Description

  The present invention allows the contents to be poured out by supplying the contents from the container body to the inside of the shell member by pulling up the movable stopper exposed from the shell member attached to the mouth of the container body. It is related with the extraction container which provided the extractor which carries out and synchronized raising of the said movable stopper with removal of the cap.

In the dispensing container, an engaging portion (first engaging portion) that bulges outward in an annular shape is provided around the tip of the movable stopper, and the engaged portion (first engaging portion) provided on the back surface of the cap. There is a configuration in which the movable stopper is pulled up simultaneously with the removal of the cap by detachably engaging the two engaging portions) (see, for example, Patent Document 1).
Japanese Patent No. 3759428

  However, the above engagement is generally realized by a configuration in which an engaged portion provided on the cap is undercut fitted (fitted with a catch due to a step) to an engaging portion provided on the movable stopper. Therefore, when the engaging portion of the cap is disengaged from the engaged portion of the movable plug, the cap is disengaged so as to repel each other, so that the movable plug, which has been raised by the reaction force, may be pushed down again.

  Such lowering of the movable stopper prevents the formation of the flow path realized by reliably pushing up the movable stopper, so that the movable stopper is lifted at the same time as the movable stopper is lifted at the same time when the cap is opened. A complicated operation is forced on the user.

  On the other hand, a method of restricting the vertical movement of the movable plug by giving resistance to the movable plug with a shell member is also conceivable. A new problem arises that the up-and-down movement) is impaired.

  Further, when manufacturing an object, product variations such as dimensional errors cannot be avoided, but in the case of a configuration in which the engaged portion is detachably engaged with the engaging portion, the variation greatly affects. Sometimes. For this reason, even if the product is produced as the same standard product, the engaged part is excessively engaged with the engaging part and the mutual engagement is difficult to be released. There may be a mixture of products that are small in engagement and easily disengaged from each other.

  In particular, in a product that has a high fitting strength and is difficult to release the engagement, the reaction force generated after the cap is removed is large, so that the movable stopper is easily pushed down. For this reason, there is an increasing demand for products that can be disengaged with a certain appropriate force regardless of manufacturing variations while pulling up the movable stopper.

  An object of the present invention is to pull up the movable plug simultaneously with the removal of the cap by detachably engaging the second engagement portion provided on the back side of the cap with the first engagement portion provided on the movable plug. An object of the present invention is to provide a novel dispensing container that is easy to use and enables reliable dispensing by a single operation without forcing the user to perform complicated operations.

The dispensing container of the present invention has a container body that has a mouth portion and is filled with contents inside, and
A shell member attached to the mouth of the container body, and the contents from the container body can be supplied to the inside of the shell member by pulling up the movable stopper exposed from the shell member. A dispenser that enables the dispensing of
It has a top wall arranged on the upper side of the dispenser, and includes a cap that is detachably attached to the mouth of the container body.
When the cap is closed from the top wall of the cap, the peripheral wall surrounding the movable plug is suspended, and the inner surface of the peripheral wall is extended to the first engagement portion that bulges from the outer surface of the movable plug when the cap is closed. A second container that is detachably engaged, and is a dispensing container that raises the movable stopper simultaneously with the removal of the cap,
A plurality of the second engaging portions are provided at intervals along the vertical direction, and the height of the second engaging portions is sequentially lowered as it goes downward.

  As the first engaging portion provided in the movable stopper, it was formed in an annular shape around the tip spout (axis) or swelled at intervals around the tip spout (axis) and formed intermittently And the like. However, when expanding around the tip spout (axis) with an interval, it is of course arranged so that the engagement with the second engagement portion provided on the cap is reliably realized.

  On the other hand, the second engaging portion provided on the cap is also spaced around the axis along the inner surface of the peripheral wall and the rib bulged around the axis along the inner surface of the peripheral wall so as to surround the movable plug. And a plurality of ribs formed intermittently. When the second engaging portion is an intermittent rib, the rib (intermittent portion) can be arranged so as to alternate with the rib (intermittent portion) adjacent in the axial direction around the axis. However, it is of course arranged so that the engagement with the first engagement portion provided on the movable stopper is reliably realized even when the gap is expanded around the axis along the inner surface of the peripheral wall. is there.

