JP 2004-115112 A

  In the blister pack as shown in FIG. 4, since the place where the product name and the feature of the product can be printed is limited to both sides of the mount, it is common to perform double-sided printing on the mount. When performing double-sided printing on the mount, the mount needs to be light-shielded so that the printed content on one side cannot be seen through from the other side.

  However, in the case of using a light-blocking mount, there is a problem that it is difficult to see a part of the object to be accommodated facing the front side of the mount.

  Therefore, an object of the present invention is to provide a blister pack capable of expanding a visible range of an object to be contained.

  The blister pack according to the present invention is made of a molded product of a resin sheet, and includes a container main body having a storage portion for storing an object to be stored and a flange portion connected to the periphery of the storage portion, and a storage portion and a flange portion of the container main body. A sheet material attached to the container body so as to cover the sheet material, and the sheet material is provided with a light transmissive region having light transmissive property and a light shielding region having light shielding property.

More specifically, FIG. 1 (a) is a front view of a blister pack, FIG. 1 (b) is a back view of the blister pack, and FIG. 1 (c) is a side view of the blister pack. It is the figure seen from the AA 'line of FIG.1 (b).

  The blister pack 1 includes a container main body 2 and a sheet material 3, and a toothbrush 4 that is an object to be stored is accommodated in a space formed by the container main body 2 and the sheet material 3. As shown in FIG. 1, the toothbrush 4 is accommodated with the portion provided with the bristles facing the sheet material 3 side.

  The container body 2 includes a housing part 5 that houses the toothbrush 4 and a flange part 6 that is connected to the periphery of the housing part 5. The accommodating part 5 is formed as a recessed part recessed from the plane including the flange part 6, and has a shape capable of accommodating the toothbrush 4 which is an object to be accommodated. As an example, the container main body 2 can be manufactured by vacuum forming of a transparent resin sheet (resin film) such as polyethylene terephthalate (PET).

  The sheet material 3 has a shape substantially corresponding to the planar shape of the container main body 2, and is sealed by the flange portion 6 of the container main body 2 in a state of covering the housing portion 5 and the flange portion 6 of the container main body 2. In the configuration in which the sheet material 3 and the flange portion 6 are sealed as in the present embodiment, it suffices that at least a part of the flange portion 6 around the peripheral portion of the housing portion 5 is sealed by the sheet material 3. You may provide an unsealable part partially in the part etc. which become a hook at the time of opening of the pack 1. FIG.

  The sheet material 3 is provided with a light transmissive region having a light transmissive property and a light shielding region having a light shielding property (hiding property of the object to be stored). In the present embodiment, a window region 8 is provided as a light transmission region, and regions other than the window region 8 are shielded from light. Therefore, in the blister pack 1 according to the present embodiment, a part of the toothbrush 4 accommodated in the blister pack 1 can be visually recognized through the window region 8.

  Further, as shown in FIGS. 1A and 1B, printing is performed on areas other than the window area 8 provided on the sheet material 3, that is, on both sides of the light shielding area. However, in the blister pack 1 according to the present embodiment, the front surface (front side) of the blister pack 1 is opposite to the surface of the sheet material 3 opposite to the surface sealed by the flange portion 6 of the container body 2. Prints to indicate that there is. Moreover, in this embodiment, the printing which displays information, such as a barcode and a material, is given to the surface sealed by the flange part 6 of the sheet | seat material 3. FIG. That is, the printed content of the sheet material 3 of the blister pack 1 according to the present embodiment is opposite to the printed content of the mount of the conventional blister pack shown in FIG.

  Furthermore, a hook 7 is formed on a part of the peripheral portion of the blister pack 1 by partially cutting out an overlapping portion between the flange portion 6 of the container body 2 and the sheet material 3. The hook 7 is used to suspend the blister pack 1 on a bar or the like provided on the display shelf when displaying the product. The blister pack 1 according to the present embodiment is displayed so that the sheet material 3 faces the front.

  Here, the details of the layer configuration of the sheet material 3 will be described.

  FIG. 2 is a cross-sectional view showing the layer structure of the sheet material constituting the blister pack shown in FIG.

  The sheet material 3 includes a first resin film 11, a metal vapor deposition layer 15 laminated on one surface (the lower surface in FIG. 2) of the first resin film, and the other surface (an upper surface in FIG. 2). ) Of the first printing ink layer 21 laminated on the light shielding region, the second resin film 12 laminated on the first printing ink layer, and the second printing ink laminated on the metal vapor deposition layer 15. The layer 22 includes a third resin film 13 laminated on the second printing ink layer 22, and a sealant layer 16 laminated on the third resin film 13.

