Description

The present invention relates to a film with a hologram pattern and a container with a hologram pattern. The film with a hologram pattern particularly relates to a film with a hologram pattern that can be used for containers or packages that contain beverages or foods.

In recent years, for the purpose of decoration, there has been proposed a container, package or other object provided with a hologram pattern on the outer surface. This hologram pattern is a pattern of interference fringes recorded in a plane, which is formed into a fine uneven shape forming an embossed shape or a relief shape, and is formed directly on the outer surface of an object or separately formed The method of sticking to the outer surface of a container is examined.

As a method of directly forming a hologram pattern on the outer surface of a container, a method in which a metal plate on which a concavo-convex hologram pattern is formed is engaged with the surface of a container as an object has been proposed. In addition, as a method of separately forming the hologram pattern, after the concave and convex hologram pattern formed on the matrix made of a metal thin film is pressure-molded into a thermoplastic resin or an ultraviolet curable resin, and the resin is cured, The thing adhering to a container outer surface is proposed (patent documents 1-2).

In these hologram patterns, the hologram pattern is the outermost layer without forming a protective layer on the outside. This is because if the uneven pattern is filled with a material having the same refractive index as the material on which the hologram pattern is formed, the hologram effect may be lost.
Japanese Patent Laid-Open No. 11-268746 JP 2000-128176 A

However, if the object is a container or other object that is placed under refrigeration, refrigeration, or water during storage, transportation, store display or other production-to-consumption periods, holograms The pattern may be lost. That is, if the uneven pattern is buried on the hologram pattern due to the attachment of water droplets due to condensation or water for cooling, when the refractive index of water and the material forming the hologram pattern is close, the hologram The pattern disappears and the hologram effect cannot be expressed.

Moreover, there is a possibility that the hologram pattern may be lost when a person who handles the object or a consumer who has purchased the object touches the hologram pattern. This occurs when the uneven pattern is filled with sebum from the hand of a consumer or consumer, sweat from the hand, water or other liquid on the hand.

In order to solve such a problem, it is known to form a protective layer on the hologram pattern using vapor deposition or other means. However, for example, in the case of vapor deposition, since it is necessary to perform the film forming process in a vacuum state, the production efficiency is lowered and the production cost is increased, which may lead to an increase in the price of containers and other objects.

Therefore, the present invention can prevent the hologram pattern from disappearing due to water droplets, sebum, sweat on the hologram pattern while suppressing a decrease in production efficiency and an increase in production cost. An object of the present invention is to provide a film with a hologram pattern and a container with a hologram pattern capable of exhibiting a hologram effect in the period from production to consumption. Accordingly, an object of the present invention is to provide a film with a hologram pattern and a container with a hologram pattern that can visually recognize a hologram pattern without selecting the state and conditions of storage, transportation, and display of an object with a simple configuration. There is to do.

In order to solve the above-mentioned problems, the film with a hologram pattern of the present invention includes a hologram pattern forming layer on which a concavo-convex hologram pattern is formed, and at least a part of the hologram pattern has a gap between the hologram pattern and the hologram pattern. The cover film is fixed so as to have.

In the film with a hologram pattern of the present invention, it is preferable that the air gap is formed at least between the concave portion of the hologram pattern.

In the film with a hologram pattern of the present invention, the hologram pattern may include a non-display portion in which the hologram pattern is filled with a fluid material.

In the film with a hologram pattern of the present invention, the non-display portion may be filled with an adhesive material, and the cover film may be bonded and fixed to the non-display portion with an adhesive material.

In the film with a hologram pattern of the present invention, the cover film is preferably adhered and fixed to an area where the hologram pattern is not formed by an adhesive material.

In the film with a hologram pattern of the present invention, the cover film can be disposed so as to cover the entire surface of the hologram pattern.

In the film with a hologram pattern of the present invention, the hologram pattern can be formed on a hologram pattern forming layer as a substrate film.

In the film with a hologram pattern of the present invention, the adhesive material can be a self-curing material.

