Description

  The present invention relates to a metering dispenser.

When a fixed amount of liquid is measured from a container in which the liquid is stored, generally, a fixed amount of liquid is poured into a measuring cup prepared separately from the container and measured. However, this method is inconvenient because the measuring cup is lost or needs to be washed every time the measuring cup is used.
Therefore, a metering dispenser having a hollow capsule-like member that is attached to the mouth of the container and filled with liquid from the container has been proposed (see, for example, Patent Document 1). This metering dispenser includes a capsule-like member attached to the mouth, a plug body that can be reciprocated up and down with respect to the capsule-like member, and the plug body attached to the plug body by its weight with respect to the capsule-like member. And a weight that reciprocates. The plug body is formed with a flow path that can communicate with the inside of the capsule member by moving the plug body up and down relative to the capsule member.

  In this metering dispenser, first, the container in an upright state is inverted and the stopper is moved with respect to the capsule-like member by the action of the weight, and the container and the capsule-like member are passed through the passage of the stopper. Communicate with the inside. Thereby, the liquid in the container is filled in the capsule-shaped member. At this time, the plug closes the spout of the capsule member. Therefore, the liquid filled in the capsule-shaped member is not poured out. Thereafter, the liquid in the capsule-shaped member is extracted by pushing up the stopper while the container is in an inverted state to open the spout. In this way, a certain amount of liquid is weighed and dispensed from the container.

  However, the following problems remain in such a metering dispenser. That is, in the above-mentioned metering dispenser, it is necessary to push up the plug to open the spout, so that it is required to further improve the operability.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide a metering dispenser with further improved operability.

The present invention employs the following means in order to solve the above problems. That is, the metering dispenser of the present invention is a metering dispenser that is attached to the mouth portion of a container that contains the contents, and is provided in the attaching tube portion that is attached to the mouth portion and the attaching tube portion. And a hollow outer member that is movably fitted to the inner member and forms a filling space with the inner member, and the inner member communicates with the mounting cylinder. A communication passage, a communication portion formed with a communication port communicating with the communication passage and the filling space, and a plug portion for opening and closing a spout formed in the outer member for pouring the contents of the filling space. The outer member has a gap between a filling position where the communication port is opened and the spout is closed, and a pouring position where the communication port is closed and the spout is opened. are fitted to the inner member reciprocally moving the tip of the plug body portion, the outer portion It characterized that you positioned inside the filling space than the tip.

In this invention, since the outer member fitted on the inner member is reciprocated to measure and dispense the contents, the operability of the metering and dispensing operation is improved compared to the case of operating the inner member. . That is, when the outer member is positioned at the filling position, the contents in the container are filled into the filling space through the mounting cylinder portion, the communication path, and the communication port because the communication port is open. Since it is obstruct | occluded by the plug part, it is not poured out from the spout. As a result, the filling space is filled with a predetermined volume of contents. Then, when the outer member is moved toward the pouring position, the contents of the filling space are poured out through the pouring port because the communication port is closed and the pouring port is opened. Therefore, the content in the container is not filled into the filling space through the communication port when the spout is opened, and only a fixed amount corresponding to the volume of the filling space is poured out from the spout.
As described above, since a certain amount of contents can be measured and dispensed simply by reciprocating the outer member exposed to the outside, the operability of the metering dispenser is improved.

In the metering dispenser of the present invention, an intermediate position where the communication port and the dispensing outlet are closed may be set between the filling position and the dispensing position.
In this invention, when the outer member is moved from the filling position to the pouring position, the contents in the container are configured such that the pouring opening is opened after closing the communication port and the pouring port at the intermediate position. When the spout is opened, the filling space is not filled through the communication port, and a certain amount of pouring according to the volume of the filling space is more reliably performed.

In the metering dispenser of the present invention, it is preferable that the outer member has a sliding cylinder portion that slides along the outer peripheral surface of the inner member.
In the present invention, since the outer member is guided by the sliding cylinder portion, the outer member can be stably reciprocated. Therefore, the operability of the metering dispenser is further improved.