  The first resin film 11, the second resin film 12, and the third resin film 13 are transparent resin films. The 2nd resin film 12 and the 3rd resin film 13 are for protecting the 1st printing ink layer 21 and the 2nd printing ink layer 22, respectively. Further, by laminating the first resin film 11, the second resin film 12 and the third resin film 13, the sheet material 3 has a stiffness (rigidity) suitable for a packaging machine similar to paper. Can be granted. For the first resin film 11, the second resin film 12, and the third resin film 13, for example, a PET film can be used.

  The metal vapor deposition layer 15 is a layer that imparts light shielding properties to the sheet material 3, and is, for example, an aluminum vapor deposition layer. The metal vapor deposition layer 15 is laminated on a region of the one surface of the first resin film 11 excluding the region that becomes the window region 8. Thereby, the area | region which provided the metal vapor deposition layer 15 among the 1st resin films 11 turns into a light-shielding area which has light-shielding property, and the area | region which does not provide the metal vapor deposition layer 15 is transparent 1st resin film 11, 2nd It becomes a light transmission region capable of transmitting light through the resin film 12, the third resin film 13 and the sealant layer 16.

  The first printing ink layer 21 is formed by printing the printing ink on a light shielding region on the surface opposite to the surface on which the metal vapor deposition layer 15 is provided in the first resin film 11, and the front surface of the blister pack 1. It is a layer that displays the contents. On the other hand, the second printing ink layer 22 is a layer formed by printing printing ink on the metal vapor deposition layer 15 provided on the first resin film 11.

  Further, in the example of FIG. 2, the region 9 where the first printing ink layer 21 is not partially provided is formed on the light shielding region. By forming the first printing ink layer 21 in this way, as shown in FIG. 1A, the metal vapor deposition layer 15 is formed in the region 9 through the first resin film 11 and the second resin film 12. appear. Therefore, a design with metallic luster can be formed on the front side of the sheet material 3 by making the region 9 a desired shape such as a character or a predetermined figure. Similarly to the region 9, by providing a region where the second printing ink layer 22 is not partially provided on the light-shielding region, the back side of the sheet material 3 can be provided with a design such as characters and figures having metallic luster. good. Further, instead of providing an area without an ink layer on the light-shielding area, an area in which the thickness of the printing layer is made thinner than other parts or an area printed with a printing ink having a lighter color than other parts may be provided. . If comprised in this way, the design which the metal luster of the metal vapor deposition layer 15 can be seen through printing ink can be formed in a part of surface or back surface of the sheet | seat material 3. FIG.

  The sealant layer 16 is a layer used for sealing the sheet material 3 to the flange portion 6 of the container body 2. For example, an easy peel film or a hot melt film can be used for the sealant layer 16.

  FIG. 3 is a cross-sectional view illustrating an example of a method for manufacturing the sheet material illustrated in FIG. 2.

  First, as shown in FIG. 3A, the metal vapor deposition layer 15 is formed on one surface (the lower surface in FIG. 3) of the first resin film 11.

  Next, as shown in FIG. 3B, printing is performed on both surfaces of the first resin film 11, and the first printing ink layer 21 and the first printing region other than the region that becomes the light transmission region (window region 8). Two printing ink layers 22 are formed. At this time, when a design having metallic luster is applied to the surface of the sheet material 3, a region 9 having no printing ink is partially formed on the light shielding region. Although not shown, when a design having metallic luster is applied to the back surface of the sheet material 3, a region without printing ink may be provided in the light shielding region on the second printing ink layer 22 side. The order of forming the first printing ink layer 21 and the second printing ink layer 22 may be arbitrary.

  Next, as shown in FIG. 3C, the second resin film 12 is laminated on the first printing ink layer 21. Although the lamination | stacking method of the 1st resin film 11 and the 2nd resin film 12 which provided the 1st printing ink layer 21 is not specifically limited, For example, the dry lamination method can be utilized suitably.

  Next, as shown in FIG. 3D, a part of the metal vapor deposition layer 15 exposed from the second printing ink layer 22 is removed. The removal of the metal deposition layer 15 is preferably performed by, for example, a paster process in which the exposed metal deposition layer 15 is dissolved and removed using an alkaline solution such as an aqueous sodium hydroxide solution or a strong acid solution such as sulfuric acid, and then neutralized and washed with water. Available. By removing the metal vapor-deposited layer 15, a light transmissive region (window region 8) having light transmittance is formed.

