  However, in the above-described conventional dispensing container, when the container body tilted to dispense the content liquid is returned to the upright posture, the content liquid drips from the upper end of the dispensing cylinder along the outer peripheral surface of the dispensing cylinder. It may be dropped. In this case, there is a possibility that the content liquid that hangs down on the outer periphery of the dispensing tube may accumulate on the upper surface of the support wall described above or may drop from the upper surface of the support wall along the outer peripheral surface of the screwed tube. Therefore, in the above-described dispensing container, for example, the content liquid may adhere to the finger or the like when the overcap is removed, and there is a possibility that it becomes unsanitary when used.

  The present invention has been made in consideration of the above-described conventional problems, and an object of the present invention is to provide a dispensing container that can continue to be used in a sanitary manner even if the content liquid drips from the upper end of the dispensing cylinder. Yes.

  A dispensing container according to the present invention is a dispensing container comprising: a container body that contains a content liquid; an inner stopper attached to a mouth of the container body; and a dispensing cylinder that dispenses the content liquid. The inner plug is provided with an inner cylinder disposed on the inner side of the mouth portion, and the extraction cylinder is inserted into the inner cylinder so as to be movable in the axial direction. A liquid reservoir part surrounded by an inner peripheral surface of the inner plug and a liquid recovery path for communicating the liquid reservoir part with the inside of the container body are formed on the outer periphery, respectively, Are disposed below the opening end of the liquid recovery path on the container body side, and the opening end is closed by the relative movement of the dispensing tube relative to the inner plug in the axial direction. It is characterized in that a sealing portion is provided.

  Due to such a feature, when the content liquid is poured out by tilting the container body, the dispensing cylinder is previously moved relative to the inner plug in the axial direction and pulled up in advance. As a result, the sealing portion of the dispensing cylinder closes the opening end on the container body side of the liquid recovery path that allows the liquid reservoir to communicate with the inside of the container body. Thereafter, by tilting the container body, the content liquid in the container body is poured out from the upper end of the dispensing cylinder through the dispensing cylinder. At this time, since the opening end of the liquid recovery path on the container body side is closed by the seal portion, the content liquid in the container body does not flow into the liquid recovery path, and leakage of the content liquid from the liquid recovery path is prevented. Is done. Then, the container body tilted for pouring the content liquid is returned to the upright posture to stop the content liquid pouring. At this time, when the content liquid drips from the upper end of the dispensing cylinder, the content liquid drips into the liquid reservoir and flows into the liquid recovery path from the liquid reservoir. At this time, since the opening end of the liquid recovery path on the container body side is closed by the seal portion, the dripping content liquid accumulates in the liquid recovery path, and the content liquid that could not flow into the liquid recovery path is liquid. Accumulate in the reservoir. Subsequently, the dispensing cylinder pulled up as described above is moved downward relative to the inner plug in the axial direction and pushed down. Accordingly, the seal portion is separated from the opening end of the liquid recovery path on the container body side, and the opening end of the liquid recovery path on the container body side is opened. As a result, the content liquid accumulated in the liquid recovery path flows into the container main body, and the content liquid accumulated in the liquid reservoir flows into the container main body through the liquid recovery path. That is, the content liquid dripping from the upper end of the dispensing cylinder is collected in the container body through the liquid collection path.

Further, the pouring container according to the present invention includes an overcap that covers the inner plug and the pouring tube and is removable on the upper side in the axial direction. The overcap is provided on the pouring tube. It is preferable that a second engagement portion that is detachably engaged with the first engagement portion is provided.
Thereby, when removing the overcap in the axial direction upper side, since the overcap and the extraction cylinder are engaged via the first and second engaging portions, the extraction cylinder is pulled up together with the overcap, The dispensing tube moves axially upward relative to the inner plug. Thereby, as above-mentioned, the opening end by the side of the container main body of a liquid recovery path is obstruct | occluded by the sealing part of the extraction | pouring cylinder.
On the other hand, when the removed overcap is reattached, the dispensing cylinder is pushed down together with the overcap via the first and second engaging portions, and the dispensing cylinder is relatively axially lowered with respect to the inner plug. Moving. As a result, as described above, the seal portion of the dispensing cylinder is separated from the opening end of the liquid recovery path on the container body side, and the opening end of the liquid recovery path on the container body side is opened.

Further, in the dispensing container according to the present invention, the bottom surface of the liquid reservoir is inclined downward from the radially outer side toward the opening end on the liquid reservoir side of the liquid recovery path on the radially inner side. preferable.
As a result, the liquid content dripping into the liquid reservoir flows from the radially outer side toward the radially inner side along the inclined bottom surface and is guided to the opening end on the liquid reservoir side of the liquid recovery path.

