The annular portion 27 and two horizontal portions 29 adjacent to each other in the circumferential direction define a circulation port 16 </ b> A that communicates the inside in the radial direction of the circulation member 12 and the inside of the container 2. Further, the insertion hole 16 </ b> B is defined by the two horizontal portions 29 adjacent to the annular portion 27 in the circumferential direction and the lower end portion of the upper tube portion 23. Therefore, a plurality (four in this embodiment) of the circulation ports 16A and the insertion holes 16B are formed at regular intervals with an interval in the circumferential direction.

The flow member 12 has a hook-like part 31 that curves upward as it goes radially outward, and a cylindrical part 32 that hangs downward from the hook-like part 31. The flange-shaped part 31 and the cylindrical part 32 are arranged coaxially with the central axis O.
The opening formed in the central portion in the radial direction of the bowl-shaped portion 31 is a spout 5A that communicates the radially inner side of the cylindrical portion 32 and the radially inner side of the bowl-shaped portion 31.

  The cylindrical portion 32 has a cylindrical shape, and a plurality of (four in the present embodiment) engagement leg portions 33 are provided downward at the lower end of the cylindrical portion 32 at equal intervals in the circumferential direction. Projecting. The engagement leg portion 33 is formed at a position corresponding to the insertion hole 16B in a top view, and an engagement protrusion portion 33A that protrudes radially outward is formed at the lower end portion thereof. In addition, the engagement leg portion 33 engages with a step portion between the lower end of the upper cylinder portion 23 and the upper end of the protruding cylinder portion 24 in the mounting cylinder portion 15 through the corresponding insertion hole 16B. Thereby, the distribution member 12 is attached to the mounting member 11.

The seal member 6 has a cylindrical shape, and has a head portion 41, a trunk portion 42, and a leg portion 43 in order from the top to the bottom. The seal member 6 is disposed between the spout 5A of the bowl-shaped portion 31 and the bottom wall portion 25 of the pedestal portion 16. The head portion 41, the body portion 42, and the leg portion 43 are disposed coaxially with the central axis O.
The outer peripheral edge of the upper surface of the head 41 is in contact with the edge of the spout 5A of the bowl 31. Further, an engaging groove portion 41 </ b> A that engages with an engaging flange portion 53 (described later) of the pressing member 7 is formed on the inner peripheral surface of the center portion of the head portion 41 in the vertical direction. Note that the outer peripheral edge of the head 41 may abut against the edge of the spout 5A of the bowl-shaped portion 31 in an upward biased state.

The outer diameter of the trunk portion 42 is smaller than the outer diameter of the head portion 41.
The leg portion 43 has a cylindrical shape whose inner diameter is larger than the inner diameter of the trunk portion 42, and is thinner in the radial direction than the head portion 41 and the trunk portion 42. The lower end of the leg portion 43 is in contact with the peripheral edge portion of the bottom wall portion 25, and the outer peripheral surface of the leg portion 43 is in contact with the radially inner surface of the upright portion 28 of the connection portion 26. For this reason, in the pedestal portion 16, a space radially inward of the upright portion 28 of the connection portion 26 and a space radially outward of the upright portion 28 are separated by the leg portion 43.

The pressing member 7 includes a support column 51 and a top plate unit 52 that is connected to the upper end of the support column 51. The support column 51 and the top plate 52 are arranged coaxially with the central axis O.
The column portion 51 has a columnar shape and is inserted through the spout 5A of the bowl-shaped portion 31. And the upper end part of the support | pillar part 51 protrudes upwards rather than 5 A of spouts. In addition, the seal member 6 is externally fitted over the entire periphery of a portion of the support column 51 located below the spout 5A. Furthermore, a pair of engaging flange portions 53 projecting outward in the radial direction is formed at the center in the vertical direction of the support column 51, and directed outward in the radial direction at the lower end of the support column 51. A bulging portion 54 that bulges out is formed.

Further, the support column 51 is formed with a pair of introduction grooves (grooves) 51A extending from the upper end of the support column 51 to the upper end of the bulging portion 54 along the vertical direction. The pair of introduction groove portions 51 </ b> A is formed on the opposite side in the radial direction across the central axis O. The introduction groove 51 </ b> A defines an air introduction path 55 between the inner circumferential surface of the seal member 6. The upper end of the air introduction path 55 is located above the spout 5A, but the upper surface of the bulging portion 54 is connected to the inner peripheral surface of the leg portion 43 and the inner peripheral surface of the trunk portion 42 in the seal member 6. Therefore, the communication between the outside of the dispenser 1 and the inside of the container 2 is blocked.
Similarly to the bowl-shaped portion 31, the top plate portion 52 is curved so as to go upward as it goes outward in the radial direction. A space is formed between the lower surface of the top plate portion 52 and the upper surface of the bowl-shaped portion 31, and the content flowing through the spout 5 </ b> A flows along the upper surface of the bowl-shaped portion 31.

