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 each 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 (for example, see Patent Document 1). The metering dispenser includes an inner member and a hollow outer member that is externally fitted to the inner member so as to form a filling space between the inner member and the inner member. The inner member opens and closes a communicating portion formed with a communicating passage communicating with the inside of the mouth portion, a communicating portion communicating with the communicating passage and the filling space, and a spout formed in the outer member for pouring the contents of the filling space. A plug body portion.

And in this metering dispenser, the outer member is moved up and down with respect to the inner member, the communication port is opened and the filling port is closed, and the inside of the container is connected via the communication passage and the communication port of the inner member. And filling space. Thereby, the liquid in the container is filled in the filling space. Thereafter, the outer member is moved downward relative to the inner member, and the liquid in the filling space is poured out by setting the pouring position to close the communication port and open the pouring port. In this way, a certain amount of liquid is weighed and dispensed from the container.
Here, the outer member protrudes radially outward and engages with the inner member at the pouring position to position the outer member at the pouring position, and the outer member is detached from the inner member. An engaging protrusion for regulating is provided.

  However, even in such a metering dispenser, for example, in order to clean the outer member and the inner member, it is required to facilitate disassembly of the inner member and the outer member.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a metering dispenser with improved ease of disassembly of the inner member and the outer member.

  The present invention employs the following means in order to solve the above problems. That is, the metering dispenser of the present invention includes an inner member and a hollow outer member that is externally fitted to the inner member so as to be relatively movable and forms a filling space with the inner member. A metering dispenser attached to a mouth portion of a container that contains a communication passage in which the inner member communicates with the inside of the mouth portion and a communication port that communicates the communicating passage with the filling space. A plug body part that opens and closes a spout formed in the outer member that pours out the contents in the filling space, and an elastic piece part that elastically deforms radially inwardly. One of the member and the outer member reciprocates between a filling position that opens the communication port and closes the spout, and a pouring position that closes the communication port and opens the spout The elastic piece is movable, and at least a part of the elastic piece is the outer member. A second engaging portion that is disposed so as to be exposed and that protrudes radially outward and engages with a first engaging portion that is formed on the outer member, thereby restricting separation of the outer member from the inner member. It is characterized by having.

  In this invention, when the elastic piece portion is elastically deformed inward in the radial direction, the engagement between the first engagement portion and the second engagement portion is released, and even if the outer member is moved relative to the inner member, Since the first engaging portion and the second engaging portion are not engaged, the movement of the outer member relative to the inner member is not restricted at the position where the first engaging portion and the second engaging portion are engaged, and the outer member is It can be moved further. Thereby, the outer member can be relatively pulled out from the inner member. At this time, since at least a part of the elastic piece portion is exposed to the outside from the outer member, an operation of elastically deforming the elastic piece portion radially inward is easily performed. Therefore, the inner member and the outer member can be easily disassembled.

In the metering dispenser of the present invention, a pair of the elastic piece portions may be formed at intervals in the radial direction.
In this case, since both elastic piece portions can be easily elastically deformed radially inward by picking the pair of elastic piece portions, disassembly is further facilitated.

In the metering dispenser of the present invention, the second engaging portion may stop the outer member relative to the inner member in one of the filling position and the dispensing position. .
In this case, relative reciprocation between the inner member and the outer member is stably performed by stopping the outer member with respect to the inner member in one of the filling position and the dispensing position.

Moreover, the metering dispenser of the present invention may include a stop portion that stops the outer member relative to the inner member at the other of the filling position and the dispensing position.
In this case, the relative reciprocation between the inner member and the outer member is stably performed by stopping the outer member at the other of the filling position and the dispensing position with respect to the inner member.

Moreover, in the metering dispenser of the present invention, an intermediate position where the communication port and the pouring port are closed may be set between the filling position and the pouring position.
In this case, when the outer member is moved relative to the inner member from the filling position to the pouring position, the communication port is closed at the intermediate position, and the pouring port is opened after the pouring port is closed. By doing so, the content in the container is not filled into the filling space through the communication port when the spout is opened, 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, the outer member may have a sliding cylinder portion that slides relatively along the outer peripheral surface of the inner member.
In this case, since the outer member is guided by the sliding cylinder portion, the relative reciprocation of the outer member can be stably performed. Therefore, the operability of the metering dispenser is further improved.