  When the height of the second engagement portion is gradually decreased as it goes downward, for example, the height of the second engagement portion located in the middle between the upper and lower sides is set as a reference dimension, There is a method of increasing the height while decreasing the height of the second engaging portion on the lower side. Moreover, when providing the said 2nd engaging part in an up-down (axis) direction, the space | interval can be adjusted suitably, but each 2nd engaging part cancels | releases each engagement with the 1st engaging part of a movable stopper, respectively. It is preferable to take such an interval.

  The cap may be formed of a single member, or may have a double wall structure of an interior body and an exterior body, and the second engagement portion may be provided on the interior body. As long as the cap is configured to be removed upward from the container body, the cap may be screwed or detachably undercut fitted to the container body.

  In the present invention, on the inner surface of the peripheral wall depending from the top wall of the cap, by providing a plurality of second engaging portions at intervals along the vertical direction (cap axis direction), in a state where the cap is closed, Of the plurality of second engaging portions, the second engaging portion at the uppermost stage is engaged with the first engaging portion provided on the movable stopper. And since the height of the said 2nd engaging part becomes low sequentially as it goes below, the 2nd engaging part in the uppermost stage has the highest engaging force (fitting strength) with respect to the 1st engaging part. The other second engaging portions are configured such that the fitting strength is gradually reduced downward.

  For this reason, when the cap is initially lifted, the movable plug is pulled up with the second engaging portion at the top of the plurality of second engaging portions being caught by the first engaging portion of the movable plug. When a force exceeding the fitting strength is applied, the engagement is released. At this time, if the height of the second engaging portion in the uppermost stage is appropriate in relation to the first engaging portion provided in the movable stopper, the fitting between the second engaging portion and the first engaging portion is performed. Since the combined strength is also appropriate, when the first engaging part of the movable plug gets over the second engaging part of the uppermost stage and the mutual engagement is released, the movable plug is flipped downward, so that It will not be pushed down.

  On the other hand, the height of the second engaging portion at the uppermost stage is not appropriate in relation to the first engaging portion provided in the movable stopper, and the fitting between the second engaging portion and the first engaging portion is not appropriate. When the combined strength is excessive, the movable stopper is elastically moved downward by the uppermost second engaging portion when the first engaging portion is disengaged from the uppermost second engaging portion. There is a case where Even in this case, it is possible to pull up the movable stopper again by engaging another second engaging portion existing below the second engaging portion in the uppermost stage with the first engaging portion. .

  Moreover, since the other second engaging portion has a lower fitting strength than the uppermost second engaging portion, the engagement is released with a force weaker than the initial fitting strength. According to such a configuration, as the engagement with the second engagement portion is released, the force repelled downward by the second engagement portion (reaction force applied to the first engagement portion) is weakened, so that the movable plug Pushing down can be suppressed.

  That is, according to the present invention, even if the movable plug is pulled up simultaneously with the removal of the cap by engaging the second engaging portion of the cap with the first engaging portion of the movable plug, the cap can be moved along with the release of the engagement. Since the plug is not pushed down again, it is possible to reliably dispense by one operation without forcing a complicated operation to cause the user to lift the movable plug again. Therefore, according to the present invention, it is possible to provide a novel dispensing container that is easy to use.

  In addition, even if manufacturing variation occurs in the second engagement portion of the cap or the first engagement portion of the movable stopper, any one of the plurality of second engagement portions provided in the cap is associated with the first engagement portion. In order to compensate for variations such as dimensional errors in the first and second engaging portions, the engagement can be released with a certain appropriate force regardless of manufacturing variations.

  According to the present invention, the second engaging portion related to the cap may be at least two stages in the vertical direction, but preferably three or more stages are more reliably engaged with the second engaging portion of the cap. The first engaging portion of the combined movable stopper can be released gently.