The hologram pattern-equipped container of the present invention includes a hologram pattern forming layer in which a concavo-convex hologram pattern is formed, and a cover film fixed so as to have a gap between the hologram pattern and at least a part of the hologram pattern; A film with a hologram pattern having the above is provided on the outer surface.

In the container with hologram pattern of the present invention, the film with hologram pattern is preferably fixed to the outer surface of the container by a cover film.

In the container with a hologram pattern of the present invention, a reflective layer can be provided on the cover film.

According to the present invention, it is provided with a hologram pattern forming layer on which a concavo-convex hologram pattern is formed, and at least a part of the hologram pattern has a gap between at least a recess and the cover film is fixed. Since the cover film is provided through the gap in the portion where the hologram pattern is to be left, even if water droplets, sebum, or sweat adheres to the cover film, it does not adhere to the hologram pattern. Thereby, it is possible to prevent the hologram pattern from disappearing during storage, transportation, store display, and other periods from production to consumption. In addition, the hologram pattern can be filled with a fluid material (for example, adhesive material, paint, ink) in a portion where the hologram pattern is to be erased. Therefore, the portion where the hologram pattern is desired to remain and the portion where the hologram pattern is desired to be erased can be set with an arbitrary shape and pattern, and a hologram pattern with higher decorativeness can be formed.

Hereinafter, a film with a hologram pattern and a container with a hologram pattern according to an embodiment of the present invention will be described in detail with reference to the drawings.

The hologram pattern-attached film 10 according to the present embodiment is a sheet-like, roll-film-like, or label-like film that is used by being placed on the outer surface of a container, package, or other object that contains a beverage or food. is there. Examples of the object include a metal can, a plastic container and package, a paper container and package, and a container containing aluminum. Here, examples of the container include a pouch (flexible package), a cup, a can, and a plastic bottle.

The film with a hologram pattern 10 includes a hologram pattern forming layer 12 on which a concavo-convex hologram pattern 13 is formed, and a cover film 15 is fixed so as to have a gap 17 in at least a part of the hologram pattern 13. Below, the detailed structure of each layer is demonstrated along the order of a manufacturing process. In the following description, an embodiment in which a film with a hologram pattern is applied to a container will be described as an example. However, the film with a hologram pattern according to the present invention can be applied to an object other than a container.

(1) Hologram pattern formation FIG. 1: is sectional drawing which shows the layer structure in each manufacturing process of the film 10 with a hologram pattern which concerns on this embodiment, and the container 30 with a hologram pattern.
In the hologram pattern forming step, first, the hologram pattern forming layer 12 is formed on the substrate 11 (FIG. 1 (a-1)) (FIG. 1 (a-2)). The hologram pattern forming layer 12 may be formed on the entire surface of the substrate 11 or may be formed on only a part thereof.

The substrate 11 can be made of a permeable material or an aluminum foil or other metal foil. Examples of the material having permeability include PET (polyethylene terephthalate) film, nylon (trademark) film, OPP (stretched polypropylene) film, and other resin films. These resin films or aluminum foils are preferably formed in advance by printing (for example, gravure printing). Moreover, the base material 11 can use any form of a sheet form or a roll shape according to the kind and specification of the container which are the formation object of a hologram pattern.

As the hologram pattern forming layer 12, for example, a thermoplastic resin, an ultraviolet curable resin, or a self-curable resin can be used. The film formation can be performed, for example, by transfer using a coating roll, spraying by spraying, or spin coating.

Subsequently, a concavo-convex hologram pattern 13 having convex portions 13a and concave portions 13b is formed on the outer surface 12a of the hologram pattern forming layer 12 (FIG. 1 (a-3)). The hologram pattern 13 is formed by press-molding a concavo-convex hologram pattern formed on a matrix on the hologram pattern forming layer 12 and then curing it by a method corresponding to the material. The hologram pattern 13 may be formed over the entire surface of the hologram pattern forming layer 12 or may be formed only on a part thereof. In FIG. 1, for convenience of explanation, the hologram pattern forming layer 12 is displayed as a simple one consisting of only two types of convex portions 13 a and concave portions 13 b.

