Description

  The present invention relates to a multiple wall structure, and more particularly to a multiple wall structure configured to exhibit a discrimination function related to counterfeits.

  In recent years, with the internationalization of distribution, sophisticated counterfeits of brand-name products have also come out, and countermeasures have become important. For example, the method of attaching IC tags to articles is one of the leading methods. is there.

  There are many counterfeit products in the field of pharmaceuticals and cosmetics, and health damage due to drugs of counterfeit products has been reported, and pharmaceutical manufacturers have hidden letters and designs such as fluorescent printing on packaging containers as measures to prevent counterfeit products. (See Patent Document 1) so that the authenticity of the product can be determined.

JP 09-255861 A

  In the above-described conventional technology, imitation prevention information is printed in advance on the surface of the container with transparent fluorescent ink, and the imitation prevention information that is difficult to visually recognize under visible light is irradiated by ultraviolet (black light) irradiation. It is made visible by making it emit fluorescent light so that the authenticity of the product can be determined by the presence or absence of the counterfeit prevention information.

  However, in the conventional anti-counterfeiting technology described above, anti-counterfeit information printed with fluorescent ink is provided on the surface of the product. If the existence is easily known and the existence of anti-counterfeiting information is known, information similar to the anti-counterfeiting information is printed using the same fluorescent ink, and a counterfeit product is created. It was.

  Therefore, the present invention was devised to solve the above-described problems in the prior art, and it is a technical problem to make it difficult to visually recognize the presence of imitation prevention information printed with fluorescent ink under visible light. Therefore, the purpose is to obtain a highly reliable counterfeit prevention effect.

The main configuration of the present invention for solving the above technical problem is:
A multi-wall structure in which a display body in which a decorative display body and a fluorescent display body are integrally provided is positioned between an outer wall and an inner wall which are injection molded products made of synthetic resin;
Making the outer and inner walls transparent and UV transmissive,
The decorative display body has a decorative display layer that displays a product name, a decorative pattern, etc. on the outside of one base sheet,
The fluorescent display is formed on the inner side of the base sheet, and has a fluorescent display layer that displays imitation prevention information such as hidden characters and designs by printing fluorescent ink that emits fluorescence when irradiated with ultraviolet rays .
Make the base sheet UV-absorbing,
Configuring this fluorescent display layer to be difficult to view with visible light,
It is in.

  Since the fluorescent display is located between the outer wall and the inner wall, which is an injection molded product made of synthetic resin, in a state where the fluorescent display is positioned on one surface of the molded outer wall and inner wall, On the other hand, the other side needs to be positioned on the surface side where the fluorescent display body is positioned. For this reason, a certain procedure is required for handling the fluorescent display body when manufacturing the fluorescent display body.

  Since the fluorescent display is located between the outer wall and the inner wall, the fluorescent display layer that displays the imitation prevention information formed on the fluorescent display is visible through the outer wall or the inner wall. However, since the fluorescent display layer formed of fluorescent ink is difficult to visually recognize with visible light, its presence is difficult to visually recognize. In particular, visible light from the fluorescent display layer is subjected to optical influences (distortion, etc.) from the outer wall or inner wall when passing through the outer wall or inner wall. Tend to be.

  In addition, if the other of the outer wall and the inner wall is opaque, it is impossible to visually recognize the fluorescent display from the other side regardless of whether the fluorescent display is irradiated with ultraviolet rays. In order to recognize, it is necessary to observe by irradiating ultraviolet rays from one side, and it is troublesome and difficult to recognize the presence of the fluorescent display.

  Another configuration of the present invention is configured such that in the main configuration described above, the fluorescent ink is transparent and the fluorescent display layer is hardly visible with visible light.

  In the case where the fluorescent ink is transparent, the fluorescent ink itself is difficult to visually recognize with visible light, and thus the fluorescent display layer formed with this transparent fluorescent ink is difficult to visually recognize with visible light. .

  Another configuration of the present invention is that in the main configuration described above, the fluorescent ink is made the same color as the portion where the fluorescent display layer is formed, so that the fluorescent display layer is hardly visible with visible light.

