Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a synthetic resin tube container, and is intended to give a soft and warm texture to the appearance of the tube container. .

"Prior art" A tube container molded from a synthetic resin material such as polyethylene resin has excellent flexibility, content resistance, chemical resistance, tensile strength, etc., and is inexpensive and easy to manufacture. One of the major features of this synthetic resin tube container is that it can be used and is excellent in workability, and its surface is extremely smooth, which makes it difficult to stain and, for example, stains adhere to it. However, it was able to be easily wiped off, and a glossy appearance could be obtained.

As described above, the conventional synthetic resin tube container has one feature that its outer surface is extremely smooth, and therefore, its appearance is glossy and hard,
It had a cold feeling and could not obtain a soft and warm appearance like Japanese paper at all.

Therefore, there has conventionally been a tube container that has been subjected to color decoration and surface treatment so as to give the appearance a little softness and warmth.

"Problems to be solved by the invention" However, the effects described in the related art are not sufficiently effective in appearance, and the touch feeling when actually touched with a fingertip is completely soft and warm. There was nothing, and I was completely dissatisfied with the texture.

In particular, recent tube containers are now required to have light, soft, and warm decorations because of their shiny decorations that are mainly metallic. However, there is a problem in that the appearance of a tube container capable of responding to the actual situation strongly desired has not been provided.

The present invention has been made in view of the above problems of the prior art, and its purpose is to provide a polyethylene resin or the like that can effectively exert a light, soft, and warm decorative effect. An object of the present invention is to provide a tube container formed of the synthetic resin material of.

[Means for Solving Problems] In order to achieve the above-mentioned object, the synthetic resin tube container in the present invention is configured by effectively combining the softness and the matting effect of the foamed resin. Referring to the drawings, the synthetic resin tube container according to the present invention, like the conventional synthetic resin tube container, has a body portion 1 whose lower end is tightly and firmly sealed, and a body portion 1 of the body portion 1. It is composed of a head 8 which is connected to the upper end and forms an extrusion.

The body portion 1 includes a tube body 2 having a laminated structure of an inner layer 3 and an outer layer 4, a print layer 5 and a coat layer that are sequentially laminated and formed on the outer peripheral surface of the tube body 2, that is, the outer peripheral surface of the outer layer 4. 6 and 6.

The tube body 2 is directly formed into a cylindrical shape by extruding the inner layer 3 and the outer layer 4 integrally by coextrusion in a state where only the outer layer 4 is foamed.

The print layer 5 is formed by printing on the outer peripheral surface of the outer layer 4 by offset printing or the like, and has a desired pattern such as a pictorial pattern drawn in a light color tone as a ground pattern.

The coat layer 6 is formed by coating the outer peripheral surface of the outer layer 4 with a gradation mat coat in which a silica-based substance is added and dispersed in a coat liquid.

The pattern shape of the printed layer 5 that forms the ground pattern should be set according to the texture that the tube container according to the present invention is intended to reveal, and may be a solid paint of a single color in some cases.

"Function" The outer peripheral surface of the tube body 2, that is, the outer peripheral surface of the outer layer 4, the print layer 5 laminated and molded, and the outer surface of the outer layer 4 and the coat layer 6 protecting the print layer 5 are extremely thin. In addition, since it is sufficiently soft, the softness of the outer layer 4 is exposed as it is on the outer surface of the body 1, and therefore the outer peripheral surface of the body 1 is extremely soft to the touch. Becomes

Further, since the foam-molded outer layer 4 has extremely poor heat transfer due to its structure, even if the printing layer 5 and the coat layer 6 are located on the surface, the outer layer 4 does not adhere to the surface of the body portion 1. It does not mean that the heat of the contacted article is taken away within a short period of time, which makes it possible to obtain a warm tactile sensation when contacted with a fingertip.

