Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has a decorative layer and a transparent outermost protective layer through which the decorative layer can be seen. Regarding the hose used.

In recent years, hoses used in homes and the like have come to be required not only to fulfill their functions as hoses and to be robust and durable, but also to have a rich appearance.

However, conventional hoses are generally manufactured by extrusion molding of plastics such as rubber, polyvinyl chloride, and polyethylene, and most of them are formed as a single layer of a single material. In addition, these hoses have the disadvantage that they are not strong enough, crack etc. occur in a relatively short period of time, and are not long-lasting and are inferior in durability.In addition, the color tone of the material itself directly appears in these hoses, and they are usually formed in a single color. Because of this, it has the disadvantage of being unsightly and lacking in aesthetics. In addition, a two-layer hose is also available in which the hose body is formed by extrusion molding, and a rubber or glass material with an appropriate color tone is layered and extruded to cover the hose body f. Although this has a certain degree of robustness, this two-layer hose also has the disadvantage that the surface layer is usually a single color and is decoratively simple.

Conventionally, a known method for forming a pattern on the surface of a hose is to print directly on a portion of the surface of the hose, but it is extremely troublesome to form a pattern on the entire surface of the hose using the printing method. Shi, shikaka designs are also limited. That is, when printing the outer circumference of the hose by white printing, copying, etc., it is difficult to print the entire outer circumference at once;
For this reason, one side has a metal cylinder of 180' to 1200',
Next, it is desirable to print in two or three steps by cylindriving the remaining part, but this method is complicated, tends to cause print misalignment, and makes it difficult to compare the print pattern. It tends to be simple. Furthermore, the knurling and spiral printing methods also limit the colors and produce simple patterns. Furthermore, it is possible to adopt a multicolor printing method to print patterns on hoses and incorporate them into continuous molding of hoses, but this would require very bulky equipment and would increase costs considerably. This is not practical as it would invite

The present invention has been made in view of the above circumstances, and it is decorated, is highly aesthetically pleasing, does not contaminate the decorative part, is strong and durable, and can be manufactured easily and inexpensively. The purpose is to provide hoses.

That is, in order to achieve the above object, the present invention includes a hose main body made of rubber or plastic as the innermost layer, a decorative layer formed on the outside thereof, and a protective layer having transparency that allows the decorative layer to be seen through the decorative layer. It is formed as the outermost layer covering the

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a hose 1 according to an embodiment of the present invention, in which a hose body 2 is the innermost layer, and a decorative layer 4 is formed on the outside through an adhesive layer 3 on the entire outer peripheral surface of the hose body 2. In addition, a protective layer 6 having transparency that allows the decorative layer 4 to be seen through is laminated on the entire outer peripheral surface of the intermediate layer 5 as the outermost layer covering the decorative layer 4. be.

Here, the hose body 2 is made of rubber or polyvinyl chloride,
It can be made of plastic such as polyethylene. Further, the intermediate layer 5 is formed of a polyethylene film, a plastic film such as polyvinyl chloride, cloth, etc., and the decorative layer 4 having an appropriate pattern can be formed on the surface thereof by printing.

Furthermore, the protective layer 6 can be made of transparent plastic, such as polyethylene, polypropylene, etc.

The protective layer 6 needs to have a transparency that allows the pattern layer 4 to be seen through, but it is not limited to being colorless and transparent, but may be colored and transparent, or may be partially transparent.

Next, an example of a method for manufacturing the hose 1 will be described. First, all known hose extrusion molding methods are adopted, and as shown in FIG. A hose body (inner tube) 2 is continuously molded by a hose molding device A made of lO. Next, this hose body 2 is guided to a film laminating device B, and a film 5 is
21 laminate a. That is, the adhesive is applied to the outer circumferential surface of the hose body 2 by the application device 11, and then the excess adhesive is removed by the wiping device 12 to achieve a uniform application state. On the other hand, a decorative layer is formed in advance by printing a desired pattern, and a film 5a cut to a predetermined width is fed out through a feeding device 13 and guided to a guide shooter 14, where a wiping device 12 is removed. The passed hose main body 2 and the film 5& are continuously laminated (in this case, the pattern decoration layer of the film 5a is placed on the outside). Further, this laminate 15 is guided to a shearing device 16, where the film 5a is completely adhered to the film 5a without wrinkles, and then taken off by a second take-off machine 17.