  If the fluorescent ink is the same color as the part where the fluorescent display layer is formed, the fluorescent display layer is observed in the background color under visible light. It is extremely difficult to see with visible light.

Another configuration of the present invention, in addition to the main structure described above, the inner wall which is fixed the fluorescent display member on the outer surface as the insert material and insert molded and the other is intended.

As the inner side wall of the insert member which is fixed the fluorescent display member, in the the other to those insert molding with integral assembly of the outer wall and the inner wall is firmly and closely achieved, fluorescent display Since the body and the other insert-molded part can be sufficiently closely assembled, the presence of the fluorescent display body due to the insufficient attachment of the fluorescent display body and the other insert-molded part is visually confirmed. Occurrence of inconvenience that it becomes easy can be eliminated.

Another configuration of the present invention, in addition to the main structure described above, the fixation of the fluorescent display member to the inner side wall, was achieved by in-mold molding is intended.

The fixation of the fluorescent display member to the inner side wall, the apparatus having that achieved by in-mold molding, the fixing of the inner sidewall and the fluorescent display member, can be sufficiently tightly and firmly achieved, among this It is possible to eliminate the inconvenience that it is easy to visually recognize the presence of the fluorescent display due to insufficient fixation between the side wall and the fluorescent display.

In the main configuration of the present invention, in a case where a decorative display body having a decorative display layer for displaying a product name, a decorative pattern, etc. is provided integrally with a fluorescent display body, a single display body is used for decoration. Display and fluorescent display can be performed.

In the main configuration of the present invention , a decorative display body is formed on the outer side of one base sheet and a fluorescent display body is formed on the inner side, and the base sheet is made to absorb ultraviolet rays . It is impossible to visually recognize the fluorescent display from the outside, and accordingly, it is difficult for a mimic to recognize the presence of the fluorescent display.

Since the present invention has the above-described configuration, the following effects can be obtained.
In the main configuration of the present invention, a certain procedure is required for the handling of the fluorescent display when it is manufactured. For this reason, even if the presence of the fluorescent display is detected, the fluorescent display is fixed. It is difficult to imitate.

  In addition, since the fluorescent display layer of the fluorescent display located between the outer wall and the inner wall is configured to be difficult to visually recognize with visible light, the presence of the fluorescent display can be recognized from the outside with visible light. Therefore, high concealability of the fluorescent display can be obtained, and an imitation preventing effect by the fluorescent display can be obtained.

  Furthermore, if the other of the outer wall and the inner wall is opaque, a certain procedure is required for recognizing the presence of the fluorescent display, so that the presence of the fluorescent display can hardly be recognized from the outside. Therefore, high concealability of the fluorescent display can be obtained, and an imitation preventing effect by the fluorescent display can be obtained.

  If the fluorescent ink is transparent and the fluorescent ink is the same color as the part where the fluorescent display layer is formed, make sure that the fluorescent display layer formed of the fluorescent ink is visible with visible light. This makes it difficult to imitate the fluorescent display itself.

  In the case where one of the outer wall and the inner wall to which the fluorescent display body is fixed is used as an insert material, and the other is insert-molded, the close contact assembly between the fluorescent display body and the other insert-molded is insufficient. Since the occurrence of inconvenience that it becomes easy to visually recognize the presence of the fluorescent display can be eliminated, the high concealability of the fluorescent display can be reliably obtained.

  In the case where the fluorescent display is fixed to the outer wall or the inner wall by in-mold molding, the fluorescent display is present due to insufficient fixation between the outer or inner wall and the fluorescent display. Since it is possible to eliminate the inconvenience that it is easy to visually recognize the fluorescent display, the high concealability of the fluorescent display can be obtained with certainty.

  In the case where a decorative display body is provided on the outer surface of the outer side wall and the outer wall is opaque, it is impossible to visually recognize the fluorescent display body from the outside of the multiple wall structure. However, it is difficult to recognize the presence of the fluorescent display, and thereby, the imitation prevention effect by the fluorescent display can be obtained with a high probability.

