Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a tube container that exhibits a special printing effect and is capable of protecting the printing layer.

<Prior Art> Conventional tube containers have been decorated by offset printing, silk printing, or hot stamping with aluminum foil on the surface of the body.

<Problems that the invention aims to solve> However, with this method, the decorative surface is flat, making it difficult to express a sense of luxury, and it is necessary to apply a variety of decorations, which increases production costs. There were flaws.

On the other hand, in order to improve this drawback, a method was also implemented in which gravure printing was applied to a thermal transfer film coated with aluminum vapor deposition, and this was then thermally transferred to the body of the tube container. Although it has a deep multicolored pattern with a glossy finish, the transfer printing layer may peel off when the container is bent during use, or the transfer printing layer may peel off when containers such as cosmetics and pharmaceuticals are poured or capped. When attached to the printing layer, the aluminum vapor-deposited portion was chemically eroded and peeled off.

This invention seeks to provide a tube container that does not have any of the above-mentioned drawbacks.

<Means for Solving the Problems> The present invention provides a base coat layer made of synthetic resin on the surface of the body 2, which is made up of a tubular wall 5 made by mixing synthetic resin with fine powder made of non-ferrous metal such as aluminum or inorganic material such as titanium and mica. The present invention relates to a tube container constructed by laminating a transfer printing layer 7 consisting of an adhesive layer 8, a halftone printing layer 9, and a protective layer 10 in this order.

<Function> Since the present invention is constructed as described above, it is possible to make the surface of the body emit pearlescent light, and since there is no intervening aluminum vapor deposition layer, this layer is free from chemical erosion due to bending during use, etc. There is no peeling, and the body can be easily shaped by mixing non-ferrous metal such as aluminum or titanium-mica-based inorganic fine powder into the synthetic resin material fed into the extrusion shaping machine.

<Embodiment> An embodiment of the tube container according to the present invention will be specifically explained with reference to the drawings. In FIG. The tubular wall 5 of the body 2 is constructed by mixing fine powder of non-ferrous metal such as aluminum or titanium-mica-based inorganic material into a synthetic resin, as shown in FIG. The surface is configured to emit pearlescent light.

Next, 6 is a synthetic resin base coat layer applied to the entire outer surface of the tubular wall 5 of the body 2, thereby making the surface smooth.

Furthermore, 7 is a transfer printing layer, which is constructed by laminating and arranging an adhesive layer 8, a halftone printing layer 9, and a protective layer 10 in order from the inside.

Further, an overcoat 11 is applied to the surface of the transfer printing layer 7 for the purpose of protecting the printing layer 7.

FIG. 3 shows an embodiment in which the body 2 of the tube container 1 is made of two layers, and as described above, the tubular wall 5 is made of a non-ferrous metal such as aluminum or fine powder of titanium-mica-based inorganic material mixed therein. A general inner tubular wall 12 in which this kind of fine powder is not mixed on the inner surface is integrally laminated to form a double thick wall tube.

<Effects of the invention> As mentioned above, in the tube container according to the invention, the tubular wall 5 of the body 2 is mixed with fine powder of non-ferrous metal such as aluminum or titanium mica-based inorganic material. This allows the surface of the body to emit pearlescent light, and since the surface of this tubular wall is patterned with a halftone dot printing layer, the pearlescent light of the tubular wall is transmitted through the gaps between the halftone dots. Along with halftone dot printing, a special extremely heavy metallic luster pattern can be created to express a metallic high-class appearance, and unlike conventional methods, there is no aluminum vapor deposited layer, so this layer can be folded or stored during use. There is no risk of peeling due to chemical attack due to adhesion of objects, etc., and the body is made of non-ferrous metals such as aluminum or fine powder of titanium mica-based inorganic materials in the synthetic resin material fed into the extrusion shaping machine. Once mixed, it can be easily shaped, and transfer printing layers such as halftone dot printing can be extremely easily laminated onto the surface of the fuselage by thermal transfer.
It has characteristics such as being able to be mass-produced at low cost.