Moreover, it is preferable that the metering dispenser of the present invention includes a first stop portion that stops the outer member at the filling position, and a second stop portion that stops the outer member at the discharge position.
In this invention, since the outer member is stopped at the filling position and the dispensing position, the reciprocating movement of the outer member with respect to the inner member is stably performed, and the operability of the metering dispenser is further enhanced.

In the metering dispenser of the present invention, the inner member has a columnar shape or a cylindrical shape, and has a first screw portion formed on an outer peripheral surface of the plug portion, and the outer member is the first member. It is preferable to have a second screw portion that is screwed with the screw portion, and to reciprocate along the central axis by rotating around the central axis of the inner member.
In this invention, since the outer member is reciprocated by rotation around the central axis, it is possible to prevent the outer member from moving along the central axis by the weight of the outer member filled with the contents. This further improves the operability of the metering dispenser.

In the metering dispenser of the present invention, it is preferable that an operation portion capable of operating the outer member with respect to the inner member is provided on the outer peripheral surface of the outer member.
In this invention, an outer member can be easily operated with an operation part.

  According to the metering dispenser according to the present invention, a certain amount of contents can be weighed and dispensed only by reciprocating the outer member exposed to the outside after filling the contents into the filling space. The operability of the ejector is further enhanced.

Further, on the upper surface of the annular flat surface portion 25, an annular fitting projection 25 </ b> A that sandwiches the mouth portion 3 together with the mounting cylinder portion 11 is formed so as to protrude upward in the radial direction from the mounting cylinder portion 11. .
The cylindrical portion 26 has a cylindrical shape in which a communication passage 26 </ b> A communicating with the inside of the mounting cylinder portion 11 is formed. The cylindrical portion 26 extends downward along the central axis O from the inner edge of the annular flat surface portion 25. Yes. A plurality of communication ports 26 </ b> B communicating the communication passage 26 </ b> A and the outside of the communication portion 21 are formed at the lower end portion of the cylindrical portion 26 at intervals in the circumferential direction.

The plug body portion 22 has a top cylindrical shape extending downward along the central axis O, and is connected to the lower end of the cylindrical portion 26. The plug portion 22 includes a substantially disc-shaped top plate portion 27 connected to the lower end of the cylindrical portion 26, and a cylinder extending downward along the central axis O from the radial outer edge of the top plate portion 27. And a body part 28.
A plurality of circulation ports 28 </ b> A are formed at the lower end portion of the cylindrical body portion 28 at intervals in the circumferential direction. The cylindrical body portion 28 has a cylindrical shape, but may have a solid structure such as a columnar shape.

The outer cylinder portion 23 has a substantially cylindrical shape along the central axis O, and extends downward along the central axis O from the outer edge portion on the lower surface of the annular flat surface portion 25. Further, a first stop convex portion (second stop portion) 23A that protrudes radially inward is formed at the lower end of the outer cylinder portion 23 over the entire circumference.
The inner member 12 is formed integrally with the mounting cylinder portion 11.

The outer member 13 is externally fitted to the cylindrical portion 26 and the cylindrical body portion 28, and is provided with a first sliding cylindrical portion (sliding cylindrical portion) 31, which is continuously provided from the upper side along the central axis O, and a filling portion. 32 and a second sliding cylinder part (sliding cylinder part) 33.
The first sliding cylinder portion 31 has a substantially cylindrical shape extending along the central axis O, and is disposed between the outer peripheral surface of the cylindrical portion 26 and the inner peripheral surface of the outer cylindrical portion 23. . The inner diameter of the first sliding cylinder portion 31 is substantially equal to the outer diameter of the cylindrical portion 26. For this reason, the first sliding cylinder part 31 is in sliding contact with the outer peripheral surface of the cylindrical part 26 between the cylindrical part 26 and the outer cylinder part 23.