Here, the matrix is formed as follows, for example. That is, the laser interference film is exposed to a dry plate coated with a photoresist to form a concave / convex resist pattern corresponding to the density of the interference fringes, and then a metal is vapor-deposited to form a thin film to have conductivity. And nickel plating on it. Next, by peeling off the plating layer, a mother die in which a fine concavo-convex hologram pattern is precisely transferred onto nickel is formed.

(2) Attaching the cover film Next, the cover film 15 is fixed so as to cover the hologram pattern 13. Covering the hologram pattern 13 with the cover film 15 prevents water droplets, sebum, and sweat from adhering to the cover film 15, so that it does not adhere to the hologram pattern 13. The hologram pattern 13 can be prevented from disappearing during the period from production to consumption.

The cover film 15 is preferably fixed by adhesion using an adhesive layer 14 made of a fluid adhesive material. As shown in FIG. 2A, the adhesive material constituting the adhesive layer 14 fills a part of the hologram pattern 13 or, as shown in FIG. It can apply | coat to the part in which 13 is not formed. Here, FIG. 2 is a plan view schematically showing the relationship between the hologram pattern 13 and the adhesive layer 14 in the hologram pattern-attached film 10 according to the present embodiment. FIG. 2B shows a case where the adhesive layer 14 is formed on the outer side of the hologram pattern 13.

As shown in FIG. 2A, when the adhesive material constituting the adhesive layer 14 is applied to a part of the hologram pattern 13, the applied portion of the hologram pattern 13 disappears. That is, a non-display portion where no hologram pattern is displayed can be formed on the hologram pattern forming layer 12. On the other hand, if the adhesive material which comprises the contact bonding layer 14 is applied so that it may not cover the hologram pattern 13 like FIG.2 (b), all the hologram patterns 13 can be displayed.

As described above, since the non-display portion can be set at an arbitrary position and range by forming the adhesive layer 14, the portion where the hologram pattern 13 is to be left and the portion where the hologram pattern 13 is to be deleted are set in an arbitrary shape and pattern. It is possible to form a hologram pattern with higher decorativeness.

As an adhesive material constituting the adhesive layer 14, for example, a thermoplastic resin, an ultraviolet curable resin, or a self-curable resin can be used. The adhesive layer 14 can be formed by, for example, transfer using a coating roll or spraying using a spray.

The layer thickness of the adhesive layer 14 is preferably such that there is a gap between the cover film 15 to be later bonded onto the adhesive layer 14 and at least the concave portion 13b, and between the cover film 15 and the convex portion 13a. Also, it is better that the voids are generated. With such a film thickness, the concavo-convex shape of the hologram pattern 13 is not filled with the cover film 15 and the hologram pattern 13 is not lost.

The cover film 15 can be fixed by a method other than the bonding by the adhesive layer 14 (for example, fusion of the cover film 15 and the base material 11 or the hologram pattern forming layer 12 or fixing by a fixing jig). In this case, with respect to the hologram pattern 13, the non-display portion can be formed by a fluid material (for example, paint, ink) other than the adhesive material.

The cover film 15 can be made of a transparent material (for example, a PET film, a nylon film, an OPP film, or other resin film). If the hologram film 13 can be covered, the shape and area can be arbitrarily set. Can be determined. For example, as shown in FIG. 3 (a), the entire top surface of the substrate 11 can be covered, but as shown in FIG. 3 (b), the substrate 11 is arranged only on the portion covering the hologram pattern 13. You can also Here, FIG. 3 is a plan view schematically showing the relationship between the hologram pattern 13 and the cover film 15 in the hologram pattern-attached film 10, and (a) covers the entire substrate 11 with the cover film 15. (B) is a figure which shows the case where only the hologram pattern 13 of the base material 11 and its periphery are covered with the cover film 15. FIG. In FIG. 3, the display of the adhesive layer 14 is omitted. The cover film 15 is preferably formed in advance by printing (for example, gravure printing). In this case, the hologram pattern can be visually recognized only through an unprinted portion.