  In particular, if the second engagement portion is provided in three stages at intervals in the axial direction, the upper engagement can be achieved by using the second engagement portion existing in the middle as a reference. The existing second engaging portion is hooked larger than the second engaging portion existing in the middle stage, and the second engaging portion existing in the lower stage is hooked smaller than the second engaging portion existing in the middle stage.

  In other words, at least if the second engagement portion is provided in three stages with an interval in the axial direction, it is possible to consider both when the dimensional tolerance is large and when it is small. It is possible to prevent the movable stopper from being pushed down in consideration of the tolerance. Moreover, according to this structure, mass production can be realized at low cost.

  In addition, if the second engagement portion is an intermittent rib formed around the axis, the engagement area is efficiently reduced, which is more effective in suppressing the flipping that occurs when the engagement is disengaged. .

  Furthermore, when the second engagement portion is an intermittent rib, the engagement function with the cap is ensured by disposing the rib so that intermittent portions adjacent to each other in the axial direction are staggered around the axis. However, since the ribs adjacent to each other in the axial direction can be efficiently approached, the flipping that occurs when the engagement is disengaged can be suppressed while increasing the degree of freedom in designing the cap.

  In addition, if the cap according to the present invention has a double wall structure of an interior body and an exterior body, and the second engagement portion is provided in the interior body, it is only necessary to replace the interior body. By diverting, a highly versatile dispensing container can be obtained.

In the flow path C of the movable plug 13, an annular step 13 c that protrudes inward around the axis O is formed due to the difference in inner diameter between the movable plug base 13 a ₁ and the movable plug main body 13 a ₂ .

  On the other hand, an annular step 12g is formed in the shaft portion 12b. The annular step 12g is formed by recessing the outer edge of the tip portion around the axis O. The annular step 12g defines the bottom dead center of the movable plug 13 by contacting the annular step 13c of the movable plug 13. The tip of the movable plug 13 (hereinafter referred to as “movable plug tip”) 13e passes through the cylindrical portion 11c of the shell member 11 as shown in FIG. 1 and the like even when the movable plug 13 is at the bottom dead center. Exposed to the outside world.

Further, as shown in FIG. 2, the movable stopper 13 is formed with an annular step 13d protruding outward around the axis O due to the difference in outer diameter between the movable stopper base 13a ₁ and the movable stopper body 13a _2. Yes.

  On the other hand, the cylindrical part 11c is formed with an annular step 11e formed by recessing the inner edge of the lower end around the axis O in an annular shape. The annular step 11 e defines the top dead center of the movable plug 13 by contacting the annular step 13 d of the movable plug 13. Thereby, even if the movable stopper 13 reaches the top dead center, the movable stopper 13 does not fall off from the shell member 11 as shown in FIG.

Note that the inner surface of the cylindrical portion 11c, the seal portion 11f of the annular bulging integrally from a portion of the inner surface are integrally formed surrounding the movable cap body 13a _2. Seal portion 11f, by slidably contacting the movable cap body 13a _2, while ensuring the tightness between the movable cap body 13a _2, Smooth movable plug 13 along the shaft portion 12b Secure vertical movement.

On the other hand, as shown in FIG. 1 and the like, the annular recess 12c of the inner plug 12 is formed so as to accommodate the lower end portion of the movable plug base 13a ₁ when the movable plug 13 is pushed down. Therefore, in the present invention, the lower end outer face of the movable plug 13, to function as a seal portion for closing the supply holes A ₁ and slidably contact with the side surface f of the outer cylindrical portion 12c ₃ which form an annular recess 12c.

In particular, in this embodiment, as shown in FIG. 2, a part of the outer surface of the lower end of the movable plug base 13a ₁ is bulged around its axis O to provide a bulged portion 13f, and this bulged portion 13f Is an outer seal part (hereinafter referred to as “outer seal part 13f”). Thereby, by pulling up the movable stopper 13 with the removal of the cap 30 described later, as shown in FIG. 2, the supply hole A ₁ is opened to supply the contents from the container body 20 to the inside of the shell member 11, As shown in FIG. 1, the push-down of the movable stopper 13 accompanying the attachment of the cap 30 closes the supply hole A ₁ and prevents the contents from the container body 20 from being supplied inside the shell member 11.