Finally, a known extrusion covering molding method is adopted for the laminate 15 of the hose body 2 and the patterned film 5a, and an extrusion cover consisting of an extruder 18, a mold 19, a cooling water tank 20, and a third take-off machine 21 is formed. The laminate 15 is introduced into a mold 19 of a ring molding device C, and the film 5a is
A transparent protective layer is coated and molded on top of the sheet hose main body 2 as the innermost layer, and a film 5 on which a pattern is formed.
A hose 1 is obtained in which a is the middle layer and the transparent protective layer is the outermost layer.

In this case, the film 5a forming the intermediate layer can cover the hose main body 2 in a cylindrical shape, but may also be coated in a spiral shape as the case may be. Also,
The adhesive used for laminating the film 5a on the hose body 2 is not particularly limited, but a hot melt adhesive is most preferred in terms of odor. In addition, when a hot melt adhesive is used, the adhesion is achieved by utilizing the temperature at the time of forming the protective layer (the mold 15 of the covering molding device C), thereby developing the original adhesive strength. Furthermore, a solvent can be used as an adhesive for adhering the film 5a to the hose body 2.

In the above-described hose 1, since the intermediate layer 5 having the patterned decorative layer 4 is covered with a transparent protective layer 6, the decorative layer 4 can be seen through from the outside. Since it is decorated with a pattern rather than a single color, it has a very good appearance and is highly aesthetically pleasing. Moreover, in this case, by employing the above-mentioned hose forming method, it is possible to use a film with a pre-printed pattern formed on it, so that the patterning on the hose can be done easily and inexpensively, and it can also be done without complicated Alternatively, various interesting patterns with rich colors can be selected and formed, and a desired pattern can be easily formed around the entire circumference of the hose.

In addition, since the intermediate layer 5 is laminated on the hose body 2 and the transparent protective layer 6 is formed covering the decorative layer 4, it is durable and the pattern will not get contaminated or disappear. However, it has excellent wear resistance and crack resistance, and has good durability that can withstand long-term use. Further, the material of the hose body 2 is not limited by decoration, and the material can be freely selected, and durable materials can be used.

In the above embodiment, the hose body 2 is laminated with the decorative layer 4 formed on the outside of the intermediate layer (film) 5, and the protective layer 6 is further laminated. It is also possible to form a printed pattern layer on the hose body and to adhere the pattern layer to the hose body. In this case, the transparent film layer is configured as a protective layer. Furthermore, in the above embodiments, a pattern was formed as a decorative layer, but if the intermediate layer is colored by adding a pigment or the like, the intermediate layer may be colored by a printing method or by attaching a film of an appropriate color to the intermediate layer. The colored intermediate layer and the colored layer made of a print or film can be formed as a decorative layer. In this case, even if these colored layers are of a single color, a transparent protective layer is formed thereon, so that the colored intermediate layer and the colored layer made of a print or film can be formed as a decorative layer. Compared to solid color hoses, they have more interesting decorations.

Furthermore, the method of manufacturing the hose is not limited to that shown in FIG. 2, and other configurations may be modified in various ways without departing from the gist of the present invention.

As explained above, the present invention has a hose main body made of rubber or plastic as the innermost layer, and a decorative layer is formed on the outside thereof, and the decorative layer is covered with a protective layer having a high degree of transparency that allows the entire decorative layer to be seen through. Since it is formed as the outermost layer, it has a decorative appearance, so it looks good and is aesthetically pleasing, and the decorative layer also prevents contamination.
It does not get dirty, is strong and extremely durable, can be easily and inexpensively manufactured, and is suitable for household use.
