FIG. 5 is a partial longitudinal sectional view of the discharge container 1 when the contents W are weighed.
The lower end portion of the discharge cylinder main body 92 is an opening / closing part 97 that opens and closes the outlet hole 55 as the discharge cylinder 90 moves up and down. Specifically, as shown in FIG. 1, when the discharge cylinder member 7 is screwed to the measuring cylinder member 3 with the maximum allowance, and the discharge cylinder 90 is disposed at the lowest position, the opening / closing portion 97 is The outlet hole 55 is closed from the inside in the radial direction. As a result, communication between the inside of the discharge cylinder 90 and the discharge hole 95 and the measurement space P is blocked, so that the content W is prevented from leaking from the discharge hole 95.
On the other hand, as shown in FIG. 5, when the discharge cylinder member 7 is screwed to the measuring cylinder member 3 with less than the maximum tightening allowance, and the discharge cylinder 90 is disposed above the lowest position, The opening / closing part 97 opens the outlet hole 55. Accordingly, the inside of the discharge cylinder 90 and the discharge hole 95 and the measurement space P are communicated through the outlet hole 55, so that the contents W can be discharged from the discharge hole 95. The opening amount of the outlet hole 55 increases corresponding to the increase in the upward movement amount of the discharge cylinder 90, and the opening amount of the outlet hole 55 becomes maximum when the discharge cylinder 90 is disposed at the uppermost position.

As shown in FIG. 1, the cap 10 is a member formed of, for example, a synthetic resin material, and the lower end opening is detachably fitted to the upper end 72 of the mounting cap 70.
When the discharge container 1 is not used, the cap 10 is mounted on the upper end 72 of the mounting cap 70 and the discharge hole 95 is closed. At this time, the discharge cylinder member 7 is screwed to the measuring cylinder member 3 with a maximum tightening allowance, and the outlet hole 55 is closed by the opening / closing part 97. Thereby, the inside of the container body 2 is in an airtight state, and leakage of the contents W from the discharge holes 95 is prevented. In the use state of the discharge container 1 (see FIG. 5), the cap 10 is detached from the upper end portion 72 of the mounting cap 70.

(Function)
Next, the operation of the discharge container 1 formed as described above will be described.
As shown in FIG. 5, the cap 10 is detached from the discharge cylinder member 7, and the discharge cylinder member 7 is rotated around the container axis O with respect to the measurement cylinder member 3. As a result, the opening / closing portion 97 of the discharge cylinder member 7 moves upward along the container axis O and opens the outlet hole 55. At this time, the inside of the container body 2 and the outside of the container body 2 are the suction hole 62 of the closing member 60, the inside of the suction tube portion 34, the supply hole 35 of the lower inner plug 30, the measurement space P, and the upper inner plug 50. The lead-out hole 55, the inside of the discharge cylinder 90 and the discharge hole 95 communicate with each other. Thereby, the airtight state is opened inside the container body 2.
Here, when the discharge cylinder member 7 is rotationally moved around the container axis O, a click feeling or sound or the like when the elastic protrusion 85 gets over the protrusion 57 is transmitted to the user (see FIG. 3). ). The user adjusts the opening amount of the outlet hole 55 by recognizing the rotational movement amount of the discharge cylinder member 7 based on a sense such as touch or hearing.

  Subsequently, the container body 2 is pressed with the discharge hole 95 of the discharge container 1 facing upward in the vertical direction to squeeze the container body 2. As a result, the internal pressure of the container body 2 rises, and the content W of the container body 2 flows into the suction cylinder portion 34 through the suction hole 62 of the closing member 60.