On the other hand, the peripheral wall forming the movable plug body 13a ₂ has a plurality of communication paths that allow the storage space R formed between the shell member 11 and the inner plug 12 to communicate with the flow path C, as shown in FIG. A hole A ₃ is formed. The communication hole A ₃ is sealed without leading the contents in the storage space R to the flow path C when the movable plug 13 is pulled up and closed on the inner surface of the cylindrical portion 11 c as shown in FIG. On the other hand, the contents in the storage space R are guided to the flow path C as shown in FIG. Thus, in pulling the movable plug 13, while closing the communication hole A ₃ leading to the tip spout A ₂ in the cylindrical portion 11c, with depression of the movable plug 13, opening the communication hole A ₃ from the cylindrical portion 11c in may be pouring the contents of the shell member 11 from the tip spout a _2.

Reference numeral 14, as shown in FIG. 4, the tip of the shaft portion 12b, when depressing the movable plug 13 is an elastic valve for openably sealing the tip spout A ₂ from the channel C. The elastic valve 14 has a valve body 14a, and the valve body 14a is integrally formed through a corrugated elastic portion 14b.

A plurality of notches 14a ₃ are formed around the axis O of the pressing portion 14a ₂ . As a result, when the valve body 14a is pushed into the flow path C of the movable plug 13 against the urging force from the elastic portion 14b and the flange portion 14a ₁ is separated from the tip spout edge portion 13g, FIG. ), The content in the channel C can be poured out to the outside through a gap between the tip spout A ₂ and the notch 14a ₃ . Conversely, if released pushing the valve body 14a, as shown in FIG. 4 (a), the valve body 14a is to seal the tip spout A ₂ by the urging force of the elastic portion 14b.

Further, the movable plug 13 at its distal end spout A ₂ around the first engagement portion serving lip 13h bulged annularly disposed outwardly. In this embodiment, the lip 13h is detachably undercut fitted to the rib 31c, which is the second engaging portion provided on the inner surface of the peripheral wall 31b suspended from the back side of the cap 30, so that the cap 30 is shown in FIG. Simultaneously with the removal, the movable stopper 13 is configured to be pulled up.

  The cap 30 has a double wall structure of an interior body 31 and an exterior body 32. As shown in FIG. 1, the interior body 31 has a top wall 31a disposed on the upper side of the metering dispenser 10, and the cap 30 is closed from the top wall 31a as shown in FIG. Sometimes, the peripheral wall 31b surrounding the movable stopper 13 hangs down integrally.

  As shown in FIG. 5, a plurality of ribs 31 c are formed integrally on the inner surface of the peripheral wall 31 b, with a part of the inner surface bulging around the axis O at intervals. As will be described later, the ribs 31c in this embodiment are arranged in three stages in the direction of the axis O, and as shown in FIG. 1, when the cap 30 is closed, the ribs 31c can be detachably attached to the lip 13h of the movable plug 13. To do.

  6 (a) and 6 (b) are main part sectional views showing ribs 31c related to the cap 30 shown in FIG. 5, and main part development views showing the peripheral wall 31b having the ribs 31c developed from the inside thereof. is there.

As shown in FIG. 6, the ribs 31c are provided in three stages at intervals along the vertical direction (axis O). More specifically, as shown in FIG. 6 (a), the uppermost rib (hereinafter referred to as “first rib”) 31c ₁ has the highest protrusion height H ₁ and then downwards. It becomes lower sequentially. That is, a rib (hereinafter referred to as “second rib”) 31c ₂ existing in the middle stage has a height H ₂ lower than that of the first rib 31c ₁ (H ₂ <H ₁ ), and a rib ( Hereinafter, 31c _{3 (referred to as} “third rib”) has a height H ₃ lower than that of the second rib 31c ₂ (H ₃ <H ₂ ). Therefore, the inner diameter of the cap peripheral wall formed by the tip of each rib is in the relationship of the first rib 31c ₁ <the second rib 31c ₂ <the third rib 31c ₃ .

