The operation unit 20 further includes a pair of left and right hanging portions 22 hanging from the operation receiving unit 21, and a connecting portion 23 connecting the lower ends of the hanging portions 22 to each other.
Each hanging portion 22 has a guided rib 24 extending linearly up and down. The guided ribs 24 of the pair of hanging portions 22 face each other. At the lower end of each guided rib 24, a locking projection 24a that slightly protrudes forward is formed.
The connecting portion 23 is formed in a plane view arc shape, and is arranged along the rear surface of the head portion 30.
A guided recess 25 recessed toward the rear is formed on the front surface of the central portion of the connecting portion 23. The guided recess 25 is formed in a dovetail groove shape (a groove shape that is wider toward the inner part of the groove).

The connecting portion 23 is provided with a pressing portion 26 that pushes down the force point portion 56 of the swing member 50 when the operating portion 20 is pushed. The pressing portion 26 projects rearward from the central portion of the connecting portion 23.
More specifically, the pressing portion 26 has a horizontal lower surface, and the pressing portion 56 is pushed down on the lower surface. When the force point portion 56 is pushed down by the pressing portion 26, the swing member 50 swings, so that the portion where the force point portion 56 contacts the pressing portion 26 moves in the front-rear direction. The lower surface of the pressing portion 26 has a certain size in the front-rear direction so that the force point portion 56 can always be pushed down by the horizontal lower surface of the pressing portion 26 during this forward / backward movement.
Since the lower surface of the pressing portion 26 is horizontal, when the operating portion 20 is pushed down at a constant speed, the head portion 30 is also pushed down at a substantially constant speed (however, it is slower than the descending speed of the operating portion 20).

Each member constituting the 80 and the dip tube 93, etc.) are directly or indirectly held by the mounting portion 42.
The axis of the extension pipe 27 and the axis of the head portion 30 (the axis of the inner cylinder portion 33 and the outer cylinder portion 32) extend vertically, respectively.

Here, as described above, the second mounting portion 60 is rotatable relative to the mounting portion 42.
Further, when the second mounting portion 60 rotates with respect to the mounting portion 42, the second mounting portion 60, the swing member 50, the head portion 30, and the operating portion 20 are integrally rotated with respect to the mounting portion 42. It is designed to do. Further, when the operation unit 20 is rotated relative to the container body 11 and the mouth and neck mounting member 15, the head unit 30, the swing member 50, and the second mounting unit 60 are moved to the container body 11 along with the operation unit 20. It is designed to rotate relative to the mouth-neck mounting member 15 and the mounting portion 42. Therefore, the user can use the liquid discharge container 100 by pointing the discharge port 29a of the operation unit 20 in a desired direction.

Of the above configurations, the shaft support portion 64 of the second mounting portion 60, the swing member 50 (the swing portion 51 (first portion 52, the second portion 53, the working surface 55), the bearing portion 57, and the power point portion). 56), the protrusion 38 of the head portion 30, the pressing portion 26 of the operating portion 20, and the like constitute a lever mechanism.

In the case of the present embodiment, the covering portion 70 is composed of the operation portion side cylinder portion 71 and the second cylinder portion 72.
When the liquid discharge container 100 is viewed from the side periphery, the operation unit side cylinder portion 71 and the second cylinder portion 72 overlap each other.
In the present invention, the operation portion side cylinder portion 71 extends from the operation receiving portion 21 toward the mounting portion 42, and the second cylinder portion 72 extends from the mounting portion 42 toward the operation receiving portion 21 side. You may put it out.
That is, the covering portion 70 has a cylindrical operation portion side cylinder portion 71 extending from the operation receiving portion 21 toward the container body 11 side or the mounting portion 42 side, and the operation receiving portion from the container body 11 or the mounting portion 42. It is configured to include a cylindrical second cylinder portion 72 extending toward the 21 side, and when the liquid discharge container 100 is viewed from the outside, the operation unit side cylinder portion 71 and the second cylinder The portions 72 overlap with each other.

More specifically, the operation unit side cylinder portion 71 is inserted into the second cylinder portion 72. The outer peripheral surface of the operation unit side cylinder portion 71 and the inner peripheral surface of the second cylinder portion 72 are close to each other.
By inserting the operation unit side cylinder portion 71 into the second cylinder portion 72, the operation portion 20 can be made more compact, and the outer diameter of the second cylinder portion 72 is expanded downward. Also, the clearance between the operation unit side cylinder portion 71 and the second cylinder portion 72 can be made constant in the vertical direction.
The inner peripheral surface of the second cylinder portion 72 may guide the outer peripheral surface of the operation portion side cylinder portion 71 in a straight line up and down.
As shown in FIG. 2, it is preferable that the second cylinder portion 72 extends beyond the shaft support portion 64 to the operation receiving portion 21 side. That is, it is preferable that the upper end of the second cylinder portion 72 is located above the shaft support portion 64.