  According to the metering dispenser of the present invention, the outer member can be pulled out from the inner member by elastically deforming the elastic piece portion inward in the radial direction and releasing the engagement. Is easy to disassemble.

  Hereinafter, 1st Embodiment of the metering dispenser in this invention is described based on drawing. In each drawing used in the following description, the scale is appropriately changed to make each member a recognizable size.

As shown in FIG. 1, the metering dispenser 1 in the present embodiment is detachably screwed into a mouth portion 3 provided in a container 2. In addition, the container 2 is a gable top, a blow bottle, a pouch, a bag in box etc., for example.
The metering dispenser 1 is made of, for example, a resin material such as PE (polyethylene) or PP (polypropylene), and moves to a cylindrical inner member 11 attached to the cylindrical mouth 3 and the inner member 11. A hollow outer member 12 that is externally fitted so as to form a filling space 12 </ b> A between the inner member 11 and the inner member 11.
The inner member 11 and the outer member 12 are disposed in a state in which their respective central axes are located on a common axis. Hereinafter, this common axis will be referred to as a central axis O, and in FIG. A direction perpendicular to the central axis O is referred to as a radial direction, and a direction around the central axis O is referred to as a circumferential direction.

The inner member 11 includes a mounting cylinder part 21, a communication part 22, a plug part 23, and a pair of elastic piece parts 24 that extend along the central axis O and are connected in order from the upper side.
The mounting cylinder portion 21 has a cylindrical shape and is detachably screwed into the mouth portion 3.
The communication part 22 has an annular part (stop part) 31 and a cylindrical part 32.
The annular part 31 extends radially inward from the lower end of the mounting cylinder part 21.

The cylindrical portion 32 extends downward from the inner edge of the annular portion 31 along the central axis O, and has a cylindrical trunk portion 33, a shoulder portion 34, and It has a cylindrical neck 35. The inner diameter and outer diameter of the shoulder portion 34 are gradually reduced toward the lower side.
Inside the cylindrical portion 32, a communication path 32 </ b> A is formed that communicates with the inside of the mouth portion 3 of the container 2 through the inside of the mounting cylinder portion 21, and a communication path is provided on the shoulder portion 34 and the neck portion 35 of the cylindrical portion 32. A plurality of communication ports 32B communicating 32A and the radially outer side of the communication portion 22 are formed at intervals in the circumferential direction.

The plug portion 23 extends downward from the lower end of the cylindrical portion 32 along the central axis O, and includes a top plate portion 36, a bottom plate portion 37 disposed below the top plate portion 36, and the top plate portion 36. And a main body portion 38 to which the bottom plate portion 37 is connected.
The top plate portion 36 has a disk shape that bulges up and down as it goes radially inward.
The bottom plate portion 37 has a conical bowl shape that gradually increases in diameter as the outer diameter and inner diameter decrease downward and opens downward.
The main body 38 has a cross shape in a cross section perpendicular to the central axis O. The main body 38 may have a solid structure such as a columnar shape.

The pair of elastic pieces 24 are band-like members extending downward from the radial center of the bottom plate 37 and are formed so as to face each other in the radial direction with the central axis O interposed therebetween. The elastic piece 24 is elastically deformed radially inward by applying a force inward in the radial direction.
At the lower end portion of the elastic piece portion 24, an engagement protrusion portion (second engagement portion) 24A that protrudes outward in the radial direction is formed. The engagement protrusion 24A protrudes radially outward from a second small diameter portion (first engagement portion) 56 in a second sliding cylinder portion (sliding cylinder portion) 43, which will be described later, of the outer member 12. The second small diameter portion 56 is in contact with the lower end. The elastic piece 24 is surrounded by the second sliding cylinder 43 from the outside in the radial direction. Note that the lower end of the elastic piece 24 is formed when the upper end of a later-described first sliding cylinder (sliding cylinder) 41 of the outer member 12 abuts on the annular portion 31, as shown in FIG. The outer member 12 is exposed from the lower end of the second sliding cylinder portion 43.

