BACKGROUND OF THE INVENTION
The present invention is used as a container for toothpaste, paint, cream-type squeezed cosmetics, etc., and is used for printing and varnishing on the surface, and for a tube container for a tube container that is partially foil-stamped. An object of the manufacturing method is to improve the quality by accurately aligning the printed portion and the foil.
[0002]
[Prior art]
For example, Japanese Utility Model Laid-Open No. 62-58697 discloses that a film printed with characters, designs, etc. is superimposed on a surface of a tube container, and is decorated. In addition, it has already been known to apply a metal foil or the like to a part of the printed portion of the above-described characters and designs.
[0003]
[Problems to be solved by the invention]
However, when applying a foil such as a metal to a part of the printing part, register the foil plate via the foil film to the printing part foil pressing planned place on the surface of the tube container on the foil stamping machine. In order to carry out the foil pressing operation, the foil pressing position is displaced from the predetermined position by the amount of deviation between the foil plate and the printing part due to the roll deviation of the original fabric or the variation in the feed pitch, and as a result, the foil pressing part is It overlaps with the printed part, or is too far away and the blank part is exposed, so that it does not look good. In particular, the more the pattern is intricate with the printed part, the more difficult it is to accurately determine the stamping position.
[0004]
[Means for Solving the Problems]
Therefore, in the present invention, the above-described problems in the prior art can be solved, and even if the pattern of the printed part is complicated, the foil can be stamped very accurately at a predetermined foil stamping location, and the quality of the tube can be improved. Specifically, the ink layer of the ultraviolet curable resin by printing a pattern, characters, etc., and the varnish of the ultraviolet curable resin covering the entire surface or a part thereof, except for the portion to be pressed with the foil. The present invention relates to a method for producing a tube container original fabric in which a layer is applied and foil pressing is performed at a location where the foil is to be pressed with a foil plate and foil film that are larger than the area where the foil is to be pressed.
[0006]
Coating in the configuration described above, subjected to a varnish layer of inks and UV-curable resin of the ultraviolet curing resin on the entire surface or a part except for the stamping planned portion, and the said foil press planned portion, a thermoplastic acrylic adhesive on the back surface to was such as to carry out the foil, the adhesive upon foil is to not adhere to the printing unit or the varnish, foils only stamping planned portion is subjected. In case of applying a foil to foil planned portion, in order to have to perform stamping with larger foil plate and foil film than the area of the stamping planned portion, performing a printing unit stamping of the tube container raw surface on stamping machine At this time, even when a large deviation occurs between the foil plate and the printed portion, sufficient foil pressing is performed by the large foil film, so that no gap is formed between the printing portion and the foil.

DETAILED DESCRIPTION OF THE INVENTION
In the following, the specific contents of the present invention will be described with reference to the illustrated embodiment. In FIG. 1, 1 is a tube container original fabric, 2 is a character or design applied to the surface of the tube container original fabric 1, etc. Ink layer by printing, 3 is a varnish layer coated on the ink layer, 4 is a place to be pressed with foil exposed on the surface of the ink layer 2 formed with the above printing, and 5a is a foil film Respectively. The tube container raw fabric 1 depends on the purpose of use, but for example, a basic sheet coated with a reactive or polymerizable curable resin on the surface thereof made of polyolefin, ionomer, ethylene-vinyl acetate copolymer, or the outermost layer. Made of polyethylene is used as the raw material.
[0008]
The ink layer 2 is preferably one containing an ultraviolet curable resin (acrylic UV ink), and the varnish layer 3 is also an ultraviolet curable resin that protects the ink layer and is excellent in friction resistance and content resistance. It is preferable that the same ink layer 2 as described above (for example, acrylic UV varnish) may be used. The foil film 5a used here is, for example, a polyester film as a base material, on which an aluminum vapor deposition layer is formed via a wax silicon release layer and an acrylic protective layer. An adhesive is used on the surface to form a so-called transfer mold. In addition, about the adhesive agent used here, use of a thermoplastic acrylic adhesive agent is preferable. By doing in this way, it adheres with the tube container original fabric which foil exposed on the surface, and does not adhere to the ink layer and varnish layer which consist of ultraviolet curable resin.
