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 cylindrical outer member that is attached to the mouth portion of the container main body in which the contents are accommodated and the inside communicates with the container main body, and is inserted into the outer member so as to be movable in the axial direction of the outer member. An inner member having a content extraction hole formed therein, and a content measuring space is formed between the outer member and the inner member, and the inner member is moved in the axial direction with respect to the outer member. In addition, there has been proposed a metering dispenser in which the contents weighed in the metering space are dispensed from the dispensing hole (see, for example, Patent Document 1).

JP2013-095460A

  However, in such a metering dispenser, there is a problem that it takes time to pour out the contents because pulsation of the contents occurs when dispensing the weighed contents.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide a metering dispenser capable of smoothly dispensing the weighed contents.

The present invention employs the following means in order to solve the above problems. That is, the metering dispenser of the present invention is attached to the mouth of the container main body that contains the contents, and has a cylindrical outer member that communicates with the container main body, and the outer member in the outer member. A cylindrical inner member that is movably inserted in the axial direction of the member and is formed with an outlet hole for the content, and the content is measured between the outer member and the inner member space is formed, the outside member, the introduced content in the container body into the metering space, and the introduction hole into which the inner member is removably fitted is formed, the inner member, the than the supply hole and before Symbol supply hole for guiding the contents of the metering space into the watch Deana formed on the axially inner and forms an air intake holes for introducing air into the metering space from said inner member It has a pouring cylinder portion that is, the pouring cylinder part, the inner member and the outer portion Wherein when the axis direction and outward to move the is detached from the introduction hole, and having a closing portion for closing the supply hole and the air intake hole against.

In this invention, when the contents filled in the measuring space are poured out, the contents are poured out from the pouring hole and outside air is introduced from the inner member into the measuring space through the pouring hole. Therefore, the pulsation at the time of dispensing is suppressed. That is, when the inner member is moved axially outward with respect to the outer member, the introduction hole is opened and the supply hole and the air intake hole are closed. In this state, the contents in the container body flow into the measurement space through the introduction hole. When the inner member is moved inward in the axial direction with respect to the outer member, the supply hole and the air intake hole are opened and the introduction hole is closed. In this state, the contents in the measurement space flow into the inner member through the supply hole and are discharged through the extraction hole. At the same time, external air is introduced into the metering space through the extraction hole and the air intake hole, replacing the metering space with air.
Thus, since the contents in the measurement space can be smoothly poured out, it is possible to shorten the time taken to pour out all the contents in the measurement space.

In the metering dispenser of the present invention, the outer member and the inner member may have the inner member detached from the introduction hole and the closing portion may block the supply hole and the air intake hole. Locking portions that lock each other may be formed.
In this case, when the introduction hole is opened and the supply hole and the air intake hole are closed, the inner member is restricted from moving further outward in the axial direction with respect to the outer member. The relative axial positions of the inner member and the outer member, which can supply the contents inside, can be easily and accurately adjusted without adjustment.

In the metering dispenser of the present invention, the pouring hole is formed at an end portion on the axially outer side of the inner member, and the engaging portion is locked to the end portion of the inner member. A lid body that is detached from the end when pulled outward in the axial direction in the state of being attached may be detachably mounted.
In this case, the pouring hole can be opened only when the contents are poured out. For example, dust and other foreign matters can be prevented from adhering to the pouring hole, thereby facilitating the hygiene of the pouring hole. Can be kept in. In addition, when the lid is pulled and the latching part of the inner member and the latching part of the outer member are latched with each other, the lid body is detached from the inner member, and the inner member is brought into contact with the outer member without touching the inner member. Since it can be moved in the axial direction, the contents can be prevented from adhering to the hand.

  According to the metering dispenser of the present invention, when the contents in the metering space are poured out, external air is introduced into the metering space through the pouring hole and the air intake hole. The pulsation at the time of departure can be suppressed, and the time taken to pour out all the contents in the measurement space can be shortened.

In addition, a first locking projection (engaging portion) 22A that protrudes radially inward is formed on the lower end of the first sliding cylinder portion 22 over the entire circumference. Furthermore, a fitting cylinder portion 26 is provided at the lower end of the first sliding cylinder portion 22 so as to protrude downward. The fitting tube portion 26 is disposed radially inward of the mounting tube portion 21 and sandwiches the mouth portion 3 in the radial direction between the fitting tube portion 21 and the mounting tube portion 21.

The measuring unit 23 has a middle portion in the vertical direction that bulges radially outward from both upper and lower ends, and a measuring space 27 is defined between the measuring unit 23 and the inner member 12. In addition, an introduction hole 23 </ b> A for introducing the contents in the container body 2 into the measurement space 27 is formed at the upper end of the measurement unit 23. The measuring portion 23 is formed by fitting the lower and upper members 28 and 29 which are divided into two parts up and down around the center in the up and down direction. Here, the lower member 28 is formed integrally with the mounting cylinder part 21 and the first sliding cylinder part 22, and the upper member 29 is formed integrally with the second sliding cylinder part 24.
The second sliding cylinder portion 24 extends upward from the upper end of the upper member 29 of the measuring portion 23.