The outer member 12 is externally fitted to the cylindrical portion 32, the top plate portion 36, and the bottom plate portion 37, and includes a first sliding cylinder portion 41, a filling portion 42, and a first portion that are continuously provided along the central axis O from the upper side. Two sliding cylinders 43 are provided.
The 1st sliding cylinder part 41 has comprised the cylindrical shape extended along the central axis O, the 1st large diameter part 51 and the 1st continuous cylinder part (stop part) 52 which were continuously arranged from the upper side in order. And a first small-diameter portion 53.
The first large-diameter portion 51 is disposed on the outer peripheral surface of the cylindrical portion 32, and the inner diameter is equal to the outer diameter of the body portion 33 in the cylindrical portion 32. Therefore, the first large diameter portion 51 is in sliding contact with the outer peripheral surface of the cylindrical portion 32. The vertical length of the first large diameter portion 51 is equal to the vertical length of the body portion 33.

The inner diameter and the outer diameter of the first continuous cylinder portion 52 are gradually reduced toward the lower side, and the inner diameter of the first continuous cylinder portion 52 is equal to the outer diameter of the shoulder portion 34. Further, the vertical length of the first continuous cylinder portion 52 is equal to the vertical length of the shoulder portion 34.
The inner diameter of the first small diameter portion 53 is equal to the outer diameter of the neck portion 35 and the top plate portion 36. Therefore, the neck portion 35 is slidable in the vertical direction on the inner peripheral surface of the first small diameter portion 53.
The first continuous cylinder portion 52 and the first small diameter portion 53 move in the vertical direction to cover the communication port 32B from the radially outer side, and the top plate portion 36 is in sliding contact with the inner peripheral surface of the first small diameter portion 53. Thus, the communication port 32B is closed.

The filling portion 42 has a hollow, substantially oval shape extending along the central axis O, and an intermediate portion in the vertical direction bulges radially outward from both upper and lower end portions. In addition, a filling space 12A that communicates with the communication passage 32A through the communication port 32B is formed inside the filling portion 42. The filling part 42 has an upper end connected to the lower end of the first sliding cylinder part 41 and a lower end connected to the upper end of the second sliding cylinder part 43. In addition, a spout 42 </ b> A that connects the filling space 12 </ b> A and the outside of the outer member 12 through the inside of the second sliding cylinder portion 43 is formed at the lower end of the filling portion 42. Further, on the outer peripheral surface of the central portion of the filling portion 42, an operation portion 42B protruding outward in the radial direction is formed over the entire circumference.
The filling portion 42 is formed by fitting upper and lower members 54 and 55 that are divided into two parts in the vertical direction around the center in the vertical direction. Here, the upper member 54 is formed integrally with the first sliding tube portion 41, and the lower member 55 is formed integrally with the second sliding tube portion 43.

Similar to the first sliding cylinder part 41, the second sliding cylinder part 43 is arranged on the outer surface of the bottom plate part 37 and the pair of elastic piece parts 24, and is continuously provided along the central axis O from the upper side. The second small-diameter portion 56, the second continuous cylinder portion 57, and the second large-diameter portion 58 are provided.
The inner diameter of the second small diameter portion 56 is equal to the outer diameter of the bottom plate portion 37. Therefore, the bottom plate portion 37 is slidable in the vertical direction on the inner peripheral surface of the second small diameter portion 56. In the state where the engagement protrusion 24A is in contact with the lower end of the second small diameter portion 56, the vertical distance between the lower end of the second small diameter portion 56 and the peripheral edge of the bottom plate portion 37 is the first small diameter portion. The distance in the vertical direction between the upper end of 53 and the peripheral edge of the top plate portion 36 is the same.
The inner diameter and the outer diameter of the second continuous cylinder portion 57 are gradually enlarged toward the lower side.

  As described above, the outer member 12 includes the filling position where the engagement protrusion 24A contacts the lower end of the second small diameter portion 56 and the upper end of the first large diameter portion 51 of the first sliding cylinder portion 41 at the annular portion 31. It is possible to reciprocate in the up-down direction between the pouring position where it hits. Then, as the first and second small diameter portions 53 and 56 move from the filling position to the pouring position, the spout 42A is filled almost simultaneously with the top plate portion 36 slidingly contacting the inside of the first small diameter portion 53. When the bottom plate portion 37 is in sliding contact with the inner side of the second small diameter portion 56 when the space 12A is opened and moved from the pouring position to the filling position, the communication port 32B is opened to the filling space 12A almost simultaneously. . Therefore, when the first and second small diameter portions 53 and 56 move in the vertical direction, the top plate portion 36 or the bottom plate portion 37 is in sliding contact with either one of the inside and the communication port 32B and the spout port 42A. Are not released at the same time.

