[0008] <Aerosol spray can> The aerosol spray can 1 according to this embodiment is used for repairing metal siding materials. The metal siding materials are used, for example, as exterior materials for the exterior walls of buildings. As shown in FIG. 1, the aerosol spray can 1 has a gas container 20 in which a propellant is stored, a liquid container 30 in which a coating composition for repairing metal siding materials is stored, and a connecting member 10 that connects the gas container 20 and the liquid container 30.

[0009] (Gas container) The gas container 20 has a cylinder 21 made of, for example, a metal, filled with a propellant, and a holder 22 attached to the cylinder 21 .

[0010] The propellant stored in the cylinder 21 is not particularly limited, and various known propellants used in aerosol products can be used. For example, liquefied gas, compressed gas, etc. can be used as the propellant. Examples of the liquefied gas include various liquefied petroleum gases, dimethyl ether, and liquefied gases obtained by mixing these. Examples of the compressed gas include compressed gases such as nitrogen gas and carbon dioxide gas. The propellant stored in the cylinder 21 can be ejected to the outside of the cylinder 21 by depressing a stem (not shown) provided at the top of the cylinder 21.

[0011] The holder 22 has a push button 221 and a head portion 222. The holder 22 is integrally molded from, for example, a synthetic resin etc. The holder 22 is attached to the upper portion of the cylinder 21 by, for example, a fitting method.

[0012] Push button 221 is attached to a stem provided at the top of cylinder 21. Inside push button 221, a flow path is provided that communicates with the stem and nozzle 223 described below. By pressing push button 221, the stem is pressed down. As a result, the propellant stored in cylinder 21 is sprayed from nozzle 223 via the flow path provided inside push button 221.

[0013] 1 and 2, the head portion 222 has an injection port 223 and a nozzle 224. As shown in Fig. 3, the head portion 222 has a circular opening that opens downward and into which a part of the connection member 10 can be inserted. A female screw portion 226 is formed on the inner circumferential surface of the opening as a first screw portion that can be screwed into the connection member 10. The opening communicates with the nozzle 224 as shown in Fig. 3.

[0014] From the nozzle 223, the propellant stored in the cylinder 21 is sprayed in the direction shown by the arrow in Fig. 3. From the nozzle 224, the coating composition stored in the liquid container 30 is discharged. As shown in Figs. 2 and 3, a tube 225 is connected to the nozzle 224. The tube 225 is a cylindrical member having a flow path therein through which the coating composition can flow. The coating composition is supplied to the nozzle 224 through the tube 225. The tip of the tube 225 is inserted into the coating composition stored in the liquid container 30. The tube 225 may be detachable from the nozzle 224.

[0015] (liquid container) The liquid container 30 is a container for storing a paint composition for repairing metal siding. The paint composition is not particularly limited, and for example, an existing paint composition containing a pigment, a resin, a solvent, etc. can be selected and used according to the color of the metal siding material to be repaired. The paint composition can be appropriately adjusted to a viscosity suitable for spray application.

[0016] The liquid container 30 is configured to be detachable from the gas container 20 via the connecting member 10. An existing container used for storing the coating composition can be repurposed as the liquid container 30. The liquid container 30 has, for example, a cylindrical container body, and as shown in Figs. 2 and 3, a male screw portion 31 is formed on the top of the container body. After the coating composition is filled inside the liquid container 30, a female screw portion (not shown) formed inside the lid portion C is screwed into the male screw portion 31. This causes the coating composition to be sealed inside the liquid container 30. The male screw portion 31 is used as a third screw portion for connection to the connecting member 10.

[0017] (Connection parts) The connecting member 10 is a member that connects the gas container 20 and the liquid container 30. The connecting member 10 has a substantially cylindrical shape, as shown in Figures 2 and 3. The cylindrical shape may have different diameters at both ends depending on the diameters of the gas container 20 and the liquid container 30. The connecting member 10 has a space therein through which the tube 225 can be inserted, as shown in Figures 2 and 3.

[0018] A male screw portion 11 is formed as a second screw portion on the outer peripheral surface of one end of the connection member 10. The male screw portion 11 can be screwed into a female screw portion 226 formed on the inner surface of the head portion 222 of the gas container 20. A female screw portion 12 is formed as a fourth screw portion on the inner peripheral surface of the other end of the connection member 10. The female screw portion 12 can be screwed into a male screw portion 31 formed on the top of the liquid container 30. This allows the connection member 10 to connect the liquid container 30 using the male screw portion 31 used to screw into the lid portion C of the liquid container 30. For this reason, for example, the work of transferring the coating composition to a dedicated container is not required, and the workability during application can be improved.

