As described above, the head portion 30 is provided with an elastic deformation portion 32c that can be elastically deformed so as to expand and contract in the direction of the axis O. Since the head portion 30 is provided with the elastic deformation portion 32c, the top wall portion 31 functions as an operating portion. That is, when the top wall portion 31 is pushed down from the state shown in FIG. 1 to the state shown in FIG. As a result, the internal space S of the head section 30 is reduced in volume and pressurized.

When the internal space S is pressurized, the first check valve 50 is opened while the second check valve 60 is kept closed, and the contents stored in the internal space S are discharged from the outlet 35. It passes through the discharge hole 41 and is discharged from the nozzle 40 to the outside. By providing the elastically deformable portion 32c in this manner, the head portion 30 functions as a pump.

After the contents have been discharged, when the top wall 31 is released from being pressed down, the top wall 31 and the elastic deformation portion 32c are deformed by the elasticity of the top wall 31 or the elastic deformation portion 32c, as shown in FIG.

Thereafter, by repeating the downward pressing operation and release of the top wall portion 31, the contents can be appropriately discharged to the outside from the discharge hole 41 of the nozzle 40.

Note that the elastically deformable portion 32c provided in the head portion 30 is not limited to the above-described bellows-shaped portion, but may be configured to elastically deform so as to reduce the volume of the head portion 30 when the top wall portion 31 is pushed downward. If so, various configurations can be adopted.

Next, details of the nozzle 40 will be explained.

As shown in FIGS. 4, 5, and 6, the nozzle 40 includes a rotating body 42 and a convex portion 43. As shown in FIGS.

The rotating body 42 has a cylindrical portion 42a. As shown in FIG. 6, the cylindrical portion 42a is fitted inside the attachment portion 36, and the annular protrusion 42b provided on the outer peripheral surface of the cylindrical portion 42a is connected to the annular groove provided on the inner peripheral surface of the attachment portion 36. 36a. Thereby, the rotating body 42 is mounted on the head portion 30 so as to be rotatable about the rotation axis RA.

As shown in FIGS. 4, 5, and 6, the discharge hole 41 is provided in a nozzle body 42c that is integrally connected to the front end (the end facing the opposite side of the outlet 35) of the cylindrical portion 42a of the rotating body 42. ing. As shown in FIG. 6, the discharge hole 41 extends from the front end to the rear end of the nozzle body 42c, and the inflow side opening end 41a facing the outflow port 35 is eccentric with respect to the rotation axis RA. It is located.

In this embodiment, the discharge hole 41 extends straight in parallel to the rotation axis RA from the outflow side opening end 41b facing outward to the inflow side opening end 41a, and the entire discharge hole 41 extends radially outward with respect to the rotation axis RA. It is placed eccentrically so that it is offset from the center. Further, the rear end surface of the nozzle body 42c of the rotating body 42 is provided with three recessed portions 42d arranged at equal intervals in the circumferential direction with respect to the inflow side opening end 41a with the rotation axis RA as the center. . That is, on the rear end surface of the nozzle body 42c of the rotating body 42, one inflow side opening end 41a and three recessed portions 42d are arranged at equal intervals and shifted by 90 degrees in the circumferential direction around the rotation axis RA. has been done.

The rotating body 42 may have a configuration in which a knob 44 for rotational operation is integrally provided on the nozzle body 42c.

The valve holder 37 has a substantially disk shape, and has a plurality of (four) through holes 37a extending in the circumferential direction around the rotation axis RA to allow the contents flowing out from the outlet 35 to flow through the discharge hole 41. They are arranged side by side.

The convex portion 43 protrudes from the outlet 35 side toward the discharge hole 41 side and is provided on the head portion 30 eccentrically with respect to the rotation axis RA. In this embodiment, a pair of convex portions 43 are provided on the front end surface of the valve holder 37 facing the nozzle 40 and are arranged symmetrically across the rotation axis RA. Each convex portion 43 has a cylindrical shape extending parallel to the rotation axis RA, and the length in the direction along the rotation axis RA is longer than the cylindrical portion 42a. Further, the front end portion of each convex portion 43 is chamfered. The chamfered portions of the pair of convex portions 43 have a diameter that allows them to abut the inflow side opening end 41a of the discharge hole 41 over the entire circumference. Further, the amount of eccentricity (distance of eccentricity) of the pair of convex portions 43 with respect to the rotation axis RA is the same as the amount of eccentricity of the inflow side opening end 41a of the discharge hole 41 and the recessed portion 42d with respect to the rotation axis RA.

Therefore, when the rotating body 42 is in the open position, the discharge hole 41 is not blocked by the convex portion 43 and is opened and communicated with the outlet 35 . Therefore, by pressing down the top wall portion 31, the contents stored in the internal space S can be discharged to the outside from the outlet 35 through the discharge hole 41. Further, since the tips of the pair of convex portions 43 are engaged with or arranged in the corresponding concave portions 42d, the rotating body 42 is held in the open position without unexpected rotation.

