Description

  The present invention relates to a synthetic resin container having a surface that is decorated to give a three-dimensional visual effect.

  In the case of a container for cosmetics or the like where the decoration of the container occupies a large portion of the product power, it is desired to enhance the product image by exhibiting the decorativeness by painting, printing, etc., and greatly improving the product image. For example, in Patent Document 1, a large and small pattern is formed by printing a pattern with large and small dots with colored ink on the surface of a storage container body at a portion covered by a lid, and molding or printing with a transparent ink on the outer surface of the lid. There is a description of a cosmetic container characterized by having an overall pattern to which a moire pattern effect is added by forming a pattern with convex dots.

Patent Document 2 discloses a decorative property that creates a three-dimensional pattern on a sheet by optical interference between both sides of the sheet by forming a pattern portion having a pattern repeated at a predetermined pitch on both sides of the transparent sheet. There is a description about the sheet.

JP 2004-181037 A Japanese Patent Laid-Open No. 11-189000

  If the moiré pattern or the three-dimensional pattern (which is also a category of the moiré pattern) in Patent Document 1 described above can be freely expressed on the outer surface without depending on the shape of the container, the decoration effect is very high. However, in a molded article such as a container, it is difficult to form a pattern on the inner surface opposite to a predetermined portion of the outer surface of the container by a normal processing method. The part which can be decorated, such as forming a pattern on the surface, is limited, and the decoration effect is also limited. Moreover, since it is necessary to form a pattern in a plurality of molded products such as the storage container main body and the lid, the cost increases.

  In addition, a method of applying a decorative sheet having a three-dimensional effect described in Patent Document 2 to a container like a label is conceivable, but there are restrictions on the application location depending on the shape of the outer surface, and the label can be printed or the like Since it is inferior in unity with the container body in comparison, there is a sense of one step further as decorativeness. Furthermore, in the case of a label, since a label manufacturing process and a label sticking process are required, the cost increases.

  Therefore, the present invention has a technical problem to form a moire pattern-like pattern on a container body that is a single molded product while having a sense of unity with the container body at a low cost and at a low cost. An object of the present invention is to provide a synthetic resin container provided with a unique decorative effect.

Among the methods for solving the technical problem, the means of the invention according to claim 1 is:
In a synthetic resin container,
Making the container body transparent,
A first printed layer on which a pattern having a first regularity is printed on a predetermined portion on the outer surface of the container body, and a second printed on the outer surface facing the portion on which the first printed layer is printed on the container body. Having a second printed layer printed with a pattern having regularity of:
The decoration by the three-dimensional visual effect is given by the light interference effect by the both patterns of the first printed layer and the second printed layer through the transparent container body,
It is in.

According to the above-described configuration, the first printed layer and the second printed layer, each of which is printed with a pattern having a predetermined regularity, are opposed to each other with a transparent container interposed therebetween on the outer surface of the container wall. A three-dimensional visual effect is exerted by the interference of light through the moiré pattern, and a moire pattern appears on the wall surface of the container. Further, by storing the transparent content liquid in the container main body, a decorative effect that has never been achieved is exhibited in combination with the prismatic effect of the content liquid.
Even when the opaque content liquid is stored, the moire pattern appears intermittently every time the consumer consumes the content liquid, and the taste is added.

  In addition, in the said structure of Claim 1, a colorless transparent and colored transparent container main body can be used, and the cross-sectional shape of a container main body should just be a shape which has opposing surfaces, such as a rectangle and a circle | round | yen The overall shape of the container main body is preferably a parallelepiped shape such as a rectangular parallelepiped shape or a drum shape, but may be a cylindrical shape or a cone shape.

  The pattern having a predetermined regularity has various forms such as a pattern in which parallel lines are arranged at a predetermined pitch, a square lattice pattern, a pattern in which dots are arranged in a punched-metal pattern, a concentric circle, and the like. The moire pattern generated by a combination of these is one of regular patterns.

  Moreover, it is common to print a pattern, a design, a character, etc. in the container used for cosmetics etc. According to the said structure of Claim 1, printing of a 1st printing layer and a 2nd printing layer is carried out. Ordinarily used printing methods such as a screen printing method and an offset printing method are possible.

  In addition, as described above, the first printing layer and the second printing layer can be easily formed by a normal printing method, and therefore, for example, a curved portion other than a very complicated portion can be easily formed with the container body. It can be formed while ensuring a sense of unity, and the decorativeness by the three-dimensional visual effect can be easily applied at a low cost without adding a special process as a whole.

  The ink and paint used for the printing of the first printing layer and the second printing layer and the clear coat layer described later are ordinary ultraviolet or electron beam curable types, evaporative drying types, two-component curable types, oxidation polymerization types, and the like. Ink and paint can be used, but it is preferable from the viewpoint of productivity to use an ultraviolet ray or electron beam curable type. When using UV or electron beam curable ink or paint, print or paint with UV or electron beam curable ink or paint, and then irradiate the printed or painted surface with UV or electron beam to remove the ink or paint. It can be cured quickly.

  According to a second aspect of the present invention, in the first aspect of the invention, in addition to a regular pattern, a pattern, a design, or a character is printed on at least one of the first print layer and the second print layer. That's it.

  According to the above-described configuration, the moiré pattern can be represented on the back so that a pattern, a design, a character, or the like emerges or sinks, and a more unique decoration or display effect can be exhibited.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, a third print in which a pattern, a design, a character, or the like is printed on the first print layer or the second print layer via a clear coat layer. Having layers stacked.