Reference numerals L ₁ and L ₂ denote an interval between the first rib 31c ₁ and the second rib 31c ₂ in the direction of the axis O (hereinafter referred to as an “axis direction interval”), and a second rib 31c ₂ and a third rib 31c, respectively. ₃ in the direction of the axis O (hereinafter referred to as “axis direction spacing”). In this embodiment, the axial intervals L ₁ and L ₂ are configured to be equal.

As shown in FIG. 6B, the first rib 31c ₁ is intermittently provided with an interval D ₁ around the axis O along the inner surface of the peripheral wall 31b. Further, as shown in the figure, the third rib 31c ₃ is also provided intermittently with an interval D ₁ around the axis O along the inner surface of the peripheral wall 31b. In particular, in this embodiment, as shown in the figure, the first rib 31c ₁ and the third rib 31c ₃ are provided at positions aligned along the axis O.

On the other hand, as shown in FIG. 6B, the second rib 31c ₂ is also provided intermittently with an interval D ₂ around the axis O along the inner surface of the peripheral wall 31b. Then, the second ribs 31c ₂ are provided so as to be staggered around the axis O with respect to the first ribs 31c ₁ and the third ribs 31c _{3 as} shown in FIG. In the present embodiment, the second rib 31c ₂ is disposed at an intermediate position between the first rib 31c ₁ and the third rib 31c ₃ .

Here, FIGS. 7A to 7C are operation diagrams schematically showing the relationship between the rib 31c and the lip 13h, respectively. In the following description, the second rib 31c ₂ is a place to be engaged with the lip 13h of the height H ₂ second rib 31c ₂ as reference dimension, a state in which the lip 13h is not caught by the second rib 31c ₂ " The state of “small hook” and the state in which the lip 13 h is hooked on the second rib 31 c ₂ are “center value”, and the state in which the lip 13 h is excessively hooked on the second rib 31 c ₂ is “large hook”. State.

FIG. 7A is an operation diagram in the “small hanging” state. In this case, the engagement between the cap 30 and the movable stopper 13 is achieved by the fact that the first rib 31c ₁ is undercut-fitted with a catching margin ΔC ₁ with respect to the lip 13h due to the influence of product variation or the like. ing. For this reason, when the cap 30 is initially pulled up, the movable plug 13 is pulled up with the first rib 31c ₁ being hooked on the lip 13h among the plurality of ribs 31c. The hook is released.

In this case, if the rib 31c is a single-piece structure having only the second rib 31c ₂ as in the prior art, the movable plug 13 cannot be pulled up with the removal of the cap 30 in the first place. Since 31c ₁ is caught by the lip 13h, the movable stopper 13 can be pulled up with the removal of the cap 30.

In addition, since the catching margin ΔC ₁ is small in the first place and the fitting strength between the first rib 31c ₁ and the lip 13h is appropriate, even when the catch of the lip 13h from the first rib 31c ₁ is released, the movable plug 13 There is no reaction force to cause the depression of the. Further, even if the second rib 31c ₂ existing under the first rib 31c ₁ rises as the cap 30 is removed, it passes through the lip 13h so as not to cause a reaction force in the push-down direction on the movable plug 13. .

Therefore, even if the second rib 31c ₂ is “smallly hooked” with respect to the lip 13h due to the product variation or the like, the movable stopper 13 can be pulled up simultaneously with the removal of the cap 30. The movable stopper 13 is not pushed down again with the release of the combination.

FIG. 7B is an operation diagram in the “intermediate value” state. In this case, the cap 30 and the movable stopper 13 are engaged with each other in a state where the second rib 31c ₂ can be properly undercut and fitted with a hook allowance ΔC ₂ with respect to the lip 13h, but the cap 30 is actually closed. In the state, the first rib 31c ₁ is achieved by the undercut fitting with the catching margin ΔC ₁ with respect to the lip 13h.

