SOLUTION: A label base material 1 is formed by laminatingly forming, by vacuum deposition, an aluminum thin film layer 3, which has a thickness of 0.01 to 0.04μm capable of transmitting light, on a film 2 composed of polyester and the like, display print layers 4 having a predetermined display are formed on the side of one surface of the label base material 1, consealed display layers 6 are partially formed, via a transparent adhesive agent layer 5, in positions not overlapping with the display print layers 4 on the side of the other surface of the label base material 1, and this label is sticked on, for example, a tranparent container body by the adhesive agent layer 5. In this event, light transmissivity of peripheral parts of the consealed display layers 6 not overlapping with the aluminum thin film layer 3 is higher than light transmissivity of overlapping parts of the consealed display layers 6, and therefore it is made possible to see the consealed display layers 6 through the label base material 1 from either side of the front and the back depending on a viewing angle or a light condition.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label attached to a container or a package, which has a hidden display, and a container with such a label.

[0002]

2. Description of the Related Art As a product label, for example, an aluminum vapor deposition layer is formed on one side of a transparent or translucent film, an adhesive layer is formed on the aluminum vapor deposition layer, and a predetermined design is formed on the other side of the film. There is a so-called vapor-deposited label having a metallic gloss, which is formed by forming a printing layer. There is also a label adhesive layer having a display layer formed by printing a design different from that of the front print layer.

In the former case, even if the display of the print layer is visible from one side of the film, the display of the print layer cannot be seen from the other side of the film, whereas in the latter case, the display of the print layer is seen from the other side. The display viewed from the surface side and the display viewed from the other surface side are different, and the different types of display can strongly appeal the product to consumers.

[0004]

However, the display layer formed on the conventional adhesive layer is viewed from the back surface (adhesive layer side) of the label, not from the front side.

The problem to be solved by the present invention is a completely new label which has a metallic luster and allows the hidden display formed on the adhesive layer to be seen from either the front side or the back side depending on the viewing angle and light conditions. And to provide a container with this label.

[0006]

According to the first aspect of the present invention,
A label substrate composed of a transparent or semitransparent film in which a metal thin film layer having a translucent thickness is laminated, a display print layer formed on one surface side of the label substrate, and the other of the label substrate. It is characterized in that it has a hidden display layer formed on the surface side via an adhesive layer.

As described above, when the hidden display layer is formed on the other surface side of the label base material via the adhesive layer, the hidden display layer peripheral portion where the hidden display layer is not superposed on the metal thin film layer of the label base material. The light transmittance of the hidden display layer is higher than the light transmittance of the overlapping portion of the hidden display layer, and the hidden display layer can be viewed from either the front side or the back side through the label substrate depending on the viewing angle and light conditions. Therefore, the characteristics of the product can be further appealed to the consumer, and the interest of the consumer for the product can be further aroused.

Further, as described in claim 2, the label according to claim 1 may be adhered to the container body by the adhesive layer to form a labeled container.

BEST MODE FOR CARRYING OUT THE INVENTION

(First Embodiment) A first embodiment of the present invention will be described with reference to FIGS.

FIG. 1 shows a label according to the present invention. In FIG. 1, 1 is a label base material having a thickness of 10 to 100 μm.
A transparent film 2 made of polyester, polypropylene or the like, and an aluminum thin film layer 3 which is a metal thin film layer laminated on one surface side of the film 2,
The aluminum thin film layer 3 is formed by vacuum vapor deposition of aluminum to have a thickness of 0.01 to 0.04 μm, preferably 0.02 to 0.035 μm, which is a thickness capable of transmitting light.

At this time, when the thickness of the aluminum thin film layer 3 is thinner than this range, the mirror-specific light-reflecting property of light and the silver-white luster are lost, and conversely when it is thicker than this range. Since the light transmittance of the aluminum thin film layer 3 becomes too small, the light transmittance is lost.
The thickness is preferably within the above range.

Further, 4 is a display print layer having a predetermined display, which is formed on a part of the other surface side of the film 2, and 5 is a transparent or semitransparent adhesive layer, which is an aluminum thin film layer 3
The hidden display layer 6 is formed on one surface of the adhesive layer 5, and is partially formed at a position not overlapping the display print layer 4 on one surface of the adhesive layer 5, for example, with a printing ink containing fine aluminum powder. Since the light transmittance of the portion around the hidden display layer 6 where the hidden display layer 6 is not overlapped with the thin film layer 3 is higher than the light transmittance of the overlapped portion of the hidden display layer 6,
Depending on the viewing angle and light conditions, the hidden display layer 6 can be viewed through the label substrate 1 from either the front or back side.

In this case, the hidden display layer 6 may use an ink containing a pearl pigment, in addition to the above-mentioned printing layer formed from a printing ink containing fine aluminum powder.