Moreover, the length along the central axis O of the 1st sliding cylinder part 31 is equivalent to the length of the outer cylinder part 23, and is longer than the communicating port 26B. That is, the 1st sliding cylinder part 31 obstruct | occludes the communication port 26B by moving along the central axis O, and covering the communication port 26B.
Furthermore, the 2nd stop convex part 31A which protrudes toward radial direction outward is formed in the upper end of the 1st sliding cylinder part 31 over the perimeter. As described above, the first sliding cylinder portion 31 has the filling position where the upper end of the first sliding cylinder portion 31 hits the lower surface of the annular flat surface portion 25 and the second stop convex portion 31A of the first sliding cylinder portion 31 outside. It can be reciprocated up and down along the central axis O between the extraction position locked to the first stop convex portion 23 </ b> A of the cylindrical portion 23.

The filling portion 32 has a hollow substantially oval shape along the central axis O, and the center portion bulges outward in the radial direction from both upper and lower ends. In addition, a filling space 32A that can communicate with the communication passage 26A through the communication port 26B is formed inside the filling portion 32. The filling part 32 has an upper end connected to the lower end of the first sliding cylinder part 31 and a lower end connected to the upper end of the second sliding cylinder part 33. In addition, a spout 13 </ b> A that connects the filling space 32 </ b> A and the outside of the outer member 13 is formed at the lower end of the filling portion 32. Further, an operation portion 32B protruding outward in the radial direction is formed on the outer peripheral surface of the central portion of the filling portion 32 over the entire circumference.
The filling portion 32 is formed by fitting upper and lower members 34 and 35 that are divided into two parts up and down around a central portion along the central axis O. Here, the upper member 34 is formed integrally with the first sliding cylinder part 31, and the lower member 35 is formed integrally with the second sliding cylinder part 33.

The second sliding cylinder portion 33 has a substantially cylindrical shape extending along the central axis O, and is disposed on the outer peripheral surface of the cylinder portion 28. The inner diameter of the second sliding cylinder part 33 is equal to the outer diameter of the cylinder part 28. For this reason, the second sliding cylinder part 33 is in sliding contact with the outer peripheral surface of the cylinder part 28.
As the first and second sliding cylinder portions 31 and 33 move along the central axis O, one of them covers the communication port 26B or the flow port 28A, and the communication port 26B and the flow port 28A are covered. Do not open at the same time. Furthermore, if the 1st and 2nd sliding cylinder parts 31 and 33 move to the extraction position from a filling position, they will not open | release the distribution port 28A until it covers the communication port 26B.

Next, the content dispensing method by the metering dispenser 1 configured as described above will be described.
First, the consumer (user) screws the metering dispenser 1 into the mouth 3 of the container 2 so that the central axis O of the metering dispenser 1 is along the vertical direction as shown in FIG. The container 2 is held by the holder 40 while the container 2 is tilted.

  And a consumer pushes the outer member 13 with respect to the inner member 12, and makes it a filling position (refer FIG. 1). In the filling position, since the lower end of the first sliding cylinder portion 31 is located above the upper end of the communication port 26B of the cylindrical portion 26, the communication port 26B is opened. Therefore, the contents stored in the container 2 flow into the filling space 32A through the mounting cylinder portion 11 and the communication path 26A, and the air in the filling space 32A passes through the communication port 26B and communicates with the communication path 26A. Replaced by introduction. On the other hand, the second sliding cylinder portion 33 has an upper end located above the upper end of the flow port 28A and closes the flow port 28A. Therefore, the spout 13 </ b> A is closed by the plug body 22. Thereby, the content filled in the filling space 32A is not poured out of the metering dispenser 1 from the spout 13A. Therefore, the filling space 32A is filled with a certain amount of contents corresponding to the volume.

