[Modes for carrying out the invention]

[0009] The following description of the rust converter application container according to an embodiment of the present invention will be given with reference to the drawings. Figure 1 is a diagram of the rust converter application container according to an embodiment of the present invention, where (a) is a side view, (b) is a longitudinal cross-sectional view of the state in (a), and (c) is a longitudinal cross-sectional view obtained by rotating (b) by 90° around the axis. Figure 2 is a perspective view of the tip of the rust converter application container according to the embodiment.

[0010] The rust converter application container 2 comprises a shaft 10 having a cylindrical structure that is long in the axial direction and has a stepped, narrowed diameter at its tip, an application body 12 attached to the tip of the shaft 10, a storage section 13 installed inside the narrowed diameter of the shaft 10, a rust converter tank 14 installed inside the shaft 10, and a cap 16 covering the application body 12.

[0011] Figure 3 shows the shaft 10 of the rust converter application container 2, where (a) is a perspective view from the front, (b) is a side view, (c) is a longitudinal cross-sectional view of the state in (b), (d) is a side view of (a) rotated 90° around the axis, (e) is a longitudinal cross-sectional view of the state in (d), (f) is a view of the state in (d) from the front end, and (g) is a view of the state in (d) from the rear end.

[0012] The shaft 10 has a stepped, tapered tip, with a coating body mounting section 10a at the tip for attaching the coating body 12, and a tapered section 10b behind it, which houses a cylindrical storage section 13. The coating body mounting section 10a is rectangular in shape for attaching the coating body 12 and has an opening that communicates with the inside of the shaft 10. Furthermore, a threaded section 10c is formed on the inner wall surface of the shaft 10 near the tapered section 10b, which is threaded with the threads 14b formed on the outer wall near the tip of the rust converter tank 14.

[0013] Figure 4 shows the coating body 12 of the rust converter coating container 2, where (a) is a perspective view from the front, (b) is a perspective view from the rear, (c) is a plan view, (d) is a side view, and (e) is a view from the rear. The coating body 12 has a rectangular parallelepiped coating portion 12a, a prismatic shaft portion 12b extending to the rear of the coating portion 12a, and two locking portions 12c protruding in a direction perpendicular to the axial direction of the shaft portion 12b.

[0014] The coating body 12 and the storage section 13 are formed from a porous body, which consists of, for example, a parallel fiber bundle made of one or more types of materials such as natural fibers, animal hair fibers, polyacetal resins, polyethylene resins, acrylic resins, polyester resins, polyamide resins, polyurethane resins, polyolefin resins, polyvinyl resins, polycarbonate resins, polyether resins, and polyphenylene resins; a fiber core made by processing fiber bundles such as felt or resin processing these fiber bundles; or a porous body (sintered body) made by sintering various plastic powders.

[0015] Here, the pore diameter of the porous body of the storage part 13 is larger than that of the coating body 12, and the porosity of the porous body of the storage part 13 is larger than that of the coating body 12.

[0016] FIG. 5 is a view of the rust converter tank 14 of the rust converter coating container 2, where (a) is a side view and (b) is a longitudinal sectional view. The rust converter tank 14 has a rust converter chamber (rust converter storage chamber) 14a for storing the rust converter inside, and a valve 15 is provided at the tip. By opening and closing the valve 15, the amount of the rust converter supplied to the coating body 12 is adjusted. Further, when the rust converter tank 14 is stored before use, a cap 14b for protecting the valve 15 is attached to the tip.

[0017] The rust converter stored in the rust converter chamber 14a is liquid at -5 to 40°C and has the function of converting red rust to black rust. The viscosity at 20°C is preferably 0.02 to 0.05 Pa·s. The viscosity can be measured, for example, using a rotational viscometer (Cleveland viscometer).

[0018] FIG. 6 is a view of the valve 15 of the rust converter coating container 2, where (a) is a perspective view seen from the front side, (b) is a perspective view seen from the rear side, (c) is a side view, (d) is a longitudinal sectional view, (e) is a view seen from the front side, and (f) is a view seen from the rear side.

[0019] The valve 15 has a rearward-tapering cylindrical holding frame 24, and a valve seat member 26 is fitted into the open end on the front side of the holding frame 24. A flow hole 24a for flowing the rust converter from the rust converter chamber 14a side of the rust converter tank 14 to the inside of the holding frame 24 is formed in the holding frame 24.

