[Prior art]

 FIG. 9 shows a conventional liquid applicator partially broken away. In this liquid medicine applicator, a cylindrical liquid medicine storage container 31 also serving as a hand-held grip, and an inner lid 33 attached to a cylindrical opening 32 formed at one longitudinal end of the liquid medicine storage container 31. And an application body 34 held by the inner lid 33.

The inner lid 33 is provided with a cylindrical portion 41 and an insertion portion 42 concentrically. The insertion portion 42 is pressed into the inside of the cylindrical mouth portion 32, and is provided on the inner periphery of the distal end portion of the cylindrical portion 41. The inner lid 33 is attached to the tubular mouth 32 by engaging the ring-shaped engaging portion 43 with an engaged portion 44 provided on the outer periphery of the tubular mouth 32. Thereby, the contact portion between the insertion portion 42 and the cylindrical mouth portion 32 is sealed in a liquid-tight manner.

A liquid outlet 45 is formed at a center position of the insertion section 42 in the inner lid 33, and a liquid amount adjusting member 35 is mounted in the insertion section 42. An adjustment hole 35a is formed in the liquid amount adjustment member 35, and the liquid agent in the liquid agent storage container 31 flows out of the outlet 45 of the insertion portion 42 through the adjustment hole 35a, thereby suppressing the amount of the liquid agent flowing out. . The liquid agent flowing out of the outlet 45 infiltrates the application body 34 or is applied to the surface to be applied.

[Problems to be solved by the invention]

 According to the liquid medicine applicator having the above-described configuration, the function of the liquid amount adjusting member 35 as a baffle plate does not easily cause a large amount of liquid medicine in the liquid medicine storage container 31 to flow out directly from the outlet 45. However, since the path from the adjusting hole 35a of the liquid amount adjusting member 35 to the outlet 45 of the liquid agent of the inner lid 33 is short and monotonous, when the liquid agent is applied with the cylindrical mouth portion 32 facing downward. It has been difficult to prevent a situation in which more than necessary liquid material flows out of the outlet 45 of the inner lid 33 at one time.

In addition, a situation in which the liquid agent that has exited from the outlet 45 travels along the outer surface 33 a of the inner lid 33 around the outlet, and many liquid agents remain adhered to a wide area of the outer surface 33 a of the inner lid 33. Was found to occur.

The present invention has been made in view of the above circumstances, and provides a liquid applicator capable of minimizing a flow of a required amount of liquid from a liquid storage container at a time when applying the liquid. The purpose is to do. In addition, in the present invention, by devising the shape around the outlet of the liquid agent, the liquid at the outlet of the liquid agent is desirably drained after use, and the liquid discharged from the outlet during use becomes around the outlet after use. It is an object of the present invention to provide a liquid medicine applicator that is unlikely to remain attached to a wide area of the liquid medicine.

[0009]

[Means for Solving the Problems]

 In the liquid medicine applicator according to the present invention, a nozzle having a liquid medicine outlet is attached to the cylindrical mouth of the liquid medicine storage container, and the liquid medicine coming out of the liquid medicine outlet is applied around the nozzle to the surface to be coated. Is applied. For this reason, when the liquid agent is caused to flow out of the liquid agent outlet of the nozzle with the liquid agent storage container facing downward, it is possible to apply the discharged liquid agent to the surface to be coated with the application body.

In the present invention, the nozzle is formed on an outer peripheral surface of a nozzle body fitted to the cylindrical mouth, and forms a liquid agent outflow passage in cooperation with an inner peripheral surface of the cylindrical mouth. It has a spiral groove and the liquid agent outlet which communicates with a communication passage that opens to a part of the spiral groove. For this reason, the liquid material flow path until the liquid material in the liquid material storage container reaches the liquid material outlet of the nozzle is formed by a spiral liquid material outflow path, so that the liquid material flow path to the liquid material outlet is not monotonous, In addition, since the length of the flow path is increased, an unnecessarily large amount of liquid material is prevented from flowing out of the liquid material outlet at one time when the liquid material is applied.

In the present invention, the liquid agent outlet is opened at an end surface of a small-diameter projection formed concentrically inside a cylindrical portion provided at one end of the nozzle body, and A recessed annular liquid cutting groove is provided between the small-diameter projection and the cylindrical portion. According to this, the liquid drainage property of the liquid discharged from the liquid outlet is improved. In other words, in the state of use in which the liquid agent storage container is facing downward, when the liquid agent coming out of the liquid agent outlet tries to flow outside the end face of the small-diameter projection, the annular liquid cut groove prevents the liquid agent from flowing out. This function is effective, and the liquid does not spread to the outside of the end face of the small diameter protrusion. For this reason, a situation in which the liquid material discharged from the liquid material outlet during use remains attached to a wide area around the liquid material outlet after use does not occur.

In the liquid medicine applicator of the present invention, it is preferable that the cylindrical portion protrudes in the axial direction from the small-diameter cylindrical portion. In this case, when the liquid medicine storage container is turned upright after use, and the liquid medicine discharged from the liquid medicine outlet is accumulated in the annular liquid cut groove, the liquid medicine flows to the outside of the cylindrical portion. It cannot happen that it spills and wets the surroundings.

In the liquid medicine applicator of the present invention, the application body may be held by a holding table provided concentrically with the cylindrical mouth around the cylindrical mouth. In this case, the application body can be stably held in a state surrounding the cylindrical mouth.

In the liquid medicine applicator of the present invention, a screw portion to which a cap for covering the application body is screwed may be provided on the outer peripheral surface of the cylindrical mouth portion. In this case, the cap can be easily and securely attached to the cylindrical mouth of the liquid agent storage container.