Next, the content dispensing method by the metering dispenser 1 configured as described above will be described.
First, the metering dispenser 1 is attached to the mouth 3 of the container 2. Then, as shown in FIG. 1, the outer member 12 is drawn downward with respect to the inner member 11 to be a filling position. In the filling position, the shoulder portion 34 and neck portion 35 of the cylindrical portion 32 and the top plate portion 36 of the plug body portion 23 are disposed radially inward of the first large diameter portion 51 of the first sliding cylinder portion 41. Therefore, the communication port 32B is opened to the filling space 12A, and the inside of the container 2 communicates with the filling space 12A. Therefore, the contents stored in the container 2 flow into the filling space 12A through the inside of the first sliding cylinder portion 41 through the communication path 32A, and the air in the filling space 12A is communicated with the communication port. It is introduced and replaced with the communication path 32A through 32B. On the other hand, since the bottom plate part 37 of the plug part 23 is in sliding contact with the inside of the second small diameter part 56, the spout 42 </ b> A is closed by the plug part 23. Thereby, the contents filled in the filling space 12A are not poured out of the metering dispenser 1 from the spout 42A. Therefore, the filling space 12A is filled with a certain amount of contents corresponding to the volume.

At this time, the outer member 12 is filled by the sliding resistance between the first and second sliding tube portions 41 and 43 and the inner member 11, and the engagement between the engagement protrusion 24A and the lower end of the second small diameter portion 56. Although it is held at the position, it may be configured to be held by an engagement method other than the sliding resistance (for example, undercut fitting).
Note that, in the filling position, the engagement protrusion 24 </ b> A is in contact with the lower end of the second small diameter portion 56. Therefore, the outer member 12 is prevented from moving further downward from the filling position. Thereby, the outer member 12 is positioned at the filling position.

  Next, for example, when the operation member 42B is held and the outer member 12 is pushed upward, the first large-diameter portion 51 of the first sliding tube portion 41 moves upward along the outer peripheral surface of the body portion 33 of the cylindrical portion 32. The second small-diameter portion 56 of the second sliding cylinder portion 43 slides upward along the outer surface of the bottom plate portion 37. The bottom plate portion 37 is positioned below the lower end of the second small-diameter portion 56 almost simultaneously with the sliding contact of the top plate portion 36 inside the first small-diameter portion 53 of the first sliding cylinder portion 41. Therefore, almost simultaneously with the closing of the communication port 32B, the spout 42A is opened to the outside of the metering dispenser 1.

Then, as shown in FIG. 2, the outer member 12 is further pushed in and positioned at the dispensing position. Thereby, the filling space 12A communicates with the outside of the metering dispenser 1, and the contents filled in the filling space 12A are poured out of the metering dispenser 1 from the spout 42A. On the other hand, since the communication port 32B is closed, the content in the container 2 is not filled into the filling space 12A.
In this way, in the state where the filling space 12A is filled with the contents, the contents in the container 2 are transferred to the filling space 12A by preventing the communication port 32B and the spout 42A from being simultaneously opened. Further, the contents of the filling space 12A are poured out of the metering dispenser 1 while preventing filling. Thereby, a certain amount of contents are poured out.

  Thereafter, for example, when the operation member 42B is held and pulled down, and the outer member 12 is moved downward with respect to the inner member 11, the bottom plate portion 37 almost slidably contacts the inner side of the second small-diameter portion 56 almost simultaneously. 36 is located above the upper end of the first small diameter portion 53. This prevents the contents in the container 2 from leaking outside through the metering dispenser 1.

Then, the outer member 12 is moved further downward with respect to the inner member 11, and the outer member 12 is positioned again at the filling position as shown in FIG. At the filling position, the communication port 32B is opened to the filling space 12A as described above, so that the contents in the container 2 are filled again into the filling space 12A. As described above, the reciprocating movement of the outer member 12 is guided by the first and second sliding cylinder portions 41 and 43 that slide along the outer peripheral surface of the communication portion 22 or the plug body portion 23. Done.
Note that, in the filling position, the engagement protrusion 24 </ b> A is in contact with the lower end of the second small diameter portion 56. Therefore, the outer member 12 is prevented from moving further downward from the filling position. Thereby, the outer member 12 is positioned at the filling position.
As described above, a certain amount of contents are weighed and dispensed.