For this reason, when the cap 30 is initially lifted, the movable plug 13 is pulled up with a high fitting strength in which the first rib 31c ₁ is hooked on the lip 13h. However, when a force exceeding the fitting strength is applied, the hook 30 is caught. Is released. In this case, the movable stopper 13, by the lip 13h is repelled downwards to the first rib 31c ₁ with the release of the engagement between the first rib 31c _1, which may be depressed again. However, when the second rib 31c ₂ existing under the first rib 31c ₁ is engaged with the lip 13h again, the movable plug 13 can be lifted with an appropriate fitting strength.

That is, the second rib 31c ₂ has a fitting strength with respect to the lip 13h of the movable plug 13 that is weaker than the first rib 31c ₁ and has a fitting strength that does not cause the movable plug 13 to be pushed down. _The engagement is released with a force weaker than ₁ (appropriate catching allowance ΔC ₂ ). Further, even if the third rib 31c ₃ existing under the second rib 31c ₂ rises as the cap 30 is removed, it passes through the lip 13h so as not to cause a reaction force in the push-down direction on the movable plug 13. .

Therefore, even if the first rib 31c ₁ is in an “intermediate value” state with respect to the lip 13h due to the influence of product variation, the movable stopper 13 can be properly lifted simultaneously with the removal of the cap 30, The movable stopper 13 is not pushed down again with the release of the engagement.

FIG. 7 (c) is an operation diagram in the state of “large”. In this case, the engagement between the cap 30 and the movable stopper 13 is a state in which the third rib 31c ₃ can be engaged with the lip 13h with the hook allowance ΔC ₃ , but in this case as well, the cap 30 is actually attached. In the closed state, the first rib 31c ₁ is achieved by the undercut fitting with a catch margin ΔC ₁ with respect to the lip 13h.

For this reason, the fitting strength is excessively high, and when the cap 30 is pulled up, the movable plug 13 is pulled up with the first rib 31c ₁ being caught by the lip 13h among the plurality of ribs 31c. When a force exceeding is applied, the hook is released.

In this case, the movable stopper 13, by the lip 13h is repelled downwards to the first rib 31c ₁ with the release of the engagement between the first rib 31c _1, there is a case to depress again. The same applies to the engagement between the second rib 31c ₂ and the lip 13h.

Further, when the cap 30 is pulled up, the movable plug 13 is pulled up with the third rib 31c ₃ hooked on the lip 13h. However, when a force exceeding the fitting strength is applied, the hook is released.

In this case, since the fitting strength of the third rib 31c ₃ is weaker than that of the first rib 31c ₁ and the second rib 31c ₂ , the engagement is released with a weaker force than these. Here, if the hooking allowance ΔC ₃ is appropriate, the fitting strength between the rib 31c ₃ and the lip 13h is also appropriate. Therefore, even if the hook of the lip 13h from the third rib 31c ₃ is released, the movable plug 13 is released. Since no reaction force is generated to cause the depression of the movable stopper 13, the depression of the movable stopper 13 can be suppressed.

Therefore, even if the second rib 31c ₂ is “hanging large” with respect to the lip 13h due to the product variation, the movable stopper 13 can be properly lifted simultaneously with the removal of the cap 30, and The movable stopper 13 is not pushed down again with the release of the engagement.

  In this embodiment, the cap 30 has a double wall structure of an interior body 31 and an exterior body 32, and the interior body 31 is provided with a rib 31c and a pressing projection 31d. However, the cap 30 is made of a single member. It may be a cap.

  Further, in this embodiment, with respect to the pressing of the movable stopper 13, by providing the pressing protrusion 31d on the back side of the cap 30, when the cap 30 is closed, as shown in FIG. The distal end 13e of the movable stopper 13 is configured to be pushed down.

  Next, the operation of this embodiment will be described.

In this embodiment, when the cap 30 is turned and pulled up to remove the cap 30 from the state shown in FIG. 1, any one of the ribs 31 c _{1 to} 31 c ₃ provided on the cap 30 in three stages is connected to the movable plug. Since the hook 13 is caught on the lip 13h, the movable stopper 13 is also pulled up together. Since the catch between the rib 31c and the lip 13h is disengaged at any suitable engagement (appropriate fitting strength) among the ribs 31c _{1 to} 31c ₃ , finally, as shown in FIG. After the movable stopper 13 is pulled up to the top dead center, the cap 30 is removed from the mouth 21 of the container body 20 without the movable stopper 13 being pushed back as the engagement is released.

