JP 2000-318290 A

It is an object of the present invention to create a discrimination function related to a counterfeit product using a hidden structure or a pattern that is difficult to understand or imitate by a third party using a laminated structure mainly composed of a synthetic resin. To do.

The main configuration of the present invention related to the means for solving the above technical problem is:
In a laminated structure, two base layers made of synthetic resin are laminated together, and a labeling layer made of a material having a lower X-ray transmittance than these base material layers is laminated between both base material layers. And
At least one substrate layer is opaque,
The labeling layer is configured to have a concavo-convex portion that is partially bent into a concavo-convex shape.

In the above configuration, the uneven portion of the marker layer exhibits a function as a so-called hidden character or pattern, and at least one of the base material layers is made opaque so that the marker layer cannot be seen from the outside. be able to.
On the other hand, the use of the fact that the X-ray transmittance of the marker layer is low, and the transmission distance of the X-ray in the marker layer changes along the concavo-convex structure, and the amount of X-ray transmission changes. If necessary, a device that can detect a difference in the X-ray transmittance in an object such as an X-ray transmission device or a CT device (hereinafter referred to as an X-ray transmission device) is used to make the unevenness without destroying the product. The presence or absence of hidden characters or designs formed by the part can be confirmed,
By disposing such a laminated structure in a packaging container or the like, a discrimination function related to a counterfeit product can be imparted to the product.

In addition, both base material layers can also be made from the same synthetic resin according to the objective, and can also be made from a different synthetic resin.
Moreover, whether one of the base material layers is opaque or whether both of the base material layers are opaque can be selected according to the usage mode of the laminated structure, so that both sides of the laminated structure are exposed to the outside. Of course, in both applications, both substrate layers are opaque.
Further, by making both the base material layers opaque, for example, even when the packaging container as a laminated structure is disassembled, the presence of the marker layer is hidden, so that the appearance of counterfeits can be prevented more reliably. It becomes possible.

  Another configuration of the present invention is that the marking layer is formed by laminating the labeling layer in a planar shape selected from characters, symbols, designs, and patterns in the main configuration described above, and an uneven portion formed by an X-ray transmission device or the like. Confirmation can be easily achieved.

  Still another configuration of the present invention is that, in the above main configuration, the labeling layer is made of a material in which an inorganic filler or an inorganic pigment is dispersed in a synthetic resin.

The material of the labeling layer is not particularly limited within the category that the X-ray transmittance is smaller than both base material layers, but the labeling layer is made of a material in which an inorganic filler or an inorganic pigment is dispersed in a synthetic resin according to the above configuration. By doing so, the X-ray transmittance of the marker layer can be made smaller than that of the two substrate layers without significantly degrading the adhesiveness between the two substrate layers and the marker layer and the flexibility of the laminated structure by the lamination of the marker layers. it can.
In particular, if the same synthetic resin is used for both the base material layer and the labeling layer, the three layers can be laminated in a state where they are securely bonded in a heat-welded state.

  In order to make both the base material layers opaque, a small amount of inorganic filler or inorganic pigment may be dispersed in both base material layers themselves. Disperse the inorganic pigment.

  Still another configuration of the present invention is that in the main configuration described above, the marker layer is a coating layer.

The above configuration relates to the method of laminating the marker layer, but the X-ray transmittance of the coating layer can be reduced by using a paint in which an inorganic filler or an inorganic pigment having a low X-ray transmittance is dispersed. The marker layer can be easily laminated by painting.
Then, unevenness is formed by changing the layer thickness on one surface of one base material layer, and a coating layer that becomes a marker layer is formed along the unevenness as described above. A laminated structure can be produced by covering with a base material layer.

  Still another configuration of the present invention is that in the above main configuration, the laminated structure is a label, and a label that is a laminated structure having a discrimination function related to a counterfeit product is attached to a packaging container or the like. The discrimination function related to the counterfeit product can be easily given to the product.

  Still another configuration of the present invention is that, in the main configuration described above, the laminated structure is a tube body in which the marker layer is made of aluminum foil or aluminum sheet and is laminated over the entire peripheral surface.

The tube body with the above structure is one in which a label layer made of aluminum foil or aluminum sheet is laminated over the entire circumference, and by using this tube body as a body part of a tube container, gas barrier properties, fragrances, etc. Since the function of preventing the volatilization of the components is sufficiently exhibited, it is possible to provide a tube container that can effectively suppress the deterioration of the contents and that has the discrimination function related to the counterfeit product.
In addition, the tube body as described above is formed into an uneven shape on an aluminum foil or aluminum sheet by pressing or the like, and a base layer made of a synthetic resin is laminated or overcoated on both sides to form a sheet piece laminated structure. It can be made by winding the sheet piece and sealing both ends.

Since the present invention has the above-described configuration, the following effects can be obtained.
That is, in the laminated structure having the main configuration of the present invention, the uneven portion of the marker layer exhibits a function as a so-called hidden character or design,
By making at least one of the base material layers opaque, it cannot be seen from the outside of the marker layer and the uneven portion, and on the other hand, the X-ray transmittance of the marker layer is low, and the uneven portion is along the uneven structure. An apparatus capable of detecting a difference in X-ray transmittance in an object, such as an X-ray transmission apparatus or a CT apparatus, by utilizing the fact that the transmission distance in the X-ray labeling layer changes and the X-ray transmission amount changes. If necessary, it is possible to confirm the presence or absence of hidden characters or designs formed by uneven parts without destroying the product, and by imposing such a laminated structure on a packaging container etc. The discrimination function related to the product can be given to the product.