The formation pattern of the adhesive layer 14 can be arbitrarily selected according to the setting of the non-display portion, the adhesive strength, and other settings. That is, as shown in FIG. 2, the portion (display unit) for displaying the hologram pattern can be left uniformly in a certain range around the window (display portion). It is possible to select a grid pattern as shown in FIG. 4 or a dot pattern as shown in FIG. Here, FIG. 4 is a plan view schematically showing a formation pattern of the adhesive layer 14 in the film 10 with a hologram pattern, in which (a) shows a case where it is formed in a lattice shape, and (b) is a dot. It is a figure which shows the case where it forms in a shape. Note that the patterns shown in FIGS. 4A and 4B are illustrated for convenience of explanation, and instead of this, characters (for example, company names, product names), designs, and other arbitrary patterns are formed. be able to.

The cover film 15 is placed on the adhesive layer 14 (FIG. 1 (a-4)) applied and formed on the hologram pattern 13 or the substrate 11, and the cover film 15 is applied by the adhesive force of the adhesive layer 14. It fixes (FIG. 1 (a-5)). In the process of placing and bonding the cover film 15, it is preferable to apply a certain tension to the cover film 15 in order to maintain a gap between the hologram pattern 13 and the cover film 15. The film 10 with a hologram pattern is formed by the above process.

(3) Container sticking Finally, the hologram pattern-attached film 10 is stuck and fixed to the outer surface of the container 21 by the adhesive force of the adhesive layer 22. Any adhesive material can be used for the adhesive layer 22, but curing is not completed during the operation of attaching the hologram pattern-attached film 10 to the container 21, and it is cured quickly after the application operation. What can be made is preferable. Examples of such an adhesive material include thermosetting, thermoplastic, and self-curing materials. The surface 31 of the hologram pattern-equipped container 30 (the surface of the cover film 15 attached to the container 21) is provided with slipperiness and other physical properties necessary for the manufacture of the container, filling of the contents, distribution and other processes. For the purpose of imparting gloss for improving decorativeness, a transparent or semi-transmissive material (for example, paint or ink) may be applied over the entire surface or a part thereof.

With the configuration as described above, the following effects (1) to (3) are achieved according to the above embodiment.
(1) Even if water droplets, sebum, and sweat adhere to the cover film 15, the possibility of reaching the hologram pattern 13 is extremely low. Thereby, it is possible to prevent the hologram pattern 13 from disappearing during storage, transportation, store display, and other periods from production to consumption.
(2) In a portion where the hologram pattern 13 is to be erased, this can be realized by filling the hologram pattern 13 with an adhesive material, paint, ink or other fluid material. Therefore, a portion where the hologram pattern 13 is desired to be left and a portion where the hologram pattern 13 is desired to be deleted can be set with an arbitrary shape and pattern, and a hologram pattern with higher decorativeness can be formed.
(3) Since the effects of (1) and (2) can be realized with a simple configuration, a decrease in manufacturing efficiency and an increase in manufacturing cost can be suppressed.

A modification will be described below.
In the above-described embodiment, the hologram pattern formed on the base material 11 is configured to be sandwiched between the cover film 15 with a gap, but by changing the direction in which the base material 11 is attached to the container 21, A container with a hologram pattern having a simpler configuration that does not require the film 15 can be realized. Such a container with a hologram pattern will be described below with reference to FIG.

Fig.5 (a) is sectional drawing which shows the structure of the container 60 with a hologram pattern which concerns on a 1st modification. In addition, about the structure similar to the above-mentioned embodiment, the same code | symbol is attached | subjected and the detailed description is abbreviate | omitted.
For the base material 11, for example, a resin film (for example, PET film, nylon film, OPP film) is used as a material having transparency. This base material 11 can be formed in advance by printing (for example, gravure printing). In this case, in the final container 60 with a hologram pattern, the hologram pattern can be visually recognized only through a portion where the adhesive layer 14 is not applied to the hologram pattern 13.