By this pulling up, as shown in FIG. 2, the movable stopper 13 closes the communication hole A ₃ with the cylindrical portion 11c and opens the supply hole A ₁ . Thereby, if the container main body 20 is turned upside down so that the tip spout A ₂ faces downward, the contents of the container main body 20 are connected to the shell member 11 and the inner plug from the mouth portion 21 through the supply hole A _1. 12 is supplied into the storage space R formed between the two.

Then, if pushed again by such shed movable plug 13 to the scalp or the like, movable plug 13, to ensure the airtightness of the outer cylinder portion 12c ₃ of the annular recess 12c of the inner plug 12 via its outer face seal portion 13f while by descending, as shown in FIG. 4 (a), becomes a state of being pressed into the shell member 11, the supply holes a _1, although sealed as shown in the figure, the communication hole a ₃ is The storage space R is communicated with the flow path C.

However, in this embodiment, as shown in FIG. 4 (a), the valve element 14a continues to seal the tip spout A ₂ by the urging force of the elastic portion 14b. Thereby, a fixed amount of contents can be confined in the storage space between the shell member 11 and the inner plug 12. That is, in this embodiment, it is possible to always measure a certain amount of contents by an operation similar to the conventional one.

Moreover, even when the movable stopper 13 is pushed in, the tip spout A ₂ of the movable stopper 13 is sealed by the elastic valve 14 as shown in FIG. be moved to the object, never contents are scattered from the tip spout A _2.

  When the contents are poured out, as shown in FIG. 4 (b), if the valve body 14a protruding from the movable stopper 13 is pressed against the portion to be poured out (surface to be coated) and pushed in, the measurement is performed as in the conventional case. The dispensed contents can be dispensed according to the pushing time.

In the present invention, by providing a plurality of ribs 31c _{1 to} 31c ₃ at intervals along the vertical direction on the inner surface of the peripheral wall 31b depending from the top wall 31a of the cap 30, in a state where the cap 30 is closed, Of the plurality of ribs 31 c _{1 to} 31 c ₃ , the first rib 31 c ₁ is engaged with the lip 13 h provided on the movable plug 13. In addition, since the heights H _{1 to} H ₃ of the ribs 31c are gradually lowered toward the lower side, the first ribs 31c ₁ exhibit the highest engagement force (fitting strength) with respect to the lip 13h. The ribs 31c ₂ and 31c ₃ are configured such that their fitting strengths are gradually reduced downward.

Thus, by raising the cap 30, and finally ribs 31c ₁ ~31c ₃ proper fit strength in, will be raising the movable plug 13 by the engagement between the lip 13h, the engagement against the lip 13h The movable stopper 13 is not pushed down again by releasing the combination.

  That is, according to the present invention, even if the rib 31c of the cap 30 is engaged with the lip 13h of the movable plug 13 and the movable plug 13 is pulled up simultaneously with the removal of the cap 30, the movable plug 13 is released along with the release of the engagement. Is not pushed down again, so that reliable dispensing can be performed by one operation without forcing the user to push up the movable stopper 13 again. Therefore, according to the present invention, it is possible to provide a new metering container that is easy to use.

Moreover, even if the lip 13h to manufacturing variations of the ribs 31c or movable plug 13 of the cap 30, by a plurality of ribs 31c ₁ ~31c ₃ provided on the cap 30, complement the variations in dimensional errors or the like related to the engagement portion Therefore, the engagement can be released with a certain appropriate force regardless of manufacturing variations.

  According to the present invention, the rib 31c related to the cap 30 may be at least two stages, but if it is preferably three or more stages, the lip of the movable plug 13 engaged with the rib 31c of the cap 30 is preferable. 13h can be released more gently.

However, if the second engagement portion is provided in three stages with an interval in the direction of the axis O as in the present embodiment, the second engagement portion 31c ₂ existing in the middle step is used as a reference. Thus, the second engagement portion 31c ₁ existing in the upper stage is caught larger than the second engagement portion 31c ₂ , and the second engagement portion 31c ₃ existing in the lower stage is more than the second engagement portion 31c _2. It gets caught small.