Moreover, it is preferable that the pouring container which concerns on this invention is provided with the folding | returning part inclined toward the radial inside at the upper end part of the outer wall part of the said liquid reservoir part.
As a result, when the content liquid is poured out from the upper end of the dispensing cylinder by tilting the container body, the content liquid remaining in the liquid reservoir portion travels along the radially inner wall surface of the liquid reservoir portion, and the upper end of the wall surface. Even if it flows to the side, it is easy to collect at the folded-back part and does not sag easily.

  According to the pouring container according to the present invention, even if the content liquid drips from the upper end of the pouring cylinder, the dripped content liquid is once stored in the liquid reservoir, and then passes through the liquid recovery path and the container main body. Since it is collected inside, the contamination of the inner stopper due to the dripping content liquid can be reduced, and it can be used in a sanitary manner.

The insertion cylinder part 53 is a cylindrical cylinder part having a smaller diameter than the extraction cylinder 4 (extraction cylinder body 40). The insertion cylinder portion 53 is inserted inside the extraction cylinder body 40 and is undercut fitted to the extraction cylinder body 40. More specifically, a convex second engagement portion 55 protruding outward in the radial direction is formed at the lower end portion of the insertion tube portion 53 over the entire circumference. In addition, it is engaged with the first engagement portion 43 of the dispensing cylinder body 40 so as to be disengageable from the lower side in the axial direction.

  Next, the operation of the above-described dispensing container 1 will be described.

  First, as shown in FIG. 2, the overcap 5 is relatively rotated around the axis O with respect to the container body 2 (mouth portion 20), and the overcap 5 screwed to the mouth portion 20 is moved upward in the axial direction. . At this time, since the second engagement portion 55 of the overcap 5 is engaged with the first engagement portion 43 of the dispensing tube 4 from below, the dispensing tube 4 and the overcap 5 are axially upper. The extraction cylinder 4 moves upward in the axial direction relative to the inner cylinder 33 while sliding along the inner peripheral surface of the inner cylinder 33. And the upper surface of the seal part 45 provided in the lower end part of the extraction | pouring cylinder 4 closely_contact | adheres to the lower end surface of the inner cylinder 33, and is formed between the outer peripheral surface of the extraction | injection cylinder 4, and the inner peripheral surface of the inner cylinder 33. The open end of the liquid recovery path 7 on the container body 2 side is closed.

  Subsequently, after rotating the overcap 5 until the engagement between the male screw 21 of the mouth 20 and the female screw 54 of the overcap 5 is released, the overcap 5 is pulled up and removed from the mouth 20. At this time, since the seal portion 45 of the dispensing cylinder 4 is locked to the lower end surface of the inner cylinder 33, the second engagement portion 55 of the overcap 5 gets over the first engagement portion 43 of the dispensing cylinder 4. The first engaging portion 43 moves upward and the first and second engaging portions 43 and 55 are disengaged. Thereby, the insertion cylinder part 53 of the overcap 5 is pulled out from the extraction cylinder 4, and the upper end of the extraction cylinder 4 is opened. Further, the lower end portion of the dispensing cylinder main body 40 is fitted into the inner cylinder 33, whereby the dispensing cylinder 4 is held at the pulling position shown in FIG. 2, and the liquid recovery path 7 is sealed by the seal portion 45 of the dispensing cylinder 4. The state where the open end on the container body 2 side is closed is maintained.

  Next, the container body 2 with the overcap 5 removed is tilted. Thereby, the content liquid in the container main body 2 passes through the pouring cylinder 4 and is poured out from the upper end (the pouring part 42) of the pouring cylinder 4. At this time, since the opening end of the liquid recovery path 7 on the container body 2 side is closed by the seal portion 45 as described above, the content liquid in the container body 2 does not flow into the liquid recovery path 7 and the liquid recovery Leakage of the content liquid from the path 7 is prevented. In addition, if the content liquid adheres to the inner surface of the liquid reservoir 6, the content liquid is the inner wall surface (inner circumference of the rising cylinder 34) on the radially outer side of the liquid reservoir 6 when the container body 2 is tilted. The rising portion 34a is formed at the upper end portion of the rising cylinder 34, so that the content liquid is easily collected at the turning portion 34a. It is difficult for the liquid to drip from the top of the top.

