Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an algae-proof hose in which algae and the like are not generated.

[0002]

2. Description of the Related Art In the case of a watering hose for the garden, water is often stored in the hose. However, tap water in general contains bacteria that are a source of algae. Further, when the water stored in the aquarium is used as tap water, algae may be generated in the aquarium. In such a situation, if the hose in the water is left outdoors, the algae may grow under the action of sunlight. In particular, in the case of a vinyl chloride hose that easily transmits sunlight, the algae grows significantly.
If too much algae occurs in the hose, for example, when a nozzle with many small holes is attached to the end of the hose, the small holes will be blocked by the algae and the function of the nozzle will be impaired. Be done. Therefore, in the conventional vinyl chloride hose, the hose has a multi-layer structure of an inner tube and an outer tube, and the inner tube is black so that sunlight cannot easily pass therethrough.

[0003]

In a conventional hose having an inner tube provided with a light-shielding layer of a dark color such as black, for example, when the outer tube is a transparent material colored,
Sometimes the dark black color of the inner tube appeared on the surface, impairing its appearance. In addition, the inside of this hose was also a black inner tube, so the black color of the inner tube was completely visible from the end face of the hose, so the impression was very bad. further,
Since the hose made of vinyl chloride does not slide very well, impurities such as dead algae dead bodies and various bacteria accumulated in the hose adhere without being discharged, but this impurity becomes a resistance,
There were times when it made the flow of water worse. Furthermore,
Molds and the like were also generated in the hose, but when the water was drunk, the molds and the impurities mentioned above sometimes caused discomfort to the person who drank it. An object of the present invention is to provide an algae hose that does not allow the dark color of the light blocking layer to enter the eyes of the user and is not affected by impurities or germs.

According to the first aspect of the present invention, in an algae hose comprising an inner tube composed of a plurality of layers and an outer tube covering the inner tube, the inner tube has an outer side of a light shielding layer colored black or the like. It is characterized in that it is covered with a color permeation preventive layer that prevents color permeation, and that this color permeation preventive layer is covered with an outer tube. In the invention according to claim 2, the inner tube has a three-layer structure, and the innermost layer and the outermost layer thereof are color transmission preventing layers such as white and are sandwiched between these color transmission preventing layers. The feature is that the intermediate layer is a light blocking layer that is colored black or the like. The invention according to claim 3 is characterized in that a lubricant such as silicon is applied or mixed into the innermost layer of the inner tube. The invention according to claim 4 is characterized in that an antibacterial agent is applied or mixed into the innermost layer of the inner tube. The invention according to claim 5 is characterized in that an antibacterial agent and a lubricant such as silicon are applied or mixed in the innermost layer of the inner tube.

[0005]

Since the present invention is constructed as described above, the dark color of the light blocking layer does not appear on the surface of the outer tube or the innermost layer of the inner tube. Further, since the innermost layer of the inner tube contains the lubricant and the antibacterial agent, impurities such as dead algae in the hose and various bacteria do not adhere to the inner surface of the hose, and the occurrence of mold and the like can be prevented.

[0006]

According to the algae hose of claim 1, since the dark color light blocking layer is covered with the color transmission preventing layer,
Even if the outer tube is made of a transparent material, the dark color of the light blocking layer does not make the hose look bad. While achieving the objective of anti-algae, a hose with a transparent feeling can be obtained, so that high added value of the product can be achieved. In particular, when a reinforcing thread is wound around the outer side of the light blocking layer, the thread can be seen through the outer tube, so that it can be expected to have a higher added value. According to the algae preventive hose of claim 2, since the color permeation preventive layer is provided on the innermost side of the inner tube, the dark light blocking layer is not visible on the inner surface of the hose, which improves the impression. At the same time, high added value can be achieved.

According to the third aspect of the algae-proofing hose, since the lubricant such as silicon is applied to or mixed with the innermost layer of the inner tube, the hose inner surface slides well, and dead algae and various germs can be prevented. It is discharged without impurities attached. Therefore, unlike the conventional case, the flow resistance of the hose is not increased due to these impurities. In addition, this lubricant such as silicon is more economical because it needs to be applied or mixed only in the color permeation preventive layer in the innermost layer. Since the antibacterial agent is applied or mixed in the innermost layer of the inner tube, the algae-proof hose according to claim 4 is free from mold and the like in the hose. Therefore, even if the user drinks the water, no discomfort such as musty odor will be felt. Also in this case, applying or mixing the antibacterial agent is
It is economical because it requires only the color permeation preventive layer. According to the algae hose of the fifth aspect, not only impurities such as carcasses of algae and various bacteria do not adhere, but also mold does not occur.

[0008]

[Example] The illustrated embodiment is a vinyl chloride hose,
The inner pipe a is covered with the outer pipe b, but the inner pipe a has a multi-layer structure. That is, the inner tube a has a structure in which the surface of the black light blocking layer 1 and the inner surface thereof are covered with the white color transmission preventing layers 2, 3, 3.
While being covered with, the outer surface of the color permeation preventive layer 2 is wound with a polyester-based reinforcing yarn 4. An antibacterial agent and a lubricant such as silicone are mixed in the color permeation preventive layer 3 on the inner side. The outer side of the inner tube a as described above is covered with the outer tube b colored with a transparent material.

Since the hose of this embodiment is constructed as described above, the black color of the light blocking layer 1 is hidden by the white color transmission preventing layers 2 and 3 and does not appear on the surface or the inner surface of the hose. . Therefore, the aesthetics of the outer tube b colored with a dark black and transparent material of the light blocking layer 1 is not impaired. Also,
Since the reinforcing thread 4 is wound around the outer color permeation preventive layer 2, this thread can be seen from the transparent outer tube b. The hose around which the reinforcing thread 4 is wound has a high strength, and the added value of the product is increased accordingly. However, since the hose can be seen from above the outer tube b, the user also has a high added value with sufficient strength. You can purchase while confirming that it is a product.
In addition, the method of winding the reinforcing yarn 4 also has a pattern on the surface of the hose, which makes it possible to achieve higher added value.

Further, since the inner color permeation preventive layer 3 is mixed with a lubricant such as an antibacterial agent or silicone, the inner surface of the hose is slippery better, and not only fungus does not occur, but also dead algae and Impurities such as bacteria are not attached and are discharged. Therefore, the water does not have a musty odor, and the flow resistance of the hose is not increased due to the impurities. Moreover, these antibacterial agents and lubricants such as silicone are
It is more economical because it needs to be mixed only in the color permeation preventive layer in the innermost layer.

In the above embodiment, the color transmission preventing layers 2 and 3 are provided both on the outer side and the inner side of the light blocking layer 1. However, if only the appearance of the hose is a problem, the color of the outer side is not affected. Only the permeation preventive layer 2 may be used. When only the outer color transmission preventing layer 2 is formed in this way, an antibacterial agent or a lubricant is mixed in the light blocking layer 1. Further, in this embodiment, the antibacterial agent and the lubricant are mixed together, but they may be used alone. Furthermore, it goes without saying that they may be directly applied to the inner surface of the hose without being mixed.