[0019] The connection member 10 is integrally molded from, for example, synthetic resin. Therefore, the diameter of the inner peripheral surface on which the female thread portion 12 is formed can be adjusted according to the diameter of the male thread portion formed on the top of the liquid container 30. This allows the connection member 10 to be connected to a plurality of liquid containers 30 having different diameters. For example, by preparing a plurality of connection members 10 having different diameters of the inner peripheral surface according to the diameter of an existing liquid container 30, a plurality of liquid containers 30 having different diameters can be connected to the gas container 20.

[0020] A procedure for connecting the gas container 20 and the liquid container 30 using the connection member 10 will be described with reference to FIG. 2. First, a procedure for connecting the gas container 20 and the connection member 10 will be described. A tube 225 is connected to the nozzle 224 of the gas container 20. Next, the tube 225 is inserted into the inside of the connection member 10 from one end side of the connection member 10. Next, one end side of the connection member 10 is inserted into the opening of the head part 222. Next, the male thread part 11 of the connection member 10 and the female thread part 226 formed on the inner surface of the opening are screwed together and fixed. In this state, the tube 225 protrudes from the other end side of the connection member 10.

[0021] Next, the procedure for connecting the liquid container 30 to the gas container 20 to which the connecting member 10 is connected will be described. First, the lid C of the liquid container 30 is removed. Next, the tube 225 is inserted into the liquid container 30 so that the tip of the tube 225 is submerged in the coating composition stored in the liquid container 30. Next, the female screw portion 12 of the connecting member 10 and the male screw portion 31 of the liquid container 30 are screwed together and fixed. Through the above procedure, the gas container 20 and the liquid container 30 are connected by the connecting member 10 as shown in FIG. 3. In this way, by connecting the gas container 20 and the liquid container 30 by screwing using the connecting member 10, the gas container 20 and the liquid container 30 can be reliably connected. Therefore, even if the weight of the liquid container 30 is heavy or the viscosity of the coating composition is low, it is possible to prevent the liquid container 30 from coming off or the coating composition from leaking.

[0022] <Metal siding repair method> The method for repairing a metal siding material according to this embodiment includes a spray application step of spraying a paint composition onto the metal siding material to be repaired, using the above-mentioned aerosol spray can 1. This allows the paint composition to be applied uniformly to the repaired portion of the metal siding material, as compared with the conventional repair method using brush painting, so that repair marks after repair are not noticeable and a favorable finished appearance can be obtained.

[0023] A method of spray coating using the aerosol spray can 1 according to this embodiment will be described below. A user of the aerosol spray can 1 (hereinafter referred to as "user") selects a liquid container 30 in which a paint composition corresponding to the color of the metal siding material to be repaired is stored, and connects it to the gas container 20 using the connection member 10 according to the above-mentioned procedure. Next, in the spray coating process, the user aims the nozzle 223 of the aerosol spray can 1 at the repair location and presses the push button 221. As a result, the paint composition stored in the liquid container 30 is spray-coated evenly onto the repair location.

[0024] When a user presses push button 221, propellant is sprayed from nozzle 223 in the direction shown by the arrow in Fig. 3. This generates a negative pressure due to the spray airflow of the propellant. This negative pressure generates a suction force in tube 225, and the paint composition stored in liquid container 30 is sucked up through tube 225. The sucked up paint composition is discharged from nozzle 224 and sprayed in the direction of the arrow in Fig. 3 together with the propellant sprayed from nozzle 223. This allows the paint composition to be sprayed evenly onto the repaired portion of the metal siding material.

[0025] FIG. 5 is a photograph of a metal siding material repaired by a conventional repair method using brush painting. As shown in FIG. 5, in the conventional repair method using brush painting, repair marks were formed at the places where brush painting was performed, and the repair marks were clearly noticeable compared to other places. In contrast, FIG. 4 is a photograph of a metal siding material repaired by a method of spraying a paint composition using the aerosol spray can 1 according to the present embodiment. As shown in FIG. 4, the repair marks of the metal siding material repaired by the repair method using the aerosol spray can 1 according to the present embodiment were inconspicuous to the extent that they could not be distinguished from other places.

[0026] The preferred embodiments of the present disclosure have been described above. The present disclosure is not limited to the above embodiments, and modifications and improvements are included in the present disclosure.

[0027] In the above embodiment, an opening is formed in the head portion 222, and the male screw portion 11 of the connection member 10 is screwed into the female screw portion 226 formed on the inner surface of the opening. This is not limited to the above. A male screw portion may be formed in the head portion 222, and a female screw portion that can be screwed into the male screw portion may be formed in the connection member 10.
