Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hologram transfer sheet, and more particularly to a hologram transfer sheet for decorating a curved surface of a container surface having a side peripheral wall formed by a plane curved surface.

[0002]

It has been known in the past to transfer a holographic display on a two-dimensional plane using a hologram transfer sheet. However, curved surfaces,
In particular, the transfer of the holographic display member to the surface of the container formed of a drum-shaped elliptical surface of revolution has not been carried out.

In the side peripheral wall formed by a drum-shaped elliptical surface of revolution or the like, in order to bring the transfer sheet into line contact at least in the width direction, a plane curve which can be a vertical cut including the axis of the side peripheral wall is formed. It must be pressed by using a pressing roller having an outer peripheral surface that is a rotation surface formed by rotating about an axis parallel to the center.

Therefore, in the case of an elliptical surface like a drum, the diameter of the outer circumference of the cross section of the container becomes smaller as it approaches the edge, and when the transfer sheet is wound, the contact length of the transfer sheet at the edge portion. There was a problem that the length was shortened and wrinkled. Therefore, it has been considered that a smooth transfer surface cannot be obtained for a curved surface such as a plane curved surface or an elliptical surface.

The present invention is a transfer sheet which solves the above-mentioned problems and is used for performing a smooth transfer on a container surface having a curved side surface of a side wall of a curved plane or an elliptical rotation surface. An object of the present invention is to provide a hologram transfer sheet in which a pattern is formed by hologram and which can be decorated with high quality.

[0006]

In order to solve the above problems, the present invention has a basic structure of a hologram transfer sheet in which a shrink film stretched in the same direction as the feed direction of the transfer sheet is laminated. And a release layer, a hologram film having a lower surface on which a hologram is formed and a vapor deposition layer deposited, and an adhesive layer.

As an embodiment of the transfer sheet, in addition to the above basic structure, a hologram film having a desired pattern for the vapor deposition layer and a structure in which base color printing is applied to the hologram film are adopted. .

Furthermore, the vapor deposition layer is thick-printed, or a pattern display portion is formed by the pattern and the base color printing portion, and the pattern display portion is continuous. Is added.

The transfer sheet to be transferred has a feature that it is a transfer sheet for decorating the peripheral surface of the side peripheral wall of a container having a plane curved surface of revolution as the side peripheral wall.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. First, the container A, which is the transfer target of the transfer sheet of the present invention, will be described.
As shown in FIG. 1, a container A is a drum-shaped container, and has a side peripheral wall 1 formed by cutting an elliptical surface of rotation in a cross section orthogonal to the axial direction, and an opening formed by upper and lower cut surfaces. Two
And bottom plate 3.

A pattern 4 is transferred and decorated on the peripheral surface of the side wall 1. As the picture pattern 4, a flower pattern is illustrated in the drawing, but the flower portion 5a and the surrounding portion 5b are formed by holograms, and the other portion is the base color printing portion 6. The design patterns 4 are positioned so as to be transferred to positions where the circumference of the container-side peripheral wall 1 is divided at equal intervals, and the design patterns 4 are connected by the base color printing section 6 and have a substantially constant width vertically. The display part a is formed.

The pattern on the pattern display portion a is a continuous pattern over the entire length of the transfer sheet B. When the pattern is transferred to the surface of the container side peripheral wall 1, the pattern at the transfer start end overlaps with the pattern at the transfer end end. As a result, the base color printing portion 6 at the end portion is covered, and a continuous pattern is displayed on the surface of the side peripheral wall 1.

The picture pattern 4 is not limited to a flower pattern, but may be any picture pattern formed by the hologram display portion and the base color printing portion. Alternatively, the entire peripheral surface of the side peripheral wall 1 may be formed of a hologram.

Next, the layer structure and manufacturing process of the transfer sheet B of the present invention will be described with reference to FIGS. As shown in FIG. 2, the transfer sheet B is a uniaxially stretched shrink film 10, a base film 11 and a release layer 12, a hologram film 13 whose lower surface is a hologram forming surface, and a pattern deposited on the lower surface of the hologram film 13. The vapor deposition layer 14 forming the pattern 4, the thick print layer 15, the base color print layer 16, and the adhesive layer 17 are sequentially laminated and configured. Then, the transfer layer B1 is constituted by the laminated body from the hologram film 13 to the adhesive layer 17.

The shrink film 10 is a uniaxially stretched shrink film made of PET as a material resin, and when the stretch direction is the transfer sheet B, the stretch film is stretched in the same direction as the feeding direction. . The stretching is basically uniaxial stretching, but may be performed by stretching at a constant ratio according to the curvature of the circumferential surface of the cross section of the container A side peripheral wall 1.