Next, a method for disassembling the inner member 11 and the outer member 12 will be described.
First, with the outer member 12 positioned at the pouring position, as shown by an arrow A1 in FIG. 3, the pair of elastic pieces 24 exposed from the lower end of the outer member 12 are picked and elastically inward in the radial direction. Deform. As a result, the engagement between the engagement protrusion 24A of the elastic piece portion 24 and the lower end of the second small diameter portion 56 of the second sliding cylinder portion 43 is released. Then, the outer member 12 is pulled down with respect to the inner member 11, and the outer member 12 is pulled out from the inner member 11.
The outer member 12 is removed from the inner member 11 as described above. In addition, although the internal diameter of the 1st small diameter part 53 is equivalent to the internal diameter of the 2nd small diameter part 56, it is good also as more than the distance between the radial direction outer ends of a pair of engagement protrusion part 24A. Thereby, even if the elastic piece portion 24 is restored and deformed, the outer member 12 can be more easily pulled out from the inner member 11 without hooking the engaging protrusion 24 </ b> A to the lower end of the first small diameter portion 53.

According to the metering dispenser 1 configured as described above, the pair of elastic pieces 24 are elastically deformed radially inward to disengage the lower end of the second small-diameter portion 56 from the engagement protrusion 24A. By doing so, the outer member 12 can be pulled out from the inner member 11. Further, by pinching the pair of elastic pieces 24, these elastic pieces 24 can be elastically deformed radially inward. As described above, the inner member 11 and the outer member 12 can be easily disassembled.
Further, the first and second sliding cylinder portions 41 and 43 slide along the outer peripheral surface of the communication portion 22 and the outer peripheral surface of the plug body portion 23, and the outer member 12 is positioned at the filling position and the dispensing position. Therefore, the reciprocating movement of the outer member 12 is stabilized.

  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 FIGS. 4 to 8, the same components as those in FIGS. 1 to 3 are denoted by the same reference numerals, and the description thereof is omitted.

In the metering dispenser 100 in the present embodiment, as shown in FIG. 4, the state where the outer member 102 is pushed into the inner member 101 is the filling position, and as shown in FIG. The state where the outer member 102 is pulled out is the pouring position.
As shown in FIGS. 4 and 5, the inner member 101 includes a mounting cylinder part 21, a communication part 111, a plug part 112, and a pair of elastic piece parts 113 that are continuously provided from the upper side.
The communication part 111 has an annular part 31 and a cylindrical part 114. A cylindrical fitting tube portion 31 </ b> A that sandwiches the mouth portion 3 together with the mounting tube portion 21 is formed on the annular portion 31 so as to protrude upward in the radial direction from the mounting tube portion 21. In addition, the inner diameter and the outer diameter of the cylindrical portion 114 are substantially constant in the vertical direction, and the lower end of the cylindrical portion 114 has a communication port 114B that communicates the communication passage 114A and the outer radial direction of the communication portion 111. A plurality are formed at intervals in the direction.

The plug body 112 includes a top plate portion 115, a top cylindrical bottom tube portion 116 disposed below the top plate portion 115, and a plate shape connecting the top plate portion 115 and the bottom tube portion 116. A main body 117.
The main body 117 has a cross-shaped cross section in a direction perpendicular to the central axis O. The main body 117 may have a solid structure such as a columnar shape.

The pair of elastic piece portions 113 are band-like members extending downward from the lower end of the bottom cylinder portion 116 and are formed to face each other in the radial direction with the central axis O interposed therebetween. In addition, a circulation port 113A is formed between the pair of elastic piece portions 113 in the circumferential direction.
The elastic piece portion 113 is formed with an engaging protrusion (second engaging portion) 113B that protrudes outward in the radial direction. The engagement protrusion 113B is a second slide of the outer member 102, which will be described later, when the upper end of a first slide cylinder (slide cylinder) 121, which will be described later, of the outer member 102 abuts the annular portion 31. The tube portion (sliding tube portion) 123 is surrounded from the outside in the radial direction. In addition, the lower end part of the elastic piece part 113 is exposed from the lower end of the said 2nd sliding cylinder part 123 of an outer side member.