  An intermediate portion in the vertical direction of the closing part 25 is fitted inside the second sliding cylinder part 24, and an upper end part of the closing part 25 protrudes upward from the second sliding cylinder part 24. In addition, a plurality (for example, two) of communication holes 25 </ b> A that open to the measurement space 27 are formed in the closed portion 25 below the second sliding cylinder portion 24 at intervals in the circumferential direction. At the upper end portion of the closing portion 25, a flange portion 25B that is locked to the upper end of the second sliding cylinder portion 24 is provided so as to protrude outward in the radial direction over the entire circumference.

The inner member 12 includes a pair of locking piece portions 31 that are arranged in order from the lower side along the central axis O, and a bottomed cylindrical extraction tube portion 32.
The locking piece portion 31 is a belt-like member extending downward from the lower end of the dispensing cylinder portion 32 and is disposed so as to face in the radial direction with the central axis O interposed therebetween. At the lower end of the locking piece 31, a second locking protrusion (locking portion) 31 </ b> A that can be locked with the first locking protrusion 22 </ b> A protrudes radially outward.

  The upper end opening of the dispensing cylinder portion 32 is a content dispensing hole 12A, and the dispensing cylinder portion 32 allows the contents in the measuring space 27 to pass through the inside of the dispensing cylinder portion 32. A plurality of (for example, two) supply holes 32A leading to 12A and air intake holes 32B formed below the supply holes 32A are formed at intervals in the circumferential direction. The supply hole 32A is aligned with the communication hole 25A of the closing part 25, and the measurement space 27 and the inside of the extraction cylinder part 32 communicate with each other through the supply hole 32A and the communication hole 25A. The air intake hole 32 </ b> B is formed in a portion below the lower end of the closing portion 25 and is open to the measurement space 27. Furthermore, an annular operation piece 32C is projected from the upper end portion of the dispensing tube portion 32 toward the outside in the radial direction in a plan view.

The lid body 13 includes a circular bottom wall portion 41 in a plan view and a cylindrical peripheral wall portion 42 extending upward from the outer peripheral edge of the bottom wall portion 41.
The bottom wall portion 41 has a radially central portion that bulges upward from the peripheral edge portion, is externally fitted to the upper end portion of the extraction tube portion 32, and closes the extraction hole 12A. The fitting strength of the lid 13 with respect to the inner member 12 is set to be lower than the locking strength of the first and second locking protrusions 22A and 31A. Further, the peripheral edge portion of the bottom wall portion 41 is in contact with the operation piece portion 32C.

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 body 2. Then, the lid 13 is pulled up as shown in FIG. When the lid 13 is pulled up, the inner member 12 is lifted upward together with the lid 13, and the second locking projection 31 </ b> A of the locking piece 31 is the first locking of the first sliding cylinder 22. The projection 22A is locked from below. Thereby, the introduction hole 23 </ b> A is opened, and the supply hole 32 </ b> A and the air intake hole 32 </ b> B of the extraction cylinder part 32 are closed by the closing part 25.
When the lid 13 is further pulled up in this state, the lid 13 is removed from the inner member 12 and the extraction hole 12A is opened. At this time, since the first and second locking protrusions 22A and 31A are locked to each other, further rising of the inner member 12 relative to the outer member 11 is restricted.

  Subsequently, as shown in FIG. 3, the container main body 2 equipped with the metering dispenser 1 is tilted to be in an inverted posture. When the container body 2 is tilted, the contents in the container body 2 flow into the measurement space 27 through the introduction hole 23A. Since the supply hole 32 </ b> A and the air intake hole 32 </ b> B are closed, the content flowing into the measurement space 27 does not flow into the dispensing cylinder portion 32, and a certain amount of content enters the measurement space 27. Filled.

Then, as shown in FIG. 4, for example, the inner piece 12 is pushed into the outer member 11 by pushing the operation piece 32 </ b> C along the central axis O. When the inner member 12 is pushed in, the supply hole 32A and the air intake hole 32B are opened, and the introduction hole 23A is closed. At this time, the operation piece portion 32C comes into contact with the upper end of the closing portion 25, and further pushing of the inner member 12 is restricted.
As a result, the contents in the measurement space 27 are introduced to the inside of the extraction cylinder portion 32 through the supply hole 32A, and are extracted to the outside through the extraction hole 12A. Further, the air introduced into the extraction cylinder portion 32 through the extraction hole 12A passes through the air intake hole 32B formed inside the outer member 11 along the central axis O rather than the supply hole 32A. Are introduced into the measuring space 27. For this reason, the internal pressure of the measuring space 27 is unlikely to decrease, and the occurrence of pulsation of the content to be poured out is reduced or avoided.

