[Industrial applications]

 The present invention relates to a synthetic resin hose having a desired marking such as a trade name, size, company name, brand name, or measuring mark on the outer surface of a synthetic resin hose.

[0002]

[Prior art]

 Conventionally, this kind of synthetic resin hose has a different color from that of the hose (for example, a black hose is marked on a blue hose), and the desired marking such as a company name or brand name is provided on the outer surface of the hose. It was done by gravure printing or offset printing.

[0003]

[Problems to be solved by the device]

 In particular, for synthetic resin hoses of recent years, measuring marks for cutting are to be provided at regular intervals in the length direction of the outer surface of the hose. Is used as a mark. However, in conventional synthetic resin hoses, the marking is printed in a color different from the color of the hose, as described above.Therefore, the marking may be different depending on the size, thickness, or color of the ink. It may be difficult to see, and as a result, for example, if you miss or make a mistake in the desired measuring marking, you may accidentally cut it, or it may take time to detect the marking and the cutting work may not be performed smoothly. It was Moreover, in the case of a transparent synthetic resin hose in which the fluid can be confirmed, there was a strong problem that the marking became more difficult to see.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a hose made of a synthetic resin that clearly shows a desired marking on the outer surface of the hose. Is to provide.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the technical means made by the present invention is to form a linear strip on the outer surface of the synthetic resin hose body in the longitudinal direction, the marking layer having a color different from that of the body and made of the same material. That is, the markings were embedded integrally and the markings of different colors were provided on the marking layer.

Further, the hose body made of synthetic resin is transparent.

The color of the marking layer and the color of the marking ink have a dark-light color relationship.

Further, the hose body made of synthetic resin is transparent, and the color of the marking layer and the color of the marking ink have a dark and light color relationship.

[0009]

[Action]

 By the above-mentioned technical means, the marking layer embedded in a linear band with a color different from that of the hose body allows the marking position to be recognized linearly. Further, since the marking layer is provided with a marking different in color from the marking layer, the marking is clearly recognized. Further, if the color of the marking layer and the color of the marking ink have a shade relationship, the marking becomes particularly clear and easy to recognize.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In the figure, A shows an example of the synthetic resin hose of the present invention. The synthetic resin hose A is made of, for example, a soft vinyl chloride resin as a main raw material, and conventionally known additives are mixed in a desired ratio. It is composed of a hose body 1 made of a soft vinyl chloride resin having a desired inner diameter and an outer diameter formed by blending, and a marking layer 2 provided in the outer surface length direction (axial direction) of the hose body 1, both of which are extruded. It is integrally molded.

The hose body 1 is not particularly limited in its inner diameter and outer diameter as long as it is a well-known pipe made of a synthetic resin having a wall thickness capable of embedding a marking layer 2 described later, A well-known structure such as a coil internally provided as a reinforcing material or a structure including an inner tube and an outer tube can be applied, and it may be transparent, semi-transparent or opaque. The color can also be set arbitrarily. Further, in the present embodiment, a soft vinyl chloride resin is used for explanation, but it may be made of another soft resin material, which is also applicable.

The marking layer 2 is integrally embedded in a straight band shape with a predetermined width in the length direction of the outer surface of the soft vinyl chloride resin hose body 1. In order to maintain the flexibility and flexibility of the hose body 1, it is made of the same soft vinyl chloride resin as that of the hose body 1 and has a color different from the color of the hose body 1 and on the marking layer 2. It should be of a different color than the desired marking 3 ink applied.

The color of the marking layer 2 and the color of the ink of the marking 3 are not particularly limited as long as they are different colors, but it is preferable that the two have a shade relationship, for example, the marking layer 2 is white (light color). In this case, it is preferable to provide the marking 3 with black or red ink or the like (dark color) so that the marking 3 can be clearly seen. In contrast to the above example, the marking layer 2 may be dark and the marking 3 may be light. Other than the above example, the relationship between the marking layer 2 and the marking 3 is, for example, white (light color) with respect to blue, green, or the like (light gray), light gray, light blue, light green, light pink, light yellow. For (light color), black, red, blue and the like (dark color) as described above and combinations thereof are arbitrary, and changes and selections within the scope of the present invention are possible.

Here, as an example of a specific relationship between the hose body 1 and the marking layer 2 and the marking 3, for example, when the hose body 1 is transparent, the marking layer 2 can be white or fluid can be confirmed. It is semi-transparent (light color) of about white, and the marking 3 is provided on the marking layer 2 with black or red ink (dark color). The above specific example is merely an example and not limited thereto. For example, the hose body 1 is black, the marking layer 2 is light gray (light color), and the marking 3 is black (dark color). Modifications and selections are possible within the scope of the present invention. In the above-mentioned examples, the marking ink is particularly preferably black.

The embedding depth and width of the marking layer 2 can be set arbitrarily and are not limited, and in the illustrated example, only one is provided so as to be orthogonal to the outer circumferential direction of the hose body 1. It is also arbitrary to provide a plurality of lines at arbitrary intervals, and in the case of a plurality of lines, the width, depth, etc. of each may be changed, which can be appropriately dealt with.

The marking 3 provided on the marking layer 2 may be any desired character or symbol such as a trade name, a company name, a brand name, or a scale marking, and the gravure is used as a printing method. Well-known methods such as offset, hot stamping, and inkjet are applicable and are not limited.

Further, in the present embodiment, the line portions 4 having different colors from each other along the lengthwise both side edges of the marking layer 2 are also different from the hose body 1 and the marking layer 2. , 5 are integrally provided by extrusion molding together with the hose body 1 and the marking layer 2, so that the marking 3 can be seen more easily and the twisting of the hose at the time of mounting can be more effectively confirmed.

[0019]

[Effect of device]

 Since the present invention has a unique configuration as described above, the marking layer embedded in a linear band with a color different from the color of the hose body makes it easy to find the marking position because the marking position is recognized linearly. Since the marking is provided in a color different from that of the marking layer, the marking is clearly recognized, and the marking may be difficult to see due to the size and thickness of the print, as with conventional hose made of synthetic resin. Therefore, it is possible to provide a synthetic resin hose that clearly shows a desired marking such as a company name, a brand name, and a marking marking on the outer surface of the hose. Further, since the marking layer is made of the same material as the hose body and is integrally embedded in the outer surface of the hose body, there is no fear of impairing the pressure resistance and flexibility of the hose.

Therefore, the problem of oversight of the measuring marking, which is a mark at the time of cutting, or cutting at an incorrect position due to a mistake, which is a problem in the prior art, can be sufficiently solved, and the marking position can be surely secured. In addition, quick confirmation can be performed and cutting work can be speeded up. These are particularly effective in a hose made of transparent synthetic resin, which is difficult to see the markings in the past.

Further, in particular, when the color of the marking layer and the color of the marking ink have a shade relationship, the marking is clearly represented on the marking layer, and the above-mentioned respective effects are most effectively exhibited. .

Further, according to the present invention, since the marking layer is integrally embedded in a straight line shape with a predetermined width, the twisting of the hose can be easily confirmed by the marking layer without twisting. The hose can be attached.