The outer member 102 is externally fitted to the cylindrical portion 114, the bottom cylindrical portion 116, and the pair of elastic piece portions 113, and the first sliding cylindrical portion 121, the filling portion 122, and the second sliding that are continuously provided from the upper side. A cylindrical portion 123 is provided.
The first sliding cylinder portion 121 has an inner diameter and an outer diameter that are substantially constant over the entire length in the vertical direction, and is in sliding contact with the outer peripheral surface of the cylindrical portion 114.
The length of the first sliding cylinder 121 in the vertical direction is equal to the length of the cylindrical part 114 in the vertical direction, and is longer than the vertical length of the communication port 114B. That is, the 1st sliding cylinder part 121 obstruct | occludes the communicating port 114B by moving to an up-down direction and covering the communicating port 114B from radial direction outer side.

The filling portion 122 is formed by fitting the upper and lower members 124 and 125 together. A spout 122A is formed at the lower end of the filling portion 122.
The second sliding cylinder 123 has an inner diameter and an outer diameter that are substantially constant over the entire length in the vertical direction, and is disposed on the outer peripheral surface of the bottom cylinder portion 116 of the plug body 112 and the outer surfaces of the pair of elastic pieces 113. Yes. Further, the inner diameter of the second sliding cylinder portion 123 is equal to the outer diameter of the bottom cylinder portion 116. Therefore, the second sliding cylinder portion 123 is in sliding contact with the outer peripheral surface of the bottom cylinder portion 116 and the outer surfaces of the pair of elastic piece portions 113. Further, on the inner peripheral surface of the second sliding cylinder portion 123, a pair of guide groove portions (first engagement portions) that receive the engagement protrusions 113 </ b> B and restrict the movement of the pair of elastic piece portions 113 in the circumferential direction. ) 123A is formed at intervals in the circumferential direction.

  The guide groove portion 123 </ b> A extends in the vertical direction from the lower end of the second sliding cylinder portion 123, and is engaged with the engagement protrusion 113 </ b> B at the upper end as the outer member 102 moves. The vertical length of the guide groove 123A is such that when the engagement protrusion 113B engages with the upper end of the guide groove 123A, the first sliding cylinder 121 is closed and the second sliding cylinder 123 is closed. Is such a length as to open the spout 122A. The circumferential size of the guide groove 123A is preferably equal to the circumferential size of the engaging protrusion 113B.

  As described above, the outer member 102 is locked by the filling position where the upper end of the first sliding cylinder portion 121 abuts the lower surface of the annular portion 31, and the upper end of the guide groove portion 123A by the engaging protrusion 113B of the elastic piece portion 113. It is possible to reciprocate up and down between the pouring position. And if the 1st and 2nd sliding cylinder parts 121 and 123 move to an up-down direction, the communicating port 114B and the circulation port 113A will not be simultaneously open | released with respect to the filling space 102A. Furthermore, when the first and second sliding cylinders 121 and 123 move from the filling position to the pouring position, the circulation port 113A is not opened to the filling space 102A until the communication port 114B is closed.

Next, a content dispensing method using the metering dispenser 100 configured as described above will be described.
First, as shown in FIG. 4, the outer member 102 is pushed upward with respect to the inner member 101 to obtain a filling position. In the filling position, since the lower end of the first sliding cylinder 121 is located above the upper end of the communication port 114B of the cylindrical portion 114, the communication port 114B is open to the filling space 102A. Therefore, the content accommodated in the container 2 is filled in the filling space 102A. On the other hand, since the upper end of the second sliding cylinder portion 123 is located above the upper end of the circulation port 113A, the second sliding cylinder portion 123 covers (closes) the circulation port 113A. Therefore, the spout 122A is closed by the plug body 112. Thereby, the content filled in the filling space 102A is not poured out of the metering dispenser 100 from the spout 122A.

  Next, when the outer member 102 is pulled down, the first and second sliding cylinder portions 121 and 123 are lowered along the outer peripheral surface of the cylindrical portion 114 and the plug body portion 112 and the outer surface of the pair of elastic piece portions 113, respectively. To slide. And the 1st sliding cylinder part 121 is located in the intermediate | middle position between a filling position and the extraction | pouring position below a communication port 114B of the communication part 111, and covers the communication port 114B. Thereby, the communication port 114 </ b> B is closed by the first sliding cylinder portion 121. On the other hand, the upper end of the second sliding cylinder portion 123 does not reach the upper end of the flow port 113A at this intermediate position, and still covers the flow port 113A. For this reason, the spout 122 </ b> A is closed by the plug body 112.