It is a perspective view which shows the tube container which uses the tube body of 1st Example of the laminated structure of this invention. It is a perspective view which shows the layer structure of the tube container of FIG. It is a top view which shows the label of 2nd Example of the laminated structure of this invention. It is sectional drawing which shows the layer structure of the label of FIG.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments of the invention will be described with reference to the accompanying drawings.
1 and 2 are views for explaining a tube container using a tube body which is a first embodiment of the laminated structure of the present invention, FIG. 1 is a perspective view, and FIG. 2 is a perspective view showing the layer structure thereof. It is a figure and the cross-sectional structure is shown by this side.
This tube container 1 uses a cylindrical tube body 2t made by winding a sheet piece and sealing both end portions as a barrel portion 2, and is attached to one end of the barrel portion 2 by injection molding or compression molding. The head portion 3 is integrated, and the content is filled from the remaining end, and the end is a flat bottom seal portion 4.

As shown in FIG. 1 or 2, the layer structure of the peripheral wall of the tube body 2 t that forms the body portion 2 of the tube container 1 includes an outer base material layer 11 and an inner base material layer 12 that are laminated together. The marker layer 13 is laminated over the entire circumferential surface.
FIG. 1 shows a state in which a part of the peripheral wall is cut out, and further, a part of the inner base material layer 12 is peeled and removed at the cut out part.

  In this embodiment, the outer base layer 11 is made of a low density polyethylene resin, the inner base layer 12 is made of a high density polyethylene resin, and the outer base layer 11 has 3 parts by weight with respect to 100 parts by weight of the resin. Titanium white fine powder is mixed to make it white opaque.

  The marking layer 13 is made of a thin sheet made of aluminum and has a concavo-convex portion S that is partially bent into a concavo-convex shape by a press process. Is formed.

  And since the outer base material layer 11 is white and opaque in the normal state, the tube body 2t of the present embodiment cannot visually recognize the marker layer 13 and the concavo-convex portion S from the outside. The low X-ray transmittance and the X-ray transmission distance in the marker layer 13 change along the concavo-convex structure in the concavo-convex portion S as shown by the three dotted arrows X1, X2, and X3 in FIG. Using the change in the amount of transmitted X-rays, confirm the presence or absence of hidden characters A and B by the concavo-convex portion S without destroying the product, if necessary, using an X-ray transmission device or the like. Can do.

  For example, when the three dotted arrows X1, X2, and X3 in FIG. 2 are compared, the transmission distance of the X-ray labeling layer 13 is larger at the position of X2, compared to the positions of X1 and X3. The amount of transmission is reduced, and as a result, the character A can be detected by an X-ray transmission device or the like.

Next, FIGS. 3 and 4 are for explaining a label which is a second embodiment of the laminated structure of the present invention, FIG. 3 is a plan view thereof, and FIG. 4 is a sectional view showing a layer structure.
As shown in FIG. 2, the label 20 has a layered structure in which a labeling layer 23 is laminated between an outer base material layer 21 and an inner base material layer 22 that are laminated together. Further, an adhesive layer 26 is laminated on the lower side of the inner base layer 22, and stylized letters a, b, c, d, e are formed on the upper side of the outer base layer 21 for decoration. The decorative print layer 24 is laminated, and a transparent protective layer 25 is laminated so as to cover the decorative print layer 24.
In this embodiment, both the outer substrate layer 21 and the inner substrate layer 22 are made of a stretched polypropylene resin film that is colored so as to be opaque.

  The marker layer 23 is a coating layer coated with a paint in which an inorganic pigment having a low X-ray transmittance is dispersed, and the upper surface of the inner base material layer 22 is formed in an uneven shape by changing the layer thickness. The laminated structure having the concavo-convex portion S can be produced by forming a coating layer that becomes the marking layer 23 along the concavo-convex, and further covering the coating layer with the outer base material layer 21. The uneven portions S form stylized characters A and B that are hidden characters.

In the label 20 of the present embodiment, the outer and inner base layers 21 and 22 are opaque in a normal state. Therefore, as shown in the plan view of FIG. Although it cannot be visually recognized from, like the tube body 2t of 1st Example mentioned above,
Utilizing the fact that the X-ray transmittance of the marker layer 23 is low and that the unevenness portion S changes the X-ray transmission distance and the X-ray transmission amount in the marker layer 23 along the uneven structure, The presence or absence of A and B characters, which are hidden characters by the concavo-convex portion S, can be confirmed as necessary by an X-ray transmission device or the like.

As mentioned above, although the structure of this invention and its effect were demonstrated along the Example, the laminated structure of this invention is not limited to the said Example.
For example, the laminated structure of the present invention can be added with a layer such as a decorative layer or a gas barrier layer as necessary. Further, the laminated structure is not limited to the tube body and the label of the above-described embodiment, and can be formed in various forms.

Further, in the above embodiment, in order to reduce the amount of X-ray transmission, the marker layer is made of a thin sheet made of aluminum or a paint mixed with an inorganic pigment. However, an inorganic filler or an inorganic pigment is also added to the synthetic resin. Means such as a mixed resin material or a hot stamp film in which a metal foil layer is laminated can also be employed.

As described above, the laminated structure of the present invention has a discrimination function related to a counterfeit product based on hidden characters and patterns in a method that is difficult to understand or imitate by a third party using the difference in the transmittance of X-rays. It is expected to be used widely as a countermeasure against counterfeit products.
