Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a liquid applicator for applying a liquid such as a flux liquid or an adhesive.

[0002]

[Prior art]

 In general, when mounting electronic parts, flux liquid is applied to the lead wires and wiring pattern parts of electronic parts to improve solderability. Conventionally, flux liquid is applied as a practical application. The liquid applicator of Sho 63-130131 is known (proposed by the applicant).

In the liquid applicator, as shown in FIG. 6, a container lid 5 provided with a tubular body 6 is detachably screwed to an opening 3 of a container body 1 for containing a liquid 2 such as a flux liquid. Then, the coating member 8 having the needle-shaped nozzle 9 at the axis is attached to the cylindrical body 6 of the container lid 5.

When applying the liquid 2 such as the flux liquid, the liquid 2 such as the flux liquid coming out through the applying member 8 is applied with the container lid 5 to which the applying member 8 is attached facing down. .

[0005]

[Problems to be solved by the device]

 However, in the above liquid applicator, the permeability of the liquid 2 through the coating member 8 varies depending on the viscosity of the liquid 2, and therefore, in the case of the liquid 2 having low viscosity, there is a possibility that the liquid 2 will be overfilled.

Further, if the liquid applicator is laid sideways, that is, if the liquid 2 is left in a state where it is forgotten and left as it is, the liquid 2 may leak through the application member 8 and leak. It was

The present invention has been made in view of the above, and an object of the present invention is to prevent a liquid from excessively flowing out by making a desired amount of liquid come out, and even when the liquid is left in a discharged state, The aim is to provide a leak-free liquid applicator.

[0008]

[Means for Solving the Problems]

 The present invention relates to a liquid applicator in which a container lid provided with a tubular body is detachably attached to an opening of a container body for containing a liquid, and a coating member is attached to the tubular body of the container lid. It is characterized in that an inner lid having a valve in which radial cuts are formed is interposed between the container body and the container lid.

[0009]

[Action]

 When applying the liquid, press the outer surface of the container main body with your container lid with the coating member down and press the outer surface of the container main body with your finger or the like to open the valve of the inner lid by the internal pressure, and the liquid inside the container main body will apply the coating member. Moved to the cylinder side. At the same time as the pressing of the outer surface of the container body is stopped, the valve of the inner lid is closed and the movement of the liquid is stopped.

Therefore, the liquid transferred to the side of the cylinder to which the coating member is attached penetrates into the coating member, and a desired amount of liquid is discharged to the outside. Further, even if the liquid applicator is laid on its side and left in a state where the liquid comes out, the valve of the inner lid is not opened unless the container main body is pressed, so that the liquid does not leak.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 shows an embodiment of a liquid applicator according to the present invention.

In FIG. 1, reference numeral 1 denotes a container main body, and a liquid 2 to be applied, for example, a flux liquid is stored in the container main body 1. The container body 1 is made of a synthetic resin material, such as polyvinyl chloride, which is insoluble in the liquid 2 contained therein, and an external screw 4 is formed in the opening 3 of the container body 1.

On the other hand, 5 is a container lid made of the same synthetic resin as the container body 1, for example, polyvinyl chloride, and a cylindrical tubular body 6 is integrally provided on the upper part thereof, and the inner surface of the container lid 5 is Internal screws 7 are formed on the side.

A coating member 8 capable of penetrating the liquid 2 is attached to the tip of the cylindrical body 6 of the container lid 5, for example, a bristle member in which hairs are bundled. A needle-shaped nozzle 9 for guiding the liquid 2 to the tip of the coating member 8 is provided at the axis of the bristle member (coating member) 8.

Reference numeral 10 denotes a cap-shaped inner lid which is formed between the container body 1 and the container lid 5 and is made of an elastic material such as polyethylene. As shown, a valve 11 is provided that is radially cut, for example, in a cross shape.

A container lid 5 to which a coating member 8 is attached via an inner lid 10 having a valve 11 is detachably screwed to the opening 3 of the container body 1. Further, a liquid body applicator having a structure in which a cap 12 for preventing the solvent of the liquid (flux liquid) 2 from drying and the adhesion of dust is detachably attached to the cylindrical body 6 to which the coating member 8 is attached. ing.

When a liquid 2 such as a flux liquid or an adhesive is applied using such a liquid applicator, the application member 8 is placed on the lower side to be a surface to be coated, such as a lead wire of an electronic component or a wiring pattern. The application member 8 is brought into contact with the portion to apply the liquid 2.

At this time, when the outer surface of the container body 1 is pressed with a finger or the like, the valve 11 of the inner lid 10 is opened by the internal pressure, and the liquid 2 in the container body 1 of the container lid 5 to which the coating member 8 is attached. The liquid 2 transferred to the cylinder 6 side permeates the coating member 8 or the coating member 8 directly through the needle-like nozzle 9 having the axial center, and goes out through the coating member 8 to the outside to be the electronic component to be coated. Applied to the lead wire and wiring pattern part of the.

The liquid 2 moving from the container body 1 to the cylinder body 6 side through the valve 11 of the inner lid 10 is stopped by closing the valve 11 at the same time when the pressing of the container body 1 by the finger is stopped. Therefore, the amount of the moving liquid of the liquid 2 to the side of the cylinder body 6 having the coating member 8 is determined by the magnitude of pressing of the container body 1 and the pressing time. Therefore, a desired amount of the liquid 2 that is appropriate and necessary in consideration of the viscosity of the liquid 2 is held and secured on the side of the tubular body 6 having the coating member 8, and then the desired amount of the liquid 2 is transferred to the outside. It is possible to prevent the liquid 2 from excessively flowing out.

Further, even if the liquid applicator is laid sideways, that is, even if the liquid 2 is left in a discharged state and is forgotten to be left, the valve 11 of the inner lid 10 is not opened unless the container body 1 is pressed. 2 leaks go away.

The valve 11 of the inner lid 10 is formed by cutting the upper surface of the inner lid 10 in a cross shape. However, as shown in FIG. 3, it is formed by cutting in a water shape or other radial shape. Alternatively, as shown in FIG. 4, the inner lid 10 may be of a disc shape, and a cut may be formed in the center thereof, for example, in the shape of a cross to have a valve 11. .

Further, the coating member 8 attached to the cylindrical tubular body 6 of the container lid 5 does not have the needle-shaped nozzle 9 at the axial center of the bristle member (coating member) 8, and as shown in FIG. The hairless hollow portion 13 from which the axial center portion of the member (application member) 8 is removed may be formed, and the liquid 2 may be guided to the tip through the hairless hollow portion 13.

Further, the coating member 8 is not limited to a bristling member in which bristles are bundled, and other material having fine porosity that allows liquid to move by a capillary phenomenon can be used.

[0024]

[Effect of device]

 According to the present invention described above, a desired amount of liquid comes out of the application member by pressure adjustment regardless of the viscosity of the liquid, and it is possible to prevent the liquid from coming out too much.

Further, even if the liquid is left in a discharged state, there is a remarkable effect that the liquid does not leak unless the container body is pressed.