  In the case where a decorative display body having a decorative display layer for displaying a product name, a decorative pattern, etc. is provided integrally with the fluorescent display body, the decorative display and the fluorescent display should be performed with a single display body. Therefore, it is possible to simply display the multi-wall structure.

  If the decorative display body is formed on the outside of one base sheet and the fluorescent display body is formed on the inside, and the base sheet is opaque, the fluorescent display body should be visually recognized from the outside of the multi-wall structure. Therefore, it is difficult for the mimic to recognize the presence of the fluorescent display, and thus the anti-imitation effect by the fluorescent display can be obtained with a high probability.

It is a half longitudinal section showing the example of the 1st reference form of the present invention. It is a principal part expanded longitudinal cross-sectional view of the example of a reference form shown in FIG. It is a semi-longitudinal sectional view showing a second embodiment of the present invention. FIG. 4 is an enlarged longitudinal sectional view of a main part of the embodiment shown in FIG. 3.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a semi-longitudinal sectional view showing a first reference embodiment in which the present invention is implemented in a box-shaped wide-mouth cream container. The cream container has an upper end opening and a thread on the outer peripheral surface. The inner wall 2 made of synthetic resin injection-molded into a bottomed cylinder shape as a screw cylinder and the bottom-walled cylinder shape that tightly covers and covers the outer surface excluding the upper end opening of the inner wall 2 The outer wall 1 is made of synthetic resin.

  FIG. 3 is a semi-longitudinal sectional view showing a second embodiment in which the present invention is applied to a large screw cap. The screw cap is an outer wall 1 made of a synthetic resin which is injection-molded into a top tube shape. Then, the outer wall 1 is covered with the entire outer surface and is tightly assembled, and the inside of the cylindrical wall portion is injection-molded into a crested cylindrical shape in which a screw tube with a thread is engraved on the inner surface. And an inner wall 2 made of synthetic resin.

  A fluorescent display 5 is arranged between the outer side wall 1 and the inner side wall 2 (between the cylindrical wall portions in both embodiments). The fluorescent display body 5, the outer wall 1 and the inner side wall 2 are connected to each other. The assembly is strong and dense, so that a slight gap is not generated particularly due to insufficient adhesion. This is because, when a slight gap is generated between the fluorescent display 5 and the outer wall 1 or the inner wall 2, the visible light from the fluorescent display 5 is distorted by the influence of the gap, and this distortion causes the fluorescent display. This is because the existence of 5 will be known.

  Assembling the fluorescent display 5 to the outer wall 1 or the inner wall 2 is made strong and dense by in-molding the outer wall 1 or the inner wall 2 using the fluorescent display 5 as an in-mold material. It becomes possible to do.

  The fluorescent display 5 (refer to FIG. 2 and FIG. 4 hereinafter) prints imitation prevention information on one side of the base sheet 8 with transparent fluorescent ink or fluorescent ink of the same color as the base sheet 8, and this is displayed on the fluorescent display 7a. As a fluorescent display layer 7, a protective layer 9 that covers and protects the fluorescent display layer 7, and a base sheet 8, an adhesive layer 10 that covers both sides of the laminate of the fluorescent display layer 7 and the protective layer 9. ing.

  The fluorescent display layer 7 of the fluorescent display 5 emits fluorescent light when irradiated with ultraviolet rays (black light) to display the fluorescent display 7a which is imitation prevention information. At least one is transparent and ultraviolet transmissive, and the fluorescent display 7a appears by irradiating ultraviolet rays from the transparent and ultraviolet transmissive side.

  In addition, since the fluorescent display 5 is disposed between the outer wall 1 and the inner wall 2, the fluorescent display layer 7 of the fluorescent display 5 is always visible through the outer wall 1 or the inner wall 2. Therefore, the transmitted light of visible light from the fluorescent display layer 7 is affected by the outer wall 1 or the inner wall 2, and it is extremely difficult to recognize the presence of the fluorescent display layer 7 with visible light. Therefore, the effect of preventing imitation by the fluorescent display 5 is effectively exhibited.