As the base film 11, a stretched film of heat-resistant PET is used, and the surface (the lower surface in the figure) of the base film 11 is coated with a commonly used easily peelable resin to form the release layer 12. Is formed. A heat-resistant resin is laminated on the surface (the lower surface in the figure) of the release layer 12, and unevenness 13a that forms interference fringes is formed on the lower surface by embossing to form a hologram film 13 on which a hologram forming surface is formed. Stacked. Next, the shrink film 10 is laminated by applying an adhesive on the upper surface of the base film 11 to obtain a laminate as shown in FIG.

Next, as shown in FIG. 3B, aluminum or another metal is vapor-deposited on the surface (lower surface in the figure) of the hologram film 13 to form a vapor deposition layer 14. Mask printing is performed on the surface (the lower surface in the figure) of the vapor deposition layer 14 according to a desired pattern, and the exposed vapor deposition layer 14 is dissolved with a solvent to form the vapor deposition layer 14 as shown in FIG. 3C. The hologram film 13 having a desired pattern is obtained.

Next, as shown in FIG. 3D, the vapor deposition layer 14 is subjected to thick printing to form a desired pattern.
Is formed, and base color printing is applied to the entire surface of the thick print layer 15 and the remaining hologram film 13 to form a base color print layer 16. Finally, an adhesive is applied to the surface of the base color print layer 16 to form the adhesive layer 17, and the transfer sheet B shown in FIG. 2 is completed.

In the transfer sheet B, the vapor deposition layer 14 is solved with a solvent while leaving a desired pattern, and the vapor deposition layer 14 is left.
Thick printing and base color printing were carried out, but as shown in FIG.
If the protective resin is applied to the surface of the sheet and the adhesive layer 17 is laminated thereon, a hologram transfer sheet having holograms formed on the entire surface of the sheet can be obtained.
Further, in the above process, the vapor deposition layer 14 is thick-printed to raise the desired pattern. However, the thick pattern may not be thick-printed to form a picture pattern composed of a flat hologram and a base color print layer.

Next, a method of transferring to the container A using the transfer sheet B will be described. FIG. 4 is a diagram showing a main part of the transfer device, in which 20 is an elastic pressing roller and 21 is a hot air heating device. The elastic pressing roller 20 has, as an outer peripheral surface, a rotation surface of a plane curve that appears in a vertical cutting plane including the axial center of the side peripheral wall 1 of the container A so as to make line contact with the surface of the outer peripheral wall 1 of the container A. Has been formed.

The hot-air heating device 21 changes the temperature of the hot air in the width direction so that the central part of the transfer sheet B is low and the peripheral part is high in temperature, and the temperature changes in accordance with the curvature of the cross section of the side peripheral wall 1. I am trying. Further, the transfer device includes a container holding device, a guide roller for the transfer sheet B, a pulling roller and the like (not shown). The container holding device holds the container A so as to be rotatable around its axis.

The transfer sheet B is supported between the side peripheral wall 1 of the container A and the elastic pressing roller 20, and is intermittently fed by the pulling roller every time it is transferred to the container A. At the time of transfer, the entire width of the transfer sheet B is sent via a guide roller so as to come into contact with the surface of the side peripheral wall 1 of the container A, and the elastic pressing roller 20 applies a constant pressure to the transfer sheet B.
Is pressed against the surface of the container A.

Before pressing, hot air is blown by the hot air heating device 21 so that the transfer sheet B is heated so that the peripheral portion has a high temperature and the central portion has a low temperature, so that the shrinkable film 10 has a shape of the surface of the container-side peripheral wall 1. While contracting and deforming, the transfer layer B1 is deformed into the same shape, and the adhesive layer 17 is adhered to the surface of the side peripheral wall 1.

Next, the transfer layer B1 is adhered to the surface of the container side peripheral wall 1 through the adhesive layer 17 by the pressing of the elastic pressing roller 20, and at the same time, the base film 11 and the release layer 1 are bonded together.
2 is separated from the transfer layer B1 and sent by a pulling roller. Then, a pattern in which a part of the picture pattern 4 is displayed as a hologram is transferred to the curved surface of the side peripheral wall 1 as a smooth surface.

Next, the transferred decoration will be described. A desired pattern is displayed on the surface of the side wall which is curved in the axial direction with a clear luster, and when thick printing is performed. Since it looks more raised than the base color print layer, it is possible to obtain an unprecedented decorative effect.

[0026]

Since the present invention is constructed as described above, it has the following effects. Since a shrink film is laminated on the base film of the hologram transfer sheet, and the heating of the transfer sheet is changed according to the curvature of the curved surface,
The transfer sheet was brought into close contact with the curved surface, and a high-quality decoration with a hologram pattern as a pattern was obtained.
