The inner diameter of the inner peripheral wall 45a is large enough to allow the application member 70 to be inserted therein. The application member 70 is, for example, a cotton swab 73 having a cotton portion 72 provided at the tip of a stick portion 71 . When the application member 70 is a cotton swab 73, the inner diameter of the inner peripheral wall 45a is, for example, approximately the same diameter as the outer diameter of the largest diameter portion of the cotton portion 72 of the cotton swab 73. The radial depth of the discharge port 45 can be set to about half the length of the cotton portion 72 of the cotton swab 73 . As a result, as shown in FIG. 4, about half of the front end side of the cotton portion 72 provided at the front end of the stick portion 71 of the cotton swab 73 can be inserted into the second ejection port 45 without any gap. Then, with the cotton portion 72 of the cotton swab 73 inserted into the second discharge port 45 without any gap, the discharge head 60 is pushed down to supply the content liquid L from the pump 30 to the second discharge port 45 . Thus, the content liquid L can be adhered to the cotton portion 72 of the cotton swab 73 inside the second ejection port 45 without scattering the content liquid L to the outside.

In addition, a plurality of groove-shaped liquid flow paths 45c extending from the second flow path 49 side toward the outer peripheral surface side of the peripheral wall portion 43 are arranged side by side in the circumferential direction on the inner surface of the second discharge port 45 at intervals. As a result, the content liquid L supplied from the second flow path 49 to the inside of the second discharge port 45 can be spread over the entire cotton portion 72 of the cotton swab 73 through the plurality of liquid flow paths 45c. can.

Furthermore, since the radially outer end of each liquid flow path 45c is arranged closer to the second flow path 49 than the outer peripheral surface of the peripheral wall portion 43, the content liquid flowing through the plurality of liquid flow paths 45c It is possible to suppress the flow of L to the outside of the second outlet 45 as it is.

The inside diameter of the inner peripheral wall 45a of the second discharge port 45 is such that the content liquid L does not blow out from between the inner peripheral surface of the inner peripheral wall 45a and the outer peripheral surface of the cotton portion 72 of the cotton swab 73. may be larger than the outer diameter of the largest diameter portion of the cotton portion 72 of the cotton swab 73, and if the cotton portion 72 of the cotton swab 73 can be inserted, the outer diameter of the largest diameter portion of the cotton portion 72 of the cotton swab 73 may be smaller than

Further, the radial depth of the second discharge port 45 is preferably a depth that can accommodate about half of the tip side of the cotton portion 72 of the cotton swab 73, but the entire cotton portion 72 of the cotton swab 73 can be accommodated. Various changes are possible as long as the depth allows the cotton portion 72 of the cotton swab 73 to be inserted.

The cover member 50 constitutes an ejection head 60 together with the head member 40, and has two ejection modes, one for ejecting the content liquid L in the form of a mist from the first ejection port 44, and the other for ejecting the content liquid L from the second ejection port 45 in the form of an application member 70 (a cotton swab). 73) to adhere to the cotton portion 72).

The cover member 50 has a topped cylindrical shape having a top wall 51 and a cover peripheral wall 52 that covers the peripheral wall portion 43 . The cover member 50 is attached to the head member 40 so as to be relatively rotatable about the axis O of the cylindrical portion 41 by fitting the cover peripheral wall 52 to the outer peripheral surface of the peripheral wall portion 43 so as to be slidable in the circumferential direction. there is

When the cover member 50 is in the first rotation position (the position shown in FIGS. 1 and 3), the cover peripheral wall 52 opens the first discharge port 44 to the outside, and the cover member 50 rotates to the first rotation position. An open hole 52a is provided for opening the second discharge port 45 to the outside when it is in the second rotational position (position shown in FIG. 4) shifted by 180 degrees from the front. The open hole 52a is a circular hole having a diameter larger than that of the first outlet 44 and the second outlet 45, and the content liquid is sprayed in the form of a mist from the first outlet 44 when it is in the first rotation position. In addition, the cotton portion 72 of the cotton swab 73 can be inserted into the second ejection port 45 without obstruction when it is in the second rotation position.

The top wall 51 is inclined with respect to the cover peripheral wall 52 so that the side on which the open hole 52a is provided is higher. As a result, the user recognizes that the top wall 51 has the open hole 52a on the side where the top wall 51 is higher, and the liquid ejector 1 is sprayed from the first ejection port 44 in the direction of inclination of the top wall 51. It is possible to easily recognize which mode of the mode in which the liquid is ejected to the second outlet 45 and the mode in which the liquid is adhered to the coating member 70 from the second outlet 45 .

The lower surface of the top wall 51 of the cover member 50 is integrally provided with a cylindrical closing portion 53 centered on the axis O, and this closing portion 53 is rotatably fitted into the upper end opening of the head member 40. By doing so, the upper end of the main flow path 42 is closed.

The partition wall 54 has a size capable of blocking the first flow path 47 and the second flow path 49 respectively, and the lower end of the partition wall 54 is fitted into the diameter-reduced tubular portion forming the main flow path 42 of the head member 40 . there is

As shown in FIG. 3, the partition wall 54 is arranged between the main channel 42 and the second channel 49 when the cover member 50 is in the first rotational position. Thereby, when the cover member 50 is in the first rotation position, the communication between the main flow path 42 and the second flow path 49 (second discharge port 45 ) is blocked by the partition wall 54 . At this time, a gap 55 in which no partition wall 54 is provided is arranged between the main flow path 42 and the first flow path 47 . Therefore, when the discharge head 60 is pushed down and the content liquid L is supplied from the pump 30 to the main flow path 42 when the cover member 50 is in the first rotation position, the content liquid L is blocked by the partition wall 54 . It is not supplied to the second flow path 49 or the second ejection port 45, but is supplied to the first flow path 47, that is, the first ejection port 44 through the gap 55. As shown in FIG. As a result, the content liquid L is discharged outside in the form of a mist from the first discharge port 44 .

On the other hand, as shown in FIG. 4, the partition wall 54 is arranged between the main flow path 42 and the first flow path 47 when the cover member 50 is in the second rotational position shifted in the rotational direction from the first rotational position. be. Thereby, when the cover member 50 is in the second rotation position, the communication between the main flow path 42 and the first flow path 47 (the first discharge port 44) is blocked by the partition wall 54 . At this time, a gap 55 in which no partition wall 54 is provided is arranged between the main flow path 42 and the second flow path 49 . Therefore, when the discharge head 60 is pushed down and the content liquid L is supplied from the pump 30 to the main flow path 42 when the cover member 50 is in the second rotation position, the content liquid L is blocked by the partition wall 54 . It is not supplied to the first flow path 47 or the first discharge port 44, but is supplied to the second flow path 49, that is, the second discharge port 45 through the gap 55. As shown in FIG. As a result, the content liquid L is supplied to the second ejection port 45 so as to adhere to the application member 70 (the cotton portion 72 of the cotton swab 73) inserted into the second ejection port 45.