In the first reference embodiment shown in FIG. 1, separately from the fluorescent display 5, a decorative display 4 is fixed to the outer surface of the outer wall 1, and this decorative display 4 is A decorative display layer 6 that displays a product name, a decorative pattern, and the like is formed by printing, and the outer wall 1 is in-molded using the decorative display body 4 as an in-mold material. The assembly of the decorative display body 4 is made strong and dense.

The decorative display body 4 (see FIG. 2) of the first reference embodiment is a display that displays the decorative display 6a on the outer surface of the base sheet 8 in which the adhesive layer 10 is laminated on the inner surface. The decorative display layer 6 is formed by printing, and the decorative display layer 6 is covered and a protective layer 9 is laminated. The display body 3 is configured by a combination of the decorative display body 4 and the fluorescent display body 5. ing.

Further, in the second embodiment shown in FIG. 3 constitutes a display member 3 so as to be integrated decorative display member 4 and the fluorescent display member 5, the inner surface of the base sheet 8, fluorescent The display layer 7, the protective layer 9, and the adhesive layer 10 are laminated in order to form the fluorescent display 5. Conversely, the decorative display layer 6, the protective layer 9, and the adhesive layer 10 are formed on the outer surface of the same base sheet 8. The display body 3 is configured by sequentially laminating and forming a decorative display body 4.

  In this second embodiment, the decorative display body 4 is integrated with the fluorescent display body 5 and is positioned between the outer wall 1 and the inner wall 2 so that the decorative display 6a appears. In order to make it possible, the outer wall 1 must be transparent.

In the first reference embodiment, when the outer wall 1 is transparent and UV transmissive, and the base sheet 8 of the fluorescent display 5 added thereto is transparent and UV transmissive, the fluorescence of the fluorescent display 5 The fluorescent display 7a on which the display layer 7 appears can appear on the outer surface of the outer wall 1 (see FIG. 3), like the decorative display 6a, but the outer wall 1 is opaque or UV-absorbing, or When the base sheet 8 of the fluorescent display 5 is opaque or absorbs ultraviolet rays, the fluorescent display 7a cannot appear on the outer surface of the outer wall 1, and the inner surface of the inner wall 2 (FIG. 1). It can appear only on the reference) side.

Similarly, in the second embodiment, when the outer wall 1 is transparent and UV transparent, and the base sheet 8 of the fluorescent display 5 added thereto is transparent and UV transparent, the fluorescent display The fluorescent display 7a appearing on the fluorescent display layer 7 of 5 can appear on the outer surface of the outer wall 1 (see FIG. 3), like the decorative display 6a, but the base sheet 8 of the display 3 is when a ultraviolet absorbent, the fluorescent display 7a becomes impossible is to appear on the outer surface of the outer wall 1, thereby enabling emerge only on the inner surface (see FIG. 1) side of the inner wall 2 .

  When the fluorescent display 7a can appear only on the inner surface side of the inner wall 2, the product imitator can inspect ultraviolet rays from the outside in order to check whether the purchased product has the fluorescent display 5 or not. Since the presence of the fluorescent display body 5 cannot be detected even if it is irradiated, there is almost no possibility that the fluorescent display body 5 is imitated by an imitator, thereby exhibiting a very high anti-imitation effect.

  In particular, the base sheet 8 of the fluorescent display 5 configured as shown in FIG. 2, or the base sheet of the display 3 configured integrally with the decorative display 4 and the fluorescent display 5 shown in FIG. 4. When 8 is made opaque, visible light from the fluorescent display layer 7 formed on the fluorescent display 5 is not irradiated on the outer wall 1 side, so that the presence of the fluorescent display 5 is detected by a mimic. The fear of being lost will be completely eliminated.

  Although the illustrated embodiment is a double wall structure of the outer wall 1 and the inner wall 2, the present invention is not limited to the double wall structure, and has a double or more multiple structure. There may be a combination with a wall having a laminated structure.

  As described above, the multi-wall structure of the present invention has a discrimination function related to counterfeit products by a fluorescent display that is difficult to detect the presence or imitates manufacture, and has a wide range of usage development as a countermeasure against counterfeit products. Be expected.