When measuring and dispensing the contents again, first, the inner member 12 is pulled out from the outer member 11 along the central axis O by picking the operation piece 32C. When the inner member 12 is pulled out, the dispensing cylinder part 32 is separated from the introduction hole 23A to open the introduction hole 23A, and the closing part 25 closes the supply hole 32A and the air intake hole 32B. Thereby, the contents of the container main body 2 are introduced into the measuring space 27. The method for pouring the contents filled in the measuring space 27 is the same as described above. When the inner member 12 is pulled out from the outer member 11 along the central axis O, the lid member 13 is attached to the upper end portion of the extraction tube portion 32 and the inner member 12 is pulled by pulling the lid member 13. It may be pulled out from.
As described above, the metered content dispenser 1 is used to dispense the quantitative content.

According to the metering dispenser 1 configured as described above, when the contents introduced into the metering space 27 through the dispensing hole 12A are dispensed, the metering is performed through the dispensing hole 12A and the air intake hole 32B. External air is taken into the space 27. As a result, the contents can be poured out while suppressing the pulsation at the time of dispensing, and the dispensing time of the contents in the measurement space 27 can be shortened.
Further, the inner member 12 is fixed to the outer member 11 by opening the introduction hole 23A and locking the first and second locking protrusions 22A and 31A with the supply hole 32A and the air intake hole 32B closed. On the other hand, since further pulling out is suppressed, the relative axial positions of the inner member 12 and the outer member 11 can be adjusted easily and accurately.
Furthermore, by attaching the lid 13 to the upper end portion of the extraction cylinder portion 32, it is possible to suppress foreign matters such as dust from adhering to the extraction hole 12A. In addition, the lid 13 is detached from the upper end of the dispensing cylinder 32 by pulling the lid 13 and the first and second locking projections 22A and 31A are locked, so that the inner member 12 is not touched. The inner member 12 can be pulled out from the outer member 11, and content can be prevented from adhering to the hand.

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, although the outer member is screwed into the mouth portion, the outer member may be attached to the mouth portion by other methods such as fitting into the mouth portion. The outer member may be attached to the mouth using another mounting member.
A lid is attached to the upper end of the extraction cylinder, but the lid may not be attached. In addition, the lid body is configured to be detached from the dispensing cylinder portion when pulled in the central axis direction with the first and second locking projections locked together, in order to release the lid body. It is good also as a structure which requires another operation. Further, the lid may be configured to be detached from the dispensing cylinder portion before the first and second locking projections are locked to each other in the step of measuring and dispensing the contents.

The locking portion formed on each of the outer member and the inner member is engaged with the second locking protrusion protruding toward the radially outer side from the lower side with respect to the first locking protrusion protruding toward the radially inner side. Although it is configured to stop, for example, the locking portion formed on the outer member is an annular locking groove, and the locking groove is configured to lock the second locking protrusion, etc. May be changed as appropriate.
Moreover, it is good also as a structure which latches a pouring cylinder part to the lower end of the obstruction | occlusion cylinder part. In this case, for example, the dispensing cylinder part is formed by fitting a bottomed cylindrical lower half body and a cylindrical upper half body that are divided into two vertically with the center in the vertical direction as the center. . Here, an air intake hole is formed in an intermediate portion in the vertical direction of the lower half body, and a locking projection that can be locked to the lower end of the closed cylinder portion at the lower end of the lower half body Projecting outward in the radial direction. A communication hole is formed in the lower end portion of the upper half.
In addition, it is not necessary to form a latching | locking part in an outer side member and an inner side member.

A pair of locking pieces are provided, but one or more locking pieces may be provided.
The closing cylinder part is fitted inside the second sliding cylinder part, but may be formed integrally with the upper member of the measuring part. In this case, the upper member and the lower member are not divided into two parts up and down around the center in the vertical direction of the measuring part, and are divided into two parts above and below the center in the vertical direction. Note that, depending on the structure of the metering dispenser, the metering unit may be integrally formed without being divided into the lower and upper members.
The outer member has the first and second sliding tube portions. If the outer member can stably move back and forth with respect to the inner member, one or both of the first and second sliding tube portions can be used. It may not have.
The central axis of the metering dispenser need not coincide with the central axis of the container body, and the central axis of the metering dispenser may be inclined with respect to the central axis of the container body. In such a metering dispenser, more favorable operability can be obtained particularly when a handle is provided on the container body.
The metering dispenser need only be inverted so that the dispensing hole faces downward when measuring and dispensing the contents, and does not need to be inverted so that it is completely inverted.

  According to the present invention, industrial applicability is recognized for a metering dispenser that can smoothly dispense the weighed contents.