The operation on the liquid discharge container 100 is performed by the user pressing the operation receiving unit 21 of the operation unit 20 downward and pushing down the operation unit 20.
In the normal state in which the operation unit 20 is not pushed down, the operation unit 20 and the head unit 30 are respectively located at top dead center due to the urging of the spring body 84 (FIGS. 2 and 6).
When the user pushes down the operation unit 20, a pushing force is transmitted from the operation unit 20 to the head portion 30 via the swing portion 51, and the head portion 30 is pushed down against the urging of the spring body 84 (FIG. 3). , FIG. 7).

More specifically, when the operating portion 20 is pushed down, a force is transmitted from the pushing portion 26 to the force point portion 56, and the swing member 50 swings with the shaft support portion 64 as a fulcrum. That is, the swing member 50 swings in the direction in which the force point portion 56 side descends with the bearing portion 57 as the center of rotation.
Further, when the swing member 50 swings in this way, a force is transmitted from the working surface 55 of each swing portion 51 to each protrusion 38 of the head portion 30, and the head portion 30 urges the spring body 84. It is pushed down against.
As described above, the contact portion of the action surface 55 of the swing portion 51 with the protrusion 38 is located between the bearing portion 57 and the power point portion 56 of the swing portion 51. Therefore, the magnitude of the force required for pushing down the operation unit 20 is reduced as compared with the case where the head unit 30 is directly pushed down. That is, since the head portion 30 is pushed down by pushing down the operation portion 20, the head portion 30 can be pushed down by utilizing the principle of leverage.
As shown in FIGS. 6 and 7, the contact portion of the swing portion 51 with the protrusion 38 on the working surface 55 is located substantially in the middle between the bearing portion 57 and the power point portion 56 of the swing portion 51. Therefore, the magnitude of the force required for pushing down the operation unit 20 is reduced to about ½ as compared with the case where the head unit 30 is directly pushed down.

When the operation unit 20 and the head unit 30 are pushed down in this way, the ascending speed of the operating unit 20 is faster than the ascending speed of the head unit 30, so that the front surface of the hanging portion 22 of the operating unit 20 and the guided rib 24 are The rear surface of the guide rib 37 of the head portion 30 and the guide groove 36 guide the head portion vertically vertically, and the guided recess 25 of the connecting portion 23 of the operation portion 20 is linearly guided vertically by the guide rib 39 of the head portion 30. Will be done.
That is, the liquid discharge container 100 is provided with a guide mechanism that guides the relative movement of the operation unit 20 with respect to the head unit 30 while maintaining the posture of the operation unit 20 when the operation unit 20 is pushed. This guide mechanism includes a guide portion included in the head portion 30 and a guided portion included in the operation portion 20 and guided by the guide portion. In the case of the present embodiment, the guide portion is composed of a guide groove 36, a guide rib 37, and a guide rib 39. Further, the guided portion is composed of a hanging portion 22 and a connecting portion 23.
Here, in the present invention, maintaining the posture of the operation unit 20 means suppressing the change in the posture of the operation unit 20 more than the change in the posture of the rocking member 50, and preferably the operation unit 20. It means keeping the posture constant. In the case of the present embodiment, as described above, the operation unit 20 is guided up and down in a straight line. That is, the posture of the operation unit 20 is maintained constant by the guide mechanism. Therefore, it is possible to realize an operation feeling equivalent to that of a liquid discharge container of a type that directly pushes down the head portion 30.

The covering portion 70 covers the head portion 30 from the upper end to the lower end of the head portion 30. Therefore, the covering portion 70 covers the guide portion from the upper end to the lower end of the guide portion. That is, the covering portion 70 covers the guide portion between both ends of the guide portion in the axial direction.

Further, when the operation portion 20 and the head portion 30 are pushed down, the outer peripheral surface 27a of the extension pipe 27 slides with respect to the inner peripheral surface 73a of the head portion inner flow path 73. That is, the extension pipe 27 is guided up and down in a straight line by the flow path 73 in the head portion. Therefore, the posture of the operation unit 20 can be maintained more reliably. Further, since the operation unit 20 can be guided by the head unit 30 at a position closer to the central axis of the pump mechanism 80, the operation unit 20 can be guided more stably, and the extension pipe 27 and the head can be guided. It is possible to suppress the occurrence of biting with the internal flow path 73. Further, since the outer peripheral surface 27a of the extension pipe 27 slides on the inner peripheral surface 73a of the inner flow path 73 in the head portion, which is the flow path of the liquid 150 (foam in the present embodiment), the surface active action of the liquid 150 causes the outer peripheral surface 27a to slide. , The sliding resistance of the outer peripheral surface 27a with respect to the inner peripheral surface 73a can be suppressed.
As described above, the head portion 30 has an internal flow path 73 in the head portion through which the liquid 150 passes (as bubbles in the present embodiment), and the operation unit 20 has an internal flow in the operation unit through which the liquid 150 passing through the head portion 30 passes.