The container 60 with a hologram pattern is formed as follows. First, a film with a hologram pattern without a cover film is formed by the same steps as (a-1) to (a-4) in FIG. This hologram pattern-attached film is affixed to the container 21 by the adhesive layer 14 so that the base material 11 is disposed outside. A desired pattern (for example, a character or a design) can be formed on the surface 21a of the container 21 by a known printing method (for example, offset printing, letterpress, or gravure printing). By forming the pattern in the container 21 in this way, the reflected light changes from part to part depending on the color and shade of the design to be printed, so that the decorativeness can be further improved.

Further, when a material having a metallic luster is used as the surface 21a of the container 21, a lot of reflected light can be obtained in the final container 60 with a hologram pattern, so that the visibility of the hologram pattern is further improved. be able to. In addition, the surface 61 (outer surface of the base material 11) of the container 60 with a hologram pattern is used for the manufacture of the container, the filling of the contents, the distribution and other processes, and the addition of slipperiness and other physical properties, and the improvement of the decoration. For the purpose of imparting gloss, a transparent or semi-transmissive material (for example, paint or ink) may be applied over the entire surface or partially.

FIG.5 (b) is sectional drawing which shows the structure of the container 70 with a hologram pattern which concerns on a 2nd modification.
In FIG. 5 (a), when the surface 21a of the container 21 does not have a metallic luster, the reflected light from the final container with the hologram pattern is reduced. Visibility is reduced. On the other hand, the second modification shown in FIG. 5B can increase the reflected light from the container with the hologram pattern even when the surface 21a of the container 21 does not have a metallic luster. Thus, the visibility of the hologram pattern is improved, and a container with a hologram pattern with higher decorativeness is realized. The details will be described below. In addition, about the structure similar to the above-mentioned embodiment, the same code | symbol is attached | subjected and the detailed description is abbreviate | omitted.

For the base material 11, for example, a resin film (for example, PET film, nylon film, OPP film) is used as a material having transparency. This base material 11 can be formed in advance by printing (for example, gravure printing). In this case, in the final container 70 with a hologram pattern, the hologram pattern can be visually recognized only through a portion where the adhesive layer 14 is not applied to the hologram pattern 13.

The container 70 with a hologram pattern is formed as follows. First, a film with a hologram pattern without a cover film is formed by the same steps as (a-1) to (a-4) in FIG. Next, the cover film 15 is affixed using the contact bonding layer 14 similarly to (a-5) of FIG. Here, it is preferable that a reflection layer (not shown) is formed on at least a part of the surface 15a or the back surface 15b of the cover film 15 on the hologram pattern 13 side to form a reflection surface. As the cover film provided with the reflective layer, a transmissive film (for example, PET, nylon, OPP) coated with an aluminum thin film by vacuum deposition, sputtering, or other methods, aluminum foil, or other metal foil can be used. Further, the cover film 15 is formed in advance by printing (for example, gravure printing), so that the reflected light changes for each part depending on the color and shade of the design to be printed.

Finally, an adhesive is applied to the back surface 15b of the cover film 15 to form an adhesive layer 22, and the adhesive layer 22 is affixed to the surface 21a of the container 21 to obtain a container 70 with a hologram pattern.
The surface 71 of the hologram pattern-equipped container 70 (the outer surface of the base material 11) is provided with slipperiness and other physical properties necessary for the manufacture of the container, filling of the contents, distribution and other processes, and improvement of the decoration. For the purpose of imparting gloss, a transparent or semi-transmissive material (for example, paint or ink) may be applied over the entire surface or partially.

Although the present invention has been described with reference to the above embodiment, the present invention is not limited to the above embodiment, and can be improved or changed within the scope of the purpose of the improvement or the idea of the present invention.