  When the internal pressure of the container body 2 further rises, the content W moves upward in the suction cylinder portion 34 and flows into the measurement space P through the supply hole 35 of the measurement cylinder member 3. Then, the contents W are filled in the measuring space P until the liquid level S reaches the height position of the lower end of the supply hole 35. At this time, the height of the liquid level S may be visually confirmed from the outside of the discharge container 1 via the transparent measuring tube main body 40. When the quantitative content W is filled in the measurement space P, the pressing of the container body 2 is stopped, and the squeeze deformation of the container body 2 is released. In addition, when the content W more than fixed quantity flows in into the measurement space P, the liquid level S becomes higher than the height position of the lower end of the supply hole 35. Then, until the liquid level S reaches the height position of the lower end of the supply hole 35, it flows backward from the supply hole 35 and is returned to the inside of the container body 2, and the quantitative content W is filled in the measurement space P. This back flow can be attributed to the weight of the contents W, or to the decompression action in the container body 2 due to the restoring deformation due to the elasticity of the container body 2 when the squeeze deformation is released.

FIG. 6 is a partial longitudinal sectional view of the discharge container 1 when the contents W are discharged.
Subsequently, as shown in FIG. 6, the contents W are discharged onto the discharge target surface H in a posture in which the discharge holes 95 of the discharge container 1 face downward in the vertical direction. At this time, since the contents W in the container body 2 move downward in the vertical direction, the closing member 60 in the container body 2 is disposed outside the contents W.
Then, the container body 2 is pressed to squeeze the container body 2 again. As a result, the internal pressure of the container body 2 rises, and the air G in the container body 2 flows into the suction cylinder portion 34 through the suction hole 62 of the closing member 60 and presses the contents W in the measurement space P. . Then, the contents W are discharged from the discharge hole 95 toward the discharge target surface H outside the discharge container 1 through the outlet hole 55.

According to the present embodiment, the measurement space P that includes the squeeze-deformable container body 2 and that communicates with the container body 2 through the supply hole 35 is defined in the measurement cylinder member 3, and the measurement space P and the discharge hole. 95 is formed so that the container body 2 is squeezed and deformed with its mouth portion 22 facing upward in the vertical direction and its internal pressure is increased. The metering space P is filled with the contents W until it flows into the metering space P through the supply hole 35 of the metering cylinder member 3 and the liquid level S reaches the height position of the supply hole 35. As described above, after the quantitative content W is filled in the measuring space P, the container body 2 is further squeezed with its mouth portion 22 facing downward in the vertical direction. Is applied to the contents W measured as described above through the inside of the supply hole 35 and the measuring cylinder member 3, and the contents W are discharged from the discharge hole 95 through the outlet hole 55.
As described above, since the content W measured in a fixed amount is discharged in a pressurized state, the content W can be discharged quickly with little remaining.

  In addition, since the discharge cylinder member 7 is provided with an opening / closing portion 97 that opens and closes the outlet hole 55 in accordance with the vertical movement along the container axis O direction, the contents are discharged from the outlet hole 95 by closing the outlet hole 55. Can be prevented from being accidentally leaked.

  In addition, a plurality of climbing protrusions 57 are disposed on the measuring cylinder member 3 along the circumferential direction, and the jumping protrusions 57 are circumferentially contacted with the discharge cylinder member 7 while being in sliding contact with the climbing protrusions 57 of the measuring cylinder member 3. Therefore, the discharge cylinder member 7 and the measuring cylinder member 3 are relatively rotated around the container axis O, and the discharge cylinder member 7 is moved vertically with respect to the measurement cylinder member 3. When the elastic protrusion 85 moves over and over the protrusion 57 in the circumferential direction, the rotational movement amount, that is, the opening amount of the outlet hole 55 is recognized by a sense such as tactile sense or hearing. Can do. Therefore, the discharge amount of the contents W can be adjusted and excellent operability can be provided.

  In addition, a closing member 60 that closes the lower end opening 34a of the sucking cylinder portion 34 is mounted, and the suction hole 62 of the closing member 60 is smaller than the inner diameter of the suction cylinder portion 34. Therefore, even if the container body 2 is tilted, the suction hole It is possible to suppress the natural flow of the contents W from 62, and to prevent the contents W in the container body 2 from flowing into the measurement space P through the suction cylinder 62 through the suction hole 62. Accordingly, an accurate amount of the content W is weighed.