  Subsequently, the consumer holds the operation unit 32B and pulls it down along the central axis O. When the operation part 32B is pulled down, the first and second sliding cylinder parts 31 and 33 slide downward along the outer peripheral surfaces of the cylindrical part 26 and the cylindrical part 28, respectively. And the 1st sliding cylinder part 31 is located in the intermediate | middle position between a filling position and the extraction | pouring position below the communication port 26B of the communication part 21, and covers the communication port 26B. Thereby, the communication port 26 </ b> B is closed by the first sliding cylinder portion 31. On the other hand, the upper end of the second sliding cylinder portion 33 does not reach the upper end of the flow port 28A at this intermediate position, and covers the flow port 28A. For this reason, the spout 13 </ b> A is closed by the plug body 22.

  Then, the consumer further pulls down the operation portion 32B and positions the outer member 13 at the dispensing position (see FIG. 3). At this time, since the upper end of the second sliding cylinder portion 33 moves below the upper end of the flow port 28A, the flow port 28A is opened. For this reason, the spout 13A is opened and communicates with the filling space 32A through the circulation port 28A. As a result, the contents filled in the filling space 32 </ b> A are poured out of the metering dispenser 1 from the spout 13 </ b> A through the circulation port 28 </ b> A of the cylindrical body portion 28. On the other hand, the content in the container 2 is not filled in the filling space 32A because the first sliding cylinder portion 31 covers the communication port 26B.

In the pouring position, the second stop convex portion 31A is locked by the first stop convex portion 23A. Therefore, the outer member 13 is prevented from moving further downward along the central axis O from the dispensing position. Thereby, positioning of the outer member 13 in the extraction | pouring position is performed easily.
In this way, in the state where the filling space 32A is filled with the contents, the filling port 32A is further filled with the contents in the container 2 by opening the spout 13A after closing the communication port 26B first. The contents of the filling space 32A are poured out of the metering dispenser 1 while preventing the above. Thereby, a certain amount of contents are poured out.

  Thereafter, the consumer holds the operation unit 32B and pushes it up along the central axis O. When the operation portion 32B is pushed up, the second sliding cylinder portion 33 covers the circulation port 28A because the upper end moves upward from the upper end of the circulation port 28A. For this reason, the spout 13 </ b> A is blocked by the plug body 22. Thus, contrary to the above, by closing the spout 13A before opening the communication port 26B, the contents in the container 2 can be leaked to the outside through the metering dispenser 1. To prevent.

And a consumer pushes up operation part 32B further, and positions outside member 13 in a filling position. In the filling position, since the communication port 26B is opened as described above, the content in the container 2 is filled again into the filling space 32A. Thus, the movement of the outer member 13 along the central axis O is guided by the first and second sliding cylinder portions 31 and 33 that slide along the outer peripheral surface of the communication portion 21 or the plug body portion 22. Done stably.
Note that, at the filling position, the upper end of the first sliding cylinder portion 31 is abutted against the lower surface of the annular flat surface portion 25. Therefore, the outer member 13 is prevented from moving further upward along the central axis O from the filling position. Thereby, positioning of the outer member 13 in a filling position is performed easily.
As described above, a certain amount of contents are weighed and dispensed.

  According to the metering dispenser 1 having the above-described configuration, a predetermined amount of contents can be obtained simply by reciprocating the outer member 13 exposed to the outside along the central axis O without performing a complicated operation. Can weigh and dispense. Moreover, since the 1st and 2nd sliding cylinder parts 31 and 33 slide along the outer peripheral surface of the communication part 21 or the plug part 22, the reciprocation of the outer member 13 is stabilized. Further, the upper end of the first sliding cylinder portion 31 is positioned at the filling position, and the second stop convex portion 31A is locked at the dispensing position, so that the outer member 13 can be easily positioned at the filling position and the dispensing position. Yes. From the above, the operability of the metering dispenser 1 is improved.