It passes through 74 and in this order and is discharged from the discharge port 29a.

When the pressing operation on the operation unit 20 is released, the head unit 30 rises according to the urging of the spring body 84 and returns to the normal state. At that time, the operation unit 20 also returns to the position before the pressing operation.
That is, when the head portion 30 rises, the working surface 55 of the swing member 50 is pushed up by the protrusion 38, so that the swing member 50 swings in the direction in which the force point portion 56 side rises with the shaft support portion 64 as a fulcrum. .. When the swinging member 50 swings in this way, the pushing portion 26 of the operating portion 20 is pushed up by the force point portion 56, so that the operating portion 20 rises while being linearly guided up and down by the guide mechanism.
When the head portion 30 rises, the piston guide 87 and the liquid piston 86 rise integrally with the head portion 30, and the liquid 150 in the container body 11 is sucked into the liquid pump section 82 via the dip tube 93. Will be done. Further, when the head portion 30 rises, the gas piston 88 rises along with the piston guide 87, and the outside air is sucked into the gas pump portion 83.

When the operation unit 20 and the head unit 30 rise according to the urging of the cover unit 58, the ascending speed of the operation unit 20 is faster than the ascending speed of the head unit 30, so that the guided portion of the operation unit 20 is the head unit 30. It is guided in a straight line up and down by the guide part of. Further, the extension pipe 27 is guided up and down in a straight line by the flow path 73 in the head portion.

Here, the average flow path area of the flow path 74 in the operation section (that is, the vertical DC path 74a) inside the extension pipe 27 is smaller than the flow path area of the downstream end portion 73b of the flow path 73 in the head section. Therefore, the bubbles generated by the bubble generation unit 92 can be discharged from the discharge port 29a through the flow path 74 in the operation unit without waste.
Here, the average flow path area of the operation section inner flow path 74 inside the extension pipe 27 is the volume of the operation section inner flow path 74 inside the extension tube 27, and the operation section inner flow path 74 inside the extension tube 27. It is the value divided by the length of.
More specifically, in the case of the present embodiment, the average flow path area of the flow path 74 in the operation section inside the extension pipe 27 is smaller than the average flow path area of the flow path 73 in the head section.

Further, as shown in FIG. 2, the contact point between the outer peripheral surface 27a of the extension pipe 27 and the inner peripheral surface 73a of the head portion inner flow path 73 swings in a state where the operation receiving portion 21 is not pushed. It is located closer to the operation receiving portion 21 than the swing shaft (shaft support portion 64) of the portion 51.
Therefore, in the initial stage of the pushing operation to the operation unit 20, the contact area between the outer peripheral surface 27a of the extension pipe 27 and the inner peripheral surface 73a of the head portion inner flow path 73 can be made smaller, and the pushing operation to the operation unit 20 can be made smaller. It is possible to reduce the pushing force required at the initial stage of. In addition, a longer stroke of the operation unit 20 can be suitably secured.

In the case of the present embodiment, the covering portion 70 also covers the entire of each of the extension pipe 27, the head portion 30, the second mounting portion 60, and the mounting portion 42 in the outer circumference around the axis.

Further, the operation receiving unit 21 covers the entire lever mechanism in a plan view. More specifically, the operation receiving portion 21 covers the entire head portion 30, the second mounting portion 60, and the mounting portion 42 in a plan view.

According to the above embodiment, since the liquid discharge container 100 has a lever mechanism, the head portion 30 can be pushed by using the principle of leverage by pushing the operation receiving portion 21.
Then, the liquid discharge container 100 has the swing portion 51 as an axial axis in the axial direction in the one direction and the opposite direction, in a range continuous from the container main body 11 or the mounting portion 42 to the operation receiving portion 21. Since the covering portion 70 is provided to cover the outer periphery of the surroundings, it is possible to realize a good appearance of the liquid discharge container 100.

Further, since the liquid discharge container 100 has a nozzle portion 29 having a discharge port 29a and the nozzle portion 29 is provided integrally with the operation unit 20, the user can push down the operation unit 20 to push down the liquid discharge container 100.