FIG. 7 is a partial longitudinal sectional view of the discharge container 1 when the discharge container 1 is horizontally disposed.
By the way, as shown in FIG. 7, when the discharge container 1 is horizontally disposed such that the container axis O of the discharge container 1 is along the horizontal plane L, it is disposed below the closing member 60 in the container body 2 in the vertical direction. Even if the container body 2 is squeezed and deformed in a state in which the portion thus immersed in the contents W, at least one or more suction holes 62 are not immersed in the contents W, and the opening diameter thereof is the suction cylinder portion 34. Therefore, the inflow of the content W into the suction hole 62 is suppressed, and the air G in the container body 2 is supplied to the measurement space P. Further, even if the contents W flow from the suction holes 62 immersed in the contents W due to the squeeze deformation, the squeeze amount (regulation member) and the opening area of the suction cylinder portion 34 and the suction holes 32 By appropriately adjusting the relationship (including the numerical aperture) and the like, the inflowing contents W do not flow into the suction cylinder portion 34 and are designed to flow out from the suction holes 32 not immersed in the contents W. can do.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

  In the embodiment, the protruding protrusion 57 is disposed on the measuring cylinder member 3, the elastic protruding piece 85 is protruded from the discharge cylinder member 7, and the elastic protruding piece 85 moves over the protruding protrusion 57 in the circumferential direction. The rotational movement amount of the discharge cylinder member 7, that is, the opening amount of the outlet hole 55 is recognized based on the click feeling and the sound. On the other hand, for example, a scale may be provided on the outer peripheral surfaces of the measuring cylinder member 3 and the discharge cylinder member 7 so that the rotational movement amount of the discharge cylinder member 7 can be visually confirmed.

FIG. 8 is a partial longitudinal sectional view of the discharge container 1 of the first modification of the embodiment.
In the above embodiment, as shown in FIG. 8, for example, when the body portion 24 of the container body 2 is squeezed and deformed toward the inner side in the radial direction on the lower inner plug 30 of the measuring cylinder member 3, the container body A restricting portion 37 that abuts the second torso portion 24 and restricts the movement of the torso portion 24 of the container body 2 may be provided.
In this case, the restricting portion 37 is formed in a cylindrical shape extending downward from the lower end of the outer cylinder 31 of the lower inner plug 30, and is disposed outside the suction cylinder portion 34 along the container axis O. ing. Thereby, the amount of squeeze when the body part 24 of the container body 2 is squeezed and deformed is restricted, and the contents W of the container body 2 can be prevented from being pressurized more than necessary. Therefore, the contents W can be prevented from being discharged from the discharge holes 95 when the contents W are weighed. In addition, you may provide the control part 37 in the container body 2 side. For example, by restricting the inner peripheral surface of the container body 2 inward in the radial direction, the opposing inner peripheral surfaces come into contact with each other, and a restricting portion 37 that restricts the movement of the body portion 24 of the container body 2 may be provided. .

In FIG. 9, the state in which the discharge holes 95 of the discharge container 1 are oriented downward in the vertical direction and the contents W are discharged to the discharge target surface H is illustrated.
In the above embodiment, as shown in FIG. 9, for example, the closing member 60 (see FIG. 1) does not have to be provided in the lower end opening 34 a of the suction cylinder portion 34.
Even in this case, by squeezing the container body 2, the internal pressure of the container body 2 rises, and the air G in the container body 2 flows from the lower end opening 34 a of the suction cylinder portion 34. Thereby, since the content W is discharged from the discharge hole 95 in a pressurized state, the same effect as the embodiment can be obtained. In order to prevent the contents W from flowing into the inside of the suction cylinder part 34 from the lower end opening 34a of the suction cylinder part 34 at the time of discharging the contents W, the inner diameter of the suction cylinder part 34 is set to the suction of the embodiment. It is preferable to make it smaller than the inner diameter of the cylindrical portion 34 (see FIG. 1), or at least make the inner diameter of the lower end opening 34a of the suction cylindrical portion 34 smaller than the inner diameter of the suction cylindrical portion 34 of the embodiment.

  In addition, it is possible to appropriately replace the constituent elements in the above-described embodiments with well-known constituent elements without departing from the spirit of the present invention, and the above-described modifications may be appropriately combined.