By the way, in the case of producing such a label, usually, the aluminum thin film layer 3 is first laminated on the film 2 to form the label substrate 1, and the aluminum thin film layer 3 of the label substrate 1 is further coated with an adhesive layer. 5, the release paper is releasably adhered to the adhesive layer 5 to form a so-called tack base paper. This tack base paper is generally wound around a take-up roll. For example, while the display print layer 4 is formed on the film 2 of the tack base paper fed out from the take-up roll, the release paper is once released to expose the adhesive layer 5. Then, after forming the hidden display layer 6 on the exposed adhesive layer 5, the release paper is laminated again, and the label having the hidden display is obtained by appropriately punching and cutting.

When such a label is actually used for a product, the release paper on the back side of the label is peeled off to expose the adhesive layer 5, and the transparent layer as shown in FIGS. Alternatively, a label is adhered to the container body 8 made of translucent glass, synthetic resin or the like, which is filled with a transparent liquid such as cosmetics or beverages, by the adhesive layer 5 to obtain a labeled container having a hidden display. .

In such a labeled container, when the container body 8 is held from the label side to light, a hidden display is formed in which the portion where the hidden display layer 6 is not overlapped is formed on the aluminum thin film layer 3 (FIG. 2). You can see the broken line inside).

Therefore, by setting the display on the hidden display layer 6 of the label to, for example, a trademark or a logo, it becomes possible to read the product name and other information related to the product by letting it through through the light. This product can make a deeper impression on consumers.

Further, if the liquid in the container body 8 is made opaque, the hidden display cannot be seen because the light hardly penetrates from the inner surface side when the liquid is filled, but the container body is not visible. Since the watermark can be seen only when 8 becomes empty, a product with a lottery can be provided by changing the hidden display to a lottery display such as "hit" or "off".

Further, the presence of the hidden display makes it possible to determine whether the product with this label is genuine or not, and therefore the label having this hidden display can be used for preventing forgery of the product.

Further, since the hidden display layer 6 is formed by printing with the ink containing the fine aluminum powder of the same color as the aluminum thin film layer 3, the aluminum thin film layer 3 and the hidden display layer 6 have substantially the same color. Even if the container body 8 is viewed from the side opposite to the label, the watermark portion cannot be easily identified, which is preferable.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIG. still,
4, the same reference numerals as those in FIG. 1 denote the same or corresponding parts.

As shown in FIG. 4, a hidden display layer 6 is formed on the film 2 side of the label substrate 1 with an adhesive layer 5 interposed therebetween.
Aluminum thin film layer 3 which is a metal thin film layer of the label substrate 1
A label is formed by laminating a surface protective film 13 having a display print layer 12 formed on the inner surface via an adhesive layer 11 on the side. At this time, the hidden display layer 6 is formed so that the display print layer 12 does not cover the entire hidden display layer 6 and the display print layer 12 and the hidden display layer 6 do not overlap each other.

Therefore, even if the hidden display layer 6 is formed on the metal thin film layer of the label substrate 1 on the side opposite to the case of the above-described first embodiment (see FIG. 1), the first
Of course, it is possible to obtain the same effect as that of the above embodiment.

In each of the above embodiments, the case where the film 2 is transparent has been described, but the present invention can be similarly implemented even when the film 2 is semitransparent.

In each of the above embodiments, the case where the metal thin film layer is the aluminum thin film layer 3 formed by vacuum evaporation of aluminum has been described, but a metal such as silver or tin may be used instead of aluminum. Of course, the forming method may be sputtering or the like other than the above-mentioned vacuum vapor deposition, and may be formed by a printing ink containing fine aluminum powder.

Further, the hidden display layer 6 is not limited to the above-mentioned one, and it is needless to say that it may be formed by a transfer foil (hot stamp). When it is formed by printing, white, black, other than silver, Even if it is blue, red, or yellow, the same effect can be obtained when viewed from the surface.

Further, as the adhesive layer 5, a heat-sensitive adhesive such as hot melt or delayed tack can be used in addition to the pressure-sensitive adhesive for laminating the release paper.

[0028]

As described above, according to the invention of claim 1, the other side of the label substrate made of a transparent or semitransparent film in which a metal thin film layer having a translucent thickness is laminated. Since the hidden display layer is formed via the adhesive layer, the light transmittance of the peripheral portion of the hidden display layer where the hidden display layer is not overlapped with the metal thin film layer of the label base material is equal to the light transmittance of the overlapped portion of the hidden display layer. Depending on the viewing angle and light conditions, it is possible to provide a label that allows the hidden display layer to be viewed from either the front or back side through the label base material. It is possible to further appeal the characteristics of the item to the consumer, and it is possible to further arouse the consumer's interest in the product.

Further, as described in claim 2, by adhering such a label to the container body with an adhesive layer, a container with a watermark can be provided, and the watermark can be a trademark, a logo or the like. By storing the information, the product name and other information related to the product can be read from the watermark, and the watermark makes it possible to make a deep impression on the consumer.