  That is, at least if the second engagement portion is provided in three stages with an interval in the direction of the axis O, it is possible to consider both when the dimensional tolerance is large and when it is small, so the simplest structure, It is possible to prevent the movable stopper 13 from being pushed down in consideration of the size tolerance. Moreover, according to this structure, mass production can be realized at low cost.

Further, if the second engagement portion is intermittent ribs 31c _{1 to} 31c ₃ formed around the axis O, the engagement area is efficiently reduced, so that the repelling that occurs when the engagement is disengaged is reduced. More effective for suppression.

Furthermore, when the second engaging portion is an intermittent rib 31c, the rib 31c is engaged with the cap 30 if the intermittent portions adjacent to each other in the axis O direction are alternately arranged around the axis. The ribs 31c ₁ to 31c ₃ adjacent to each other in the direction of the axis O can be efficiently approached while ensuring the function, and thus the flipping that occurs when the engagement is disengaged is suppressed while increasing the design freedom of the cap 30. be able to.

  In addition, if the cap 30 has a double wall structure of the interior body 31 and the exterior body 32 and the second engagement portion is provided in the interior body as in this embodiment, it is only necessary to replace the interior body 31. By diverting the existing exterior body 32, the dispensing container 20 with high versatility can be obtained.

  The above description shows only one embodiment of the present invention, and various modifications can be made within the scope of the claims. For example, the lip of the movable stopper is provided around the tip, but the position can be changed as appropriate. In addition, the number of ribs arranged on the cap and the arrangement interval thereof can be appropriately changed. Furthermore, the external shape of the movable stopper may be a square shape instead of the cylindrical shape as in the present embodiment.

  Table 1 below shows a conventional dispensing container (comparative example) in which the second engagement portion is a single annular rib, and intermittent ribs in which the second engagement portion is formed around the axis. The comparison result with the extraction container (example) according to the above-described embodiment of the present invention in which the two engaging portions are arranged in three stages so as to be staggered in the axial direction is shown.

  The item of “undercut” in Table 1 indicates the configuration of the rib and lip. In “shape” in the same item, a single rib as a comparative example is indicated as “normal”, and the three-stage structure of the present example is indicated as “plurality”.

Further, the “hanging amount (one side)” means the hooking allowance ΔC ₁ to the position shown in FIG. 7 when the lip that is the first engaging portion and the rib that is the second engaging portion are engaged. ΔC ₃ (design value), and its unit system is mm (millimeter). In Table 1, the upper rib is indicated as “first stage”, and the lower rib is indicated as “third stage”.

  Further, in the comparison of the present example, as shown in the item “sample”, both the comparative example and the example are numbered 1 to 3 for each hook (in the table, “# 1” to “# 3”). ”) Were used.

  Furthermore, the “opening / closing speed” is not the rotational speed of the cap but the ascending speed along the axis O direction. The case of rising at 30 mm / second along the axial direction is defined as a standard (normal), and the case of rising at 3 mm / second and the case of rising at 60 mm / second are defined as “slow” and “fast”, respectively.

  “○” indicates that the cap could be opened in an optimal state without the movable stopper being pushed down as a result of the test, and “△” indicates that the movable stopper was slightly pushed down, but the sealing performance This shows the case where quantitative dispensing can be realized without any problems. However, “X” indicates a case where the movable stopper is pushed down and the sealing performance itself cannot be maintained, and the quantitative dispensing is hindered.

  As is clear from the results shown in Table 1, in the comparative example, the movable stopper is pushed down in any of the hanging allowances, whereas in the example, the cap is in any case of the hanging allowance. Regardless of the lifting speed, the movable stopper is not pushed down. Therefore, according to the present invention, it is clear that quantitative dispensing can be performed without pulling up the movable stopper again.

  The present invention can be applied to a product that requires a predetermined amount to be dispensed after weighing a certain amount, and includes, for example, a chemical solution such as a hair restorer and a cosmetic. Liquid and the like.