Further, since the coat layer 6 has a matte function, it is possible to eliminate the gloss of the surface of the coat layer 6 as compared with the case where the outer layer 4 is simply exposed, thereby providing a warmer appearance. In addition to being obtainable, it has a surface shape that is extremely slippery due to matting and has a large number of irregularities, which makes it difficult to slip, which makes it easy to handle with a fingertip.

Then, a coat layer is formed by coating on the outer peripheral surface of the outer layer 4 which is sufficiently soft but has a very weak surface mechanical strength, and the coat layer 6 functions as a protective coating, so that the tube having a high surface abrasion strength is formed. The container can be obtained.

[Example] An example will be described with reference to the drawings.

The tube container of the present invention is molded in the following order.

First, the inner layer 3 and the outer layer 4 are coextruded together in a state where fine particles of the resin material forming the outer layer 4 are foamed to extrude the tubular body 2 having a cylindrical shape.

After the extruded tube body 2 was cut into a certain length, a printing layer 5 was formed on the outer peripheral surface of the tube body 2 by means of offset printing or the like, and then this printing layer 5 was formed. The coat layer 6 is formed on the outer peripheral surface of the tube body 2 by roller coating or spraying so as to cover the entire outer peripheral surface, and the body portion 1 is completed by drying and solidifying the coat layer 6.

After the body portion 1 has been molded, the head portion 8 is integrally joined to the body portion 1 by the same means as in the conventional tube container molding method to complete the molding of the tube container.

The embodiment shown in FIG. 1 shows the most basic constitution of the tube container according to the present invention, and is particularly constructed so as to bring out the appearance imitating Japanese paper.

In the case of the embodiment shown in FIG. 1, it is preferable that the printing layer 5 draws a translucent picture pattern in a light color tone according to the appearance of Japanese paper, and the color tone is also a neutral color and has a soft texture. It is desirable to form a pattern.

The coating layer 6 is required to have a stronger matte, but according to the results of many experiments and observations, the amount of the silica-based substance added to 100 parts of the coating liquid is 7%.
It was found that the mat effect and workability were the best when the ratio was set to 12 to 12.

In particular, in the case of Japanese paper, the surface thereof has a rough texture and is hard to slip, but when the surface of the body portion 1 is directly formed by the outer layer 4, it is possible to form a soft and appropriately finely uneven surface. However, it is slippery despite the unevenness, and it is not possible to obtain a non-slip surface like Japanese paper.

When the surface of the outer layer 4 is coated with the coat layer 6, finer unevenness is formed on the unevenness formed on the surface of the outer layer 4, and the unevenness makes the surface slipperiness equivalent to that of Japanese paper. Obtainable.

The embodiment shown in FIG. 2 is formed to imitate a leather or a woven fabric, and in addition to the structure shown in FIG. 1, an uneven pattern 7 by embossing is further formed on the outer surface of the body 1. It is molded.

The uneven pattern 7 is an uneven pattern that resembles pores or wrinkles on the skin when it is desired to imitate a leather, and an uneven pattern that resembles the texture of a fabric when it is desired to imitate a woven fabric.

When it is desired to make the outer appearance of the body 1 resemble "skin", the amount of the silica-based substance added to the coating liquid in the gradation mat coat for forming the coating layer 6 is sufficiently larger than that in the case of Japanese paper and fabric. It goes without saying that the slipperiness on the outer surface of the body 1 is made equal to that of "skin".

A product name, a mark, or a product description may be printed on the coat layer 6 by a hot stamp or the like. In this case, the pattern printed by this hot stamp will be visible in a raised state.

“Effect of device” As described above, since the synthetic resin tube container according to the present invention can obtain the soft and warm appearance and texture, it is possible to obtain the appearance decoration imitating Japanese paper, leather and fabric. This makes it possible to exert a completely new decorative effect that has never existed before.

Further, since the structure is simple and the molding can be carried out by using the conventional molding method as it is, it can be carried out easily and surely.