  In order to prevent the second printing ink layer 22 from being eroded by the alkaline solution or the acid solution during the paster processing, the second printing ink layer 22 is made resistant to alkali resistance or acid according to the liquid property of the solution used in the paster processing. It is preferable to form with the printing ink which has tolerance. By forming the second printing ink layer 22 with printing ink having alkali resistance or acid resistance, there is no need to provide a protective layer such as a protective varnish for protecting the second printing ink layer 22 during paster processing. Therefore, the manufacturing process can be simplified and the cost can be reduced. The alkali resistance or acid resistance of the second printing ink layer 22 may be such that it can withstand erosion by the treatment liquid at least during the immersion time in the alkali solution or acid solution during the paster processing. On the other hand, since the 1st printing ink layer 21 is protected by the 2nd resin film 12, the ink used for the 1st printing ink layer 21 is not specifically limited. Moreover, since the 1st printing ink layer 21 is protected by the 2nd resin film 12 so that it may not erode during a paster process, printing of the 1st printing ink layer 21 used as a front surface is carried out by an alkaline solution or an acid solution. It is also possible to use an ink containing an aluminum paste such as silver ink or gold ink which is easily corroded.

  Next, as shown in FIG. 3E, the third resin film 13 is laminated on the second printing ink layer 22. Although the lamination | stacking method of the 1st resin film 11 and the 3rd resin film 13 which provided the 2nd printing ink layer 22 is not specifically limited, For example, the dry lamination method can be utilized suitably.

  Next, as shown in FIG. 3 (f), by forming a sealant layer on the third resin film 13, the sheet material 3 having a light transmission region and a light shielding region can be obtained. Although the lamination | stacking method of the 3rd resin film 13 and the sealant layer 16 is not specifically limited, For example, the dry lamination method can be utilized suitably.

  Apart from the obtained sheet material 3, the container body 2 is manufactured by vacuum forming of a resin sheet or the like. After the toothbrush 4 is accommodated in the accommodating portion 5 of the container main body 2, the obtained sheet material 3 is sealed to the flange portion 6 of the container main body 2, whereby the packaged body in which the items to be accommodated are accommodated in the blister pack 1 (FIG. 1). ) Is obtained.

  As described above, in the blister pack 1 according to the present embodiment, since the window region 8 that is a light transmission region is provided in the sheet material 3, not only from the container body 2 side but also from the front side of the sheet material 3. In addition, a part of the toothbrush 4 that is an object to be accommodated can be visually recognized through the window region 8. Therefore, according to the present embodiment, it is possible to realize the blister pack 1 in which the range in which the object is visible is wide as compared with the conventional configuration shown in FIG.

  In addition, since the portion of the sheet material 3 other than the window region 8 is shielded from light by the metal deposition layer 15, even if printing is performed on both sides of the light shielding region, the printed content on one side is transparent from the other side. I can't see it. In addition, when the light is shielded by the metal vapor deposition layer 15, high light-shielding properties can be obtained, so that a color having a high brightness such as white is favorably developed. Accordingly, it is possible to realize a design having a refreshing feeling mainly composed of white, and the degree of freedom of the design is improved.

  Although it is technically possible to form a light-shielding region by providing a printing layer for the purpose of light shielding instead of the metal vapor-deposited layer 15, depending on the contents to be packaged in a blister pack, it is suitable for the following reasons. There may not be. In order to achieve the same degree of light-shielding properties as the metal vapor-deposited layer 15, it is necessary to use a printing ink with a low lightness such as black or gray and increase the amount of printing ink applied to form a thick light-shielding printing layer. is there. However, when printing ink with low brightness is used as the light shielding layer, the color of the printing applied on the light shielding layer becomes dull and dark, and the printed design may not match the image of the product. In addition, when the amount of printing ink applied is increased, the solvent in the printing ink tends to remain in the sheet material, or the diluted solvent of the adhesive used for dry lamination of the resin film tends to remain in the printing ink layer. . When the sheet material in which the solvent in the printing ink or the diluted solvent of the adhesive remains is used, the solvent remaining after the blister pack is produced volatilizes and fills the blister pack, which causes odor when opened. Odor generation due to the solvent is not preferable for blister packs used for packaging toiletries such as toothbrushes. Therefore, the metal vapor deposition layer 15 can be used as a light shielding layer as in the present embodiment in that the problem of odor caused by the residual solvent can be solved and the color developability of the printing ink can be improved to obtain an excellent design. Is preferably adopted.