Next, a method for dispensing contents by the dispenser 1 configured as described above will be described.
First, as shown by an arrow A in FIG. 5, when the pressing member 7 is pushed in with the container 2 equipped with the dispenser 1 tilted, the column portion 51 of the pressing member 7 and the head 41 of the seal member 6 are connected. Since they are engaged, the force for pushing the push-down member 7 is transmitted to the seal member 6. And since the leg part 43 is seated on the bottom wall part 25 of the base part 16, the sealing member 6 is contracted and deformed by the pushing force, and the head part 41 of the sealing member 6 is the spout 5A of the bowl-shaped part 31. The spout 5 </ b> A is opened away from the edge. Thus, the sealing member 6 changes from a closed posture in which the head 41 as shown in FIGS. 1 and 3 closes the spout 5A to a pouring posture in which the spout 5A is opened as shown in FIG. Thereby, the inside of the container 2 and the outside of the extractor 1 communicate with each other through the outlet 5A and the extraction path 5B. Further, the step portion between the inner peripheral surface of the leg portion 43 and the inner peripheral surface of the trunk portion 42 in the seal member 6 is separated from the upper surface of the bulging portion 54. Thereby, the air introduction path 55 connects the inside of the container 2 and the outside of the extractor 1. In FIG. 5, the body portion 42 of the seal member 6 is elastically deformed, but the spout 5 </ b> A may be opened by elastically deforming the head portion 41 and the leg portion 43.

The contents in the container 2 pass through the pouring path 5B along the inner peripheral surface of the cylindrical portion 32 of the flow member 12, and are poured out from the spout 5A. Then, the contents poured out from the spout 5A are poured out from the dispenser 1 through the gap between the bowl-shaped portion 31 of the flow member 12 and the top plate portion 52 of the pressing member 7. In this way, the contents of the container 2 are poured out.
Further, the air outside the dispenser 1 enters the air introduction path 55 through the gap between the bowl-shaped part 31 of the flow member 12 and the top plate part 52 of the pressing member 7, and this air introduction path 55. Is introduced into the container 2 through the communication port 25A. In this way, air replacement between the contents of the container 2 and the external air is performed. Note that the air replacement may be performed by introducing air from the outside of the dispenser 1 through a portion of the extraction channel 5B where the contents are not circulating.
At this time, since the contents are poured out from between the bowl-shaped portion 31 and the top plate portion 52 formed over the entire circumference, the tilt directionality of the container is not limited, and the operability is excellent.

When the pressing of the pressing member 7 is released, the sealing member 6 is restored and deformed, and the head portion 41 of the sealing member 6 comes into contact with the edge of the spout 5A of the bowl-shaped portion 31. Thereby, 5 A of spouts are obstruct | occluded and communication with the inside of the container 2 and the exterior of the extractor 1 is interrupted | blocked. Further, the step portion between the inner peripheral surface of the leg portion 43 and the inner peripheral surface of the trunk portion 42 in the seal member 6 is in contact with the upper surface of the bulging portion 54. Thereby, the communication between the inside of the container 2 and the outside of the extractor 1 by the air introduction path 55 is blocked.
As described above, the contents in the container 2 are poured out.

According to the dispenser 1 configured as described above, the seal member 6 is elastically pressed between the closed posture and the dispensed posture by pressing down the push-down member 7 that protrudes upward from the spout 5A. Since the opening and closing operation of the spout 5A can be performed by deforming, the operability of the dispenser 1 can be improved without increasing the number of parts.
Further, when the seal member 6 is in the pouring posture, air replacement can be performed between the outside of the pouring device 1 and the inside of the container 2 while pouring the contents from the pouring port 5A.

In addition, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the meaning of this invention.
For example, the mounting member is configured to be screwed into the mouth portion of the container, but may have other configurations such as a configuration in which the mounting member is fitted to the mouth portion. Moreover, although the mounting member is mounted directly on the mouth, it may be attached to the mouth using another member.
The dispensing member includes the mounting member and the flow member, but the mounting member and the flow member may be integrally formed.
The pouring member may have another structure as long as the pouring path having the pouring port is formed and the base member is provided.
The seal member is externally fitted over the entire length of the column portion of the pressing member, but may have another structure as long as it is a structure that engages with the pressing member and closes the spout in the closed position.
The pressing member has a flat plate portion that has a circular bowl shape, but may have other structures such as a structure that does not have a flat plate portion as long as it is a structure that is partially positioned above the spout. not good.

  According to the present invention, industrial applicability is recognized for the dispenser that has improved operability without increasing the number of parts.