[0020] A valve hole 26a in which a valve body 28 is inserted so as to be able to move back and forth is formed at the center of the valve seat member 26. The surface of the valve body 28 facing the valve hole 26a is formed as a frontward-tapering tapered slope. When the slope of the valve body 28 hits the edge of the valve hole 26a, the supply path is closed, and when the slope of the valve body 28 moves away from the edge of the valve hole 26a, the supply path is opened.

[0021] The valve body 28 has a long support rod 28a at one end that extends toward the rust converter chamber 14a. The other end of the valve body 28 has a cylindrical portion 28b that protrudes toward the coating body 12. The cylindrical portion 28b is loosely fitted with a gap in the valve hole 26a of the valve seat member 26 and is positioned to protrude into the storage portion 13.

[0022] The support rod 28a is inserted into the rear hole 24b of the retaining frame 24, which extends to the rear, so as to be able to move back and forth. A biasing member spring 32 is loosely fitted between the retaining frame 24 and the support rod 28a, biasing the valve body 28 toward the front of the retaining frame 24. Normally, the valve 15 is held in a closed state by the valve body 28.

[0023] Next, the use of the rust converter application container according to this embodiment will be described. First, the rust converter tank 14 is attached to the shaft 10 of the rust converter application container 2. That is, the cap 14b of the rust converter tank 14 is removed, the rust converter tank 14 is inserted through the opening at the rear end of the shaft 10, and the rust converter tank 14 is attached to the shaft 10 by screwing the threads 14b formed on the outer wall near the tip of the rust converter tank 14 onto the threaded portion 10c formed on the inner wall of the shaft 10.

[0024] When the rust converter application container 2 is not in use, a cap 16 is placed over the tip of the application body 12 and the shaft cylinder 10 to prevent the rust converter from volatilizing, and the valve 15 is closed. As a result, the rust converter is not supplied from the rust converter chamber 14a to the application body 12, so the rust converter does not overflow into the cap 16 through the application body 12.

[0025] Figure 7 is a longitudinal cross-sectional view showing the state of the rust converter tank 14 before the valve 15 is pressed by the coating body 12 according to the embodiment, and Figure 8 is a longitudinal cross-sectional view showing the state of the rust converter tank 14 after the valve 15 has been pressed by the coating body 12. When using the rust converter coating container 2, remove the cap 16 and push in the coating body 12. When the coating body 12 is pushed in, the rear end of the shaft portion 12b of the coating body 12 presses against the cylindrical portion 28b of the valve body 28, pushing the valve body 28 against the biasing force of the spring 32 of the valve 15. As a result the valve body 28 separates from the valve seat member 26, opening the valve hole 26a and opening the valve 15, so that the rust converter is supplied from the rust converter chamber 14a to the storage portion 13.

[0026] By repeatedly pushing in the coating body 12, a large amount of rust converter can be supplied to the reservoir 13. By repeating this pushing operation, the valve 15, which has a valve seat member 26, a valve body 28, and a retaining frame 24, performs a pumping action. Here, the pore diameter of the porous material of the reservoir 13 is larger than the pore diameter of the coating body 12, and the porosity of the porous material of the reservoir 13 is greater than the porosity of the coating body 12. That is, the capillary force of the coating body 12 is stronger than the capillary force of the reservoir 13, so the rust converter stored in the reservoir 13 is supplied to the coating body 12, and air enters the reservoir 13 in place of the supplied rust converter. Therefore, the rust converter can be applied by the coating body 12 without streaking.

[0027] Figure 9 illustrates the replacement of the coating body and rust converter tank of a rust converter application container according to an embodiment. When replacing the coating body 12, the coating body 12 is pulled out axially, and the new coating body 12 is pushed into the coating body mounting section 10a. Since the coating body 12 has a locking portion 12c, it is prevented from coming off the coating body mounting section 10a even when pressure is applied to the coating body 12. When replacing the rust converter tank 14, the rust converter tank 14 is pulled out from the rear end of the shaft cylinder 10, the new rust converter tank 14 is inserted through the opening at the rear end of the shaft cylinder 10, and the rust converter tank 14 is attached to the shaft cylinder 10 by screwing the threads 14b formed on the outer wall of the rust converter tank 14 into the threads 10c formed on the inner wall of the shaft cylinder 10.

[0028] According to this embodiment, the rust converter application container 2 allows for the application of the rust converter without the need to separately prepare a container for the rust converter or a brush for application, and also allows for the application of the rust converter without streaking. Furthermore, because the rust converter application container 2 has a cap, there is no need to clean the application part 12 after use. [Industrial applicability]

[0029] The rust converter application container of the present invention can be used as an application container for rust converters and other functional agents. [Explanation of Symbols]