Then, as shown in FIG. 7, when the outer member 102 is further pulled down and positioned at the pouring position, the second sliding cylinder portion 123 opens the circulation port 113A. For this reason, the spout 122A is opened to the filling space 102A, and the content filled in the filling space 102A is poured out of the metering dispenser 100 from the spout 122A. On the other hand, the contents in the container 2 are not filled into the filling space 102A because the first sliding cylinder 121 covers the communication port 114B. As a result, a certain amount of content is dispensed.
Note that, in the pouring position, the engagement protrusion 113B of the elastic piece 113 is engaged with the upper end of the guide groove 123A. Therefore, the outer member 102 is positioned at the dispensing position.

Thereafter, the outer member 102 is pushed upward, and after passing through the intermediate position, the outer member 102 is positioned again at the filling position as shown in FIG. At the filling position, the content in the container 2 is filled again into the filling space 102A as described above.
In the filling position, the upper end of the first sliding cylinder 121 is abutted against the lower surface of the annular portion 31. Thereby, the outer member 102 is positioned at the filling position.
As described above, a certain amount of contents are weighed and dispensed.

Here, the guide groove 123A has a linear shape extending in the vertical direction, but may be a guide groove 123A ′ having an L shape when viewed from the radial direction, for example, as shown in FIG. The circumferential width of the guide groove 123A ′ is equal to the circumferential width of the engagement protrusion 113B, and an engagement groove 123B ′ extending in the circumferential direction is formed at the lower end of the guide groove 123A ′. Has been.
The engaging protrusion 113B is engaged with the engaging groove 123B ′ by rotating in the circumferential direction with respect to the inner member 101 when the outer member 102 ′ is in the filling position. At this time, the outer member 102 ′ moves in the vertical direction when the engagement protrusion 113 B is locked to the engagement groove 123 B ′ and the upper end of the first sliding cylinder 121 abuts against the lower surface of the annular portion 31. Is regulated.
When the outer member 102 ′ is moved from the filling position to the dispensing position, the outer member 102 ′ is rotated in the circumferential direction to disengage the engaging protrusion 113B from the engaging groove 123B ′. As a result, the outer member 102 ′ can move in the vertical direction along the guide groove 123A ′. In this case, even if the upper end of the first sliding cylinder 121 is not in contact with the lower surface of the annular portion 31, the filling position can be accurately set.

Next, a method for disassembling the inner member 101 and the outer member 102 will be described.
First, in a state where the outer member 102 is positioned at the filling position, as shown by an arrow A2 in FIG. 5 and an arrow A3 in FIG. 6, the pair of elastic pieces 113 are picked and elastically deformed radially inward. Thereby, the engagement protrusion 113B of the elastic piece 113 and the guide groove 123A of the second sliding cylinder 123 are disengaged. Then, as shown by an arrow A4 in FIG. 6, the outer member 102 is rotated in the circumferential direction with respect to the inner member 101, and the circumferential positions of the engagement protrusion 113B and the guide groove 123A are shifted. Further, the knobs of the pair of elastic pieces 113 are released to restore the elastic pieces 113 to their original state.
At this time, since the circumferential positions of the engagement protrusion 113B and the guide groove 123A are shifted, the engagement protrusion 113B is not accommodated in the guide groove 123A even if the elastic piece 113 is restored and deformed.

When the outer member 102 is pulled down in this state, even if the outer member 102 reaches the pouring position, the engaging protrusion 113B is not locked to the upper end of the guide groove 123A, so that the outer member 102 moves at the pouring position. It moves further down without being stopped. Thereafter, the outer member 102 is pulled out from the inner member 101 and removed from the inner member 101.
The outer member 102 is removed from the inner member 101 as described above.
At this time, it is preferable to set the inner diameter of the first sliding cylinder 121 to be equal to or larger than the outer diameter of the engaging protrusion 113B.

  The metering dispenser 100 configured as described above has the same operations and effects as described above, but since the intermediate position is set, a certain amount of dispensing according to the volume of the filling space 102A is more reliable. To be done. In addition, even when the pair of elastic pieces 113 is released by rotating the outer member 102 in the circumferential direction with the pair of elastic pieces 113 picked, the engagement protrusion 113B engages with the guide groove 123A. Since this can be prevented, disassembly of the inner member 101 and the outer member 102 is further facilitated.

