material 2. The adhesive layer 4 of the foil is superposed on the surface of the base material 2 and transferred by pressure at an appropriate heating temperature, time and pressure, and the adhesive layer 4, the metal deposition layer 5 and the top coat layer 6 of the hot stamp foil are stacked. To obtain a metallic bright pattern cap having curved bright surface layers 7 and 7'where hot stamp foil is pressed and transferred to appropriately curved concave portions 3 and 3'which are integrally bonded and fixed with the adhesive layer 4 inside be able to. If necessary, the curved bright surface layers 7, 7'and the non-engraved portion 8 may be overcoated at a required temperature.

The metallic luster pattern cap of the invention described in claim 2 has the above-mentioned constitution.

Further, in the case of the metallic glitter pattern cap according to the present invention, in the case where glittering property or decorative property is further required, a stamping tool capable of marking a desired pattern, pattern or the like is used, various combinations are adopted, and a hot stamp foil is formed. It is also possible to adopt a configuration in which two or more steps of pressure transfer are performed.

In the present invention, the depth of the curved bright surface portions 7 and 7'where hot stamp foil is pressed and transferred to the curved concave portions 3 and 3'is engraved, and there are differences in the design, etc., but the curved portion of the arc shape. In the maximum part of the above, it is about 500 μ or less, preferably about 10 to 300 μ. When the thickness is about 10 μm or less, the depth of the recessed portion due to the engraving is shallow, so that there are disadvantages that the desired glittering change and the decorativeness are poor. Further, if the engraved portion is deep, for example, the pressing thickness is too strong, the temperature is too high, or the pressing time is not appropriate, the hot stamp foil is easily cut at the edge and discoloration of the vapor deposition foil occurs, There is a problem such as the exposure of the base material, which makes it difficult to perform the pressure transfer work smoothly.

The configurations described in claims 1 and 2 of the present invention are not limited to cosmetic container caps, but may be any other compact containers, as long as they are made of a molding material such as watches or sundries.

(Effects of the Invention) The metallic glitter pattern cap of the present invention has a curved arc-shaped recess formed by pressing and transferring a hot stamp foil onto the surface of a molding material such as plastics using an engraving tool or an electroforming plate. Since the bright surface layer is formed, various different brilliant metallic glitter patterns can be revealed by appropriately setting the engraving depth of the recess.

Further, in the metallic glitter pattern cap of the present invention, in the case of the conventional engraving plate, etc., the depth of the concave engraving part is constant and scarcely changes, and when strongly pressed and transferred to obtain a deep engraving, the product or foil is damaged. It is possible to solve the difficulty that is easy to do.
In addition, the metallic luster of the bright surface layer of the concavely curved shape differs depending on its depth, and by appropriately selecting an engraving tool or electroforming plate and setting the pressure transfer conditions, metallic luster patterns of various wide designs can be obtained. There is also an effect that the cap can be revealed at a low cost by a simple process connection.
