本考案は、車輌用窓洗浄装置における洗浄液タ
ンクに関する。[Detailed Description of the Invention] The present invention relates to a cleaning liquid tank in a vehicle window cleaning device.
従来のこの種の洗浄液タンクは、硬質材料より
成るものと、軟質材料より成るものとがある。 Conventional cleaning liquid tanks of this type include those made of hard materials and those made of soft materials.
硬質材料より成るものは、ポリエチレンを用い
てブロー成形により横断面円形に近似する中空状
に成形されている。 The one made of a hard material is blow-molded using polyethylene into a hollow shape having an approximately circular cross section.
この場合、タンク本体に洗浄液の注入口、注出

体内で共鳴してその騒音が増幅されてしまうとい
う問題がある。 In this case, it has the advantage that the cleaning liquid inlet, outlet, pump mounting part, etc. can be integrally molded into the tank body, but since it is made of a hard material that hardly deforms, the tank body can be easily molded due to the vibration of the power source. Noise is generated by vibrations, and especially because the tank body is hollow with a cross section that approximates a circle, as the amount of cleaning liquid in the tank body decreases and the hollow area increases, the noise caused by the vibrations resonates within the tank body. There is a problem in that the noise is amplified.

避けられなかつた。 In addition, although items made of soft materials do not have the noise problem of those made of hard materials as mentioned above, they are generally formed into a bag by stacking two flexible sheets such as vinyl chloride and welding the edges. Because of this structure, the inlet, outlet, pump mounting part, etc. cannot be integrally formed, and these must be attached by separate processing, resulting in high processing costs.Also, as mentioned above, the two pieces of Since the edges of the flexible sheets are welded to form a bag shape, the tank body is made up of two flexible sheets that are tightly attached to each other over the entire surface of the tank after all the cleaning liquid has been poured out. This has caused problems such as difficulty in injecting the next time. For this reason, in the case of a cleaning liquid tank with this type of configuration, for example,
-26630, measures such as providing an air passage forming means in the tank to prevent the tank wall from coming into close contact with the tank wall when the tank is crushed and to allow the lower part of the tank to communicate with the atmosphere are taken. However, in such conventional devices, the air passage forming means must be provided separately within the flexible tank, making the molding process difficult and inevitably increasing costs.

形したことを特徴とするものである。 The present invention was developed in view of the above circumstances, and it produces less noise due to the vibration of the tank itself.
In addition, it can be easily installed in a narrow space with equal width between the walls of a vehicle, and even if the cleaning liquid is almost completely poured out and the opposite side walls come into contact with each other, both side walls are in close contact with each other over the entire surface. The purpose of the present invention is to provide a cleaning liquid tank for a vehicle window cleaning device that allows the next injection to be carried out smoothly without overflowing during the process. The pair of opposite side walls made of thermoplastic resin has a flat hollow shape in which the peripheral edge portions are closed by peripheral side walls having a substantially U-shaped cross section, and even when the peripheral side wall portions are brought into close contact with each other, the above-mentioned Tank body 2 formed so that a hollow part is held in the peripheral side wall part
The tank body 2 is characterized in that the inlet 5 and the outlet 6 provided in the peripheral wall portion of the tank body 2 are integrally formed by blow molding.

Then, as the nozzle attached to the front or rear window of the vehicle is used, the cleaning liquid in the tank body 2 is sequentially poured out by the power source 11 through the spout 6 and the discharge pipe 13 and reduced. When all the cleaning liquid in the tank body 2 has been poured out, both side walls of the tank body 2 come into close contact with each other, but a hollow part is maintained in the circumferential side wall, so that the next cleaning liquid cannot be injected. It is something to wait for.

気通路形成手段を設ける必要がなく安価である。 As mentioned above, in the cleaning liquid tank according to the present invention, since the tank body 2 is formed of a soft thermoplastic synthetic resin with a hardness of Shore A20 to 99, the vibration of the tank itself is more It produces less noise due to
It can be easily installed in narrow spaces such as between the sides of a vehicle. Furthermore, even if all the cleaning liquid in the tank body 2 is poured out, for example, and the both side walls of the tank body come into close contact with each other, the hollow part remains in the circumferential side wall part, so it is not possible to use conventional soft materials. When the cleaning liquid is injected from the injection port 5, the cleaning liquid goes into the hollow part of the peripheral side wall and from the peripheral edge of both side walls to the contact area of the both side walls. Not only can the cleaning liquid be poured smoothly by peeling it off, but even if the cleaning liquid decreases due to pouring out and abutting parts are formed on both side walls, it will not be able to flow through the hollow part of the peripheral side wall. The cleaning liquid can be poured out smoothly, and there is no need to provide special air passage forming means within the tank body, making it inexpensive.
