The O-ring 23 can block the communication between the storage space X and the outside through the gap between the inner shaft 22 and the outer shaft 12 regardless of the advancement and retreat of the inner shaft 22, and suppress the liquid leakage to the outside. can.

As shown in FIGS. 2 to 3, four vertical grooves 24 are provided on the outer peripheral surface of the inner shaft extension portion 22b so as to be arranged at intervals in the circumferential direction and extend over the shaft length excluding the upper portion. Has been done. Each of the four vertical grooves 24 receives the vertical rib 16 of the outer shaft extension portion 12b. Further, at the lower portion of the outer peripheral surface of the inner shaft extension portion 22b, four locking convex portions 25 are provided at predetermined height positions at intervals in the circumferential direction and projecting outward in the radial direction. Each of the four locking protrusions 25 has a bottom view arc shape extending in the circumferential direction between two vertical grooves 24 adjacent to each other. At the initial position, each of the four locking convex portions 25 is normally locked to the locking convex portion 17 of the outer shaft extension portion 12b so that the retreat of the inner shaft 22 can be regulated.

The upper portion of the inner shaft extension portion 22b is fitted with the operating member 9. The operation member 9 has a disk-shaped top wall 26 centered on the central axis O. On the lower surface of the top wall 26, a cylindrical insertion cylinder 27 that is inserted into the inner shaft extension portion 22b and is in contact with the inner peripheral surface of the inner shaft extension portion 22b is vertically installed. The upper end of the cylindrical upper peripheral wall 28 is integrally connected to the outer peripheral edge of the top wall 26. The outer peripheral surface of the upper portion of the inner shaft extension portion 22b is fitted to the inner peripheral surface of the upper peripheral wall 28. At the lower end of the upper peripheral wall 28, the upper end of the cylindrical lower peripheral wall 29 having an inner diameter expanded from the upper peripheral wall 28 and an outer diameter corresponding to the upper peripheral wall 28 is integrally connected.

As shown in FIGS. 2 to 3, at the lower end of the lower peripheral wall 29, four legs 31 extending in the axial direction of the outer shaft 12 through the opening 30 provided in the inward flange 6b hang down. It is set up. The four legs 31 are arranged at intervals on the circumference centered on the central axis O, which is smaller than the outer diameter of the mouth portion 2a and larger than the inner diameter of the mouth portion 2a. Therefore, the lower end surfaces of the four legs 31 can come into contact with the upper end surfaces of the mouth portion 2a. Further, the inward flange 6b is provided with four openings 30 having the same number as the number of legs 31. The four legs 31 and the four openings 30 each have a bottom view arc shape. Each of the four legs 31 is guided by the opening 30 so as to be able to move up and down. Further, the four protrusions 15b of the outer shaft 12 described above are arranged between the two legs 31 adjacent to each other. Therefore, the cap member 6, the operation member 9, and the outer shaft member 7 are restricted from rotating relative to each other around the central axis O. Further, the outer shaft member 7 and the inner shaft member 8 are restricted from rotating relative to each other around the central axis O by the engagement between the vertical rib 16 and the vertical groove 24.

The container body 4 is formed by blow molding of a synthetic resin. The handling inner plug 5, the cap member 6, the outer shaft member 7, the inner shaft member 8, the operating member 9, and the closing member 18 are formed by injection molding of synthetic resin. The O-ring 23 is formed by injection molding of rubber or elastomer. However, these materials and manufacturing methods can be changed as appropriate.

As shown in FIG. 2, when the applicator 3 is attached to the mouth portion 2a, the applicator body 14 is located in the accommodation space S. At this time, the coating body 14 is immersed in the content liquid C. Further, the content liquid C has infiltrated into the storage space X.

Next, the user can pick up the cylinder wall 6a of the cap member 6 and remove the applicator 3 from the mouth portion 2a as shown in FIG. At that time, since the content liquid C adhering to the coating body 14 is appropriately scraped off by the handling cylinder 5c, it is possible to suppress the dripping of the content liquid C. Then, the user can apply the content liquid C adhering to the coating body 14 to the desired portion to be coated with the cylinder wall 6a pinched.

When the amount of the content liquid C adhering to the coating body 14 decreases, the user pushes the top wall 26 of the operating member 9 to advance the inner shaft 22 and causes the inner shaft 22 to move forward, as shown in FIG. The content liquid C in the storage space X can be extruded from the storage space X and adhered to the coating body 14. Then, the user can further apply the content liquid C extruded from the storage space X by the coating body 14. In this way, the top wall 26 can function as an operation unit 32 that receives a pressing operation for advancing the inner shaft 22. The operation unit 32 is connected to the inner shaft 22 so as to be able to advance and retreat together with the inner shaft 22 by fitting the inner shaft member 8 and the operation member 9 described above. According to the present embodiment, a wide range of coating is possible by a simple operation of pressing the operation unit 32.

Further, when the inner shaft 22 advances by operating the operation unit 32, the tip portion of the inner shaft 22 has a tapered shape, so that the content liquid C in the storage space X is moved to the outside in the circumferential direction of the storage space X. It can be smoothly extruded at the tip of the inner shaft 22 into the plurality of through holes 13 located in.

When the application of the content liquid C is completed or further application is performed, the user inserts the outer shaft 12 into the accommodation space S and attaches the coating tool 3 to the mouth portion 2a as shown in FIG. Can be done. At that time, the tip portions (lower end portions) of the four leg portions 31 come into contact with the tip end surface (upper end surface) of the mouth portion 2a as the outer shaft 12 is inserted into the accommodation space S, so that the inner shaft 22 is pressed. It can function as a contact portion 33 to be retracted. The contact portion 33 is connected to the inner shaft 22 so as to be able to advance and retreat together with the inner shaft 22 by fitting the inner shaft member 8 and the operating member 9 described above. According to the present embodiment, the inner shaft 22 is retracted and the content liquid is contained in the storage space X as shown in FIG. 2 without performing a special operation other than the operation for attaching the coating tool 3 to the mouth portion 2a. C can be drawn in and prepared for the next widespread application.

It goes without saying that the above-described embodiment is merely an example of the embodiment of the present invention and can be variously modified without departing from the gist of the invention.

In the above embodiment, the applicator 3 includes four legs 31, but the number of legs 31 can be increased or decreased as appropriate. It is also possible to change the configuration so that the legs 31 are not provided.

In the above embodiment, the mouth portion 2a of the container 2 has a cylindrical shape, but the shape of the mouth portion 2a is not limited to the cylindrical shape, and may be a cylindrical shape other than the cylindrical shape such as a square tubular shape. In the above embodiment, the body portion 4b has a bottomed cylindrical shape, but the shape of the body portion 4b can be changed as appropriate.