  Next, 2nd Embodiment of the metering dispenser by this invention is described based on drawing. The embodiment described here has the same basic configuration as the first embodiment described above, and is obtained by adding another element to the first embodiment described above. Therefore, in FIG.4 and FIG.5, the same code | symbol is attached | subjected to the same component as FIGS. 1-3, and this description is abbreviate | omitted.

  As shown in FIG. 4, the metering dispenser 50 according to the second embodiment includes an inner member 51 and an outer member 52. A male screw portion 56 </ b> A is formed on the outer peripheral surface of the cylindrical portion 56 of the plug portion 55 of the inner member 51. The outer member 52 includes first and second sliding cylinder parts 31 and 32, a filling part 61 in which a filling space 61A is formed, a screw cylinder part 62, and a flange part 63.

An operation portion 64 for rotating the filling portion 61 around the central axis O is provided on the outer peripheral surface of the central portion of the filling portion 61.
The screw cylinder portion 62 has a substantially cylindrical shape along the central axis O, and a female screw portion 62 </ b> A that engages with the male screw portion 56 </ b> A is formed on the inner peripheral surface of the screw cylinder portion 62.
The flange portion 63 has a substantially disk shape in plan view, and connects the outer peripheral surface of the screw cylinder portion 62 and the inner peripheral surface of the central portion of the filling portion 61. The flange portion 63 is formed with a plurality of flow ports 63A at intervals in the circumferential direction. Therefore, the flow of the contents in the filling space 61 </ b> A is not hindered by the flange portion 63.
Further, the flange portion 63 and the screw cylinder portion 62 are integrally formed and are fitted to the filling portion 61 so as not to be relatively rotatable.

Next, a content dispensing method using the metering dispenser 50 configured as described above will be described.
First, the consumer screws the metering dispenser 50 into the mouth portion 3 of the container 2, holds the operation portion 64, rotates it appropriately around the central axis O, and moves the outer member 52 upward. The outer member 52 is positioned at the filling position (see FIG. 4). Thereby, the content accommodated in the container 2 is filled into the filling space 61A through the mounting cylinder portion 11 and the communication passage 26A.

Subsequently, the consumer holds the operation unit 64 and rotates it around the central axis O. At this time, the outer member 52 moves downward to the pouring position when the screw cylinder portion 62 screwed with the male screw portion 56A of the plug body portion 55 moves downward by rotation around the central axis O. (See FIG. 5). As a result, the contents filled in the filling space 61A are poured out of the metering dispenser 50 from the spout 51A through the flow port 28A of the cylindrical body portion 28.
As described above, a certain amount of contents are weighed and dispensed.

  The metering dispenser 50 configured as described above has the same effect as described above, but prevents the outer member 52 from moving along the central axis O due to the weight of the filling portion 61 filled with the contents. it can. Further, the outer member 52 can be easily rotated by the operation portion 64. Thereby, the operability is further improved.

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 cylinder portion is configured to be screwed into the mouth portion, but may be other configurations such as a configuration in which the mounting cylinder portion is fitted to the mouth portion.
The communication port is opened and closed by a cylindrical first sliding cylinder, but may be opened and closed by a member having another shape as long as it can be opened and closed.
And the communication path should just be a flow path which connects the inside of a mounting cylinder part, and a communicating port, and other shapes, such as groove shape, may be sufficient as it.
Further, the operation member may not be provided on the outer member, and the filling member may be directly operated to move the outer member up and down along the central axis or rotate around the central axis.

  Further, in the filling position, the upper end of the first sliding cylinder part is configured to abut against the lower surface of the annular flat part of the inner member. Good. Each of the inner member and the outer member has the first and second stop protrusions, but if the outer member can be positioned at the pouring position, the inner member and the outer member may not have the first and second stop protrusions. Good. Here, for example, the outer member and the inner member may be configured to snap-engage at the filling position and the dispensing position.

  Further, the outer member has the first and second sliding tube portions, but if the reciprocating movement of the outer member with respect to the inner member can be stably performed, one of the first and second sliding tube portions or It is not necessary to have both.