On the other hand, as shown in FIGS. 7, 8, 9, and 10, the knob 44 is operated to rotate the rotating body 42 by 90 degrees to one side in the circumferential direction about the rotation axis RA. Then, the rotating body 42 is in the closed position. When the rotating body 42 is in the closed position, one of the convex portions 43 faces the inflow side opening end 41a of the discharge hole 41, and its tip abuts the inflow side opening end 41a over the entire circumference to close the discharge hole 41. do. The other convex portion 43 is engaged with or arranged in the corresponding concave portion 42d. Further, since the tips of the pair of convex portions 43 are engaged with or arranged in the inflow side opening end 41a or the corresponding recessed portion 42d, the rotating body 42 is held in the closed position without unexpected rotation.

In this embodiment, since the pair of protrusions 43 are provided symmetrically across the rotation axis RA, the knob 44 is operated to move the rotation body 42 from the open position to the rotation axis RA. When rotated 90 degrees to the other side in the circumferential direction, the rotating body 42 is in the closed position, one protrusion 43 is engaged with or arranged in the recess 42d, and the other protrusion 43 is connected to the discharge hole 41. The discharge hole 41 is closed by facing the inflow side opening end 41a and abutting the entire circumference of the inflow side opening end 41a.

Furthermore, by operating the knob 44 to rotate the rotary body 42 in the closed position by 90 degrees in the circumferential direction around the rotation axis RA, the rotary body 42 is brought into the open position again, and the dispensing tool 1 The discharge container 2 can be brought into a state in which the contents can be discharged.

In this way, according to the discharge tool 1 or the discharge container 2 of this embodiment, the discharge hole 41 can be opened and closed by a simple operation of rotating the rotating body 42 of the nozzle 40.

Furthermore, when the rotating body 42 is in the closed position and the discharge hole 41 is blocked by the convex portion 43, the communication between the discharge hole 41 and the outlet 35 is cut off. Even if the first check valve 50 opens unexpectedly due to an impact or the like, the contents stored in the internal space S of the head section 30 can be prevented from leaking out from the discharge hole 41. can.

Furthermore, in the discharge tool 1 or the discharge container 2 of the present embodiment, the valve holder 37 disposed between the rotating body 42 and the first check valve 50 is provided with the protrusion 43; The configuration can be simplified and the cost of the discharge tool 1 or the discharge container 2 can be reduced.

Since the three recesses 42d are arranged at equal intervals in the circumferential direction with respect to the inflow side opening end 41a as the center, the rotating body 42 can be rotated in the circumferential direction about the rotation axis RA from the open position. The discharge hole 41 can be opened and closed by rotating it in either direction, one side or the other side. Thereby, the discharge hole 41 can be opened and closed more easily.

Furthermore, in the dispensing tool 1 or the dispensing container 2 according to the present embodiment, the content can be discharged by pushing down the top wall portion 31 and elastically deforming the elastically deformable portion 32c. The head portion 30 can function as a pump to discharge the contents without using a pump or a metal spring.

In this case, the valve holder 37 is provided with only one convex portion 43 that is eccentric with respect to the rotation axis RA, and a part of the nozzle body 42c is constituted by an inclined wall 42e. The inclined wall 42e is inclined with respect to the rotation axis RA from the inflow side opening end 41a to the cylindrical portion 42a on the opposite side of the inflow side opening end 41a across the rotation axis RA. It extends. The inclined wall 42e has a substantially constant thickness, and the inner surface 42f of the inclined wall 42e is an inclined surface similar to the inclined wall 42e. Further, the discharge hole 41 is eccentric so that the entire inflow side opening end 41a is shifted from the rotation axis RA, and extends diagonally from the inflow side opening end 41a toward the outflow side opening end 41b.

As shown in FIG. 12, when the rotating body 42 is in the open position, the convex portion 43 is bent toward the rotation axis RA along the inclined wall 42e by contacting the inner surface 42f of the inclined wall 42e. Then, it becomes in a state separated from the inflow side opening end 41a. Therefore, when the rotating body 42 is in the open position, the discharge hole 41 is not blocked by the convex portion 43 and is opened and communicated with the outlet 35 . Therefore, by pressing down the top wall portion 31, the contents stored in the internal space S can be discharged to the outside from the outlet 35 through the discharge hole 41.

On the other hand, as shown in FIG. 14, when the knob 44 is operated to rotate the rotating body 42 by 180 degrees in the circumferential direction around the rotation axis RA, the rotating body 42 is brought to the closed position. When the rotating body 42 is in the closed position, the convex portion 43 separates from the inclined wall 42e, extends straight without contacting the inner surface 42f of the inclined wall 42e, and extends all around the inflow side opening end 41a. They come into contact and close the discharge hole 41.

In this way, even in the modified discharge tool 1 or discharge container 2, the discharge hole 41 can be opened and closed by simply rotating the rotating body 42 of the nozzle 40.