  Furthermore, in the blister pack 1 according to the present embodiment, it is displayed on the surface opposite to the side facing the flange portion 6 of the container body 2 among both surfaces of the sheet material 3 that it is the front of the product at the time of display. Printing (first printing ink layer 21) is performed. In the conventional blister pack shown in FIG. 4, since the surface of the mount on the container body side is the front of the product when displayed, printing indicating the front of the product through the container body is displayed. In this case, the visible area on the mount is limited by the objects contained in the container main body, and the printed content on the mount is viewed through the container main body, which makes it difficult to see the printed content. . On the other hand, in the blister pack 1 according to the present embodiment, the surface opposite to the container main body 2 in the sheet material 3 is the front surface, so that the printing area on the front surface of the sheet material 3 is not narrowed by the object to be contained. Moreover, since the front surface of the sheet material 3 is substantially flat, it is possible to realize the blister pack 1 in which the printed content is easy to see.

  Furthermore, in the blister pack 1 according to the present embodiment, the light transmission region is formed as a window region 8 surrounded by the light shielding region. In this way, by setting the light transmission region as the window region 8, it is possible to focus attention on the portion visible through the window region 8 when the blister pack 1 is displayed.

(Other variations)
In the above embodiment, the example in which the container body 2 is formed using a transparent resin sheet (resin film) has been described. However, the container body 2 may be formed using an opaque resin sheet (resin film). good. Even in this case, by providing the light transmission region in the sheet material 3, it is possible to widen the visible range of the object to be stored as compared to the case of using the sheet material that is shielded from the whole.

  In the above embodiment, the metal vapor deposition layer 15 is provided on the surface of the first resin film 11 on the sealant layer 16 side. However, the metal vapor deposition layer 15 may be provided on the side opposite to the sealant layer 16. In other words, the sealant layer 16 may be laminated on the second resin film 12 instead of on the third resin film after the step shown in FIG.

  Furthermore, in said embodiment, although the blister pack 1 which sealed the sheet | seat material 3 to the flange part 6 of the container main body 2 was illustrated, the sheet | seat material 3 may be attached to the container main body by methods other than a seal | sticker. For example, you may employ | adopt the structure of the sheet | seat material 3 which concerns on this invention to the slide-type blister pack which bent the peripheral part of the flange part 6 and inserted the sheet | seat material 3 slidably. Moreover, you may employ | adopt the structure of the sheet | seat material 3 which concerns on this invention to the blister pack of the structure which attached the sheet | seat material 3 to the container main body 2 with the stapler.

  Further, in the above-described embodiment, an example in which one elliptical window region 8 is provided in the sheet material 3 as the light transmission region has been described, but the number and shape of the window regions 8 are not particularly limited. Further, the light transmission region may not have a shape surrounded by the light-shielding region as in the above-described embodiment, and a part of the peripheral part of the sheet material 3 and a peripheral part different from the part may be provided. It may be a region including another part.

  Furthermore, in the above-described embodiment, an example in which printing is performed on the surface opposite to the container body 2 side of the sheet material 3 to indicate that it is the front of the blister pack 1 has been described. You may perform double-sided printing so that the surface of 2 side may become the front at the time of display. Even in this case, it is possible to obtain the same effect as in the present embodiment that the visible range of the objects to be accommodated in the blister pack 1 is widened. Even in this case, by forming the light-shielding region with the metal vapor-deposited layer 15, it is possible to obtain excellent light-shielding property (concealment of the object to be contained) and good color development of the printing ink.

  Furthermore, in said embodiment, the resin sheet and resin film for forming the sheet | seat material 3 and the container main body 2 do not necessarily need to be colorless and transparent, and if it has a light transmittance, it will be colored, or it may be translucent. There may be.

  Furthermore, in said embodiment, the example which utilizes the metallic luster of the metal vapor deposition layer 15 for a design by providing the area | region 9 without a printing ink in the 1st printing ink layer 21 or the 2nd printing ink layer 22 was demonstrated. However, whether or not to provide the region 9 is arbitrary.

  Furthermore, in said embodiment, although the case where the to-be-contained object of the blister pack 1 was a toothbrush was illustrated, the content is not specifically limited, Even if it contains the to-be-contained object other than a toothbrush similarly, said embodiment Needless to say, the same effect can be obtained.

  Further, in the above embodiment, the hook 7 for suspending the blister pack 1 at the time of display is provided. For example, the hook 7 may not be provided.

  INDUSTRIAL APPLICATION This invention can be utilized for the blister pack for packaging toiletry goods, such as a toothbrush, a dry cell, a stationery, etc.