  In the third aspect of the present invention, a pattern, a design, a character, or the like is formed on a third printed layer different from the first printed layer or the second printed layer. More specifically, for example, the second printed layer is covered with a clear coat layer, and a third printed layer is formed on the clear coat layer by printing a pattern, design, character, or the like. For example, three print layers are formed, the third print layer is covered with a clear coat layer, and the first print layer is printed on the clear coat layer.

  According to the above-described configuration, the first printing layer, the second printing layer, and the third printing layer can be printed by a commonly used printing method such as a screen printing method or an offset printing method. In addition, the clear coat layer is a colored or non-colored transparent layer, but uses a transparent ink similar to the printing ink used for printing the first printing layer, the second printing layer, and the third printing layer. In order to form the film as thick as possible, it is preferable to form it by a screen printing method. The clear coat layer can also be formed by a normal coating process such as spray coating, dip coating, or roll coating.

  In the third aspect, the moiré pattern can be expressed so that a pattern, a design, a character, or the like appears or sinks on the back as in the configuration described in the second aspect. Since the characters and the like are laminated as the third printed layer through the clear coat layer, a decorative effect different from the effect of the configuration according to claim 2 is exhibited. Furthermore, by drawing a pattern, a design, a character, or the like in a transparent color, an effect that a moire pattern and a design, a design, or a character are fused can be obtained.

The means of the invention described in claim 4 is:
In a plastic container,
Having a transparent container body,
Having a concavo-convex forming part in which a pattern having a first regularity is formed on a predetermined portion on the outer surface of the container body by mold processing;
Also, having a printed layer on which a pattern having a second regularity is printed on the outer surface facing the unevenness forming portion of the container body,
And, through the transparent container body, by the light interference effect by the pattern of the unevenness forming part and the printing layer, decorating with a three-dimensional visual effect,
It is in.

  According to the above-described configuration of the present invention, the unevenness forming portion having a pattern having a predetermined regularity and the printed layer are opposed to each other with a transparent container on the outer surface of the container wall. A visual effect is exhibited, a moiré pattern appears on the wall of the container, and the moiré pattern changes greatly with a slight change in the angle of the container body. In addition, by storing the transparent content liquid in this container, an unprecedented decoration effect is exhibited in combination with the prismatic effect of the content liquid. Even when the opaque content liquid is stored, the moire pattern appears intermittently every time the consumer consumes the content liquid, and the taste is added.

  Moreover, the pattern having the first regularity can be formed simultaneously with the molding of the container body such as blow molding or injection molding, and the pattern having the second regularity is usually used for screen printing, offset printing, etc. Both patterns can be formed on both the curved portions, for example, easily while ensuring a sense of unity with the container main body, and the above-mentioned 3 without adding a special process as a whole. The decorativeness due to the dimensional visual effect can be easily applied at low cost.

  The concavo-convex forming portion can be obtained by processing the cavity surface of the molding die so as to form a pattern having a predetermined regularity, or by performing processing such as blasting or embossing.

  Further, in the above configuration of claim 4, a colorless and colored transparent container main body can be used, and the cross-sectional shape of the container main body may be a shape having opposing surfaces such as a rectangle, a circle, The overall shape of the container main body is preferably a rectangular parallelepiped type, a drum type, or the like, but the opposing surfaces are parallel, but may be a cylindrical type, a cone type, or the like.

  The means of the invention described in claim 5 is the invention according to claim 4, wherein, in addition to the pattern having regularity, a pattern, a design, or a character is printed on at least one of the concavo-convex forming portion and the printing layer. It is in.

  According to the above-described configuration, the moiré pattern can be expressed so that a pattern, a design, a character, or the like appears on the back surface or sinks, and a more unique decoration or display effect can be exhibited.

  Here, in addition to the pattern having the predetermined regularity in claim 2 and claim 5, printing a pattern, a design, or a character is superimposed on the pattern having the predetermined regularity, Designs or characters may be printed. When a pattern having a predetermined regularity is formed by printing, a pattern having a predetermined regularity is printed in advance after a pattern, a design, or a character is printed. Alternatively, a pattern having a predetermined regularity and a pattern, a design, or a character may be printed at the same time.

The material of the synthetic resin container in the present invention is a polyester resin such as polyethylene terephthalate (hereinafter referred to as PET) resin, a polyolefin resin such as polyethylene resin or polypropylene resin, a polystyrene resin, an acrylic resin, or polyvinyl chloride. Can be used. The synthetic resin container can be obtained by hollow molding, biaxial stretch blow molding, injection molding, extrusion molding, thermoforming molding, or the like.

The present invention has the above-described configuration, and has the following effects.
In the first aspect of the invention, the first printed layer and the second printed layer can be easily formed by a normal printing method. For example, a sense of unity with the container body can be easily secured even in a curved portion. However, without adding a special process as a whole, the container can be effectively, easily and inexpensively decorated with a three-dimensional visual effect.

In addition, the first printed layer and the second printed layer, each of which has a predetermined regular pattern printed on the outer surface of the container wall, are opposed to each other with a transparent container interposed therebetween. The effect is exerted and a moire pattern appears on the wall of the container, and the moire pattern changes greatly with a slight change in the angle of the container body.
Further, by storing the transparent content liquid in the container main body, a decorative effect that has never been achieved is exhibited in combination with the prismatic effect of the content liquid. Even when the opaque content liquid is stored, the moire pattern appears intermittently every time the consumer consumes the content liquid, and the taste is added.