[0009]
An ink layer 2 is formed on the entire surface or part of the surface of the original fabric 1 except for the above-described planned foil pressing portion 4, and a varnish layer 3 is further formed on the upper surface thereof. In this case, the varnish layer 3 is formed on the ink layer 2 from the ink layer 2 portion, leaving a slight clearance P portion that does not form the varnish layer 3 with the outline of the portion 4 to be pressed as shown in FIG. If the varnish layer 3 is formed at a slightly retracted position, the outer edge portion of the ink layer 2 and the pressed portion can be adjacent to each other without any gap, which is preferable in terms of design. Further, by setting the clearance P portion to about 0.5 mm to 1.0 mm, the varnish layer 3 protects the ink layer 2 and does not adversely affect functions such as friction resistance and content resistance.
[0010]
The tube container original fabric 1 to which the ink layer 2 and the varnish layer 3 have been applied as described above is fed onto a known foil stamping machine (not shown), and the foil film 5a is accompanied with the foil stamping planned portion 4 on the surface of the tube container original fabric 1. The foil pressing operation for forming the foil 5 by applying pressure with the foil plate 6 and heating at a heating temperature of 100 to 120 degrees Celsius is performed. At this time, the foil film 5a does not adhere to the UV-curable resin ink layer 2 and the varnish layer 3 on which the thermoplastic acrylic resin adhesive on the back surface is overlapped. 5 is formed by adhering only to the area 4 to be pressed on the raw fabric 1. Note that FIG. 2 is an example of characters or designs when viewed from the tube container surface side, and the foil 5 is applied to the peripheral edge of the ink layer 2 made of characters along the characters by edge pressing. .
[0011]
Further, in this case, the size of the foil plate 6 and the foil film 5a described above is larger than the foil pressing planned location 4, and the foil pressing with the foil plate 6 and the foil film 5a larger than the area of the foil pressing planned location 4 is performed. Even when a large amount of misalignment occurs between the foil plate 6 and the foil film 5a and the planned foil pressing location 4 in the printing section when the stamping is performed on the surface of the tube container original fabric 1 on the foil stamping machine Since foil pressing is performed, there is no gap between the ink layer 2 and the foil 5 in the printing portion.
[0012]
【The invention's effect】
As described above, the present invention provides an ultraviolet curable resin ink layer and a varnish layer of an ultraviolet curable resin covering the entire surface or a part of the entire surface or a part thereof except for a portion to be pressed with a foil, Because it is a manufacturing method of the tube container original fabric in which the foil stamping is performed with a foil plate and foil film that are larger than the area of the foil stamping planned area, the printed portion of the surface pattern and characters as the tube container and the foil stamping Since there is no problem of so-called misalignment in which a gap is formed or overlaps with a portion, the product value can be improved beautifully. In this case, in particular, even in the case of complicated characters or designs with the printed portion and the foil pressing portion as shown in FIG. 2, the positional displacement of the foil pressing portion does not occur at all.
[0013]
In addition, when manufacturing the foil stamped tube container raw material, an ultraviolet curable resin ink layer and a varnish layer of an ultraviolet curable resin covering the entire surface or a part thereof are printed on the entire surface or a part thereof except for a portion to be foil stamped. At the same time, because the foil is applied to the back side via a thermoplastic acrylic resin adhesive, the adhesive is not adhered to the printed part or varnish when the foil is pressed. It is possible to obtain a tube container original fabric that has been subjected to high-quality foil stamping with no misalignment between the printing ink layer and the printing ink layer and the varnish overlapping part without being foil-bonded only at the location it can.
[0014]
In case of further performing foil to foil planned portion, in order to have to perform stamping with larger foil plate and foil film than the area of the stamping planned portion, performing a printing unit stamping of the tube container raw surface on stamping machine In this case, a large gap between the foil plate and the printed part will cause the foil to be pressed by the larger foil film, resulting in a gap between the printed part on the surface of the tube container and the foil. It is possible to obtain an extremely fine and beautiful tube container raw material.