  Subsequently, the container body 2 tilted for pouring the content liquid is returned to the upright posture to stop the pouring of the content liquid. At this time, when the content liquid drips from the pouring portion 42, the content liquid travels along the outer peripheral surface of the pouring cylinder body 40 or falls from the pouring portion 42 and drips into the liquid reservoir 6. Then, the content liquid dripping into the liquid reservoir flows from the radially outer side to the radially inner side along the bottom surface of the inclined liquid reservoir portion 6 (the upper surface of the tapered ceiling wall portion 32). The liquid recovery path 7 is formed in the liquid recovery path 7 and is led to the opening end on the liquid reservoir 6 side and flows into the liquid recovery path 7. At this time, since the opening end of the liquid recovery path 7 on the container body 2 side is closed by the seal portion 45, the dripping content liquid is accumulated in the liquid recovery path 7 and cannot flow into the liquid recovery path 7. The stored content liquid is accumulated in the liquid reservoir 6.

  Next, the removed overcap 5 is put on the mouth portion 20, and the insertion tube portion 53 of the overcap 5 is inserted into the extraction tube 4. At this time, the second engagement portion 55 of the overcap 5 is engaged with the first engagement portion 43 of the dispensing cylinder 4 from above, and the first and second engagement portions 43 and 55 are used for pouring. The outlet cylinder 4 is pushed down together with the overcap 5, and the extraction cylinder 4 moves relative to the inner plug 3 in the axially lower side. As a result, the seal portion 45 of the dispensing cylinder 4 is lowered and separated from the lower end surface of the inner cylinder 33, and the opening end of the liquid recovery path 7 on the container body 2 side is opened. As a result, the content liquid accumulated in the liquid recovery path 7 flows into the container main body 2 and the content liquid accumulated in the liquid reservoir 6 flows into the container main body 2 through the liquid recovery path 7. That is, the content liquid dripping from the upper end of the dispensing cylinder 4 is collected in the container body 2 through the liquid collection path 7.

  Subsequently, the overcap 5 is relatively rotated around the axis O with respect to the container body 2 (mouth portion 20), and the overcap 5 is screwed into the mouth portion 20. At this time, as the overcap 5 is tightened and lowered in the mouth portion 20, the dispensing cylinder 4 is pushed down together with the overcap 5 via the first and second engaging portions 43 and 55, and the dispensing cylinder 4 4 moves axially downward relative to the inner plug 3. Then, when the locking portion 44 of the dispensing cylinder 4 is locked to the upper end surface of the inner cylinder 33, the relative movement of the dispensing cylinder 4 to the lower side with respect to the inner plug 3 is restricted, and the second engagement of the overcap 5 is restricted. The joining portion 55 gets over the first engaging portion 43 of the dispensing cylinder 4 and moves to the lower side of the first engaging portion 43. At this time, the lower end part of the seal cylinder part 52 is fitted inside the upper end part of the fitting cylinder 30, and the gap between the lower end part of the seal cylinder part 52 and the upper end part of the fitting cylinder 30 is sealed.

  According to the pouring container 1 having the above-described configuration, even if the content liquid drips from the upper end of the pouring cylinder 4, the dripped content liquid is once stored in the liquid reservoir 6, and then the liquid recovery path 7. Since it passes through the container body 2 and is collected, it is possible to reduce the contamination of the inner plug 3 due to the dripping content liquid, and to continue using the dispensing container 1 in a sanitary manner.

  Further, the overcap 5 is provided with a second engagement portion 55 that is detachably engaged with the first engagement portion 43 of the dispensing cylinder 4 from the lower side in the axial direction. When removing the overcap 5, the dispensing cylinder 4 moves upward in the axial direction, and when the removed overcap 5 is reinstalled, the dispensing cylinder 4 moves together with the overcap 5 in the axially downward direction. The trouble of pulling up or pushing down the outlet cylinder 4 by an operation different from the opening / closing operation of the overcap 5 can be omitted, and the operability of the dispensing container 1 can be improved.

  Further, the bottom surface of the liquid reservoir 6 (the upper surface of the top wall 32) is inclined toward the opening end side of the liquid recovery path 7 on the liquid reservoir 6 side, and the content liquid dripping into the liquid reservoir 6. Is guided along the inclined bottom surface of the liquid reservoir 6 to the opening end of the liquid recovery path 7 on the side of the liquid reservoir 6, so that the content liquid in the liquid reservoir 6 actively flows into the liquid recovery path 7. The dripping content liquid can be efficiently collected in the container body 2.

  Further, when the content liquid in the container main body 2 is poured by tilting the container main body 2, even if the content liquid remaining in the liquid reservoir 6 flows to the upper end side of the rising cylinder 34, the content liquid will rise. Since it is easy to collect in the folding | returning part 34a of the upper end of the pipe | tube 34, and it is hard to drip from the upper end of the standing pipe | tube 34, the dripping of the content liquid in the liquid storage part 6 at the time of pouring of a content liquid can be suppressed.