The fitting tube portion 222A and the first and second sliding tube portions 222 and 224 are configured such that when the inner member 201 moves in the vertical direction, the communication port 212B and the flow port 218A are simultaneously turned into the filling space 202A. Do not open it. Furthermore, when the inner member 201 moves from the filling position to the dispensing position, the fitting cylinder part 222A and the first and second sliding cylinder parts 222, 224 are connected to the circulation port 218A until the communication port 212B is closed. Do not open.

Next, a content dispensing method using the metering dispenser 200 configured as described above will be described.
First, as shown in FIG. 9, the inner member 201 is pulled down with respect to the outer member 202 to obtain a filling position. In the filling position, since the lower end of the first sliding cylinder portion 222 is located above the lower end of the communication port 212B, the communication port 212B is open to the filling space 202A. Therefore, the content stored in the container 2 is filled into the filling space 202A. On the other hand, since the upper end of the second sliding cylinder portion 224 is located above the upper end of the circulation port 218A, the second sliding cylinder portion 224 closes the circulation port 218A. Therefore, the spout 223 </ b> A is closed by the plug body 213. Thereby, the contents filled in the filling space 202A are not poured out of the metering dispenser 200 from the spout 223A.

For this reason, the spout 223A is closed.

Then, as shown in FIG. 10, when the inner member 201 is pushed further upward and positioned at the pouring position, the upper end of the circulation port 218 </ b> A exceeds the upper end of the second sliding cylinder part 224. For this reason, the spout 223A is opened, and the outside of the metering dispenser 200 and the filling space 202A communicate with each other through the inside of the lower cylinder portion 218. As a result, the contents filled in the filling space 202A are poured out of the metering dispenser 200 through the spout 223A. On the other hand, the contents in the container 2 are not filled in the filling space 202A because the communication port 212B is closed. As a result, a certain amount of content is dispensed.
In the pouring position, the connecting portion of the upper tube portion 216 and the intermediate tube portion 217 abuts on the lower end of the first slide tube portion 222, and the operation piece portion 218B is on the lower end of the second slide tube portion 224. Abut. Therefore, the inner member 201 is positioned at the dispensing position.

Thereafter, the inner member 201 is pulled down, and after passing through the intermediate position, the inner member 201 is positioned again at the filling position as shown in FIG. At the filling position, the content in the container 2 is filled again into the filling space 202A as described above.
Note that, at the filling position, the engagement protrusion 211A of the elastic piece 211 comes into contact with the upper end of the fitting cylinder 222A. Thereby, the inner member 201 is positioned at the filling position.
As described above, a certain amount of contents are weighed and dispensed.

Next, a method for disassembling the inner member 201 and the outer member 202 will be described.
First, the metering dispenser 200 is removed from the mouth 3 of the container 2 by releasing the screwing between the mounting cylinder 221 of the outer member 202 and the mouth 3 of the container 2. Then, as indicated by an arrow A5 in FIG. 11, the pair of elastic pieces 211 are picked and elastically deformed radially inward. As a result, the engagement between the engagement protruding portion 211A of the elastic piece portion 211 and the fitting cylindrical portion 222A is released. Then, the inner member 201 is pushed downward with respect to the outer member 202.
The inner member 201 is removed from the outer member 202 as described above.

  The metering dispenser 200 configured as described above also provides the same operations and effects as described above.

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. Moreover, although the inner member or the outer member has a mounting cylinder portion mounted on the mouth portion, the inner member or the outer member may be attached to the mouth portion using another mounting member.
Although a pair of elastic pieces are provided, it is sufficient that one or more elastic pieces are provided.
For example, in the first embodiment, the inner member and the outer member are relatively positioned at the pouring position by the upper end of the first sliding cylinder portion abutting against the lower surface of the annular portion. Other configurations such as snap-engagement may be used, and a configuration in which positioning is not performed may be used as long as reciprocation between the filling position and the pouring position is possible.
Although the intermediate position is set between the filling position and the dispensing position, the intermediate position need not be set.
The communication path may be a flow path that connects the inside of the mounting cylinder and the communication port, and may have another shape such as a groove shape.
The outer member has the first and second sliding cylinder portions. If the outer member can be stably reciprocated with respect to the inner member, one or both of the first and second sliding cylinder portions can be used. It may not have.
