Description

[Detailed Description of the Invention] The present invention relates to a container made of synthetic resin, and its object is to securely attach a printed laminated film to the outer peripheral surface of the container.

On the outer surface of synthetic resin containers such as tube containers,
There is a need to apply product names, patterns, etc., and for this purpose, it is being considered to print directly on the outer circumferential surface of the container, or to wrap and adhere a printed label.

However, when directly printing on containers, the printing method is extremely difficult, and there is a major drawback that the printing is likely to peel off, especially on tube containers.

Furthermore, when the label is wound and adhered, it is necessary to adhere it strongly and firmly to the container, but this method is difficult, and the label itself is also easily peeled off, especially in tube containers.

Therefore, it has been considered to adhere a laminated film with a printed layer to the container, but this may cause problems such as cracks on the outer surface of the laminated film and staining of the printed surface during use, or the possibility that the film and the container may become stained. Dissatisfaction remained, such as incomplete adhesion and wrinkles.

Furthermore, when the laminated film is wound around a container, both ends are overlapped and bonded together, which is unsightly.

The present invention has been devised to eliminate the above-mentioned conventional drawbacks and inconveniences, and embodiments thereof will be described below with reference to the drawings.

The container of the present invention has a structure in which the outer periphery of a cylindrical container body 1 such as a tube container or bottle container made of a predetermined synthetic resin is coated with a laminated film 2 having a length equal to the outer circumference of the container body 1, Furthermore, this laminated film 2 is composed of a reinforcing layer 3 made of synthetic resin, a gravure or vapor deposition printing layer 4, and an adhesive layer 5 made of synthetic resin.

The reinforcing layer 3 is made of a transparent polyethylene terephthalate resin, polypropylene resin, etc., or a printed aluminum film coated with a resin, in order to sufficiently withstand external impact on the container. is also possible, but in this case the printed layer 4 is not necessary.

In either case, the outer surface of the reinforcing layer 3 is subjected to an antistatic treatment, and the inner back surface is subjected to an adhesive treatment.

Next, the printing layer 4 is formed by gravure, which is used in conventional transfer, or vapor deposition printing, and desired characters, patterns, etc. are attached thereto. In particular, in the case of vapor deposition printing, an anchor treatment is applied. It is necessary to keep it.

Further, the material of the synthetic resin adhesive layer 5 is selected depending on the material of the container body 1, which is the base.

That is, for example, when the container body 1 is made of polyethylene resin, the adhesive layer 5 is formed by laminating or coating polyethylene resin or Surlyn resin, and when the container body 1 is made of polyethylene resin and has an anchor coat attached, the adhesive layer 5 is formed by laminating or coating polyethylene resin or Surlyn resin. In this case, the adhesive layer 5 is formed by coating acrylic or acrylic urethane, and if the container body 1 is made of polypropylene resin, the adhesive layer 5 is formed by laminating or coating polypropylene resin or Surlyn resin.

Now, in the embodiment shown in FIG. 3 as a means for covering the container body 1 with the laminated film 2 having the above-mentioned structure, the long roll-shaped laminated film 2 is cut with a cutter A so as to have the same outer circumferential length as the container body 1. The laminated film 2 is cut into a fixed size, and the laminated film 2 is sandwiched between a hot roll B and the container body 1, and the laminated film 2 is wound around the outer peripheral surface of the container body 1 by rotating the hot roll B in a predetermined direction. It is melted and bonded.

As is clear from the above description, the container of the present invention has a structure in which a laminated film 2 is wound and bonded around the outer periphery of a container body 1. It is configured.

And the reinforcing layer 3 which is the outermost layer of the laminated film 2
is made of transparent polyethylene terephthalate resin, polypropylene resin, etc., so it can obtain sufficient strength that would be unimaginable with conventional UV coating, hot air drying coating, or no coating. You can clearly see through it, and by making it thicker, you can obtain a deeper beauty.

In addition, since the printed layer 4 is formed by gravure, vapor deposition printing, etc., the colors are vivid and can be displayed freely without being restricted by the shape of the container body 1, allowing for diversification in design. 3 is so strong that it will not be exposed to the outside, so there is no risk of it falling off.

Furthermore, since the adhesive layer 5 is formed of a material compatible with the molding material of the container body 1 serving as the base, it can be easily and reliably adhered to the container body 1.

Furthermore, since the laminated film 2 is cut to a fixed size to match the outer circumferential length of the container body 1, it can be rolled and bonded to the container body 1 with the peripheral edges in contact with each other. There is no overlapping, and the appearance is extremely good.

Therefore, according to the present invention, it is easy to roll and adhere the laminated film to the container body, it is possible to freely print any markings on the container, the outer surface is strong, the printing does not peel off, and the laminated film can be fixed to a fixed size. The present invention has many excellent functions and effects, such as the fact that the film is cut in half, so there is no variation in the film, and production is stable, and the container can also have a barrier effect by being covered with a laminated film.
